2008-06-24refactor pack structure allocationLibravatar Nicolas Pitre1-18/+15
New pack structures are currently allocated in 2 different places and all members have to be initialized explicitly. This is prone to errors leading to segmentation faults as found by Teemu Likonen. Let's have a common place where this structure is allocated, and have all members explicitly initialized to zero.

2008-06-23implement some resilience against pack corruptionsLibravatar Nicolas Pitre2-16/+78
We should be able to fall back to loose objects or alternative packs when a pack becomes corrupted. This is especially true when an object exists in one pack only as a delta but its base object is corrupted. Currently there is no way to retrieve the former object even if the later is available in another pack or loose. This patch allows for a delta to be resolved (with a performance cost) using a base object from a source other than the pack where that delta is located. Same thing for non-delta objects: rather than failing outright, a search is made in other packs or used loose when the currently active pack has it but corrupted. Of course git will become extremely noisy with error messages when that happens. However, if the operation succeeds nevertheless, a simple 'git repack -a -f -d' will "fix" the corrupted repository given that all corrupted objects have a good duplicate somewhere in the object store, possibly manually copied from another source.

* maint: git-svn: make rebuild respect rewriteRoot option Workaround for AIX mkstemp()
2008-06-23git-svn: make rebuild respect rewriteRoot optionLibravatar Jan Krüger2-3/+35
Suppose someone fetches git-svn-ified commits from another repo and then attempts to use 'git-svn init --rewrite-root=foo bar'. Using git svn rebase after that will fail badly: * For each commit tried by working_head_info, rebuild is called indirectly. * rebuild will iterate over all commits and skip all of them because the URL does not match. Because of that no rev_map file is generated at all. * Thus, rebuild will run once for every commit. This takes ages. * In the end there still isn't any rev_map file and thus working_head_info fails. Addressing this behaviour fixes an apparently not too uncommon problem with providing git-svn mirrors of Subversion repositories. Some repositories are accessed using different URLs depending on whether the user has push privileges or not. In the latter case, an anonymous URL is often used that differs from the push URL. Providing a mirror that is usable in both cases becomes a lot more possible with this change.

2008-06-22Shrink the git binary a bit by avoiding unnecessary inline functionsLibravatar Linus Torvalds3-155/+173
So I was looking at the disgusting size of the git binary, and even with the debugging removed, and using -Os instead of -O2, the size of the text section was pretty high. In this day and age I guess almost a megabyte of text isn't really all that surprising, but it still doesn't exactly make me think "lean and mean". With -Os, a surprising amount of text space is wasted on inline functions that end up just being replicated multiple times, and where performance really isn't a valid reason to inline them. In particular, the trivial wrapper functions like "xmalloc()" are used _everywhere_, and making them inline just duplicates the text (and the string we use to 'die()' on failure) unnecessarily. So this just moves them into a "wrapper.c" file, getting rid of a tiny bit of unnecessary bloat. The following numbers are both with "CFLAGS=-Os": Before: [torvalds@woody git]$ size git text data bss dec hex filename 700460 15160 292184 1007804 f60bc git After: [torvalds@woody git]$ size git text data bss dec hex filename 670540 15160 292184 977884 eebdc git so it saves almost 30k of text-space (it actually saves more than that with the default -O2, but I don't think that's necessarily a very relevant number from a "try to shrink git" standpoint). It might conceivably have a performance impact, but none of this should be _that_ performance critical. The real cost is not generally in the wrapper anyway, but in the code it wraps (ie the cost of "xread()" is all in the read itself, not in the trivial wrapping of it).

