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

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.

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.

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.

compat: work around the lack of configoverride in mercurial 4.0 The phase preservation will stay broken on 4.0 and below

compat: add an abstraction for 'scmutil.cleanupnodes' The usage of the function was added in 103244e34a9c but is not compatible with Mercurial <= 4.2.

compat: conditionally access config item Version 4.2 and below do not have config items support. So the extensions helper do not register anything.

compat: handle version where obsutil is not available Version older than 4.3 is do not have the obsutil option. We need to handle that.

test: use node instead of rev in topic push tests This makes the test more stable when revision number changes.

test: use node instead of rev in uncommit -i test This makes the test more stable when revision number changes.

branching: create the mercurial-4.3 test compatibility branch This branch will contains the expected test output with 4.3.

branch: merge with stable to prepare 6.7 release In addition, Mercurial 4.4-rc is out, so we need to update the expected output.

changeloge: add details about topic-mode

effect-flag: remove wrapping of createmarkers for Mercurial 4.4 Now that effect-flag has landed in Mercurial 4.4, we don't need to wrap createmarkers for this version anymore.

stack: order the adjective of changeset The new order give more interesting result: * base current * base unstable * current unstable It seems more harmonious this way. Base seems the most core and immutable adjective describing the element. Then current is a volatile but important one. Finally, unstable is less information than current, so it goes last.

stack: show current and unstable also for t0 and bases

obsfate: use core version of obsfate if available Let us use the upstream version whenever available. The operation display is currently disabled to ease with the test changes.

topic: register config items There is a couple more hoops to jump through but all config items used are now registered.

directaccess: register config item if possible Mercurial 4.4 warns about unregistered config.

evolve: registed configitems if available The config are registered as 'dynamicdefault' because we still need to explicitly pass the config option for older version of Mercurial. (4.2 and before).

inhibit: compatibility with 4.4-rc

branching: merge with stable Merge with the inhibit fix.

inhibit: respect '--keep' when handling rebase clean up

test: adapt to change from 537de0b14030 If we use phase for pull/push this impact some debug output. CORE-TEST-OUTPUT-UPDATE: 537de0b14030

test: adapt to output change from eb586ed5d8ce Core have a more verbose output on pull. We have to update tests with it. CORE-TEST-OUTPUT-UPDATE: eb586ed5d8ce

compat: fix compatibility with new duplicatecopies Changeset 754b5117622f updated the signature of 'copies.duplicatecopies'. We can now handle the multiple version of that code for compatiblity.

topic: remove 'ass' from the random animal list As much as I love donkey… this generate inappropriate names.

config: stop passing useless default value to config

branching: merge with stable

changelog: add about fixed bookmark and phase handling while changing topics

changelog: add about pager support

pager: add support to `hg evolve --list`

pager: add support to `hg obslog`

pager: add support to `hg topic`

pager: add support to `hg stack`

pager: add a function in compats to start pager This will help us enabling pager when ui.pager API exists. Also we can try plugging in the old pager API in this function and we won't have to change anything.

metadata: cleanup metadata file I'm not sure how this conflict marker survived the pre-publish test run...

branching: merge with stable

topic: remove a silly duplicate in a revset Spotted by Pulkit Goyal. More performance win seems to exists here, but we starts with the obvious.

topics: show changesetcount, troubledcount and headscount by default

topics: use stack.stack() instead of stack.stackdata() stack.stackdata() also calls stack.stack() internally. Moreover if we just want to calculate changesetcount, troubled count, it will be cheap to calculate using stack.stack rather than stackdata().

packaging: mark version as bugfix dev version This avoid confusion when installing non tagged version.

branching: merge with stable

Added tag 6.7.1 for changeset 430ad68292d7

obslog: remove the word "yet" from "No patch available yet" "yet" was a bit confusing as it let me think that patch is currently not available but can be available sometimes later. This is true for cases when it says "context not local" but we have more messages like "no successors", "too many successors", "changesets rebased" where we can't have a patch.

