hgweb: Fix deprecation warning in Python 3.10 (issue6520) Differential Revision: https://phab.mercurial-scm.org/D10711

dirstate-tree: Remove newly-empty nodes after removing a `DirstateEntry` This is actually necessary to make `DirstateMap::has_dir` correct, since it assumes that a node without a `DirstateEntry` has at least one descedant node with a `DirstateEntry`. This bug would become apparent when a later changeset persists tree nodes on disk in the "dirstate-v2" format. Differential Revision: https://phab.mercurial-scm.org/D10706

dirstate-tree: Refactor DirstateMap::drop_file to be recursive It should behave the same as before. This will enable the next changeset to run code on the way "down" (in order to removing newly-empty nodes). Differential Revision: https://phab.mercurial-scm.org/D10705

templates: fix `revset('parents()') % ...` in amend message template I don't understand why, but putting `revset('parents()') % {desc}` in the commit message template for amend resulted in a crash because `memctx.hex()` did `hex(self.node())` and its node was None. This patch fixes that. Martin von Zweigbergk <martinvonz@google.com> Differential Revision: https://phab.mercurial-scm.org/D10707

path: teach the `hg path` command to display boolean sub-option The next changeset introduce one. Differential Revision: https://phab.mercurial-scm.org/D10450

parselist: move the function from config to stringutil We move the function in a lower level module to avoid cycle. It moves next to `parsebool` who had to migrate for the same reasons. Differential Revision: https://phab.mercurial-scm.org/D10449
