[issue17033] RPM spec file has old config_binsuffix value

[Nick Coghlan]

Nick Coghlan added the comment:

Do we even *use* the spec file in Misc/RPM for anything any more? Should we 
just delete the entire directory?

One lingering doubt I have is about how I throw the two new test case classes

[issue16817] test___all__ affects other tests by doing too much importing

[Eric Snow]

Eric Snow added the comment:

So the current solution is to temporarily put the relevant module in place in 
sys.modules, right?  That seems to be the solution that Stefan recommended and 
used in the decimal module.  Sounds good to me.

I'm hitting this while doing the PEP 399 two-step for the collections module.  
It seems like this will be a problem for testing any module that has had such 
attention and has __all__.  I'd be a fan of a class decorator that would take 
care of this and the rest of the PEP 399 stuff for you.

I've created issue #17037 to cover that (so it doesn't get muddled in with this 
discussion of test___all__).  There's even a proposed patch.

[issue17037] Add conforms_to_pep399() to test.support

[Eric Snow]

New submission from Eric Snow:

Related to issue #16817 and to my efforts on a C OrderedDict, I think it would 
be nice to have a class decorator that handles most of the PEP 399 requirements 
for you.  The attached patch adds such a decorator to test.support.

[issue16770] Selection in IDLE often skips first character

[Irwin Jungreis]

Irwin Jungreis added the comment:

I have reopened this issue because there are still cases where it does not 
work. I installed 8.5.13 and the IDLE patch as suggested. That fixed the 
particular case that I had used to demonstrate the problem (a file containing 
just two characters M1). However, the problem still occurs in other cases. To 
reproduce it, in IDLE pick File | New Window. In the new window type the 
characters '>>>from' (no spaces, and without the quotes). Now, before clicking 
anywhere else, move the cursor to the left half of the 'r'. Click once, and the 
insertion point incorrectly goes to the right of the 'r'. Click a second time 
without moving the cursor and the insertion point goes to the left side of the 
'r'. Unlike the previously reported case, repeated clicking does not cause it 
to alternate -- only the first click is wrong. I have attached a second video 
(IMG_1219.MOV) that demonstrates this.

[issue17036] Implementation of the PEP 433: Easier suppression of file descriptor inheritance

[STINNER Victor]

STINNER Victor added the comment:

I tested 9bdfa1a3ea8c.patch on Fedora 16 (Linux 3.6, glibc 2.14), Debian Etch 
(Linux 2.6.19), OpenBSD 5.2, OpenIndiana, FreeBSD 8.2, Windows 7.

I tested both cases (works/not supported) for O_CLOEXEC and SOCK_CLOEXEC. For 
the WSA_FLAG_NO_HANDLE_INHERIT flag, I only tested a Windows version not 
supporting it (Windows 7 SP1 is required).

I wouldn't bother with virtualenvs yet. First I'd simply install python
into /tmp:

mkdir /tmp/usr
./configure --prefix=/tmp/usr/
make
make install

Then always call python with the full path. If your app is a simple
script, then:

/tmp/usr/bin/python app.py

If you have to install it:

/tmp/usr/bin/python setup.py install

[issue16235] Add python-config.sh for use during cross compilation.

[Ray Donnelly]

Ray Donnelly added the comment:

Great. My only query is whether the changes to sed will work on non-GNU sed.

It used to be like:
sed < in >out

you've now got:
sed in >out

I'm not saying it won't work, I'm not in a position to check, but I think it's 
safer to keep it as it was.

[issue10156] Initialization of globals in unicodeobject.c

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

> The 2.7 comments also apply to the 3.2 patch. Otherwise the 3.2 patch
> (without the _sre changes :) looks good to me.

Patches updated addressing new Stefan's comments. Unicode globals no longer 
reinitialized in _PyUnicode_Init(). Note that I have added a consistency check 
into the macro in 3.3+.

I hope Rietveld will accept this set.

Did compile that version and it launches.
To test with my code i do not want to have it interfere with my current version.
I remember it is possible to setup n isolated environment with pip en 
virtualenv.
But i never did this so far.
Any hints / links to (simple) script explanation that could do the job?
Or is there an even simpler way?

