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/.

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	337cb3fb8d	git-rev-list: allow arbitrary head selections, use git-rev-tree syntax This makes git-rev-list use the same command line syntax to mark the commits as git-rev-tree does, and instead of just allowing a start and end commit, it allows an arbitrary list of "interesting" and "uninteresting" commits. For example, imagine that you had three branches (a, b and c) that you are interested in, but you don't want to see stuff that already exists in another persons three releases (x, y and z). You can do git-rev-list a b c ^x ^y ^z (order doesn't matter, btw - feel free to put the uninteresting ones first or otherwise swithc them around), and it will show all the commits that are reachable from a/b/c but not reachable from x/y/z. The old syntax "git-rev-list start end" would not be written as "git-rev-list start ^end", or "git-rev-list ^end start". There's no limit to the number of heads you can specify (unlike git-rev-tree, which can handle a maximum of 16 heads).	20 years ago
Linus Torvalds	3b42a63cb5	git-rev-list: split out commit limiting from main() too. Ok, now I'm happier.	20 years ago
Linus Torvalds	81f2bb1f54	git-rev-list: factor out the commit printing from "main()" Functions that do many things are bad. We should basically just parse the arguments in main(). We're not quite there yet, but it's a step in the right direction.	20 years ago
Linus Torvalds	9d97aa6466	git-rev-list: add "--pretty" command line option That pretty-prints the resulting commit messages, so git-rev-list --pretty HEAD v2.6.12-rc5 \| less -S basically ends up being a log of the changes between -rc5 and current head. It uses the pretty-printing helper function I just extracted from diff-tree.c.	20 years ago
Linus Torvalds	97658004c3	git-rev-list: add "--parents" command line flag It makes rev-list show the list of parents, the same way git-rev-tree does (but without the expense).	20 years ago
Linus Torvalds	8906300f65	git-rev-list: use proper lazy reachability analysis This mean sthat you can give a beginning/end pair to git-rev-list, and it will show all entries that are reachable from the beginning but not the end. For example git-rev-list v2.6.12-rc5 v2.6.12-rc4 shows all commits that are in -rc5 but are not in -rc4.	20 years ago
Linus Torvalds	a6f68d4767	git-rev-list: add "end" commit and "--header" flag The "end" commit is just faking it right now, it's sorting things purely by date, so this is _not_ a reachability analysis. Some day. The "--header" flag causes the commit message to be printed out, with a NUL character separator after it for parseability. This allows you to do things like use "grep -z" to grep for certain authors etc.	20 years ago

Kay Sievers	fcfda02bc7	[PATCH] control/limit output of git-rev-list gitweb.cgi's default view is the log of the last day and git-rev-list can stop crawling the whole repo if we have all our data to display in the browser. Also the rss-feed query needs only the last 20 items. This will speeds up these queries dramatically. usage: rev-list [OPTION] commit-id --max-count=nr --max-age=epoch --min-age=epoch Signed-off-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>	20 years ago
Linus Torvalds	3c249c9506	Add "get_sha1()" helper function. This allows the programs to use various simplified versions of the SHA1 names, eg just say "HEAD" for the SHA1 pointed to by the .git/HEAD file etc. For example, this commit has been done with git-commit-tree $(git-write-tree) -p HEAD instead of the traditional "$(cat .git/HEAD)" syntax.	20 years ago
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. This is necessary to make merge-base work again. Signed-Off-By: Daniel Barkalow <barkalow@iabervon.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>	20 years ago
Linus Torvalds	64745109c4	Add "rev-list" program that uses the new time-based commit listing. This is probably what you'd want to see for "git log".	20 years ago
