* Add custom subject prefix support to format-patch (take 3)Robin H. Johnson2007-04-11
| | | | | | | | | | | Add a new option to git-format-patch, entitled --subject-prefix that allows control of the subject prefix '[PATCH]'. Using this option, the text 'PATCH' is replaced with whatever input is provided to the option. This allows easily generating patches like '[PATCH 2.6.21-rc3]' or properly numbered series like '[-mm3 PATCH N/M]'. This patch provides the implementation and documentation. Signed-off-by: Robin H.

| * revision traversal: retire BOUNDARY_SHOWJunio C Hamano2007-03-06
| | | | | | | | | | | | | | | | | | | | | | 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. The flag is still useful but it is local to the git-bundle, so it is renamed to PREREQ_MARK. Signed-off-by: Junio C Hamano <junkio@cox.net>

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | When using symmetric differences, I think the user almost always would want to know which side of the symmetry each commit came from. So this removes --left-right option from the command line, and turns it on automatically when a symmetric difference is used ("git log --merge" counts as a symmetric difference between HEAD and MERGE_HEAD).

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>

* pack-objects --unpacked=<existing pack> option.Junio C Hamano2006-09-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* revision.c: allow injecting revision parameters after setup_revisions().Junio C Hamano2006-09-05
| | | | | | | | | | | | | | | | | | 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.

* Add "named object array" conceptLinus Torvalds2006-06-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* gitweb.cgi history not shownLinus Torvalds2006-06-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This does: - add a "rev.simplify_history" flag which defaults to on - it turns it off for "git whatchanged" (which thus now has real semantics outside of "git log") - it adds a command line flag ("--full-history") to turn it off for others (ie you can make "git log" and "gitk" etc get the semantics if you want to. Now, just as an example of _why_ you really really really want to simplify history by default, apply this patch, install it, and try these two command lines: gitk --full-history -- git.c gitk -- git.c and compare the output. So with this, you can also now do git whatchanged -p -- gitweb.cgi git log -p --full-history -- gitweb.cgi and it will show the old history of gitweb.cgi, even though it's not relevant to the _current_ state of the name "gitweb.cgi" NOTE NOTE NOTE! It will still actually simplify away merges that didn't change anything at all into either child. That creates these bogus strange discontinuities if you look at it with "gitk" (look at the --full-history gitk output for git.c, and you'll see a few strange cases). So the whole "--parent" thing ends up somewhat bogus with --full-history because of this, but I'm not sure it's worth even worrying about. I don't think you'd ever want to really use "--full-history" with the graphical representation, I just give it as an example exactly to show _why_ doing so would be insane. I think this is trivial enough and useful enough to be worth merging into the stable branch. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

Ok, this was nastier than expected, just because the dependencies between the different log-printing stuff were absolutely _everywhere_, but here's a patch that does exactly that. The patch is not very easy to read, and the "--patch-with-stat" thing is still broken (it does not call the "show_log()" thing properly for merges). That's not a new bug. In the new world order it _should_ do something like if (rev->logopt) show_log(rev, rev->logopt, "---\n"); but it doesn't. I haven't looked at the --with-stat logic, so I left it alone. That said, this patch removes more lines than it adds, and in particular, the "cmd_log_wc()" loop is now a very clean: while ((commit = get_revision(rev)) != NULL) { log_tree_commit(rev, commit); free(commit->buffer); commit->buffer = NULL; } so it doesn't get much prettier than this. All the complexity is entirely hidden in log-tree.c, and any code that needs to flush the log literally just needs to do the "if (rev->logopt) show_log(...)" incantation. I had to make the combined_diff() logic take a "struct rev_info" instead of just a "struct diff_options", but that part is pretty clean. This does change "git whatchanged" from using "diff-tree" as the commit descriptor to "commit", and I changed one of the tests to reflect that new reality. Otherwise everything still passes, and my other tests look fine too. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

This allows "git log" to decide whether it wants to show diffs or not. - make setup_revision() also initialize the diffopt part of rev_info (which we had from before, but we just didn't initialize it) - make setup_revision() do all the "finishing touches" on it all (it will do the proper flag combination logic, and call "diff_setup_done()") Now, that was the easy and straightforward part. The slightly more involved part is that some of the programs that want to use the new-and-improved rev_info parsing don't actually want _commits_, they may want tree'ish arguments instead. That meant that I had to change setup_revision() to parse the arguments not into the "revs->commits" list, but into the "revs->pending_objects" list. Then, when we do "prepare_revision_walk()", we walk that list, and create the sorted commit list from there. This actually cleaned some stuff up, but it's the less obvious part of the patch, and re-organized the "revision.c" logic somewhat. It actually paves the way for splitting argument parsing _entirely_ out of "revision.c", since now the argument parsing really is totally independent of the commit walking: that didn't use to be true, since there was lots of overlap with get_commit_reference() handling etc, now the _only_ overlap is the shared (and trivial) "add_pending_object()" thing. However, I didn't do that file split, just because I wanted the diff itself to be smaller, and show the actual changes more clearly. If this gets accepted, I'll do further cleanups then - that includes the file split, but also using the new infrastructure to do a nicer "git diff" etc. Even in this form, it actually ends up removing more lines than it adds. It's nice to note how simple and straightforward this makes the built-in "git log" command, even though it continues to support all the diff flags too. It doesn't get much simpler that this. I think this is worth merging soonish, because it does allow for future cleanup and even more sharing of code. However, it obviously touches "revision.c", which is subtle. I've tested that it passes all the tests we have, and it passes my "looks sane" detector, but somebody else should also give it a good look-over.

