[issue26032] Use scandir() to speed up pathlib globbing

[Ben Hoyt]

Ben Hoyt added the comment:

Guido, I've made some tweaks and improvements to the DirEntry docs here: 
http://bugs.python.org/issue26248 -- the idea is to fix the issues you 
mentioned to clarify when system calls are required with symlinks, mentioning 
that the results are cached separately for follow_symlinks True and False, etc.

[issue26248] Improve scandir DirEntry docs, especially re symlinks and caching

[STINNER Victor]

STINNER Victor added the comment:

The change looks good to me. I pushed it to 3.5 & 3.6. It will be online in a 
few hours at:
https://docs.python.org/dev/library/os.html#os.DirEntry

I keep the issue open a few days to see if some others have other suggestions.

[issue26249] Change PyMem_Malloc to use PyObject_Malloc allocator?

[STINNER Victor]

New submission from STINNER Victor:

The issue #23601 showed speedup for the dict type by replacing PyMem_Malloc() 
with PyObject_Malloc() in dictobject.c.

When I worked on the PEP 445, it was discussed to use the Python fast memory 
allocator for small memory allocations (<= 512 bytes), but I think that nobody 
tested on benchmark.

So I open an issue to discuss that.

By the way, we should also benchmark the Windows memory allocator which limits 
fragmentations. Maybe we can skip the Python small memory allocator on recent 
version of Windows?

Attached patch implements the change. The main question is the speedup on 
various kinds of memory allocations (need a benchmark) :-)

I will try to run benchmarks.

--

If the patch slows down Python, maybe we can investigate if some Python types 
(like dict) mostly uses "small" memory blocks (<= 512 bytes).

[issue26221] asynco run_in_executor swallows StopIteration

[Ian Kelly]

Ian Kelly added the comment:

The place I'd expect to find it is in 
https://docs.python.org/3/library/asyncio-task.html#coroutines, in the list of 
"things a coroutine can do". The first two bullets in the list say that any 
exceptions raised will be propagated. Maybe there should be a note after the 
bullet list to the effect that "StopIteration carries special meaning to 
coroutines and will not be propagated if raised by an awaited coroutine or 
future."

[issue22121] IDLE should start with HOME as the initial working directory

[Jeff Allen]

Jeff Allen added the comment:

I'm also interested in a smooth experience for beginners.

I have a factual observation with respect to Terry's comment:
'''Windows icons have a Shortcut tab with a Start-in field.  We should like to 
put %USERPROFILE% there, but this does not work -- msg253393.'''
... I note that several menu shortcuts have "Start in" set to 
%HOMEDRIVE%%HOMEPATH%. Examples are notepad, Internet Explorer and the command 
prompt. (This is on Win7x64.) What we want seems to be a normal thing to do, 
and achieved by some, but perhaps by a post installation script.

Alternatively, once a .py file exists where you want to work, right-click "Edit 
with IDLE" provides the CWD we'd like best. Idea: add a New >> Python File 
context menu item. Encourage users to create a new file that way, then open it, 
and everything from there is smooth. (New issue if liked.)

[issue26119] Windows Installer can sometimes silently fail pip stage

[Paul Hammant]

Paul Hammant added the comment:

Chronalog for today, below. Status - can reproduce at will, can't produce 
%TEMP% files was for - there aren't any.

0. I deleted all Python prefixed files from %TEMP%

1. I uninstalled Python 3.4 via it's windows installer. It progressed to 
completion. I noted after that there was still a C:\python34 directory with 
some remaining items in it. There was also still a PYTHONHOME environmental 
variable.

2. I installed Python 2.7 via it's canonical windows installer, and (as per 
this bug filing) it barfs, and then (with a couple of clicks from me) proceeds 
to undo the installation.