You need to upload them individually and "submit changes" 3 times, but it's not 
necessary to write a comment every time.  Also, unless the 3 patches are 
independent, it's usually better to upload a single diff that includes all the 
necessary changes.

(In Mercurial, the only objects are changesets; hg log trawls through commit

I'm also quite sure that it's the same issue. It would be nice to have
confirmation though. If you have the opportunity to compile the tip of
the 2.7 branch (where #14591 is fixed), get one of these:

My program is sort of complex in the meaning of multiple processes interleaving 
and interacting via a priorityqueue.
Each individual steps through multiple classes which all should stay 
independent.
No simple short snippet.

[issue16235] Add python-config.sh for use during cross compilation.

[Matthias Klose]

Matthias Klose added the comment:

so here is what I intend to commit.

 - --help now does exit with 0 (same as the python script)
 - removed the abi safety check (always compares the same
   two strings)
 - build the script for the build target, so that it can be
   checked before installing it.
 - install the old script in $(LIBPL). Maybe we can remove
   this later, or add this functionality into sysconfig.

[issue17027] support for drag and drop of files to tkinter application

[Ned Deily]

Ned Deily added the comment:

A feature like drag-and-drop seems like something that needs to be provided at 
either the application level or within Tk or both.  While there is apparently 
no built-in Tk support for drag-and-drop, it appears to be possible to use a Tk 
extension that provides that capability and that will work with Tkinter.  See, 
for example,

Not an autotools expert, but patch looks good.  Apparently 3.3 is still open to 
such changes.

[issue17033] RPM spec file has old config_binsuffix value

[Taavi Burns]

New submission from Taavi Burns:

Looking at the Misc/RPM/python-X.X.spec files, they seem to be slightly out of 
date. Near the top of the file is a config_binsuffix configuration setting that 
is "2.6" for both the 2.7 and 3.3 branches!

I suspect that it should be updated with the version and libvers variables a 
bit later in the file.

[issue3871] cross and native build of python for mingw* hosts

[Matthias Klose]

Matthias Klose added the comment:

some random comments about py3k-20121004-MINGW.patch:

- Modules/_ctypes/libffi_msvc/win32.S
  Please can you get rid of libffi_msvc and use libffi?
  afaics, libffi has support for mingw32.

- there seem to be chunks which are unrelated to mingw, like:

@@ -830,15 +926,18 @@ class PyBuildExt(build_ext):
 if have_usable_openssl:
 # The _hashlib module wraps optimized implementations
 # of hash functions from the OpenSSL library.
+# NOTE: _hashlib require only OpenSSL crypto library !
 exts.append( Extension('_hashlib', ['_hashopenssl.c'],
depends = ['hashlib.h'],
include_dirs = ssl_incs,
library_dirs = ssl_libs,
-   libraries = ['ssl', 'crypto']) )
+   libraries = ['crypto']) )

please file separate issues.


- why setup_info.in. looks like something which could be done with 
get_config_var.

- why re-reading files in setup.py, and grepping these for config options?


I think the patch would benefit from splitting it up into several 
self-contained chunks.

did you try to do builds for windows and linux after this patch was applied?

[issue3754] cross-compilation support for python build

[Matthias Klose]

Matthias Klose added the comment:

about py3k-20121004-CROSS.tgz:

- committed 0001-CROSS-fix-typo-in-thread-AC_CACHE_VAL.patch

- 0002-CROSS-restore-graminit.-to-source-directory.patch
  is this necessary?  Assuming that you have correct time
  stamps, this is something which usually is not built during
  a cross build.

  Can we just have a shell script which touches some files
  so that you can cross-build even from the repository without
  building pgen?

  Do the release managers have such a script which is run
  when building a release?

- 0003-CROSS-restore-importlib-header-to-source-directory-a.patch

  Same as for 0002, using correct timestamps. The EXEEXT is a
  different issue. However I'm not sure what to use, EXEEXT,
  or BUILDEXEEXT.

