[issue33934] locale.getlocale() seems wrong when the locale is yet unset (python3 on linux)

[Nicolas Hainaux]

Nicolas Hainaux  added the comment:

I understand that the statement "when python starts, it runs using the C 
locale..." should not be correct anymore (and the doc should then be updated), 
but in fact this statement is still true on the systems I tested; only, the 
output of locale.getlocale() at start is in contradiction with the locale 
really set in fact.

It looks like the setting done by setlocale(LC_ALL, "") at an early stage is 
lost at some point (only locale.getlocale() seems to "remember" it).

For instance, my box locale is 'fr_FR.UTF-8', so the decimal point is a comma, 
but when starting python 3.7:


>>> import locale
>>> locale.str(2.4)
'2.4' # Wrong: if the locale in use is 'fr_FR.UTF-8', then 
'2,4' is expected instead
>>> locale.getlocale()
('fr_FR', 'UTF-8')
>>> locale.localeconv()
{'int_curr_symbol': '', 'currency_symbol': '', 'mon_decimal_point': '', 
'mon_thousands_sep': '', 'mon_grouping': [], 'positive_sign': '', 
'negative_sign': '', 'int_frac_digits': 127, 'frac_digits': 127, 
'p_cs_precedes': 127, 'p_sep_by_space': 127, 'n_cs_precedes': 127, 
'n_sep_by_space': 127, 'p_sign_posn': 127, 'n_sign_posn': 127, 'decimal_point': 
'.', 'thousands_sep': '', 'grouping': []}
>>>


Note that the output of localeconv() does match C locale, not 'fr_FR.UTF-8'.

Compare this with the outputs of locale.str() and locale.localeconv() when the 
locale is explicitly set at start:


>>> import locale
>>> locale.setlocale(locale.LC_ALL, '')
'LC_CTYPE=fr_FR.utf8;LC_NUMERIC=fr_FR.UTF-8;LC_TIME=fr_FR.UTF-8;LC_COLLATE=fr_FR.utf8;LC_MONETARY=fr_FR.UTF-8;LC_MESSAGES=fr_FR.utf8;LC_PAPER=fr_FR.UTF-8;LC_NAME=fr_FR.UTF-8;LC_ADDRESS=fr_FR.UTF-8;LC_TELEPHONE=fr_FR.UTF-8;LC_MEASUREMENT=fr_FR.UTF-8;LC_IDENTIFICATION=fr_FR.UTF-8'
>>> locale.str(2.4)
'2,4'   # Correct!
>>> locale.localeconv() # Output of localeconv() does match 'fr_FR.UTF-8' 
>>> locale
{'int_curr_symbol': 'EUR ', 'currency_symbol': '€', 'mon_decimal_point': ',', 
'mon_thousands_sep': '\u202f', 'mon_grouping': [3, 0], 'positive_sign': '', 
'negative_sign': '-', 'int_frac_digits': 2, 'frac_digits': 2, 'p_cs_precedes': 
0, 'p_sep_by_space': 1, 'n_cs_precedes': 0, 'n_sep_by_space': 1, 'p_sign_posn': 
1, 'n_sign_posn': 1, 'decimal_point': ',', 'thousands_sep': '\u202f', 
'grouping': [3, 0]}
>>>


Maybe the title of this issue should be turned to "at start, the C locale is in 
use in spite of locale.getlocale()'s output (python3 on linux)"?




As to the behaviour on Windows, I guess this is another topic (locales 
belonging to another world on Windows)... but it may be interesting to note 
that it complies with the current documentation: at start python 3.6 also uses 
the C locale, and the output of locale.getlocale() is consistent with that. 
Here is a test on Windows 10:

Python 3.6.3 (v3.6.3:2c5fed8, Oct  3 2017, 18:11:49) [MSC v.1900 64 bit 
(AMD64)] on win32

>>> import locale
>>> locale.getlocale()
(None, None)
>>> locale.localeconv()
{'decimal_point': '.', 'thousands_sep': '', 'grouping': [], 'int_curr_symbol': 
'', 'currency_symbol': '', 'mon_decimal_point': '', 'mon_thousands_sep': '', 
'mon_grouping': [], 'positive_sign': '', 'negative_sign': '', 
'int_frac_digits': 127, 'frac_digits': 127, 'p_cs_precedes': 127, 
'p_sep_by_space': 127, 'n_cs_precedes': 127, 'n_sep_by_space': 127, 
'p_sign_posn': 127, 'n_sign_posn': 127}
>>> locale.str(2.4)
'2.4'
>>> locale.getdefaultlocale()
('fr_FR', 'cp1252')

[issue24567] random.choice IndexError due to double-rounding

[Tim Peters]

Tim Peters  added the comment:

There are a couple bug reports here that have been open for years, and it's 
about time we closed them.

