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.

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.

evolve: remove not required calls to phases.retractboundary() To make sure phases are preserved during evolve, we started using the phases.new-commit config option. Now we don't need to call phases.retractboundary(). Let's remove the redundant code.

evolve: store the replacements occurred during `hg evolve` at top level This patch starts storing the replacements made during the `hg evolve` command. The current dictionary is not used anywhere but will be used in future as we want to introduce abort functionality, so we want to delay writing of obsmarkers, storing these exchanges in statefile etc.

evolve: make the _solve* functions return a tuple This patch makes _solve* functions return a tuple which will contain information about whether we were able to solve the instability and if yes, then what was the newnode. For more details about tuple, look the fn docs added. There was some refactoring required in next command because of change in return values. This also leds to omitting the wdir update message in case of dry-run which is good.

evolvestate: rename the file to state.py and class name to cmdstate The evolvestate.py and the evolvestate class in it were introduced to help `hg evolve` grow continue and abort options. But the class and it's API can be easily used to store state information for other state files like we stored the information for grab state in the previous commit. Let's rename the the file and class.

update: show "use 'hg evolve' to..." hint iff evolve command enabled Before this patch, one had to enable *all* commands (by including "allnewcommands" in the experimental.evolution config) for the hint to be shown.

obslog: drop period from summary line in accordance with convention

grab: add a command to grab a commit and update to it This patch adds anew command `hg grab` which will pick a commit and put it on the top of the working directory parent and updates to it. Earlier grab was an alias for `hg rebase -r <rev> -d .` which is now deleted to make sure `hg grab` resolves to the grab command and that alias. Continuing interrupted grab functionality is also there using the evolvestate class. Tests are also added for the new introduced command.

amend: query the wdir parent after taking lock (issue5266) If we query wdir parent without taking a lock, that can lead to bugs because the wdir parent can change is another process has changed the wdir parent. One such example of this was issue 5266. When a user is running amend and that amend is waiting for commit message, the user runs another amend which waits for lock. The second amend is waiting for lock, but has already read the description from the parent of working directory to use. Once the first amend completes the wdir parent changes but we still have the description from an old wdir parent. This patch fixes the bug by querying the description after taking lock. Attempts were made to add test for this but the results were unstable because they depend on time in which lock is released.

fold: make sure we move bookmarks after folding (issue5772) The rewriteutil.rewrite() API currently only handles moving bookmark from a old node to new node. In case on fold, we have multiple old nodes, from where a bookmark move is possible. The rewriteutil.rewrite() API is used by another commands also and it's not good to plug in some logic there. This patch handles bookmark movement from all the old nodes to the new node.

tests: add a test showing bookmark not moving in-case of `hg fold` This patch adds a test showing that bookmark is not moved when doing `hg fold`. This test represents issue 5772.

obslog: add header to the changeset description diff This patch adds `diff -r <hash> -r <hash> <filename>` header to the output of the changeset description diff which is shown using the --patch flag of obslog command. This fixes the label/color issue for description diff also.

obslog: colorize the description diff shown in obslog -p This patch colorizes the description diff shown in `hg obslog -p`. The labels for the header are different from that of the patch as the main header which says `diff -r <somehash> -r <somehash> <filename>`. Next patch will hack to add that.

obslog: colorize the patch shown using `hg obslog -p` This patch adds color support to the patch shown in obslog command.

topic: suggest using topic when user creates a new head on branch This patch adds a message to use topics when user creates a new head on a branch.

changelog: update changelog with some of the benefit from the new format

evolve: use better words in conflict markers of `hg evolve` Though we call merge.graft internally, we still have the functionality to pass the words we want to show up in conflict markers. So let's use better words here.

tests: add a test demonstrating we still use graft in conflict markers This patch adds a test which shows that we still use the word graft in the conflict markers. Next patch will start using evolve instead of graft.

evolve: remove the old functions for writing evolvestate Previous patch made all the users of these functions to use the evolvestate class and now they are not required. Let's remove them.

evolve: use the new evolvestate class in place of old methods Earlier we had three methods, which used to handle all the storage around the evolvestate but in previous patch we have introduced an evolvestate class wrapper which can serve for all our needs. This patch replaces the existing usage of the evolvestate with the new class introduced. Upcoming patches will start using the class at more places.

evolvestate: add a class to wrap the state of `hg evolve` command This patch adds a new file which contains a class which will act as a wrapper for the data to be stored or used during the `hg evolve` command. This patch just introduces the file and does not use it at the moment. The upcoming patches will start using it.

