2009-07-24git repack: keep commits hidden by a graftLibravatar Johannes Schindelin1-0/+2
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.

2009-05-31diff: generate pretty filenames in prep_temp_blob()Libravatar David Aguilar1-0/+2
Naturally, prep_temp_blob() did not care about filenames. As a result, GIT_EXTERNAL_DIFF and textconv generated filenames such as ".diff_XXXXXX". This modifies prep_temp_blob() to generate user-friendly filenames when creating temporary files. Diffing "name.ext" now generates "XXXXXX_name.ext".

2009-04-25Add an option not to use link(src, dest) && unlink(src) when that is unreliableLibravatar Johannes Schindelin1-0/+2
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().

2009-03-28set_shared_perm(): sometimes we know what the final mode bits should look likeLibravatar Junio C Hamano1-1/+2
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.

2009-03-17New config push.default to decide default behavior for pushLibravatar Finn Arne Gangstad1-0/+9
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.

2009-02-28is_kept_pack(): final clean-upLibravatar Junio C Hamano1-0/+1
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.

2009-02-28Consolidate ignore_packed logic moreLibravatar Junio C Hamano1-1/+0
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".

2009-02-28has_sha1_kept_pack(): take "struct rev_info"Libravatar Junio C Hamano1-1/+0
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.

2009-02-26refactor find_ref_by_name() to accept const listLibravatar Jeff King1-1/+1
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.

2009-02-23write_index(): update index_state->timestamp after flushing to diskLibravatar Kjetil Barvik1-1/+1
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: Kjetil Barvik <barvik@broadpark.no> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Talking about --date, one thing I wanted for the 1234567890 date was to get things in the raw format. Sure, you get them with --pretty=raw, but it felt a bit sad that you couldn't just ask for the date in raw format. So here's a throw-away patch (meaning: I won't be re-sending it, because I really don't think it's a big deal) to add "--date=raw". It just prints out the internal raw git format - seconds since epoch plus timezone (put another way: 'date +"%s %z"' format) Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2009-02-19make USE_NSEC work as expectedLibravatar Kjetil Barvik1-3/+3
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.

2009-02-09unlink_entry(): introduce schedule_dir_for_removal()Libravatar Kjetil Barvik1-0/+2
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(). In some cases over 95% of all calls to rmdir() is removed with this patch. Signed-off-by: Kjetil Barvik <barvik@broadpark.no> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-02-09lstat_cache(): swap func(length, string) into func(string, length)Libravatar Kjetil Barvik1-4/+4
Swap function argument pair (length, string) into (string, length) to conform with the commonly used order inside the GIT source code. Also, add a note about this fact into the coding guidelines. Signed-off-by: Kjetil Barvik <barvik@broadpark.no> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-02-08Add mailmap.file as configurational option for mailmap locationLibravatar Marius Storm-Olsen1-0/+1
This allows us to augment the repo mailmap file, and to use mailmap files elsewhere than the repository root. Meaning that the entries in mailmap.file will override the entries in "./.mailmap", should they match.

2009-02-07Remove unused normalize_absolute_path()Libravatar Johannes Sixt1-1/+0
This function is now superseded by normalize_path_copy(). Signed-off-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-02-07Move sanitary_path_copy() to path.c and rename it to normalize_path_copy()Libravatar Johannes Sixt1-0/+1
This function and normalize_absolute_path() do almost the same thing. The former already works on Windows, but the latter crashes. In subsequent changes we will remove normalize_absolute_path(). Here we make the replacement function reusable. On the way we rename it to reflect that it does some path normalization. Apart from that this is only moving around code.
