scmutil: document matcher argument of movedirstate() Differential Revision: https://phab.mercurial-scm.org/D6120

uncommit: move _movedirstate() to scmutil for reuse The function should be applicable generically when moving from one commit to another. I'll try to add more callers when I find time. I'm not convinced it's handling all the cases correctly, but we should have a generic function for this kind of operation, so I think it belongs somewhere in core (not in the uncommit extension).

copies: remove dependency on scmutil by directly using match.exact() I want to add a dependency from scmutil.copies(), so I need to remove this dependency first. Differential Revision: https://phab.mercurial-scm.org/D6118

uncommit: convert _fixdirstate() into _movedirstate() _fixdirstate() already also updates to the given commit, so let's rename it to _movedirstate(). Also update the documentation and drop the unnecessary "curctx" argument, since that should always be repo['.']. Differential Revision: https://phab.mercurial-scm.org/D6117

updatecaches: also warm the tags caches Resolving any name requires the tags cache to be warm. We make sure that `hg debugupdatecache` warm the tag cache entry too.

updatecaches: also warm revbranchcache for filtered revisions We are in the "full" case, so we better warm everything we can.

copies: handle a case when both merging csets are not descendant of merge base This patch fix the behaviour of fullcopytracing algorithm in the case when both the merging csets are not the descendant of merge base. Although it seems to be the rare case when both the csets are not descendant of merge base. But it can be seen in most of cases of content-divergence in evolve extension, where merge base is the common predecessor. Previous patch added a test where this algorithm can fail to continue because of an assumption that only one of the two csets can be dirty. This patch fix that error. For refrence I suggest you to look into the previous discussion held on a patch sent by Pulkit: https://phab.mercurial-scm.org/D3896 Differential Revision: https://phab.mercurial-scm.org/D5963

copies: add test that makes both the merging csets dirty and fails This patch is a part of series which is about the case when both the merging csets are not descendant of merge base. The existing code assumes if c1 is dirty there shouldn't be any partial copies from c2 i.e both2['incomplete'] and same for c2, if c2 is dirty both1['incomplete'] should be empty, but this is not the right assumption. Now as we know we can have both c1 and c2 dirty at the same time, it is possible that c1 is dirty and both2['incomplete'] has some value. Or if c2 is dirty and both1['incomplete'] has some value. Added test shows that because of this assumption it could fail. Differential Revision: https://phab.mercurial-scm.org/D5962

copies: add test that makes both the merging csets dirty and run w/o error This series of patches is to cover a case in fullcopytracing algorithms where both the merging csets are not descendant of merge base. In this algorithm we call a merging cset "dirty" if that cset is not the descendant of merge base. That said, added test in this patch cover case when both the merging csets are "dirty". Actually this case of "both dirty" was encountered by Pulkit when he was working on content-divergence where it is possible that both the csets are not descendant of merging base. For reference you can look into: https://phab.mercurial-scm.org/D3896 As this test run fine without any error and correctly traced the copies, I added this test to make sure that it doesn't break even after I will modify some code in next patches to fix an error. Next patch adds the tests where this algorithm throws an error for the same case of "both dirty". Differential Revision: https://phab.mercurial-scm.org/D5961
