py3: implement __bool__ in addition to __nonzero__

py3: replace iter.next() by next(iter)

py3: replace xrange() by range()

py3: read sqlite3 data as bytes The py2 and py3 docs ([1] and [2]) disagree how to get bytes output, but it seems obvious that this should be "bytes" to be compatible with both. [1] https://docs.python.org/2/library/sqlite3.html#sqlite3.Connection.text_factory [2] https://docs.python.org/3/library/sqlite3.html#sqlite3.Connection.text_factory

py3: sqlite3.connect() expects str arguments

cleanup: remove check only needed for hg versions before 4.4 ui.edit() has had the "action" argument since 6e6452bc441d (editor: use an unambiguous path suffix for editor files, 2017-08-30), which was first released in hg version 4.4. Since we support only versions higher than 4.5, we can drop this check.

split: remove an unnecessary (and confusingly typed) fallback revision `opts.get('rev') or '.'` is either a list of strings or just a string. It happened to work because `'.'[0] == '.'` on Python 2, but it won't work on Python 3 (for byte strings). The fallback value wasn't even needed (it was also set just after), so let's just remove it.

evolve: rename variable "children" to "child" where it's clearly singular

evolve: remove some unused variables

py3: back out 23323092f0a7 D6623 has now been accepted in Mercurial (commit 83666f011679), so evolve commit 23323092f0a7 (py3: convert _origdoc to sysstr to match __doc__, 2019-07-09) is not longer needed.

branching: merge with stable

touch: fix the inconsistent behavior of divergence catching logic (issue6107) When touching a node, the way we check if it can lead to divergence is we look at the successors sets of the rev being touched. And if there is successor revs exists (excluding the case when that successor set is (A,) for rev A) that means there will be divergence and we warn the user. This works fine but there is still a case (which is not covered by looking at successor sets) which can lead to divergence. That case is: when there is already a revision exists which is divergent to the revision being touched. And performing the touch would revive that "dead" divergence. (Dead because one of the revision is obsolete which is the one we are touching) And to see if there is any rev which is divergent to a particular rev we already have a function which we can use here i.e. `evolvecmd.divergentsets(repo, ctx_being_touched)` Changes in test file demonstrate the fixed behaviour.

touch: add test which shows touch can fail to warn about divergence

touch: clarify some inline documentation

tests: update output for new branch cache messsages from Mercurial This makes tests pass again after Mercurial commit c7d236b55a3e (py3: fix formatting of branchmap log messages with repo.filtername=None, 2019-07-14). CORE-TEST-OUTPUT-UPDATE: c7d236b55a3e

metaedit: allow operations on merge commits with some conditions As with fold (see the previous patch), it's allowed to metaedit a merge commit or a set of commits including merge commits (with --fold) as long as there are less than 2 parents of the set not included in the said set.

fold: allow operations on merge commits with some conditions It's possible to fold revision chains that include a single merge commit: just fold everything into the merge commit while saving its other parent (so it continues being a merge commit). It's also possible to fold revisions that include multiple merge commits, on the condition that they merge with not more than 2 external changesets (i.e. a changesets that aren't going to be folded).

rewind: make sure merge commits include files from p1 and p2 Otherwise rewinding a merge commit makes it lose all changes. This fix populates `updates` argument of rewriteutil.rewrite() with parent changesets. That argument is normally used for folding multiple changesets, but in this case it's simply used to include files from p1 and p2. Usually, rewrite() works fine using ctx.files(), but that function can return an empty list when ctx is a merge commit.

rewriteutil: allow rewriting merge commits (issue4561) This patch simply allows rewriteutil.rewrite() to work with commits with multiple parents (i.e. merges). That function is used in such commands as fold, metaedit, touch, rewind. The issue 4561 is marked as easy, the limitation is called unnecessary, no tests fail after this change. What can go wrong.

tests: show what happens when trying to hg touch a merge commit

evolve: further clarify that update is performed only when requested Text further modified by Pierre-Yves David and Anton Shestakov.

touch: let's not use util.acceptintervention() as it's not required

branching: merge with stable

evolve: use right value for branch name when finding branch heads subbranch already formatted as "branchname:topicname", again appending it with ":topicname" doesn't not make sense. It's a little bit surprising that no tests fails though.

evolve: fix confusion in branch heads checking logic when topic in play To provide some context, when topics are in play the branchmap cache we store contains the branch info of a rev as "branch:topic" format IIUC. Assuming that is right, now in present code we don't actually cover this part that "when looking for branch heads where we also have active topic we should look for branch='branch_name:topic' instead". And we get wrong branch heads as a result. This patch make sure that we pass right candidate to find branch heads using branchmap.branchheads() by overriding the localrepo.branchheads() Changes in test file reflect the fixed behavior.

