Notably, since 68c2ec7 (format-patch: show patch text for the root

avoid possible overflow in delta size filtering computation
On a 32-bit system, the maximum possible size for an object is less than
4GB, while 64-bit systems may cope with larger objects. Due to this
limitation, variables holding object sizes are using an unsigned long
type (32 bits on 32-bit systems, or 64 bits on 64-bit systems).
When large objects are encountered, and/or people play with large delta
depth values, it is possible for the maximum allowed delta size
computation to overflow, especially on a 32-bit system. When this
occurs, surviving result bits may represent a value much smaller than
what it is supposed to be, or even zero. This prevents some objects
from being deltified although they do get deltified when a smaller depth
limit is used. Fix this by always performing a 64-bit multiplication.

bisect: fix quoting TRIED revs when "bad" commit is also "skip"ped
When the "bad" commit was also "skip"ped and when more than one
commit was skipped, the "filter_skipped" function would have
printed something like:
bisect_rev=<hash1>|<hash2>
(where <hash1> and <hash2> are hexadecimal sha1 hashes)
and this would have been evaled later as piping "bisect_rev=<hash1>"
into "<hash2>", which would have failed.
So this patch makes the "filter_skipped" function properly quote
what it outputs, so that it will print something like:
bisect_rev='<hash1>|<hash2>'
which will be properly evaled later. The caller was not stopping
properly because the scriptlet this function returned to be evaled
was not strung together with && and because of this, an error in
an earlier part of the output was simply ignored.
A test case is added to the test suite.
And while at it, we also initialize the VARS, FOUND and TRIED
variables, so that we protect ourselves from environment variables
the user may have with these names.

Make sure objects/pack exists before creating a new pack
In a repository created with git older than f49fb35 (git-init-db: create
"pack" subdirectory under objects, 2005-06-27), objects/pack/ directory is
not created upon initialization. It was Ok because subdirectories are
created as needed inside directories init-db creates, and back then,
packfiles were recent invention.
After the said commit, new codepaths started relying on the presense of
objects/pack/ directory in the repository. This was exacerbated with 8b4eb6b (Do not perform cross-directory renames when creating packs,
2008-09-22) that moved the location temporary pack files are created from
objects/ directory to objects/pack/ directory, because moving temporary to
the final location was done carefully with lazy leading directory creation.
Many packfile related operations in such an old repository can fail
mysteriously because of this.
This commit introduces two helper functions to make things work better.
- odb_mkstemp() is a specialized version of mkstemp() to refactor the
code and teach it to create leading directories as needed;
- odb_pack_keep() refactors the code to create a ".keep" file while
create leading directories as needed.
More friendly message when locking the index fails.
Just saying that index.lock exists doesn't tell the user _what_ to do
to fix the problem. We should give an indication that it's normally
safe to delete index.lock after making sure git isn't running here.

We display empty diffs for files whose timestamps have changed.
Usually, refreshing the index makes those empty diffs go away.
However, when not using the index they are not very useful and
there is no option to suppress them.
This forces on the skip_stat_unmatch option for diff --no-index,
suppressing any empty diffs. This option is also used for diffs
against the index when "diff.autorefreshindex" is set, but that
option does not apply to diff --no-index.

"\" was treated differently in exclude rules depending on whether a
wildcard match was done. For wildcard rules, "\" was de-escaped in
fnmatch, but this was not done for other rules since they used strcmp
instead. A file named "#foo" would not be excluded by "\#foo", but would
be excluded by "\#foo*".
We now treat all rules with "\" as wildcard rules.
Another solution could be to de-escape all non-wildcard rules as we
read them, but we would have to do the de-escaping exactly as fnmatch
does it to avoid inconsistencies.

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: ensure we traverse commits in topological order
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
merge commits, we request commits in topological order.

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.

revision traversal and pack: notice and die on missing commit
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).
Clear the delta base cache during fast-import checkpoint
Otherwise we may reuse the same memory address for a totally
different "struct packed_git", and a previously cached object from
the prior occupant might be returned when trying to unpack an object
from the new pack.

