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.

If an unreferenced object exists in both a local pack and in either a pack
residing in an alternate object database or a local kept pack, then the
pack-objects call made by repack will loosen that object only to have it
immediately pruned by repack's call to prune-packed.

This option to pack-objects/rev-list was created to improve the -A and -a
options of repack. It was found to be lacking in that it did not provide
the ability to differentiate between local and non-local kept packs, and
found to be unnecessary since objects residing in local kept packs can be
filtered out by the --honor-pack-keep option.

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.

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.

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.

Now is_kept_pack() is just a member lookup into a structure, we can write
it as such.
Also rewrite the sole caller of has_sha1_kept_pack() to switch on the
criteria the callee uses (namely, revs->kept_pack_only) between calling
has_sha1_kept_pack() and has_sha1_pack(), so that these two callees do not
have to take a pointer to struct rev_info as an argument.
This removes the header file dependency issue temporarily introduced by
the earlier commit, so we revert changes associated to that as well.

This removes --unpacked=<packfile> parameter from the revision parser, and
rewrites its use in git-repack to pass a single --kept-pack-only option
instead.
The new --kept-pack-only option means just that. When this option is
given, is_kept_pack() that used to say "not on the --unpacked=<packfile>
list" now says "the packfile has corresponding .keep file".

This refactors three loops that check if a given packfile is on the
ignore_packed list into a function is_kept_pack(). The function returns
false for a pack on the list, and true for a pack not on the list, because
this list is solely used by "git repack" to pass list of packfiles that do
not have corresponding .keep files, i.e. a packfile not on the list is
"kept".

Its "ignore_packed" parameter always comes from struct rev_info. This
patch makes the function take a pointer to the surrounding structure, so
that the refactoring in the next patch becomes easier to review.
There is an unfortunate header file dependency and the easiest workaround
is to temporarily move the function declaration from cache.h to
revision.h; this will be moved back to cache.h once the function loses
this "ignore_packed" parameter altogether in the later part of the
series.

Most of the callers of this function except only one pass NULL to its last
parameter, ignore_packed.
Introduce has_sha1_kept_pack() function that has the function signature
and the semantics of this function, and convert the sole caller that does
not pass NULL to call this new function.
All other callers and has_sha1_pack() lose the ignore_packed parameter.

When no tagger was found (old Git produced tags like this),
no "tagger" line is printed (but this is incompatible with the current

Alternatively, you can pass the option --fake-missing-tagger, forcing
fast-export to fake a tagger
Unspecified Tagger <no-tagger>
with a tag date of the beginning of (Unix) time in the case of a missing
tagger, so that fast-import is still able to import the result.

This is sort of a companion patch to 4723ee9(Close files opened by
lock_file() before unlinking.): on Windows, you cannot delete what
is still open.
This makes test 9300-fast-import pass on Windows for me; quite a few
fast-imports leave temporary packs until the test "blank lines not
necessary after other commands" actually tests for the number of files
in .git/objects/pack/, which has a few temporary packs now.
I guess that 8b4eb6b(Do not perform cross-directory renames when
creating packs) was "responsible" for the breakage.

An earlier commit 61b8050 (sending errors to stdout under $PAGER,
2008-02-16) avoided losing the error messages that are sent to the
standard error when $PAGER is in effect by dup2'ing fd 2 to the pager.
his way, showing a tag object that points to a bad object:
$ git show tag-foo
would give the error message to the pager. However, it was not quite
right if the user did:
$ git show 2>error.log tag-foo
i.e. use the pager but store the errors in a separate file.

When a tag points at a bad or nonexistent object, we should diagnose the
breakage and exit. An earlier commit 4f3dcc2 (Fix 'git show' on signed

segfault instead; not good.

implemented as a set of recursive functions. In a repository with a deep

find_parent_branch generates branch@rev type branches when one has to
look back through SVN history to properly get the history for a branch
copied from somewhere not already being tracked by git-svn. If in the
process of fetching this history, git-svn is interrupted, then when one
fetches again, it will use whatever was last fetched as the parent
commit and fail to fetch any more history which it didn't get to before
being terminated. This is especially troubling in that different
git-svn copies of the same SVN repository can end up with different
commit sha1s, incorrectly showing the history as divergent and
precluding easy collaboration using git push and fetch.
To fix this, when we initialise the Git::SVN object $gs to search for
and perhaps fetch history, we check if there are any commits in SVN in
the range between the current revision $gs is at, and the top revision
for which we were asked to fill history. If there are commits we're
missing in that range, we continue the fetch from the current revision
to the top, properly getting all history before using it as the parent
for the branch we're trying to create.

According to the message of commit 0fe7c1de16f71312e6adac4b85bddf0d62a47168,
"git diff" with three or more trees expects the merged tree first followed by
the parents, in order. However, this command reversed the order of its
arguments, resulting in confusing diffs. A comment /* Again, the revs are all
reverse */ suggested there was a reason for this, but I can't figure out the
reason, so I removed the reversal of the arguments. Test case included.

The user may put some effort into writing an annotated tag
message. When the tagging process later fails (which can
happen fairly easily, since it may be dependent on gpg being
correctly configured and used), there is no record left on
disk of the tag message.
Instead, let's keep the TAG_EDITMSG file around until we are
sure the tag has been created successfully. If we die
because of an error, the user can recover their text from
that file. Leaving the file in place causes no conflicts;
it will be silently overwritten by the next annotated tag
creation.
This matches the behavior of COMMIT_EDITMSG, which stays
around in case of error.

This avoids the following misleading error message:
error: unable to create temporary sha1 filename ./objects/15: File exists
mkstemp can fail for many reasons, one of which, ENOENT, can occur if
the directory for the temp file doesn't exist. create_tmpfile tried to
handle this case by always trying to mkdir the directory, even if it
already existed. This caused errno to be clobbered, so one cannot tell
why mkstemp really failed, and it truncated the buffer to just the
directory name, resulting in the strange error message shown above.
Note that in both occasions that I've seen this failure, it has not been
due to a missing directory, or bad permissions, but some other, unknown
mkstemp failure mode that did not occur when I ran git again. This code
could perhaps be made more robust by retrying mkstemp, in case it was a
transient failure.
