This patch adds an alternative implementation of show_dirstat(), called
show_dirstat_by_line(), which uses the more expensive diffstat analysis
(as opposed to show_dirstat()'s own (relatively inexpensive) analysis)
to derive the numbers from which the --dirstat output is computed.
The alternative implementation is controlled by the new "lines" parameter
to the --dirstat option (or the diff.dirstat config variable).
For binary files, the diffstat analysis counts bytes instead of lines,
so to prevent binary files from dominating the dirstat results, the
byte counts for binary files are divided by 64 before being compared to
their textual/line-based counterparts. This is a stupid and ugly - but
very cheap - heuristic.
In linux-2.6.git, running the three different --dirstat modes:
time git diff v2.6.20..v2.6.30 --dirstat=changes > /dev/null
vs.
time git diff v2.6.20..v2.6.30 --dirstat=lines > /dev/null
vs.
time git diff v2.6.20..v2.6.30 --dirstat=files > /dev/null
yields the following average runtimes on my machine:
- "changes" (default): ~6.0 s
- "lines": ~9.6 s
- "files": ~0.1 s
So, as expected, there's a considerable performance hit (~60%) by going
through the full diffstat analysis as compared to the default "changes"
analysis (obviously, "files" is much faster than both). As such, the
"lines" mode is probably only useful if you really need the --dirstat
numbers to be consistent with the numbers returned from the other
--*stat options.
The patch also includes documentation and tests for the new dirstat mode.

The new diff.dirstat config variable takes the same arguments as
'--dirstat=<args>', and specifies the default arguments for --dirstat.
The config is obviously overridden by --dirstat arguments passed on the
command line.
When not specified, the --dirstat defaults are 'changes,noncumulative,3'.
The patch also adds several tests verifying the interaction between the
diff.dirstat config variable, and the --dirstat command line option.

Instead of having multiple interconnected dirstat-related options, teach
the --dirstat option itself to accept all behavior modifiers as parameters.
- Preserve the current --dirstat=<limit> (where <limit> is an integer
specifying a cut-off percentage)
- Add --dirstat=cumulative, replacing --cumulative
- Add --dirstat=files, replacing --dirstat-by-file
- Also add --dirstat=changes and --dirstat=noncumulative for specifying the
current default behavior. These allow the user to reset other --dirstat
parameters (e.g. 'cumulative' and 'files') occuring earlier on the
command line.
The deprecated options (--cumulative and --dirstat-by-file) are still
functional, although they have been removed from the documentation.
Allow multiple parameters to be separated by commas, e.g.:
--dirstat=files,10,cumulative
Update the documentation accordingly, and add testcases verifying the
behavior of the new syntax.

The expected output from --dirstat=0, is to include any directory with
changes, even if those changes contribute a minuscule portion of the total
changes. However, currently, directories that contribute less than 0.1% are
not included, since their 'permille' value is 0, and there is an
'if (permille)' check in gather_dirstat() that causes them to be ignored.
This test is obviously intended to exclude directories that contribute no
changes whatsoever, but in this case, it hits too broadly. The correct
check is against 'this_dir' from which the permille is calculated. Only if
this value is 0 does the directory truly contribute no changes, and should
be skipped from the output.
This patches fixes this issue, and updates corresponding testcases to
expect the new behvaior.

Currently, t4013 is the only selftest that exercises the --dirstat machinery,
but it only does a superficial verification of --dirstat's output.
This patch adds a new selftest - t4047-diff-dirstat.sh - which prepares a
commit containing:
- unchanged files, changed files and files with rearranged lines
- copied files, moved files, and unmoved files
It then verifies the correct dirstat output for that commit in the following
dirstat modes:
- --dirstat
- -X
- --dirstat=0
- -X0
- --cumulative
- --dirstat-by-file
- (plus combinations of the above)
Each of the above tests are also run with:
- no rename detection
- rename detection (-M)
- expensive copy detection (-C -C)

The names and e-mails are sanitized by fmt_ident() when creating commits,
so that they do not contain "<" nor ">", and the "committer" and "author"
lines in the commit object will always be in the form:
("author" | "committer") name SP "<" email ">" SP timestamp SP zone
When parsing the email part out, the current code looks for SP starting
from the end of the email part, but the author could obfuscate the address
as "author at example dot com".
We should instead look for SP followed by "<", to match the logic of the

