6978934713 Makefile: explicitly set target name for autogenerated dependencies
"gcc -MF depfile -MMD -MP -c -o path/to/file.o" produces a makefile
snippet named "depfile" describing what files are needed to build the
target given by "-o".  When ccache versions before v3.0pre0~187 (Fix
handling of the -MD and -MDD options, 2009-11-01) run, they execute

	gcc -MF depfile -MMD -MP -E

instead to get the final content for hashing.  Notice that the "-c -o"
combination is replaced by "-E".  The result is a target name without
a leading path.

Thus when building git with such versions of ccache with
COMPUTE_HEADER_DEPENDENCIES enabled, the generated makefile snippets
define dependencies for the wrong target:

	$ make builtin/add.o
	GIT_VERSION = 1.7.8.rc3
	    * new build flags or prefix
	    CC builtin/add.o
	$ head -1 builtin/.depend/add.o.d
	add.o: builtin/add.c cache.h git-compat-util.h compat/bswap.h strbuf.h \

After a change in a header file, object files in a subdirectory are
not automatically rebuilt by "make":

	$ touch cache.h
	$ make builtin/add.o
	$

Luckily we can prevent trouble by explicitly supplying the name of the
target to ccache and gcc, using the -MQ option.  Do so.

e28efb1998 apply: diagnose incomplete submodule object name better
"git am -3" uses this function to build a tree that records how the
preimage the patch was created from would have looked like.  An
abbreviated object name on the index line is ordinarily sufficient
for us to figure out the object name the preimage tree would have
contained, but a change to a submodule by definition shows an object
name of a submodule commit which our repository should not have, and
get_sha1_blob() is not an appropriate way to read it (or get_sha1()
for that matter).

Use get_sha1_hex() and complain if we do not find a full object name
there.

We could read from the payload part of the patch to learn the full
object name of the commit, but the primary user "git rebase" has
been fixed to give us a full object name, so this should suffice
for now.

e2afb0be90 apply: simplify build_fake_ancestor()
The local variable sha1_ptr in the build_fake_ancestor() function
used to either point at the null_sha1[] (if the ancestor did not
have the path) or at sha1[] (if we read the object name into the
local array), but 7a98869 (apply: get rid of --index-info in favor
of --build-fake-ancestor, 2007-09-17) made the "missing in the
ancestor" case unnecessary, hence sha1_ptr, when used, always points
at the local array.

Get rid of the unneeded variable, and restructure the if/else
cascade a bit to make it easier to read.  There should be no
behaviour change.

4ae6d4699f git-am: record full index line in the patch used while rebasing
Earlier, a230949 (am --rebasing: get patch body from commit, not
from mailbox, 2012-06-26) learned to regenerate patch body from the
commit object while rebasing, instead of reading from the rebase-am
front-end.  While doing so, it used "git diff-tree" but without
giving it the "--full-index" option.

This does not matter for in-repository objects; during rebasing, any
abbreviated object name should uniquely identify them.

But we may be rebasing a commit that contains a change to a gitlink,
in which case we usually should not have the object (it names a
commit in the submodule).  A full object name is necessary to later
reconstruct a fake ancestor index for them.

7dac3f8321 gpg: close stderr once finished with it in verify_signed_buffer()
Failing to close the stderr pipe in verify_signed_buffer() causes
git to run out of file descriptors if there are many calls to
verify_signed_buffer(). An easy way to trigger this is to run

 git log --show-signature --merges | grep "key"

on the linux kernel git repo. Eventually it will fail with

 error: cannot create pipe for gpg: Too many open files
 error: could not run gpg.

Close the stderr pipe so that this can't happen.

a235e85cc8 git-p4.py: support Python 2.4

Take a cue from 460d1026 and provide an implementation of the

subproccess.check_call with calls to subprocess.call that check the return
status and raise a CalledProcessError exception if necessary.

The struct.pack_into in t/9802 can be converted into a single struct.pack
call which is available in Python 2.4.

An earlier conversion from fgets() to strbuf_getline() in the
codepath to read from /etc/mailname to learn the default host-part

line at the beginning of the buffer just like fgets().

The "username@" the caller has prepared in the strbuf, expecting the
function to append the host-part to it, was lost because of this.

5047822347 t9902: protect test from stray build artifacts
When you have random build artifacts in your build directory, left
behind by running "make" while on another branch, the "git help -a"
command run by __git_list_all_commands in the completion script that
is being tested does not have a way to know that they are not part
of the subcommands this build will ship.  Such extra subcommands may
come from the user's $PATH.  They will interfere with the tests that
expect a certain prefix to uniquely expand to a known completion.

Instrument the completion script and give it a way for us to tell
what (subset of) subcommands we are going to ship.

Also add a test to "git --help <prefix><TAB>" expansion.  It needs
to show not just commands but some selected documentation pages.

Based on an idea by Jeff King.

1187ec99b9 git-cvsimport.txt: cvsps-2 is deprecated
git-cvsimport relies on version 2 of cvsps and does not work with the
new version 3.  Since cvsps 3.x does not currently work as well as
version 2 for incremental import, document this fact.

Specifically, there is no way to make new git-cvsimport that supports
cvsps 3.x and have a seamless transition for existing users since cvsps
3.x needs a time from which to continue importing and git-cvsimport does
not save the time of the last import or import into a specific namespace
so there is no safe way to calculate the time of the last import.

50c5885e05 git-completion.bash: replace zsh notation that breaks bash 3.X
When commit d8b45314 began separating the zsh completion from the bash
completion, it introduced a zsh completion "bridge" section into the bash
completion script for zsh users to use until they migrated to the zsh
script.  The zsh '+=()' append-to-array notation prevents bash 3.00.15 on
CentOS 4.x from loading the completion script and breaks test 9902.  We can
easily work around this by using standard Bash array notation.

9db9eecfe5 attr: avoid calling find_basename() twice per path
find_basename() is only used inside collect_all_attrs(), called once
in prepare_attr_stack, then again after prepare_attr_stack()
returns. Both calls return exact same value. Reorder the code to do
the same task once. Also avoid strlen() because we knows the length
after finding basename.

711536bd4b attr: fix off-by-one directory component length calculation
94bc671 (Add directory pattern matching to attributes - 2012-12-08)
uses find_basename() to calculate the length of directory part in
prepare_attr_stack. This function expects the directory without the
trailing slash (as "origin" field in match_attr struct is without the
trailing slash). find_basename() includes the trailing slash and
confuses push/pop algorithm.

Consider path = "abc/def" and the push down code:

	while (1) {
		len = strlen(attr_stack->origin);
		if (dirlen <= len)
			break;
		cp = memchr(path + len + 1, '/', dirlen - len - 1);
		if (!cp)
			cp = path + dirlen;

dirlen is 4, not 3, without this patch. So when attr_stack->origin is
"abc", it'll miss the exit condition because 4 <= 3 is wrong. It'll
then try to push "abc/" down the attr stack (because "cp" would be
NULL). So we have both "abc" and "abc/" in the stack.

Next time when "abc/ghi" is checked, "abc/" is popped out because of
the off-by-one dirlen, only to be pushed back in again by the above
code. This repeats for all files in the same directory. Which means
at least one failed open syscall per file, or more if .gitattributes
exists.

This is the perf result with 10 runs on git.git:

986977847e rebase --preserve-merges: keep all merge commits including empty ones
Since 90e1818f9a  (git-rebase: add keep_empty flag, 2012-04-20)
'git rebase --preserve-merges' fails to preserve empty merge commits
unless --keep-empty is also specified.  Merge commits should be
preserved in order to preserve the structure of the rebased graph,
even if the merge commit does not introduce changes to the parent.

Teach rebase not to drop merge commits only because they are empty.

A special case which is not handled by this change is for a merge commit
whose parents are now the same commit because all the previous different
parents have been dropped as a result of this rebase or some previous
operation.

9a6dcb37bd contrib/vim: simplify instructions for old vim support
Rely on the upstream filetype.vim instead of duplicating its rules in
git's instructions for syntax highlighting support on pre-7.2 vim
versions.

The result is a shorter contrib/vim/README.  More importantly, it lets
us punt on maintenance of the autocmd rules.

So now when we fix the upstream gitsendemail rule in light of commit
eed6ca7, new git users stuck on old vim reading contrib/vim/README can
automagically get the fix without any further changes needed to git.

Once the world has moved on to vim 7.2+ completely, we can get rid of
these instructions, but for now if they are this simple it's
effortless to keep them.

283b365e45 t1402: work around shell quoting issue on NetBSD
The test fails for me on NetBSD 6.0.1 and reports:

	ok 1 - ref name '' is invalid
	ok 2 - ref name '/' is invalid
	ok 3 - ref name '/' is invalid with options --allow-onelevel
	ok 4 - ref name '/' is invalid with options --normalize
	error: bug in the test script: not 2 or 3 parameters to test-expect-success

The alleged bug is in this line:

	invalid_ref NOT_MINGW '/' '--allow-onelevel --normalize'

invalid_ref() constructs a test case description using its last argument,
but the shell seems to split it up into two pieces if it contains a
space.  Minimal test case:

	# on NetBSD with /bin/sh
	$ a() { echo $#-$1-$2; }
	$ t="x"; a "${t:+$t}"
	1-x-
	$ t="x y"; a "${t:+$t}"
	2-x-y
	$ t="x y"; a "${t:+x y}"
	1-x y-

	# and with bash
	$ t="x y"; a "${t:+$t}"
	1-x y-
	$ t="x y"; a "${t:+x y}"
	1-x y-

This may be a bug in the shell, but here's a simple workaround: Construct
the description string first and store it in a variable, and then use
that to call test_expect_success().

92f1c04243 Prevent space after directories in tcsh completion
If git-completion.bash returns a single directory as a completion,
tcsh will automatically add a space after it, which is not what the
user wants.

This commit prevents tcsh from doing this.

Also, a check is added to make sure the tcsh version used is recent
enough to allow completion to work as expected.

a45fb697f1 status: always report ignored tracked directories
When enumerating paths that are ignored, paths the index knows
about are not included in the result.  The "index knows about"
check is done by consulting the name hash, not the actual
contents of the index:

 - When core.ignorecase is false, directory names are not in the
   name hash, and ignored ones are shown as ignored (directories
   can never be tracked anyway).

 - When core.ignorecase is true, however, the name hash keeps
   track of the names of directories, in order to detect
   additions of the paths under different cases.  This causes
   ignored directories to be mistakenly excluded when
   enumerating ignored paths.

Stop excluding directories that are in the name hash when
looking for ignored files in dir_add_name(); the names that are
actually in the index are excluded much earlier in the callchain
in treat_file(), so this fix will not make them mistakenly
identified as ignored.

55292ea25d t5003: check if unzip supports symlinks
Only add a symlink to the repository if both the filesystem and
unzip support symlinks.  To check the latter, add a ZIP file
containing a symlink, created like this with InfoZIP zip 3.0:

	$ echo sample text >textfile
	$ ln -s textfile symlink
	$ zip -y infozip-symlinks.zip textfile symlink

If we can extract it successfully, we add a symlink to the test
repository for git archive --format=zip, or otherwise skip that
step.  Users can see the skipped test and perhaps run it again
with a different unzip version.

5ea2c847c5 archive-zip: write uncompressed size into header even with streaming
We record the uncompressed and compressed sizes and the CRC of streamed
files as zero in the local header of the file.  The actual values are
recorded in an extra data descriptor after the file content, and in the
usual ZIP directory entry at the end of the archive.

While we know the compressed size and the CRC only after we processed
the contents, we actually know the uncompressed size right from the
start.  And for files that we store uncompressed we also already know
their final size.

Do it like InfoZIP's zip and recored the known values, even though they
can be reconstructed using the ZIP directory and the data descriptors
alone.  InfoZIP's unzip worked fine before, but NetBSD's version
actually depends on these fields.

The uncompressed size is already set by sha1_object_info().  We just
need to initialize the compressed size to zero or the uncompressed size
depending on the compression method (0 means storing).  The CRC was
propertly initialized already.

709ca730f8 run-command: encode signal death as a positive integer
When a sub-command dies due to a signal, we encode the
signal number into the numeric exit status as "signal -
128". This is easy to identify (versus a regular positive
error code), and when cast to an unsigned integer (e.g., by
feeding it to exit), matches what a POSIX shell would return
when reporting a signal death in $? or through its own exit
code.

So we have a negative value inside the code, but once it
passes across an exit() barrier, it looks positive (and any
code we receive from a sub-shell will have the positive
form). E.g., death by SIGPIPE (signal 13) will look like
-115 to us in inside git, but will end up as 141 when we
call exit() with it. And a program killed by SIGPIPE but run
via the shell will come to us with an exit code of 141.

Unfortunately, this means that when the "use_shell" option
is set, we need to be on the lookout for _both_ forms. We
might or might not have actually invoked the shell (because
we optimize out some useless shell calls). If we didn't invoke
the shell, we will will see the sub-process's signal death
directly, and run-command converts it into a negative value.
But if we did invoke the shell, we will see the shell's
128+signal exit status. To be thorough, we would need to
check both, or cast the value to an unsigned char (after
checking that it is not -1, which is a magic error value).

Fortunately, most callsites do not care at all whether the
exit was from a code or from a signal; they merely check for
a non-zero status, and sometimes propagate the error via
exit(). But for the callers that do care, we can make life
slightly easier by just using the consistent positive form.

This actually fixes two minor bugs:

  1. In launch_editor, we check whether the editor died from
     SIGINT or SIGQUIT. But we checked only the negative
     form, meaning that we would fail to notice a signal
     death exit code which was propagated through the shell.

  2. In handle_alias, we assume that a negative return value
     from run_command means that errno tells us something
     interesting (like a fork failure, or ENOENT).
     Otherwise, we simply propagate the exit code. Negative
     signal death codes confuse us, and we print a useless
     "unable to run alias 'foo': Success" message. By
     encoding signal deaths using the positive form, the
     existing code just propagates it as it would a normal
     non-zero exit code.

The downside is that callers of run_command can no longer
differentiate between a signal received directly by the
sub-process, and one propagated. However, no caller
currently cares, and since we already optimize out some
calls to the shell under the hood, that distinction is not
something that should be relied upon by callers.

Fix the same logic in t/test-terminal.perl for consistency [jc:
raised by Jonathan in the discussion].

22f0dcd963 archive-tar: split long paths more carefully
The name field of a tar header has a size of 100 characters.  This limit
was extended long ago in a backward compatible way by providing the
additional prefix field, which can hold 155 additional characters.  The
actual path is constructed at extraction time by concatenating the prefix
field, a slash and the name field.

get_path_prefix() is used to determine which slash in the path is used as
the cutting point and thus which part of it is placed into the field
prefix and which into the field name.  It tries to cram as much into the
prefix field as possible.  (And only if we can't fit a path into the
provided 255 characters we use a pax extended header to store it.)

If a path is longer than 100 but shorter than 156 characters and ends
with a slash (i.e. is for a directory) then get_path_prefix() puts the
whole path in the prefix field and leaves the name field empty.  GNU tar
reconstructs the path without complaint, but the tar included with
NetBSD 6 does not: It reports the header to be invalid.

For compatibility with this version of tar, make sure to never leave the
name field empty.  In order to do that, trim the trailing slash from the
part considered as possible prefix, if it exists -- that way the last
path component (or more, but not less) will end up in the name field.

9be1980bb9 clone: support atomic operation with --separate-git-dir
Since b57fb80a7d (init, clone: support --separate-git-dir for .git file)
git clone supports the --separate-git-dir option to create the git dir
outside the work tree. But when that option is used, the git dir won't be
deleted in case the clone fails like it would be without this option. This
makes clone lose its atomicity as in case of a failure a partly set up git
dir is left behind. A real world example where this leads to problems is
when "git submodule update" fails to clone a submodule and later calls to
"git submodule update" stumble over the partially set up git dir and try
to revive the submodule from there, which then fails with a not very user
friendly error message.

Fix that by updating the junk_git_dir variable (used to remember if and
what git dir should be removed in case of failure) to the new value given
with the --seperate-git-dir option. Also add a test for this to t5600 (and
while at it fix the former last test to not cd into a directory to test
for its existence but use "test -d" instead).

81127d74c4 tests: turn on test-lint by default
The test Makefile knows about a few "lint" checks for common
errors. However, they are not enabled as part of "make test"
by default, which means that many people do not bother
running them. Since they are both quick to run and accurate
(i.e., no false positives), there should be no harm in
turning them on and helping submitters catch errors earlier.

We could just set:

  TEST_LINT = test-lint

to enable all tests. But that would be unnecessarily
annoying later on if we add slower or less accurate tests
that should not be part of the default. Instead, we name the

particular, that means the configuration procedure repeats whenever

support "./configure --version" and "./configure --help"), making
bisecting painfully slow.

The intent was to make the reconfiguration process only trigger for
changes to configure.ac's logic.  Tweak the Makefile rule to match
that intent by depending on configure.ac instead of configure.

they're less likely to conflict with a git-* command somewhere in the
$PATH.

