branching: merge with stable

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)

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.

split: make sure hg split preserve the phase of splitting cset (issue6048) Before this patch, while splitting we were not taking the phase of splitting cset into account. By default new commits would have draft changes. As we know there can two possible phases i.e draft and secret in rewriting csets thing, so this adds the handling of secret phase (as default is draft) Changes in test file reflect the added behaviour.

split: add tests which demonstrate the issue6048 Next patch will fix this issue.

evolve: fix the broken behaviour on div resolution in relocation case In content divergence resolution, I see that when "relocationreq" is True which means both the cset are on different parent and relocation is required. In this case when "divergent" is the one who is behind the "other" cset in DAG, we swap them. At this point one thing we missed is to update the evolvestate['divergent']. Because of this in continue case we didn't get the right value of obsmarkers creation. In this patch I added the code to update the evolvestate when we swap them. Now as we know "divergent" and "other" can be swapped in some cases, it is better to store the intial divergent separately in evolvestate which is evolvestate['orig-divergent'] and later this value is used to update the evolvestate['replacements'] which is the track of revisions which has been resolved. Changes in tests demonstrate the fixed behaviour.

evolve: change in a test which demonstrate divergence resolution can break This patch just add "--any" flag to "hg evolve --content-divergent" in a test and changed output reflect that there is something which is not handled correctly. After looking into code I found that it is because of using a evolvestate value which is not updated i.e evolvestate['divergent'] Next patch will fix this problem.

tests: update the title of a test as it's not what it says I see that this test has conflict in relocation and in merging also. We do have a test for the case when only relocation leads to conflict.

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

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

branching: overwrite broken merge with a correct one Thanks goes to Anton Shestakov for spotting and fixing this.

obshistory: omit keyword arguments with default values in patch.diffui() calls d4c9eebdd72d made that function not take "relroot" and "prefix" anymore, and instead expect "pathfn". These two chunks of code in this patch simply generate patches for obslog -p and they broke because they tried to provide default values for "prefix" and "relroot" for no apparent reason (and also for "changes"). Let's instead rely on defaults of patch.diffui().