'git rebase' uses 'git merge' to preserve merges (-p). This preserves
the original merge commit correctly, except when the original merge
commit was created by 'git merge --no-ff'. In this case, 'git rebase'
will fail to preserve the merge, because during 'git rebase', 'git
merge' will simply fast-forward and skip the commit. For example:
B
/ \
A---M
/
---o---O---P---Q
If we try to rebase M onto P, we lose the merge commit and this happens:
A---B
/
---o---O---P---Q
To correct this, we simply do a "no fast-forward" on all merge commits
when rebasing. Since by the time we decided to do a 'git merge' inside
'git rebase', it means there was a merge originally, so 'git merge'
should always create a merge commit regardless of what the merge
branches look like. This way, when rebase M onto P from the above
example, we get:
B
/ \
A---M
/
---o---O---P---Q

If somebody has a name that includes an rfc822 special, we
will output it literally in the "From:" header. This is
usually OK, but certain characters (like ".") are supposed
to be enclosed in double-quotes in a mail header.
In practice, whether this matters may depend on your MUA.
Some MUAs will happily take in:
From: Foo B. Bar <author@example.com>
without quotes, and properly quote the "." when they send
the actual mail. Others may not, or may screw up harder
things like:
From: Foo "The Baz" Bar <author@example.com>
For example, mutt will strip the quotes, thinking they are
actual syntactic rfc822 quotes.
So let's quote properly, and then (if necessary) we still
apply rfc2047 encoding on top of that, which should make all
MUAs happy.

"git add -u" updates the index with the updated contents from the working
tree by internally running "diff-files" to grab the set of paths that are
different from the index. Then it updates the index entries for the paths
that are modified in the working tree, and deletes the index entries for
the paths that are deleted in the working tree.
It ignored the output from the diff-files that indicated that a path is
unmerged. For these paths, it instead relied on the fact that an unmerged
path is followed by the result of comparison between stage #2 (ours) and
the working tree, and used that to update or delete such a path when it is
used to record the resolution of a conflict.
As the result, when a path did not have stage #2 (e.g. "we deleted while
the other side added"), these unmerged stages were left behind, instead of
recording what the user resolved in the working tree.
Since we recently fixed "diff-files" to indicate if the corresponding path
exists on the working tree for an unmerged path, we do not have to rely on
the comparison with stage #2 anymore. We can instead tell the diff-files
not to compare with higher stages, and use the unmerged output to update
the index to reflect the state of the working tree.
The changes to the test vector in t2200 illustrates the nature of the bug
and the fix. The test expected stage #1 and #3 entries be left behind,
but it was codifying the buggy behaviour.

When relative dates are more than about a year ago, we start
writing them as "Y years, M months". At the point where we
calculate Y and M, we have the time delta specified as a
number of days. We calculate these integers as:
Y = days / 365
M = (days % 365 + 15) / 30
This rounds days in the latter half of a month up to the
nearest month, so that day 16 is "1 month" (or day 381 is "1
year, 1 month").
We don't round the year at all, though, meaning we can end
up with "1 year, 12 months", which is silly; it should just
be "2 years".
Implement this differently with months of size
onemonth = 365/12
so that
totalmonths = (long)( (days + onemonth/2)/onemonth )
years = totalmonths / 12
months = totalmonths % 12
In order to do this without floats, we write the first formula as
totalmonths = (days*12*2 + 365) / (365*2)

Add some tests to make sure it doesn't happen again.

on Windows the bash spawned by git converts LF to CRLF in text written
by echo while the bash running tests does not, causing the test to

We already wrap names in "from" headers, which tend to be
the long part of an address. But it's also possible for a
long name to not be wrapped, but to make us want to wrap the
email address. For example (imagine for the sake of
readability we want to wrap at 50 characters instead of 78):
From: this is my really long git name <foo@example.com>
The name does not overflow the line, but the name and email
together do. So we would rather see:
From: this is my really long git name
<git@example.com>
Because we wrap the name separately during add_rfc2047, we
neglected this case. Instead, we should see how long the
final line of the wrapped name ended up, and decide whether
or not to wrap based on that. We can't break the address
into multiple parts, so we either leave it with the name, or
put it by itself on a line.

