apply, entry: speak of submodules instead of subprojects
There are only four (with some generous rounding) instances in the
current source code where we speak of "subproject" instead of
"submodule". They are as follows:
* one error message in git-apply and two in entry.c
* the patch format for submodule changes
The latter was introduced in 0478675 (Expose subprojects as special
files to "git diff" machinery, 2007-04-15), apparently before the
terminology was settled. We can of course not change the patch
format.
Let's at least change the error messages to consistently call them
"submodule".

Commit adbc0b6b ("cygwin: Use native Win32 API for stat", 30-09-2008)
added a Win32 specific implementation of the stat functions. In order
to handle absolute paths, cygwin mount points and symbolic links, this
implementation may fall back on the standard cygwin l/stat() functions.
Also, the choice of cygwin or Win32 functions is made lazily (by the
first call(s) to l/stat) based on the state of some config variables.
do_one_ref(): save and restore value of current_ref
If do_one_ref() is called recursively, then the inner call should not
permanently overwrite the value stored in current_ref by the outer
call. Aside from the tiny optimization loss, peel_ref() expects the
value of current_ref not to change across a call to peel_entry(). But
in the presence of replace references that assumption could be
violated by a recursive call to do_one_ref:
The inner call to do_one_ref() was unconditionally setting current_ref
to NULL when it was done, causing peel_ref() to perform an invalid
memory access.
So change do_one_ref() to save the old value of current_ref before
overwriting it, and restore the old value afterward rather than
setting it to NULL.

blame-options.txt: place each -L option variation on its own line
Standard practice in Git documentation is for each variation of an

OPTIONS table. The -L option does not follow suit. It cuddles
"-L <start>,<end>" and "-L :<regex>", separated by a comma. This is

is typeset the same as the comma in "<start>,<end>". Fix this by placing

"blame -L X,-N" is documented as blaming "N lines ending at X". In

diff: allow lowercase letter to specify what change class to exclude
In order to express "we do not care about deletions", we had to say
"--diff-filter=ACMRTXUB", giving all the possible change class
except for the one we do not want, "D".
This is cumbersome. As all the change classes are in uppercase,
allow their lowercase counterpart to selectively exclude the class
from the output. When such a negated change class is in the input,
start the filter option with the full bits set.
This would allow us to express the old "show-diff -q" with
"git diff-files --diff-filter=d".
diff: reject unknown change class given to --diff-filter
We used to accept "git diff --diff-filter=Q" (note that there is no
such change class 'Q') silently and showed no output (because there
is no such change class 'Q').
Instead of running strchr() on the list of status characters over
and over again, parse the --diff-filter option into bitfields and
use the bits to see if the change to the filepair matches the status
requested.
diffcore_apply_filter() checks if a filepair matches the filter
given with the "--diff-filter" option for each input filepairs with
a fairly complex expression in two places.
diff: pass the whole diff_options to diffcore_apply_filter()
The --diff-filter=<arg> option given by the user is kept as a
string, and passed to the underlying diffcore_apply_filter()
function as a string for each resulting path we run number of
strchr() to see if each class of change among ACDMRTXUB is meant to
be given.
Change the function signature to pass the whole diff_options, so
that we can pre-parse this string in the next patch.
Not having an open FD in the 0--2 range can lead to strange results,
for example, a subsequent open() may return 2 (stderr) and then a
die() would clobber this file.
git-daemon and git-shell already guarded against this, but apparently
users also manage to trip over it in other git commands. So we call
sanitize_stdfds() during main git startup.
Since these FDs are inherited, this covers all use of 'git foo ...',
and all internal C commands when called directly. It does not fix
shell/perl commands called directly.

