The current code wants to record an error condition from
either ferror() or fclose(), but makes sure that we always
call both functions. So it can't use logical-OR "||", which
would short-circuit when ferror() is true. Instead, it uses
bitwise-OR "|" to evaluate both functions and set one or
more bits in the "err" flag if they reported a failure.
Unlike logical-OR, though, bitwise-OR does not introduce a
sequence point, and the order of evaluation for its operands
is unspecified. So a compiler would be free to generate code
which calls fclose() first, and then ferror() on the
now-freed filehandle.
There's no indication that this has happened in practice,
but let's write it out in a way that follows the standard.

When removing the hack for isatty(), we actually removed more than just
an isatty() hack: we removed the hack where internal data structures of
the MSVC runtime are modified in order to redirect stdout/stderr.
Instead of using that hack (that does not work with newer versions of
the runtime, anyway), we replaced it by reopening the respective file
descriptors.
What we forgot was to mark stderr as unbuffered again.

The documentation gives an example of the submodule foreach
command that uses both backticks and single-quotes. We stick
the whole thing inside "+" markers to make it monospace, but
the inside punctuation still needs escaping. We handle the
backticks with "{backtick}", and use backslash-escaping for
the single-quotes.
But we missed the escaping on the second quote. Fortunately,
asciidoc renders this unbalanced quote as we want (showing
the quote), but asciidoctor does not. We could fix it by
adding the missing backslash.
However, let's take a step back. Even when rendered
correctly, it's hard to read a long command stuck into the
middle of a paragraph, and the important punctuation is hard
to notice. Let's instead bump it into its own single-line
code block. That makes both the source and the rendered
result more readable, and as a bonus we don't have to worry
about quoting at all.

prune_cache() first identifies those entries at the start of the sorted

Last it identifies the unwanted trailing entries among the moved ones

different from the "added" paths. Consequently, these files were not

When using non-builtin protocols relying on a transport helper
(such as http), push options are not propagated to the helper.
The user could ask for push options and a push would seemingly succeed,
but the push options would never be transported to the server,
misleading the users expectation.
Fix this by propagating the push options to the transport helper.
This is only addressing the first issue of
(1) the helper protocol does not propagate push-option
(2) the http helper is not prepared to handle push-option
Once we fix (2), the http transport helper can make use of push options
as well, but that happens as a follow up. (1) is a bug fix, whereas (2)
is a feature, which is why we only do (1) here.

If you run "git log --graph --name-only", the pathnames are

on the --raw format functions. It's only --name-only which
uses its own code (and this fix mirrors the code in

Note that the tests don't follow our usual style of setting

Prior to c2f41bf52 (color.c: fix color_parse_mem() with
value_len == 0, 2017-01-19), the empty string was
interpreted as a color "reset". This was an accidental
outcome, and that commit turned it into an error.
However, scripts may pass the empty string as a default
value to "git config --get-color" to disable color when the
value is not defined. The git-add--interactive script does
this. As a result, the script is unusable since c2f41bf52
unless you have color.diff.plain defined (if it is defined,
then we don't parse the empty default at all).
Our test scripts didn't notice the recent breakage because
they run without a terminal, and thus without color. They
never hit this code path at all. And nobody noticed the
original buggy "reset" behavior, because it was effectively
a noop.
Let's fix the code to have an empty color name produce an
empty sequence of color codes. The tests need a few fixups:
- we'll add a new test in t4026 to cover this case. But
note that we need to tweak the color() helper. While
we're there, let's factor out the literal ANSI ESC
character. Otherwise it makes the diff quite hard to
read.
- we'll add a basic sanity-check in t4026 that "git add
-p" works at all when color is enabled. That would have
caught this bug, as well as any others that are specific
to the color code paths.
- 73c727d69 (log --graph: customize the graph lines with
config log.graphColors, 2017-01-19) added a test to
t4202 that checks some "invalid" graph color config.
Since ",, blue" before yielded only "blue" as valid, and
now yields "empty, empty, blue", we don't match the
expected output.
One way to fix this would be to change the expectation
to the empty color strings. But that makes the test much
less interesting, since we show only two graph lines,
both of which would be colorless.
Since the empty-string case is now covered by t4026,
let's remove them entirely here. They're just in the way
of the primary thing the test is supposed to be
checking.

The default behavior of update-ref to create reflogs differs in
repositories with worktree and bare ones. The existing tests cover only
the behavior of repositories with worktree.
This commit adds tests that assert the correct behavior in bare
repositories for update-ref. Two cases are covered:
- If core.logAllRefUpdates is not set, no reflogs should be created
- If core.logAllRefUpdates is true, reflogs should be created
Signed-off-by: Cornelius Weig <cornelius.weig@tngtech.com>
Signed-off-by: Junio C Hamano <gitster@pobox.com>
When core.logallrefupdates is true, we only create a new reflog for refs
that are under certain well-known hierarchies. The reason is that we
know that some hierarchies (like refs/tags) are not meant to change, and
that unknown hierarchies might not want reflogs at all (e.g., a
hypothetical refs/foo might be meant to change often and drop old
history immediately).
However, sometimes it is useful to override this decision and simply log
for all refs, because the safety and audit trail is more important than
the performance implications of keeping the log around.
This patch introduces a new "always" mode for the core.logallrefupdates
option which will log updates to everything under refs/, regardless
where in the hierarchy it is (we still will not log things like
ORIG_HEAD and FETCH_HEAD, which are known to be transient).

When running git-p4 on Windows, with multiple git-p4.mapUser entries in
git config - no user mappings are applied to the generated repository.
Reproduction Steps:
1. Add multiple git-p4.mapUser entries to git config on a Windows
machine
2. Attempt to clone a p4 repository
None of the user mappings will be applied.
This issue is actually caused by gitConfigList, using split(os.linesep)
to convert the output of git config --get-all into a list. On Windows,
os.linesep is equal to '\r\n' - however git.exe returns configuration
with a line seperator of '\n'.
This leads to the list returned by gitConfigList containing only one
element - which contains the full output of git config --get-all in
string form, which causes problems for the code introduced to
getUserMapFromPerforceServer in 10d08a149d ("git-p4: map a P4 user to
Git author name and email address", 2016-03-01)
This issue should be caught by the test introduced in 10d08a1, however
would require running on Windows to reproduce.
Using splitlines solves this issue, by splitting config on all
typical delimiters ('\n', '\r\n' etc.)

On Windows, executables need to have the file extension `.exe`, or they
are not executables. Hence, to support scripts, Git for Windows also
looks for a she-bang line by opening the file in question, and executing
it via the specified script interpreter.
To figure out whether files in the `PATH` are executable, `git help` has
code that imitates this behavior. With one exception: it *always* opens
the files and looks for a she-bang line *or* an `MZ` tell-tale
(nevermind that files with the magic `MZ` but without file extension
`.exe` would still not be executable).
Opening this many files leads to performance problems that are even more
serious when a virus scanner is running. Therefore, let's change the
code to look for the file extension `.exe` early, and avoid opening the
file altogether if we already know that it is executable.
See the following measurements (in seconds) as an example, where we
execute a simple program that simply lists the directory contents and
calls open() on every listed file:

This patch automates the process of determining which tests failed
previously and re-running them.
While developing patch series, it is a good practice to run the test
suite from time to time, just to make sure that obvious bugs are caught
early. With complex patch series, it is common to run `make -j15 -k
test`, i.e. run the tests in parallel and *not* stop at the first
failing test but continue. This has the advantage of identifying
possibly multiple problems in one big test run.
It is particularly important to reduce the turn-around time thusly on
Windows, where the test suite spends 45 minutes on the computer on which
this patch was developed.
It is the most convenient way to determine which tests failed after
running the entire test suite, in parallel, to look for left-over "trash
directory.t*" subdirectories in the t/ subdirectory. However, those
directories might live outside t/ when overridden using the
--root=<directory> option, to which the Makefile has no access. The next
best method is to grep explicitly for failed tests in the test-results/
directory, which the Makefile *can* access.
Please note that the often-recommended `prove` tool requires Perl, and
that opens a whole new can of worms on Windows. As no native Windows Perl
comes with Subversion bindings, we have to use a Perl in Git for Windows
that uses the POSIX emulation layer named MSYS2 (which is a portable
version of Cygwin). When using this emulation layer under stress, e.g.
when running massively-parallel tests, unexplicable crashes occur quite
frequently, and instead of having a solution to the original problem, the
developer now has an additional, quite huge problem. For that reason, this
developer rejected `prove` as a solution and went with this patch instead.

I am unsure about the "none" command, as I can see an initial

Consider having a submodule 'sub' and a nested submodule at 'sub/nested'.
When nested is already absorbed into sub, but sub is not absorbed into
its superproject, then we need to fixup the gitfile and core.worktree
setting for 'nested' when absorbing 'sub', but we do not need to move
its git dir around.
Previously 'nested's gitfile contained "gitdir: ../.git/modules/nested";
it has to be corrected to "gitdir: ../../.git/modules/sub1/modules/nested".
An alternative I considered to do this work lazily, i.e. when resolving
"../.git/modules/nested", we would notice the ".git" being a gitfile
linking to another path. That seemed to be robuster by design, but harder
to get the implementation right. Maybe we have to do that anyway once we
try to have submodules and worktrees working nicely together, but for now
just produce 'correct' (i.e. direct) pointers.

The recent fixes to "fsck --connectivity-only" load all of
the objects with their correct types. This keeps the
connectivity-only code path close to the regular one, but it
also introduces some unnecessary inefficiency. While getting
the type of an object is cheap compared to actually opening
and parsing the object (as the non-connectivity-only case
would do), it's still not free.
For reachable non-blob objects, we end up having to parse
them later anyway (to see what they point to), making our
type lookup here redundant.
For unreachable objects, we might never hit them at all in
the reachability traversal, making the lookup completely
wasted. And in some cases, we might have quite a few
unreachable objects (e.g., when alternates are used for
shared object storage between repositories, it's normal for
there to be objects reachable from other repositories but
not the one running fsck).
The comment in mark_object_for_connectivity() claims two
benefits to getting the type up front:
1. We need to know the types during fsck_walk(). (And not
explicitly mentioned, but we also need them when
printing the types of broken or dangling commits).
We can address this by lazy-loading the types as
necessary. Most objects never need this lazy-load at
all, because they fall into one of these categories:
a. Reachable from our tips, and are coerced into the
correct type as we traverse (e.g., a parent link
will call lookup_commit(), which converts OBJ_NONE
to OBJ_COMMIT).
b. Unreachable, but not at the tip of a chunk of
unreachable history. We only mention the tips as
"dangling", so an unreachable commit which links
to hundreds of other objects needs only report the
type of the tip commit.
2. It serves as a cross-check that the coercion in (1a) is
correct (i.e., we'll complain about a parent link that
points to a blob). But we get most of this for free
already, because right after coercing, we'll parse any
non-blob objects. So we'd notice then if we expected a
commit and got a blob.
The one exception is when we expect a blob, in which
case we never actually read the object contents.
So this is a slight weakening, but given that the whole
point of --connectivity-only is to sacrifice some data
integrity checks for speed, this seems like an
acceptable tradeoff.
Here are before and after timings for an extreme case with
~5M reachable objects and another ~12M unreachable (it's the
torvalds/linux repository on GitHub, connected to shared
storage for all of the other kernel forks):

can return NULL for some type values (like OBJ_NONE).
It's doubtful that this can be triggered in practice with
the current code, so this is probably not fixing a bug. But
it future-proofs us against modifications that make things
like OBJ_NONE more likely (and gives future patches a
central point to handle them).