However, if the object name has changed, we already know that there is
some damage, and it is unintuitive to claim there is _no_ damage.
Teach show_dirstat() to assign a minimum amount of damage (== 1) to
entries for which the analysis otherwise yields zero damage, to still
represent that these files are changed, instead of saying that there
is no change.

Currently, when using --dirstat-by-file, it first does the full --dirstat
analysis (using diffcore_count_changes()), and then resets 'damage' to 1,
if any damage was found by diffcore_count_changes().
But --dirstat-by-file is not interested in the file damage per se. It only
cares if the file changed at all. In that sense it only cares if the blob
object for a file has changed. We therefore only need to compare the
object names of each file pair in the diff queue and we can skip the
entire --dirstat analysis and simply set 'damage' to 1 for each entry
where the object name has changed.
This makes --dirstat-by-file faster, and also bypasses --dirstat's practice
of ignoring rearranged lines within a file.

Before we apply a stash, we make sure there are no changes

back to the original git-stash.sh, and is presumably
intended to prevent changes in the working tree from being

However, this check has two problems:
1. It is overly restrictive. If my stash changes only file
"foo", but "bar" is dirty in the working tree, it will
prevent us from applying the stash.
2. It is redundant. We don't touch the working tree at all
until we actually call merge-recursive. But it has its
own (much more accurate) checks to avoid losing working

Once upon a time, "git rev-parse ref@{9999999}" did not

reference in "stash apply", we could end up not noticing
until quite late. Commit b0f0ecd (detached-stash: work
around git rev-parse failure to detect bad log refs,
2010-08-21) handled this by checking for the "Log for stash
has only %d entries" warning on stderr when we validated the
ref.
A few days later, e6eedc3 (rev-parse: exit with non-zero
status if ref@{n} is not valid., 2010-08-24) fixed the
original issue. That made the extra stderr test superfluous,
but also introduced a new bug. Now the early call to:
git rev-parse --symbolic "$@"
fails, but we don't notice the exit code. Worse, its empty
output means we think the user didn't provide us a ref, and
we try to apply stash@{0}.
This patch checks the rev-parse exit code and fails early in
the revision parsing process. We can also get rid of the
stderr test; as a bonus, this means that "stash apply" can
now run under GIT_TRACE=1 properly.

When reviewing a patch while concentrating primarily on the text after
then change, wading through pages of deleted text involves a cognitive
burden.
Introduce the -D option that omits the preimage text from the patch output
for deleted files. When used with -B (represent total rewrite as a single
wholesale deletion followed by a single wholesale addition), the preimage
text is also omitted.
To prevent such a patch from being applied by mistake, the output is
designed not to be usable by "git apply" (or GNU "patch"); it is strictly
for human consumption.
It of course is possible to "apply" such a patch by hand, as a human can
read the intention out of such a patch. It however is impossible to apply
such a patch even manually in reverse, as the whole point of this option
is to omit the information necessary to do so from the output.

During a merge module_list returns conflicting submodules several times
(stage 1,2,3) which caused the submodules to be used multiple times in
git submodule init, sync, update and status command.
There are 5 callers of module_list; they all read (mode, sha1, stage,
path) tuple, and most of them care only about path. As a first level
approximation, it should be Ok (in the sense that it does not make things
worse than it currently is) to filter the duplicate paths from module_list
output, but some callers should change their behaviour when the merge in
the superproject still has conflicts.
Notice the higher-stage entries, and emit only one record from
module_list, but while doing so, mark the entry with "U" (not [0-3]) in
the $stage field and null out the SHA-1 part, as the object name for the
lowest stage does not give any useful information to the caller, and this
way any caller that uses the object name would hopefully barf. Then
update the codepaths for each subcommands this way:
- "update" should not touch the submodule repository, because we do not
know what commit should be checked out yet.
- "status" reports the conflicting submodules as 'U000...000' and does
not recurse into them (we might later want to make it recurse).
- The command called by "foreach" may want to do whatever it wants to do
by noticing the merged status in the superproject itself, so feed the
path to it from module_list as before, but only once per submodule.
- "init" and "sync" are unlikely things to do while the superproject is
still not merged, but as long as a submodule is there in $path, there
is no point skipping it. It might however want to take the merged
status of .gitmodules into account, but that is outside of the scope of
this topic.

