[issue16233] IDLE: conceptual problems with *Class browser*

[Roger Serwy]

Roger Serwy added the comment:

Saving the shell to a file allows the class browser to function. However a 
class browser for a syntax-incorrect file due to prompts and stdout contents 
can also pose a conceptual problem.

I suggest that the error message be modified to include a corrective action: 
"This buffer has no associated filename. Please save this buffer to a file and 
try again."

[issue16286] Optimize a==b and a!=b for bytes and str

[Raymond Hettinger]

Raymond Hettinger added the comment:

Rather than see statistics, I'm curious about what circumstances where the 
optimization would kick in.   Interned strings are pre-hashed but they already 
benefit from an identity-implies-equality check.  Dicts and sets already 
incorporate a check-hash-before-equality check.

That raises the question of what strings ever have had their hash already 
computed if the string hasn't been interned or has been used in a dict or set?

P.S.  I rather like the optimization and don't want to discourage it.  I'm just 
curious about what the current optimizations are missing.

[issue15853] IDLE crashes selecting Preferences menu with OS X ActiveState Tcl/Tk 8.5.12.1

[Ned Deily]

Ned Deily added the comment:

Thanks for everyone's help on this.  To summarize, opening IDLE's Preferences 
menu when Python is dynamically linking to ActiveTcl 8.5.12.1 (at this writing, 
the most recent version) causes Tk to crash.  The committed patches here avoid 
the crash by changing Tk calls from IDLE.  These fixes will be released in the 
next set of maintenance releases: 2.7.4, 3.2.4, 3.3.1, and in 3.4.0.  Until 
they are installed, another workaround is to revert to an earlier version of 
ActiveTcl; 8.5.11.1 is recommended:

http://downloads.activestate.com/ActiveTcl/releases/8.5.11.1/

As always, http://www.python.org/download/mac/tcltk/ will be updated with 
current recommendations.

Doesn't Solaris have poll()?  If so then I don't see why one would want to use 
/dev/poll in the single fd case.

[Richard Oudkerk]

Richard Oudkerk added the comment:

>

With a single fd poll is a bit faster than select:

$ python -m timeit -s 'from select import select' 'select([0],[],[],0)'
10 loops, best of 3: 2.99 usec per loop

$ python -m timeit -s 'from select import poll, POLLIN' 
'p=poll();p.register(0,POLLIN);p.poll(0)'
10 loops, best of 3: 2.8 usec per loop

The single fd case is the most important one -- see below.

It was introduced in Python 3.3 and is only really there to allow cross 
platform Windows/Unix multiplexing.  It is (now) also used internally by 
Connection.poll() and Queue.get() with a single fd.

In retrospect it would probably have been better to have implemented poll style 
multiplexing on Windows.

[issue5803] email/quoprimime: encode and decode are very slow on large messages

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

3.2+ already use StringIO, there is no nonlinearity. On 2.7 I couldn't find the 
nonlinearity with the texts of up to 100 MB.

Therefore the path outdated as bugfix.

However it shows 20-30x speedup on 2.7. It would be worth port it to 3.4. This 
will be a significant enhancement (if the patch can preserve the current 
semantics).

That sounds like premature optimization. If you are concerned about that
you could add some caching of the poll object.

Well, can't you just create a mapping of the fds to the objects?

Your patch already has that problem by the way, and it's even worse
since it will trigger in random conditions (when some fd is > 512).

I guess the patch could do

if any(x[1] & POLLNVAL for x in ret):
raise ValueError('invalid file descriptor')

Also, I don't think there is any need to unregister the fds since you are just 
removing entries from an internal dict which will be garbage collected.

I don't know if patching 2.7, 3.2, 3.3 to use/fallback on poll() would be 
allowed as a bug fix.  When, if ever, will the next 2.7 release happen?

select() can deal with both while poll() does not (it will return a list of

I'm not sure how "public" multiprocessing.connection.wait() is considered and

[issue12238] Readline module loading in interactive mode

[Antoine Pitrou]

Antoine Pitrou added the comment:

Regardless, I'm not sure what we should do about this issue. Loading readline 
is obviously provided as a convenience to make the interpreter prompt easier to 
use. Several of us would probably like to go a bit further and also add 
tab-completion (see issue5845).

It stands that while the -S and -E option allow to disable any customization a 
user might have done (which is necessary for e.g. suid scripts), the automatic 
insertion of '' into sys.path has no way of being undone.

