52b8ea934e gitk: Fix possible infinite loop and display corruption
This fixes an issue reported by Johannes Sixt on the git mailing list:

> This recipe sends gitk into an endless loop. In git.git do:
>
> cd t
> # remove chmod a+x A near the end of the file
> sed -i 's/chmod/: chmod/' t3400-rebase.sh
> sh t3400-rebase.sh --debug
> cd trash\ directory.t3400-rebase/
> gitk master modechange modechange@{1}
>
>
> I briefly see the history chart, but the dot that should be modechange@{1}
> is missing. One automatically selected commit is shown in the diff section
> below. But then the commit list is cleared and gitk goes into an infinite
> loop.
>
> Things work alright if either modechange@{1} is dropped, or the 'chmod'
> line is left unchanged, which is a bit strange.
>
> This is with git version 1.6.1.2.390.gba743

There were actually two problems.  This recipe created a situation where
git log would output a child commit after its parent.  This meant that
we called fix_reversal which called splitvarc, which should call modify_arc
to note the fact that it has modified the arc that it has just split.  It
wasn't, which meant that displayorder and other variables got into an
inconsistent state (a commit appearing twice in displayorder).

This then meant that the targetrow/targetid logic in drawvisible thought
it need to redraw each time.  That, together with the fact that drawvisible
called drawcommits which called drawvisible if a redraw was needed, led
to the infinite loop.

In fact drawvisible is now the only caller of drawcommits.  Thus, the
start and end row arguments to drawcommits always encompass the whole
visible area, so drawcommits doesn't need to call drawvisible to redraw;
it just needs to clear the screen and draw what it's been asked to.

This fixes these two problems by adding a call to modify_arc in
splitvarc and by taking out the call to drawvisible in drawcommits.
It also removes an unrelated left-over debugging puts in external_blame.

736e619a1b git-svn - return original format_svn_date semantics
When %z was removed from the strftime call and subsituted with a
local gmt offset calculation, time() was no longer the default for
all time functions as it was with the previous localtime(shift).
This is now corrected so that format_svn_time behaves as it used to.

48679e5c2d git-svn: disable broken symlink workaround by default
Even though this will break things for some extremely rare repositories
used by broken Windows clients, it's probably not worth enabling this by
default as it has negatively affected many more users than it has helped
from what we've seen so far.

The extremely rare repositories that have broken symlinks in them will be
silently corrupted in import; but users can still reenable this option and
restart the import.

cce074a276 bisect: fix another instance of eval'ed string
When there is nothing to be skipped, the output from
rev-list --bisect-vars was eval'ed without first being
strung together with &&; this is probably not a problem
as it is much less likely to be a bad input than the list
handcrafted by the filter_skip function, but it still is
a good discipline.

1b249ffe8d bisect: fix quoting TRIED revs when "bad" commit is also "skip"ped
When the "bad" commit was also "skip"ped and when more than one
commit was skipped, the "filter_skipped" function would have
printed something like:

    bisect_rev=<hash1>|<hash2>

(where <hash1> and <hash2> are hexadecimal sha1 hashes)

and this would have been evaled later as piping "bisect_rev=<hash1>"
into "<hash2>", which would have failed.

So this patch makes the "filter_skipped" function properly quote
what it outputs, so that it will print something like:

bisect_rev='<hash1>|<hash2>'

which will be properly evaled later.  The caller was not stopping
properly because the scriptlet this function returned to be evaled
was not strung together with && and because of this, an error in
an earlier part of the output was simply ignored.

A test case is added to the test suite.

And while at it, we also initialize the VARS, FOUND and TRIED
variables, so that we protect ourselves from environment variables
the user may have with these names.

2d56a13643 git-am: make --abort less dangerous
When you are in the middle of "git rebase", "git am --abort" by mistake
would have referred to nonexistent ORIG_HEAD and barfed, or worse yet, used

OS X's GNU grep does not support -P/--perl-regexp.

We use a basic RE instead, and simplify the pattern slightly by
replacing '+' with '*' so it can be more easily expressed using a basic

the successful PUT/MOVE operations, remains the same.  Also, a-z instead
of a-f was an obvious mistake in the original RE. Here are samples of

6e180cdcec Make sure objects/pack exists before creating a new pack
In a repository created with git older than f49fb35 (git-init-db: create
"pack" subdirectory under objects, 2005-06-27), objects/pack/ directory is
not created upon initialization.  It was Ok because subdirectories are
created as needed inside directories init-db creates, and back then,
packfiles were recent invention.

