[issue19690] test_logging test_race failed with PermissionError

[Vinay Sajip]

Vinay Sajip added the comment:

> What is the status of this issue?

Sorry, it's been off my radar - I wonder if it has become more common recently. 
It's hard to reproduce, and tweaking timeouts might make it disappear, but it's 
a trial-and-error situation because I can hardly ever get the error to occur. 
The base race condition can't be eliminated, unfortunately.

[issue21951] tcl test change crashes AIX

[STINNER Victor]

STINNER Victor added the comment:

The failing assertion means that the method raised an exception and returned a 
result, or failed but didn't raised an exception. According to the gdb trace, 
the function failed (res is NULL). You can display the current exception in gdb 
using: "print PyErr_Occurred()" (NULL if there is no exception).

Please run test_tcl on AIX with attached test_tkinter.patch applied.

[issue21933] Allow the user to change font sizes with the text pane of turtledemo

[Terry J. Reedy]

Terry J. Reedy added the comment:

I am aware of this because the Windows has the same behavior. As I noted in my 
post to #17642, I consider this behavior a tolerable glitch rather than a 
patch-blocking bug for turtledemo because the text is relatively short and read 
only, so there is no issue of needing to keep a cursor in place and visible. 
The issue would be different for Idle if indeed this is a tk rather than turtle 
problem. Also, people would typically only move a few clicks up or down, and 
scrolling up when already at the top of the file has no effect.  So I do not 
regard this as a bug for this issue and regard this as still closed unless you 
happen to have thought of a workaround.

If you don't have a fix now, you could open a separate issue to investigate 
whether the linkage is a tk, tkinter, or turtle bug.

As part of #17535, I discovered that when a Text widgets change the font size, 
they scroll up, down too far (or down and up too far), and back to where they 
should be.  This is not visible with small files like the turtle examples, but 
is with 3000-line files like idlelib/EditorWindow.py, especially when line 
numbers are enabled.  My test script attached to #17535 shows that Text indeed 
calls scrollbar.set 3 times.  I regard this as a tk bug.  My point here is that 
Text widget font size changes are a bit flaky even without the mousewheel issue.

Thanks for your report and sorry it took so long to respond!

You are absolutely right that __name__ was a broken feature, which is why we 
removed it in Python 3.2. See issue #10489. For Python 2.7 you can use the 
backport, available on PyPI.

[issue21356] Support LibreSSL (instead of OpenSSL): make RAND_egd optional

STINNER Victor added the comment:

> The PyPy patch (and some discussion) is here:

Your patch checks at runtime if libssl comes with RAND_egd:

   HAVE_OPENSSL_RAND_EGD = rffi_platform.Has('RAND_egd')

In CPython, the _ssl module is compiled in C. How can we check if libssl 
provides RAND_egd() or not at compile time?

Is there a way to check if libssl is OpenSSL or LibreSSL?

[issue22335] Python 3: Segfault instead of MemoryError when bytearray too big

[swanson]

New submission from swanson:

On Python 3, but not Python 2, you crash with a Segmentation Fault instead of 
getting a MemoryError as expected.  It seems to only be a problem with 
bytearray, not with other things like tuple:

compare to:

[issue22336] _tkinter should use Python PyMem_Malloc() instead of Tcl ckalloc()

[STINNER Victor]

New submission from STINNER Victor:

The PyMem_Malloc(size) function has a well defined behaviour: if size is 0, a 
pointer different than NULL is returned. It looks like ckalloc(size) returns 
NULL if the size is NULL: see issue #21951 (bug on AIX).

Moreover, memory allocated by ckalloc() is not traced by the new tracemalloc 
module!

Attached patch replaces calls to ckalloc() and ckfree() with PyMem_Malloc() and 
PyMem_Free(). It may fix the issue #21951 on AIX.

There is still a call to ckfree() in Tkapp_SplitList(). This memory block is 
allocated internally by Tcl, not directly by _tkinter.c.

Thanks. I found and fixed a bug in AsObj() for tuple and list. It looks like 
ckalloc(size) returns NULL if size is 0. Please update Python, compile and run 
test_tcl to see if you get a MemoryError exception instead of a crash.

