[issue4347] Circular dependency causes SystemError when adding new syntax

[Thomas Lee]

Thomas Lee  added the comment:

This would appear to be another build quirk: Lib/symbol.py needs to be
regenerated if Grammar/Grammar changes.

Brett, do you think it would be okay for this file to be generated
automatically as part of the build process? I can't think of any good
reason why this should continue to be a manual task.

Lib/token.py is in a similar boat, except its dependency is on
Include/token.h

Whatever the decision, I'll provide another review/functional patch pair.

[issue1818] Add named tuple reader to CSV module

[Jervis Whitley]

Jervis Whitley  added the comment:

An implementation of a namedtuple reader and writer.

Created a writer for the case where user would like to specify
desired field names and default values on missing field names.

e.g.
mywriter = NamedTupleWriter(f, fieldnames=['f1', 'f2', 'f3'], 
restval='missing')

Nt = namedtuple('LessFields', 'f1 f3')
nt = Nt(f1='one', f2=2)

mywriter.writerow(nt) # writes one,missing,2

any thoughts on case where defined fieldname has a leading 
underscore? Should there be a flag to silently ignore? 

e.g. 
if self._ignore_underscores:
   fieldname = fieldname.lstrip('_')

Leading underscores may be present in an unsighted csv file,
additionally, spaces and other non alpha numeric characters pose 
a problem that does not affect the DictReader class. 

Cheers,

[issue5134] Compiler warnings in sqlite module

[Ulrich Eckhardt]

Ulrich Eckhardt  added the comment:

"What specific file would you put these pragmas into? Are you perhaps
proposing to change upstream code?"

I would put it into the only sourcefile there is, and yes, I would
change upstream code. Obviously, it would be better to get upstream to
incorporate those changes...

Other than that, I'm +1 for your solution using the vsprops file, which
looks clean to me.

[issue924806] email.Header.Header() produces wrong headers with utf8 enc.

[Barry A. Warsaw]

Barry A. Warsaw  added the comment:

This isn't a bug in Python, since it does the right thing by aliasing
'utf8' with 'utf-8'.  If this is incompatible with external mail tools,
then you should use 'utf-8' instead, but I don't think Python should
change that underneath you.

[issue5190] optparse doex not export make_option

[Bluebird]

New submission from Bluebird :

The documentation of optparse mentions make_option() as the standard way 
to create an option list:

For example, in the doc of python 2.5:


14.3.3.2 Populating the parser 

[...]
pass it an Option instance (as returned by make_option()) 

[...]

option_list = [
make_option("-f", "--filename",
action="store", type="string", dest="filename"),
make_option("-q", "--quiet",
action="store_false", dest="verbose"),
]


(make_option() is a factory function for creating Option instances; 
currently it is an alias for the Option constructor. A future version of 
optparse may split Option into several classes, and make_option() will 
pick the right class to instantiate. Do not instantiate Option 
directly.) 
===

However, make_option is not part of the function exported in the __all__ 
list of optparse. Strangely enough, this does not prevent to use 
make_option() in regular python scripts, but it does not work when 
packaging a python application, for example with pyinstaller.

The problem is also present in python 2.6

The fix is either to update the documentation to use Option() directly 
or to add make_option to __all__

[issue5191] Partial function application 'from the right'

[Ben North]

New submission from Ben North :

The functools module includes a 'partial' class, which allows partial
function application either by positional arguments or keyword
arguments.  However, it cannot be used to create, for example, a
function splitting a string on commas, or a function to extracts logs to
base 10.  I posted

   http://mail.python.org/pipermail/python-dev/2009-January/085638.html

which suggested a 'partial_right' feature, such that the following would
work:

   >>> import functools, math

   >>> split_comma = functools.partial_right(str.split, ',')
   >>> split_comma('a,b,c')
   ['a', 'b', 'c']

   >>> log_10 = functools.partial_right(math.log, 10.0)
   >>> log_10(100.0)
   2.0

There was some useful discussion, but generally the feeling was that the
extra complexity outweighed the potential benefits.  Also, chained
partial applications were troublesome.

