[issue22104] test_asyncio unstable in refleak mode

[STINNER Victor]

STINNER Victor added the comment:

> It may be related to the issue #17911.

I checked: it is. The strange reference count can be seen with a single test. 
Example:

$ ./python -m test -R 3:3: -m test_default_exc_handler_coro test_asyncio 
[1/1] test_asyncio
beginning 6 repetitions
123456
..
test_asyncio leaked [53, 53, -106] references, sum=0
test_asyncio leaked [15, 15, -30] memory blocks, sum=0
1 test failed:
test_asyncio

This test uses a coroutine which raises an exception. The exception is stored 
in a Task object. But the exception contains also a traceback which indirectly 
creates a reference cycle. For example, the zero_error_coro() coroutine of the 
test uses the free variable "self".

It's very difficult to find all objects of a reference cycle. We can try to 
break some cycles, it's already done Task._step() which sets self to None, but 
it's a waste of time. IMO the correct fix is to not store frame objects in an 
exception: see the issue #17911.

The 3.4 patch looks fine, please apply.

I'm -1 on the 2.7 patch. I think it would be better to add a _tkinter helper 
function to create Tcl byte array objects. Alternatively, the "binary format" 
command might help. OTOH, I don't care about 2.7, so feel free to do whatever 
you consider appropriate.

[issue22106] Python 2 docs 'control flow/pass' section contains bad example

[Charles Newey]

New submission from Charles Newey:

URL: https://docs.python.org/2/tutorial/controlflow.html#pass-statements

Quoted verbatim:
"""
The pass statement does nothing. It can be used when a statement is required 
syntactically but the program requires no action. For example:
>>>

>>> while True:
... pass  # Busy-wait for keyboard interrupt (Ctrl+C)
...

"""

While the example illustrates the point, it *may* give bad ideas to novice 
programmers reading it - "while True: pass" is an antipattern as it's very 
inefficient.

[issue22106] Python 2 docs 'control flow/pass' section contains bad example

[Ezio Melotti]

Ezio Melotti added the comment:

Do you have any suggestion?
The section already includes examples about empty classes and as placeholder 
inside functions, and the only other "realistic" situations I can think of is 
inside an except to ignore errors -- but that might be considered an 
anti-pattern too.
It could be used with "for" loops if you want to e.g. consume an iterator, or 
with the "with" statement if you want to create an empty file, but these cases 
are not very common.

[issue22106] Python 2 docs 'control flow/pass' section contains bad example

[Charles Newey]

Charles Newey added the comment:

Your point about using "pass" with the "with" statement sounds like a better 
example than using "pass" in a loop.

Perhaps even something like adding a note to the example to clarify it:
"""
# Don't use this in Python code - it is for illustrative purposes only
while True:
pass  # Busy-wait for keyboard interrupt (Ctrl+C)
"""

On the other hand -- one could argue that the documentation should not show 
"incorrect" uses of Python syntax at all.

[issue22107] tempfile module misinterprets access denied error on Windows

[Roger Upole]

New submission from Roger Upole:

_mkstemp_inner assumes that an access denied error means that it
has generated a filename that matches an existing foldername.
However, in the case of a folder for which you don't have permissions to
create a file, this means it will loop thru the maximum possible number of 
files.
This causes it to hang for several seconds and eventually return a bogus
FileExistsError.

Similar behaviour exists in 2.7.7, but it throws an IOError instead.

http://bugs.python.org/issue18849 seems to be where this was introduced.

Keep in mind that this is in one of the first sections of the tutorial, where

Maybe the comment could be changed to a simpler "loop forever (use ctrl+c to 
stop)" so that it doesn't suggest that this is the way to wait for keyboard 
interrupts and/or a note like "note that this will use 100% of the CPU" could 
be added as well.

Here's a fresh patch.  After discussing with Martin at EuroPython, I moved the 
implementation into Python/getargs.c, and the prototypes into modsupport.h.  
I'm still using the example of "repeat.new" to show what it looks like and how 
it works.  However I don't plan on checking the changes to repeat.new in when I 
check in the patch--I'd want to discuss it with Raymond first.

Antoine Pitrou added the comment:

Yes, it is. GNU readline will use a FILE*. Apparently, one can customize this 
behaviour, see http://cnswww.cns.cwru.edu/php/chet/readline/readline.html#SEC25

"""Variable: rl_getc_func_t * rl_getc_function
If non-zero, Readline will call indirectly through this pointer to get a 
character from the input stream. By default, it is set to rl_getc, the default 
Readline character input function (see section 2.4.8 Character Input). In 
general, an application that sets rl_getc_function should consider setting 
rl_input_available_hook as well. """

It is not obvious how that interacts with special keys, e.g. arrows.

Thank you Martin for your reviews. Here is updated 2.7 patch which implements 
your suggestion.

