evolve: use merge.update() for resolving phase divergence Iterating over the manifest when tree manifests and narrowness is in play produces entries for paths outside the narrowspec that represent trees. For example, if the tests/ directory of the hg repo was not in the narrowspec (and the hg repo was using tree manifests, which it doesn't), then there would be a "tests/" entry in the manifest. The merge code deals with some of these cases. For example, it's valid to do a merge if only the local side changes directories outside the narrowspec. That allows rebasing a local commit onto a public commit that had changes to the excluded paths to work. However, _resolvephasedivergent() was iterating of the manifests, which resulted in crashes for some of our users when they tried to resolve phase-divergent commits (actually content-divergent commits that became phase-divergent after the intermediate rebase). We can fix that by relying on merge.update(), since that already handles this case.

evolve: compat patch for recordfilter change in mercurial This patch fix the broken things because of upstream changes in recordfilter() which is being used to select the hunks interactively. It fixes the test-uncommit-interactive.t by adding the compat layer. But for test-split.t I had to fix the tests manually. To make it more clear: splitting broke at evolve side because after that upstream change now interactive mode doesn't prompt "examine change to foo" if foo is mentioned explicitly using cli; and directly jumps to hunks selection prompt (well, only if there is any changes at hunks level) And the main issue is when file which is explicitly mentioned has no changes at hunk level (for e.g copy, rename, mode change, empty new file), because in that case you don't have any control on selection of that file and it would be included automatically in first cycle of interactive selection. And this "no changes at hunks level" was the reason for test-split.t breakage as now it didn't prompt for those files which are passed on cli. To fix this I have included some content in those files to make sure that tests still demonstrate the same behaviour as they were doing before breakage. Also, I replaced some "n" with "s" as it make more sense to skip all the changes to that file in one go instead of hitting "n" multiple times (if there were multiple hunks)

test: add file cancelation scenario for phase-divergence This improve the test coverage for corner cases.

changelog: mention issue6089 fix

pick: update working dir branch (issue6089) Previously the working copy was left in an "inconsistent" state.

tests: rename test-grab to test-pick This match the new command name.

evolve: make sure div resolution don't replace the initial author (issue6113) Before this patch, divergence resolution logic taking the current user who is running the resolution command as the author of commit that will be created after merging the two divergent csets. This patch make sure that we preserve the initial author. Changes in test file reflect the fixed behaviour.

evolve: add test which demonstrate issue6113 This patch introducing a new test file which contains the test for issue6113 which is `test-evolve-content-divergent-distributed.t`. This test file is supposed to contain tests for distributed workflows. Next patch will fix the bug.

test: consolidate the content-divergent test cases This commit move most of the content divergent related test in dedicated and thematic test files.

changelog: mention the fix to issue6057

extensions: avoid enabling evolve for unrelated repositories (issue6057) The support for the `experimental.evolve` config have been there forever. So we can stop using the global variable. This help avoiding evolve to enable itself of repository that did not explicitly activated it. For example, this is useful for hgwebdir. Before this change, evolution feature had to be explicitly disabled or enabled in every single repository.

stack: improve set combination logic

stack: fix phasecache._phasesets check logic When _phasesets is not None, it's a list, and it contains set()s of revisions in a specific phase, starting from public, draft, secret and so on. But since repos are supposed to have the majority of revisions in public phase, the first element of this list is not a (potentially huge) set, but None. Previously this code tried to check if there's any element that is None, and was always finding None at index 0, so the short path was executed every time and the rest of the function was never used.

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.

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

evolve: remove unused StringIO import

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

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

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.

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

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.

branching: merge with stable

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: add test for the case where public divergence on difference parents This test make sure that public divergence resolution also handle the case when divergentes changeset does not share the same parent at one end because one end simply rebase. The other side has actual an actual diff change. For now this would work only for the case when we need to relocate the mutable one. Other case is still left to work on.

evolve: update the public divergence resolution logic to cover --continue case To continue the interrupted evolve in case of public divergence: we will have to store the node of that public cset which was in content divergence with the other cset, so that we can perform the phase divergence resolution between that public cset and a newnode which is the result of content-divergence resolution. Added tests reflect the behaviour this patch adds.

evolve: add logic to resolve content-divergence with a public cset Public content-divergence is the divergence where a cset is content-divergent with a public cset. To solve public divergence: 1) perform content-divergent resolution 2) resultant node is phase divergent 3) perform phase divergence resolution It is the intial logic to solve public divergence. Next patches will be the covering the cases of: 1) relocation: when we need to relocate to node 2) continue: to add this resolution in case of --continue 3) the case when content-divergence resolution gives a result similar to public cset. Added test-evolve-public-content-divergent.t reflect the added behaviour.

evolve: introduce function to create a obsmarker relation even for public cset To create obsmarkers we use obsolete.createmarkers() function, but because of security reasons this function refuses to create obsmarkers for public cset. And we need to create obsmarkers for a public cset while solving public content divergence. So introducing this function which create a obsmarker relation even for immutable cset. Currently this function create obsmarker for a single relation, in contrast of obsolete.createmarkers() which create markers for multiple relations. Upcoming pathces will be using this function.

topic: make ranges work in revset relations like 'foo#stack[1:2]'

topic: simplify #stack index check/access Also using stack.revs instead of list(stack). It's equivalent and stack.revs is @propertycache'd.

topic: make ranges work in revset relations like 'foo#topic[1:2]' Since #topic is very similar to #generations, we reuse the function directly. Few tests because #generations is already tested in core.

