[issue25577] os.path.dirname leave left quote and remove right one

[Zachary Ware]

Zachary Ware added the comment:

As far as os.path.dirname is concerned, you have a file named 'ciao.pdf"' in a 
directory called '"ciao/come/stai', which is what you're seeing. Since those 
are legal names, there's no way for os.path.dirname to know what you actually 
want. The solution is to handle the quotes yourself however you want.

[issue25558] Use static asserts in C code

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

> By the way, I don't know what happens if you pass a variable to 
> Py_BUILD_ASSERT_EXPR() rather than a constant.

If the compiler can't calculate it at compile time (e.g. int_var <= INT_MAX), 
your are out of luck.

> Maybe we could use __builtin_constant_p() on GCC?

Don't know if it will help.

[issue25577] os.path.dirname leave left quote and remove right one

[Raffaele Mancuso]

New submission from Raffaele Mancuso:

Python 3.4.3 (default, Jun 29 2015, 12:16:01) 
[GCC 5.1.1 20150618 (Red Hat 5.1.1-4)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> dir = "\"ciao/come/stai/ciao.pdf\""
>>> dir
'"ciao/come/stai/ciao.pdf"'
>>> os.path.dirname(dir)
'"ciao/come/stai'

As you can see, dirname has removed the right quote, but not the left one.
The correct behaviour should be
'ciao/come/stai' (no quotes)
OR
'"ciao/come/stai"' (both quotes)
but never
'"ciao/come/stai' (only one quote)

This breaks other bash tools

audioop uses double for addition of 32-bit samples and converting to stereo. On 
this platforms it uses only highest 25 bits (including sign) and clears lowest 
7 bit.

Other tests also expose the lost of precision.

[issue24999] Segfault in test_re.test_sre_character_class_literals() when Python is compiled by ICC

[Tim Peters]

Tim Peters added the comment:

If it were treating doubles as floats, you'd get a lot more failures than this.

Many of these look like clear cases of treating _denormal_ doubles as 0.0, 
though.  I have no experience with ICC, but a quick Google search suggests ICC 
flushes denormals to 0.0 by default, and the compiler flag "no-ftz" (no 
flush-to-zero) is needed to stop that; e.g., see

If that is the decision, `message_from_string` should raise an
exception if it gets a non-ASCII argument!

[issue25576] Remove “Content-Type: application/x-www-form-urlencoded; charset” advice

[Martin Panter]

New submission from Martin Panter:

I understand using a “charset” parameter with “Content-Type: 
application/x-www-form-urlencoded” is not standardized. Since Issue 11082, the 
documentation advises to use it, but I propose to remove this advice.

HTML 5 mentions setting a _charset_ parameter, and mentions decoding with a 
default of UTF-8 (not Latin-1!), but does not mention any Content-Type 
parameters.

There seems to be confusion about what encoding it actually represents. 
According to , Mozilla 
briefly set this “charset” parameter a long time ago, but it would have 
corresponded to the urlencode(encoding=...) argument. The Python documentation 
currently suggests calling data.encode("utf-8"), which is misleading, because 
the urlencode() output is already guaranteed to be ASCII text. Any non-ASCII 
characters and bytes will already be character-encoded and percent-encoded by 
urlencode(). So I also propose to change the examples to data.encode("ascii").

[issue892902] problem with pickling newstyle class instances

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Thank you for your review Alexandre.

In 3.x old tests test_recursive_set and test_recursive_frozenset now are 
implemented in test_recursive_set_and_inst and 
test_recursive_frozenset_and_inst. Instead new test_recursive_set now tests 
protocol 4 ability of pickling recursive sets itself.

It does not currently work, because the docstring logic looks for a string, not 
an expression. And an f-string is an expression.

It would require changing the compiler to evaluate the f-string expression.

[issue25582] Fixed memory leaks in test_ctypes

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

POINTER() saves its result in internal cache. test_pointer_type_name and 
test_pointer_type_str_name use large names and resulting types consume much 
memory. This can be one of the causes of tests failure on the AIX buildbot with 
very limited memory.

If run tests repeatedly, the cache grows and can consume all memory even on the 
machine with enough memory.

