git-commit: partial commit of paths only removed from the index
Because a partial commit is meant to be a way to ignore what are

just record what is in A on the filesystem. The previous patch
made the command sequence to barf, saying that A has not been

Split grep arguments in a way that does not requires to add /dev/null.
In order to (almost) always show the name of the file without
relying on "-H" option of GNU grep, we used to add /dev/null to
the argument list unless we are doing -l or -L. This caused
"/dev/null:0" to show up when -c is given in the output.
It is not enough to add -c to the set of options we do not pass
/dev/null for. When we have too many files, we invoke grep
multiple times and we need to avoid giving a widow filename to
the last invocation -- otherwise we will not see the name.
This keeps two filenames when the argv[] buffer is about to
overflow and we have not finished iterating over the index, so
that the last round will always have at least two paths to work
with (and not require /dev/null).
An obvious and the only exception is when there is only 1 file
that is given to the underlying grep, and in that case we avoid
passing /dev/null and let the external "grep -c" report only the
number of matches.
Documentation/git-config.txt: AsciiDoc tweak to avoid leading dot
Bram Schoenmakers noticed that git-config document was formatted
incorrectly. Depending on the version of AsciiDoc and docbook
toolchain, it is sometimes taken as a numbered example by AsciiDoc,
some other times passed intact to roff format to confuse "man".
Since we refer to the repository metadata directory as $GIT_DIR
elsewhere, work it around by using that symbolic name.

The description of the option gave impression that there
were several formats available by using three dots. There are

This adds more proper rename detection limits. Instead of just checking
the limit against the number of potential rename destinations, we verify
that the rename matrix (which is what really matters) doesn't grow
ridiculously large, and we also make sure that we don't overflow when
doing the matrix size calculation.
This also changes the default limits from unlimited, to a rename matrix
that is limited to 100 entries on a side. You can raise it with the config
entry, or by using the "-l<n>" command line flag, but at least the default
is now a sane number that avoids spending lots of time (and memory) in
situations that likely don't merit it.
The choice of default value is of course very debatable. Limiting the
rename matrix to a 100x100 size will mean that even if you have just one
obvious rename, but you also create (or delete) 10,000 files, the rename
matrix will be so big that we disable the heuristics. Sounds reasonable to
me, but let's see if people hit this (and, perhaps more importantly,
actually *care*) in real life.

Earlier, add_file_to_index() invalidated the path in the cache-tree
but remove_file_from_cache() did not, and the user of the latter
needed to invalidate the entry himself. This led to a few bugs due to
missed invalidate calls already. This patch makes the management of
cache-tree less error prone by making more invalidate calls from lower
level cache API functions.
The rules are:
- If you are going to write the index, you should either maintain
cache_tree correctly.
- If you cannot, alternatively you can remove the entire cache_tree
by calling cache_tree_free() before you call write_cache().
- When you modify the index, cache_tree_invalidate_path() should be
called with the path you are modifying, to discard the entry from
the cache-tree structure.
- The following cache API functions exported from read-cache.c (and
the macro whose names have "cache" instead of "index")
automatically call cache_tree_invalidate_path() for you:
You can modify the index bypassing the above API functions
(e.g. find an existing cache entry from the index and modify it in
place). You need to call cache_tree_invalidate_path() yourself in
such a case.

git-gui: Provide 'uninstall' Makefile target to undo an installation

if git-gui goes to the wrong place during the initial install,

We currently assume that the complete set of files we need to delete

This could differ from what the user actually has installed if they
installed one version then attempt to use another to perform the
uninstall. Right now I'm just going to say that is "pilot error".

git-gui: Font chooser to handle a large number of font families
Simon Sasburg noticed that on X11 if there are more fonts than can
fit in the height of the screen Tk's native tk_optionMenu does not
offer scroll arrows to the user and it is not possible to review
all choices or to select those that are off-screen. On Mac OS X
the tk_optionMenu works properly but is awkward to navigate if the
list is long.
This is a rewrite of our font selection by providing a new modal
dialog that the user can launch from the git-gui Options panel.
The dialog offers the user a scrolling list of fonts in a pane.
An example text shows the user what the font looks like at the size
they have selected. But I have to admit the example pane is less
than ideal. For example in the case of our diff font we really
should show the user an example diff complete with our native diff
syntax coloring.

