dfa1725a3e fix http auth with multiple curl handles
HTTP authentication is currently handled by get_refs and fetch_ref, but
not by fetch_object, fetch_pack or fetch_alternates. In the
single-threaded case, this is not an issue, since get_refs is always
called first. It recognigzes the 401 and prompts the user for
credentials, which will then be used subsequently.

If the curl multi interface is used, however, only the multi handle used
by get_refs will have credentials configured. Requests made by other
handles fail with an authentication error.

Fix this by setting CURLOPT_USERPWD whenever a slot is requested.

a6754cda43 rebase -i continue: don't skip commits that only change submodules
When git-rebase--interactive stops due to a conflict and the only change
to be committed is in a submodule, the test for whether there is
anything to be committed ignores the staged submodule change.  This
leads rebase to skip creating the commit for the change.

While unstaged submodule changes should be ignored to avoid needing to
update submodules during a rebase, it is safe to remove the
--ignore-submodules option to diff-index because --cached ensures that
it is only checking the index.  This was discussed in [1] and a test is
included to ensure that unstaged changes are still ignored correctly.

38f865c27d run-command: treat inaccessible directories as ENOENT
When execvp reports EACCES, it can be one of two things:

  1. We found a file to execute, but did not have
     permissions to do so.

  2. We did not have permissions to look in some directory
     in the $PATH.

In the former case, we want to consider this a
permissions problem and report it to the user as such (since
getting this for something like "git foo" is likely a
configuration error).

In the latter case, there is a good chance that the
inaccessible directory does not contain anything of
interest. Reporting "permission denied" is confusing to the
user (and prevents our usual "did you mean...?" lookup). It
also prevents git from trying alias lookup, since we do so
only when an external command does not exist (not when it
exists but has an error).

This patch detects EACCES from execvp, checks whether we are
in case (2), and if so converts errno to ENOENT. This
behavior matches that of "bash" (but not of simpler shells
that use execvp more directly, like "dash").

Test stolen from Junio.

135dadef71 push: error out when the "upstream" semantics does not make sense
The user can say "git push" without specifying any refspec.  When using
the "upstream" semantics via the push.default configuration, the user
wants to update the "upstream" branch of the current branch, which is the
branch at a remote repository the current branch is set to integrate with,
with this command.

However, there are cases that such a "git push" that uses the "upstream"
semantics does not make sense:

 - The current branch does not have branch.$name.remote configured.  By
   definition, "git push" that does not name where to push to will not
   know where to push to.  The user may explicitly say "git push $there",
   but again, by definition, no branch at repository $there is set to
   integrate with the current branch in this case and we wouldn't know
   which remote branch to update.

 - The current branch does have branch.$name.remote configured, but it
   does not specify branch.$name.merge that names what branch at the
   remote this branch integrates with. "git push" knows where to push in
   this case (or the user may explicitly say "git push $remote" to tell us
   where to push), but we do not know which remote branch to update.

 - The current branch does have its remote and upstream branch configured,
   but the user said "git push $there", where $there is not the remote
   named by "branch.$name.remote".  By definition, no branch at repository
   $there is set to integrate with the current branch in this case, and
   this push is not meant to update any branch at the remote repository
   $there.

The first two cases were already checked correctly, but the third case was
not checked and we ended up updating the branch named branch.$name.merge
at repository $there, which was totally bogus.

4066bd6797 add--interactive: ignore unmerged entries in patch mode
When "add -p" sees an unmerged entry, it shows the combined
diff and then immediately skips the hunk. This can be
confusing in a variety of ways, depending on whether there
are other changes to stage (in which case you get the
superfluous combined diff output in between other hunks) or
not (in which case you get the combined diff and the program
exits immediately, rather than seeing "No changes").

The current behavior was not planned, and is just what the
implementation happens to do. Instead, let's explicitly
remove unmerged entries from our list of modified files, and
print a warning that we are ignoring them.

We can cheaply find which entries are unmerged by adding
"--raw" output to the "diff-files --numstat" we already run.
There is one non-obvious thing we must change when parsing
this combined output. Before this patch, when we saw a
numstat line for a file that did not have index changes, we
would create a new record with 'unchanged' in the 'INDEX'
field.  Because "--raw" comes before "--numstat", we must
move this special-case down to the raw-line case (and it is
sufficient to move it rather than handle it in both places,
since any file which has a --numstat will also have a --raw
entry).

e32a4581bc http-backend: respect existing GIT_COMMITTER_* variables
The http-backend program sets default GIT_COMMITTER_NAME and
GIT_COMMITTER_EMAIL variables based on the REMOTE_USER and
REMOTE_ADDR variables provided by the webserver. However, it
unconditionally overwrites any existing GIT_COMMITTER
variables, which may have been customized by site-specific
code in the webserver (or in a script wrapping http-backend).

Let's leave those variables intact if they already exist,
assuming that any such configuration was intentional. There
is a slight chance of a regression if somebody has set
GIT_COMMITTER_* for the entire webserver, not intending it
to leak through http-backend. We could protect against this
by passing the information in alternate variables.  However,
it seems unlikely that anyone will care about that
regression, and there is value in the simplicity of using
the common variable names that are used elsewhere in git.

While we're tweaking the environment-handling in
http-backend, let's switch it to use argv_array to handle
the list of variables. That makes the memory management much
simpler.

b7d565ea4c gitweb: refactor If-Modified-Since handling
The current gitweb only generates Last-Modified and handles
If-Modified-Since headers for the git_feed action.  This patch breaks
the Last-Modified and If-Modified-Since handling code out from

code easy to reuse for other actions.

Only gitweb actions which can easily calculate a modification time
should use exit_if_unmodified_since, as the goal is to balance local
processing time vs. upload bandwidth.

4f7cb99ada merge-recursive: don't detect renames of empty files
Merge-recursive detects renames so that if one side modifies
"foo" and the other side moves it to "bar", the modification
is applied to "bar". However, our rename detection is based
on content analysis, it can be wrong (i.e., two files were
not intended as a rename, but just happen to have the same
or similar content).

This is quite rare if the files actually contain content,
since two unrelated files are unlikely to have exactly the
same content.  However, empty files present a problem, in
that there is nothing to analyze. An uninteresting
placeholder file with zero bytes may or may not be related
to a placeholder file with another name.

The result is that adding content to an empty file may cause
confusion if the other side of a merge removed it; your
content may end up in another random placeholder file that
was added.

Let's err on the side of caution and not consider empty
files as renames. This will cause a modify/delete conflict
on the merge, which will let the user sort it out
themselves.

ae2f203ef7 clean: preserve nested git worktree in subdirectories
remove_dir_recursively() has a check to avoid removing the directory it
was asked to remove without recursing into it and report success when the
directory is the top level of a working tree of a nested git repository,
to protect such a repository from "clean -f" (without double -f). If a
working tree of a nested git repository is in a subdirectory of a toplevel
project, however, this protection did not apply by mistake; we forgot to
pass the REMOVE_DIR_KEEP_NESTED_GIT down to the recursive removal
codepath.

