55dfc8de18 expire_reflog(): it's not an each_ref_fn anymore
Prior to v1.5.4~14, expire_reflog() had to be an each_ref_fn because
it was passed to for_each_reflog(). Since then, there has been no
reason for it to implement the each_ref_fn interface. So...

* Remove the "unused" parameter (which took the place of "flags", but
  was really unused).

* Declare the last parameter to be (struct cmd_reflog_expire_cb *)
  rather than (void *).

c83a5099c8 commit: always populate GIT_AUTHOR_* variables
To figure out the author ident for a commit, we call
determine_author_info(). This function collects information
from the environment, other commits (in the case of
"--amend" or "-c/-C"), and the "--author" option. It then
uses fmt_ident to generate the final ident string that goes
into the commit object. fmt_ident is therefore responsible
for any quality or validation checks on what is allowed to
go into a commit.

Before returning, though, we call split_ident_line on the
result, and feed the individual components to hooks via the
GIT_AUTHOR_* variables. Furthermore, we do extra validation
by feeding the split to sane_ident_split(), which is pickier
than fmt_ident (in particular, it will complain about an empty
email field).  If this parsing or validation fails, we skip
updating the environment variables.

This is bad, because it means that hooks may silently see a
different ident than what we are putting into the commit. We
should drop the extra sane_ident_split checks entirely, and
take whatever fmt_ident has fed us (and what will go into
the commit object).

If parsing fails, we should actually abort here rather than
continuing (and feeding the hooks bogus data). However,
split_ident_line should never fail here. The ident was just
generated by fmt_ident, so we know that it's sane. We can
use assert_split_ident to double-check this.

Note that we also teach that assertion to check that we
found a date (it always should, but until now, no caller
cared whether we found a date or not). Checking the return
value of sane_ident_split is enough to ensure we have the
name/email pointers set, and checking date_begin is enough
to know that all of the date/tz variables are set.

fac908389d commit: loosen ident checks when generating template
When we generate the commit-message template, we try to
report an author or committer ident that will be of interest
to the user: an author that does not match the committer, or
a committer that was auto-configured.

When doing so, if we encounter what we consider to be a
bogus ident, we immediately die. This is a bad idea, because
our use of the idents here is purely informational.  Any
ident rules should be enforced elsewhere, because commits
that do not invoke the editor will not even hit this code
path (e.g., "git commit -mfoo" would work, but "git commit"
would not). So at best, we are redundant with other checks,
and at worse, we actively prevent commits that should
otherwise be allowed.

We should therefore do the minimal parsing we can to get a
value and not do any validation (i.e., drop the call to
sane_ident_split()).

In theory we could notice when even our minimal parsing
fails to work, and do the sane thing for each check (e.g.,
if we have an author but can't parse the committer, assume
they are different and print the author). But we can
actually simplify this even further.

We know that the author and committer strings we are parsing
have been generated by us earlier in the program, and
therefore they must be parseable. We could just call
split_ident_line without even checking its return value,
knowing that it will put _something_ in the name/mail
fields. Of course, to protect ourselves against future
changes to the code, it makes sense to turn this into an
assert, so we are not surprised if our assumption fails.

0e729c7ed5 update-ref: fix "verify" command with missing <oldvalue>
If "git update-ref --stdin" was given a "verify" command with no
"<newvalue>" at all (not even zeros), the code was mistakenly setting
have_old=0 (and leaving old_sha1 uninitialized). But this is
incorrect: this command is supposed to verify that the reference
doesn't exist. So in this case we really need old_sha1 to be set to
null_sha1 and have_old to be set to 1.

Moreover, since have_old was being set to zero, *no* check of the old
value was being done, so the new value of the reference was being set
unconditionally to the value in new_sha1. new_sha1, in turn, was set
to null_sha1 in the expectation that that was the old value and it
shouldn't be changed. But because the precondition was not being
checked, the result was that the reference was being deleted
unconditionally.