topic: add tests to demonstrate topic confuses the branchhead checking logic While topics are in play, we store the branchheads (which has a topic) in "branchname:topicname" format. After digging into it I found that even in the case when we should have branch heads for "bname:tname" we get heads for "bname". The tests output reflect the confusion in branch head checking logic. Next patch will be fixing the problem.

evolve: fix the inconsistent behaviour of prune (issue6137) Let's not update to any revision when working directory parent is not related to the revision being pruned. Changes in test file demonstrate the fixed behaviour.

prune: add tests to demonstrate issue6137 Here we can see that prune updates off to the parent revision even when the pruned revision wasn't related with the working directory parent. A follow-up patch will fix this.

compat: fix `setupevolveunfinished` for upstream

prune: update to the successor of wdir also with --pair/--biject (issue6142) When prune is used with --pair flag, we can also update to the successor of working directory parent. No need to check len(sucs) or len(precs) here because there's a check for that earlier in the code (it's a requirement of biject). The tests are now demonstrate the correct behavior: when rev 14 was pruned with 12 as its successor, the bookmark that was on 14 was moved to 12. That bookmark was also activated (even before this patch).

tests: demonstrate prune --pair not moving bookmark correctly After `mkcommit n2` line the bookmark is on the correct changeset, but when we prune --pair the two newly created changesets (revs 13 and 14), the bookmark gets moved to their ancestor (rev 0). Instead, it should've moved to the last of their successors (rev 12).

oops: backed out changeset 7ac40b4ea24c Anton requested some changes on it.

compat: fix `setupevolveunfinished` for upstream

evolve: fix the code flow pattern of solving obswdir par and troubled revs Now we will go to _handlenotrouble() (which prints messages about no revs to solve) only when there is no troubled revs and working dir parent is not obsolete. This change also saves us from an issue which was about looking into the revset (smartset contains troubled revs to solve) when a rev from the revset gets hidden. This happens in the case when our wdir parent is obsolete. After resolving obswdir parent we were looking into the revset to check if there is any troubled revs to solve but we should have performed this check before performing the obswdir resolution. Changes in test file reflect this fixed behaviour.

evolve: refactor for consistent behavior of evolve when wdp is obsolete This patch make sure that when working directory parent is obsolete `hg evolve` and `hg evolve --all` don't behave differently.

evolve: backout 3027005c42c3 to reintroduce a bug for right fix This patch backout 3027005c42c3 as it was accepted by mistake while it was being "in-discussion" state.

pick: register pickstate as an unfinished state This way pickstate file will indicate that unfinished pick command needs to be dealt with (--continue or --abort) before modifying the repo. Otherwise it would be e.g. possible to commit during an interrupted pick and that's not expected.

pick: rename variable for unfinishedstates

pick: actually delete pickstate if --abort is given Makes pick to be, uh, actually aborted.

evolve: orphans that evolve into nothing don't need successors (issue5967) When continuing to solve an orphan that created no changes (i.e. clean wdir), _completeorphan() used to create an obsmarker that said that the result of that orphan evolution is the currently checked out changeset. That's not a correct obsmarker, because all of the orphan's changes were dropped and so it had no effect on the currently checked out changeset. This is an issue that has only existed when --continu'ing evolve, that's why the fix touches _completeorphan(), but not _solveunstable(). This fix is adapted from a similar "if node is None" block in _finalizerelocate().

tests: demonstrate obsmarker creation after discarding conflicting changes Continued evolve creates an incorrect obsmarker that says 2 is a successor of 1. It's incorrect because 1 was dropped as it created no changes to commit (after conflict resolution that discarded its changes). If evolve does the same thing in one go (e.g. just by using --tool :local and without subsequent need to continue) the obsmarker is correct.

pick: remove transaction on the whole command (issue6037) At its core, pick is a pretty straightforward and well-behaving command, it uses functions already in core hg, it checks that wdir is clean and that changeset to pick is not public, it checks if there happen to be merge conflicts and can be --continue'd later, etc. It is very similar to graft in core (it also uses mergemod.graft function), but it obsoletes the original changeset. However, graft does not experience this incorrect behavior from issue 6037. What happens in the test case for this issue when we pick a revision that touches both "a" and "b": mergemod.graft() takes the original changeset and tries to apply it to the wdir, which results in "b" being marked as newly added and ready to be committed, "a" updated with the new content and being marked as modified, but "a" also has conflicts. Pick correctly notices this and saves its state before asking for user intervention. So far so good. However, when the command raises InterventionRequired to print a user-facing message and exit while being wrapped in repo.transaction() context manager, the latter partially undoes what mergemod.graft() did: it unmarks "b" as added. And when user continues pick, "b" is therefore not tracked and is not included in the resulting commit. The transaction is not useful here, because it doesn't touch wdir (it's still dirty), it doesn't remove pickstate (and other commands will refuse to work until pick --abort or --continue), it just makes "b" untracked. The solution is to use repo.transaction() only to wrap code that writes data to hg store in the final stages of the command after all checks have passed and is not expected to fail on trivial cases like merge conflicts. For example, committing the picked changeset. But since pick uses repo.commit() for that, and because that function already uses a transaction, wrapping it in another transaction doesn't make sense.