obslog: spell out successor completely If the successor is not known locally, obslog says `succ is unknown locally` which is not a good message. This patch makes sure succ is spelled out completely as successor.

readme: update readme with latest fix (also more the stack one in the right location).

obsfate: make the user list more readable Separate each user in the obsfate user list by a space for readability.

obsfate: fix user filtering in obsfate-printer Only hide current user only if it's the only one that create obs-markers.

obsfate: add a test with user both current and other This will help highlight change in the next changesets.

obsfate: update test The obsfate templatekw and the obsfateprinter behavior was different when displaying or not the current user in obsfate users. Update the test to makes the behavior fix more visible.

packaging: prepare version 6.7.1 The are an important fix on evolve and another important fix for topic performance, let us make a release.

readme: add changelog for topic 0.3.1

add mention of the topic 0.3.0 version

readme: fix evolve 6.7.1 entry

topic: reorder revset for faster evaluation When running the revset on unfiltered repository, the mutable set can get huge. So removing the obsolete changeset first provide a large speedup. This resolve the performance regression we were seeing since the 6.7.0 release.

topics: use stack rather than stackdata when one only wants the changeset count There might be a significant performance impact. Might resolve #309.

log: update obsfate output order Always display successors after the verb. So instead of "rewritten by boris as X", display "rewritten as X by boris". 07b9fcf8b6d3 did update template-based obsfate but forget to update obsfatelineprinter.

test: remove bashism in test-topic-change.t The test was broken on various machine using shell not supporting the `{start..end}` construct.

topics: handle phase correctly while changing topics

tests: add test showing change of phase while changing topic on secret commit

topics: use scmutil.cleanupnodes to create markers while changing topics Earlier if we change topics on changesets with bookmark, the bookmark is not moved to the new changeset as we didn't add that logic and we were creating obsmarkers directly. This patch calls scmutil.cleanupnodes to create obsmarkes which also handles the bookmark movement.

tests: add a new test for testing changing or clearing topics test-topic.t is getting bigger and bigger. This patch introduces a new test which includes test for clearing and changing topics. Since the tests are moved to a new file, this patch, removes those tests from test-topic.t also.

obscache: do not check of argument count of wrapped function After talking with the original author of this check, it appears that it never worked properly, since _readmarkers was always wrapped with @util.nogc.

legacy: rename lookup_errors to not be in all caps (flake8 warning) flake8 has a plugin, pep8-naming, which is not installed by default, but is used if available, no extra config required. This plugin checks names of variables, classes, functions and so on against PEP-8, and it complained about this variable: N806 variable in function should be lowercase Since this isn't a module-level constant, but just a helper variable used only in one function, it's fine to just rename it. With this error gone, flake8 output (used plugins: mccabe, naming, pycodestyle, pyflakes) is totally clean.

randomname: fix the header of the file

topics: move README-topic as hgext3rd/topic/README Before improving the docs about topics, lets move them into the topics folder.

README: move CHANGELOG to a new file

test: small cleanup in test-topic-mode.t remove the mention of "new" (this won't be new soon) and use the official config name.

test: add support for random-all topic mode The 'random' mode no longer generate a random topic for merge.

test: rename test-topicmode to test-topic-mode This is easier to read.

topicmode: add 'random' topic mode That mode will generate a random topic name when the user is about to commit an untopiced changeset.

topic: update the topic-mode hint The hint is now shorter and reference the documentation. That should provide more concise output with more details for user who seeks it.

topic: rename the 'topic-mode' help subtopic This will help making reference to it in warning.

topic: add a 'enforce-all' mode The mode abort for all commit without a topic, even merges.

topicmode: 'enforce' topic mode, no longer warn about untopiced merge merging a topic back in a branch is common case, it seems sensible to not pester the user about it.

topicmode: add new warning topicmode

topic: add documentation for the 'topic-mode' option This should help people to discover it.