The disadvantage of this patch in comparison with first version is that it will 
not work with statically compiled embedded Python, when only stdlib is updated. 
I once broke re in bugfix release in such manner (by moving one constant from 
Python sources to C sources). On other hand, it is very unlikely that anyone 
uses Tkinter in such circumstances, and in any case this part of code is broken 
for now, so patch should not introduce new regression.

Close, but no cigar :).  Posted Rietveld comments to address the last two

Also, Victor has added os.get_blocking() and os.set_blocking(), which prevent 
your patch from applying cleanly (I tested against the parent of Victor's

[issue21580] PhotoImage(data=...) apparently has to be UTF-8 or Base-64 encoded

[Martin v . Löwis]

Martin v. Löwis added the comment:

The 2.7_2 patch looks good to me. I won't rule on the backwards compatibility 
implications, although I agree that this is unlikely to cause a regression (it 
would only if somebody updated the standard library only, *and* would use data= 
for PhotoImage). I'm unsure whether it was possible at all so far to use data= 
(with whatever argument); if you could have passed a non-buffer object 
successfully, this would break now.

[issue22108] python c api wchar_t*/char* passing contradiction

[Jonas Jelten]

New submission from Jonas Jelten:

The documentation and the code example at
https://docs.python.org/3.5/extending/embedding.html#very-high-level-embedding

#include 

int
main(int argc, char *argv[])
{
  Py_SetProgramName(argv[0]);  /* optional but recommended */
  Py_Initialize();
  PyRun_SimpleString("from time import time,ctime\n"
 "print('Today is', ctime(time()))\n");
  Py_Finalize();
  return 0;
}

contradicts the actual implementation of the code:
http://hg.python.org/cpython/file/tip/Include/pythonrun.h#l25

which leads to compiler errors. To fix them, ugly wchar_t to char conversions 
are needed.

Also, I was hoping, Python 3.3 finally switched from wchar_t to char and UTF-8.
at least that's how I understood PEP 393 http://python.org/dev/peps/pep-0393/

see also:

http://stackoverflow.com/questions/21591908/python-3-3-c-string-handling-wchar-t-vs-char


=> Are the docs wrong (which i hope are not, the example is straightforward and 
simple-stupid with a char*),
or is cpython wrong?

[issue6639] turtle: _tkinter.TclError: invalid command name ".10170160"

[Lita Cho]

Lita Cho added the comment:

I can make it worth such that it doesn't raise a Terminator error. This works 
great when working with Turtle on the command line. I basically check if the 
root exists for all Tk canvas calls. 

If it got destroyed, then it just returns. However, if you run the following 
recursive code, it will just keep popping up a window forever unless you Ctrl+C 
out of the program. So that is not going to work. I still believe raising an 
error is the proper approach.

[issue22108] python c api wchar_t*/char* passing contradiction

[Martin v . Löwis]

Martin v. Löwis added the comment:

You were misinterpreting PEP 393 - it is only about the representation of 
string objects, and doesn't affect any pre-existing API. Changing 
Py_SetProgramName is not possible without breaking existing code, so it could 
only happen in Python 4. 

A proper solution might be adding Py_SetProgramNameUTF8, but it could trick 
people into believing that argv[0] actually is UTF-8 on their system, which it 
might not be. Providing Py_SetProgramNameASCII might be better, but it could 
fail if argv[0] contains non-ASCII characters. Yet another solution could be to 
expose _Py_char2wchar to the developer.

In any case: yes, the example is outdated, and only valid for Python 2.

[issue17620] Python interactive console doesn't use sys.stdin for input

[Guido van Rossum]

Guido van Rossum added the comment:

I propose not to mess with GNU readline.  But that doesn't mean we can't try to 
fix this issue by detecting that sys.stdin has changed and use it if it isn't 
referring to the original process stdin.  It will be tricky however to make 
sure nothing breaks.

(The passage quoted from the GNU readline docs seems to imply that it's in 
non-blocking mode, and that the FD is a raw tty device, probably with echo off. 
 It will give escape sequences for e.g. arrow keys.)

My naive picture of ideal situation looks like this: When the interactive loop 
wants input, it just calls sys.stdin.readline, which delegates to 
sys.stdin.buffer.raw.readinto or .read, these can use GNU readline if available 
to get the data. May I ask, what's wrong with my picture?

[issue22109] Python failing in markupsafe module when running ansible

[R. David Murray]

R. David Murray added the comment:

As is indicated by the fact that markupsafe is in the 'site-packages' 
directory, markupsafe is a 3rd party library and is not part of the python 
standard library.  Most likely the version of markupsafe you have does not 
match the one ansible is expecting, but if that isn't enough info to solve your 
problem you should reach out for support from the anisble community.

[issue17620] Python interactive console doesn't use sys.stdin for input

[Guido van Rossum]

Guido van Rossum added the comment:

sys.stdin.readline() never delegates to GNU readline.  The REPL calls GNU 
readline directly.  There's clearly some condition that determines whether to 
call GNU readline or sys.stdin.readline, but it may not correspond to what you 
want (e.g. it may just test whether FD 0 is a tty).  Can you find in the 
CPython source code where this determination is made?

