[issue32962] test_gdb fails in debug build with `-mcet -fcf-protection -O0`

[STINNER Victor]

STINNER Victor  added the comment:

Oh I see. But currently, many test_gdb tests pass even with optimization. I 
dislike reducing the test coverage when Python is compiled with optimizations, 
just to support -mcet -fcf-protection.

Would it be possible to detect the special case "-mcet -fcf-protection" *and* 
optimizations, and only skip test_gdb in that case?

[issue33899] Tokenize module does not mirror "end-of-input" is newline behavior

[Ammar Askar]

New submission from Ammar Askar :

As was pointed out in https://bugs.python.org/issue33766 there is an edge case 
in the tokenizer whereby it will implicitly treat the end of input as a 
newline. The tokenize module in stdlib does not mirror the C code's behavior in 
this case.

tokenizer.c:

  ~/cpython $ echo -n 'x' | ./python
  --
  NAME ("x")
  NEWLINE
  ENDMARKER

tokenize module:

  ~/cpython $ echo -n 'x' | ./python -m tokenize
  1,0-1,1:NAME   'x'
  2,0-2,0:ENDMARKER  ''

The instrumentation to have the C tokenizer dump out its tokens is mine, can 
provide a diff to produce that output if needed.

[issue33900] collections.counter update method without argument gives misleading error

[Karthikeyan Singaravelan]

New submission from Karthikeyan Singaravelan :

There was a change made in collections.Counter that made it accept self as the 
first parameter and hence while doing *args in the method signature args[0] is 
always set as the self. Hence the check for `not args` becomes a no-op during 
collection_object.update() calls and the type error is not raised. This is only 
triggered when it's called as a class method like `Counter.update` and the 
error message is misleading "descriptor 'update' of 'Counter' object "needs an 
argument" which says update method of Counter object needs an argument though 
we are calling the method on class and also calling update on Counter object 
doesn't need an argument since counter_object.update() works fine as no-op. I 
think the error message could be improved since argument is not necessary for 
counter_object.update.

Relevant commit : 
https://github.com/python/cpython/commit/ae5cb214d2cd41d96943a0ef43a4e95bd9a10b7a#diff-f30cb98704c3ccaf71deaf5503f7f4a1R587

[issue33174] error building the _sha3 module with Intel 2018 compilers

[Christian Heimes]

Christian Heimes  added the comment:

I read the patch. The manual loop unrolling is ugly but mostly ok. But 
I'm -1 on the "-O0" option and won't accept the patch unless it works with 
standard optimization. sha3 is already slow. Without optimization, the 
algorithm grinds to a halt.

Did anybody contact Intel and reported the bug? It's clearly a bug in ICC. GCC, 
clang and MSVC compile the code just fine.

I made the patch. I'm not sure it's suitable to commit back as it is, as it 
unrolls a macro but there seems to be a choice of macro in the code (depending 
on certain conditions).

The problem is that icc can't handle a line that is so long.

I didn't log the bug with Intel - but I agree that it's a compiler bug and not 
a Python bug. I'll log it now...

What makes you think that it would be otherwise be able to load and execute 
such C extensions without any bugs?

There is no ABI except the stable ABI, and tp_flags isn't part of the stable 
ABI. 

PS : tp_finalize is in Python 3.4, but that doesn't really matter.

[issue33901] test_dbm_gnu.test_reorganize() failed on x86-64 High Sierra 3.x

[STINNER Victor]

STINNER Victor  added the comment:

size0=16777216 (16 MiB). On my Fedora 28, size0=12288 (12 KiB).

Even more strange: another test starts by removing the filename, just in case!?

def test_error_conditions(self):
# Try to open a non-existent database.
unlink(filename)
...

Maybe the setUp() method must fail if filename already exists?

The buildbot runs tests in subprocesses:
"Run tests in parallel using 2 child processes"

regrtest spawns child procsses which creates their own temporary empty current 
directory and TESTFN is related to the current directory. If the 
filename/database existed before test_reorganize(), it's likely a bug in 
test_dbm_gnu: but there is a single TestCase class with a tearDown() method 
which calls unlink(filename).

--

Maybe x86-64 High Sierra 3.x has a different dbm library version which always 
creates an empty database with 16 MiB preallocated on disk!?

PR 7791 makes the test less useful.