In the future we want to support working tree operations within submodules,
e.g. "git checkout --recurse-submodules", which will update the submodule
to the commit as recorded in its superproject. In the submodule the
unpack-tree operation is carried out as usual, but the reporting to the
user needs to prefix any path with the superproject. The mechanism for
this is the super-prefix. (see 74866d757, git: make super-prefix option)
Add support for the super-prefix option for commands that unpack trees
by wrapping any path output in unpacking trees in the newly introduced
super_prefixed function. This new function prefixes any path with the
super-prefix if there is one. Assuming the submodule case doesn't happen
in the majority of the cases, we'd want to have a fast behavior for no
super prefix, i.e. no reallocation/copying, but just returning path.
Another aspect of introducing the `super_prefixed` function is to consider
who owns the memory and if this is the right place where the path gets
modified. As the super prefix ought to change the output behavior only and
not the actual unpack tree part, it is fine to be that late in the line.
As we get passed in 'const char *path', we cannot change the path itself,
which means in case of a super prefix we have to copy over the path.
We need two static buffers in that function as the error messages
contain at most two paths.
For testing purposes enable it in read-tree, which has no output
of paths other than an unpack-trees.c. These are all converted in
this patch.

The loose objects are created with mode 0444. That doesn't
prevent them being overwritten by rename(), but some
versions of "mv" will be extra careful and prompt the user,
even without "-i".
Reportedly macOS does this, at least in the Travis builds.
The prompt reads from /dev/null, defaulting to "no", and the
object isn't moved. Then to make matters even more
interesting, it still returns "0" and the rest of the test
proceeds, but with a broken setup.
We can work around it by using "mv -f" to override the
prompt. This should work as it's already used in t5504 for

Pass the comparison function to cmp_items() via the context parameter of
qsort_s() instead of using a global variable. That allows calling
string_list_sort() from multiple parallel threads.
Our qsort_s() in compat/ is slightly slower than qsort(1) from glibc
2.24 for sorting lots of lines:
Test HEAD^ HEAD
---------------------------------------------------------------------
0071.2: sort(1) 0.10(0.22+0.01) 0.09(0.21+0.00) -10.0%
0071.3: string_list_sort() 0.16(0.15+0.01) 0.17(0.15+0.00) +6.3%
GNU sort(1) version 8.26 is significantly faster because it uses
multiple parallel threads; with the unportable option --parallel=1 it
becomes slower:
Test HEAD^ HEAD
--------------------------------------------------------------------
0071.2: sort(1) 0.21(0.18+0.01) 0.20(0.18+0.01) -4.8%
0071.3: string_list_sort() 0.16(0.13+0.02) 0.17(0.15+0.01) +6.3%

There are two ways to create a section in a reference document (i.e.,
manpage) in DocBook 4: refsection elements and refsect, refsect2, and
refsect3 elements. Either form is acceptable as of DocBook 4.2, but
they cannot be mixed. Prior to DocBook 4.2, only the numbered forms
were acceptable.
docbook2texi only accepts the numbered forms, and this has not generally
been a problem, since AsciiDoc produces the numbered forms.
Asciidoctor, on the other hand, uses a shared backend for DocBook 4 and
5, and uses the unnumbered refsection elements instead.
If we don't convert the unnumbered form to the numbered form,
docbook2texi omits section headings, which is undesirable. Add an XSLT
stylesheet to transform the unnumbered forms to the numbered forms
automatically, and preprocess the DocBook XML as part of the
transformation to Texinfo format.
Note that this transformation is only necessary for Texinfo, since
docbook2texi provides its own stylesheets. The DocBook stylesheets,
which we use for other formats, provide the full range of DocBook 4 and
5 compatibility, and don't have this issue.

One of the really nice features of the ~/.gitconfig file is that users
can override defaults by their own preferred settings for all of their
repositories.
One such default that some users like to override is whether the
"origin" remote gets auto-pruned or not. The user would simply call
git config --global remote.origin.prune true
and from now on all "origin" remotes would be pruned automatically when
fetching into the local repository.
There is just one catch: now Git thinks that the "origin" remote is
configured, even if the repository config has no [remote "origin"]
section at all, as it does not realize that the "prune" setting was
configured globally and that there really is no "origin" remote
configured in this repository.
That is a problem e.g. when renaming a remote to a new name, when Git
may be fooled into thinking that there is already a remote of that new
name.
Let's fix this by paying more attention to *where* the remote settings
came from: if they are configured in the local repository config, we
must not overwrite them. If they were configured elsewhere, we cannot
overwrite them to begin with, as we only write the repository config.
There is only one caller of remote_is_configured() (in `git fetch`) that
may want to take remotes into account even if they were configured
outside the repository config; all other callers essentially try to
prevent the Git command from overwriting settings in the repository
config.
To accommodate that fact, the remote_is_configured() function now
requires a parameter that states whether the caller is interested in all
remotes, or only in those that were configured in the repository config.
Many thanks to Jeff King whose tireless review helped with settling for
nothing less than the current strategy.

This patch gives life to the skeleton added in the previous patch.
The motivation for converting the difftool is that Perl scripts are not at
all native on Windows, and that `git difftool` therefore is pretty slow on
that platform, when there is no good reason for it to be slow.
In addition, Perl does not really have access to Git's internals. That
means that any script will always have to jump through unnecessary
hoops, and it will often need to perform unnecessary work (e.g. when
reading the entire config every time `git config` is called to query a
single config value).
The current version of the builtin difftool does not, however, make full
use of the internals but instead chooses to spawn a couple of Git
processes, still, to make for an easier conversion. There remains a lot
of room for improvement, left later.
Note: to play it safe, the original difftool is still called unless the
config setting difftool.useBuiltin is set to true.
The reason: this new, experimental, builtin difftool was shipped as part
of Git for Windows v2.11.0, to allow for easier large-scale testing, but
of course as an opt-in feature.
The speedup is actually more noticable on Linux than on Windows: a quick
test shows that t7800-difftool.sh runs in (2.183s/0.052s/0.108s)
(real/user/sys) in a Linux VM, down from (6.529s/3.112s/0.644s), while on
Windows, it is (36.064s/2.730s/7.194s), down from (47.637s/2.407s/6.863s).
The culprit is most likely the overhead incurred from *still* having to
shell out to mergetool-lib.sh and difftool--helper.sh.
Still, it is an improvement.

Subject: clear_delta_base_cache(): don't modify hashmap while iterating
Removing entries while iterating causes fast-import to
access an already-freed `struct packed_git`, leading to
various confusing errors.
What happens is that clear_delta_base_cache() drops the
whole contents of the cache by iterating over the hashmap,
calling release_delta_base_cache() on each entry. That
function removes the item from the hashmap. The hashmap code
may then shrink the table, but the hashmap_iter struct
retains an offset from the old table.
As a result, the next call to hashmap_iter_next() may claim
that the iteration is done, even though some items haven't
been visited.
The only caller of clear_delta_base_cache() is fast-import,
which wants to clear the cache because it is discarding the
packed_git struct for its temporary pack. So by failing to
remove all of the entries, we still have references to the
freed packed_git.
To make things even more confusing, this doesn't seem to
trigger with the test suite, because it depends on
complexities like the size of the hash table, which entries
got cleared, whether we try to access them before they're
evicted from the cache, etc.
So I've been able to identify the problem with large
imports like freebsd's svn import, or a fast-export of
linux.git. But nothing that would be reasonable to run as
part of the normal test suite.
We can fix this easily by iterating over the lru linked list
instead of the hashmap. They both contain the same entries,
and we can use the "safe" variant of the list iterator,
which exists for exactly this case.
Let's also add a warning to the hashmap API documentation to
reduce the chances of getting bit by this again.

There are two spots that call lookup_object() and assume
that a non-NULL result means we have the object:
1. When we're checking the objects given to us by the user
on the command line.
2. When we're checking if a reflog entry is valid.
This generally follows fsck's mental model that we will have
looked at and loaded a "struct object" for each object in
the repository. But it misses one case: if another object
_mentioned_ an object, but we didn't actually parse it or
verify that it exists, it will still have a struct.
It's not clear if this is a triggerable bug or not.
Certainly the later parts of the reachability check need to
be careful of this, and do so by checking the HAS_OBJ flag.
But both of these steps happen before we start traversing,
so probably we won't have followed any links yet. Still,
it's easy enough to be defensive here.

Since fsck tries to continue as much as it can after seeing
an error, we still do the reachability check even if some
heads we were given on the command-line are bogus. But if
_none_ of the heads is is valid, we fallback to checking all
refs and the index, which is not what the user asked for at
all.
Instead of checking "heads", the number of successful heads
we got, check "argc" (which we know only has non-options in
it, because parse_options removed the others).

Signed-off-by: Junio C Hamano <gitster@pobox.com>
Instead of checking reachability from the refs, you can ask
fsck to check from a particular set of heads. However, the
error checking here is quite lax. In particular:
1. It claims lookup_object() will report an error, which
is not true. It only does a hash lookup, and the user
has no clue that their argument was skipped.
2. When either the name or sha1 cannot be resolved, we
continue to exit with a successful error code, even
though we didn't check what the user asked us to.
This patch fixes both of these cases.

Normally fsck makes a pass over all objects to check their
integrity, and then follows up with a reachability check to
make sure we have all of the referenced objects (and to know
which ones are dangling). The latter checks for the HAS_OBJ
flag in obj->flags to see if we found the object in the
first pass.
Commit 02976bf85 (fsck: introduce `git fsck --connectivity-only`,
2015-06-22) taught fsck to skip the initial pass, and to
fallback to has_sha1_file() instead of the HAS_OBJ check.
However, it converted only one HAS_OBJ check to use
has_sha1_file(). But there are many other places in
builtin/fsck.c that assume that the flag is set (or that
lookup_object() will return an object at all). This leads to
several bugs with --connectivity-only:
1. mark_object() will not queue objects for examination,
so recursively following links from commits to trees,
etc, did nothing. I.e., we were checking the
reachability of hardly anything at all.
2. When a set of heads is given on the command-line, we
use lookup_object() to see if they exist. But without
the initial pass, we assume nothing exists.
3. When loading reflog entries, we do a similar
lookup_object() check, and complain that the reflog is
broken if the object doesn't exist in our hash.
So in short, --connectivity-only is broken pretty badly, and
will claim that your repository is fine when it's not.
Presumably nobody noticed for a few reasons.
One is that the embedded test does not actually test the
recursive nature of the reachability check. All of the
missing objects are still in the index, and we directly
check items from the index. This patch modifies the test to
delete the index, which shows off breakage (1).
Another is that --connectivity-only just skips the initial
pass for loose objects. So on a real repository, the packed
objects were still checked correctly. But on the flipside,
it means that "git fsck --connectivity-only" still checks
the sha1 of all of the packed objects, nullifying its
original purpose of being a faster git-fsck.
And of course the final problem is that the bug only shows
up when there _is_ corruption, which is rare. So anybody
running "git fsck --connectivity-only" proactively would
assume it was being thorough, when it was not.
One possibility for fixing this is to find all of the spots
that rely on HAS_OBJ and tweak them for the connectivity-only
case. But besides the risk that we might miss a spot (and I
found three already, corresponding to the three bugs above),
there are other parts of fsck that _can't_ work without a
full list of objects. E.g., the list of dangling objects.
Instead, let's make the connectivity-only case look more
like the normal case. Rather than skip the initial pass
completely, we'll do an abbreviated one that sets up the
HAS_OBJ flag for each object, without actually loading the
object data.
That's simple and fast, and we don't have to care about the
connectivity_only flag in the rest of the code at all.
While we're at it, let's make sure we treat loose and packed
objects the same (i.e., setting up dummy objects for both
and skipping the actual sha1 check). That makes the
connectivity-only check actually fast on a real repo (40
seconds versus 180 seconds on my copy of linux.git).

