[issue12702] shutil.copytree() should use os.lutimes() to copy the metadata of symlinks

[Petri Lehtinen]

New submission from Petri Lehtinen :

As discussed in issue 12183, shutil.copytree(..., symlinks=True) should copy 
the metadata of symlinks instead of the metadata of the file that the symlink 
refers to.

This can be achieved by using os.lstat() and os.lutimes() (new in 3.3) on 
symlinks.

[issue12682] Meaning of 'accepted' resolution as documented in devguide

Ditto.

Having separate resolutions for bugs and features makes it harder to
find all issues that have been closed as "bug fixed or feature
accepted", because you cannot select multiple resolutions when
searching.

With one resolution, you can simply search for "fixed" issues. If you
only want to find feature requests that were accepted, search for
type=feature and resolution=fixed.

[issue12646] zlib.Decompress.decompress/flush do not raise any exceptions when given truncated input streams

[Oleg Oshmyan]

Oleg Oshmyan  added the comment:

I have another proposition (as an alternative). The new _bz2.BZ2Decompressor 
objects have an attribute called eof which is False until the end of the stream 
is read. The same attribute could be added to zlib.Decompress objects.

[issue12687] Python 3.2 fails to load protocol 0 pickle

[Andrew Wilkins]

Andrew Wilkins  added the comment:

In _pickle.c, the load_put function calls _Unpickler_Readline, which may 
prefetch data and place it after the line read in with "readline". load_put 
then calls PyLong_FromString, which doesn't like the trailing data after the 
'\n'.

Maybe just use PyOS_strtol instead? Alternatively, replace the newline with a 
null byte.

[issue12701] Apple's clang 2.1 (xcode 4.1, OSX 10.7) optimizer miscompiles intobject.c

[deadshort]

New submission from deadshort :

Apple Radar ticket 9908625 has been filed. The clang 2.1 optimizer causes 
overflows in Object/intobject.c:int_pow() to be missed, so 2**63 turns into a 
negative integer. The attached test program narrows it down. llvm-gcc is fine, 
so this ticket is mostly an FYI.

idiotbox:Python-2.7.2 cloomis$ ./seqpoint-OK 40 40
a=40, b=40, c(a*b)=-2446744073709551616, c/b=-611686018
overflow detected: 1

  to turn into:

idiotbox:Python-2.7.2 cloomis$ ./seqpoint 4294967296 42
a=4294967296, b=42, c(a*b)=-407881430509551616, c/b=4294967296

[issue12691] tokenize.untokenize is broken

[Gareth Rees]

Gareth Rees  added the comment:

Please find attached a patch containing four bug fixes for untokenize():

* untokenize() now always returns a bytes object, defaulting to UTF-8 if no 
ENCODING token is found (previously it returned a string in this case).
* In compatibility mode, untokenize() successfully processes all tokens from an 
iterator (previously it discarded the first token).
* In full mode, untokenize() now returns successfully (previously it asserted).
* In full mode, untokenize() successfully processes tokens that were separated 
by a backslashed newline in the original source (previously it ran these tokens 
together).

In addition, I've added some unit tests:

* Test case for backslashed newline.
* Test case for missing ENCODING token.
* roundtrip() tests both modes of untokenize() (previously it just tested 
compatibility mode).

and updated the documentation:

* Update the docstring for untokenize to better describe its actual behaviour, 
and remove the false claim "Untokenized source will match input source 
exactly". (We can restore this claim if we ever fix tokenize/untokenize so that 
it's true.)
* Update the documentation for untokenize in tokenize.rdt to match the 
docstring.

I welcome review: this is my first proper patch to Python.

[Martin von Gagern]

Martin von Gagern  added the comment:

The server continues all right. It's the browser window which displays the 
error message. Not much better in my opinion, though.

To be completely accurate: currently the -b option doens't work as it should 
due to issue #11432. But using "-p 0" and opening the link manually is a 
suitable workaround for now.

Brandon, thanks for your work on this patch! I've just committed the unittests

For the remaining part, I see that Nick and you worked on it during a sprint,

fill in the missing bits.

re coverage: I saw the other issue, but I didn't connect the dots, thanks for

[issue12675] tokenize module happily tokenizes code with syntax errors

Gareth Rees  added the comment:

Terry: agreed. Does anyone actually use this module? Does anyone know what the 
design goals are for tokenize? If someone can tell me, I'll do my best to make 
it meet them.

Meanwhile, here's another bug. Each character of trailing whitespace is 
tokenized as an ERRORTOKEN.

