When bisect successfully finds a single revision, the first bad commit
should be shown to human readers of 'git bisect log'.
This resolves the apparent disconnect between the bisection result and
the log when a bug reporter says "I know that the first bad commit is
$rev, as you can see from $(git bisect log)".

This allows a remote helper using the 'export' protocol to specify that
it supports signed tags, changing the handing from 'warn-strip' to
'verbatim'.

Signed-off-by: Junio C Hamano <gitster@pobox.com>
Currently, attempting to push a signed tag to a remote helper which uses
fast-export results in the remote helper failing because the default
fast-export action for signed tags is "abort". This is not helpful for
users because there is no way to pass additional arguments to
fast-export here, either from the remote helper or from the command
line.
In general, the signature will be invalidated by whatever transformation
a remote helper performs on a tag to push it to a repository in a
different format so the correct behaviour is to strip the tag. Doing
this silently may surprise people, so use "warn-strip" to issue a
warning when a signed tag is encountered.

specified, we do not remove the trash directory once the tests are
complete (remove_trash is set to $TRASH_DIRECTORY).
Fix this by always referring to the trash directory as $TRASH_DIRECTORY.

The functionality we use from compgen is not much, we can do the same
manually, with drastic improvements in speed, especially when dealing
with only a few words.
This patch also has the sideffect that brekage reported by Jeroen Meijer
and SZEDER Gábor gets fixed because we no longer expand the resulting
words.
Here are some numbers filtering N amount of words:
== 1 ==
original: 0.002s
new: 0.000s
== 10 ==
original: 0.002s
new: 0.000s
== 100 ==

new: 0.002s
== 1000 ==
original: 0.012s
new: 0.011s
== 10000 ==
original: 0.056s
new: 0.066s
== 100000 ==
original: 2.669s
new: 0.622s
If the results are not narrowed:
== 1 ==
original: 0.002s
new: 0.000s
== 10 ==
original: 0.002s
new: 0.001s
== 100 ==
original: 0.004s

original: 0.101s
new: 0.355s
== 100000 ==
original: 2.850s
new: 31.941s
So, unless 'git checkout <tab>' usually gives you more than 10000
results, you'll get an improvement :)
Other possible solutions perform better after 1000 words, but worst if
less than that:
COMPREPLY=($(awk -v cur="$3" -v pre="$2" -v suf="$4"
'$0 ~ cur { print pre$0suf }' <<< "$1" ))
COMPREPLY=($(printf -- "$2%s$4\n" $1 | grep "^$2$3"))

When setting up a "half-auth" repository in which reads can
be done anonymously but writes require authentication, it is
best if the server can require authentication for both the
ref advertisement and the actual receive-pack POSTs. This
alleviates the need for the admin to set http.receivepack in
the repositories, and means that the client is challenged
for credentials immediately, instead of partway through the
push process (and git clients older than v1.7.11.7 had
trouble handling these challenges).
Since detecting a push during the ref advertisement requires
matching the query string, and this is non-trivial to do in
Apache, we have traditionally punted and instructed users to
just protect "/git-receive-pack$". This patch provides the
mod_rewrite recipe to actually match the ref advertisement,
which is preferred.
While we're at it, let's add the recipe to our test scripts
so that we can be sure that it works, and doesn't get broken
(either by our changes or by changes in Apache).

line_log_data has held a diff_filespec* since the very early versions
of the code. However, the only place in the code where we actually
need the full filespec is parse_range_arg(); in all other cases, we
are only interested in the path, so there is hardly a reason to store
a filespec. Even worse, it causes a lot of redundant ->spec->path
pointer dereferencing.
And *even* worse, it caused the following bug. If you merge a rename
with a modification to the old filename, like so:
* Merge
| \
| * Modify foo
| |
* | Rename foo->bar
| /
* Create foo
we internally -- in process_ranges_merge_commit() -- scan all parents.
We are mainly looking for one that doesn't have any modifications, so
that we can assign all the blame to it and simplify away the merge.
In doing so, we run the normal machinery on all parents in a loop.
For each parent, we prepare a "working set" line_log_data by making a
copy with line_log_data_copy(), which does *not* make a copy of the
spec.
Now suppose the rename is the first parent. The diff machinery tells
us that the filepair is ('foo', 'bar'). We duly update the path we
are interested in:
rg->spec->path = xstrdup(pair->one->path);
But that 'struct spec' is shared between the output line_log_data and
the original input line_log_data. So we just wrecked the state of
process_ranges_merge_commit(). When we get around to the second
parent, the ranges tell us we are interested in a file 'foo' while the
commits touch 'bar'.
So most of this patch is just s/->spec->path/->path/ and associated
management changes. This implicitly fixes the bug because we removed
the shared parts between input and output of line_log_data_copy(); it
is now safe to overwrite the path in the copy.
There's one only somewhat related change: the comment in
process_all_files() explains the reasoning behind using 'range' there.
That bit of half-correct code had me sidetracked for a while.