Proposed patch fixes leaks.

[issue25179] PEP 498 f-strings need to be documented

[Emanuel Barry]

Emanuel Barry added the comment:

I think f-strings should be valid as docstrings. I don't know the exact 
details, but I think it would be harder to prevent rather than allow them. It 
would be exactly the same as doing func.__doc__ = func.__doc__.format(foo=foo, 
bar=bar)

It probably wouldn't be useful in most cases, but I don't see why we should 
restrict the use of f-strings to non-docstrings (not counting users trying to 
do that and stumbling across this error).

[issue25179] PEP 498 f-strings need to be documented

[Eric V. Smith]

Eric V. Smith added the comment:

Since f-strings are not constant strings, they cannot be used as docstrings 
without some modifications to the compiler.

I'm not sure it's worth evaluating a docstring f-string at compile time to make 
them become docstrings: I can't think of a use case where this would be 
worthwhile. But maybe I'm not thinking hard enough.

[issue25179] PEP 498 f-strings need to be documented

[Emanuel Barry]

Emanuel Barry added the comment:

I was under the impression that they would work without any additional work (as 
they'd have access to the outer scope). Of course, trying to access a local 
variable would be an error as it's not yet defined.

My point is more that we shouldn't have to account for such a small case - if 
they can be used, then let them be used, and if they can't, then don't (unless 
the modification is straightforward, which it might not be).

[issue25572] _ssl doesn't build on OSX 10.11

[Ronald Oussoren]

Ronald Oussoren added the comment:

If I read the issue correctly the OSX 10.11 SDK doesn't include OpenSSL 
headers. 

There's not a lot we can do about that beyond documenting this in the build 
instructions. 

It might be interesting to look into using Apple's crypto APIs instead of 
OpenSSL but that is a significant amount of work with limited pay-off (and a 
risk of introducing subtle differences between the OS X port and other ports)

[issue25345] Unable to install Python 3.5 on Windows 10

[Steve Dower]

Steve Dower added the comment:

It sounds like something went wrong during a previous installation (probably 
not Python 3.5) and your system is stuck in an "installing" state (hence system 
restore being disabled and the install mutex being held).

Those two logs are a month apart but the error remains. I assume you've 
installed Windows updates and rebooted during that time? That should have 
cleared up the state, but maybe you haven't been getting updates either?

why do you close it ?

def is not a keyword and it's a problem, how do you define a function is def is

async is not a keyword but if you used it before 'def', async will become a 
keyword.


have you checked the output from the tokenizer ? in the output, def is a NAME 
and not DEF.

[issue25579] def is not a keyword with tokenize.py

[SilentGhost]

SilentGhost added the comment:

Perhaps, my example wasn't as self-explanatory as I hoped. def is not DEF in 
the token list, because there isn't such a token DEF, as there isn't a token 
PASS or a token for any other keyword. The fact that there is an ASYNC and 
AWAIT tokens is something completely different and is not related to keywords 
as such. The link I provided lists all the tokens in the token module.

[issue24805] Python installer having problem in installing Python for all users in Windows

[Steve Dower]

Steve Dower added the comment:

I use /i, ADDLOCAL=ALL and ALLUSERS=1 with success all the time (/a does not do 
a real install - avoid it unless you know you'll be deploying the reduced size 
MSI to the rest of your network, and *especially* avoid it if you don't know 
why you'd want to do that).

The quotes are not necessary and neither is MSIINSTALLPERUSER. I generally use 
/quiet or /passive rather than /qb, so that may be part of the issue.

Also, your log output indicates that it was already installed when you ran that 
installation. Without the existing install it should be fine, but there's no 
way to change from a per-user install to a per-machine install with the 3.4 
installer. (The 3.5 installer, except for one bug that's probably not fixable 
before 3.5.2, should let a user install per-user and then per-machine if they 
want.)

Although I didn't read through the whole thing, the mozilla bug discussion

registered?

