packaging: fix debian changelog

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.

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.

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.

branching: merge with stable

tests: add sparserevlog cap since hg now has sparse revlogs by default CORE-TEST-OUTPUT-UPDATE: 3764330f76a6

split: rework the prompt to be more standard We dropped the initial capital and moved to a positive question.

split: add a option to discard remaining change during split This is useful to drop unwanted remaining change spotted during the split.

split: add a way to abort a split from the prompt This prompt is asking the user about the next step. Offering to abort there make sense.

split: add a help entry to the final prompt We are about to add more option in this prompt. Adding a way to document then seems like a good first step.

topic: make revset argument messages be similar to such messages in core

tests: don't forget to add hg serve pid to DAEMON_PIDS in test-wireproto.t Otherwise it leaves a process running after each run-tests.py launch.

test: adapt to change output change on default We now have a `wcache` directory in `.hg`.

safeguard: don't reimplement auto-publish if it's in core (will be in 4.9)

safeguard: the new default for auto-publish is 'publish'

stack: add a --children flag to stack If a commit in the stack has been merged outside the current topic, show a trailing status of (external-children)

extensions: avoid shadowing imported module names with exthelper methods The previous code worked, but confused pyscripter.

extensions: add fileset support to exthelper This will be tested by using it in lfs.

extensions: add uipopulate() support to exthelper

exthelper: clarify copyright and licence for the module The exthelper is quite useful and Matt Harbison is looking into having it upstreamed. We clarify the legal situation first.

packaging: merge with version 8.3.2

changelog: add information about the topic message improvements

branching: merge with stable

evolve: update the abort to a ProgrammingError This error should be a ProgrammingError and as Pierre-Yves David said ProgrammingError type did not existed when this code was written, so lets update this now.

topics: improve the message around topic changing The new message says 'cleared' when topic name is cleared, if we change to a new topic name, it mentions the new topic name too.

tests: fix for POSIX compliance * Mac ls will exit with a different message and exit code [1], replace with grep (which is what mercurial tests do) * POSIX echo has no -n switch, use printf instead

style: remove unused variables Both `as e` references are not used and can go.

evolve: fix a documentation typo

compat: drop 4.3 related obsfate code All the necessary piece are supported starting 4.4.

compat: drop code dealing with incompatibility for --publish with 4.3 We dropped 4.3 support.

compat: clarify when some conditional are used The middle condition was an intermediate state that never existed into a release. We can safely drop it.

compat: drop 4.3 "new troubles" report code This is supported natively for Mercurial 4.4 and above.

compat: drop 4.3 wrapping of createmarker for effect flag support This is supported natively in 4.4 and above.

compat: drop 4.3 monkey patch of `copies.mergecopies`

compat: drop 4.3 compatiblity code for `obsutil.allprecursors` function

compat: drop 4.3 compatiblity code for `ui.edit` method

compat: drop 4.3 compatiblity code for 'successors' revset

compat: drop 4.3 compatiblity code for 'precursors' revset

compat: drop Mercurial 4.3 support for exthelper The last release email noted plans to drop 4.3 and 4.4 support in the next feature release. I'd like to move this code into core, and dropping this should allow the class to be copied in unmodified.

compat: update metadata about minimum ag version

next: solve the issue of `next` get confused by split This patch solve a problem of next command which get confused by split. Let me describe how it was getting confused: Initial state of repo: A---B---C After splitting B to (B1,B2): @ A---B1---B2 \ ---B---C X * (note: C is orphan; checkedout to B1) Lets make an amend on B1: @ B1' / A---B1---B2 \ X * \ ---B---C X * Now, if run `hg next` (--evolve is True by default now): $ it would give you choice to choose from B2 and C thinking that C could also be a possbile children for B1, instead of stablizing B2 on B1. I fixed this problem by filtering those aspiring children which can be stablized on one of the aspiring children itself. Changes made in test-prev-next.t shows the changed expected behaviour.

next: add test which shows that `next` get confused by split

cleanup: avoid a Yoda condition

evolve: modify and move the comment to appropriate position

next: update the command description Now, if necessary next command evolve the next child revision by defualt. You don't need to pass the --evolve flag.

next: make next command --evolve by default Before this patch, if we need to evolve to update to the next child, we were suggesting the user to use --evolve flag. This patch make some changes to evolve by default in that conditions. After making next command to evolve by default we have to consider the following points: 1) If we don't need to evolve while updating to the next child: a) And if wdir is dirty, we suggest to use --merge flag b) if wdir is clean, we simply update to next child (if ambiguous, prompt the user to select one) 2) If we need to evolve: a) when wdir is dirty, we suggest the user to use `hg shelve` first, to make wdir clean. As we don't support --merge while evovling. b) when wdir is clean, we evolve the next cset. Changes made in test-prev-next.t reflect the changed behaviour.

