After I build Python-3.3.2 from the .tar.xz using the following script (on Mageia Linux Cauldron x86-64):

<<<
#!/bin/bash
./configure --prefix="$HOME/apps/python3" --with-threads \
                --enable-ipv6 --with-dbmliborder=gdbm \
                --with-system-expat \
                --with-system-ffi \
                --enable-shared \
                --with-valgrind
shlomif@telaviv1:~/Download/unpack/prog/python/Python-3.3.2$ 
>>>

then I get this test failure in the «test_no_optimize_flag»:

Please look into fixing it.

This looks related to issue 14443, which was supposed to be fixed in 3.3.0.  Can you do some of the same debugging that was done in that issue and see if it reveals any more about the problem?

Also, I notice from that issue that Antoine was (is?) running Mageia, so I'm adding him to nosy in case he wants to try to reproduce it.

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?

I don't really use Mageia anymore, that said:

> I should note that after I do «unset PYTHONDONTWRITEBYTECODE» [snip]

Yep, this is a long-lasting Mageia issue. See:
https://qa.mandriva.com/show_bug.cgi?id=50484
https://bugs.mageia.org/show_bug.cgi?id=3348

You could try arguing with the maintainer (Michael Scherer) but he seems both stubborn and slightly clueless about anything Python-related, unfortunately.

> all tests pass except for test_ftp.py, which gives me this

You are not the only one getting the test_ftp failure. I guess Giampaolo didn't fix it well enough.

> However, I don't see the bdist_rpm anywhere in the output

Individual test cases are only listed on failure, or when verbose mode is specified. So, if it doesn't appear in the output, it passed.

Benjamin fixed the ftp error message, one commit after the 3.3.2 tag.  Not sure if that is enough to make the test pass, though.

So, it sounds like 18142 should be closed as "works for me"?  That is, the remaining test failures are do to the poor system configuration in Mageia?

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?)

Given that we introduced the flag to support read-only file systems, I think one can argue that the test suite should support running on one.  However, the right thing to do would be to set up a buildbot where that was true so that it doesn't get re-broken in the future.  That might be a tad tricky to set up, I'm not sure.

Is this still a problem with later versions of Python on this platform?

Here is the new output of the "make test" with Python-3.4.1 :

You may wish to install a Mageia Linux x86-64 Cauldron Virtual Machine instead of depending of waiting for me to do all that. See:
