[issue24921] Operator precedence table in 5.15 should be highest to lowest precedence
New submission from Joseph Schachner: We should not make people who need to read Python documentation do an extra transformation in their heads to correctly understand that in section 5.15 higher precedence is at the bottom of the table and lower precedence is at the top. Because the documentation has this table inverted from the way it is usually presented in other references, one of the top hits in a Google search shows an instructor felt the need to make a version in the usual high to low precedence order to show students, see: http://www.mathcs.emory.edu/~valerie/courses/fall10/155/resources/op_precedence.html That version is so much more comfortable for me to read, it seems almost strange, but it is true. Please consider changing section 5.15 so it would not need the top paragraph explaining that the table order is not what the reader probably expects, instead just present the table as at the link above - in the order the reader does expect - higher precedence on top, lower on the bottom. That only needs two short sentences of explanation that don't make the reader think wait ... what? -- assignee: docs@python components: Documentation messages: 249046 nosy: Joseph Schachner, docs@python priority: normal severity: normal status: open title: Operator precedence table in 5.15 should be highest to lowest precedence versions: Python 2.7 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24921 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue24922] assertWarnsRegex doesn't allow multiple warning messages
New submission from Cal Leeming: There was a discussion/patch in #9754 [1]. This allows for multiple warning types as a tuple, e.g.; self.assertWarnsRegex((DeprecationWarning, RuntimeWarning), ^E1000:) However, it does not allow testing for multiple warning messages, e.g.; expect = ((UserWarning, ^W1000), (UserWarning, ^W1001)) self.assertWarnsRegex(*expect) This is slightly unexpected, as `test.support.check_warnings` allows this behaviour, e.g. expect = ((UserWarning, ^W1000), (UserWarning, ^W1001)) check_warnings(*expect) Therefore I am proposing that `assertWarnsRegex` and `assertWarns` are modified to reflect the behaviour of `check_warnings`, whilst ensuring backwards compatibility. (e.g. if arg[0] is tuple, use new approach, otherwise use old approach).

Alecsandru Patrascu added the comment: I modified the patches after the review made by Brett (python2.7-pgo-v02.patch and python3.6-pgo-v02.patch): - removed the call to pybench - left the PGO steps as optional. To use it we run make profile-opt - in the initial patches, I left out test_hashlib because in our benchmarks we did not see any gain by applying PGO to the hash functions. It is not harmful and we can let it there or skip it. Nevertheless, in order not to create confusions about it, I removed that parameter from the patch. I also added the patches for Mac exclusively (python2.7-pgo-v02-mac.patch and python3.6-pgo-v02-mac.patch). You must have llvm-profdata installed and in your path (in /Library/Developer/CommandLineTools/usr/bin/) to use it. I tested on Yosemite and it compiles fine with clang.

[issue24923] Append system paths in setup.py instead of prepending
New submission from Chris Hogan: Setup.py evaluates what's given in LDFLAGS and CPPFLAGS and CFLAGS. These variables are the usual mechanism to communicate custom paths/libs/defs to a build process. However, setup.py puts system paths in front of custom paths which makes it impossible to use these variables for providing search paths to overwrite system settings. This patch puts system paths at the end of the list to avoid this problem.

