Ah, sorry. Then it LGTM.

Do you have a microbenchmark that exposes a maximal effect of this change?

[issue29066] PIP doesn't honor --trusted-host or --cert options

[Utku Gultopu]

New submission from Utku Gultopu:

Steps to Reproduce
==
1. Install Python 3.6.0 on macOS Sierra, using the macOS binary installer from 
python.org.
2. Don't install any SSL certificates.
3. Run `pip install -U channels`. It will fail.
4. Run `pip install -U --trusted-host pypi.python.org channels`. It will fail 
too.
5. Run `pip --cert ~/cacert.pem install -U channels` (where `cacert.pem` is 
[this](https://curl.haxx.se/ca/cacert.pem).) It will fail too.

Expected Results

Command at number 3 to fail, commands at number 4 and 5 to succeed.

Actual Results
==
Commands at number 3, 4 and 5 fail.

Version Info

Python 3.6.0 (v3.6.0:41df79263a11, Dec 22 2016, 17:23:13) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin

macOS Sierra 10.12

pip 9.0.1 from 
/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages 
(python 3.6)

Explanation
===
I installed Python 3.6.0 on macOS Sierra, using the macOS binary installer from 
python.org.

Initially, I didn't install the necessary certificates by running the script 
/Applications/Python 3.6/Install Certificates.command.

When I wanted to install a module where PIP establishes an SSL connection 
during installation, I got an SSL: CERTIFICATE_VERIFY_FAILED error, as expected.

Command at step 3:

[issue29065] SSL module problem on Python 3.6.0 and macOS Sierra

[Ned Deily]

Ned Deily added the comment:

I've also added a note to the release downloads "Notes on this release" section:

"macOS users: If you are using the Python 3.6 from the python.org binary 
installer linked on this page, please carefully read the Important Information 
displayed during installation; this information is also available after 
installation by clicking on /Applications/Python 3.6/ReadMe.rtf. There is 
important information there about changes in the 3.6.0 installer-supplied 
Python, particularly with regard to SSL certificate validation."

[issue29065] SSL module problem on Python 3.6.0 and macOS Sierra

[Ned Deily]

Ned Deily added the comment:

>From the output you supplied, you appear to be using Python 3.6.0 from the 
>python.org macOS binary installer.  Please read the ReadMe.rtf file for the 
>installer which should have been displayed when you installed Python 3.6; a 
>copy of it is also installed in /Applications/Python 3.6.  You can read it by 
>double-clicking on the icon in the Finder or by entering the following shell 
>command:

open "/Applications/Python 3.6/ReadMe.rtf"

In it, the section on "Certificate verification and OpenSSL" notes that, as of 
the 3.6.0 installer, the Python supplied no longer links with the deprecated 
Apple-supplied system OpenSSL libraries but rather supplies a private copy of 
OpenSSL 1.0.2 which does not automatically access the system default root 
certificates.  "For 3.6.0, a sample command script is included in 
/Applications/Python 3.6 to install a curated bundle of default root 
certificates from the third-party certifi package 
(https://pypi.python.org/pypi/certifi).  If you choose to use certifi, you 
should consider subscribing to the project's email update service to be 
notified when the certificate bundle is updated."  You can run the command 
script by double-clicking on it or by entering the shell command:

open "/Applications/Python 3.6/Install Certificates.command"

If necessary, you can adapt the script for other options rather than using the 
certifi-supplied bundle.  For later releases, other standard options will 
likely be provided.

I don't understand your comment that using the system openssl command doesn't 
work, e.g. "openssl s_client -connect www.python.org:443".  The output you 
supply appears to show it working as expected.  But, in any case, that's not 
relevant to the Python 3.6 usage as different OpenSSL versions and libraries 
are being used.

Also note that this description only applies to the Python 3.6 supplied by the 
python.org macOS installer.  mscOS Pythons supplied by third-party distributors 
likely link with each distributor's version of OpenSSL and follow their root 
certificate policies.

[issue29059] Windows: Python not using ANSI compatible console

[Joseph Hackman]

Joseph Hackman added the comment:

The flag is application specific. I.e. a python program that writes to console  
using ansi codes, when used on windows, will just display the codes. If the 
Output is redireced to file and then the file is printed to console using a 
console tool, the colors will show instead.

[issue25591] refactor imaplib tests

[R. David Murray]

R. David Murray added the comment:

Committed.  FYI, I did have to make a few tweaks.  There were several lines 
longer than 80 characters still that I wrapped.  The tests failed with -W 
error:BytesWarning, something I normally run the tests with.  That required a 
fix to the library (a decode on the error message...if anyone is depending on 
the error message being bytes instead of string I'm sorry, but I doubt anyone 
is.  And finally, committing to 3.6 required adding the 'r' prefix to some of 
the tests regexes to eliminate the invalid escape warnings.