I have a git-ss command in my path which prevents the 'ss' alias from
being used.  This command will always fail for git.git, causing the test
to fail.  Even if the command succeeded, that would be a false success
for the test since the alias wasn't actually used.  A longer, more
descriptive name will make it much less likely that somebody has a
command in their $PATH which will shadow the alias created for the test.

While here, use a longer name for the 'test' alias as well since that is
also short and meaningful enough to make it not unlikely that somebody
would have a command in their $PATH which will shadow that as well.

6cf9614df6 git-remote-helpers.txt: document invocation before input format
In the distant past, the order things were documented was
'Invocation', 'Commands', 'Capabilities', ...

Then it was decided that before giving a list of Commands, there
should be an overall description of the 'Input format', which was
a wise decision. However, this description was put as the very
first thing, with the rationale that any implementor would want
to know that first.

However, it seems an implementor would actually first need to
know how the remote helper will be invoked, so moving
'Invocation' to the front again seems logical. Moreover, we now
don't switch from discussing the input format to the invocation
style and then back to input related stuff.

35ffe75831 merge-tree: fix d/f conflicts
The previous commit documented two known breakages revolving around
a case where one side flips a tree into a blob (or vice versa),
where the original code simply gets confused and feeds a mixture of
trees and blobs into either the recursive merge-tree (and recursing
into the blob will fail) or three-way merge (and merging tree contents
together with blobs will fail).

Fix it by feeding trees (and only trees) into the recursive
merge-tree machinery and blobs (and only blobs) into the three-way
content level merge machinery separately; when this happens, the
entire merge has to be marked as conflicting at the structure level.

b3f1280ec7 refs: do not use cached refs in repack_without_ref
When we delete a ref that is packed, we rewrite the whole
packed-refs file and simply omit the ref that no longer
exists. However, we base the rewrite on whatever happens to
be in our refs cache, not what is necessarily on disk. That
opens us up to a race condition if another process is
simultaneously packing the refs, as we will overwrite their
newly-made pack-refs file with our potentially stale data,
losing commits.

You can demonstrate the race like this:

  # setup some repositories
  git init --bare parent &&
  (cd parent && git config core.logallrefupdates true) &&
  git clone parent child &&
  (cd child && git commit --allow-empty -m base)

  # in one terminal, repack the refs repeatedly
  cd parent &&
  while true; do
	git pack-refs --all
  done

  # in another terminal, simultaneously push updates to
  # master, and create and delete an unrelated ref
  cd child &&
  while true; do
	git push origin HEAD:newbranch &&
	git commit --allow-empty -m foo
	us=`git rev-parse master` &&
	git push origin master &&
	git push origin :newbranch &&
	them=`git --git-dir=../parent rev-parse master` &&
	if test "$them" != "$us"; then
		echo >&2 "$them" != "$us"
		exit 1
	fi
  done

In many cases the two processes will conflict over locking
the packed-refs file, and the deletion of newbranch will
simply fail.  But eventually you will hit the race, which
happens like this:

  1. We push a new commit to master. It is already packed
     (from the looping pack-refs call). We write the new
     value (let us call it B) to $GIT_DIR/refs/heads/master,
     but the old value (call it A) remains in the
     packed-refs file.

  2. We push the deletion of newbranch, spawning a
     receive-pack process. Receive-pack advertises all refs
     to the client, causing it to iterate over each ref; it
     caches the packed refs in memory, which points at the
     stale value A.

  3. Meanwhile, a separate pack-refs process is running. It
     runs to completion, updating the packed-refs file to
     point master at B, and deleting $GIT_DIR/refs/heads/master
     which also pointed at B.

  4. Back in the receive-pack process, we get the
     instruction to delete :newbranch. We take a lock on
     packed-refs (which works, as the other pack-refs
     process has already finished). We then rewrite the
     contents using the cached refs, which contain the stale
     value A.

The resulting packed-refs file points master once again at
A. The loose ref which would override it to point at B was
deleted (rightfully) in step 3. As a result, master now
points at A. The only trace that B ever existed in the
parent is in the reflog: the final entry will show master
moving from A to B, even though the ref still points at A
(so you can detect this race after the fact, because the
next reflog entry will move from A to C).

We can fix this by invalidating the packed-refs cache after
we have taken the lock. This means that we will re-read the
packed-refs file, and since we have the lock, we will be
sure that what we read will be atomically up-to-date when we
write (it may be out of date with respect to loose refs, but
that is OK, as loose refs take precedence).

5a02966685 t9020: use configured Python to run the test helper
The test helper svnrdump_sim.py is used as "svnrdump" during the
execution of this test, but the arrangement was not optimal:

 - it relied on symbolic links;
 - unportable "export VAR=VAL" was used;
 - GIT_BUILD_DIR variable was not quoted correctly;
 - it assumed that the Python interpreter is in /usr/bin/ and
   called "python" (i.e. not "python2.7" etc.)

Rework this by writing a small shell script that spawns the right
Python interpreter, using the right quoting.

27f6342f61 t4014: fix arguments to grep
These "expect-failure" tests were not looking for the right string
in the patch file.  For example:

	grep "^ *"S. E. Cipient" <scipient@example.com>\$" patch5

was looking for "^ *S." in these three files:

    "E."
    "Cipient <scipient@example.com>$"
    "patch5"

With some implementations of grep, the lack of file "E." was
reported as an error, leading to the failure of the test.

With other implementations of grep, the pattern "^ *S." matched what
was in patch5, without diagnosing the missing files as an error, and
made these tests unexpectedly pass.

2060ed50e7 t9502: do not assume GNU tar
The check_snapshot function makes sure that no cruft outside the
repository hierarchy is added to the tar archive.  The output from
"tar tf" on the resulting archive is inspected to see if there is
anything that does not begin with "$prefix/".

There are two issues with this implementation:

 - Traditional tar implemenations that do not understand
   pax_global_header will write it out as if it is a plain file at
   the top-level;

 - Some implementations of tar do not add trailing slash when
   showing a directory entry (i.e. the output line for the entire
   archive will show "$prefix", not "$prefix/").

Fix them so that what we want to validate can be tested with
traditional tar implementations.

Email addresses in documentation are converted into mailto: hyperlinks
in the HTML output and footnotes in man pages.  This isn't desirable for
cases where the address is used as an example and is not valid.

Particularly annoying is the example "jane@laptop.(none)" which appears
in git-shortlog(1) as "jane@laptop[1].(none)", with note 1 saying:

	1. jane@laptop
	   mailto:jane@laptop

Fix this by escaping these email addresses with a leading backslash, to
prevent Asciidoc expanding them as inline macros.

In the case of mailmap.txt, render the address monospaced so that it
matches the block examples surrounding that paragraph.

eec3e7e406 cache-tree: invalidate i-t-a paths after generating trees
Intent-to-add entries used to forbid writing trees so it was not a
problem. After commit 3f6d56d (commit: ignore intent-to-add entries
instead of refusing - 2012-02-07), we can generate trees from an index
with i-t-a entries.

However, the commit forgets to invalidate all paths leading to i-t-a
entries. With fully valid cache-tree (e.g. after commit or
write-tree), diff operations may prefer cache-tree to index and not
see i-t-a entries in the index, because cache-tree does not have them.

3cf773e426 cache-tree: fix writing cache-tree when CE_REMOVE is present
entry_count is used in update_one() for two purposes:

1. to skip through the number of processed entries in in-memory index
2. to record the number of entries this cache-tree covers on disk

Unfortunately when CE_REMOVE is present these numbers are not the same
because CE_REMOVE entries are automatically removed before writing to
disk but entry_count is not adjusted and still counts CE_REMOVE
entries.

Separate the two use cases into two different variables. #1 is taken
care by the new field count in struct cache_tree_sub and entry_count
is prepared for #2.

bfae342c97 remote-testsvn: fix unitialized variable
In remote-test-svn, there is a parse_rev_note function to
parse lines of the form "Revision-number" from notes. If it
finds such a line and parses it, it returns 0, copying the
value into a "struct rev_note". If it finds an entry that is
garbled or out of range, it returns -1 to signal an error.

However, if it does not find any "Revision-number" line at
all, it returns success but does not put anything into the
rev_note. So upon a successful return, the rev_note may or
may not be initialized, and the caller has no way of
knowing.

gcc does not usually catch the use of the unitialized
variable because the conditional assignment happens in a
separate function from the point of use. However, when
compiling with -O3, gcc will inline parse_rev_note and
notice the problem.

We can fix it by returning "-1" when no note is found (so on
a zero return, we always found a valid value).

4a6385fe55 index-format.txt: clarify what is "invalid"
A cache-tree entry with a negative entry count is considered invalid
by the current Git; it records that we do not know the object name
of a tree that would result by writing the directory covered by the
cache-tree as a tree object.

Clarify that any entry with a negative entry count is invalid, but
the implementations must write -1 there. This way, we can later
decide to allow writers to use negative values other than -1 to
encode optional information on such invalidated entries without
harming interoperability; we do not know what will be encoded and
how, so we keep these other negative values as reserved for now.

53474eb92f contrib: update stats/mailmap script
This version changes quite a few things:

  1. The original parsed the mailmap file itself, and it did
     it wrong (it did not understand entries with an extra
     email key).

     Instead, this version uses git's "%aE" and "%aN"
     formats to have git perform the mapping, meaning we do
     not have to read .mailmap at all, but still operate on
     the current state that git sees (and it also works
     properly from subdirs).

  2. The original would find multiple names for an email,
     but not the other way around.

     This version can do either or both. If we find multiple
     emails for a name, the resolution is less obvious than
     the other way around. However, it can still be a
     starting point for a human to investigate.

  3. The original would order only by count, not by recency.

     This version can do either. Combined with showing the
     counts, it can be easier to decide how to resolve.

  4. This version shows similar entries in a blank-delimited
     stanza, which makes it more clear which options you are
     picking from.

75ed918bda Add file completion to tcsh git completion.
For bash completion, the option '-o bashdefault' is used to indicate
that when no other choices are available, file completion should be
performed.  Since this option is not available in tcsh, no file
completion is ever performed.  Therefore, commands like 'git add ',
'git send-email ', etc, require the user to manually type out
the file name.  This can be quite annoying.

To improve the user experience we try to simulate file completion
directly in this script (although not perfectly).

The known issues with the file completion simulation are:
- Possible completions are shown with their directory prefix.
- Completions containing shell variables are not handled.
- Completions with ~ as the first character are not handled.

f8fb971eac fetch: ignore wildcarded refspecs that update local symbolic refs
In a repository cloned from somewhere else, you typically have a
symbolic ref refs/remotes/origin/HEAD pointing at the 'master'
remote-tracking ref that is next to it.  When fetching into such a
repository with "git fetch --mirror" from another repository that
was similarly cloned, the implied wildcard refspec refs/*:refs/*
will end up asking to update refs/remotes/origin/HEAD with the
object at refs/remotes/origin/HEAD at the remote side, while asking
to update refs/remotes/origin/master the same way.  Depending on the
order the two updates happen, the latter one would find that the
value of the ref before it is updated has changed from what the code
expects.

When the user asks to update the underlying ref via the symbolic ref
explicitly without using a wildcard refspec, e.g. "git fetch $there
refs/heads/master:refs/remotes/origin/HEAD", we should still let him
do so, but when expanding wildcard refs, it will result in a more
intuitive outcome if we simply ignore local symbolic refs.

As the purpose of the symbolic ref refs/remotes/origin/HEAD is to
follow the ref it points at (e.g. refs/remotes/origin/master), its
value would change when the underlying ref is updated.

Earlier commit da3efdb (receive-pack: detect aliased updates which
can occur with symrefs, 2010-04-19) fixed a similar issue for "git
push".

28dae1812b gitweb: Sort projects with undefined ages last
Sorting gitweb's project list by age ('Last Change') currently shows
projects with undefined ages at the head of the list. This gives a less
useful result when there are a number of projects that are missing or
otherwise faulty and one is trying to see what projects have been
updated recently.

Fix by sorting these projects with undefined ages at the bottom of the
list when sorting by age.

5b59708268 shortlog: fix wrapping lines of wraplen
A recent commit [1] fixed a off-by-one wrapping error.  As a
side-effect, the conditional in add_wrapped_shortlog_msg() to decide
whether to append a newline needs to be removed.  The function
should always append a newline, which was the case before the
off-by-one fix, because strbuf_add_wrapped_text() never returns a
value of wraplen; when it returns wraplen, the string does not end
with a newline, so this caller needs to add one anyway.

393050c32b sh-setup: work around "unset IFS" bug in some shells
With an unset IFS, field splitting is supposed to act as if IFS is
set to the usual SP HT LF, but Marc Branchaud reports that the shell
on FreeBSD 7.2 gets this wrong.

It is easy to set it to the default value manually, and it is also
safer in case somebody tries to save the old value away and restore,
e.g.

	$oIFS=$IFS
	IFS=something
	...
	IFS=$oIFS

while forgetting that the original IFS might be unset (which can be
coded but would be more involved).

a83b2b578c mingw_rmdir: do not prompt for retry when non-empty
in ab1a11be ("mingw_rmdir: set errno=ENOTEMPTY when appropriate"),
a check was added to prevent us from retrying to delete a directory
that is both in use and non-empty.

However, this logic was slightly flawed; since we didn't return
immediately, we end up falling out of the retry-loop, but right into
the prompting-loop.

Fix this by setting errno, and guarding the prompting-loop with an

There are two different static functions and one global function,
all of them called "merge_file()", with different signatures and
purposes.  Rename them all to reduce confusion in "git grep" output:

 * Rename the static one in merge-index to "merge_one_path(const char
   *path)" as that function is about asking an external command to
   resolve conflicts in one path.

 * Rename the global one in merge-file.c that is only used by
   merge-tree to "merge_blobs()", as the function takes three blobs and
   returns the merged result only in-core, without doing anything to
   the filesystem.

 * Rename the one in merge-recursive to "merge_one_file()", just to be
   fair.

Also rename merge-file.[ch] to merge-blobs.[ch].

f829a9eae6 git-remote-helpers.txt: document invocation before input format
In the distant past, the order things were documented was
'Invocation', 'Commands', 'Capabilities', ...

Then it was decided that before giving a list of Commands, there
should be an overall description of the 'Input format', which was
a wise decision. However, this description was put as the very
first thing, with the rationale that any implementor would want
to know that first.

However, it seems an implementor would actually first need to
know how the remote helper will be invoked, so moving
'Invocation' to the front again seems logical. Moreover, we now
don't switch from discussing the input format to the invocation
style and then back to input related stuff.

The getpass-implementation we use on Windows isn't at all ideal;
it works in raw-mode (as opposed to cooked mode), and as a result

Instead, use cooked mode to read a line at the time, allowing the
C run-time to process the input properly.

Since we set files to be opened in binary-mode by default on
Windows, introduce a FORCE_TEXT macro that expands to the "t"
modifier that forces the terminal to be opened in text-mode so we

1250857c6c launch_editor: propagate signals from editor to git
We block SIGINT and SIGQUIT while the editor runs so that
git is not killed accidentally by a stray "^C" meant for the
editor or its subprocesses. This works because most editors
ignore SIGINT.

However, some editor wrappers, like emacsclient, expect to
die due to ^C. We detect the signal death in the editor and
properly exit, but not before writing a useless error
message to stderr. Instead, let's notice when the editor was
killed by a terminal signal and just raise the signal on
ourselves.  This skips the message and looks to our parent
like we received SIGINT ourselves.

The end effect is that if the user's editor ignores SIGINT,
we will, too. And if it does not, then we will behave as if
we did not ignore it. That should make all users happy.

Note that in the off chance that another part of git has
ignored SIGINT while calling launch_editor, we will still
properly detect and propagate the failed return code from
the editor (i.e., the worst case is that we generate the
useless error, not fail to notice the editor's death).

913ef36093 launch_editor: ignore terminal signals while editor has control
The user's editor likely catches SIGINT (ctrl-C).  but if
the user spawns a command from the editor and uses ctrl-C to
kill that command, the SIGINT will likely also kill git
itself (depending on the editor, this can leave the terminal
in an unusable state).

Let's ignore it while the editor is running, and do the same
for SIGQUIT, which many editors also ignore. This matches
the behavior if we were to use system(3) instead of
run-command.

first test to chmod a file that we can see in the output (limited
by --stat-count) to demonstrate it.  Also make sure to use test_chmod
and compare the index and the tree, so that we can run this test
even on a filesystem without permission bits.

Later two tests are about fixes to separate issues that were
introduced and/or uncovered by Linus's patch as a side effect, but
the issues are not related to mode-only changes.  Remove chmod from
the tests.

e0a5227930 configure.ac: fix pthreads detection on Mac OS X
The configure script checks whether certain flags are required to use
pthreads. But it did not consider that *none* might be needed (as is the
case on Mac OS X). This lead to configure adding "-mt" to the list of
flags (which does nothing on OS X except producing a warning). This in
turn triggered a compiler warning on every single file.

To solve this, we now first check if pthreads work without extra flags.
This means the check is now order dependant, hence a comment is added
explaining this, and the reasons for it.