[issue16123] IDLE - deprecate running without a subprocess
Terry J. Reedy added the comment: Torgil, thank you for the interesting feedback. I will respond to your four paragraphs slightly out of order. 1. Starting Idle with '-n', I verified that running 'print(a)' from the editor works after entering 'a=1' in the shell. The intended purpose of the editor is to edit files that run as is. From this viewpoint, the carryover behavior is a bug. Idle's original single process mode, now accessed with -n, only remains because communicating with a subprocess via sockets turns out to be a bit unreliable. 3. Using an editor as a extension of the shell is an alternate use. It does not have to be tied to -n. I have been thinking about alternate run modes and added 'run as input' to my list. A useful version might be this: don't require a name for the editor buffer; don't restart; enter each statement at a prompt and run as if typed. The latter would make all the code run in Shell visible and add each statement to the history list. 2. I am a bit puzzled by your matlab comment. When tkinter code is run from editor in a separate process, it successfully grabs keyboard and mouse input. (One of the reasons for the shift from 1 to 2 processes was to disentangle user tkinter guis from the Idle tkinter gui.) On the other hand, running import msvcrt; k = msvcrt.kbhit() on Windows does not work with either 1 or 2 processes because the Idle gui retains input focus. If you want to pursue this, please open a new issue on the tracker or post to the idle-sig list or its news.gmane.org mirror gmane.comp.python.idle. In either case, say more about what 'not work' means. 4.This issue was opened before PEP 434 and before 2.7 maintenance was extended from 5 years (expiring now as 3.5 is released) to 10 years. Hence the deprecation notice was not added to 2.7. I do not expect this to change. -- versions: +Python 3.6 -Python 3.5 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16123 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue16379] SQLite error code not exposed to python
Daniel Shahaf added the comment:
What's the reasoning behind offering a error code to name mapping?
Allowing code that runs into an error to print the error name rather than its
numeric value. This saves whoever reads the error message having to look it up
himself.
his seem problematic to me. In case a newer SQLite version introduces a new
error code, this error code cannot be found in the mapping. I propose to
leave this out in order to not have this problem.
Otherwise we will have people depending on any error code being able to be
found in this mapping.
Then people shouldn't depend on the mapping being complete. Let's keep the
mapping and document that people should only use it as
`sqlite3.errorcode.get(...)`, never as `sqlite3.errorcode[...]`.
Or if that's not a good API, we could encapsulate the incompleteness of the
mapping into a small wrapper function:
def something(errorcode):
return sqlite3.errorcode.get(errorcode,
sqlite3 error {!d}.format(errorcode))

[issue24927] multiprocessing.Pool hangs forever on segfault
Jonas Obrist added the comment: So the reason this is happening is very simple: When using Pool.apply, the task (function) is sent to the task queue, which is consumed by the worker. At this point the task is in progress. However, the worker dies without being able to finish the task or in any other way tell the Pool that it can't finish the task. The actual process is then ended by the Pool but the task is still in limbo, so any attempt at getting a result will hang forever. I'm not sure there's a straight forward way to solve this (the ways I can think of from the top of my head involve adding quite a bit of overhead to the Pool so it keeps track of which process/worker is handling which task at a given time, so if it exits prematurely this task can be finished), but at the very least this case should be documented I think. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24927 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

ValueError: time data '2015/16/5' does not match format '%Y/%m/%d'
However, if we relax the regex to not check the range and allow datetime to
handle it:
'm': r(?Pm\d{1,2})
The error will be handle in datetime instead and the error will be much more
helpful:
ValueError: month must be in 1..12
Please consider relaxing the regex for numeric ranges in _strptime.TimeRE.

[issue24294] DeprecationWarnings should be visible by default in the interactive REPL
Robert Collins added the comment: On testing this - I don't think subprocess tests are necessarily needed. The scenarios are these (from Nick's comment): Test frameworks. - there are two in the standard library. unittest and doctest. - unittest's code paths end up going through 'TestProgram'. - doctest via 'testmod'. - so alter the warning configuration in those APIs to enable both DeprecationWarning and PendingDeprecationWarning. I don't think (right now anyhow :)) that we need a 'do not do this' flag in them.. Interactive REPL. This includes IDLE in my opinion. - there are three here IIRC - IDLE and the cPython and a helper module (which may or may not be the REPL for ./python - I haven't climbed through that code in ---ages---). - Again here I'd just enable DW in those code paths. Don't worry about whether its a tty or not: thats irrelevant. If the REPL enters, its the REPL and we should treat it like a user. If someone is driving the REPL programattically its likely one of: a remote session - so they should see it - or its a test harness - so they should see it. Everything else. Don't change anything here. On docs: yes, we should update the docs for: - each changed module - the warnings module itself. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24294 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue24305] The new import system makes it impossible to correctly issue a deprecation warning for a module
Larry Hastings added the comment: If this has been broken since 3.3, I don't think it's a release blocker for 3.5. I'm willing to consider it a bug and accept a fix, but I'd prefer it to be as low-risk as possible (aka the Python version). Can someone fix the regressions?

