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/.

Nicolas Pitre	d1af002dc6	[PATCH] delta check This adds knowledge of delta objects to fsck-cache and various object parsing code. A new switch to git-fsck-cache is provided to display the maximum delta depth found in a repository.

Petr Baudis	883550481f	Mark the variable declarations in .h files as extern This allows git to be built even with linkers which are not smart enough to join those symbols, and makes this correct C. Pointed out by several people.	20 years ago
Daniel Barkalow	e9eefa6761	[PATCH] Add function to parse an object of unspecified type (take 2) This adds a function that parses an object from the database when we have to look up its actual type. It also checks the hash of the file, due to its heritage as part of fsck-cache. Signed-Off-By: Daniel Barkalow <barkalow@iabervon.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>	20 years ago