Note that it might be possible to write an order independent test, but
it does not seem worth the extra effort required for implementing and
testing such a solution, when this simple solution exists and works.

82dfc2c44e diff --stat: do not count "unmerged" entries
Even though we show a separate *UNMERGED* entry in the patch and
diffstat output (or in the --raw format, for that matter) in
addition to and separately from the diff against the specified stage
(defaulting to #2) for unmerged paths, they should not be counted in
the total number of files affected---that would lead to counting the
same path twice.

The separation done by the previous step makes this fix simple and
straightforward.  Among the filepairs in diff_queue, paths that
weren't modified, and the extra "unmerged" entries do not count as
total number of files.

a20d3c0de1 diff --stat: move the "total count" logic to the last loop
The diffstat generation logic, with --stat-count limit, is
implemented as three loops.

 - The first counts the width necessary to show stats up to
   specified number of entries, and notes up to how many entries in
   the data we need to iterate to show the graph;

 - The second iterates that many times to draw the graph, adjusts
   the number of "total modified files", and counts the total
   added/deleted lines for the part that was shown in the graph;

 - The third iterates over the remainder and only does the part to
   count "total added/deleted lines" and to adjust "total modified
   files" without drawing anything.

Move the logic to count added/deleted lines and modified files from
the second loop to the third loop.

This incidentally fixes a bug.  The third loop was not filtering
binary changes (counted in bytes) from the total added/deleted as it
should.  The second loop implemented this correctly, so if a binary
change appeared earlier than the --stat-count cutoff, the code
counted number of added/deleted lines correctly, but if it appeared
beyond the cutoff, the number of lines would have mixed with the
byte count in the buggy third loop.

ce45ea6a13 Support for git aliasing for tcsh completion
tcsh users sometimes alias the 'git' command to another name.  In
this case, the user expects to only have to issue a new 'complete'
command using the alias name.

However, the tcsh script currently uses the command typed by the
user to call the appropriate function in git-completion.bash, either
_git() or _gitk().  When using an alias, this technique no longer
works.

This change specifies the real name of the command (either 'git' or
'gitk') as a parameter to the script handling tcsh completion.  This
allows the user to use any alias for the 'git' or 'gitk' commands,
while still getting completion to work.

A check for the presence of ${HOME}/.git-completion.bash is also
added to help the user make use of the script properly.

may be reported twice per send_message. Now we warn about them earlier
and we also remove invalid addresses.

This also removes using of undefined values for string comparison
for invalid addresses in cc list processing.

8cac13dccb send-email: avoid questions when user has an ident
Currently we keep getting questions even when the user has properly
configured his full name and password:

  Who should the emails appear to be from?
  [Felipe Contreras <felipe.contreras@gmail.com>]

And once a question pops up, other questions are turned on. This is
annoying.

The reason it's safe to avoid this question is because currently the
script fails completely when the author (or committer) is not correct,
so we won't even be reaching this point in the code.

The scenarios, and the current situation:

1) No information at all, no fully qualified domain name

  fatal: empty ident name (for <felipec@nysa.(none)>) not allowed

2) Only full name

  fatal: unable to auto-detect email address (got 'felipec@nysa.(none)')

3) Full name + fqdm

  Who should the emails appear to be from?
  [Felipe Contreras <felipec@nysa.felipec.org>]

4) Full name + EMAIL

  Who should the emails appear to be from?
  [Felipe Contreras <felipe.contreras@gmail.com>]

5) User configured
6) GIT_COMMITTER
7) GIT_AUTHOR

All these are the same as 4)

After this patch:

1) 2) won't change: git send-email would still die

4) 5) 6) 7) will change: git send-email won't ask the user

This is good, that's what we would expect, because the identity is
explicit.

3) will change: git send-email won't ask the user

This is bad, because we will try with an address such as
'felipec@nysa.felipec.org', which is most likely not what the user
wants, but the user will get warned by default (confirm=auto), and if
not, most likely the sending won't work, which the user would readily
note and fix.

The worst possible scenario is that such mail address does work, and the
user sends an email from that address unintentionally, when in fact the
user expected to correct that address in the prompt. This is a very,
very, very unlikely scenario, with many dependencies:

1) No configured user.name/user.email
2) No specified $EMAIL
3) No configured sendemail.from
4) No specified --from argument
5) A fully qualified domain name
6) A full name in the geckos field
7) A sendmail configuration that allows sending from this domain name
8) confirm=never, or
8.1) confirm configuration not hitting, or
8.2) Getting the error, not being aware of it
9) The user expecting to correct this address in the prompt

In a more likely scenario where 7) is not the case (can't send from
nysa.felipec.org), the user will simply see the mail was not sent
properly, and fix the problem.

The much more likely scenario though, is where 5) is not the case
(nysa.(none)), and git send-email will fail right away like it does now.

So the likelihood of this affecting anybody seriously is very very slim,
and the chances of this affecting somebody slightly are still very
small. The vast majority, if not all, of git users won't be affected
negatively, and a lot will benefit from this.

78189bead3 git p4: catch p4 errors when streaming file contents
Error messages that arise during the "p4 print" phase of
generating commits were silently ignored.  Catch them,
abort the fast-import, and exit.

Without this fix, the sync/clone appears to work, but files that
are inaccessible by the p4d server will still be imported to git,
although without the proper contents.  Instead the errant files
will contain a p4 error message, such as "Librarian checkout
//depot/path failed".

249da4c0dc git p4: handle servers without move support
Support for the "p4 move" command was added in 8e9497c (git p4:
add support for 'p4 move' in P4Submit, 2012-07-12), which checks
to make sure that the client and server support the command.

But older versions of p4d may not handle the "-k" argument, and
newer p4d allow disabling "p4 move" with a configuration setting.
Check for both these cases by testing a p4 move command on bogus
filenames and looking for strings in the error messages.

95c0d4b68a git-send-email: fix fallback code in extract_valid_address()
In the fallback check, used when Email::Valid is not available, the
extract_valid_address() uses $1 without checking for success of matching
regex. The $1 variable may still hold the result of previous match,
which is the address when email address was in '<>' or be undefined
otherwise.

Now if match fails undefined value is always returned to indicate error.
The same value is used by Email::Valid->address() in that case.

Previously 'foo@bar' address was rejected by Email::Valid and fallback,
but '<foo@bar>' was rejected by Email::Valid, but accepted by fallback.

831a488b76 git-send-email: remove garbage after email address
In some cases it is useful to add additional information after the
email address on the Cc: footer in a commit log, for instance:

"Cc: Stable kernel <stable@vger.kernel.org> #v3.4 v3.5 v3.6"

However, git-send-email refuses to pick up such an invalid address
when the Email::Valid perl module is available, or just uses the
whole line as the email address.

In sanitize_address(), remove everything after the email address, so
that the result is a valid email address that makes Email::Valid
happy.

53e4c5dcab Teach rm to remove submodules when given with a trailing '/'
Doing a "git rm submod/" on a submodule results in an error:
	fatal: pathspec 'submod/' did not match any files
This is really inconvenient as e.g. using TAB completion in a shell on a
submodule automatically adds the trailing '/' when it completes the path
of the submodule directory. The user has then to remove the '/' herself to
make a "git rm" succeed. Doing a "git rm -r somedir/" is working fine, so
there is no reason why that shouldn't work for submodules too.

Teach git rm to not error out when a '/' is appended to the path of a
submodule. Achieve this by chopping off trailing slashes from the path
names given if they represent directories. Add tests to make sure that
logic only applies to directories and not to files.

af507944a2 gitweb: make remote_heads config setting work
Git configuration items can not contain underscores in their section
and bottom-level variable name; the 'remote_heads' feature can not
be enabled on a per-repository basis with that name.

This changes the git-config option to be `gitweb.remoteheads` but does
not change the gitweb.conf option, to avoid backwards compatibility
issues.  We strip underscores from keys before looking through
git-config output for them.

An existing check on keynames was overly eager to reject non-word
letters, but if we ever start using three-level names, the middle
level string can contain almost anything, so fix that as well while
we are in the vicinity.

d8b453149c completion: start moving to the new zsh completion
Zsh's bash completion emulation is buggy, not properly maintained, and
we have some workarounds in place for different bugs that appeared in
various versions.

Since I'm the only one that has worked on that code lately[1], it might make
snese to use the code I wrote specifically for git.

The advantages are:

 1) Less workarounds

   * No need to hack __get_comp_words_by_ref
   * No need to hack IFS or words

 2) Improved features

   * 'git show master' now properly adds a space at the end (IFS bug)
   * 'git checkout --conflict=' now properly returns the sub-items
     (missing feature)

 3) Consolidated code

   * It's all now in a single chunk, and it's basically the same as
     git-completion.zsh

Since there's some interest in moving the zsh-specific code out of this
script, lets go ahead and warn the users that they should be using
git-completion.zsh.

in the latest version of zsh, but still, there are issues.

There is no point going through all that pain; the emulation is easy to
achieve, and this patch works better than zsh's bash completion
emulation.

4e215131d2 submodule: display summary header in bold
Currently, 'git diff --submodule' displays output with a bold diff
header for non-submodules.  So this part is in bold:

    diff --git a/file1 b/file1
    index 30b2f6c..2638038 100644
    --- a/file1
    +++ b/file1

For submodules, the header looks like this:

    Submodule submodule1 012b072..248d0fd:

Unfortunately, it's easy to miss in the output because it's not bold.
Change this.

9673b8c392 tcsh-completion re-using git-completion.bash
The current tcsh-completion support for Git, as can be found on the
Internet, takes the approach of defining the possible completions
explicitly.  This has the obvious draw-back to require constant
updating as the Git code base evolves.

The approach taken by this commit is to to re-use the advanced bash
completion script and use its result for tcsh completion.  This is
achieved by sourcing the bash script and outputting the completion
result for tcsh consumption.

Three solutions were looked at to implement this approach with (C)
being retained:

  A) Modifications:
          git-completion.bash and new git-completion.tcsh

     Modify the existing git-completion.bash script to support
     being sourced using bash (as now), but also executed using bash.
     When being executed, the script will output the result of the
     computed completion to be re-used elsewhere (e.g., in tcsh).

     The modification to git-completion.bash is made not to be
     tcsh-specific, but to allow future users to also re-use its
     output.  Therefore, to be general, git-completion.bash accepts a
     second optional parameter, which is not used by tcsh, but could
     prove useful for other users.

     Pros:
       1- allows the git-completion.bash script to easily be re-used
       2- tcsh support is mostly isolated in git-completion.tcsh
     Cons (for tcsh users only):
       1- requires the user to copy both git-completion.tcsh and
          git-completion.bash to ${HOME}
       2- requires bash script to have a fixed name and location:
          ${HOME}/.git-completion.bash

  B) Modifications:
          git-completion.bash

     Modify the existing git-completion.bash script to support
     being sourced using bash (as now), but also executed using bash,
     and sourced using tcsh.

     Pros:
       1- only requires the user to deal with a single file
       2- maintenance more obvious for tcsh since it is entirely part
          of the same git-completion.bash script.
     Cons:
       1- tcsh support could affect bash support as they share the
          same script
       2- small tcsh section must use syntax suitable for both tcsh
          and bash and must be at the beginning of the script
       3- requires script to have a fixed name and location:
          ${HOME}/.git-completion.sh (for tcsh users only)

  C) Modifications:
          New git-completion.tcsh

     Provide a short tcsh script that generates another script
     which extends git-completion.bash.  This new script can be
     used by tcsh to perform completion.

     Pros:
       1- tcsh support is entirely isolated in git-completion.tcsh
       2- new tcsh script can be as complex as needed
     Cons (for tcsh users only):
       1- requires the user to copy both git-completion.tcsh and
          git-completion.bash to ${HOME}
       2- requires bash script to have a fixed name and location:
          ${HOME}/.git-completion.bash
       3- sourcing the new script will generate a third script

Approach (C) was selected avoid any modification to git-completion.bash.

d6991ceedc ident: keep separate "explicit" flags for author and committer
We keep track of whether the user ident was given to us
explicitly, or if we guessed at it from system parameters
like username and hostname. However, we kept only a single
variable. This covers the common cases (because the author
and committer will usually come from the same explicit
source), but can miss two cases:

  1. GIT_COMMITTER_* is set explicitly, but we fallback for
     GIT_AUTHOR. We claim the ident is explicit, even though
     the author is not.

  2. GIT_AUTHOR_* is set and we ask for author ident, but
     not committer ident. We will claim the ident is
     implicit, even though it is explicit.

This patch uses two variables instead of one, updates both
when we set the "fallback" values, and updates them
individually when we read from the environment.

Rather than keep user_ident_sufficiently_given as a
compatibility wrapper, we update the only two callers to
check the committer_ident, which matches their intent and
what was happening already.

In v1.5.6-rc0~56^2 (2008-05-04) "user_ident_explicitly_given"
was introduced as a global for communication between config,
ident, and builtin-commit.  In v1.7.0-rc0~72^2 (2010-01-07)
readers switched to using the common wrapper
user_ident_sufficiently_given().  After v1.7.11-rc1~15^2~18
(2012-05-21), the var is only written in ident.c.

Now we can make it static, which will enable further
refactoring without worrying about upsetting other code.

bdccd3c1fb test-lib: allow negation of prerequisites
You can set and test a prerequisite like this:

  test_set_prereq FOO
  test_have_prereq FOO && echo yes

You can negate the test in the shell like this:

  ! test_have_prereq && echo no

However, when you are using the automatic prerequisite
checking in test_expect_*, there is no opportunity to use
the shell negation.  This patch introduces the syntax "!FOO"
to indicate that the test should only run if a prerequisite
is not meant.

One alternative is to set an explicit negative prerequisite,
like:

  if system_has_foo; then
	  test_set_prereq FOO
  else
	  test_set_prereq NO_FOO
  fi

However, this doesn't work for lazy prerequisites, which
associate a single test with a single name. We could teach
the lazy prereq evaluator to set both forms, but the code
change ends up quite similar to this one (because we still
need to convert NO_FOO into FOO to find the correct lazy
script).

The cygwin project recently switched to a new implementation of the
windows api, now using header files from the mingw-64 project. These
new header files are incompatible with the way cygwin.c included the
old headers: cygwin.c can be compiled using the new or the older (mingw)
headers, but different files must be included in different order for each
to work. The new headers are in use only for the current release series
(based upon the v1.7.x dll version). The previous release series using
the v1.5 dll is kept available but unmaintained for use on older versions
of Windows. So, patch cygwin.c to use the new include ordering only if
the dll version is 1.7 or higher.

048b399192 gitweb.perl: fix %highlight_ext mappings
When commit 592ea41 refactored the list of extensions for
syntax highlighting, it failed to take into account perl's
operator precedence within lists. As a result, we end up
creating a dictionary of one-to-one elements when the intent
was to map mutliple related types to one main type (e.g.,
bash, ksh, zsh, and sh should all map to sh since they share
similar syntax, but we ended up just mapping "bash" to
"bash" and so forth).

This patch adds parentheses to make the mapping as the
original change intended. It also reorganizes the list to
keep mapped extensions together.

0e18bcd5e9 reencode_string(): introduce and use same_encoding()
Callers of reencode_string() that re-encodes a string from one
encoding to another all used ad-hoc way to bypass the case where the
input and the output encodings are the same.  Some did strcmp(),
some did strcasecmp(), yet some others when converting to UTF-8 used
is_encoding_utf8().

Introduce same_encoding() helper function to make these callers use
the same logic.  Notably, is_encoding_utf8() has a work-around for
common misconfiguration to use "utf8" to name UTF-8 encoding, which
does not match "UTF-8" hence strcasecmp() would not consider the
same.  Make use of it in this helper function.

c2b3af0537 cvsimport: work around perl tzset issue
On many platforms, the first invocation of localtime_r will
check $TZ in the environment, but subsequent invocations
will use a cached value. That means that setting $ENV{TZ} in
the middle of the program may or may not have an effect on
later calls to localtime.  Perl 5.10.0 and later handles
this automatically for us, but we try to remain portable
back to 5.8. Work around it by calling tzset ourselves.

2e736fd5e9 remote-curl: retry failed requests for auth even with gzip
Commit b81401c taught the post_rpc function to retry the
http request after prompting for credentials. However, it
did not handle two cases:

  1. If we have a large request, we do not retry. That's OK,
     since we would have sent a probe (with retry) already.

  2. If we are gzipping the request, we do not retry. That
     was considered OK, because the intended use was for
     push (e.g., listing refs is OK, but actually pushing
     objects is not), and we never gzip on push.

This patch teaches post_rpc to retry even a gzipped request.
This has two advantages:

  1. It is possible to configure a "half-auth" state for
     fetching, where the set of refs and their sha1s are
     advertised, but one cannot actually fetch objects.

     This is not a recommended configuration, as it leaks
     some information about what is in the repository (e.g.,
     an attacker can try brute-forcing possible content in
     your repository and checking whether it matches your
     branch sha1). However, it can be slightly more
     convenient, since a no-op fetch will not require a
     password at all.