test: update tests to use topic-mode enforce

topic: migrate experimental.enforce-topic to experimental.topic-mode

test: adapt to output change from 10e162bb9bf5 The changeset 10e162bb9bf5 in code extend the list of capabilities to include "phases=['heads']" this has a minor impact on test output CORE-TEST-OUTPUT-UPDATE: 10e162bb9bf5

merge with stable

stack: handle basic case of splitting with crash hg stack used to crash horribly whenever a split was encountered. This is no longer the case. If the result of the split (or there successors) produce a sensible linear result with on final head, we can just assume that head is the evolution destination.

tests: update test output with commit 4f969b9e0cf5 in core

tests: update test output with commit ecc96506c49d in core

packaging: update version to match development version This helps avoid confusion when installing from source.

packaging: merge stable back into default 6.7.0 has been released.

packaging: mark stable branch as dev bugfix version This help avoiding confusion when installing evolve from sources.

Added tag 6.7.0 for changeset 3a4f75c6619c

packaging: update debian changelog

packaging: update version number and testedwith version

packaging: mark version 6.7.0 in the source Version ready to be released.

packaging: update compatible version This has been tested with 4.3 too.

readme: prepare readme The feature that only work with 4.3+ are flagged as such.

compat-test: merge future 6.7.0 into 3.8 compat branch (merging through 3.9 compat branch)

compat-test: merge future 6.7.0 into 3.9 compat branch (merging through 4.0 compat branch)

compat-test: merge future 6.7.0 into 4.0 compat branch (merging through 4.1 compat branch)

compat-test: merge future 6.7.0 into 4.1 compat branch (mergeing through 4.2 compat branch)

compat-test: merge future 6.7.0 into 4.2 compat branch Couple feature to disable and other various test impact.

branching: merge future 6.7.0 in the stable branch We are getting ready to release a new version.

topic: fix topic message for mercurial 4.2 and below

README: mention that --age also shows the user While I was here, I fixed the a spelling mistake in previous commit.

topic: try to clarify the "branch" part in stack The idea is to clarify the meaning of "behind" with using the "target" word.

readme: mention the message update

topics: make sure user don't pass both the age option and a topic name

topics: spell out topics completely in help

topics: show the user who last touched the topic in --age This patch adds support for showing the user who last touched the topic in the age option to `hg topics`.

topics: initialize variable with default value instead of assigning later

topics: improve the function signature by accepting arguments as **opts

topic: merge with strip related fix

topic: skip topic movement message during strip During strip transaction the repository is not in a great state. It is simpler to skip the computation entirely.

topics/ui: detect and signal when an empty changeset becomes non-empty

topics/transaction: return immediately if we are in the middle of a transaction

topics/ui: signal when an operation entails voiding a topic Typical situations may include: * publish * push (to publishing server) * pull * fold

topics/ui: signal when the topics command creates a new (empty) topic

topics: signal to the end user when a topic has been forgotten Situation is: * we're updating outside an empty topic. * we've cleared topics

topic: add a --topic option to "outgoing" command By symmetry with "push" in the previous changeset.

topic: add a --topic option to "push" command This is symmetrical with --bookmark or --branch; it selects changesets in specified topic as revisions to push.

test-compat: adapt to core change in b90bd9a98c8b Blackbox just got a little more chatty.

readme: update about obslog update and documentation refresh

topic/tuto: be more precise in the top introduction about the publishing server Indeed there is a chapter with a non-publishing one.

topics/tuto: prefer rebase over merge and remove the weird merge attempt

topics/tuto: typo fix and s/multiple/two

topics/tuto: be more complete over the de-orphaning action within a topic

topics/tuto: try to be more precise on why `hg log` output is hairy

topics/tuto: attempt to have a slightly more clear wording

topics/tuto: try to be more clear when explaining previous/next

test: fix the enforce-topic configuration There have been an error while updating this patch.

topics/tuto: clarification on the scope of the tutorial Also we try to remain the reader that push -> publish.

topics/tuto: slightly more verbose explanation of what we are seeing

topics/tuto: spell out `hg topics` entirely

topics/tuto: activate the `enforce-topic` option This really help users to stick within topics.