Some callers, such as the git-annex web assistant, find it useful to
invoke git check-ignore as a persistent background process, which can
then have queries fed to its STDIN at any point, and the corresponding
response consumed from its STDOUT. For this we need to invoke
check_ignore() once per line of standard input, and flush standard
output after each result.
The above use case suggests that empty STDIN is actually a reasonable
scenario (e.g. when the caller doesn't know in advance whether any
queries need to be fed to the background process until after it's
already started), so we make the minor behavioural change that "no
pathspec given." is no longer emitted in when STDIN is empty.
Even though check_ignore() could now be changed to operate on a single
pathspec, we keep it operating on an array of pathspecs since that is
a more convenient way of consuming the existing pathspec API.

incrementally streamed to STDIN, and for each of these files, STDOUT
will indicate whether that file matched a pattern or not. (Without
this option, it would be impossible to tell whether the absence of

If a push fails because the remote-helper died (with fast-export),
the user may not see any error message. We do correctly die with a
failed exit code, as we notice that the helper has died while
reading back the ref status from the helper. However, we don't print
any message. This is OK if the helper itself printed a useful error
message, but we cannot count on that; let's let the user know that
the helper failed.
In the long run, it may make more sense to propagate the error back
up to push, so that it can present the usual status table and give a
nicer message. But this is a much simpler fix that can help
immediately.
While we're adding tests, let's also confirm that the remote-helper
dying is also detected when importing refs. We currently do so
robustly when the helper uses the "done" feature (and that is what
we test). We cannot do so reliably when the helper does not use the
"done" feature, but it is not even worth testing; the right solution
is for the helper to start using "done".

If we have a symlink "d" that points to a directory, we
should not be able to remove "d/f". In the normal case,
where "d/f" does not exist in the index, we already disallow
this, as we only remove things that git knows about in the
index. So for something like:
ln -s /outside/repo foo
git add foo
git rm foo/bar
we will properly produce an error (as there is no index
entry for foo/bar). However, if there is an index entry for
the path (e.g., because the movement is due to working tree
changes that have not yet been reflected in the index), we
will happily delete it, even though the path we delete from the
filesystem is not the same as the path in the index.
This patch documents that failure with a test.
While this is a bug, it should not be possible to cause
serious data loss with it. For any path that does not have
an index entry, we will complain and bail. For a path which
does have an index entry, we will do the usual up-to-date
content check. So even if the deleted path in the filesystem
is not the same as the one we are removing from the index,
we do know that they at least have the same content, and
that the content is included in HEAD.
That means the worst case is not the accidental loss of
content, but rather confusion by the user when a copy of a
file another part of the tree is removed. Which makes this
bug a minor and hard-to-trigger annoyance rather than a
data-loss bug (and hence the fix can be saved for a rainy
day when somebody feels like working on it).

If we used to have an index entry "d/f", but "d" has been
replaced by a non-directory entry, the user may still want
to run "git rm" to delete the stale index entry. They could
use "git rm --cached" to just touch the index, but "git rm"
should also work: we explicitly try to handle the case that
the file has already been removed from the working tree.
However, because unlinking "d/f" in this case will not yield
ENOENT, but rather ENOTDIR, we do not notice that the file
is already gone. Instead, we report it as an error.
The simple solution is to treat ENOTDIR in this case exactly
like ENOENT; all we want to know is whether the file is
already gone, and if a leading path is no longer a
directory, then by definition the sub-path is gone.

The loop that fills in the buffers that are later passed to the merge
driver exits early when not all stages of a path are present in the index.
But since the buffer pointers are not initialized in advance, the
subsequent accesses are undefined.
Initialize buffer pointers in advance to avoid undefined behavior later.
That is not sufficient, though, to get correct operation of handle_cache().
The function replays a conflicted merge to extract the part inside the
conflict markers. As written, the loop exits early when a stage is missing.
Consequently, the buffers for later stages that would be present in the
index are not filled in and the merge is replayed with incomplete data.
Fix it by investigating all stages of the given path.

The first thing filter-branch does is to create a temporary
directory, either ".git-rewrite" in the current directory
(which may be the working tree or the repository if bare),
or in a directory specified by "-d". We then chdir to
$tempdir/t as our temporary working directory in which to run
tree filters.
After finishing the filter, we then attempt to go back to
the original directory with "cd ../..". This works in the
.git-rewrite case, but if "-d" is used, we end up in a
random directory. The only thing we do after this chdir is
to run git-read-tree, but that means that:
1. The working directory is not updated to reflect the
filtered history.
2. We dump random files into "$tempdir/.." (e.g., if you
use "-d /tmp/foo", we dump junk into /tmp).
Fix it by recording the full path to the original directory
and returning there explicitly.