The overlap in functionality between 'partial_right' and an existing
patch (#1706256) to allow skipping of positional arguments was raised.

I think the present issue should probably be closed/rejected, but it was
suggested on the mailing list that having the issue and patch on the
record might be useful.  Patches are against 2.6.1 source.

[issue4575] Py_IS_INFINITY defect causes test_cmath failure on x86

[Mark Dickinson]

Mark Dickinson  added the comment:

Fixed (I hope!) in the trunk in r69459.  I'll wait for buildbot results 
(just in case) and then merge to 2.6, 3.1 and 3.0.

The same test_cmath failure can also be seen on OS X 10.5.6/Intel when 
compiling with -fmpmath=387.  Annoyingly, the fix above doesn't work here:  
it seems that the OS X isinf is buggy.  It doesn't seem worth working 
around this bug though, since there's little sane reason to be compiling 
with -fmpmath=387 in the first place, so it's unlikely that any regular 
Python users will encounter this problem.

[issue4804] Python on Windows disables all C runtime library assertions

[Kristján Valur Jónsson]

Kristján Valur Jónsson  added the comment:

Ok, how about this comment, Martin?

/* Microsoft CRT in VS2005 and higher will verify that a filehandle is
 * valid and throw an assertion if it isn't.
 * Normally, an invalid fd is likely to be a C program error and 
therefore
 * an assertion can be useful, but it does contradict the POSIX standard
 * which for write(2) states:
 *"Otherwise, -1 shall be returned and errno set to indicate the 
error."
 *"[EBADF] The fildes argument is not a valid file descriptor open 
for
 * writing."
 * Furthermore, python allows the user to enter any old integer
 * as a fd and should merely raise a python exception on error.
 * The Microsoft CRT doesn't provide an official way to check for the
 * validity of a file descriptor, but we can emulate its internal 
behaviour
 * by using the exported __pinfo data member and knowledge of the 
 * internal structures involved.
 * The structures below must be updated for each version of visual 
studio
 * according to the file internal.h in the CRT source, until MS comes
 * up with a less hacky way to do this.
 * (all of this is to avoid globally modifying the CRT behaviour using
 * _set_invalid_parameter_handler() and _CrtSetReportMode())
 */

Also, I've added the following to fileobject.h, not coming up with a 
better place:

#if defined _MSC_VER && _MSC_VER >= 1400
/* A routine to check if a file descriptor is valid on Windows.  
Returns 0
 * and sets errno to EBADF if it isn't.  This is to avoid Assertions
 * from various functions in the Windows CRT beginning with
 * Visual Studio 2005
 */
int _PyVerify_fd(int fd);
#else
#define _PyVerify_fd(A) (1) /* dummy */
#endif

[issue5192] Update log message formatting.

New submission from David W. Lambert :

Allow logger object log message creation methods using ''.format method.

have:

logger_object.info('%s','lazy is better')
logger_object.debug('{0!s}'.format('wasted effort'))


want:

logger_object.debug('{0}','Lazy')


Work'rounds from pep282:

if log.isEnabledFor(logging.INFO):
hamletStr = hamletDom.toxml()
log.info(hamletStr)

or install custom Formatter.

I presume this is already on the back burner.


Incidentally, BufferingFormatter.format uses string += string instead of
''.join(list_of_strings).

[issue1818] Add named tuple reader to CSV module

[Raymond Hettinger]

Raymond Hettinger  added the comment:

Consider providing a hook to a function that converts non-conforming

I'm going to either post a recipe to do the renaming or provide a static
method for the same purpose.   It might work like this:

  ['abc', 'x_def', 'x_1', 'x_hidden', 'x_abc', 'p', 'x1_abc']

[issue5120] Disabling test_ttk_guionly on mac

[Guilherme Polo]

Guilherme Polo  added the comment:

The abort still happens occasionally, see:
http://www.python.org/dev/buildbot/all/OS%20X%20x86%20trunk/builds/118/step-test/0
(last lines)

I've talked with Daniel Steffen, who is one of the maintainers of Tcl/Tk
on Mac OSX, and I was told that all this conditional code in _tkinter.c
and tkappinit.c for TK_AQUA is outdated starting with tk 8.4.8, but tk
8.4.7 that ships with macosx (which happens to be the version being used
by the buildslave mentioned above) also includes the patch that
deprecates the usage, and we should be calling only Tk_Init on
tkappinit.c which will deal with all the details (the details are in
tkMacOSXInit:TkpInit).