  2. It future-proofs us should we decide to ever gzip more
     requests.

df126e108b remote-curl: hoist gzip buffer size to top of post_rpc

compute the gzip body and its size inside the "use_gzip"

ends, but not the size. Let's remember both, which will

If you remove a submodule, in order to keep the repository so that
"git checkout" to an older commit in the superproject history can
resurrect the submodule, the real repository will stay in $GIT_DIR
of the superproject.  A later "git submodule add $path" to add a
different submodule at the same path will fail.  Diagnose this case
a bit better, and if the user really wants to add an unrelated
submodule at the same path, give the "--name" option to give it a
place in $GIT_DIR of the superproject that does not conflict with
the original submodule.

The submodule sync command was somehow left out when

Teach sync to handle the --recursive switch by recursing
when we're in a submodule we are sync'ing.

Change the report during sync to show submodule-path
instead of submodule-name to be consistent with the other

e15bec0ec3 submodule status: remove unused orig_* variables
When renaming orig_args to orig_flags in 98dbe63d (submodule: only
preserve flags across recursive status/update invocations) the call site
of the recursive cmd_status was forgotten. At that place orig_args is
still passed into the recursion, which is always empty since then. This
did not break anything because the orig_flags logic is not needed at all
when a function from the submodule script is called with eval, as that
inherits all the variables set by the option parsing done in the first
level of the recursion.

Now that we know that orig_flags and orig_args aren't needed at all,
let's just remove them from cmd_status().

58ca9ad4d6 t7407: Fix recursive submodule test
A test in t7404-submodule-foreach purports to test that
the --cached flag is properly noticed by --recursive calls
to the foreach command as it descends into nested
submodules.  However, the test really does not perform this
test since the change it looks for is in a top-level
submodule handled by the first invocation of the command.
To properly test for the flag being passed to recursive
invocations, the change must be buried deeper in the
hierarchy.

Move the change one level deeper so it properly verifies
the recursive machinery of the 'git submodule status'
command.

02e8ca0e50 parse_dirstat_params(): use string_list to split comma-separated string
Use string_list_split_in_place() to split the comma-separated
parameters string.  This simplifies the code and also fixes a bug: the
old code made calls like

    memcmp(p, "lines", p_len)

which needn't work if p_len is different than the length of the
constant string (and could illegally access memory if p_len is larger
than the length of the constant string).

When p_len was less than the length of the constant string, the old
code would have allowed some abbreviations to be accepted (e.g., "cha"
for "changes") but this seems to have been a bug rather than a
feature, because (1) it is not documented; (2) no attempt was made to
handle ambiguous abbreviations, like "c" for "changes" vs
"cumulative".

This function was added in f103f95b11 in
the erroneous expectation that it would be used in the
reimplementation of longest_ancestor_length().  But it turned out to
be easier to use a function specialized for comparing path prefixes
(i.e., one that knows about slashes and root paths) than to prepare
the paths in such a way that a generic string prefix comparison
function can be used.  So delete string_list_longest_prefix() and its

1b77d83cab setup_git_directory_gently_1(): resolve symlinks in ceiling paths
longest_ancestor_length() relies on a textual comparison of directory
parts to find the part of path that overlaps with one of the paths in
prefix_list.  But this doesn't work if any of the prefixes involves a
symbolic link, because the directories will look different even though
they might logically refer to the same directory.  So canonicalize the
paths listed in GIT_CEILING_DIRECTORIES using real_path_if_valid()
before passing them to longest_ancestor_length().  (Also rename
normalize_ceiling_entry() to canonicalize_ceiling_entry() to reflect
the change.)

path is already in canonical form, so doesn't need to be canonicalized
again.

This fixes some problems with using GIT_CEILING_DIRECTORIES that
contains paths involving symlinks, including t4035 if run with --root
set to a path involving symlinks.

Please note that test t0060 is *not* changed analogously, because that
would make the test suite results dependent on the contents of the
local root directory.  However, real_path() is already tested
independently, and the "ancestor" tests cover the non-normalization
aspects of longest_ancestor_length(), so coverage remains sufficient.

9e2326c7e1 longest_ancestor_length(): require prefix list entries to be normalized
Move the responsibility for normalizing prefixes from
longest_ancestor_length() to its callers. Use slightly different
normalizations at the two callers:

In setup_git_directory_gently_1(), use the old normalization, which
ignores paths that are not usable.  In the next commit we will change
this caller to also resolve symlinks in the paths from
GIT_CEILING_DIRECTORIES as part of the normalization.

In "test-path-utils longest_ancestor_length", use the old
normalization, but die() if any paths are unusable.  Also change t0060
to only pass normalized paths to the test program (no empty entries or
non-absolute paths, strip trailing slashes from the paths, and remove
tests that thereby become redundant).

The point of this change is to reduce the scope of the ancestor_length
tests in t0060 from testing normalization+longest_prefix to testing
only mostly longest_prefix.  This is necessary because when
setup_git_directory_gently_1() starts resolving symlinks as part of
its normalization, it will not be reasonable to do the same in the
test suite, because that would make the test results depend on the
contents of the root directory of the filesystem on which the test is
run.  HOWEVER: under Windows, bash mangles arguments that look like
absolute POSIX paths into DOS paths.  So we have to retain the level
of normalization done by normalize_path_copy() to convert the
bash-mangled DOS paths (which contain backslashes) into paths that use
forward slashes.

ef90ab66e8 pickaxe: use textconv for -S counting
We currently just look at raw blob data when using "-S" to
pickaxe. This is mostly historical, as pickaxe predates the
textconv feature. If the user has bothered to define a
textconv filter, it is more likely that their search string will be
on the textconv output, as that is what they will see in the
diff (and we do not even provide a mechanism for them to
search for binary needles that contain NUL characters).

This patch teaches "-S" to use textconv, just as we

e895589883 git-config: use git_config_with_options
The git-config command has always implemented its own file
lookup and parsing order. This was necessary because its
duplicate-entry handling did not match the way git's
internal callbacks worked. Now that this is no longer the
case, we are free to reuse the existing parsing code.

This saves us a few lines of code, but most importantly, it
means that the logic for which files are examined is
contained only in one place and cannot diverge.

00b347d3aa git-config: do not complain about duplicate entries
If git-config is asked for a single value, it will complain
and exit with an error if it finds multiple instances of
that value. This is unlike the usual internal config
parsing, however, which will generally overwrite previous
values, leaving only the final one. For example:

  [set a multivar]
  $ git config user.email one@example.com
  $ git config --add user.email two@example.com

  [use the internal parser to fetch it]
  $ git var GIT_AUTHOR_IDENT
  Your Name <two@example.com> ...

  [use git-config to fetch it]
  $ git config user.email
  one@example.com
  error: More than one value for the key user.email: two@example.com

This overwriting behavior is critical for the regular
parser, which starts with the lowest-priority file (e.g.,
/etc/gitconfig) and proceeds to the highest-priority file
($GIT_DIR/config). Overwriting yields the highest priority
value at the end.

Git-config solves this problem by implementing its own
parsing. It goes from highest to lowest priorty, but does
not proceed to the next file if it has seen a value.

So in practice, this distinction never mattered much,
because it only triggered for values in the same file. And
there was not much point in doing that; the real value is in
overwriting values from lower-priority files.

However, this changed with the implementation of config
include files. Now we might see an include overriding a
value from the parent file, which is a sensible thing to do,
but git-config will flag as a duplication.

This patch drops the duplicate detection for git-config and
switches to a pure-overwrite model (for the single case;
--get-all can still be used if callers want to do something
more fancy).

As is shown by the modifications to the test suite, this is
a user-visible change in behavior. An alternative would be
to just change the include case, but this is much cleaner
for a few reasons:

  1. If you change the include case, then to what? If you
     just stop parsing includes after getting a value, then
     you will get a _different_ answer than the regular
     config parser (you'll get the first value instead of
     the last value). So you'd want to implement overwrite
     semantics anyway.

  2. Even though it is a change in behavior for git-config,
     it is bringing us in line with what the internal
     parsers already do.

  3. The file-order reimplementation is the only thing
     keeping us from sharing more code with the internal
     config parser, which will help keep differences to a
     minimum.

Going under the assumption that the primary purpose of
git-config is to behave identically to how git's internal
parsing works, this change can be seen as a bug-fix.

It does mean we're no longer streaming, and we're storing

ed838e6615 t1300: style updates
The t1300 test script is quite old, and does not use our
modern techniques or styles. This patch updates it in the
following ways:

  1. Use test_cmp instead of cmp (to make failures easier to
     debug).

  2. Use test_cmp instead of 'test $(command) = expected'.
     This makes failures much easier to debug, and also
     makes sure that $(command) exits appropriately.

  3. Use test_must_fail (easier to read, and checks more
     rigorously for signal death).

  4. Write tests with the usual style of:

       test_expect_success 'test name' '
               test commands &&
	       ...
       '

     rather than one-liners, or using backslash-continuation.
     This is purely a style fixup.

There are still a few command happening outside of
test_expect invocations, but they are all innoccuous system
commands like "cat" and "cp". In an ideal world, each test
would be self sufficient and all commands would happen
inside test_expect, but it is not immediately obvious how
the grouping should work (some of the commands impact the
subsequent tests, and some of them are setting up and
modifying state that many tests depend on). This patch just
picks the low-hanging style fruit, and we can do more fixes
on top later.

3c730fab2c filter-branch: use git-sh-setup's ident parsing functions

It also avoids using "tr", which has had some odd

We also tweak one of the tests in t7003 to double-check that

f3f47a1e8d status: add --long output format option
You can currently set the output format to --short or
--porcelain. There is no --long, because we default to it
already. However, you may want to override an alias that
uses "--short" to get back to the default.

This requires a little bit of refactoring, because currently
we use STATUS_FORMAT_LONG internally to mean the same as
"the user did not specify anything". By expanding the enum
to include STATUS_FORMAT_NONE, we can distinguish between
the implicit and explicit cases. This effects these
conditions:

  1. The user has asked for NUL termination. With NONE, we
     currently default to turning on the porcelain mode.
     With an explicit --long, we would in theory use NUL
     termination with the long mode, but it does not support
     it. So we can just complain and die.

  2. When an output format is given to "git commit", we
     default to "--dry-run". This behavior would now kick in
     when "--long" is given, too.

08ad56f3f0 strbuf: always return a non-NULL value from strbuf_detach
The current behavior is to return NULL when strbuf did not
actually allocate a string. This can be quite surprising to
callers, though, who may feed the strbuf from arbitrary data
and expect to always get a valid value.

In most cases, it does not make a difference because calling
any strbuf function will cause an allocation (even if the
function ends up not inserting any data). But if the code is
structured like:

  struct strbuf buf = STRBUF_INIT;
  if (some_condition)
	  strbuf_addstr(&buf, some_string);
  return strbuf_detach(&buf, NULL);

then you may or may not return NULL, depending on the
condition. This can cause us to segfault in http-push
(when fed an empty URL) and in http-backend (when an empty
parameter like "foo=bar&&" is in the $QUERY_STRING).

This patch forces strbuf_detach to allocate an empty
NUL-terminated string when it is called on a strbuf that has
not been allocated.

I investigated all call-sites of strbuf_detach. The majority
are either not affected by the change (because they call a
strbuf_* function unconditionally), or can handle the empty
string just as easily as NULL.

74faaa16f0 Fix "git diff --stat" for interesting - but empty - file changes
The behavior of "git diff --stat" is rather odd for files that have
zero lines of changes: it will discount them entirely unless they were
renames.

Which means that the stat output will simply not show files that only
had "other" changes: they were created or deleted, or their mode was
changed.

Now, those changes do show up in the summary, but so do renames, so
the diffstat logic is inconsistent. Why does it show renames with zero
lines changed, but not mode changes or added files with zero lines
changed?

So change the logic to not check for "is_renamed", but for
"is_interesting" instead, where "interesting" is judged to be any
action but a pure data change (because a pure data change with zero
data changed really isn't worth showing, if we ever get one in our
diffpairs).

So if you did

   chmod +x Makefile
   git diff --stat

before, it would show empty (" 0 files changed"), with this it shows

 Makefile | 0
 1 file changed, 0 insertions(+), 0 deletions(-)

which I think is a more correct diffstat (and then with "--summary" it
shows *what* the metadata change to Makefile was - this is completely
consistent with our handling of renamed files).

Side note: the old behavior was *really* odd. With no changes at all,
"git diff --stat" output was empty. With just a chmod, it said "0
files changed". No way is our legacy behavior sane.

82dce998c2 attr: more matching optimizations from .gitignore
.gitattributes and .gitignore share the same pattern syntax but has
separate matching implementation. Over the years, ignore's
implementation accumulates more optimizations while attr's stays the
same.

This patch reuses the core matching functions that are also used by
excluded_from_list. excluded_from_list and path_matches can't be
merged due to differences in exclude and attr, for example:

* "!pattern" syntax is forbidden in .gitattributes.  As an attribute
  can be unset (i.e. set to a special value "false") or made back to
  unspecified (i.e. not even set to "false"), "!pattern attr" is unclear
  which one it means.

* we support attaching attributes to directories, but git-core
  internally does not currently make use of attributes on
  directories.

8f2bbe452e config: exit on error accessing any config file
There is convenience in warning and moving on when somebody has a
bogus permissions on /etc/gitconfig and cannot do anything about it.
But the cost in predictability and security is too high --- when
unreadable config files are skipped, it means an I/O error or
permissions problem causes important configuration to be bypassed.

For example, servers may depend on /etc/gitconfig to enforce security
policy (setting transfer.fsckObjects or receive.deny*).  Best to
always error out when encountering trouble accessing a config file.

This may add inconvenience in some cases:

  1. You are inspecting somebody else's repo, and you do not have
     access to their .git/config file.  Git typically dies in this
     case already since we cannot read core.repositoryFormatVersion,
     so the change should not be too noticeable.

  2. You have used "sudo -u" or a similar tool to switch uid, and your
     environment still points Git at your original user's global
     config, which is not readable.  In this case people really would
     be inconvenienced (they would rather see the harmless warning and
     continue the operation) but they can work around it by setting
     HOME appropriately after switching uids.

  3. You do not have access to /etc/gitconfig due to a broken setup.
     In this case, erroring out is a good way to put pressure on the
     sysadmin to fix the setup.  While they wait for a reply, users
     can set GIT_CONFIG_NOSYSTEM to true to keep Git working without
     complaint.

After this patch, errors accessing the repository-local and systemwide
config files and files requested in include directives cause Git to
exit, just like errors accessing ~/.gitconfig.

96b9e0e313 config: treat user and xdg config permission problems as errors
Git reads multiple configuration files: settings come first from the
system config file (typically /etc/gitconfig), then the xdg config
file (typically ~/.config/git/config), then the user's dotfile
(~/.gitconfig), then the repository configuration (.git/config).

Git has always used access(2) to decide whether to use each file; as
an unfortunate side effect, that means that if one of these files is
unreadable (e.g., EPERM or EIO), git skips it.  So if I use
~/.gitconfig to override some settings but make a mistake and give it
the wrong permissions then I am subject to the settings the sysadmin
chose for /etc/gitconfig.

Better to error out and ask the user to correct the problem.

This only affects the user and xdg config files, since the user
presumably has enough access to fix their permissions.  If the system
config file is unreadable, the best we can do is to warn about it so
the user knows to notify someone and get on with work in the meantime.

e5c52c9898 config, gitignore: failure to access with ENOTDIR is ok
The access_or_warn() function is used to check for optional
configuration files like .gitconfig and .gitignore and warn when they
are not accessible due to a configuration issue (e.g., bad
permissions).  It is not supposed to complain when a file is simply
missing.

Noticed on a system where ~/.config/git was a file --- when the new
XDG_CONFIG_HOME support looks for ~/.config/git/config it should
ignore ~/.config/git instead of printing irritating warnings:

 $ git status -s
 warning: unable to access '/home/jrn/.config/git/config': Not a directory

5de7166d46 apply.c:update_pre_post_images(): the preimage can be truncated
5166714 (apply: Allow blank context lines to match beyond EOF,
2010-03-06) and then later 0c3ef98 (apply: Allow blank *trailing*
context lines to match beyond EOF, 2010-04-08) taught "git apply"
to trim new blank lines at the end in the patch text when matching
the contents being patched and the preimage recorded in the patch,
under --whitespace=fix mode.

When a preimage is modified to match the current contents in
preparation for such a "fixed" patch application, the context lines
in the postimage must be updated to match (otherwise, it would
reintroduce whitespace breakages), and update_pre_post_images()
function is responsible for doing this.  However, this function was
not updated to take into account a case where the removal of
trailing blank lines reduces the number of lines in the preimage,
and triggered an assertion error.

The logic to fix the postimage by copying the corrected context
lines from the preimage was not prepared to handle this case,
either, but it was protected by the assert() and only got exposed
when the assertion is corrected.

1960897ebc http: do not set up curl auth after a 401
When we get an http 401, we prompt for credentials and put
them in our global credential struct. We also feed them to
the curl handle that produced the 401, with the intent that
they will be used on a retry.