It's reasonably easy to see what is being tested, with the
exception that "testrepo" is a magic global name (it is
implicitly used in the helpers, but we have to name it
explicitly when calling git directly). Let's make it
explicit when call the helpers, too. This is slightly more

It also makes it easy for future tests to use an alternate

The output of "git submodule deinit sub" of a populated submodule prints
rm 'sub'
as the first line unless used with the -f option.
The "rm 'sub'" line is exactly the same output the user gets when using
"git rm sub" (because that command is used with the --dry-run option under
the hood to determine if the submodule is clean), which can easily lead to
the false impression that the submodule would be permanently removed. Also
users might be confused that the "rm 'submodule'" line won't show up when
the -f option is used, as the test is skipped in this case.
Silence the "rm 'submodule'" output by using the --quiet option for "git

If we manage to clone a remote repository but run into an
error in the checkout, it is probably sane to leave the repo
directory in place. That lets the user examine the situation
without spending time to re-clone from the remote (which may
be a lengthy process).
Rather than try to convert each die() from the checkout code
path into an error(), we simply set a flag that tells the
"remove_junk" atexit function to print a helpful message and
leave the repo in place.
Note that the test added in this patch actually passes
without the code change. The reason is that the cleanup code
is buggy; we chdir into the working tree for the checkout,
but still may use relative paths to remove the directories
(which means if you cloned into "foo", we would accidentally
remove "foo" from the working tree!). There's no point in
fixing it now, since this patch means we will never try to
remove anything after the chdir, anyway.

When 'git difftool --dir-diff' is using --no-symlinks (either explicitly
or implicitly because it's running on Windows), any working tree files
that have been copied to the temporary directory are copied back after
the difftool completes.
Because an earlier test uses "git add .", the "output" file used by
tests is tracked by Git and the following sequence occurs during some
tests:
1) the shell opens "output" to redirect the difftool output
2) difftool copies the empty "output" to the temporary directory
3) difftool runs "ls" which writes to "output"
4) difftool copies the empty "output" file back over the output of the
command
5) the output file doesn't contain the expected output, causing the
test to fail
Instead of adding all changes, explicitly add only the files that the
test is using, allowing later tests to write their result files into the
working tree.

After running the user's diff tool, git-difftool will copy any files
that differ between the working tree and the temporary tree. This is
useful when the user edits the file in their diff tool but is wrong if
they edit the working tree file while examining the diff.
Instead of copying unconditionally when the files differ, create and
index from the working tree files and only copy the temporary file back
if it was modified and the working tree file was not. If both files
have been modified, print a warning and exit with an error.
Note that we cannot use an existing index in git-difftool since those
contain the modified files that need to be checked out but here we are
looking at those files which are copied from the working tree and not
checked out. These are precisely the files which are not in the
existing indices.

The config-editing code used by "git config var value" is
built around the regular config callback parser, whose only
triggerable item is an actual key. As a result, it does not
know anything about section headers, which can result in
unnecessarily ugly output:
1. When we delete the last key in a section, we should be
able to delete the section header.
2. When we add a key into a section, we should be able to
reuse the same section header, even if that section did
not have any keys in it already.
Unfortunately, fixing these is not trivial with the current
code. It would involve the config parser recording and
passing back information on each item it finds, including
headers, keys, and even comments (or even better, generating
an actual in-memory parse-tree).
Since these behaviors do not cause any functional problems
(i.e., the resulting config parses as expected, it is just
uglier than one would like), fixing them can wait until
somebody feels like substantially refactoring the parsing
code. In the meantime, let's document them as known issues
with some tests.

allow "subdir/ export-ignore" to also exclude the directory, but
instead ended up _requiring_ the trailing slash by mistake.
A pattern "subdir" should match any path "subdir", whether it is a

git log -L:main:main.c
and it will dig up the main() function and show its line-log, provided
there are no other funcnames matching 'main'.

This is a rewrite of much of Bo's work, mainly in an effort to split
it into smaller, easier to understand routines.
The algorithm is built around the struct range_set, which encodes a
series of line ranges as intervals [a,b). This is used in two
contexts:
* A set of lines we are tracking (which will change as we dig through
history).
* To encode diffs, as pairs of ranges.
The main routine is range_set_map_across_diff(). It processes the
diff between a commit C and some parent P. It determines which diff
hunks are relevant to the ranges tracked in C, and computes the new
ranges for P.
The algorithm is then simply to process history in topological order
from newest to oldest, computing ranges and (partial) diffs. At
branch points, we need to merge the ranges we are watching. We will
find that many commits do not affect the chosen ranges, and mark them
TREESAME (in addition to those already filtered by pathspec limiting).
Another pass of history simplification then gets rid of such commits.
This is wired as an extra filtering pass in the log machinery. This
currently only reduces code duplication, but should allow for other
simplifications and options to be used.
Finally, we hook a diff printer into the output chain. Ideally we
would wire directly into the diff logic, to optionally use features
like word diff. However, that will require some major reworking of
the diff chain, so we completely replace the output with our own diff
for now.
As this was a GSoC project, and has quite some history by now, many
people have helped. In no particular order, thanks go to

We want to use the same style of -L n,m argument for 'git log -L' as
for git-blame. Refactor the argument parsing of the range arguments
from builtin/blame.c to the (new) file that will hold the 'git log -L'
logic.
To accommodate different data structures in blame and log -L, the file
contents are abstracted away; parse_range_arg takes a callback that it
uses to get the contents of a line of the (notional) file.
The new test is for a case that made me pause during debugging: the
'blame -L with invalid end' test was the only one that noticed an
outright failure to parse the end *at all*. So make a more explicit
test for that.

