'rerere gc' prunes resolutions of conflicted merges that occurred long
time ago, and when doing so it takes the creation time of the
conflicted automerge results into account. This can cause the loss of
frequently used conflict resolutions (e.g. long-living topic branches
are merged into a regularly rebuilt integration branch (think of git's
pu)) when they become old enough to exceed 'rerere gc's threshold.
To prevent the loss of valuable merge resolutions 'rerere' will (1)
update the timestamp of the recorded conflict resolution (i.e.
'postimage') each time when encountering and resolving the same merge
conflict, and (2) take this timestamp, i.e. the time of the last usage
into account when gc'ing.

The original declaration was int, which seems to cause trouble on my
machine. It causes spurious "filesystem boundary" errors when running
the testsuite. The cause seems to be
$ stat -c%d .
2147549952
which is too large for a 32-bit int type.
Using the correct type, dev_t, solves the issue. (Because I'm
paranoid and forgetful, I checked -- yes, Unix v7 had dev_t.)
Other uses of st_dev seem to be reasonably safe. fill_stat_cache_info
truncates it to an 'unsigned int', but that value seems to be used only
to validate the cache, and only if USE_STDEV is defined.

Currently, the graph code is hardcoded to use ANSI color escapes for
coloring the column characters in the generated graphs. This patch
allows a custom scheme of colors to be set at runtime, allowing
different types of color escapes to be used.
A new function - graph_set_column_colors() - is added to the graph.h API,
which allows a custom column_colors array (and column_colors_max value)
to replace the builtin ANSI array (and _max value). The new function -
if used - must be called before graph_init() is called.

All of the interface messages in Git core are currently hardcoded in
English. Change that by optionally enabling translation of the core C,
Shell and Perl programs via GNU or SunOS gettext. If you set the
appropriate LC_* variables Git will speak your language, provided that
someone has submitted a translation.
If gettext isn't available, or if Git is compiled with
NO_GETTEXT=YesPlease, then Git fall back on its previous behavior of
only speaking English. When using ./configure the autoconf script will
auto-detect if the gettext libraries are installed and act
appropriately.
With NO_GETTEXT=YesPlease gettext support will be #defined away for C
programs. For Shell and Perl programs we rely on the git message
catalog not being available. That's a reasonable assumption since then
the message catalog won't be installed on the system during make
install.
The gettext wrappers that are provided in the patch are only the bare
minimum required to begin translation work. In particular I haven't
added wrappers for the gettext functions that enable plural support,
or those that provide message context (msgctxt).
Those can be added later. The intent is to start with a small subset
and see what we need later, not to start with something that's
unnecessarily large right away.
Implementation and usage notes:
* General:
Gettext .mo files will be installed and looked for in the standard
$(prefix)/share/locale path. GIT_TEXTDOMAINDIR can also be set to
override that, but that's only intended to be used to test Git
itself.
* Perl:
Perl code that wants to be localized should use the new Git::I18n
module. It imports a __ function into the caller's package by
default.
Instead of using the high level Locale::TextDomain interface I've
opted to use the low-level (equivalent to the C interface)
Locale::Messages module, which Locale::TextDomain itself uses.
Locale::TextDomain does a lot of redundant work we don't need, and
some of it would potentially introduce bugs. It tries to set the
$TEXTDOMAIN based on package of the caller, and has its own
hardcoded paths where it'll search for messages.
I found it easier just to completely avoid it rather than try to
circumvent its behavior. In any case, this is an issue wholly
internal Git::I18N. Its guts can be changed later if that's deemed
necessary.
See <AANLkTilYD_NyIZMyj9dHtVk-ylVBfvyxpCC7982LWnVd@mail.gmail.com>
for a further elaboration on this topic.
* Shell:
Shell code that's to be localized should use the new git-sh-i18n
library. It's just a wrapper for the system's gettext.sh.
If gettext.sh isn't available we'll fall back gettext(1) if it's
available. The latter is available without the former on Solaris,
which has its own non-GNU gettext implementation. We also need to
emulate eval_gettext() there.
If neither are present we'll use a dumb printf(1) fall-through
wrapper.
I originally tried to detect if the system supported `echo -n' but
I found this to be a waste of time. My benchmarks on Linux, Solaris
and FreeBSD reveal that printf(1) is fast enough, especially since
we aren't calling gettext() from within any tight loops, and
unlikely to ever do so.
This series has been tested by me on Ubuntu 10.04, Debian testing,
FreeBSD 8.1 and SunOS 5.10, and by others on Mac OS X 10.6.3 (with
Xcode 3.2.2) and openSUSE Factory (11.3, milestone 7).
SunOS has its own non-GNU gettext implementation which this patch
supports, although that may change in the future if it turns out that
we need some GNU libintl features that SunOS doesn't provide.
This patch is based on work by Jeff Epler <jepler@unpythonic.net> who
did the initial Makefile / C work, and a lot of comments from the Git
mailing list, including Jonathan Nieder, Jakub Narebski, Johannes
Sixt, Peter Krefting, Junio C Hamano, Thomas Rast and others.

