from "foo" to _("foo"), and didn't need any TRANSLATORS comments.

The Q_ function translates a string representing some pharse with an
alternative plural form and uses the 'count' argument to choose which
form to return. Use of Q_ solves the "%d noun(s)" problem in a way
that is portable to languages outside the Germanic and Romance
families.
In English, the semantics of Q_(sing, plur, count) are roughly
equivalent to
count == 1 ? _(sing) : _(plur)
while in other languages there can be more variants (count == 0; more
random-looking rules based on the historical pronunciation of the
number). Behind the scenes, the singular form is used to look up a
family of translations and the plural form is ignored unless no
translation is available.
Define such a Q_ in gettext.h with the English semantics so C code can
start using it to mark phrases with a count for translation.
The name "Q_" is taken from subversion and stands for "quantity".
Many projects just use ngettext directly without a wrapper analogous
to _; we should not do so because git's gettext.h is meant not to
conflict with system headers that might include libintl.h.

submodule update: Don't fetch when the submodule commit is already present
If the commit to be checked out on "git submodule update" has already been
fetched in the submodule there is no need to run "git fetch" again. Since
"git fetch" recently learned recursion (and the new on-demand mode to
fetch commits recorded in the superproject is enabled by default) this
will happen pretty often, thereby making the unconditional fetch during
"git submodule update" unnecessary.
If the commit is not present in the submodule (e.g. the user disabled the
fetch on-demand mode) the fetch will be run as before.

fetch/pull: recurse into submodules when necessary
To be able to access all commits of populated submodules referenced by the
superproject it is sufficient to only then let "git fetch" recurse into a
submodule when the new commits fetched in the superproject record new
commits for it. Having these commits present is extremely useful when
using the "--submodule" option to "git diff" (which is what "git gui" and
"gitk" do since 1.6.6), as all submodule commits needed for creating a
descriptive output can be accessed. Also merging submodule commits (added
in 1.7.3) depends on the submodule commits in question being present to
work. Last but not least this enables disconnected operation when using
submodules, as all commits necessary for a successful "git submodule
update -N" will have been fetched automatically. So we choose this mode as
the default for fetch and pull.
Before a new or changed ref from upstream is updated in update_local_ref()
"git rev-list <new-sha1> --not --branches --remotes" is used to determine
all newly fetched commits. These are then walked and diffed against their
parent(s) to see if a submodule has been changed. If that is the case, its
path is stored to be fetched after the superproject fetch is completed.
Using the "--recurse-submodules" or the "--no-recurse-submodules" option
disables the examination of the fetched refs because the result will be
ignored anyway.
There is currently no infrastructure for storing deleted and new
submodules in the .git directory of the superproject. That's why fetch and
pull for now only fetch submodules that are already checked out and are
not renamed.
In t7403 the "--no-recurse-submodules" argument had to be added to "git
pull" to avoid failure because of the moved upstream submodule repo.

SubmittingPatches: clarify the expected commit log description
Earlier, 47afed5 (SubmittingPatches: itemize and reflect upon well written

"contrast". Also mildly discourage external references.
The description was unclear if -c or --cc was the default (--cc is for
some commands), and incorrectly implied that the default applies to
all the diff generating commands.
Most importantly, "log" does not default to "--cc" (it defaults to
"--no-merges") and "log -p" obeys the user's wish to see non-combined
format. Only "diff" (during merge and three-blob comparison) and

This shows a trace of all packets coming in or out of a given
program. This can help with debugging object negotiation or
other protocol issues.
To keep the code changes simple, we operate at the lowest
level, meaning we don't necessarily understand what's in the
packets. The one exception is a packet starting with "PACK",
which causes us to skip that packet and turn off tracing
(since the gigantic pack data will not be interesting to
read, at least not in the trace format).
We show both written and read packets. In the local case,
this may mean you will see packets twice (written by the
sender and read by the receiver). However, for cases where
the other end is remote, this allows you to see the full
conversation.
Packet tracing can be enabled with GIT_TRACE_PACKET=<foo>,

i18n: do not poison translations unless GIT_GETTEXT_POISON envvar is set
Tweak the GETTEXT_POISON facility so it is activated at run time
instead of compile time. If the GIT_GETTEXT_POISON environment
variable is set, _(msg) will result in gibberish as before; but if the
GIT_GETTEXT_POISON variable is not set, it will return the message for
human-readable output. So the behavior of mistranslated and
untranslated git can be compared without rebuilding git in between.
For simplicity we always set the GIT_GETTEXT_POISON variable in tests.
This does not affect builds without the GETTEXT_POISON compile-time