When the code was originally introduced in commit 42653c0,
this was a necessary step. However, since dfa1725, we always
feed our global credential into every curl handle when we
initialize the slot with get_active_slot. So every further
request already feeds the credential to curl.

Moreover, accessing the slot here is somewhat dubious. After
the slot has produced a response, we don't actually control
it any more.  If we are using curl_multi, it may even have
been re-initialized to handle a different request.

It just so happens that we will reuse the curl handle within
the slot in such a case, and that because we only keep one
global credential, it will be the one we want.  So the
current code is not buggy, but it is misleading.

By cleaning it up, we can remove the slot argument entirely
from handle_curl_result, making it much more obvious that
slots should not be accessed after they are marked as
finished.

abf8df869c remote-curl: do not call run_slot repeatedly
Commit b81401c (http: prompt for credentials on failed POST)
taught post_rpc to call run_slot in a loop in order to retry
a request after asking the user for credentials. However,
after a call to run_slot we will have called
finish_active_slot. This means we have released the slot,
and we should no longer look at it.

As it happens, this does not cause any bugs in the current
code, since we know that we are not using curl_multi in this
code path, and therefore nobody will have taken over our
slot in the meantime. However, it is good form to actually
call get_active_slot again. It also future proofs us against
changes in the http code.

We can do this by jumping back to a retry label at the top
of our function. We just need to reorder a few setup lines
that should not be repeated; everything else within the loop
is either idempotent, needs to be repeated, or in a path we
do not follow (e.g., we do not even try when large_request
is set, because we don't know how much data we might have
streamed from our helper program).

To ease testing without depending on a reachable svn server, this
compact python script mimics parts of svnrdumps behaviour.  It
requires the remote url to start with sim://.

Start and end revisions are evaluated.  If the requested revision
doesn't exist, as it is the case with incremental imports, if no new
commit was added, it returns 1 (like svnrdump).

To allow using the same dump file for simulating multiple incremental
imports, the highest revision can be limited by setting the environment
variable SVNRMAX to that value. This simulates the situation where
higher revs don't exist yet.

remote-helpers to retrieve information about blobs and trees that
already exist in fast-import's memory. This requires a channel from
fast-import to the remote-helper.

remote-helpers that use these features shall advertise the new
'bidi-import' capability to signal that they require the communication
channel.  When forking fast-import in transport-helper.c connect it to
a dup of the remote-helper's stdin-pipe. The additional file
descriptor is passed to fast-import via its command line
(--cat-blob-fd).  It follows that git and fast-import are connected to
the remote-helpers's stdin.

Because git can send multiple commands to the remote-helper on it's
stdin, it is required that helpers that advertise 'bidi-import' buffer
all input commands until the batch of 'import' commands is ended by a
newline before sending data to fast-import.  This is to prevent mixing
commands and fast-import responses on the helper's stdin.

68f64ff8b4 Implement a remote helper for svn in C
Enable basic fetching from subversion repositories. When processing
remote URLs starting with testsvn::, git invokes this remote-helper.
It starts svnrdump to extract revisions from the subversion repository
in the 'dump file format', and converts them to a git-fast-import stream
using the functions of vcs-svn/.

Imported refs are created in a private namespace at
refs/svn/<remote-name>/master.  The revision history is imported
linearly (no branch detection) and completely, i.e. from revision 0 to
HEAD.

The 'bidi-import' capability is used. The remote-helper expects data
from fast-import on its stdin. It buffers a batch of 'import' command
lines in a string_list before starting to process them.

435c833237 upload-pack: use peel_ref for ref advertisements
When upload-pack advertises refs, we attempt to peel tags
and advertise the peeled version. We currently hand-roll the
tag dereferencing, and use as many optimizations as we can
to avoid loading non-tag objects into memory.

Not only has peel_ref recently learned these optimizations,
too, but it also contains an even more important one: it
has access to the "peeled" data from the pack-refs file.
That means we can avoid not only loading annotated tags
entirely, but also avoid doing any kind of object lookup at
all.

This cut the CPU time to advertise refs by 50% in the
linux-2.6 repo, as measured by:

  echo 0000 | git-upload-pack . >/dev/null

best-of-five, warm cache, objects and refs fully packed:

  [before]             [after]
  real    0m0.026s     real    0m0.013s
  user    0m0.024s     user    0m0.008s
  sys     0m0.000s     sys     0m0.000s

Those numbers are irrelevantly small compared to an actual
fetch. Here's a larger repo (400K refs, of which 12K are
unique, and of which only 107 are unique annotated tags):

  [before]             [after]
  real    0m0.704s     real    0m0.596s
  user    0m0.600s     user    0m0.496s
  sys     0m0.096s     sys     0m0.092s

This shows only a 15% speedup (mostly because it has fewer
actual tags to parse), but a larger absolute value (100ms,
which isn't a lot compared to a real fetch, but this
advertisement happens on every fetch, even if the client is
just finding out they are completely up to date).

In truly pathological cases, where you have a large number
of unique annotated tags, it can make an even bigger
difference. Here are the numbers for a linux-2.6 repository
that has had every seventh commit tagged (so about 50K
tags):

  [before]             [after]
  real    0m0.443s     real    0m0.097s
  user    0m0.416s     user    0m0.080s
  sys     0m0.024s     sys     0m0.012s

6c4a060d7d peel_ref: check object type before loading
The point of peel_ref is to dereference tags; if the base
object is not a tag, then we can return early without even
loading the object into memory.

This patch accomplishes that by checking sha1_object_info
for the type. For a packed object, we can get away with just
looking in the pack index. For a loose object, we only need
to inflate the first couple of header bytes.

This is a bit of a gamble; if we do find a tag object, then
we will end up loading the content anyway, and the extra
lookup will have been wasteful. However, if it is not a tag
object, then we save loading the object entirely. Depending
on the ratio of non-tags to tags in the input, this can be a
minor win or minor loss.

However, it does give us one potential major win: if a ref
points to a large blob (e.g., via an unannotated tag), then
we can avoid looking at it entirely.

e6dbffa67b peel_ref: do not return a null sha1
The idea of the peel_ref function is to dereference tag
objects recursively until we hit a non-tag, and return the
sha1. Conceptually, it should return 0 if it is successful
(and fill in the sha1), or -1 if there was nothing to peel.

However, the current behavior is much more confusing. For a
regular loose ref, the behavior is as described above. But
there is an optimization to reuse the peeled-ref value for a
ref that came from a packed-refs file. If we have such a
ref, we return its peeled value, even if that peeled value
is null (indicating that we know the ref definitely does
_not_ peel).

It might seem like such information is useful to the caller,
who would then know not to bother loading and trying to peel
the object. Except that they should not bother loading and
trying to peel the object _anyway_, because that fallback is
already handled by peel_ref. In other words, the whole point
of calling this function is that it handles those details
internally, and you either get a sha1, or you know that it
is not peel-able.

This patch catches the null sha1 case internally and
converts it into a -1 return value (i.e., there is nothing
to peel). This simplifies callers, which do not need to
bother checking themselves.

Two callers are worth noting:

  - in pack-objects, a comment indicates that there is a
    difference between non-peelable tags and unannotated
    tags. But that is not the case (before or after this
    patch). Whether you get a null sha1 has to do with
    internal details of how peel_ref operated.

  - in show-ref, if peel_ref returns a failure, the caller
    tries to decide whether to try peeling manually based on
    whether the REF_ISPACKED flag is set. But this doesn't
    make any sense. If the flag is set, that does not
    necessarily mean the ref came from a packed-refs file
    with the "peeled" extension. But it doesn't matter,
    because even if it didn't, there's no point in trying to
    peel it ourselves, as peel_ref would already have done
    so. In other words, the fallback peeling is guaranteed
    to fail.

44da6f69ec peel_ref: use faster deref_tag_noverify
When we are asked to peel a ref to a sha1, we internally call
deref_tag, which will recursively parse each tagged object
until we reach a non-tag. This has the benefit that we will
verify our ability to load and parse the pointed-to object.

However, there is a performance downside: we may not need to
load that object at all (e.g., if we are listing peeled
simply listing peeled refs), or it may be a large object
that should follow a streaming code path (e.g., an annotated
tag of a large blob).

It makes more sense for peel_ref to choose the fast thing
rather than performing the extra check, for two reasons:

  1. We will already sometimes short-circuit the tag parsing
     in favor of a peeled entry from a packed-refs file. So
     we are already favoring speed in some cases, and it is
     not wise for a caller to rely on peel_ref to detect
     corruption.

  2. We already silently ignore much larger corruptions,
     like a ref that points to a non-existent object, or a
     tag object that exists but is corrupted.

  2. peel_ref is not the right place to check for such a
     database corruption. It is returning only the sha1
     anyway, not the actual object. Any callers which use
     that sha1 to load an object will soon discover the
     corruption anyway, so we are really just pushing back
     the discovery to later in the program.

The 'a', 'i' and 'c' commands take a literal text to be added
followed by backslash, but then in the source we cannot indent

We need to also remember to double the backslash inside double

4b7c286ec7 submodule add: Fail when .git/modules/<name> already exists unless forced
When adding a new submodule it can happen that .git/modules/<name> already
contains a submodule repo, e.g. when a submodule is removed from the work
tree and another submodule is added at the same path. But then the work
tree of the submodule will be populated using the existing repository and
not the one the user provided, which results in an incorrect work tree. On
the other hand the user might reactivate a submodule removed earlier, then
reusing that .git directory is the Right Thing to do.

As git can't decide what is the case, error out and tell the user she
should use either use a different name for the submodule with the "--name"
option or can reuse the .git directory for the newly added submodule by
providing the --force option (which only makes sense when the upstream
matches, so the error message lists all remotes of .git/modules/<name>).

In one test in t7406 the --force option had to be added to "git submodule
add", as that test re-adds a formerly removed submodule.

73b0898d0d Teach "git submodule add" the --name option
"git submodule add" initializes the name of a submodule to its path. This
was ok as long as the .git directory lived inside the submodule's work
tree, but since 1.7.8 it is stored in the .git/modules/<name> directory of
the superproject, making the submodule name survive the removal of the
submodule's work tree. This leads to problems when the user tries to add a
different submodule at the same path - and thus the same name - later, as
that will happily try to restore the submodule from the old repository
instead of the one the user specified and will lead to a checkout of the
wrong repository.

Add the new "--name" option to let the user provide a name for the
submodule. This enables the user to solve this conflict without having to
remove .git/modules/<name> by hand (which is no viable solution as it
makes it impossible to checkout a commit that records the old submodule
and populate it, as that will still check out the new submodule for the
same reason).

To achieve that the submodule's name is added to the parameter list of
the module_clone() helper function. This makes it possible to remove the
call of module_name() there because both callers of module_clone() already
know the name and can provide it as argument number two.

293ab15eea submodule: teach rm to remove submodules unless they contain a git directory
Currently using "git rm" on a submodule - populated or not - fails with
this error:

	fatal: git rm: '<submodule path>': Is a directory

This made sense in the past as there was no way to remove a submodule
without possibly removing unpushed parts of the submodule's history
contained in its .git directory too, so erroring out here protected the
user from possible loss of data.

But submodules cloned with a recent git version do not contain the .git
directory anymore, they use a gitfile to point to their git directory
which is safely stored inside the superproject's .git directory. The work
tree of these submodules can safely be removed without losing history, so
let's teach git to do so.

Using rm on an unpopulated submodule now removes the empty directory from
the work tree and the gitlink from the index. If the submodule's directory
is missing from the work tree, it will still be removed from the index.

Using rm on a populated submodule using a gitfile will apply the usual
checks for work tree modification adapted to submodules (unless forced).
For a submodule that means that the HEAD is the same as recorded in the
index, no tracked files are modified and no untracked files that aren't
ignored are present in the submodules work tree (ignored files are deemed
expendable and won't stop a submodule's work tree from being removed).
That logic has to be applied in all nested submodules too.

Using rm on a submodule which has its .git directory inside the work trees
top level directory will just error out like it did before to protect the
repository, even when forced. In the future git could either provide a
message informing the user to convert the submodule to use a gitfile or
even attempt to do the conversion itself, but that is not part of this
change.

e8320f350f pager: drop "wait for output to run less" hack
Commit 35ce862 (pager: Work around window resizing bug in
'less', 2007-01-24) causes git's pager sub-process to wait
to receive input after forking but before exec-ing the
pager. To handle this, run-command had to grow a "pre-exec
callback" feature. Unfortunately, this feature does not work
at all on Windows (where we do not fork), and interacts
poorly with run-command's parent notification system. Its
use should be discouraged.

The bug in less was fixed in version 406, which was released
in June 2007. It is probably safe at this point to remove
our workaround. That lets us rip out the preexec_cb feature
entirely.

Git v1.8.0.2 Release Notes
==========================
Fixes since v1.8.0.1
--------------------
* Various codepaths have workaround for a common misconfiguration to
spell "UTF-8" as "utf8", but it was not used uniformly. Most
notably, mailinfo (which is used by "git am") lacked this support.
* We failed to mention a file without any content change but whose
permission bit was modified, or (worse yet) a new file without any
content in the "git diff --stat" output.
* When "--stat-count" hides a diffstat for binary contents, the total
number of added and removed lines at the bottom was computed
incorrectly.
* When "--stat-count" hides a diffstat for unmerged paths, the total
number of affected files at the bottom of the "diff --stat" output
was computed incorrectly.
* "diff --shortstat" miscounted the total number of affected files
when there were unmerged paths.
* "git p4" used to try expanding malformed "$keyword$" that spans
across multiple lines.
* "git update-ref -d --deref SYM" to delete a ref through a symbolic
ref that points to it did not remove it correctly.
* Syntax highlighting in "gitweb" was not quite working.
Also contains other minor fixes and documentation updates.

Git 1.8.1.1 Release Notes
=========================
Fixes since v1.8.1
------------------
* The attribute mechanism didn't allow limiting attributes to be
applied to only a single directory itself with "path/" like the
exclude mechanism does.
* When attempting to read the XDG-style $HOME/.config/git/config and
finding that $HOME/.config/git is a file, we gave a wrong error
message, instead of treating the case as "a custom config file does
not exist there" and moving on.
* After failing to create a temporary file using mkstemp(), failing
pathname was not reported correctly on some platforms.
* http transport was wrong to ask for the username when the
authentication is done by certificate identity.
* The behaviour visible to the end users was confusing, when they
attempt to kill a process spawned in the editor that was in turn
launched by Git with SIGINT (or SIGQUIT), as Git would catch that
signal and die. We ignore these signals now.
* A child process that was killed by a signal (e.g. SIGINT) was
reported in an inconsistent way depending on how the process was
spawned by us, with or without a shell in between.
* After "git add -N" and then writing a tree object out of the
index, the cache-tree data structure got corrupted.
* "git apply" misbehaved when fixing whitespace breakages by removing
excess trailing blank lines in some corner cases.
* A tar archive created by "git archive" recorded a directory in a
way that made NetBSD's implementation of "tar" sometimes unhappy.
* When "git clone --separate-git-dir=$over_there" is interrupted, it
failed to remove the real location of the $GIT_DIR it created.
This was most visible when interrupting a submodule update.
* "git fetch --mirror" and fetch that uses other forms of refspec
with wildcard used to attempt to update a symbolic ref that match
the wildcard on the receiving end, which made little sense (the
real ref that is pointed at by the symbolic ref would be updated
anyway). Symbolic refs no longer are affected by such a fetch.
* The "log --graph" codepath fell into infinite loop in some
corner cases.
* "git merge" started calling prepare-commit-msg hook like "git
commit" does some time ago, but forgot to pay attention to the exit
status of the hook.
* "git pack-refs" that ran in parallel to another process that
created new refs had a race that can lose new ones.
* When a line to be wrapped has a solid run of non space characters
whose length exactly is the wrap width, "git shortlog -w" failed
to add a newline after such a line.
* The way "git svn" asked for password using SSH_ASKPASS and
GIT_ASKPASS was not in line with the rest of the system.
* "gitweb", when sorting by age to show repositories with new
activities first, used to sort repositories with absolutely
nothing in it early, which was not very useful.
* "gitweb", when sorting by age to show repositories with new
activities first, used to sort repositories with absolutely
nothing in it early, which was not very useful.
* When autoconf is used, any build on a different commit always ran
"config.status --recheck" even when unnecessary.
* Some scripted programs written in Python did not get updated when
PYTHON_PATH changed.
* We have been carrying a translated and long-unmaintained copy of an
old version of the tutorial; removed.
* Portability issues in many self-test scripts have been addressed.

Git 1.8.1.2 Release Notes
=========================
Fixes since v1.8.1.1
--------------------
* An element on GIT_CEILING_DIRECTORIES list that does not name the
real path to a directory (i.e. a symbolic link) could have caused
the GIT_DIR discovery logic to escape the ceiling.
* Command line completion for "tcsh" emitted an unwanted space
after completing a single directory name.
* Command line completion leaked an unnecessary error message while
looking for possible matches with paths in <tree-ish>.
* "git archive" did not record uncompressed size in the header when
streaming a zip archive, which confused some implementations of unzip.
* When users spelled "cc:" in lowercase in the fake "header" in the
trailer part, "git send-email" failed to pick up the addresses from
there. As e-mail headers field names are case insensitive, this
script should follow suit and treat "cc:" and "Cc:" the same way.
Also contains various documentation fixes.