After checking connectivity, fsck looks through the list of
any objects we've seen mentioned, and reports unreachable
and un-"used" ones as dangling. However, it skips any object
which is not marked as "parsed", as that is an object that
we _don't_ have (but that somebody mentioned).
Since 6e454b9a3 (clear parsed flag when we free tree
buffers, 2013-06-05), that flag can't be relied on, and the
correct method is to check the HAS_OBJ flag. The cleanup in
that commit missed this callsite, though. As a result, we
would generally fail to report dangling trees.
We never noticed because there were no tests in this area
(for trees or otherwise). Let's add some.

This test creates a multi-level set of trees, but its
cleanup routine only removes the top-level tree. After the
test finishes, the inner tree and the blob it points to
remain, making the inner tree dangling.
A later test ("cleaned up") verifies that we've removed any
cruft and "git fsck" output is clean. This passes only
because of a bug in git-fsck which fails to notice dangling
trees.
In preparation for fixing the bug, let's teach this earlier
test to clean up after itself correctly. We have to remove
the inner tree (and therefore the blob, too, which becomes
dangling after removing that tree).
Since the setup code happens inside a subshell, we can't
just set a variable for each object. However, we can stuff
all of the sha1s into the $T output variable, which is not
used for anything except cleanup.

When a loose tree or commit is read by fsck (or any git
program), unpack_sha1_rest() checks whether there is extra
cruft at the end of the object file, after the zlib data.
Blobs that are streamed, however, do not have this check.
For normal git operations, it's not a big deal. We know the
sha1 and size checked out, so we have the object bytes we
wanted. The trailing garbage doesn't affect what we're
trying to do.
But since the point of fsck is to find corruption or other
problems, it should be more thorough. This patch teaches its
loose-sha1 reader to detect extra bytes after the zlib
stream and complain.

When we iterate over the list of loose objects to check, we
get the actual path of each object. But we then throw it
away and pass just the sha1 to fsck_sha1(), which will do a
fresh lookup. Usually it would find the same object, but it
may not if an object exists both as a loose and a packed
object. We may end up checking the packed object twice, and
never look at the loose one.
In practice this isn't too terrible, because if fsck doesn't
complain, it means you have at least one good copy. But
since the point of fsck is to look for corruption, we should
be thorough.
The new read_loose_object() interface can help us get the
data from disk, and then we replace parse_object() with
parse_object_buffer(). As a bonus, our error messages now
mention the path to a corrupted object, which should make it
easier to track down errors when they do happen.

It's surprisingly hard to ask the sha1_file code to open a
_specific_ incarnation of a loose object. Most of the
functions take a sha1, and loop over the various object
types (packed versus loose) and locations (local versus
alternates) at a low level.
However, some tools like fsck need to look at a specific
file. This patch gives them a function they can use to open
the loose object at a given path.
The implementation unfortunately ends up repeating bits of
related functions, but there's not a good way around it
without some major refactoring of the whole sha1_file stack.
We need to mmap the specific file, then partially read the
zlib stream to know whether we're streaming or not, and then
finally either stream it or copy the data to a buffer.
We can do that by assembling some of the more arcane
internal sha1_file functions, but we end up having to
essentially reimplement unpack_sha1_file(), along with the
streaming bits of check_sha1_signature().
Still, most of the ugliness is contained in the new
function, and the interface is clean enough that it may be
reusable (though it seems unlikely anything but git-fsck
would care about opening a specific file).

The code paths in fsck for packed and loose objects are
quite different, and it is not immediately obvious that the
packed case behaves well. In particular:
1. The fsck_loose() function always returns "0" to tell the
iterator to keep checking more objects. Whereas
fsck_obj_buffer() (which handles packed objects)
returns -1. This is OK, because the callback machinery
for verify_pack() does not stop when it sees a non-zero
return.
2. The fsck_loose() function sets the ERROR_OBJECT bit
when fsck_obj() fails, whereas fsck_obj_buffer() sets it
only when it sees a corrupt object. This turns out not
to matter. We don't actually do anything with this bit
except exit the program with a non-zero code, and that
is handled already by the non-zero return from the
function.
So there are no bugs here, but it was certainly confusing to
me. And we do not test either of the properties in t1450
(neither that a non-corruption error will caused a non-zero
exit for a packed object, nor that we keep going after
seeing the first error). Let's test both of those
conditions, so that we'll notice if any of those assumptions
becomes invalid.

When we fail to open a corrupt loose object, we report an
error and mention the filename via sha1_file_name().
However, that function will always give us a path in the
local repository, whereas the corrupt object may have come
from an alternate. The result is a very misleading error
message.
Teach the open_sha1_file() and stat_sha1_file() helpers to
pass back the path they found, so that we can report it
correctly.
Note that the pointers we return go to static storage (e.g.,
from sha1_file_name()), which is slightly dangerous.
However, these helpers are static local helpers, and the
names are used for immediately generating error messages.
The simplicity is an acceptable tradeoff for the danger.

Commit 90cf590f5 (fsck: optionally show more helpful info
for broken links, 2016-07-17) added a remove_loose_object()
helper, but we already had a remove_object() helper that did
the same thing. Let's combine these into one.
The implementations had a few subtle differences, so I've
tried to take the best of both:
- the original used "sed", but the newer version avoids
spawning an extra process
- the original processed "$*", which was nonsense, as it
assumed only a single sha1. Use "$1" to make that more
clear.
- the newer version ran an extra rev-parse, but it was not
necessary; it's sole caller already converted the
argument into a raw sha1
- the original used "rm -f", whereas the new one uses
"rm". The latter is better because it may notice a bug
or other unexpected failure in the test. (The original
does check that the object exists before we remove it,
which is good, but that's a subset of the possible
unexpected conditions).

The 'versionsort.prereleaseSuffix' configuration variable, as its name
suggests, is supposed to only deal with tagnames with prerelease
suffixes, and allows sorting those prerelease tags in a user-defined
order before the suffixless main release tag, instead of sorting them
simply lexicographically.
However, the previous changes in this series resulted in an
interesting and useful property of version sort:
- The empty string as a configured suffix matches all tagnames,
including tagnames without any suffix, but
- tagnames containing a "real" configured suffix are still ordered
according to that real suffix, because any longer suffix takes
precedence over the empty string.
Exploiting this property we can easily generalize suffix reordering
and specify the order of tags with given suffixes not only before but
even after a main release tag by using the empty suffix to denote the
position of the main release tag, without any algorithm changes:
$ git -c versionsort.prereleaseSuffix=-alpha \
-c versionsort.prereleaseSuffix=-beta \
-c versionsort.prereleaseSuffix="" \
-c versionsort.prereleaseSuffix=-gamma \
-c versionsort.prereleaseSuffix=-delta \
tag -l --sort=version:refname 'v3.0*'
v3.0-alpha1
v3.0-beta1
v3.0
v3.0-gamma1
v3.0-delta1
Since 'versionsort.prereleaseSuffix' is not a fitting name for a
configuration variable to control this more general suffix reordering,
introduce the new variable 'versionsort.suffix'. Still keep the old
configuration variable name as a deprecated alias, though, to avoid
suddenly breaking setups already using it. Ignore the old variable if
both old and new configuration variables are set, but emit a warning
so users will be aware of it and can fix their configuration. Extend
the documentation to describe and add a test to check this more
general behavior.
Note: since the empty suffix matches all tagnames, tagnames with
suffixes not included in the configuration are listed together with
the suffixless main release tag, ordered lexicographically right after
that, i.e. before tags with suffixes listed in the configuration
following the empty suffix.

Our error() and die() calls may report messages with
arbitrary data (e.g., filenames or even data from a remote
server). Let's make it harder to cause confusion with
mischievous filenames. E.g., try:
git rev-parse "$(printf "\rfatal: this argument is too sneaky")" --
or
git rev-parse "$(printf "\x1b[5mblinky\x1b[0m")" --
Let's block all ASCII control characters, with the exception
of TAB and LF. We use both in our own messages (and we are
necessarily sanitizing the complete output of snprintf here,
as we do not have access to the individual varargs). And TAB
and LF are unlikely to cause confusion (you could put
"\nfatal: sneaky\n" in your filename, but it would at least
not _cover up_ the message leading to it, unlike "\r").
We'll replace the characters with a "?", which is similar to
how "ls" behaves. It might be nice to do something less
lossy, like converting them to "\x" hex codes. But replacing
with a single character makes it easy to do in-place and
without worrying about length limitations. This feature
should kick in rarely enough that the "?" marks are almost
never seen.
We'll leave high-bit characters as-is, as they are likely to
be UTF-8 (though there may be some Unicode mischief you
could cause, which may require further patches).

This reverts commit f4c3edc0b1.
The purpose of that commit was to let us write errors of
arbitrary length to stderr by skipping the intermediate
buffer and sending our varargs straight to fprintf. That
works, but it comes with a downside: we do not get access to
the varargs before they are sent to stderr.
On balance, it's not a good tradeoff. Error messages larger
than our 4K buffer are quite uncommon, and we've lost the
ability to make any modifications to the output (e.g., to
remove non-printable characters).
The only way to have both would be one of:
1. Write into a dynamic buffer. But this is a bad idea for
a low-level function that may be called when malloc()
has failed.
2. Do our own printf-format varargs parsing. This is too
complex to be worth the trouble.
Let's just revert that change and go back to a fixed buffer.

A few of the tests want to check that "git grep -P -E" will
override -P with -E, and vice versa. To do so, we use a
regex with "\x{..}", which is valid in PCRE but not defined
by POSIX (for basic or extended regular expressions).
However, POSIX declares quite a lot of syntax, including
"\x", as "undefined". That leaves implementations free to
extend the standard if they choose. At least one, musl libc,
implements "\x" in the same way as PCRE. Our tests check
that "-E" complains about "\x", which fails with musl.
We can fix this by finding some construct which behaves
reliably on both PCRE and POSIX, but differently in each
system.
One such construct is the use of backslash inside brackets.
In PCRE, "[\d]" interprets "\d" as it would outside the
brackets, matching a digit. Whereas in POSIX, the backslash
must be treated literally, and we match either it or a
literal "d". Moreover, implementations are not free to
change this according to POSIX, so we should be able to rely
on it.