evolve: start vendoring third party package cbor This patch adds a third party package named cbor. cbor is a data serialization format and this library provides API to convert Python Objects into cbor formatted data. To know more about cbor, hop onto cbor.io The files are copied from it's official bitbucket repository which is at https://bitbucket.org/bodhisnarkva/cbor/src/113f42203c941470c98f7174065ba9b384cff727/ cbor.py can be found at https://bitbucket.org/bodhisnarkva/cbor/src/113f42203c941470c98f7174065ba9b384cff727/py/cbor/cbor.py # no-check-commit as we are importing a third party package Modified test-check-flake8.t to not lint on thirdparty packages.

uncommit: add a new flag `--revert` to discard wdir changes after uncommit This patch adds a new flag to `hg uncommit` using which one can discard the wdir changes which are left after the operation. Both the changes, the ones which were before the uncommit and the ones which were added to wdir as a result of uncommit as cleared out.

evolve: use phases.new-commit config to retain phase information (issue5720) Since the previous patches replaced the use of graftstate with evolvestate and we don't graft anymore on evolve --continue, we have now the capability to fix underlying bugs. This patch makes sure we use the phases.new-commit config to make a new commit of the same phase as that of the predecessor. Tests added in the previous patch shows the bug being fixed.

tests: add a test demonstarting lose of phase in `hg evolve` This patch adds a new test file which demonstrates the lose of phase information when hg evolve command runs into conflict. This is algo bug5720. The upcoming patch will fix it. A new test file is added as existing test files serve their own purpose and are already cluttered.

evolve: add a utility fn to check validity of opts passed to `hg evolve`

evolve: don't use graftstate for continuing `hg evolve` Before this patch, if user runs `hg evolve`, we read the evolve state, write a graftstate from that information and run graft command. This patch replaces that logic with new logic which does not depends on the graft state. The new logic is very filtered part of logic from graft command. We did not require a lot of opts checking and filtering revs logic from the graft command as our use case is fixed. This is the start of series/work which will make `hg evolve` better and have a good statefile for itself.

topics: add a new templatekeyword `topic` This patch adds a new templatekeyword topic which can be used to list the topic of the changeset when using commands which supports templating.

packaging: update MANIFEST.in to include new tutorial files I forget to update the MANIFEST.in file when important the new tutorial files. This commit fix that.

evolve: use new trouble names in commit messages There is case when we add trouble to the commit message while using `hg evolve`. This match makes sure, we use the new trouble names. The hash changed because it depends on commit messages.

evolve: use compat.TROUBLES to show troubles in user interface compat.TROUBLES is a dict which contains the trouble name for each trouble according to the hg version user is using. All of the replacements are related to `hg evolve` command.

topics: list only topic names in quiet mode This will be helpful in bash completion.

topics: take logic to parse username to a separate function In next patch we will be adding support to `hg stack` to show users, and this logic will be required there too. So let's take it out in a separate function.

changelog: fix a typo in the changelog There is probably many others but that one is fixed now.

caches: switch to 'auto' warming by default This options seems good let us make it the default.

caches: add a 'auto' option for obshashrange cache warming This option will only warm the cache when used as a server.

caches: extract some config reading in 'shouldwarmcache'

caches: pass the transaction to the "shouldwarncache" logic This will allow to have smarter mode about cache warming (eg: only warm them for server transaction.

caches: record 'desc' attribute on transaction This is useful to know if a transaction if server side or not.

caches: protect against missing connection If the connection cannot be established, we should not try to use it.

evolve: don't show working directory obsolete message if we were on it This patch tweaks showing wc obsolete message functionality to not show the message if the operation led us to the same changeset we were on before and it didn't obsoleted it. This make failed updates, update on current changeset and a pull with no change omit showing the message. This has some cons like if you are on rev 1 which is obsolete and you do `hg up <revset>` where revset is some revset which resolves to the rev 1, we won't show the warning as shown earlier.

prev: jump to parent's successor if parent is obsolete and topic is involved `hg stack` shows a linear chain of commits even when they are not linear chain and some changesets are obsoleted and have successors as separate head. This is very nice to have a post evolution view of the stack. However when `hg prev` is run on an unstable changeset whose parent is obsolete and does not topic but parents successor has the topic, it shows no parent on the topic. This patch makes `hg prev` update to parent's successor and make things follow the stack order.

