When running a command like:

the date option was ignored. This patch causes it to use whatever
format was specified by --date (or by --relative-date, etc), just

4f38f6b5ba diff*: fix worktree setup
This fixes "git diff", "git diff-files" and "git diff-index" to work
correctly under worktree setup. Because diff* family works in many modes
and not all of them require worktree, Junio made a nice summary
(with a little modification from me):

 * diff-files is about comparing with work tree, so it obviously needs a
  work tree;

 * diff-index also does, except "diff-index --cached" or "diff --cached TREE"

 * no-index is about random files outside git context, so it obviously
   doesn't need any work tree;

 * comparing two (or more) trees doesn't;

 * comparing two blobs doesn't;

 * comparing a blob with a random file doesn't;

2b84373219 Suppress some bash redirection error messages
In particular, when testing if the filesystem allows tabs in
filenames, bash issues an error something like:

./t4016-diff-quote.sh: pathname	with HT: No such file or directory

which is caused by the failure of the (stdout) redirection,
since the file cannot be created. In order to suppress the
error message, you must redirect stderr to /dev/null, *before*
the stdout redirection on the command-line.

Also, remove a redundant filesystem check from the begining of
the t3902-quoted.sh test and standardise the "test skipped"
message to 'say' on exit.

0843acfd2c Fix "git log -i --grep"
This has been broken in v1.6.0 due to the reorganization of
the revision option parsing code. The "-i" is completely
ignored, but works fine in "git log --grep -i".

What happens is that the code for "-i" looks for
revs->grep_filter; if it is NULL, we do nothing, since there
are no grep filters. But that is obviously not correct,
since we want it to influence the later --grep option. Doing
it the other way around works, since "-i" just impacts the
existing grep_filter option.

Instead, we now always initialize the grep_filter member and
just fill in options and patterns as we get them. This means
that we can no longer check grep_filter for NULL, but
instead must check the pattern list to see if we have any
actual patterns.

446247db78 merge: fix numerus bugs around "trivial merge" area
The "trivial merge" codepath wants to optimize itself by making an
internal call to the read-tree machinery, but it does not read the index
before doing so, and the codepath is never exercised.  Incidentally, this
failure to read the index upfront means that the safety to refuse doing
anything when the index is unmerged does not kick in, either.

These two problem are fixed by using read_cache_unmerged() that does read
the index before checking if it is unmerged at the beginning of
cmd_merge().

The primary logic of the merge, however, assumes that the process never
reads the index in-core, and the call to write_cache_as_tree() it makes
from write_tree_trivial() will always read from the on-disk index that is
prepared the strategy back-ends.  This assumption is now broken by the
above fix.  To fix this issue, we now call discard_cache() before calling
write_tree_trivial() when it wants to write the on-disk index as a tree.

When multiple strategies are tried, their results are evaluated by reading
the resulting index and inspecting it.  The codepath needs to make a call
to read_cache() for each successful strategy, and for that to work, they
need to discard_cache() the one read by the previous round.

Also the "trivial merge" forgot that the current commit is one of the
parents of the resulting commit.

c35539eb10 diff --check: do not get confused by new blank lines in the middle
The code remembered that the last diff output it saw was an empty line,
and tried to reset that state whenever it sees a context line, a non-blank
new line, or a new hunk.  However, this codepath asks the underlying diff
engine to feed diff without any context, and the "just saw an empty line"
state was not reset if you added a new blank line in the last hunk of your
patch, even if it is not the last line of the file.

e9d7d10a7f mailinfo: avoid violating strbuf assertion
In handle_from, we calculate the end boundary of a section
to remove from a strbuf using strcspn like this:

  el = strcspn(buf, set_of_end_boundaries);
  strbuf_remove(&sb, start, el + 1);

This works fine if "el" is the offset of the boundary
character, meaning we remove up to and including that
character. But if the end boundary didn't match (that is, we
hit the end of the string as the boundary instead) then we
want just "el". Asking for "el+1" caught an out-of-bounds
assertion in the strbuf library.

