61b472ed8b git svn: reset invalidates the memoized mergeinfo caches
Since v1.7.0-rc2~11 (git-svn: persistent memoization, 2010-01-30),
git-svn has maintained some private per-repository caches in
.git/svn/.caches to avoid refetching and recalculating some
mergeinfo-related information with every 'git svn fetch'.

This memoization can cause problems, e.g consider the following case:

SVN repo:

  ... - a - b - c - m  <- trunk
          \        /
            d  -  e    <- branch1

The Git import of the above repo is at commit 'a' and doesn't know about
the branch1. In case of an 'git svn rebase', only the trunk of the
SVN repo is imported. During the creation of the git commit 'm', git svn
uses the svn:mergeinfo property and tries to find the corresponding git
commit 'e' to create 'm' with 'c' and 'e' as parents. But git svn rebase
only imports the current branch so commit 'e' is not imported.
Therefore git svn fails to create commit 'm' as a merge commit, because one
of its parents is not known to git. The imported history looks like this:

  ... - a - b - c - m  <- trunk

A later 'git svn fetch' to import all branches can't rewrite the commit 'm'
to add 'e' as a parent and to make it a real git merge commit, because it
was already imported.

That's why the imported history misses the merge and looks like this:

  ... - a - b - c - m  <- trunk
          \
            d  -  e    <- branch1

Right now the only known workaround for importing 'm' as a merge is to
force reimporting 'm' again from SVN, e.g. via

  $ git svn reset --revision $(git find-rev $c)
  $ git svn fetch

Sadly, this is where the behavior has regressed: git svn reset doesn't
invalidate the old mergeinfo cache, which is no longer valid for the
reimport, which leads to 'm' beeing imprted with only 'c' as parent.

As solution to this problem, this commit invalidates the mergeinfo cache
to force correct recalculation of the parents.

During development of this patch, several ways for invalidating the cache
where considered. One of them is to use Memoize::flush_cache, which will
call the CLEAR method on the underlying Memoize persistency implementation.
Sadly, neither Memoize::Storable nor the newer Memoize::YAML module
introduced in 68f532f4ba could optionally be used implement the
CLEAR method, so this is not an option.

Reseting the internal hash used to store the memoized values has the same
problem, because it calls the non-existing CLEAR method of the
underlying persistency layer, too.

Considering this and taking into account the different implementations
of the memoization modules, where Memoize::Storable is not in our control,
implementing the missing CLEAR method is not an option, at least not if
Memoize::Storable is still used.

Therefore the easiest solution to clear the cache is to delete the files
on disk in 'git svn reset'. Normally, deleting the files behind the back
of the memoization module would be problematic, because the in-memory
representation would still exist and contain wrong data. Fortunately, the
memoization is active in memory only for a small portion of the code.
Invalidating the cache by deleting the files on disk if it isn't active
should be safe.

e48fb750f5 git svn: handle errors and concurrent commits in dcommit
dcommit didn't handle errors returned by SVN and coped very
poorly with concurrent commits that appear in SVN repository
while dcommit was running. In both cases it left git repository
in inconsistent state: index (which was reset with `git reset
--mixed' after a successful commit to SVN) no longer matched the
checkouted tree, when the following commit failed or needed to be
rebased. See http://bugs.debian.org/676904 for examples.

This patch fixes the issues by:
- introducing error handler for dcommit. The handler will try
  to rebase or reset working tree before returning error to the
  end user. dcommit_rebase function was extracted out of cmd_dcommit
  to ensure consistency between cmd_dcommit and the error handler.
- calling `git reset --mixed' only once after all patches are
  successfully committed to SVN. This ensures index is not touched
  for most of the time of dcommit run.

2c3fd4bbb4 t/t5400: demonstrate breakage caused by informational message from prune
When receive-pack triggers 'git gc --auto' and 'git prune' is called to
remove a stale temporary object, 'git prune' prints an informational
message to stdout about the file that it will remove.  Since this message
is written to stdout, it is sent back over the transport channel to the git
client which tries to interpret it as part of the pack protocol and then
promptly terminates with a complaint about a protocol error.

Introduce a test which exercises the auto-gc functionality of receive-pack
and demonstrates this breakage.

35e2d03c2c Fix '\ No newline...' annotation in rewrite diffs
When a file that ends with an incomplete line is expressed as a
complete rewrite with the -B option, git diff incorrectly
appends the incomplete line indicator "\ No newline at end of
file" after such a line, rather than writing it on a line of its
own (the output codepath for normal output without -B does not
have this problem).  Add a LF after the incomplete line before
writing the "\ No newline ..." out to fix this.

d17cf5f3a3 tests: Introduce test_seq
Jeff King wrote:

	The seq command is GNU-ism, and is missing at least in older BSD
	releases and their derivatives, not to mention antique
	commercial Unixes.

	We already purged it in b3431bc (Don't use seq in tests, not
	everyone has it, 2007-05-02), but a few new instances have crept
	in. They went unnoticed because they are in scripts that are not

Replace them with test_seq that is implemented with a Perl snippet
(proposed by Jeff).  This is better than inlining this snippet
everywhere it's needed because it's easier to read and it's easier
to change the implementation (e.g. to C) if we ever decide to remove
Perl from the test suite.

