2011-03-23revision.c: introduce --min-parents and --max-parents optionsLibravatar Michael J Gruber1-2/+2
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/+1
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".

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.

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}...

2010-06-12rev-list: introduce --count optionLibravatar Thomas Rast1-0/+5
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.)

2010-04-21revision: --ancestry-pathLibravatar Junio C Hamano1-0/+1
"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 Hamano1-0/+1
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. These command specific defaults are now handled in the new "tweak" callback that can be customized by individual command implementations. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-03-09revision: introduce setup_revision_optLibravatar Junio C Hamano1-1/+5
So far the last parameter to setup_revisions() was to specify the default ref when the command line did not give any (typically "HEAD"). This changes it to take a pointer to a structure so that we can add other information without touching too many codepaths in later patches. There is no functionality change.

2010-01-20Fix "log" family not to be too agressive about showing notesLibravatar Junio C Hamano1-0/+3
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. Parts of tests are taken from Jeff King's fix. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Move the logic to read revs from standard input that rev-list knows about from it to revision machinery, so that all the users of setup_revisions() can feed the list of revs from the standard input when "--stdin" is used on the command line. Allow some users of the revision machinery that want different semantics from the "--stdin" option to disable it by setting an option in the rev_info structure.

2009-10-28Add '--bisect' revision machinery argumentLibravatar Linus Torvalds1-0/+1
I personally use "git bisect visualize" all the time when I bisect, but it turns out that that is not a very flexible model. Sometimes I want to do bisection based on all commits (no pathname limiting), but then visualize the current bisection tree with just a few pathnames because I _suspect_ those pathnames are involved in the problem but am not totally sure about them. And at other times, I want to use other revision parsing logic, none of which is available with "git bisect visualize". So this adds "--bisect" as a revision parsing argument, and as a result it just works with all the normal logging tools. So now I can just do gitk --bisect --simplify-by-decoration filename-here etc. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-09-29improve reflog date/number heuristicLibravatar Jeff King1-1/+2
When we show a reflog, we have two ways of naming the entry: by sequence number (e.g., HEAD@{0}) or by date (e.g., HEAD@{10 minutes ago}). There is no explicit option to set one or the other, but we guess based on whether or not the user has provided us with a date format, showing them the date version if they have done so, and the sequence number otherwise. This usually made sense if the use did something like "git log -g --date=relative". However, it didn't make much sense if the user set the date format using the log.date config variable; in that case, all of their reflogs would end up as dates. This patch records the source of the date format and only triggers the date-based view if --date= was given on the command line. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Shawn O.

* as/maint-graph-interesting-fix: Add tests for rev-list --graph with options that simplify history graph API: fix bug in graph_is_interesting()
2009-08-21graph API: fix bug in graph_is_interesting()Libravatar Adam Simpkins1-0/+1
Previously, graph_is_interesting() did not behave quite the same way as the code in get_revision(). As a result, it would sometimes think commits were uninteresting, even though get_revision() would return them. This resulted in incorrect lines in the graph output. This change creates a get_commit_action() function, which graph_is_interesting() and simplify_commit() both now use to determine if a commit will be shown. It is identical to the old simplify_commit() behavior, except that it never calls rewrite_parents(). This problem was reported by Santi Béjar. The following command would exhibit the problem before, but now works correctly: git log --graph --simplify-by-decoration --oneline v1.6.3.3 Previously git graph did not display the output for this command correctly between f29ac4f and 66996ec, among other places.

2009-08-18git-log: allow --decorate[=short|full]Libravatar Lars Hjemli1-0/+3
Commit de435ac0 changed the behavior of --decorate from printing the full ref (e.g., "refs/heads/master") to a shorter, more human-readable version (e.g., just "master"). While this is nice for human readers, external tools using the output from "git log" may prefer the full version. This patch introduces an extension to --decorate to allow the caller to specify either the short or the full versions.

2009-06-29git log: add '--merges' flag to match '--no-merges'Libravatar Linus Torvalds1-0/+1
I do various statistics on git, and one of the things I look at is merges, because they are often interesting events to count ("how many merges vs how much 'real development'" kind of statistics). And you can do it with some fairly straightforward scripting, ie git rev-list --parents HEAD | grep ' .* ' | git diff-tree --always -s --pretty=oneline --stdin | less -S will do it. But I finally got irritated with the fact that we can skip merges with '--no-merges', but we can't do the trivial reverse operation. So this just adds a '--merges' flag that _only_ shows merges. Now you can do the above with just a git log --merges --pretty=oneline which is a lot simpler. It also means that we automatically get a lot of statistics for free, eg git shortlog -ns --merges does exactly what you'd want it to do.

