In the usage message for "git commit", the --cleanup option appeared
at the end, as one of the "contents options":
usage: git commit [options] [--] <filepattern>...
...
Commit message options

Commit contents options

--allow-empty ok to record an empty change
--cleanup <default> how to strip spaces and #comments from message
This is confusing, in part because it makes it ambiguous whether
--allow-empty, just above, refers to an empty diff or an empty message.
Move --cleanup into the 'message options' group. Also add a pair of
comments to prevent similar oversights in the future.

When making a histogram of delta chain length in the pack, the program
collects number of objects whose delta depth exceeds the MAX_CHAIN limit
in histogram[0], and showed it as the number of items that exceeds the
limit correctly. HOWEVER, it also showed the same number labeled as
"chain length = 0".
In fact, we are not showing the number of objects whose chain length is
zero, i.e. the base objects. Correct this.

Unfortunately the buffer size check lacks the extra space character
which gets inserted at the next non-space character, resulting in

Ack, ack.
There's another easy 5% or so for the built-in object walker: once we've
created the hash from the name, the name isn't interesting any more, and
so something trivial like this can help a bit.
Does it matter? Probably not on its own. But a few more memory saving
tricks and it might all make a difference.
The name of the processed object was duplicated for passing it to
add_object(), but that already calls path_name, which allocates a new
string anyway. So the memory allocated by the xstrdup calls just went

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.

diff --cached: do not borrow from a work tree when a path is marked as assume-unchanged
When the index says that the file in the work tree that corresponds to the
blob object that is used for comparison is known to be unchanged, "diff"
reads from the file and applies convert_to_git(), instead of inflating the
object, to feed the internal diff engine with, because an earlier
benchnark found that it tends to be faster to use this optimization.
However, the index can lie when the path is marked as assume-unchanged.
Disable the optimization for such paths.

pack-objects: don't loosen objects available in alternate or kept packs
If pack-objects is called with the --unpack-unreachable option then it
will unpack (i.e. loosen) all unreferenced objects from local not-kept
packs, including those that also exist in packs residing in an alternate
object database or a locally kept pack. The only user of this option is
git-repack.
In this case, repack will follow the call to pack-objects with a call to
prune-packed, which will delete these newly loosened objects, making the
act of loosening a waste of time. The unnecessary loosening can be
avoided by checking whether an object exists in a non-local pack or a
locally kept pack before loosening it.
This fixes the 'local packed unreachable obs that exist in alternate ODB
are not loosened' test in t7700.

Propagate --exec-path setting to external commands via GIT_EXEC_PATH
Let PATH0=$PATH that was set before the invocation.
Let /foo be a build directory.
Let /pfx be the installation prefix.
Let pfxexecpath=/pfx/libexec/git-core.
The following is going on when 'git --exec-path=/foo gc' is invoked:
1. git sets PATH=/foo:$PATH0 using the path from --exec-path
2. gc execs 'git repack' (note: no dash).
3. Since there is a git in /foo (it's a build directory), /foo/git is
taken.
4. No explicit exec-path is set this time, hence, this secondary git sets
PATH=$pfxexecpath:/foo:$PATH
5. Since 'repack' is not a built-in, execv_dashed_external execs
'git-repack' (note: dash).
6. There is a $pfxexecpath/git-repack, and it is taken.
7. This git-repack runs 'git pack-objects' (note: no dash).
8. There is no git in $pfxexecpath, but there is one in /foo. Hence,
/foo/git is run.
9. pack-objects is a builtin, hence, in effect /foo/git-pack-objects
is run.
As you can see, the way in which we previously set the PATH allowed to
mix gits of different vintage. By setting GIT_EXEC_PATH when --exec-path
was given on the command line, we reduce the confusion.

This option to pack-objects/rev-list was created to improve the -A and -a

found to be unnecessary since objects residing in local kept packs can be
filtered out by the --honor-pack-keep option.

pack-objects: only repack or loosen objects residing in "local" packs
These two features were invented for use by repack when repack will delete
the local packs that have been made redundant. The packs accessible
through alternates are not deleted by repack, so the objects contained in
them are still accessible after the local packs are deleted. They do not
need to be repacked into the new pack or loosened. For the case of
loosening they would immediately be deleted by the subsequent prune-packed
that is called by repack anyway.
This fixes the test
'packed unreachable obs in alternate ODB are not loosened' in t7700.

git-repack.sh: don't use --kept-pack-only option to pack-objects
The --kept-pack-only option to pack-objects treats all kept packs as equal.
This results in objects that reside in an alternate pack that has a .keep
file, not being packed into a newly created pack when the user specifies the
-a option to repack. Since the user may not have any control over the
alternate database, git should not refrain from repacking those objects
even though they are in a pack with a .keep file.
This fixes the 'packed obs in alternate ODB kept pack are repacked' test in
t7700.

t7700-repack: add two new tests demonstrating repacking flaws
1) The new --kept-pack-only mechansim of rev-list/pack-objects has
replaced --unpacked=. This new mechansim does not operate solely on
"local" packs now. The result is that objects residing in an alternate
pack which has a .keep file will not be repacked with repack -a.
This flaw is only apparent when a commit object is the one residing in
an alternate kept pack.
2) The 'repack unpacked objects' and 'loosen unpacked objects' mechanisms
of pack-objects, i.e. --keep-unreachable and --unpack-unreachable,
now do not operate solely on local packs. The --keep-unreachable
option no longer has any callers, but --unpack-unreachable is used when
repack is called with '-A -d' and the local repo has existing packs.
In this case, objects residing in alternate, not-kept packs will be
loosened, and then immediately deleted by repack's call to
prune-packed.
The test must manually call pack-objects to avoid the call to
prune-packed that is made by repack when -d is used.
