evolve: use in code filtered error for 4.6 Things have been upstream into core for a while, let us use them instead of the evolve version.

documentation: refer to 4.3 in the help text Minimal version supported is now 4.3. Drop reference to 4.2 in the help.

topic: remove compatibility for older version in discovery wrapping Support for 4.1 and 4.2 has been dropped.

obscache: drop compat layer to access public changeset We can now access precomputed sets. (compat to 4.1 and 4.2 dropped)

template: drop compatibility layer Support has been dropped for 4.1 and 4.2

timer: drop compat layer for time Support for 4.1 and 4.2 has been dropped.

compat: drop support for Mercurial 4.2 Since Mercurial 4.6 is about to be released, we drop support for 4.2 too. (code still need to be cleaned up).

compat: close test-compat branch for mercurial-4.2 Support for this version have just been dropped.

evolve: add support for hg >= b4d85bc1 Mercurial commit b4d85bc1 deleted the wireproto module and its contents are now in various other modules, so we can not even do unchecked imports of it now.

discovery: handle deletion of 'wireproto' module Mercurial commit b4d85bc122bd. deleted the wireproto module and its contents are now in various other modules, so we can not even do unchecked imports of it now.

evolve: handle wireproto module deletion for registering new commands Module have been deleted in b4d85bc122bd. We can no longer import it blindly.

minitopic: handle wireproto module change from b4d85bc122bd This module have been scattered in other place, so we need to detect and handle this for 4.6+

topic: handle wireproto module change from b4d85bc122bd This module have been scattered in other place, so we need to detect and handle this for 4.6+

obsexchange: remove unused import of wireprotoserver This seems to be unused since 300d7d019b9.

compat: rename resolvepartialhexnodeid to resolvehexnodeidprefix The name changed in 5f8f013e7d52

compat: access datestr in a way compatible with verison prior to 4.6

compat: fallback to compatible partial lookup prior to 4.6

import: adapt to fd1dd79cff20 With the latest state of the code, the patch is passed to "import try one" as parsed.

import: grab the expected node value on the fly We no longer parse the patch beforehand this will reduce inconsistency with newer API.

import: use a less direct approach to store the expected node This will help later refactoring.

compat: adapt `amend --patch` to the new `patch.extract` API

compat: deal with change in the wireproto module

branching: merge with stable

topic: allow '.' in topic names This is also commonly used.

relocate: look up partial nodeids in unfiltered repo This accidentally changed to using the filtered repo in commit 0f0f3135.

compat: avoid using partial node ID in lookup This is getting deprecated in 4.6.

test: apply output change from protocaps CORE-TEST-OUTPUT-UPDATE: afcfdf53e4b5

test: update output to match upstream The exact wording for filtered error has been changed. CORE-TEST-OUTPUT-UPDATE: ecd3f6909184

evolve: don't pass stringified int to repo.__getitem__ We were doing repo['-1'], which is now deprecated. Switch to repo['tip'], which is much clearer anyway (I initially thought this was nullrev and sent an incorrect patch until Pierre-Yves corrected me).

patch: offer the user a chance to fix the patch if it fails to apply The experience is still not great, but better than purely dropping the changes.

amend: add a new flag `--patch` to `hg amend` This patch adds a new flag `--patch` to `hg amend` which pops up an editor with the patch of working directory parent which you can change, and when you exit the editor the patch with changes is applied to current working directory with old changeset being obsoleted in favour of new one created by the applied patch. If supplied filenames, only those filenames are present in the popped editor and rest files stay the same way in the commit as they were. The extension of the file which opens up in editor is '.diff', we cannot have it as '.patch' as there will be develwarns related to that. We need to change to patch core and undo some change to achieve this. The implementation does not use any core API rather it has picked chunks from API which are required. One main reason to not use core import API is that we have to change wdir parent before using patch.patch() which I will like to avoid to make sure we handle merge cases too. While writing this patch I have spend lot of time try to use internal API's to work for this but none of them served the purpose well. If I have time in future and work on similar problem again, I am going to write better high-level API's which uses patchstore to achieve this. A new test file test-amend-patch.t which contains a lot of testing of the feature.

stablerangecache: include units in ui.progress() calls

stablerange: include units in ui.progress() calls

tests: add test demonstarting issue5833 is fixed Previous patch which fixed issue5832 also fixed issue5833 as the root cause for both was same. This patch adds test of issue5833 as well. CHANEGLOG entry is also added for the fixed issues.

utility: convert node from MultipleSuccessorsError to rev numbers (issue5832) utility.builddependencies() deals with rev numbers but MultipleSuccessorsError returns nodeid which breaks the function and also breaks instability resolution. Previou patch demonstrate the breakage. This patch makes sure we convert those nodeids to rev numbers before processing ahead.

tests: add a test demonstarting issue5832 traceback The traceback will be fixed in upcoming patches.