[issue24305] The new import system makes it impossible to correctly issue a deprecation warning for a module
Nathaniel Smith added the comment: I still don't quite understand: what is the user-perceived result of this change? Module authors issuing a DeprecationWarning can now use stacklevel=2 instead of stacklevel=10? Exactly. There are a lot of deprecated modules in the wild, and the correct way to mark a module as deprecated is by writing warnings.warn(This module is deprecated!, stacklevel=2) at the top-level of your module. Except that in Python 3.3 you have to use stacklevel=10, and in Python 3.4 you have to use stacklevel=8, and I haven't checked what you need in Python 3.5 but it may well be different again, because it depends on internal implementation details of the import system. Fortunately AFAICT from some code searches no-one is actually depending on this though; instead everyone just writes stacklevel=2 and gets the wrong result. (This is made more urgent b/c people are increasingly relying on the stacklevel information to filter whether they even see the DeprecationWarning. E.g. I've seen multiple test suites which register a warnings filter that displays DeprecationWarnings iff they are attributed to the package-under-test, and IPython now shows deprecation warnings by default if the warning is attributed to interactive code -- see issue 24294. So there's a good chance that users will only find out that the module they are using is deprecated if the stacklevel= is set correctly.) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24305 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue24305] The new import system makes it impossible to correctly issue a deprecation warning for a module
Nathaniel Smith added the comment: You're right, impossible is a slight exaggeration :-). As an alternative, every package could indeed carry around a table containing the details of importlib's call stack in every version of Python. (I also haven't checked whether it's consistent within a single stable release series. I guess we could add a rule that 3.5.x - 3.5.(x+1) cannot change the number of function calls inside the importlib callstack, because that is part of the public API, but I have less than perfect confidence that this rule has been enforced strictly in the past, and I don't think I'd want to be the one in charge of enforcing it in the future.) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24305 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue24305] The new import system makes it impossible to correctly issue a deprecation warning for a module
Larry Hastings added the comment:
Is it really *impossible* to correctly issue a deprecation warning for a
module, as the title asserts? Or does the new import system simply make it
*tiresome*?
if sys.version_info.major == 3 and sys.version_info.minor == 4:
stacklevel = 8
elif sys.version_info.major == 3 and sys.version_info.minor == 4:
stacklevel = 10
else:
stacklevel = 2 # I bet they fixed it in 3.6!
warnings.warn({} is deprecated.format(__name__), DeprecationWarning,
stacklevel=stacklevel)
That's Python for you, doing six impossible things before breakfast.

[issue24932] Migrate _testembed to a C unit testing library

The specific unit testing library that prompted this idea was cmocka, which is used by libssh, sssd and cwrap: https://cmocka.org/ cwrap in turn is used by the Samba team to mock out network interfaces and other operations using LD_PRELOAD: https://cwrap.org/ We don't necessarily have to use those particular libraries, I'm just filing this issue to capture the idea of improving our C level unit testing capabilities, and then updating regrtest to better capture and report those results (currently there are just a couple of tests in test_capi that call the _testembed executable) -- components: Tests messages: 249106 nosy: encukou, eric.snow, ncoghlan priority: normal severity: normal status: open title: Migrate _testembed to a C unit testing library type: enhancement ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24932 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue24931] _asdict breaks when inheriting from a namedtuple
Raymond Hettinger added the comment:
For __dict__, I'm not sure what the right behavior should by for subclasses
that don't define __slots__. In Python 3, the __dict__ is returning the dict
for the subclass. This might be the correct and most desirable behavior:
class Point(namedtuple('_Point', ['x', 'y'])):
pass
a = Point(3, 4)
a.w = 5
a.__dict__
{'w': 5}
If we leave the __dict__ behavior as is in Py3, then we still need to get
_asdict() back to its documented behavior. For that, we would need to
disconnect it from __dict__ by restoring the Py2.7 code for _asdict():
def _asdict(self):
'Return a new OrderedDict which maps field names to their values'
return OrderedDict(zip(self._fields, self))
All this needs to be thought-out carefully. Putting in __dict__ support
originally looked like a bugfix to get vars() working correctly, but it caused
problems with pickling which then led to the addition of __getnewargs__. It
seems that defining __dict__ leads to problems no matter how you do it.
My inclination is to remove __dict__ and __getewargs__ from the namedtuple
definition entirely and return to a simpler state of affairs that is easier to
reason about and less likely to lead to unexpected behaviors like the one in
this bug report.
One note: using the Py2.7 namedtuple code in Python3 still doesn't restore the
old behavior. Something else in the language appears to have changed (causing
the subclasses' __dict__ to take precedence over the inherited __dict__
property).
