New Experimental Features

Bug Fixes

• shelve: demonstrate that the state is different across platforms (issue6735)
• shelve: in test for trailing whitespace, strip commit (issue6735)
• shelve: remove strip and rely on prior state (issue6735)
• tests: fix http-bad-server expected errors for python 3.10 (issue6643)

• status: let --no-copies override ui.statuscopies

• releasenotes: use re.MULTILINE mode when checking admonitions
• rhg: fallback to slow path on invalid patterns in hgignore
• Fix a bunch of leftover str/bytes issues from Python 3 migration

• keepalive: ensure close_all() actually closes all cached connections

• lfs: fix blob corruption when tranferring with workers on posix
• lfs: avoid closing connections when the worker doesn't fork
• dirstate-v2: update constant that wasn't kept in sync
• dirstate-v2: fix edge case where entries aren't sorted
• upgrade: no longer keep all revlogs in memory at any point
• rust-status: save new dircache even if just invalidated
• dirstate-v2: hash the source of the ignore patterns as well
• rhg: fallback when encountering ellipsis revisions
• shelve: handle empty parents and nodestoremove in shelvedstate (issue6748)
• profile: prevent a crash when line number is unknown
• tags-fnode-cache: do not repeatedly open the filelog in a loop
• tags-fnode-cache: skip building a changectx in getfnode

• rust: create wrapper struct to reduce regex contention issues

Backwards Compatibility Changes

• chg worker processes will now correctly load per-repository configuration

  • when given a both a relative --repository path and an alternate working directory via --cwd. A side-effect of this change is that these workers will now return an error if hg cannot find the current working directory, even when a different directory is specified via --cwd.

• phase: rename the requirement for internal-phase from internal-phase to use-internal-phase (see 74fb1842f8b962cf03d7cd5b841dbcf2ae065587)
