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.

2008-07-09revisions: refactor handle_revision_opt into parse_revision_opt.Libravatar Pierre Habouzit1-2/+5
It seems we're using handle_revision_opt the same way each time, have a wrapper around it that does the 9-liner we copy each time instead. handle_revision_opt can be static in the module for now, it's always possible to make it public again if needed.

2008-07-08revisions: split handle_revision_opt() from setup_revisions()Libravatar Pierre Habouzit1-0/+4
Add two fields to struct rev_info: - .def to store --default argument; and - .show_merge 1-bit field. handle_revision_opt() is able to deal with any revision option, and consumes them, and leaves revision arguments or pseudo arguments (like --all, --not, ...) in place. For now setup_revisions() does a pass of handle_revision_opt() again so that code not using it in a parse-opt parser still work the same.

2008-04-10log: teach "terminator" vs "separator" mode to "--pretty=format"Libravatar Junio C Hamano1-1/+2
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 debuggingLibravatar Linus Torvalds1-0/+1
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>
2007-12-11shortlog: default to HEAD when the standard input is a ttyLibravatar Junio C Hamano1-0/+2
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-outputLibravatar Linus Torvalds1-1/+1
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.

2007-11-05revision walker: mini clean-upLibravatar Linus Torvalds1-4/+1
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.

2007-11-05Enhance --early-output formatLibravatar Linus Torvalds1-0/+8
This makes --early-output a bit more advanced, and actually makes it generate multiple "Final output:" headers as it updates things asynchronously. I realize that the "Final output:" line is now illogical, since it's not really final until it also says "done", but It now _always_ generates a "Final output:" header in front of any commit list, and that output header gives you a *guess* at the maximum number of commits available. However, it should be noted that the guess can be completely off: I do a reasonable job estimating it, but it is not meant to be exact. So what happens is that you may get output like this: - at 0.1 seconds: Final output: 2 incomplete .. 2 commits listed .. - half a second later: Final output: 33 incomplete .. 33 commits listed .. - another half a second after that: Final output: 71 incomplete .. 71 commits listed .. - another half second later: Final output: 136 incomplete .. 100 commits listed: we hit the --early-output limit, and .. will only output 100 commits, and after this you'll not .. see an "incomplete" report any more since you got as much .. early output as you asked for! - .. and then finally: Final output: 73106 done .. all the commits .. The above is a real-life scenario on my current kernel tree after having flushed all the caches. Tested with the experimental gitk patch that Paul sent out, and by looking at the actual log output (and verifying that my commit count guesses actually match real life fairly well).

2007-11-04Add "--early-output" log flag for interactive GUI useLibravatar Linus Torvalds1-0/+4
This adds support for "--early-output[=n]" as a flag to the "git log" family of commands. This allows GUI programs to state that they want to get some output early, in order to be able to show at least something quickly, even if the full output may take longer to generate. If no count is specified, a default count of a hundred commits will be used, although the actual numbr of commits output may be smaller depending on how many commits were actually found in the first tenth of a second (or if *everything* was found before that, in which case no early output will be provided, and only the final list is made available). When the full list is generated, there will be a "Final output:" string prepended to it, regardless of whether any early commits were shown or not, so that the consumer can always know the difference between early output and the final list.

This removes the flag internally used by revision traversal to decide which commits are indeed boundaries and renames it to CHILD_SHOWN. builtin-bundle uses the symbol for its verification, but I think the logic it uses it is wrong.

