[issue41487] Builtin bigint modulo operation can be made faster when the base is divisible by a large power of 2 (i.e: has many trailing 0 digits in binary)
New submission from Shlomi Fish :
As the pure-Python code below demonstrates, when called as `python3 test.py
jitshift` it is much faster than when called as `python3 test.py builtinops`
(which takes many seconds/minutes past the 24th iteration). I am using fedora
32 x86-64 on a Cannon lake intel core i5 NUC. Tested with latest cpython3 git
master and with /usr/bin/pypy3
The improvement was done in pure-python / userland and may be improved upon
further given these or others: https://gmplib.org/ and
https://github.com/ridiculousfish/libdivide .

[issue18188] ERROR: test_no_optimize_flag on Mageia Linux Cauldron x86-64 with certain configure flags
Shlomi Fish added the comment: I see regarding test_ftp.py and the verbosity of the tests and the absence of bdist_rpm in the output - however, shouldn't the test suite handle the presence of the PYTHONDONTWRITEBYTECODE=1 flag better? (E.g: refuse to run the tests to begin with (with an error), or not run the failing tests, or unset the flag before running the test suite, or whatever?) -- ___ Python tracker <http://bugs.python.org/issue18188> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Shlomi Fish added the comment:
Hi,
I don't understand the issue in questioned - it's too wordy and unclear. I
don't know how to do the debugging in question - please guide me. I should note
that after I do «unset PYTHONDONTWRITEBYTECODE» then all tests pass except for
test_ftp.py, which gives me this. However, I don't see the bdist_rpm anywhere
in the output. Was it skipped? If so, how, where and why?
