2007-11-16Fix rev-list when showing objects involving submodulesLibravatar Linus Torvalds1-2/+9
The function mark_tree_uninteresting() assumed that the tree entries are blob when they are not trees. This is not so. Since we do not traverse into submodules (yet), the gitlinks should be ignored. In general, we should try to start moving away from using the "S_ISLNK()" like things for internal git state. It was a mistake to just assume the numbers all were same across all systems in the first place. This implementation converts to the "object_type", and then uses a case statement.

2007-10-15Fix embarrassing "git log --follow" bugLibravatar Linus Torvalds1-2/+2
It turns out that I completely broke "git log --follow" with my recent patch to revision.c ("Fix revision log diff setup, avoid unnecessary diff generation", commit b7bb760d5ed4881422673d32f869d140221d3564). Why? Because --follow obviously requires the diff machinery to function, exactly the same way pickaxe does. So everybody is away right now, but considering that nobody even noticed this bug, I don't think it matters. But for the record, here's the trivial one-liner fix (well, two, since I also fixed the comment). Because of the nature of the bug, if you ask for patches when following (which is one of the things I normally do), the bug is hidden, because then the request for diff output will automatically also enable the diffs themselves. So while "git log --follow <filename>" didn't work, adding a "-p" magically made it work again even without this fix.

2007-09-29Fix revision log diff setup, avoid unnecessary diff generationLibravatar Linus Torvalds1-2/+8
We used to incorrectly start calculating diffs whenever any argument but '-z' was recognized by the diff options parsing. That was bogus, since not all arguments result in diffs being needed, so we just waste a lot of time and effort on calculating diffs that don't matter. This actually also fixes another bug in "git log". Try this: git log -C and notice how it prints an extra empty line in between log entries, even though it never prints the actual diff (because we didn't ask for any diff format, so the diff machinery never prints anything). With this patch, that bogus empty line is gone, because "revs->diff" is never set. So this isn't just a "wasted time and effort" issue, it's also a slight semantic fix.

2007-09-15revision walker: --cherry-pick is a limited operationLibravatar Johannes Schindelin1-0/+1
We used to rely on the fact that cherry-pick would trigger the code path to set limited = 1 in handle_commit(), when an uninteresting commit was encountered. However, when cherry picking between two independent branches, i.e. when there are no merge bases, and there is only linear development (which can happen when you cvsimport a fork of a project), no uninteresting commit will be encountered. So set limited = 1 when --cherry-pick was asked for. Noticed by Martin Bähr. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2007-08-31Make "git-log --" without paths behave the same as "git-log" without --Libravatar Junio C Hamano1-1/+2
"git log" family of commands, even when run from a subdirectory, do not limit the revision range with the current directory as the path limiter, but with double-dash without any paths after it, i.e. "git log --" do so. It was a mistake to have a difference between "git log --" and "git log" introduced in commit ae563542bf10fa8c33abd2a354e4b28aca4264d7 (First cut at libifying revlist generation).

2007-08-19Don't allow combination of -g and --reverse as it doesn't workLibravatar Shawn O. Pearce1-0/+3
The --walk-reflogs logic and the --reverse logic are completely incompatible with one another. Attempting to use both at the same time leads to confusing results that sometimes violates the user's formatting options or ignores the user's request to see the reflog message and timestamp. Unfortunately the implementation of both of these features is glued onto the side of the revision walking machinary in such a way that they are probably not going to be easy to make them compatible with each other. Rather than offering the user confusing results we are better off bailing out with an error message until such a time as the implementations can be refactored to be compatible.

2007-07-23Teach revision machinery about --no-walkLibravatar Johannes Schindelin1-0/+8
The flag "no_walk" is present in struct rev_info since a long time, but so far has been in use exclusively by "git show". With this flag, you can see all your refs, ordered by date of the last commit: $ git log --abbrev-commit --pretty=oneline --decorate --all --no-walk which is extremely helpful if you have to juggle with a lot topic branches, and do not remember in which one you introduced that uber debug option, or simply want to get an overview what is cooking. (Note that the "git log" invocation above does not output the same as $ git show --abbrev-commit --pretty=oneline --decorate --all --quiet since "git show" keeps the alphabetic order that "--all" returns the refs in, even if the option "--date-order" was passed.)

2007-06-22Finally implement "git log --follow"Libravatar Linus Torvalds1-1/+3
Ok, I've really held off doing this too damn long, because I'm lazy, and I was always hoping that somebody else would do it. But no, people keep asking for it, but nobody actually did anything, so I decided I might as well bite the bullet, and instead of telling people they could add a "--follow" flag to "git log" to do what they want to do, I decided that it looks like I just have to do it for them.. The code wasn't actually that complicated, in that the diffstat for this patch literally says "70 insertions(+), 1 deletions(-)", but I will have to admit that in order to get to this fairly simple patch, you did have to know and understand the internal git diff generation machinery pretty well, and had to really be able to follow how commit generation interacts with generating patches and generating the log. So I suspect that while I was right that it wasn't that hard, I might have been expecting too much of random people - this patch does seem to be firmly in the core "Linus or Junio" territory. To make a long story short: I'm sorry for it taking so long until I just did it. I'm not going to guarantee that this works for everybody, but you really can just look at the patch, and after the appropriate appreciative noises ("Ooh, aah") over how clever I am, you can then just notice that the code itself isn't really that complicated. All the real new code is in the new "try_to_follow_renames()" function. It really isn't rocket science: we notice that the pathname we were looking at went away, so we start a full tree diff and try to see if we can instead make that pathname be a rename or a copy from some other previous pathname. And if we can, we just continue, except we show *that* particular diff, and ever after we use the _previous_ pathname. One thing to look out for: the "rename detection" is considered to be a singular event in the _linear_ "git log" output! That's what people want to do, but I just wanted to point out that this patch is *not* carrying around a "commit,pathname" kind of pair and it's *not* going to be able to notice the file coming from multiple *different* files in earlier history. IOW, if you use "git log --follow", then you get the stupid CVS/SVN kind of "files have single identities" kind of semantics, and git log will just pick the identity based on the normal move/copy heuristics _as_if_ the history could be linearized. Put another way: I think the model is broken, but given the broken model, I think this patch does just about as well as you can do. If you have merges with the same "file" having different filenames over the two branches, git will just end up picking _one_ of the pathnames at the point where the newer one goes away. It never looks at multiple pathnames in parallel. And if you understood all that, you probably didn't need it explained, and if you didn't understand the above blathering, it doesn't really mtter to you. What matters to you is that you can now do git log -p --follow builtin-rev-list.c and it will find the point where the old "rev-list.c" got renamed to "builtin-rev-list.c" and show it as such.

This uses diff-tree --quiet machinery to terminate the internal diff-tree between a commit and its parents via revs.pruning (not revs.diffopt) as soon as we find enough about the tree change. With respect to the optionally given pathspec, we are interested if the tree of commit is identical to the parent's, only adds new paths to the parent's, or there are other differences. As soon as we find out that there is one such other kind of difference, we do not have to compare the rest of the tree. Because we do not call standard diff_addremove/diff_change, we instruct the diff-tree machinery to stop early by setting has_changes when we say we found the trees to be different.

2007-03-06revision walker: Fix --boundary when limitedLibravatar Junio C Hamano1-114/+94
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.
