Makefile: use shell for-loop rather than Make's foreach loop during install
The install target uses a foreach loop to generate a single long shell
command line to handle installation of the built-in git commands. The
maximum length of the argument list varies by platform, and this use of
foreach quickly grows the length of the argument list. Current git can
exceed the default maximum argument list length on IRIX 6.5 of 20480
depending on the installation path.
Rather than using make's foreach loop to pre-generate the shell command
line, use a shell for-loop and allow the shell to iterate through each of
the built-in commands.

commit: more compact summary and without extra quotes
Update the report format again to save the screen real estates, while
avoiding from enclosing the one-line summary of the commit log inside
double quotes pair, which looks awkward when the message begins or ends
with a double quote. The old format looked like this:
This can be used to scan only the last few kilobytes of a reflog, as a
cheap optimization when the data you are looking for is likely to be
found near the end of it. The caller is expected to fall back to the
full scan if that is not the case.
Commit 5ef8d77a implemented color_parse_mem, a function for
parsing colors from a non-NUL-terminated string, by simply
allocating a new NUL-terminated string and calling
color_parse. This had a small but measurable speed impact on
a user format that used the advanced color parsing. E.g.,
# uses quick parsing
$ time ./git log --pretty=tformat:'%Credfoo%Creset' >/dev/null
real 0m0.673s
user 0m0.652s
sys 0m0.016s
# uses color_parse_mem
$ time ./git log --pretty=tformat:'%C(red)foo%C(reset)' >/dev/null
real 0m0.692s
user 0m0.660s
sys 0m0.032s
This patch implements color_parse_mem as the primary
function, with color_parse as a wrapper for strings. This
gives comparable timings to the first case above.

The $FIRSTLINE variable is from the user's commit and can contain
arbitrary backslash escapes that may be (mis)interpreted when given to
"echo", depending on the implementation. Use "printf" to work around the
issue.
Some SVN repositories contain git repositories within them
(hopefully accidentally checked in). Since git refuses to track
nested ".git" repositories, this can be a problem when fetching
updates from SVN.
Thanks to Morgan Christiansson for the report and testing.
The get_log() function in the Perl SVN API introduced the limit
parameter in 1.2.0. However, this got discarded in our SVN::Ra
compatibility layer when used with SVN 1.1.x. We now emulate
the limit functionality in older SVN versions by preventing the
original callback from being called if the given limit has been
reached. This emulation is less bandwidth efficient, but SVN
1.1.x is becoming rarer now.
Additionally, the --limit parameter in svn(1) uses the
aforementioned get_log() functionality change in SVN 1.2.x.
t9129 no longer depends on --limit to work and instead uses
Perl to parse out the commit message.
By default git-svn stores timestamps of fetched commits in
Subversion's UTC format. Passing --localtime to fetch will convert
them to the timezone of the server on which git-svn is run.
This makes the timestamps of a resulting "git log" agree with what
"svn log" shows for the same repository.

Since broken SVN clients can commit svn:special files without
the magic "link " prefix, this can affect delta application
when we update the broken svn:special file. So now we fall
back and retry the delta application on symlinks if having
a "link " prefix fails.
Our behavior differs from svn(1) (v1.5.1) slightly:
When a svn:special file is created w/o a "link " prefix, svn
will create a regular file (mode 100644 to git) with the
contents of the blob as-is.
Our behavior is to continue creating the symlink (mode 120000
to git) with the contents of the blob as-is. While this
differs from current svn(1) behavior, this is easier and more
efficient to implement (and the correctness of the svn(1) is
debatable, since it's a workaround for a bug in the first
place).
More information on this SVN bug is described here:
http://subversion.tigris.org/issues/show_bug.cgi?id=2692
git-svn: handle empty files marked as symlinks in SVN
Broken SVN clients generate empty files with the svn:special set
to '*'. This attempts to denote a symlink pointing to a file
with an empty path (""), which cannot be generated on a POSIX
system.
Thus, we mimic the behavior of svn(1) and create a zero-byte
file in our tree.
The "matching refs" semantics works only on matching branches these days.
Instead of using "heads" which traditionally has been used more or less
interchangeably with "refs", say "branch" explicitly here.

lstat_cache(): introduce has_dirs_only_path() function
The create_directories() function in entry.c currently calls stat()
or lstat() for each path component of the pathname 'path' each and every
time. For the 'git checkout' command, this function is called on each
file for which we must do an update (ce->ce_flags & CE_UPDATE), so we get
lots and lots of calls.
To fix this, we make a new wrapper to the lstat_cache() function, and
call the wrapper function instead of the calls to the stat() or the
lstat() functions. Since the paths given to the create_directories()
function, is sorted alphabetically, the new wrapper would be very
cache effective in this situation.
To support it we must update the lstat_cache() function to be able to
say that "please test the complete length of 'name'", and also to give
it the length of a prefix, where the cache should use the stat()
function instead of the lstat() function to test each path component.