Git 1.8.1.3 Release Notes
=========================
Fixes since v1.8.1.2
--------------------
* The attribute mechanism didn't allow limiting attributes to be
applied to only a single directory itself with "path/" like the
exclude mechanism does. The fix for this in 1.8.1.2 had
performance degradations.
* Command line completion code was inadvertently made incompatible with
older versions of bash by using a newer array notation.
* Scripts to test bash completion was inherently flaky as it was
affected by whatever random things the user may have on $PATH.
* A fix was added to the build procedure to work around buggy
versions of ccache broke the auto-generation of dependencies, which
unfortunately is still relevant because some people use ancient
distros.
* We used to stuff "user@" and then append what we read from
/etc/mailname to come up with a default e-mail ident, but a bug
lost the "user@" part.
* "git am" did not parse datestamp correctly from Hg generated patch,
when it is run in a locale outside C (or en).
* Attempt to "branch --edit-description" an existing branch, while
being on a detached HEAD, errored out.
* "git cherry-pick" did not replay a root commit to an unborn branch.
* We forgot to close the file descriptor reading from "gpg" output,
killing "git log --show-signature" on a long history.
* "git rebase --preserve-merges" lost empty merges in recent versions
of Git.
* Rebasing the history of superproject with change in the submodule
has been broken since v1.7.12.
* A failure to push due to non-ff while on an unborn branch
dereferenced a NULL pointer when showing an error message.

Git v1.8.1 Release Notes
========================
Backward compatibility notes
----------------------------
In the next major release (not *this* one), we will change the
behavior of the "git push" command.
When "git push [$there]" does not say what to push, we have used the
traditional "matching" semantics so far (all your branches were sent
to the remote as long as there already are branches of the same name
over there). We will use the "simple" semantics that pushes the
current branch to the branch with the same name, only when the current
branch is set to integrate with that remote branch. There is a user
preference configuration variable "push.default" to change this, and
"git push" will warn about the upcoming change until you set this
variable in this release.
"git branch --set-upstream" is deprecated and may be removed in a
relatively distant future. "git branch [-u|--set-upstream-to]" has
been introduced with a saner order of arguments to replace it.
Updates since v1.8.0
--------------------
UI, Workflows & Features
* Command-line completion scripts for tcsh and zsh have been added.
* "git-prompt" scriptlet (in contrib/completion) can be told to paint
pieces of the hints in the prompt string in colors.
* Some documentation pages that used to ship only in the plain text
format are now formatted in HTML as well.
* We used to have a workaround for a bug in ancient "less" that
causes it to exit without any output when the terminal is resized.
The bug has been fixed in "less" version 406 (June 2007), and the
workaround has been removed in this release.
* When "git checkout" checks out a branch, it tells the user how far
behind (or ahead) the new branch is relative to the remote tracking
branch it builds upon. The message now also advises how to sync
them up by pushing or pulling. This can be disabled with the
advice.statusHints configuration variable.
* "git config --get" used to diagnose presence of multiple
definitions of the same variable in the same configuration file as
an error, but it now applies the "last one wins" rule used by the
internal configuration logic. Strictly speaking, this may be an
API regression but it is expected that nobody will notice it in
practice.
* A new configuration variable "diff.context" can be used to
give the default number of context lines in the patch output, to
override the hardcoded default of 3 lines.
* "git format-patch" learned the "--notes=<ref>" option to give
notes for the commit after the three-dash lines in its output.
* "git log -p -S<string>" now looks for the <string> after applying
the textconv filter (if defined); earlier it inspected the contents
of the blobs without filtering.
* "git log --grep=<pcre>" learned to honor the "grep.patterntype"
configuration set to "perl".
* "git replace -d <object>" now interprets <object> as an extended
SHA-1 (e.g. HEAD~4 is allowed), instead of only accepting full hex
object name.
* "git rm $submodule" used to punt on removing a submodule working
tree to avoid losing the repository embedded in it. Because
recent git uses a mechanism to separate the submodule repository
from the submodule working tree, "git rm" learned to detect this
case and removes the submodule working tree when it is safe to do so.
* "git send-email" used to prompt for the sender address, even when
the committer identity is well specified (e.g. via user.name and
user.email configuration variables). The command no longer gives
this prompt when not necessary.
* "git send-email" did not allow non-address garbage strings to
appear after addresses on Cc: lines in the patch files (and when
told to pick them up to find more recipients), e.g.
Cc: Stable Kernel <stable@k.org> # for v3.2 and up
The command now strips " # for v3.2 and up" part before adding the
remainder of this line to the list of recipients.
* "git submodule add" learned to add a new submodule at the same
path as the path where an unrelated submodule was bound to in an
existing revision via the "--name" option.
* "git submodule sync" learned the "--recursive" option.
* "diff.submodule" configuration variable can be used to give custom
default value to the "git diff --submodule" option.
* "git symbolic-ref" learned the "-d $symref" option to delete the
named symbolic ref, which is more intuitive way to spell it than
"update-ref -d --no-deref $symref".
Foreign Interface
* "git cvsimport" can be told to record timezones (other than GMT)
per-author via its author info file.
* The remote helper interface to interact with subversion
repositories (one of the GSoC 2012 projects) has been merged.
* A new remote-helper interface for Mercurial has been added to
contrib/remote-helpers.
* The documentation for git(1) was pointing at a page at an external
site for the list of authors that no longer existed. The link has
been updated to point at an alternative site.
Performance, Internal Implementation, etc.
* Compilation on Cygwin with newer header files are supported now.
* A couple of low-level implementation updates on MinGW.
* The logic to generate the initial advertisement from "upload-pack"
(i.e. what is invoked by "git fetch" on the other side of the
connection) to list what refs are available in the repository has
been optimized.
* The logic to find set of attributes that match a given path has
been optimized.
* Use preloadindex in "git diff-index" and "git update-index", which
has a nice speedup on systems with slow stat calls (and even on
Linux).
Also contains minor documentation updates and code clean-ups.
Fixes since v1.8.0
------------------
Unless otherwise noted, all the fixes since v1.8.0 in the maintenance
track are contained in this release (see release notes to them for
details).
* The configuration parser had an unnecessary hardcoded limit on
variable names that was not checked consistently.
* The "say" function in the test scaffolding incorrectly allowed
"echo" to interpret "\a" as if it were a C-string asking for a
BEL output.
* "git mergetool" feeds /dev/null as a common ancestor when dealing
with an add/add conflict, but p4merge backend cannot handle
it. Work it around by passing a temporary empty file.
* "git log -F -E --grep='<ere>'" failed to use the given <ere>
pattern as extended regular expression, and instead looked for the
string literally.
* "git grep -e pattern <tree>" asked the attribute system to read
"<tree>:.gitattributes" file in the working tree, which was
nonsense.
* A symbolic ref refs/heads/SYM was not correctly removed with "git
branch -d SYM"; the command removed the ref pointed by SYM
instead.
* Update "remote tracking branch" in the documentation to
"remote-tracking branch".
* "git pull --rebase" run while the HEAD is detached tried to find
the upstream branch of the detached HEAD (which by definition
does not exist) and emitted unnecessary error messages.
* The refs/replace hierarchy was not mentioned in the
repository-layout docs.
* Various rfc2047 quoting issues around a non-ASCII name on the
From: line in the output from format-patch have been corrected.
* Sometimes curl_multi_timeout() function suggested a wrong timeout
value when there is no file descriptor to wait on and the http
transport ended up sleeping for minutes in select(2) system call.
A workaround has been added for this.
* For a fetch refspec (or the result of applying wildcard on one),
we always want the RHS to map to something inside "refs/"
hierarchy, but the logic to check it was not exactly right.
(merge 5c08c1f jc/maint-fetch-tighten-refname-check later to maint).
* "git diff -G<pattern>" did not honor textconv filter when looking
for changes.
* Some HTTP servers ask for auth only during the actual packing phase
(not in ls-remote phase); this is not really a recommended
configuration, but the clients used to fail to authenticate with
such servers.
(merge 2e736fd jk/maint-http-half-auth-fetch later to maint).
* "git p4" used to try expanding malformed "$keyword$" that spans
across multiple lines.
* Syntax highlighting in "gitweb" was not quite working.
* RSS feed from "gitweb" had a xss hole in its title output.
* "git config --path $key" segfaulted on "[section] key" (a boolean
"true" spelled without "=", not "[section] key = true").
* "git checkout -b foo" while on an unborn branch did not say
"Switched to a new branch 'foo'" like other cases.
* Various codepaths have workaround for a common misconfiguration to
spell "UTF-8" as "utf8", but it was not used uniformly. Most
notably, mailinfo (which is used by "git am") lacked this support.
* We failed to mention a file without any content change but whose
permission bit was modified, or (worse yet) a new file without any
content in the "git diff --stat" output.
* When "--stat-count" hides a diffstat for binary contents, the total
number of added and removed lines at the bottom was computed
incorrectly.
* When "--stat-count" hides a diffstat for unmerged paths, the total
number of affected files at the bottom of the "diff --stat" output
was computed incorrectly.
* "diff --shortstat" miscounted the total number of affected files
when there were unmerged paths.
* "update-ref -d --deref SYM" to delete a ref through a symbolic ref
that points to it did not remove it correctly.

Checklist (and a short version for the impatient):
Commits:
- make commits of logical units
- check for unnecessary whitespace with "git diff --check"
before committing
- do not check in commented out code or unneeded files
- the first line of the commit message should be a short
description (50 characters is the soft limit, see DISCUSSION
in git-commit(1)), and should skip the full stop
- the body should provide a meaningful commit message, which:
. explains the problem the change tries to solve, iow, what
is wrong with the current code without the change.
. justifies the way the change solves the problem, iow, why
the result with the change is better.
. alternate solutions considered but discarded, if any.

instead of "[This patch] makes xyzzy do frotz" or "[I] changed
xyzzy to do frotz", as if you are giving orders to the codebase
to change its behaviour.
- try to make sure your explanation can be understood without
external resources. Instead of giving a URL to a mailing list
archive, summarize the relevant points of the discussion.
- add a "Signed-off-by: Your Name <you@example.com>" line to the
commit message (or just use the option "-s" when committing)
to confirm that you agree to the Developer's Certificate of Origin
- make sure that you have tests for the bug you are fixing
- make sure that the test suite passes after your commit
Patch:
- use "git format-patch -M" to create the patch
- do not PGP sign your patch
- do not attach your patch, but read in the mail
body, unless you cannot teach your mailer to
leave the formatting of the patch alone.
- be careful doing cut & paste into your mailer, not to
corrupt whitespaces.
- provide additional information (which is unsuitable for
the commit message) between the "---" and the diffstat
- if you change, add, or remove a command line option or
make some other user interface change, the associated
documentation should be updated as well.

response to which the remote helper must print a list of the
capabilities it supports (see below) followed by a blank line. The
response to the capabilities command determines what commands Git uses
in the remainder of the command stream.
The command stream is terminated by a blank line. In some cases
(indicated in the documentation of the relevant commands), this blank
line is followed by a payload in some other protocol (e.g., the pack
protocol), while in others it indicates the end of input.

In the following, we list all defined capabilities and for
each we list which commands a helper with that capability
must provide.
Capabilities for Pushing
^^^^^^^^^^^^^^^^^^^^^^^^
'connect'::
Can attempt to connect to 'git receive-pack' (for pushing),

git's native packfile protocol. This
requires a bidirectional, full-duplex connection.

them as a stream in fast-import format.

fall back to another capability if the helper requests so when
connecting (see the 'connect' command under COMMANDS).

Miscellaneous capabilities
^^^^^^^^^^^^^^^^^^^^^^^^^^
'option'::
For specifying settings like `verbosity` (how much output to
write to stderr) and `depth` (how much history is wanted in the
case of a shallow clone) that affect how other commands are
carried out.
'refspec' <refspec>::
This modifies the 'import' capability, allowing the produced
fast-import stream to modify refs in a private namespace
instead of writing to refs/heads or refs/remotes directly.
It is recommended that all importers providing the 'import'
capability use this.
+
A helper advertising the capability
`refspec refs/heads/*:refs/svn/origin/branches/*`
is saying that, when it is asked to `import refs/heads/topic`, the
stream it outputs will update the `refs/svn/origin/branches/topic`
ref.
+
This capability can be advertised multiple times. The first
applicable refspec takes precedence. The left-hand of refspecs
advertised with this capability must cover all refs reported by
the list command. If no 'refspec' capability is advertised,
there is an implied `refspec *:*`.
'bidi-import'::
This modifies the 'import' capability.
The fast-import commands 'cat-blob' and 'ls' can be used by remote-helpers
to retrieve information about blobs and trees that already exist in
fast-import's memory. This requires a channel from fast-import to the
remote-helper.
If it is advertised in addition to "import", git establishes a pipe from
fast-import to the remote-helper's stdin.
It follows that git and fast-import are both connected to the
remote-helper's stdin. Because git can send multiple commands to
the remote-helper it is required that helpers that use 'bidi-import'
buffer all 'import' commands of a batch before sending data to fast-import.
This is to prevent mixing commands and fast-import responses on the
helper's stdin.
'export-marks' <file>::
This modifies the 'export' capability, instructing git to dump the
internal marks table to <file> when complete. For details,
read up on '--export-marks=<file>' in linkgit:git-fast-export[1].
'import-marks' <file>::

HANDLING OF SVN BRANCHES
------------------------
If 'git svn' is configured to fetch branches (and --follow-branches
is in effect), it sometimes creates multiple git branches for one
SVN branch, where the addtional branches have names of the form
'branchname@nnn' (with nnn an SVN revision number). These additional
branches are created if 'git svn' cannot find a parent commit for the
first commit in an SVN branch, to connect the branch to the history of
the other branches.
Normally, the first commit in an SVN branch consists
of a copy operation. 'git svn' will read this commit to get the SVN
revision the branch was created from. It will then try to find the
git commit that corresponds to this SVN revision, and use that as the
parent of the branch. However, it is possible that there is no suitable
git commit to serve as parent. This will happen, among other reasons,
if the SVN branch is a copy of a revision that was not fetched by 'git
svn' (e.g. because it is an old revision that was skipped with
'--revision'), or if in SVN a directory was copied that is not tracked
by 'git svn' (such as a branch that is not tracked at all, or a
subdirectory of a tracked branch). In these cases, 'git svn' will still
create a git branch, but instead of using an existing git commit as the
parent of the branch, it will read the SVN history of the directory the
branch was copied from and create appropriate git commits. This is
indicated by the message "Initializing parent: <branchname>".
Additionally, it will create a special branch named
'<branchname>@<SVN-Revision>', where <SVN-Revision> is the SVN revision
number the branch was copied from. This branch will point to the newly
created parent commit of the branch. If in SVN the branch was deleted
and later recreated from a different version, there will be multiple
such branches with an '@'.
Note that this may mean that multiple git commits are created for a
single SVN revision.
An example: in an SVN repository with a standard
trunk/tags/branches layout, a directory trunk/sub is created in r.100.
In r.200, trunk/sub is branched by copying it to branches/. 'git svn
clone -s' will then create a branch 'sub'. It will also create new git
commits for r.100 through r.199 and use these as the history of branch
'sub'. Thus there will be two git commits for each revision from r.100
to r.199 (one containing trunk/, one containing trunk/sub/). Finally,
it will create a branch 'sub@200' pointing to the new parent commit of
branch 'sub' (i.e. the commit for r.200 and trunk/sub/).

you've already pushed to a remote repository for other users, and
dcommit with SVN is analogous to that.
When cloning an SVN repository, if none of the options for describing
the repository layout is used (--trunk, --tags, --branches,
--stdlayout), 'git svn clone' will create a git repository with
completely linear history, where branches and tags appear as separate
directories in the working copy. While this is the easiest way to get a
copy of a complete repository, for projects with many branches it will
lead to a working copy many times larger than just the trunk. Thus for
projects using the standard directory structure (trunk/branches/tags),
it is recommended to clone with option '--stdlayout'. If the project
uses a non-standard structure, and/or if branches and tags are not
required, it is easiest to only clone one directory (typically trunk),
without giving any repository layout options. If the full history with
branches and tags is required, the options '--trunk' / '--branches' /
'--tags' must be used.
When using multiple --branches or --tags, 'git svn' does not automatically

In SVN, it is possible (though discouraged) to commit changes to a tag
(because a tag is just a directory copy, thus technically the same as a
branch). When cloning an SVN repository, 'git svn' cannot know if such a
commit to a tag will happen in the future. Thus it acts conservatively
and imports all SVN tags as branches, prefixing the tag name with 'tags/'.

