'git log --abbrev-commit' added an ellipsis to all commit names that
were abbreviated.  This was particularly annoying if you wanted to
cut&paste the sha1 from the terminal, since selecting by word would
pick up '...'  too.

So use find_unique_abbrev() instead of diff_unique_abbrev() in all
log-related commit sha1 printing routines, and also change the
formatting of the 'Merge: parent1 parent2' line output via
pretty_print_commit().

After "cloning from an empty repository", we have a configuration to
describe the remote's URL and the default ref mappings, but we lack the
branch configuration for the default branch we create on our end,
"master".

It is likely that the empty repository we cloned from will point the
default "master" branch with its HEAD, so prepare the local configuration
to match.

This reverts commit b229d18a, at least
until we figure out how to work better with TopGit that points HEAD to
refs/top-bases/ hierarchy.

When there is more than one file that are changed, running git diff with
GIT_EXTERNAL_DIFF incorrectly diagnoses an programming error and dies.
The check introduced in 479b0ae8 (diff: refactor tempfile cleanup handling,
2009-01-22) to detect a temporary file slot that forgot to remove its
temporary file was inconsistent with the way the codepath to remove the
temporary to mark the slot that it is done with it.

This patch fixes this problem and adds a test case for it.

* maint-1.6.0:
  Make repack less likely to corrupt repository
  fast-export: ensure we traverse commits in topological order
  Clear the delta base cache if a pack is rebuilt

Some platforms refuse to rename a file that is open.  When repacking an
already packed repository without adding any new object, the resulting
pack will contain the same set of objects as an existing pack, and on such
platforms, a newly created packfile cannot replace the existing one.

The logic detected this issue but did not try hard enough to recover from
it.  Especially because the files that needs renaming come in pairs, there
potentially are different failure modes that one can be renamed but the
others cannot.  Asking manual recovery to end users were error prone.

This patch tries to make it more robust by first making sure all the
existing files that need to be renamed have been renamed before
continuing, and attempts to roll back if some failed to rename.

This is based on an initial patch by Robin Rosenberg.

fast-export will only list as parents those commits which have already
been traversed (making it appear as if merges have been squashed if not
all parents have been traversed).  To avoid this silent squashing of

9273b562 (filter-branch: Fix fatal error on bare repositories, 2009-02-03)
fixed a missing check of return status from an underlying command in
git-filter-branch, but there still are places that do not check errors.
For example, the command does not pay attention to the exit status of the
command given by --commit-filter.  It should abort in such a case.

This attempts to fix all the remaining places that fails to checks errors.

In two places, I've had to break apart pipelines in order to check the
error code for the first stage of the pipeline, as discussed here:

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.

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.

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 dbc6c74d, 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

cc0e6c5a (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 aeeae1b7
(revision traversal: allow UNINTERESTING objects to be missing,
2009-01-27).

This is a companion patch to the recent 3d95d92b (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.

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.
