stream-clone: add a v3 version of the protocol This new version is less rigid regarding the extract number of files and number of bytes to be actually transfered, it also lays the groundwork for other improvements. The format stays experimental, but this is an interesting base to build upon.

stream-clone: fix the help for an argument of perf::stream-locked-section The help for `--stream-version` had a typo and missed a value.

infinitepush: aggressively deprecated infinite push We add a large warning and an explicit abort. Both can be disable through config, but neither are explicitly documented. If any user exists I really want them to get in touch with the community.

clone-bundle: double check that inline clone bundle does not break local case Since there is a large NotImplementedError in the code, I prefer we have a double check here.

clone-bundle: drop the now unused `inlineclonebundles` capabilities We no longer us the capabilities as a side way to passe argument to the `clonebundle commands`

clonebundles: introduce a new write protocol command The old wire command does not take argument so we need a new command. We make that new command take argument to prepare it for the future (like narrow support).

clone-bundles: reorder some test section and add titles This make things clearer around the inline clone bundle tests.

clone-bundle: rename the methods and wireprotole command The current naming is very clone centric, since then, the url scheme was moved to a more generic wording to make room for other use-cases (e.g. pull bundles). We apply the same logic to the internal API and, very important prior to the release, to the wire protocol command.

delta-find: remove dead code intended to deal with forced delta reuse Since the case was dealt with sooner (see XXX), we no longer need to deal with it in this part of the code.

library: incorporate demandimport into runpy invocation

library: enable runpy invocation on mercurial package

match: add `filepath:` pattern to match an exact filepath relative to the root It's useful in certain automated workflows to make sure we recurse in directories whose name conflicts with files in other revisions. In addition it makes it possible to avoid building a potentially costly regex, improving performance when the set of files to match explicitly is large. The benchmark below are run in the following configuration : # data-env-vars.name = mozilla-central-2018-08-01-zstd-sparse-revlog # benchmark.name = files # benchmark.variants.rev = tip # benchmark.variants.files = all-list-filepath-sorted # bin-env-vars.hg.flavor = no-rust It also includes timings using the re2 engine (through the `google-re2` module) to show how much can be saved by just using a better regexp engine. Pattern time (seconds) time using re2 ----------------------------------------------------------- just "." 0.4 0.4 list of "filepath:…" 1.3 1.3 list of "path:…" 25.7 3.9 list of patterns 29.7 10.4 As you can see, Without re2, using "filepath:" instead of "path:" is a huge win. With re2, it is still about three times faster to not have to build the regex.

path: use the next `display` argument to deal with boolean We have a generic mechanism that we can now use for the special case now.

path: display proper user facing value for pulled-delta-reuse-policy The integer was not what the user expect nor what could be provided as a config value.

paths: add an argument to format the suboption display We will use it in the next function to the delta policy display. It could also be use to deal with the other special case in the command code, but that is unnecessary churn for stable so that part will go on default.

ui: fix crash in `hg paths` when pulled-delta-reuse-policy is in use The crash is a result of [value] being an int, but being used as a bytestring.
