Even though 1.7.9.x series does not open the editor by default
when merging in general, it does do so in one occassion: when
merging an annotated tag. And worse yet, there is no good way
for older scripts to decline this.
Backport the support for GIT_MERGE_AUTOEDIT environment variable
from 1.7.10 track to help those stuck on 1.7.9.x maintenance
track.

"git bundle" did not record boundary commits correctly when there
are many of them.

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.

"git diff-index" and its friends at the plumbing level showed the
"diff --git" header and nothing else for a path whose cached stat
info is dirty without actual difference when asked to produce a
patch. This was a longstanding bug that we could have fixed long
time ago.

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.

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.

Match the style to more modern test scripts, namely:
- The first line of each test has prereq, title and opening sq for the
script body. This makes the test shorter while reducing the need for
backslashes.
- Be prepared for the case in which the previous test may have failed.
If a test wants to start from not having "frotz" that the previous test
may have created, write "rm -f frotz", not "rm frotz".
- Prepare the expected output inside your own test.
- The order of comparison to check the result is "diff expected actual",
so that the output will show how the output from the git you just broke
is different from what is expected.
- Write no SP between redirection '>' (or '<' for that matter) and the
filename.

fake ancestor tree by parsing the incoming patch, and another "git apply"
to apply the patch to the fake ancestor tree. Both invocation need to
be aware of the custom -p<num> setting to parse patches that were prepared

OS X's sed and grep would complain with (respectively)
sed: 1: "/^-/{p;q}": extra characters at the end of q command
grep: Regular expression too big
For sed, use an explicit ; to terminate the q command.
For grep, spell the "40 hex digits" explicitly in the regex, which
should be safe as other tests already use this and we haven't got
breakage reports on OS X about them.

print_ref_list looks up the merge_filter_ref and assumes that a valid
pointer is returned. When the object doesn't exist, it tries to
dereference a NULL pointer. This can be the case when git branch
--merged is given an argument that isn't a valid commit name.
Check whether the lookup returns a NULL pointer and die with an error
if it does. Add a test, while we're at it.

When using regexp search ('sr' parameter / $search_use_regexp variable

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:

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.

When we call convert_to_git in dry-run mode, it may still
want to look at the source buffer, because some CRLF
conversion modes depend on analyzing the source to determine
whether it is in fact convertible CRLF text.
However, the main motivation for convert_to_git's dry-run
mode is that we would decide which method to use to acquire
the blob's data (streaming versus in-core). Requiring this
source analysis creates a chicken-and-egg problem. We are
better off simply guessing that anything we can't analyze
will end up needing conversion.
This patch lets a caller specify a NULL src buffer when
using dry-run mode (and only dry-run mode). A non-zero
return value goes from "we would convert" to "we might
convert"; a zero return value remains "we would definitely
not convert".

Some callers may want to know whether convert_to_git will
actually do anything before performing the conversion
itself (e.g., to decide whether to stream or handle blobs
in-core). This patch lets callers specify the dry run mode
by passing a NULL destination buffer. The return value,
instead of indicating whether conversion happened, will
indicate whether conversion would occur.
For readability, we also include a wrapper function which
makes it more obvious we are not actually performing the
conversion.

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.

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 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.

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 comment even said that it should eventually go there. While at
it, match the calling convention and name of the function to the
strbuf_get*line family. So it now is strbuf_getwholeline_fd.

The current wording of the http.proxy documentation suggests that
http_proxy is somehow equivalent to http.proxy. However, while
http.proxy (by the means of curl's CURLOPT_PROXY option) overrides the
proxy for both HTTP and HTTPS protocols, the http_proxy environment
variable is used only for HTTP. But since the docs mention only
http_proxy, a user might expect it to apply to all HTTP-like protocols.
Avoid any such misunderstanding by explicitly mentioning https_proxy and
all_proxy as well.
Also replace linkgit:curl[1] with a literal 'curl(1)', because the
former gets translated to a dead link in the HTML pages.

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.

If any test script is run directly with Solaris 10 /usr/xpg4/bin/sh or
/bin/ksh, it fails spuriously with a message like:
t0000-basic.sh[31]: unset: bad argument count
This happens because those shells bail out when encountering a call to
"unset" with no arguments, and such unset call could take place in
'test-lib.sh'. Fix that issue, and add a proper comment to ensure we
don't regress in this respect.