I just created the issue #22336 which may fix this issue if my analysis was 
correct. It uses PyMem_Malloc(size) which has a well-defined behaviour when 
size is 0.

[issue21933] Allow the user to change font sizes with the text pane of turtledemo

[Terry J. Reedy]

Terry J. Reedy added the comment:

Great. That works better on Windows too. Attached is an augmented patch to also 
move the other size bindings to text (I verified that 'bind_all' is needed), 
move the resize binding back to where it was, delete the now-empty binding 
function, and add a not to the docstring that the mousewheel only resizes when 
the mouse is over the text.  Please verify that this also works for non-windows.

[issue17535] IDLE: Add an option to show line numbers along the left side of the editor window, and have it enabled by default.

[Terry J. Reedy]

Terry J. Reedy added the comment:

And if you enable code context in the other window, neither will have the 
checkmark. As I said, the one button is being used to toggle two things: the 
state of the current window and the default for future windows, and the 
checkmark only indicates the second. I agree that this is confusing.

Terry J. Reedy added the comment:

There has been more discussion of code context toggling in #17535, msg225411

state of the current window and the default for new windows.

PEP 434 ratified my comment about new Idle features not having to wait.  #3068 
is about adding an extension configuration dialog that will be needed to

[issue22337] Modulus not returning proper remainder

[DenisCrnic]

New submission from DenisCrnic:

Modulus is returning wrong remainder when working with negative numbers.
For example 34%-3 should return 1, but it returns -2.

34/-3=-11, remainder: 1, proof: -11*(-3)+1=34 <--- Math logic (works in Java 
for example)

but python goes like that:
34/-3=12, remainder: -2. proof: -12*(-3)+(-2)=34 <--- Python logic (works)
I know that python is looking for the int which is the closest to the a (a%b), 
and is divisible with it, but in this case that's not right. it should seek for 
the closest integer, which is lower than a, in this case 33

If explanation is not clear enough, reply me, i'll take more time to make it 
clear.
maybe my theory is wrong, and python syntax works better than in Java.

[issue22337] Modulus not returning proper remainder

[R. David Murray]

R. David Murray added the comment:

This is, indeed, the way Python works.  See

https://docs.python.org/3/reference/expressions.html

where you will find:

The modulo operator always yields a result with the same sign as its second 
operand (or zero); the absolute value of the result is strictly smaller than 
the absolute value of the second operand

[issue22117] Rewrite pytime.h to work on nanoseconds

[STINNER Victor]

STINNER Victor added the comment:

And now, something completly different.

nanosec-wip.patch is a work-in-progress patch to use a unified (64 bits) 
integer type to store a timestamp: _PyTime_t. The type is written to be opaque, 
the unit is undefined, you must use functions to convert from and to this type. 
Well, in fact it's just a number of nanoseconds.

The patch is large:

 Include/pytime.h  |  125 ++-
 Modules/_datetimemodule.c |   43 ++--
 Modules/_testcapimodule.c |   25 +-
 Modules/_threadmodule.c   |  156 +++---

 Modules/timemodule.c  |   40 ++-
 Python/pytime.c   |  480 +-
 12 files changed, 645 insertions(+), 471 deletions(-)

Conversion functions require a rounding mode.

I didn't update all tests yet. For example, test_datetime crash, test_time and 
test_threading fail. There are also 3 remaining FIXME for myself in pytime.c.

[issue21228] Missing enumeration of HTTPResponse Objects methods of urllib.request.urlopen's http.client.HTTPResponse?

[Evens Fortuné]

Evens Fortuné added the comment:

Hi,

>From my limited experience reporting documentation issues, I see that it's 
>better to submit a patch than to only report an issue. So, I've tried to look 
>into the source code to figure out what was going on. I have attached a patch 
>that I'm submitting to you for review hoping I doing everything right.

What was reported as ambiguous in this issue is the description of the return 
value of the function urllib.request.urlopen() for http and https URLs. It was 
mentionned that it should be an http.client.HTTPResponse object but it implied 
that something may have been different about this object. 

To understand why I'm may now be able to assert what's being said in that 
patch, follow me in the source code. It's based on revision c499cc2c4a06. If 
you don't care about all the walkthrough you can skip to step 9.

