[issue1684] CGIHTTPServer does not chdir prior to executing the CGI script

[Christian Heimes]

Christian Heimes added the comment:

A small note from me:

Your proposed patch is no good and is going to lead to strange, hard to
debug bugs in your app. os.chdir() isn't safe in a threaded environment.
You must protect the entire section with a global lock.

[issue1684] CGIHTTPServer does not chdir prior to executing the CGI script

[Fazal Majid]

Fazal Majid added the comment:

MT-safety has nothing to do with this. The os.chdir() is invoked from
the new child process that is forked just prior to calling execve() to
run the CGI script, after which it exits. The parent CGIHTTPServer may
be multithreaded, but invoking the CGI script is not a concurrent affair.

[issue1691] feature request: methods that modify instances should return instance

[Peter Farson]

New submission from Peter Farson:

Here's an example:
I'd like to be able to reverse a list for iterating...
for i in range(10).reverse()

This could work if reverse method returned self, but currently it
doesn't return anything.  I think the overhead is slight and worth it.

[issue1691] feature request: methods that modify instances should return instance

[Christian Heimes]

Christian Heimes added the comment:

No, it's too confusing for users and it might hide bugs. The core types
either change an object in place and return None *OR* the method returns
a  modified object. It's a design decision we won't change.

In your case you can use the reversed(range(10)) wrapper. Python has
several wrappers like reversed() and sorted().

[issue1677] Ctrl-C will exit out of Python interpreter in Windows

[Isaul Vargas]

Isaul Vargas added the comment:

I wanted to add that this issue also affects python 2.5.1 on the Mac.
Sometimes I may be writing something in the interpreter and I decide to 
invalidate my input by pressing Ctrl-C. This will exit the interpreter 
occasionally. I think it would be a good idea to see if there's a way 
to make the interpreter bullet proof from Ctrl-C, or at least good 
enough so that a single Ctrl-c won't cause the interpreter to exit.

[issue1692] Syntax Error exception dosen't print string; not informative

[Isaul Vargas]

New submission from Isaul Vargas:

Python 3.0 doesn't print the string with the carat underneath when 
there is a syntax error.

>>> if x
SyntaxError: invalid syntax (, line1)
>>> if (x=5):
SyntaxError: invalid syntax (, line 1)

Python 2.x behavior:

>>> if (x=5): pass
  File "", line 1
if (x=5): pass

>>> if x
  File "", line 1
if x

[issue1760357] ZipFile.write fails with bad modification time

[Alan McIntyre]

Alan McIntyre added the comment:

At the moment I don't have a Windows machine available, but on my Mac,
time.localtime doesn't seem to mind interpreting negative input values.
 So I doubt that forcing timestamps to be non-negative is the way to fix
this. 

I poked around a bit in the current 2.6 source, and it seems to me that
in this case the Windows XP localtime function doesn't like a timestamp
value that was generated by the same platform's stat function.  It seems
like raising a ValueError is the correct thing for the time module to
do, since it relies on the platform to do the conversions; what should
zipfile.writestr do?  I don't like the idea of silently using some dummy
timestamp if the conversion of os.stat results fails, and I can't think
of an alternative at the moment.

[issue1650] IDLE: help() displays output on the wrong shell

[Kurt B. Kaiser]

Kurt B. Kaiser added the comment:

Yes, and it does on linux, also.  Someone changed the way help() 
works.  Since the help listing is often extensive and clutters up the 
shell, I'm thinking that the best solution would be to pop up a new 
window.  I haven't got around to addressing either the bug or a new 
design.

[issue1647] IDLE messes around with sys.exitfunc

[Kurt B. Kaiser]

Kurt B. Kaiser added the comment:

It was done for VPython support, as described in the docstring in 
run.py:exit().  What are you doing, removing sys.exitfunc from 
2.6? 

The 3.0 run.py code was changed to use atexit._clear().