This manifested itself when we got a 'From' header that had
just an email address with nothing else in it (the end of
the string was the end of the address, rather than, e.g., a
trailing '>' character), causing git-mailinfo to barf.

289796dd29 mailinfo: re-fix MIME multipart boundary parsing
Recent changes to is_multipart_boundary() caused git-mailinfo to segfault.
The reason was after handling the end of the boundary the code tried to look
for another boundary.  Because the boundary list was empty, dereferencing
the pointer to the top of the boundary caused the program to go boom.

The fix is to check to see if the list is empty and if so go on its merry
way instead of looking for another boundary.

I also fixed a couple of increments and decrements that didn't look correct
relating to content_top.

The boundary test case was updated to catch future problems like this again.

21926fe885 t5304-prune: adjust file mtime based on system time rather than file mtime
test-chmtime can adjust the mtime of a file based on the file's mtime, or
based on the system time. For files accessed over NFS, the file's mtime is
set by the NFS server, and as such may vary a great deal from the NFS
client's system time if the clocks of the client and server are out of
sync. Since these tests are testing the expire feature of git-prune, an
incorrect mtime could cause a file to be expired or not expired incorrectly
and produce a test failure.

Avoid this NFS pitfall by modifying the calls to test-chmtime so that the
mtime is adjusted based on the system time, rather than the file's mtime.

6d6f9cddbe pack-objects: Allow missing base objects when creating thin packs
If we are building a thin pack and one of the base objects we would
consider for deltification is missing its OK, the other side already
has that base object.  We may be able to get a delta from another
object, or we can simply send the new object whole (no delta).

This change allows a shallow clone to store only the objects which
are unique to it, as well as the boundary commit and its trees, but
avoids storing the boundary blobs.  This special form of a shallow
clone is able to represent just the difference between two trees.

Pack objects change suggested by Nicolas Pitre.

a9fd1383a7 mailinfo: fix MIME multi-part message boundary handling
After finding a MIME multi-part message boundary line, the handle_body()
function is supposed to first flush any accumulated contents from the
previous part to the output stream.  However, the code mistakenly output
the boundary line it found.

The old code that used one global, fixed-length buffer line[] used an
alternate static buffer newline[] for keeping track of this accumulated
contents and flushed newline[] upon seeing the boundary; when 3b6121f
(git-mailinfo: use strbuf's instead of fixed buffers, 2008-07-13)
converted a fixed-length buffer in this program to use strbuf,these two
buffers were converted to "line" and "prev" (the latter of which now has a
much more sensible name) strbufs, but the code mistakenly flushed "line"
(which contains the boundary we have just found), instead of "prev".

This resulted in the first boundary to be output in front of the first
line of the message.

The rewritten implementation of handle_boundary() lost the terminating
newline; this would then result in the second line of the message to be
stuck with the first line.

The is_multipart_boundary() was designed to catch both the internal
boundary and the terminating one (the one with trailing "--"); this also
was broken with the rewrite, and the code in the handle_boundary() to
handle the terminating boundary was never triggered.

570d35c26d git-svn: Allow deep branch names by supporting multi-globs
Some repositories use a deep branching strategy, such as:

    branches/1.0/1.0.rc1
    branches/1.0/1.0.rc2
    branches/1.0/1.0.rtm
    branches/1.0/1.0.gold

Only allowing a single glob stiffles this.

This change allows for a single glob 'set' to accept this deep
branching strategy.

The ref glob depth must match the branch glob depth.  When using
the -b or -t options for init or clone, this is automatically
done.

For example, using the above branches:

  svn-remote.svn.branches = branches/*/*:refs/remote/*/*

gives the following branch names:

  1.0/1.0.rc1
  1.0/1.0.rc2
  1.0/1.0.rtm
  1.0/1.0.gold

dbd0f5c769 Files given on the command line are relative to $cwd
When running "git commit -F file" and "git tag -F file" from a
subdirectory, we should take it as relative to the directory we started
from, not relative to the top-level directory.

