[issue10089] Add support for arbitrary -X options

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc  added the comment:

Why wouldn't they? A standard way to extend the command line options seems 
useful in all environments.
Now the interpretation of these options are subject to variations of course...

Docs should be updated too. I see that the values could either be True
or a string? Would this be perceived as a limitation?

[issue10098] intermittent failure in test_os

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc  added the comment:

_kill_with_event() does not wait for the subprocess to be ready.
It seems to me that the following test is wrong:
if m[0] == 0:
It should be "if m[0] == 1", since we want to check that the subprocess updated 
the shared memory.

[issue10089] Add support for arbitrary -X options

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc  added the comment:

Well, the syntax allows to pass either a string value (because it's a substring 
of the command line), or nothing.

When no value is passed, True seems better than None, because this allows the 
usage of the get() method::
x = sys.xoptions.get('a')
or::
if sys.xoptions.get('a'):
this returns None if the option was not set, True if set to a empty value, and 
a non-empty string if set to an actual value.

[issue10099] socket.fromfd() documentation problem

[Senthil Kumaran]

Senthil Kumaran  added the comment:

I think, the original docs *is* pretty intuitive. It says "Duplicate the file 
descriptor fd and build a socket object".  No one will think that the this 
method will close the original fd. Person using this method might of course, 
explicitly close the original fd in some other part of the code (as he may use 
it after creating the socket object too).

If at all anything is required, a line may be "The original file descriptor is 
unaffected", but again that seems redundant to me.

[issue10089] Add support for arbitrary -X options

[Nick Coghlan]

Nick Coghlan  added the comment:

I suggest using sys._xoptions to make it clearer that this is for CPython 
specific internal implementation runtime tweaks. We're putting it in sys so 
*we* can get at it, not applications.

(It also makes it clear that other implementations aren't obliged to implement 
*any* particular interface to the -X options. Requiring that would go against 
the whole spirit of -X)

[issue10099] socket.fromfd() documentation problem

[Gergely Kálmán]

Gergely Kálmán  added the comment:

You are perfectly right, the docs are pretty clear. Although fromfd means (or 
at least to me) to "attach object to fd" and not "duplicate then attach to the 
duplicate". If someone forgets this particular behaviour and thinks that the 
function works as the name implies they're in trouble.

[issue10112] Use -Wl, --dynamic-list=x.list, not -Xlinker -export-dynamic

[Jan Kratochvil]

New submission from Jan Kratochvil :

FSF GDB (and future Fedora GDBs) became 250KB smaller than before.  Python 
recently disabled this GDB build optimization so GDB is 250KB larger again.

-rwxr-xr-x 1 4524488 gdb-7.1-19.fc13.x86_64/usr/bin/gdb
-rwxr-xr-x 1 4266728 gdb-7.1-19dynamiclist.fc13.x86_64/usr/bin/gdb
-rw-r--r-- 1 2364656 gdb-7.1-19.fc13.x86_64.rpm
-rw-r--r-- 1 2274300 gdb-7.1-19dynamiclist.fc13.x86_64.rpm

Some Python binaries/libraries could probably also benefit from smaller 
pageable code image.

GDB regressed due to /usr/lib*/python*/config/Makefile contains:
  LINKFORSHARED=-Xlinker -export-dynamic

and GDB thus has to use it even for its own link, effectively disabling its:
  -Wl,--dynamic-list=./proc-service.list

AFAIK Python already contains the required exports list but it is used only on 
MS-Windows.  It should be utilized even for GNU/Linux builds.

