* sha1-lookup: more memory efficient search in sorted list of SHA-1Junio C Hamano2008-04-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, when looking for a packed object from the pack idx, a simple binary search is used. A conventional binary search loop looks like this: unsigned lo, hi; do { unsigned mi = (lo + hi) / 2; int cmp = "entry pointed at by mi" minus "target"; if (!cmp) return mi; "mi is the wanted one" if (cmp > 0) hi = mi; "mi is larger than target" else lo = mi+1; "mi is smaller than target" } while (lo < hi); "did not find what we wanted" The invariants are: - When entering the loop, 'lo' points at a slot that is never above the target (it could be at the target), 'hi' points at a slot that is guaranteed to be above the target (it can never be at the target). - We find a point 'mi' between 'lo' and 'hi' ('mi' could be the same as 'lo', but never can be as high as 'hi'), and check if 'mi' hits the target. There are three cases: - if it is a hit, we have found what we are looking for; - if it is strictly higher than the target, we set it to 'hi', and repeat the search. - if it is strictly lower than the target, we update 'lo' to one slot after it, because we allow 'lo' to be at the target and 'mi' is known to be below the target. If the loop exits, there is no matching entry. When choosing 'mi', we do not have to take the "middle" but anywhere in between 'lo' and 'hi', as long as lo <= mi < hi is satisfied. When we somehow know that the distance between the target and 'lo' is much shorter than the target and 'hi', we could pick 'mi' that is much closer to 'lo' than (hi+lo)/2, which a conventional binary search would pick. This patch takes advantage of the fact that the SHA-1 is a good hash function, and as long as there are enough entries in the table, we can expect uniform distribution. An entry that begins with for example "deadbeef..." is much likely to appear much later than in the midway of a reasonably populated table. In fact, it can be expected to be near 87% (222/256) from the top of the table. This is a work-in-progress and has switches to allow easier experiments and debugging. Exporting GIT_USE_LOOKUP environment variable enables this code. On my admittedly memory starved machine, with a partial KDE repository (3.0G pack with 95M idx): $ GIT_USE_LOOKUP=t git log -800 --stat HEAD >/dev/null 3.93user 0.16system 0:04.09elapsed 100%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+55588minor)pagefaults 0swaps Without the patch, the numbers are: $ git log -800 --stat HEAD >/dev/null 4.00user 0.15system 0:04.17elapsed 99%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+60258minor)pagefaults 0swaps In the same repository: $ GIT_USE_LOOKUP=t git log -2000 HEAD >/dev/null 0.12user 0.00system 0:00.12elapsed 97%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+4241minor)pagefaults 0swaps Without the patch, the numbers are: $ git log -2000 HEAD >/dev/null 0.05user 0.01system 0:00.07elapsed 100%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+8506minor)pagefaults 0swaps There isn't much time difference, but the number of minor faults seems to show that we are touching much smaller number of pages, which is expected.

* gitweb: fallback to system-wide config file if default config does not existGerrit Pape2008-03-27
| | | | | | | | | | | | | | | | | | | From a distribution point of view, configuration files for applications should reside in /etc/. On the other hand it's convenient for multiple instances of gitweb (e.g. virtual web servers on a single machine) to have a per-instance configuration file, just as gitweb currently supports through the file gitweb_config.perl next to the cgi. To support both at runtime, this commit introduces GITWEB_CONFIG_SYSTEM as a system-wide configuration file which will be used as a fallback if the config file sprecified throug GITWEB_CONFIG does not exist.

Specifically, we store the SHELL_PATH so that it can be used by tests to construct shell scripts on the fly. The format of the GIT-BUILD-OPTIONS file is Bourne shell, and it is sourced by test-lib.sh; all tests can rely on just having $SHELL_PATH correctly set in the environment. The GIT-BUILD-OPTIONS file is written every time the toplevel 'make' is invoked. Since the only users right now are the test scripts, there's no drawback to updating its timestamp. If something build-related depends on this, we can do a trick similar to the one used by GIT-CFLAGS. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

I'm not 100% sure I got the merge recursive setup exactly right; the base for a non-trivial merge in the shell code doesn't seem theoretically justified to me, but I tried to match it anyway, and the tests all pass this way. Other than these items, the results should be identical to the shell version, so far as I can tell.

It also makes available merge_trees(), which does the internal merge of two trees with a known base, and merge_recursive(), which does the recursive internal merge of two commits with a list of common ancestors. The first two of these will be used by checkout -m, and the third is presumably useful in general, although the implementation of checkout -m which entirely matches the behavior of the shell version does not use it (since it ignores the difference of ancestry between the old branch and the new branch).

When pack.threads (or --threads=) is given a value of 0, the number of threads is set to the number of online CPU's. This feature is also documented. As per Nicolas Pitre's recommendations, the default is still to run pack-objects single-threaded unless explicitly activated, either by configuration or by command line parameter. The routine online_cpus() is a rework of "numcpus.c", written by one Philip Willoughby <pgw99@doc.ic.ac.uk>. numcpus.c is in the public domain and can presently be downloaded from http://csgsoft.doc.ic.ac.uk/numcpus/ Signed-off-by: Andreas Ericsson <ae@op5.se> Signed-off-by: Brandon Casey <casey@nrlssc.navy.mil> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Unfortunately, sorting Git trees seems to get very close to that worst case quite often: $ /git/gitbad runstatus # On branch master qsort, nmemb = 30842 done, 237838087 comparisons. This patch adds a simplified version of the merge sort that is glibc's qsort(3). As a merge sort, this needs a temporary array equal in size to the array that is to be sorted, but has a worst-case performance of O(n log n). The complexity that was removed is: * Doing direct stores for word-size and -aligned data. * Falling back to quicksort if the allocation required to perform the merge sort would likely push the machine into swap. Even with these simplifications, this seems to outperform the Windows qsort(3) implementation, even in Windows XP (where it is "fixed" and doesn't trigger O(n^2) complexity on trees).

This updates the division of labor between the caller in help.c and git-help--browser helper. The helper is now responsible for launching a browser of the user's choice on given URLs, and it is the caller's responsibility to tell it the paths to documentation files. This is in preparation to reuse the logic to choose user's preferred browser in instaweb. The helper had a provision for running it without any command name, in which case it showed the toplevel "git(7)" documentation, but the caller in help.c never makes such a call.

This patch moves the functions required by libgit.a from builtin-archive.c to the new file archive.c (which becomes part of libgit.a).

* autoconf: Add checking for unsetenv functionJakub Narebski2008-01-17
| | | | | | | | | Update configure.ac (and config.mak.in) by adding test for unsetenv (NO_UNSETENV). Add comment about NO_UNSETENV to Makefile header, as original commit 731043fd adding compat/unsetenv.c didn't do that.

* Fix git-instaweb breakage on MacOS X due to the limited sed functionalityCharles Bailey2007-12-19
| | | | | | | | | | | | | git-instaweb relied on a pipe in a sed script, but this is not supported by MacOS X sed when using BREs. git-instaweb relies on a working perl in any case, and perl re are more consistent between platforms, so replace sed invocation with an equivalent perl invocation. Also, fix the documented -b "" to work without giving a spurious 'command not found' error. Signed-off-by: Charles Bailey <charles@hashpling.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* rename git-browse--help to git-help--browseJeff King2007-12-16