Every once in a while someone complains to the mailing list to have
run into this weird assertion[1]. The usual response from the mailing
list is link to old discussions[2], and acknowledging the problem
stating it is known.
This patch accomplishes two things:
1. Switch assert() to die("BUG") to give a more readable message.
2. Take one of the cases where we hit a BUG and turn it into a normal
"there was something wrong with the input" message.
This assertion triggered for cases where there wasn't a programming
bug, but just bogus input. In particular, if the user asks for a
pathspec that is inside a submodule, we shouldn't assert() or
die("BUG"); we should tell the user their request is bogus.
The only reason we did not check for it, is the expensive nature
of such a check, so callers avoid setting the flag
PATHSPEC_STRIP_SUBMODULE_SLASH_EXPENSIVE. However when we die due
to bogus input, the expense of CPU cycles spent outweighs the user
wondering what went wrong, so run that check unconditionally before
dying with a more generic error message.
Note: There is a case (e.g. "git -C submodule add .") in which we call
strip_submodule_slash_expensive, as git-add requests it via the flag
PATHSPEC_STRIP_SUBMODULE_SLASH_EXPENSIVE, but the assert used to
trigger nevertheless, because the flag PATHSPEC_LITERAL was not set,
such that we executed
if (item->nowildcard_len < prefixlen)
item->nowildcard_len = prefixlen;
and prefixlen was not adapted (e.g. it was computed from "submodule/")
So in the die_inside_submodule_path function we also need handle paths,
that were stripped before, i.e. are the exact submodule path. This
is why the conditions in die_inside_submodule_path are slightly

This can happen e.g. when a fast-forward fails because it would

This is a huge patch, and at the same time a huge step forward to
execute the performance-critical parts of the interactive rebase in a
builtin command.
Since 'fixup' and 'squash' are not only similar, but also need to know
about each other (we want to reduce a series of fixups/squashes into a
single, final commit message edit, from the user's point of view), we
really have to implement them both at the same time.
Most of the actual work is done by the existing code path that already
handles the "pick" and the "edit" commands; We added support for other
features (e.g. to amend the commit message) in the patches leading up to
this one, yet there are still quite a few bits in this patch that simply
would not make sense as individual patches (such as: determining whether
there was anything to "fix up" in the "todo" script, etc).
In theory, it would be possible to reuse the fast-forward code path also
for the fixup and the squash code paths, but in practice this would make
the code less readable. The end result cannot be fast-forwarded anyway,
therefore let's just extend the cherry-picking code path for now.
Since the sequencer parses the entire `git-rebase-todo` script in one go,
fixup or squash commands without a preceding pick can be reported early
(in git-rebase--interactive, we could only report such errors just before
executing the fixup/squash).

When you hit ^C to interrupt a git command going to a pager,
this usually leaves the pager running. But when a dashed
external is in use, the pager ends up in a funny state and
quits (but only after eating one more character from the
terminal!). This fixes it.
Explaining the reason will require a little background.
When git runs a pager, it's important for the git process to
hang around and wait for the pager to finish, even though it
has no more data to feed it. This is because git spawns the
pager as a child, and thus the git process is the session
leader on the terminal. After it dies, the pager will finish
its current read from the terminal (eating the one
character), and then get EIO trying to read again.
When you hit ^C, that sends SIGINT to git and to the pager,
and it's a similar situation. The pager ignores it, but the
git process needs to hang around until the pager is done. We
addressed that long ago in a3da882120 (pager: do
wait_for_pager on signal death, 2009-01-22).
But when you have a dashed external (or an alias pointing to
a builtin, which will re-exec git for the builtin), there's
an extra process in the mix. For instance, running:
$ git -c alias.l=log l
will end up with a process tree like:
git (parent)
\
git-log (child)
\
less (pager)
If you hit ^C, SIGINT goes to all of them. The pager ignores
it, and the child git process will end up in wait_for_pager().
But the parent git process will die, and the usual EIO
trouble happens.
So we really want the parent git process to wait_for_pager(),
but of course it doesn't know anything about the pager at
all, since it was started by the child. However, we can
have it wait on the git-log child, which in turn is waiting
on the pager. And that's what this patch does.
There are a few design decisions here worth explaining:
1. The new feature is attached to run-command's
clean_on_exit feature. Partly this is convenience,
since that feature already has a signal handler that
deals with child cleanup.
But it's also a meaningful connection. The main reason
that dashed externals use clean_on_exit is to bind the
two processes together. If somebody kills the parent
with a signal, we propagate that to the child (in this
instance with SIGINT, we do propagate but it doesn't
matter because the original signal went to the whole
process group). Likewise, we do not want the parent
to go away until the child has done so.
In a traditional Unix world, we'd probably accomplish
this binding by just having the parent execve() the
child directly. But since that doesn't work on Windows,
everything goes through run_command's more spawn-like
interface.
2. We do _not_ automatically waitpid() on any
clean_on_exit children. For dashed externals this makes
sense; we know that the parent is doing nothing but
waiting for the child to exit anyway. But with other
children, it's possible that the child, after getting
the signal, could be waiting on the parent to do
something (like closing a descriptor). If we were to
wait on such a child, we'd end up in a deadlock. So
this errs on the side of caution, and lets callers
enable the feature explicitly.
3. When we send children the cleanup signal, we send all
the signals first, before waiting on any children. This
is to avoid the case where one child might be waiting
on another one to exit, causing a deadlock. We inform
all of them that it's time to die before reaping any.
In practice, there is only ever one dashed external run
from a given process, so this doesn't matter much now.
But it future-proofs us if other callers start using
the wait_after_clean mechanism.
There's no automated test here, because it would end up racy
and unportable. But it's easy to reproduce the situation by
running the log command given above and hitting ^C.

When we try to exec a git sub-command, we pass along the
status code from run_command(). But that may return -1 if we
ran into an error with pipe() or execve(). This tends to
work (and end up as 255 due to twos-complement wraparound
and truncation), but in general it's probably a good idea to
avoid negative exit codes for portability.
We can easily translate to the normal generic "128" code we
get when syscalls cause us to die.

1. We can drop all of the allocation and cleanup code for
building our custom argv array, and just rely on the
builtin argv_array (at the minor cost of doing a few
extra mallocs).
2. We have access to the complete range of child_process
options, not just the ones that the "_opt()" form can

It's possible for content currently found in one file to
have originated in two separate files, each of which may
have been modified in some single older commit. The
--porcelain output generates an incorrect "previous" header
in this case, whereas --line-porcelain gets it right. The
problem is that the porcelain output tries to omit repeated
details of commits, and treats "previous" as a property of
the commit, when it is really a property of the blamed block
of lines.
Let's look at an example. In a case like this, you might see
this output from --line-porcelain:
SOME_SHA1 1 1 1
author ...
committer ...
previous SOME_SHA1^ file_one
filename file_one
...some line content...
SOME_SHA1 2 1 1
author ...
committer ...
previous SOME_SHA1^ file_two
filename file_two
...some different content....
The "filename" fields tell us that the two lines are from
two different files. But notice that the filename also
appears in the "previous" field, which tells us where to
start a re-blame. The second content line never appeared in
file_one at all, so we would obviously need to re-blame from
file_two (or possibly even some other file, if had just been
renamed to file_two in SOME_SHA1).
So far so good. Now here's what --porcelain looks like:
SOME_SHA1 1 1 1
author ...
committer ...
previous SOME_SHA1^ file_one
filename file_one
...some line content...
SOME_SHA1 2 1 1
filename file_two
...some different content....
We've dropped the author and committer fields from the
second line, as they would just be repeats. But we can't
omit "filename", because it depends on the actual block of
blamed lines, not just the commit. This is handled by
emit_porcelain_details(), which will show the filename
either if it is the first mention of the commit _or_ if the
commit has multiple paths in it.
But we don't give "previous" the same handling. It's written
inside emit_one_suspect_detail(), which bails early if we've
already seen that commit. And so the output above is wrong;
a reader would assume that the correct place to re-blame
line two is from file_one, but that's obviously nonsense.
Let's treat "previous" the same as "filename", and show it
fresh whenever we know we are in a confusing case like this.

You can already ask blame for full sha1s with "-l" or with
"--abbrev=40". But for consistency with other parts of Git,
we should support "--no-abbrev".
Worse, blame already accepts --no-abbrev, but it's totally
broken. When we see --no-abbrev, the abbrev variable is set
to 0, which is then used as a printf precision. For regular
sha1s, that means we print nothing at all (which is very
wrong). For boundary commits we decrement it to "-1", which
printf interprets as "no limit" (which is almost correct,
except it misses the 39-length magic explained in the
previous commit).
Let's detect --no-abbrev and behave as if --abbrev=40 was
given.

The blame command internally adds 1 to any requested sha1
abbreviation length, and then subtracts it when outputting a
boundary commit. This lets regular and boundary sha1s line
up visually, but it misses one corner case.
When the requested length is 40, we bump the value to 41.
But since we only have 40 characters, that's all we can show
(fortunately the truncation is done by a printf precision
field, so it never tries to read past the end of the
buffer). So a normal sha1 shows 40 hex characters, and a
boundary sha1 shows "^" plus 40 hex characters. The result
is misaligned.
The "-l" option to show long sha1s gets around this by
skipping the "abbrev" variable entirely and just always
using GIT_SHA1_HEXSZ. This avoids the "+1" issue, but it
does mean that boundary commits only have 39 characters
printed. This is somewhat odd, but it does look good
visually: the results are aligned and left-justified. The
alternative would be to allocate an extra column that would
contain either an extra space or the "^" boundary marker.
As this is by definition the human-readable view, it's
probably not that big a deal either way (and of course
--porcelain, etc, correctly produce correct 40-hex sha1s).
But for consistency, this patch teaches --abbrev=40 to
produce the same output as "-l" (always left-aligned, with
40-hex for normal sha1s, and "^" plus 39-hex for
boundaries).

We generate the squash commit message incrementally running
a sed script once for each commit. It parses "This is
a combination of <N> commits" from the first line of the
existing message, adds one to <N>, and uses the result as
the number of our current message.
Since f2d17068fd (i18n: rebase-interactive: mark comments of
squash for translation, 2016-06-17), the first line may be
localized, and sed uses a pretty liberal regex, looking for:
/^#.*([0-9][0-9]*)/
The "[0-9][0-9]*" tries to match double digits, but it
doesn't quite work. The first ".*" is greedy, so if you
have:
This is a combination of 10 commits.
it will eat up "This is a combination of 1", leaving "0" to
match the first "[0-9]" digit, and then skipping the
optional match of "[0-9]*".
As a result, the count resets every 10 commits, and a
15-commit squash would end up as:
# This is a combination of 5 commits.
# This is the 1st commit message:
...
# This is the commit message #2:
... and so on ..
# This is the commit message #10:
...
# This is the commit message #1:
...
# This is the commit message #2:
... etc, up to 5 ...
We can fix this by making the ".*" less greedy. Instead of
depending on ".*?" working portably, we can just limit the
match to non-digit characters, which accomplishes the same
thing.

The "giteveryday" document has a callout list that contains a code

an unhelpful

In Git for Windows, we rely on the speed improvement of AsciiDoctor (on

On Windows, there are "UNC paths" to access network (AKA shared)
folders, of the form \\server\sharename\directory. This provides a
convenient way for Windows developers to share their Git repositories
without having to have a dedicated server.
Git for Windows v2.11.0 introduced a regression where pushing to said
UNC paths no longer works, although fetching and cloning still does, as
reported here: https://github.com/git-for-windows/git/issues/979
This regression was fixed in 7814fbe3f1 (normalize_path_copy(): fix
pushing to //server/share/dir on Windows, 2016-12-14).
Let's make sure that it does not regress again, by introducing a test
that uses so-called "administrative shares": disk volumes are
automatically shared under certain circumstances, e.g. the C: drive is
shared as \\localhost\c$. The test needs to be skipped if the current
directory is inaccessible via said administrative share, of course.

When deleting a submodule, we need to keep the actual git directory around,
such that we do not lose local changes in there and at a later checkout
of the submodule we don't need to clone it again.
Now that the functionality is available to absorb the git directory of a
submodule, rewrite the checking in git-rm to not complain, but rather
relocate the git directories inside the superproject.
An alternative solution was discussed to have a function
`depopulate_submodule`. That would couple the check for its git directory
and possible relocation before the the removal, such that it is less
likely to miss the check in the future. But the indirection with such
a function added seemed also complex. The reason for that was that this
possible move of the git directory was also implemented in
`ok_to_remove_submodule`, such that this function could truthfully
answer whether it is ok to remove the submodule.
The solution proposed here defers all these checks to the caller.