[issue10113] UnicodeDecodeError in mimetypes.guess_type on Windows

[Vladimir Dmitriev]

New submission from Vladimir Dmitriev :

Windows 7, Python 2.7

Some windows applications (QuickTime) add content-types to Windows registry 
with non-ascii names. mimetypes in unaware of that and fails with 
UnicodeDecodeError:

>>> mimetypes.guess_type('test.js')
Traceback (most recent call last):
  File "", line 1, in 
  File "c:\Python27\lib\mimetypes.py", line 294, in guess_type
init()
  File "c:\Python27\lib\mimetypes.py", line 355, in init
db.read_windows_registry()
  File "c:\Python27\lib\mimetypes.py", line 260, in read_windows_registry
for ctype in enum_types(mimedb):
  File "c:\Python27\lib\mimetypes.py", line 250, in enum_types
ctype = ctype.encode(default_encoding) # omit in 3.x!
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe0 in position 0: ordinal 
not in range(128)

Example registry leaf is attached to previous message.

I believe the correct behavior would be either to wrap UnicodeDecodeError 
exception and skip those content-typer or use .decode() method for registry 
keys and get encoding using locale.getdefaultlocale()

[issue9980] str(float) failure

[Kiriakos Vlahos]

Kiriakos Vlahos  added the comment:

I would like to say that these are two separate issues.  One is about the 
precision flag and the second about the exception masking flags of the FPU 
control words. Both issues affect a wider number of users than Python embedders 
using Delphi. For example C# uses 80 bit precision if I understand 
http://blogs.msdn.com/b/davidnotario/archive/2005/08/08/449092.aspx well.

Also both issues are primarily documentation issues.  If Python libraries make 
certain assumptions about the state of the FPU control word, these assumptions 
should be documented and users can then accommodate them.

[issue10114] compile() doesn't support the PEP 383 (surrogates)

[STINNER Victor]

New submission from STINNER Victor :

Example:

$ ./python
Python 3.2a3+ (py3k, Oct 15 2010, 14:31:59)

...
UnicodeEncodeError: 'utf-8' codec can't encode character '\udc80' in position 
3: surrogates not allowed

Attached patch encodes manually the filename to utf-8 with surrogateescape.

I found this problem while testing Python with an ASCII locale encoding (LANG=C 
./python Lib/test/regrtest.py). Example:

  $ LANG=C ./python -m base64 -e setup.py 
  ...
  UnicodeEncodeError: 'utf-8' codec can't encode character '\udcc3' ...

The problem is defining what does "such an environment" mean. It is
not necessarily Delphi, as this can happen whenever the FPU control
word is changed by an embedding application.
Kiriakos makes a good point. The underlying issue is that Python make
certain assumptions about the FPU control words, and there are
probably other global assumptions lurking elsewhere.
As I see it, the easiest solution is to document these assumptions as
and when they are found. Then it becomes the responsibility of the
hosting application to satisfy them.
Delphi already has to accomodate Python C heritage, for example by
defining functions used from Python with the C calling convention.
This would be just one more thing to remember, and in fact can be done
inside the Python4Delphi libraries once the Python behaviour is
defined and documented.

Also, banning floating-point operations is not a solution in my
opinion because Python libraries (standard and external) do not have
such a distinction. So an unknown of unexpected libraries (like json)
would break. And large parts of Python functionality wouldn't be
available.

Technically they are, yes. But they are both affected by any solution
that would incorporate preserving or documenting the FPU control word
for embedding applications. May be I should have opened a new issue.

[issue10115] accept4 can fail with errno 90

[Antoine Pitrou]

New submission from Antoine Pitrou :

When a machine has a newer glibc and an old kernel, accept4 can fail and then 
Python accept() is unusable. For example:

Traceback (most recent call last):
  File 
"/home/pybot/buildarea-sid/3.x.klose-debian-sparc/build/Lib/threading.py", line 
525, in _bootstrap_inner
self.run()
  File 
"/home/pybot/buildarea-sid/3.x.klose-debian-sparc/build/Lib/test/test_asynchat.py",
 line 37, in run
conn, client = self.sock.accept()
  File "/home/pybot/buildarea-sid/3.x.klose-debian-sparc/build/Lib/socket.py", 
line 132, in accept
fd, addr = self._accept()
socket.error: [Errno 90] Function not implemented

(from 
http://www.python.org/dev/buildbot/builders/sparc%20Debian%203.x/builds/147/steps/test/logs/stdio
 )


Improving our configure check wouldn't do a lot of good, since people can reuse 
Python binaries with different kernels. Perhaps we have to use some kind of 
runtime fallback.