- 0004-CROSS-restore-AST-to-source-directory.patch

  Same as for 0002. Btw, does this fail with a native out-of-tree
  build too?

- 0005-CROSS-revert-issue13150-i.e.-python-solution-with-_s.patch
  A comment like "The fix for issue #13150 is bogus and break
  everything" might not the best way to convince maintainers ...

  This works for me, and IMO should be dropped, or please explain
  why this doesn't work for you.

- 0006-CROSS-initialise-include-and-library-paths.patch
  Afaics, a similar patch is now applied. Can be dropped.

- 0007-CROSS-set-_PYTHON_PROJECT_BASE-to-current-build-dir.patch
  Applied.

- 0008-CROSS-use-_PYTHON_PROJECT_BASE-in-distutils-sysconfi.patch
  Applied.

- 0009-CROSS-pass-all-top-configure-arguments-to-libffi-con.patch

  Why is it needed to pass all configure args?

- 0010-CROSS-warn-only-if-readelf-is-not-in-host-triplet-fo.patch

  Why is this needed just for readelf? If you do have a cross
  toolchain installed, then this should be available with
  the triplet name, same as for gcc, as, ...

- 0011-CROSS-append-gcc-library-search-paths-instead-to-pre.patch

  Looks ok. Could you mention where this does make a difference,
  or do you just want to keep the search order as defined by
  the compiler?

- 0012-CROSS-avoid-ncursesw-include-path-hack.patch

  This would break cross-building in a multiarch environment.
  Maybe we need a --with-curses-incdir=<> option.

- 0013-CROSS-properly-detect-WINDOW-_flags-for-different-nc.patch
  This should be a separate issue. Not cross specific.

- 0014-CROSS-use-build-directory-as-root-for-regression-tes.patch
  why is this necessary?

- 0015-CROSS-test-tools-has-to-depend-only-from-location-of.patch
  Looks ok, but not cross specific. Could you file a separate issue?

- 0016-CROSS-reload-may-fail-with-operation-on-closed-file-.patch
  Looks like a separate issue.

[issue17032] Misleading error message: global name 'X' is not defined

[Ram Rachum]

New submission from Ram Rachum:

Every single time I see the error message `global name 'X' is not defined` I 
say to myself, "ah yeah, I mistyped a variable name."

But then it occurred to me, why should I have to do this mental translation 
from "global name not defined" to "I mistyped a variable name"?

Now, I'm not asking for the error message to say "You mistyped a variable 
name", because that goes too much into second-guessing the user. But can we at 
least drop the reference to a global name? I understand that Python first 
searches the local namespace, and only then in the global namespace, and if the 
name isn't found there then an error is raised. But that doesn't mean that the 
error message should just assume that the variable is supposed to be global. 
It's misleading to say that a variable is global when it's in fact local.

I think that the error message should just say `Variable 'X' not defined`. 
Maybe add a suggestion `(Typo?)` at the end.


Example:

>>> def f():
... meow = 0
... return meoow
...
>>> f()
Traceback (most recent call last):
  File "", line 1, in 
  File "", line 3, in f
NameError: global name 'meoow' is not defined

I'd make the error message:

NameError: Variable 'meoow' is not defined

[issue8478] tokenize.untokenize first token missing failure case

[Thomas Kluyver]

Thomas Kluyver added the comment:

#16224 appears to be a duplicate.

There seem to be several quite major issues with untokenize - see also #12691 - 
with patches made to fix them. Is there anything I can do to help push these 
forwards?

[issue17031] fix running regen in cross builds

[Matthias Klose]

New submission from Matthias Klose:

currently regen calls the python interpreter for the host, not the build 
machine. You can't directly use BUILD_FOR_PYTHON, because this one uses 
./python explicitly, so use BUILDPYTHON instead.

I'd like to see this for 3.3 and the trunk.

Matthias Klose added the comment:

in 3.3 and later, the test defaults to no when cross-building. If gcc is used 
for the cross build, then a compile test is used. 

it is usually needed to provide some values in a CONFIG_SITE file. See autoconf
