2007-01-20Teach the revision walker to walk by reflogs with --walk-reflogsLibravatar Johannes Schindelin1-0/+2

2006-12-26Teach log family --encodingLibravatar Junio C Hamano1-0/+1
Updated commit objects record the encoding used in their encoding header. This updates the log family to reencode it into the encoding specified in i18n.commitencoding (or the default, which is "utf-8") upon output. To force a specific encoding that is different, log family takes command line flag --encoding=<encoding>; giving --encoding=none entirely disables the reencoding and lets you view log messges in their original encoding.

2006-12-19Revert "Make left-right automatic."Libravatar Junio C Hamano1-1/+0
This reverts commit 5761231975ceffa531d86d9bab0f9a9a370674f6. Feeding symmetric difference to gitk is so useful, and it is the same for other graphical Porcelains. Rather than forcing them to pass --no-left-right, making it optional. Noticed and reported by Jeff King.
2006-12-17Make left-right automatic.Libravatar Junio C Hamano1-0/+1
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). Just in case, a new option --no-left-right is provided to defeat this, but I do not know if it would be useful. Signed-off-by: Junio C Hamano <junkio@cox.net>

2006-12-17rev-list --left-rightLibravatar Junio C Hamano1-0/+1
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. In this picture, such a symmetric diff includes commits marked with a and b. x---b---b branch B / \ / / . / / \ o---x---a---a branch A However, you cannot tell which ones are 'a' and which ones are 'b' from the output. 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>

Unfortunately, to make --and, --not and other grep boolean expressions useful, as in: # Things written by Junio committed and by Linus and log # does not talk about diff. git log --author=Junio --and --committer=Linus \ --grep-not --grep=diff we will need to do another round of built-in grep core enhancement, because grep boolean expressions are designed to work on one line at a time.

2006-09-07pack-objects --unpacked=<existing pack> option.Libravatar Junio C Hamano1-1/+5
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.

2006-07-28Call setup_git_directory() earlyLibravatar Linus Torvalds1-1/+1
Any git command that expects to work in a subdirectory of a project, and that reads the git config files (which is just about all of them) needs to make sure that it does the "setup_git_directory()" call before it tries to read the config file. This means, among other things, that we need to move the call out of "init_revisions()", and into the caller. This does the mostly trivial conversion to do that.

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.

2006-06-16gitweb.cgi history not shownLibravatar Linus Torvalds1-0/+1
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>

On Sun, 16 Apr 2006, Junio C Hamano wrote: > > In the mid-term, I am hoping we can drop the generate_header() > callchain _and_ the custom code that formats commit log in-core, > found in cmd_log_wc(). 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 uses the "--no-walk" flag that I never actually implemented (but I'm sure I mentioned it) to make "git show" be essentially the same thing as "git whatchanged --no-walk". It just refuses to add more interesting parents to the revision walking history, so you don't actually get any history, you just get the commit you asked for. I was going to add "--no-walk" as a real argument flag to git-rev-list too, but I'm not sure anybody actually needs it. Although it might be useful for porcelain, so I left the door open.

2006-04-14Common option parsing for "git log --diff" and friendsLibravatar Linus Torvalds1-1/+20
This basically does a few things that are sadly somewhat interdependent, and nontrivial to split out - get rid of "struct log_tree_opt" The fields in "log_tree_opt" are moved into "struct rev_info", and all users of log_tree_opt are changed to use the rev_info struct instead. - add the parsing for the log_tree_opt arguments to "setup_revision()" - make setup_revision set a flag (revs->diff) if the diff-related arguments were used. 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.

2006-04-08Make "--parents" logs also be incrementalLibravatar Linus Torvalds1-0/+1
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.

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.