Note that test_seq is not a complete replacement for seq(1).  It
just has what we need now, in addition that it makes it possible for
us to do something like "test_seq a m" if we wanted to in the
future.

There are also many places that do `for i in 1 2 3 ...` but I'm not sure
if it's worth converting them to test_seq.  That would introduce running
more processes of Perl.

84befcd0a4 grep: add a grep.patternType configuration setting
The grep.extendedRegexp configuration setting enables the -E flag on grep
by default but there are no equivalents for the -G, -F and -P flags.

Rather than adding an additional setting for grep.fooRegexp for current
and future pattern matching options, add a grep.patternType setting that
can accept appropriate values for modifying the default grep pattern
matching behavior. The current values are "basic", "extended", "fixed",
"perl" and "default" for setting -G, -E, -F, -P and the default behavior
respectively.

When grep.patternType is set to a value other than "default", the
grep.extendedRegexp setting is ignored. The value of "default" restores
the current default behavior, including the grep.extendedRegexp
behavior.

93c3fcbe4d git-svn: attempt to mimic SVN 1.7 URL canonicalization
Previously, our URL canonicalization didn't do much of anything.
Now it actually escapes and collapses slashes.  This is mostly a cut & paste
of escape_url from git-svn.

This is closer to how SVN 1.7's canonicalization behaves.  Doing it with
1.6 lets us chase down some problems caused by more effective canonicalization
without having to deal with all the other 1.7 issues on top of that.

* Remote URLs have to be canonicalized otherwise Git::SVN->find_existing_remote
  will think they're different.

* The SVN remote is now written to the git config canonicalized.  That
  should be ok.  Adjust a test to account for that.

b622d4d11d send-email: improve RFC2047 quote parsing
The RFC2047 unquoting, used to parse email addresses in From and Cc
headers, is broken in several ways:

* It erroneously substitutes ' ' for '_' in *the whole* header, even
  outside the quoted field. [Noticed by Christoph.]

* It is too liberal in its matching, and happily matches the start
  of one quoted chunk against the end of another, or even just
  something that looks like such an end. [Noticed by Junio.]

* It fundamentally cannot cope with encodings that are not a
  superset of ASCII, nor several (incompatible) encodings in the
  same header.

This patch fixes the first two by doing a more careful decoding of
the outer quoting (e.g. "=AB" to represent an octet whose value is
0xAB).  Fixing the fundamental issues is left for a future, more
intrusive, patch.

4337b5856f do not write null sha1s to on-disk index
We should never need to write the null sha1 into an index
entry (short of the 1 in 2^160 chance that somebody actually
has content that hashes to it). If we attempt to do so, it
is much more likely that it is a bug, since we use the null
sha1 as a sentinel value to mean "not valid".

The presence of null sha1s in the index (which can come
from, among other things, "update-index --cacheinfo", or by
reading a corrupted tree) can cause problems for later
readers, because they cannot distinguish the literal null
sha1 from its use a sentinel value.  For example, "git
diff-files" on such an entry would make it appear as if it
is stat-dirty, and until recently, the diff code assumed
such an entry meant that we should be diffing a working tree
file rather than a blob.

Ideally, we would stop such entries from entering even our
in-core index. However, we do sometimes legitimately add
entries with null sha1s in order to represent these sentinel
situations; simply forbidding them in add_index_entry breaks
a lot of the existing code. However, we can at least make
sure that our in-core sentinel representation never makes it
to disk.

To be thorough, we will test an attempt to add both a blob
and a submodule entry. In the former case, we might run into
problems anyway because we will be missing the blob object.
But in the latter case, we do not enforce connectivity
across gitlink entries, making this our only point of
enforcement. The current implementation does not care which
type of entry we are seeing, but testing both cases helps
future-proof the test suite in case that changes.

e54501004a diff: do not use null sha1 as a sentinel value
The diff code represents paths using the diff_filespec
struct. This struct has a sha1 to represent the sha1 of the
content at that path, as well as a sha1_valid member which
indicates whether its sha1 field is actually useful. If
sha1_valid is not true, then the filespec represents a
working tree file (e.g., for the no-index case, or for when
the index is not up-to-date).

The diff_filespec is only used internally, though. At the
interfaces to the diff subsystem, callers feed the sha1
directly, and we create a diff_filespec from it. It's at
that point that we look at the sha1 and decide whether it is
valid or not; callers may pass the null sha1 as a sentinel
value to indicate that it is not.

We should not typically see the null sha1 coming from any
other source (e.g., in the index itself, or from a tree).
However, a corrupt tree might have a null sha1, which would
cause "diff --patch" to accidentally diff the working tree
version of a file instead of treating it as a blob.

This patch extends the edges of the diff interface to accept
a "sha1_valid" flag whenever we accept a sha1, and to use
that flag when creating a filespec. In some cases, this
means passing the flag through several layers, making the
code change larger than would be desirable.