This adds a helper function "parse_options_fix_filename()" to make it more
convenient to fix this class of issues.  Ideally, parse_options() should
support a new type of option, "OPT_FILENAME", to do this uniformly, but
this patch is meant to go to 'maint' to fix it minimally.

One thing to note is that value for "commit template file" that comes from
the command line is taken as relative to $cwd just like other parameters,
but when it comes from the configuration varilable 'commit.template', it
is taken as relative to the working tree root as before.  I think this
difference actually is sensible (not that I particularly think
commit.template itself is sensible).

indegree is now incremented by 1 in the cases where the commit used
to have the TOPOSORT flag.

This is the same behavior as before, since indegree could not be
non-zero when TOPOSORT was unset.

Incidentally, this fixes the bug in show-branch where the 8th column
was not shown: show-branch sorts the commits in topological order,
assuming that all the commit flags are available for show-branch's
private matters.

But this was not true: TOPOSORT was identical to the flag corresponding
to the 8th ref.  So the flags for the 8th column were unset by the
topological sorting.

b2a5627651 make sure parsed wildcard refspec ends with slash
A wildcard refspec is internally parsed into a refspec structure with src
and dst strings.  Many parts of the code assumed that these do not include
the trailing "/*" when matching the wildcard pattern with an actual ref we
see at the remote.  What this meant was that we needed to make sure not
just that the prefix matched, and also that a slash followed the part that
matched.

But a codepath that scans the result from ls-remote and finds matching
refs forgot to check the "matching part must be followed by a slash" rule.
This resulted in "refs/heads/b1" from the remote side to mistakenly match
the source side of "refs/heads/b/*:refs/remotes/b/*" refspec.

Worse, the refspec crafted internally by "git-clone", and a hardcoded
preparsed refspec that is used to implement "git-fetch --tags", violated
this "parsed widcard refspec does not end with slash" rule; simply adding
the "matching part must be followed by a slash" rule then would have
broken codepaths that use these refspecs.

This commit changes the rule to require a trailing slash to parsed
wildcard refspecs.  IOW, "refs/heads/b/*:refs/remotes/b/*" is parsed as
src = "refs/heads/b/" and dst = "refs/remotes/b/".  This allows us to
simplify the matching logic because we only need to do a prefixcmp() to
notice "refs/heads/b/one" matches and "refs/heads/b1" does not.

6b2fbaaffc format-patch: Produce better output with --inline or --attach
This patch makes two small changes to improve the output of --inline
and --attach.

The first is to write a newline preceding the boundary. This is needed because
MIME defines the encapsulation boundary as including the preceding CRLF (or in
this case, just LF), so we should be writing one. Without this, the last
newline in the pre-diff content is consumed instead.

The second change is to always write the line termination character
(default: newline) even when using --inline or --attach. This is simply to
improve the aesthetics of the resulting message. When using --inline an email
client should render the resulting message identically to the non-inline
version. And when using --attach this adds a blank line preceding the
attachment in the email, which is visually attractive.

81dc2307d0 git-mv: Keep moved index entries inact
The rewrite of git-mv from a shell script to a builtin was perhaps
a little too straightforward: the git add and git rm queues were
emulated directly, which resulted in a rather complicated code and
caused an inconsistent behaviour when moving dirty index entries;
git mv would update the entry based on working tree state,
except in case of overwrites, where the new entry would still have
sha1 of the old file.

This patch introduces rename_index_entry_at() into the index toolkit,
which will rename an entry while removing any entries the new entry
might render duplicate. This is then used in git mv instead
of all the file queues, resulting in a major simplification
of the code and an inevitable change in git mv -n output format.

Also the code used to refuse renaming overwriting symlink with a regular
file and vice versa; there is no need for that.

A few new tests have been added to the testsuite to reflect this change.

859fdabaed git-checkout: improve error messages, detect ambiguities.
The patch is twofold: it moves the option consistency checks just under
the parse_options call so that it doesn't get in the way of the tree
reference vs. pathspecs desambiguation.

