[issue21049] Flood of “ImportWarning: sys.meta_path is empty” after exception with socket subclass
New submission from Martin Panter: With the code included below, and warnings enabled, I see a flood of unexpected ImportWarnings as the interpreter exits. The issue is seen with Python 3.4.0, but apparently not with 3.3.5. The issue originally happened with code using the Py Socks library https://github.com/Anorov/PySocks, which I interrupted because the connect() call was hanging.

[issue20904] HAVE_PY_SET_53BIT_PRECISION for m68k
Mark Dickinson added the comment: I don't think fixing bugs on a specific architecture counts as a new feature. It's not really a bugfix, though. Python 3.4 *should* (I'm not in a position to check, but Andreas may be) be behaving as designed on m68k: the configure script will correctly determine that there's a potential issue with double rounding, and since it doesn't currently know of any way to control the FPU precision setting on m68k, it'll set the environment variables up so that the legacy floating-point repr code is used. The built Python should function as normal, expect that sys.float_repr_style will be 'legacy' instead of 'short', and we won't get the (primarily cosmetic) benefits of the short float repr. This patch then changes the part where Python doesn't know how to change the precision, allowing it to use David Gay's short float repr code instead of the legacy code. So I see it as an enhancement rather than a bugfix. And this would actually be a somewhat significant behaviour change: on m68k with Python 3.4.0, we'd see: 1.1 1.1001 and (if this patch went into the 3.4 branch), on Python 3.4.1 we'd see instead: 1.1 1.1 The behaviour of string formatting and the round function would also change in edge cases. There's an argument that the number of users affected by this change is likely to be tiny, so changing this in 3.4.1 is unlikely to break people's code. But the tininess of the userbase is equally the basis of an argument that the change isn't at all urgent, and those affected can wait for Python 3.5 or patch their copy of Python; I don't see a really good reason to break the policy about new features on bugfix branches for this particular issue. Given all that, I don't think it would be appropriate to include the change in Python 3.4.1. I'd personally like to see it go into Python 3.5, but that's dependent on the outcome of the we don't accept patches for unsupported platforms discussion (which is orthogonal to the 'is this an enhancement or a bugfix' discussion). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20904 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Andreas Schwab added the comment: I didn't bother since this one fixes it for me (and also other python modules). IMHO it's the correct way to fix it, since no other architecture except these two will have the problem. Since you say the non-short-float code is legacy this will make it also possible to drop it.

[issue20904] HAVE_PY_SET_53BIT_PRECISION for m68k
Mark Dickinson added the comment: I guess they will get fixed over time, or declared unsupported. :-) Yes, probably. I'd fully support a move to get rid of that legacy code in Python 3.5. That would definitely require a python-dev discussion, though (and possibly a PEP): up until now the policy has been that Python just works with whatever floating-point format the platform's C double provides, with no assumptions about IEEE 754, etc. I think we've mostly fixed the issues on mainstream platforms (e.g., Sun and Intel compilers on x86). Probably the most troublesome remaining case is ARM / OABI, where I think we still don't have code to deal with the mixed-endian (more strictly, little-endian swapped words) format for C doubles. There are some online environments (Python via JavaScript, etc.) that also currently use the legacy code. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20904 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Some of the functions, like mode() and the median functions, don't have equations.

If you print out what module is being imported at the time of the warning its 'io' and it's only coming up after the script has exited (you will notice the warnings come up after the traceback is printed). My guess is some cleanup code that gets called a lot is trying to import io after shutdown cleanup has blasted sys.meta_path. I should also mention that if you raise an exception instead of print the warning nothing shows up, which is another indicator that this is a shutdown-related issue since that could quite easily consume the exception.

Anyway, what looks suspicious to me is this line that gets imported by pywintypes: # extension module loaded from 'C:\\Python34\\lib\\site-packages\\win32\\_win32sysloader.pyd' That module's name suggests it might be critical. I also wonder what is going on with your sys.path as pywintypes is coming from site-packages\win32\lib\pywintypes.py while win32api is coming from site-packages\\win32\\win32api.pyd (notice how pywintypes is in some lib subidrectory and win32api is not).