When we fetch from a remote, we do a revision walk to make
sure that what we received is connected to our existing
history. We do not do the same check for clone, which should
be able to check that we received an intact history graph.
The upside of this patch is that it will make clone more
resilient against propagating repository corruption. The
downside is that we will now traverse "rev-list --objects
--all" down to the roots, which may take some time (it is
especially noticeable for a "--local --bare" clone).
Note that we need to adjust t5710, which tries to make such
a bogus clone. Rather than checking after the fact that our
clone is bogus, we can simplify it to just make sure "git
clone" reports failure.

When clone is populating the working tree, it ignores the
return status from unpack_trees; this means we may report a
successful clone, even when the checkout fails.
When checkout fails, we may want to leave the $GIT_DIR in
place, as it might be possible to recover the data through
further use of "git checkout" (e.g., if the checkout failed
due to a transient error, disk full, etc). However, we
already die on a number of other checkout-related errors, so
this patch follows that pattern.
In addition to marking a now-passing test, we need to adjust
t5710, which blindly assumed it could make bogus clones of
very deep alternates hierarchies. By using "--bare", we can
avoid it actually touching any objects.

We try not to let corruption pass unnoticed over fetches and
clones. For the most part, this works, but there are some
broken corner cases, including:
1. We do not detect missing objects over git-aware
transports. This is a little hard to test, because the
sending side will actually complain about the missing
object.
To fool it, we corrupt a repository such that we have a
"misnamed" object: it claims to be sha1 X, but is
really Y. This lets the sender blindly transmit it, but
it is the receiver's responsibility to verify that what
it got is sane (and it does not).
2. We do not detect missing or misnamed blobs during the
checkout phase of clone.

When we are streaming an index blob to disk, we store the
error from stream_blob_to_fd in the "result" variable, and
then immediately overwrite that with the return value of
"close". That means we catch errors on close (e.g., problems
committing the file to disk), but miss anything which
happened before then.
We can fix this by using bitwise-OR to accumulate errors in
our result variable.
While we're here, we can also simplify the error handling
with an early return, which makes it easier to see under
which circumstances we need to clean up.

Teach "diff --cc" output to honor options to ignore various forms
of whitespace changes.
* ap/combine-diff-ignore-whitespace:
Allow combined diff to ignore white-spaces
In checkout_paths() we do this
- for all updated items, call match_pathspec
- for all items, call match_pathspec (inside unmerge_cache)
- for all items, call match_pathspec (for showing "path .. is unmerged)
- for updated items, call match_pathspec and update paths
That's a lot of duplicate match_pathspec(s) and the function is not
exactly cheap to be called so many times, especially on large indexes.
This patch makes it call match_pathspec once per updated index entry,
save the result in ce_flags and reuse the results in the following
loops.
The changes in 0a1283b (checkout $tree $path: do not clobber local
changes in $path not in $tree - 2011-09-30) limit the affected paths
to ones we read from $tree. We do not do anything to other modified
entries in this case, so the "for all items" above could be modified
to "for all updated items". But..
The command's behavior now is modified slightly: unmerged entries that
match $path, but not updated by $tree, are now NOT touched. Although
this should be considered a bug fix, not a regression. A new test is
added for this change.
And while at there, free ps_matched after use.
The following command is tested on webkit, 215k entries. The pattern
is chosen mainly to make match_pathspec sweat:

Logic in still_interesting function allows to stop the commits
traversing if the oldest processed commit is not older then the
youngest commit on the list to process and the list contains only
commits marked as not interesting ones. It can be premature when dealing
with a set of coequal commits. For example git rev-list A^! --not B
provides wrong answer if all commits in the range A..B had the same

Originally update-pre-post-images could assume that any whitespace
fixing will make the result only shorter by unexpanding runs of
leading SPs into HTs and removing trailing whitespaces at the end of
lines. Updating the post-image we read from the patch to match the
actual result can be performed in-place under this assumption.
These days, however, we have tab-in-indent (aka Python) rule whose
result can be longer than the original, and we do need to allocate
a larger buffer than the input and replace the result.
Fortunately the support for lengthening rewrite was already added
when we began supporting "match while ignoring whitespace
differences" mode in 86c91f9179 (git apply: option to ignore
whitespace differences, 2009-08-04). We only need to correctly
count the number of bytes necessary to hold the updated result and

Some test scripts use the GIT_TRACE mechanism to dump
debugging information to descriptor 3 (and point it to a
file using the shell). On Windows, however, bash is unable
to set up descriptor 3. We do not write our trace to the
file, and worse, we may interfere with other operations
happening on descriptor 3, causing tests to fail or even
behave inconsistently.
Prior to commit 97a83fa (upload-pack: remove packet debugging
harness), these tests used GIT_DEBUG_SEND_PACK, which only
supported output to a descriptor. The tests in t5503 were
always broken on Windows, and were marked to be skipped via
the NOT_MINGW prerequisite. In t5700, the tests used to pass
prior to 97a83fa, but only because they were not careful
enough; because we only grepped the trace file, an empty
file looked successful to us. But post-97a83fa, the writing
to descriptor 3 causes "git fetch" to hang (presumably
because we are throwing random bytes into the middle of the
protocol).
Now that we are using the GIT_TRACE mechanism, we can
improve both scripts by asking git to write directly to a
file rather than a descriptor. That fixes the hang in t5700,
and should allow t5503 to successfully run on Windows.
In both cases we now also use "test -s" to double-check that
our trace file actually contains output, which should reduce
the possibility of an erroneously passing test.

Older versions of pack-refs did not write peel lines for
refs outside of refs/tags. This meant that on reading the
pack-refs file, we might set the REF_KNOWS_PEELED flag for
such a ref, even though we do not know anything about its
peeled value.
The previous commit updated the writer to always peel, no
matter what the ref is. That means that packed-refs files
written by newer versions of git are fine to be read by both
old and new versions of git. However, we still have the
problem of reading packed-refs files written by older
versions of git, or by other implementations which have not
yet learned the same trick.
The simplest fix would be to always unset the
REF_KNOWS_PEELED flag for refs outside of refs/tags that do
not have a peel line (if it has a peel line, we know it is
valid, but we cannot assume a missing peel line means
anything). But that loses an important optimization, as
upload-pack should not need to load the object pointed to by
refs/heads/foo to determine that it is not a tag.
Instead, we add a "fully-peeled" trait to the packed-refs
file. If it is set, we know that we can trust a missing peel
line to mean that a ref cannot be peeled. Otherwise, we fall

When we pack an annotated tag ref, we write not only the
sha1 of the tag object along with the ref, but also the sha1
obtained by peeling the tag. This lets readers of the
pack-refs file know the peeled value without having to
actually load the object, speeding up upload-pack's ref
advertisement.
The writer marks a packed-refs file with peeled refs using
the "peeled" trait at the top of the file. When the reader
sees this trait, it knows that each ref is either followed
by its peeled value, or it is not an annotated tag.
However, there is a mismatch between the assumptions of the
reader and writer. The writer will only peel refs under
refs/tags, but the reader does not know this; it will assume
a ref without a peeled value must not be a tag object. Thus
an annotated tag object placed outside of the refs/tags
hierarchy will not have its peeled value printed by
upload-pack.
The simplest way to fix this is to start writing peel values
for all refs. This matches what the reader expects for both
new and old versions of git.

git pull passed -q and -v only to git merge, but they can be useful for
git rebase as well, so pass them there, too.
In particular, using -q shuts up the "Already up-to-date." message.
Especially, a new test script runs the same "pull --rebase" twice to
make sure both cases are quiet, when it has something to fetch and
when it is already up to date.

When upload-pack receives a "want" line from the client, it
adds it to an object array. We call lookup_object to find
the actual object, which will only check for objects already
in memory. This works because we are expecting to find
objects that we already loaded during the ref advertisement.
We use the resulting object structs for a variety of
purposes. Some of them care only about the object flags, but
others care about the type of the object (e.g.,
ok_to_give_up), or even feed them to the revision parser
(when --depth is used), which assumes that objects it
receives are fully parsed.
Once upon a time, this was OK; any object we loaded into
memory would also have been parsed. But since 435c833
(upload-pack: use peel_ref for ref advertisements,
2012-10-04), we try to avoid parsing objects during the ref
advertisement. This means that lookup_object may return an
object with a type of OBJ_NONE. The resulting mess depends
on the exact set of objects, but can include the revision
parser barfing, or the shallow code sending the wrong set of
objects.
This patch teaches upload-pack to parse each "want" object
as we receive it. We do not replace the lookup_object call
with parse_object, as the current code is careful not to let
just any object appear on a "want" line, but rather only one
we have previously advertised (whereas parse_object would
actually load any arbitrary object from disk).

This prints more helpful info when HEAD is detached: is it detached

When a remote ref or a tag is checked out, HEAD is automatically
detached. There is no user-friendly way to find out what ref is
checked out in this case. This patch digs in reflog for this
information and shows "HEAD detached from origin/master" or "HEAD
detached at v1.8.0" instead of "currently not on any branch".
When it cannot figure out the original ref, it shows an abbreviated
SHA-1. "Currently not on any branch" would never display (unless
reflog is pruned to near empty that the last checkout entry is lost).

When looking up the stream filter, write_entry() should be passing the
path of the file in the repository, not the path to which the content is
going to be written. This allows the file to be correctly looked up
against the .gitattributes files in the working tree.
This change makes the streaming case match the non-streaming case which
passes ce->name to convert_to_working_tree later in the same function.
The two tests added here test the different paths through write_entry
since the CRLF filter is a streaming filter but the user-defined smudge
filter is not streamed.

The combined diff --cc output does not honor options to ignore
whitespace changes (-b, -w, and --ignore-space-at-eol).
Correct this by passing diff flags to diff engine, so that combined
diff behaves as normal diff does with spaces, and by coalescing
lines that are removed from both (or more) parents, honoring the
same rule to ignore whitespace changes.