The other part rewrites the way to understand arguments so that when
git-checkout fails it does with an understandable message. Compared to the
previous behavior we now have:

  - a better error message when doing:

        git checkout <blob reference> --

    now complains about the reference not pointing to a tree, instead of
    things like:

        error: pathspec <blob reference> did not match any file(s) known to git.
        error: pathspec '--' did not match any file(s) known to git.

  - a better error message when doing:

        git checkout <path> --

    It now complains about <path> not being a reference instead of the
    completely obscure:

        error: pathspec '--' did not match any file(s) known to git.

  - an error when -- wasn't used, and the first argument is ambiguous
    (i.e. can be interpreted as both ref and as path).

sorting, but we can just as well use the member "indegree" for it:
indegree is now incremented by 1 in the cases where the commit used

This is the same behavior as before, since indegree could not be

Incidentally, this fixes the bug in show-branch where the 8th column
was not shown: show-branch sorts the commits in topological order,
assuming that all the commit flags are available for show-branch's
private matters.

But this was not true: TOPOSORT was identical to the flag corresponding
to the 8th ref.  So the flags for the 8th column were unset by the
topological sorting.

d14e7407b3 "needs update" considered harmful
"git update-index --refresh", "git reset" and "git add --refresh" have
reported paths that have local modifications as "needs update" since the
beginning of git.

Although this is logically correct in that you need to update the index at
that path before you can commit that change, it is now becoming more and
more clear, especially with the continuous push for user friendliness
since 1.5.0 series, that the message is suboptimal.  After all, the change
may be something the user might want to get rid of, and "updating" would
be absolutely a wrong thing to do if that is the case.

I prepared two alternatives to solve this.  Both aim to reword the message
to more neutral "locally modified".

This patch is a more intrusive variant that changes the message for only
Porcelain commands ("add" and "reset") while keeping the plumbing
"update-index" intact.

03db4525d3 Support gitlinks in fast-import.
Currently fast-import/export cannot be used for
repositories with submodules. This patch extends
the relevant programs to make them correctly
process gitlinks.

Links can be represented by two forms of the
Modify command:

M 160000 SHA1 some/path

which sets the link target explicitly, or

M 160000 :mark some/path

where the mark refers to a commit. The latter
form can be used by importing tools to build
all submodules simultaneously in one physical
repository, and then simply fetch them apart.

4d26467279 builtin-rm: fix index lock file path
When hold_locked_index() is called with a relative git_dir and you are
outside the work tree, the lock file become relative to the current

ac9391093f restore legacy behavior for read_sha1_file()
Since commit 8eca0b47ff, it is possible
for read_sha1_file() to return NULL even with existing objects when they
are corrupted.  Previously a corrupted object would have terminated the
program immediately, effectively making read_sha1_file() return NULL
only when specified object is not found.

Let's restore this behavior for all users of read_sha1_file() and
provide a separate function with the ability to not terminate when
bad objects are encountered.

ec05df353c git-submodule - make "submodule add" more strict, and document it
This change makes "submodule add" much more strict in the arguments it
takes, and is intended to address confusion as recently noted on the
git-list. With this change, the required syntax is:

	$ git submodule add URL path

Specifically, this eliminates the form

	$ git submodule add URL

which was confused by more than one person as

	$ git submodule add path

With this patch, the URL locating the submodule's origin repository can be
either an absolute URL, or (if it begins with ./ or ../) can express the
submodule's repository location relative to the superproject's origin.

This patch also eliminates a third form of URL, which was relative to the
superproject's top-level directory (not its repository).  Any URL that was
neither absolute nor matched ./*|../* was assumed to point to a
subdirectory of the superproject as the location of the submodule's origin
repository.  This URL form was confusing and does not seem to correspond
to an important use-case.  Specifically, no-one has identified the need to
clone from a repository already in the superproject's tree, but if this is
needed it is easily done using an absolute URL: $(pwd)/relative-path.  So,
no functionality is lost with this patch. (t6008-rev-list-submodule.sh did
rely upon this relative URL, fixed by using $(pwd).)

Following this change, there are exactly four variants of
submodule-add, as both arguments have two flavors:

URL can be absolute, or can begin with ./|../ and thus names the
submodule's origin relative to the superproject's origin.

