When git spawns a remote helper program (like git-remote-http),
the last thing we do before closing the pipe to the child
process is to send a blank line, telling the helper that we
are done issuing commands. However, the helper may already
have exited, in which case the parent git process will
receive SIGPIPE and die.
In particular, this can happen with the remote-curl helper
when it encounters errors during a push. The helper reports
individual errors for each ref back to git-push, and then
exits with a non-zero exit code. Depending on the exact
timing of the write, the parent process may or may not
receive SIGPIPE.
This causes intermittent test failure in t5541.8, and is a
side effect of 5238cbf (remote-curl: Fix push status report
when all branches fail). Before that commit, remote-curl
would not send the final blank line to indicate that the
list of status lines was complete; it would just exit,
closing the pipe. The parent git-push would notice the
closed pipe while reading the status report and exit
immediately itself, propagating the failing exit code. But
post-5238cbf, remote-curl completes the status list before
exiting, git-push actually runs to completion, and then it
tries to cleanly disconnect the helper, leading to the
SIGPIPE race above.
This patch drops all error-checking when sending the final
"we are about to hang up" blank line to helpers. There is
nothing useful for the parent process to do about errors at
that point anyway, and certainly failing to send our "we are
done with commands" line to a helper that has already exited
is not a problem.

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.

The --ff-only option was not described next to --ff and --no-ff options in
"git merge" documentation, even though these three are logically together,
describing how to choose one of three possibilities.
Also the description for '--ff' and '--no-ff' discussed what '--ff' means,
and mentioned '--no-ff' as if it were a side-note to '--ff'.
Make them into three top-level entries and list them together. This way,
it would be more clear that the user can choose one from these three.

If a filter is not defined or if it fails, git should behave as if the
filter is a no-op passthru.
However, if the filter exits before reading all the content, depending on
the timing, git could be killed with SIGPIPE when it tries to write to the
pipe connected to the filter.
Ignore SIGPIPE while processing the filter to give us a chance to check
the return value from a failed write, in order to detect and act on this
mode of failure in a more controlled way.

If the argument for `__git_ps1` begins with a dash, `printf` tries to
interpret it as an option which results in an error message.
The problem is solved by adding '--' before the argument to tell
`printf` to not interpret the following argument as an option.
Adding '--' directly to the argument does not help because the argument
is enclosed by double quotes.

The current configure script uses -lintl if gettext is not found in the C
library, but does so before checking if there is libintl.h available in
the first place, in which case we would later define NO_GETTEXT.
Instead, check for the existence of libintl.h first. Only when libintl.h
exists and libintl is not in libc, ask for -lintl.

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.

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'".

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.

When commit 3ed74e6 (diff --stat: ensure at least one '-' for deletions,
and one '+' for additions, 2006-09-28) improved the output for files with
tiny modifications, we accidentally broke the logic to ensure that two
equal sized changes are shown with the bars of the same length, even when
rounding errors exist.
Compute the length of the graph bars, using the same "non-zero changes is
shown with at least one column" scaling logic, but by scaling the sum of
additions and deletions to come up with the total length of the bar (this
ensures that two equal sized changes result in bars of the same length),
and then scaling the smaller of the additions or deletions. The other side
is computed as the difference between the two.
This makes the apportioning between additions and deletions less accurate
due to rounding errors, but it is much less noticeable than two files with
the same amount of change showing bars of different length.

The effect of this buglet can be observed by opening a wide terminal and

"git help --all" uses the full terminal width. Run the check before we

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.