So we update the lstat_cache() function to handle this new fact,
introduce a new wrapper function, and the result is that we save lots
of lstat() calls for a removed directory which previously contained
lots of files, when we call this new wrapper of lstat_cache() instead
of the old one.
We do similar changes inside the unlink_entry() function, since if we
can already say that the leading directory component of a pathname
does not exist, it is not necessary to try to remove a pathname below
it!

lstat_cache(): more cache effective symlink/directory detection
Make the cache functionality more effective. Previously when A/B/C/D
was in the cache and A/B/C/E/file.c was called for, there was no match
at all from the cache. Now we use the fact that the paths "A", "A/B"
and "A/B/C" are already tested, and we only need to do an lstat() call
on "A/B/C/E".
We only cache/store the last path regardless of its type. Since the
cache functionality is always used with alphabetically sorted names
(at least it seems so for me), there is no need to store both the last
symlink-leading path and the last real-directory path. Note that if
the cache is not called with (mostly) alphabetically sorted names,
neither the old, nor this new one, would be very effective.
Previously, when symlink A/B/C/S was cached/stored in the symlink-
leading path, and A/B/C/file.c was called for, it was not easy to use
the fact that we already knew that the paths "A", "A/B" and "A/B/C"
are real directories.
Avoid copying the first path components of the name 2 zillion times
when we test new path components. Since we always cache/store the
last path, we can copy each component as we test those directly into
the cache. Previously we ended up doing a memcpy() for the full
path/name right before each lstat() call, and when updating the cache
for each time we have tested a new path component.
We also use less memory, that is, PATH_MAX bytes less memory on the
stack and PATH_MAX bytes less memory on the heap.

t7700: demonstrate misbehavior of 'repack -a' when local packs exist
The ability to "...fatten [the] local repository by packing everything that
is needed by the local ref into a single new pack, including things that are
borrowed from alternates"[1] is supposed to be provided by the '-a' or '-A'
options to repack when '-l' is not used, but there is a flaw. For each
pack in the local repository without a .keep file, repack supplies a
--unpacked=<pack> argument to pack-objects.
The --unpacked option to pack-objects, with or without an argument, causes
pack-objects to ignore any object which is packed in a pack not mentioned
in an argument to --unpacked=. So, if there are local packs, and
'repack -a' is called, then any objects which reside in packs accessible
through alternates will _not_ be packed. If there are no local packs, then
no --unpacked argument will be supplied, and repack will behave as expected.

There are three flags involved (-w -b and --ignore-space-at-eol) which

color: make it easier for non-config to parse color specs
We have very featureful color-parsing routines which are
used for color.diff.* and other options. Let's make it
easier to use those routines from other parts of the code.
This patch adds a color_parse_mem() helper function which
takes a length-bounded string instead of a NUL-terminated
one. While the helper is only a few lines long, it is nice
to abstract this out so that:
- callers don't forget to free() the temporary buffer
- right now, it is implemented in terms of color_parse().
But it would be more efficient to reverse this and
implement color_parse in terms of color_parse_mem.
This also changes the error string for an invalid color not
to mention the word "config", since it is not always
appropriate (and when it is, the context is obvious since
the offending config variable is given).
Finally, while we are in the area, we clean up the parameter
names in the declaration of color_parse; the var and value
parameters were reversed from the actual implementation.

output by the offsets (which agreed since the original text had the

This code was ugly, for a number of reasons:
- it was impossible to introduce 0-character word boundaries,
- we had to print everything word by word, and
- the code needed extra special handling of newlines in the removed part.
Fix all of these issues by processing the text such that
- we build word lists, separated by newlines,
- we remember the original offsets for every word, and
- after calling libxdiff on the wordlists, we parse the hunk headers, and
find the corresponding offsets, and then
- we print the removed/added parts in one go.
The pre and post samples in the test were provided by Santi Béjar.
Note that there is some strange special handling of hunk headers where
one line range is 0 due to POSIX: in this case, the start is one too
low. In other words a hunk header '@@ -1,0 +2 @@' actually means that
the line must be added after the _second_ line of the pre text, _not_
the first.

t3501: check that commits are actually done
The basic idea of t3501 is to check whether revert
and cherry-pick works on renamed files.
But as there is no pure cherry-pick/revert test, it is
good to also check if commits are actually done in that
scenario.

bash-completion: Add comments to remind about required arguments
Add a few simple comments above commands that take arguments. These
comments are meant to remind developers of potential problems that
can occur when the script is sourced on systems with "set -u." Any
function which requires arguments really ought to be called with
explicit arguments given.
Also adds a #!bash to the top of bash completions so that editing
software can always identify that the file is of sh type.