2009-06-03Clean up and simplify rev_compare_tree()Libravatar Linus Torvalds1-2/+3
This simplifies the logic of rev_compare_tree() by removing a special case. It does so by turning the special case of finding a diff to be "all new files" into a more generic case of "all new" vs "all removed" vs "mixed changes", so now the code is actually more powerful and more generic, and the added symmetry actually makes it simpler too. This makes no changes to any existing behavior, but apart from the simplification it does make it possible to some day care about whether all changes were just deletions if we want to. Which we may well want to for merge handling. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2009-04-12show_object(): push path_name() call further downLibravatar Linus Torvalds1-1/+1
In particular, pushing the "path_name()" call _into_ the show() function would seem to allow - more clarity into who "owns" the name (ie now when we free the name in the show_object callback, it's because we generated it ourselves by calling path_name()) - not calling path_name() at all, either because we don't care about the name in the first place, or because we are actually happy walking the linked list of "struct name_path *" and the last component. Now, I didn't do that latter optimization, because it would require some more coding, but especially looking at "builtin-pack-objects.c", we really don't even want the whole pathname, we really would be better off with the list of path components. Why? We use that name for two things: - add_preferred_base_object(), which actually _wants_ to traverse the path, and now does it by looking for '/' characters! - for 'name_hash()', which only cares about the last 16 characters of a name, so again, generating the full name seems to be just unnecessary work. Anyway, so I didn't look any closer at those things, but it did convince me that the "show_object()" calling convention was crazy, and we're actually better off doing _less_ in list-objects.c, and giving people access to the internal data structures so that they can decide whether they want to generate a path-name or not. This patch does that, and then for people who did use the name (even if they might do something more clever in the future), it just does the straightforward "name = path_name(path, component); .. free(name);" thing.

2009-04-12process_{tree,blob}: show objects without bufferingLibravatar Linus Torvalds1-0/+2
Here's a less trivial thing, and slightly more dubious one. I was looking at that "struct object_array objects", and wondering why we do that. I have honestly totally forgotten. Why not just call the "show()" function as we encounter the objects? Rather than add the objects to the object_array, and then at the very end going through the array and doing a 'show' on all, just do things more incrementally. Now, there are possible downsides to this: - the "buffer using object_array" _can_ in theory result in at least better I-cache usage (two tight loops rather than one more spread out one). I don't think this is a real issue, but in theory.. - this _does_ change the order of the objects printed. Instead of doing a "process_tree(revs, commit->tree, &objects, NULL, "");" in the loop over the commits (which puts all the root trees _first_ in the object list, this patch just adds them to the list of pending objects, and then we'll traverse them in that order (and thus show each root tree object together with the objects we discover under it) I _think_ the new ordering actually makes more sense, but the object ordering is actually a subtle thing when it comes to packing efficiency, so any change in order is going to have implications for packing. Good or bad, I dunno. - There may be some reason why we did it that odd way with the object array, that I have simply forgotten. Anyway, now that we don't buffer up the objects before showing them that may actually result in lower memory usage during that whole traverse_commit_list() phase. This is seriously not very deeply tested. It makes sense to me, it seems to pass all the tests, it looks ok, but... Does anybody remember why we did that "object_array" thing? It used to be an "object_list" a long long time ago, but got changed into the array due to better memory usage patterns (those linked lists of obejcts are horrible from a memory allocation standpoint). But I wonder why we didn't do this back then. Maybe there's a reason for it. Or maybe there _used_ to be a reason, and no longer is. Signed-off-by: Junio C Hamano <gitster@pobox.com>

Now is_kept_pack() is just a member lookup into a structure, we can write it as such.

Currently, format-patch can only track a single reference (the In-Reply-To:) for each mail. To ensure proper threading, we should list all known references for every mail. Change the rev_info.ref_message_id field to a string_list, so that we can append references at will, and change the output formatting routines to print all of them in the References: header. The last entry in the list is implicitly assumed to be the In-Reply-To:, which gives output consistent with RFC 2822: The "References:" field will contain the contents of the parent's "References:" field (if any) followed by the contents of the parent's "Message-ID:" field (if any). Note that this is just preparatory work; nothing uses it yet, so all "References:" fields in the output are still only one deep.