One alternative would be to simply die() upon seeing
corrupted trees with null sha1s. However, this fix more
directly addresses the problem (while bogus sha1s in a tree
are probably a bad thing, it is really the sentinel
confusion sending us down the wrong code path that is what
makes it devastating). And it means that git is more capable
of examining and debugging these corrupted trees. For
example, you can still "diff --raw" such a tree to find out
when the bogus entry was introduced; you just cannot do a
"--patch" diff (just as you could not with any other
corrupted tree, as we do not have any content to diff).

04083f278d test: allow prerequisite to be evaluated lazily
The test prerequisite mechanism is a useful way to allow some tests
in a test script to be skipped in environments that do not support
certain features (e.g. it is pointless to attempt checking how well
symbolic links are handled by Git on filesystems that do not support
them).  It is OK for commonly used prerequisites to be always tested
during start-up of a test script by having a codeblock that tests a
feature and calls test_set_prereq, but for an uncommon feature,
forcing 90% of scripts to pay the same probing overhead for
prerequisite they do not care about is wasteful.

Introduce a mechanism to probe the prerequiste lazily.  Changes are:

 - test_lazy_prereq () function, which takes the name of the
   prerequisite it probes and the script to probe for it, is
   added.  This only registers the name of the prerequiste that can
   be lazily probed and the script to eval (without running).

 - test_have_prereq() function (which is used by test_expect_success
   and also can be called directly by test scripts) learns to look
   at the list of prerequisites that can be lazily probed, and the
   prerequisites that have already been probed that way.  When asked
   for a prerequiste that can be but haven't been probed, the script
   registered with an earlier call to test_lazy_prereq is evaluated
   and the prerequisite is set.

 - test_run_lazy_prereq_() function is a helper to run the probe
   script with the same kind of sandbox as regular tests, helped by
   Jeff King.

Update the codeblock to probe and set SYMLINKS prerequisite using
the new mechanism as an example.

8c8b3bc3f4 t7502: test early quit from commit with bad ident
In commit f20f387, "git commit" notices and dies much
earlier when we have a bogus commit identity. That commit
did not add a test because we cannot do so reliably (namely,
we can only trigger the behavior on a system where the
automatically generated identity is bogus). However, now
that we have a prerequisite check for this feature, we can
add a test that will at least run on systems that produce
such a bogus identity.

1d7dc26498 t7502: handle systems where auto-identity is broken
Test t7502.21 checks whether we write the committer name
into COMMIT_EDITMSG when it has been automatically
determined. However, not all systems can produce valid
automatic identities.

Prior to f20f387 (commit: check committer identity more
strictly), this test worked even when we did not have a
valid automatic identity, since it did not run the strict
test until after we had generated the template. That commit
tightened the check to fail early (since we would fail
later, anyway), meaning that systems without a valid GECOS
name or hostname would fail the test.

We cannot just work around this, because it depends on
configuration outside the control of the test script.
Therefore we introduce a new test_prerequisite to run this
test only on systems where automatic ident works at all.

As a result, we can drop the confusing test_must_fail bit
from the test. The intent was that by giving "git commit"
invalid input (namely, nothing to commit), that it would
stop at a predictable point, whether we had a valid identity
or not, from which we could view the contents of
COMMIT_EDITMSG. Since that assumption no longer holds, and
we can only run the test when we have a valid identity,
there is no reason not to let commit run to completion. That
lets us be more robust to other unforeseen failures.

ceacd91a06 t7502: drop confusing test_might_fail call
In t7502.20, we run "git commit" and check that it warns us
that the author and committer identity are not the same
(this is always the case in the test environment, since we
set up the idents differently).

Instead of actually making a commit, we have a clean index,
so the "git commit" we run will fail. This is marked as
might_fail, which is not really correct; it will always fail
since there is nothing to commit.

However, the only reason not to do a complete commit would
be to see the intermediate state of the COMMIT_EDITMSG file
when the commit is not completed. We don't need to care
about this, though; even a complete commit will leave
COMMIT_EDITMSG for us to view.  By doing a real commit and
dropping the might_fail, we are more robust against other
unforeseen failures of "git commit" that might influence our
test result.

It might seem less robust to depend on the fact that "git
commit" leaves COMMIT_EDITMSG in place after a successful
commit. However, that brings this test in line with others
parts of the script, which make the same assumption.
Furthermore, if that ever does change, the right solution is
not to prevent commit from completing, but to set EDITOR to
a script that will record the contents we see. After all,
the point of these tests is to check what the user sees in
their EDITOR, so that would be the most direct test. For
now, though, we can continue to use the "shortcut" that
COMMIT_EDITMSG is left intact.

One of the tests tries to ensure that editor is not run due
to an early failure. However, it needs to quote the pathname
of the trash directory used in $GIT_EDITOR, since git will
pass it along to the shell. In other words, the test would
pass whether the code was correct or not, since the unquoted
editor specification would never run.

We never noticed the problem because the code is indeed
correct, so git-commit never even tried to run the editor.