git-remote currently has one option, "--mirror", which sets
up mirror configuration which can be used for either
fetching or pushing. It looks like this:
[remote "mirror"]
url = wherever
fetch = +refs/*:refs/*
mirror = true
However, a remote like this can be dangerous and confusing.
Specifically:
1. If you issue the wrong command, it can be devastating.
You are not likely to "push" when you meant to "fetch",
but "git remote update" will try to fetch it, even if
you intended the remote only for pushing. In either
case, the results can be quite destructive. An
unintended push will overwrite or delete remote refs,
and an unintended fetch can overwrite local branches.
2. The tracking setup code can produce confusing results.
The fetch refspec above means that "git checkout -b new
master" will consider refs/heads/master to come from
the remote "mirror", even if you only ever intend to
push to the mirror. It will set up the "new" branch to
track mirror's refs/heads/master.
3. The push code tries to opportunistically update
tracking branches. If you "git push mirror foo:bar",
it will see that we are updating mirror's
refs/heads/bar, which corresponds to our local
refs/heads/bar, and will update our local branch.
To solve this, we split the concept into "push mirrors" and
"fetch mirrors". Push mirrors set only remote.*.mirror,
solving (2) and (3), and making an accidental fetch write
only into FETCH_HEAD. Fetch mirrors set only the fetch
refspec, meaning an accidental push will not force-overwrite
or delete refs on the remote end.
The new syntax is "--mirror=<fetch|push>". For
compatibility, we keep "--mirror" as-is, setting up both
types simultaneously.

Currently, "notes add" (without -f/--force) will abort when the given object
already has existing notes. This makes sense for the modes of "git notes add"
that would necessarily overwrite the old message (when using the -m/-F/-C/-c
options). However, when no options are given (meaning the notes are created
from scratch in the editor) it is not very user-friendly to abort on existing
notes, and forcing the user to run "git notes edit".
Instead, it is better to simply "redirect" to "git notes edit" automatically,
i.e. open the existing notes in the editor and let the user edit them.
This patch does just that.
This changes the behavior of "git notes add" without options when notes
already exist for the given object, but I doubt that many users really depend
on the previous failure from "git notes add" in this case.

* 'svn-fe' of git://repo.or.cz/git/jrn:
tests: kill backgrounded processes more robustly
vcs-svn: a void function shouldn't try to return something
tests: make sure input to sed is newline terminated
vcs-svn: add missing cast to printf argument
t0081 creates several background processes that write to a fifo and
then go to sleep for a while (so the reader of the fifo does not see
EOF).
Each background process is made in a curly-braced block in the shell,
and after we are done reading from the fifo, we use "kill $!" to kill
it off.
For a simple, single-command process, this works reliably and kills
the child sleep process. But for more complex commands like
"make_some_output && sleep", the results are less predictable. When
executing under bash, we end up with a subshell that gets killed by
the $! but leaves the sleep process still alive.
This is bad not only for process hygeine (we are leaving random sleep
processes to expire after a while), but also interacts badly with the
"prove" command. When prove executes a test, it does not realize the
test is done when it sees SIGCHLD, but rather waits until the test's
stdout pipe is closed. The orphaned sleep process may keep that pipe
open via test-lib's file descriptor 5, causing prove to hang for 100
seconds.
The solution is to explicitly use a subshell and to exec the final
sleep process, so that when we "kill $!" we get the process id of the
sleep process.
[jn: original patch by Jeff had some additional bits:
1. Wrap the "kill" in a test_when_finished, since we want
to clean up the process whether the test succeeds or not.
2. The "kill" is part of our && chain for test success. It
probably won't fail, but it can if the process has
expired before we manage to kill it. So let's mark it
as OK to fail.
I'm postponing that for now.]

"GIT_USE_LOOKUP".
Unfortunately some environment variables used by the test framework itself

- GIT_NOTES_TIMING_TESTS
- GIT_PATCHID_TIMING_TESTS
- GIT_PROVE_OPTS

- GIT_SKIP_TESTS
- GIT_TEST*
- GIT_VALGRIND_OPTIONS

that by adding them to the exception list. And to avoid having a long

svn-fe errors out on revision 59151 of the ASF repository:
fatal: invalid dump: unexpected end of file
The proximate cause is a property with an embedded NUL character.
Previously such anomalies were ignored but commit c9d1c8ba
(2010-12-28) introduced a check strlen(val) == len to avoid reading
uninitialized data when a property list ends early and unfortunately
this test does not distinguish between "foo" followed by EOF and the
string "foo\0bar\0baz".
Fix it by using buffer_read_binary to read to a strbuf and checking
the actual length read. Most consumers of properties still use
C-style strings, so in practice an author or log message with embedded
NULs will be truncated, but a least this way svn-fe won't error out
(fixing the regression).