Some users like to edit files in their diff tool when using "git
difftool --dir-diff --symlink" to compare against the working tree but
difftool currently only created symlinks when a file contains unstaged
changes.
Change this behaviour so that symlinks are created whenever the
right-hand side of the comparison has the same SHA1 as the file in the
working tree.
Note that textconv filters are handled in the same way as by git-diff
and if a clean filter is not the inverse of its smudge filter we already
get a null SHA1 from "diff --raw" and will symlink the file without
going through the new hash-object based check.

The generic chdir() helper sets the PWD environment
variable, as that is what is used by p4 to know its
current working directory. Normally the shell would
do this, but in git-p4, we must do it by hand.
However, when the path contains a symbolic link,
os.getcwd() will return the physical location. If the
p4 client specification includes symlinks, setting PWD
to the physical location causes p4 to think it is not
inside the client workspace. It complains, e.g.
Path /vol/bar/projects/foo/... is not under client root /p/foo
One workaround is to use AltRoots in the p4 client specification,
but it is cleaner to handle it directly in git-p4.
Other uses of chdir still require setting PWD to an
absolute path so p4 features like P4CONFIG work. See
bf1d68f (git-p4: use absolute directory for PWD env
var, 2011-12-09).

git-archive relies on get_pathspec to convert its argv into
a list of pathspecs. When get_pathspec is given an empty
argv list, it returns a single pathspec, the empty string,
to indicate that everything matches. When we feed this to
our path_exists function, we typically see that the pathspec
turns up at least one item in the tree, and we are happy.
But when our tree is empty, we erroneously think it is
because the pathspec is too limited, when in fact it is
simply that there is nothing to be found in the tree. This
is a weird corner case, but the correct behavior is almost
certainly to produce an empty archive, not to exit with an
error.
This patch teaches git-archive to create empty archives when
there is no pathspec given (we continue to complain if a
pathspec is given, since it obviously is not matched). It
also confirms that the tar and zip writers produce sane
output in this instance.

Even though an earlier attempt (bafc478..41dd00bad) cleaned
up RFC 2047 encoding, pretty.c::add_rfc2047() still decides
where to split the output line by going through the input
one byte at a time, and potentially splits a character in
the middle. A subject line may end up showing like this:
".... fö?? bar". (instead of ".... föö bar".)
if split incorrectly.
RFC 2047, section 5 (3) explicitly forbids such beaviour
Each 'encoded-word' MUST represent an integral number of
characters. A multi-octet character may not be split across
adjacent 'encoded- word's.
that means that e.g. for
Subject: .... föö bar
encoding
Subject: =?UTF-8?q?....=20f=C3=B6=C3=B6?=
=?UTF-8?q?=20bar?=
is correct, and
Subject: =?UTF-8?q?....=20f=C3=B6=C3?= <-- NOTE ö is broken here
=?UTF-8?q?=B6=20bar?=
is not, because "ö" character UTF-8 encoding C3 B6 is split here across
adjacent encoded words.
To fix the problem, make the loop grab one _character_ at a time and
determine its output length to see where to break the output line. Note
that this version only knows about UTF-8, but the logic to grab one
character is abstracted out in mbs_chrlen() function to make it possible
to extend it to other encodings with the help of iconv in the future.

When "git add subdir/" is run without "-u" or "-A" option, e.g.
$ edit subdir/x
$ create subdir/y
$ rm subdir/z
$ git add subdir/
the command does not notice removal of paths (e.g. subdir/z) from
the working tree. This sometimes confuses new people, as arguably
"git add" is told to record the current state of "subdir/" as a
whole, not the current state of the paths that exist in the working
tree that matches that pathspec (the latter by definition excludes
the state of "subdir/z" because it does not exist in the working
tree).
Plan to eventually make "git add" pretend as if "-A" is given when
there is a pathspec on the command line. When resolving a conflict
to remove a path, the current code tells you to "git rm $path", but
with such a change, you will be able to say "git add $path" (of
course you can do "git add -A $path" today). That means that we can
simplify the advice messages given by "git status". That all will
be in Git 2.0 or later, if we are going to do so.
For that transition to work, people need to learn either to say "git
add --no-all subdir/" when they want to ignore the removed paths
like "subdir/z", or to say "git add -A subdir/" when they want to
take the state of the directory as a whole.
"git add" without any argument will continue to be a no-op.

If an explicit GIT_DIR is given without a working tree, we
implicitly assume that the current working directory should
be used as the working tree. E.g.,:
GIT_DIR=/some/repo.git git status
would compare against the cwd.
Unfortunately, we fool this rule for sub-invocations of git
by setting GIT_DIR internally ourselves. For example:
git init foo
cd foo/.git
git status ;# fails, as we expect
git config alias.st status
git status ;# does not fail, but should
What happens is that we run setup_git_directory when doing
alias lookup (since we need to see the config), set GIT_DIR
as a result, and then leave GIT_WORK_TREE blank (because we
do not have one). Then when we actually run the status
command, we do setup_git_directory again, which sees our
explicit GIT_DIR and uses the cwd as an implicit worktree.
It's tempting to argue that we should be suppressing that
second invocation of setup_git_directory, as it could use
the values we already found in memory. However, the problem
still exists for sub-processes (e.g., if "git status" were
an external command).
You can see another example with the "--bare" option, which
sets GIT_DIR explicitly. For example:
git init foo
cd foo/.git
git status ;# fails
git --bare status ;# does NOT fail
We need some way of telling sub-processes "even though
GIT_DIR is set, do not use cwd as an implicit working tree".
We could do it by putting a special token into
GIT_WORK_TREE, but the obvious choice (an empty string) has
some portability problems.
Instead, we add a new boolean variable, GIT_IMPLICIT_WORK_TREE,
which suppresses the use of cwd as a working tree when
GIT_DIR is set. We trigger the new variable when we know we
are in a bare setting.
The variable is left intentionally undocumented, as this is
an internal detail (for now, anyway). If somebody comes up
with a good alternate use for it, and once we are confident
we have shaken any bugs out of it, we can consider promoting
it further.