I suggest to replace 1 with size0 or max(size0, 1).

[STINNER Victor]

STINNER Victor  added the comment:

Serhiy Storchaka: "Did not increasing the size of the value fixed the test?"

Honestly, I don't understand the purpose of the test. Why does *Python* check 
such low level implementation detail, the exact file size used by gdbm? We are 
supposed to only test the API, no? If someone wants to change something else, I 
would suggest to remove test_reorganize().

[issue6280] calendar.timegm() belongs in time module, next to time.gmtime()

[oric]

oric  added the comment:

Please don't name it timegm which is such a stupid name (why not mgemit!).

I knows it comes from history but history had timelocal which has been replaced 
by mktime (and python has mktime and not timelocal) so please, call it mkgmtime

time.mkgmtime()

I think it would make things more clear.

[R. David Murray]

R. David Murray  added the comment:

I think it might be OK to document what goes in to the signature, but probably 
in a footnote, as it is somewhat of an implementation detail and could 
conceivably change.  We could then also add a caution about mtime imprecision 
being a particular risk on some file systems.  I wouldn't want to put such a 
caution in the main doc paragraphs, but in a footnote I think it would be OK.

[issue33902] entry_points/console_scripts is too slow

[George King]

New submission from George King :

On my newish macOS laptop using Python 3.6 or 3.7, a no-op script takes 3 times 
as long to invoke using the entry_points machinery as it does to invoke 
directly. Here are some exemplary times (best times after several tries).

$ time python3.6 entrypoint.py 

real0m0.047s
user0m0.033s
sys 0m0.010s

$ time python3.6 
/Library/Frameworks/Python.framework/Versions/3.6/bin/entrypoint

real0m0.153s
user0m0.129s
sys 0m0.020s

In this example, entrypoint.py consists of `def main(): pass`; the second 
script is that generated by `pip3 install ...`. I have confirmed that the `-e` 
flag to pip is not the culprit.

I look at a cprofile trace of the invocation and I do not see an obvious single 
culprit, but I'm not an expert at reading such traces either.

I know that there has been some previous debate about "how slow is slow", 
whether to try to improve import times, etc. I'm not trying to fan any flames 
here, but from a practical perspective, this discrepancy is showing up in 
developer tools that I'm writing, and is driving me to abandon entry_points in 
favor of less standard, less cross-platform install hackery in my setup.py 
scripts. An extra 0.1s per invocation is visibly detrimental to shell scripts 
calling out to installed python programs.

[issue33895] LoadLibraryExW called with GIL held can cause deadlock

[Steve Dower]

Steve Dower  added the comment:

What about existing code that assumes the GIL is already held?

Also, your patch addresses many more situations than raised here, most of which 
are unnecessary (GetProcAddress and GetModuleHandle don't block in the way that 
LoadLibrary and FreeLibrary may).

Perhaps the application needs a way to terminate its threads cleanly, other 
than simply letting them exit and assuming it will be fine?

[issue33903] Can't use lib2to3 with embeddable zip file

[Mickaël S .]

New submission from Mickaël S. :

As stated by https://bugs.python.org/issue24960, the bug should be fixed in 
3.6.5 (if it is the same, not sure).

Simple reproduction steps are:

1) Download and unzip python-3.6.5-embed-win32.zip.

2) Install pip (OK):
C:\Users\TestW764\python-3.6.5-embed-win32> python get-pip.py

3) In python36._pth, uncomment "import site".

4) Try to install anything else:

Do you think it is a sub-issue of 24960, something new or I bug from my side?

[issue33895] LoadLibraryExW called with GIL held can cause deadlock

[Tony Roberts]

Tony Roberts  added the comment:

GetProcAddress and GetModuleHandle do block in the same way as LoadLibrary and 
FreeLibrary - they acquire the loader lock too.

Yes, ideally the application would terminate its threads cleanly, however when 
Python is embedded in another application it may not have control on when or 
how the threads are terminated (see original problem description).

I would be surprised if there is any code that assumes the GIL is acquired 
during any of those functions. When going though the code I found that 
sometimes the GIL was acquired when calling one of those four functions and at 
other times it wasn't.

See 
https://docs.microsoft.com/en-us/dotnet/framework/debug-trace-profile/loaderlock-mda
 for a (possibly incomplete) list of functions that acquire the loader lock.

