When you have grafts that pretend that a given commit has different parents than the ones recorded in the commit object, it is dangerous to let 'git repack' remove those hidden parents, as you can easily remove the graft and end up with a broken repository. So let's play it safe and keep those parent objects and everything that is reachable by them, in addition to the grafted parents. As this behavior can only be triggered by git pack-objects, and as that command handles duplicate parents gracefully, we do not bother to cull duplicated parents that may result by using both true and grafted parents.

It seems that accessing NTFS partitions with ufsd (at least on my EeePC) has an unnerving bug: if you link() a file and unlink() it right away, the target of the link() will have the correct size, but consist of NULs. It seems as if the calls are simply not serialized correctly, as single-stepping through the function move_temp_to_file() works flawlessly. As ufsd is "Commertial software" (sic!), I cannot fix it, and have to work around it in Git. At the same time, it seems that this fixes msysGit issues 222 and 229 to assume that Windows cannot handle link() && unlink().

adjust_shared_perm() first obtains the mode bits from lstat(2), expecting to find what the result of applying user's umask is, and then tweaks it as necessary. When the file to be adjusted is created with mkstemp(3), however, the mode thusly obtained does not have anything to do with user's umask, and we would need to start from 0444 in such a case and there is no point running lstat(2) for such a path. This introduces a new API set_shared_perm() to bypass the lstat(2) and instead force setting the mode bits to the desired value directly. adjust_shared_perm() becomes a thin wrapper to the function.

When "git push" is not told what refspecs to push, it pushes all matching branches to the current remote. For some workflows this default is not useful, and surprises new users. Some have even found that this default behaviour is too easy to trigger by accident with unwanted consequences. Introduce a new configuration variable "push.default" that decides what action git push should take if no refspecs are given or implied by the command line arguments or the current remote configuration. Possible values are: 'nothing' : Push nothing; 'matching' : Current default behaviour, push all branches that already exist in the current remote; 'tracking' : Push the current branch to whatever it is tracking; 'current' : Push the current branch to a branch of the same name, i.e. HEAD.

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 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.

Since it doesn't actually touch its argument, this makes sense. However, we still want to return a non-const version (which requires a cast) so that this: struct ref *a, *b; a = find_ref_by_name(b); works. Unfortunately, you can also silently strip the const from a variable: struct ref *a; const struct ref *b; a = find_ref_by_name(b); This is a classic C const problem because there is no way to say "return the type with the same constness that was passed to us"; we provide the same semantics as standard library functions like strchr.

Since this timestamp is used to check for racy-clean files, it is important to keep it uptodate. For the 'git checkout' command without the '-q' option, this make a huge difference. Before, each and every file which was updated, was racy-clean after the call to unpack_trees() and write_index() but before the GIT process ended. And because of the call to show_local_changes() in builtin-checkout.c, we ended up reading those files back into memory, doing a SHA1 to check if the files was really different from the index. And, of course, no file was different. With this fix, 'git checkout' without the '-q' option should now be almost as fast as with the '-q' option, but not quite, as we still do some few lstat(2) calls more without the '-q' option. Below is some average numbers for 10 checkout's to v2.6.27 and 10 to v2.6.25 of the Linux kernel, to show the difference: before (git version 1.6.2.rc1.256.g58a87): 7.860 user 2.427 sys 19.465 real 52.8% CPU faults: 0 major 95331 minor after: 6.184 user 2.160 sys 17.619 real 47.4% CPU faults: 0 major 38994 minor Signed-off-by: NKjetil Barvik <barvik@broadpark.no> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

Since the filesystem ext4 is now defined as stable in Linux v2.6.28, and ext4 supports nanonsecond resolution timestamps natively, it is time to make USE_NSEC work as expected. This will make racy git situations less likely to happen. For 'git checkout' this means it will be less likely that we have to open, read the contents of the file into RAM, and check if file is really modified or not. The result sould be a litle less used CPU time, less pagefaults and a litle faster program, at least for 'git checkout'. Since the number of possible racy git situations would increase when disks gets faster, this patch would be more and more helpfull as times go by. For a fast Solid State Disk, this patch should be helpfull. Note that, when file operations starts to take less than 1 nanosecond, one would again start to get more racy git situations.