3. I've checked the %TEMP% folder. There's nothing in there with a matching 
timestamp, nor anything at all prefixed with 'Python'

4. If I redo #2 and explicitly de-select pip, the installation completes as 
expected.

5. If I uninstall (via the installer) and attempt to reinstall WITH pip, it 
barfs (as per this bug filing)

6. If I delete the PYTHONHOME env-var and attempt, it works.

Conclusion - Pip aspect of WindowsInstaller gets caught out on presence of 
erroneous PYTHONHOME. It does so for Python 2.7.x replaceing and Python 3.5.x 
or the opposite order.

[issue26251] Use "Low-fragmentation Heap" memory allocator on Windows

Python has a memory allocator optimized for allocations <= 512 bytes: 
PyObject_Malloc(). It was discussed to replace it by the native

I'm not aware of anyone who tried that. I would nice to try, especially to run 
benchmarks.

See also the issue #26249: "Change PyMem_Malloc to use PyObject_Malloc 
allocator?".

[issue17446] doctest test finder doesnt find line numbers of properties

[Michael Cuthbert]

Michael Cuthbert added the comment:

this is my first contribution to Python core so I really have no idea how to do 
this, but I have found a solution (works in Py3.4, 2.7):

in doctest.py after line 1087 ("lineno = getattr(obj, 'co_firstlineno', 
None)-1")  add these lines:

if lineno is None and isinstance(obj, property) and \
obj.fget is not None:
obj = obj.fget.__code__
lineno = getattr(obj, 'co_firstlineno', None) 
# no need for -1 because of decorator. 

I can try to make a patch file for this, but just want to be sure I'm on the 
right track for contributing first.  I know how to do a Git pull, but not 
hg/patch.

(p.s., I think the current code "lineno = getattr(obj, 'co_firstlineno', 
None)-1" has an error; if the getattr does not find 'co_firstlineno', it will 
return None and then subtract 1 from None which is a TypeError).

[issue26119] Windows Installer can sometimes silently fail pip stage

[Steve Dower]

Steve Dower added the comment:

It's not clear which version of Python you are having trouble with, but it 
apparently isn't 3.5.

The PYTHONHOME variable is never set or modified by our installers, but some 
earlier versions may be affected by it. We recommend never setting environment 
variables globally - only in the command prompt when you're about to use them.

If the issue is with 3.4, it won't get fixed. Future releases of that branch 
will not come with builds for Windows.

Once you've cleared the stray variable, please let us know if you have trouble 
with 2.7 and/or 3.5.

[issue24266] raw_input + readline: Ctrl+C during search breaks readline

[Thomas Caswell]

Thomas Caswell added the comment:

I do not think that readline-cancel.patch is sufficient. The clean up function 
that readline uses internally 
(http://git.savannah.gnu.org/cgit/readline.git/tree/isearch.c#n720 ) also 
cleans up the context that used by isearch.

The functions to cleanup the context (and a pointer to the context) are exposed 
on `rlprivate.h` so python _can_ get at them to support old versions of rl. 
Once started down that path for isearch mode, might as well vendor all of 
rl_callback_sigcleanup() which will end up being 50-100 LoC (some of the helper 
functions will also need to be vendored).

[issue26253] tarfile in stream mode always set zlib compression level to 9

[Patrik Dufresne]

New submission from Patrik Dufresne:

When using tarfile.open(mode='w|gz'), the compression level is hard-coded to 9. 
Seed _Stream._init_write_gz():
self.zlib.compressobj(9,

1. In regards to zlib, I would start by replacing the value of 9 by 
zlib.Z_DEFAULT_COMPRESSION. This is the default value and zipfile is using it. 
Why using something different.