Note: With this patch, "submodule add" discerns an absolute URL as
matching /*|*:*: e.g., URL begins with /, or it contains a :.  This works
for all valid URLs, an absolute path in POSIX, as well as an absolute path
on Windows).

path can either already exist as a valid git repo, or will be cloned from
the given URL.  The first form here eases creation of a new submodule in
an existing superproject as the submodule can be added and tested in-tree
before pushing to the public repository.  However, the more usual form is
the second, where the repo is cloned from the given URL.

This specifically addresses the issue of

	$ git submodule add a/b/c

attempting to clone from a repository at "a/b/c" to create a new module
in "c". This also simplifies description of "relative URL" as there is now
exactly *one* form: a URL relative to the parent's origin repo.

find-rev and rebase error out on svm because git-svn doesn't trace the
original svn revision numbers back to git commits. The updated test
case, included in the patch, shows the issue and passes with the rest of

This fixes Git::SVN::find_by_url to find branches based on the
svm:source URL, where useSvmProps is set. Also makes sure cmd_find_rev
and working_head_info use the information they have to correctly track
the source repository. This is enough to get find-rev and rebase

5352a82bab t3404: test two "preserve merges with -p" cases
There are two cases for preserving merges:

  1. The merge base is outside the trunk that is to be rebased.
     Then commits of those other parents must not be picked.

  2. The merge base is inside the trunk that is to be rebased.
     Then all the commits related to that merge must be picked
     and the merge must be redone.

The "preserve merges with -p" test case tested for case 1 only.

0af0ac7ebb Move MERGE_RR from .git/rr-cache/ into .git/
If you want to reuse the rerere cache in another repository, and set
a symbolic link to it, you do not want to have the two repositories
interfer with each other by accessing the _same_ MERGE_RR.

For example, if you use contrib/git-new-workdir to set up a second
working directory, and you have a conflict in one working directory,
but commit in the other working directory first, the wrong "resolution"
will be recorded.

The easy solution is to move MERGE_RR out of the rr-cache/ directory,
which also corresponds with the notion that rr-cache/ contains cached
resolutions, not some intermediate temporary states.

329636b435 t0004: fix timing bug
The test created an initial commit, made .git/objects unwritable and then
exercised various codepaths to create loose commit, tree and blob objects
to make sure the commands notice failures from these attempts.

However, the initial commit was not preceded with test_tick, which made
its object name depend on the timestamp.  The names of all the later tree
and blob objects the test tried to create were static.  If the initial
commit's object name happened to begin with the same two hexdigits as the
tree or blob objects the test later attempted to create, the fan-out
directory in which these tree or blob would be created is already created
when the initial commit was made, and the object creation succeeds, and
commands being tested should not notice any failure --- in short, the test
was bogus.

This makes the fan-out directories also unwritable, and adds test_tick
before the commit object creation to make the test repeatable.

The contents of the file to create a blob from "a" to "60" is to force the
name of the blob object to begin with "1b", which shares the fan-out
directory with the initial commit that is created with the test.  This was
useful when diagnosing the breakage of this test.

8c6202d869 Fix backwards-incompatible handling of core.sharedRepository
06cbe85 (Make core.sharedRepository more generic, 2008-04-16) broke the
traditional setting of core.sharedRepository to true, which was to make
the repository group writable: with umask 022, it would clear the
permission bits for 'other'. (umask 002 did not exhibit this behaviour
since pre-chmod() check in adjust_shared_perm() fails in that case.)

The call to adjust_shared_perm() should only loosen the permission.
If the user has umask like 022 or 002 that allow others to read, the
resulting files should be made readable and writable by group, without
restricting the readability by others.

This patch fixes the adjust_shared_perm() mode tweak based on Junio's
suggestion and adds the appropriate tests to t/t1301-shared-repo.sh.

99d698f1e7 builtin-rerere: more carefully find conflict markers
When a conflicting file contains a line that begin with "=======", rerere
failed to parse conflict markers. This result to a wrong preimage file and
an unexpected error for the user.  The boundary between ours and theirs
not just begin with 7 equals, but is followed by either a SP or a LF.

