CI: Collection of flukes #816

Open amotl opened 1 year ago

amotl commented 1 year ago

Hi there,

within this issue, we are collecting some observations of flaky behavior on CI. It is meant to get the big picture, so that we can improve the robustness of the test suite gradually, by identifying the bad spots. To be able to do that, it is important to diligently record all observations here.

Most of the errors will be about concurrent file access going south, where specific tests are not appropriately marked with cflake, and the parallel testing based on pytest-xdist will hit concurrency issues.

With kind regards, Andreas.

It looks like DWD DMO is flaky with ValueError: month must be in 1..12? Can we do something about it so it doesn't fail Dependabot so hard?

It looks like it happened yesterday around that time:

You submitted a fix with f42b6d61784e18 already? Thanks!

Exactly! I should probably also add a test for that! .... DWD DMO file names are currently only containing month and day, which is pretty ugly to handle, especially around new year change.
