* jc/log-stdin: Add trivial tests for --stdin option to log family Make --stdin option to "log" family read also pathspecs setup_revisions(): do not call get_pathspec() too early Teach --stdin option to "log" family read_revision_from_stdin(): use strbuf Conflicts: revision.c
2009-11-20Teach --stdin option to "log" familyJunio C Hamano
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. This also cleans up the kludge made to bundle.c via cut and paste. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-10-28Add '--bisect' revision machinery argumentLinus Torvalds
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 heuristicJeff King
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()Adam Simpkins
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 BĂ©jar. 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]Lars Hjemli
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'Linus Torvalds
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()Linus Torvalds
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>

2009-04-13show_object(): push path_name() call further downLinus Torvalds
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.

2009-04-13process_{tree,blob}: show objects without bufferingLinus Torvalds
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>

2009-02-28is_kept_pack(): final clean-upJunio C Hamano
Now is_kept_pack() is just a member lookup into a structure, we can write it as such. Also rewrite the sole caller of has_sha1_kept_pack() to switch on the criteria the callee uses (namely, revs->kept_pack_only) between calling has_sha1_kept_pack() and has_sha1_pack(), so that these two callees do not have to take a pointer to struct rev_info as an argument.

This refactors three loops that check if a given packfile is on the ignore_packed list into a function is_kept_pack(). The function returns false for a pack on the list, and true for a pack not on the list, because this list is solely used by "git repack" to pass list of packfiles that do not have corresponding .keep files, i.e. a packfile not on the list is "kept".

2009-02-28has_sha1_kept_pack(): take "struct rev_info"Junio C Hamano
Its "ignore_packed" parameter always comes from struct rev_info. This patch makes the function take a pointer to the surrounding structure, so that the refactoring in the next patch becomes easier to review. There is an unfortunate header file dependency and the easiest workaround is to temporarily move the function declaration from cache.h to revision.h; this will be moved back to cache.h once the function loses this "ignore_packed" parameter altogether in the later part of the series.

2009-02-22format-patch: track several referencesThomas Rast
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.

We already support decorating commits by tags or branches that point to them, but especially when we are looking at multiple branches together, we sometimes want to see _how_ we reached a particular commit. We can abuse the '->util' field in the commit to keep track of that as we walk the commit lists, and get a reasonably useful view into which branch or tag first reaches that commit. Of course, if the commit is reachable through multiple sources (which is common), our particular choice of "first" reachable is entirely random and depends on the particular path we happened to follow.

2008-08-30rev-list: fix --reverse interaction with --parentsThomas Rast
--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().

2008-08-25Fix "git log -i --grep"Jeff King
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.

2008-08-02revision traversal: show full history with merge simplificationJunio C Hamano
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 flagJohannes Schindelin
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.

2008-04-10log: teach "terminator" vs "separator" mode to "--pretty=format"Junio C Hamano
This attached patch introduces a single bit "use_terminator" in "struct rev_info", which is normally false (i.e. most formats use separator semantics) but by flipping it to true, you can ask for terminator semantics just like oneline format does. The function get_commit_format(), which is what parses "--pretty=" option, now takes a pointer to "struct rev_info" and updates its commit_format and use_terminator fields. It used to return the value of type "enum cmit_fmt", but all the callers assigned it to rev->commit_format. There are only two cases the code turns use_terminator on. Obviously, the traditional oneline format (--pretty=oneline) is one of them, and the new case is --pretty=tformat:... that acts like --pretty=format:... but flips the bit on. With this, "--pretty=tformat:%H %s" acts like --pretty=oneline. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2008-02-13Add "--show-all" revision walker flag for debuggingLinus Torvalds
It's really not very easy to visualize the commit walker, because - on purpose - it obvously doesn't show the uninteresting commits! This adds a "--show-all" flag to the revision walker, which will make it show uninteresting commits too, and they'll have a '^' in front of them (it also fixes a logic error for !verbose_header for boundary commits - we should show the '-' even if left_right isn't shown). A separate patch to gitk to teach it the new '^' was sent to paulus. With the change in place, it actually is interesting even for the cases that git doesn't have any problems with, ie for the kernel you can do: gitk -d --show-all v2.6.24.. and you see just how far down it has to parse things to see it all. The use of "-d" is a good idea, since the date-ordered toposort is much better at showing why it goes deep down (ie the date of some of those commits after 2.6.24 is much older, because they were merged from trees that weren't rebased). So I think this is a useful feature even for non-debugging - just to visualize what git does internally more. When it actually breaks out due to the "everybody_uninteresting()" case, it adds the uninteresting commits (both the one it's looking at now, and the list of pending ones) to the list This way, we really list *all* the commits we've looked at. Because we now end up listing commits we may not even have been parsed at all "show_log" and "show_commit" need to protect against commits that don't have a commit buffer entry. That second part is debatable just how it should work. Maybe we shouldn't show such entries at all (with this patch those entries do get shown, they just don't get any message shown with them). But I think this is a useful case. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2007-12-12shortlog: default to HEAD when the standard input is a ttyJunio C Hamano
Instead of warning the user that it is expecting git log output from the standard input (and waiting for the user to type the log from the keyboard, which is a silly thing to do), default to traverse from HEAD when there is no rev parameter given and the standard input is a tty. This factors out a useful helper "add_head()" from builtin-diff.c to a more appropriate place revision.c while renaming it to more descriptive name add_head_to_pending(), as that is what the function is about.

2007-11-14Fix parent rewriting in --early-outputLinus Torvalds
We cannot tell a node that has been checked and found not to be interesting (which does not have the TREECHANGE flag) from a node that hasn't been checked if it is interesting or not, without relying on something else, such as object->parsed. But an object can get the "parsed" flag for other reasons. Which means that "TREECHANGE" has the wrong polarity. This changes the way how the path pruning logic marks an uninteresting commits. From now on, we consider a commit interesting by default, and explicitly mark the ones we decided to prune. The flag is renamed to "TREESAME". Then, this fixes the logic to show the early output with incomplete pruning. It basically says "a commit that has TREESAME set is kind-of-UNINTERESTING", but obviously in a different way than an outright UNINTERESTING commit. Until we parse and examine enough parents to determine if a commit becomes surely "kind-of-UNINTERESTING", we avoid rewriting the ancestry so that later rounds can fix things up.

2007-11-06revision walker: mini clean-upLinus Torvalds
This removes the unnecessary indirection of "revs->prune_fn", since that function is always the same one (or NULL), and there is in fact not even an abstraction reason to make it a function (i.e. its not called from some other file and doesn't allow us to keep the function itself static or anything like that). It then just replaces it with a bit that says "prune or not", and if not pruning, every commit gets TREECHANGE. That in turn means that - if (!revs->prune_fn || (flags & TREECHANGE)) - if (revs->prune_fn && !(flags & TREECHANGE)) just become - if (flags & TREECHANGE) - if (!(flags & TREECHANGE)) respectively. Together with adding the "single_parent()" helper function, the "complex" conditional now becomes if (!(flags & TREECHANGE) && rev->dense && single_parent(commit)) continue; Also indirection of "revs->dense" checking is thrown away the same way, because TREECHANGE bit is set appropriately now.