How to maintain Git
===================
Activities
----------
The maintainer's git time is spent on three activities.
- Communication (60%)
- Communication (45%)
Mailing list discussions on general design, fielding user
questions, diagnosing bug reports; reviewing, commenting on,
suggesting alternatives to, and rejecting patches.
- Integration (30%)
- Integration (50%)
Applying new patches from the contributors while spotting and
correcting minor mistakes, shuffling the integration and
testing branches, pushing the results out, cutting the
releases, and making announcements.
- Own development (10%)
- Own development (5%)
Scratching my own itch and sending proposed patch series out.
The Policy
----------
The policy on Integration is informally mentioned in "A Note
from the maintainer" message, which is periodically posted to
this mailing list after each feature release is made.
The policy.
- Feature releases are numbered as vX.Y.Z and are meant to
contain bugfixes and enhancements in any area, including
functionality, performance and usability, without regression.
- One release cycle for a feature release is expected to last for
eight to ten weeks.
- Maintenance releases are numbered as vX.Y.Z.W and are meant
to contain only bugfixes for the corresponding vX.Y.Z feature
release and earlier maintenance releases vX.Y.Z.V (V < W).

- Review the last issue of "What's cooking" again and see if topics
that are ready to be merged to 'next' are still in good shape
(e.g. has there any new issue identified on the list with the
series?)
- Prepare 'jch' branch, which is used to represent somewhere
between 'master' and 'pu' and often is slightly ahead of 'next'.
$ Meta/Reintegrate master..pu >Meta/redo-jch.sh
The result is a script that lists topics to be merged in order to
rebuild 'pu' as the input to Meta/Reintegrate script. Remove
later topics that should not be in 'jch' yet. Add a line that
consists of '### match next' before the name of the first topic
in the output that should be in 'jch' but not in 'next' yet.
- Now we are ready to start merging topics to 'next'. For each
branch whose tip is not merged to 'next', one of three things can
happen:
- The commits are all next-worthy; merge the topic to next;
- The new parts are of mixed quality, but earlier ones are
next-worthy; merge the early parts to next;
- Nothing is next-worthy; do not do anything.
This step is aided with Meta/redo-jch.sh script created earlier.
If a topic that was already in 'next' gained a patch, the script
would list it as "ai/topic~1". To include the new patch to the
updated 'next', drop the "~1" part; to keep it excluded, do not
touch the line. If a topic that was not in 'next' should be
merged to 'next', add it at the end of the list. Then:
$ git checkout -B jch master
$ Meta/redo-jch.sh -c1
to rebuild the 'jch' branch from scratch. "-c1" tells the script
to stop merging at the first line that begins with '###'
(i.e. the "### match next" line you added earlier).
At this point, build-test the result. It may reveal semantic
conflicts (e.g. a topic renamed a variable, another added a new
reference to the variable under its old name), in which case
prepare an appropriate merge-fix first (see appendix), and
rebuild the 'jch' branch from scratch, starting at the tip of
'master'.
Then do the same to 'next'
$ git checkout next
$ sh Meta/redo-jch.sh -c1 -e
The "-e" option allows the merge message that comes from the
history of the topic and the comments in the "What's cooking" to
be edited. The resulting tree should match 'jch' as the same set
of topics are merged on 'master'; otherwise there is a mismerge.
Investigate why and do not proceed until the mismerge is found
and rectified.
$ git diff jch next
When all is well, clean up the redo-jch.sh script with
$ sh Meta/redo-jch.sh -u
This removes topics listed in the script that have already been
merged to 'master'. This may lose '### match next' marker;
add it again to the appropriate place when it happens.
- Rebuild 'pu'.
$ Meta/Reintegrate master..pu >Meta/redo-pu.sh
Edit the result by adding new topics that are not still in 'pu'
in the script. Then
$ git checkout -B pu jch
$ sh Meta/redo-pu.sh
When all is well, clean up the redo-pu.sh script with
$ sh Meta/redo-pu.sh -u
Double check by running
$ git branch --no-merged pu
to see there is no unexpected leftover topics.
At this point, build-test the result for semantic conflicts, and
if there are, prepare an appropriate merge-fix first (see
appendix), and rebuild the 'pu' branch from scratch, starting at
the tip of 'jch'.
- Update "What's cooking" message to review the updates to
existing topics, newly added topics and graduated topics.

This step is helped with Meta/cook script.
- Merge topics to 'next'. For each branch whose tip is not
merged to 'next', one of three things can happen:
$ Meta/cook
- The commits are all next-worthy; merge the topic to next:
This script inspects the history between master..pu, finds tips
of topic branches, compares what it found with the current
contents in Meta/whats-cooking.txt, and updates that file.
Topics not listed in the file but are found in master..pu are
added to the "New topics" section, topics listed in the file that
are no longer found in master..pu are moved to the "Graduated to
master" section, and topics whose commits changed their states
(e.g. used to be only in 'pu', now merged to 'next') are updated
with change markers "<<" and ">>".
$ git checkout next
$ git merge ai/topic ;# or "git merge ai/maint-topic"
$ make test
Look for lines enclosed in "<<" and ">>"; they hold contents from
old file that are replaced by this integration round. After
verifying them, remove the old part. Review the description for
each topic and update its doneness and plan as needed. To review
the updated plan, run
- The new parts are of mixed quality, but earlier ones are
next-worthy; merge the early parts to next:
$ Meta/cook -w
$ git checkout next
$ git merge ai/topic~2 ;# the tip two are dubious
$ make test
which will pick up comments given to the topics, such as "Will
merge to 'next'", etc. (see Meta/cook script to learn what kind
of phrases are supported).
- Nothing is next-worthy; do not do anything.
- Compile, test and install all four (five) integration branches;
Meta/Dothem script may aid this step.
- [** OBSOLETE **] Optionally rebase topics that do not have any commit
in next yet, when they can take advantage of low-level framework
change that is merged to 'master' already.
- Format documentation if the 'master' branch was updated;
Meta/dodoc.sh script may aid this step.
$ git rebase master ai/topic
This step is helped with Meta/git-topic.perl script to
identify which topic is rebaseable. There also is a
pre-rebase hook to make sure that topics that are already in
'next' are not rebased beyond the merged commit.
- [** OBSOLETE **] Rebuild "pu" to merge the tips of topics not in 'next'.
$ git checkout pu
$ git reset --hard next
$ git merge ai/topic ;# repeat for all remaining topics
$ make test
This step is helped with Meta/PU script
- Push four integration branches to a private repository at
k.org and run "make test" on all of them.
- Push four integration branches to /pub/scm/git/git.git at
k.org. This triggers its post-update hook which:
(1) runs "git pull" in $HOME/git-doc/ repository to pull
'master' just pushed out;
(2) runs "make doc" in $HOME/git-doc/, install the generated
documentation in staging areas, which are separate
repositories that have html and man branches checked
out.
(3) runs "git commit" in the staging areas, and run "git
push" back to /pub/scm/git/git.git/ to update the html
and man branches.
(4) installs generated documentation to /pub/software/scm/git/docs/
to be viewed from http://www.kernel.org/
- Fetch html and man branches back from k.org, and push four
integration branches and the two documentation branches to
repo.or.cz and other mirrors.
- Push the integration branches out to public places; Meta/pushall
script may aid this step.