This requires us to also teach the higher level not to remove the
directory it is asked to remove, when the recursed invocation did not
remove the directory it was asked to remove due to a nested git
repository, as it is not an error to leave the parent directories of such
a nested repository.

dabba590aa notes-merge: Don't remove .git/NOTES_MERGE_WORKTREE; it may be the user's cwd
When a manual notes merge is committed or aborted, we need to remove the
temporary worktree at .git/NOTES_MERGE_WORKTREE. However, removing the
entire directory is not good if the user ran the 'git notes merge
--commit/--abort' from within that directory. On Windows, the directory
removal would simply fail, while on POSIX systems, users would suddenly
find themselves in an invalid current directory.

Therefore, instead of deleting the entire directory, we delete everything
_within_ the directory, and leave the (empty) directory in place.

This would cause a subsequent notes merge to abort, complaining about a
previous - unfinished - notes merge (due to the presence of
.git/NOTES_MERGE_WORKTREE), so we also need to adjust this check to only
trigger when .git/NOTES_MERGE_WORKTREE is non-empty.

Finally, adjust the t3310 manual notes merge testcases to correctly handle
the existence of an empty .git/NOTES_MERGE_WORKTREE directory.

a0be62c100 notes-merge: use opendir/readdir instead of using read_directory()
notes_merge_commit() only needs to list all entries (non-recursively)
under a directory, which can be easily accomplished with
opendir/readdir and would be more lightweight than read_directory().

read_directory() is designed to list paths inside a working
directory. Using it outside of its scope may lead to undesired effects.

Apparently, one of the undesired effects of read_directory() is that it
doesn't deal with being given absolute paths. This creates problems for
notes_merge_commit() when git_path() returns an absolute path, which
happens when the current working directory is in a subdirectory of the
.git directory.

01bfec8e52 t3310: illustrate failure to "notes merge --commit" inside $GIT_DIR/
The 'git notes merge' command expected to be run from the working
tree of the project being annotated, and did not anticipate getting
run inside $GIT_DIR/.

However, because we use $GIT_DIR/NOTES_MERGE_WORKTREE as a temporary
working space for the user to work on resolving conflicts, it is not
unreasonable for a user to run "git notes merge --commit" there. But
the command fails to do so.

The commit message which added those tests (861444f 't: add test
harness for external credential helpers' 2011-12-10) provided nice
documentation in the commit message. Let's make it more visible
by putting it in the test description.

The documentation is updated to reflect the fact that
GIT_TEST_CREDENTIAL_HELPER must be set for
GIT_TEST_CREDENTIAL_HELPER_TIMEOUT to be used
and GIT_TEST_CREDENTIAL_HELPER_SETUP can be used.

6440d3417c diff: tweak a _copy_ of diff_options with word-diff
When using word diff, the code sets the word_regex from various
defaults if it was not set already.  The problem is that it does this
on the original diff_options, which will also be used in subsequent
diffs.

This means that when the word_regex is not given on the command line,
only the first diff for which a setting for word_regex (either from
attributes or diff.wordRegex) ever takes effect.  This value then
propagates to the rest of the diff runs and in particular prevents
further attribute lookups.

Fix the problem of changing diff state once and for all, by working
with a _copy_ of the diff_options.

418a1435f1 fmt-merge-msg: show those involved in a merged series
As we already walk the history of the branch that gets merged to
come up with a short log, let's label it with names of the primary
authors, so that the user who summarizes the merge can easily give
credit to them in the log message.

Also infer the names of "lieutents" to help integrators at higher
level of the food-chain to give credit to them, by counting:

 * The committer of the 'tip' commit that is merged
 * The committer of merge commits that are merged

Often the first one gives the owner of the history being pulled, but
his last pull from his sublieutenants may have been a fast-forward,
in which case the first one would not be.  The latter rule will
count the integrator of the history, so together it might be a
reasonable heuristics.

There are two special cases:

 - The "author" credit is omitted when the series is written solely
   by the same author who is making the merge. The name can be seen
   on the "Author" line of the "git log" output to view the log
   message anyway.

 - The "lieutenant" credit is omitted when there is only one key
   committer in the merged branch and it is the committer who is
   making the merge. Typically this applies to the case where the
   developer merges his own branch.

2983c0e22a test: use numstat instead of diffstat in binary-diff test
git's --stat output is intended for humans and since v1.7.9.2~13
(2012-02-01) varies by locale.  The tests in this script using "apply
--stat" are meant to check two things:

 - how binary file changes are accounted for and printed in
   git's diffstat format

 - that "git apply" can parse the various forms of binary diff

Split these two kinds of check into separate tests, and use --numstat
instead of --stat in the latter.  This way, we lose less test coverage
when git is being run without writing its output in the C locale (for
example because GETTEXT_POISON is enabled) and there are fewer tests
to change if the --stat output needs to be tweaked again.

While at it, use commands separated by && that read and write to
temporary files in place of pipelines so segfaults and other failures
in the upstream of the processing pipeline don't get hidden.

git's diff --stat output is intended for human consumption and

that git stash show defaults to --stat and tweak the rest of the
"stash show" tests that showed a diffstat to use numstat.

This way, there are fewer tests to tweak if the diffstat format
changes again.  This also improves test coverage when running tests
with git configured not to write its output in the C locale (e.g.,
via GETTEXT_POISON=Yes).

2593633f5a test: test cherry-pick functionality and output separately
Since v1.7.3-rc0~26^2~9 (revert: report success when using option
--strategy, 2010-07-14), the cherry-pick-many-commits test checks the
format of output written to the terminal during a cherry-pick sequence
in addition to the functionality.  There is no reason those have to
be checked in the same test, though, and it has some downsides:

 - when progress output is broken, the test result does not convey
   whether the functionality was also broken or not

 - it is not immediately obvious when reading that these checks are
   meant to prevent regressions in details of the output format and
   are not just a roundabout way to check functional details like the
   number of commits produced

 - there is a temptation to include the same kind of output checking
   for every new cherry-pick test, which would make future changes
   to the output unnecessarily difficult

Put the tests from v1.7.3-rc0~26^2~9 in separate assertions, following
the principle "test one feature at a time".

ef7db1933b test: modernize funny-names test style
This is one of the early tests, so it uses a style that by modern
standards can be hard to read.  Tweak it to:

 - clearly declare what assertion each test is designed to check

 - mark tests that create state later tests will depend on with the
   word "setup" so people writing or running tests know the others
   can be skipped or reordered safely

 - put commands that populate a file with expected output inside
   the corresponding test stanza, so it is easier to see by eye
   where each test begins and ends

 - instead of pipelines, use commands that read and write a
   temporary file, so bugs causing commands to segfault or produce
   the wrong exit status can be caught.

