fast-import: zero all of 'struct tag' to silence valgrind

When running t9300, valgrind (correctly) complains about an
uninitialized value in write_crash_report:

Fix this by zeroing all of the 'struct tag'. We would only need to
zero out the 'sha1' field, but this way seems more future-proof.

http.proxy: also mention https_proxy and all_proxyClemens Buchacher Sun, 4 Mar 2012 16:50:43 +0000 (17:50 +0100)

http.proxy: also mention https_proxy and all_proxy

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.

t0300: work around bug in dash 0.5.6Michael J Gruber Sat, 3 Mar 2012 00:37:35 +0000 (19:37 -0500)

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.

This happens because those shells bail out when encountering a call to

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.

grep -P: Fix matching ^ and $Michał Kiedrowicz Sat, 25 Feb 2012 09:24:28 +0000 (10:24 +0100)

grep -P: Fix matching ^ and $

When "git grep" is run with -P/--perl-regexp, it doesn't match ^ and $ at
the beginning/end of the line. This is because PCRE normally matches ^
and $ at the beginning/end of the whole text, not for each line, and "git
grep" passes a large chunk of text (possibly containing many lines) to
pcre_exec() and then splits the text into lines.

This makes "git grep -P" behave differently from "git grep -E" and also
from "grep -P" and "pcregrep":

$ cat file
a
b
$ git grep --no-index -P '^ ' file
$ git grep --no-index -E '^ ' file
file: b
$ grep -c -P '^ ' file
b
$ pcregrep -c '^ ' file

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().

copy, delete).

do not stream large files to pack when filters are... Jeff King Fri, 24 Feb 2012 22:10:17 +0000 (17:10 -0500)

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.

teach dry-run convert_to_git not to require a src bufferJeff King Fri, 24 Feb 2012 22:05:03 +0000 (17:05 -0500)

teach dry-run convert_to_git not to require a src buffer

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".

teach convert_to_git a "dry run" mode

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.

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.

disconnect from remote helpers more gentlyJeff King Thu, 23 Feb 2012 10:04:34 +0000 (05:04 -0500)

disconnect from remote helpers more gently

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.

bundle: use a strbuf to scan the log for boundary commitsThomas Rast Wed, 22 Feb 2012 19:34:23 +0000 (20:34 +0100)

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.

Ignore SIGPIPE when running a filter driver

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.

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.

gitweb: Fix "heads" view when there is no current branchJakub Narebski Wed, 15 Feb 2012 15:36:41 +0000 (16:36 +0100)

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.

diff --stat: show bars of same length for paths with same amount of changes

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.
