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".

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().

changelog: add relevant entries

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.

evolve: add description of function solveobswdp

evolve: document the "if not shouldupdate" block I missed the "not" in "if not shouldupdate: ... hg.updaterepo()" and it took a long time for me to realize it's about updating *back* to the original commit (or to its successor). 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

pick: use scmutil.cleanupnodes() A side-effect is that `pick` should now also move bookmarks.

fold: use scmutil.cleanupnodes() scmutil.cleanupnodes() has existed since 4.3 and had the metadata argument since 4.4, so we can now safely depend on it.

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.

evolve: add test case for issue 5881

evolve: add test which shows fixed behaviour of `hg evolve` (issue5686)

evolve: cover the orphanmerge part missed by lastsolved Let's cover the orphanmerge part also as it was missed at the time when we introduced "lastsolved". Chagnes in test-evolve.t reflect the fixed behaviour.

evolve: add test which shows orphan-merge resolution can result to crash It happens when there are still some revisions to evolve after evoluiton of a orphan-merge. 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.

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.

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.

issue-6028: resolves 6028 - return (False, ".") instead of (False, '') Since 4.8, repo[] no longer takes an empty string, so we update to a valid with similar semantic. This value is strange and we should probably use an actual node ID here, however, this is an independent issue.