When we merge into an unborn branch, there are basically two
steps:
1. Write the sha1 of the new commit into the ref pointed
to by HEAD.
2. Update the index with the new content, and check it out
to the working tree.
We currently do them in this order. However, (2) is the step
that is much more likely to fail, since it can be blocked by
things like untracked working tree files. When it does, the
merge fails and we are left with an empty index but an
updated HEAD.
This patch switches the order, so that a failure in updating
the index leaves us unchanged. Of course, a failure in
updating the ref now leaves us with an updated index and
mis-matched HEAD. That is arguably not much better, but it
is probably less likely to actually happen.

Since e9c8409 (diff-index --cached --raw: show tree entry on the LHS for
unmerged entries., 2007-01-05), an unmerged entry should be detected by
using DIFF_PAIR_UNMERGED(p), not by noticing both one and two sides of
the filepair records mode=0 entries. However, it forgot to update some
parts of the rename detection logic.
This only makes difference in the "diff --cached" codepath where an
unmerged filepair carries information on the entries that came from the
tree. It probably hasn't been noticed for a long time because nobody
would run "diff -M" during a conflict resolution, but "git status" uses
rename detection when it internally runs "diff-index" and "diff-files"
and gives nonsense results.
In an unmerged pair, "one" side can have a valid filespec to record the
tree entry (e.g. what's in HEAD) when running "diff --cached". This can
be used as a rename source to other paths in the index that are not
unmerged. The path that is unmerged by definition does not have the
final content yet (i.e. "two" side cannot have a valid filespec), so it
can never be a rename destination.
Use the DIFF_PAIR_UNMERGED() to detect unmerged filepair correctly, and
allow the valid "one" side of an unmerged filepair to be considered a
potential rename source, but never to be considered a rename destination.

The git-new-workdir script in contrib/ makes a new work tree by sharing
many subdirectories of the .git directory with the original repository.
When rerere.enabled is set in the original repository, but the user has
not encountered any conflicts yet, the original repository may not yet
have .git/rr-cache directory.
When rerere wants to run in a new work tree created from such a young
original repository, it fails to mkdir(2) .git/rr-cache that is a symlink
to a yet-to-be-created directory.
There are three possible approaches to this:
- A naive solution is not to create a symlink in the git-new-workdir
script to a directory the original does not have (yet). This is not a
solution, as we tend to lazily create subdirectories of .git/, and
having rerere.enabled configuration set is a strong indication that the
user _wants_ to have this lazy creation to happen;
- We could always create .git/rr-cache upon repository creation. This is
tempting but will not help people with existing repositories.
- Detect this case by seeing that mkdir(2) failed with EEXIST, checking
that the path is a symlink, and try running mkdir(2) on the link
target.
This patch solves the issue by doing the third one.
Strictly speaking, this is incomplete. It does not attempt to handle
relative symbolic link that points into the original repository, but this
is good enough to help people who use contrib/workdir/git-new-workdir
script.

The receiving end of "git push" advertises the objects that the repository
itself does not use, but are at the tips of refs in other repositories
whose object databases are used as alternates for it. This helps it avoid
having to receive (and the pusher having to send) objects that are already
available to the receiving repository via the alternates mechanism.
Tweak the helper function that implements this feature, and move it to
transport.[ch] for future reuse by other programs.
The additional test demonstrates how this optimization is helping "git push",
and "git fetch" is ignorant about it.

The code notices that the caller does not want any detail of the changes
and only wants to know if there is a change or not by specifying --quiet.
And it breaks out of the loop when it knows it already found any change.
When you have a post-process filter (e.g. --diff-filter), however, the
path we found to be different in the previous round and set HAS_CHANGES
bit may end up being uninteresting, and there may be no output at the end.
The optimization needs to be disabled for such case.
Note that the f245194 (diff: change semantics of "ignore whitespace"
options, 2009-05-22) already disables this optimization by refraining
from setting HAS_CHANGES when post-process filters that need to inspect
the contents of the files (e.g. -S, -w) in diff_change() function.

