2011-03-23revision.c: introduce --min-parents and --max-parents optionsLibravatar Michael J Gruber1-7/+21
Introduce --min-parents and --max-parents options which limit the revisions to those commits which have at least (or at most) that many commits, where negative arguments for --max-parents= denote infinity (i.e. no upper limit). In particular: --max-parents=1 is the same as --no-merges; --min-parents=2 is the same as --merges; --max-parents=0 shows only roots; and --min-parents=3 shows only octopus merges Using --min-parents=n and --max-parents=m with n>m gives you what you ask for (i.e. nothing) for obvious reasons, just like when you give --merges (show only merge commits) and --no-merges (show only non-merge commits) at the same time. Also, introduce --no-min-parents and --no-max-parents to do the obvious thing for convenience. We compute the number of parents only when we limit by that, so there is no performance impact when there are no limiters.

2011-03-10git-log: put space after commit markLibravatar Michael J Gruber1-0/+9
Currently, commit marks (left, right, boundary, cherry) are output right before the commit sha1, which makes it difficult to copy sha1s. Sample output for "git log --oneline --cherry": =049c269 t6007: test rev-list --cherry Change this to = 049c269 t6007: test rev-list --cherry which matches exactly the current output of "git log --graph". Leave "git rev-list" output as is (no space) so that they do not break. Adjust "git-svn" which uses "git log --pretty=raw --boundary".

2011-03-09log --cherry: a synonymLibravatar Michael J Gruber1-1/+9
At the porcelain level, because by definition there are many more contributors than integrators, it makes sense to give a handy short-hand for --right-only used with --cherry-mark and --no-merges. Make it so. In other words, this provides "git cherry with rev-list interface". Signed-off-by: Michael J Gruber <git@drmicha.warpmail.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2011-03-09revision.c: introduce --cherry-markLibravatar Michael J Gruber1-3/+18

2011-03-09rev-list/log: factor out revision mark generationLibravatar Michael J Gruber1-0/+16
Currently, we have identical code for generating revision marks ('<', '>', '-') in 5 places. Factor out the code to a single function get_revision_mark() for easier maintenance and extensibility.

2011-02-21revlist.c: introduce --left/right-only for unsymmetric pickingLibravatar Michael J Gruber1-0/+24
The existing "--cherry-pick" does not work with unsymmetric ranges (A..B) for obvious reasons. Introduce "--left-only" and "--right-only" which limit the output to commits on the respective sides of a symmetric range (i.e. only "<" resp. ">" commits as per "--left-right"). This is especially useful for things like git log --cherry-pick --right-only @{u}... which is much more flexible (and descriptive) than git cherry @{u} | sed -ne 's/^+ //p' and potentially more useful than git log --cherry-pick @{u}...

2010-11-23reflogs: clear flags properly in corner caseLibravatar Jeff King1-1/+3
The reflog-walking mechanism is based on the regular revision traversal. We just rewrite the parents of each commit in fake_reflog_parent to point to the commit in the next reflog entry instead of the real parents. However, the regular revision traversal tries not to show the same commit twice, and so sets the SHOWN flag on each commit it shows. In a reflog, however, we may want to see the same commit more than once if it appears in the reflog multiple times (which easily happens, for example, if you do a reset to a prior state). The fake_reflog_parent function takes care of this by clearing flags, including SHOWN. Unfortunately, it does so at the very end of the function, and it is possible to return early from the function if there is no fake parent to set up (e.g., because we are at the very first reflog entry on the branch). In such a case the flag is not cleared, and the entry is skipped by the revision traversal machinery as already shown. You can see this by walking the log of a ref which is set to its very first commit more than once (the test below shows such a situation). In this case the reflog walk will fail to show the entry for the initial creation of the ref. We don't want to simply move the flag-clearing to the top of the function; we want to make sure flags set during the fake-parent installation are also cleared. Instead, let's hoist the flag-clearing out of the fake_reflog_parent function entirely. It's not really about fake parents anyway, and the only caller is the get_revision machinery.

2010-06-12rev-list: introduce --count optionLibravatar Thomas Rast1-0/+2
Add a --count option that, instead of actually listing the commits, merely counts them. This is mostly geared towards script use, and to this end it acts specially when used with --left-right: it outputs the left and right counts separately. Previously, scripts would have to run a shell loop or small inline script over to achieve the same. (Without --left-right, a simple |wc -l does the job.)

2010-06-06revision: Turn off history simplification in --ancestry-path modeLibravatar Johan Herland1-0/+1
When using --ancestry-path together with history simplification (typically triggered by path limiting), history simplification would get in the way of --ancestry-path by prematurely removing the parent links between commits on which the ancestry path calculations are made. This patch disables this history simplification when --ancestry-path is enabled. This is similar to what e.g. --full-history already does. The patch also includes a simple testcase verifying that --ancestry-path works together with path limiting.