More cosmetic changes:

 - put the opening quote starting each test on the same line as the
   test_expect_* invocation, and indent the commands in each test
   with a single tab

 - end the test early if the underlying filesystem cannot
   accomodate the filenames we use, instead of marking all tests
   with the same TABS_IN_FILENAMES prerequisite.

e7a8ac3875 test: use numstat instead of diffstat in funny-names test
This test script checks that git's plumbing commands quote filenames
with special characters like space, tab, and double-quote
appropriately in their input and output.

Since commit v1.7.9.2~13 (Use correct grammar in diffstat summary
line, 2012-02-01), the final "1 file changed, 1 insertion(+)" line
from diffstats is translatable, meaning tests that rely on exact "git
apply --stat" output have to be skipped when git is not configured to
produce output in the C locale (for example, when GETTEXT_POISON is
enabled).  So:

 - Tweak the three "git apply --stat" tests that check "git apply"'s
   input parsing to use --numstat instead.

   --numstat output is more reliable, does not vary with locale, and
   is itself easier to parse.  These tests are mainly about how "git
   apply" parses its input so this should not result in much loss of
   coverage.

 - Add a new "apply --stat" test to check the quoting in --stat output
   format.

This wins back a little of the test coverage lost with the patch
"test: use test_i18ncmp to check --stat output" when GETTEXT_POISON is
enabled.

7dfe8ad600 commit: pass author/committer info to hooks
When lying the author name via GIT_AUTHOR_NAME environment variable
to "git commit", the hooks run by the command saw it and could act
on the name that will be recorded in the final commit. When the user
uses the "--author" option from the command line, the command should
give the same information to the hook, and back when "git command"
was a scripted Porcelain, it did set the environment variable and
hooks can learn the author name from it.

However, when the command was reimplemented in C, the rewritten code
was not very faithful to the original, and hooks stopped getting the
authorship information given with "--author".  Fix this by exporting
the necessary environment variables.

178e1deaae fast-import: don't allow 'ls' of path with empty components
As the fast-import manual explains:

	The value of <path> must be in canonical form. That is it must
	not:
	. contain an empty directory component (e.g. foo//bar is invalid),
	. end with a directory separator (e.g. foo/ is invalid),
	. start with a directory separator (e.g. /foo is invalid),

Unfortunately the "ls" command accepts these invalid syntaxes and
responds by declaring that the indicated path is missing.  This is too
subtle and causes importers to silently misbehave; better to error out
so the operator knows what's happening.

The C, R, and M commands already error out for such paths.

9b9f46f5c1 t0204: clarify the "observe undefined behaviour" test
This test asks for an impossible conversion to the system by
preparing an UTF-8 translation with characters that cannot be
expressed in ISO-8859-1, and then asking the message shown in
ISO-8859-1.  Even though the behaviour against such a request is
undefined, it may be interesting to see what the system does, and
the purpose of this test is to see if there are platforms that
exhibit behaviour that we haven't seen.

The original recognized two known modes of behaviour:

 - the key used to query the message catalog ("TEST: Old English
   Runes"), saying "I cannot do that i18n".
 - impossible characters replaced with ASCII "?", saying "I punt".

but they were treated totally differently.  The test simply issued
an informational message "Your system punts on this one" for the
first error mode, while it diagnosed the latter as "Your system is
good; you pass!".

It turns out that Mac OS X exhibits a third mode of error behaviour,
to spew out the raw value stored in the message catalog.  The test
diagnosed this behaviour as "broken", but it is merely trying to do
its best to respond to an impossible request by saying "I punt" in a
way that is slightly different from the second one.

Update the offending test to make it clear what is (and is not)
being tested, update the code structure so that newly discovered
error mode can easily be added to it later, and reword the message
that comes from a failing case to clarify that it is not the system
that is broken when it fails, but merely that the behaviour is not
something we have seen.

Myers, while patience is much slower than the others.

The text about setting up a remote is superfluous and doesn't help

of the generic <remote>.

69c3051780 submodules: refactor computation of relative gitdir path
In module_clone() the rel_gitdir variable was computed differently when
"git rev-parse --git-dir" returned a relative path than when it returned
an absolute path. This is not optimal, as different code paths are used
depending on the return value of that command.

Fix that by reusing the differing path components computed for setting the
core.worktree config setting, which leaves a single code path for setting
both instead of having three and makes the code much shorter.

This also fixes the bug that in the computation of how many directories
have to be traversed up to hit the root directory of the submodule the
name of the submodule was used where the path should have been used. This
lead to problems after renaming submodules into another directory level.

Even though the "(cd $somewhere && pwd)" approach breaks the flexibility
of symlinks, that is no issue here as we have to have one relative path
pointing from the work tree to the gitdir and another pointing back, which
will never work anyway when a symlink along one of those paths is changed
because the directory it points to was moved.

Also add a test moving a submodule into a deeper directory to catch any
future breakage here and to document what has to be done when a submodule
needs to be moved until git mv learns to do that. Simply moving it to the
new location doesn't work, as the core.worktree and possibly the gitfile
setting too will be wrong. So it has to be removed from filesystem and
index, then the new location has to be added into the index and the
.gitmodules file has to be updated. After that a git submodule update will
check out the submodule at the new location.

d75219b4a8 submodules: always use a relative path from gitdir to work tree
Since recently a submodule with name <name> has its git directory in the
.git/modules/<name> directory of the superproject while the work tree
contains a gitfile pointing there. To make that work the git directory has
the core.worktree configuration set in its config file to point back to
the work tree.

That core.worktree is an absolute path set by the initial clone of the
submodule. A relative path is preferable here because it allows the
superproject to be moved around without invalidating that setting, so
compute and set that relative path after cloning or reactivating the
submodule.

This also fixes a bug when moving a submodule around inside the
superproject, as the current code forgot to update the setting to the new
submodule work tree location.

Enhance t7400 to ensure that future versions won't re-add absolute paths
by accident and that moving a superproject won't break submodules.

ea115a0d43 submodules: always use a relative path to gitdir
Since recently a submodule with name <name> has its git directory in the
.git/modules/<name> directory of the superproject while the work tree
contains a gitfile pointing there. When the submodule git directory needs
to be cloned because it is not found in .git/modules/<name> the clone
command will write an absolute path into the gitfile. When no clone is
necessary the git directory will be reactivated by the git-submodule.sh
script by writing a relative path into the gitfile.

This is inconsistent, as the behavior depends on the submodule having been
cloned before into the .git/modules of the superproject. A relative path
is preferable here because it allows the superproject to be moved around
without invalidating the gitfile. We do that by always writing the
relative path into the gitfile, which overwrites the absolute path the
clone command may have written there.

This is only the first step to make superprojects movable again like they
were before the separate-git-dir approach was introduced. The second step
is to use a relative path in core.worktree too.

