[issue21016] trace: $prefix and $exec_prefix improperly replaced on Fedora

2020-02-12 Thread Ben Boeckel


Ben Boeckel  added the comment:

Thanks!

Should I file a new issue for the other (less urgent) problem mentioned at the 
bottom or is it not really worth fixing?

[issue39622] KeyboardInterrupt is ignored when await asyncio.sleep(0)

2020-02-12 Thread Zhibin Dong


New submission from Zhibin Dong :

As shown in the code, when 0 is passed to asyncio.sleep function, sometimes the 
program does not exit when I press . I must press  again to 
close the program. However, when a number, such as 0.01, which is bigger than 
0, is passed to the sleep function, the program will exit as expected when I 
press  just once.

Is there any bug or just a wrong way to use? Thanks.

[issue39601] brace escapes are not working in formatted string literal format specifications

2020-02-12 Thread Vedran Čačić

Vedran Čačić  added the comment:

I can't help with the issue itself (though I must say that I philosophically 
don't believe in "sailed off ships" -- in the limit, Python must be the best it 
can be, though it can take decades to get there), but I can help you with the 
error message. It simply tries to take {{x}} as your v (expression to be 
formatted). That is, a set containing a set containing x. But since sets 
themselves are not hashable (being mutable), they cannot be contained in sets 
(that's why frozensets were invented).

[issue39620] PyObject_GetAttrString and tp_getattr do not agree

2020-02-12 Thread Andy Lester


Andy Lester  added the comment:

Do you know why it was reverted?  (Granted, it was 15 years ago...)

It looks like the original changeset is trying to address at least two 
different problems with non-const string literals.  My ticket here is focusing 
only on getattrfunc and setattrfunc.  The handling of all the kwlist is a 
separate issue, that I'm about to write up as a different ticket.

[issue39620] PyObject_GetAttrString and tp_getattr do not agree

2020-02-12 Thread Andy Lester


New submission from Andy Lester :

PyObject_GetAttrString(PyObject *v, const char *name)

typedef PyObject *(*getattrfunc)(PyObject *, char *)

The outer PyObject_GetAttrString takes a const char *name, but then casts away 
the const when calling the underlying tp_getattr.  This means that an 
underlying function would be free to modify or free() the char* passed in to 
it, which might be, for example, a string literal, which would be a Bad Thing.

The setattr function pair has the same problem.

The API doc at https://docs.python.org/3/c-api/typeobj.html says that the 
tp_getattr and tp_setattr slots are deprecated.  If they're not going away 
soon, I would think this should be addressed.

Fixing this in the cPython code by making tp_getattr and tp_setattr take const 
char * pointers would be simple.  I don't have any idea how much outside code 
it would affect.

[issue1812] doctest _load_testfile function -- newline handling seems incorrect

2020-02-12 Thread Éric Araujo

Éric Araujo  added the comment:

Ah, I got it wrong, get_data itself uses `rb`, not default `r`.
It makes sense given that package data could be any kind of file, not 
necessarily text.  Too bad there isn’t a `get_text(encoding)` method in the 
loader API!

With Python 3’s rich IO system, isn’t there a quick and correct way to get a 
text file from a bytes stream?  TextIOWrapper?

[issue1812] doctest _load_testfile function -- newline handling seems incorrect

2020-02-12 Thread Éric Araujo

Éric Araujo  added the comment:

Allow me to ask a maybe very naive question:

Wouldn't it be possible to fix the problem at the source, that is, use 
`open(filename, "rU")` in the two spots you found rather than doing ad-hoc line 
ending translation?

(I get that the second one uses `rb` at the moment, so switching from bytes to 
str is not just a one-liner there)

Personally I'm enjoying these BLAKE3 status updates, and I wouldn't mind at all 
being kept up-to-date during BLAKE3's development via messages on this issue.  
But, given the tenor of the conversation so far, I'm guessing Python is gonna 
hold off until BLAKE3 reaches 1.0.