CHANGELOG: add an entry about `hg evolve --abort` Previous patches added a new flag `--abort` for `hg evolve` which aborts an interrupted evolve. Currently this only works for orphan resolution cases which is very common and most people use `evolve` for that. So let's add an entry about that.

evolve: restore bookmarks correctly after `hg evolve --abort` This patch adds logic to store bookmark movements in evolvestate class and restore bookmarks to their original place if `hg evolve --abort` is called.

topic-ext: restrict the format of topic names This patch restrict the format of topic names to make sure they consist only of alphanumeric, '_' and '-' characters.

serverminitopic: wrap context.changectx.branch instead of context.changectx Recently some changes in core resulted in this wrapping of class leading to an infinite recursion. Let's wrap the particular function instead of wrapping the whole command. This fixes test-minitopic.t which was breaking.

templatekw: remove obsfatedata templatekw Individuals fields are available in core as single template functions.

evolve: do not exit 1 when there are no troubled changesets (issue5823) There are possibly other cases we also do not wish to exit non-zero for in this function, but I did not analyze them closely and am just looking at resolving issue5823.

changelog: add an entry about the memory fixes

safeguard: use self instead of repo in noautopublishrepo.checkpush() Referring to repo here was somehow preventing it from being garbage-collected (important in hgweb, where currently every request gets a new repo).

stablerangecache: use self instead of repo in stablerangerepo.stablerange() Referring to repo here was somehow preventing it from being garbage-collected (important in hgweb, where currently every request gets a new repo).

obscache: use self instead of repo in obscacherepo.updatecaches() Referring to repo here was somehow preventing it from being garbage-collected (important in hgweb, where currently every request gets a new repo).

templatekw: fix templatedata for 46

style: fix a couple of pyflakes complains

evolve: add a `--abort` flag for `hg evolve` command This patch adds a new flag `--abort` to `hg evolve` command which will abort the interrupted evolve going on undoes the changes created by the evolve command till now. The changes are bookmark movements, creation of evolved commits, obsolete the old commits in favor of evolved commits. In case when user changed things while the interrupted evolve, like did some actions which created a new commit on top of evolved commits, or changed phase of evolved commits to public, the evolve fails to abort as we should not strip out the new commit formed by user neither we can strip the public changeset. The abort fails and tell user to use `hg evolve --stop` instead. Right now bookmark movement is broken, and will be fixed in upcoming patches. Tests are added for the new flag.

evolve: don't allow updating or commiting when there is interrupted evolve We should make things simple in the starting and restrict user from doing things which can lead to problems. This is same as the rebase behavior.

evolve: internationalize the entry of --list in hg evolve help

evolve: add evolvestate as an argument to _finalizerelocate() This will help us to store bookmark changes to evolvestate to revert them in case when `hg evolve --abort` is called.

evolve: add evolvestate as an argument to evolvecmd.relocate() This will help us in passing it to _finalizerelocate() and store the bookmark changes which happend.

tests: add test about handling phase-divergent merges We don't handle phase-divergent merges and we should. Upcoming patches will add the ability to handle them.

evolve: show a message when evolution leads to no changes to commit In case of orphan resolution, evolution may result in no changes to commit. This patch adds a use message in such cases. This is same as the rebase behavior.

evolve: pass the instability category to relocate() and _finalizerelocate() This patch adds category argument to relocate() and _finalizerelocate() functions to take the type of instability which we are processing so that we perform actions accordingly.

tests: add more tests for solving phase-divergence using `hg evolve` This patch adds more tests for resolving phase-divergence caused due to fold or split using `hg evolve` command. The resolution in case of split is not very good and will be fixed in upcoming patches

evolve: handle interrupted phase-divergence resolution gracefully This patch adds logic to handle the interrupted phase-divergence resolution by `hg evolve` command gracefully. We first complete the relocation of the changeset and then do the divergence resolution. Previous functions moved required code separate fucntions so that we can use them here.