Enhance t7400 to ensure that future versions won't re-add absolute paths
by accident.

While at it also replace an if/else construct evaluating the presence
of the 'reference' option with a single line of bash code.

78ed1d2d63 t0300: work around bug in dash 0.5.6
The construct 'while IFS== read' makes dash 0.5.6 execute
read without changing IFS, which results in test breakages
all over the place in t0300.  Neither dash 0.5.5.1 and older
nor dash 0.5.7 and newer are affected: The problem was
introduded resp. fixed by the commits

  55c46b7 ([BUILTIN] Honor tab as IFS whitespace when
           splitting fields in readcmd, 2009-08-11)

  1d806ac ([VAR] Do not poplocalvars prematurely on regular
           utilities, 2010-05-27)

in http://git.kernel.org/?p=utils/dash/dash.git

Putting 'IFS==' before that line makes all versions of dash
work.

This looks like a dash bug, not a misinterpretation of the
standard. However, it's worth working around for two
reasons. One, this version of dash was released in Fedora
14-16, so the bug is found in the wild. And two, at least
one other shell, Solaris /bin/sh, choked on this by
persisting IFS after the read invocation. That is not a
shell we usually care about, and I think this use of IFS is
acceptable by POSIX (which allows other behavior near
"special builtins", but "read" is not one of those). But it
seems that this may be a subtle, not-well-tested case for
some shells. Given that the workaround is so simple, it's
worth just being defensive.

 - Prefer 'test_line_count = COUNT FILE' over 'test $(wc -l <FILE) = COUNT'

 - Prefer 'test_line_count = 0 FILE' over 'cmp -s /dev/null FILE'

 - Use '<<-EOF' style for here documents, so that they can be indented

efe4be1249 bundle: keep around names passed to add_pending_object()
The 'name' field passed to add_pending_object() is used to later
deduplicate in object_array_remove_duplicates().

git-bundle had a bug in this area since 18449ab (git-bundle: avoid
packing objects which are in the prerequisites, 2007-03-08): it passed
the name of each boundary object in a static buffer.  In other words,
all that object_array_remove_duplicates() saw was the name of the
*last* added boundary object.

The recent switch to a strbuf in bc2fed4 (bundle: use a strbuf to scan
the log for boundary commits, 2012-02-22) made this slightly worse: we
now free the buffer at the end, so it is not even guaranteed that it
still points into addressable memory by the time object_array_remove_
duplicates looks at it.  On the plus side however, it was now
detectable by valgrind.

The fix is easy: pass a copy of the string to add_pending_object.

b3f01ff29f diff -p: squelch "diff --git" header for stat-dirty paths
The plumbing "diff" commands look at the working tree files without
refreshing the index themselves for performance reasons (the calling
script is expected to do that upfront just once, before calling one or
more of them).  In the early days of git, they showed the "diff --git"
header before they actually ask the xdiff machinery to produce patches,
and ended up showing only these headers if the real contents are the same
and the difference they noticed was only because the stat info cached in
the index did not match that of the working tree. It was too late for the
implementation to take the header that it already emitted back.

But 3e97c7c (No diff -b/-w output for all-whitespace changes, 2009-11-19)
introduced necessary logic to keep the meta-information headers in a
strbuf and delay their output until the xdiff machinery noticed actual
changes. This was primarily in order to generate patches that ignore
whitespaces. When operating under "-w" mode, we wouldn't know if the
header is needed until we actually look at the resulting patch, so it was
a sensible thing to do, but we did not realize that the same reasoning
applies to stat-dirty paths.

Later, 296c6bb (diff: fix "git show -C -C" output when renaming a binary
file, 2010-05-26) generalized this machinery and added must_show_header
toggle.  This is turned on when the header must be shown even when there
is no patch to be produced, e.g. only the mode was changed, or the path
was renamed, without changing the contents.  However, when it did so, it
still kept the special case for the "-w" mode, which meant that the
plumbing would keep showing these phantom changes.

This corrects this historical inconsistency by allowing the plumbing to
omit paths that are only stat-dirty from its output in the same way as it
handles whitespace only changes under "-w" option.

The change in the behaviour can be seen in the updated test.

5597e84b51 t4011: illustrate "diff-index -p" on stat-dirty paths
The plumbing that looks at the working tree, i.e. "diff-index" and
"diff-files", always emit the "diff --git a/path b/path" header lines
without anything else for paths that are only stat-dirty (i.e. different
only because the cached stat information in the index no longer matches
that of the working tree, but the real contents are the same), when
these commands are run with "-p" option to produce patches.

Illustrate this current behaviour.  Also demonstrate that with the "-w"
option, we (correctly) hold off showing a "diff --git" header until actual
differences have been found.  This also suppresses the header for merely
stat-dirty files, which is inconsistent.

 - Prepare the expected output inside your own test.

 - The order of comparison to check the result is "diff expected actual",

For the graph-width limiting to be usable, it should happen

The way that available columns are divided between the filename part
and the graph part is modified to use as many columns as necessary for
the filenames and the rest for the graph.

If there isn't enough columns to print both the filename and the
graph, at least 5/8 of available space is devoted to filenames. On a
standard 80 column terminal, or if not connected to a terminal and
using the default of 80 columns, this gives the same partition as
before.

The effect of this change is visible in the patch to the test vector
in t4052; with a small change with long filename, it stops truncating
the name part too short, and also allocates a bit more columns to the
graph for larger changes.

af9fedc128 diff --stat: use the full terminal width
Default to the real terminal width for diff --stat output, instead
of the hard-coded 80 columns.

Some projects (especially in Java), have long filename paths, with
nested directories or long individual filenames. When files are
renamed, the filename part in stat output can be almost useless. If
the middle part between { and } is long (because the file was moved to
a completely different directory), then most of the path would be
truncated.

It makes sense to detect and use the full terminal width and display
full filenames if possible.

The are commands like diff, show, and log, which can adapt the output
to the terminal width. There are also commands like format-patch,
whose output should be independent of the terminal width. Since it is
safer to use the 80-column default, the real terminal width is only
used if requested by the calling code by setting diffopts.stat_width=-1.
Normally this value is 0, and can be set by the user only to a
non-negative value, so -1 is safe to use internally.

This patch only changes the diff builtin to use the full terminal width.

When a pathname is so long that it cannot fit on the column, the current

changed), this results in the final output that is shorter than the width

accccde483 pickaxe: allow -i to search in patch case-insensitively
"git log -S<string>" is a useful way to find the last commit in the
codebase that touched the <string>. As it was designed to be used by a
porcelain script to dig the history starting from a block of text that
appear in the starting commit, it never had to look for anything but an
exact match.

When used by an end user who wants to look for the last commit that
removed a string (e.g. name of a variable) that he vaguely remembers,
however, it is useful to support case insensitive match.

