[issue12420] distutils tests fail if PATH is not defined

Skipping if the compiler isn't available is problematic, since that could

[issue21878] wsgi.simple_server's wsgi.input readline waits forever for non-multipart/form-data

[Robin Schoonover]

New submission from Robin Schoonover:

In the reference WSGI server in wsgiref.simple_server, wsgi.input's readline() 
hangs if the request body does not actually contain any
newlines.

Consider the following (slightly silly) example:

from wsgiref.simple_server import make_server

def app(environ, start_response):
result = environ['wsgi.input'].readline()

# not reached...
start_response("200 OK", [("Content-Type", "text/plain")])
return []

httpd = make_server('', 8000, app)
httpd.serve_forever()

And the following also silly request (the data kwarg makes it a
POST request):

from urllib.request import urlopen

req = urlopen("http://localhost:8000/";, data=b'some bytes')
print(req)

Normally this isn't a problem, as the reference server isn't intended
for production, and typically the only reason .readline() would be
used is with a request body formatted as multipart/form-data, which
uses ample newlines, including with the content boundaries.  However,
for other types of request bodies (such as application/x-www-form-urlencoded)
newlines often wouldn't appear, and using .readline() would wait forever for 
new input.

[Terry J. Reedy]

test_disutils still fails on both 2.7 and 3.4 installs. Since PATH is defined, 
that is not the issue here. I am tempted to unconditionally skip the test and

[issue13277] tzinfo subclasses information

[Alexander Belopolsky]

Alexander Belopolsky added the comment:

I would say this is a doc issue.  There are some tzinfo algorithms that depend 
on utcoffset(dt)-dst(dt) being invariant, but this is the part of datetime 
library that I have never fully understood.

What I do understand is that conversion from local time to UTC or another 
timezone is a hard and not always solvable problem (some local times are 
invalid and some are ambiguous).  (If some local government decides that 00:59 
should be followed by 02:00, one is hard pressed to figure out what 01:30 local 
time is in UTC.)

I think documentation should emphasize the fact that the standard library only 
supports fixed offset timezones.  It is up to the application programmer or a 
3rd party library to figure out which fixed offset is appropriate in which case.

[issue11754] Changed test to check calculated constants in test_string.py

[Terry J. Reedy]

Terry J. Reedy added the comment:

Three years later, I do understand 'circular'. Such cut-and-paste whitebox 
tests tend to simultaneously test too much -- the particular implementation(1) 
-- and too little -- the actual specification(2).

(1) The test would falsely fail if a string were reordered but still correct.
(2) The test would falsely pass is any of the existing strings were incorrect. 
Most of the strings have a specification other than the existing string and all 
can be tested in an order free manner. Hexdigits example:

import string
assert len(set(string.hexdigits)) == 22
for c in string.hexdigits:
assert '0' <= c <= '9' or 'a' <= c <= 'f' or 'A' <= c <= 'F'

I would be willing to push such a patch. I would also be willing to close this 
now.

Yes, this is the right fix. I'm closing this issue because it didn't get any

If you are interested to add -E in tests, please open a new issue with a patch.

empty_environment.diff is wrong, we should ignore PYTHON environement variables

[issue6692] asyncore kqueue support

[STINNER Victor]

STINNER Victor added the comment:

I read asyncore.patch: it is close to the selectors module, so it means 
duplicated efforts. I prefer to close this issuse since asyncore has been 
deprecated in favor of asyncio (and selectors).

Using the selectors module in asyncore would not be efficient because asyncore 
design requires to build a new selector for each poll, which is not efficient. 
asyncio only creates the selector once, and then use register/unregister. It's 
more efficient and scalable.

[STINNER Victor]

STINNER Victor added the comment:

I fixed the issue in Python 3.4 and 3.5, thanks for the report.

In Python 3.4+, it's safe to add a destructor (__del__ method): even if the 
object is part of a reference cycle, it will be destroyed. It's not the case in 
Python 2.7. I prefer to leave Python 2.7 unchanged to limit the risk of 
regression.

[issue12498] asyncore.dispatcher_with_send, disconnection problem + miss-conception

[STINNER Victor]

STINNER Victor added the comment:

"Actually the class asyncore.dispatcher_with_send do not handle properly 
disconnection. When the endpoint shutdown his sending part of the socket, but 
keep the socket open in reading, the current implementation of 
dispatcher_with_send will close the socket without sending pending data."

It looks like asyncore doesn't handle this use case.

To me, it doesn't look like a minor issue, but more a design issue. Fixing it 
requires to change the design of asyncore.