Where else is ftruncate used in CPython that this could similarly trigger a

[issue39298] add BLAKE3 to hashlib

2020-02-12 Thread Jack O'Connor


Jack O'Connor  added the comment:

Version 0.2.0 of the BLAKE3 repo includes optimized assembly implementations. 
These are behind the "c" Cargo feature for the `blake3` Rust crate, but 
included by default for the internal bindings crate. So the easiest way to 
rerun our favorite benchmark is:

git clone https://github.com/BLAKE3-team/BLAKE3
cd BLAKE3
git fetch
# I rebased this branch on top of version 0.2.0 today.
git checkout origin/bench_406668786
cd c/blake3_c_rust_bindings
# Nightly is currently broken for unrelated reasons, so
# we use stable with this internal bootstrapping flag.
RUSTC_BOOTSTRAP=1 cargo bench 406668786

Running the above on my machine, I get 2888 MB/s, up another 12% from the 0.1.3 
numbers. As a bonus, we don't need to worry about the difference between GCC 
and Clang.

These new assembly files are essentially drop-in replacements for the 
instruction-set-specific C files we had before, which are also still supported. 
The updated C README has more details:

[issue37685] Fix equality checks for some types

2020-02-12 Thread Serhiy Storchaka

Serhiy Storchaka  added the comment:

Thank you Łukasz. I considered this as a bug fix, but was not sure that we 
should fix these bugs. They were here from the beginning.

Josh, as for using total_ordering, I think it is a different issue. I did not 
want to change the behavior except fixing bugs (and raising an error or not 
supporting comparison with objects which support comparison when used at LHS 
looks like a bug). Feel free to open separate issues for using total_ordering 
or changing its semantic.

[issue24916] In sysconfig, don't rely on sys.version format

2020-02-12 Thread STINNER Victor


STINNER Victor  added the comment:

The "py_version" variable of sysconfig is discussed since 2015 but... it's 
unused. It is supposed to build paths. Does it really make sense to build a 
path which contains "+"? It can confuse some application which may associate a 
special meaning to "+".

What about simply removing this variable? Does anyone know if it's used in the 
wild?

To me it sounds surprising to have a different path for alpha, beta and release 
candidate releases. Usually, Python paths only contain MAJOR.MINOR versions, no 
alpha, beta or rc marker. Nor "+" marker.

[issue39618] logger.exception with default message

2020-02-12 Thread Denis Vieira


New submission from Denis Vieira :

On my Python projects i like to use the logger.exception() method without any 
other message. 

I'm forced to send an empty string on every call.
logger.exception('')

It would be nice the exception method have the expected parameter "msg" with an 
default value ('').

[issue39617] max_workers argument to concurrent.futures.ProcessPoolExecutor is not flexible enough

2020-02-12 Thread sds


New submission from sds :

The number of workers (max_workers) I want to use often depends on the server 
load.
Imagine this scenario: I have 64 CPUs and I need to run 200 processes.
However, others are using the server too, so currently loadavg is 50, thus I 
will set `max_workers` to (say) 20. 
But 2 hours later when those 20 processes are done, loadavg is now 0 (because 
the 50 processes run by my colleagues are done too), so I want to increase the 
pool size max_workers to 70.
It would be nice if it were possible to adjust the pool size depending on the 
server loadavg when a worker is started.
Basically, the intent is maintaining a stable load average and full resource 
utilization.

2020-02-12 Thread STINNER Victor


STINNER Victor  added the comment:

> posix_user:
> 
> * stdlib: '~/.local/lib64/python3.9'
> * platstdlib: '~/.local/lib64/python3.9'
> * platlib: '~/.local/lib64/python3.9/site-packages'

Honestly, I have no idea how posix_user is used.

~/.local/lib64/ directory doesn't exist on my work machine, whereas I'm 
installed various Python modules and applications.

In practice, ~/.local/lib/ is used on Fedora, even if posix_user scheme uses 
~/.local/lib64/. Examples:

* pure Python: ~/.local/lib/python3.7/site-packages/pip/__main__.py
* C extension: 
~/.local/lib/python3.7/site-packages/typed_ast/_ast3.cpython-37m-x86_64-linux-gnu.so

So changing posix_user should have no impact on end users.


I also tested a legacy "python3 setup.py install" to install a C extension, it 
also lands into ~/.local/lib:

~/.local/lib/python3.7/site-packages/test_cext-0.0.0-py3.7-linux-x86_64.egg/test_cext.cpython-37m-x86_64-linux-gnu.so

The setup.py uses setuptools.


Miro:

Yeah, it seems like pip install adopted Debian multiarch naming: 
"x86_64-linux-gnu" triplet in "_ast3.cpython-37m-x86_64-linux-gnu.so" filename.