safeguard: allow push to succeed (and without warning) with --publish

topic: only add --publish flag to push if it's not already there

safeguard: check auto-publish value before sending listkeys command Always sending listkeys command is just wasteful, let's first make sure users even care about auto-publish behavior.

style: silence another flak8 warning Default should be green now.

oops: backed out changeset df22f010cf24 pushed by error The changeset still fails some test

next: make next command --evolve by default Before this patch, if we need to evolve to update to the next child, we were suggesting the user to use --evolve flag. This patch make some changes to evolve by default in that conditions. After making next command to evolve by default we have to consider the following points: 1) If we don't need to evolve while updating to the next child: a) And if wdir is dirty, we suggest to use --merge flag b) if wdir is clean, we simply update to next child (if ambiguous, prompt the user to select one) 2) If we need to evolve: a) when wdir is dirty, we suggest the user to use `hg shelve` first, to make wdir clean. As we don't support --merge while evovling. b) when wdir is clean, we evolve the next cset. Changes made in test-prev-next.t reflect the changed behaviour.

next: improve the message for dirty working copy with --evolve This will be important soon when --evolve will be the default.

next: use the `hint` argument of bail if changed The argument is availabel since Mercurial 4.1. So let's use it.

prev: use the `hint` argument of bail if changed The argument is availabel since Mercurial 4.1. So let's use it.

next: explicitly specify --no-evolve in the tests The default value for this flag is about to switch.

branching: merge with stable

style: fix various flake8 warning

next: set if we need to evolve or not; also move logic to appropriate pos set the value `needevolve` and also move the logic to find aspiringchildren to appropriate position i.e before we suggest user to use other flags like --merge.

next: move some code to prepare for `next --evolve` by default Moved some values before the block where we suggest the user to use --merge flag. As we would need these values to find if we need to evolve or not before we can suggest user to use `--merge` flag. We will suggest user to use `--merge` flag only when we don't need to evolve. Because currently we don't support both --evolve(going to be True by default) and --merge at the same time.

branching: merge with stable

topic: improve UX by using pager only when we should Before this patch we were using pager in every case of topic command, either it is setting up a new topic or clearing the active topic. After this patch it will not use pager in following commands: $ hg topic [TOPIC] -r [rev] $ hg topic --clear

evolvecmd: _possibledestination() skip visiting empty parent I see that even in the case when "parent == -1" we are visiting that also and find succsets for that and in last -1 is being added in the set of possible destination. Why not skip that?

pick: `hg help` was not showing the full cmd desc of `pick` after running command `hg help` it was not including the second line of command description. I guess it picks the firstline only. So I moved that part in first line of cmd description.

As https://phab.mercurial-scm.org/D3896 has not yet landed, update fixedcopytracing behind a version detection condition. This was spotted by Augie Fackler.

utility: don't translate commit messages in revselection prompt (issue6016) Commit messages should not be translated and should be shown the same. I am not sure if I can add a test for this by creating a commit with non-ascii character in commit message.

evolve: use stack template in --continue case also We use stack indexes (s#) in evolve msging when revs being evolved are in active topic. Before this patch we are not covering the --continue case. So this patch cover the same and use the stack indexes s# even when we continue an interrupted evolve. In this patch I used the same concept (to check if we should use s#) as we are using in cases other than `--continue`. Thanks to PYD for refactoring those lines. Changes in tests also reflects the expected behaviour.

evolve: add test showing currently stackalias fails in --continue case

rewind: alias the command to undo This is a step in unifiying rewind and undo and not talk about them as different commands or concepts. If there exists rewind command, that should be an alias of undo and the vice versa. The exact implmentation detail and how the command works etc. is a different thing but there should be just one command.

changelog: add a line about the usage of s# in evolve

caches: no longer warm the cache on strip in "auto" mode Before this patch, a strip would trigger a full and blind cache load that would include the stablerange cache. In repository like Mozilla this was a bit painful. The default "auto" mode now behave has intended.

evolve: use stack alias s# in `hg evolve` msgs As repository grows revision number lose their usefulness. To make it a little better than now, after this patch we will be using short stack aliases introduced by the topic extension (as displayed by `hg stack`). These stack aliases s# will be used only when user has enabled topic extension and his repo's current active topic is same as the revs to be evolved. For now, this patch doesn't cover `continue` case. I will discuss about this with Pierre-Yves David. Maybe we have to store the info in evolvestate that "we were using stack aliases".

evolve: extract displayer to _solveone() I extracted this displayer method to _solveone() so that it would be easy to pass a different template to show evolve msgs. In upcoming patches we will be using stacktemplate in some cases where we want to include stack alias s# in evolve msgs.

utility: add a template alias that will be used in evolve msgs This template use stack alias s# instead of rev number in messages printed when we run `hg evolve`. For example, this template's msgs will look like this: move:[s3] add aaa atop:[s2] add bbb move:[s4] add ccc I will be using this template in upcoming patches.

topic: add topicidx template keyword This keyword will be useful where we want to see the index of the changeset in the stack when we run `hg stack`.