evolve: move logic to resolve phase-divergence in a new function This patch moves logic which does the revert and create a commit on top of public changeset because we need to repeat that logic while handling continuation of `hg evolve` when there are conflicts while rebasing the phase-divergent changeset.

evolve: store the precursor of phase-divergent in evolvestate This patch makes `hg evolve` store the precursor of phase-divergent changeset in evolvestate so that we don't need to calculate that again.

evolve: move logic to complete interrupted relocation to new fn This moves logic which completed the interrupted relocation to it's own separate function as we will need that function in continuing phase-divergence and content-divergence too.

evolve: move logic to complete interrupted orphan resolution to new fn This patch moves logic which completes an interrupted orphan resolution to it's own new function. We will defining such functions for completing phase-divergence and content-divergence too.

evolve: write data to evolvestate in case on conflicts in phase-divergence This patch makes phase-divergence resolution write data to evolvestate instead of graftstate. The `evolve --continue` handling of phase-divergence is broken which will be done in upcoming patches.

evolve: explicitly turn revs to list before storing into evolvestate The cbor library which we are using cannot handle encoding and decoding Python sets, and revs was set there. Let's convert revs explicitly to list to make sure we don't try writing sets.

tests: add tests of content+parent change creating phase-divergence This patch adds tests which shows handling of phase divergence cases by `hg evolve` command which involved content+parent change. The conflicts case is not handled and will be fixed in upcoming patches.

tests: show first line of commit message in test-evolve-phase-divergence.t This patch adds 'firstline' filter to description in the log template.

evolve: make sure bookmarks are moved after phase-divergence resolution This patch adds logic to move bookmarks from the rebased node to the phase-divergence resolved node.

evolve: use the new rebased changeset to resolve phase-divergence When there is a parent change in phase-divergence, `hg evolve` first rebases the diveregent changeset on parent of public changeset and then continue the resolution of phase-divergence *but* we used to continue with the old divergent changeset rather than the new rebased one. This patch makes sure we use the new rebased changeset to proceed with the resolution. Tests changes shows that it fixes things which were broken earlier.

evolvecmd: add a detailed comment and some newlines This patch adds a detailed comment on a chunk and some newlines to make things look better and more understandable for upcoming patches.

tests: add one more test case about handling of phase-divergence by evolve This patch adds a test case when phasedivergence is caused by rebase command and there is parent change involved. As the tests show, we are not handling things correctly here. Upcoming patches will fix that. Fixing things in later patches showed there was a wrong case in one another test which will be fixed by later patches, so let's add description on why that test is wrong in this patch.

tests: add more tests for handling of phase divergence by `hg evolve` This patch adds more tests related to handling of phase-divergence by `hg evolve` command.

tests: temporary delete the merge test of handling phase divergence This patch temporary deletes the merge test of handling phase divergence by `hg evolve` command to that other important tests can be plugged in before this. This will make adding more tests easy. As I say, this is temporary to ease out adding more tests, the test will be added back.

tests: various comment on test-evolve-phase-divergence

tests: make test-evolve-phase-divergence more descriptive This patch adds description to what each part is doing in test-evolve-phase-divergence.t and some commands which should be used to analyze the divergence before resolving that.

compat: use updateresult API if available The status return is no longer a tuple, we access attribute instead.

compat: provide an explicit default value to the 'odiff' config There is a devel warning about this now.

compat: keep passing arguments as keyword argument Otherwise, This break with new changes in upstream Mercurial.

compat: search for stringmatcher in the new location More of util has been split into sub modules.

rebase: update the rebase wrapping to works with hg 4.6 Mercurial core commit bd0086bd3af4 removed _makeextrafn hence breaking our wrapping. Update the code to wrap rebaseruntime directly in a way that's compatible with hg 4.1+.

compat: call current obsolete.createmarkers(), not one from load time Other extensions may wrap obsolete.createmarkers(). If they do, we should call their wrapped version. However, since f61a23a84dac (compat: add wrapper for obsolete.createmarkers() that accepts "operation" arg, 2018-03-16), we started storing the version of the function as it was when our compat module was loaded. This broke an extension we use internally at Google.