Thanks for your patience and persistence, Maciej.

[issue29059] Windows: Python not using ANSI compatible console

[INADA Naoki]

INADA Naoki added the comment:

Is it a global state, or application specific state?
In other words, if Python enables VT100, doesn't it remain after os._exit(1)?

If it is global state of console, why Python should change it?
Shouldn't user who want to use VT100 enable it before starting Python?

[issue29065] SSL module problem on Python 3.6.0 and macOS Sierra

It seems like ssl module is not working for me:

[issue29060] Changing the installation location still adds AppData filepaths that do not exist to the path variable on Windows 10

You're right. It was the launcher I was viewing. On the first page, I
unchecked installing the launcher for all users. Thanks for pointing out
that distinction.

Happy holidays.

[issue23903] Generate PC/python3.def by scraping headers

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Here is a shell script that uses the C preprocessor and other Unix tools to 
generate PC/python3.def. It doesn't add PyAST_* and PyNode_* functions and 
doesn't remove PyArg_VaParse* functions. But it still removes some names that 
are no longer used in public interface, but should be kept in the stable ABI 
for compatibility. E.g. PyCFunction_New (now it is a macro expanded to 
PyCFunction_NewEx) or _PyTrash_deposit_object (invoked by the macros before 
3.2.4). It seems to me that this is unavoidable, and the resulting file must be 
manually edited.

[issue29048] Coverage influence tests, make some of them fail

[Patrik Iselind]

Patrik Iselind added the comment:

OK, for now. Let's disregard my idea that stderr is swallowed. At some
point these test might have worked under coverage.

I was more thinking to bisect cpython. Perhaps i can find a revision that
works.

Ned Batchelder added the comment:

I don't believe this is coverage.py's fault, so I don't have an answer to your 
question.  There is no revision of coverage.py that *does* swallow stderr.  
Also, as you can see from the test output, it isn't swallowed, it's not being 
captured where it should be captured, but it is appearing on the terminal.  I 
see more than 60 uses of captured_stderr in the Python test suite. If 
coverage.py were swallowing stderr, I would expect dozens of test failures.  
The problem is more subtle.

If you want, you can bisect against any revision of coverage.py you like, 
perhaps the released 4.2?

[Patrik Iselind]

Patrik Iselind added the comment:

@nedbat, do you know of a revision where coverage doesn't influence the tests? 
If so, which one? Perhaps i can perform a bisect search to find when this went 
bad.

I'm testing the latest tip/head. So that's one part of the bisect.

[issue1116520] Prefix search is filesystem-centric

[Patrik Iselind]

Patrik Iselind added the comment:

What about the performance penalty for zipping stdlib? is it significant?

When would you like to zip stdlib? For embedded systems with limited disk
space?

I'd like to clarify that the file i just attached, no-stderr.diff, is in no way

[issue13886] readline-related test_builtin failure

[Xavier de Gaye]

Xavier de Gaye added the comment:

Thanks for waiting for a run of the patch on Android.
Indeed, test_input_tty_non_ascii fails with this patch on Android when LANG is 
not set and is ok when LANG=en_US.UTF-8. As you are suggesting, the test is ok 
when skipping the Readline half of the test. This may be done by adding 
'is_android' in the 'from test.support import ...' statement and updating the 
test with:

if readline and not is_android:
tests.append(True)

[issue29057] Compiler failure on Mac OS X - sys/random.h

[Pam McA'Nulty]

Pam McA'Nulty added the comment:

Good question.

It looks like there are 3 defines getting checked:
HAVE_SYS_RANDOM_H and either HAVE_GETRANDOM or HAVE_GETENTROPY

The previous issue seemed to be that you could have HAVE_GETRANDOM and/or 
HAVE_GETENTROPY be set, but still not have a sys/random.h, so a check was added 
for HAVE_SYS_RANDOM_H.  However, on macs, you can HAVE_SYS_RANDOM_H, but still 
not have either HAVE_GETRANDOM or HAVE_GETENTROPY.

This _probably_ implies that the sys/random.h that's present isn't conformant 
enough for the compiler settings and my mac's os and/or xcode.

[issue28997] test_readline.test_nonascii fails on Android

[Xavier de Gaye]

Xavier de Gaye added the comment:

With your patch Martin, test_nonascii is skipped on Android when LANG is not 
set and the issue is fixed.

> Just to clarify, is the problem that Python (correctly) assumes UTF-8 
> encoding on Android, but Readline does not unless you tweak the environment 
> variable?

