0.6.1: pytest is failing

[kloczek]

I'm trying to package your module as an rpm package. So I'm using the typical PEP517 based build, install and test cycle used on building packages from non-root account.

• python3 -sBm build -w --no-isolation
• because I'm calling build with --no-isolation I'm using during all processes only locally installed modules
• install .whl file in </install/prefix>
• run pytest with PYTHONPATH pointing to sitearch and sitelib inside </install/prefix>

Here is pytest output:

+ PYTHONPATH=/home/tkloczko/rpmbuild/BUILDROOT/python-snappy-0.6.1-2.fc35.x86_64/usr/lib64/python3.8/site-packages:/home/tkloczko/rpmbuild/BUILDROOT/python-snappy-0.6.1-2.fc35.x86_64/usr/lib/python3.8/site-packages

_cffi is probably to do with missing snappy system binaries

[kloczek]

_cffi is probably to do with missing snappy system binaries

In build env there is no snappy installed because I'm building it 😄
As you see snappy._snappy_cffi was not build.
Question remains .. why? 🤔

[kloczek]

Gentle ping .. any though/updates?
Did you try to reproduce this effect using procedure which I've provided? 🤔

[martindurant]

In version 0.7.0, we no longer build ... anything. You should have an easier time installing and running snappy.

[kloczek]

I did't know anbout new version because I've not received email notification about that (this is why I've created RFE about start use gh releases 😋 )

I found that 0.7.0 has some new build dependencies like use some crc modules.
May I ask why has been chosen some external crc module? 🤔
Python provides et least two standard modules (as DSOs) which provides calculate some checksums.
Are you sure that cramjam and crc32c are really needed on build module stage? 🤔

Yep just tested below patch

Please let me know if you want that patch as PR.

Hmmm .. cramjam is written in rust so DSO will be probably +30 times bigger that libarchive 😞
Why no add snapper compression to libarchive and use libarchive module? 🤔

[kloczek]

If compression needs to be fastest-as-possible all that will be wasted in case of use rust (only because higher CPU cache misses/hits ratio). 🤔

You are most welcome to propose changes to libarchive if you want, or indeed to do benchmarking.