Some versions of strlen use SSE to speed up the calculation and load 4
bytes at a time, even if it means reading past the end of the
allocated memory. This read is safe and when the strlen function is
inlined, it is not replaced by valgrind, which reports a
false-possitive.
Tell valgrind to ignore this particular error, as the read is, in
fact, safe. Current upstream-released version 3.6.1 is affected. Some
distributions have this fixed in their latest versions.

Variables from the inherited environment that are meaningful to git
can break tests in undesirable ways. For example,
GIT_PAGER=more sh t5400-send-pack.sh -v -i
hangs. So unset all environment variables in the GIT_ namespace in
test-lib, with a few exceptions:
- GIT_TRACE* are useful for tracking down bugs exhibited by a failing
test;
- GIT_DEBUG* are GIT_TRACE variables by another name, practically
speaking. They should probably be tweaked to follow the
GIT_TRACE_foo scheme and use trace_printf machinery some time.
- GIT_USE_LOOKUP from v1.5.6-rc0~134^2~1 (sha1-lookup: more memory

trying an alternate implementation strategy rather than changing

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.

Until now the --recurse-submodules option could only be used to either
fetch all populated submodules recursively or to disable recursion
completely. As fetch and pull now by default just fetch those submodules
for which new commits have been fetched in the superproject, a command
line option to enforce that behavior is needed to be able to override
configuration settings.

Signed-off-by: Junio C Hamano <gitster@pobox.com>
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.

Tweak the GETTEXT_POISON facility so it is activated at run time

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.

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.

diffcore-rename: improve estimate_similarity() heuristics

for_each_hash: allow passing a 'void *data' pointer to callback
In 882fd11 (merge-recursive: Delay content merging for renames 2010-09-20),
there was code that checked for whether we could skip updating a file in
the working directory, based on whether the merged version matched the
current working copy. Due to the desire to handle directory/file conflicts
that were resolvable, that commit deferred content merging by first
updating the index with the unmerged entries and then moving the actual
merging (along with the skip-the-content-update check) to another function
that ran later in the merge process. As part moving the content merging
code, a bug was introduced such that although the message about skipping
the update would be printed (whenever GIT_MERGE_VERBOSITY was sufficiently
high), the file would be unconditionally updated in the working copy
anyway.
When we detect that the file does not need to be updated in the working
copy, update the index appropriately and then return early before updating
the working copy.

buffer_read_string works well for non line-oriented input except for
one problem: it does not tell the caller how many bytes were actually
written. This means that unless one is very careful about checking
for errors (and eof) the calling program cannot tell the difference
between the string "foo" followed by an early end of file and the
string "foo\0bar\0baz".
So introduce a variant that reports the length, too, a thinner wrapper
around strbuf_fread. Its result is written to a strbuf so the caller
does not need to keep track of the number of bytes read.

POSIX makes the behavior of read(2) from a pipe fairly clear: a read
from an empty pipe will block until there is data available and any
other read will not block, prefering to return a partial result.
Likewise, fread(3) and fgets(3) are clearly specified to act as
though implemented by calling fgetc(3) in a simple loop. But the
buffering behavior of fgetc is less clear.
Luckily, no sane platform is going to implement fgetc by calling the
equivalent of read(2) more than once. fgetc has to be able to
return without filling its buffer to preserve errno when errors are
encountered anyway. So let's assume the simpler behavior (trust) but
add some tests to catch insane platforms that violate that when they
come (verify).
First check that fread can handle a 0-length read from an empty fifo.
Because open(O_RDONLY) blocks until the writing end is open, open the
writing end of the fifo in advance in a subshell.
Next try short inputs from a pipe that is not filled all the way.
Lastly (two tests) try very large inputs from a pipe that will not fit
in the relevant buffers. The first of these tests reads a little
more than 8192 bytes, which is BUFSIZ (the size of stdio's buffers)
on this Linux machine. The second reads a little over 64 KiB (the
pipe capacity on Linux) and is not run unless requested by setting
the GIT_REMOTE_SVN_TEST_BIG_FILES environment variable.