When given the "--regexp-ignore-case" (or "-i") option, which originally

c6a13b2c86 fsck: --no-dangling omits "dangling object" information
The default output from "fsck" is often overwhelmed by informational
message on dangling objects, especially if you do not repack often, and a
real error can easily be buried.

Add "--no-dangling" option to omit them, and update the user manual to
demonstrate its use.

Based on a patch by Clemens Buchacher, but reverted the part to change
the default to --no-dangling, which is unsuitable for the first patch.
The usual three-step procedure to break the backward compatibility over
time needs to happen on top of this, if we were to go in that direction.

36612e4daf gitweb: Handle invalid regexp in regexp search
When using regexp search ('sr' parameter / $search_use_regexp variable
is true), check first that regexp is valid.

Without this patch we would get an error from Perl during search (if
searching is performed by gitweb), or highlighting matches substring
(if applicable), if user provided invalid regexp... which means broken
HTML, with error page (including HTTP headers) generated after gitweb
already produced some output.

Add test that illustrates such error: for example for regexp "*\.git"
we would get the following error:

  Quantifier follows nothing in regex; marked by <-- HERE in m/* <-- HERE \.git/
  at /var/www/cgi-bin/gitweb.cgi line 3084.

print_ref_list looks up the merge_filter_ref and assumes that a valid

When the --use-client-spec is given to clone, and the clone
path is a subset of the full tree as specified in the client,
future submits will go to the wrong place.

Factor out getClientSpec() so both clone/sync and submit can
use it.  Introduce getClientRoot() that is needed for the client
spec case, and use it instead of p4Where().

Test the five possible submit behaviors (add, modify, rename,
copy, delete).

0f1930c587 parse-options: allow positivation of options starting, with no-
Long options can be negated by adding no- right after the leading
two dashes. This is useful e.g. to override options set by aliases.

For options that are defined to start with no- already, this looks
a bit funny. Allow such options to also be negated by removing the
prefix.

The following thirteen options are affected:

	apply          --no-add
	bisect--helper --no-checkout
	checkout-index --no-create
	clone          --no-checkout --no-hardlinks
	commit         --no-verify   --no-post-rewrite
	format-patch   --no-binary
	hash-object    --no-filters
	read-tree      --no-sparse-checkout
	revert         --no-commit
	show-branch    --no-name
	update-ref     --no-deref

The following five are NOT affected because they are defined with
PARSE_OPT_NONEG or the non-negated version is defined as well:

	branch       --no-merged
	format-patch --no-stat             --no-numbered
	update-index --no-assume-unchanged --no-skip-worktree

4f22b1015d do not stream large files to pack when filters are in use
Because git's object format requires us to specify the
number of bytes in the object in its header, we must know
the size before streaming a blob into the object database.
This is not a problem when adding a regular file, as we can
get the size from stat(). However, when filters are in use
(such as autocrlf, or the ident, filter, or eol
gitattributes), we have no idea what the ultimate size will
be.

The current code just punts on the whole issue and ignores
filter configuration entirely for files larger than
core.bigfilethreshold. This can generate confusing results
if you use filters for large binary files, as the filter
will suddenly stop working as the file goes over a certain
size.  Rather than try to handle unknown input sizes with
streaming, this patch just turns off the streaming
optimization when filters are in use.

This has a slight performance regression in a very specific
case: if you have autocrlf on, but no gitattributes, a large
binary file will avoid the streaming code path because we
don't know beforehand whether it will need conversion or
not. But if you are handling large binary files, you should
be marking them as such via attributes (or at least not
using autocrlf, and instead marking your text files as
such). And the flip side is that if you have a large
_non_-binary file, there is a correctness improvement;
before we did not apply the conversion at all.

The first half of the new t1051 script covers these failures
on input. The second half tests the matching output code
paths. These already work correctly, and do not need any
adjustment.

8a557bb77f t5704: match tests to modern style
The test did not adhere to the current style on several counts:

 . empty lines around the test blocks, but within the test string
 . ': > file' or even just '> file' with an extra space
 . inconsistent indentation
 . hand-rolled commits instead of using test_commit

Fix all of them.

There's a catch to the last point: test_commit creates a tag, which the
original test did not create.  We still change it to test_commit, and
explicitly delete the tags, so as to highlight that the test relies on not
having them.

60df071c6c git-p4: add initial support for RCS keywords
RCS keywords cause problems for git-p4 as perforce always
expands them (if +k is set) and so when applying the patch,
git reports that the files have been modified by both sides,
when in fact they haven't.

This change means that when git-p4 detects a problem applying
a patch, it will check to see if keyword expansion could be
the culprit. If it is, it strips the keywords in the p4
repository so that they match what git is expecting. It then
has another go at applying the patch.

This behaviour is enabled with a new git-p4 configuration
option and is off by default.

bc2fed496b bundle: use a strbuf to scan the log for boundary commits
The first part of the bundle header contains the boundary commits, and
could be approximated by

  # v2 git bundle
  $(git rev-list --pretty=oneline --boundary <ARGS> | grep ^-)

git-bundle actually spawns exactly this rev-list invocation, and does
the grepping internally.

There was a subtle bug in the latter step: it used fgets() with a
1024-byte buffer.  If the user has sufficiently long subjects (e.g.,
by not adhering to the git oneline-subject convention in the first
place), the 'oneline' format can easily overflow the buffer.  fgets()
then returns the rest of the line in the next call(s).  If one of
these remaining parts started with '-', git-bundle would mistakenly
insert it into the bundle thinking it was a boundary commit.

Fix it by using strbuf_getwholeline() instead, which handles arbitrary
line lengths correctly.

Note that on the receiving side in parse_bundle_header() we were
already using strbuf_getwholeline_fd(), so that part is safe.

open_or_add_dir checks to see if the directory already exists or not.
If it already exists and is not a directory, then we fail.  However,
open_or_add_dir did not previously account for the possibility that the
path did exist as a file, but is deleted in the current commit.

In order to prevent this legitimate case from failing, open_or_add_dir
needs to know what files are deleted in the current commit.
Unfortunately that information has to be plumbed through a couple of
layers.

fc8fcd27e6 gitweb: Fix 'grep' search for multiple matches in file
Commit ff7f218 (gitweb: Fix file links in "grep" search, 2012-01-05),
added $file_href variable, to reduce duplication and have the fix
applied in single place.

Unfortunately it made variable defined inside the loop, not taking into
account the fact that $file_href was set only if file changed.
Therefore for files with multiple matches $file_href was undefined for
second and subsequent matches.

Fix this bug by moving $file_href declaration outside loop.

Adds tests for almost all forms of sarch in gitweb, which were missing
from testuite.  Note that it only tests if there are no warnings, and
it doesn't check that gitweb finds what it should find.

