[issue30046] csv: Inconsistency re QUOTE_NONNUMERIC

[Xiang Zhang]

Xiang Zhang added the comment:

boolean is not quoted since in Python it's a subclass of int so True and False 
are numeric. This is also the case with numeric objects defining __int__ or 
__float__ but doesn't get a corresponding string representation.

Since QUOTE_NONNUMERIC will converts data to float when reading, I think we may 
force the converting even when writing so the inconsistency would disappear. Or 
document this limitation.

[issue30045] Bad parameter name in re.escape()

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

This looked not correct to me but if you say "pattern" seems right I'm closing 
this issue.

I'll update the parameter name in PR 1048.

[issue30060] Crash on Py_Finalize if Py_NoSiteFlag is used

[Stephen Kelly]

Stephen Kelly added the comment:

I found that if I build and run this code with Python 3, then I get a very 
different backtrace.

KernelBase.dll!7ff963466142()   Unknown
python36_d.dll!Py_FatalError(const char * msg) Line 1457C
python36_d.dll!PyEval_AcquireLock() Line 253C
mn.exe!main(int argc, char * * argv) Line 22C
[External Code] 

The failure is

 Py_FatalError("PyEval_AcquireLock: current thread state is NULL");

So, it is not clear to me what is incorrect about this code, but presumably I 
have done something incorrect here?

[issue30064] BaseSelectorEventLoop.sock_{recv, sendall}() don't remove their callbacks when canceled

[Evgeny Kapun]

New submission from Evgeny Kapun:

Code:

import asyncio as a
import socket as s

@a.coroutine
def coro():
s1, s2 = s.socketpair()
s1.setblocking(False)
s2.setblocking(False)
try:
yield from a.wait_for(loop.sock_recv(s2, 1), 1)
except a.TimeoutError:
pass
yield from loop.sock_sendall(s1, b'\x00')
yield
s1.close()
s2.close()

loop = a.get_event_loop()
loop.run_until_complete(coro())

[issue30065] Insufficient validation in _posixsubprocess.fork_exec()

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

_posixsubprocess.fork_exec() takes a sequence of file descriptors. It first 
validates it, and since the validation is passed uses it without checking for 
errors. But since __len__, __getitem__ and __int__ can execute user code and 
release GIL, errors can occur after the validation. This can cause a crash.

Proposed patch fixes this by the simplest way -- it restricts the type of a 
sequence to tuple and types of elements to int. Since _posixsubprocess is 
private module this shouldn't break third-party code.

Other issue with _posixsubprocess.fork_exec() was that it converts args to a 
tuple or a list and iterate it without checking if the size is changed.

[issue30060] Crash on Py_Finalize if Py_NoSiteFlag is used

[Stephen Kelly]

Stephen Kelly added the comment:

The issue

 http://bugs.python.org/issue17978 

has a quite similar backtrace and there is discussion in

 http://bugs.python.org/issue17703#msg241412

about changing the TRASHCAN macro to access the _PyThreadState_Current directly 
instead of calling PyThreadState_Get (which is fatal for a nullptr). The very 
next thing the TRASHCAN macro does is check if the thread state is nullptr in a 
non-fatal way. 

Is there a reason not to apply that patch?

We are not executing the doctests on Travis CI, but I executed them locally.  
That's why I realized there was a missed testcleanup.  The issue27200 wants to 
fix all doctests, and I actually completed the job, but three PRs are still 
opened, and I am waiting for review approval.  If you want to contribute to the 
reviews, look for 'bpo-27200' on the GitHub PRs.  I hope the doctest will be 
run on Travis as soon as possible.  Thanks, Marco

[issue30063] DeprecationWarning in json/encoder.py

[R. David Murray]

R. David Murray added the comment:

If a warning is causing iPython to hang, there is something seriously wrong 
with iPython.  A warning is just a message written to stderr, it doesn't affect 
the execution of the program.

The json module does not natively support datetime, so whatever is happening, 
it is being triggered by non-stdlib code (probably a json subclass in the vcs 
package you are working with).  I suggest you pursue this with the community 
that originated the vcs package.

[issue30065] Insufficient validation in _posixsubprocess.fork_exec()

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

It is hard to reproduce (especially the second issue) since in all cases in the 
stdlib a list passed to fork_exec() is just created by sorted() and doesn't 
have other references. But if someone is so insane that passes int-like objects 
with non-idempotent __int__ as file descriptors his can get a crash in debug 
build (or mystical bugs in release build). Added tests utilizes this, but this 
unlikely happens in real code.

I have found this issue during analyzing usages of PyObject_Size(), 
PySequence_Size() and PyMapping_Size() in issue30061.

[issue29636] Specifying indent in the json.tool command

[Daniel Himmelstein]

Daniel Himmelstein added the comment:

@bob.ippolito thanks for pointing to jq as a reference implementation. I 
updated the pull request (https://git.io/vS9o8) to implement all of the 
relevant options. Currently, the PR supports the following mutually exclusive 
arguments:

--indent
--no-indent
--tab
--compact

These additions took 16 new lines of code in tool.py and 41 new lines of tests. 
However, I am happy to refactor the tests to be less repetitive if we choose to 
go forward with these changes.

@serhiy.storchaka I took a maximalist approach with respect to adding 
indentation options to GH #345. Although I know not all of the options may get 
merged, I thought we might as well work backwards.

However, the more I think about it, I do think every option above is a unique 
and valuable addition. I think that even with the changes, json.tool remains a 
lightweight wrapper json.load + json.dump.

[issue30067] _osx_support.py: misplaced flags in re.sub()

[Jakub Wilk]

New submission from Jakub Wilk:

Lib/_osx_support.py contains the following line:

flags = re.sub(r'-arch\s+\w+\s', ' ', flags, re.ASCII)

But the 4th re.sub() argument is the maximum number of substitutions, so this 
is equivalent to:

flags = re.sub(r'-arch\s+\w+\s', ' ', flags, count=256)

It was probably meant to be:

flags = re.sub(r'-arch\s+\w+\s', ' ', flags, flags=re.ASCII)

[issue28765] _sre.compile(): be more strict on types of indexgroup and groupindex

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Since _sre.compile is not a public API, and is called only with exact 
list/dict/tuple types in the stdlib, I prefer to ignore possible differences 
between base classes and subclasses. This makes the code cleaner.

Searching on GitHub shows that usages of _sre.compile() in third-party code are 
not compatible with current _sre.compile() since all arguments now are 
mandatory and indexgroup must be a tuple, not None.

In _io._IOBase.readlines, it straightly uses PyIter_Next(self). But 
iter(_io._IOBase) does more work than just returning itself.

>>> f.close()
>>> f.readlines()
Traceback (most recent call last):
  File "", line 1, in 
ValueError: I/O operation on closed file.
>>> f.readlines(10)
