[issue19763] Make it easier to backport statistics to 2.7

[Christian Heimes]

Christian Heimes added the comment:

Python's stdlib contains other modules that contain code for older versions of 
Python. The platform module even contains lines like os.devnull was added in 
Python 2.4, so emulate it for earlier. asyncio has backward compatibility 
code, too. The only old syntax I'd like to add is the super() thing in the test 
module. They are just tests...

The modified imports and doc test adjustments like

- mean([1, 2, 3, 4, 4])
-2.8
+ mean([1, 2, 3, 4, 4]) == 2.8
+True

would greatly help, though.

[issue15798] subprocess.Popen() fails if 0, 1 or 2 descriptor is closed

[Gregory P. Smith]

Gregory P. Smith added the comment:

adding {0,1,2} to fds_to_keep (populated from pass_fds) is indeed an alternate 
approach.  A variant of an alternate patch doing that attached.

This actually simplifies code.  Is there anything this would hurt that i'm not 
seeing?

I suppose it adds minor overhead to the fork_exec() call by passing more in and 
lookups into the fds_to_keep list now that it will always contain at least 4 
values instead of the previous 1.  I doubt that is matters (I haven't measured 
anything).

Oh, except:

-data = [allocate_bytes(123) for count in range(1000)]
+[allocate_bytes(123) for count in range(1000)]

If you don't store the result, the memory is immediatly released.

[issue19734] venv and ensurepip are affected by pip environment variable settings

[Nick Coghlan]

Nick Coghlan added the comment:

Hmm, this may also indicate a bug in pip's require virtualenv handling.
Why isn't it detecting that sys.prefix and sys.base_prefix are different,
and hence it *is* running in a venv created virtual environment?

[issue19764] subprocess: use PROC_THREAD_ATTRIBUTE_HANDLE_LIST with STARTUPINFOEX on Windows Vista

[STINNER Victor]

New submission from STINNER Victor:

subprocess.Popen has a race condition on Windows with file descriptors: if two 
threads spawn subprocesses at the same time, unwanted file descriptors may be 
inherited, which lead to annoying issues like cannot delete a file because it 
is open by another process. For the issue #19575 for an example of such bug.

Since Windows Vista, a list of handle which should be inherited can be 
specified in CreateProcess() using PROC_THREAD_ATTRIBUTE_HANDLE_LIST with 
STARTUPINFOEX. It avoids the need to mark the handle temporarly inheritable.

For more information, see:
http://www.python.org/dev/peps/pep-0446/#only-inherit-some-handles-on-windows

[issue19509] No SSL match_hostname() in ftp, imap, nntp, pop, smtp modules

[Christian Heimes]

Christian Heimes added the comment:

The patch implements check_hostname in order to match SSL certs with the peer's 
hostname in ftp, imap, nntp, pop and smtp library. So far the patch needs more 
tests and doc updates.

I consider the new feature a security fix. Right now everybody with any valid 
TLS/SSL certificate can claim that its certificate is valid for 
'smtp.google.com'.

[issue19767] pathlib: iterfiles() and iterdirs()

[Jonas H.]

New submission from Jonas H.:

From my personal experience, listing all real files and all subdirectories in 
a directory is a very common use case.

Here's a patch that adds the `iterfiles()` and `iterdirs()` methods as a 
shortcut for `[f for f in p.iterdir() if f.is_dir/file()]` .

[issue19768] Not so correct error message when giving incorrect type to maxlen in deque

[Vajrasky Kok]

New submission from Vajrasky Kok:

 from collections import deque
 deque('abc', maxlen='a')
Traceback (most recent call last):
  File stdin, line 1, in module
TypeError: an integer is required

But it's a lie. You can give None to maxlen
 deque('abc', maxlen=None)
deque(['a', 'b', 'c'])

maxlen with None value means unlimited.

You can give boolean value too to maxlen.

 deque('abc', maxlen=True)
deque(['c'], maxlen=1)

But since we use boolean and integer interchangeably in Python, so this should 
not matter in this case.