   1. We want to describe the return value of the urllib.request.urlopen() for 
http and https URLs
   2. The urlopen() function is defined in Lib/urllib/request.py starting on 
line 138. Its return value is the return value function of the opener.open() 
method (line 153)
  * This opener object is defined in one of these locations:
 * On line 150 as the return value of the module function 
build_opener() (this return value is cached in the _opener module variable)
 * On line 152 as the value cached in the _opener module variable
 * On line 148 still as the return value of the module function 
build_opener() in the case if you want to access an HTTPS URL and you provide a 
cafile, capath or cadefault argument
  * So either way, the opener object come from the build_opener directly or 
indirectly.
   3. The build_opener() function is defined starting on line 505. Its return 
value (line 539) is an instance of the OpenerDirector class (line 514). The 
OpenerDirector class is defined starting on line 363.
  a. Before returning its return value, after some checks (lines 522-530, 
535-536), build_opener() calls the OpenerDirector().add_handler() with an 
instance of some of the classes defined in the default_classes list (line 
515-518). What matters to us is the HTTPHandler class and the HTTPSHandler 
class (line 520).
  b. The OpenerDirector().add_handler() method (line 375) takes the 
HTTPHandler class (line 1196) and:
 * Insert the HTTPHandler.http_open() method in the list stored as the 
value of OpenerDirector().handle_open['http'].
 * Insert the HTTPHandler.http_request() method in the list stored as 
the value of OpenerDirector().process_request['http'].
  c. For HTTPSHandler (line 1203) is the same thing but :
 * HTTPSHandler.https_open() for OpenerDirector().handle_open['https']
 * HTTPSHandler.https_request() for 
OpenerDirector().process_request['https']
   4. I remind you that we are looking for the return value of the method 
open() of an instance of the OpenerDirector class (see point number 2). This 
method is defined starting on line 437.
   5. The OpenDirector.open() method's return value is the response variable 
(line 463)
   6. This variable is defined on lines 461 and 455.
  a. The loop on lines 458-461 tries to find in his handlers (the 
OpenerDirector().process_response dictionary) a response processor (a 
XXX.http_response() method) which isn't defined in HTTPHandler or HTTPSHandler. 
(a http_response() method is defined in HTTPErrorProcessor [line 564] and in 
HTTPCookieProcessor [line 1231] but in each of these cases, these classes don't 
modify the response value)
  b. So response variable's value is the return value of 
OpenerDirector()._open(req, data) on line 455. 
 * The req argument is a Request instance (line 440) or something that 
has the same interface, I guess (line 442). The Request class is defined on 
line 253.
 * The data argument is included in the constructor of the Request 
instance (line 440 and then on line 262) or added to the object provided (line 
444). Afterwards, it won't be used directly (OpenerDirector()._open() receives 
it as an argument but won't use it in its body)
   7. OpenerDirector()._open() is defined on line 465. It will call 
OpenerDirector()._call_chain() up to three times depending on whether a result 
has been found (lines 468-469, 474-475). 
  * OpenerDirector()._call_chain() is defined on line 426. All it does is 
calling the handlers registered in the dictionnary provided (the chain 
argument) until one returns something else than None and returns it.
  * In our case (retrieving http and http resources):
 a. The first call (line 466) will return None since HTTPHandler or 
HTTPSHandler don't have a default_open() method (in fact, no handler defined in 
this file has a default_open() method)
 b. The second call will work since HTTPHandler.http_open() (line 1198) 
and HTTPSHandler.https_open() (line 1212) exists. Their return values will be 
enventually what we are lookin

[issue21907] Update Windows build batch scripts

[David Bolen]

David Bolen added the comment:

While troubleshooting an issue with test_distutils consistently failing on my 
XP buildbot, I narrowed it down to the test.bat change to use run_tests.py.  I 
don't yet know fully what's happening, but after replacing the new test.bat 
with the older version (that calls rt.bat) everything works fine.

Doing so also appears to clean up the stdin encoding problem (which was causing 
a consistent failure in test_capi).

As suggested by Zachary in msg222621, and given the status of XP going forward, 
I think it may be best, at least for now, to revert back to the traditional 
test.bat/rt.bat combination under XP, which has been stable for a long time.  
At least until some further work can be done to discover what's happening with 
the new approach, assuming it's desired at some point under XP.

Attached is a simple test.bat update that reverts to the older rt.bat approach 
but only under XP.

[issue22290] "AMD64 OpenIndiana 3.x" buildbot: assertion failed in PyObject_Call() in test_subprocess.test_preexec()

[STINNER Victor]

STINNER Victor added the comment:

I reproduced the crash with pyfailmalloc. The problem is that 
_posixsubprocess.fork_exec() calls gc.enable() on error when preexec_fn is set 
and the garbage collector was disabled (by fork_exec). Calling a function with 
an exception set is forbidden.

Attached patch fixes this issue, but fix also error handling in fork_exec() and 
add some unit tests.

[issue22339] Incorrect behavior when subclassing enum.Enum

[Kiss György]

New submission from Kiss György:

There is a small inconvenience in the ``enum`` module.
When I subclass ``enum.Enum`` and redefine the ``value`` dynamic attribute, the 
aliasing behavior doesn't work correctly, because ``member.value`` is used in 
some places instead of ``member._value_``.
I attached a patch where I fixed all these places. This causes no harm to the 
internal working, but makes subclassing behave correctly.

[issue22339] Incorrect behavior when subclassing enum.Enum

[Kiss György]

Kiss György added the comment:

Yes, sorry I forgot about that. Here is a minimal example:


from enum import EnumMeta, Enum
from types import DynamicClassAttribute


class _MultiMeta(EnumMeta):
def __init__(enum_class, cls, bases, classdict):
# make sure we only have tuple values, not single values
for member in enum_class.__members__.values():
if not isinstance(member._value_, tuple):
raise ValueError('{!r}, should be tuple'.format(member._value_))

def __call__(cls, suit):
for member in cls:
if suit in member._value_:
return member
return super().__call__(suit)


class MultiValueEnum(Enum, metaclass=_MultiMeta):
@DynamicClassAttribute
def value(self):
"""The value of the Enum member."""
return self._value_[0]

class IncorrectAliasBehavior(MultiValueEnum):
first = 1, 2, 3
second = 4, 5, 6
alias_to_first = 1, 2, 3


When you call IncorrectAliasBehavior.alias_to_first, the documentation says it 
should return IncorrectAliasBehavior.first, but in this case it returns 
IncorrectAliasBehavior.alias_to_first, because canonical_member.value is 
referenced on line 162, and so it returns the redefined value, not the 
internally used one.
This was very confusing for me.

[issue1152248] Add support for reading records with arbitrary separators to the standard IO stack

[Martin Panter]

Martin Panter added the comment:

Related:
* Issue 563491: 2002 proposal for parameter to readline, rejected at the time
* Issue 17083: Newline is hard coded for binary file readline

Fixing this issue for binary files would probably also satisfy Issue 17083.

[issue1508475] transparent gzip compression in urllib

[Martin Panter]

Martin Panter added the comment:

Related: Issue 1243678, which includes a patch for “httplib” (now known as 
“http.client”?). That patch looks like it sets Accept-Encoding and decodes 
according to Content-Encoding. However I suspect it is also trying to be too 
“transparent” at the wrong level and would have many of the problems already 
mentioned here.

[issue21228] Missing enumeration of HTTPResponse Objects methods of urllib.request.urlopen's http.client.HTTPResponse?

[Martin Panter]

Martin Panter added the comment:

With this patch, there is no longer any implication that the returned object 
implements the “addinfourl” interface. Perhaps that should be added back. Or 
maybe add it to the HTTPResponse class documentation itself? There is a comment 
that says the methods are there “for compatibility with old-style urllib 
responses”, although it seems to me they also make the class compatible with 
Python 3’s new “urllib”:

http://hg.python.org/cpython/file/c499cc2c4a06/Lib/http/client.py#l772

It is good to document the “msg” attribute and its inconsistency, since I have 
found this is required to implement your own BaseHandler.default_open(). 
However I’m not so sure if it is necessary to document the “url” attribute. Why 
not encourage using geturl() instead, since it is already documented, at least 
for non-HTTP responses?

I also saw a comment against the “msg” attribute which mentions deprecating 
something, but it is not clear what:
http://hg.python.org/cpython/file/c499cc2c4a06/Lib/urllib/request.py#l1187