Lazy fast-import frontend authors that want to rely on the backend to
keep track of the content of the imported trees _almost_ have what
they need in the 'cat-blob' command (v1.7.4-rc0~30^2~3, 2010-11-28).
But it is not quite enough, since
(1) cat-blob can be used to retrieve the content of files, but
not their mode, and
(2) using cat-blob requires the frontend to keep track of a name
(mark number or object id) for each blob to be retrieved
Introduce an 'ls' command to complement cat-blob and take care of the
remaining needs. The 'ls' command finds what is at a given path
within a given tree-ish (tag, commit, or tree):
'ls' SP <dataref> SP <path> LF
or in fast-import's active commit:
'ls' SP <path> LF
The response is a single line sent through the cat-blob channel,
imitating ls-tree output. So for example:
FE> ls :1 Documentation
gfi> 040000 tree 9e6c2b599341d28a2a375f8207507e0a2a627fe9 Documentation
FE> ls 9e6c2b599341d28a2a375f8207507e0a2a627fe9 git-fast-import.txt
gfi> 100644 blob 4f92954396e3f0f97e75b6838a5635b583708870 git-fast-import.txt
FE> ls :1 RelNotes
gfi> 120000 blob b942e49944 RelNotes
FE> cat-blob b942e49944
gfi> b942e49944 blob 32
gfi> Documentation/RelNotes/1.7.4.txt
The most interesting parts of the reply are the first word, which is
a 6-digit octal mode (regular file, executable, symlink, directory,
or submodule), and the part from the second space to the tab, which is
a <dataref> that can be used in later cat-blob, ls, and filemodify (M)
commands to refer to the content (blob, tree, or commit) at that path.
If there is nothing there, the response is "missing some/path".
The intent is for this command to be used to read files from the
active commit, so a frontend can apply patches to them, and to copy
files and directories from previous revisions.
For example, proposed updates to svn-fe use this command in place of
its internal representation of the repository directory structure.
This simplifies the frontend a great deal and means support for
resuming an import in a separate fast-import run (i.e., incremental
import) is basically free.

When "git commit" was rewritten in C (v1.5.4-rc0~78^2~30,
2007-11-08), a subtle bug in --template was introduced. If the
file named by a --template parameter is missing, previously git
would error out with a message:

but in the C version the --template parameter gets ignored and
the default template is used.

that with the default $EDITOR, the commit message template is left
unmodified, causing 'git commit' to error out and the test to

Subject and identity headers may be arbitrarily long. In the
past, we just assumed that single-line headers would be
reasonably short. For multi-line subjects that we squish
into a single line, we just "pre-folded" the data in
pp_title_line by adding a newline and indentation.
There were two problems. One is that, although rare,
single-line messages can actually be longer than the
recommended line-length limits. The second is that the
pre-folding interacted badly with rfc2047 encoding, leading
to malformed headers.
Instead, let's stop pre-folding the subject lines, and just
fold everything based on length in add_rfc2047, whether
it is encoded or not.

Sanity-check config variable names when adding and retrieving them. As a side

This breaks a test in t1300 which used invalid section-less keys in the tests

no way to set them via config file, and no part of git actually tried to use
section-less keys. This patch updates the test to use more realistic examples

The logic in builtin_diffstat assumes that a
complete_rewrite pair should have its lines counted. This is
nonsensical for binary files and leads to confusing things
like:
$ git diff --stat --summary HEAD^ HEAD
foo.rand | Bin 4096 -> 4096 bytes
1 files changed, 0 insertions(+), 0 deletions(-)
$ git diff --stat --summary -B HEAD^ HEAD
foo.rand | 34 +++++++++++++++-------------------
1 files changed, 15 insertions(+), 19 deletions(-)
rewrite foo.rand (100%)
So let's reorder the function to handle binary files first
(which from diffstat's perspective look like complete
rewrites anyway), then rewrites, then actual diffstats.
There are two bonus prizes to this reorder:
1. It gets rid of a now-superfluous goto.
2. The binary case is at the top, which means we can
further optimize it in the next patch.

Previously the user was advised to use commit -c CHERRY_PICK_HEAD after
a conflicting cherry-pick. While this would preserve the original
commit's authorship, it would sadly discard cherry-pick's carefully
crafted MERGE_MSG (which contains the list of conflicts as well as the
original commit-id in the case of cherry-pick -x).
On the other hand, if a bare 'commit' were performed, it would preserve
the MERGE_MSG while resetting the authorship.
In other words, there was no way to simultaneously take the authorship
from CHERRY_PICK_HEAD and the commit message from MERGE_MSG.
This change fixes that situation. A bare 'commit' will now take the
authorship from CHERRY_PICK_HEAD and the commit message from MERGE_MSG.
If the user wishes to reset authorship, that must now be done explicitly
via --reset-author.
A side-benefit of passing commit authorship along this way is that we
can eliminate redundant authorship parsing code from revert.c.