There is an entry in tk's changelog that is directly related to this:
http://tktoolkit.cvs.sourceforge.net/viewvc/tktoolkit/tk/ChangeLog.2004?revision=1.1&view=markup
(lines 210-220)

Any chance I can change _tkinter and tkappinit to check for
TKINTER_OLD_AQUA (new macro to be added) instead of TK_AQUA and verify
if it helps the buildslaves ?

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

[Antoine Pitrou]

Antoine Pitrou  added the comment:

Besides the fact that this is probably great work, I really wonder who
will have enough time and skills to review such a huge patch... :-S

In any case, some recommendations:
- please provide patches against trunk; there is no way such big changes
will get committed against 2.6, which is in maintenance mode
- avoid, as far as possible, doing changes in style, whitespace or
indentation; this will make the patch slightly smaller or cleaner
- avoid C++-style comments (use /* ... */ instead)
- don't hesitate to add extensive comments and documentation about what
you've added

Once you think your patch is ready, you may post it to
http://codereview.appspot.com/, in the hope that it makes reviewing easier.

[issue5122] test_tcl and test_ttk_guionly don't like each other

[Eric Smith]

Eric Smith  added the comment:

The current patch (protect_tk_loading.diff) looks reasonable to me, and
it solves my problem with the tests hanging. So I'd suggest you commit
the patch, insofar it improves on the current situation.

I'm not an expert in tk, however. So if you're looking for advice from
someone knowledgeable on tk's inner workings, you'll need to get someone
else involved.

Roy Wood  added the comment:

This patch would be very useful to me, so I'm sad to see it's been
languishing for so long.  :-(

Is there any way to encourage the maintainer to merge this into the

[issue5019] Specifying common controls DLL in manifest

[Robin Dunn]

Robin Dunn  added the comment:

If I understand correctly then setting an activation context won't help
because by the time that an extension module is loaded the choice of
which version of the common controls DLL will be loaded has already been
made, and it may in fact already be loaded.  The system must be told at
the time that the .exe is loaded which common controls DLL it wants,
otherwise it will use the old non-themed version.  Everything I've tried
seems to confirm this, if that is not true I'd love to see some examples.

[issue500698] Taint a la Perl?

Daniel Diniz  added the comment:

"""
I found I needed support for taint mode in python and have done some
work to realise this. It's by no means complete at this time, but I'm
floating this idea on this group to see how much interest there is.

The implementation is pretty simple:

- an extra field in PyObject to maintain the taint status
- a couple of extra functions __gettaint__() that returns the taint
status and __settaint__(value) that sets the taint value, returning the
previous status
- an additional command-line flag -a and environment variable
PYTHONIGNORETAINT that suppress taint checking
- a few macros defined in Objects/object.h to support taint management
- a new built-in exception, PyExc_TaintError, for reporting operations
on tainted objects

[issue5019] Specifying common controls DLL in manifest

[Robin Dunn]

Robin Dunn  added the comment:

Ok, the following files will be attached:

python.exe.manifest: This is a copy of the manifest resource that I put
into the 2.6.1 python.exe file by hand for testing.  The original
manifest was the same but without the 2nd ...
group.

sample.py: the simple little sample I used to make the screenshots.

Snap001,png: This is sample.py running with the original python.exe
running on Vista.  Notice the plain, flat, outdated and ugly win2k look
and style of the notebook tabs and buttons.

Snap002.png:  The same sample running with a modified python.exe.  Now
it has textures, gradients, mouse-over effects and etc. and will match
the look of other modern applications running on the machine that are
using the standard themes.