This changes the test-path-utils utility to invoke normalize_path_copy()
instead of normalize_absolute_path() because the latter is about to be
removed.
The test cases in t0060 are adjusted in two regards:
- normalize_path_copy() more often leaves a trailing slash in the result.
This has no negative side effects because the new user of this function,
longest_ancester_length(), already accounts for this behavior.
- The function can fail.
The tests uncover a flaw in normalize_path_copy(): If there are
sufficiently many '..' path components so that the root is reached, such as
in "/d1/s1/../../d2", then the leading slash was lost. This manifested
itself that (assuming there is a repository at /tmp/foo)
$ git add /d1/../tmp/foo/some-file
reported 'pathspec is outside repository'. This is now fixed.
Moreover, the test case descriptions of t0060 now include the test data and
expected outcome.

Using git with GIT_CEILING_DIRECTORIES crashed on Windows due to a failed
assertion in normalize_absolute_path(): This function expects absolute
paths to start with a slash, while on Windows they can start with a drive
letter or a backslash.
This fixes it by using the alternative, normalize_path_copy() instead,
which can handle Windows-style paths just fine.
Secondly, the portability macro PATH_SEP is used instead of expecting
colons to be used as path list delimiter.
The test script t1504 is also changed to help MSYS's bash recognize some
program arguments as path list. (MSYS's bash must translate POSIX-style

filter-branch: do not consider diverging submodules a 'dirty worktree'
At the end of filter-branch in a non-bare repository, the work tree is
updated with "read-tree -m -u HEAD", to carry the change forward in case
the current branch was rewritten. In order to avoid losing any local
change during this step, filter-branch refuses to work when there are
local changes in the work tree.
This "read-tree -m -u HEAD" operation does not affect what commit is
checked out in a submodule (iow, it does not touch .git/HEAD in a
submodule checkout), and checking if there is any local change to the
submodule is not useful.
Staged submodules _are_ considered to be 'dirty', however, as the
"read-tree -m -u HEAD" could result in loss of staged information
otherwise.

filter-branch: Fix fatal error on bare repositories
When git filter-branch is run on a bare repository, it prints out a fatal
error message:
$ git filter-branch branch

WARNING: Ref 'refs/heads/branch' is unchanged
fatal: This operation must be run in a work tree
Note that this fatal error message doesn't prevent git filter-branch from
exiting successfully. (Why doesn't git filter-branch actually exit with an
error when a shell command fails? I'm not sure why it was designed this
way.)
This error message is caused by the following section of code at the end of
git-filter-branch.sh:
if [ "$(is_bare_repository)" = false ]; then
unset GIT_DIR GIT_WORK_TREE GIT_INDEX_FILE
test -z "$ORIG_GIT_DIR" || {
GIT_DIR="$ORIG_GIT_DIR" && export GIT_DIR
}
... elided ...
git read-tree -u -m HEAD
fi
The problem is the call to $(is_bare_repository), which is made before
GIT_DIR and GIT_WORK_TREE are restored. This call always returns "false",
even when we're running in a bare repository. But this means that we will
attempt to call 'git read-tree' even in a bare repository, which will fail
and print an error.
This patch modifies git-filter-branch.sh to restore the original
environment variables before trying to call is_bare_repository.
The parameter n of unpack_callback() can have a value of up to
MAX_UNPACK_TREES. The check at the top of unpack_trees() (its only
(indirect) caller) makes sure it cannot exceed this limit.
unpack_callback() passes it and the array src to unpack_nondirectories(),
which has this loop:
for (i = 0; i < n; i++) {
/* ... */
src[i + o->merge] = o->df_conflict_entry;
o->merge can be 0 or 1, so unpack_nondirectories() potentially accesses
the array src at index MAX_UNPACK_TREES. This patch makes it big enough.
