[issue1611944] sndhdr.what() does not recognize wav file

[Matthijs Kooijman]

Matthijs Kooijman <[EMAIL PROTECTED]> added the comment:

I've written a new patch, which works a bit better. You can find the new
patch attached.

I've restructed the patch to prevent code duplication. Also, it now
works with other chunks than bext (I had a file with a list chunk which
triggered my interest in this bug). This is done with a hardcoded list
of valid chunks. However, it seems that there is no complete list of
valid chunk types, so it might be better to remove the chunk type check
alltogether.

Also, this patch explicitly checks for overflow, since taking a slice of
a sequence does not seem to trigger an IndexError, but just return an
empty sequence.

[issue2636] Regexp 2.7 (modifications to current re 2.2.2)

[Jeffrey C. Jacobs]

Jeffrey C. Jacobs <[EMAIL PROTECTED]> added the comment:

Update 16 Sep 2008:

Based on the work for issue #3825, I would like to simply update the
item list as follows:

1) Atomic Grouping / Possessive Qualifiers (See also Issue #433030)
[Complete]

2) Match group names as attributes (e.g. match.foo) [Complete save
issues outlined above]

3) Match group indexing (e.g. match['foo'], match[3])

4) Perl-style back-references (e.g. compile(r'(a)\g{-1}'), and possibly
adding the r'\k' escape sequence for keywords.

5) Parenthesis-Aware Python Comment (e.g. r'(?P#...)') [Complete]

6) Expose support for Template expressions (expressions without repeat
operators), adding test cases and documentation for existing code.

7) Larger compiled Regexp cache (256 vs. 100) and reduced thrashing
risk. [Complete]

8) Character Classes (e.g. r'[:alphanum:]')

9) Proposed Engine redesigns and cleanups (core item only contains
cleanups and comments to the current design but does not modify the design).

9-1) Single-loop Engine redesign that runs 8% slower than current.
[Complete]

9-1-1) 3-loop Engine redesign that runs 10% slower than current. [Complete]

9-2) Matthew Bernett's Engine redesign as per issue #3825

10) Have all C-Python shared constants stored in 1 place
(sre_constants.py) and generated by that into C constants
(sre_constants.h). [Complete AFAICT]

11) Scan Perl 5.10.0 for other potential additions that could be
implemented for Python.

12) Documentation suggestions by Jim J. Jewett [Complete]

13) Add grouptuples method to the Match object (i.e. match.grouptuples()
returns (, , ) ) suitable for iteration.

14) UNICODE match group names, as per PEP-3131.

15) Add __doc__ strings and other Python niceties to the Pattern_Type,
Match_Type and Scanner_Type (experimental).

16) Implement any remaining TODOs and FIXMEs in the Regexp modules.

16-1) Allow for the disassociation of a source string from a Match_Type,
assuming this will still leave the object in a "reasonable" state.

17) Variable-length [Positive and Negative] Look-behind assertions, as
described and implemented in Issue #3825.

---

Now, we have a combination of Items 1, 9-2 and 17 available in issue
#3825, so for now, refer to that issue for the 01+09-02+17 combined
solution.  Eventually, I hope to merge the work between this and that issue.

I sadly admit I have made not progress on this since June because
managing 30 some lines of development, some of which having complex
diamond branching, e.g.:

01 is the child of Issue2636
09 is the child of Issue2636
10 is the child of Issue2636
09-01 is the child of 09
09-01-01 is the child of 09-01
01+09 is the child of 01 and 09
01+10 is the child of 01 and 10
09+10 is the child of 09 and 10
01+09-01 is the child of 01 and 09-01
01+09-01-01 is the child of 01 and 09-01-01
09-01+10 is the child of 09-01 and 10
09-01-01+10 is the child of 09-01-01 and 10

Which all seems rather simple until you wrap your head around:

01+09+10 is the child of 01, 09, 10, 01+09, 01+10 AND 09+10!

Keep in mind the reason for all this complex numbering is because many
issues cannot be implemented in a vacuum: If you want Atomic Grouping,
that's 1 implementation, if you want Shared Constants, that's a
different implementation. but if you want BOTH Atomic Grouping and
Shared Constants, that is a wholly other implementation because each
implementation affects the other.  Thus, I end up with a plethora of
branches and a nightmare when it comes to merging which is why I've been
so slow in making progress.  Bazaar seems to be very confused when it
comes to a merge in 6 parts between, for example 01, 09, 10, 01+09,
01+10 and 09+10, as above.  It gets confused when it sees the same
changes applied in a previous merge applied again, instead of simply
realizing that the change in one since last merge is EXACTLY the same
change in the other since last merge so effectively there is nothing to
do; instead, Bazaar gets confused and starts treating code that did NOT
change since last merge as if it was changed and thus tries to role back
the 01+09+10-specific changes rather than doing nothing and generates a
conflict.  Oh, that I could only have a version control system that
understood the kind of complex branching that I require!

Anyway, that's the state of things; this is me, signing out!

[issue3774] tkinter Menu.delete bug

[Dan OD]

Dan OD <[EMAIL PROTECTED]> added the comment:

It may be because I'm calling delete incorrectly (I don't think so - see 
below) but I'm getting an error

  File "C:\CCPN\ccpn\python\memops\gui\Menu.py", line 127, in 
deleteMenuItems
self.delete(0, Tkinter.END)
  File "C:\Python-2.6_svn\lib\lib-tk\Tkinter.py", line 2670, in delete
if c in self._tclCommands:
TypeError: argument of type 'NoneType' is not iterable

Which can easily be fixed with 

- if c in self._tclCommands:
+ if c and c in self._tclCommands:

line 2670 Tkinter.py

Should I create a patch or have I missed something? Thanks.