The asyncio module has a better design. It has a write_eof() method to close 
the write end without touching the read end. For example, for sockets, 
write_eof() calls sock.shutdown(socket.SHUT_WR). After write_eof(), the read 
continues in background as any other task. For the read end, the protocol has a 
eof_received() method to decide if the socket should close, or if it should be 
kept open for writing (but only for writing).

Moreover, the asyncore module has been deprecated in favor of the asyncio 
module.

I close this issue for all these reasons.

Sorry Xavier for your patches, but it's time to focus our efforts on a single 
module and asyncio has a much better design to handle such use cases.

[issue21877] External.bat and pcbuild of tkinter do not match.

[Zachary Ware]

Zachary Ware added the comment:

> compiles _tkinter is such a way that it looks for the two dlls 'everywhere' 
> (in pcbuild itself and 5-10 other, non-existent directories)

I think you're confusing the finding of the tcl/tk DLLs with the finding of 
init.tcl; the DLLs are searched for on PATH (as I understand it, just like any 
other DLL), while init.tcl is searched for in several places hard coded deep in 
bowels of Tcl (see #20035).

Python 3.5 (default branch) builds Tcl/Tk as part of the build solution rather 
than as part of external*.bat, and copies the DLLs to the output directory as 
part of the new system.  3.4 and 2.7 could be fixed to copy the DLLs as part of 
external*.bat, but will have issues similar to #21059 without some kind of fix 
like #20035 (which is currently only targetting default branch).

[issue21877] External.bat and pcbuild of tkinter do not match.

[Terry J. Reedy]

New submission from Terry J. Reedy:

dir/pydir/Tools/buildbot/external.bat downloads tcl/tk 8.y.z into dir/tcl-8.y.z 
and dir/tk-8.y.x and compiles them into dir/tcltk. Of critical importance are 
dir/tcltk/bin/tcl8yg.dll and dir/tcltk/bin/tk8yg.dll (where y is currently 5 or 
6.

dir/pydir/pcbuild/_tkinter.vcxprog compiles _tkinter is such a way that it 
looks for the two dlls 'everywhere' (in pcbuild itself and 5-10 other, 
non-existent directories) other than where they are.

The current manual fix, reported a year ago on core-mentorship list, is to copy 
the two .dlls into pcbuild. This should be done by external.bat.

A possible alternate fix would be to revise _tkinter.vcxproj so that _tkinter 
looks for the .dlls where they are. However, since multiple tcl/tk versions are 
compiled into /tcltk, this would break installations that use one 'dir' for 
multiple 'pydir's, as shown in the devguide. Currently, the .dlls must be 
copied into pcbuild before they get overwritten by another version.

[issue16133] asyncore.dispatcher.recv doesn't handle EAGAIN / EWOULDBLOCK

[STINNER Victor]

STINNER Victor added the comment:

Modifying recv() to return None doesn't look correct. I read it as: "you should 
always use recv() output, except if the result is None: in this case, do 
nothing". In Python, we use exceptions for that. BUT in fact, sock.recv() 
already raises an exception, so asyncore should not convert the exception to a 
magic value (None).

Modifying the behaviour of recv() in asyncore breaks the backward 
compatibility. Returning None makes it harder to write asyncore code working on 
Python 3.4 and 3.5 (if the change is done in Python 3.5).

I prefer EWOULDBLOCK.patch approach: document the issue in asyncore 
documentation and handle BlockingIOError in asynchat.

[issue9350] add remove_argument_group to argparse

[paul j3]

paul j3 added the comment:

I wonder if this patch is needed.

- there hasn't been discussion in 4 years

- In Steven's use case, a group without any arguments, the group does not show 
up.  A common example of an empty argument group, is a parser without any user 
defined arguments.  

p=argparse.ArgumentParser(prog='PROG')
p.print_help()

usage: PROG [-h]
optional arguments:
  -h, --help  show this help message and exit

The empty 'positional arguments' group is not displayed.

Removing a group that has arguments is more complicated (and error prone) since 
it requires removing those arguments as well.  There is a '_remove_action' 
method.  But as best I can tell it is only used by '_handle_conflict_resolve', 
a rarely used alternative conflict handler.

[issue21856] memoryview: test slick clamping

[Terry J. Reedy]

Terry J. Reedy added the comment:

Memoryview should definitely have the same slice tests as other sequence 
objects. Go ahead and check.

I believe slice clamping itself should now be done by slice.indices, not by 
each class.

S.indices(len) -> (start, stop, stride)

Assuming a sequence of length len, calculate the start and stop
indices, and the stride length of the extended slice described by
S. Out of bounds indices are clipped in a manner consistent with the
handling of normal slices.