We can also drop the setting of the $pwd variable from

(we can just use $(pwd) directly two lines later, since we
are interpolating the here-document). In the second
instance, it is totally pointless and probably just a
cut-and-paste from the first instance.

Finally, we can use a non-interpolating here document for

be8779f7ac git-submodule: work with GIT_DIR/GIT_WORK_TREE
The combination of GIT_DIR and GIT_WORK_TREE can be used to manage
files in one directory hierarchy while keeping the repository that
keeps track of them outside the directory hierarchy.  For example:

    git init --bare /path/to/there
    alias dotfiles="GIT_DIR=/path/to/there GIT_WORK_TREE=/path/to/here git"

    cd /path/to/here
    dotfiles add file
    dotfiles commit -a -m "add /path/to/here/file"
    ...

lets you manage files under /path/to/here/ in the repository located
at /path/to/there.

git-submodule however fails to add submodules, as it is confused by
GIT_DIR and GIT_WORK_TREE environment variables when it tries to
work in the submodule, like so:

    dotfiles submodule add http://path.to/submodule
    fatal: working tree '/path/to/here' already exists.

Simply unsetting the environment where the command works on the
submodule is sufficient to fix this, as it has set things up so
that GIT_DIR and GIT_WORK_TREE do not even have to point at the
repository and the working tree of the submodule.

f628825481 t/lib-httpd: handle running under --valgrind
Running the http tests with valgrind does not work for two
reasons:

  1. Apache complains about following the symbolic link from

  2. Apache does not pass through the GIT_VALGRIND variable
     to the backend CGI.

This patch fixes both problems. Unfortunately, there is a
slight hack we need to handle passing environment variables
through Apache. If we just tell it:

  PassEnv GIT_VALGRIND

then Apache will complain when GIT_VALGRIND is not set. If
we try:

  SetEnv GIT_VALGRIND ${GIT_VALGRIND}

then when GIT_VALGRIND is not set, it will pass through the
literal "${GIT_VALGRIND}". Instead, we now unconditionally
pass through GIT_VALGRIND from lib-httpd.sh into apache,
even if it is empty.

However, if $HOME is unset, then home_config_paths will return

c12f82ae63 diff: test precedence of external diff drivers
There are three ways to specify an external diff command:
GIT_EXTERNAL_DIFF in the environment, diff.external in the
config, or a "diff" gitattribute. The current order of
precedence is:

  1. gitattribute

  2. GIT_EXTERNAL_DIFF

  3. diff.external

Usually our rule is that environment variables should take
precedence over on-disk config (i.e., option 2 should come
before option 1). However, this situation is trickier than
some, because option 1 is more specific to the individual
file than option 2 (which affects all files), so it might be
preferable. So the current behavior can be seen as
implementing "do the specific thing if we can, but fall back
to this general thing".

This is probably not what we would do if we were writing git
from scratch, but it has been this way for several years,
and is not worth changing. So let's at least document that
this is the way it's supposed to work with a test.

While we're there, let's also make sure that diff.external
(which was not previously tested at all) works by running it
through the same tests as GIT_EXTERNAL_DIFF.

bd8c1a9b49 diff: correctly disable external_diff with --no-ext-diff
Upon seeing a type-change filepair, "diff --no-ext-diff" does not
show the usual "deletion followed by addition" split patch and does
not run the external diff driver either.

This is because the logic to disable external diff was placed at a
wrong level in the callchain.  run_diff_cmd() decides to show the
split patch only when external diff driver is not configured or
specified via GIT_EXTERNAL_DIFF environment, but this is done before
checking if --no-ext-diff was given.  To make things worse,
run_diff_cmd() checks --no-ext-diff and disables the output for such
a filepair completely, as the callchain below it (e.g. builtin_diff)
does not want to handle typechange filepairs.

6eafa6d096 submodules: don't stumble over symbolic links when cloning recursively
Since 69c3051 (submodules: refactor computation of relative gitdir path)
cloning a submodule recursively fails for nested submodules when a
symbolic link is part of the path to the work tree of the superproject.

This happens when module_clone() tries to find the relative paths between
the work tree and the git dir. When a symbolic link in current $PWD points
to a directory that is at a different level, then determining the number
of "../" needed to traverse to the superproject's work tree leads to a
wrong result.

As there is no portable way to say "pwd -P", use cd_to_toplevel to remove
the link from $PWD, which fixes this problem.

A test for this issue has been added to t7406.

ea2d4ed359 commit: fix "--amend --only" with no pathspec
When we do not have any pathspec, we typically disallow an
explicit "--only", because it makes no sense (your commit
would, by definition, be empty). But since 6a74642
(git-commit --amend: two fixes., 2006-04-20), we have
allowed "--amend --only" with the intent that it would amend
the commit, ignoring any contents staged in the index.

However, while that commit allowed the combination, we never
actually implemented the logic to make it work. The current
code notices that we have no pathspec and assumes we want to
do an as-is commit (i.e., the "--only" is ignored).

Instead, we must make sure to follow the partial-commit
code-path. We also need to tweak the list_paths function to
handle a NULL pathspec.