[issue1096310] sys.__stdout__ doco isn't discouraging enough

[Daniel Diniz]

Daniel Diniz  added the comment:

Current docs seem to explain what __stdout__ is for:
"""
__stdin__ / __stdout__ / __stderr__

These objects contain the original values of stdin, stderr and stdout at
the start of the program. They are used during finalization, and could
be useful to restore the actual files to known working file objects in
case they have been overwritten with a broken object.
"""

Should a note of warning be added? Something like:

Explicitly saving the original IO streams and restoring them after
redirection is safer and the recommended idiom.

[issue5019] Specifying common controls DLL in manifest

[Martin v. Löwis]

Martin v. Löwis  added the comment:

It looks like it should be possible to bind to a different comctl32.dll
than what gets loaded by the host application. See this KB article:

http://support.microsoft.com/default.aspx/kb/830033

which even claims that you should be able to do so with manifests
(notice how you need to define ISOLATION_AWARE_ENABLED to get different
versions of CreateWindowEx etc); also see the .NET code on how they use
explicit activation contexts 

Also see

http://blogs.msdn.com/junfeng/archive/2007/06/26/rt-manifest-resource-and-isolation-aware-enabled.aspx

for an explanation what resources must be defined so that a DLL can bind
to a different version than the rest of the process.

I think you want to put the comctl32 manifest binding into RT_MANIFEST
resource 2 (not 1, as you probably had tried so far).

[issue1103926] email.base64MIME.header_encode vs RFC 1522

[Daniel Diniz]

Daniel Diniz  added the comment:

RFC 2047 says the encoding is case-insensitive. Please, close as invalid.

RFC 2047:
2. Syntax of encoded-words

   An 'encoded-word' is defined by the following ABNF grammar.
[...]
   encoded-word = "=?" charset "?" encoding "?" encoded-text "?="
   charset = token; see section 3
   encoding = token   ; see section 4

[...]
   Both 'encoding' and 'charset' names are case-independent.  Thus the
   charset name "ISO-8859-1" is equivalent to "iso-8859-1", and the
   encoding named "Q" may be spelled either "Q" or "q".

[issue1112955] move_file()'s return value when dry_run=1 unclear

[Daniel Diniz]

Daniel Diniz  added the comment:

Here's a very simple-minded patch (with microtest) that changes behavior
in a questionable way.

If it goes in as-is, dry_run=1 will not always succeed anymore. So it'd
be incompatible... but a 1:1 representation of a real move kinda
requires some failure mode.

It's possible to avoid raising when dry_run=1, logging a warning that a
real move would fail, and return the imaginary new full name. Or return
None, '', etc. Suggestions?

Perhaps studying a use-case makes things clearer. 

Looks like copy_file already has the same return value independent of
dry_run.

[issue5194] OS X IDLE.app and bin/idle: missing/extra menu options

[Ned Deily]

New submission from Ned Deily :

IDLE is supposed to have various menu customizations when running on OS 
X. But currently they do not all work and the menus vary if IDLE is 
launched via IDLE.app versus via command line bin/idle.  The most 
noticeable issue is the lack of a Preferences menu item in IDLE.app to 
access the IDLE configuration settings.

ANALYSISThere are inconsistent OS X execution checks scattered
throughout idlelib.  Also, the bootstrap mechanism
for IDLE.app causes sys.executable to be set incorrectly.
Most importantly, idlemain imports idlelib before it
has fixed up the execution environment.  This can cause
the menu fixup in idlelib.Bindings to be skipped.

SOLUTIONChange idlemain to set up the execution environment
consistently and defer idlelib imports until it has done so.
Modify several OS X checks in idlelib for consistency.

APPLIES py3k, 3.0   -> patch-nad0014-py3k-30.txt
trunk, 2.6  -> patch-nad0014-trunk-26.txt

DELETE  Mac/IDLE/idlemain.py(py3k and 3.0 only!)

NOTEIn 3.x idlemain.py was copied down into the app bundle:
2.x -> Mac/IDLE/idlemain.py
3.x -> Mac/IDLE/IDLE.app/Contents/Resources/idlemain.py
3.x -> Mac/IDLE/idlemain.py  -> unused / delete
so there are two versions of this patch.
However, the 2.x location was not deleted in 3.x svn
so there are two identical files in 3.x prior to this
patch.

