[issue45153] Except multiple types of exceptions with OR keyword is not working
New submission from Shlomi :
When I want to catch multiple types of exceptions naturally 'OR' keyword is
used. But it doesn't work. The interpreter doesn't show any error for the
syntax, so developer may think it would work.
Small example:
try:
myfunc()
except ConnectionResetError or ConnectionAbortedError:
print("foo")
except Exception as e:
print("bar")
When myfunc() throws 'ConnectionAbortedError' the interpreter enters "bar"
block, and not "foo" block.

[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 .

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?

[issue24958] Segfault in REPL after pressing "r" and PgUp twice (on Mageia Linux x86-64 6)
New submission from Shlomi Fish: After I run python3 (to run the REPL) and type "r" and then PgUp twice, I get a segfault.

[issue24958] Segfault in REPL after pressing "r" and PgUp twice (on Mageia Linux x86-64 6)
Shlomi Fish added the comment: I'm attaching here the reduced, minimal, inputrc. I think it's a bug in Python because it doesn't happen with any other program that uses readline (bash, perl -d, etc.) that I checked. I'll check with a vanilla readline compiled from source from the GNU site , though. -- Added file: http://bugs.python.org/file40294/_inputrc ___ Python tracker <http://bugs.python.org/issue24958> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue24958] Segfault in REPL after pressing "r" and PgUp twice (on Mageia Linux x86-64 6)
Shlomi Fish added the comment: Hi all! Thanks for the investigation. I have now built readline-6.3 from source using: ./configure --prefix="$HOME/apps/readline-TO_DEL" --with-curses=yes --enable-multibyte and installed it. Then I built python 3.4.3 from source against it by setting LIBRARY_PATH/CPATH/etc. and by this patch to setup.py: if True: # if cross_compiling: self.add_gcc_paths() After I built it and ran it, it still segfaults after I type "r" and press PgUp twice.