topics/tuto: highlight the behaviour on publish + update And the fact that empty topics vanish if we update out of them.

topics/tuto: fix title underline type introduced earlier

doc: update graph with latest version of doc-graph

flake8 docs/conf.py

doc: disable generating command documentation when mercurial is not up-to-date

doc: add documentation for evolve commands By using a sphinx directive that call `hg help`.

doc: clarify undocumented features

test2rst: ignore the #if/#endif line in the output They are not useful for the rest.

doc: integrate graphviz graphs in tutorials Use the mercurial-docgraph extension (https://pypi.python.org/pypi/hg- docgraph/) in tutorials in order to have some dot graphs in the tutorials .t files. Then generate the doc as usual, the sphinx-graphviz extension (http://www .sphinx-doc.org/en/stable/ext/graphviz.html) has been added and it should handle the generation of the graphs. Please be aware that you need the dot binary installed in your system. Please refer to the extension documentation for more configuration.

doc: add a special flag for content to ignore in the rst The testfile to rest document convertion has a new way to ignore some commands.

obslog: simplify formatter keys The formatter field keys are all prefixed with `debugobshistory.'. This is annoyingly useless as they are already in the `debughistory` topic. This patch simplify these keys. For examle, on this repository `hg obslog -Tdebug -r 31cbace4c0f1` : ``` debugobshistory = [ { 'node':'31cbace4c0f1', 'shortdescription':'topics: make sure we have some restrictions on topic names', 'rev':2904, 'markers':[ ] }, { 'node':'d439a6087434', 'markers':[ { 'date':(1504176329.83902, -7200 ), 'verb':'rewritten', 'succnodes':[ '31cbace4c0f1' ], 'effect':[ 'parent' ], 'user':'Pierre-Yves David <pierre-yves.david@octobus.net>' } ] }, { 'node':'1e1f651704d4', 'markers':[ { 'date':(1504175088.811924, -7200 ), 'verb':'rewritten', 'succnodes':[ 'd439a6087434' ], 'effect':[ 'parent' ], 'user':'Pierre-Yves David <pierre-yves.david@octobus.net>' } ] }, { 'node':'eb6495cf6cb1', 'markers':[ { 'date':(1504015275.001643, -19800 ), 'verb':'rewritten', 'succnodes':[ '1e1f651704d4' ], 'effect':[ 'parent', 'content' ], 'user':'Pulkit Goyal <7895pulkit@gmail.com>' } ] }, { 'node':'761e446e0112', 'markers':[ { 'date':(1504015201.780276, -19800 ), 'verb':'rewritten', 'succnodes':[ 'eb6495cf6cb1' ], 'effect':[ 'content' ], 'user':'Pulkit Goyal <7895pulkit@gmail.com>' } ] }, { 'node':'531a626950bd', 'markers':[ { 'date':(1504015017.897054, -19800 ), 'verb':'rewritten', 'succnodes':[ '761e446e0112' ], 'effect':[ 'meta', 'parent', 'content' ], 'user':'Pulkit Goyal <7895pulkit@gmail.com>' } ] }, { 'node':'c2f9ba7329ea', 'markers':[ { 'date':(1504014136.876537, -19800 ), 'verb':'rewritten', 'succnodes':[ '531a626950bd' ], 'effect':[ 'meta' ], 'user':'Pulkit Goyal <7895pulkit@gmail.com>' } ] }, ] ``` We now able to ask `hg obslog -r 78debdfb3e4d -T '{label("log.summary", shortdescription)}\n{if(markers, markers % " {date|age} {user|person}\n")}'` ``` doc: simplify the reference to in-core features 9 days ago Pierre-Yves David 9 days ago Pierre-Yves David 9 days ago Pierre-Yves David 9 days ago Pierre-Yves David 9 days ago Philippe Pepiot 9 days ago Philippe Pepiot ```

obslog: fix `--template` with `--graph` option The `template` option was not propagated.