[issue16383] Python 3.3 Permission Error with User Library on Windows

[Zachary Ware]

Zachary Ware added the comment:

Jim, is there any way you could cut down your example to something small and 
self-contained?  It may be that the process of doing that leads to a problem in 
your code.  As it is, I cannot reproduce your error, or pick out what might be 
causing it.  From a brief glance, I have a few suggestions, though:

- Don't use sys.path[0] to determine where the file lives, it's not a reliable 
indicator.  Try using 'os.path.dirname(__file__)' instead (or 
'os.path.dirname(os.path.abspath(__file__))' if __file__ is relative, which 
should only be the case when passing the filename directly to Python as a 
relative path).
- Use 'os.path.join()' instead of adding strings to make paths.  Shouldn't 
matter, but makes things cleaner.
- (Unrelated, but) it's really not very nice to change the display color 
without changing it back.  On Windows, 'color' affects the entire window, not 
just your output, and it lasts past the death of your process.

Until you can provide a short (200 lines or less across 5 files or less) 
reproducer, there's not much we can do, so I'm closing the issue.  If you can 
provide one, please do so and I'll happily take a look!

[issue10572] Move test sub-packages to Lib/test

[Zachary Ware]

Zachary Ware added the comment:

I'm in favor of a move, especially for ctypes, sqlite3, unittest, and tkinter, 
and don't really see a reason not to move distutils and lib2to3.  The IDLE 
tests make a certain amount of sense to stay in the idlelib folder, just 
because IDLE is a special case.  I'm pretty sure that covers all of the 
packages that still have tests outside of the test package.

I think the movements should only happen on 3.5; merging forward isn't nearly 
as much of an issue here in the days of hg, and backports to 2.7 should be 
becoming fewer and farther between.

I'd be happy to take care of making the moves, if we can decide that it's worth 
doing (or if it's left up to me :).

[issue12806] argparse: Hybrid help text formatter

[paul j3]

paul j3 added the comment:

In http://bugs.python.org/issue22029 argparse
CSS white-space: like control for individual text blocks

I propose a set of `str` subclasses that can be used to define the wrapping 
style of individual text blocks. The idea is adapted from the HTML '' tag, 
and the CSS white-space: option.

`argparse.WhitespaceStyle` is a cover class that defines various utility 
methods, including `_str_format` which handles all of the `%` formatting.  The 
individual subclasses implement their own version of `_split_lines` and 
`_fill_text`.  I chose a standard set of classes based on the CSS white-space 
options:

Normal() - full white space compression and wrapping.  This is the default 
default of text in `argparse`.

Pre() - preformatting, the same as the `Raw` formatters

NoWrap() - Pre plus whitespace compression

PreLine()

PreWrap()

In `HelpFormatter`, `_split_lines`, `_fill_lines`, `_str_format` delegate the 
action to text's own methods.  Plain text is handled as `Normal()`.

I also defined a `WSList` class.  This is a list of Style class objects. It has 
the same API as the Style classes, iterating over the items.

Where possible these methods try to return an object of the same type as self.
--

Here I demonstrate two ways that these classes could be used to implement a 
hybrid formatter.

The first is a simple adaptation of the `PareML` formatter from 
`paraformatter.py`.  It shows how a custom style class could be defined.

The second is defines a `preformat` function, which converts the text block 
into a `WSList`, a list of style text objects.  The wrappable paragraphs are 
`Normal()`, the preformatted indented lines are `Pre()`. Blank lines are `Pre(' 
')`.

I've explored writing a `Hanging` class, which performs a hanging indent on

[issue17634] Win32: shutil.copy leaks file handles to child processes

[STINNER Victor]

STINNER Victor added the comment:

The issue has been fixed in Python 3.4 with the PEP 446. I close this issue.

If you would like to enhance shutil.copyfile() by using CopyFile() on Windows, 
please open a new issue.

[issue22110] enable extra compilation warnings

[Charles-François Natali]

New submission from Charles-François Natali:

The patch attached enables -Wsign-compare and -Wunreachable-code if supported 
by the compiler.
AFAICT, mixed sign comparison warning is automatically enabled by Microsoft's 
compiler, and is usually a good thing.
It does add some warnings though.

As for unreachable code, it's also usually a good thing, since it can be a 
source of bugs. Note that it's not enabled in debug mode, since in debug mode 
the code paths aren't the same.

[issue13123] bdist_wininst uninstaller does not remove pycache directories

[Paul Moore]

Paul Moore added the comment:

I'm not sure how relevant this is any more, as pip is the preferred installer 
these days and it cleanly uninstalls projects. At least for my usage, I no 
longer use wininst installers at all. I won't close this myself, though, as the 
issue still exists. But I won't object if it is closed as "wontfix".

My patch for the issue #22043 replaces the _PyTime_timeval structure (10^-6 
second resolution, 1 us) with a _PyTime_timespec structure (10^-9 second