2008-08-29rev-list: fix --reverse interaction with --parentsLibravatar Thomas Rast1-0/+1
--reverse did not interact well with --parents, as the included test case shows: in a history like A--B. \ \ `C--M--D the command git rev-list --reverse --parents --full-history HEAD erroneously lists D as having no parents at all. (Without --reverse, it correctly lists M.) This is caused by the machinery driving --reverse: it first grabs all commits through the normal routines, then runs them through the same routines again, effectively simplifying them twice. Fix this by moving the --reverse one level up, into get_revision(). This way we can cleanly grab all commits via the normal calls, then just pop them off the list one by one without interfering with get_revision_internal().

2008-08-24Fix "git log -i --grep"Libravatar Jeff King1-1/+2
This has been broken in v1.6.0 due to the reorganization of the revision option parsing code. The "-i" is completely ignored, but works fine in "git log --grep -i". What happens is that the code for "-i" looks for revs->grep_filter; if it is NULL, we do nothing, since there are no grep filters. But that is obviously not correct, since we want it to influence the later --grep option. Doing it the other way around works, since "-i" just impacts the existing grep_filter option. Instead, we now always initialize the grep_filter member and just fill in options and patterns as we get them. This means that we can no longer check grep_filter for NULL, but instead must check the pattern list to see if we have any actual patterns.

2008-08-20revision.h: make show_early_output an extern which is defined in revision.cLibravatar Brandon Casey1-1/+1
The variable show_early_output is defined in revision.c and should be declared extern in revision.h so that the linker does not complain about multiply defined variables. Signed-off-by: Brandon Casey <casey@nrlssc.navy.mil> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-08-14revision --simplify-merges: use decoration instead of commit->util fieldLibravatar Junio C Hamano1-0/+1
The users of revision walking machinery may want to use the util pointer for their own use. Use decoration to hold the data needed during merge simplification instead. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-08-02revision traversal: show full history with merge simplificationLibravatar Junio C Hamano1-0/+1
The --full-history traversal keeps all merges in addition to non-merge commits that touch paths in the given pathspec. This is useful to view both sides of a merge in a topology like this: A---M---o / / ---O---B even when A and B makes identical change to the given paths. The revision traversal without --full-history aims to come up with the simplest history to explain the final state of the tree, and one of the side branches can be pruned away. The behaviour to keep all merges however is inconvenient if neither A nor B touches the paths we are interested in. --full-history reduces the topology to: ---O---M---o in such a case, without removing M. This adds a post processing phase on top of --full-history traversal to remove needless merges from the resulting history. The idea is to compute, for each commit in the "full history" result set, the commit that should replace it in the simplified history. The commit to replace it in the final history is determined as follows: * In any case, we first figure out the replacement commits of parents of the commit we are looking at. The commit we are looking at is rewritten as if the replacement commits of its original parents are its parents. While doing so, we reduce the redundant parents from the rewritten parent list by not just removing the identical ones, but also removing a parent that is an ancestor of another parent. * After the above parent simplification, if the commit is a root commit, an UNINTERESTING commit, a merge commit, or modifies the paths we are interested in, then the replacement commit of the commit is itself. In other words, such a commit is not dropped from the final result. The first point above essentially means that the history is rewritten in the bottom up direction. We can rewrite the parent list of a commit only after we know how all of its parents are rewritten. This means that the processing needs to happen on the full history (i.e. after limit_list()).

2008-07-23sort_in_topological_order(): avoid setting a commit flagLibravatar Johannes Schindelin1-2/+1
We used to set the TOPOSORT flag of commits during the topological sorting, but we can just as well use the member "indegree" for it: indegree is now incremented by 1 in the cases where the commit used to have the TOPOSORT flag. This is the same behavior as before, since indegree could not be non-zero when TOPOSORT was unset. Incidentally, this fixes the bug in show-branch where the 8th column was not shown: show-branch sorts the commits in topological order, assuming that all the commit flags are available for show-branch's private matters. But this was not true: TOPOSORT was identical to the flag corresponding to the 8th ref. So the flags for the 8th column were unset by the topological sorting.