With "git submodule init" the user is able to tell git he cares about one
or more submodules and wants to have it populated on the next call to "git
submodule update". But currently there is no easy way he could tell git he
does not care about a submodule anymore and wants to get rid of his local
work tree (except he knows a lot about submodule internals and removes the
"submodule.$name.url" setting from .git/config together with the work tree
himself).
Help those users by providing a 'deinit' command. This removes the
whole submodule.<name> section from .git/config (either for the given
submodule(s) or for all those which have been initialized if '.' is used)
together with their work tree. Fail if the current work tree contains
modifications (unless forced), but don't complain when either the work
tree is already removed or no settings are found in .git/config.
Add tests and link the man pages of "git submodule deinit" and "git rm"
to assist the user in deciding whether removing or unregistering the
submodule is the right thing to do for him. Also add the deinit subcommand

Before 82dce99 (attr: more matching optimizations from .gitignore,
2012-10-15), .gitattributes did not have any special treatment of a
leading '!'. The docs, however, always said
The rules how the pattern matches paths are the same as in
`.gitignore` files; see linkgit:gitignore[5].
By those rules, leading '!' means pattern negation. So 82dce99
correctly determined that this kind of line makes no sense and should
be disallowed.
However, users who actually had a rule for files starting with a '!'
are in a bad position: before 82dce99 '!' matched that literal
character, so it is conceivable that users have .gitattributes with
such lines in them. After 82dce99 the unescaped version was
disallowed in such a way that git outright refuses to run(!) most
commands in the presence of such a .gitattributes. It therefore
becomes very hard to fix, let alone work with, such repositories.
Let's at least allow the users to fix their repos: change the fatal

With core.ignorecase=true, name-hash.c builds a case insensitive index of
all tracked directories. Currently, the existing cache entry structures are
added multiple times to the same hashtable (with different name lengths and
hash codes). However, there's only one dir_next pointer, which gets
completely messed up in case of hash collisions. In the worst case, this
causes an endless loop if ce == ce->dir_next (see t7062).
Use a separate hashtable and separate structures for the directory index
so that each directory entry has its own next pointer. Use reference
counting to track which directory entry contains files.
There are only slight changes to the name-hash.c API:
- new free_name_hash() used by read_cache.c::discard_index()
- remove_name_hash() takes an additional index_state parameter
- index_name_exists() for a directory (trailing '/') may return a cache
entry that has been removed (CE_UNHASHED). This is not a problem as the
return value is only used to check if the directory exists (dir.c) or to
normalize casing of directory names (read-cache.c).
Getting rid of cache_entry.dir_next reduces memory consumption, especially
with core.ignorecase=false (which doesn't use that member at all).
With core.ignorecase=true, building the directory index is slightly faster
as we add / check the parent directory first (instead of going through all
directory levels for each file in the index). E.g. with WebKit (~200k
files, ~7k dirs), time spent in lazy_init_name_hash is reduced from 176ms
to 130ms.

Currently ZIP archive entries of files with export-subst attribute are
broken if they are stored uncompressed.
We get the size of a file from sha1_object_info(), but this number is
likely wrong for files whose contents are changed due to export-subst
placeholder expansion. We use sha1_file_to_archive() to get the
expanded file contents and size in that case. We proceed to use that
size for the uncompressed size field (good), but the compressed size
field is set based on the size from sha1_object_info() (bad).
This matters only for uncompressed files because for deflated files
we use the correct value after compression is done. And for files
without export-subst expansion the sizes from sha1_object_info() and
sha1_file_to_archive() are the same, so they are unaffected as well.
This patch fixes the issue by setting the compressed size based on the
uncompressed size only after we actually know the latter.
Also make use of the test file substfile1 to check for the breakage;
it was only stored verbatim so far. For that purpose, set the
attribute export-subst and replace its contents with the expected
expansion after committing.

