[issue23794] http package should support HTTP/2

[Cory Benfield]

Cory Benfield added the comment:

I'm happy to talk about bringing hyper's HTTP/2 layer into http.client. It's 
worth noting that at this point I have no current plans to build a server into 
hyper, though if there was interest in using hyper as a baseline then I could 
take a swing at it.

[issue23797] Mac OS X locale setup in thread happens sometime after run() is called

[Barry Alan Scott]

New submission from Barry Alan Scott:

I'm seeing a random traceback when starting a new thread on Mac OS X 10.10.2 
with python 3.4.3 final.

Exception in thread Thread-1:
Traceback (most recent call last):
  File 
"/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/threading.py", 
line 920, in _bootstrap_inner
self.run()
  File 
"/Users/barry/wc/svn/pysvn-phoenix/WorkBench/Source/wb_background_thread.py", 
line 40, in run
self.app.log.info( 'BackgroundThread locale %r' % (locale.getlocale(),) )
  File 
"/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/locale.py", 
line 575, in getlocale
return _parse_localename(localename)
  File 
"/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/locale.py", 
line 484, in _parse_localename
raise ValueError('unknown locale: %s' % localename)
ValueError: unknown locale: UTF-8

Adding a time.sleep( 5 ) prevents the traceback.

Using _locale.setlocale( locale.LC_ALL, None ) to see the state with locale.py 
interfering it looks like the locale is being initialised in the thread after 
run() is called. (Make no sense to me, but I can reproduce).

I have failed to create a small script to show this bug.

[issue17515] Add sys.setasthook() to allow to use a custom AST optimizer

[Brett Cannon]

Brett Cannon added the comment:

The closing of this issue inspired me to think of a better way to do this, and 
I think providing something in importlib.util that accepted a NodeTransformer 
as an argument to a function that compiled source files to bytecode files would 
fill this issue thanks to PEP 488. It would mean that nothing is done 
dynamically and everything is done offline, but that also means startup costs 
are gone in regards to bytecode generation and it gets people to actually think 
about optimizations of Python instead of it just being an afterthought.

importlib.util.compile(path: Union[str, pathlib.Path], transformer: 
ast.NodeTransformer = None, *, optimization: Union[str, int] = None) -> 
pathlib.Path

[issue23792] help crash leaves terminal in raw mode

[R. David Murray]

R. David Murray added the comment:

SIGINT *is* keyboard interrupt.  Since less at least seems to ignore SIGQUIT I 
suppose also ignoring that would be reasonable, since the user (should) by 
analogy expect that behavior while the pager is active.  Note, however, that 
the signals we are ignoring are in the parent process, not the child as is the 
case for system.  So one can argue that letting the python process die when 
SIGQUIT is received would also be reasonable, and arguably is the less 
surprising option.

[R. David Murray]

R. David Murray added the comment:

This is probably related to or effectively a duplicate of issue 18378, which 
looks to be an Apple bug.

Do you have the problem if you remove the getlocale() call?

[issue23550] Add to unicodedata a function to query the "Quick_Check" property for a character

[Hammerite]

Hammerite added the comment:

For good measure, here is a patch that makes all of Berker's suggested 
stylistic changes, but applies them to the pre-existing code in 
makeunicodedata.py and unicodedata.c. So all of the existing docstrings are 
converted from '"...\n\' to '"...\n"' form, and the other property name arrays 
that were non-static are made static.

The behavior noted in Issue18378 isn't an Apple bug; it's a GNU vs BSD 
difference.  Can you avoid the problem by calling locale.getlocale() in the 
main program before creating any threads?

[issue23799] Join started threads in tests

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

When a test starts many threads in a loop, there is a chance that the starting 
thread will fail due to lack of memory. In this case all started threads left 
dangling and make MemotyError even more probably. They also can provoke dim 
error messages in this and in following tests. Proposed patch adds new helper 
function test.support.start_threads() that starts threads and then join started 
threads.

Some tests even hang without this patch.

Ryan,
For now I'll make the edits to pyconfig.h manually after downloading the zip

I'll do my best to get this done this weekend, but it may have to wait until

[issue23800] Support POSIX uselocale interface for thread-specific locale settings

[Ned Deily]

New submission from Ned Deily:

POSIX 2008 provides a system interface, uselocale, to set locales individually 
on a thread basis rather than just process global, as currently supported with 
locale.setlocale().  uselocale is supported in most current GNU libc, BSD, and 
OS X releases.  While there is currently a third-party package available in 
PyPI, it currently doesn't claim to support Python 3 and it would be good to 
have uselocale as part of the standard library where available.

[issue23787] sum() function docstring lists arguments incorrectly

[Wolfgang Maier]

Wolfgang Maier added the comment:

>This implies sum() should accept str, unicode, list, tuple, bytearray, buffer, 
>and xrange.

and in fact it *does* accept all these as input. It just refuses to add the 
elements of the sequence if these elements are of certain types. Of course, the 
elements of a string are strings themselves so this does not work:

>>> sum('abc', '')
Traceback (most recent call last):
  File "", line 1, in 
sum('abc', '')
TypeError: sum() can't sum strings [use ''.join(seq) instead]


compare with a bytes sequence in Python3, where the elements are ints:

>>> sum(b'abc', 0)
294


but strings are also perfectly accepatble as input if you do not try to add 
their str elements, but something else:

>>> class X (int):
def __add__(self, other):
return X(ord(other) + self)

>>> sum('abc', X(0))
294

=> the docs are right and there is no issue here.

[issue23801] cgi.FieldStorage has different (wrong?) behavior on Python3 than Python2

[Donald Stufft]

New submission from Donald Stufft:

While working on PyPI 2.0 (which is currently running Python 3) I discovered 
that ``setup.py upload`` was causing an exception. After tracing things I 
determined that the reason for this is that Python 3 fails to handle leading 
whitespace in a multipart body.

I've attached a minimum reproducer that runs without error on Python 2.6 and 
Python 2.7 which fails on Python 3.2, 3.3, and 3.4.

If I go into the cgi.py module and add a print() statement that will print the 
header of each part, I get output that looks like:

b'GHSKFJDLGDS7543FJKLFHRE75642756743254\r\nContent-Disposition: 
form-data; name="protcol_version"\r\n\r\n'
b'Content-Disposition: form-data; name="summary"\r\n\r\n'
b'Content-Disposition: form-data; name="home_page"\r\n\r\n'
b'Content-Disposition: form-data; name="filetype"\r\n\r\n'
b'Content-Disposition: form-data; name="content"; 
filename="jasmin-13.13.13.tar.gz"\r\n\r\n'

The first line of that is obviously suspicious since it includes the inner 
boundary marker. Looking at the Python 3.x code it throws away the first line 
off the fp and then proceeds to process the rest of the fp. However in this 
case the first line is just a blank b'\r\n'. Looking at the Python 2.7 code it 
throws away an entire first part, not just the first line.

I'm guessing that the "read first line and throw it away code" needs to 
continue reading lines until it's read enough lines to get to the boundary 
marker.