So, after the patch:
 deque('abc', maxlen='a')
Traceback (most recent call last):
  File stdin, line 1, in module
ValueError: maxlen must be integer or None

Don't worry, I only overrode the TypeError one. So overflow error should be 
kept intact.

 deque('abc', maxlen=2**68)
Traceback (most recent call last):
  File stdin, line 1, in module
OverflowError: Python int too large to convert to C ssize_t

I did not override the negative integer error message, because I assume when 
people give negative integer, they are in the mindset of giving integer value 
to maxlen.

 deque('abc', maxlen=-3)
Traceback (most recent call last):
  File stdin, line 1, in module
ValueError: maxlen must be non-negative

[issue5639] Support TLS SNI extension in ssl module

[Dima Tisnek]

Dima Tisnek added the comment:

Is this really not going into Python2 series?

It's not a Python feature or a language feature, it's a matter of exporting 
OpenSSL feature.

Furthermore it's a matter of security, same as support for session tickets is a 
matter of performance.

SNI was first introduced in 2004, RFC in 2006, libcurl supported it from 2008, 
you had a patch since 2009 and still it's not in?

Are you guys intentionally trying to cripple Python2?

What do you think is likelier outcome, faster Python3 adoption or Python  
labelled insecure?

[issue19732] python fails to build when configured with --with-system-libmpdec

 2.4~rc1:

Hmm. configure.ac doesn't use any of the variables set by that macro, and this
appears to work:

./configure --host=arm CC=arm-linux-gnueabi-gcc-4.7

  - there are still symbols which exists only for 32/64 bit archs.
intended?
(arch=@64@)mpd_qsset_i64@Base 2.3

(arch=@64@)mpd_sset_i64@Base 2.3
(arch=@64@)mpd_sset_u64@Base 2.3

That's on purpose:  These are low level functions that are supposed to set
static decimals as fast as possible.  A static mpd_t has a guaranteed
minimum allocation of two words for the coefficient. The 32-bit version
needs three words for UINT64_MAX, so they aren't available.

[issue19744] ensurepip should refuse to install pip if SSL/TLS is not available

[Bill Winslow]

Bill Winslow added the comment:

I've stumbled upon what appears to be a related issue, but I'm not sure it 
deserves its own bug report.

I compiled 3.4 on my LMDE (so essentially Debian testing) system, and aside 
from not building tkinter, various compression modules, etc., all went well. I 
ran `make test` with no errors, including the success of test_venv. (There were 
many and various warnings about deprecated code and calling str() on bytes 
instances, but I'm pretty sure none of it is related).

I ran `sudo make altinstall` (to not nuke my current 3.3 from the repos), and 
to my surprise, it failed with the following error:

[issue19585] Frame annotation

[Walter Dörwald]

Walter Dörwald added the comment:

Here is a new version of the patch. The annotation is done on the code object 
instead of on the frame object. This avoids two problems: There is no runtime 
overhead, as the decorator returns the original function and no additional 
frames show up in the traceback. Since the variables are only known at runtime, 
the annotation is now a function that does the formatting of the annotation 
message and gets passed the frame object. With this there is no runtime 
overhead when no exception is raised and even if an exception is raise, but the 
traceback is never formatted.

[issue19763] Make it easier to backport statistics to 2.7

[R. David Murray]

R. David Murray added the comment:

This is a tricky one.  I can see the arguments either way, but it just feels 
wrong to have future imports in stdlib code.

I personally don't see anything wrong with the import and doctest changes, 
though.  Sure, someone may come along later and unknowingly break something for 
your backport, but it isn't likely and IMO it's no big deal if it happens, you 
can just fix it when your tests fail.  I also don't mind the super call change 
personally, but that is much more likely to get changed by someone later, since 
I'm sure other people find it uglier than I do :)

Platform kind of operates under its own rules.  I suppose asyncio does as well 
:)

[Nick Coghlan]

Nick Coghlan added the comment:

So, the last part of the error message is just runpy getting confused because 
attempting to import pip.__main__ threw ImportError (it should check the 
ImportError name (see issue 19771).

I'm not sure about the first part though - I'm not sure why the pip wheel would 
lose track of a submodule like that.

[issue19771] runpy should check ImportError.name before wrapping it

[Nick Coghlan]

New submission from Nick Coghlan:

Issue 19769 shows that if __main__ in a package throws ImportError, runpy will 
incorrectly report the package as not being directly executable (when it 
actually claims to be executable, it's just broken)

This can be fixed in 3.3+ by checking for an appropriate value in the name 
attribute of the caught exception, and only wrapping it if the failed lookup 
was for the __main__ submodule we're looking for.

The associated test can just use a __main__.py that deliberately raises 
ImportError.