Let's add a comment to maybe help the person not make the same mistake.

evolve: make "startnode" consistently be a node, not a context This fixes a bug where we didn't print "working directory is not at ..." after `hg evolve --continue` because we were comparing a node and a context.

evolve: use context managers for locks and transaction

prune: use scmutil.cleanupnodes()

uncommit: use scmtutil.cleanupnodes()

amend: use scmutil.cleanupnodes() with --patch

obsdiscovery: use consistent filtering during discovery If we computed revision using an unfiltered repository, we should run the discovery unfiltered too.

evolve: make sure we don't stop after evolution of obsparent (issue5881) Before this patch, we were not handling the case when revset given by user also contain wdir parent which is obsolete. We were explicitly checking if wdir parent is obsolete, then update to its successor and return; without checking if we still have some revisions to be evolved. This patch make sure that after it update to the successor of obsolete parent it doesn't stop and continue to evolve other remaining revisions. Changes in tests/test-evolve-issue5881.t reflect the fixed behaviour.

evolve: extract "update" code into its own function This patch moves the code to a function which handles the case when wdir parent is obsolete and evolve will just update to its successor. And extraction of this to a function will also help us to fix the issue5881.

And the reason behind crash is that `lastsolved` is not being updated and contain a wrong value which is now hidden. Next patch will fix this problem.

next: populate stacktemplate to the missed _nextevolve function

evolve: adapt for deprecated ui.progress() This makes a wrapper that has an interface like ui.progress() even though that's the old interface that will eventually go away. That's because it's a lot easier to convert from the ui.progress() to the ui.makeprogress() interface than the other way around. Once we no longer support hg<4.7, we can migrate our callers to ui.makeprogress() and drop the wrapper.

fold: sort concatenated commit messages in topological order It seems better to have the proposed commit message look the same whether the user ran `hg fold --exact -r . -r .^` or `hg fold --exact -r .^ -r .`.

topic: make revsets like 'foo#topic[0]' work Essentially, 'topic' relation subscript function is the same as 'generations', but is limited to revisions marked with one particular topic.

changelog: add an entry about the revset stack indexing

test: adapt output to minor behavior change CORE-TEST-OUTPUT-UPDATE: bad05a6afdc8

tests: remove unused variable and needless subshell in testlib/pythonpath.sh

branching: merge with stable

tests: conditionalize some output for Windows A couple of these were already present, but out of place.

test-pyflakes: use '/' when printing the files to check If paths are printed with '\', `xargs` sees the parts allsmooshedtogether, and pyflakes errors out.

tests: fix PYTHONPATH manipulation on Windows Without the semicolon separator and quotes, the variables ends up like this: c:\Users\Matt\projects\hg-evolve:c:\Users\Matt\projects\hg-evolve: c:\Users\Matt\projects\hg;c:\Users\Matt\projects\hg-evolve\tests; c:\Users\Matt\projects\hg\tests That in turn makes the local evolve code unreachable, and the system installed code is tested instead. I'm testing against `uname` instead of a trivial python script printing os.name because maybe one day tests will run on WSL.

exthelper: update documentation with some examples for using registrar aliases

exthelper: simplify the ability to register filesets Same mechanism as revsets earlier in this series.

exthelper: simplify the ability to register templates Same mechanism as revsets earlier in this series.

exthelper: simplify the ability to register revsets I think this is what Yuya and Boris agreed on.[1] This happens *after* the extsetup phase now (and after the _aftercallback notifications). But this is trivial, mergeable between exthelper instances, and doesn't need to have the extension name supplied when registering. [1] https://www.mercurial-scm.org/pipermail/mercurial-devel/2018-December/125888.html

exthelper: support the option argument when registering a command Largefiles uses this 5th argument with push and pull, so this will be tested in the next commit. I assume the reason for unrolling and reforming the tuple in each finalxxxsetup() is to validate that something proper was passed in when registering. But it's better to explode when decorating than during the delayed actual registration.

exthelper: simplify configitem registration

exthelper: avoid a [] default arg to wrapcommand()

configitems: move the default values to the registrar decorator The exthelper refactoring of configitems stopped registering dynamicdefault for everything, which in turn causes a lot of warnings about mismatched defaults. There are a few stragglers- I didn't fix topic-mode because I wasn't sure what the default should be, and the alias for odiff was explicitly given a default for compatibility.

topic: make revsets like foo#stack[-1] work too We remove base commit when n < 0 because it's confusing to see base (which technically isn't a commit inside the stack) at both 0 and -n.

topic: make revsets like 'foo#stack[0]' work 'stack' relation subscript function is another way to refer to s0, s1, etc. But instead of aborting in many cases it will simply return an empty set.

exthelper: remove '_' in final_xxx() function names to conform to hg style

evolve: detect unresolved conflict during evolve --continue (issue5966) Evolve --continue was ignoring unresolved conflict, proceeding with its operation without any check. This is now fixed. This test case was built and formalized by Matt Harbison and Anton Shestakov.

tests: filter out uninteresting log events Core has new ui.log() calls added (for tracking extension loading and performance, for example), but in test-discovery-obshashrange.t it produces a bunch of lines that are unrelated to the test. So we filter them out to not touch test output. This is inspired by 1de3364320af in core.

split: add a --interactive flag While the interactive mode is useful for end-users, there are some cases where they don't need the interactivity overhead. Moreover, this allow the split command to be used in automated scripts.

split: take file patterns to limit selection on matching file patterns When splitting a big changeset, the user often wants to extract specific files from the changeset while leaving the others files intact. The split command can now be called with multiple file patterns. Only files that match one of the patterns will be shown in the interactive selection. The user will be able to create one or more commits with those files. When the user finishes splitting the matching files, a last commit will be made with the remaining of the files.

split: only accept explicit revision through the `-r` option We are about to introduce new non-optionnal arguments to defines files patterns. To avoid confusion and to be closer to the standard options, only accepts revisions with the `-r` option.