Antoine Pitrou added the comment:

Serhiy, I don't think it's fixed in 3.3, or perhaps I'm misunderstanding what 
you mean by "fixed". If you create readline.cpython-33m.so in your cwd and then 
run python, the fake readline will still be loaded instead of the real one.

For example (here with 3.4):

$ touch readline.cpython-34dm.so
$ ./python
Python 3.4.0a0 (default:2a0c9472c89c, Oct 21 2012, 23:24:06)

[issue16136] Removal of VMS support

[Sandeep Mathew]

Sandeep Mathew added the comment:

Hi ,

I love VMS very much, I could not concentrate actively on python
because other work commitments ate up most of my time. I have
left my job at HP and am now a PhD student and university of Nevada ,
Reno .  Now that I do not have any professional commitments , I should
be able to work on it in a more timely manner. I had used python for
an internal project in HP.


The problem now I have is that I need access to a VMS  machine. I was
not able to setup a build bot because buildbot needed some ports to be
open , the machine provided HP did not give privilleges to do that.
Another thing was that they wanted me to use gnv to compile python in
VMS . I however did not really agree with it , gnv is buggy and you
need to enable millions to of hacks to gets programs to compile.
Programs written for VMS should be written the VMS way not the unix
way. I was able to get Python 3.x to compile using gnv finally but it would not 
run properly. Is it possible for anyone to provide a VMS box with C Compiler 
and tools ( MMS) so that I can start working on it again. I will try asking HP 
, whether they would allow me to start working on it on the old VMS cluster 
they provided.

No directly, no:  I'd hit a similar problem in some of our own code, leading to 
a signature change from "def do_later(fn, *args, **kwargs)" to "def 
do_later(fn, arg, kwargs)".  Then it occurred to me to wonder how 
Executor.submit handled the issue.

The workaround seems fine;  feel free to close as "won't fix".

gets hit) and falls back on using poll().

This is the failure I get when running tests on Linux.
It is related to issue 3321 and I'm not sure what to do with it (remove the 
test maybe?).

[issue16301] localhost() and thishost() in urllib/request.py

[Senthil Kumaran]

New submission from Senthil Kumaran:

localhost() returns a string and thishost() returns tuple. In 
urllib/request.py, for file:// protocol, there is a verification to check to if 
the host is in the localhost and check happens:

socket.gethostbyname(host) in (localhost() + thishost())):

This is clearly wrong for the above mentioned reason. It should be changed to 
this, wrapping localhost with tuple() or making localhost return a tuple, which 
will be consistent with thishost

socket.gethostbyname(host) in (tuple(localhost()) + thishost())):

[anatoly techtonik]

anatoly techtonik added the comment:

RDM> 'build' is pretty much universally understood to be something that can be 
blown away

That's not true anymore in 2012. Why follow the bad practice?

I also want to know what open source software project are you referring to. 
From my experience 'build' directory name is an ancient legacy from Unix C 
compilers of previous century. Java doesn't use it, MSVC never did it, CMake 
doesn't have it, Go seems to build everything in temp dir.

[issue16297] make csv.DictReader.__init__ use self.fieldnames

[R. David Murray]

R. David Murray added the comment:

I think it is not an invalid request.  However, what is the use case?  Normally 
a class will manipulate the "real" variable, and the getter/setter is the 
public API.  Without a good use case it doesn't seem worth changing that bit of 
the init method.

I see no reason to make this change.  'build' is pretty much universally

>From the Buildbot failure -

I remember that we restricted the access for file:// scheme to localhost only 
for Windows/Cygwin. In terms of exception raised it could either be consistent 
with other platforms and raise URLError or it could be for good reasons, the 
tests may need to be tweaked for windows.

[anatoly techtonik]

New submission from anatoly techtonik:

Currently distutils builds files in a temporary directory named 'build' in 
current dir if not specified otherwise. It will be pythonic to name this 
directory to be __build__ be default to distinguish it from project specific 
directories and clarify that this one can be safely removed (much like 
__pycache__).

[issue13376] readline: pre_input_hook not getting called

[Ronald Oussoren]

Ronald Oussoren added the comment:

1) Issue is still present with libedit on OSX 10.8

2) Libedit on OSX doesn't call rl_pre_input_hook when using the '#if 
defined(HAVE_RL_CALLBACK) && defined(HAVE_SELECT)' branch in the readline 
extension (that is, not calling readline(3), but using rl_callback_read_char).