[issue12662] Add support for duplicate options in configparser

[Łukasz Langa]

Łukasz Langa  added the comment:

This specific config format you're discussing strikes me as error prone and 
barely useful. With the use case you've given I cannot justify introducing 
support for it in the standard library. Remember that each switch, variant, 
however obscure and rarely used, increases source code complexity and 
introduces a maintenance burden.

As you've seen with the freshly introduced `strict` option, we're generally 
heading the other direction: to let application users know early they 
potentially made a misconfiguration that could confuse them later on.

So, thanks for your feedback but unfortunately I will have to say no to that 
proposal.

[issue12691] tokenize.untokenize is broken

[Gareth Rees]

Gareth Rees  added the comment:

I think I can make these changes independently and issue two patches, one 
fixing the problems with untokenize listed here, and another improving tokenize.

I've just noticed a third bug in untokenize: in full mode, it doesn't handle 
backslash-continued lines correctly.

[issue12690] Tix bug 2643483

[Gary Levin]

Gary Levin  added the comment:

Terry, I am just a new casual user.

The fix described in the Tix report (adding the '-') fixed the problem for me.  
But the report (2009-02-26) is after the most recent Tix build (8.4.3   
2008-03-17).  I don't know if it was ever added to the repository.   

Is Tix still being supported?  No, the last CVS change was FileEnt.tcl revision 
1.7 by hobbs, Sun Mar 28 02:44:57 2004.  Looks pretty dead to me.

If not, a good reason for me to skip Tix and use tkinter and ttk.  There have 
been recent commits (last commit on 2011-06-30).

[issue12696] pydoc error page due to lacking permissions on ./*

[Terry J. Reedy]

Terry J. Reedy  added the comment:

Do any of you three have anything to do with pydoc?

Given that the manual simply says "pydoc -b will start the server and 
additionally open a web browser to a module index page." without 
qualifications, quitting when started from certain locations strikes me as a 
bug.  I do not see a reason to not just continue.

[issue12662] Add support for duplicate options in configparser

[Brian Curtin]

Brian Curtin  added the comment:

This would break existing config files, including some of my own. 

It would also require that you have some end delimiter on every item in order 
to handle the event that someone duplicates options, otherwise the following 
would likely behave badly in your application

[sect]
opt=first
opt=second

This would give you "firstsecond" that you'd somehow need to parse. Sometimes 
if I'm testing out options, like I want to check how "second" works, I'll 
quickly just do it as above. With a change like this, I couldn't do that, I'd 
be forced to comment out the first line, or add a delimiter and split on it.

I'm pretty sure this was intentional.  It is analogous to Skip messages

[issue12540] "Restart Shell" command leaves pythonw.exe processes running

[Terry J. Reedy]

Terry J. Reedy  added the comment:

The replacement file, for anyone without a dev setup, is
http://hg.python.org/cpython/file/cc86f4ca5020/Lib/idlelib/PyShell.py

After renaming PyShell to PyShellBak and replacing with the above,
IDLE seems to run better than ever. On my XP system, the several second delay 
for the old process dying is gone and I never see 3 pythonw processes, even 
temporarily, as before. I can no longer tell from TaskManager that one process 
has been killed and another started. Testing included running tk windows. Will 
test later on new Win7 system.

Pending some unforeseen new problem, thank you Ned and Eli.

[issue12641] Remove -mno-cygwin from distutils

[Jon]

Jon  added the comment:

shortly after opening this issue i removed -mno-cygwin from my 2.7.2 install 
and have had no issues on win7 32bit. but i understand you're hesitation.

regardless what you decide, please consider placing a summary note in the 
source comments as a safety net.

if you'd like me to try building a limited set of extensions to help with your 
decision, let me know.  i have the following mingw toolchains on my win7 32bit 
system:

* tdm gcc 4.5.2 - http://tdm-gcc.tdragon.net/
* mingw-w64 prefix-stripped gcc 4.5.4 - 
http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win32/Automated%20Builds/
* Ruben's gcc 4.6.2 personal build - 
http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win32/Personal%20Builds/rubenvb/4.6.2-1/

i'm not speaking for Ruben, but as he maintains 
https://github.com/rubenvb/MinGW-w64-build-scripts you might try cajoling him 
if you feel you need more test results ;)

re: re.search, understood, thanks...quick-testing.

[issue12641] Remove -mno-cygwin from distutils

[Éric Araujo]

Éric Araujo  added the comment:

The necessity of walking on eggs with the distutils codebase restrains me.  
I’ve read the thread on sourceforge (thanks Ruben) but don’t have enough 
information yet to decide whether to do a version check, call gcc -dumpspecs or 
remove the option altogether.