Commit 1b77d83cab 'setup_git_directory_gently_1(): resolve symlinks
in ceiling paths' changed the setup code to resolve symlinks in the
entries in GIT_CEILING_DIRECTORIES. Because those entries are
compared textually to the symlink-resolved current directory, an
entry in GIT_CEILING_DIRECTORIES that contained a symlink would have
no effect. It was known that this could cause performance problems
if the symlink resolution *itself* touched slow filesystems, but it
was thought that such use cases would be unlikely. The intention of
the earlier change was to deal with a case when the user has this:
GIT_CEILING_DIRECTORIES=/home/gitster
but in reality, /home/gitster is a symbolic link to somewhere else,
e.g. /net/machine/home4/gitster. A textual comparison between the
specified value /home/gitster and the location getcwd(3) returns
would not help us, but readlink("/home/gitster") would still be
fast.
After this change was released, Anders Kaseorg <andersk@mit.edu>
reported:

To allow users to work around this problem, give them a mechanism to
turn off symlink resolution in GIT_CEILING_DIRECTORIES entries. All
the entries that follow an empty entry will not be checked for symbolic
links and used literally in comparison. E.g. with these:
GIT_CEILING_DIRECTORIES=:/foo/bar:/xyzzy or
GIT_CEILING_DIRECTORIES=/foo/bar::/xyzzy
we will not readlink("/xyzzy") because it comes after an empty entry.
With the former (but not with the latter), "/foo/bar" comes after an

are not dependent on the success of the previous test.
The end result is shorter tests and better test isolation.

If you set the GIT_DEBUG_SEND_PACK environment variable,
upload-pack will dump lines it receives in the receive_needs
phase to a descriptor. This debugging harness is a strict
subset of what GIT_TRACE_PACKET can do. Let's just drop it
in favor of that.
A few tests used GIT_DEBUG_SEND_PACK to confirm which
objects get sent; we have to adapt them to the new output
format.

Usually we do not pass an empty string to the function hash_name()
because we almost always ask for hash values for a path that is a
candidate to be added to the index. However, check-ignore (and most
likely check-attr, but I didn't check) apparently has a callchain
to ask the hash value for an empty path when it was given a "." from
the top-level directory to ask "Is the path . excluded by default?"
Make sure that hash_name() does not overrun the end of the given
pathname even when it is empty.
Remove a sweep-the-issue-under-the-rug conditional in check-ignore
that avoided to pass an empty string to the callchain while at it.
It is a valid question to ask for check-ignore if the top-level is
set to be ignored by default, even though the answer is most likely
no, if only because there is currently no way to specify such an
entry in the .gitignore file. But it is an unusual thing to ask and
it is not worth optimizing for it by special casing at the top level
of the call chain.

test_expect_success_multi() helper function warrants some explanation,
since at first sight it may seem like generic test framework plumbing,
but is in fact specific to testing check-ignore, and allows more
thorough testing of the various output formats without significantly
increase the size of t0008.

Currently, git will append two newlines to every message supplied via
the -m switch. The purpose of this is to allow -m to be supplied
multiple times and have each supplied string become a paragraph in the
resulting commit message.
Normally, this does not cause a problem since any trailing newlines will
be removed by the cleanup operation. If cleanup=verbatim for example,
then the trailing newlines will not be removed and will survive into the
resulting commit message.
Instead, let's ensure that the string supplied to -m is newline terminated,
but only append a second newline when appending additional messages.
Fixes the test in t7502.

This test attempts to verify that a commit message supplied to 'git
commit' via the -m switch was used in full as the commit message for a
commit when --cleanup=verbatim was used.
But, this test has been broken since it was introduced. Since the
commit message containing trailing newlines was supplied to 'git commit'
using a command substitution, the trailing newlines were removed by the
shell. This means that a string without any trailing newlines was
actually supplied to 'git commit'.
The test was able to complete successfully since internally, git appends
two newlines to each string supplied via the -m switch. So, the two
newlines removed by the shell were then re-added by git, and the
resulting commit matched what was expected.
So, let's move the initial creation of the commit message string out
from within a previous test so that it stands alone. Assign the desired
commit message to a variable using literal newlines. Then populate the
expect file from the contents of the commit message variable. This way
the shell variable becomes the authoritative source of the commit
message and can be supplied via the -m switch with the trailing newlines
intact.
Mark this test as failing, since it is not handled correctly by git.
As described above, git appends two extra newlines to every string
supplied via -m, even to the ones that already end with a newline.

This test attempts to verify that a commit in "verbatim" mode, when
supplied a commit template, produces a commit in which the commit
message matches exactly the template that was supplied. But, since the
commit operation appends additional instructions for the user as
comments in the commit buffer, which would cause the comparison to fail,
this test decided to compare only the first three lines (the length of
the template) of the resulting commit message to the original template
file.
This has two problems.
1. It does not allow the template to be lengthened or shortened
without also modifying the number of lines that are considered
significant (i.e. the argument to 'head -n').
2. It will not catch a bug in git that causes git to append additional
lines to the commit message.
So, let's use the --no-status option to 'git commit' which will cause
git to refrain from appending the lines of instructional text to the
commit message. This will allow the entire resulting commit message to
be compared against the expected value.

prepare_packed_git_one() is modified to allow count-objects to hook a
report function to so we don't need to duplicate the pack searching
logic in count-objects.c. When report_pack_garbage is NULL, the
overhead is insignificant.
The garbage is reported with warning() instead of error() in packed
garbage case because it's not an error to have garbage. Loose garbage
is still reported as errors and will be converted to warnings later.
