Terry J. Reedy added the comment: It would be disconcerting if you went to this page looking for a builtin [and had trouble finding it] I agree with this premise. Since Idle, and I presume other IDEs, color code apply, coerce, intern, and buffer as builtins indistinguishably from all the others, these 4 should somehow be easy to find in or just below the rest.

[issue21342] multiprocessing RLock and Lock raise incorrect exceptions when releasing an unlocked lock.
Davin Potts added the comment: The discussion in issue23484 is leading to a recommendation that the docs be changed to reflect the actual behavior of multiprocessing's Lock and its close relatives. As far back as 2.6.9, calling release() on an unlocked threading.Lock triggered a thread.error Exception whereas doing the same on multiprocessing.Lock triggered a ValueError. This discrepancy in the behavior of Lock between modules turns out to not be a recent development. If issue23484 moves forward with changing the documentation to reflect reality, this issue would be addressed as well. -- dependencies: +SemLock acquire() keyword arg 'blocking' is invalid nosy: +davin ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21342 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Edward D'Souza added the comment: I think putting them in a separate table is good, but I think it makes more sense to appear right below the existing table at the top of the page. For better or worse, these non-essential functions are still builtins in Python 2. It would be disconcerting if you went to this page looking for a builtin (eg. coerce) and couldn't find it at the top of the page with the other builtins.

[issue23567] os.stat() tuple access vs named attribute access int vs float
Gregory P. Smith added the comment: I missed that because i was looking for it to be called out under 2.7 os.stat() docs rather than under 2.7's os.stat_float_times() which is a method nobody is likely to read the documentation for as floats have been the default since 2.5. The 2.7 docs are much less organized around this than the 3.x. Adding that note in the same paragraph on 2.7's os.stat() docs would be sufficient. For backward compatibility, the return value of stat() is also accessible as a tuple of at least 10 integers implies it, but doesn't explicitly call out the integer [ST_XXX] vs float .st_xxx difference as adding that sentence does. -- versions: -Python 3.4, Python 3.5 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23567 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue23567] os.stat() tuple access vs named attribute access int vs float
New submission from Gregory P. Smith:
Python 2.7.6 (default, Mar 22 2014, 22:59:56)
import os, stat
os.stat('/')
posix.stat_result(st_mode=16877, st_ino=2, st_dev=64513L, st_nlink=29,
st_uid=0, st_gid=0, st_size=4096, st_atime=1425341751, st_mtime=1424824650,
st_ctime=1424824650)
x =os.stat('/')
x.st_mtime
1424824650.653934
x[stat.ST_MTIME]
1424824650
os.stat_result
type 'posix.stat_result'
I have also confirmed the same behavior in 3.4.2.
This may be intentional. Tuple [stat.ST_XXX] access to the stat return value
is the old legacy way to access these prior to Python 2.2 when the stat_result
object was introduced. At that point they were likely all ints.
The os.stat_float_times() API exists to change the behavior of stat_result
objects to return ints instead of floats by default, but the behavior of the
tuple indexed values is always ints.
We need to explicitly document this behavior difference. Changing the legacy
tuple indexing behavior to return a float would likely break code.
Why file this? We just ran into a bug due to code comparing a [stat.ST_MTIME]
value to a stored stat_result.st_mtime thus continually reporting a difference
due to the precision difference between the two but the numeric comparison
doing its job regardless.

[issue23285] PEP 475 - EINTR handling
STINNER Victor added the comment: Note: I found the bug while working on a patch for #22181. My test is this shell script: $ while true; do ./python -c 'import os, signal; signal.setitimer(signal.ITIMER_REAL, 0.001, 0.0001); signal.signal(signal.SIGALRM, lambda *args: print(., end=)); print(urandom); x=os.urandom(5000); print(ok); signal.alarm(0)'; if [ $? -ne 142 -a $? -ne 0 ]; then break; fi done The test calls print() in a signal handler which can likely create a reentrant call, which is forbidden. But Python handles this case, it's fine. After removing all debug prints and reverting the fix on fileio.c, the test doesn't crash with the assertion error anymore.

[issue23550] Add to unicodedata a function to query the Quick_Check property for a character
Hammerite added the comment: Here is an initial attempt at a patch that implements the new function. Notes on this patch: - The function as implemented here returns a string: Yes, No, or Maybe. In light of the fact that Python now has enums, it is probably more appropriate that unicodedata contain an enum (QuickCheckValue, say) that has Yes, No and Maybe as values, and that the function return values from the enum. However, I do not know how to implement this in C and I do not know where I might look for an example of where something like this is done (in C) already in the CPython codebase, so I have not done that. - My example code in the initial message on this issue was in error, as it assumed that the new function would return a Boolean value. In fact, there are three possible return values (Yes, No and Maybe), and corrected code would test the return value for equality with a string (as I have implemented the function) or for equality or identity with an enum value. - When I first generated a patch, it was very long and consisted mostly of changes to three generated header files; these changes accounted for a total of about 60,000 lines' worth of patch file and appeared to be almost entirely spurious. Although one or more of these header files will genuinely be generated differently on account of my changes (a new string array _PyUnicode_QuickCheckNames is now present, along the same lines as the pre-existing 'Names' arrays), I have omitted them from the diff for being extremely bulky and for being generated code in any case. -- keywords: +patch Added file: http://bugs.python.org/file38308/quick_check_x.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23550 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