After the said commit, new codepaths started relying on the presense of
objects/pack/ directory in the repository.  This was exacerbated with
8b4eb6b (Do not perform cross-directory renames when creating packs,
2008-09-22) that moved the location temporary pack files are created from
objects/ directory to objects/pack/ directory, because moving temporary to
the final location was done carefully with lazy leading directory creation.

Many packfile related operations in such an old repository can fail
mysteriously because of this.

This commit introduces two helper functions to make things work better.

 - odb_mkstemp() is a specialized version of mkstemp() to refactor the
   code and teach it to create leading directories as needed;

 - odb_pack_keep() refactors the code to create a ".keep" file while
   create leading directories as needed.

69707d616f Allow HTTP tests to run on Darwin
This patch allows the HTTP tests to run on OS X 10.5. It is not
sufficient to be able to pass in LIB_HTTPD_PATH and
LIB_HTTPD_MODULE_PATH alone, as the apache.conf also needs a couple
tweaks.

These changes are put into an <IfDefine> to keep them Darwin specific,
but this means lib-httpd.sh needs to be modified to pass -DDarwin to
apache when running on Darwin. As long as we're making this change to
lib-httpd.sh, we may as well set LIB_HTTPD_PATH and
LIB_HTTPD_MODULE_PATH to appropriate default values for the platform.

Note that we now pass HTTPD_PARA to apache at shutdown as well.
Otherwise apache will emit a harmless, but noisy warning that LogFormat
is an unknown directive.

README suggested to look at "Documentation/gittutorial.txt" for the

This was not consistent because the tutorial can also be available with
"man gittutorial" once git is installed, and the documentation for each
command can be available at "Documentation/git-commandname.txt" before
installing git.

This patch tries to make the description more consistent.  It also fixes

get things in the raw format. Sure, you get them with --pretty=raw, but it
felt a bit sad that you couldn't just ask for the date in raw format.

So here's a throw-away patch (meaning: I won't be re-sending it, because I
really don't think it's a big deal) to add "--date=raw". It just prints
out the internal raw git format - seconds since epoch plus timezone (put
another way: 'date +"%s %z"' format)

7d233dea5f gitweb: Hyperlink multiple git hashes on the same commit message line
The current implementation only hyperlinks the first hash on
a given line of the commit message.  It seems sensible to
highlight all of them if there are multiple, and it seems
plausible that there would be multiple even with a tidy line
length limit, because they can be abbreviated as short as 8
characters.

Benchmark:

I wanted to make sure that using the 'e' switch to the Perl regex
wasn't going to kill performance, since this is called once per commit
message line displayed.

In all three A/B scenarios I tried, the A and B yielded the same
results within 2%, where A is the version of code before this patch
and B is the version after.

1: View a commit message containing the last 1000 commit hashes
2: View a commit message containing 1000 lines of 40 dots to avoid
   hyperlinking at the same message length
3: View a short merge commit message with a few lines of text and
   no hashes

All were run in CGI mode on my sub-production hardware on a recent
clone of git.git.  Numbers are the average of 10 reqests per second
with the first request discarded, since I expect this change to affect
primarily CPU usage.  Measured with ApacheBench.

Note that the web page rendered was the same; while the new code
supports multiple hashes per line, there was at most one per line.

The primary purpose of scenarios 2 and 3 were to verify that the
addition of 1000 commit messages had an impact on how much of the time
was spent rendering commit messages.  They were all within 2% of 0.80
requests per second (much faster).

So I think the patch has no noticeable effect on performance.

024aa7d8d5 system_path(): simplify using strip_path_suffix(), and add suffix "git"
At least for the author of this patch, the logic in system_path() was
too hard to understand.  Using the function strip_path_suffix() documents
the idea of the code better.

The real change is to add the suffix "git", so that a runtime prefix will
be computed correctly even when the executable was called in /git/ as is
the case in msysGit (Windows insists to search the current directory
before the PATH when looking for an executable).

4fcc86b07d Introduce the function strip_path_suffix()
The function strip_path_suffix() will try to strip a given suffix from
a given path.  The suffix must start at a directory boundary (i.e. "core"
is not a path suffix of "libexec/git-core", but "git-core" is).

Arbitrary runs of directory separators ("slashes") are assumed identical.

Example:

	strip_path_suffix("C:\\msysgit/\\libexec\\git-core",
		"libexec///git-core", &prefix)

will set prefix to "C:\\msysgit" and return 0.
