persistent-nodemap: introduce a test to highlight possible race
Weakness in the current file caching of the changelog means that a writer can
end up using an outdated docket. This might result in "committed"
persistent-nodemap data from a previous writer to be overwritten by a later
writer. This break the strong "append only" assumption of the persistent nodemap
and can result in confused reader.
The race windows are quite narrow. See the test documentation for details.
The issues is fixed in the next changeset.

Mercurial ========= Mercurial is a fast, easy to use, distributed revision control tool for software developers. Basic install:: $ make # see install targets $ make install # do a system-wide install $ hg debuginstall # sanity-check setup $ hg # see help Running without installing:: $ make local # build for inplace usage $ ./hg --version # should show the latest version See https://mercurial-scm.org/ for detailed installation instructions, platform-specific notes, and Mercurial user information. Notes for packagers =================== Mercurial ships a copy of the python-zstandard sources. This is used to provide support for zstd compression and decompression functionality. The module is not intended to be replaced by the plain python-zstandard nor is it intended to use a system zstd library. Patches can result in hard to diagnose errors and are explicitly discouraged as unsupported configuration.