[issue19494] urllib2.HTTPBasicAuthHandler (or urllib.request.HTTPBasicAuthHandler) doesn't work with GitHub API v3 and similar

[Matej Cepl]

Matej Cepl added the comment:

I am trying to work on fixing issue 19494 (HTTPBasicAuthHandler doesn't work 
with Github and other websites which require prior Authorization header in the 
first request).

I have created this testing script calling GitHub v3 API using new 
“authentication handlers” (they are subclasses of HTTPSHandler, not 
HTTPBasicAuthHandler) and hoped that when I manage to make this script working, 
I could rewrite it into patch against cpython code.

However, when I run this script I get this error (using 
python3-3.3.2-8.el7.x86_64)

matej@wycliff: $ python3 test_create_1.py

Could anybody suggest what I am doing wrong? I seem to have problem of working 
in between two superclasses (HTTPHandler and AbstractBasicAuthHandler). I guess 
I need to somehow include into opener original HTTPBasicAuthHandler (for error 
handlers). Any ideas how to do it?

[issue19744] ensurepip should refuse to install pip if SSL/TLS is not available

[Nick Coghlan]

Nick Coghlan added the comment:

If the ssl import is actually in a submodule, you may need to list additional 
subpackages in the fresh parameter.

If you're wondering why this isn't in the importlib API - it's because it can 
go wrong in an impressively large number of ways, and we don't have any hope of 
documenting it well enough to make it usable by anyone that either: a) couldn't 
write it themselves; or b) isn't getting coached by someone that could write it 
themselves.

But when you know what you're doing and the modules involved don't break 
horribly when treated this way, it's a very neat trick for testing purposes.

[issue19763] Make it easier to backport statistics to 2.7

[STINNER Victor]

STINNER Victor added the comment:

Python's stdlib contains other modules that contain code for older versions of 
Python. The platform module even contains lines like os.devnull was added in 
Python 2.4, so emulate it for earlier.

I never understood why the platform module should be backport compatible. Marc 
Andre Lemburg wrote that it is shipped externally. I don't understand the 
purpose of having a third party platform module since the module is part of the 
stdlib.

 sure, but this should work without explicitly setting CC.

I can't get it to work without passing CC even with config.guess and
config.sub.  If you want it to work, could you submit a patch?  I've
set up a temporary repo:

hg clone http://bytereef.org:8000/ mpdecimal

Also, do you by any chance know a better solution for ldconfig (I'm
calling it unconditionally during install)?  I vaguely remember
that ldconfig does something different on OpenBSD.

[issue19763] Make it easier to backport statistics to 2.7

[STINNER Victor]

STINNER Victor added the comment:

 I'd like to add most modifications to 3.4 to simplify backporting.

I would prefer to not touch Python 3.4 backport just to simplify backporting. 
For example, I don't expect from __future__ import division in new Python 3.4 
modules, but only on old modules.

If the Python 3.4 evolves, you can use tools like meld to compare your backport 
and the latest version, and merge manually new changes. Or read Mercurial 
history of the Python 3.4 module to get patches.

For example, I maintain the faulthandler like that. I manually merge changes 
when I fix an issue in the CPython version. The version on PyPI is different: 
it uses SIGALRM instead of a thread, use PyInt_xxx() functions on Python 2, etc.

Do we expect many changes in the statistics modules?

Doctests are not reliable. IMO it's better to use unittest with testcases. 
unittest is easier to maintain, work with Python 2 and 3, and usually provide 
more useful reports on error.

unittest has more features like functions to skip a test on a specific platform.

[issue19743] test_gdb failures

[Dave Malcolm]

Dave Malcolm added the comment:

FWIW, I feel that it's worth just expecting failures with an *optimized* build: 
with an optimizing compiler, there's likely to always be some program counter 
location where the debugger is going to get confused for some variables.  Given 
umpteen different compiler variants, debugger variants etc, this is never going 
to be perfect.

So IMHO we should run the test on a --pydebug build, but accept that there will 
be some failures when optimization is on.

[issue19063] Python 3.3.3 encodes emails containing non-ascii data as 7bit

[R. David Murray]

R. David Murray added the comment:

Updated patch for 3.3, and a new patch for 3.4.  In 3.4, set_payload raises an 
error if non-ascii-surrogateescape text is passed in as the argument (ie: there 
are non-ascii unicode characters in the string) and no charset is specified 
with which to encode them.  In an ideal world it would instead default to 
utf-8, but because there may exist code that passes in unicode and then encodes 
it later by calling set_charset, we can't go that route in 3.4.  In 3.5, after 
the few people who may be in that boat have fixed their code to include the 
charset on set_payload, we can in fact make it default to utf-8.

