It seems, that every version in tree is incompatible with dev-python/zstandard. If you try to clone a repo, it will fail. "https://hg.prosody.im/prosody-modules/" is an example public repo. $ hg clone https://hg.prosody.im/prosody-modules/ Target directory: prosody-modules abort: compression engine zstd could not be loaded Thanks to slashbeast, the problem is 'hg' itself. If you look into 'utils/compression.py', search for line 'from .. import zstd # pytype: disable=import-error' This seems to be incompatible with dev-python/zstandard. If replaced with 'import zstandard as zstd', everything works normal. BUT: This code is even present on the lastest upstream master, so it should be checked, what to do. -> https://www.mercurial-scm.org/repo/hg/file/tip/mercurial/utils/compression.py
Upstream says: <> https://gitweb.gentoo.org/repo/gentoo.git/tree/dev-vcs/mercurial/mercurial-5.6.1.ebuild#n153 <> that's wrong. <> Correct options are: <> 1) use our bundled zstandard <> 2) omit our bundled zstandard <> other choices are incorrect and are likely to be broken (as you've observed)
Which version of dev-python/zstandard are you using? For me it works with 0.14.0-r1.
And also which Python implementation are you using? Is it PyPy?

[ebuild R ] dev-python/zstandard-0.15.1::gentoo USE="-test" PYTHON_TARGETS="python3_8 python3_9 -pypy3 (-python3_6) -python3_7" 0 KiB I am not using pypy, plain python3.
The 0.15.1 seems to no longer providing zstd.cpython-*-linux-gnu.so as module that can be loaded. However the zstandard module have compatible interface.

However the zstandard module have compatible > interface. Indeed they seem to have rename into "backend_c.cpython-*-linux-gnu.so" and move it under `zstandard` directory. I will adapt the ebuild to import zstandard as zstd (which will permit also to support cffi only interpreter like PyPY).

Great, many thanks :-)
