Hello developers,
I have been writing a patch series[1] to integrate a lookup table extension
to .bitmap file. I reformatted the test code so that I can run the same
tests for the lookup table extension. But this is causing a failure in a midx
bitmap related test case[2]. It is not related to my code because this
can be produced with out my changes.
If you see the test file[3] (with my changes) and also observe the test
results[4], you'll notice that the said test case is always failing on the
second `test_midx_bitmap_cases` call under sha-256 only. This is racy in nature.
I.e. it might pass after executing the test 2 or 3 times.
I have been trying to solve the issue for one or two week but as I am not
very clear about the internal working of multi-pack-index or repacking, I
am still not able to solve the issue. Besides, my semester exam is starting
from 18 Aug. So I have to give a significant amount of time to studies.
So, it will be very helpful if anyone help me to find out the solution.
You can know more from this thread[5].
Thanks :)