tests: rename test-evolve-bumped to test-evolve-phase-divergence.t While I was here, I added a heading to test mentioning what the test if for.

evolve: replace bumped in function name to phasedivergence bumped was the old name of phasedivergence. Lets replace with its new name so that we can forget the old one.

evolve: drop duplicate import of rewriteutil._bookmarksupdater

obslog: more 4.1 code compatibility drop

template: drop some 4.1 compatibility code Simplify all the things.

checkheads: drop upstreamed code Mercurial 4.2 has all the code that used to live in the evolve extensions so we can drop it now.

obslog: cleanup patch handling after 4.1 compat drop We can remove some of your compatibility code.

packaging: further mark 4.1 support as dropped

branching: merge with stable

tests: extend the globing to the user name Silly me.

branching: close mercurial-4.1 test branch

evolve: kill `--obsolete` and `--old-obsolete` flags for graft Evolve extension used to add the couple of flags to `hg graft` command for reasons I don't know but they were deprecated. For the functionality of `hg graft --old-obsolete`, we have `hg grab` now which can do that. One more reason to kill this is that we have logic to parse the graftstate, whereas in core, we are going to change how state files are read and write. Tweaked the tests a bit to use `hg grab` instead of these flags to make rest of the test output consistent. Replaced an entry of `hg graft -O` in doc by `hg grab`.

compat: drop support for Mercurial 4.1 This version is over 1 year old and we are dropping support for it.

packaging: mark versiond as devel versions This will help prevent confusion when installing a non-tagged version.

packaging: merge stable back into default Version have been released.

packaging: mark version as devel version This will help prevent confusion when installing non-tagged version.

__init__: show some internationalization love

evolvecmd: show some internationalization love Some outputs are not internationalized because I doubt that they are gonna stay here for long.

utility: make sure prompt text is internationalized This patch internationlize the prompt text by passing the into mercurial.i18n._

test: do not use revision number This get confused with older version.

compat: use mergetoolopts from commands.py Mercurial <= 4.2 do not have cmdutils.py yet.

branching: merge stable into default Some bugfix that we could use here (also getting ready for a release).

evolve: add a `--stop` flag for `hg evolve` command This patch adds a `--stop` flag for `hg evolve` command. The stop flag lets you stop the evolution from where you are and let you move to other things if you want. This fuctionality is great as user can decide to resolve conflicts later on, stop the command execution, do something else and get back once they has time or care about resolving them. As implementation details, it clears the evolvestate, updates to the parent of working directory clearing the uncommitted changes which also deletes the mergestate. A new test file test-evolve-stop.t is added with tests of the new flag added.

obsexchange: make compatible with some unreleased 4.5 versions We don't generally care to be compatible with unreleased versions of hg, but this is just a one-line change to be compatible with a range of commits before 158d4ecc03c8 (wireprotoserver: move all wire protocol handling logic out of hgweb, 2018-03-08), so hopefull it can be worth it.

compat: make override of createmarkers work on wrapped function If createmarkers() has been wrapped using functools.partial(), the __code__ attribute won't exist. Fix by unwrapping partial functions. I tried to find another attribute to use as proxy for the "__code__.co_argcount < 6", but there were no new functions or similar added in that commit.

previous/next: add -m short form for --merge This matches core's option to `hg update`. This patch also covers `hg next`, but test-check-commit.t only lets me mention one of them.

evolve: handle stabilization of merge changeset with both parents obsoleted This patch adds logic to stabilize an orphan merge changeset having both parents obsoleted. The logic tries to first stabilize the merge changeset on successor of second parent and then stabilize the new changeset formed on the successor of first parent. We are stabilizing on second parent first and then to second parent to preserve the first parent's successor as first parent of the merge changeset. Conflicts can occcur and we can loose processing information, therefore we store a variable in statefile `orphanmerge` which represents whether we are processing a merge changeset with both parents obsoleted. Thanks to Pierre-Yves David for suggesting this way and helping to understand the correctness of this. More rigourous test cases for this will be added in next patch.

state: add __setitem__() for cmdstate class Adding __setitem__() will help us in setting the value of variables stored in state files using `state[key] = value` in our code which is very convenient.

evolve: preserve the order of merge parents in `hg evolve --continue` This patch makes sure we preserves the order of merge parents in case of `hg evolve --continue`.

