filter-branch: Remove broken and unnecessary summary of rewritten refs.

There was an attempt to list the refs that were rewritten by filtering
the output of 'git show-ref' for 'refs/original'. But it got the
grep argument wrong, which did not account for the SHA1 that is listed
before the ref.

Moreover, right before this summary is the loop that actually does the
rewriting, and the rewritten refs are listed there anyway. So this extra
summary is plainly too verbose.

unpack-trees: FLEX_ARRAY fixLinus Torvalds Tue, 18 Dec 2007 06:12:03 +0000 (22:12 -0800)

unpack-trees: FLEX_ARRAY fix

In unpack-trees.c (line 593), we do

..
if (same(old, merge)) {
*merge = *old;
} else {
..

and that "merge" is a cache_entry pointer. If we have a non-zero
FLEX_ARRAY size, it will cause us to copy the first few bytes of the
name too.

That is technically wrong even for FLEX_ARRAY being 1, but you'll never
notice, since the filenames should always be the same with the current
code. But if we do the same thing for a rename, we'd be screwed.

threaded pack-objects: Use condition variables for... Johannes Sixt Sun, 16 Dec 2007 19:45:34 +0000 (20:45 +0100)

threaded pack-objects: Use condition variables for thread communication.

In the threaded pack-objects code the main thread and the worker threads
must mutually signal that they have assigned a new pack of work or have
completed their work, respectively. Previously, the code used mutexes that
were locked in one thread and unlocked from a different thread, which is
bogus (and happens to work on Linux).

Here we rectify the implementation by using condition variables: There is
one condition variable on which the main thread waits until a thread
requests new work; and each worker thread has its own condition variable
on which it waits until it is assigned new work or signaled to terminate.

As a cleanup, the worker threads are spawned only after the initial work
packages have been assigned.

After this patch, "written" counts the number of bytes up to and

This allows catching initial indents like '\t ' (a tab followed
by 8 spaces), while previously indent-with-non-tab caught only indents
that consisted entirely of spaces.

This also allows fixing an indent-with-non-tab regression, so we can
again detect indents like '\t \t'.

gitweb: Teach "a=blob" action to be more lenient about blob/file mime type

Since 930cf7dd7cc6b87d173f182230763e1f1913d319 'blob' action knows the
file type; if the file type is not "text/*" or one of common network
image formats/mimetypes (gif, png, jpeg) then the action "blob"
defaulted to "blob_plain". This caused the problem if mimetypes file
was not well suited for web, for example returning "application/x-sh"
for "*.sh" shell scripts, instead of "text/plain" (or other "text/*").

Now "blob" action defaults to "blob_plain" ('raw' view) only if file
is of type which is neither "text/*" nor "image/{gif,png,jpeg}"
AND it is binary file. Otherwise it assumes that it can be displayed
either in <img> tag ("image/*" mimetype), or can be displayed line by
line (otherwise).

It does it by using full refname (with 'refs/heads/' or 'refs/tags/'

commit: allow --amend to reuse message from another commit

After tentatively applying a patch from a contributor, you can get a
replacement patch with corrected code and unusable commit log message.
In such a case, this sequence ought to give you an editor based on the
message in the earlier commit, to let you describe an incremental
improvement:

git reset --hard HEAD^ ;# discard the earlier one

git-svn: handle our top-level path being deleted and later re-added

Previously, git-svn would ignore cases where the path we're
tracking is removed from the repository. This was to prevent
heads with follow-parent from ending up with a tree full of
empty revisions (and thus breaking rename detection).

The previous behavior is fine until the path we're tracking
is re-added later on, leading to the old files being merged
in with the new files in the directory (because the old
files were never marked as deleted)

We will now only remove all the old files locally that were
deleted remotely iff we detect the directory we're in is being
created from scratch.

Peter Baumann for the analysis.

cvsexportcommit: fix massive commitsJeff King Fri, 14 Dec 2007 09:15:47 +0000 (04:15 -0500)

cvsexportcommit: fix massive commits

Because we feed the changed filenames to CVS on the command
line, it was possible for massive commits to overflow the
system exec limits. Instead, we now do an xargs-like split
of the arguments.

This means that we lose some of the atomicity of calling CVS
in one shot. Since CVS commits are not atomic, but the CVS
protocol is, the possible effects of this are not clear;
however, since CVS doesn't provide a different interface,
this is our only option for large commits (short of writing
a CVS client library).

The argument size limit is arbitrarily set to 64kB. This
should be high enough to trigger only in rare cases where it
is necessary, so normal-sized commits are not affected by
the atomicity change.

Note that although the textual content is basically the same only
"git diff --check" provides a colorized version of the problematic

Unify whitespace checkingWincent Colaiuta Thu, 13 Dec 2007 13:32:29 +0000 (14:32 +0100)

Unify whitespace checking

This commit unifies three separate places where whitespace checking was
performed:

- the whitespace checking previously done in builtin-apply.c is
extracted into a function in ws.c

- the equivalent logic in "git diff" is removed

- the emit_line_with_ws() function is also removed because that also
rechecks the whitespace, and its functionality is rolled into ws.c

The new function is called check_and_emit_line() and it does two things:
checks a line for whitespace errors and optionally emits it. The checking
is based on lines of content rather than patch lines (in other words, the
caller must strip the leading "+" or "-"); this was suggested by Junio on
the mailing list to allow for a future extension to "git show" to display
whitespace errors in blobs.

At the same time we teach it to report all classes of whitespace errors
found for a given line rather than reporting only the first found error.

git-commit: squelch needless message during an empty merge

When recording a merge that conflicted and ends up in no changes after
manual resolution, commit callchain looked like this:

cmd_commit() ->
prepare_log_message() ->
run_status() ->
wt_status_print()

This invocation of run_status() is asked to find out if there is a
committable change, but it unconditionally gave instructions such as
"use git-add" at the same time. When in merge, we do allow an empty
change to be recorded, so after showing this message the code still went
ahead and made a commit.

This introduces "nowarn" parameter to run_status() to avoid these
useless messages. If we are not allowed to create an empty commit, we
already call run_status() again in the original codepath, and the
message will be shown from that call anyway.

git-diff --numstat -z: make it machine readable

The "-z" format is all about machine parsability, but showing renamed
paths as "common/{a => b}/suffix" makes it impossible. The scripts would
never have successfully parsed "--numstat -z -M" in the old format.

This fixes the output format in a (hopefully minimally) backward
incompatible way.

* The output without -z is not changed. This has given a good way for
humans to view added and deleted lines separately, and showing the
path in combined, shorter way would preserve readability.

* The output with -z is unchanged for paths that do not involve renames.
Existing scripts that do not pass -M/-C are not affected at all.

* The output with -z for a renamed path is shown in a format that can
easily be distinguished from an unrenamed path.

This is based on Jakub Narebski's patch. Bugs and documentation typos
are mine.

When deciding whether or not to turn on automatic color

tty, we must check whether it is because we started the
pager. This used to be done by checking the pager_in_use
variable.

This variable was set only when the git program being run
started the pager; there was no way for an external program
running git indicate that it had already started a pager.
This patch allows a program to set GIT_PAGER_IN_USE to a

it is because a pager is being used.
