Gabriel Genellina  added the comment:

So this patch should fix it. But I cannot fire the bug using the posted 
example, and there are no test cases for this module yet, so I could 
not test it.

[issue6647] warnings.catch_warnings is not thread-safe

[Gabriel Genellina]

New submission from Gabriel Genellina :

warnings.catch_warnings is a context manager supposed to save and 
restore warnings filters, and optionally record all warnings issued.

But it does so in a completely thread-unsafe way, by replacing the 
module's "showwarning" and "filters" attributes on enter, and restoring 
them on exit. If the __enter__ / __exit__ calls of two threads overlap, 
after leaving the last block the warnings state is not the same as the 
original state, as it should be.

I don't know how to fix this, other than using locks (that could block 
indefinitely) or severely restricting how catch_warnings may be used. 
At least, this issue should be documented.

[issue6526] importlib.import_module affects permissions of .pyc files subsequently created by import

[Brett Cannon]

Brett Cannon  added the comment:

OK, I need a double-check here, David. At this point I have narrowed it 
down to this code triggering it::

  finder = importlib._bootstrap._PyPycFileFinder('.')
  sys.path_importer_cache['.'] = finder

And I am not kidding, that assignment is required. I might be able to 
narrow the code down further in _PyPycFileFinder, but I wanted to double-
check that I have not gone insane and that these two lines do indeed 
trigger the problem.

Rather pessimistic way to see it :) I've always read it as "operation

Richard Stevens, MSDN
(http://msdn.microsoft.com/en-us/library/ms741540(VS.85).aspx) and
possibly several other authors and places will tell it is possible to
happen. I've always seen this being handled as "try again later".

[issue6562] OverflowError in RLock.acquire()

[David Roberts]

David Roberts  added the comment:

Ok, so if it's a bug in (Py)Qt then I'm not going to worry about it.

I've managed to fix the issue in my case anyway, by (essentially) replacing:
image = Image.open(fname)
image.load()
tile = ImageQt(image)
with (the much more obvious way to do it):
tile = QImage(fname)

[issue5712] tkinter - askopenfilenames returns string instead of tuple in windows 2.6.1 release

[Guilherme Polo]

Guilherme Polo  added the comment:

> With 2.6.2 on Windows, I get filenames surrounded by {}, all in a

This string surrounded by { } indicates it is supposed to be a tcl
list, which didn't get converted but should be done by tkFileDialog.

> The change may be related to the new Tk library used, not directly the

It could be, or not. A simple solution would be to call the splitlist
function from _tkinter on that string, which tkFileDialog should be
doing indifferently of expecting objects from _tkinter or not.

> (BTW, I don't see *any* unit tests for tkinter :( )

There are some one a separated branch for now, but it doesn't include
tkFileDialog yet.

[issue2335] Backport set literals

[Guido van Rossum]

Guido van Rossum  added the comment:

Raymond, I know you see this differently, but personally I don't see a
problem with 2.7 getting additional backports of 3.x features, as long
as they are backwards compatible. While personally I wouldn't spend
effort on this particular backport, I don't see a problem when someone
volunteers a patch. In this specific case, I am fine with accepting set
literals and set comprehensions as new syntax. I do agree that repr()
needs to be kept the same as it was under 2.6.

[issue6636] Non-existant directory in sys.path prevents further imports

[Gabriel Genellina]

Gabriel Genellina  added the comment:

Looks like an optimization for the common case when directories aren't 
created "on the fly". Your proposal would slow down all imports (a 
typical sys.path actually contains a few nonexisting directories).

Quoting PEP302:

The results of path hook checks are cached in
sys.path_importer_cache, which is a dictionary mapping path entries
to importer objects.  The cache is checked before sys.path_hooks is
scanned.  If it is necessary to force a rescan of sys.path_hooks, it
is possible to manually clear all or part of
sys.path_importer_cache.

So the problem is that some cached data is outdated. In this case, 
after creating a directory that might be listed in sys.path, you should 
clear the cached entries using either of these lines:

sys.path_importer_cache.pop("/tmp/foobar", None)
sys.path_importer_cache.clear()

and then your test code succeeds.