Retesting with a GIT program compiled for gcov usage, I found out that the memmove() calls came from remove_index_entry_at() in read-cache.c, where we have: memmove(istate->cache + pos, istate->cache + pos + 1, (istate->cache_nr - pos) * sizeof(struct cache_entry *)); remove_index_entry_at() is called 4902 times from check_updates() in unpack-trees.c, and each time called we move each cache_entry pointers (from the removed one) one step to the left. Since we have 28828 entries in the cache this time, and if we on average move half of them each time, we in total move approximately 4902 * 0.5 * 28828 * 4 = 282 629 712 bytes, or twice this amount if each pointer is 8 bytes (64 bit). OK, is seems that the function check_updates() is called 28 times, so the estimated guess above had been more correct if check_updates() had been called only once, but the point is: we get lots of bytes moved. To fix this, and use an O(N) algorithm instead, where N is the number of cache_entries, we delete/remove all entries in one loop through all entries. From a retest, the new remove_marked_cache_entries() from the patch below, ended up with the following output line from oprofile: 46 0.0105 15 0.0041 git remove_marked_cache_entries If we can trust the numbers from oprofile in this case, we saved approximately ((7710 - 46) * 20000) / (2 * 1000 * 1000 * 1000) = 0.077 seconds CPU time with this fix for this particular test. And notice that now the CPU did only 46 / 15 = 3.1 cycles/instruction.

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().

The create_directories() function in entry.c currently calls stat() or lstat() for each path component of the pathname 'path' each and every time. For the 'git checkout' command, this function is called on each file for which we must do an update (ce->ce_flags & CE_UPDATE), so we get lots and lots of calls. To fix this, we make a new wrapper to the lstat_cache() function, and call the wrapper function instead of the calls to the stat() or the lstat() functions. Since the paths given to the create_directories() function, is sorted alphabetically, the new wrapper would be very cache effective in this situation. To support it we must update the lstat_cache() function to be able to say that "please test the complete length of 'name'", and also to give it the length of a prefix, where the cache should use the stat() function instead of the lstat() function to test each path component.

In some cases, especially inside the unpack-trees.c file, and inside the verify_absent() function, we can avoid some unnecessary calls to lstat(), if the lstat_cache() function can also be told to keep track of non-existing directories. So we update the lstat_cache() function to handle this new fact, introduce a new wrapper function, and the result is that we save lots of lstat() calls for a removed directory which previously contained lots of files, when we call this new wrapper of lstat_cache() instead of the old one. We do similar changes inside the unlink_entry() function, since if we can already say that the leading directory component of a pathname does not exist, it is not necessary to try to remove a pathname below it!

Commit notes are blobs which are shown together with the commit message. These blobs are taken from the notes ref, which you can configure by the config variable core.notesRef, which in turn can be overridden by the environment variable GIT_NOTES_REF. The notes ref is a branch which contains "files" whose names are the names of the corresponding commits (i.e. the SHA-1). The rationale for putting this information into a ref is this: we want to be able to fetch and possibly union-merge the notes, maybe even look at the date when a note was introduced, and we want to store them efficiently together with the other objects.

Especially on Windows where an opened file cannot be replaced, make sure pack-objects always close packs it is about to replace. Even on non Windows systems, this could save potential bad results if ever objects were to be read from the new pack file using offset from the old index. This should fix t5303 on Windows.

This uses the extended index flag mechanism introduced earlier to mark the entries added to the index via "git add -N" with CE_INTENT_TO_ADD. The logic to detect an "intent to add" entry for the purpose of allowing "git rm --cached $path" is tightened to check not just for a staged empty blob, but with the CE_INTENT_TO_ADD bit. This protects an empty blob that was explicitly added and then modified in the work tree from being dropped with this sequence: $ >empty $ git add empty $ echo "non empty" >empty $ git rm --cached empty Signed-off-by: NJunio C Hamano <gitster@pobox.com>

This can do the lstat() storm in parallel, giving potentially much improved performance for cold-cache cases or things like NFS that have weak metadata caching. Just use "read_cache_preload()" instead of "read_cache()" to force an optimistic preload of the index stat data. The function takes a pathspec as its argument, allowing us to preload only the relevant portion of the index.

Earlier commit 55218834 (checkout: do not lose staged removal, 2008-09-07) tightened the rule to prevent switching branches from losing local changes, so that staged removal of paths can be protected, while attempting to keep a loophole to still allow a special case of switching out of an un-checked-out state. However, the loophole was made a bit too tight, and did not allow switching from one branch (in an un-checked-out state) to check out another branch. The change to builtin-checkout.c in this commit loosens it to allow this, by not insisting the original commit and the new commit to be the same. It also introduces a new function, is_index_unborn (and an associated macro, is_cache_unborn), to check if the repository is truly in an un-checked-out state more reliably, by making sure that $GIT_INDEX_FILE did not exist when populating the in-core index structure. A few places the earlier commit 55218834 added the check for the initial checkout condition are updated to use this function. Signed-off-by: NJunio C Hamano <gitster@pobox.com>