tests: demonstrate hg pick forgetting files after conflicts This test currently passes to show that pick is behaving incorrectly.

packaging: follow hg's supported python version (>= 2.7) "Mercurial 4.3 and newer require Python 2.7." (From https://www.mercurial-scm.org/wiki/SupportedPythonVersions) Also add X- prefix, because that's the correct form, apparently. This line can also be removed in future, since "When Debian supported multiple Python versions, X-Python-Version was used, but it is obsolete now as no supported Debian release supports anything other than python2.7." (From https://wiki.debian.org/Python/LibraryStyleGuide) That page also mentions "X-Python3-Version".

packaging: require hg 4.5 also for usage, not just for building

packaging: require mercurial >= 4.5 Otherwise building the doc package fails with: (third party extension evolve requires version 4.5 or newer of Mercurial; disabling) Exception occurred: File "/usr/lib/python2.7/dist-packages/mercurial/help.py", line 624, in help_ raise error.Abort(msg, hint=hint) Abort: no such help topic: evolve

evolve: clarify why returning by adding inline doc

evolve: move a code block to have right value in has_some_val Because of this we were having wrong value of has_some_val and had some buggy behavior which is being fixed by this patch. Fixed behavior is reflected by the changes in test file.

topic: add tests which demonstrate topicset failure of FilteredRepoLookupError When topics are used, it fails to find hidden revs mentioned in a revset as we are not using unfiltered view of repo. Next patch will fix it.

pick: reduce configoverride() scope Merge tool is only needed for merge.graft() (it's what graft in core hg does), so let's make the scope of the ui.configoverride() narrower.

evolve: correct action verb in a message

evolve: internationalize a message This exact message was already wrapped in _() in the same file, just not here.

evolvecmd: the proper way to deal with conflicts is to resolve them And it's worth making the suggestion an actual hint.

Added tag 9.0.0 for changeset 756db65030c6

packaging: prepare release 9.0.0

doc: clarify the status of configuration of the obshashrange protocol

changelog: add various missing bits

templatekw: keep compatibility with Mercurial 4.5 This is simple enough to do.

test: adjust output to stable branch We are about to make a release.

branching: merge with stable

templates: don't alias keywords directly Putting the same function twice in the registry results in duplicate doc strings and therefore confusing "hg help template" output.

stack: remove 'topic.' prefix from colors/labels Stack is related to topics, sure, but it is also good enough to be recognized on its own.

stack: handle hash sizes when --debug flag is provided Since showstack() now uses fm.hexfunc() for node hashes, which depends on ui.debugflag, we should handle situations when hashes are full-sized as well.

stack: always provide (full) node hash to non-default --template

stack: remove unnecessary prefix from stack output with non-default --template "index" template keyword already exists (the current iteration of the loop), so "stack_index" it is. It follows the same convention as other template keywords, such as "files_added", "line_number", etc.

stack: provide context to formatter with non-default --template This allows using template keywords that we don't explicitly provide to the formatter, e.g. rev, branch and topic.

stack: leverage labelsgen() to produce all needed labels for fm.write()

stack: check if stack is empty more pythonically

stack: implement __bool__ and __nonzero__

stack: get stack data directly from stack and remove stackdata() stackdata function began its life in 137f8b04901e as a proto-stack: it computed stack revs on its own and only had one property to return, "changesetcount". Later it started to prepare and return more properties, but since b933a8068c17 it was computing revs using a getstack function. And then finally in 17749d9d3968 it started to rely on stack class entirely. It was a good function, but now, when all the logic it provided was factored into stack class, I'd say it's finally time for it to be put to rest.

stack: use stack._revs instead of stack.revs[1:] in external children revset The revset in question excludes all revs that are part of the stack. Using stack.revs[1:] works (rev #0 is stack base, which is not a part of the stack), but using stack._revs is technically more correct, because this variable is specifically designed to hold only revisions that are part of the stack.