[issue33895] LoadLibraryExW called with GIL held can cause deadlock

[Steve Dower]

Steve Dower  added the comment:

Yeah, just after posting I remembered that the blocker is the loader lock and 
not filesystem/arbitrary code.


Still, "I don't think" isn't sufficient to justify making the change in 3.7 or 
earlier. If we can show that properly working code could never have assumed the 
GIL, then I guess it's fine, but otherwise it's too risky.

Making the change without any deprecation period in 3.8 is fine.

Ok, so can you please give the value of:

* sys.stdin.encoding
* sys.stdout.encoding
* sys.stderr.encoding
* os.device_encoding(0)
* os.device_encoding(1)
* os.device_encoding(2)
* locale.getpreferredencoding(False)

Maybe also the .errors attribute of sys.stdin, sys.stdout and sys.stderr.

[issue33895] LoadLibraryExW called with GIL held can cause deadlock

[Tony Roberts]

Tony Roberts  added the comment:

Sure, that's reasonable :)

For my case I have a usable workaround so not back porting it to < 3.8 is fine 
for me. My workaround will just leak the thread state if another thread is in 
__import__, which happens so rarely that it's not really a problem (but not 
rarely enough that blocking is acceptable!). The other cases changed in this PR 
would cause the same issue, but in practice for my application it's unlikely.

Thanks!

In some of these cases, it would be simpler to just remove the explicit dynamic 
linking. 3.6+ doesn't support XP, so CancelIoEx, CreateSymbolicLinkW, 
RegDeleteKeyExW, RegDisableReflectionKey, RegEnableReflectionKey, and 
RegQueryReflectionKey can be linked implicitly. 3.7+ doesn't support Vista, in 
which case GetMaximumProcessorCount can be linked implicitly. (It should be 
GetActiveProcessorCount. See issue 33166.) OTOH, ShellExecuteExW is loaded 
explicitly on purpose to avoid a static dependency on shell32.dll.

[issue33902] entry_points/console_scripts is too slow

[Barry A. Warsaw]

Barry A. Warsaw  added the comment:

This really isn't enough information to know exactly what's going on in your 
case, but there are things that are known to be slow for CLI startups.  
Probably the biggest contributor is pkg_resources.  Of course, that's a third 
party library that's popular for handling entry points, so it's not really a 
Python problem.  There are some other third party libraries on PyPI that may be 
more performant for you.  Entry point handling is something that I'd like to 
try to address in 3.8 in a manner similar to importlib.resources.

[issue33301] Add __contains__ to pathlib

[Antoine Pitrou]

Antoine Pitrou  added the comment:

Not a good idea IMHO.  Why would containment mean the existence of a file in a 
directory?  It could just as well mean that a certain path component is part of 
the path.

Also I don't understand what would e.g. `Path('/usr/bar') in Path('/etc/foo')` 
mean.

As for adding a .exists method to PurePath, I think you're missing the point of 
PurePath here (i.e. its operations *don't* do any IO whatsoever).

[issue33902] entry_points/console_scripts is too slow

[George King]

George King  added the comment:

Thanks Barry. My question then is, what relationship does cpython have with 
pip, setuptools, distutils and pkg_resources? Since pip comes bundled with 
Python now it seems a little bit closer than "3rd party". Thanks!

[issue33902] entry_points/console_scripts is too slow

[Barry A. Warsaw]

Barry A. Warsaw  added the comment:

"It's complicated" :)  But technically speaking they are all separate projects, 
so while there is synergy, CPython itself *imports* some of those to provide 
various tasks, but it doesn't lead their development.  You'll find a lot of the 
same players in all those projects though.

This might be a good resource: https://www.pypa.io/en/latest/

I hope you don't mind, but I am going to close this issue since it's not 
directly related to Python itself.  If you feel otherwise and/or can provide a 
reproducible test case, please do reopen it.

Thanks for your contribution to Python!

[issue33905] IDLE: stackbrowser.Stackbrowser should accept exception.

[Terry J. Reedy]

New submission from Terry J. Reedy :

Stackbrowser is currently initialized with a traceback and/or the sys.last_xyz 
attributes.  The latter are not set when unittesting;  the test framework 
somehow prevents this.  The tests needed are the ones that will be enabled by 
Stackbrower accepting an exception, which has everything needed.