3d1f148c33 refresh_index: do not show unmerged path that is outside pathspec
When running "git add --refresh <pathspec>", we incorrectly showed the
path that is unmerged even if it is outside the specified pathspec, even
though we did honor pathspec and refreshed only the paths that matched.

Note that this cange does not affect "git update-index --refresh"; for
hysterical raisins, it does not take a pathspec (it takes real paths) and
more importantly itss command line options are parsed and executed one by
one as they are encountered, so "git update-index --refresh foo" means
"first refresh the index, and then update the entry 'foo' by hashing the
contents in file 'foo'", not "refresh only entry 'foo'".

fd49e56af6 gitweb: Fix "heads" view when there is no current branch
In a repository whose HEAD points to an unborn branch with no commits,
"heads" view and "summary" view (which shows what is shown in "heads"
view) compared the object names of commits at the tip of branches with the
output from "git rev-parse HEAD", which caused comparison of a string with
undef and resulted in a warning in the server log.

This can happen if non-bare repository (with default 'master' branch)
is updated not via committing but by other means like push to it, or
Gerrit.  It can happen also just after running "git checkout --orphan
<new branch>" but before creating any new commit on this branch.

Rewrite the comparison so that it also works when $head points at nothing;
in such a case, no branch can be "the current branch", add a test for it.
While at it, rename local variable $head to $head_at, as it points to
current commit rather than current branch name (HEAD contents).

The code still incorrectly shows all branches that point at the same
commit as what HEAD points as "the current branch", even when HEAD is
detached. Fixing this bug is outside the scope of this patch.

342e9ef2d9 Introduce a performance testing framework
This introduces a performance testing framework under t/perf/.  It
tries to be as close to the test-lib.sh infrastructure as possible,
and thus should be easy to get used to for git developers.

The following points were considered for the implementation:

1. You usually want to compare arbitrary revisions/build trees against
   each other.  They may not have the performance test under
   consideration, or even the perf-lib.sh infrastructure.

   To cope with this, the 'run' script lets you specify arbitrary
   build dirs and revisions.  It even automatically builds the revisions
   if it doesn't have them at hand yet.

2. Usually you would not want to run all tests.  It would take too
   long anyway.  The 'run' script lets you specify which tests to run;
   or you can also do it manually.  There is a Makefile for
   discoverability and 'make clean', but it is not meant for
   real-world use.

3. Creating test repos from scratch in every test is extremely
   time-consuming, and shipping or downloading such large/weird repos
   is out of the question.

   We leave this decision to the user.  Two different sizes of test
   repos can be configured, and the scripts just copy one or more of
   those (using hardlinks for the object store).  By default it tries
   to use the build tree's git.git repository.

   This is fairly fast and versatile.  Using a copy instead of a clone
   preserves many properties that the user may want to test for, such
   as lots of loose objects, unpacked refs, etc.

9b25a0b52e config: add include directive
It can be useful to split your ~/.gitconfig across multiple
files. For example, you might have a "main" file which is
used on many machines, but a small set of per-machine
tweaks. Or you may want to make some of your config public
(e.g., clever aliases) while keeping other data back (e.g.,
your name or other identifying information). Or you may want
to include a number of config options in some subset of your
repos without copying and pasting (e.g., you want to
reference them from the .git/config of participating repos).

This patch introduces an include directive for config files.
It looks like:

  [include]
    path = /path/to/file

This is syntactically backwards-compatible with existing git
config parsers (i.e., they will see it as another config
entry and ignore it unless you are looking up include.path).

The implementation provides a "git_config_include" callback
which wraps regular config callbacks. Callers can pass it to
git_config_from_file, and it will transparently follow any
include directives, passing all of the discovered options to
the real callback.

Include directives are turned on automatically for "regular"
git config parsing. This includes calls to git_config, as
well as calls to the "git config" program that do not
specify a single file (e.g., using "-f", "--global", etc).
They are not turned on in other cases, including:

  1. Parsing of other config-like files, like .gitmodules.
     There isn't a real need, and I'd rather be conservative
     and avoid unnecessary incompatibility or confusion.

  2. Reading single files via "git config". This is for two
     reasons:

       a. backwards compatibility with scripts looking at
          config-like files.

       b. inspection of a specific file probably means you
	  care about just what's in that file, not a general
          lookup for "do we have this value anywhere at
	  all". If that is not the case, the caller can
	  always specify "--includes".

  3. Writing files via "git config"; we want to treat
     include.* variables as literal items to be copied (or
     modified), and not expand them. So "git config
     --unset-all foo.bar" would operate _only_ on
     .git/config, not any of its included files (just as it
     also does not operate on ~/.gitconfig).

270a34438b config: stop using config_exclusive_filename
The git-config command sometimes operates on the default set
of config files (either reading from all, or writing to repo
config), and sometimes operates on a specific file. In the
latter case, we set the magic global config_exclusive_filename,
and the code in config.c does the right thing.

Instead, let's have git-config use the "advanced" variants
of config.c's functions which let it specify an individual
filename (or NULL for the default). This makes the code a
lot more obvious, and fixes two small bugs:

  1. A relative path specified by GIT_CONFIG=foo will look
     in the wrong directory if we have to chdir as part of
     repository setup. We already handle this properly for
     "git config -f foo", but the GIT_CONFIG lookup used
     config_exclusive_filename directly. By dropping to a
     single magic variable, the GIT_CONFIG case now just
     works.

  2. Calling "git config -f foo --edit" would not respect
     core.editor. This is because just before editing, we
     called git_config, which would respect the
     config_exclusive_filename setting, even though this
     particular git_config call was not about looking in the
     user's specified file, but rather about loading actual
     git config, just as any other git program would.

36daaaca00 Add a setting to require a filter to be successful
By default, a missing filter driver or a failure from the filter driver is
not an error, but merely makes the filter operation a no-op pass through.
This is useful to massage the content into a shape that is more convenient
for the platform, filesystem, and the user to use, and the content filter
mechanism is not used to turn something unusable into usable.

However, we could also use of the content filtering mechanism and store
the content that cannot be directly used in the repository (e.g. a UUID
that refers to the true content stored outside git, or an encrypted
content) and turn it into a usable form upon checkout (e.g. download the
external content, or decrypt the encrypted content).  For such a use case,
the content cannot be used when filter driver fails, and we need a way to
tell Git to abort the whole operation for such a failing or missing filter
driver.

Add a new "filter.<driver>.required" configuration variable to mark the
second use case.  When it is set, git will abort the operation when the
filter driver does not exist or exits with a non-zero status code.

ef7e93d908 do not override receive-pack errors
Receive runs rev-list --verify-objects in order to detect missing
objects. However, such errors are ignored and overridden later.
Instead, consequently ignore all update commands for which an error has
already been detected.

Some tests in t5504 are obsoleted by this change, because invalid
objects are detected even if fsck is not enabled. Instead, they now test
for different error messages depending on whether or not fsck is turned
on. A better fix would be to force a corruption that will be detected by
fsck but not by rev-list.