Appendix
--------
Preparing a "merge-fix"
~~~~~~~~~~~~~~~~~~~~~~~
A merge of two topics may not textually conflict but still have
conflict at the semantic level. A classic example is for one topic
to rename an variable and all its uses, while another topic adds a
new use of the variable under its old name. When these two topics
are merged together, the reference to the variable newly added by
the latter topic will still use the old name in the result.
The Meta/Reintegrate script that is used by redo-jch and redo-pu
scripts implements a crude but usable way to work this issue around.
When the script merges branch $X, it checks if "refs/merge-fix/$X"
exists, and if so, the effect of it is squashed into the result of
the mechanical merge. In other words,
$ echo $X | Meta/Reintegrate
is roughly equivalent to this sequence:
$ git merge --rerere-autoupdate $X
$ git commit
$ git cherry-pick -n refs/merge-fix/$X
$ git commit --amend
The goal of this "prepare a merge-fix" step is to come up with a
commit that can be squashed into a result of mechanical merge to
correct semantic conflicts.
After finding that the result of merging branch "ai/topic" to an
integration branch had such a semantic conflict, say pu~4, check the
problematic merge out on a detached HEAD, edit the working tree to
fix the semantic conflict, and make a separate commit to record the
fix-up:
$ git checkout pu~4
$ git show -s --pretty=%s ;# double check
Merge branch 'ai/topic' to pu
$ edit
$ git commit -m 'merge-fix/ai/topic' -a
Then make a reference "refs/merge-fix/ai/topic" to point at this
result:
$ git update-ref refs/merge-fix/ai/topic HEAD
Then double check the result by asking Meta/Reintegrate to redo the
merge:
$ git checkout pu~5 ;# the parent of the problem merge
$ echo ai/topic | Meta/Reintegrate
$ git diff pu~4
This time, because you prepared refs/merge-fix/ai/topic, the
resulting merge should have been tweaked to include the fix for the
semantic conflict.
Note that this assumes that the order in which conflicting branches
are merged does not change. If the reason why merging ai/topic
branch needs this merge-fix is because another branch merged earlier
to the integration branch changed the underlying assumption ai/topic
branch made (e.g. ai/topic branch added a site to refer to a
variable, while the other branch renamed that variable and adjusted
existing use sites), and if you changed redo-jch (or redo-pu) script
to merge ai/topic branch before the other branch, then the above
merge-fix should not be applied while merging ai/topic, but should
instead be applied while merging the other branch. You would need
to move the fix to apply to the other branch, perhaps like this:
$ mf=refs/merge-fix
$ git update-ref $mf/$the_other_branch $mf/ai/topic
$ git update-ref -d $mf/ai/topic

Abstract: This is how-to documentation for people who want to add extension
commands to git. It should be read alongside api-builtin.txt.
Content-type: text/asciidoc
How to integrate new subcommands
================================
This is how-to documentation for people who want to add extension
commands to git. It should be read alongside api-builtin.txt.
Runtime environment
-------------------
git subcommands are standalone executables that live in the git exec
path, normally /usr/lib/git-core. The git executable itself is a
thin wrapper that knows where the subcommands live, and runs them by
passing command-line arguments to them.
(If "git foo" is not found in the git exec path, the wrapper
will look in the rest of your $PATH for it. Thus, it's possible
to write local git extensions that don't live in system space.)
Implementation languages
------------------------
Most subcommands are written in C or shell. A few are written in
Perl.
While we strongly encourage coding in portable C for portability,
these specific scripting languages are also acceptable. We won't
accept more without a very strong technical case, as we don't want
to broaden the git suite's required dependencies. Import utilities,
surgical tools, remote helpers and other code at the edges of the
git suite are more lenient and we allow Python (and even Tcl/tk),
but they should not be used for core functions.
This may change in the future. Especially Python is not allowed in
core because we need better Python integration in the git Windows
installer before we can be confident people in that environment
won't experience an unacceptably large loss of capability.
C commands are normally written as single modules, named after the
command, that link a collection of functions called libgit. Thus,
your command 'git-foo' would normally be implemented as a single
"git-foo.c" (or "builtin/foo.c" if it is to be linked to the main
binary); this organization makes it easy for people reading the code
to find things.
See the CodingGuidelines document for other guidance on what we consider
good practice in C and shell, and api-builtin.txt for the support
functions available to built-in commands written in C.
What every extension command needs
----------------------------------
You must have a man page, written in asciidoc (this is what git help
followed by your subcommand name will display). Be aware that there is
a local asciidoc configuration and macros which you should use. It's
often helpful to start by cloning an existing page and replacing the
text content.
You must have a test, written to report in TAP (Test Anything Protocol).
Tests are executables (usually shell scripts) that live in the 't'
subdirectory of the tree. Each test name begins with 't' and a sequence
number that controls where in the test sequence it will be executed;
conventionally the rest of the name stem is that of the command
being tested.
Read the file t/README to learn more about the conventions to be used
in writing tests, and the test support library.
Integrating a command
---------------------
Here are the things you need to do when you want to merge a new
subcommand into the git tree.
1. Don't forget to sign off your patch!
2. Append your command name to one of the variables BUILTIN_OBJS,
EXTRA_PROGRAMS, SCRIPT_SH, SCRIPT_PERL or SCRIPT_PYTHON.
3. Drop its test in the t directory.
4. If your command is implemented in an interpreted language with a
p-code intermediate form, make sure .gitignore in the main directory
includes a pattern entry that ignores such files. Python .pyc and
.pyo files will already be covered.
5. If your command has any dependency on a particular version of
your language, document it in the INSTALL file.
6. There is a file command-list.txt in the distribution main directory
that categorizes commands by type, so they can be listed in appropriate
subsections in the documentation's summary command list. Add an entry
for yours. To understand the categories, look at git-cmmands.txt
in the main directory.
7. Give the maintainer one paragraph to include in the RelNotes file
to describe the new feature; a good place to do so is in the cover
letter [PATCH 0/n].
That's all there is to it.

NOME
----
gittutorial - Um tutorial de introdução ao git (para versão 1.5.1 ou mais nova)
SINOPSE
--------
git *
DESCRIÇÃO
-----------
Este tutorial explica como importar um novo projeto para o git,
adicionar mudanças a ele, e compartilhar mudanças com outros
desenvolvedores.
Se, ao invés disso, você está interessado primariamente em usar git para
obter um projeto, por exemplo, para testar a última versão, você pode
preferir começar com os primeiros dois capítulos de
link:user-manual.html[O Manual do Usuário Git].
Primeiro, note que você pode obter documentação para um comando como
`git log --graph` com:
------------------------------------------------
$ man git-log
------------------------------------------------
ou:
------------------------------------------------
$ git help log
------------------------------------------------
Com a última forma, você pode usar o visualizador de manual de sua
escolha; veja linkgit:git-help[1] para maior informação.
É uma boa idéia informar ao git seu nome e endereço público de email
antes de fazer qualquer operação. A maneira mais fácil de fazê-lo é:
------------------------------------------------
$ git config --global user.name "Seu Nome Vem Aqui"
$ git config --global user.email voce@seudominio.exemplo.com
------------------------------------------------
Importando um novo projeto
-----------------------
Assuma que você tem um tarball project.tar.gz com seu trabalho inicial.
Você pode colocá-lo sob controle de revisão git da seguinte forma:
------------------------------------------------
$ tar xzf project.tar.gz
$ cd project
$ git init
------------------------------------------------
Git irá responder
------------------------------------------------
Initialized empty Git repository in .git/
------------------------------------------------
Agora que você iniciou seu diretório de trabalho, você deve ter notado que um
novo diretório foi criado com o nome de ".git".
A seguir, diga ao git para gravar um instantâneo do conteúdo de todos os
arquivos sob o diretório atual (note o '.'), com 'git-add':
------------------------------------------------
$ git add .
------------------------------------------------
Este instantâneo está agora armazenado em uma área temporária que o git
chama de "index" ou índice. Você pode armazenar permanentemente o
conteúdo do índice no repositório com 'git-commit':
------------------------------------------------
$ git commit
------------------------------------------------
Isto vai te pedir por uma mensagem de commit. Você agora gravou sua
primeira versão de seu projeto no git.
Fazendo mudanças
--------------
Modifique alguns arquivos, e, então, adicione seu conteúdo atualizado ao
índice:
------------------------------------------------
$ git add file1 file2 file3
------------------------------------------------
Você está agora pronto para fazer o commit. Você pode ver o que está
para ser gravado usando 'git-diff' com a opção --cached:
------------------------------------------------
$ git diff --cached
------------------------------------------------
(Sem --cached, o comando 'git-diff' irá te mostrar quaisquer mudanças
que você tenha feito mas ainda não adicionou ao índice.) Você também
pode obter um breve sumário da situação com 'git-status':
------------------------------------------------
$ git status
# On branch master
# Changes to be committed:
# (use "git reset HEAD <file>..." to unstage)
#
# modified: file1
# modified: file2
# modified: file3
#
------------------------------------------------
Se você precisar fazer qualquer outro ajuste, faça-o agora, e, então,
adicione qualquer conteúdo modificado ao índice. Finalmente, grave suas
mudanças com:
------------------------------------------------
$ git commit
------------------------------------------------
Ao executar esse comando, ele irá te pedir uma mensagem descrevendo a mudança,
e, então, irá gravar a nova versão do projeto.
Alternativamente, ao invés de executar 'git-add' antes, você pode usar
------------------------------------------------
$ git commit -a
------------------------------------------------
o que irá automaticamente notar quaisquer arquivos modificados (mas não
novos), adicioná-los ao índices, e gravar, tudo em um único passo.
Uma nota em mensagens de commit: Apesar de não ser exigido, é uma boa
idéia começar a mensagem com uma simples e curta (menos de 50
caracteres) linha sumarizando a mudança, seguida de uma linha em branco
e, então, uma descrição mais detalhada. Ferramentas que transformam
commits em email, por exemplo, usam a primeira linha no campo de
cabeçalho "Subject:" e o resto no corpo.
Git rastreia conteúdo, não arquivos
----------------------------
Muitos sistemas de controle de revisão provêem um comando `add` que diz
ao sistema para começar a rastrear mudanças em um novo arquivo. O
comando `add` do git faz algo mais simples e mais poderoso: 'git-add' é
usado tanto para arquivos novos e arquivos recentemente modificados, e
em ambos os casos, ele tira o instantâneo dos arquivos dados e armazena
o conteúdo no índice, pronto para inclusão do próximo commit.
Visualizando a história do projeto
-----------------------
Em qualquer ponto você pode visualizar a história das suas mudanças
usando
------------------------------------------------
$ git log
------------------------------------------------
Se você também quiser ver a diferença completa a cada passo, use
------------------------------------------------
$ git log -p
------------------------------------------------
Geralmente, uma visão geral da mudança é útil para ter a sensação de
cada passo
------------------------------------------------
$ git log --stat --summary
------------------------------------------------
Gerenciando "branches"/ramos
-----------------
Um simples repositório git pode manter múltiplos ramos de
desenvolvimento. Para criar um novo ramo chamado "experimental", use
------------------------------------------------
$ git branch experimental
------------------------------------------------
Se você executar agora
------------------------------------------------
$ git branch
------------------------------------------------
você vai obter uma lista de todos os ramos existentes:
------------------------------------------------
experimental
* master
------------------------------------------------
O ramo "experimental" é o que você acaba de criar, e o ramo "master" é o
ramo padrão que foi criado pra você automaticamente. O asterisco marca
o ramo em que você está atualmente; digite
------------------------------------------------
$ git checkout experimental
------------------------------------------------
para mudar para o ramo experimental. Agora edite um arquivo, grave a
mudança, e mude de volta para o ramo master:
------------------------------------------------
(edita arquivo)
$ git commit -a
$ git checkout master
------------------------------------------------
Verifique que a mudança que você fez não está mais visível, já que ela
foi feita no ramo experimental e você está de volta ao ramo master.
Você pode fazer uma mudança diferente no ramo master:
------------------------------------------------
(edit file)
$ git commit -a
------------------------------------------------
neste ponto, os dois ramos divergiram, com diferentes mudanças feitas em
cada um. Para unificar as mudanças feitas no experimental para o
master, execute
------------------------------------------------
$ git merge experimental
------------------------------------------------
Se as mudanças não conflitarem, estará pronto. Se existirem conflitos,
marcadores serão deixados nos arquivos problemáticos exibindo o
conflito;
------------------------------------------------
$ git diff
------------------------------------------------
vai exibir isto. Após você editar os arquivos para resolver os
conflitos,
------------------------------------------------
$ git commit -a
------------------------------------------------
irá gravar o resultado da unificação. Finalmente,
------------------------------------------------
$ gitk
------------------------------------------------
vai mostrar uma bela representação gráfica da história resultante.
Neste ponto você pode remover seu ramo experimental com
------------------------------------------------
$ git branch -d experimental
------------------------------------------------
Este comando garante que as mudanças no ramo experimental já estão no
ramo atual.
Se você desenvolve em um ramo ideia-louca, e se arrepende, você pode
sempre remover o ramo com
-------------------------------------
$ git branch -D ideia-louca
-------------------------------------
Ramos são baratos e fáceis, então isto é uma boa maneira de experimentar
alguma coisa.
Usando git para colaboração
---------------------------
Suponha que Alice começou um novo projeto com um repositório git em
/home/alice/project, e que Bob, que tem um diretório home na mesma
máquina, quer contribuir.
Bob começa com:
------------------------------------------------
bob$ git clone /home/alice/project myrepo
------------------------------------------------
Isso cria um novo diretório "myrepo" contendo um clone do repositório de
Alice. O clone está no mesmo pé que o projeto original, possuindo sua
própria cópia da história do projeto original.
Bob então faz algumas mudanças e as grava:
------------------------------------------------
(editar arquivos)
bob$ git commit -a
(repetir conforme necessário)
------------------------------------------------
Quanto está pronto, ele diz a Alice para puxar as mudanças do
repositório em /home/bob/myrepo. Ela o faz com:
------------------------------------------------
alice$ cd /home/alice/project
alice$ git pull /home/bob/myrepo master
------------------------------------------------
Isto unifica as mudanças do ramo "master" do Bob ao ramo atual de Alice.
Se Alice fez suas próprias mudanças no intervalo, ela, então, pode
precisar corrigir manualmente quaisquer conflitos. (Note que o argumento
"master" no comando acima é, de fato, desnecessário, já que é o padrão.)
O comando "pull" executa, então, duas operações: ele obtém mudanças de
um ramo remoto, e, então, as unifica no ramo atual.
Note que, em geral, Alice gostaria que suas mudanças locais fossem
gravadas antes de iniciar este "pull". Se o trabalho de Bob conflita
com o que Alice fez desde que suas histórias se ramificaram, Alice irá
usar seu diretório de trabalho e o índice para resolver conflitos, e
mudanças locais existentes irão interferir com o processo de resolução
de conflitos (git ainda irá realizar a obtenção mas irá se recusar a
unificar --- Alice terá que se livrar de suas mudanças locais de alguma
forma e puxar de novo quando isso acontecer).
Alice pode espiar o que Bob fez sem unificar primeiro, usando o comando
"fetch"; isto permite Alice inspecionar o que Bob fez, usando um símbolo
especial "FETCH_HEAD", com o fim de determinar se ele tem alguma coisa
que vale puxar, assim:
------------------------------------------------
alice$ git fetch /home/bob/myrepo master
alice$ git log -p HEAD..FETCH_HEAD
------------------------------------------------
Esta operação é segura mesmo se Alice tem mudanças locais não gravadas.
A notação de intervalo "HEAD..FETCH_HEAD" significa mostrar tudo que é
alcançável de FETCH_HEAD mas exclua tudo o que é alcançável de HEAD.
Alice já sabe tudo que leva a seu estado atual (HEAD), e revisa o que Bob
tem em seu estado (FETCH_HEAD) que ela ainda não viu com esse comando.
Se Alice quer visualizar o que Bob fez desde que suas histórias se
ramificaram, ela pode disparar o seguinte comando:
------------------------------------------------
$ gitk HEAD..FETCH_HEAD
------------------------------------------------
Isto usa a mesma notação de intervalo que vimos antes com 'git log'.
Alice pode querer ver o que ambos fizeram desde que ramificaram. Ela
pode usar a forma com três pontos ao invés da forma com dois pontos:
------------------------------------------------
$ gitk HEAD...FETCH_HEAD
------------------------------------------------
Isto significa "mostre tudo que é alcançável de qualquer um deles, mas
exclua tudo que é alcançável a partir de ambos".
Por favor, note que essas notações de intervalo podem ser usadas tanto
com gitk quanto com "git log".
Após inspecionar o que Bob fez, se não há nada urgente, Alice pode
decidir continuar trabalhando sem puxar de Bob. Se a história de Bob
tem alguma coisa que Alice precisa imediatamente, Alice pode optar por
separar seu trabalho em progresso primeiro, fazer um "pull", e, então,
finalmente, retomar seu trabalho em progresso em cima da história
resultante.
Quando você está trabalhando em um pequeno grupo unido, não é incomum
interagir com o mesmo repositório várias e várias vezes. Definindo um
repositório remoto antes de tudo, você pode fazê-lo mais facilmente:
------------------------------------------------
alice$ git remote add bob /home/bob/myrepo
------------------------------------------------
Com isso, Alice pode executar a primeira parte da operação "pull" usando
o comando 'git-fetch' sem unificar suas mudanças com seu próprio ramo,
usando:
-------------------------------------
alice$ git fetch bob
-------------------------------------
Diferente da forma longa, quando Alice obteve de Bob usando um
repositório remoto antes definido com 'git-remote', o que foi obtido é
armazenado em um ramo remoto, neste caso `bob/master`. Então, após isso:
-------------------------------------
alice$ git log -p master..bob/master
-------------------------------------
mostra uma lista de todas as mudanças que Bob fez desde que ramificou do
ramo master de Alice.
Após examinar essas mudanças, Alice pode unificá-las em seu ramo master:
-------------------------------------
alice$ git merge bob/master
-------------------------------------
Esse `merge` pode também ser feito puxando de seu próprio ramo remoto,
assim:
-------------------------------------
alice$ git pull . remotes/bob/master
-------------------------------------
Note que 'git pull' sempre unifica ao ramo atual, independente do que
mais foi passado na linha de comando.
Depois, Bob pode atualizar seu repositório com as últimas mudanças de
Alice, usando
-------------------------------------
bob$ git pull
-------------------------------------
Note que ele não precisa dar o caminho do repositório de Alice; quando
Bob clonou seu repositório, o git armazenou a localização de seu
repositório na configuração do mesmo, e essa localização é usada
para puxar:
-------------------------------------
bob$ git config --get remote.origin.url
/home/alice/project
-------------------------------------
(A configuração completa criada por 'git-clone' é visível usando `git
config -l`, e a página de manual linkgit:git-config[1] explica o
significado de cada opção.)
Git também mantém uma cópia limpa do ramo master de Alice sob o nome
"origin/master":
-------------------------------------
bob$ git branch -r
origin/master
-------------------------------------
Se Bob decidir depois em trabalhar em um host diferente, ele ainda pode
executar clones e puxar usando o protocolo ssh:
-------------------------------------
bob$ git clone alice.org:/home/alice/project myrepo
-------------------------------------
Alternativamente, o git tem um protocolo nativo, ou pode usar rsync ou
http; veja linkgit:git-pull[1] para detalhes.
Git pode também ser usado em um modo parecido com CVS, com um
repositório central para o qual vários usuários empurram modificações;
veja linkgit:git-push[1] e linkgit:gitcvs-migration[7].
Explorando história
-----------------
A história no git é representada como uma série de commits
interrelacionados. Nós já vimos que o comando 'git-log' pode listar
esses commits. Note que a primeira linha de cada entrada no log também
dá o nome para o commit:
-------------------------------------
$ git log
commit c82a22c39cbc32576f64f5c6b3f24b99ea8149c7
Author: Junio C Hamano <junkio@cox.net>
Date: Tue May 16 17:18:22 2006 -0700
merge-base: Clarify the comments on post processing.
-------------------------------------
Nós podemos dar este nome ao 'git-show' para ver os detalhes sobre este
commit.
-------------------------------------
$ git show c82a22c39cbc32576f64f5c6b3f24b99ea8149c7
-------------------------------------
Mas há outras formas de se referir aos commits. Você pode usar qualquer
parte inicial do nome que seja longo o bastante para identificar
unicamente o commit:
-------------------------------------
$ git show c82a22c39c # os primeiros caracteres do nome são o bastante
# usualmente
$ git show HEAD # a ponta do ramo atual
$ git show experimental # a ponta do ramo "experimental"
-------------------------------------
Todo commit normalmente tem um commit "pai" que aponta para o estado
anterior do projeto:
-------------------------------------
$ git show HEAD^ # para ver o pai de HEAD
$ git show HEAD^^ # para ver o avô de HEAD
$ git show HEAD~4 # para ver o trisavô de HEAD
-------------------------------------
Note que commits de unificação podem ter mais de um pai:
-------------------------------------
$ git show HEAD^1 # mostra o primeiro pai de HEAD (o mesmo que HEAD^)
$ git show HEAD^2 # mostra o segundo pai de HEAD
-------------------------------------
Você também pode dar aos commits nomes à sua escolha; após executar
-------------------------------------
$ git tag v2.5 1b2e1d63ff
-------------------------------------
você pode se referir a 1b2e1d63ff pelo nome "v2.5". Se você pretende
compartilhar esse nome com outras pessoas (por exemplo, para identificar
uma versão de lançamento), você deveria criar um objeto "tag", e talvez
assiná-lo; veja linkgit:git-tag[1] para detalhes.
Qualquer comando git que precise conhecer um commit pode receber
quaisquer desses nomes. Por exemplo:
-------------------------------------
$ git diff v2.5 HEAD # compara o HEAD atual com v2.5
$ git branch stable v2.5 # inicia um novo ramo chamado "stable" baseado
# em v2.5
$ git reset --hard HEAD^ # reseta seu ramo atual e seu diretório de
# trabalho a seu estado em HEAD^
-------------------------------------
Seja cuidadoso com o último comando: além de perder quaisquer mudanças
em seu diretório de trabalho, ele também remove todos os commits
posteriores desse ramo. Se esse ramo é o único ramo contendo esses
commits, eles serão perdidos. Também, não use 'git-reset' num ramo
publicamente visível de onde outros desenvolvedores puxam, já que vai
forçar unificações desnecessárias para que outros desenvolvedores limpem
a história. Se você precisa desfazer mudanças que você empurrou, use
'git-revert' no lugar.
O comando 'git-grep' pode buscar strings em qualquer versão de seu
projeto, então
-------------------------------------
$ git grep "hello" v2.5
-------------------------------------
procura por todas as ocorrências de "hello" em v2.5.
Se você deixar de fora o nome do commit, 'git-grep' irá procurar
quaisquer dos arquivos que ele gerencia no diretório corrente. Então
-------------------------------------
$ git grep "hello"
-------------------------------------
é uma forma rápida de buscar somente os arquivos que são rastreados pelo
git.
Muitos comandos git também recebem um conjunto de commits, o que pode
ser especificado de várias formas. Aqui estão alguns exemplos com 'git-log':
-------------------------------------
$ git log v2.5..v2.6 # commits entre v2.5 e v2.6
$ git log v2.5.. # commits desde v2.5
$ git log --since="2 weeks ago" # commits das últimas 2 semanas
$ git log v2.5.. Makefile # commits desde v2.5 que modificam
# Makefile
-------------------------------------
Você também pode dar ao 'git-log' um "intervalo" de commits onde o
primeiro não é necessariamente um ancestral do segundo; por exemplo, se
as pontas dos ramos "stable" e "master" divergiram de um commit
comum algum tempo atrás, então
-------------------------------------
$ git log stable..master
-------------------------------------
irá listar os commits feitos no ramo "master" mas não no ramo
"stable", enquanto
-------------------------------------
$ git log master..stable
-------------------------------------
irá listar a lista de commits feitos no ramo "stable" mas não no ramo
"master".
O comando 'git-log' tem uma fraqueza: ele precisa mostrar os commits em
uma lista. Quando a história tem linhas de desenvolvimento que
divergiram e então foram unificadas novamente, a ordem em que 'git-log'
apresenta essas mudanças é irrelevante.
A maioria dos projetos com múltiplos contribuidores (como o kernel
Linux, ou o próprio git) tem unificações frequentes, e 'gitk' faz um
trabalho melhor de visualizar sua história. Por exemplo,
-------------------------------------
$ gitk --since="2 weeks ago" drivers/
-------------------------------------
permite a você navegar em quaisquer commits desde as últimas duas semanas
de commits que modificaram arquivos sob o diretório "drivers". (Nota:
você pode ajustar as fontes do gitk segurando a tecla control enquanto
pressiona "-" ou "+".)
Finalmente, a maioria dos comandos que recebem nomes de arquivo permitirão
também, opcionalmente, preceder qualquer nome de arquivo por um
commit, para especificar uma versão particular do arquivo:
-------------------------------------
$ git diff v2.5:Makefile HEAD:Makefile.in
-------------------------------------
Você pode usar 'git-show' para ver tal arquivo:
-------------------------------------
$ git show v2.5:Makefile
-------------------------------------
Próximos passos
----------
Este tutorial deve ser o bastante para operar controle de revisão
distribuído básico para seus projetos. No entanto, para entender
plenamente a profundidade e o poder do git você precisa entender duas
idéias simples nas quais ele se baseia:
* A base de objetos é um sistema bem elegante usado para armazenar a
história de seu projeto--arquivos, diretórios, e commits.
* O arquivo de índice é um cache do estado de uma árvore de diretório,
usado para criar commits, restaurar diretórios de trabalho, e
armazenar as várias árvores envolvidas em uma unificação.
A parte dois deste tutorial explica a base de objetos, o arquivo de
índice, e algumas outras coisinhas que você vai precisar pra usar o
máximo do git. Você pode encontrá-la em linkgit:gittutorial-2[7].
Se você não quiser continuar com o tutorial agora nesse momento, algumas
outras digressões que podem ser interessantes neste ponto são:
* linkgit:git-format-patch[1], linkgit:git-am[1]: Estes convertem
séries de commits em patches para email, e vice-versa, úteis para
projetos como o kernel Linux que dependem fortemente de patches
enviados por email.
* linkgit:git-bisect[1]: Quando há uma regressão em seu projeto, uma
forma de rastrear um bug é procurando pela história para encontrar o
commit culpado. Git bisect pode ajudar a executar uma busca binária
por esse commit. Ele é inteligente o bastante para executar uma
busca próxima da ótima mesmo no caso de uma história complexa
não-linear com muitos ramos unificados.
* link:everyday.html[GIT diariamente com 20 e tantos comandos]
* linkgit:gitcvs-migration[7]: Git para usuários de CVS.

`format-patch` places after the commit message but before the patch