topics: include "operation" metadata in obsmarkers

grab: include "operation" metadata in obsmarkers

touch: include "operation" metadata in obsmarkers

split: include "operation" metadata in obsmarkers

prune: include "operation" metadata in obsmarkers

metaedit: include "operation" metadata in obsmarkers

fold: include "operation" metadata in obsmarkers

uncommit: include "operation" metadata in obsmarkers

evolve: include "operation" metadata in obsmarkers

amend: include "operation" metadata in obsmarkers This is for the legacy handling support for "hg commit --amend" case. I picked "amend" because it feels more natural than "commit". Besides, and more importantly, that's consistent what core uses.

compat: add wrapper for obsolete.createmarkers() that accepts "operation" arg I want to start passing the operation argument, but hg < 4.3 does not support it, so we need a compat wrapper. For older hg, the operation is simply ignored.

tests: do not glob out fixed dates Perhaps these dates historically have not been fixed, but they seem to be now. I got tired of not being able to use "run-tests.py -i".

evolve: de-duplicate some function calls _cleanup() was called in continueevolve() and evolve() function too. Let's call it at a single place for both the cases. Also call progresscb() outside of conditionals to call it both times.

evolve: move deletion of evolvestate out of continueevolve() function We need to extract some data at evolve() function from evolvestate.

evolve: load evolvestate before passing to continueevolve() This patch moves some code from continueevolve() to evolve() function so that we have a loaded evolvestate present in the evolve() function for post processing.

evolve: move the handling for non-continue part in else conditional This will help us do factor out which operations we want to do for continue, which for non-continue and which operations we want to do for both of them.

evolve: move the logic of continuation handling of `hg evolve` in own fn The function which defines the evolve command is pretty big with all the logic messed up there. It's better to have individual functions for individual uses. The movement of code will help in adding more logic to continue part in clean way. Moreover for implementing `hg continue`, we need all continuation handling in their own functions, so it will help there too.

CHANGELOG: add an entry about next and prev being interactive

prev: show changeset hash in --dry-run instead of rev numbers rev numbers can change, so it's better to show changeset hash.

prev: prompt user to choose parent in case of multiple parents This patch adds functionality to `hg prev` to prompt user to choose one parent to update when multiple parents exist. Surprisingly there were no tests for this case before this patch, I added one with this patch.

next: cleanup logic around return by returning early In the cmdnext function, there are some conditionals which returns early and some which sets a result value to be returned later. Let's return from all the conditionals early. There are if, elif and else involved, so it's sure we will end up in one of the conditional, each conditional will return, so it's guranteed that we are returning the correct value and returning everytime.

next: prompt user to choose child in ambiguity in `hg next --evolve` This patch makes `hg next --evolve` prompt user to choose a child to evolve and update when multiple of them exists. This is improvement over previous behavior where we used to error out saying ambiguous next unstable changeset and told user to manually use `hg evolve -r rev`. While writing this patch, I am personally very happy to have this feature as I have encountered this stage many times and I wanted `next --evolve` to take care of that. It uses the revselectionprompt thing added in earlier patches.

next: move logic to evolve the children to it's own function This patch moves the logic which evolves the children and updates to it in `hg next --evolve` to it's own function as we want to use that again.

next: prompt user to choose a children in case of ambiguity This patch adds functionality to prompt user and ask the children to which next should move to incase of multiple childrens. This is a very nice UI because otherwise user has to lookup changeset hash, and then manually do `hg update` to that. In this case we show hash and description so user can choose which one to update easily. It is using the interactive revision choosing functionality added in a previous patch.

next: show changeset hash in `--dry-run` instead of rev numbers Rev numbers can change, hence we should show rev hash instead of rev numbers in dry-run.

evolve: make sure we consider all cases in if-else The part of code which is touched decides on evolution of merge changeset. We need proper handling of each case there, so before adding logic, let's add conditional for each case so that upcoming patches are easy to understand.

tests: add more cases about stabilization of an orphaned merge commit This patch adds three more cases related to stabilization of orphaned merge commits.

evolve: fix missing negation Spotted by Pulkit Goyal.

evolve: clarify message for ambiguous destination from split Message is a bit long, but should be less scary.

evolve: prompt user to select destination for stabilization in case of split This patch adds functionality to prompt user to select a revision when there exists multiple stabilization destination because of split on multiple branches. Test are also added for the feature. I am not sure whether this is the best message which we can show, if people have suggestions I will like to improve the messages shown in prompt.