* Make "--parents" logs also be incrementalLinus Torvalds2006-04-08
| | | | | | | | | | | | | | | | | | | The parent rewriting feature caused us to create the whole history in one go, and then simplify it later, because of how rewrite_parents() had been written. However, with a little tweaking, it's perfectly possible to do even that one incrementally. Right now, this doesn't really much matter, because every user of "--parents" will probably generally _also_ use "--topo-order", which will cause the old non-incremental behaviour anyway. However, I'm hopeful that we could make even the topological sort incremental, or at least _partially_ so (for example, make it incremental up to the first merge). In the meantime, this at least moves things in the right direction, and removes a strange special case.

* Move "--parent" parsing into generic revision.c library codeLinus Torvalds2006-03-31
| | | | | | | | | Not only do we do it in both rev-list.c and git.c, the revision walking code will soon want to know whether we should rewrite parenthood information or not. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
* rev-list --boundaryJunio C Hamano2006-03-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | With the new --boundary flag, the output from rev-list includes the UNINTERESING commits at the boundary, which are usually not shown. Their object names are prefixed with '-'. For example, with this graph: C side / A---B---D master You would get something like this: $ git rev-list --boundary --header --parents side..master D B tree D^{tree} parent B ... log message for commit D here ... \0-B A tree B^{tree} parent A ... log message for commit B here ... \0 Signed-off-by: Junio C Hamano <junkio@cox.net>
* rev-lib: Make it easy to do rename tracking (take 2)Fredrik Kuivinen2006-03-10
| | | | | | | | | | | | prune_fn in the rev_info structure is called in place of try_to_simplify_commit. This makes it possible to do rename tracking with a custom try_to_simplify_commit-like function. This commit also introduces init_revisions which initialises the rev_info structure with default values.

* git-log (internal): more options.Junio C Hamano2006-03-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This ports the following options from rev-list based git-log implementation: * -<n>, -n<n>, and -n <n>. I am still wondering if we want this natively supported by setup_revisions(), which already takes --max-count. We may want to move them in the next round. Also I am not sure if we can get away with not setting revs->limited when we set max-count. The latest rev-list.c and revision.c in this series do not, so I left them as they are. * --pretty and --pretty=<fmt>. * --abbrev=<n> and --no-abbrev. The previous commit already handles time-based limiters (--since, --until and friends). The remaining things that rev-list based git-log happens to do are not useful in a pure log-viewing purposes, and not ported: * --bisect (obviously). * --header. I am actually in favor of doing the NUL terminated record format, but rev-list based one always passed --pretty, which defeated this option. Maybe next round. * --parents. I do not think of a reason a log viewer wants this. The flag is primarily for feeding squashed history via pipe to downstream tools. Signed-off-by: Junio C Hamano <junkio@cox.net>
* Rip out merge-order and make "git log <paths>..." work again.Linus Torvalds2006-03-01
| | | | | | | | | | | | | | Well, assuming breaking --merge-order is fine, here's a patch (on top of the other ones) that makes git log <filename> actually work, as far as I can tell. I didn't add the logic for --before/--after flags, but that should be pretty trivial, and is independent of this anyway. Signed-off-by: Junio C Hamano <junkio@cox.net>
* git-rev-list libification: rev-list walkingLinus Torvalds2006-02-28
| | | | | | | | | | | | | This actually moves the "meat" of the revision walking from rev-list.c to the new library code in revision.h. It introduces the new functions void prepare_revision_walk(struct rev_info *revs); struct commit *get_revision(struct rev_info *revs); to prepare and then walk the revisions that we have.

* Splitting rev-list into revisions lib, end of beginning.Linus Torvalds2006-02-27
| | | | | | | This makes the rewrite easier to validate in that revision flag parsing and warlking part are now all in rev_info structure. Signed-off-by: Junio C Hamano <junkio@cox.net>
* First cut at libifying revlist generationLinus Torvalds2006-02-26
| | | | | | | | | | | | | | | | This really just splits things up partially, and creates the interface to set things up by parsing the command line. No real code changes so far, although the parsing of filenames is a bit stricter. In particular, if there is a "--", then we do not accept any filenames before it, and if there isn't any "--", then we check that _all_ paths listed are valid, not just the first one. The new argument parsing automatically also gives us "--default" and "--not" handling as in git-rev-parse.

* Include <limits.h> in commit.c for ULONG_MAX. Remove old "revision.h".Linus Torvalds2005-04-21

* Make the revision tracking track the object types too.Linus Torvalds2005-04-17
| | | | | This allows fsck to verify not just that an object exists, but also that it has the type it was expected to have.