31fd8d72f2 tag: do not show non-tag contents with "-n"
"git tag -n" did not check the type of the object it is reading the top n
lines from. At least, avoid showing the beginning of trees and blobs when
dealing with lightweight tags that point at them.

As the payload of a tag and a commit look similar in that they both start
with a header block, which is skipped for the purpose of "-n" output,
followed by human readable text, allow the message of commit objects to be
shown just like the contents of tag objects. This avoids regression for
people who have been using "tag -n" to show the log messages of commits
that are pointed at by lightweight tags.

Test script is from Jeff King.

3f6d56de5f commit: ignore intent-to-add entries instead of refusing
Originally, "git add -N" was introduced to help users from forgetting to
add new files to the index before they ran "git commit -a".  As an attempt
to help them further so that they do not forget to say "-a", "git commit"
to commit the index as-is was taught to error out, reminding the user that
they may have forgotten to add the final contents of the paths before
running the command.

This turned out to be a false "safety" that is useless.  If the user made
changes to already tracked paths and paths added with "git add -N", and
then ran "git add" to register the final contents of the paths added with
"git add -N", "git commit" will happily create a commit out of the index,
without including the local changes made to the already tracked paths. It
was not a useful "safety" measure to prevent "forgetful" mistakes from
happening.

It turns out that this behaviour is not just a useless false "safety", but
actively hurts use cases of "git add -N" that were discovered later and
have become popular, namely, to tell Git to be aware of these paths added
by "git add -N", so that commands like "git status" and "git diff" would
include them in their output, even though the user is not interested in
including them in the next commit they are going to make.

Fix this ancient UI mistake, and instead make a commit from the index
ignoring the paths added by "git add -N" without adding real contents.

Based on the work by Nguyễn Thái Ngọc Duy, and helped by injection of
sanity from Jonathan Nieder and others on the Git mailing list.

abe199808c git checkout -b: allow switching out of an unborn branch
Running "git checkout -b another" immediately after "git init" when you do
not even have a commit on 'master' fails with:

    $ git checkout -b another
    fatal: You are on a branch yet to be born

This is unnecessary, if we redefine "git checkout -b $name" that does not
take any $start_point (which has to be a commit) as "I want to check out a
new branch $name from the state I am in".

c2d17ba3db branch --edit-description: protect against mistyped branch name
It is very easy to mistype the branch name when editing its description,
e.g.

	$ git checkout -b my-topic master
	: work work work
	: now we are at a good point to switch working something else
	$ git checkout master
	: ah, let's write it down before we forget what we were doing
	$ git branch --edit-description my-tpoic

The command does not notice that branch 'my-tpoic' does not exist.  It is
not lost (it becomes description of an unborn my-tpoic branch), but is not
very useful.  So detect such a case and error out to reduce the grief
factor from this common mistake.

This incidentally also errors out --edit-description when the HEAD points
at an unborn branch (immediately after "init", or "checkout --orphan"),
because at that point, you do not even have any commit that is part of
your history and there is no point in describing how this particular
branch is different from the branch it forked off of, which is the useful
bit of information the branch description is designed to capture.

We may want to special case the unborn case later, but that is outside the
scope of this patch to prevent more common mistakes before 1.7.9 series
gains too much widespread use.

b5c9f1c1b0 merge: do not create a signed tag merge under --ff-only option
Starting at release v1.7.9, if you ask to merge a signed tag, "git merge"
always creates a merge commit, even when the tag points at a commit that
happens to be a descendant of your current commit.

Unfortunately, this interacts rather badly for people who use --ff-only to
make sure that their branch is free of local developments. It used to be
possible to say:

	$ git checkout -b frotz v1.7.9~30
        $ git merge --ff-only v1.7.9

and expect that the resulting tip of frotz branch matches v1.7.9^0 (aka
the commit tagged as v1.7.9), but this fails with the updated Git with:

	fatal: Not possible to fast-forward, aborting.

because a merge that merges v1.7.9 tag to v1.7.9~30 cannot be created by
fast forwarding.

We could teach users that now they have to do

	$ git merge --ff-only v1.7.9^0

but it is far more pleasant for users if we DWIMmed this ourselves.

When an integrator pulls in a topic from a lieutenant via a signed tag,
even when the work done by the lieutenant happens to fast-forward, the
integrator wants to have a merge record, so the integrator will not be
asking for --ff-only when running "git pull" in such a case. Therefore,
this change should not regress the support for the use case v1.7.9 wanted
to add.

2c733fb24c parse_date(): '@' prefix forces git-timestamp
The only place that the issue this series addresses was observed
where we read "cat-file commit" output and put it in GIT_AUTHOR_DATE
in order to replay a commit with an ancient timestamp.

With the previous patch alone, "git commit --date='20100917 +0900'"
can be misinterpreted to mean an ancient timestamp, not September in
year 2010.  Guard this codepath by requring an extra '@' in front of
the raw git timestamp on the parsing side. This of course needs to
be compensated by updating get_author_ident_from_commit and the code
for "git commit --amend" to prepend '@' to the string read from the
existing commit in the GIT_AUTHOR_DATE environment variable.

"!/bin/sh". Even though the scripts are fairly simple, they
can fail on broken shells (specifically, Solaris /bin/sh
will persist a temporary assignment to IFS in a "read"

Rather than work around the problem for Solaris /bin/sh,
using write_script will make sure we point to a known-good

840c519d7e tests: add write_script helper function
Many of the scripts in the test suite write small helper
shell scripts to disk. It's best if these shell scripts
start with "#!$SHELL_PATH" rather than "#!/bin/sh", because
/bin/sh on some platforms is too buggy to be used.

However, it can be cumbersome to expand $SHELL_PATH, because
the usual recipe for writing a script is:

	cat >foo.sh <<-\EOF
	#!/bin/sh
	echo my arguments are "$@"
	EOF

To expand $SHELL_PATH, you have to either interpolate the
here-doc (which would require quoting "\$@"), or split the
creation into two commands (interpolating the $SHELL_PATH
line, but not the rest of the script). Let's provide a
helper function that makes that less syntactically painful.

While we're at it, this helper can also take care of the
"chmod +x" that typically comes after the creation of such a
script, saving the caller a line.

b3256eb8b3 standardize and improve lookup rules for external local repos
When you specify a local repository on the command line of
clone, ls-remote, upload-pack, receive-pack, or upload-archive,
or in a request to git-daemon, we perform a little bit of
lookup magic, doing things like looking in working trees for
.git directories and appending ".git" for bare repos.

For clone, this magic happens in get_repo_path. For
everything else, it happens in enter_repo. In both cases,
there are some ambiguous or confusing cases that aren't
handled well, and there is one case that is not handled the
same by both methods.