tests: add a test showing wrong behaviour doing `hg prev` on orphan cset If there is an unstable changeset in the topic stack, whose parent is not a part of stack but has a successor which is part of stack, hg stack does shows them in linear order, but `hg prev` on that orphan changset says no parent on that topic. However it should update to the successor of the changeset. It will be fixed in the next patch.

obshashrange: less brutal reset when receiving markers on existing node We now target the affected ranges only. The implementation is still slow but that should be better than what we had before.

stablerange: be more cautious when deleting the sql connection This triggered some crash in further development. This also match what is done elsewhere with this attribute.

stablerange: clarify sql transaction logic This should help concurrent access.

stablerange: use mergepoint based algorithm for the official stable range Changing the official stable range will impact all users of the infrastructure. We update version number of the cache file and discovery methods to clarify this. We do no keep compatibility with the old method over the wire. The new algorithm is much better and keeping compat is more work than we have time for right now.

stablerange: explicitly create a stablerange entry for branchpoint method We are about to change the default.

stablerange: have a mergepoint based sql backed class Everything is so generic that getting a class is 3 line of codes.

stablerange: introduce a sql backed version of the generic on disk cache This is getting use close to actually using the new sorting and algorithm for real.

stablerange: add a base class for on disk stored stablerange class

stablesort: use on disk cache for test

caches: factorise the cache warming check The old conditional was duplicated and hard to read. We factorise everything into the `utility` module.

stablerange: use repo-carried stablesortcache That one is common to all and disk persisted

stablesort: expose the cache through the repository Let have a unique instance, keep it warm and accessible.

stablesort: implement an ondisk cache Persisting the cache on disk will be important for large repositories.

stablesort: realign a misaligned continue We should make a better use of the jump cache now.

stablesort: remove some dead code This closure is no longer in use.

stablesort: abstract all cache access This prepare an on disk version of the cache

stablerange: use first merge cache to skip over linear section If we are to skip over a large section of the range, skipping everything until the first merge seems like a good idea.

stablerange: add a new 'firstmerge' cache This cache store the first merge ancestors of a changesets. This is useful to avoid iteration over the changelog when building stablerange.

stablerange: drop unused `until` utility We no longer needs this function.

stablerange: use cached size data instead of walking the graph Less iteration is better.

stablesort: record previous segment size in the jump That was, we can skip over a full jump without walking it. We'll make use of this in the next changeset.

stablesort: move jump recording inside the exclusive function This will allow use to record to cache size of segment in a later changeset. If the exclusive set is empty, we need to record it outside that function.

stablerange: compute jump size after jump retrieval only This prepares the caching of jump sizes.

stablesort: warm jump cache more efficiently We no longer for a full depth iteration for all request: - we exit early for non-merge, - for merge, we only iterate over the exclusive area.

stablesort: use a regular dict for jumps This will help knowing what revision we have already queried or not.

stablerange: use the jump information for faster iteration Instead of doing a full iteration over the exclusive set, we compare the jump information instead. This perform the same kind of logic than before but will allow for much faster iteration once all the caches are in place.

stablesort: expose the jumps sequence to other code The stable range needs it to build exclusive subrange efficiently.

stablesort: use 'depth' in mergepoint tie breaker The parents with the most depth will is considered lower. It has a couple of advantages. 1) the more shallow parent probably have less exclusive revision, 2) it makes Oedipus merge behave like close to the linear case,

stablesort: rework jump gathering The old code was buggy in some case, the new code give the same result as the 'headstart' version.

stablesort: stop recording jump type There are no mature user of this "jump type" data and the current implementation is known to be buggy. So we drop the logic for now. This will make on disk storage simpler. The data will be reintroduced later

stablesort: pass a jump recording function instead of a list This seems cleaner to abstract the underlying storage to the lower level. This also makes use more flexible about jump detection.

stablesort: minor indent fix

stablesort: clarify subcall to the exclusive side Before doing deeper rework of this logic, we tackle the simplest parts.

docgraph: update test output with new output

stablesort: record, cache and reuse jump Iterating below a merge means two things: 1) iterate over the part exclusive to the higher parents, 2) iterate from the lower parents. While iterating on the exclusive part, there will be case were we just go the next natural parent, and case were we'll have to "jump" to another revision. If we record all point this "jump" happens and their target, we can easily reproduce the iteration in the future. With that information we can iterate over the exclusive part of the merge without having to compute it entirely. In addition we store the reason of the jump. This will help the stable range processing later.