(I'd close the issue as 'invalid')

[issue6641] strptime doesn't support %z format ?

[David House]

David House  added the comment:

>From the documentation from time.strptime() (which acts the same as
datetime.strptime()):

"Only the directives specified in the documentation [of time.strftime()]
are supported. Because strftime() is implemented per platform it can
sometimes offer more directives than those listed. But strptime() is
independent of any platform and thus does not necessarily support all
directives available that are not documented as supported."

So I think invalid.

[Vincent Legoll]

Vincent Legoll  added the comment:

If the macro_lines is not emptied upon end of parsing a macro
definition, if there's another macro definiton it will 'inherit' the
lines from the previous one, which could very well be uncool.

The use before definition should also be fixed.

Please advise if a better fix would be to completely remove the Netrc
class from ftplib, or replace it with a compatibility wrapper that use
the netrc module.

[issue6628] IDLE freezes after encountering a syntax error

[brian]

brian  added the comment:

I have Tcl/tk 8.4.7 installed.

To reproduce the hang on my machine:
open IDLE
new window
enter the following code:
  for i in range(10)
  print(i)
run module (saved as test.py)
interpreter complains (shell is still responsive at this point)
fix the code by adding the colon after the for loop
run module again (at this point, IDLE hangs)
While the top menu bar is responsive, all options are greyed out, and
apple-Q doesn't work. Force-quit is necessary to shut IDLE down. Also,
the force-quit menu doesn't show IDLE as being unresponsive, whereas
usually there will be a red alert for an unresponsive program.

Hope this helps

[issue6644] cmathmodule.c: Extra comma in enum - fails on AIX

[Sridhar Ratnakumar]

New submission from Sridhar Ratnakumar :

Please the remove extra comma in Modules/cmathmodule.c

64 :eimes enum special_types {
65 :eimes   ST_NINF,/* 0, negative infinity 
*/
66 :eimes   ST_NEG, /* 1, negative finite 
number (nonzero) */
67 :eimes   ST_NZERO,   /* 2, -0. */
68 :eimes   ST_PZERO,   /* 3, +0. */
69 :eimes   ST_POS, /* 4, positive finite 
number (nonzero) */
70 :eimes   ST_PINF,/* 5, positive infinity 
*/
71 :eimes   ST_NAN, /* 6, Not a Number */
72 :eimes };

To see why this is necessary, peruse a similar issue reported earlier:

[issue6562] OverflowError in RLock.acquire()

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc  added the comment:

This error is certainly due to a C function that sets an exception but
does not return an error value.
When running with a debug build of python, you will see "XXX undetected
error" printed to stderr.

[issue6643] joining a child that forks can deadlock in the forked child process

[Reid Kleckner]

New submission from Reid Kleckner :

This bug is similar to the importlock deadlock, and it's really part of
a larger problem that you should release all locks before you fork. 
However, we can fix this in the threading module directly by freeing and
resetting the locks on the main thread after a fork.

I've attached a test case that inserts calls to sleep at the right
places to make the following occur:
- Main thread spawns a worker thread.
- Main thread joins worker thread.
- To join, the main thread acquires the lock on the condition variable
(worker.__block.acquire()).
== switch to worker ==
- Worker thread forks.
== switch to child process ==
- Worker thread, which is now the only thread in the process, returns.
- __bootstrap_inner calls self.__stop() to notify any other threads
waiting for it that it returned.
- __stop() tries to acquire self.__block, which has been left in an
acquired state, so the child process hangs here.
== switch to worker in parent process ==
- Worker thread calls os.waitpid(), which hangs, since the child never
returns.

So there's the deadlock.

I think I should be able to fix it just by resetting the condition
variable lock and any other locks hanging off the only thread left
standing after the fork.

[issue6642] returning after forking a child thread doesn't call Py_Finalize

[Reid Kleckner]

New submission from Reid Kleckner :

I attached a test case to reproduce.

Here is what it does:
- The main thread in the parent process starts a new thread and waits
for it.
- The child thread forks.
- The child process creates a daemon thread, and returns.
- The parent process (in the thread that forked) calls os.waitpid(childpid).