3) When I patch pyconfig.h to enable the code patch that does use readline the 
callback gets called, but that doesn't affect the readline buffer.

Manually ensuring that the pre_input_hook is called at the right time is easy 
enough, but I don't have time to research why readline.insert_text (and/or 
readline.redisplay) doesn't work. The source code at 
 
looks fine.

As I see in pywin32 sources status.adapter_address is bytes in Python 3.

Here is a trivial patch.

[issue16298] httplib.HTTPResponse.read could potentially leave the socket opened forever

[Eran Rundstein]

New submission from Eran Rundstein:

When calling HTTPResponse.read() on a response that is:
a. not chunked
b. contains no content-length header
the underlying socket (referenced by self.fp) will never get closed (through 
self.close())

The offending code is at the bottom of the read() function:
s = self.fp.read(amt)
if self.length is not None:
self.length -= len(s)
if not self.length:
self.close()
return s
As seen, if self.length is None, even when the server closes the connection 
(causing self.fp.read to return ''), the socket will not get closed.

btw, this may be the cause of Issue15633 (http://bugs.python.org/issue15633)

[issue16291] Enable darwin-host cross compilation. Tested with build=linux, host=darwin

[Ray Donnelly]

Ray Donnelly added the comment:

> A small question about the patch, why this case in the cross_arch function:

>From a real Mac Book Pro:

$ uname -a
Darwin MACBOOKPRO.local 11.4.2 Darwin Kernel Version 11.4.2: Thu Aug 23 
16:25:48 PDT 2012; root:xnu-1699.32.7~1/RELEASE_X86_64 x86_64
$ /usr/bin/arch
i386
$ uname -m
x86_64

It would seem arch on OS X can only be used to determine PPC vs Intel (which is 
all that configure uses it for anyway).

> Why is cross-compiling to OSX useful at all?

Cross compiling is always useful for build engineers who have to target 
multiple hosts. 

> You still have to test if the output of the compilation works, and for that 
> you need an OSX system.

Ideally yes, or a Virtual Machine with OSX on it or confidence based on the 
results of a previous test built with the same sources or maloader (...though 
maybe not, I've never personally tried maloader).

> The patch will only help with cross-compiling C code, it won't compile 
> resource files (like the NIB file in Python Launcher)

My personal interest is for having Python embedded in other things (GDB) and 
using it from the command-line. Python Launcher is not part of the scope.

> This will make support harder, I already get support questions where the 
> answer depends on the way Python was build and that will likely get worse

I'd be happy to do whatever I can to help out with this. If we could identify 
in the build that it was built via cross compilation somehow or have my email 
address in the help would that make it more palatable?

The users would get the SDK from being registered as a developer with Apple. As 
for the license, while also not being a lawyer, my interpretation is this:

In the Xcode License.rtf file (and the Command Line tools license), the 
relevant part is "you are granted a limited, non-exclusive license to use the 
Developer Software on Apple-branded computers to develop and test application 
and other software". This doesn't say anything about the OS that's running on 
said Apple-branded computer, and my interpretation is that you could install a 
Linux distro on an Apple computer or on a VM on an Apple computer and still be 
compliant with that license.

[issue14892] 'import readline' hangs when launching with '&' on BSD and OS X

[Ronald Oussoren]

Ronald Oussoren added the comment:

I've just tested this on OSX 10.8.2 and the problem is not present there (that 
is, 'python -c "import deadline" &' does not hang)

The problem is present on OSX 10.6.8, and when using ksh(1) you can see why the 
process is stopped:

[1] + Stopped(SIGTTOU) python -c 'import readline' &

That signal is generated when the program generates output to a tty and the 
TOSTOP option of stty is active.  Whether or not that option is active is OS 
configuration (and can be changed using the stty command).

Reading the option:

import termios
lflags = termios.tcgetattr(0)[3]
print (lflags & termios.TOSTOP) != 0

Oddly enough the option off on both OSX 10.6 and 10.8, which point to a bug in 
OSX 10.6 (or to a misunderstanding of low-level tty programming details on my 
part which would not be unlikely)

Anyway, there is an easy workaround: before importing readline add:

import signal
signal.signal(signal.SIGTTOU, signal.SIG_IGN)

This ignores the SIGTTOU option and allows me to import readline on the 
background.

IMHO This issue can be closed because this behavior is not a Python bug but a 
platform feature.