stablesort: fix head start computation The recursion was wrong and provided wrong result. As a side effect, this seems to hint that `stablesort_mergepoint_bounded` is not giving the right result for complex set.

stablesort: avoid attempting to sort a tuple This seems silly.

stablerange: use the filterparents utility

stablesort: use the filtered parents utility

depthcache: use parents filter in depth cache

parents: add a utility to filter parents There is various strange case of merge out there that needs to be handled. We add an utility function to handle them all.

stablerange: abstract the bit able to store cache into sql The part about actually storing the range is independent of the algorithm, so we should extract this before using it for the next iteration.

stablerange: split pure algorithm part from the on disk cache The stable cache file is getting long, we split the logic about keeping data on disk into a dedicated file.

stablerange: add an assert to detect buggy range Nothing can be negative in there, we add an assert to make sure it is so.

stablerange: warn cache for all relevant ancestors range Warming cache in the right order will prevent recursion to happens and unlock usage on large repository.

stablesort: move parent range computation into its own method Now that we have running code, we'll need to avoid too deep recursion. We extract the piece dealing with the parent range before we write more code to warm it.

stablerange: drop the basic inheritance from the 'mergepoint' version All necessary bits are implemented now (except for warmup which we explicitly bypass for now).

stablerange: cache known subrange at the stablerangecached level That way, the 'stablerange_mergepoint' class also benefit from it.

stablerange: use sort cache to build 'mergepoint' information Using the walk cache gives use a better complexity we need to scale. There are further improvement we could make, but this is a good first step.

stablesort: make the iteration from head available to all This will be useful for the stablerange code to work properly.

depth: fix compare mode for `debugdepth` The compare mode was broken for silly reasons.

memfilectx: changectx argument is not mandatory As changectx argument is now mandatory for memfilectx, add a compatibility layer to pass it when necessary. The commit that made the parament mandatory in core is 8a0cac20a1ad

branching: merge with stable

obsnote: warn if user try to store a note in obsmarker on an older hg Support to store a note in obsmarker is from hg>=4.4. We have added notes support to all the evolve commands but we do support versions which don't support storing note in obsmarker. Warn if user tries to store a note in older hg.

topic: use 'hookargs' over 'tr.changes' for flow control The 'tr.changes' attribute do not exists until 4.2.

topic: move function wrapping from reposetup to uisetup Having the function un reposetup means they get wrapped over and over again for long lived process.

genericcaches: handle the lack of util.timer in 4.1 We do the same trick as usual.

topics: fix `hg stack` in case of split This patch fixes the behaviour of hg stack which throws an error in some cases when there are multiple successors. The case of divergence is not handled yet.

changelog: add an entry for the split+branch fix The world needs to know.

branching: merge with stable

split: force the branch to fix the split bug Also restore it after the split

split: add a test demonstrating that split doesn't take the right branch Also add a test to check that the dirstate is in the right state in case the user abort the split.

stablerange: compute the subrange closure on an unfiltered repository This avoid various overhead from filtering.

stablesort: write a flat version of the algorithm This new version never needs to iterate over the full repository even when merge are encountered. Having the algorithm flat also prepare caching works since the iteration sequence can we expressed with a couple of flat loop.

stablesort: simplify processing of non-merge changesets As long as a changeset as only one parent, the next element in the sort (starting from the head) has to be that parent. We detect and take advantage of that shortcut in the non-merge case.

stablesort: extract a '_revsfrom' method Walking from the revision is usually simple unless the revision is a merge. Having this walking logic isolated will help us refine it.

stablerange: use the new cache object in the 'mergepoint' version Every improvement to the cache should reflect on the stable range from there. Since we no longer use the basic sort function, we can simplify the inheritance by dropping one layer.

stablesort: introduce a cache object The object is not caching anything yet, but the API are getting into place.

stablesort: start implementing more advanced version of headstart sorting Now that we can validate the sort with a basic implementation, we can start implementing a version that will support caching and other goodies.

stablerange: make use of the limit argument in 'mergepoint' This will eventually avoid doing full iteration on ancestors of the head when retrieving the range content.

stablerange: introduce a smarte version of stablerange for 'mergepoint' This implementation will using caching and smarter algorithm based on these cache. For now it inherit most of it code from the dummy version for convenience. The inheritance to the dummy version should be dropped eventually.