2. Then, I would also love to control the compression level when calling 
tarfile.open()

[issue26254] ssl server doesn't work with ECC certificates

[Evgeny Kapun]

New submission from Evgeny Kapun:

I tried to use ssl module to create a server with a certificate that uses an 
ECC key. However, this didn't work. Here is how to reproduce this:

First, generate a key and a certificate:

$ openssl req -newkey ec -pkeyopt ec_paramgen_curve:prime256v1 -x509 
-keyout key.pem -out cert.pem
(type some passphrase, then just press Enter in response to the questions 
that it asks)

Then run this Python program:

from socket import socket
from ssl import wrap_socket
s = socket()
s.bind(('localhost', 12345))
s.listen()
wrap_socket(s.accept()[0], 'key.pem', 'cert.pem', True)

This program will wait for a connection, so try to connect:

$ openssl s_client -connect localhost:12345

The program will ask for a passphrase, so type it. After that, you will get an 
exception:

Traceback (most recent call last):
  File "test.py", line 6, in 
wrap_socket(s.accept()[0], 'key.pem', 'cert.pem', True)
  File "/usr/lib/python3.5/ssl.py", line 1064, in wrap_socket
ciphers=ciphers)
  File "/usr/lib/python3.5/ssl.py", line 747, in __init__
self.do_handshake()
  File "/usr/lib/python3.5/ssl.py", line 983, in do_handshake
self._sslobj.do_handshake()
  File "/usr/lib/python3.5/ssl.py", line 628, in do_handshake
self._sslobj.do_handshake()
ssl.SSLError: [SSL: NO_SHARED_CIPHER] no shared cipher (_ssl.c:645)

If the certificate uses RSA key, it works. With ECC, I had no luck. I tried 
creating a context explicitly and using set_ciphers method to enable more 
ciphers. While it appears to support ECDSA ciphersuites, it can't use them for 
some reason.

[issue26238] httplib use wrong hostname in https request with SNI support

[Martin Panter]

Martin Panter added the comment:

The code fragment you posted looks like it is from HTTPSConnection.connect() 
. But 
_get_hostport() is already called to set self.host in __init__(), and to set 
self._tunnel_host in set_tunnel(). So I do not understand what you are 
proposing. Can you provide a patch?

Failing that, can you give a demonstration where the SNI and “request 
ServerName” (is this the Host header field?) mismatch?

The only potential bug I can see is if you specify the host by IP address, the 
IP address is sent as the SNI, when RFC 6066 seems to say a literal IP address 
is not permitted.

Client (run in Python 2.7.11):
>>> conn = HTTPSConnection("127.0.0.1:44300", 
>>> context=ssl._create_unverified_context())
>>> conn.request("GET", "/")

Server (run in Python 3.6):
>>> server = socket()
>>> server.bind(("localhost", 44300))
>>> server.listen()
>>> context = SSLContext(PROTOCOL_SSLv23)
>>> @context.set_servername_callback
... def callback(conn, name, context):
... print(f"Requested server name {name!r}")
... context = SSLContext(PROTOCOL_SSLv23)
... context.load_cert_chain("Lib/test/keycert.pem")
... conn.context = context
... 
>>> [conn, _] = server.accept()
>>> wrapped = context.wrap_socket(conn, server_side=True)
Requested server name '127.0.0.1'

My understanding is the client shouldn’t use SNI here, in which case the server 
name would be None.

[issue26253] tarfile in stream mode always set zlib compression level to 9

[Martin Panter]

Martin Panter added the comment:

It looks like the default has been hard-coded to 9 ever since tarfile was added 
to Python. The gzip module is also hard-coded to 9 since it was added. If 
tarfile is changed, maybe gzip should too.

Why would you want to use zlib’s default (apparently 6)? Memory usage or speed 
perhaps? If we do change the default, maybe it is best to only do it in 3.6. I 
don’t see it as a bug fix, and there is a chance it could break someone’s code.

To be able to control the compression level, perhaps you can already do it by 
wrapping the tar stream with GzipFile (untested):

gz_writer = GzipFile(fileobj=raw_writer, mode="wb", compresslevel=...)
tar_writer = tarfile.open(fileobj=gz_writer, mode="w|")
tar_writer.addfile(...)
tar_writer.close()
gz_writer.close()

If the default is changed, it certainly makes sense to add an easy compression 
level parameter, to be able to restore the old behaviour.