When older versions of fast-export came across a directory changing to a
symlink (or regular file), it would output the changes in the form
M 120000 :239821 dir-changing-to-symlink
D dir-changing-to-symlink/filename1
When fast-import sees the first line, it deletes the directory named
dir-changing-to-symlink (and any files below it) and creates a symlink in
its place. When fast-import came across the second line, it was previously
trying to remove the file and relevant leading directories in
tree_content_remove(), and as a side effect it would delete the symlink
that was just created. This resulted in the symlink silently missing from
the resulting repository.
To improve robustness, we ignore file deletions underneath directory names
that correspond to non-directories. This can also be viewed as a minor
optimization: since there cannot be a file and a directory with the same
name in the same directory, the file clearly can't exist so nothing needs
to be done to delete it.

The fast-import stream format requires incremental changes which take place
immediately, meaning that for D->F conversions all files below the relevant
directory must be deleted before the resulting file of the same name is
created. Reversing the order can result in fast-import silently deleting
the file right after creating it, resulting in the file missing from the
resulting repository.
We correct this by first sorting the diff_queue_struct in depth-first
order.

The rename logic in process_renames() handles renames and merging of file
contents and then marks files as processed. However, there may be higher
stage entries left in the index for other reasons (e.g., due to D/F
conflicts). By checking for such cases and marking the entry as not
processed, it allows process_entry() later to look at it and handle those
higher stages.

The D/F conflicts that can be automatically resolved (file or directory
unmodified on one side of history), have the nice property that
process_entry() can correctly handle all subpaths of the D/F conflict. In
the case of D->F conversions, it will correctly delete all non-conflicting
files below the relevant directory and the directory itself (note that both
untracked and conflicting files below the directory will prevent its
removal). So if we handle D/F conflicts after all other conflicts, they
become fairly simple to handle -- we just need to check for whether or not
a path (file/directory) is in the way of creating the new content. We do
this by having process_entry() defer handling such entries to a subsequent
process_df_entry() step.

"read-tree -m A B" is to take the index (and the working tree)

This implements a simple merge strategy for submodule hashes. We check
whether one side of the merge candidates is already contained in the
other and then merge automatically.
If both sides contain changes we search for a merge in the submodule.
In case a single one exists we check that out and suggest it as the
merge resolution. A list of candidates is returned when we find multiple
merges that contain both sides of the changes.
This is useful for a workflow in which the developers can publish topic
branches in submodules and a separate maintainer merges them. In case
the developers always wait until their branch gets merged before tracking
them in the superproject all merges of branches that contain submodule
changes will be resolved automatically. If developers choose to track
their feature branch the maintainer might get a conflict but git will
search the submodule for a merge and suggest it/them as a resolution.

When you have for example a bare repository stored on NFS, and that you

is a symlink to a different device. Hence when the reflogs are renamed,
all must happen below logs/refs or one gets cross device rename errors
like:

error: unable to move logfile logs/refs/heads/master to tmp-renamed-log: Invalid cross-device link