tests: remove some tests which are moved to dedicated files The tests in test-unstable.t files are now moved to their dedicated file with all the cases to that in that file. Let's delete them from here.

next: factor out the logic to update to changeset in another function This patch moves the logic to update to children changeset during `hg next` in a separate function because we want to re-use the logic when we will prompt user to choose a changeset in case of multiple childrens.

utility: add a function to prompt user to choose a revision This patch adds a utility function to interactively prompt user to choose a revision to proceed in cases when there are multiple revisions which are candidates. The function will be used in `hg evolve`, `hg next`, `hg prev` etc. If user feedback will be good, I plan to move it to core and use it at more possible places.

tests: add a test about evolve stabilizing orphan caused by splits There are some similar tests lying around in the test suite but they are not well arranged. I wanted the test suite to be a goto reference for all the behaviors till the time we get all of them documented.

test: fix output after rev-branch-cache has been merged Mercurial core 2090044a288d added a new revbranchcache part which changed some exchange-related outputs. Glob them to ease merging with old Mercurial versions branches.

cleanup: remove duplicate import of "obsolete"

previous: fix behavior on obsolete cset when topic is involved (issue5708) This patch fixes the behavior of `hg previous` when done on an obsolete changeset having a successor of different topic. The underlying code is bit messed up, I wanted to split the topic handling to topic extension but I have postponed it to next bug.

previous: add test case when it's broken on obsolete cset This patch adds couple of tests showing `hg previous` is broken on obsolete changeset when the successor has different topic. Upcoming patch will fix this.

prev: fix the breakage of `hg previous` from obsolete cset This patch fix the breakage of `hg prev` from obsolete changeset when topic is involved. We get the topicidx of it's succesor and proceed.

prev: add a test case which shows traceback when doing prev on obsolete cset This patch adds a test which shows how `hg prev` is borken when called from a obsolete changeset and there is an active topic. The next patch will fix that.

tests: add more tests related to stabilization of orphaned merge commit This patch more tests related to stabilization of orphaned merge commit. Stabilization of a merge changeset with both the parents is not supported right now and prints a message on how to do that. Maybe we should do that internally as a part of `hg evolve` but I need to think about this.

evolve: fix stabilization of orphan merge changesets in case of conflicts As demonstrated by tests added in previous patch, if one of the parent of a merge changeset has a new version and merge changeset gets, running `hg evolve` to stabilize that if results in conflicts will lead to lose of other parent of that merge changeset when we resolve conflicts and do `hg evolve --continue`. This patch fixes the behavior, by checking whether we are continuing evolving a merge changeset and if yes, setting the dirstate parents according to that.

tests: add a test file of resolving orphaness of merge changesets This patch adds a new test file named test-evolve-orphan-merge.t which contains test cases when `hg evolve` try to stabilize a merge changeset which was orphan. This file contains 20-30% of all the cases as we have got something to fix before we add tests for rest of the cases. Going by this approach will make sure we don't live unfixed cases in the test file and the test files does not become a pile of hacks which are used to get in state when we fix the bugs.

grab: gracefully handle the case when we try to grab parent of wdir Before this patch, we go all the way down to obsmarker creation logic and gets an error saying that changeset cannot obsolete itself. We should be more smart here and error out early saying we cannot grab that changeset.

grab: move the initialization of pctx variable outside of if-else The pctx variable is used outside of the if-else but it was initialized under the conditional statements. Added test for the case when the initialization inside the if-else broke `hg grab --continue`.

compat: drop hack around http request handling for 4.6 The approach we used in 4.5 works again :-)

obsdiscovery: add compatibility layer to register wireproto command Mercurial core 0b18604db95e changed the way permissions are registered.

compat: pass all hgweb dispatch argument to the orig function This make use compatible with whatever changes on this side.

grab: add short version for continue and abort

obsdiscovery: include units in ui.progress() calls (issue5773)

tests: commit tests changes missing in the previous changeset (guess who forgot to amend)...

obslog: add the operation to the Obslog output The operation is helpful when debugging a case where we don't know how we ended up in this case while effect-flag are useful to understand what semantic changes happens to a changeset. Add the operation when displaying an obs-marker in the following form: `rewritten as X using amend` The other proposal is interesting but seems harder to internationalize and might requires update each time we introduce new operation: `Amended as X` Let's use the first proposal right now.