stablerange: introduce an intermediary abstract class for caching The 'branchpoint' and 'mergepoint' based stablerange class will need similar cache, we introduce an abstract class to take care of that first.

stablerange: introduce a basic-mergepoint method This method use the new 'mergepoint' based stable sorting. It is expected to be eventually better than branch point to stable range: more stable, easier to cache, etc. Having a basic implementation will allow use to validate more advanced implementation.

stablesort: add a new test to check for fully independant branches Apparently, this was not covered.

stablesort: add a --limit argument This will be useful when using stable sort within stable range.

stablesort: introduce a mergepoint based method focused on head The things we needs for stable range is head centric. So we simplify the issue by focussing on head.

stablesort: introduce a "mergepoint" method The mergepoint method decide order from merge. This allow to directly reuse a the full sort of one of the parent, and should simplify caching.

stablerange: fallback to a more naive approach to find subrange As suspected, using "bheads" was bit good enough in some case and we have to fall back to the approach used in "basic". On the evolve repo (about 3K changeset) this approach is about 60% slower than the previous (wrong) code.

stablebranch: avoid overlap between subrange Subrange overlap make things more complicated and less efficient. We fix the computation done in the "cached" version of the stablerange cache. This bring things in line with the result produced by the basic version. Since we already bumped the format version since the last release, I don't things we need to do anything else.

stablerange: introduce an 'basicstablerange' This class hold all the basic of stable range but the part specific to the sorting. This allow to clearly express what is expected from each method and to generate tests output to be validated against the more complex implementation. While writing this, we spotted a bug in the current stable range implementation. Fix coming.

stablerange: extract the core API into a 'stablerangecore' class To clarify what the code is doing without all the caching and algorithmic improvement, we extract a core class that highlight the basic API expected from the class.

stable-branch: setup tests to use a specific method by default This will make future test simpler.

stablerange: rework the debug command to allow for multiple method Similar to what we did for the other debug command related to sorting, we prepare for the arrival of multiple method to produce the result (including simple implementation that are easy to read but do not scale).

deptcache: make sure we warm the dept cache before warming the obsdiscovery The depthcache need to a warmed a bit more agressively

stablesort: add a 'method' argument to the debugstablesort command Let start experimenting with other way to do stable sorting.

stablesort: rename function to stablesort_branchpoint We are about to test different approach to stable sorting. We clarify that the existing method is sorting from branch points.

stablerange: update the filename to avoid cache confusion The schema validation seems to not work as well as intended, we update the file name to make sure there will be no confusion.

stablesort: extract in its own module We are going to introduce variants, cache and more complex logic, we move that in its own repository beforehand.

compat: in depth cache, only use cachevfs when available We support older version without the new vfs.

depthcache: issue a progress bar when loading the depth cache The operation can be in the minute order of magnitude of some larger repository. We better keep the user entertain when he wait.

depthcache: move to a dedicated object and storage The SQL cache was overkill and fragile. We move to a dedicated storage using the new generic class.

cache: adds debug details about what the content of the update Having more data in debug is good, we add a small method to help providing them. This code was headed for core during the 4.3 cycle but never made it there. So we starts with a copy in the evolve repository.

cache: introduce a changelogsourcebase class This abstract class will help code that need a cache tracking the changelog content (eg: the branchmap cache). The cache key used is the same as what the branchmap uses. This code was headed for core during the 4.3 cycle but never made it there. So we starts with a copy in the evolve repository.

cache: introduce an abstract class for cache we can upgrade incrementally Right now each class implements their own mechanism for validation, and update. We start introducing abstract class to ultimately allow more unification of the cache code. The end goal of this series is to introduce a cache for some obsolescence property, not to actually implement the cache. However, taking advantage of adding a new cache to introduce the abstract class seems like a win. This code was headed for core during the 4.3 cycle but never made it there. So we starts with a copy in the evolve repository.

depth: basic debugdepth implementation and test This will come very handy to validate more advanced implementation later.

topics: add a config to reject draft changeset without topic on a server This patch adds a new config option experimental.topic-mode.server which if sets to True, the server won't accept any draft changeset without topic on it. In case both `experimental.topic-mode.server` and `experimental.topic.publish-bare-branch` are set to True, the enforce-topic one is respected. Tests are added for it. The CHANGELOG file is also updated mentioning about the config option.