(Strangely, errno 90 is EMSGSIZE here, and ENOSYS is 38)

[issue10116] Sporadic failures in test_urllibnet

[Stephen Hansen]

New submission from Stephen Hansen :

Ever since running the snow leopard buildslave, I've had sporadic failures in 
test_urllibnet. At first I thought it was just a net glitch on my machine or 
something, as immediately re-running the tests made it go away: but this most 
recent one:

http://www.python.org/dev//buildbot/builders/x86%20Snow%20Leopard%203.1/builds/20/steps/test/logs/stdio

happened while I was very much monitoring and using the network on the machine 
for other purposes, and everything was fine in general.

So, I went and looked into test_urllibnet to try to figure out why, and I 
notice that some of the tests use code to retry on IOErrors, and some don't-- 
and this test that failed in particular is one that doesn't. 

So: anyone have a better idea of what's going wrong, or is it just that hey, 
the active network tests are a bit flaky and all should use _open_with_retry 
instead of just some as is the case now?

[If the latter, I can do a patch]

FWIW, I've only seen this on the 3.1 and 3.x buildslaves, but have seen it on 
both of those more then once. But I don't know that its a 3.x specific issue: 
those builds get run more often then the 2.7 one, so have more chances to run 
into a sporadic issue.

precision, but I'm fairly sure that (as is almost always true in a Windows 
environment, except if you're using Delphi, apparently) the FPU precision is 
still set to 53-bit precision.

> if I understand 
> http://blogs.msdn.com/b/davidnotario/archive/2005/08/08/449092.aspx well.

And that article explicitly confirms the use of 53-bit precision:

"Precision is set by default in VC++ and CLR apps to ‘double precision’, which 
means that if you are operating with operands of type float, results of 
operations done with floats actually exist in the x87 stack as if there were of 
type double. In fact, it’s even weirder than that. They will have the mantissa 
of a double, but the range (exponent) of an extended double (80 bit)."

i.e., it's using the x87 FPU with precision set to 53 bits.

[issue10116] Sporadic failures in test_urllibnet

[Antoine Pitrou]

Antoine Pitrou  added the comment:

Rather than the hand-made _open_with_retry, I think it would be better to use 
support.transient_internet() (it's already used in other tests). Retrying is 
not very helpful if the other end is down.

Also, EBADF (bad file descriptor) looks like a bug. httplib should not use 
closed/non-existent file descriptors.

[issue10107] Quitting IDLE on Mac doesn't save unsaved code

[Ronald Oussoren]

Ronald Oussoren  added the comment:

Kevin, 

which versions of Tk does this work with?

IDLE should at least work with the versions of Tk 8.4 and 8.5 that Apple ships 
with OSX 10.4, 10.5 and 10.6 (the last one being the only one with built-in 
support for Tk 8.5)

[issue10107] Quitting IDLE on Mac doesn't save unsaved code

[Tal Einat]

Tal Einat  added the comment:

Note that some discussion about this issue is taking place on the idle-dev 
mailing list.

Bruce Sherwood found the line "root.bind('<>', 
flist.close_all_callback)", which seems to be an unsuccessful attempt to 
achieve the wanted behavior.

Kevin Walzer mentioned that a grep on the idlelib code doesn't turn up any 
references to "tk::mac::Quit".

I don't have access to OSX for testing. Could someone please replace the 
root.bind call with what Kevin suggested, and see if it solves the problem?

[issue10107] Quitting IDLE on Mac doesn't save unsaved code

[Ned Deily]

Ned Deily  added the comment:

It looks like the '::tk::mac::Quit' callback does not exist in the 
Apple-supplied Tk 8.4.7 in OS X 10.5 and 10.4, although it does work with the 
Apple-supplied Tk 8.4.19(?) and 8.5 in 10.6 and with a current ActiveState 
8.4.19 on 10.4 through 10.6.  However, instead of that, it looks like 
overriding the 'exit' callback will work fine on all of them.  In a simple 
test, I'm able to intercept the Tk app quitting, post a yes/no message, and 
then terminate the Tk app by destroying the root.  Next I'll try integrating 
into IDLE.