So, if <oldvalue> is missing, set have_old unconditionally and set
old_sha1 to null_sha1.

require_end_of_header(), and would otherwise easily run outside

3473ad0cf6 checkout: don't require a work tree when checking out into a new one
For normal use cases, it does not make sense for 'checkout' to work on
a bare repository, without a worktree. But "checkout --to" is an
exception because it _creates_ a new worktree. Allow this option to
run on bare repositories.

People who check out from a bare repository should remember that
core.logallrefupdates is off by default and it should be turned back
on. `--to` cannot do this automatically behind the user's back because
some user may deliberately want no reflog.

For people interested in repository setup/discovery code,
is_bare_repository_cfg (aka "core.bare") is unchanged by this patch,
which means 'true' by default for bare repos. Fortunately when we get
the repo through a linked checkout, is_bare_repository_cfg is never
used. So all is still good.

23af91d102 prune: strategies for linked checkouts
(alias R=$GIT_COMMON_DIR/worktrees/<id>)

 - linked checkouts are supposed to keep its location in $R/gitdir up
   to date. The use case is auto fixup after a manual checkout move.

 - linked checkouts are supposed to update mtime of $R/gitdir. If
   $R/gitdir's mtime is older than a limit, and it points to nowhere,
   worktrees/<id> is to be pruned.

 - If $R/locked exists, worktrees/<id> is not supposed to be pruned. If
   $R/locked exists and $R/gitdir's mtime is older than a really long
   limit, warn about old unused repo.

 - "git checkout --to" is supposed to make a hard link named $R/link
   pointing to the .git file on supported file systems to help detect
   the user manually deleting the checkout. If $R/link exists and its
   link count is greated than 1, the repo is kept.

1fdc2abf1b reflog: avoid constructing .lock path with git_path
Among pathnames in $GIT_DIR, e.g. "index" or "packed-refs", we want to
automatically and silently map some of them to the $GIT_DIR of the
repository we are borrowing from via $GIT_COMMON_DIR mechanism.  When
we formulate the pathname for its lockfile, we want it to be in the
same location as its final destination.  "index" is not shared and
needs to remain in the borrowing repository, while "packed-refs" is
shared and needs to go to the borrowed repository.

git_path() could be taught about the ".lock" suffix and map
"index.lock" and "packed-refs.lock" the same way their basenames are
mapped, but instead the caller can help by asking where the basename
(e.g. "index") is mapped to git_path() and then appending ".lock"
after the mapping is done.

557bd833bb git_path(): be aware of file relocation in $GIT_DIR
We allow the user to relocate certain paths out of $GIT_DIR via
environment variables, e.g. GIT_OBJECT_DIRECTORY, GIT_INDEX_FILE and
GIT_GRAFT_FILE. Callers are not supposed to use git_path() or
git_pathdup() to get those paths. Instead they must use
get_object_directory(), get_index_file() and get_graft_file()
respectively. This is inconvenient and could be missed in review (for
example, there's git_path("objects/info/alternates") somewhere in
sha1_file.c).

This patch makes git_path() and git_pathdup() understand those
environment variables. So if you set GIT_OBJECT_DIRECTORY to /foo/bar,
git_path("objects/abc") should return /foo/bar/abc. The same is done
for the two remaining env variables.

"git rev-parse --git-path" is the wrapper for script use.

This patch kinda reverts a0279e1 (setup_git_env: use git_pathdup
instead of xmalloc + sprintf - 2014-06-19) because using git_pathdup
here would result in infinite recursion:

  setup_git_env() -> git_pathdup("objects") -> .. -> adjust_git_path()
  -> get_object_directory() -> oops, git_object_directory is NOT set
  yet -> setup_git_env()

I wanted to make git_pathdup_literal() that skips adjust_git_path().
But that won't work because later on when $GIT_COMMON_DIR is
introduced, git_pathdup_literal("objects") needs adjust_git_path() to
replace $GIT_DIR with $GIT_COMMON_DIR.

