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

softstrip: move _bookmarkmovements() call to where it's needed The call to `_bookmarkmovements()` is unrelated to the backup, so let's move it after. Differential Revision: https://phab.mercurial-scm.org/D9984

tests: fix differing output between py2 and py3 db9e33beb0fb broke the tests because of the difference in bytestring repr between py2 and py3. Rather than backout that change for so little, I figured I'd fix it myself. Hopefully Python 2 supports gets dropped very soon. Differential Revision: https://phab.mercurial-scm.org/D9987

build: fake PEP440 versions If the current version is not exactly a tag, use a local version specifier to fix it up. PEP 440 uses the "+" separator and only allows alphanumeric and dot, so use dot for further separations. Old devel build: 5.7+155-a163cc36d06b New devel build: 5.7+hg155.a163cc36d06b Differential Revision: https://phab.mercurial-scm.org/D9955

tests: add a comment in a test that will hopefully save someone some time I spent at least an hour, probably closer to 1.5, trying to figure out what this was complaining about. Hopefully anyone else in my position will see this note and not waste the time. Differential Revision: https://phab.mercurial-scm.org/D9953

changegroup: don't convert revisions to node for duplicate handling The only consumer can handle revision lists fine. Avoid materializing a range if there are no duplicates as optimization. Differential Revision: https://phab.mercurial-scm.org/D9884