I am still not sure about the this one. I know that I have mentioned a

[issue1294959] Problems with /usr/lib64 builds.

2020-02-12 Thread STINNER Victor

STINNER Victor  added the comment:

Summary:

* This issue is mostly about pushing a 16-years old patch from Fedora and SuSE 
to Python upstream. Other Linux distributions use different solutions to 
support multiple architectures in the same filesystem. For example, Debian and 
Ubuntu uses "Multiarch" which continues to use /usr/lib/ for 32-bit and 64-bit 
x86 architecture (x86 and x86-64).

* I pushed the non controversial part of PR 3698: fix pydoc and trace modules 
to use sysconfig to get the stdlib path

* CI tests pass on PR 18381.

* Matthias Klose asked to not add another sys attribute, but Jan Matějek 
explained that the option value is needed to import the sysconfig module. 
Moreover, the option value is needed in the site module and we are trying to 
avoid "import sysconfig" in site since it would slowdown Python startup time.

* I chose "./configure --with-python-libdir" and "sys.python_libdir" names. PR 
3698 uses "./configure --with-custom-platsubdir" and 
sysconfig.get_config_var('platsubdir') names. Other proposed names: sys.lib, 
os.lib_dir. It was proposed to drop "custom" from "./configure 
--with-custom-platsubdir" option name.

Python use many paths. The sysconfig module is a good starting point to 
discover them all in the _INSTALL_SCHEMES directories. PR 18381 changes the 
following paths:

* posix_prefix: stdlib, platstdlib, platlib
* posix_user: stdlib, platstdlib, platlib


Examples on Fedora:

* pure Python: /usr/lib64/python3.7/os.py
* C extension: 
/usr/lib64/python3.7/lib-dynload/_multiprocessing.cpython-37m-x86_64-linux-gnu.so

Examples on SuSE:

* pure Python: /usr/lib64/python3.7/os.py

Ubuntu 16.04:

* pure Python: /usr/lib/python3.5/os.py
* C extension: 
/usr/lib/python3.5/lib-dynload/_multiprocessing.cpython-35m-x86_64-linux-gnu.so

[issue29620] unittest.TestCase.assertWarns raises RuntimeEror if sys.modules changes size

2020-02-12 Thread Maximilian Peters


Maximilian Peters  added the comment:

Ran into the same issue using Python 3.6.8 [GCC 5.4.0 20160609] on Linux.

The same code worked on Windows 10 with Python 3.7 32-bit and 64-bit.

[issue39615] cpython/abstract.h not compatible with C90

2020-02-12 Thread Eric V. Smith


Eric V. Smith  added the comment:

PEP 7 says that this is allowed:

Python versions greater than or equal to 3.6 use C89 with several select C99 
features:
...
- intermingled declarations

So I don't think these changes should be accepted.

[issue39567] Add audit for os.walk(), os.fwalk(), Path.glob() and Path.rglob()

2020-02-12 Thread Steve Dower


Steve Dower  added the comment:

Yes, they should be.

They can also be backported to 3.8 - it was deliberate in the original PEP that 
adding new events is not a breaking change or a new feature.

[issue39615] cpython/abstract.h not compatible with C90

2020-02-12 Thread Peter Eisentraut


New submission from Peter Eisentraut :

Some inline functions use mixed declarations and code.  These end up visible in 
third-party code that includes Python.h, which might not be using a C99 
compiler.

Example:

In file included from 
/Users/peter/python-builds/3.9/include/python3.9/abstract.h:843,
 from 
/Users/peter/python-builds/3.9/include/python3.9/Python.h:147,
 from plpython.h:59,
 from plpy_typeio.h:10,
 from plpy_cursorobject.h:8,
 from plpy_cursorobject.c:14:
/Users/peter/python-builds/3.9/include/python3.9/cpython/abstract.h:74:5: 
warning: ISO C90 forbids mixed declarations and code 
[-Wdeclaration-after-statement]
   74 | Py_ssize_t offset = tp->tp_vectorcall_offset;

[issue37685] Fix equality checks for some types

2020-02-12 Thread Łukasz Langa

Łukasz Langa  added the comment:

Unfortunately, we released 3.8.0, 3.8.1, and 3.8.2rc1 without this change. It 
seems too late in the release cycle to introduce this change. I'd feel better 
seeing it in 3.9 only. Sorry that we didn't act in time to include this in 
3.8.0.