[issue26245] AttributeError (GL_READ_WRITE) when importing OpenGL.GL

[Berker Peksag]

Berker Peksag added the comment:

Thanks for the report, Yoha. Your third example shows that this is either an 
error in PyOpenGL or there is something wrong in your PyOpenGL installation. 
Please report this to their issue tracker.

[issue26246] Code output toggle button uses removed jQuery method

[Liang Bo Wang]

New submission from Liang Bo Wang:

The code output toggle button (the `>>>` button on the top right) has been 
disappeared and not functional on the current online documentation (both 3.4+ 
and 2.7). 


For example, see any doc page that has interpreter outputs:

https://docs.python.org/3/tutorial/introduction.html#numbers
https://docs.python.org/3.5/tutorial/introduction.html#numbers
https://docs.python.org/3.4/tutorial/introduction.html#numbers
https://docs.python.org/2/tutorial/introduction.html#numbers


These toggle buttons are created dynamically using jQuery by the script at 
Doc/tools/static/copybutton.js. However, the method .toggle() it used for click 
event handling has been deprecated since jQuery 1.8 and removed since jQuery 
1.9.

https://api.jquery.com/toggle-event/


Current Python documentation ships with jQuery v1.11.1 and it has a new 
.toggle() method with totally different behavior, which controls animation and 
hide the element. Therefore those buttons are invisible and has no effect.

https://api.jquery.com/toggle/


To achieve the old behavior, one now needs to create this toggle event on one's 
own. The most popular way to store the toggle state is by jQuery's .data() data 
storage.

A patch is attached to make the button functional again.

[issue26245] AttributeError (GL_READ_WRITE) when importing OpenGL.GL

[Yoha]

New submission from Yoha:

Importing `OpenGL.GL` fails on Python 3.5:

```

>>> import OpenGL.GL

It seems to work fine in Python 3.4:

```

[GCC 5.3.1 20160101] on linux

>>> import OpenGL.GL
>>> 
```

Or by first importing `OpenGL.GLU`:

```

[GCC 5.3.1 20160101] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import OpenGL.GLU
>>> import OpenGL.GL
>>> 
```

[issue26247] Document Chrome/Chromium for python2.7

[Ismail s]

New submission from Ismail s:

The table of browser types in 
https://docs.python.org/2.7/library/webbrowser.html?highlight=webbrowser#webbrowser.register
 does not say that Google Chrome/Chromium is available on python2.7, even 
though it is (https://hg.python.org/cpython/file/2.7/Lib/webbrowser.py#l307).

Also, according to the docs for python.3.5 
(https://docs.python.org/3.5/library/webbrowser.html?highlight=webbrowser#webbrowser.register
 , just below the table), support for google chrome/chromium was added in 
python3.3, so maybe this was backported to python2.7 and the docs not updated?

[issue26248] Improve scandir DirEntry docs, especially re symlinks and caching

[Ben Hoyt]

New submission from Ben Hoyt:

Per Guido's comment about DirEntry documentation on Issue 26032, especially 
http://bugs.python.org/issue26032#msg257665, it'd be good to improve the docs 
of the scandir DirEntry methods with regard to symlinks and caching.

Attaching my stab at a documentation fix. Changes here are:

1) Clarify that the return values of is_dir()/is_file()/etc are cached 
separately for follow_symlinks True and False.
2) Be more specific about when the functions require a system call, and how it 
relates to caching and follow_symlinks.
3) DRY up common stuff between is_dir and is_file by saying "Caching, system 
calls made, and exceptions raised are as per is_dir" in is_file.
4) Tweak to the first paragraph of docs for is_dir/is_file to simplify: assume 
the follow_symlinks=True default, then note the follow_symlinks=False 
non-default case after.

I think they're all improvements, though I'm not sure about #3. Is it better to 
just repeat those couple of paragraphs verbatim?

I'm also not 100% sure about mentioning the DT_UNKNOWN thing. But you really 
can't get more specific about when system calls are required on Unix without 
mentioning it.