This patch enforces parsing rules so that markers match in the right order,
and when ambiguous, the command does not autoresolve the conflicted file.

Especially because we are introducing rerere.autoupdate configuration
(which is off by default for safety) that automatically stages the
resolution made by rerere, it is necessary to make sure that we do not
autoresolve when there is any ambiguity.

a9a3e82e6d apply: fix copy/rename breakage
7ebd52a (Merge branch 'dz/apply-again', 2008-07-01) taught "git-apply" to
grok a (non-git) patch that is a concatenation of separate patches that
touch the same file number of times, by recording the postimage of patch
application of previous round and using it as the preimage for later
rounds.

This "incremental" mode of patch application fundamentally contradicts
with the way git rename/copy patches are designed.  When a git patch talks
about a file A getting modified, and a new file B created out of A, like
this:

	diff --git a/A b/A
	--- a/A
	+++ b/A
	... change text here ...
	diff --git a/A b/B
	copy from A
	copy to B
	--- a/A

the second change to produce B does not depend on what is done to A with
the first change in any way.  This is explicitly done so for reviewability
of individual patches.

With this commit, we do not look at 'fn_table' that records the postimage
of previous round when applying a patch to produce a new file out of an
existing file.

603fb11682 Avoid apache complaining about lack of server's FQDN
On some setups, apache will say:
apache2: Could not reliably determine the server's fully qualified
domain name, using $(IP_address) for ServerName

Avoid this message polluting tests output by setting a ServerName in
apache configuration.

b5cd2d1e92 Catch failures from t5540-http-push
git http-push doesn't handle packed-refs, and now the new builtin-clone
created packed refs, the http-push test fails.

Mark the current failure as such, and also catch third test's failure
that went unreported because git push doesn't return an error code when
it says:
 No refs in common and none specified; doing nothing.
Which it does when http-push can't get a list of refs recursively from
$URL/refs/.

d1a4489a56 avoid null SHA1 in oldest reflog
When the user specifies a ref by a reflog entry older than
one we have (e.g., "HEAD@{20 years ago"}), we issue a
warning and give them the "from" value of the oldest reflog
entry. That is, we say "we don't know what happened before
this entry, but before this we know we had some particular
SHA1".

However, the oldest reflog entry is often a creation event
such as clone or branch creation. In this case, the entry
claims that the ref went from "00000..." (the null sha1) to
the new value, and the reflog lookup returns the null sha1.

While this is technically correct (the entry tells us that
the ref didn't exist at the specified time) it is not
terribly useful to the end user. What they probably want
instead is "the oldest useful sha1 that this ref ever had".
This patch changes the behavior such that if the oldest ref
would return the null sha1, it instead returns the first
value the ref ever had.

We never discovered this problem in the test scripts because
we created "fake" reflogs that had only a specified segment
of history. This patch updates the tests with a creation
event at the beginning of history.

0b294c0abf make deleting a missing ref more quiet
If git attempts to delete a ref, but the unlink of the ref
file fails, we print a message to stderr. This is usually a
good thing, but if the error is ENOENT, then it indicates
that the ref has _already_ been deleted. And since that's
our goal, it doesn't make sense to complain to the user.

This harmonizes the error reporting behavior for the
unpacked and packed cases; the packed case already printed
nothing on ENOENT, but the unpacked printed unconditionally.

Additionally, send-pack would, when deleting the tracking
ref corresponding to a remote delete, print "Failed to
delete" on any failure. This can be a misleading
message, since we actually _did_ delete at the remote side,
but we failed to delete locally. Rather than make the
message more precise, let's just eliminate it entirely; the
delete_ref routine already takes care of printing out a much
more specific message about what went wrong.

f95ebf7429 Allow cherry-picking root commits
A root commit couldn't be cherry-picked.  But its semantics can be
defined as simply merging two trees by overlaying disjoint parts
and merging overlapping files without any common ancestor.  You
should be able to rebase originally independent branches on top of
another branch by using this.