2007-03-06revision walker: Fix --boundary when limitedLibravatar Junio C Hamano1-2/+6
This cleans up the boundary processing in the commit walker. It - rips out the boundary logic from the commit walker. Placing "negative" commits in the revs->commits list was Ok if all we cared about "boundary" was the UNINTERESTING limiting case, but conceptually it was wrong. - makes get_revision_1() function to walk the commits and return the results as if there is no funny postprocessing flags such as --reverse, --skip nor --max-count. - makes get_revision() function the postprocessing phase: If reverse is given, wait for get_revision_1() to give everything that it would normally give, and then reverse it before consuming. If skip is given, skip that many before going further. If max is given, stop when we gave out that many. Now that we are about to return one positive commit, mark the parents of that commit to be potential boundaries before returning, iff we are doing the boundary processing. Return the commit. - After get_revision() finishes giving out all the positive commits, if we are doing the boundary processing, we look at the parents that we marked as potential boundaries earlier, see if they are really boundaries, and give them out. It loses more code than it adds, even when the new gc_boundary() function, which is purely for early optimization, is counted. Note that this patch is purely for eyeballing and discussion only. It breaks git-bundle's verify logic because the logic does not use BOUNDARY_SHOW flag for its internal computation anymore. After we correct it not to attempt to affect the boundary processing by setting the BOUNDARY_SHOW flag, we can remove BOUNDARY_SHOW from revision.h and use that bit assignment for the new CHILD_SHOWN flag.

The output from "symmetric diff", i.e. A...B, does not distinguish between commits that are reachable from A and the ones that are reachable from B.

Sometimes this is frustrating. This adds an output option, --left-right, to rev-list. rev-list --left-right A...B would show ones reachable from A prefixed with '<' and the ones reachable from B prefixed with '>'. When combined with --boundary, boundary commits (the ones marked with 'x' in the above picture) are shown with prefix '-', so you would see list that looks like this: git rev-list --left-right --boundary --pretty=oneline A...B >bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb 3rd on b >bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb 2nd on b <aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa 3rd on a <aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa 2nd on a -xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 1st on b -xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 1st on a Signed-off-by: Junio C Hamano <junkio@cox.net>

Incremental repack without -a essentially boils down to: rev-list --objects --unpacked --all | pack-objects $new_pack which picks up all loose objects that are still live and creates a new pack. This implements --unpacked=<existing pack> option to tell the revision walking machinery to pretend as if objects in such a pack are unpacked for the purpose of object listing. With this, we could say: rev-list --objects --unpacked=$active_pack --all | pack-objects $new_pack instead, to mean "all live loose objects but pretend as if objects that are in this pack are also unpacked". The newly created pack would be perfect for updating $active_pack by replacing it. Since pack-objects now knows how to do the rev-list's work itself internally, you can also write the above example by: pack-objects --unpacked=$active_pack --all $new_pack </dev/null Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-09-05revision.c: allow injecting revision parameters after setup_revisions().Libravatar Junio C Hamano1-0/+2
setup_revisions() wants to get all the parameters at once and then postprocesses the resulting revs structure after it is done with them. This code structure is a bit cumbersome to deal with efficiently when we want to inject revision parameters from the side (e.g. read from standard input). Fortunately, the nature of this postprocessing is not affected by revision parameters; they are affected only by flags. So it is Ok to do add_object() after the it returns. This splits out the code that deals with the revision parameter out of the main loop of setup_revisions(), so that we can later call it from elsewhere after it returns.

2006-06-19Add "named object array" conceptLibravatar Linus Torvalds1-5/+7
We've had this notion of a "object_list" for a long time, which eventually grew a "name" member because some users (notably git-rev-list) wanted to name each object as it is generated. That object_list is great for some things, but it isn't all that wonderful for others, and the "name" member is generally not used by everybody. This patch splits the users of the object_list array up into two: the traditional list users, who want the list-like format, and who don't actually use or want the name. And another class of users that really used the list as an extensible array, and generally wanted to name the objects. The patch is fairly straightforward, but it's also biggish. Most of it really just cleans things up: switching the revision parsing and listing over to the array makes things like the builtin-diff usage much simpler (we now see exactly how many members the array has, and we don't get the objects reversed from the order they were on the command line). One of the main reasons for doing this at all is that the malloc overhead of the simple object list was actually pretty high, and the array is just a lot denser. So this patch brings down memory usage by git-rev-list by just under 3% (on top of all the other memory use optimizations) on the mozilla archive. It does add more lines than it removes, and more importantly, it adds a whole new infrastructure for maintaining lists of objects, but on the other hand, the new dynamic array code is pretty obvious. The change to builtin-diff-tree.c shows a fairly good example of why an array interface is sometimes more natural, and just much simpler for everybody.
