Investigate build issue involving cython and thriftpy in container build

[danielballan]

Cython recently release 3.0.0. In the container build GHA, I have pinned cython to <3 to work around the error below. Perhaps upstream will fix; we should try un-pinning soon.

So sorry for the noise---meant to post this against my own repo! :man_facepalming: This may or may not be a thriftpy issue.

[uonxhou]

@danielballan i have the same issue.

This is fixed by #220 .

Thriftpy2 is released by cython precompiled, so users should not got the issue. Do you install thriftpy2 from source?

[danielballan]

Yes, I would have expected to get a wheel but evidently that's not what pip saw when this ran: https://github.com/bluesky/tiled/actions/runs/5598579624/job/15165018609#step:4:746

I mean "from souce" is from the git, not the tar.gz from pypi. But I got what happened in the container.

Seems you have older version of pip / setuptools installed in the container, the older version of pip / setuptools do not use a isolated build environment. And this combination triggered cython to re-compile the .pyx to .c files.

You can upgrade pip / setuptools to get a workaround, before thriftpy2 releases a new version.

[danielballan]

Ah, that makes sense, thank you. Upgrading to latest pip and setuptools in the container is probably wise in any case.
