Linus Torvalds	9b66ec0474	Add "--pretty=full" format that also shows committer. Also move the common implementation of parsing the --pretty argument format into commit.c rather than having duplicates in diff-tree.c and rev-list.c.	20 years ago

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/.

Linus Torvalds	000182eacf	pretty_print_commit: add different formats You can ask to print out "raw" format (full headers, full body), "medium" format (author and date, full body) or "short" format (author only, condensed body). Use "git-rev-list --pretty=short HEAD \| less -S" for an example.	20 years ago
Linus Torvalds	e3bc7a3bc7	Add generic commit "pretty print" function. It's really just the header printign function from diff-tree.c, and it's usable for other things too.	20 years ago
Linus Torvalds	ac5155ef59	commit_list_insert: return the new commit list entry This is useful for when we want to insert the next one after this new one, for example.	20 years ago
Linus Torvalds	bd1e17e245	Make "parse_object()" also fill in commit message buffer data. And teach fsck to free it to save memory.	20 years ago
Linus Torvalds	3ff1fbbb94	commit: save the commit buffer off when parsing a commit object. A fair number of the users potentially want to look at the commit objects more closely, and if you worry about memory leaking in certain applications, you can always do a free(commit->buffer); commit->buffer = NULL; by hand after parsing them.	20 years ago
Linus Torvalds	961784ee42	commit: add "lookup_commit_reference()" helper function It's pretty much the same as "lookup_commit()", but it will take tags too, and look up the commit (if any) associated with them.	20 years ago
Nicolas Pitre	bd2c39f58f	[PATCH] don't load and decompress objects twice with parse_object() It turns out that parse_object() is loading and decompressing given object to free it just before calling the specific object parsing function which does mmap and decompress the same object again. This patch introduces the ability to parse specific objects directly from a memory buffer. Without this patch, running git-fsck-cache on the kernel repositorytake: real 0m13.006s user 0m11.421s sys 0m1.218s With this patch applied: real 0m8.060s user 0m7.071s sys 0m0.710s The performance increase is significant, and this is kind of a prerequisite for sane delta object support with fsck.

Daniel Barkalow	58e28af6a4	[PATCH] Allow multiple date-ordered lists Make pop_most_recent_commit() return the same objects multiple times, but only if called with different bits to mark.

Daniel Barkalow	dd97f850c3	[PATCH] Add some functions for commit lists This adds a function for inserting an item in a commit list, a function for sorting a commit list by date, and a function for progressively scanning a commit history from most recent to least recent.