1a83c240f2 git_snpath(): retire and replace with strbuf_git_path()
In the previous patch, git_snpath() is modified to allocate a new
strbuf buffer because vsnpath() needs that. But that makes it
awkward because git_snpath() receives a pre-allocated buffer from

and make it receive strbuf directly.

Using git_path() in update_refs_for_switch() which used to call
git_snpath() is safe because that function and all of its callers do
not keep any pointer to the round-robin buffer pool allocated by
get_pathname().

Before the previous commit, get_pathname returns an array of PATH_MAX
length. Even if git_path() and similar functions does not use the
whole array, git_path() caller can, in theory.

After the commit, get_pathname() may return a buffer that has just
enough room for the returned string and git_path() caller should never
write beyond that.

Make git_path(), mkpath() and git_path_submodule() return a const
buffer to make sure callers do not write in it at all.

This could have been part of the previous commit, but the "const"
conversion is too much distraction from the core changes in path.c.

00a6fa0720 push: truly use "simple" as default, not "upstream"
The plan for the push.default transition had all along been
to use the "simple" method rather than "upstream" as a
default if the user did not specify their own push.default
value. Commit 11037ee (push: switch default from "matching"
to "simple", 2013-01-04) tried to implement that by moving
PUSH_DEFAULT_UNSPECIFIED in our switch statement to
fall-through to the PUSH_DEFAULT_SIMPLE case.

When the commit that became 11037ee was originally written,
that would have been enough. We would fall through to
calling setup_push_upstream() with the "simple" parameter
set to 1. However, it was delayed for a while until we were
ready to make the transition in Git 2.0.

And in the meantime, commit ed2b182 (push: change `simple`
to accommodate triangular workflows, 2013-06-19) threw a
monkey wrench into the works. That commit drops the "simple"
parameter to setup_push_upstream, and instead checks whether
the global "push_default" is PUSH_DEFAULT_SIMPLE. This is
right when the user has explicitly configured push.default
to simple, but wrong when we are a fall-through for the
"unspecified" case.

We never noticed because our push.default tests do not cover
the case of the variable being totally unset; they only
check the "simple" behavior itself.

from inside a VM, or when pushing a fix made on a user's machine (where
the developer is not at liberty to install an ssh daemon let alone know

The common workaround – pushing into a temporary branch and then merging
on the other machine – is no longer necessary with this patch.

59362e560d system_path(): always return free'able memory to the caller
The function sometimes returns a newly allocated string and
sometimes returns a borrowed string, the latter of which the callers
must not free().  The existing callers all assume that the return
value belongs to the callee and most of them copy it with strdup()
when they want to keep it around.  They end up leaking the returned
copy when the callee returned a new string because they cannot tell
if they should free it.

Change the contract between the callers and system_path() to make
the returned string owned by the callers; they are responsible for
freeing it when done, but they do not have to make their own copy to
store it away.

Adjust the callers to make sure they do not leak the returned string
once they are done, but do not bother freeing it just before dying,
exiting or exec'ing other program to avoid unnecessary churn.

4a45b2f347 repack_without_refs(): make the refnames argument a string_list
Most of the callers have string_lists available already, whereas two
of them had to read data out of a string_list into an array of strings
just to call this function. So change repack_without_refs() to take
the list of refnames to omit as a string_list, and change the callers
accordingly.

6d6d06c901 prune_remote(): sort delete_refs_list references en masse
Inserting items into a list in sorted order is O(N^2) whereas
appending them unsorted and then sorting the list all at once is
O(N lg N).

string_list_insert() also removes duplicates, and this change loses
that functionality. But the strings in this list, which ultimately
come from a for_each_ref() iteration, cannot contain duplicates.

c7bf68d6b4 init-db: improve the filemode trustability check
Some file systems do not support the executable bit:

  a) The user executable bit is always 0, e.g. VFAT mounted with
     -onoexec

  b) The user executable bit is always 1, e.g. cifs mounted with
     -ofile_mode=0755

  c) There are system where user executable bit is 1 even if it
     should be 0 like b), but the file mode can be maintained
     locally. chmod -x changes the file mode from 0766 to 0666,
     until the file system is unmounted and remounted and the file
     mode is 0766 again.

