evolve: fix the dirstate after setting parents with dirty wdir (issue5930) Before this patch, during an interrupted evolve it can be confused about copies. This patch fix the dirstate when parents are changed using dirstate.setparents() with a dirty wdir. Changes in test file reflect the fixed behaviour.

evolve: add tests which shows evolve can get confused about copies (issue5930) This test demonstrate that an interrupted evolve can get confused about copies. Next patch will fix this.

test: include some documentation to describe the case briefly

split: use ui.configoverride to preserve phase while commiting As we need to preserve the phase of revision which is going to be splitted into multiple revision. This patch use ui.configoverrides to temporarily overwrite the phases.new-commit config option at the time of committing a new node.

branching: merge with stable

changelog: add entries for the recent fixes

evolve: make sure user can recover from conflict (issue6053) we make sure while continuing interrupted evolve it reach to right code This patch fix the issue6053 which is about falling evolve into unrecoverable state and this is how it call fall into it: If after some rewrite operations we reach to a point where resparent for two content divergent csets is obsolete and we hit a conflict in relocation, so now if you run `hg evolve --continue` after resolving the conflict: code execution would check if wdir parent is obsolete and run solveobswdp() rather than going to continueevolve() part and there we will hit by a "abort: outstanding uncommitted merge" And same for `--abort` or `--stop` flags. Changes in tests reflect the fixed behaviour.

evolve: add test which shows unrecoverable evolve state (issue6053)

evolve: add a test in pubdiv where only merging leads to conflict Added a test in public divergence where both the cset are on the different parent and no conflict in relocation but in merging.

evolve: cover continue case in pubdiv when merging results in same as public This patch is the part of a series which is adding support of public divergence resolution of the case when merging results in same as pubic cset. Changes made in this patch cover the --continue flag for the case: when we had conflicts in merging. Modified lines in previously added tests reflects the changed behaviour. Also added some additional tests. I guess I have covered every possbile case in test-evolve-public-content-divergent.t While reviewing, if you see any test missed please let me know. (I think there is one test missed that I will send as a follow-up)

evolve: handle a case in pubic-div when merging results in same as public In public divergence resolution, what we do is: 1) first apply content divergence resolution 2) then phase divergent resolution on resultant node of 1) case While doing case 1 it is possible that result of merging the two csets would have same changes as public one contains. And then processing the case 2 would create an empty commit which is not something we want to do. So this patch catch that same case when merging results in same as public cset and don't create a new node, instead to solve the divergence it just add a obsmarker from "other divergent" to "public divergent" i.e. [other, (public,)] Next patch will add the continue case handling for this same case. This patch also adds the tests for the different cases which are possible for the above mentioned case. There is test for continue case too which is broken in this patch and will be fixed in next patch.

evolve: rename npublicdiv to publicnode In next patches it would make more sense to use publicnode instead of npublicdiv.

evolve: in pubdiv resolution make sure that transaction get closed Before this patch it could be possible that transaction won't get closed if res is False in the pubic divergence resolution when continuing the hg evolve.

evolve: pin the public cset to local side in merging when solving public div While working on public divergence, I think it would be better to pin the public cset to local side of merge for understanding and handling the future cases without any ambiguity. Changes in tests reflect the changed behaviour.