 - "git apply --build-fake-ancestor" reads the "index" lines from

 - "git commit-tree" reads a tree object name (not "tree-ish"), and

e2643617d7 sha1_name.c: many short names can only be committish
We know that the token "$name" that appear in "$name^{commit}",
"$name^4", "$name~4" etc. can only name a committish (either a
commit or a tag that peels to a commit).  Teach get_short_sha1() to
take advantage of that knowledge when disambiguating an abbreviated
SHA-1 given as an object name.

Now we have all the necessary logic to fall back on three-way merge when
the patch does not cleanly apply, insert the conflicted entries to the
index as appropriate.  This obviously triggers only when the "--index"
option is used.

When we fall back to three-way merge and some of the merges fail, just
like the case where the "--reject" option was specified and we had to
write some "*.rej" files out for unapplicable patches, exit the command
with non-zero status without showing the diffstat and summary.  Otherwise
they would make the list of problematic paths scroll off the display.

76759c7dff git on Mac OS and precomposed unicode
Mac OS X mangles file names containing unicode on file systems HFS+,
VFAT or SAMBA.  When a file using unicode code points outside ASCII
is created on a HFS+ drive, the file name is converted into
decomposed unicode and written to disk. No conversion is done if
the file name is already decomposed unicode.

Calling open("\xc3\x84", ...) with a precomposed "Ä" yields the same
result as open("\x41\xcc\x88",...) with a decomposed "Ä".

As a consequence, readdir() returns the file names in decomposed
unicode, even if the user expects precomposed unicode.  Unlike on
HFS+, Mac OS X stores files on a VFAT drive (e.g. an USB drive) in
precomposed unicode, but readdir() still returns file names in
decomposed unicode.  When a git repository is stored on a network
share using SAMBA, file names are send over the wire and written to
disk on the remote system in precomposed unicode, but Mac OS X
readdir() returns decomposed unicode to be compatible with its
behaviour on HFS+ and VFAT.

The unicode decomposition causes many problems:

- The names "git add" and other commands get from the end user may
  often be precomposed form (the decomposed form is not easily input
  from the keyboard), but when the commands read from the filesystem
  to see what it is going to update the index with already is on the
  filesystem, readdir() will give decomposed form, which is different.

- Similarly "git log", "git mv" and all other commands that need to
  compare pathnames found on the command line (often but not always
  precomposed form; a command line input resulting from globbing may
  be in decomposed) with pathnames found in the tree objects (should
  be precomposed form to be compatible with other systems and for
  consistency in general).

- The same for names stored in the index, which should be
  precomposed, that may need to be compared with the names read from
  readdir().

NFS mounted from Linux is fully transparent and does not suffer from
the above.

As Mac OS X treats precomposed and decomposed file names as equal,
we can

 - wrap readdir() on Mac OS X to return the precomposed form, and

 - normalize decomposed form given from the command line also to the
   precomposed form,

to ensure that all pathnames used in Git are always in the
precomposed form.  This behaviour can be requested by setting
"core.precomposedunicode" configuration variable to true.

The code in compat/precomposed_utf8.c implements basically 4 new
functions: precomposed_utf8_opendir(), precomposed_utf8_readdir(),
precomposed_utf8_closedir() and precompose_argv().  The first three
are to wrap opendir(3), readdir(3), and closedir(3) functions.

The argv[] conversion allows to use the TAB filename completion done
by the shell on command line.  It tolerates other tools which use
readdir() to feed decomposed file names into git.

When creating a new git repository with "git init" or "git clone",
"core.precomposedunicode" will be set "false".

The user needs to activate this feature manually.  She typically
sets core.precomposedunicode to "true" on HFS and VFAT, or file
systems mounted via SAMBA.

The original t9800 test code has a mix of assorted topics, some
of which are big enough to deserve their own homes.
Interdependencies between the topics make it confusing when

that debugging an individual test is difficult.

Split out three big chunks of tests into their own files:

    t9812-git-p4-wildcards.sh gets the 8 p4 wildcard tests

    t9813-git-p4-preserve-users.sh gets the 4 --preserve-user tests

    t9814-git-p4-rename.sh gets the 2 copy and rename tests

Test 9800 execution time drops from 29 sec to 9 sec.  The
sequential time to run all tests is a slower due to the three
extra p4d startup/shutdown sequences, but the overall parallel
execution time is about the same, at 52 sec.

ff59f6da84 fast-export: quote paths with spaces
A path containing a space must be quoted when used as an
argument to either the copy or rename commands (because
unlike other commands, the path is not the final thing on
the line for those commands).

Commit 6280dfdc3b (fast-export: quote paths in output,
2011-08-05) previously attempted to fix fast-export's
quoting by passing all paths through quote_c_style().
However, that function does not consider the space to be a
character which requires quoting, so let's special-case the
space inside print_path(). This will cause space-containing
paths to also be quoted in other commands where such quoting
is not strictly necessary, but it does not hurt to do so.

The test from 6280dfdc3b did not detect this because, while
it does introduce renames in the export stream, it does not
actually turn on rename detection, so they were presented as
pairs of deletions/adds. Using "-M" reveals the bug.