serverminitopic: attempt to fix assertion for repoview in branchmap This seems fine since we topic never impact public only caches.

compat: register a version of 'obsfatedata' template that works with 4.6 Since showlist is deprecated, let us use compatlist.

compat: register a version of 'troubles' template that works with 4.6 API Since showlist is deprecated, let us use compatlist.

exthelper: add support for "requires" argument for template keyword This will help use to support the new template API.

compat: add compat layer for date related functions

branching: merge with stable

compat: more straight forward alias for old template names The template registration have significantly changed in core:7b74afec6772. We take simpler approach to define the alias in a way that works for all versions.

serverminitopic: fix wrong object being passed to phase

legacy: respect explicit config for server.bundle1 Unconditionally disabling bundle1 is a problem for larger hosting website. We adopt a less aggressive approach and only disable it the default would be used.

branching: merge with stable

compat: only wrap wireprotoserver function if they exist Older version does not need the wrapping so everything should be fine.

pure: make sure what we expect to be list are list In the pure version, some of these object would be generator.

evolve: update code for not implicitly converting ctx to revision Mercurial core 38f480502043 removed the capacity to implicitly convert contexts to revisions using `int(ctx)`. Update Evolve code to explicitly call rev instead.

legacy-push: fix the code forbidding legacy obsmarkers pulling changeset e69e65b2b4a9 in code remove a key try/except. We reintroduce it for compatibility.

updatecaches: handle any new parameters to the method

evolvecmd: fix broken `evolve --continue` ran after `next --evolve` Recent series broke `evolve --continue`in cases when run after `hg next --evolve`. The previous patch adds test demonstarting the broken behaviour, this patch fixes that by storing the command which leads us to evolve --continue in the evolvestate.

tests: add test showing `evolve --continue` after `next --evolve` is broken Recent series fixing `hg evolve --continue` break the continue functionality after a conflicting `hg next --evolve`. This patch adds a test to demonstrate that. It will be fixed in the upcoming patch.

color: add some colors to evolve command itself

wireproto: fix *_capabilities for change of API types Mercurial commit 2f7290555c96 introduced new types for *_capabilities, update the code to use them.

obsfate: fix changeset description diff computing Mercurial core 8b6dd3922f70 changed the mdiff.unidiff API. Add a new compat method for all supported Mercurial versions.

evolve: add comptability to read old evolvestate files When a user runs `hg evolve` with old evolve where we used to write evolvestate the old ways i.e. without using cbor, and faces conflicts, the evolve is interrupted. If the user updates evolve before completing the evolve, that can result in traceback as the new evolve cannot read the old evolvestate file. The previous patch added function to read old evolvestate file and this patch uses that when we encounter the above mentioned case.

state: bring back the function to read old evolvestate files Before introduction of this nice cmdstate file wrapper, we had individual methods to write data to evolvestate file. Let's bring back the function which used to read data from the old evolvestae file so that we can use it in next patch for BC purposes.

evolve: add entry in CHANGELOG about fixed behavior of `hg evolve --continue`

evolve: store the skippedrevs in evolvestate While doing `hg evolve`, there are some revs which are skipped as they can't be evolved. Before this patch, we did not store this information in evolvestate and neither they were evolved, so `hg evolve --continue` will again try to stabilize those revisions. As much time as we run `hg evolve --continue`, this will happen which is not a good behavior. This patch adds a skippedrevs list to evolvestate where we store such revisions so that we don't try to stabilize them again.

evolve: show the updated working directory after `hg evolve --continue` `hg evolve` shows a nice message about the new working directory when the evolve ends but if the evolve is interrupted by conflicts and you continue the evolve resolving the conflicts, that nice message is lost. Let's have that in case of `--continue` too.

evolve: make `hg evolve --continue` respect `--confirm` Previous patch added capability to `hg evolve --continue` to continue the rest of the stack, not just the current revision but that was missing respecting the `--confirm` flag which user passed earlier. This patch makes sure we respect the `--confirm` flag.

evolve: make `--continue` continue evolving all remaining revisions This patch makes `hg evolve --continue` to continue all remaining revisions instead of just the current conflicted one. There are some still improvements required to this behavior after which the CHANGELOG entry will be added.

