[issue2665] unable to launch IDLE on windows XP

[Leo]

New submission from Leo <[EMAIL PROTECTED]>:

I recently upgraded from python 2.3 to 2.5. But idle doesn't launch
anymore, either with right-clicking a .py program an doing "edit with
IDLE" or with launching the idle.py file itself. 
When I launch idle with the command line, it gives the following error
several times:

Warning : configHandler.py - IdleConf.GetThemeDict- 
problem retrieving theme element 'buitlin-foreground'
from theme 'vert theme'
returning default value: '#00'

Warning : configHandler.py - IdleConf.GetThemeDict- 
problem retrieving theme element 'buitlin-background'
from theme 'vert theme'
returning default value: '#ff'

[issue2665] unable to launch IDLE on windows XP

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc <[EMAIL PROTECTED]> added the comment:

I reproduced the problem.
- "python.exe idle.py"  works (with many warnings)
- "pythonw.exe idle.py" fails

pythonw.exe is a Windows (i.e. not a console) application, so sys.stderr
points to an invalid file descriptor; printing lot of warnings raises an
exception when the file tries to flush()...

As an immediate workaround, you may delete everything in the directory named
  c:/Documents and Settings/%USERNAME%/.idlerc
or if you feel it, add the missing entries in the file config-highlight.cfg.

I'll try to correct this problem for python2.5: replace 
   sys.stderr.write(warning) 
with
   try:
  sys.stderr.write(warning) 
   except IOError:
  pass

[issue2665] unable to launch IDLE on windows XP

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc <[EMAIL PROTECTED]> added the comment:

"buitlin"? Is is a typo while copying the error message?

The warnings are normal, these theme elements were added later. They
will disappear when you save the theme again.

Now, idle starts another process to interpret the commands, and use
sockets to communicate between them. You may have a firewall problem.

Can you try to run idle.py with the "-n" option? This does not create a
subprocess, all commands are run in the main process.

Leo <[EMAIL PROTECTED]> added the comment:

it's not "buitlin" but "builtin" of course.

idle launches when I use the command line, with or without "-n", but I'm
still unable to lauch it normally (by the right click or by the windows
menu ("Démarrer/Programmes/Python25/idle")).
Before, I used python 2.3 and it worked well. I uninstalled and
installed again python 2.5 several times but I still got the same
problem.. it isn't practical at all to lauch idle by the command line!
So I hope you'll have an idea to solve my problem...

ok, deleting the contents of .idlerc seems to work fine.

[issue2663] shutil.copytree glob-style filtering [patch]

[Alexander Belopolsky]

Alexander Belopolsky <[EMAIL PROTECTED]> added the comment:

On the interface, I would suggest renaming 'exclude' to 'ignore' for 
consistency with filecmp.dircmp. Also consider detecting file separator 
in the patterns and interpreting them as an absolute (if 
pattern.startswith(pathsep)) or relative with respect to src. 

On the implementation, consider making 'exclude_files' a set for a 
faster lookup.   It should also be possible to refactor the code to 
avoid checking the type of 'exclude' on every file and every recursion.

[issue2632] performance problem in socket._fileobject.read

[Gregory P. Smith]

Gregory P. Smith <[EMAIL PROTECTED]> added the comment:

Twisted fixed their problem for issue 1092502 by making recv()ed data
short lived by putting it into a StringIO for buffering.

I've attached a patch that does that for the socket module -and- gets
rid of any possibility of doing tiny size recvs in read() which is the
cause of the poor performance that this issue was filed about.

My patch also documents what _rbufsize is used for (readline) and makes
sane use of it with read.

When viewing the change, it is best to view it side by side next to the
old version rather than trying to comprehend it as a diff.

I believe this really fixes both issue 1092502 while at the same time
prevents introduction of a speed problem (this issue).

[issue2666] webbrowser.py doesn't properly handle BROWSER env var

[Oleg Broytmann]

New submission from Oleg Broytmann <[EMAIL PROTECTED]>:

webbrowser.py ignores browsers listed in the BROWSER environment
variables if it doesn't recognize the browser. For example, if I add
"links2" to the BROWSER env var, webbrowser.py ignores it.

It is because _synthesize() doesn't know how to handle an unknown
browser. The attached patch checks if _synthesize() doesn't register a
browser and registers a GenericBrowser.

Another approach would be to register GenericBrowser in _synthesize().

[issue2632] performance problem in socket._fileobject.read

[Ralf Schmitt]

Ralf Schmitt <[EMAIL PROTECTED]> added the comment:

(I think the twisted issue your talking about is:
http://twistedmatrix.com/trac/ticket/1079)

Your patch still contains this code:

 recv_size = min(rbufsize, left)
 data = self._sock.recv(recv_size)

This is IMHO wrong.  See my comments above.