[issue5150] IDLE to support reindent.py

[Éric Araujo]

Éric Araujo  added the comment:

reindent.py is very much a script: It lacks a nice, full programmatic API, I 
mean standalone functions to check a file object or a filename and functions 
implementing the command-line interface.  As it is now, you see for example 
print calls in the middle of functions, so it’s not usable as a module.

Maybe bring this to python-dev or -ideas?

[issue9377] socket, PEP 383: Mishandling of non-ASCII bytes in host/domain names

[David Watson]

David Watson  added the comment:

> As a further note: I think socket.gethostname() is a special case, since this 
> is just about a local setting (i.e. not related to DNS).

But the hostname *is* commonly intended to be looked up in the
DNS or whatever name resolution mechanisms are used locally -
socket.getfqdn(), for instance, works by looking up the result
using gethostbyaddr() (actually the C function getaddrinfo(),
followed by gethostbyaddr()).  So I don't see the rationale for
treating it differently from the results of gethostbyaddr(),
getnameinfo(), etc.

POSIX says of the name lookup functions that "in many cases" they
are implemented by the Domain Name System, not that they always
are, so a name intended for lookup need not be ASCII-only either.

> We should then assume that it is encoded in the locale encoding (in 
> particular, that it is encoded in mbcs on Windows).

I can see the point of returning the characters that were
intended, but code that looked up the returned name would then
have to be changed to re-encode it to bytes to avoid the
round-tripping issue when non-ASCII characters are returned.

[issue9317] Incorrect coverage file from trace test_pickle.py

[Alexander Belopolsky]

Alexander Belopolsky  added the comment:

I have found the cause of at least part of the issue.  Apparently, module level 
statements for some of the modules such as pickle do not show up in trace 
because they are imported by trace itself.  In other words, by the time traced 
script gets executed, pickle is already in sys.module and the code therein does 
not run.

Maybe we should consider clearing sys.modules in Trace.run, but this can cause 
problems if not done carefully.

[issue7140] imp.new_module does not function correctly if the module is returned from a function and used directly

[Terry J. Reedy]

Terry J. Reedy  added the comment:

Since that revision only touched py3k, I am guessing that it only broke 3.2.

[issue9778] Make hash values the same width as a pointer (or Py_ssize_t)

[Skip Montanaro]

Skip Montanaro  added the comment:

Not that anybody needs my input on this, but...

Given the range of people advocating for this change, this looks to me
like it should be a release blocker for 3.2.  Raymond's comment about
performance seems especially important, and since the world seems to
be moving toward 64-bit operating systems (certainly should happen in
a big way during the lifetime of Python 3) it seems worthwhile to hold
up further 3.2 releases until this is solved.

[issue10058] Unclear PyString_AsStringAndSize return value

[Terry J. Reedy]

Terry J. Reedy  added the comment:

I am not much familiar with the C api but I presume that all functions return 
-1 on error and that this is documented somewhere in the beginning. I also 
presume that functions that return values thru passed in pointers and that are 
documented as returning an integer type return 0 on success. And ditto on some 
general note somewhere. I do not think that such should be repeated for each 
function. So without further justification, I would be inclined to close this.

The unnamed quasi-html file loaded with msg118397 was a unless, essentially 
unreadable duplicate of that message, hence removed.

I think this is a bit exagerated. The performance issues will only
appear if you have huge dicts and sets.
The issue Raymond raised is the potential impossibility of making the
change /after/ we settle on a stable ABI. The question is whether the
ABI will be enforced starting from 3.2, or from a later date.

[issue10058] Unclear PyString_AsStringAndSize return value

[Georg Brandl]

Georg Brandl  added the comment:

Same here.  There is only ever one return value on error unless documented 
otherwise, since the type of error is already contained in the exception that 
is set on return.