Readline (correctly) uses the locale environment variables to set eight-bit 
mode (see function _rl_init_eightbit() in Readline nls.c) and when the LC_CTYPE 
category is C or POSIX, eight-bit characters are discarded on input and a bell 
character ('\x07') is echoed instead.

[issue29054] pty.py: pty.spawn hangs after client disconnect over nc (netcat)

[Cornelius Diekmann]

Cornelius Diekmann added the comment:

Thank you Martin very much. To resolve this issue, I decided to document the 
current behavior and add test cases for it. No change in behavior is 
introduced. This hopefully allows to close this issue. The test cases for the 
current behavior ensure that we can (at some point in the future) add some 
different behavior without breaking backwards compatibility.

Fixed: Observed behavior is now expected+documented behavior. Improved test 
cases.

Happy Holidays!

[issue29048] Coverage influence tests, make some of them fail

[Ned Batchelder]

Ned Batchelder added the comment:

I doubt very very much that coverage.py is stealing stderr.  Many many test 
suites would have this problem if that were true.  More likely is that somehow 
__del__ is not being invoked when you need it to be.

I tried running the tests under coverage also, and did not see this behavior. I 
don't have a build tree of the latest code, but I ran it on 3.6.0.  The tests 
passed both with and without coverage measurement (output below).  I would like 
to understand why you are seeing the results you are.

[issue29048] Coverage influence tests, make some of them fail

[Patrik Iselind]

Patrik Iselind added the comment:

I've been looking into test_exceptions, why it fails. The reason seems to be 
that when the tests are executed under coverage, then they get nothing on the 
line that says the following in test_unraisable().

```python
report = stderr.getvalue()
```
So coverage steal strerr in this case, and the test's thunder.

A way to get around this would be to not let the test rely in stderr but 
instead catch the exception and unfold it as a string for testing.

I fixed some Possible Loss of Data warnings. but only the ones for timemodule. 
There are still some others when building the 64 bit version however.

I added some comments that can be removed in another patch if desired otherwise 
it should look good for now for this module.

[issue29020] collapse_rfc2231_value has inconsistent unquoting

[bpoaugust]

bpoaugust added the comment:

Another case is get_filename.

The second call to unquote will only change the incoming parameter if the 
original value was enclosed in <> or "". This is not a common scenario, and was 
only discovered because a mailer used the form <<>> as a boundary marker 
(yes, this is invalid). So existing tests are unlikely to notice any difference.

Note that it is wrong to unquote more times than the original value has been 
quoted. So the only possible reason for keeping unquote in the function is if 
unquote has not already been called on a quoted value. (It is not possible to 
tell from the parameter whether or not it is currently quoted).

The two sample callers are get_boundary and get_filename.
Both pass the value already unquoted.

This method should be fixed to remove the unquote calls.
If there is a caller (is there one?) that does not unquote the value first, 
then that needs to be fixed as well.

[issue13886] readline-related test_builtin failure

[Martin Panter]

Martin Panter added the comment:

Hi Xavier, I was about to push input-readline.v2.patch, but I thought it might 
be good to check with you first if this causes problems with Android, based on 
my experience with Issue 28997. With the patch applied, 
test.test_builtin.PtyTests.test_input_tty_non_ascii() will call the input() 
function twice, with and without Readline enabled. It inputs non-ASCII data in 
into a pseudoterminal, and expects to see it in the function return value. 
Perhaps we may need to skip the Readline half of the test on Android.

[issue29061] secrets.randbelow(-1) hangs

[Brendan Donegan]

Brendan Donegan added the comment:

Ok, here it is. My first code patch in Python. 

Basically the existing code was depending on bit_length to DTRT and raise a 
ValueError, but negative numbers have a positive bit length. Then when it hits:

234 while r >= n:   
 
235 r = getrandbits(k)  

It just spins on that as r is always going to be greater than a negative number.

I tried not to be too clever so just put a guard early in the function. This 
has the added advantage of giving us a clearer error message.

[issue29062] Documentation link error

[Frank Millman]

New submission from Frank Millman:

If you call up online documentation for Python3.6, and select 
modules>h>hashlib, it takes you to 15.2. hashlib — BLAKE2 hash functions

It should take you to 15.1. hashlib — Secure hashes and message digests

Reproducible on Linux as well, I think I know where the issue is and will try

[issue28960] Small typo in Thread.join docs

[Martin Panter]

Martin Panter added the comment:

I agree the second patch is more correct. This undoes the change as it was 
introduced in revision c4cf1b886d6b and matches the Python 2 text.