It seems like this was written before it was normal for every slice to have a 
step (stride), defaulting to None/1. It definitely comes from 2.x, before 
__getslice__ was folded into __getitem__

I expect builtin 3.x sequence objects should all use something like the C 
equivalent of
def __getitem__(self, ob):
if type(ob) is slice:
   start, stop, stride = ob.indices(self.len)
   ...

[issue11273] asyncore creates selec (or poll) on every iteration

[STINNER Victor]

STINNER Victor added the comment:

"On the other hand, it appears to be quite difficult to integrate such a 
massive change into asyncore in a fully backward compatible manner. At least, 
it's not clear to me how to do this without breaking code relying on map's 
parameter and asyncore.socket_map."

Python 3.4 has now asyncio which creates a selector object which has 
register/unregister methods and so benefit of performances enhancements of 
epoll/kqueue/devpoll.

Since Giampaolo cares of backward compatibility of asyncore, and the fact that 
asyncore is now marked as deprecated ("This module exists for backwards 
compatibility only. For new code we recommend using asyncio."), I close this 
issue as wont fix ("wont fix" in asyncore, but it's already fixed in asyncio 
;-)).

[issue4899] doctest should support fixtures

[Terry J. Reedy]

Terry J. Reedy added the comment:

I am closing this for both the general reasons already given and the lack of a 
proposed api that could programmed, Hence there is no example code that would 
run and hence no specifics to approve. If someone wanted to pursue this, 
python-ideas would be a better place.

One of the general reasons given is that the example does not demonstrate a 
real need for the fixtures proposed. My take on the example code is this.

The input to TpedIterator is an iterable of lines. A list of lines will work as 
well an an open file. I would create a file of example lists and import the one 
needed for each docstring. For the example given.

def TpedIterator(lines):
'''Yield Marker for each line of lines.

>>> from biopython.sample_data import Tped
>>> for marker in TpedIterator(Tped):
...print(marker)
Marker rs1543, 2 individuals
Marker rs1929, 2 individuals
Marker rs10002472, 2 individuals

The preceding sentence "There are two new valid (semantic) forms for the raise

[issue21876] os.rename(src, dst) does nothing when src and dst files are hard-linked

Aaron Swan added the comment:

Although using the mv command *does* remove the src file on red hat linux, I 
can accept that the POSIX requirement that the source *must* be removed might 
not apply if source is the same as the destination file.

It would be nice if the behavior was consistent, but I think the POSIX 
requirements are somewhat up for interpretation in this case.

The documentation should probably be updated at the least.

Is this still an issue that needs addressing?  I can't try it myself as I use

[issue21876] os.rename(src, dst) does nothing when src and dst files are hard-linked

[Esa Peuha]

Esa Peuha added the comment:

This looks like a documentation bug. Functions in module os are usually just 
thin wrappers around the underlying OS functions, and POSIX states that doing 
nothing is the correct thing to do here. (It is arguably a bug in early Unix 
implementations that got mistakenly codified as part of POSIX, and it is 
certainly inconsistent with the POSIX requirement that the mv command *must* 
remove the source file in this case, but there is nothing Python can do about 
that.)

[issue21873] Tuple comparisons with NaNs are broken

[Raymond Hettinger]

Raymond Hettinger added the comment:

FWIW, the logic for tuple ordering is a bit weird due to rich comparisons.   
Each pair of elements is first checked for equality (__eq__).  Only if the 
equality comparison returns False does it call the relevant ordering operations 
(such as __lt__).   The docs get it right, "If not equal, the sequences are 
ordered the same as their first differing elements."

In short tuple ordering is different from scalar ordering because it always 
makes equality tests:
 
   a < b  calls   a.__lt__(b)

in contrast:

   (a, b) < (c, d)is more like:   if a != c:  return a < c ...

[issue10195] Memory allocation fault-injection?

[STINNER Victor]

STINNER Victor added the comment:

This feature is implemented in my external project:
https://bitbucket.org/haypo/pyfailmalloc

It was discussed to integrate it in Python 3.4, but I foscused my efforts on 
the PEP 445 (malloc API) and 454 (tracemalloc).

[issue21876] os.rename(src, dst) does nothing when src and dst files are hard-linked

[Aaron Swan]

New submission from Aaron Swan:

On Linux Red Hat os.rename(src,dst) does nothing when src and dst files are 
hard-linked.

It seems like the expected behavior would be the removal of the src file. This 
would be in keeping with the documentation that states: "On Unix, if dst exists 
and is a file, it will be replaced silently if the user has permission. "
