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.

obslog: add initial support for showing note in obslog This add a very basic and initial support for showing the note stored in the obsmarker in obslog to test the upcoming changes which adds support. 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

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

topic: introduce a minimal extensions to enable topic on the server This small extensions simply expose topic in the branch. This should help getting minimal support for topic from various hosting solution (eg: bitbucket maybe ?) See extensions help for details.

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.
