2008-04-05gitweb: fallback to system-wide config file (fixup)Libravatar Gerrit Pape1-0/+1

2008-03-27gitweb: fallback to system-wide config file if default config does not existLibravatar Gerrit Pape1-0/+1
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.

2008-03-13filter-branch: use $SHELL_PATH instead of 'sh'Libravatar Jeff King1-0/+1
On some systems, 'sh' isn't very friendly. In particular, t7003 fails on Solaris because it doesn't understand $(). Instead, use the specified SHELL_PATH to run shell code. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-03-13add NO_EXTERNAL_GREP build optionLibravatar Jeff King1-0/+6
Previously, we just chose whether to allow external grep based on the __unix__ define. However, there are systems which define this macro but which have an inferior group (e.g., one that does not support all options used by t7002). This allows users to accept the potential speed penalty to get a more consistent grep experience (and to pass the testsuite).

2008-03-12Makefile: DIFF_OBJS is not special at all these daysLibravatar Junio C Hamano1-7/+5
It used to make sense back when nothing but diff-files, diff-index and friends depended on diffcore infrastructure, but pretty much everything depends on revision infrastructure which in turn depends on DIFF_OBJS. There is no reason to treat them any differently in the Makefile. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2008-02-29use build-time SHELL_PATH in test scriptsLibravatar Jeff King1-2/+6
The top-level Makefile now creates a GIT-BUILD-OPTIONS file which stores any options selected by the make process that may be of use to further parts of the build process. 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>

2008-02-23pack-objects: Add runtime detection of online CPU'sLibravatar Andreas Ericsson1-0/+1
Packing objects can be done in parallell nowadays, but it's only done if the config option pack.threads is set to a value above 1. Because of that, the code-path used is often not the most optimal one. This patch adds a routine to detect the number of online CPU's at runtime (online_cpus()). 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>

An earlier commit e1b3a2c (Build-in merge-recursive) made the subtree merge strategy backend unavailable. This resurrects it.

2008-02-16Build in checkoutLibravatar Daniel Barkalow1-1/+2
The only differences in behavior should be: - git checkout -m with non-trivial merging won't print out merge-recursive messages (see the change in t7201-co.sh) - git checkout -- paths... will give a sensible error message if HEAD is invalid as a commit. - some intermediate states which were written to disk in the shell version (in particular, index states) are only kept in memory in this version, and therefore these can no longer be revealed by later write operations becoming impossible. - when we change branches, we discard MERGE_MSG, SQUASH_MSG, and rr-cache/MERGE_RR, like reset always has. 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.

2008-02-09Move create_branch into a library fileLibravatar Daniel Barkalow1-1/+1
You can also create branches, in exactly the same way, with checkout -b. This introduces branch.{c,h} library files for doing porcelain-level operations on branches (such as creating them with their appropriate default configuration). Signed-off-by: Daniel Barkalow <barkalow@iabervon.org>
2008-02-09Build-in merge-recursiveLibravatar Daniel Barkalow1-1/+1
This makes write_tree_from_memory(), which writes the active cache as a tree and returns the struct tree for it, available to other code. 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).

2008-02-06compat: Add simplified merge sort implementation from glibcLibravatar Brian Downing1-0/+8
qsort in Windows 2000 (and various other C libraries) is a Quicksort with the usual O(n^2) worst case. 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).

2008-02-05help: make 'git-help--browse' usable outside 'git-help'.Libravatar Christian Couder1-1/+1
"git-help--browse" helper is to launch a browser of the user's choice to view the HTML version of git documentation for a given command. It used to take the name of a command, convert it to the path of the documentation by prefixing the directory name and appending the ".html" suffix, and start the browser on the path. 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. The helper now exits with a usage message when no path is given. Signed-off-by: Christian Couder <chriscool@tuxfamily.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2008-01-24pre-POSIX.1-2001 systems do not have <sys/select.h>Libravatar Robert Schiele1-0/+5
POSIX.1-2001 has declaration of select(2) in <sys/select.h>, but in the previous version of SUS, it was declared in <sys/time.h> (which is already included in git-compat-util.h). This introduces NO_SYS_SELECT_H macro in the Makefile to be set on older systems, to skip inclusion of <sys/select.h> that does not exist on them. We could check _POSIX_VERSION with 200112L and do this automatically, but earlier it was reported that the approach does not work well on some vintage of HP-UX. Other systems may get _POSIX_VERSION itself wrong. At least for now, this manual configuration is safer.
