evolve: remove todo markers from a test which has been fixed

next: clarify tests related to `commands.update.check` test This clarify the test and help understand the next changeset.

stack: simplify phasecache checks in _stackcandidates()

evolve: fix divergence resolution when not merging a descendant In divergence resolution, when we merge other cset with divergent one we pass a `mergeancestor` arg to merge.update() and before this patch we were passing `mergeancestor` as True in every case. But it should be True only when we are merging a descendant onto an ancestor. When mergeancestor is True it does two things: 1) allows the merge if the destination is the same as the parent of the ctx (so we can use graft to copy commits) 2) informs update that the incoming changes are newer than the destination so it doesn't prompt about "remote changed foo which local deleted". So this patch change it to pass `mergeancestor` as True only when it is required. And changes in test file shows that it wasn't prompting either in those cases when it should (acc. to 2nd point) Test written by Pierre-Yves David, based the one updated in 5dbaabfe2c59.

test: fix a phase divergence test case to actually not contains conflict The previous test case had a conflict, but that conflict is currently not raise by phase divergence resolution. This is an independent bug to solve.

tests: use current instability names everywhere

test: apply unstability resolution to `test-unstability-resolution-result.t` The test cases in this file probably deserved to be dispatched in other more thematic test file.

test: rename and clarify content of test-unstable-content-divergent.t The troubles → instabilities renaming was not applied here.

test: rename and clarify content of test-unstable-orphan.t The troubles → instabilities renaming was not applied here.

evolve: refactor the code which swap two nodes (in divergence resolution) I see that we are using the code to swap the "divergent" and "other" node; and updating the evolvestate accordingly at many places in divergence resolution. This patch extract that code to a function. Although I don't have strong opinion on this patch. It's a volunteered patch to remove some redundancy.

evolve: remove tmpctx arg from _resolvephasedivergent() Before this patch, in _resolvephasedivergent() function we were passing an optional argument "tmpctx" which was used to store a rebased version of bumped if required. But for sake of simplicity we can achieve the same results even without passing this "tmpctx" into that function. No changes in test files demonstrate that this patch don't break anything.

doc: clarify _resolvephasedivergent role and constraint Small documentation patch before larger changes.

branching: merge with stable

evolve: unindent some lines caught by flake8 The message was: "E117 over-indented".

obsexchange: avoid importing io/StringIO module with a different name Since we're not interested in the whole module, let's shorten the imports and aviod the lint warnings. Otherwise pep8-naming complains: - import io as StringIO: N812 lowercase imported as non lowercase - import StringIO as io: N813 camelcase imported as lowercase

evolve: remove unused StringIO import

compat: add support for new arg name in memfilectx.__init__ This makes us compatible with 550a172a603b (memctx: rename constructor argument "copied" to "copysource" (API), 2019-03-19).

topic: make topics compatible with branchmap refactor See https://phab.mercurial-scm.org/D5290

evolve: compat patch to fix broken evolve obsdiscovery This patch preserve the compatibility for the changes upstreamed by e5ece0f46b40 in hg-committed.

tests: add obslog output to some tests for divergence resolution As suggested by Boris Feld.

tests: add tests for divergence resolution with split+amend As suggested by Boris Feld. G: changed tests/test-evolve-phase-divergence.t

test: use 'split' instead of 'splitted' in the tests

evolve: drop the "computing new diff message" for phase-divergence Future code update will remove this message, dropping it early clarify the future diff.

evolve: clarify output when phase-divergence resolution results in no change I found it pretty confusing that it said "committed as abcd1234" when no commit was created.

tests: reduce dependence on previous tests for setup The tests in test-evolve-phase-divergence.t built on each other for no good reason, which makes the tests hard to modify and hard to read. This patch cleans up some of them. We should clean up the rest too, but the rest won't matter for my next patch, so I haven't bothered.

topicmap: add compatibility for branchcache that now uses self._entries

evolve: fix over-idented block

tests: create "private" repository in already-updated state I'm going to add more copies of the repo and it's easier to work with the repo if it's already been updated.

touch: use action "touch", not "<function touch at ...>", in precheck I just got this message: abort: cannot <function touch at 0x7fde174b69b0> public changesets: f177c51ae98f It has been this way since 1b7b9acda2a9 (touch: use precheck to validate revision, 2017-07-23).

prune: use action "prune", not "touch", in precheck We have been using "touch" since 06ee4ec88190 (prune: use precheck to validate revision, 2017-07-23). That commit modified the tests, so it kind seemed intentional, but I suspect it was still just an oversight.

evolve: test a common case of public divergence evolve: in pubdiv, handle the case when public branch is behind the mutable In public divergence, when public branch is behind the mutable one the behaviour that this patch added is that we relocate the draft one to public side. This should be fine in most case, but might be an issue in some other (eg, when the draft side of the divergence is rebase away from ancestors it relies on.) Test written by Pierre-Yves David <pierre-yves.david@octobus.net>

evolve: add condition in case of pubdiv to not swap the two div csets In public divergence, we have pinned the public cset to the local side when merge is performed. And in divergence resolution implementation divergent cset is the one who is kept at the local side, so to say this in one line: we have pinned public cset to the divergent side. However, in some cases we need to swap the "divergent" and "other" but we can't swap them in case of public divergence as thought would cause an error because of not being able to relocate public cset.

evolve: add logic to handle a particular case in divergence resolution Case is: In content divergence, to check if the two csets are on different parent or same parent what we do is find gca of the two csets and then compare it with the singlesuccessors of two csets's parents. Now, if gca is same as singlesuccessors of both the csets then we conclude that both are on the same parent which is not totally correct as it is possible that both the parents of two csets are obsolete with a single successor. This patch adds the logic to cover the above metioned case correctly, deciding the part when we need to relocate a cset to other side while resolving the stack of divergent csets. Changes in test file demonstrate that before this patch we were not doing it right because it should have relocated every node to other side instead of just relocating the first one from the stack.

evolve: add a test reflecting wrong behaviour of content-div resolution This patch shows that currently the case when stack of divergent csets have different parents is not handled correctly. For a stack of csets which has different parent, right behaviour is to relocate every node before performing merge but present implementation only relocate first cset in the stack and skip relocation for the rest of csets, this is not what we expect it to do. Next patch will be about fixing this issue.

compat: add support for new arg name in memfilectx.__init__ This makes us compatible with 550a172a603b (memctx: rename constructor argument "copied" to "copysource" (API), 2019-03-19).

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.

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)