This patch tries to provide (and test!) standard, sensible
lookup rules for both code paths. The intended changes are:

  1. When looking up "foo", we have always preferred
     a working tree "foo" (containing "foo/.git" over the
     bare "foo.git". But we did not prefer a bare "foo" over
     "foo.git". With this patch, we do so.

  2. We would select directories that existed but didn't
     actually look like git repositories. With this patch,
     we make sure a selected directory looks like a git
     repo. Not only is this more sensible in general, but it
     will help anybody who is negatively affected by change
     (1) negatively (e.g., if they had "foo.git" next to its
     separate work tree "foo", and expect to keep finding
     "foo.git" when they reference "foo").

  3. The enter_repo code path would, given "foo", look for
     "foo.git/.git" (i.e., do the ".git" append magic even
     for a repo with working tree). The clone code path did
     not; with this patch, they now behave the same.

In the unlikely case of a working tree overlaying a bare
repo (i.e., a ".git" directory _inside_ a bare repo), we
continue to treat it as a working tree (prefering the
"inner" .git over the bare repo). This is mainly because the
combination seems nonsensical, and I'd rather stick with
existing behavior on the off chance that somebody is relying
on it.

41b59bfcb1 grep: respect diff attributes for binary-ness
There is currently no way for users to tell git-grep that a
particular path is or is not a binary file; instead, grep
always relies on its auto-detection (or the user specifying
"-a" to treat all binary-looking files like text).

This patch teaches git-grep to use the same attribute lookup
that is used by git-diff. We could add a new "grep" flag,
but that is unnecessarily complex and unlikely to be useful.
Despite the name, the "-diff" attribute (or "diff=foo" and
the associated diff.foo.binary config option) are really
about describing the contents of the path. It's simply
historical that diff was the only thing that cared about
these attributes in the past.

And if this simple approach turns out to be insufficient, we
still have a backwards-compatible path forward: we can add a
separate "grep" attribute, and fall back to respecting
"diff" if it is unset.

2ad9ba0382 request-pull: explicitly ask tags/$name to be pulled
When asking for a tag to be pulled, disambiguate by leaving tags/ prefix

    ... in the git repository at:

      git://example.com/git/git.git/ tags/v1.2.3

    for you to fetch changes up to 123456...

This way, older versions of "git pull" can be used to respond to such a
request more easily, as "git pull $URL v1.2.3" did not DWIM to fetch
v1.2.3 tag in older versions. Also this makes it clearer for humans that
the pull request is made for a tag and he should anticipate a signed one.

test_must_fail is to make sure a program we can potentially break during
the course of updating git itself exits with a non-zero status in a clean
and controlled way.

When we expect a non-zero exit status from the commands we use from the
underlying platform in tests, e.g. making sure a string "error: " does not
appear in the output by running "grep 'error: '", just use "! grep" for
readability. It is not like we will try to update Git and suddenly 'grep'
we use from the system starts segfaulting.

1017c1abcb submodule add: fix breakage when re-adding a deep submodule
Since recently a submodule with name <name> has its git directory in the
.git/modules/<name> directory of the superproject while the work tree
contains a gitfile pointing there.

When the same submodule is added on a branch where it wasn't present so
far (it is not found in the .gitmodules file), the name is not initialized
from the path as it should. This leads to a wrong path entered in the
gitfile when the .git/modules/<name> directory is found, as this happily
uses the - now empty - name. It then always points only a single directory
up, even if we have a path deeper in the directory hierarchy.

Fix that by initializing the name of the submodule early in module_clone()
if module_name() returned an empty name and add a test to catch that bug.

f8246281af merge: use editor by default in interactive sessions
Traditionally, a cleanly resolved merge was committed by "git merge" using
the auto-generated merge commit log message without invoking the editor.

After 5 years of use in the field, it turns out that people perform too
many unjustified merges of the upstream history into their topic branches.
These merges are not just useless, but they are often not explained well,
and making the end result unreadable when it gets time for merging their
history back to their upstream.

Earlier we added the "--edit" option to the command, so that people can
edit the log message to explain and justify their merge commits. Let's
take it one step further and spawn the editor by default when we are in an
interactive session (i.e. the standard input and the standard output are
pointing at the same tty device).

There may be existing scripts that leave the standard input and the
standard output of the "git merge" connected to whatever environment the
scripts were started, and such invocation might trigger the above
"interactive session" heuristics.  GIT_MERGE_AUTOEDIT environment variable
can be set to "no" at the beginning of such scripts to use the historical
behaviour while the script runs.

Note that this backward compatibility is meant only for scripts, and we
deliberately do *not* support "merge.edit = yes/no/auto" configuration
option to allow people to keep the historical behaviour.

ec245ba049 mergetool: Provide an empty file when needed
Some merge tools cannot cope when $LOCAL, $BASE, or $REMOTE are missing.
$BASE can be missing when two branches independently add the same
filename.

Provide an empty file to make these tools happy.

When a delete/modify conflict occurs, $LOCAL and $REMOTE can also be
missing. We have special case code to handle such case so this change
may not affect that codepath, but try to be consistent and create an
empty file for them anyway.

50dd0f2fd9 grep: fix -l/-L interaction with decoration lines
In threaded mode, git-grep emits file breaks (enabled with context, -W
and --break) into the accumulation buffers even if they are not
required.  The output collection thread then uses skip_first_line to
skip the first such line in the output, which would otherwise be at
the very top.

This is wrong when the user also specified -l/-L/-c, in which case
every line is relevant.  While arguably giving these options together
doesn't make any sense, git-grep has always quietly accepted it.  So
do not skip anything in these cases.

aae5239be2 t/Makefile: Use $(sort ...) explicitly where needed
Starting from GNU Make 3.82 $(wildcard ...) no longer sorts the result
(from NEWS):

    * WARNING: Backward-incompatibility!
      Wildcards were not documented as returning sorted values, but the results
      have been sorted up until this release..  If your makefiles require sorted
      results from wildcard expansions, use the $(sort ...)  function to request
      it explicitly.

    2a59dc32aa

I usually watch test progress visually, and if tests are sorted, even
with make -j4 they go more or less incrementally by their t number. On
the other side, without sorting, tests are executed in seemingly random
order even for -j1. Let's please maintain sane tests order for perceived
prettyness.

Another note is that in GNU Make sort also works as uniq, so after sort
being removed, we might expect e.g. $(wildcard *.sh a.*) to produce
duplicates for e.g. "a.sh". From this point of view, adding sort could
be seen as hardening t/Makefile from accidentally introduced dups.

It turned out that prevous releases of GNU Make did not perform full
sort in $(wildcard), only sorting results for each pattern, that's why
explicit sort-as-uniq is relevant even for older makes.

a080558ed7 git-p4: label import fails with multiple labels at the same changelist
git-p4 has an array of changelists with one label per changelist.
But you can have multiple labels on a single changelist and so this
code fails.

Add a test case demonstrating the problem.