In different contexts the question "Is it ok to delete a submodule?"
may be answered differently.
In 293ab15eea (submodule: teach rm to remove submodules unless they
contain a git directory, 2012-09-26) a case was made that we can safely
ignore ignored untracked files for removal as we explicitely ask for the
removal of the submodule.
In a later patch we want to remove submodules even when the user doesn't
explicitly ask for it (e.g. checking out a tree-ish in which the submodule
doesn't exist). In that case we want to be more careful when it comes
to deletion of untracked files. As of this patch it is unclear how this
will be implemented exactly, so we'll offer flags in which the caller
can specify how the different untracked files ought to be handled.
As the flags allow the function to not die on an error when spawning
a child process, we need to find an appropriate return code for the
case when the child process could not be started. As in that case we
cannot tell if the submodule is ok to remove, we'd want to return 'false'.
As only 0 is understood as false, rename the function to invert the
meaning, i.e. the return code of 0 signals the removal of the submodule
is fine, and other values can be used to return a more precise answer
what went wrong.

If a submodule was renamed at any point since it's inception then if you
were to try and grep on a commit prior to the submodule being moved, you
wouldn't be able to find a working directory for the submodule since the
path in the past is different from the current path.
This patch teaches grep to find the .git directory for a submodule in
the parents .git/modules/ directory in the event the path to the
submodule in the commit that is being searched differs from the state of
the currently checked out commit. If found, the child process that is
spawned to grep the submodule will chdir into its gitdir instead of a
working directory.
In order to override the explicit setting of submodule child process's
gitdir environment variable (which was introduced in '10f5c526')
`GIT_DIR_ENVIORMENT` needs to be pushed onto child process's env_array.
This allows the searching of history from a submodule's gitdir, rather
than from a working directory.

Recursion only occurs for submodules which have been initialized and

In order to support the existing multi-threading infrastructure in grep,
output from each child process is captured in a strbuf so that it can be
later printed to the console in an ordered fashion.

have a pathname with a colon in it (no surprise!), and this in turn
made it impossible to push into a repository at such a path. This
has been fixed by introducing a quoting mechanism used when
appending such a path to the colon-separated list.

In typical uses of fast-import, trees are inherited from a parent
commit. In that case, the tree_entry for the branch looks like:
.versions[1].sha1 = $some_sha1
.tree = <tree structure loaded from $some_sha1>
However, when trees are imported, rather than inherited, that is not the
case. One can import a tree with a filemodify command, replacing the
root tree object.
e.g.
"M 040000 $some_sha1 \n"
In this case, the tree_entry for the branch looks like:
.versions[1].sha1 = $some_sha1
.tree = NULL
When adding new notes with the notemodify command, do_change_note_fanout
is called to get a notes count, and to do so, it loops over the
tree_entry->tree, but doesn't do anything when the tree is NULL.
In the latter case above, it means do_change_note_fanout thinks the tree
contains no notes, and new notes are added with no fanout.
Interestingly, do_change_note_fanout does check whether subdirectories
have a NULL .tree, in which case it uses load_tree(). Which means the
right behaviour happens when using the filemodify command to import
subdirectories.
This change makes do_change_note_fanount call load_tree() whenever the
tree_entry it is given has no tree loaded, making all cases handled
equally.

Teach push the --recurse-submodules=only option. This enables push
to recursively push all unpushed submodules while leaving the
superproject unpushed.
This is a desirable feature in a scenario where updates to the
superproject are handled automatically by some other means, perhaps
a tool like Gerrit code review. In this scenario, a developer could
make a change which spans multiple submodules and then push their
commits for code review. Upon completion of the code review, their
commits can be accepted and applied to their respective submodules
while the code review tool can then automatically update the
superproject to the most recent SHA1 of each submodule. This would
reduce the merge conflicts in the superproject that could occur if
multiple people are contributing to the same submodule.

Since 6b4b013f18 (mailinfo: handle in-body header continuations,
2016-09-20, v2.11.0) mailinfo.c has contained new code with an
assert of the form:
assert(call_a_function(...))
The function in question, check_header, has side effects. This
means that when NDEBUG is defined during a release build the
function call is omitted entirely, the side effects do not
take place and tests (fortunately) start failing.
Since the only time that mi->inbody_header_accum is appended to is
in check_inbody_header, and appending onto a blank
mi->inbody_header_accum always happens when is_inbody_header is
true, this guarantees a prefix that causes check_header to always
return true.
Therefore replace the assert with an if !check_header + DIE
combination to reflect this.

When importing from multiple perforce paths - we may attempt to
import a changelist that contains files from two (or more) of these
depot paths. Currently, this results in multiple git commits - one
containing the changes, and the other(s) as empty commit(s). This
behavior was introduced in commit 1f90a64891 ("git-p4: reduce number
of server queries for fetches", 2015-12-19).
Reproduction Steps:
1. Have a git repo cloned from a perforce repo using multiple
depot paths (e.g. //depot/foo and //depot/bar).
2. Submit a single change to the perforce repo that makes changes
in both //depot/foo and //depot/bar.
3. Run "git p4 sync" to sync the change from #2.
Change is synced as multiple commits, one for each depot path that
was affected.
Using a set, instead of a list inside p4ChangesForPaths() ensures
that each changelist is unique to the returned list, and therefore
only a single commit is generated for each changelist.

normalize_path_copy() is not prepared to keep the double-slash of a

style path and transforms it to /server/share/dir.
The bug manifests when 'git push //server/share/dir master' is run,
because tmp_objdir_add_as_alternate() uses the path in normalized
form when it registers the quarantine object database via
link_alt_odb_entries(). Needless to say that the directory cannot be
accessed using the wrongly normalized path.

The http-walker may fetch the http-alternates (or
alternates) file from a remote in order to find more
objects. This should count as a "not from the user" use of
the protocol. But because we implement the redirection
ourselves and feed the new URL to curl, it will use the
CURLOPT_PROTOCOLS rules, not the more restrictive
CURLOPT_REDIR_PROTOCOLS.
The ideal solution would be for each curl request we make to
know whether or not is directly from the user or part of an
alternates redirect, and then set CURLOPT_PROTOCOLS as
appropriate. However, that would require plumbing that
information through all of the various layers of the http
code.
Instead, let's check the protocol at the source: when we are
parsing the remote http-alternates file. The only downside
is that if there's any mismatch between what protocol we
think it is versus what curl thinks it is, it could violate
the policy.
To address this, we'll make the parsing err on the picky
side, and only allow protocols that it can parse
definitively. So for example, you can't elude the "http"
policy by asking for "HTTP://", even though curl might
handle it; we would reject it as unknown. The only unsafe
case would be if you have a URL that starts with "http://"
but curl interprets as another protocol. That seems like an
unlikely failure mode (and we are still protected by our
base CURLOPT_PROTOCOL setting, so the worst you could do is
trigger one of https, ftp, or ftps).

Add a from_user parameter to is_transport_allowed() to allow http to be
able to distinguish between protocol restrictions for redirects versus
initial requests. CURLOPT_REDIR_PROTOCOLS can now be set differently
from CURLOPT_PROTOCOLS to disallow use of protocols with the "user"
policy in redirects.
This change allows callers to query if a transport protocol is allowed,
given that the caller knows that the protocol is coming from the user
(1) or not from the user (0) such as redirects in libcurl. If unknown a
-1 should be provided which falls back to reading

Previously the `GIT_ALLOW_PROTOCOL` environment variable was used to
specify a whitelist of protocols to be used in clone/fetch/push
commands. This patch introduces new configuration options for more
fine-grained control for allowing/disallowing protocols. This also has
the added benefit of allowing easier construction of a protocol
whitelist on systems where setting an environment variable is
non-trivial.
Now users can specify a policy to be used for each type of protocol via
the 'protocol.<name>.allow' config option. A default policy for all
unconfigured protocols can be set with the 'protocol.allow' config
option. If no user configured default is made git will allow known-safe
protocols (http, https, git, ssh, file), disallow known-dangerous
protocols (ext), and have a default policy of `user` for all other
protocols.
The supported policies are `always`, `never`, and `user`. The `user`
policy can be used to configure a protocol to be usable when explicitly
used by a user, while disallowing it for commands which run
clone/fetch/push commands without direct user intervention (e.g.
recursive initialization of submodules). Commands which can potentially
clone/fetch/push from untrusted repositories without user intervention
can export `GIT_PROTOCOL_FROM_USER` with a value of '0' to prevent
protocols configured to the `user` policy from being used.
Fix remote-ext tests to use the new config to allow the ext
protocol to be tested.

The newly added code in this patch is structured such that other areas of

`absorb_git_dir_into_superproject`, that takes care of embedding the
submodules git directory into the superprojects git dir. That function

In a later patch we want to move around the the git directory of
a submodule. Both submodules as well as worktrees are involved in
placing git directories at unusual places, so their functionality
may collide. To react appropriately to situations where worktrees
in submodules are in use, offer a new function to query the
a submodule if it uses the worktree feature.
An earlier approach:
"Implement submodule_get_worktrees and just count them", however:
This can be done cheaply (both in new code to write as well as run time)
by obtaining the list of worktrees based off that submodules git
directory. However as we have loaded the variables for the current
repository, the values in the submodule worktree
can be wrong, e.g.
* core.ignorecase may differ between these two repositories
* the ref resolution is broken (refs/heads/branch in the submodule
resolves to the sha1 value of the `branch` in the current repository
that may not exist or have another sha1)
The implementation here is just checking for any files in
$GIT_COMMON_DIR/worktrees for the submodule, which ought to be sufficient
if the submodule is using the current repository format, which we also
check.

Commit 722ff7f87 (receive-pack: quarantine objects until
pre-receive accepts, 2016-10-03) regressed pushes to
repositories with colon (or semi-colon in Windows in them)
because it adds the repository's main object directory to
GIT_ALTERNATE_OBJECT_DIRECTORIES. The receiver interprets
the colon as a delimiter, not as part of the path, and
index-pack is unable to find objects which it needs to
resolve deltas.
The previous commit introduced a quoting mechanism for the
alternates list; let's use it here to cover this case. We'll
avoid quoting when we can, though. This alternate setup is
also used when calling hooks, so it's possible that the user
may call older git implementations which don't understand
the quoting mechanism. By quoting only when necessary, this
setup will continue to work unless the user _also_ has a
repository whose path contains the delimiter.
Signed-off-by: Jeff King <peff@peff.net>
Signed-off-by: Junio C Hamano <gitster@pobox.com>
We read lists of alternates from objects/info/alternates
files (delimited by newline), as well as from the
GIT_ALTERNATE_OBJECT_DIRECTORIES environment variable
(delimited by colon or semi-colon, depending on the
platform).
There's no mechanism for quoting the delimiters, so it's
impossible to specify an alternate path that contains a
colon in the environment, or one that contains a newline in
a file. We've lived with that restriction for ages because
both alternates and filenames with colons are relatively
rare, and it's only a problem when the two meet. But since
722ff7f87 (receive-pack: quarantine objects until
pre-receive accepts, 2016-10-03), which builds on the
alternates system, every push causes the receiver to set
GIT_ALTERNATE_OBJECT_DIRECTORIES internally.
It would be convenient to have some way to quote the
delimiter so that we can represent arbitrary paths.
The simplest thing would be an escape character before a
quoted delimiter (e.g., "\:" as a literal colon). But that
creates a backwards compatibility problem: any path which
uses that escape character is now broken, and we've just
shifted the problem. We could choose an unlikely escape
character (e.g., something from the non-printable ASCII
range), but that's awkward to use.
Instead, let's treat names as unquoted unless they begin
with a double-quote, in which case they are interpreted via
our usual C-stylke quoting rules. This also breaks
backwards-compatibility, but in a smaller way: it only
matters if your file has a double-quote as the very _first_
character in the path (whereas an escape character is a
problem anywhere in the path). It's also consistent with
many other parts of git, which accept either a bare pathname
or a double-quoted one, and the sender can choose to quote
or not as required.