The reason is that 'git rebase' without -p/-i/-m internally calls 'git

no way of knowing what is a real patch and what is a commit message
that contains a patch.

Instead of outputing only the username and password, print all the

This is closer to what the C API does, and allows one to take the exact

0e8593dc5b config: write to $XDG_CONFIG_HOME/git/config file when appropriate
Teach git to write to $XDG_CONFIG_HOME/git/config if

 - it already exists,
 - $HOME/.gitconfig file doesn't, and
 - The --global option is used.

Otherwise, write to $HOME/.gitconfig when the --global option is
given, as before.

If the user doesn't create $XDG_CONFIG_HOME/git/config, there is
absolutely no change. Users can use this new file only if they want.

If $XDG_CONFIG_HOME is either not set or empty, $HOME/.config/git/config
will be used.

Advice for users who often come back to an old version of Git: you
shouldn't create this file.

dc79687e0b Let core.excludesfile default to $XDG_CONFIG_HOME/git/ignore
To use the feature of core.excludesfile, the user needs:

 1. to create such a file,

 2. and add configuration variable to point at it.

Instead, we can make this a one-step process by choosing a default value
which points to a filename in the user's $HOME, that is unlikely to
already exist on the system, and only use the presence of the file as a
cue that the user wants to use that feature.

And we use "${XDG_CONFIG_HOME:-$HOME/.config/git}/ignore" as such a
file, in the same directory as the newly added configuration file
("${XDG_CONFIG_HOME:-$HOME/.config/git}/config).  The use of this
directory is in line with XDG specification as a location to store
such application specific files.

Teach git to read the "gitconfig" information from a new location,

cluttering $HOME with many per-application configuration files.

In the order of reading, this file comes between the global
configuration file (typically $HOME/.gitconfig) and the system wide
configuration file (typically /etc/gitconfig).

We do not write to this new location (yet).

If $XDG_CONFIG_HOME is either not set or empty, $HOME/.config/git/config
will be used. This is in line with XDG specification.

When running 'git diff --quiet <file1> <file2>', if file1 or file2
is outside the repository, it will exit(0) even if the files differ.
It should exit(1) when they differ.

This happens because 'diff_no_index' looks at the 'found_changes'
member from 'diff_options' to determine if changes were made.  This
is the wrong thing to do, since it is only set if xdiff is actually
run and it finds a change (the diff machinery will optimize out the

flag needs to be taken into account.

b7be4366ea completion: respect $GIT_DIR
The __gitdir() helper function finds out the path of the git
repository by running 'git rev-parse --git-dir'.  However, it has a
shortcut first to avoid the overhead of running a git command in a
subshell when the current directory is at the top of the work tree,
i.e. when it contains a '.git' subdirectory.

If the 'GIT_DIR' environment variable is set then it specifies the
path to the git repository, and the autodetection of the '.git'
directory is not necessary.  However, $GIT_DIR is only taken into
acocunt by 'git rev-parse --git-dir', and the check for the '.git'
subdirectory is performed first, so it wins over the path given in
$GIT_DIR.

There are several completion (helper) functions that depend on
__gitdir(), and when the above case triggers the completion script
will do weird things, like offering refs, aliases, or stashes from a
different repository, or displaying wrong or broken prompt, etc.

So check first whether $GIT_DIR is set, and only proceed with checking
the '.git' directory in the current directory if it isn't.  'git
rev-parse' would also check whether the path in $GIT_DIR is a proper
'.git' directory, i.e. 'HEAD', 'refs/', and 'objects/' are present and
accessible, but we don't have to be that thorough for the bash prompt.
And we've lived with an equally permissive check for '.git' in the
current working directory for years anyway.

b0082b9d59 Demonstrate git-show is broken with ranges
The logic of git-show has remained largely unchanged since around
5d7eeee (git-show: grok blobs, trees and tags, too, 2006-12-14): start
a revision walker with no_walk=1, look at its pending objects and
handle them one-by-one.  For commits, this means stuffing them into a
new queue all alone, and running the walker.

Then Linus's f222abd (Make 'git show' more useful, 2009-07-13) came
along and set no_walk=0 whenever the user specifies a range.  Which
appears to work fine, until you actually prod it hard enough, as the
preceding commit shows: UNINTERESTING commits will be marked as such,
but not walked further to propagate the marks.

Demonstrate this with the main tests of this patch: 'showing a range
walks (Y shape)'.  The Y shape of history ensures that propagating the
UNINTERESTING marks is necessary to correctly exclude the main1
commit.  The only example I could find actually requires that the
negative revisions are listed later, and in this scenario a dotted
range actually works.  However, it is easy to find examples in git.git
where a dotted range is wrong, e.g.

  $ git show v1.7.0..v1.7.1 | grep ^commit | wc -l
  1297
  $ git rev-list v1.7.0..v1.7.1 | wc -l
  702

While there, also test a few other things that are not covered so far:
the -N way of triggering a range (added in 5853cae, DWIM 'git show -5'
to 'git show --do-walk -5', 2010-06-01), and the interactions of tags,
commits and ranges.

