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.

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.

tests: add a test for newline in obsnote

obsnote: don't add '' to note while showing it in obslog

obsnote: add an entry in CHANGELOG about it

amend: add support for storing a note in obsmarker

uncommit: add support for storing a note in obsmarker

fold: add support for storing a note in obsmarker

metaedit: add support for storing a note in obsmarker

prune: add support for storing a note in obsmarker

split: add support for storing a note in obsmarker

touch: add support for storing a note in obsmarker

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
