upgrade: speed up when we have only nodemap to downgrade Similar to what we do on upgrade, if we have only persistent-nodemap to downgrade we will just delete the nodemap files and update repository requirements instead of processing all the revlogs. After downgrade, we are left with unrequired docket and transaction files which seems fine but can work on deleting them if someone feels we should.

upgrade: write nodemap for manifests too In 98e39f04d60e I assumed that writing nodemap for manifests was not desirable and stopped writing it during upgrade. However in recent discussion with Pierre-Yves, I learnt that that's not true. Differential Revision: https://phab.mercurial-scm.org/D9991

windows: fix parsing of version number to match format from D9955 Differential Revision: https://phab.mercurial-scm.org/D10061

build: make version from .hg_archival.txt consistent with that from .hg/ D9955 changed the version format to replace "-" by "." and to add "hg" before the number representing the distance from the latest tag. However, it missed the "hg" string and added an extra "." to the version string we produce when there's a `.hg_archival.txt`. This patch makes it consistent.

re2: byteify some regex used to get check re2 availability Changeset 687b865b95ad failed to properly byteify this because it was a raw string. This went undetected so far because re2 does not seems to be widely tested. Differential Revision: https://phab.mercurial-scm.org/D10064

packaging: add Provides: python3-mercurial and Homepage to debian package There are other packages that depend on python3-mercurial, like debian's mercurial-git, so we should mark ourselves as providing it. I compared the control file we generate to the one that the debian maintainers generate, and noticed several differences: - the Homepage bit. I included this, because why not - a more robust Suggests list that includes a graphical merge tool - a more robust Breaks list - debian's Recommends openssh-client, we only Recommends ca-certificates - a split into `mercurial` and `mercurial-common` (and possibly others?) - a slightly different description Differential Revision: https://phab.mercurial-scm.org/D9983

bundle2: pass the operation source down to the changegroup This is currently not used by anything in core (and redundant with the url), the real source information is much more useful. This is going to be used in sidedata exchange patches coming soon. Differential Revision: https://phab.mercurial-scm.org/D9986

gendoc: use an empty comment so aliases are separated from previous elements For commands like `hg bookmarks`, where there's no `[+] marked option can be specified multiple times`, this causes the final option in the option list to not be the parent of the aliases definition. The aliases section is thus marked as a blockquote like on commands that do have text separating the option list and the aliases definition.

gendoc: add support for loading extensions from config settings We manage our installation and ship some extensions, enabled by default for our users, that are in hgext3rd or other directories not scanned by this tool by default. We want to generate docs during the build process, and having those docs include the extensions that users don't have to manually enable is desirable. This is *not* desirable for the normal build process, however, and should never be enabled by default. Differential Revision: https://phab.mercurial-scm.org/D9989

gendoc: support defaults on customopts a bit better Without this, a customopt will very likely render like this: ``` -foo does foo (default: <hgext.myextension.MyOpt object at 0x7f31...>) ``` I copied this logic from how this is handled in mercurial/help.py.

softstrip: fix a reference to an undefined variable `backupfile` wasn't defined if no backup was requested. Let's set it to `None` by default, which matches what regular `repair.strip()` does. Differential Revision: https://phab.mercurial-scm.org/D9985
