shell-scripts usage(): consistently exit with non-zero
Earlier conversion of shell scripts to parse-options made usage()
to run "git cmd -h" which in turn emit LONG_USAGE and exit with 0
status. This is inconsistent with the scripts that do not use
parse-options, whose usage() died with the message, exiting with 1.
Reallow git-rebase --interactive --continue if commit is unnecessary
During git-rebase --interactive's --continue implementation we used
to silently restart the rebase if the user had made the commit
for us. This is common if the user stops to edit a commit and
does so by amending it. My recent change to watch git-commit's
exit status broke this behavior.
Thanks to Bernt Hansen for catching it in 1.5.4-rc1.

The prepare_log_message() function serves two purposes:
- Prepares the commit log message template, to be given to the end
user;
- Return true if there is something committable;
7168624c3530d8c7ee32f930f8fb2ba302b9801f (Do not generate full commit
log message if it is not going to be used) cheated to omit the former
when we know the log message template is not going to be used. However,
its replacement logic to see if there is something committable was
botched. When amending, it should compare the index with the parent of
the HEAD, not the current HEAD. Otherwise you cannot run --amend to
fix only the message without changing the tree.
The earlier test stripped away expected number of 'z' but the output
would have been very hard to read once somebody broke the common tail
optimization. Instead, count the number of 'z' and show it, to help
diagnosing the problem better in the future.
Teach diff machinery to display other prefixes than "a/" and "b/"
With the new options "--src-prefix=<prefix>", "--dst-prefix=<prefix>"

and "b/" for the destination prefix.

It's possible for bad clients to commit symlinks without the
5-character "link " prefix in symlinks. So guard around this
bug in SVN and make a best effort to create symlinks if the
"link " prefix is missing.
More information on this SVN bug is described here:
http://subversion.tigris.org/issues/show_bug.cgi?id=2692
To be pedantic, there is still a corner case that neither we nor
SVN can handle: If somebody made a link using a broken SVN
client where "link " is the first part of its path, e.g.
"link sausage", then we'd end up having a symlink which points
to "sausage" because we incorrectly stripped the "link ".
Hopefully this hasn't happened in practice, but if it has,
it's not our fault SVN is broken :)
Thanks to Benoit Sigoure and Sverre Johansen for reporting
and feedback.
git-svn: avoid leaving leftover committer/author info in rebase
We set the 6 environment variables for controlling
committer/author email/name/time for every commit.
We do this in the parent process to be passed to
git-commit-tree, because open3() doesn't afford us the control
of doing it only in the child process. This means we leave them
hanging around in the main process until the next revision comes
around and all 6 environment variables are overwridden again.
Unfortunately, for the last commit, leaving them hanging around
means the git-rebase invocation will pick it up, rewriting the
rebased commit with incorrect author information. This should fix
it.

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

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

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.

Because print_summary() forgot to call diff_setup_done() after futzing with

We need to be extra careful recovering the removed common section, so
that we do not break context nor the changed incomplete line (i.e. the

whitespace: more accurate initial-indent highlighting
Instead of highlighting the entire initial indent, highlight only the

After this patch, "written" counts the number of bytes up to and
including the most recently seen tab. This allows us to detect (and
count) spaces by comparing to "i".
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'.
Also update tests to catch these cases.

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).

- "info" --> "info" program is used

commit: allow --amend to reuse message from another commit
After tentatively applying a patch from a contributor, you can get a

In such a case, this sequence ought to give you an editor based on the

improvement:

Unfortunately, --amend insisted reusing the message from the commit

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.

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.
For consistency, make the two tools report whitespace errors in the
same way (the output of "diff --check" has been tweaked to match
that of "git apply").
Note that although the textual content is basically the same only
"git diff --check" provides a colorized version of the problematic
lines; making "git apply" do colorization will require more extensive
changes (figuring out the diff colorization preferences of the user)
and so that will be a subject for another commit.

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.

Turning pager off when "diff --check" is used is a regression.
This implements earlier Linus's optimization to trim common lines at the
end before passing them down to low level xdiff interface for all of our

We could later enhance this to also trim common leading lines, but that
would need tweaking the output function to add the number of lines
trimmed at the beginning to line numbers that appear in the hunk

do anything other than calling the underlying xdl_diff() to the
