evolve: preserve compatibility for hg < 4.8 versions This patch make sure evolve don't break if user using a version of hg before this 7694b685bb10 patch on hg-committed.

evolve: warn user if cset desc is being lost In public divergence when merging results in same as public cset, we only create markers to solve the divergence i.e. [(public, (other,))] In this case if other cset had a desc which was different from public that will be lost. So this print out a warning message to user that desc of non-public cset is being lost. Changes in test files reflect the added behaviour.

changelog: mention latest improvement

stack: make @ (current) more important than $ (some sort of unstable) Base is still ^ even if it's currently checked out.

stack: show content and phase divergent state and symbol Replacing ' ' with '-' is just for color labels.

stack: handle external-children just like other states This also fixes color labels: previously when external-children was combined with another state, --color=debug would show something like: [topic.stack.index topic.stack.index.current - external-children|s4] Now there is a separate label for each state.

stack: optimize revset used for stack --children Since that option needs to exclude changesets on the current stack, let's just use stack.revs (that are cached) for that and skip branch() or topic() revset. st.revs[0] is the stack base, we don't consider it actual part of stack.

stack: rename unstable -> orphan That's the only instability stack can currently show, but it's about to show more and showing "unstable" for one type of instability just isn't good.

evolvecmd: compatibility with older geteffectflag() that took a tuple Before bae6f1418a95 the function took a tuple of 2 arguments instead of these 2 arguments directly.

obshistory: remove unused geteffectflag(), it's been in core since 4.4

compat: remove old vocabulary change fallbacks Mercurial 4.4 (minimal hg version evolve currently supports) already uses the new names and in fact has deprecation warnings saying that 4.4 is the last version of Mercurial to support the old names.

branching: merge with stable

evolve: fix a typo from directory to dirty

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.

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.

evolve: add tests of relocation case in public divergence These tests cover the cases when "other" is behind the "public" one and we would have to relocate "other" here. It covers all the conflicting and non-conflicting cases.