- Have a Tcl version with memory debugging enabled. This is,
build one with --enable-symbols=mem passed to configure.
- Instrument Gitk to regularly show a memory dump. E.g. by adding
these code lines at the very bottom:
proc memDump {} {
catch {
set output [memory info]
puts $output
}
after 3000 memDump
}
memDump
- Start Gitk, it'll load this largish commit into the diff text
field automatically (because it's the current commit).
- Wait until memory consumption levels out and note the numbers.
Note that the numbers reported by [memory info] are much smaller
than the ones reported in 'top' (1.75 GB vs. 105 MB in this case),

it introduced a regression in how entries outside of the

When preparing the right-side of the diff we only include the

The left side of the diff is constructed from a temporary
index that is built from the same set of changed files, but it
was being constructed from within the subdirectory. This is a
problem because the indexed paths are toplevel-relative, and
thus they were not getting added to the index.

When Git's source code calls isatty(), it really asks whether the
respective file descriptor is connected to an interactive terminal.
Windows' _isatty() function, however, determines whether the file
descriptor is associated with a character device. And NUL, Windows'
equivalent of /dev/null, is a character device.
Which means that for years, Git mistakenly detected an associated
interactive terminal when being run through the test suite, which
almost always redirects stdin, stdout and stderr to /dev/null.
This bug only became obvious, and painfully so, when the new
bisect--helper entered the `pu` branch and made the automatic build & test
time out because t6030 was waiting for an answer.

it's already too late to retrace your steps. The solution is normally
rm -r .git/<some rebase dir>
and continue with your life. But there could be two different
directories for <some rebase dir> (and it obviously requires some
knowledge of how rebase works), and the ".git" part could be much
longer if you are not at top-dir, or in a linked worktree. And
"rm -r" is very dangerous to do in .git, a mistake in there could

By adding the word "just", which might have been accidentally omitted.
Adding the word "just" makes it clear that the point is to *not* do an
octopus merge simply because you *can* do it. In other words, you
should have a reason for doing it beyond simply having two (seemingly)
independent commits that you need to merge into another branch, since
it's not always the best approach.
The previous sentence made it look more like it was trying to say that
you shouldn't do an octopus merge *because* you can do an octopus merge.
Although this interpretation doesn't make sense and the rest of the
paragraph makes the intended meaning clear, this adjustment should make
the intent of the sentence more immediately clear to the reader.

In contrast to "git am --abort", a sequencer abort did not check
whether the current HEAD is the one that is expected. This can lead
to loss of work (when not spotted and resolved using reflog before
the garbage collector chimes in).
This behavior is now changed by mimicking "git am --abort". The
abortion is done but HEAD is not changed when the current HEAD is
not the expected HEAD.
A new file "sequencer/abort-safety" is added to save the expected
HEAD.
The new behavior is only active when --abort is invoked on multiple

There are two different places where the --no-abbrev option is parsed,
and two different places where SHA-1s are abbreviated. We normally parse
--no-abbrev with setup_revisions(), but in the no-index case, "git diff"
calls diff_opt_parse() directly, and diff_opt_parse() didn't handle
--no-abbrev until now. (It did handle --abbrev, however.) We normally
abbreviate SHA-1s with find_unique_abbrev(), but commit 4f03666 ("diff:
handle sha1 abbreviations outside of repository, 2016-10-20) recently
introduced a special case when you run "git diff" outside of a
repository.
setup_revisions() does also call diff_opt_parse(), but not for --abbrev
or --no-abbrev, which it handles itself. setup_revisions() sets
rev_info->abbrev, and later copies that to diff_options->abbrev. It
handles --no-abbrev by setting abbrev to zero. (This change doesn't
touch that.)
Setting abbrev to zero was broken in the outside-of-a-repository special
case, which until now resulted in a truly zero-length SHA-1, rather than
taking zero to mean do not abbreviate. The only way to trigger this bug,
however, was by running "git diff --raw" without either the --abbrev or
--no-abbrev options, because 1) without --raw it doesn't respect abbrev
(which is bizarre, but has been that way forever), 2) we silently clamp
--abbrev=0 to MINIMUM_ABBREV, and 3) --no-abbrev wasn't handled until
now.
The outside-of-a-repository case is one of three no-index cases. The
other two are when one of the files you're comparing is outside of the
repository you're in, and the --no-index option.

When comparing tagnames, it is possible that a tagname contains more
than one of the configured prerelease suffixes around the first
different character. After fixing a bug in the previous commit such a
tagname is sorted according to the contained suffix which comes first
in the configuration. This is, however, not quite the right thing to
do in the following corner cases:
1. $ git -c versionsort.suffix=-bar
-c versionsort.suffix=-foo-baz
-c versionsort.suffix=-foo-bar
tag -l --sort=version:refname 'v1*'
v1.0-foo-bar
v1.0-foo-baz
The suffix of the tagname 'v1.0-foo-bar' is clearly '-foo-bar',
so it should be listed last. However, as it also contains '-bar'
around the first different character, it is listed first instead,
because that '-bar' suffix comes first the configuration.
2. One of the configured suffixes starts with the other:
$ git -c versionsort.prereleasesuffix=-pre \
-c versionsort.prereleasesuffix=-prerelease \
tag -l --sort=version:refname 'v2*'
v2.0-prerelease1
v2.0-pre1
v2.0-pre2
Here the tagname 'v2.0-prerelease1' should be the last. When
comparing 'v2.0-pre1' and 'v2.0-prerelease1' the first different
characters are '1' and 'r', respectively. Since this first
different character must be part of the configured suffix, the
'-pre' suffix is not recognized in the first tagname. OTOH, the
'-prerelease' suffix is properly recognized in
'v2.0-prerelease1', thus it is listed first.
Improve version sort in these corner cases, and
- look for a configured prerelease suffix containing the first
different character or ending right before it, so the '-pre'
suffixes are recognized in case (2). This also means that
when comparing tagnames 'v2.0-pre1' and 'v2.0-pre2',
swap_prereleases() would find the '-pre' suffix in both, but then
it will return "undecided" and the caller will do the right thing
by sorting based in '1' and '2'.
- If the tagname contains more than one suffix, then give precedence
to the contained suffix that starts at the earliest offset in the
tagname to address (1).
- If there are more than one suffixes starting at that earliest
position, then give precedence to the longest of those suffixes,
thus ensuring that in (2) the tagname 'v2.0-prerelease1' won't be
sorted based on the '-pre' suffix.
Add tests for these corner cases and adjust the documentation
accordingly.

Version sort with prerelease reordering sometimes puts tagnames in the
wrong order, when the common part of two compared tagnames overlaps
with the leading character(s) of one or more configured prerelease
suffixes. Note the position of "v2.1.0-beta-1":
$ git -c versionsort.prereleaseSuffix=-beta \
tag -l --sort=version:refname v2.1.*
v2.1.0-beta-2
v2.1.0-beta-3
v2.1.0
v2.1.0-RC1
v2.1.0-RC2
v2.1.0-beta-1
v2.1.1
v2.1.2
The reason is that when comparing a pair of tagnames, first
versioncmp() looks for the first different character in a pair of
tagnames, and then the swap_prereleases() helper function looks for a
configured prerelease suffix _starting at_ that character. Thus, when
in the above example the sorting algorithm happens to compare the
tagnames "v2.1.0-beta-1" and "v2.1.0-RC2", swap_prereleases() tries to
match the suffix "-beta" against "beta-1" to no avail, and the two
tagnames erroneously end up being ordered lexicographically.
To fix this issue change swap_prereleases() to look for configured
prerelease suffixes _containing_ the position of that first different
character.
Care must be taken, when a configured suffix is longer than the
tagnames' common part up to the first different character, to avoid
reading memory before the beginning of the tagnames. Add a test that
uses an exceptionally long prerelease suffix to check for this, in the
hope that in case of a regression the illegal memory access causes a
segfault in 'git tag' on one of the commonly used platforms (the test
happens to pass successfully on my Linux system with the safety check
removed), or at least makes valgrind complain.
Under some circumstances it's possible that more than one prerelease
suffixes can be found in the same tagname around that first different
character. With this simple bugfix patch such a tagname is sorted
according to the contained suffix that comes first in the
configuration for now. This is less than ideal in some cases, and the
following patch will take care of those.

corrected how path arguments are handled in a subdirectory, but
it introduced a regression in how entries outside of the

When preparing the right-side of the diff we only include the
changed paths in the temporary area.
The left side of the diff is constructed from a temporary
index that is built from the same set of changed files, but it
was being constructed from within the subdirectory. This is a
problem because the indexed paths are toplevel-relative, and
thus they were not getting added to the index.
Teach difftool to chdir to the toplevel of the repository before
preparing its temporary indexes. This ensures that all of the
toplevel-relative paths are valid.

Some context before we talk about the removed code.
This paint_down() is part of step 6 of 58babff (shallow.c: the 8 steps
to select new commits for .git/shallow - 2013-12-05). When we fetch from
a shallow repository, we need to know if one of the new/updated refs
needs new "shallow commits" in .git/shallow (because we don't have
enough history of those refs) and which one.
The question at step 6 is, what (new) shallow commits are required in
other to maintain reachability throughout the repository _without_
cutting our history short? To answer, we mark all commits reachable from
existing refs with UNINTERESTING ("rev-list --not --all"), mark shallow
commits with BOTTOM, then for each new/updated refs, walk through the
commit graph until we either hit UNINTERESTING or BOTTOM, marking the
ref on the commit as we walk.
After all the walking is done, we check the new shallow commits. If we
have not seen any new ref marked on a new shallow commit, we know all
new/updated refs are reachable using just our history and .git/shallow.
The shallow commit in question is not needed and can be thrown away.
So, the code.
The loop here (to walk through commits) is basically
1. get one commit from the queue
2. ignore if it's SEEN or UNINTERESTING
3. mark it
4. go through all the parents and..
5a. mark it if it's never marked before
5b. put it back in the queue
What we do in this patch is drop step 5a because it is not
necessary. The commit being marked at 5a is put back on the queue, and
will be marked at step 3 at the next iteration. The only case it will
not be marked is when the commit is already marked UNINTERESTING (5a
does not check this), which will be ignored at step 2.
But we don't care about refs marking on UNINTERESTING. We care about the
marking on _shallow commits_ that are not reachable from our current
history (and having UNINTERESTING on it means it's reachable). So it's
ok for an UNINTERESTING not to be ref-marked.