     This been observed when a Windows machine with NTFS exports a share to
     Mac OS X via smb or afp.

Case a) and b) are handled by the current code.  Case c) qualifies
as "non trustable executable bit" and core.filemode should be false,
but this is currently not done.

Detect when ".git/config" has the user executable bit set after
creat(".git/config", 0666) and set core.filemode to false.  Because
the permission bits on the file is whatever the end user already had
when we are asked to reinitialise an existing repository, and do not
give any information on the filesystem behaviour, do this only when
running "git init" to create a new repository.

1d31e5a2cd add: ignore only ignored files
"git add foo bar" adds neither foo nor bar when bar is ignored, but dies
to let the user recheck their command invocation. This becomes less
helpful when "git add foo.*" is subject to shell expansion and some of
the expanded files are ignored.

"git add --ignore-errors" is supposed to ignore errors when indexing
some files and adds the others. It does ignore errors from actual
indexing attempts, but does not ignore the error "file is ignored" as
outlined above. This is unexpected.

Change "git add foo bar" to add foo when bar is ignored, but issue
a warning and return a failure code as before the change.

That is, in the case of trying to add ignored files we now act the same
way (with or without "--ignore-errors") in which we act for more
severe indexing errors when "--ignore-errors" is specified.

d0e08d6233 config: fix parsing of "git config --get-color some.key -1"
Most of git-config's command line options use OPT_BIT to
choose an action, and then parse the non-option arguments
in a context-dependent way. However, --get-color and
--get-colorbool are unlike the rest of the options, in that
they are OPT_STRING, taking the option name as a parameter.

This generally works, because we then use the presence of
those strings to set an action bit anyway. But it does mean
that the option-parser will continue looking for options
even after the key (because it is not a non-option; it is an
argument to an option). And running:

  git config --get-color some.key -1

(to use "-1" as the default color spec) will barf, claiming
that "-1" is not an option. Instead, we should treat
--get-color and --get-colorbool as action bits, just like
--add, --get, and all the other actions, and then check that
the non-option arguments we got are sane. This fixes the
weirdness above, and makes those two options like all the
others.

This "fixes" a test in t4026, which checked that feeding
"-2" as a color should fail (it does fail, but prior to this
patch, because parseopt barfed, not because we actually ever
tried to parse the color).

This also catches other errors, like:

  git config --get-color some.key black blue

which previously silently ignored "blue" (and now will
complain that you gave too many arguments).

There are some possible regressions, though. We now disallow
these, which currently do what you would expect:

  # specifying other options after the action
  git config --get-color some.key --file whatever

  # using long-arg syntax
  git config --get-color=some.key

However, we have never advertised these in the
documentation, and in fact they did not work in some older
versions of git. The behavior was apparently switched as an
accidental side effect of d64ec16 (git config: reorganize to
use parseopt, 2009-02-21).

1f32ecffd8 create_default_files(): don't set u+x bit on $GIT_DIR/config
Since time immemorial, the test of whether to set "core.filemode"
has been done by trying to toggle the u+x bit on $GIT_DIR/config,
which we know always exists, and then testing whether the change
"took".  I find it somewhat odd to use the config file for this
test, but whatever.

The test code didn't set the u+x bit back to its original state
itself, instead relying on the subsequent call to git_config_set()
to re-write the config file with correct permissions.

But ever since

    daa22c6f8d config: preserve config file permissions on edits (2014-05-06)

git_config_set() copies the permissions from the old config file to
the new one.  This is a good change in and of itself, but it
invalidates the create_default_files()'s assumption, causing "git
init" to leave the executable bit set on $GIT_DIR/config.

Reset the permissions on $GIT_DIR/config when we are done with the
test in create_default_files().