023e37c377 verify_filename(): ask the caller to chose the kind of diagnosis
verify_filename() can be called in two different contexts. Either we
just tried to interpret a string as an object name, and it fails, so
we try looking for a working tree file (i.e. we finished looking at
revs that come earlier on the command line, and the next argument
must be a pathname), or we _know_ that we are looking for a
pathname, and shouldn't even try interpreting the string as an
object name.

For example, with this change, we get:

  $ git log COPYING HEAD:inexistant
  fatal: HEAD:inexistant: no such path in the working tree.
  Use '-- <path>...' to specify paths that do not exist locally.
  $ git log HEAD:inexistant

d7236c4395 sha1_name: do not trigger detailed diagnosis for file arguments
diagnose_invalid_sha1_path() is meant to be called to diagnose a
misspelt <treeish>:<pathname> when <pathname> does not exist in
<treeish>.  However, the code may call it if <treeish>:<pathname> is
invalid (which triggers another call with only_to_die == 1), but for
another reason. This happens when calling e.g.

  git log existing-file HEAD:existing-file

because existing-file is a path and not a revision, the code
verifies that the arguments that follow to be paths.  This leads to
an incorrect message like "existing-file does not exist in HEAD",
even though the path exists in HEAD.

Check that the search for <pathname> in <treeish> fails before
triggering the diagnosis.

c517e73d0f t7400: avoid path mangling issues
A recently introduced test uses an absolute path. But when run on Windows
using the MSYS bash, such a path is mangled into a Windows style path when
it is passed to 'git config'. The subsequent 'test' then compares the
mangled path to the unmangled version and reports a failure.

A path beginning with two slashes denotes a network directory
(//server/share path) and is not mangled. Use that trick to side-step the
issue. Just in case that 'git submodule init' regresses in such a way that
it accesses the URL, use a path name that is unlikely to exist on POSIX
systems, and that cannot be a server name on Windows.

c214538416 rebase -i: teach "--exec <cmd>"
During an interactive rebase session, it is sometimes desirable to
run tests on each commit in the resulting history.  This can be done
by adding "exec <test command>" when editing the insn sheet, but the
command used for testing is often the same for all resulting commits.

By passing "--exec <cmd>" from the command line, automatically add
these "exec" lines after each commit in the final history.  To work
well with the --autosquash option, these are added at the end of
each run of "fixup" and "squash".

93b291e071 completion: put main git and gitk completion functions back into git namespace
Commit 7f02f3d7 (completion: rename internal helpers _git and _gitk,
2012-05-19) renamed said functions to _main_git() and _main_gitk(),
respectively.  By convention the name of our git-completion-specific
functions start with '_git' or '__git' prefix, so rename those
functions once again to put them back into our "namespace".  Use the
two underscore prefix, because _git_main() could be mistaken for the
completion function of the (not yet existing) 'git main' command.

2a8a4490c2 gitweb: Skip 'modification times' tests when no date parser available
The If-Modified-Since support in Gitweb is conditional on the
availability of a date parser from either the HTTP::Date or
Time::ParseDate modules. If a suitable parser is not available,
then the corresponding 'modification times' tests should be skipped.

Introduce the DATE_PARSER test prerequisite and use it to skip
all of the dependent tests.

a3428205e6 t: Replace 'perl' by $PERL_PATH
GIT-BUILD-OPTIONS defines PERL_PATH to be used in the test suite. Only a
few tests already actually use this variable when perl is needed. The
other test just call 'perl' and it might happen that the wrong perl
interpreter is used.

This becomes problematic on Windows, when the perl interpreter that is
compiled and installed on the Windows system is used, because this perl
interpreter might introduce some unexpected LF->CRLF conversions.

This patch makes sure that $PERL_PATH is used everywhere in the test suite
and that the correct perl interpreter is used.

a14ad10911 t1304: improve setfacl prerequisite setup
t1304 first runs setfacl as an experiment to see whether the
filesystem supports ACLs, and skips the remaining tests if
it does not. However, our setfacl run did not exercise the
ACLs very well, and some filesystems may support our initial
setfacl, but not the rest of the test.

In particular, some versions of ecryptfs will erroneously
apply the umask on top of an inherited directory ACL,
causing our tests to fail. Let's be more careful and make
sure both that we can read back the user ACL we set, and
that the inherited ACL is propagated correctly. The latter
catches the ecryptfs bug, but may also catch other bugs
(e.g., an implementation which does not handle inherited
ACLs at all).

Since we're making the setup more complex, let's move it
into its own test. This will hide the output for us unless
the user wants to run "-v" to see it (and we don't need to
bother printing anything about setfacl failing; the
remaining tests will properly print "skip" due to the
missing prerequisite).

758615e251 submodule: fix handling of superproject origin URLs like foo, ./foo and ./foo/bar
Currently git submodule init and git submodule sync fail with an error
if the superproject origin URL is of the form foo but succeed if the
superproject origin URL is of the form ./foo or ./foo/bar or foo/bar.