This still doesn’t explain Serhiy’s observation that sometimes no exception is raised at all, https://bugs.python.org/issue21619#msg236949.

[issue23560] Group the docs of similar methods in stdtypes.rst
New submission from Ezio Melotti:
The Doc/library/stdtypes.rst page describes in detail the built-in types and
their methods. As suggested in #21777 (see the comments on Rietveld), it might
be a good idea to group the documentation of some similar methods, such as
{r|l|}just, {r|l|}strip, {r|}partition, {r|}index, and {r|}find.
This will remove some duplication, make the page shorter and easier to
navigate, and make the methods easier to discover. Adding tables containing
the methods for each types has also been proposed.

Don't break backward compatibility. It's not like this was reported as a bug
that caused a problem for real world code, it is about theoretical consistency.
The risk of breaking someone code is much higher than the benefit of any such
consistency, when talking about a bug fix.
Aside from that, however, I see request.('GET', '/') and request.('GET', '/',
'') as clearly *different* from an API call standpoint, so I would in any case
preserve the existing behavior.

[issue18383] test_warnings modifies warnings.filters when running with -W default
Alex Shkop added the comment: The issue occurs only if C implementation of _warnings is available. It is caused by re-use of global filters variable from _warnings when warnings is being re-imported. So warnings modifies _warnings.filters on first import. Then, when you import warnings again it uses already modified version of _warnings.filters and adds same filter for the second time. I attach a simple patch that prevents duplicates in filters. I'm not sure if this is a best way to fix the problem, but it works. It certainly affects performance of filterwarnings(), but there shouldn't be a lot of filters anyway. Making filters a set() will solve the problem also, but will require API changes. Although I didn't find anywhere in documentation that warnings.filters should be a list, someone might rely on its .append() method. -- nosy: +ashkop Added file: http://bugs.python.org/file38301/issue18383_remove_dups.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18383 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue23564] Patch fixing sanity check for ordered fd sequence in _posixsubprocess.c
New submission from Hisham Muhammad: In Modules/_posixsubprocess.c, (the helper module for Lib/subprocess.py) there's a function called _sanity_check_python_fd_sequence which checks, as its comment says, if the fds in the sequence are all positive and sorted. The check to verify if it is sorted is incorrect (missing the update to the prev_fd variable), and also it is missing a test to see if fd's are repeated (which they shouldn't be, so the test should use = rather than ). The attached patch, written against Python 3.4.3 source code, fixes it. -- components: Extension Modules files: python-3.4.3-_posixsubprocess.c.fix.patch keywords: patch messages: 237061 nosy: Hisham Muhammad priority: normal severity: normal status: open title: Patch fixing sanity check for ordered fd sequence in _posixsubprocess.c versions: Python 3.4 Added file: http://bugs.python.org/file38302/python-3.4.3-_posixsubprocess.c.fix.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23564 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue23539] Content-length not set for HTTP methods expecting body when body is None
R. David Murray added the comment: Not to get into an API argument, but rather to convey some Python philosophy as I understand it: there *is* often a distinction in Python between the value 'None' and a boolean-False-value like ''. It is often the case in Python APIs that None means something different from other arguably-semantically-equivalent values. In this case I believe it is entirely logical that 'None' (the default value) for a method that does not normally take a body and makes a distinction based on Content-Length (or some other header) makes sense, and that explicitly saying I want an empty body, including the standard headers is actually a sensible Python API. If we were designing it from scratch with these issues in mind, we might well come up with exactly what we've got...or we might not, because wanting to specify an empty body on such a command is a really low probability event :) Regardless, we're constrained by backward compatibility here, so the question is moot. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23539 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue23539] Content-length not set for HTTP methods expecting body when body is None

I do understand the case that the the two examples look different from a
caller’s standpoint. However as a user, I’d expect the library to do the Right
Thing due to a deeper understanding of the theory behind the API that I’m
using. Perhaps it would have made more sense to default body to empty string
rather than None in which case there wouldn’t be a need for this distinction.
That said, I do understand the reasoning behind not breaking backwards
compatibility and it’s not a problem until reported and am not looking to get
into an API design argument (especially for something as low impact as what I
was proposing). So @James, I stand corrected :)
