Petr Baudis	17ebe977d7	[PATCH] Tidy up some rev-list-related stuff This patch tidies up the git-rev-list documentation and epoch.c, which are in severe clash with the unwritten coding style now, and quite unreadable. It also fixes up compile failures with older compilers due to variable declarations after code. The patch mostly wraps lines before or on the 80th column, removes plenty of superfluous empty lines and changes comments from // to /* */.

jon@blackcubes.dyndns.org	a3437b8c26	[PATCH] Modify git-rev-list to linearise the commit history in merge order. This patch linearises the GIT commit history graph into merge order which is defined by invariants specified in Documentation/git-rev-list.txt. 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 `337cb3fb8d`. 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. For more details about this change, refer to Documentation/git-rev-list.txt and http://blackcubes.dyndns.org/epoch/.