Add a new GETTEXT_POISON compile-time parameter to make _(msg) always
return gibberish. So now you can run
make GETTEXT_POISON=YesPlease
to get a copy of git that functions correctly (one hopes) but produces
output that is in nobody's native language at all.
This is a debugging aid for people who are working on the i18n part of
the system, to make sure that they are not marking plumbing messages
that should never be translated with _().
As new strings get marked for translation, naturally a number of tests
will be broken in this mode. Tests that depend on output from
Porcelain will need to be marked with the new C_LOCALE_OUTPUT test
prerequisite. Newly failing tests that do not depend on output from
Porcelain would be bugs due to messages that should not have been
marked for translation.
Note that the string we're using ("# GETTEXT POISON #") intentionally
starts the pound sign. Some of Git's tests such as
t3404-rebase-interactive.sh rely on interactive editing with a fake
editor, and will needlessly break if the message doesn't start with
something the interactive editor considers a comment.
A future patch will fix fix the underlying cause of that issue by
adding "#" characters to the commit advice automatically.

The _ function is for translating strings into the user's chosen
language. The N_ macro just marks translatable strings for the
xgettext(1) tool without translating them; it is intended for use in
contexts where a function call cannot be used. So, for example:
fprintf(stderr, _("Expansion of alias '%s' failed; "
"'%s' is not a git command\n"),
cmd, argv[0]);
and
const char *unpack_plumbing_errors[NB_UNPACK_TREES_ERROR_TYPES] = {
/* ERROR_WOULD_OVERWRITE */
N_("Entry '%s' would be overwritten by merge. Cannot merge."),
[...]
Define such _ and N_ in a new gettext.h and include it in cache.h, so
they can be used everywhere. Each just returns its argument for now.
_ is a function rather than a macro like N_ to avoid the temptation to
use _("foo") as a string literal (which would be a compile-time error
once _(s) expands to an expression for the translation of s).

vcs-svn: set up channel to read fast-import cat-blob response
Set up some plumbing: teach the svndump lib to pass a file descriptor
number to the fast_export lib, representing where cat-blob/ls
responses can be read from, and add a get_response_line helper
function to the fast_export lib to read a line from that file.
Unfortunately this means that svn-fe needs file descriptor 3 to be
redirected from somewhere (preferrably the cat-blob stream of a
fast-import backend); otherwise it will fail:
$ svndump <path> | svn-fe
fatal: cannot read from file descriptor 3: Bad file descriptor
For the moment, "svn-fe 3</dev/null" works as a workaround but it
will not work for very long. A fast-import backend that can retrieve
old commits is needed in order to be able to fulfill svn
"Node-copyfrom-rev" requests that refer to revs from a previous run.

svn-fe processes each commit in two stages: first decide on the
correct content for all paths and export the relevant blobs, then
export a commit with the result.
But we can keep less state and simplify svn-fe a great deal by
exporting the commit in one step: use 'inline' blobs for each path and
remember nothing. This way, the repo_tree structure could be
eliminated, and we would get support for incremental imports 'for
free'.

vcs-svn: introduce repo_read_path to check the content at a path
The repo_tree structure remembers, for each path in each revision, a
mode (regular file, executable, symlink, or directory) and content
(blob mark or directory structure). Maintaining a second copy of all
this information when it's already in the target repository is
wasteful, it does not persist between svn-fe invocations, and most
importantly, there is no convenient way to transfer it from one
machine to another. So it would be nice to get rid of it.
As a first step, let's change the repo_tree API to match fast-import's
read commands more closely. Currently to read the mode for a path,
one uses
repo_modify_path(path, new_mode, new_content);
which changes the mode and content as a side effect. There is no
function to read the content at a path; add one.