obslog: uniformize `_debugobshistoryrevs` and `_debugobshistorygraph` arguments `_debugobshistoryrevs` and `_debugobshistorygraph` perform quite the same action, the latter simply add graph support. Consequently, it looks better for them to have the same argument list.

obslog: fix --patch with --no-graph options The repo given to _debughistorydisplaymarker which computes the diff was filtered when graph mode is disabled.

commands: upgrade pdiff and pstatus to full commands Doing so make them appears in the documentation, improving their discoverability.

gup/gdown: properly mark these commands as deprecated They are no longer displayed in the documentation.

Backed out changeset 1b4c92621e23 This got published by mistake.

doc: integrate graphviz graphs in tutorials Use the mercurial-graphviz extension (https://bitbucket.org/octobus/mercurial_graphviz) in tutorials in order to have some dot graphs in the tutorials .t files. In order to run the tests, export the GRAPHVIZ_EXTENSION variable which points to your copy of the extension. Please be aware that pygraphviz should be installed in your environment. That should be sufficient for generating dot graphs in text format. Then generate the doc as usual, the sphinx-graphviz extension (http://www .sphinx-doc.org/en/stable/ext/graphviz.html) has been added and it should handle the generation of the graphs. Please be aware that you need the dot binary installed in your system. Please refer to the extension documentation for more configuration.

amend: lift the --interactive constraint on `--extract` The uncommit logic now supports interactive selection.

readme: mention the topic output cleanup

readme: mention the new --interactive mode for uncommit

uncommit: minor comment cleanup in the test Fix some of the sectionning and fix on comments.

uncommit: small cleanup of the interactive test setup

tests: add tests for interactively uncommitting by mentioning files

uncommit: fix the dirstate handling in `uncommit -i` This patch fixes the dirstate handling after `hg uncommit --interactive`. This patch is bit verbose about the logic and efforts are not put to plug the logic into existing logic as it's easier to understand like this. Plugging this into non-interactive logic deserves a separate patch.

uncommit: pre-indent a block in if-True The block will be moved in if-else in next patch.

uncommit: add an interactive option to uncommit This patchs adds an interactive flag to uncommit command which lets you choose hunks interactively. The implementation is as follows: 1) prompt user to select hunks to uncommit interactively 2) make a temporary commit of the hunks user selected 3) calculate the diff of temporary commit and changeset to be uncommitted 4) commit that diff which results in the changeset which should be there after uncommiting 5) create obsmarkers as required, phases and bookmarks handling 6) reroute the working directory

uncommit: pre-indent a block in if-True for the next patch

topic: provide more information when behind count cannot be computed The behind count has been confusing for various user and the associated error message is even worth. We try to clarify it to see if that helps.

topic: show the t0 even if topic is not yet touched

topics: improve the description if topic is not touched Instead of an empty stack in `hg stack` when topic does not contain any changeset, we show `not yet touched`.

topics: show working directory branch when topic is empty

topics: add tests for cases when a topic is empty

readme: mention compatibility with future 4.4

topic: update the message used with --age for empty topic This clarify things when a topic got emptied by publishing.

sharing: edit pass

user-guide: edit pass

topic: stabilise the output of --age when date ties We just needed to introduce sort to stabilize the output order.

tests: update after removing of redundant amend commit Following e8a7c1a0565a, temporary amend commits has been removed impacting all revision numbers in tests including amend operations. Update tests case to use description or hashes when possible and update revisions number when not.

topic: setup 'topic' value for working ctx The way amend work in core change in e8a7c1a0565a. The intermediate commit disappear and we can no longer rely on it to carry the topic value to amend. To fix this, we ensure the current topic value can be retrieved through the `workingctx.extra()` value. Since there is no way to carry a "missing" key information in a way that survives and "dict.update" call. We also has to introduce hacking behavior about a special empty value for topic.

tests: abstract version number for test-topic-stack.t Using explicite version number always bring trouble, this is why we have unique description that can select changesets.