BTW, there’s no need to use re.search if you’re not using a regular expression: 
“'no-cygwin' in output” will work.

[issue12326] Linux 3: code should avoid using sys.platform == 'linux2'

[James Y Knight]

James Y Knight  added the comment:

Oh wow, so it depends on the *build* time major version? That's really not 
useful at all for linux 2.x and 3.x; there is nothing useful anyone can 
possibly do with the distinction between platform == "linux2" and platform == 
"linux3". All it could possibly do is to break apps.

Given that:
a) old versions of Python won't even build without a patch and
b) changing platform to linux3 will break a lot of python apps that check 
sys.platform. 
c) It's completely useless to change it, as the change contains no actual 
information.

Why is forcing sys.platform to remain linux2 not the *obviously right thing to 
do*?

[issue12696] pydoc error page due to lacking permissions on ./*

[Martin von Gagern]

New submission from Martin von Gagern :

I'd like to be able to run "pydoc -b" in whatever directory I'm currently in. 
Most of the time that would be the root of my home directory, which is an 
ext4fs mount. So it has a subdirectory called "lost+found" for which I don't 
have any access permissions. As a result, the main pydoc info page will simply 
print an error message:

OSError: [Errno 13] Permission denied: './lost+found'

I'm not sure how best to address this. There are several possibilities that 
come to my mind:

 1. Provide a command line switch to strip '.' from sys.path.
 2. Skip any sys.path elements which cause exceptions, possibly
printing a warning in addition to the remaining page content.
 3. Skip any single subdirectry which causes an exception,
as this more closely models what importing by name would do.
 4. Explicitely skip lost+found, or perhaps any directory name which
would be invalid as a module name.

Obviously, the workaround is to change to a sufficiently empty directory before 
starting pydoc. So this is a minor issue, but annoying nevertheless.

[issue10570] curses.tigetstr() returns bytes, but curses.tparm() expects a string

[Tobias Klausmann]

Tobias Klausmann  added the comment:

This bug is still not fixed and basically makes the curses module unusable 
except for very narrow use cases. Unfortunately, my C-fu is very weak, 
otherwise I'd try to make a patch.

Tested this on Windows XP with Python 3.2 installed into "Program Files".
Works fine (including shell restart).

It would be great to get more people to test it though, especially people
who ran into the problem originally - Peter? Terry? Anish? Qiang Sun?

[issue12693] test.support.transient_internet prints to stderr when verbose is false

[R. David Murray]

R. David Murray  added the comment:

I'm pretty sure this was intentional.  It is analogous to Skip messages and the 
messages issued when a resource hasn't been enabled, which also print when 
verbose is not true: the test wasn't run, and it lets you know why.

[issue12695] subprocess.Popen: OSError: [Errno 9] Bad file descriptor

[Martin von Gagern]

Martin von Gagern  added the comment:

Sorry, this is a duplicate of issue #11432. Failed to find that, and also 
failed to realize that python is now using hg and my svn checkout might be 
outdated. Sorry there.

[issue12695] subprocess.Popen: OSError: [Errno 9] Bad file descriptor

[Martin von Gagern]

New submission from Martin von Gagern :

suprocess.Popen on POSIX (using _posixsubprocess Module) has a good chance of 
repeatedly closing the same file descriptor if the descriptor for stdin is also 
used for stdout and/or stderr. Only stdout and stderr are checked for equality 
with one another.

This breaks webbrowser.open for me, as the browser remote has all three 
descriptors redirected from/to /dev/null. This breaks "pydoc -p". I've taken 
this scenario and turned it into a unit test, which you find attached together 
with a proposed fix.

On my currently installed Python 3.2, the unit tests results in this traceback 
(and two more like it for other test classes):

ERROR: test_inouterr_fileobj (__main__.ProcessTestCase)

[issue12680] cPickle.loads is not thread safe due to non-thread-safe imports

[Antoine Pitrou]

Antoine Pitrou  added the comment:

> PyImport_ExecCodeModuleEx adds the module to sys.modules *before*
> actually executing the code. This is a design flaw (can it really be
> changed? )

I guess it is done so to allow for circular imports.

> The second bug: in cPickle.c: func_class() 
> cPickle 'manually' checks if a module is in sys.modules instead of

I would guess it is an optimization shortcut. A solution (while keeping the 
optimization) would be to take the import lock before checking sys.modules.

Note that the _pickle module in 3.x has the same kind of logic, and therefore 
probably the same issue too (haven't tested).