I had to fix a couple 3.4 test, one of which was no longer valid because I've 
now defined the previously undefined behavior of set_payload when passed 
unicode, and one of which was just wrong but I didn't notice because of this 
bug.

[issue19772] str serialization of Message object may mutate the payload and CTE.

[R. David Murray]

New submission from R. David Murray:

Currently the string generator will downcast 8bit body parts to 7bit by 
encoding them using a 7bit CTE.  This is good.  However, the way it does it is 
to modify the Message object accordingly.  This is not good.  Except for 
filling in required missing bits of data (such as MIME borders), serializing a 
Message should not mutate it.  (And, for the curious, I am the one who made 
this mistake when I wrote the code :)

[issue19537] Fix misalignment in fastsearch_memchr_1char

[Stefan Krah]

Stefan Krah added the comment:

 (gdb) p sizeof(PyASCIIObject)
 $1 = 22

If the only issue is that the size should be 24 instead of 22,
could we perhaps add an unused uint16_t to the struct just
for this architecture?

Python 2.6 is out of commission and will not receive update anymore. You have

The _hashlib and _ssl errors look like a broken installation of openssl.

[issue19679] smtpd.py (SMTPChannel): get rid of conn attribute

[R. David Murray]

R. David Murray added the comment:

Are you referring to implementing rfc 3463 and rfc 5248 insofar as they are 
applicable?  That seems useful.  I don't see anything in the RFC about the 'xab 
x.y.z text' form of the message, though.  Where is that documented?  IMO these 
messages should only be emitted if we got an ELHO...actually I would expect 
there to be an extension keyword associated with this, but I don't see one in 
the RFC.

The conn argument is a separate issue.  (And probably should not change for 
backward compatibility reasons.  Also, it doesn't have to be a socket, although 
it would indeed be unusual if it wasn't.)

[Walter Dörwald]

Walter Dörwald added the comment:

Do you have an example where code objects are shared? We could attach the 
annotation formatter to the function object, but unfortunately the function 
object is now accessible in the traceback.

Note the co_annotation is not the annotation string, rather it is a function 
that does the formatting of the annotation.

[issue19691] Weird wording in RuntimeError doc

[Antoine Pitrou]

Antoine Pitrou added the comment:

The mention was already there in 1994 (2ec96140a36b), under the following form:

+\begin{excdesc}{RuntimeError}
+  Raised when an error is detected that doesn't fall in any of the
+  other categories.  The associated value is a string indicating what
+  precisely went wrong.  (This exception is a relic from a previous
+  version of the interpreter; it is not used any more except by some
+  extension modules that haven't been converted to define their own
+  exceptions yet.)
+\end{excdesc}

It was changed slightly from being a relic to mostly a relic in 1997 
(238a8b6096e1):

 \begin{excdesc}{RuntimeError}
   Raised when an error is detected that doesn't fall in any of the
   other categories.  The associated value is a string indicating what
-  precisely went wrong.  (This exception is a relic from a previous
-  version of the interpreter; it is not used any more except by some
-  extension modules that haven't been converted to define their own
-  exceptions yet.)
+  precisely went wrong.  (This exception is mostly a relic from a
+  previous version of the interpreter; it is not used very much any
+  more.)

[issue19678] smtpd.py: channel should be passed to process_message

[R. David Murray]

R. David Murray added the comment:

I think this is reasonable.  A patch would be welcome.

You could use inspect.  When I had to do something similar I just did the call 
inside a try/except, caught TypeError and retried without the extra argument.  
See the __init__ of email.feedparser.FeedParser.  I don't know which approach 
is better; although, with the new signature support in 3.4 perhaps inspecting 
the signature is better.

Another approach would be to designate a new method name for the new signature, 
and use hasattr to decide which to call.  That's actually a bit more consistent 
with the way the SMTPChannel works.

[issue19655] Replace the ASDL parser carried with CPython

[Eric Snow]

Eric Snow added the comment:

The concern, as far as I understand it, is that any change might introduce 
regressions or even new bugs in the next beta.  Something like swapping out the 
parser generator implementation isn't a bug fix, but it isn't a new language 
(incl. stdlib) feature either.