First of all, 1 << 31 is technically undefined behaviour, so let's just
use an unsigned literal.
If i is 'signed int' and gcc doesn't know that i is positive, gcc
generates code to compute the C99-mandated values of "i / 32" and "i %
32", which is a lot more complicated than simple a simple shifts/mask.
The only caller of paint_down actually passes an "unsigned int" value,
but the prototype of paint_down causes (completely well-defined)
conversion to signed int, and gcc has no way of knowing that the
converted value is non-negative. Just make the id parameter unsigned.
In update_refstatus, the change in generated code is much smaller,
presumably because gcc is smart enough to see that i starts as 0 and is
only incremented, so it is allowed (per the UD of signed overflow) to
assume that i is always non-negative. But let's just help less smart
compilers generate good code anyway.

paint_alloc() allocates a big block of memory and splits it into
smaller, fixed size, chunks of memory whenever it's called. Each chunk
contains enough bits to present all "new refs" [1] in a fetch from a
shallow repository.
We do not check if the new "big block" is smaller than the requested
memory chunk though. If it happens, we'll happily pass back a memory
region smaller than expected. Which will lead to problems eventually.
A normal fetch may add/update a dozen new refs. Let's stay on the
"reasonably extreme" side and say we need 16k refs (or bits from
paint_alloc's perspective). Each chunk of memory would be 2k, much
smaller than the memory pool (512k).
So, normally, the under-allocation situation should never happen. A bad
guy, however, could make a fetch that adds more than 4m new/updated refs
to this code which results in a memory chunk larger than pool size.
Check this case and abort.

progress.
The command still exits with a non-zero status, but that is not of
much help for an interactive user. The last thing the command says
is "Updating $from..$to". We used to follow it with a big error

What is sad is that we should have noticed this regression while
reviewing the change. It was clear that the update to the
checkout_fast_forward() function made a failing hold_locked_index()
silent, but the only caller of the checkout_fast_forward() function
had this comment:
if (checkout_fast_forward(from, to, 1))

+ return -1; /* the callee should have complained already */
which clearly contradicted the assumption X-<.

LOCK_DIE_ON_ERROR to the hold_lock*() family of functions and teach

that used to pass LOCK_DIE_ON_ERROR but were modified to pass 0 in

it appears that this is the only one that has become silent. Many
others used to give detailed report that talked about "there may be

Among the callers of hold_locked_index() that passes 0:

just before the program exits and nobody should care.
- builtin/describe.c::cmd_describe(),
builtin/commit.c::cmd_status(),
sequencer.c::read_and_refresh_cache() are all opportunistic
updates and they are OK.
- builtin/update-index.c::cmd_update_index() takes a lock upfront
but we may end up not needing to update the index (i.e. the
entries may be fully up-to-date), in which case we do not need to
issue an error upon failure to acquire the lock. We do diagnose
and die if we indeed need to update, so it is OK.
- wt-status.c::require_clean_work_tree() IS BUGGY. It asks
silence, does not check the returned value. Compare with
callsites like cmd_describe() and cmd_status() to notice that it
is wrong to call update_index_if_able() unconditionally.
The require_clean_work_tree() function calls hold_locked_index()
with die_on_error=0 to signal that it is OK if it fails to obtain
the lock, but unconditionally calls update_index_if_able(), which

When creating a stash, we need to look at the diff between

renames by default, this causes at least one problem. The
--name-only format will not mention the source side of a

We could fix that case by passing --no-renames, but this is

The xdiff code hashes every line of both sides of a diff,
and then compares those hashes to find duplicates. The
overall performance depends both on how fast we can compute
the hashes, but also on how many hash collisions we see.
The idea of XDL_FAST_HASH is to speed up the hash
computation. But the generated hashes have worse collision
behavior. This means that in some cases it speeds diffs up
(running "git log -p" on git.git improves by ~8% with it),
but in others it can slow things down. One pathological case
saw over a 100x slowdown[1].
There may be a better hash function that covers both
properties, but in the meantime we are better off with the
original hash. It's slightly slower in the common case, but
it has fewer surprising pathological cases.

Since commit 17966c0a6 (http: avoid disconnecting on 404s
for loose objects, 2016-07-11), we turn off curl's
FAILONERROR option and instead manually deal with failing
HTTP codes.
However, the logic to do so only recognizes HTTP 404 as a
failure. This is probably the most common result, but if we
were to get another code, the curl result remains CURLE_OK,
and we treat it as success. We still end up detecting the
failure when we try to zlib-inflate the object (which will
fail), but instead of reporting the HTTP error, we just
claim that the object is corrupt.
Instead, let's catch anything in the 300's or above as an
error (300's are redirects which are not an error at the
HTTP level, but are an indication that we've explicitly
disabled redirects, so we should treat them as such; we
certainly don't have the resulting object content).
Note that we also fill in req->errorstr, which we didn't do
before. Without FAILONERROR, curl will not have filled this
in, and it will remain a blank string. This never mattered
for the 404 case, because in the logic below we hit the
"missing_target()" branch and print nothing. But for other
errors, we'd want to say _something_, if only to fill in the
blank slot in the error message.

The previous commit made HTTP redirects more obvious and
tightened up the default behavior. However, there's another
way for a server to ask a git client to fetch arbitrary
content: by having an http-alternates file (or a regular
alternates file, which is used as a backup).
Similar to the HTTP redirect case, a malicious server can
claim to have refs pointing at object X, return a 404 when
the client asks for X, but point to some other URL via
http-alternates, which the client will transparently fetch.
The end result is that it looks from the user's perspective
like the objects came from the malicious server, as the
other URL is not mentioned at all.
Worse, because we feed the new URL to curl ourselves, the
usual protocol restrictions do not kick in (neither curl's
default of disallowing file://, nor the protocol
whitelisting in f4113cac0 (http: limit redirection to
protocol-whitelist, 2015-09-22).
Let's apply the same rules here as we do for HTTP redirects.
Namely:
- unless http.followRedirects is set to "always", we will
not follow remote redirects from http-alternates (or
alternates) at all
- set CURLOPT_PROTOCOLS alongside CURLOPT_REDIR_PROTOCOLS
restrict ourselves to a known-safe set and respect any
user-provided whitelist.
- mention alternate object stores on stderr so that the
user is aware another source of objects may be involved
The first item may prove to be too restrictive. The most
common use of alternates is to point to another path on the
same server. While it's possible for a single-server
redirect to be an attack, it takes a fairly obscure setup
(victim and evil repository on the same host, host speaks
dumb http, and evil repository has access to edit its own
http-alternates file).
So we could make the checks more specific, and only cover
cross-server redirects. But that means parsing the URLs
ourselves, rather than letting curl handle them. This patch
goes for the simpler approach. Given that they are only used
with dumb http, http-alternates are probably pretty rare.
And there's an escape hatch: the user can allow redirects on
a specific server by setting http.<url>.followRedirects to
"always".

We instruct curl to always follow HTTP redirects. This is
convenient, but it creates opportunities for malicious
servers to create confusing situations. For instance,
imagine Alice is a git user with access to a private
repository on Bob's server. Mallory runs her own server and
wants to access objects from Bob's repository.
Mallory may try a few tricks that involve asking Alice to
clone from her, build on top, and then push the result:
1. Mallory may simply redirect all fetch requests to Bob's
server. Git will transparently follow those redirects
and fetch Bob's history, which Alice may believe she
got from Mallory. The subsequent push seems like it is
just feeding Mallory back her own objects, but is
actually leaking Bob's objects. There is nothing in
git's output to indicate that Bob's repository was
involved at all.
The downside (for Mallory) of this attack is that Alice
will have received Bob's entire repository, and is
likely to notice that when building on top of it.
2. If Mallory happens to know the sha1 of some object X in
Bob's repository, she can instead build her own history
that references that object. She then runs a dumb http
server, and Alice's client will fetch each object
individually. When it asks for X, Mallory redirects her
to Bob's server. The end result is that Alice obtains
objects from Bob, but they may be buried deep in
history. Alice is less likely to notice.
Both of these attacks are fairly hard to pull off. There's a
social component in getting Mallory to convince Alice to
work with her. Alice may be prompted for credentials in
accessing Bob's repository (but not always, if she is using
a credential helper that caches). Attack (1) requires a
certain amount of obliviousness on Alice's part while making
a new commit. Attack (2) requires that Mallory knows a sha1
in Bob's repository, that Bob's server supports dumb http,
and that the object in question is loose on Bob's server.
But we can probably make things a bit more obvious without
any loss of functionality. This patch does two things to
that end.
First, when we encounter a whole-repo redirect during the
initial ref discovery, we now inform the user on stderr,
making attack (1) much more obvious.
Second, the decision to follow redirects is now
configurable. The truly paranoid can set the new
http.followRedirects to false to avoid any redirection
entirely. But for a more practical default, we will disallow
redirects only after the initial ref discovery. This is
enough to thwart attacks similar to (2), while still
allowing the common use of redirects at the repository
level. Since c93c92f30 (http: update base URLs when we see
redirects, 2013-09-28) we re-root all further requests from
the redirect destination, which should generally mean that
no further redirection is necessary.
As an escape hatch, in case there really is a server that
needs to redirect individual requests, the user can set
http.followRedirects to "true" (and this can be done on a
per-server basis via http.*.followRedirects config).

If a malicious server redirects the initial ref
advertisement, it may be able to leak sha1s from other,
unrelated servers that the client has access to. For
example, imagine that Alice is a git user, she has access to
a private repository on a server hosted by Bob, and Mallory
runs a malicious server and wants to find out about Bob's
private repository.
Mallory asks Alice to clone an unrelated repository from her
over HTTP. When Alice's client contacts Mallory's server for
the initial ref advertisement, the server issues an HTTP
redirect for Bob's server. Alice contacts Bob's server and
gets the ref advertisement for the private repository. If
there is anything to fetch, she then follows up by asking
the server for one or more sha1 objects. But who is the
server?
If it is still Mallory's server, then Alice will leak the
existence of those sha1s to her.
Since commit c93c92f30 (http: update base URLs when we see
redirects, 2013-09-28), the client usually rewrites the base
URL such that all further requests will go to Bob's server.
But this is done by textually matching the URL. If we were
originally looking for "http://mallory/repo.git/info/refs",
and we got pointed at "http://bob/other.git/info/refs", then
we know that the right root is "http://bob/other.git".
If the redirect appears to change more than just the root,
we punt and continue to use the original server. E.g.,
imagine the redirect adds a URL component that Bob's server
will ignore, like "http://bob/other.git/info/refs?dummy=1".
We can solve this by aborting in this case rather than
silently continuing to use Mallory's server. In addition to
protecting from sha1 leakage, it's arguably safer and more
sane to refuse a confusing redirect like that in general.
For example, part of the motivation in c93c92f30 is
avoiding accidentally sending credentials over clear http,
just to get a response that says "try again over https". So
even in a non-malicious case, we'd prefer to err on the side
of caution.
The downside is that it's possible this will break a
legitimate but complicated server-side redirection scheme.
The setup given in the newly added test does work, but it's
convoluted enough that we don't need to care about it. A
more plausible case would be a server which redirects a
request for "info/refs?service=git-upload-pack" to just
"info/refs" (because it does not do smart HTTP, and for some
reason really dislikes query parameters). Right now we
would transparently downgrade to dumb-http, but with this
patch, we'd complain (and the user would have to set
GIT_SMART_HTTP=0 to fetch).

The default version name for a Git binary is computed by running
"git describe" on the commit the binary is made out of, basing on a
tag whose name matches "v[0-9]*", e.g. v2.11.0-rc2-2-g7f1dc9.
In the very early days, with 9b88fcef7d ("Makefile: use git-describe
to mark the git version.", 2005-12-27), we used "--abbrev=4" to get
absolute minimum number of abbreviated commit object name. This was
later changed to match the default minimum of 7 with bf505158d0
("Git 1.7.10.1", 2012-05-01).
These days, the "default minimum" scales automatically depending on
the size of the repository, and there is no point in specifying a
particular abbreviation length; all we wanted since Git 1.7.10.1
days was to get "something reasonable we would use by default".
Just drop "--abbrev=<number>" from the invocation of "git describe"
and let the command pick what it thinks is appropriate, taking the
end user's configuration and the repository contents into account.