This change makes handling of the foo case behave like the handling
of the ./foo case and also ensures that superfluous leading and

967b2c6673 submodule: fix sync handling of some relative superproject origin URLs
When the origin URL of the superproject is itself relative, git submodule sync
configures the remote.origin.url configuration property of the submodule
with a path that is relative to the work tree of the superproject
rather than the work tree of the submodule.

To fix this an 'up_path' that navigates from the work tree of the submodule
to the work tree of the superproject needs to be prepended to the URL
otherwise calculated.

Correct handling of superproject origin URLs like foo, ./foo and ./foo/bar is
left to a subsequent patch since an additional change is required to handle
these cases.

The documentation of resolve_relative_url() is expanded to give a more thorough
description of the function's objective.

  2. It did not use test_must_fail.

  3. It did not use test_line_count.

  4. It checked for the non-existence of a ref by looking in the
     .git/refs directory (since we pack refs during clone
     these days, this will always be succeed, making the
     test useless).

     Note that one call to "-e .git/refs/..." remains,

cf2ba13ac6 pack-objects: use streaming interface for reading large loose blobs
git usually streams large blobs directly to packs. But there are cases
where git can create large loose blobs (unpack-objects or hash-object
over pipe). Or they can come from other git implementations.
core.bigfilethreshold can also be lowered down and introduce a new
wave of large loose blobs.

Use streaming interface to read/compress/write these blobs in one
go. Fall back to normal way if somehow streaming interface cannot be
used.

9ec2dde9f3 index-pack: use streaming interface on large blobs (most of the time)
unpack_raw_entry() will not allocate and return decompressed blobs if
they are larger than core.bigFileThreshold. sha1_object() may not be
called on those objects because there's no actual content.

sha1_object() is called later on those objects, where we can safely
use get_data_from_pack() to retrieve blob content for checking.
However we always do that when we definitely need the blob
content. And we often don't.

There are two cases when we may need object content. The first case is
when we find an in-repo blob with the same SHA-1. We need to do
collision test, byte-on-byte. If this test is on, the blob must be
loaded on memory (i.e. no streaming). Normally (e.g. in
fetch/pull/clone) this does not happen because git avoid to send
objects that client already has.

The other case is when --strict is specified and the object in
question is not a blob, which can't happen in reality becase we deal
with large _blobs_ here.

Note: --verify (or git-verify-pack) a pack from current repository
will trigger collision test on every object in the pack, which
effectively disables this patch. This could be easily worked around by
setting GIT_DIR to an imaginary place with no packs.

af31a456b4 completion: split __git_ps1 into a separate script
bash-completion 1.90 shipped with support to load completions
dynamically[1], which means the git completion script wouldn't be loaded
until the user types 'git <tab>'--this creates a problem to people using
__git_ps1(); that function won't be available when the shell is first
created.

For now distributions have workarounded this issue by moving the git
completion to the "compatdir"[2]; this of course is not ideal.

The solution, proposed by Kerrick Staley[3], is to split the git script
in two; the part that deals with __git_ps1() in one (i.e.
git-prompt.sh), and everything else in another (i.e.
git-completion.bash).

Another benefit of this is that zsh user that are not interested in the
bash completion can use it for their prompts, which has been tried
before[4].

The only slight issue is that __gitdir() would be duplicated, but this
is probably not a big deal.

So let's go ahead and move __git_ps1() to a new file.

While at this, I took the liberty to reformat the help text in the new
file.

Implement this functionality by creating and inserting extra grep_pat

The original pattern is truncated in place to make it contain only the

cb8ad289c6 Consistently use "superproject" instead of "supermodule"
We fairly consistently say "superproject" and never "supermodule" these
days. But there are seven occurrences of "supermodule" left in the current
work tree. Three appear in Release Notes for 1.5.3 and 1.7.7, three in
test names and one in a C-code comment.

Replace all occurrences of "supermodule" outside of the Release Notes
(which shouldn't be changed after the fact) with "superproject" for
consistency.

27ccd8d1a3 t3404: begin "exchange commits with -p" test with correct preconditions
The test case shows a bug in 'rebase -p', but even if the bug were fixed
the test would fail because it did not ensure that the preconditions match
the postconditions that were checked. Insert the suitable 'git checkout'.

7f02f3d7ec completion: rename internal helpers _git and _gitk
Would be useful to provide backwards compatibility for _git. Also, zsh
completion uses _git, and it cannot be changed.

60f26f6348 t/Makefile: retain cache t/.prove across prove runs
prove(1) can write a summary of its test results and timings into a
cache file, t/.prove, then use this information during later runs for
various purposes.  But deleting t/.prove after every test run defeats
this purpose.  So do not delete t/.prove as part of "make
DEFAILT_TEST_TARGET=prove test".  (Continue to delete the file on
"make clean".)

9ef5b2bd16 Fix t3411.3 to actually rebase something
The test intends to rebase a branchy history onto a later commit, but it
forgot to reset HEAD back to an earlier commit before it set up the side
branches. In the end, every "rebased" commit was only a fast-forward and
the 'rebase -p' did not change the commit graph at all. Insert the missing
checkout that moves to an earlier commit.