tests: add more tests to test-evolve-continue.t This patch adds more tests for `hg evolve --continue`. The tests demonstrates how the continuation handling of hg evolve is broken and the later patches fixes that handling.

evolve: handle case when newnode can be None while continuing evolve There can be case when `hg evolve --continue` is run, when working directory is clean and there is nothing to be included in the new commit. Let's make sure we handle such cases correctly and obsolete the node which is evolved with parent of wdir as successor. This is same as what rebase does.

tests: add tests for `hg evolve --continue` This patch adds a new test file containing tests for `hg evolve --continue`. The test file still does not contains all the tests related to `hg evolve --continue` as one of the case is broken which needs to be fixed first. The case is when resolving a conflicting evolve results in empty wdir. Next patch will fix the traceback and then a later patch will add more tests.

merge with stable

CHANGELOG: add an entry about resolve showing how to continue evolve

test: explicitly run HGEDITOR shell command with `sh` Otherwise Windows pops up the "What program do you want to use to open this?" dialog.

test: conditionalize blackbox output for Windows

branching: merge with stable

compat: add wrapper for logcmdutil functions These classes and functions were bulk-renamed at hg c8e2d6ed1f9e.

evolve: store the revs to be processed in the evolvestate This will help us in getting a full functional `hg evolve` where `hg evolve --continue` does not only continue one changeset.

evolve: store the replacements in the evolvestate This will greatly help when we will be implementing `hg evolve --abort`.

evolve: store the target category in evolvestate

evolvecmd: use the evolvestate object passed as argument in _solveunstable Earlier if get a merge conflict, we used to initialize a new evolvestate object and used to save it. Let's start using the state object which we get in as argument as that will contain more data about the state.

evolvecmd: pass evolvestate object to _solve* functions This patchs adds an argument evolvestate to _solve* functions. This will help us in having one evolvestate object which we can pass around various functions and keep storing what's going on.

evolve: create a state object in all case Let's create a state object even when we are not in the continue mode. This will help us passing the state object to rest of the functions.

branching: merge with stable

grab: preserve phase of the grabbed changeset This patch fixes the wrong behavior of loosing secret phase of the grabbed changeset.

tests: add a test showing grabbing of secret changeset turn it into draft This patch adds a test showing wrong behavior of `hg grab` command which looses the secret phase while grabbing a secret changeset.

grab: add grab info to cmdutil.afterresolvedstates This will help us in showing how to continue the grab when user resolves all the conflicts.

evolve: add evolve info to cmdutil.afterresolvedstates Adding evolve info to cmdutil.afterresolvedstate will improve the ui when we run into merge conflicts while evolving. Once we resolve all the conflicts using `hg resolve`, this will show a message saying "continue: hg evolve --continue". Other extensions like rebase and shelve also use it and it's very helpful.

doc: add link to roadmap Add a link to the Evolution roadmap in the main page of the documentation.

evolve: move the evolve command to evolvecmd.py This patch moves finishes the code movement by moving the evolve command to evolvecmd.py.

evolve: move _orderrevs() function evolvecmd.py _orderrevs() is a function which is used to order the revs in which the instability needs to be solved if we have multiple revisions to resolve.

evolve: move builddependencies() and _singlesuccessor() to utility module The builddependencies() and _singlesuccessor() function are very useful functions and can be used at a lot of places. They are also used in topic extension also, so let's move them to utility. However moving them to utility won't help anything in the topic extension.

utility: move MultipleSuccessorsError from __init__.py The MultipleSuccessorsError is required in multiple modules in upcoming patches, so let's move it to utility first.

evolvecmd: move more core from __init__.py to evolvecmd.py We are done with moving helper code, we will now be moving the evolve command in the new module.

evolvecmd: move code from __init__.py to evolvecmd.py

evolvecmd: move more code from __init__.py to evolvecmd.py We are now very close to have most of the evolve related code in evolvecmd.py.

evolvecmd: move more chunks of code from __init__.py to evolvecmd.py

evolvecmd: move more functions from __init__.py to evolvecmd.py If things are looking ugly, hold on.

evolvecmd: introduce a new module to handle `hg evolve` related code __init__.py is to cluttered with wrapping and all, it's better to move code related to evolve command to new a module which will help us in great refactoring and introducing nice and better flow of data through functions. There is a temporary import cycle is introduced which will be fixed in the series.