What should happen is that the forked child process should terminate
because it shouldn't wait for the daemon thread, and
os.waitpid(childpid) should return after that, and then the main thread
should return from thread.join().

What happens is that because it was a child thread that forked, the C
stack starts inside of the pthread wrapper (or equivalent) instead of
main.  So when child process returns, it doesn't know that it is now the
main thread, and it doesn't execute Py_Finalize.  Furthermore, pthreads
doesn't call sys_exit_group because it thinks that it is a lone thread
returning, and it doesn't want to terminate the entire process group. 
When you look at it with 'ps f', this is what it looks like:

[issue4832] idle filename extension

[Guilherme Polo]

Guilherme Polo  added the comment:

> With this new patch, is it possible to create a file without extension
> on Windows?

It is tricky but, answering your question, you could enter a name
ending with a period to save without an extension.

It seems this isn't going anywhere then. The default behaviour on
Linux is to get the .py already, so this patch changes nothing there.
On Windows no extension is set by default, and with this patch it is
always .py if no extension is specified.

[issue4765] IDLE fails to "Delete Custom Key Set" properly

[Guilherme Polo]

Guilherme Polo  added the comment:

Interesting, this is reproducible in any version under any OS but it is
more noticeable under Windows. In the step 6 you mentioned, IDLE is busy
printing warnings that you will never see if you don't run IDLE from a
terminal. Also, when you tried restarting IDLE I believe it were
actually starting up but wasting a lot of time with this non-existing
key binding.

The problem is that when you ask to delete a custom key set, given the
steps pointed out, IDLE will first remove the custom key bindings and
then will try to remove the bindings associated with the just removed
key bindings which will generate a lot of warnings since they no longer
exist.
A simple solution is to invert some steps when "Apply" is pressed so the
bindings are removed while they still exist in the config-keys.cfg file.
But if you have a config-keys.cfg like you described below and start
IDLE, it will still take a long time to load (at least it does in a
virtual machine here).

[issue6628] IDLE freezes after encountering a syntax error

[Ned Deily]

Ned Deily  added the comment:

I can't reproduce a hang with the python.org 3.1 IDLE on either 10.4 or 
10.5 and with the system Tcl/Tk or with a newer Active Tcl/Tk 8.4 
installed.  Do you have another version of Tcl/Tk installed in 
/Library/Frameworks?  Can you give a step-by-step procedure for 
reproducing the problem you see?

[issue3961] Arrows key do not browse in the IDLE

[Guilherme Polo]

Guilherme Polo  added the comment:

Richard, IDLE doesn't support browsing the history of the commands
entered (see issue2704), so I believe this is not related to IDLE and I
believe you meant to talk about the standard python shell.

Since you have compiled python yourself it is possible that you didn't
have the development package of readline installed (it is
libreadline5-dev on ubuntu), which would cause the problem you described
when using the standard python shell.

[issue6562] OverflowError in RLock.acquire()

Fredrik Lundh  added the comment:

PIL is completely thread-agnostic, so I not sure there's anything PIL can 
do to fix this.

(and ImageQt is of course an interface to PyQt, which is an interface to 
Qt, which consists of a *lot* more than 50 lines...)

[David Roberts]

David Roberts  added the comment:

I think I've narrowed it down to the ImageQt class provided by PIL -
commenting out the reference to this (in the constructor of the Tile
class referenced by TileProvider.run) stops the errors.

So how do I go about determining where the problem with ImageQt lies?
(It's only ~50 lines, so there can't be too many things that could
possibly go wrong)

[issue6637] non-empty defaultdict .copy() fails returning empty dict

[Tom Clarke]

Tom Clarke  added the comment:

NB - (discussion of significance of this bug)

Defaultdict called with no argument is anomalous & this problem can be 
avoided in such cases by using dict. However this is not possible if 
default value can change and the documentation specifically defines 
behavior when called with no parameter, so this case is allowed.

Furthermore this bug is unpleasant because when the default values are 
never used it is very counterintuitive to imagine that the an error in 
the default value function could have any effect on the output.

Possible solutions:
(1) raise error in this case, change documentation (I prefer)
(2) mend behaviour in this case

Best wishes, Tom