Tim: any idea why would this only show up on Windows?  Also, if you want a copy

[issue25581] Python -U raises error during site import

[R. David Murray]

R. David Murray added the comment:

Interesting, I didn't even know (remember?) about the -U flag, and it isn't 
documented.  I guess we don't test it, and I suppose that it is effectively 
deprecated.  (So others who don't remember don't need to repeat my research: it 
turns all string literals into unicode literals, which function was added as an 
experimental tool by Marc Andre in 2000.  I believe it was later superseded by 
'from __future__ import unicode_literals', but I didn't research that part.)

This works fine on linux, and the traceback looks like it involves some 
windows-specific code. 

I'm not sure if this is worth bothering to fix.

So, you write a string literal without a 'u' (or 'b') prefix, and there's no 
'from __future__ import unicode_literals' in the module, so you expect it to be 
a bytestring, but it's not, it's a Unicode string.

I'm not surprised that something breaks!

[issue25572] _ssl doesn't build on OSX 10.11

[Ned Deily]

Ned Deily added the comment:

"My understanding is that when we build an osx release, we bundle openssl."

Well, no, we don't exactly do that today.  We have recently been doing that for 
the 10.5 installer because the 10.5 system version of OpenSSL is so old as to 
be unusable for PyPI downloads (and pretty much everything else).  But the much 
more commonly used 10.6+ installer dynamically links with the latest (but 
deprecated) system OpenSSL libs shipped with OS X, libs that are old but usable 
and still receiving Apple security fixes on current systems.  The main reason 
for doing that is that this solution uses the Apple-provided system and user 
keychains for certificate management.  There are other drawbacks, though, and 
we have an open issue to deal with that.  (The python.org Pythons are not 
affected by the lack of headers since the libs are still shipped in OS X 
10.11.)  What I think this issue should address is making it easier to build 
Python on 10.11 (and earlier systems) with newer versions of OpenSSL.  It 
should be easier to use OpenSSL libs supplied by popular third-party distri
 butors like Homebrew and MacPorts.  Without having thought through all the 
details, I'm thinking it might be best to provide a configure-time check and 
option, possibly with standard options for the system,  Homebrew (default 
path), MacPorts (default path), and user-built SSL headers/libs.  It would also 
be good to provide something which will build the handful of important missing 
and/or newer third-party libs needed on OS X by the interpreter and standard 
library, like SSL libs, liblzma, and Tk.  But that's a separate issue.

[issue25545] email parsing docs: clarify that only ASCII strings are supported

[R. David Murray]

R. David Murray added the comment:

Issuing a warning is an interesting idea.  Basically, deprecate using a 
non-ASCII string with message_from_string etc formally by issuing a deprecation 
warning as well as the doc note.

[issue21935] Implement AUTH command in smtpd.

[R. David Murray]

R. David Murray added the comment:

I used some of this code in writing tests for the auth_login failure in issue 
25446 (thanks, Milan, you saved me a bunch of work :)

Now that we have asyncio and asynchat is deprecated, we've decided that the 
only real purpose of smtpd going forward is the smtplib tests.  Any other smtpd 
use should be converted to aiosmtpd instead.  Perhaps that library will 
eventually make its way into the stdlib and test_smtplib can use it as well.

So, I'm going to close this issue, but we may want to consider if and how auth 
fits into aiosmtpd (maybe as part of a 'testing server').

[issue25581] Python -U raises error during site import

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

What is worse, you write a string literal with a 'b' prefix, and you get a 
Unicode string.

>>> b''
u''

I tried to use Python with -U (it could be good way to test compatibility with 
Python 3), but it is totally broken, and there is no hope to fix it.

[issue25581] Python -U raises error during site import

[R. David Murray]

R. David Murray added the comment:

Well, in this case *he* didn't write the string, it is embedded somewhere in 
the stdlib.  'python -U' gets you to the python prompt on unix, but apparently 
not on windows.

But this isn't a feature we support any more, so I'm closing this as won't fix.

[issue25446] smtplib.py AUTH LOGIN code messed up sending login and password data since 3.5

[R. David Murray]

R. David Murray added the comment:

Fixed.  I figured it was better not to wait for a review in this case...the fix 
is straightforward, but writing the test took quite a bit of work.  The auth 
tests in smtplib are now much more robust, thanks in large part to Milan's code 
in issue 21935.