test: update output to match the parent changesets This amend was forgotten.

topic: add a simple option to reject publishing The option is pretty basic but it can be used as base to build larger feature. The main target for going in this direction is to be able to distinct between user that are "simple contributors" pushing topic for review and the "maintainers" or "automation" that can publish changesets.

compat: adjust `wrapadd` for upstream Mercurial core updated the API in f385ba70e4af.

debian: override default value for SPHINXBUILD in docs/makefile This is the recommended Debian approach. As suggested by Debian Developer Stephen Kitt, use the approach recommended by Debian for building Sphinx documentation. See https://wiki.debian.org/Python/LibraryStyleGuide#Sphinx_documentation Also belated credit to Zash on the #mercurial channel on the Freenode IRC network, who suggested the Make variable approach in the first place.

obshashtree: move obshashtree in its own module The code no longer serve a core purpose. We just keep it because the command might be useful. We move it in a dedicated module so that it does not get in the way of other work.

obsdiscovery: drop `obshash` discovery protocol (issue6136) The protocol has been superseeded by stablerange for a long time. It is untested and more and more buggy. Since this is deprecated experimental code in an experimental code, we drop it. We keep the underlying computation and debug command around for now. They might still be useful to looks at repositories

cmdrewrite: use context manager for some locks and transactions These were the trivial cases where I didn't even need to extend the scope of a transaction or change indentation to fix it.

evolve: mention that --all is default, in list of options

touch: use util.acceptintervention() for closing the transaction It will close the transaction on InterventionRequired.

touch: use context manager for locks

touch: extract the logic of touching rev's to its own function This refactoring will also help us in using the context manager for locks in next patches and also help reducing the nested depth.

changelog: mention user merging in the changelog

evolve: consider using three way merge to get the user for div resolution This patch adds the logic to merge the users from two divergent csets considering the base (i.e three way merge). The case when all the three are different, we concatenate the two authors of divergent csets.

evolve: add tests for the case when div csets has different users

branching: merge with stable

evolve: move status msg to verbose mode in content-divergence resolution As suggested by Pierre-Yves, lets move these too verbose message for the user to verbose mode to decrease some noise.

debian: Override default value for SPHINXBUILD in docs/makefile Sphinx now defaults to Python 3 in Debian Buster, so we need to explicitly select the Python 2 version of sphinx-build for building docs.

docs: add SPHINXBUILD make variable This defaults to sphinx-build. The current use case is for the Evolve Debian package build.

topic: add test to increase code coverage in case of multiple topics This patch adds a test which cover the part that when we have one topic on top of other topic, this make sure that when evolving it's boundary are the current active topic (i.e hg stack)

changelog: --no-update is the default, recommend --update instead

topic: drop support for accessing csets in branch stack using bxx (issue6119) When topic extension is enabled and we have some cset whose hash is `b1234`, topic extension thinks that we are accessing 1234 cset in current branch stack. However that's not the case generally. Also I am not sure many people use this bxxx thing. Since we have a generic sxxx way to access csets, let's drop support for accessing csets using bxx which leads to bad behavior. Looking at the tests, we don't show bxxx in hg stack output anymore. I update the test to use sxxx instead of bxxxx.

legacy: drop the check for `obsolete._enabled` This looks like an ancient version check, and presumably `minimumhgversion` will do the same thing.

docs: drop references to the old temporary commit that was created with amend The sharing.rst page also mentions amend, but the diagrams aren't showing, so I'm not sure if they're in some other repo and needing to be updated.

templatekw: add `instabilities` alias for `troubles` Per https://www.mercurial-scm.org/wiki/CEDVocabulary

revset: switch internal uses and tests to `predecessors` from legacy name

revset: add `predecessor` aliases for `precursors` and `allprecursors` Per https://www.mercurial-scm.org/wiki/CEDVocabulary

revset: add `unstable` alias for `troubled` Per https://www.mercurial-scm.org/wiki/CEDVocabulary. The old name is still available (but undocumented) for compatibility. `Orphan` was renamed from `unstable` in core in 4.4, so this seems safe to do now.

docs: change `bumped` references to `phase-divergent` Per https://www.mercurial-scm.org/wiki/CEDVocabulary

docs: change `troubles` references to `instability` Per https://www.mercurial-scm.org/wiki/CEDVocabulary. There are a couple instances of 'troublesome' which probably need a word, as deriviatives of 'instability' didn't really fit. At least some of these are in the unlinked obs-terms.rst page.