My stance:  if any platform still exists on which "double rounding" is still a 
potential problem, Python _configuration_ should be changed to disable double 
rounding on such platforms (there's usually a C compiler flag that can make 
this happen, but even if there isn't a couple lines of inline assembler could 
be added at Python startup to set the Pentium's FPU "precision control" bits to 
"round to 53 bits" mode).

`random` is a red herring here!  We don't want gratuitously different results 
across 754 boxes in any operations.

Still, I firmly believe they’re a wart being abused for purposes they weren’t 
really intended for.  It’s a trick of implementation that lines beginning with 
`import` are exec’d.  That being said…

+1 on working on *much* better debuggability and discoverability for .pth files 
first, and then consider their eventual deprecation, replacement, and/or 
removal.

[issue24567] random.choice IndexError due to double-rounding

[Raymond Hettinger]

Raymond Hettinger  added the comment:

Attaching a patch for 3.6 and 3.7.  Haven't had a chance to run timings yet.  
Since it involves adding code to the inner loop, presumably it will have a 
noticeable affect on speed.  Am not sure how to test this (I don't seem to be 
able to reproduce the OP's problem on any system I have access to).  I'm not 
even sure whether the double rounding still exists any extant platform and if 
so whether we could just turn it off as part of the configuration.

At any rate, I don't think the code in 2.7 should change at all.  That tool is 
almost at end-of-life and we should be very conservative with it at this point.

[issue33089] Add multi-dimensional Euclidean distance function to the math module

[Tim Peters]

Tim Peters  added the comment:

Raymond, I'd say scaling is vital (to prevent spurious infinities), but 
complications beyond that are questionable, slowing things down for an 
improvement in accuracy that may be of no actual benefit.

Note that your original "simple homework problems for kids to machine learning 
and computer vision" doesn't include cases where good-to-the-last-bit accuracy 
is important, but at least in machine learning and computer vision apps 
primitives may be called an enormous number of times - "speed matters" to them.

Perhaps add an optional "summer" argument defaulting to __builtins__.sum?  Then 
the user who wants to pay more for tighter error bounds can pass in whatever 
they like, from a raw Kahan summer, through one of its improvements, to 
math.fsum.  There just isn't a "one size fits all" answer.

Pablo Galindo Salgado  added the comment:

I have modified the PR to avoid creating an extra pipe in the tracker (the pipe

./python -m test test_multiprocessing_fork -v -m test_semaphore_tracker_sigint 
-R 3:3

I had to assure that we restart the tracker in the test so it does not reuse a 
closed file descriptor.

continuously reading from the original one and therefore we cannot use the same

[issue33945] concurrent.futures ProcessPoolExecutor submit() blocks on results being written

[Thomas Moreau]

Thomas Moreau  added the comment:

This behavior results from the fact that in 3.6, the result_queue is used to 
pass messages to the queue_manager_thread. This behavior has been changed in 
3.7 as we rely on a _ThreadWakeup object.

In 3.6, when the result_queue is filled with many large objects, the call to 
result_queue.put(None) will hang while the previous objects are being handled 
by the queue_manager_thread, causing a latency in the submit.

@taleinat Sadly, if the semaphore_tracker receives an invalid command, it 
raises and dies, making the test impossible:

 cmd, name = line.strip().split(b':')
 if cmd == b'REGISTER':
 cache.add(name)
 elif cmd == b'UNREGISTER':
 cache.remove(name)
 else:
 raise RuntimeError('unrecognized command %r' % cmd)

[issue33468] Add try-finally contextlib.contextmanager example

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

The entirely abstract example LGTM.