When making a partial commit, git-commit uses git-ls-files with
the --error-unmatch option to expand and sanity check the user
supplied path patterns. When any path pattern does not match
with the paths known to the index, it errors out, in order to
catch a common mistake to say "git commit Makefiel cache.h"
and end up with a commit that touches only cache.h (notice the
misspelled "Makefile"). This detection however does not work
well when the path has already been removed from the index.
If you drop a path from the index and try to commit that
partially, i.e.
the command complains because git does not know anything about
COPYING anymore.
This introduces a new option --with-tree to git-ls-files and
uses it in git-commit when we build a temporary index to
write a tree object for the partial commit.
When --with-tree=<tree-ish> option is specified, names from the
given tree are added to the set of names the index knows about,
so we can treat COPYING file in the example as known.
Of course, there is no reason to use "git rm" and git-aware
people have long time done:
This replaces the script "git-reset.sh" with "builtin-reset.c".
A few git commands used in the script are called from the builtin also:
"ls-files" to check for unmerged files, "read-tree" for resetting
the index file in "mixed" and "hard" resets, and "update-index" to
refresh at the end in the "mixed" reset and also for the option that
gets selected paths into the index.
The reset option with paths was implemented by Johannes Schindelin.
Since the option that gets selected paths into the index is not
a "reset" like the others because it does not change the HEAD at all,
now the command is showing a warning when the "--mixed" option
is supplied for that purpose.
The following table shows the behaviour of "git reset" for
the different supported options, where X means "changing"
the HEAD, index or working tree:
reset: --soft --mixed --hard -- <paths>
HEAD X X X -
index - X X X

fix doc for --compression argument to pack-objects
git-tag -s must fail if gpg cannot sign the tag.
Make --no-thin the default in git-push to save server resources
1) pushes happen less often than fetches, so the bandwidth saving is
much less visible in that case overall.
2) thin packs have to be complemented with missing delta bases to be
valid, so many received thin packs will take more disk space.
3) the bother of repacking should be distributed amongst "clients"
i.e. fetchers and pushers as much as possible, and not the server
being fetched or pushed, to keep disk and CPU usage low on the
server.
This is why a fetch should get thin packs but a push should not.
Both Nico and I have been assuming that --no-thin was the default
behavior of git-push ever since Nico introduced --fix-thin into the
index-pack process, which allowed fetch and receive-pack to avoid
exploding packfiles received during transfer. This patch finally
makes it so.

Most of this patch code and message was written by Shawn O. Pearce.
I made some tests to know what the problem was, and then I changed
the code related with the SIGPIPE signal.
If the user has misconfigured `user.signingkey` in their .git/config
or just doesn't have any secret keys on their keyring and they ask
for a signed tag with `git tag -s` we better make sure the resulting
tag was actually signed by gpg.
Prior versions of builtin git-tag allowed this failure to slip
by without error as they were not checking the return value of
the finish_command() so they did not notice when gpg exited with
an error exit status. They also did not fail if gpg produced an
empty output or if read_in_full received an error from the read
system call while trying to read the pipe back from gpg.
Finally, we did not actually honor any return value from the do_sign
function as it returns ssize_t but was being stored into an unsigned
long. This caused the compiler to optimize out the die condition,
allowing git-tag to continue along and create the tag object.
However, when gpg gets a wrong username, it exits before any read was done
and then the writing process receives SIGPIPE and program is terminated.
By ignoring this signal, anyway, the function write_or_die gets EPIPE from
write_in_full and exits returning 0 to the system without a message.
Here we better call to write_in_full directly so we can fail
printing a message and return safely to the caller.
With these issues fixed `git-tag -s` will now fail to create the
tag and will report a non-zero exit status to its caller, thereby
allowing automated helper scripts to detect (and recover from)
failure if gpg is not working properly.