This options makes sorting ignore case, which is great when you have
branches named bug-12-do-something, Bug-12-do-some-more and
BUG-12-do-what and want to group them together. Sorting externally may
not be an option because we lose coloring and column layout from
git-branch and git-tag.
The same could be said for filtering, but it's probably less important
because you can always go with the ugly pattern [bB][uU][gG]-* if you're
desperate.
You can't have case-sensitive filtering and case-insensitive sorting (or
the other way around) with this though. For branch and tag, that should

Since 650c44925 (common-main: call git_extract_argv0_path(),
2016-07-01), the argv[0] that is seen in cmd_main() of
individual programs is always the basename of the
executable, as common-main strips off the full path. This
can produce confusing results for git-daemon, which wants to
re-exec itself.
For instance, if the program was originally run as
"/usr/lib/git/git-daemon", it will try just re-execing
"git-daemon", which will find the first instance in $PATH.
If git's exec-path has not been prepended to $PATH, we may
find the git-daemon from a different version (or no
git-daemon at all).
Normally this isn't a problem. Git commands are run as "git
daemon", the git wrapper puts the exec-path at the front of
$PATH, and argv[0] is already "daemon" anyway. But running
git-daemon via its full exec-path, while not really a
recommended method, did work prior to 650c44925. Let's make
it work again.
The real goal of 650c44925 was not to munge argv[0], but to
reliably set the argv0_path global. The only reason it
munges at all is that one caller, the git.c wrapper,
piggy-backed on that computation to find the command
basename. Instead, let's leave argv[0] untouched in
common-main, and have git.c do its own basename computation.
While we're at it, let's drop the return value from
git_extract_argv0_path(). It was only ever used in this one
callsite, and its dual purposes is what led to this
confusion in the first place.
Note that by changing the interface, the compiler can
confirm for us that there are no other callers storing the
return value. But the compiler can't tell us whether any of
the cmd_main() functions (besides git.c) were relying on the
basename munging. However, we can observe that prior to
650c44925, no other cmd_main() functions did that munging,
and no new cmd_main() functions have been introduced since
then. So we can't be regressing any of those cases.

There's only one case when get_worktrees() may skip main worktree, when

worktree and return something sensible in this case:
- In user-friendly mode, since we're not constraint by anything,
returning "(error)" should do the job (we already show "(detached
HEAD)" which is not machine-friendly). Actually errors should be
printed on stderr by parse_ref() (*)
- In plumbing mode, we do not show neither 'bare', 'detached' or
'branch ...', which is possible by the format description if I read
it right.
Careful readers may realize that when the local variable "head_ref" in
get_main_worktree() is emptied, add_head_info() will do nothing to
wt->head_sha1. But that's ok because head_sha1 is zero-ized in the

1335d76e45 ("merge: avoid "safer crlf" during recording of merge
results", 2016-07-08) tried to split make_cache_entry() call made
with CE_MATCH_REFRESH into a call to make_cache_entry() without one,
followed by a call to add_cache_entry(), refresh_cache() and another
add_cache_entry() as needed. However the conversion was botched in
that it forgot that refresh_cache() can return NULL, which was
handled correctly in make_cache_entry() but in the updated code.
This fixes https://github.com/git-for-windows/git/issues/952

In https://github.com/git-for-windows/git/issues/952, a complicated
scenario was described that leads to a segmentation fault in
cherry-pick.
It boils down to a certain code path involving a renamed file that is
dirty, for which `refresh_cache_entry()` returns `NULL`, and that
`NULL` not being handled properly.

Teach push to respect the --dry-run option when configured to
recursively push submodules 'on-demand'. This is done by passing the
--dry-run flag to the child process which performs a push for a
submodules when performing a dry-run.
In order to preserve good user experience, the additional check for
unpushed submodules is skipped during a dry-run when
--recurse-submodules=on-demand. The check is skipped because the submodule
pushes were performed as dry-runs and this check would always fail as the
submodules would still need to be pushed.

This patch adds a test to illustrate how push run with --dry-run doesn't
actually perform a dry-run when push is configured to push submodules
on-demand. Instead all submodules which need to be pushed are actually
pushed to their remotes while any updates for the superproject are
performed as a dry-run. This is a bug and not the intended behaviour of
a dry-run.

It seems a little silly to do a reachabilty check in the case where we
trust the user to access absolutely everything in the repository.
Also, it's racy in a distributed system -- perhaps one server
advertises a ref, but another has since had a force-push to that ref,
and perhaps the two HTTP requests end up directed to these different
servers.

In the event that a HTTP server closes the connection after giving a
200 but before giving any packets, we don't want to hang forever
waiting for a response that will never come. Instead, we should die
immediately.
One case where this happens is when attempting to fetch a dangling
object by its object name. In this case, the server dies before
sending any data. Prior to this patch, fetch-pack would wait for
data from the server, and remote-curl would wait for fetch-pack,
causing a deadlock.
Despite this patch, there is other possible malformed input that could
cause the same deadlock (e.g. a half-finished pktline, or a pktline but
no trailing flush). There are a few possible solutions to this:
1. Allowing remote-curl to tell fetch-pack about the EOF (so that
fetch-pack could know that no more data is coming until it says
something else). This is tricky because an out-of-band signal would
be required, or the http response would have to be re-framed inside
another layer of pkt-line or something.
2. Make remote-curl understand some of the protocol. It turns out
that in addition to understanding pkt-line, it would need to watch for
ack/nak. This is somewhat fragile, as information about the protocol
would end up in two places. Also, pkt-lines which are already at the
length limit would need special handling.
Both of these solutions would require a fair amount of work, whereas
this hack is easy and solves at least some of the problem.
Still to do: it would be good to give a better error message
than "fatal: The remote end hung up unexpectedly".

When a submodule is being merged or cherry-picked into a working
tree that already contains a corresponding empty directory, do not
record a conflict.
One situation where this bug appears is:
- Commit 1 adds a submodule
- Commit 2 removes that submodule and re-adds it into a subdirectory
(sub1 to sub1/sub1).
- Commit 3 adds an unrelated file.
Now the user checks out commit 1 (first deinitializing the submodule),
and attempts to cherry-pick commit 3. Previously, this would fail,
because the incoming submodule sub1/sub1 would falsely conflict with
the empty sub1 directory.
This patch ignores the empty sub1 directory, fixing the bug. We only
ignore the empty directory if the object being emplaced is a
submodule, which expects an empty directory.

In general, "git gc" may delete objects that another concurrent process
is using but hasn't created a reference to. Git has some mitigations,
but they fall short of a complete solution. Document this in the
git-gc(1) man page and add a reference from the documentation of the
gc.pruneExpire config variable.

To check whether a submodule needs to be pushed we need to collect all
changed submodules. Lets collect them first and then execute the
possibly expensive test whether certain revisions are already pushed
only once per submodule.
There is further potential for optimization since we can assemble one
command and only issued that instead of one call for each remote ref in
the submodule.

The try_parent_shorthands() function shows each parent via
show_rev(). We pass the correct parent sha1, but our "name"
parameter still points at the original refname. So asking
for a regular rev-parse works fine (it prints the sha1s),
but asking for the symbolic name gives nonsense like:
$ git rev-parse --symbolic HEAD^-1
HEAD
^HEAD
which is always an empty set of commits. Asking for "^!" is
likewise broken, with the added bonus that its prints ^HEAD
for _each_ parent. And "^@" just prints HEAD repeatedly.
Arguably it would be correct to just pass NULL as the name
here, and always get the parent expressed as a sha1. The
"--symbolic" documentaton claims only "as close to the
original input as possible", and we certainly fallback to
sha1s where necessary. But it's pretty easy to generate a
symbolic name on the fly from the original.

There are three codepaths that use a variable whose name is
pack_compression_level to affect how objects and deltas sent to a
packfile is compressed. Unlike zlib_compression_level that controls
the loose object compression, however, this variable was static to
each of these codepaths. Two of them read the pack.compression
configuration variable, using core.compression as the default, and
one of them also allowed overriding it from the command line.
The other codepath in bulk-checkin did not pay any attention to the
configuration.
Unify the configuration parsing to git_default_config(), where we
implement the parsing of core.loosecompression and core.compression
and make the former override the latter, by moving code to parse
pack.compression and also allow core.compression to give default to
this variable.

The "SECURITY" section of the gitnamespaces(7) man page described two
ways for a client to steal data from a server that wasn't intended to be
shared. Similar attacks can be performed by a server on a client, so
adapt the section to cover both directions and add it to the
git-fetch(1), git-pull(1), and git-push(1) man pages. Also add
references to this section from the documentation of server
configuration options that attempt to control data leakage but may not

builtin/fetch.c redundantly calculates refmaps for tags twice. Remove
the first calculation.
This is only a code simplification and slight performance improvement -
the result is unchanged, as the redundant refmaps are subsequently
removed by the invocation to "ref_remove_duplicates" anyway.
This was introduced in commit c5a84e9 ("fetch --tags: fetch tags *in
addition to* other stuff", 2013-10-29) when modifying the effect of the
--tags parameter to "git fetch". The refmap-for-tag calculation was

When we open object files, we try to do so with O_NOATIME.
This dates back to 144bde78e9 (Use O_NOATIME when opening
the sha1 files., 2005-04-23), which is an optimization to
avoid creating a bunch of dirty inodes when we're accessing
many objects. But a few things have changed since then:
1. In June 2005, git learned about packfiles, which means
we would do a lot fewer atime updates (rather than one
per object access, we'd generally get one per packfile).
2. In late 2006, Linux learned about "relatime", which is
generally the default on modern installs. So
performance around atimes updates is a non-issue there
these days.
All the world isn't Linux, but as it turns out, Linux
is the only platform to implement O_NOATIME in the
first place.
So it's very unlikely that this code is helping anybody
these days.

A platform might not support open(2) with O_CLOEXEC but may support
telling the same with fcntl(2) to flip FD_CLOEXEC bit on on an open

When the user does the lazy "git push" with no parameters with
push.default set to either "upstream", "simple" or "current",
we internally generated a refspec that has the current branch name
on the source side and used it to push.
However, the branch name (say "test") may be an ambiguous refname in
the context of the source repository---there may be a tag with the
same name, for example. This would trigger an unnecessary error
without any fault on the end-user's side.
Be explicit and give a full refname as the source side to avoid the
ambiguity. The destination side when pushing with the "current"
sent only the name of the branch and forcing the receiving end to
guess, which is the same issue. Be explicit there as well.

The way we structured the fallback/retry mechanism for opening with
O_NOATIME and O_CLOEXEC meant that if we failed due to lack of
support to open the file with O_NOATIME option (i.e. EINVAL), we
would still try to drop O_CLOEXEC first and retry, and then drop
O_NOATIME. A platform on which O_NOATIME is defined in the header
without support from the kernel wouldn't have a chance to open with
O_CLOEXEC option due to this code structure.
Arguably, O_CLOEXEC is more important than O_NOATIME, as the latter
is mostly about performance, while the former can affect correctness.
Instead use O_CLOEXEC to open the file, and then use fcntl(2) to set
O_NOATIME on the resulting file descriptor. open(2) itself does not
cause atime to be updated according to Linus [*1*].
The helper to do the former can be usable in the codepath in
ce_compare_data() that was recently added to open a file descriptor
with O_CLOEXEC; use it while we are at it.

The codepath we use to call iconv_open() has a provision to use a
fallback encoding when it fails, hoping that "UTF-8" being spelled
differently could be the reason why the library function did not
like the encoding names we gave it. Essentially, we turn what we
have observed to be used as variants of "UTF-8" (e.g. "utf8") into
the most official spelling and use that as a fallback.
We do the same thing for input and output encoding. Introduce a
helper function to do just one side and call that twice.
