New submission from Buck Golemon :
In our environment, we have a wrapper which enables optimization by default
(-OO). Most commandline tools which have a mode-changing flag such as this,
also have a flag to do the opposite ( see: ls -t -U, wget -nv -v, ).
I'd like to implement one or bo
Buck Golemon added the comment:
Minimal demo:
$ setenv PYTHONOPTIMIZE 0
$ python3.1 -OO -c "print(__debug__)"
False
I've used this code to get the desired functionality:
if [[ $TESTING == 1 || ${PYTHONOPTIMIZE-2} =~ '^(0*|)$' ]]; then
#someone is requesting no o
Buck Golemon added the comment:
If I understand this code, it means that PYTHONOPTIMIZE set to 1 or 2 works as
expected, but set to 0, gives a flag value of 1.

add_flag(int flag, const char *envs)
{
int env = atoi(envs);
if (flag < env)
flag =
Buck Golemon added the comment:
"that number of times" isn't exactly accurate either, since "0" is effectively
interpreted as "1".
This change would only adversely affect people who use no -O option, set
PYTHONOPTIMIZE to '0', and need optimizat

The file is here:

The second if statement is doing exactly what I find troubling: set the flag
even if the incoming value is 0.
I guess this is to handle the empty string case, such as

On Ubuntu 10.10 (maverick), python2.6 is functioning correctly, but python2.7

sem_open works fine (python2.6 is using it), but the python2.7 build process
didn't detect it properly. This is either a bug with Ubuntu's python2.7 bui

How do I know the configuration options that the Ubuntu packager used?

python2.7.1+ from mercurial supports sem_open (and multiprocessing) just fine.
doko: Could you help us figure out why the ubuntu 10.10 python2.7 build has
this issue? I believe this issue should be assigned to you?
Relevant lines from the config.log
Buck Golemon added the comment:
@Barry: Yes, it's still a problem.
The ubuntu 10.10 python2.7 still has no multiprocessing.
Since the EOL is April 2012, it needs fixed.
It may be considered an invalid python bug, since it seems to be strictly
related to Ubuntu packaging, but I though

1) As long as x is valid, I expect that urlunsplit(urlsplit(x)) == x
2) yelp:///foo is a well-formed (albeit odd) url. It it similar to file:///tmp:
it specifies the /foo resource, on the "current" host, using the yelp protocol

Buck Golemon added the comment:
Well i think the real issue is that you can't enumerate the protocals that "use
netloc". All protocols are allowed to have a netloc. the smb: protocol
certainly does, but it's not in the list.
The core issue is that smb:/foo and smb:///fo

Let's examine x://

So this is okay if authority and path-abempty can both be empty strings.
authority = [ userinfo "@

I'm not sure what your problem is, but comp.lang.python might be a
better place to ask. It's not clear that this is a bug yet.

If there's no difference then they should work the same?
I agree there's probably little value in 'fixing' it.