[issue3835] tkinter goes into an infinite loop (pydoc.gui)

[Guilherme Polo]

Guilherme Polo <[EMAIL PROTECTED]> added the comment:

If you remove the widget.config calls in GUI.ready you will notice the
problem "goes away", but note that this method is called from another
thread while you have a non-thread-safe tcl/tk lib (I'm assuming you
didn't compile it with --enable-threads). So.. using multiple threads in
Python while Tcl is compiled without --enable-threads isn't supported at
all.

To reproduce the problem try this (change Tkinter to tkinter if py3k):


import threading
import Tkinter

lbl = Tkinter.Label(text="hi")
threading.Thread(target=lambda: lbl.configure(text="hi there")).start()
lbl.mainloop()


If your tcl/tk libs weren't compiled with --enable-threads this should
get you an "TclError: out of stack space (infinite loop?)". A
documentation note may be added somewhere, but nothing much else is
going to happen (that is what I believe at least).

[issue3549] Missing IDLE Preferences on Mac

[Mitchell Model]

Mitchell Model <[EMAIL PROTECTED]> added the comment:

Compiling with configure --enable-framework, from updated SVN sources
today plus the change suggested in issue 3628, IDLE works with both
2.6rc1 and 3.0b3.  There is still no options menu, but there is now a
Preferences item on the IDLE menu, where this more appropriately belongs
on the Mac.  However, IDLE Help still refers to the Options menu; on the
Mac, the Help information should refer to the Preferences item on the
IDLE menu instead of Options item, or at least add a comment that that's
where the functionality of Options appears on the Mac.

[issue3884] turtle in the tkinter package?

[Kirill Simonov]

New submission from Kirill Simonov <[EMAIL PROTECTED]>:

I wonder why the module 'turtle' was moved to the 'tkinter' package.  It
is not a part of Tk, it does not provide new or extend existing tkinter
API.  While it uses tkinter, so do pydoc or idle; this is just an
implementation detail.  If some day a new GUI library replaces tkinter
in the standard Python library, turtle's interface will not have to be
changed, only the implementation.  Moreover this change unnecessarily
breaks all existing demos and tutorials that use turtle.  Why do this if
it does not give any substantial benefits?  Finally, 'import turtle' is
easier than 'from tkinter import turtle' for complete newbies in
programming, who are the primary users of this module.

So I propose to keep turtle a top-level module as it was in Python 1 and 2.

[issue3885] errors on _bsddb creation and dealloc

[STINNER Victor]

New submission from STINNER Victor <[EMAIL PROTECTED]>:

I found two differents bugs using Fusil the fuzzer.

(1) On db_env_create() error in newDBEnvObject(), self->db_env is not 
set and so use of this pointer may crashs.

(2) DBEnv_dealloc() may raise an exception (DBEnv_close_internal() 
calls makeDBError()) but the garbage collector dislike exceptions!

Example of (2):

$ python
>>> import gc, _bsddb; env=_bsddb.DBEnv(3); del env
>>> gc.collect(); gc.collect()
Exception bsddb.db.DBNoServerError: (-30992, 'DB_NOSERVER: Fatal

fields. The ZipFile object croaks at the call to the 
ZipInfo._decodeExtra() call when it could really just ignore the error.

Example of traceback:

>>> zf = zipfile.ZipFile('bad.zip', 'r')
Traceback (most recent call last):
  File "", line 1, in 
  File "zipfile.py", line 346, in __init__
self._GetContents()
  File "zipfile.py", line 366, in _GetContents
self._RealGetContents()
  File "zipfile.py", line 424, in _RealGetContents
x._decodeExtra()
  File "zipfile.py", line 267, in _decodeExtra
tp, ln = unpack('

[issue3884] turtle in the tkinter package?

[Brett Cannon]

Brett Cannon <[EMAIL PROTECTED]> added the comment:

As Benjamin said, it's too late in the release cycle to change this.

Plus turtle is entirely Tk-dependent so putting in the package makes
sense to me. It also isn't important enough to be a top-level package.
Finally, I disagree that telling a newbie to type ``from tkinter import
turtle`` is any more difficult than to tell them to type ``import
tkinter``; if they don't know about importing then either form won't
make sense to them.

[issue3885] errors on _bsddb creation and dealloc

[Jesús Cea Avión]

Jesús Cea Avión <[EMAIL PROTECTED]> added the comment:

Good catch. I've patched my private branch. Following 2.6 patches, if
anybody can provide a review, since we are in RC status.

I was wondering if we must protect other objects from raising exceptions
in GC. For example, DB objects.

What do you think?.

(I have broken my left wrist ten days ago. If you can write a testcase
showing the issue and a patch for it, would be very nice).

[issue3885] errors on _bsddb creation and dealloc

[STINNER Victor]

STINNER Victor <[EMAIL PROTECTED]> added the comment:

Here is a test to reproduce the crash. I don't know db_env_create() 
function, so I don't know what are "invalid arguments". So I used 
~DB_RPCCLIENT. "gc.collect()" is to detect the bug (2).

About other objects dealloc method...

DBEnv_dealloc()
  `-> DBEnv_close_internal(): RETURN_IF_ERR()
DB_dealloc()
  `-> DB_close_internal(): RETURN_IF_ERR()
DBC_dealloc() 
  `-> DBC_close_internal(): RETURN_IF_ERR()
DBSequence_dealloc()
  `-> DBSequence_close_internal(): RETURN_IF_ERR()
DBTxn_dealloc()
  `-> DBTxn_abort_discard_internal(): RETURN_IF_ERR()

DBLock_dealloc() looks ok.
