Provide a way to flush git-diff-tree's output

2006-05-18T07:25:50Z

Gitk wants to use git-diff-tree as a filter to tell it which ids from a given list affect a set of files or directories. We don't want to fork and exec a new git-diff-tree process for each batch of ids, since there could be a lot of relatively small batches. For example, a batch could contain as many ids as fit in gitk's headline display window, i.e. 20 or so, and we would be processing a new batch every time the user scrolls that window. The --stdin flag to git-diff-tree is suitable for this, but the main difficulty is that the output of git-diff-tree gets buffered and doesn't get sent until the buffer is full. This provides a way to get git-diff-tree to flush its output buffers. If a blank line is supplied on git-diff-tree's standard input, it will flush its output buffers and then accept further input.

Log message printout cleanups

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 Signed-off-by: Junio C Hamano

Split init_revisions() out of setup_revisions()

2006-04-16T06:46:36Z

Merging all three option parsers related to whatchanged is unarguably the right thing, but the fallout was too big to scare me away. Let's try it once again, but once step at time. This splits out init_revisions() call from setup_revisions(), so that the callers can set different defaults to match the traditional benaviour. The rev-list command is still broken in a big way, which is the topic of next step. Signed-off-by: Junio C Hamano

Common option parsing for "git log --diff" and friends

2006-04-15T04:56:55Z

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.

tree-diff: do not assume we use only one pathspec

2006-04-10T23:45:19Z

The way tree-diff was set up assumed we would use only one set of pathspec during the entire life of the program. Move the pathspec related static variables out to diff_options structure so that we can filter commits with one set of paths while show the actual diffs using different set of paths. I suspect this breaks blame.c, and makes "git log paths..." to default to the --full-diff, the latter of which is dealt with the next commit. Signed-off-by: Junio C Hamano

log-tree: separate major part of diff-tree.

2006-04-09T08:35:13Z

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

This replaces occurences of "blob", "commit", "tag", and "tree", where they're really used as type specifiers, which we already have defined global constants for. Signed-off-by: Peter Eriksen Signed-off-by: Junio C Hamano

diff-tree: do not default to -c

Marco says it breaks qgit.
