Different hash (length) in generated name

Wheels are built in the same environment, periodically some of the wheels have a different hash, differing in length by one digit.

package_name-3.7.2.dev52+g84cda2814-cp38-cp38-manylinux_2_17_x86_64.manylinux2014_x86_64.whl
package_name-3.7.2.dev52+g84cda281-cp39-cp39-manylinux_2_17_x86_64.manylinux2014_x86_64.whl
package_name-3.7.2.dev52+g84cda281-cp310-cp310-manylinux_2_17_x86_64.manylinux2014_x86_64.whl

g84cda281   [3.9, 3.10]
g84cda2814  [3.8]

version: latest

What git versions are the different builders using

It may be necessary to as always use the long describe

[senysenyseny16]

All three wheels are built in the same image with the same version of Git:

❯ docker run -it --rm quay.io/pypa/manylinux2014_x86_64
[root@b9d0ea36c864 /]# git --version
git version 2.45.2

From build to build, the incorrect names change for different versions of Python.

[RonnyPfannschmidt]

Thanks for the details, it seems like we hit a non-deterministic case in git and need to ensure a consistent minimum length

[shenxianpeng]

I tried to reproduce it on Python 3.8, 3.9, and 3.10 using this image quay.io/pypa/manylinux2014_x86_64, but it didn't reproduce. Did I miss something?

hi @shenxianpeng

I tried to look into this a little deeper and discovered that a different name is generated by unique runner from the entire set of runners in our CI. What can I do to help reproduce the problem?

I believe the safest way is to go for full nodes anytime