As for concrete real word examples, the possible one is changing the current 
working directory:

cwd = os.getcwd()
try:
os.chdir(target_dir)
yield
finally:
os.chdir(cwd)

[issue33927] Allow json.tool to have identical infile and outfile

[Rémi Lapeyre]

Rémi Lapeyre  added the comment:

Hi Pablo, while this patch should fix both problems, I'm not sure how to write 
a regression test for this, `assert_python_ok` in 
https://github.com/python/cpython/pull/7865/files#diff-7d4645839a05727ebdf39226fd56e29cR97
 forks the interpreter so I'm not sure I can check for unclosed fd during the 
test.

Should I call 
https://github.com/remilapeyre/cpython/blob/04b2ade751b318460c1f0f9566676ef519358328/Lib/json/tool.py#L18
 directly and mock `io.open` and `os.close`?

[issue33468] Add try-finally contextlib.contextmanager example

[Nick Coghlan]

Nick Coghlan  added the comment:

Similar to closing, we have dedicated context managers for stdout and stderr 
redirection now: 
https://docs.python.org/3/library/contextlib.html#contextlib.redirect_stdout

Redirecting stdin could be a good example though, since we've so far chosen not 
to provide a standard context manager for that (it's a sufficiently uncommon 
use case that we haven't seen the need to add it directly).

[issue33466] Distutils does not support the compilation of Objective-C++ (“.mm”) files

[Ronald Oussoren]

Ronald Oussoren  added the comment:

Patch looks good to me, and back porting to 3.6/3.7 should be safe enough.

I haven't merged yet because I need to study the devguid a bit before I do so 
(especially w.r.t. back porting)

[issue33613] test_multiprocessing_fork: test_semaphore_tracker_sigint() fails with -W error

[Tal Einat]

Tal Einat  added the comment:

You can know that the semaphore tracker is running by sending it an invalid 
command and seeing the error written to stderr.  The semaphore tracker either 
inherits sys.stderr from the parent process (if possible) or uses its own.  
This is a bit of a hack, but might be worth it to avoid another wasted second 
on every run of the test suite.

[issue32142] heapq.heappop - documentation misleading or doesn't work

[Raymond Hettinger]

Raymond Hettinger  added the comment:

We could apply David Murray's suggested wording but I don't think it would 
actually help anyone.  There are worked out examples from basic to advanced and 
a detailed section on the theory as well.

ISTM, that prior to reading the docs, the OP likely already had an incorrect 
mental model that caused the misreading of "maintaining" as "restoring".

For the most part, these docs have stood the test of time.  I don't see any 
StackOverflow questions about this either.  I recommend marking this as closed 
(the OP seems to now have a clear understanding of this so there isn't an open 
problem to be resolved).

[issue32554] random.seed(tuple) uses the randomized hash function and so is not reproductible

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

This is what I meant. Emit a deprecation warning for input types other than 
explicitly supported types (but I didn't think about float), and raise an error 
in future.

[Raymond Hettinger]

Raymond Hettinger  added the comment:

> Maybe deprecate using a hash?

Any deprecation will likely break some existing code, but it would be nice to 
restrict inputs types to int, float, bytes, bytearray, or str.  Then we could 
remove all reference to hashing.

[issue25478] Consider adding a normalize() method to collections.Counter()

[Raymond Hettinger]

Raymond Hettinger  added the comment:

Vedran, Counters do explicitly support floats, decimals, ints, fractions, etc. 

Also, total() needs to be a method rather than a property to be consistent with 
the existing API and for clarity that a computation is being performed (as 
opposed to looking up a running total or other cheap operation).

[Raymond Hettinger]

Raymond Hettinger  added the comment:

I propose this, "Distinct argument patterns may be considered to be distinct 
calls with distinct results even if the underlying function sees them as 
equivalent calls."

[issue33951] IDLE test failing only when called by itself: HighPageTest.test_highlight_target_text_mouse

[Tal Einat]

New submission from Tal Einat :

The issue occurs when running the following on Windows 10 Pro 64-bit on the 
latest master branch (ea737751b10fff752aafed0231e8a02b82ba365d):

python -m test -ugui -m test_highlight_target_text_mouse test_idle

(This test failed for perhaps an unrelated reason on Travis CI for GH-7887.   I 
encountered the issue while investigating that failure.)