In normal use cases, the performance wins are not overly impressive:
we get something like 5-10% due to the slightly better locality of
memory accesses using the packed structure.
However, since the data structure for index entries saves 33% of
memory on 32-bit platforms and 40% on 64-bit platforms, the behavior
when memory gets limited should be nicer.
This is a rather well-contained change. One obvious improvement would
be sorting the elements in one bucket according to their hash, then
using binary probing to find the elements with the right hash value.
As it stands, the output should be strictly the same as previously
unless one uses the option for limiting the amount of used memory, in
which case the created packs might be better.

plain nuts. If git-gui wants someone running Tcl code within it
then would ask someone to supply that Tcl code to it; waiting for
someone to drop any random Tcl code into us is not fantastic idea.
By renaming send to the empty name the procedure will be removed
from the global namespace and Tk will stop responding to random Tcl

git-new-workdir a b
by accident will cause a (and now also b) to have an infinite cycle
in its refs directory. This is caused by git-new-workdir trying
to create the "refs" symlink over again, only during the second
time it is being created within a's refs directory and is now also
pointing back at a's refs.
This causes confusion in git as suddenly branches are named things
like "refs/refs/refs/refs/refs/refs/refs/heads/foo" instead of the
more commonly accepted "refs/heads/foo". Plenty of commands start
to see ambiguous ref names and others just take ages to compute.

of a later memmove() to wrap around and attempt to scribble
almost the entire address space. Not good.
The code that follows the part this patch touches tries to match
the fragment with line offsets. Curiously, that code does not
have the problem --- it guards against reading past the end of
the preimage.
When git-svn uses git-log to find embedded 'git-svn-id'-lines in commit
messages, it can get confused when local history contains merges with
other git-svn branches. But if --first-parent is supplied to git-log,
working_head_info() will only see 'branch-local' commits and thus the
first commit containing a 'git-svn-id' line should refer to the correct
subversion branch.

A function intended to be called from builtins updating refs
by locking them before write, specially those that came from
scripts using "git update-ref".

git-gui: Properly set the state of "Stage/Unstage Hunk" action
Today I found yet another way for the "Stage Hunk" and "Unstage
Hunk" context menu actions to leave the wrong state enabled in
the UI. The problem this time was that I connected the state
determination to the value of $::current_diff_side (the side the
diff is from). When the user was last looking at a diff from the
index side and unstages everything the diff panel goes empty, but
the action stayed enabled as we always assumed unstaging was a
valid action.
This change moves the logic for determining when the action is
enabled away from the individual side selection, as they really
are two unrelated concepts.

git-gui: Fix detaching current branch during checkout
If the user tried to detach their HEAD while keeping the working
directory on the same commit we actually did not completely do
a detach operation internally. The problem was caused by git-gui
not forcing the HEAD symbolic ref to be updated to a SHA-1 hash
when we were not switching revisions. Now we update the HEAD ref
if we aren't currently detached or the hashes don't match.

git-gui: Correct starting of git-remote to handle -w option
Current versions of git-remote apparently are passing the -w option
to Perl as part of the shbang line:
#!/usr/bin/perl -w
this caused a problem in git-gui and gave the user a Tcl error with
the message: "git-remote not supported: #!/usr/bin/perl -w".
The fix for this is to treat the shbang line as a Tcl list and look
at the first element only for guessing the executable name. Once
we know the executable name we use the remaining elements (if any
exist) as arguments to the executable, before the script filename.

archive: specfile support (--pretty=format: in archive files)
Add support for a new attribute, specfile. Files marked as being
specfiles are expanded by git-archive when they are written to an
archive. It has no effect on worktree files. The same placeholders
as those for the option --pretty=format: of git-log et al. can be
used.
The attribute is useful for creating auto-updating specfiles. It is
limited by the underlying function format_commit_message(), though.
E.g. currently there is no placeholder for git-describe like output,
and expanded specfiles can't contain NUL bytes. That can be fixed
in format_commit_message() later and will then benefit users of
git-log, too.

Drop the parameter "msg" of format_commit_message() (as it can be
inferred from the parameter "commit"), add a parameter "template"
in order to avoid accessing the static variable user_format
directly and export the result.

git-p4: Added support for automatically importing newly appearing perforce branches.
If a change in a p4 "branch" appears that hasn't seen any previous commit and
that has a known branch mapping we now try to import it properly. First we
find the p4 change of the source branch that the new p4 branch is based on. Then
we using git rev-list --bisect to locate the corresponding git commit to that change.
Finally we import all changes in the new p4 branch up to the current change and resume
with the regular import.
git-p4: Cleanup; moved the (duplicated) code for turning a branch into a git ref (for example foo -> refs/remotes/p4/<project>/foo) into a separate method.