evolve: use registrar.templatekeyword to register template keyword functions Now, using registrar.templatekeyword of Mercurial directly in evolve extension should be safe enough. because it has been available since Mercurial 3.8, and minimum Mercurial version for evolve extension is 3.8, too. BTW, this also fixes an issue of "hg help templates" output that template keywords "precursors" and "successors" are not displayed as same as others, because they do not have ":KEYWORD:" prefix in their docstring.

evolve: use registrar.revsetpredicate to register revset predicate functions Now, using registrar.revsetpredicate of Mercurial directly in evolve extension should be safe enough. because it has been available since Mercurial 3.8, and minimum Mercurial version for evolve extension is 3.8, too.

topic: use registrar.revsetpredicate to register revset predicate functions Now, using registrar.revsetpredicate of Mercurial directly in topic extension should be safe enough. because it has been available since Mercurial 3.8, and minimum Mercurial version for topic extension is 4.0. This patch also removes modsetup() in topic/revset.py, because it is useless. BTW, this patch fixes an issue of "hg help revsets" output that custom revset predicates are not displayed as same as others, because they are not "inline literal" in reST syntax (``NAME``).

doc: make paragraphs before example code end with "::" for reST syntax This prevents lines in an example code from being treated as a part of normal paragraph. For issue example, lines are folded into one paragraph.

topic: centralize compatibility logic between hg versions into compat module This patch can delay loading obsutil and obsolete modules until they are actually used at "hg topics" or so, if demandimport of Mercurial is enabled.

readme: mention the improvement to stack in the readme

test: issue a clarifying graph print in tests/test-stack-branch.t

stack: properly order stack when gaps existing inside it We transitively search for the next "stack" ancestors, of changeset in the stack not based on other revision of the stack. This should help having a consistent display when topic are interleaved.

stack: display both parent with displaying merge This will help understanding merge in the stack. More test involving merge are adding in the next changeset.

tests: add tests for showing stack when merge is involved This patch adds tests of showing stack when merges are involved. This will help us in changing the behaviour and realising that in later patches.

stack: move data computation on the object We gather multiple data about the stack on the object. Let us move this on the object and keep it cached there.

stack: replace 'getstack' with direct call to 'stack' The dedicated function do not add any value. We can update all the callers.

stack: introduce a rich stack object The logic around stack object become more and more complex. We great and object to gather and abstract it.

tests: add tests for `hg stack` showing surprising behavior with gaps The test will help us to analyse in next commit if the things are fixed or not.

topic: check availability of obsutil.getmarkers() for portability Before this patch, topic extension causes unintentional failure with Mercurial earlier than 4.3, because obsutil.getmarkers() has been available since Mercurial 4.3 (tests for topic on mercurial-4.* branches fail, too). This breaks "minimumhgversion = '4.0'" declaration of topic extension. This patch fixes this issue in a straightforward way for simplicity on stable branch. I'm planning to centralize such portability logic in topic extension into topic/compat.py or so on default branch for efficiency at runtime, like as evolve/compat.py.

tests: add more explicit test about empty topic from publishing

convertbookmark: advertise the new command in the readme The command is in a good enough shape now.

convertbookmark: properly convert stacked bookmarks We ignores pure descendant when looking for revision to convert. This adds support for cases were a linear stack contains multiple bookmark (or un-bookmarked descendants exists). In this case, some changeset are left orphan, but we'll consider the issue as minor for now.

convertbookmark: perform all actions at the end This will make the whole operation more deterministic and robust.

converbookmark: split target computation from actual update This will allow for further refactoring helping consistency.

convertbookmark: extract the revset into a module level constant This will make it easier to read and modify the query.

convertbookmark: properly exclude public changeset Public changeset are immutable and cannot have a topic anyway.

test: add a new root changeset to all debugconvertbookmark test case We'll make this root changeset public to check the debugconvertbookmark logic in that regards. It is added in its own changeset since it massively impact all output.