2010-06-02DWIM 'git show -5' to 'git show --do-walk -5'Libravatar Jonathan Nieder1-0/+4
To show the last two commits with one command, one might try 1) git show -s master~2.. 2) git show -s ^master~2 master 3) git show -s master^ master 4) git show -s -2 master Choice (3) works because both commits are listed on the command line. Choices (1) and (2) have worked ever since v1.6.4-rc~3 (Make 'git show' more useful, 2009-07-13) disabled --no-walk in this case because there is no other useful meaning for them to have. Unfortunately, (4) does not work: it outputs only one commit, because --no-walk stays on. So disable --no-walk in this case so ‘git show’ and future ‘git cherry-pick’ can behave as expected. As a side effect, this unfortunately changes the meaning of ‘git log --oneline --decorate --no-walk -5 --all’: instead of listing five refs, after this patch that command would list the five most recent commits.

2010-05-31enums: omit trailing comma for portabilityLibravatar Gary V. Vaughan1-1/+1
Without this patch at least IBM VisualAge C 5.0 (I have 5.0.2) on AIX 5.1 fails to compile git. enum style is inconsistent already, with some enums declared on one line, some over 3 lines with the enum values all on the middle line, sometimes with 1 enum value per line... and independently of that the trailing comma is sometimes present and other times absent, often mixing with/without trailing comma styles in a single file, and sometimes in consecutive enum declarations. Clearly, omitting the comma is the more portable style, and this patch changes all enum declarations to use the portable omitted dangling comma style consistently. Signed-off-by: Gary V.

2010-04-21revision: --ancestry-pathLibravatar Junio C Hamano1-0/+102
"rev-list A..H" computes the set of commits that are ancestors of H, but excludes the ones that are ancestors of A. This is useful to see what happened to the history leading to H since A, in the sense that "what does H have that did not exist in A" (e.g. when you have a choice to update to H from A). x---x---A---B---C <-- topic / \ x---x---x---o---o---o---o---M---D---E---F---G <-- dev / \ x---o---o---o---o---o---o---o---o---o---o---o---N---H <-- master The result in the above example would be the commits marked with caps letters (except for A itself, of course), and the ones marked with 'o'. When you want to find out what commits in H are contaminated with the bug introduced by A and need fixing, however, you might want to view only the subset of "A..B" that are actually descendants of A, i.e. excluding the ones marked with 'o'. Introduce a new option --ancestry-path to compute this set with "rev-list --ancestry-path A..B". Note that in practice, you would build a fix immediately on top of A and "git branch --contains A" will give the names of branches that you would need to merge the fix into (i.e. topic, dev and master), so this may not be worth paying the extra cost of postprocessing.

2010-03-09show -c: show patch textLibravatar Junio C Hamano1-4/+3
Traditionally, "show" defaulted to "show --cc" (dense combined patch), but asking for combined patch with "show -c" didn't turn the patch output format on; the placement of this logic in setup_revisions() dates back to cd2bdc5 (Common option parsing for "git log --diff" and friends, 2006-04-14). This unfortunately cannot be done as a trivial change of "if dense combined is asked, default to patch format" done in setup_revisions() to "if any combined is asked, default to patch format", as "diff-tree -c" needs to default to raw, while "diff-tree --cc" needs to default to patch, and they share the codepath.

2010-02-20cherry_pick_list: quit early if one side is emptyLibravatar Thomas Rast1-0/+3
The --cherry-pick logic starts by counting the commits on each side, so that it can filter away commits on the bigger one. However, so far it missed an opportunity for optimization: it doesn't need to do any work if either side is empty. This in particular helps the common use-case 'git rebase -i HEAD~$n': it internally uses --cherry-pick, but since HEAD~$n is a direct ancestor the left side is always empty.

2010-01-25"log --author=me --grep=it" should find intersection, not unionLibravatar Junio C Hamano1-1/+2
Historically, any grep filter in "git log" family of commands were taken as restricting to commits with any of the words in the commit log message. However, the user almost always want to find commits "done by this person on that topic". With "--all-match" option, a series of grep patterns can be turned into a requirement that all of them must produce a match, but that makes it impossible to ask for "done by me, on either this or that" with: log --author=me --committer=him --grep=this --grep=that because it will require both "this" and "that" to appear. Change the "header" parser of grep library to treat the headers specially, and parse it as: (all-match-OR (HEADER-AUTHOR me) (HEADER-COMMITTER him) (OR (PATTERN this) (PATTERN that) ) ) Even though the "log" command line parser doesn't give direct access to the extended grep syntax to group terms with parentheses, this change will cover the majority of the case the users would want. This incidentally revealed that one test in t7002 was bogus. It ran: log --author=Thor --grep=Thu --format='%s' and expected (wrongly) "Thu" to match "Thursday" in the author/committer date, but that would never match, as the timestamp in raw commit buffer does not have the name of the day-of-the-week.

2010-01-20Fix "log" family not to be too agressive about showing notesLibravatar Junio C Hamano1-0/+8
Giving "Notes" information in the default output format of "log" and "show" is a sensible progress (the user has asked for it by having the notes), but for some commands (e.g. "format-patch") spewing notes into the formatted commit log message without being asked is too aggressive. Enable notes output only for "log", "show", "whatchanged" by default and only when the user didn't ask any specific --pretty/--format from the command line; users can explicitly override this default with --show-notes and --no-notes option.
