| * apply --whitespace=error: correctly report new blank lines at endJunio C Hamano2011-09-26
| | | | | | | | | | | | | | | | | | | | Earlier, 77b15bb (apply --whitespace=warn/error: diagnose blank at EOF, 2009-09-03) cheated by reporting the line number of the hunk that contains the offending line that adds new blank lines at the end of the file. All other types of whitespace errors are reported with the line number in the patch file that has the actual offending text. Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The g+s bit on directories to make group ownership inherited is a SysVism --- BSD and most of its descendants do not need it since they do the sane thing by default without g+s. In fact, on some filesystems (but not all --- tmpfs works this way but UFS does not), the kernel of FreeBSD does not even allow non-root users to set setgid bit on directories and produces errors when one tries: $ git init --shared dir fatal: Could not make /tmp/dir/.git/refs writable by group Since the setgid bit would only mean "do what you were going to do already", it's better to avoid setting it. Accordingly, ever since v1.5.5-rc0~59^2 (Do not use GUID on dir in git init --share=all on FreeBSD, 2008-03-05), git on true FreeBSD has done exactly that. Set DIR_HAS_BSD_GROUP_SEMANTICS in the makefile for GNU/kFreeBSD, too, so machines that use glibc with the kernel of FreeBSD get the same fix. This fixes t0001-init.sh and t1301-shared-repo.sh on GNU/kFreeBSD when running tests with --root pointing to a directory that uses tmpfs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Earlier, 582aa00 (git diff too slow for a file, 2010-05-02) unconditionally dropped XDF_NEED_MINIMAL option from the internal xdiff invocation to help performance on pathological cases, while hinting that a follow-up patch could reintroduce it with "--minimal" option from the command line.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 27af01d (xdiff/xprepare: improve O(n*m) performance in xdl_cleanup_records(), 2011-08-17) was supposed to be a performance boost only. However, it unexpectedly changed the behaviour of diff. Revert a part of 27af01d that removes logic that mark lines as "multi-match" (ie. dis[i] == 2). This was preventing the multi-match discard heuristic (performed in xdl_cleanup_records() and xdl_clean_mmatch()) from executing.

Reproduce with any valid old/new patch from which you have removed the "+++ b/FILE" line. You'll see a diagnostic like this fatal: unable to write file '(null)' mode 100644: Bad address and you'll find that FILE has been removed. The above is on glibc-based systems. On other systems, rather than getting "null", you may provoke a segfault as git tries to dereference the NULL file name.

Suppose that the branch you are working on has dir/myfile, and the "other" branch has dir/other but not dir/myfile. Further imagine that you have either modified or removed dir/myfile in your working tree, but you have not run "git add dir/myfile" or "git rm dir/myfile" to tell Git about your local change. Running $ git checkout other dir would add dir/other to the index with the contents taken out of the "other" branch, and check out the paths from the index that match the pathspec "dir", namely, "dir/other" and "dir/myfile", overwriting your local changes to "dir/myfile", even though "other" branch does not even know about that file. Fix it by updating the working tree only with the index entries that was read from the "other" tree. Signed-off-by: Junio C Hamano <gitster@pobox.com>

Whenever the first 40 bytes are a valid hexadecimal sha1 representation, get_one_patchid() returns next_sha1. Once the current line is longer than the fixed buffer, this will break (provided the additional bytes make a valid hexadecimal sha1). As a result patch-id returns incorrect results. Instead, use strbuf and read one line at a time. Helped-by: Jeff King <peff@peff.net> Signed-off-by: Michael Schubert <mschub@elegosoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

The process to move objects from the pending array to the traversal list may have marked objects that are not mentioned as UNINTERESTING, when handle_commit() marked the parents of UNINTERESTING commits mentioned on the command line by calling mark_parents_uninteresting(). This made "rev-list --ancestry-path ^A ..." to mistakenly list commits that are descendants of A's parents but that are not descendants of A itself, as ^A from the command line causes A and its parents marked as UNINTERESTING before coming to limit_list(), and we try to enumerate the commits that are descendants of these commits that are UNINTERESTING before we start walking the history. It actually is too late even if we inspected the pending object array before calling prepare_revision_walk(), as some of the same objects might have been mentioned twice, once as positive and another time as negative. The "rev-list --some-option A --not --all" command may want to notice, even if the resulting set is empty, that the user showed some interest in "A" and do something special about it. Prepare a separate array to keep track of what syntactic element was used to cause each object to appear in the pending array from the command line, and populate it as setup_revisions() parses the command line.

For example, GitHub makes pull-requests available as refs, which can lead to a large number of available refs. This slowness goes away when submodule recursion is turned off: $ git ls-remote git://github.com/rails/rails.git | wc -l 3034 [this takes ~10 seconds of CPU time to complete] git fetch --recurse-submodules=no \ git://github.com/rails/rails.git "refs/*:refs/*" [this still isn't done after 10 _minutes_ of pegging the CPU] git fetch \ git://github.com/rails/rails.git "refs/*:refs/*" You can produce a quicker and simpler test case like this: doit() { head=`git rev-parse HEAD` for i in `seq 1 $1`; do echo $head refs/heads/ref$i done >.git/packed-refs echo "==> $1" rm -rf dest git init -q --bare dest && (cd dest && time git.compile fetch -q .. refs/*:refs/*) } rm -rf repo git init -q repo && cd repo && >file && git add file && git commit -q -m one doit 100 doit 200 doit 400 doit 800 doit 1600 doit 3200 Which yields timings like: # refs seconds of CPU 100 0.06 200 0.24 400 0.95 800 3.39 1600 13.66 3200 54.09 Notice that although the number of refs doubles in each trial, the CPU time spent quadruples. The problem is that the submodule recursion code works something like: - for each ref we fetch - for each commit in git rev-list $new_sha1 --not --all - add modified submodules to list - fetch any newly referenced submodules But that means if we fetch N refs, we start N revision walks. Worse, because we use "--all", the number of refs we must process that constitute "--all" keeps growing, too. And you end up doing O(N^2) ref resolutions. Instead, this patch structures the code like this: - for each sha1 we already have - add $old_sha1 to list $old - for each ref we fetch - add $new_sha1 to list $new - for each commit in git rev-list $new --not $old - add modified submodules to list - fetch any newly referenced submodules This yields timings like: # refs seconds of CPU 100 0.00 200 0.04 400 0.04 800 0.10 1600 0.21 3200 0.39 Note that the amount of effort doubles as the number of refs doubles. Similarly, the fetch of rails.git takes about as much time as it does with --recurse-submodules=no. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Instead of doing anything automatically, detect the situation and give a clean error message. While we're there, also clarify the error message in case '.