2008-06-19Make git_dir a path relative to work_tree in setup_work_tree()Libravatar Linus Torvalds3-1/+20
Once we find the absolute paths for git_dir and work_tree, we can make git_dir a relative path since we know pwd will be work_tree. This should save the kernel some time traversing the path to work_tree all the time if git_dir is inside work_tree. Daniel's patch didn't apply for me as-is, so I recreated it with some differences, and here are the numbers from ten runs each. There is some IO for me - probably due to more-or-less random flushing of the journal - so the variation is bigger than I'd like, but whatever: Before: real 0m8.135s real 0m7.933s real 0m8.080s real 0m7.954s real 0m7.949s real 0m8.112s real 0m7.934s real 0m8.059s real 0m7.979s real 0m8.038s After: real 0m7.685s real 0m7.968s real 0m7.703s real 0m7.850s real 0m7.995s real 0m7.817s real 0m7.963s real 0m7.955s real 0m7.848s real 0m7.969s Now, going by "best of ten" (on the assumption that the longer numbers are all due to IO), I'm saying a 7.933s -> 7.685s reduction, and it does seem to be outside of the noise (ie the "after" case never broke 8s, while the "before" case did so half the time). So looks like about 3% to me. Doing it for a slightly smaller test-case (just the "arch" subdirectory) gets more stable numbers probably due to not filling the journal with metadata updates, so we have: Before: real 0m1.633s real 0m1.633s real 0m1.633s real 0m1.632s real 0m1.632s real 0m1.630s real 0m1.634s real 0m1.631s real 0m1.632s real 0m1.632s After: real 0m1.610s real 0m1.609s real 0m1.610s real 0m1.608s real 0m1.607s real 0m1.610s real 0m1.609s real 0m1.611s real 0m1.608s real 0m1.611s where I'ld just take the averages and say 1.632 vs 1.610, which is just over 1% peformance improvement. So it's not in the noise, but it's not as big as I initially thought and measured. (That said, it obviously depends on how deep the working directory path is too, and whether it is behind NFS or something else that might need to cause more work to look up).

2008-06-19t7502-commit.sh: test_must_fail doesn't work with inline environment variablesLibravatar Brandon Casey1-1/+5
When the arguments to test_must_fail() begin with a variable assignment, test_must_fail() attempts to execute the variable assignment as a command. This fails, and so test_must_fail returns with a successful status value without running the command it was intended to test. For example, the following script: #!/bin/sh test_must_fail () { "$@" test $? -gt 0 -a $? -le 129 } foo='wo adrian' test_must_fail foo='yo adrian' sh -c 'echo foo: $foo' always exits zero and prints the message: test.sh: line 3: foo=yo adrian: command not found Test 16 calls test_must_fail in such a way and therefore has not been testing whether git 'do[es] not fire editor in the presence of conflicts'. A workaround is to set and export the variable in a normal way, not using one-shot notation. Because this would affect the remainder of the process, the test is done inside a subshell.

2008-06-18clean up error conventions of remote.c:match_explicitLibravatar Jeff King2-22/+20
match_explicit is called for each push refspec to try to fully resolve the source and destination sides of the refspec. Currently, we look at each refspec and report errors on both the source and the dest side before aborting. It makes sense to report errors for each refspec, since an error in one is independent of an error in the other. However, reporting errors on the 'dst' side of a refspec if there has been an error on the 'src' side does not necessarily make sense, since the interpretation of the 'dst' side depends on the 'src' side (for example, when creating a new unqualified remote ref, we use the same type as the src ref). This patch lets match_explicit return early when the src side of the refspec is bogus. We still look at all of the refspecs before aborting the push, though. At the same time, we clean up the call signature, which previously took an extra "errs" flag. This was pointless, as we didn't act on that flag, but rather just passed it back to the caller. Instead, we now use the more traditional "return -1" to signal an error, and the caller aggregates the error count. This change fixes two bugs, as well: - the early return avoids a segfault when passing a NULL matched_src to guess_ref() - the check for multiple sources pointing to a single dest aborted if the "err" flag was set. Presumably the intent was not to bother with the check if we had no matched_src. However, since the err flag was passed in from the caller, we might abort the check just because a previous refspec had a problem, which doesn't make sense. In practice, this didn't matter, since due to the error flag we end up aborting the push anyway. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