docs: change `precursors` references to `predecessors` Per https://www.mercurial-scm.org/wiki/CEDVocabulary

docs: import figure diagrams with inkscape 0.92 No changes to the content here. This simply accepts the default option ("This file contains digital artwork for screen display") on the prompt when first opened, which is trying to upgrade from 90DPI to 96DPI.

messages: standardize on "working copy is now at" including "is" It seemed that we mostly used "is", but `hg next` and `hg prune` could print it without the "is".

evolve: move more of the progress-related variables together

evolve: delete dead calculation of number of troubled revisions The "count" variable is recalculated in the regular (no --continue) code path and it isn't used anywhere else (it used to be set to 1 in the --continue code path, but that now has its own progress counting).

evolve: drop nested locks and transactions All callers of _solveone() now take the locks and start the transactions, so there's no need to do that anymore.

next: start transaction before calling _solveone() All other callers do this, and I'm about to make _solveone() not create a transaction.

evolve: use single transaction also when continuing

evolve: run in a single transaction This speeds up `hg evolve --all` of a stack of 24 commits in the hg repo from 11.5s to 3.7s (3x). As can be seen in the tests, it also avoid some warnings about transiently unstable commits.

evolve: extract function for solving one revision, including merges Will make the next patch simpler.

evolve: mention that --all is the default behavior now

evolve: mention that not all successful operations currently update wdir

evolve: add progress support for --continue The progress starts where it left off when the previous command ran into merge conflicts.

evolve: reduce scope of progress-related variables

evolve: move progress-clearing out of _cleanup() The progress is only used with --all or --rev, so there's no need to clean it in any other case. It's therefore easier to clean it specifically in that case.

evolve: stop passing no-op "progresscb" into continueevolve() The "progresscb" doesn't do anything in the --continue case, so there's no need to pass it into continueevolve(). This lets us remove the --no-all that was added to the test as a workaround.

evolve: _solveunstable() update progress only once There's no need to draw it, then possibly write text over it (with --verbose), and then draw it again.

evolve: don't update progress just before clearing it _cleanup() will clear the progress, so there's little reason to update it just before (except for progress.debug=yes).

evolve: clean up progress bar also when using -r It looks like 1fe3da0b4601 (evolve: add --rev option to the evolve command, 2015-05-05) forgot to update the "showprogress" variable.

tests: add some basic testing of progress

evolve: increment progress *after* a whole merge commit is done The "re-stabilize" step was using the progress that was supposed to be for the next revision.

evolve: use util.acceptintervention() for closing transactions util.acceptintervention() will close the transaction on InterventionRequired.

evolve: use context manager for transactions

evolve: use consistent message and just re-raise InterventionRequired

evolve: use standard InterventionRequired instead of MergeFailure

evolve: don't use exception for local flow control The LocalMergeFailure class was added in 3f91654713dd (obsolete Move merge failure handling into stabilize code, 2012-08-20). I think the "if compat.hasconflict(r)" check was added later. Now that we have that check, we should use that for flow control instead. Note that this means that any unexpected exception from _relocatecommit() will now just raise (and roll back the transaction). I think that's an improvement.

evolve: reduce indentation with an early return statement

evolve: remove a useless return statement at end of function

test: move a test to an appropriate test file This patch introduce a new test file test-evolve-orphan-corner-cases.t for tests which covers corner cases.

test: improve the title of a test

test: remove duplicated test We have the test in test-evolve-orphan-split.t which is covering the same case this test does. Also this test states that evolve shows some error in split case, but now this is not the case we update to the top of splitted csets.

evolve: warn user for the metadata being lost in public divergence resolution This patch print warnings if some "extras" of a divergent changeset that is possibly important metadata which is being lost during the resolution of public divergence.

evolve: show a status message when merging leads to public cset I think it would be fine to tell the user that merging the two divergent csets while resolving public divergence resulted into the public cset itself. If you think we don't need to tell the user, then we can include this in debug-mode for debugging purposes at least.

test: use a shorter test name This is still long but easier to read.

stack: rename troubledcount to unstablecount

evolve: use --all by default (BC) allopt defaults to None to avoid touching _checkevolveopts(). If it were True by default, that function would always act like the flag was provided by user, and so using --abort, --stop, --continue or --rev on their own would never work (hg evolve will complain that you cannot specify both --rev and --all). A notable change in tests is "no troubled changesets" line that gets printed when using `hg evolve` to update to the evolved successor of working directory parent, but there were no actual instabilities.

tests: add --rev to hg evolve to reduce test changes for the next patch

tests: add --no-all to hg evolve to reduce test changes

evolve: don't update after instability resolution by default (BC)

tests: add --update to hg evolve to reduce test changes for the next patch

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. [This re-install a changeset backed out for compatibility reason]

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.