tests: import section in 'test-topic-debugcb.t' We now have two levels of titles to clarify some aspect of the tests.

test: avoid using debugdrawdag in 'test-topic-debugcb.t' The 'debugdrawdag' utility adds local tags that prevent hidden changeset to get hidden. We will do without that extension for now.

tests: add more tests for debugconvertbookmark

convertbookmark: add logic to skip revisions with multiple bookmarks When a user tries to converts a bookmark to topic which is on a changeset with more bookmarks we skip that.

topics: add a new debugconvertbookmark command to convert bookmarks to topics This new command, aliased to debugcb converts bookmarks to topics. This command either accept name of a bookmark using flag '-b' or '--all'. If a bookmark is passed using '-b', the whole stack defined by that bookmark is converted to topics. If '--all' is passed, the above thing is repeated for every bookmark in the repository. If the revset which we are using unable to decides revisions of the stack and return an expty set, in that cases we are not deleting the bookmark as we are not writing any topics of the same name as that of bookmark. Also currently if a changeset has two bookmarks, than there is buggy behaviour. So these are known lackings in the current implementation which will be fixed in upcoming patches. This also adds tests for the same.

topic: support --rev argument and properly process then as user input Revisions inputed by the users should be processed using `scmutil.revrange`. This will take alias into account and allow extensions to monitor the user inputs. As a side effect, the '_changetopics' function takes revisions as argument. make the API clearer.

topic: move a status message in the right scope The finally get runs on failure so we should not advertise rewrite topic in the case. In addition the 'rewrote' variable can be undefined in the finally.

obsfate: use effect flag information for computing a better verb

compat: make it more clear that evolve need Mercurial >= minversion The message is more clear when mercurial isn't installed at all.

doc: record all the missings and strange bit we know We know the doc is not as fresh as it could be. We make sure the reader is aware too.

directaccess: fix with tree without order 1b28525e6698 removes order from tree, changing the indexes in gethashsymbols. Fix that

compat: adapt to test output changes different access pattern in 4.4 means different results. Make evolve works with mercurial core 72b5f4d53c58

compat: adapt to rebase change in coming 4.4 Make evolve works with mercurial core 72b5f4d53c58

topics: import lock as lockmods We'll need a 'lock' variable in the next changeset. we move the module out of the way ahead of time for clarity.

topics: make sure we have some restrictions on topic names This patch makes sure we don't allow topic names with just whitespaces, and other checks which we do for a bookmark.

topic: add test showing no restrictions on topic names Currently we don't have any restrictions on topic names and each of the topic name works. We want them to not work as some of them are used internally and only integers can be rev numbers too.

index: edit pass by native english speaker

topic: reword and simplify explanation of "behind"

topic: tutorial grammar fixes

doc-front-page: link to the changeset evolution section in the document The section is unlikely to be perfect, but at least it exists.

doc-front-page: use a clearer statement about the experimental status This text comes form the Mercurial wiki.

doc-front-pagE: add a paragraph about "why the extension" Let us clarify why there is an extension in the first place.

doc-front-page: expand the paragraph about changeset evolution We clarify the part of the explanation about the changeset evolution concept.

doc-front-page: rename the "next step" section This are pointer to relevant section in the doc. It is a bit double usage with the table of content. We at least clarify the title.

doc-front-page: mention that "Changeset Evolution" is a specific concept It will get it own paragraph soon.

doc-front-page: include the index in the TOC This will help important content to stand forward.

doc-front-page: add a title to the part about the extension We'll rework this section more in depth, but I would like it to have a title first to have it show up in the table of content.

doc-front-page: add a feature summary at the beginning of the page

doc-front-page: mention the mailing list in the documentation It is an important tool to keep people up to date.

doc-front-page: move installation instruction earliero This is important for user.

doc-front-page: move introduction before the table of content This should make a friendlier landing.

doc: simplify the reference to in-core features This should do the whole thing lighter.

doc: be less dramatic about changeset immutability Quoting Phillipe: "This is not a Tolkien Novel".
