This declares such construct like this: struct frotz { int xyzzy; char nitfol[FLEX_ARRAY]; /* more */ }; and git-compat-util.h defines FLEX_ARRAY to 0 for gcc 2.95 and empty for others.

* Fix git-rev-list "date order" with --topo-orderLinus Torvalds2005-11-14
| | | | | | | | | | | | | | | | | | | | This fixes git-rev-list so that when there are multiple branches, we still sort the heads in proper approximate date order even when sorting the output topologically. This makes things like gitk --all -d work sanely and show the branches in date order (where "date order" is obviously modified by the paren-child dependency requirements of the topological sort). The trivial fix is to just build the "work" list in date order rather than inserting the new work entries at the beginning.

* [PATCH] Avoid wasting memory in git-rev-listLinus Torvalds2005-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As pointed out on the list, git-rev-list can use a lot of memory. One low-hanging fruit is to free the commit buffer for commits that we parse. By default, parse_commit() will save away the buffer, since a lot of cases do want it, and re-reading it continually would be unnecessary. However, in many cases the buffer isn't actually necessary and saving it just wastes memory. We could just free the buffer ourselves, but especially in git-rev-list, we actually end up using the helper functions that automatically add parent commits to the commit lists, so we don't actually control the commit parsing directly. Instead, just make this behaviour of "parse_commit()" a global flag. Maybe this is a bit tasteless, but it's very simple, and it makes a noticable difference in memory usage.

* [PATCH] Add 'git show-branch'.Junio C Hamano2005-08-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 'git show-branches' command turns out to be reasonably useful, but painfully slow. So rewrite it in C, using ideas from merge-base while enhancing it a bit more. - Unlike show-branches, it can take --heads (show me all my heads), --tags (show me all my tags), or --all (both). - It can take --more=<number> to show beyond the merge-base. - It shows the short name for each commit in the extended SHA1 syntax. - It can find merge-base for more than two heads. Examples: $ git show-branch --more=6 HEAD is almost the same as "git log --pretty=oneline --max-count=6". $ git show-branch --merge-base master mhf misc finds the merge base of the three given heads. $ git show-branch master mhf misc shows logs from the top of these three branch heads, up to their common ancestor commit is shown. $ git show-branch --all --more=10 is poor-man's gitk, showing all the tags and heads, and going back 10 commits beyond the merge base of those refs.

| | | | | | | | | | | | | | | | | | | Again I left the v2.6.11-tree tag behind. My bad. This commit makes sure that we do not barf when pushing a ref that is a non-commitish tag. You can update a remote ref under the following conditions: * You can always use --force. * Creating a brand new ref is OK. * If the remote ref is exactly the same as what you are pushing, it is OK (nothing is pushed). * You can replace a commitish with another commitish which is a descendant of it, if you can verify the ancestry between them; this and the above means you have to have what you are replacing. * Otherwise you cannot update; you need to use --force.

* Teach parse_commit_buffer about grafting.Junio C Hamano2005-07-31
| | | | | | | | | | | | | Introduce a new file $GIT_DIR/info/grafts (or $GIT_GRAFT_FILE) which is a list of "fake commit parent records". Each line of this file is a commit ID, followed by parent commit IDs, all 40-byte hex SHA1 separated by a single SP in between. The records override the parent information we would normally read from the commit objects, allowing both adding "fake" parents (i.e. grafting), and pretending as if a commit is not a child of some of its real parents (i.e. cauterizing).

* [PATCH] Dereference tag repeatedly until we get a non-tag.Junio C Hamano2005-07-11
| | | | | | | | | | | | | | | | | | | When we allow a tag object in place of a commit object, we only dereferenced the given tag once, which causes a tag that points at a tag that points at a commit to be rejected. Instead, dereference tag repeatedly until we get a non-tag. This patch makes change to two functions: - commit.c::lookup_commit_reference() is used by merge-base, rev-tree and rev-parse to convert user supplied SHA1 to that of a commit. - rev-list uses its own get_commit_reference() to do the same. Dereferencing tags this way helps both of these uses. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] Add a topological sort procedure to commit.cJon Seymour2005-07-06
| | | | | | | | | | | | | | | | | | This introduces an in-place topological sort procedure to commit.c. Given a list of commits, sort_in_topological_order() will perform an in-place topological sort of that list. The invariant that applies to the resulting list is: a reachable from b => ord(b) < ord(a) This invariant is weaker than the --merge-order invariant, but is cheaper to calculate (assuming the list has been identified) and will serve any purpose where only a minimal topological order guarantee is required.

The linearisation produced by this patch is superior in an objective sense to that produced by the existing git-rev-list implementation in that the linearisation produced is guaranteed to have the minimum number of discontinuities, where a discontinuity is defined as an adjacent pair of commits in the output list which are not related in a direct child-parent relationship. With this patch a graph like this: a4 --- | \ \ | b4 | |/ | | a3 | | | | | a2 | | | | c3 | | | | | c2 | b3 | | | /| | b2 | | | c1 | | / | b1 a1 | | | a0 | | / root Sorts like this: = a4 | c3 | c2 | c1 ^ b4 | b3 | b2 | b1 ^ a3 | a2 | a1 | a0 = root Instead of this: = a4 | c3 ^ b4 | a3 ^ c2 ^ b3 ^ a2 ^ b2 ^ c1 ^ a1 ^ b1 ^ a0 = root A test script, t/t6000-rev-list.sh, includes a test which demonstrates that the linearisation produced by --merge-order has less discontinuities than the linearisation produced by git-rev-list without the --merge-order flag specified. To see this, do the following: cd t ./t6000-rev-list.sh cd trash cat actual-default-order cat actual-merge-order The existing behaviour of git-rev-list is preserved, by default. To obtain the modified behaviour, specify --merge-order or --merge-order --show-breaks on the command line. This version of the patch has been tested on the git repository and also on the linux-2.6 repository and has reasonable performance on both - ~50-100% slower than the original algorithm. This version of the patch has incorporated a functional equivalent of the Linus' output limiting algorithm into the merge-order algorithm itself. This operates per the notes associated with Linus' commit 337cb3fb8da45f10fe9a0c3cf571600f55ead2ce. This version has incorporated Linus' feedback regarding proposed changes to rev-list.c. (see: [PATCH] Factor out filtering in rev-list.c) This version has improved the way sort_first_epoch marks commits as uninteresting.