[issue5195] OS X IDLE.app and bin/idle: incorrect key defaults in 3.x

[Ned Deily]

New submission from Ned Deily :

3.x IDLE uses incorrect default key definitions on OS X

If you have not already customized your IDLE key definitions
(in ~/.idlerc), 3.x IDLE uses Windows defaults in its menus.

ANALYSISIn 2.x, the IDLE Makefile customized the default configs
in Lib/idlelib.  In 3.x there is no longer a separate
IDLE Makefile and the customization step is missing.

SOLUTIONAdd the OS X customization to the Mac/Makefile.

APPLIES py3k, 3.0

[issue5196] OS X IDLE.app: may not launch on 3.x

[Ned Deily]

New submission from Ned Deily :

3.x OS X IDLE.app may not launch

ANALYSIS 2.x IDLE.app was built using its own Makefile + bundlebuilder.
 For 3.x, these were eliminated by checking in a skeleton app
 based on the bundlebuilder model.  But the install tailoring
 of the app does not quite work in all cases.

SOLUTION Have the Mac/Makefile do the necessary tailoring.
 Remove from the IDLE launch script the unnecessary bits left
 over from bundlebuilder.

APPLIES  py3k, 3.0

SEE ALSO Issue5194 and Issue5195:
 patch-nad0014, patch-nad0015 (should be applied first)

[issue5143] OS X: Py_SetProgramName argument has type char*; should be wchar_t*

[Ned Deily]

Ned Deily  added the comment:

Here's the results of testing the two patches:
- patch-mbstowcs.txt should not do a free on the buffer since
  Py_SetProgramName is expecting to hold on to it (like with
  the result of a getenv(3)).
- patch-remove-PYTHONEXECUTABLE.txt works as is.

However, neither of these patches in and of themselves fix all
the issues with OS X IDLE menus on 3.x (most of the issues are
present in 2.x as well).  See Issue5194, Issue5195, and Issue5196.
In particular, the patches in 5194 and 5196 also eliminate the
dependence on PYTHONEXECUTABLE influencing sys.executable.

So, just looking at IDLE, it would not hurt to remove the
PYTHONEXECUTABLE magic. On the other hand, it is a documented
behavior of PYTHON:

http://docs.python.org/3.0/using/cmdline.html#envvar-PYTHONEXECUTABLE

and removing it *could* add extra problems for people porting
over bundlebuilder-based apps or for whatever other reason they
might be using it.

So my recommendation is to fix PYTHONEXECUTABLE.  Attached patch
patch-nad0013-py3k-30.txt does so.  It also includes a fix for 
another very similar OSX-only 2.x->3.x wchar_t conversion problem
which also causes an "incompatible pointer type" build warning,
something I noticed while investigating this.  The patch has been
tested on both py3k and 3.0.  patch-nad0013t-py3k-30.txt adds
a test case for PYTHONEXECUTABLE behavior.

[issue5019] Specifying common controls DLL in manifest

[Robin Dunn]

Robin Dunn  added the comment:

Sorry, no luck.  I've tried before to ensure that all the DLLs and
extension modules have the manifest file (in resource 2) and it makes no
difference.  I rebuilt wxWidgets and wxPython today with
ISOLATION_AWARE_ENABLED defined to check if that would help, and reset
the manifest resource in all the binaries, but it makes no difference.

[issue5197] vars() assignment fails silently when assignments made later

[pest]

New submission from pest :

Assignments to vars() behave incorrectly if those variables are use
later on in a function.

For example, try this:

==
#!/usr/bin/python

def zz():
for i in [1,2,3]:
for j in [4,5,6]:
vars()['fw_%s_%s' % (j,i)] = 'test %s %s' % (j, i)
print vars()['fw_%s_%s' % (j,i)]

fw_4_2 = 'zz'
print fw_4_2

zz()
==

The assignments work fine up till 4_2. At 4_2, the assignment apparently
fails silently, and the print raises a keyError exception.