test: update output to ad5f2b923b0d A new bundle2 capabilities have been added (related to bookmark). So we have to update the test output. CORE-TEST-OUTPUT-UPDATE: ad5f2b923b0d

touch: shorten touch's docstring to make it fit into a one line This make it show completely (untruncated) in `hg help -e evolve`. This follows up on fed946edc293 where the docstring got unwrap for that purpose and thus made the line length exceed 80 columns.

branching: merge with stable

help: promote "amend" to important command Recent change to what command we advertise as "basic". It turn out "amend" was not part of one of them. Since "amend" is one of the core command of a rewriting workflow, we promote it to "basic command".

help: fix output for `hg help -e evolve` wrt 'touch' command Currently, when running `hg help -e evolve`, the output looks like this on my screen: touch create successors that are identical to their predecessors except With this change, it looks like this: touch create successors that are identical to their predecessors except for the changeset ID

help: remove a few commands from `hg` (no args) command list According to `hg help -e evolve`, the following commands come from the evolve extension: amend evolve fold metaedit next obslog pdiff previous prune pstatus split touch uncommit If one runs `hg` without arguments, commands that are prefixed with a ^ character are shown. From the previous list, this includes: evolve fold metaedit next previous prune split touch uncommit It feels several of these commands are not "basic commands" that someone who has never used hg before might care about. They probably also do not come close to passing the "toothbrush test": things that users are likely to use every day. This commit removes these items from the list: metaedit, touch, uncommit This means the following are kept: evolve fold next previous prune split

typos: fix typos in several locations A user at Google attempted to fix our local copy because they had noticed a typo (accross instead of across), but this will just get overwritten on our next import. This commit fixes that case and a few others that my editor found. Most of the typos were in comments, but user-visible output is changed in a few cases: - accross -> across - splitted -> split - ambigious -> ambiguous - evolvestte -> evolvestate (this is in a ui.debug, so not often seen) There is another typo that I wanted to fix, but didn't: 'supercede' is spelled 'superseed' in a few locations. I believe this is only internal to the extension, instead of being user-visible, so while it could probably be fixed easily, I wasn't 100% sure it didn't end up in a file on disk or something and might cause problems, so I left it alone.

topic: use more protective code to access current topic There are some code path where the operation is not properly initialized and lack the new attributes. While the lack of initialization, is suspicious and I've not be able to pin point case where this happens. Currently the code crash when it encounter this situation. So we make the code more resistant to this case to prevent bad user experience.

The UI is not finalised and will be improved in the patches after support is added and we have tests with the current output.

cmdrewrite: add a utility function to make sure note is of valid format Upcoming patches will add support to store a note on various evolution related commands by storing that in obsmarker. Since the obsmarker metadata field can't store things above 255 bytes, this patch introduces a function which will be used to make sure note is under 255 bytes and does not contain newlines. We don't want notes to be multilines.

test: remove dangling --config in test-metaedit.t

tests: fix previously accidentally matching regexes in test-touch.t Before Mercurial commit 6d5718e39657 (run-tests: make "| foo (re)" not match everything, 2017-11-29), regexes like "| foo", which are common in graphlog output, would incorrectly match anything. After that commit, they match as they should, meaning that either "" or " foo" would match, but not a "| foo". This commit fixes the test by replacing the "|" by "." rather than escaping with "\|" since that would make the graph harder to read.

test: update test-discovery-obshashrange.t

serverminitopic: also avoid reading Avoiding to write cache for filter where topic applies is a good step, but we need to also avoid reading it. Existing branchmap cache might exists before the turned the feature on.

changelog: add details about the pushkey related fix

wireproto: gracefully fail on http when trying to use older pushkey method Previously the HTTP server would return a 500. It now returns a 410.

wireproto: avoid exposing pushkey abort for server without evolution Client with evolution enabled will query the 'obsolete' pushley namespace if no other way to request obsmarkers have been found. They will do this unconditionally as long as no other obsolescence related capabilities have been advertised by the server. The call is "harmless" since the namespace will be empty if obsmarkers exchange is disabled. However, since we forbid the use of pushkey for obsmarkers this lead to unexpected crash report for up to date client talking to a server with the evolve extensions but exchange disabled. We fix the issue by serving the expected empty namespace in this case. We keep forbidding the query if obsmarker exchange is enabled since new client should have picked another more effective was to fetch the data first. We also add some tests for this logic.

obsdiscovery: enforce the config on the server too Right now, setting 'experimental.evolution.obsdiscovery=no' disable obsolescence markers discovery on client only. The server still advertise discovery related capabilities. We now also honor the config on the server side.