When the line number the patch intended to touch does not match
the line in the version being patched, GNU patch reports that
it applied the hunk at a different line number, with how big an
offset.
Teach "git apply" to do the same under --verbose option.

diffcore-rename: improve estimate_similarity() heuristics
diffcore-rename: properly honor the difference between -M and -C
for_each_hash: allow passing a 'void *data' pointer to callback
apply: do not patch lines that were already patched
When looking for a place to apply a hunk, we used to check lines that
match the preimage of it, starting from the line that the patch wants to
apply the hunk at, looking forward and backward with increasing offsets
until we find a match.
Colin Guthrie found an interesting case where this misapplied a patch that
wanted to touch a preimage that consists of
}
}
return 0;
}
which is a rather unfortunately common pattern.
The target version of the file originally had only one such location, but
the hunk immediately before that created another instance of such block of
lines, and find_pos() happily reported that the preimage of the hunk
matched what it wanted to modify.
Oops.
By marking the lines application of earlier hunks touched and preventing
match_fragment() from considering them as a match with preimage of other
hunks, we can reduce such an accident.
I also considered to teach apply_one_fragment() to take the offset we have
found while applying the previous hunk into account when looking for a
match with find_pos(), but dismissed that approach, because it would
sometimes work better but sometimes worse, depending on the difference
between the version the patch was created against and the version the
patch is being applied.
This does _not_ prevent misapplication of patches to a file that has many
similar looking blocks of lines and a preimage cannot identify which one
of them should be applied. For that, we would need to scan beyond the
first match in find_pos(), and issue a warning (or error out). That will
be a separate topic.
git_dir must always be non-NULL so "if (git_dir)" is unnecessary.
Before this code, if git_dir == NULL, it will default to
DEFAULT_GIT_DIR_ENVIRONMENT.

push: better error messages when push.default = tracking
A common scenario is to create a new branch and push it (checkout -b &&
push [--set-upstream]). In this case, the user was getting "The current
branch %s has no upstream branch.", which doesn't help much.
Provide the user a command to push the current branch. To avoid the
situation in the future, suggest --set-upstream.
While we're there, also improve the error message in the "detached HEAD"
case. We mention explicitly "detached HEAD" since this is the keyword to
look for in documentations.

get_remote_url(): use the same data source as ls-remote to get remote urls
The formerly implemented algorithm behaved differently to
remote.c:remote_get() at least for remotes that contain a slash. While the
former just assumes a/b is a path the latter checks the config for
remote."a/b" first which is more reasonable.
This removes the last user of git-parse-remote.sh:get_data_source(), so
this function is removed.

rerere forget: deprecate invocation without pathspec
rerere forget is a destructive command. When invoked without a path, it
operates on the current directory, potentially deleting many recorded
conflict resolutions.
To make the command safer, a path must be specified as of git 1.8.0. Until
then, give users time to write 'git rerere forget .' if they really mean
the entire current directory.

If a pack file is small enough that its entire contents fits within
one mmap window, mmap the file and then immediately close its file
descriptor. This reduces the number of file descriptors that are
needed to read from repositories with many tiny pack files, such
as one that has received 1000 pushes (and created 1000 small pack
files) since its last repack.

Rather than using 'errno == EMFILE' after a failed open() call
to indicate the process is out of file descriptors and an LRU
pack window should be closed, place a hard upper limit on the
number of open packs based on the actual rlimit of the process.
By using a hard upper limit that is below the rlimit of the current
process it is not necessary to check for EMFILE on every single
fd-allocating system call. Instead reserving 25 file descriptors
makes it safe to assume the system call won't fail due to being over
the filedescriptor limit. Here 25 is chosen as a WAG, but considers
3 for stdin/stdout/stderr, and at least a few for other Git code
to operate on temporary files. An additional 20 is reserved as it
is not known what the C library needs to perform other services on
Git's behalf, such as nsswitch or name resolution.
This fixes a case where running `git gc --auto` in a repository
with more than 1024 packs (but an rlimit of 1024 open fds) fails
due to the temporary output file not being able to allocate a
file descriptor. The output file is opened by pack-objects after
object enumeration and delta compression are done, both of which
have already opened all of the packs and fully populated the file
descriptor table.