Antoine Pitrou added the comment: For a more detailed analysis: - the warning gets printed very late because the socket is caught in a reference cycle (self.attr = self), which itself is tied to the exception traceback - when the socket is collected, it tries to print a ResourceWarning because it hasn't been closed explicitly (just add self.close() in the constructor to make it disappear) - when trying to print the ResourceWarning, it probably wants to import linecache or something, and that breaks The only remaining mystery is why there are 200 lines and not just one :-) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21049 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue21049] Flood of “ImportWarning: sys.meta_path is empty” after exception with socket subclass
Brett Cannon added the comment: So the import warnings were added for sys.meta_path and sys.path_hooks because prior to Python 3.3 you could empty out those values and import would continue to work, but with importlib that stopped being the case. My thinking was that it would be easier to debug if you got that warning instead of your imports entirely failing and wondering what was going on. But perhaps sys.path_hooks and sys.meta_path are known well enough at this point that the warnings are superfluous. I'll open a separate bug to track that discussion. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21049 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue21052] Consider dropping ImportWarning for empty sys.path_hooks and sys.meta_path
New submission from Brett Cannon: Issue #21049 managed to trigger a huge output of ImportWarning: sys.meta_path is empty because it managed to trigger an import during interpreter shutdown. The ImportWarning for sys.path_hooks and sys.meta_path were originally added because before importlib took over import it was totally legal to blank out sys.path_hooks and sys.meta_path and have import continue to work. But hopefully by the time Python 3.5 comes out there will be enough knowledge out there to not blindly empty them, making the warning superfluous as well as an annoyance when things go wrong in other respects. -- components: Interpreter Core messages: 214702 nosy: brett.cannon, eric.snow, ncoghlan priority: normal severity: normal stage: needs patch status: open title: Consider dropping ImportWarning for empty sys.path_hooks and sys.meta_path type: behavior ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21052 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue20992] reading individual bytes of multiple binary files using the Python module fileinput
Josh Rosenberg added the comment: fileinput's semantics are heavily tied to lines, not bytes. And processing binary files byte by byte is rather inefficient; can you explain why this feature would be of general utility such that it would be worth including it in the standard library? It's not hard to just get a byte at a time using existing parts: def bytefileinput(): return (bytes((b,)) for line in fileinput.input() for b in line) There are ways to do similar things without using fileinput at all. But it really depends on your use case. Giving fileinput a read() method isn't a bad idea assuming some reasonable behavior is defined for the various line oriented methods, but making it iterate binary mode input byte by byte would be a breaking change of limited utility in my view. -- nosy: +josh.rosenberg ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20992 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Andreas Schwab added the comment: We are actually talking about Linux here, I assume everyone knows what that is :-) Also the patch is 2 files changed, 32+ (if you ignore the autoconf generated files), which is quite a bit smaller than the final version of the atheos patch (which is 19 files changed, 544+, 15-, also generated files ignored). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20904 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue20210] Provide configure options to enable/disable Python modules and extensions
Éric Araujo added the comment: The main issue with the proposed changes is that it redefines what “the Python standard library” is. Right now, users can mostly expect modules listed in the official Python docs to be available in their installation, regardless of how they got their Python. I say “mostly” because a distributor may exclude tests from a binay package, split some extensions modules like _tkinter and _lzma in other packages, etc. A big source of pain in the past was distributors splitting distutils, but I think they all stopped. (A related issue is that some distributors backport many bug fixes and sometimes features, which is a pain when you think you’ve run your tests with “Python X.Y.Z” and it was actually “X.Y.Z+some-patches”.) -- nosy: +eric.araujo ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20210 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Thomas Petazzoni added the comment: But this expectation is not true: if dependencies are not available, Python silently disables the build of certain modules.

[issue20992] reading individual bytes of multiple binary files using the Python module fileinput
Tommy Carstensen added the comment: I read the fileinput code and realized how heavily tied it is to line input. Will reading individual bytes as suggested not be very memory intensive, if each line is billions of characters? def bytefileinput(): return (bytes((b,)) for line in fileinput.input() for b in line) I posted my workaround on stackoverflow (see link earlier in tread), which does not make use of the fileinput module at all. After having read through the fileinput code I agree that the module should only support reading lines and this enhancement request should be closed. -- resolution: - rejected status: open - closed ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20992 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue20904] HAVE_PY_SET_53BIT_PRECISION for m68k
Stefan Krah added the comment: Benjamin Peterson rep...@bugs.python.org wrote: I don't want to scare away contributors. I think this is a very important point. Initially I was skeptical about m68k, too (msg182388), but I've completely changed my opinion due to the nature of the patches. So far, the m68k issues were about C-standard compliance and timing assumptions in tests. This one is a small patch that won't affect anything else. My experience with exotic Linux ports (Debian SPARC, etc.) is that the Python test suite works rather well out of the box. So I don't expect to have a flood of posixmodule.c patches or similar (perhaps Andreas can confirm that). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20904 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue20992] reading individual bytes of multiple binary files using the Python module fileinput
Josh Rosenberg added the comment: On memory: Yeah, it could be if the file didn't include any newline characters. Same problem could apply if a text input file relied on word wrap in an editor and included very few or no newlines itself. There are non-fileinput ways of doing this, like I said; if you want consistent performance, you'd probably use one of them. For example, using the two arg form of iter: from functools import partial def bytefileinput(files): for file in files: with open(filename, rb) as f: yield from iter(partial(f.read, 1), b'') Still kind of slow, but predictable on memory usage and not to complex. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20992 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue21044] tarfile does not handle file .name being an int
Antoine Pietri added the comment: Well, this behavior seems pretty inconsistent to me, it means that every library has to check if the name attribute is actually a string (which would correspond to a path) or an int (that would mean a fd), and I think a fd attribute would seem more consistent. But as I don't think we could change this behavior that easily (it means breaking retrocompatibility after all...), we must at least make tarlib deal with that. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21044 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
