The code that needs to be changed is in distutils, setuptools just calls into
it. I haven't checked flit but I expect it does the same.

I have yet another use case for the function implemented by this patch (i.e.
retrieving the cert chain actually sent by the server, regardless of whether
that gives a path to a trust anchor). I'm implementing a network forensics
tool, and one

Recent versions of the gzip command-line utility have an option `-n` which
causes it to omit the FNAME field of the gzip file header, and write out the
MTIME field as zero. Both of these properties are desirable when constructing
reproducible build

New submission from Zack Weinberg :
Reproducibility has so far been concerned primarily with binary packages, but
it's also desirable for source tarballs to be reproducible starting from a
version-control checkout. This is particularly important for Python, where
'setup.py sdist' can run
Zack Weinberg added the comment:
> To be clear: this issue is NOT a bug in Python
I don't think that's entirely true. I think CPython needs to be linked against
libgcc_s.so, so that this class of application bugs will no longer manifest as
interpreter crashes. I filed #37
New submission from Zack Weinberg :
There are several existing issues (e.g. #18748 and #35866) where at least part
of the problem is that GNU libc tried to dlopen() `libgcc_s.so` at a moment
when that's not safe, e.g. during thread or process shutdown. This converts a
recoverable error
Zack Weinberg added the comment:
I have observed this problem in a production application using Python 3.5 and
3.6 (system-packaged interpreters from Ubuntu) and I would like to mention that
this is an effective workaround:
```
import ctypes
libgcc_s = ctypes.CDLL("libgcc_s
Zack Weinberg added the comment:
Also, whether or not the current behavior is the intended behavior, I think
programmers would appreciate an explicit statement of whether or not it might
change in the future.

The documentation of the semantics of range expressions in regular expression
character classes is not precise enough. All it says is
Ranges of characters can be indicated by giving two characters and
separating them by a '-', for example [a-z

It looks to me as if NameAliases.txt is the better reference for the C0 and C1
controls. It matches the UnicodeData.txt field 10 names for most entries where
the field 1 name is "", but it has names for U+0080, U+0081, U+0084,
and U+0099, which hav
New submission from Zack Weinberg:
unicodedata.name() doesn't have name information for the C0 and C1 control
characters. To see this, run

New submission from Zack Weinberg:
Occasionally one encounters binary formats which do not stick to one byte order
throughout. For example, I have a C program that reads and writes arrays of
this struct:

> Obvious question: why not working on the asyncio support in this library?
The whole point of a transparent SOCKS module is that it provides a function
that's a *drop-in replacement* for socket.socket(). An asyncio-based SOCKS
module would have a complet
New submission from Zack Weinberg:
This is pretty esoteric, please bear with me. I'm attempting to enhance a
transparent-SOCKS module (https://github.com/Anorov/PySocks) to support
non-blocking connect(). This means, you should be able to do this:
socks.set_default_proxy(socks.SOCKS5
New submission from Zack Weinberg:
The `re` module documentation does not do a good job of explaining exactly what
`\w` matches. Quoting https://docs.python.org/3.5/library/re.html :
> \w
> For Unicode (str) patterns:
> Matches Unicode word characters; this includes most characters

Zack Weinberg added the comment:
FWIW, the actual behavior of \w matching "everything in Unicode general
categories L* and N*, plus U+005F (underscore)" is consistent across all
versions I can conveniently test (2.7, 3.4, 3.5).
In 2.7, there are four characters in general category
Zack Weinberg added the comment:
In terms of the formal grammar of the language, you are correct. However, the
position of the caret should be chosen based *not* on the formal grammar, but
on a heuristic estimation of what the most probable mistake actually is. In
both of the cases I listed
New submission from Zack Weinberg:
I tripped over a couple of SyntaxError cases where the diagnostic caret is
misplaced.
While x:

Zack Weinberg added the comment:
I think that it will be better not introduce a new argument, but reuse stdin.
Just allow io.BytesIO (or perhaps even any file object) be specified as stdin.
If we were designing from scratch I might agree, but we aren't. Principle of
least astonishment says
Zack Weinberg added the comment:
Note also that allowing `stdin=any filelike` in a clean fashion would require
rather more surgery than you suggest, because a filelike can produce an
infinite stream of data, and people would expect that to work when the
subprocess only reads a finite prefix
Zack Weinberg added the comment:
My position is:
* input= should be supported in check_output(), for consistency with
communicate().
* I like the idea of making stdin= support file-like objects which don't have a
fileno, in both communicate() and everything that calls it, but that does
Zack Weinberg added the comment:
??? communicate() has always had input= AFAIK.
