In the show_new_revisions function, the original code:
git rev-parse --not --branches | grep -v $(git rev-parse $refname) |
isn't quite right since one can create a new branch and push it
without any new commits. In that case, two refs will have the same
sha1 but both would get filtered by the 'grep'. In the end, we'll
show ALL the history which is not what we want. Instead, we should
list the branches by name and remove the branch being updated and THEN
pass that list through rev-parse.
Revised as suggested by Jakub Narebski and Junio C Hamano to use
git-for-each-ref instead of git-branch. (Thanks!)

There is some risk that re-opening a regenerated pack file with
different offsets could leave stale entries within the delta base
cache that could be matched up against other objects using the same
"struct packed_git*" and pack offset.
Throwing away the entire delta base cache in this case is safer,
as we don't have to worry about a recycled "struct packed_git*"
matching to the wrong base object, resulting in delta apply
errors while unpacking an object.

Commit dbc6c74d08 "git-svn: handle empty
files marked as symlinks in SVN" caused a regression in an unusual case
where a branch has been created in SVN, later deleted and then created
again from another branch point and the original branch point had empty
files not in the new branch. In some cases git svn fetch will then fail
while trying to fetch the empty file from the wrong SVN revision.
This adds a test case that reproduces the issue.

When initializing a git-svn repository from a Subversion repoository,
it is common to be interested in a path which did not exist in the
initial commit to Subversion. In a large repository, the initial fetch
may take some looking for the earliest existence of the path time while
the user receives no additional feedback. Print the highest revision
number scanned thus far to let the user know something is still
happening.

[ew: minor formatting changes]
Since dbc6c74d08, git-svn has had
an expensive check for broken symlinks that exist in some
repositories. This leads to a heavy performance hit on
repositories with many empty blobs that are not supposed to be
symlinks.
The workaround is enabled by default; and may be disabled via:
git config svn.brokenSymlinkWorkaround false

cc0e6c5 (Handle return code of parse_commit in revision machinery,
2007-05-04) attempted to tighten error checking in the revision machinery,
but it wasn't enough. When get_revision_1() was asked for the next commit
to return, it tries to read and simplify the parents of the commit to be
returned, but an error while doing so was silently ignored and reported as
a truncated history to the caller instead.
This resulted in an early end of "git log" output or a pack that lacks
older commits from "git pack-objects", without any error indication in the
exit status from these commands, even though the underlying parse_commit()
issues an error message to the end user.
Note that the codepath in add_parents_list() that paints parents of an
UNINTERESTING commit UNINTERESTING silently ignores the error when
parse_commit() fails; this is deliberate and in line with aeeae1b
(revision traversal: allow UNINTERESTING objects to be missing,
2009-01-27).

This is a companion patch to the recent 3d95d92 (receive-pack: explain
what to do when push updates the current branch, 2009-01-31).
Deleting the current branch from a remote will result in the next clone
from it not check out anything, among other things. It also is one of the
cause that makes remotes/origin/HEAD a dangling symbolic ref. This patch
still allows the traditional behaviour but with a big warning, and promises
that the default will change to 'refuse' in a future release.

The previous one squelched the diagnositic message we used to issue every
time we enumerated the refs and noticed a dangling ref. This adds the
warning back to the place where the user actually attempts to use it.
Signed-off-by: Junio C Hamano <gitster@pobox.com>
If you prune from the remote "frotz" that deleted the ref your tracking
branch remotes/frotz/HEAD points at, the symbolic ref will become
dangling. We used to detect this as an error condition and issued a
message every time refs are enumerated.
This stops the error message, but moves the warning to "remote prune".

index_is_dirty() in builtin-revert.c checks if the index is dirty.
This patch generalizes this function to check if the index differs
from a revision, i.e. the former index_is_dirty() behavior can now be
achieved by index_differs_from("HEAD", 0).
The second argument "diff_flags" allows to set further diff option
flags like DIFF_OPT_IGNORE_SUBMODULES. See DIFF_OPT_* macros in diff.h
for a list.
index_differs_from() seems to be useful for more than builtin-revert.c,
so it is moved into diff-lib.c and also used in builtin-commit.c.
Yet to mention:
- "rev.abbrev = 0;" can be safely removed.
This has no impact on performance or functioning of neither
setup_revisions() nor run_diff_index().
- rev.pending.objects is free()d because this fixes a leak.

Many tests checked for failure by hand without using test_must_fail (they
probably predate the shell function).
When we know the desired outcome, explicitly check for it, instead of
checking if the result does not match one possible incorrect outcome.
E.g. if you expect a push to be refused, you do not test if the result is
different from what was pushed. Instead, make sure that the ref did not
before and after the push.
The test sequence chdir'ed around and any failure at one point could have
started the next test in an unexpected directory. Fix this problem by
using subshells as necessary.

This is a debug patch which is only to be used while the lstat_cache()
is in the test stage, and should be removed/reverted before the final
relase.
I think it should be useful to catch these warnings, as I it could be
an indication of that the cache would not be very effective if it is
doing ping-pong by switching between different cache types too many
times.
Also, if someone is experimenting with the lstat_cache(), this patch
will maybe be useful while debugging.
If someone is able to trigger the warning, then send a mail to the GIT
mailing list, containing the first 15 lines of the warning, and a
short description of the GIT commands to trigger the warnings.
I hope someone is willing to use this patch for a while, to be able to
catch possible ping-pong's.

Currently inside unlink_entry() if we get a successful removal of one
file with unlink(), we try to remove the leading directories each and
every time. So if one directory containing 200 files is moved to an
other location we get 199 failed calls to rmdir() and 1 successful
call.
To fix this and avoid some unnecessary calls to rmdir(), we schedule
each directory for removal and wait much longer before we do the real
call to rmdir().
Since the unlink_entry() function is called with alphabetically sorted
names, this new function end up being very effective to avoid
unnecessary calls to rmdir(). In some cases over 95% of all calls to
rmdir() is removed with this patch.

Simplify the if-else test in longest_match_lstat_cache() such that we
only have one simple if test. Instead of testing for 'i == cache.len'
or 'i == len', we transform this to a common test for 'i == max_len'.
And to further optimise we use 'i >= max_len' instead of 'i ==
max_len', the reason is that it is now the exact opposite of one part
inside the while-loop termination expression 'i < max_len && name[i]
== cache.path[i]', and then the compiler can probably reuse a test
instruction from it.
We also throw away the arguments to reset_lstat_cache(), such that all
the safeguard logic inside lstat_cache() is handled at one place.

After invoking git add -p I always got the warnings:
Use of uninitialized value $_[3] in exec at Git.pm line 1282.
Use of uninitialized value $args[2] in join or string at Git.pm line 1264.
A bisect showed that these warnings occur in a301973 "add -p: print errors
in separate color" the first time.
They can be reproduced by setting color.ui (or color.interactive) to "auto"
and unsetting color.interactive.help and color.interactive.error.
I am using Perl 5.10.0.
The reason of the warning is that color.interactive.error defaults to
color.interactive.help which defaults to nothing in the specific codepath.
It defaults to 'red bold' some lines above which could lead to the wrong
assumption that it always defaults to 'red bold' now.
This patch lets it default to 'red bold', blowing the warnings away.