When a cherry-pick conflicts git advises:
$ git commit -c <original commit id>
to preserve the original commit message and authorship. Instead, let's
record the original commit id in CHERRY_PICK_HEAD and advise:
$ git commit -c CHERRY_PICK_HEAD
A later patch teaches git to handle the '-c CHERRY_PICK_HEAD' part.
Note that we record CHERRY_PICK_HEAD even in the case where there
are no conflicts so that we may use it to communicate authorship to
commit; this will then allow us to remove set_author_ident_env from
revert.c. However, we do not record CHERRY_PICK_HEAD when --no-commit
is used, as presumably the user intends to further edit the commit
and possibly even cherry-pick additional commits on top.

When creating a new branch using the --track option, we must make sure that
we don't try to set an upstream that does not make sense to follow (using
'git pull') or update (using 'git push'). The current code checks against
using HEAD as upstream (since tracking a symref doesn't make sense). However,
tracking a tag doesn't make sense either. Indeed, tracking _any_ ref that is
not a (local or remote) branch doesn't make sense, and should be disallowed.
This patch achieves this by checking that the ref we're trying to --track
resides within refs/heads/* or refs/remotes/*. This new check replaces the
previous check against HEAD.
A couple of testcases are also added, verifying that we cannot create
branches with tags as upstreams.
Finally, some selftests relying on using a non-branch as an upstream have
been reworked or removed:
- t6040: Reverse the meaning of two tests that depend on the ability to
use (lightweight and annotated) tags as upstreams. These two tests were

Since bb0a484 (mergetool: Skip autoresolved paths, 2010-08-17),
mergetool uses different ways of figuring out the list of files with
merge conflicts depending on whether rerere is active. If rerere is
active, mergetool will use 'git rerere status' to list the files with
remaining conflicts. However, the output from that command does not
list conflicts of types that rerere does not handle, such as
modify/remove conflicts.
Another problem with solely relying on the output from 'git rerere
status' is that, for new conflicts that are not yet known to rerere,
the output from the command will list the files even after adding them
to the index. This means that if the conflicts in some files have been
resolved and 'git mergetool' is run again, it will ask the user
something like the following for each of those files.
file1: file does not need merging
Continue merging other unresolved paths (y/n) ?
Solve both of these problems by replacing the call to 'git rerere
status' with a call to the new 'git rerere remaining' that was

When command_input_pipe and command_output_pipe are used as a
method of a Git::repository instance, they eventually call into
_cmd_exec method that sets up the execution environment such as
GIT_DIR, GIT_WORK_TREE environment variables and the current
working directory in the child process that interacts with the
repository.
command_bidi_pipe however didn't expect to be called as such, and
lacked all these set-up. Because of this, a program that did this
did not work as expected:
my $repo = Git->repository(Directory => '/some/where/else');
my ($pid, $in, $out, $ctx) =
$repo->command_bidi_pipe(qw(hash-object -w --stdin-paths));
This patch refactors the _cmd_exec into _setup_git_cmd_env that
sets up the execution environment, and makes _cmd_exec and
command_bidi_pipe to use it.
Note that unlike _cmd_exec that execv's a git command as an
external process, command_bidi_pipe is called from the main line
of control, and the execution environment needs to be restored
after open2() does its magic.

'git rebase' without arguments is currently not supported. Make it
default to 'git rebase @{upstream}'. That is also what 'git pull

defaults to the same thing.
Defaulting to @{upstream} will make it possible to run e.g. 'git
rebase -i' without arguments, which is probably a quite common use
case. It also improves the scenario where you have multiple branches
that rebase against a remote-tracking branch, where you currently have
to choose between the extra network delay of 'git pull' or the
slightly awkward keys to enter 'git rebase @{u}'.
The error reporting when no upstream is configured for the current
branch or when no branch is checked out is reused from git-pull.sh. A
function is extracted into git-parse-remote.sh for this purpose.