I don't have a problem with the change.  Furthermore, it likely doesn't matter 
since there probably won't be any grammar changes during the beta that would 
trigger the tool.

[issue17204] argparser's subparsers.add_parser() should accept an ArgumentParser

[paul j3]

paul j3 added the comment:

http://stackoverflow.com/a/20167038/901925
is an example of using `_parser_class` to produce different behavior in the 
subparsers.

parser = ArgumentParser()
parser.add_argument('foo')
sp = parser.add_subparsers(dest='cmd')
sp._parser_class = SubParser # use different parser class for subparsers
spp1 = sp.add_parser('cmd1')
spp1.add_argument('-x')
spp1.add_argument('bar')
spp1.add_argument('vars',nargs='*')

In this case the SubParser class implements a `parse_intermixed_known_args` 
method that handles that `nargs='*'` argument.

http://bugs.python.org/issue14191

It shouldn't be hard to add `parser_class` as a documented optional argument to 
`add_subparsers`.

[issue19729] [regression] str.format sublevel format parsing broken in Python 3.3.3

[HCT]

HCT added the comment:

my projects are total broken by this, so my temporary solution is to down grade 
to 3.3.2

somehow we don't have any test to check this before releasing 3.3.3

[issue19739] Legit compiler warnings in new pickle code on 32-bit Windows

[Zachary Ware]

Zachary Ware added the comment:

The attached patch fixes the warnings and doesn't appear to break anything 
obvious.

The first 4 are fixed by reverting Alexandre's change from '#if SIZEOF_SIZE_T' 
to 'if (sizeof(size_t)'.

The last one is different from the original 5th warning, and is fixed using the 
same trick that has been used in Modules/audioop.c; that is, use '(-0x7fffL 
- 1)' rather than '-0x8000L', which MSVC can't seem to handle.

[issue19774] strptime incorrect for weekday '0' when using week number format

[Steve J Borba]

New submission from Steve J Borba:

OS: Windows 7 Professional (64-bit)
Hardware: Intel

datetime.strptime returns an incorrect value when calculating a date using a 
week number format, such as %Y-%W-%w (Year-Week-Weekday). The value returned 
for weekday '0' of a given week is consistently 7 days greater than it should 
be. The following code illustrates:

from datetime import datetime
for i in range(0,53):
if i == 0:
yr=input(Enter a valid year: )
print(Wk#\tBeginning of week\tEnd of week)
BegWk = datetime.strptime((yr + - + str(i) + -0),%Y-%W-%w)
EndWk = datetime.strptime((yr + - + str(i) + -6),%Y-%W-%w)
print(str(i) + \t + str(BegWk) + \t +str(EndWk))

Here is a clip (7 lines) of the output from the code above:
Enter a valid year: 2013
Wk# Beginning of week   End of week
0   2013-01-06 00:00:00 2013-01-05 00:00:00
1   2013-01-13 00:00:00 2013-01-12 00:00:00
2   2013-01-20 00:00:00 2013-01-19 00:00:00
3   2013-01-27 00:00:00 2013-01-26 00:00:00
4   2013-02-03 00:00:00 2013-02-02 00:00:00
5   2013-02-10 00:00:00 2013-02-09 00:00:00
6   2013-02-17 00:00:00 2013-02-16 00:00:00

The value returned for the first column of each week is exactly 7 days higher 
than the correct result.

[issue19679] smtpd.py (SMTPChannel): implement enhanced status codes

[Leslie P. Polzer]

Leslie P. Polzer added the comment:

I am indeed referring to the enhanced status codes proposed in RFC 3463. This 
would just entail adding information to the status codes, converting them from 
the format simple status code human-readable string to simple status 
code enhanced status code human-readable string.

In this it doesn't seem necessary to differentiate by HELO/EHLO; neither is it 
demanded by the standard nor does it result in an incompatible form of 
traditional HELO status messages. HELO clients should just interpret the first 
three digits and regard the rest as part of the human readable informal section.

[issue19763] Make it easier to backport statistics to 2.7

[Georg Brandl]

Georg Brandl added the comment:

As Victor says, I'm not keen on those examples in the stdlib that do this, I'd 
rather get rid of all of them.

And yes, doctests are only useful if they are written in the simplest possible 
way.  Otherwise unittest style tests should be preferred.
