merge-recursive: Do not look at working tree during a virtual ancestor merge
Fix another instance of a recursive merge incorrectly paying attention to
the working tree file during a virtual ancestor merge, that resulted in
spurious and useless "addinfo_cache failed" error message.
When running git describe --dirty the index should be refreshed. Previously
the cached index would cause describe to think that the index was dirty when,
in reality, it was just stale.
The issue was exposed by python setuptools which hardlinks files into another
directory when building a distribution.
t4014: clean up format.thread config after each test
The threading tests turn on format.thread, but never clean
up after themselves, meaning that later tests will also have
format.thread set.
This is more annoying than most leftover config, too,
because not only does it impact the results of other tests,
but it does so non-deterministically. Threading requires the
generation of message-ids, which incorporate the current
time, meaning a slow-running test script may generate
different results from run to run.

The "git branch" command, while not in listing mode, calls create_branch()
even when the target branch already exists, and it does so even when it is
not interested in updating the value of the branch (i.e. the name of the
commit object that sits at the tip of the existing branch). This happens
when the command is run with "--set-upstream" option.
The earlier safety-measure to prevent "git branch -f $branch $commit" from
updating the currently checked out branch did not take it into account,
and we no longer can update the tracking information of the current branch.
Minimally fix this regression by telling the validation code if it is
called to really update the value of a potentially existing branch, or if
the caller merely is interested in updating auxiliary aspects of a branch.

Allow git-svn to populate the svn:mergeinfo property automatically in
a narrow range of circumstances. Specifically, when dcommitting a
revision with multiple parents, all but (potentially) the first of
which have been committed to SVN in the same repository as the target
of the dcommit.
In this case, the merge info is the union of that given by each of the
parents, plus all changes introduced to the first parent by the other
parents.
In all other cases where a revision to be committed has multiple
parents, cause "git svn dcommit" to raise an error rather than
completing the commit and potentially losing history information in
the upstream SVN repository.
This behavior is disabled by default, and can be enabled by setting
the svn.pushmergeinfo config option.

patches when color.ui is set to "always".
In f3aafa4 (Disable color detection during format-patch, 2006-07-09),
git_format_config was taught to intercept diff.color to avoid passing it
down to git_log_config and later, git_diff_ui_config.

Adding a new command line option to receive-pack and feed it from

Documentation/remote-helpers: explain capabilities first
The current remote helper documentation is from the perspective of
git, so to speak: it presents a full menu of commands for a person
invoking a remote helper to choose from. In practice, that's less
useful than it could be, since the daunted novice remote-helper author
probably just wanted a list of commands needs to implement to get
started. So preface the command list with an overview of each
capability, its purpose, and what commands it requires.
As a side effect, this makes it a little clearer that git doesn't
choose arbitrary commands to run, even if the remote helper advertises
all capabilities --- instead, there are well defined command sequences
for various tasks.

strbuf_grow(): maintain nul-termination even for new buffer
In the case where sb is initialized to the slopbuf (through
strbuf_init(sb,0) or STRBUF_INIT), strbuf_grow() loses the terminating
nul: it grows the buffer, but gives ALLOC_GROW a NULL source to avoid
it being freed. So ALLOC_GROW does not copy anything to the new
memory area.
This subtly broke the call to strbuf_getline in read_next_command()
[fast-import.c:1855], which goes
strbuf_detach(&command_buf, NULL); # command_buf is now = STRBUF_INIT
stdin_eof = strbuf_getline(&command_buf, stdin, '\n');
if (stdin_eof)
return EOF;
In strbuf_getwholeline, this did
strbuf_grow(sb, 0); # loses nul-termination
if (feof(fp))
return EOF;
strbuf_reset(sb); # this would have nul-terminated!
Valgrind found this because fast-import subsequently uses prefixcmp()
on command_buf.buf, which after the EOF exit contains only
uninitialized memory.
Arguably strbuf_getwholeline is also broken, in that it touches the
buffer before deciding whether to do any work. However, it seems more
futureproof to not let the strbuf API lose the nul-termination by its
own fault.
So make sure that strbuf_grow() puts in a nul even if it has nowhere
to copy it from. This makes strbuf_grow(sb, 0) a semantic no-op as
far as readers of the buffer are concerned.
Also remove the nul-termination added by strbuf_init, which is made
redudant.

However, the parseopt machinery does not automatically pluralize

t4014: check for empty files from git format-patch --stdout
Most kinds of failure in 'git format-patch --stdout >output' will
result in an empty 'output'. This slips past checks that only verify
absence of output, such as the '! grep ...' that are quite prevalent
in t4014.
Introduce a helper check_patch() that checks that at least From, Date
and Subject are present, thus making sure it looks vaguely like a
patch (or cover letter) email. Then insert calls to it in all tests
that do have positive checks for content.
This makes two of the tests fail. Mark them as such; they'll be

Use the pathspec pruning of traverse_trees() from unpack_trees(). Again,
the unpack_trees() machinery is primarily meant for merging two (or more)
trees, and because a merge is a full tree operation, it didn't support any
pruning with pathspec, and this codepath probably should not be enabled
while running a merge, but the caller in diff-lib.c::diff_cache() should
be able to take advantage of it.
The traverse_trees() machinery is primarily meant for merging two (or

Since d1f2d7e (Make run_diff_index() use unpack_trees(), not read_tree(),
2008-01-19), however, we use unpack_trees() to traverse_trees() callchain
to perform "diff-index", which could waste a lot of work traversing trees
outside the user-supplied pathspec, only to discard at the blob comparison
level in diff-lib.c::oneway_diff() which is way too late.

The current explanation of -e can be misread as allowing the user to say
I know 'git clean -XYZ' (substitute -XYZ with any option and/or
parameter) will remove paths A, B, and C, and I want them all removed
except for paths matching this pattern by adding '-e C' to the same
command line, i.e. 'git clean -e C -XYZ'.
But that is not what this option does. It augments the set of ignore rules
from the command line, just like the same "-e <pattern>" argument does
with the "ls-files" command (the user could probably pass "-e \!C" to tell
the command to clean everything the command would normally remove, except
for C). Also error out when both -x and -e are given with an explanation of
what -e means---it is a symptom of misunderstanding what -e does.
It also fixes small style nit in the parameter to add_exclude() call. The
current code only works because EXC_CMDL happens to be defined as 0.
