2006-05-03Fix "git-log --parents" breakage post v1.3.0Linus Torvalds
Post 1.3.0 "git log" forgets to list parent commits on the first line when --parents is given. git-cvsserver relied on it. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-04-18Log message printout cleanups (#3): fix --pretty=onelineLinus Torvalds
This option is very special, since pretty_print_commit() will _remove_ the newline at the end of it, so we want to have an extra separator between the things. I added a honking big comment this time, so that (a) I don't forget this _again_ (I broke "oneline" several times during this printout cleanup), and so that people can understand _why_ the code does what it does. Now, arguably the alternate fix is to always have the '\n' at the end in pretty-print-commit, but git-rev-list depends on the current behaviour (but we could have git-rev-list remove it, whatever). With the big comment, the code hopefully doesn't get broken again. And now things like git log --pretty=oneline --cc --patch-with-stat works (even if that is admittedly a totally insane combination: if you want the patch, having the "oneline" log format is just crazy, but hey, it _works_. Even insane people are people). Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-04-18Log message printout cleanups (#2)Linus Torvalds
Here's a further patch on top of the previous one with cosmetic improvements (no "real" code changes, just trivial updates): - it gets the "---" before a diffstat right, including for the combined merge case. Righ now the logic is that we always use "---" when we have a diffstat, and an empty line otherwise. That's how I visually prefer it, but hey, it can be tweaked later. - I made "diff --cc/combined" add the "---/+++" header lines too. The thing won't be mistaken for a valid diff, since the "@@" lines have too many "@" characters (three or more), but it just makes it visually match a real diff, which at least to me makes a big difference in readability. Without them, it just looks very "wrong". I guess I should have taken the filename from each individual entry (and had one "---" file per parent), but I didn't even bother to try to see how that works, so this was the simple thing. With this, doing a git log --cc --patch-with-stat looks quite readable, I think. The only nagging issue - as far as I'm concerned - is that diffstats for merges are pretty questionable the way they are done now. I suspect it would be better to just have the _first_ diffstat, and always make the merge diffstat be the one for "result against first parent". 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>
2006-04-16Fixes for option parsingLinus Torvalds
Make sure "git show" always show the header, regardless of whether there is a diff or not. Also, make sure "always_show_header" actually works, since generate_header only tested it in one out of three return paths.

2006-04-16log/whatchanged/show - log formatting cleanup.Junio C Hamano
This moves the decision to print the log message, while diff options are in effect, to log-tree. It gives behaviour closer to the traditional one. Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-04-15Common option parsing for "git log --diff" and friendsLinus Torvalds
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.

2006-04-09log-tree: separate major part of diff-tree.Junio C Hamano
This separates out the part that deals with one-commit diff-tree (and --stdin form) into a separate log-tree module. There are two goals with this. The more important one is to be able to make this part available to "git log --diff", so that we can have a native "git whatchanged" command. Another is to simplify the commit log generation part simpler. Signed-off-by: Junio C Hamano <junkio@cox.net>