git-multimail: an improved replacement for post-receive-email
Add git-multimail, a tool for generating notification emails for
pushes to a Git repository. It is largely plug-in compatible with
post-receive-email, and is proposed to eventually replace that script.
The advantages of git-multimail relative to post-receive-email are
described in README.migrate-from-post-receive-email.
git-multimail is organized in a directory contrib/hooks/multimail.
The directory contains:
* git_multimail.py -- a Python module that can generate notification
emails for pushes to a Git repository. The file can be used
directly as a post-receive script (configured via git config
settings), or it can be imported as a Python module and configured
via arbitrary Python code.
* README -- user-level documentation for configuring and using
git-multimail.
* post-receive -- an example of building a post-receive script that
imports git_multimail.py as a Python module, with an example of how
to change the email templates.
* README.migrate-from-post-receive-email -- documentation targeted at
current users of post-receive-email, explaining the differences and
how to migrate a post-receive-email configuration to git-multimail.
* migrate-mailhook-config -- a script that can migrate a user's
post-receive-email configuration options to the equivalent
git-multimail options.
* README.Git -- a short explanation of the relationship between
git-multimail and the rest of the Git project, plus the exact date
and revision when this version was taken from the upstream project.
All but the last file are taken verbatim from the upstream
git-multimail project.
git-multimail is originally derived from post-receive-email and also
incorporates suggestions from the mailing list as well as patches by
the people listed below.

:(glob)path differs from plain pathspec that it uses wildmatch with
WM_PATHNAME while the other uses fnmatch without FNM_PATHNAME. The
difference lies in how '*' (and '**') is processed.
With the introduction of :(glob) and :(literal) and their global
options --[no]glob-pathspecs, the user can:
- make everything literal by default via --noglob-pathspecs
--literal-pathspecs cannot be used for this purpose as it
disables _all_ pathspec magic.
- individually turn on globbing with :(glob)
- make everything globbing by default via --glob-pathspecs
- individually turn off globbing with :(literal)
The implication behind this is, there is no way to gain the default
matching behavior (i.e. fnmatch without FNM_PATHNAME). You either get
new globbing or literal. The old fnmatch behavior is considered
deprecated and discouraged to use.

parse_pathspec: preserve prefix length via PATHSPEC_PREFIX_ORIGIN
The prefix length is passed from one command to another via the new
magic 'prefix'. The magic is for parse_pathspec's internal use only,
not visible to parse_pathspec's callers.
Prefix length is not preserved across commands when --literal-pathspecs
is specified (no magic is allowed, including 'prefix'). That's OK
because we know all paths are literal. No magic, no special treatment
regarding prefix. (This may be no longer true if we make :(glob)
default)
Other options to preserve the prefix include saving it to env variable
or quoting. Env var way (at least _one_ env var) is not suitable
because the prefix is not the same for all pathspecs. Pathspecs
starting with "../" will eat into the prefix part.
We could also preserve 'prefix' across commands by quoting the prefix
part, then dequoting on receiving. But it may not be 100% accurate, we
may dequote longer than the original prefix part, for example. That
may be good or not, but it's not the purpose.

subcommand can no longer calculate the prefix itself.

parse_pathspec: add special flag for max_depth feature
match_pathspec_depth() and tree_entry_interesting() check max_depth
field in order to support "git grep --max-depth". The feature
activation is tied to "recursive" field, which led to some unwanted
activation, e.g. 5c8eeb8 (diff-index: enable recursive pathspec
matching in unpack_trees - 2012-01-15).
This patch decouples the activation from "recursive" field, puts it in
"magic" field instead. This makes sure that only "git grep" can
activate this feature. And because parse_pathspec knows when the
feature is not used, it does not need to sort pathspec (required for
max_depth to work correctly). A small win for non-grep cases.
Even though a new magic flag is introduced, no magic syntax is. The
magic can be only enabled by parse_pathspec() caller. We might someday
want to support ":(maxdepth:10)src." It all depends on actual use
cases.
max_depth feature cannot be enabled via init_pathspec() anymore. But
that's ok because init_pathspec() is on its way to /dev/null.

"paths" can only carry bare strings, which loses information from
command line arguments such as pathspec magic or the prefix part's
length for each argument.
parse_pathspec() is introduced to combine the two calls into one. The
plan is gradually replace all get_pathspec() and init_pathspec() with
parse_pathspec(). get_pathspec() now becomes a thin wrapper of
parse_pathspec().
parse_pathspec() allows the caller to reject the pathspec magics that
it does not support. When a new pathspec magic is introduced, we can
enable it per command after making sure that all underlying code has no
problem with the new magic.
"flags" parameter is currently unused. But it would allow callers to
pass certain instructions to parse_pathspec, for example forcing
literal pathspec when no magic is used.
With the introduction of parse_pathspec, there are now two functions
that can initialize struct pathspec: init_pathspec and
parse_pathspec. Any semantic changes in struct pathspec must be
reflected in both functions. init_pathspec() will be phased out in
favor of parse_pathspec().
