descriptor as instance attribute
by Jon Wells Jan. 9, 2012

Jan. 9, 2012

I can't find an answer to this grovelling through get user info. on descriptors. Assuming desc() is a data descriptor class why are the following not the same??? class poop(object): var = desc() and class poop(object): def __init__(self): self.var = desc() In the second form the descriptor protocol for access to 'var' is ignored. Would seem to not make sense to me. jon.

Can rewinddir() end up touching the filesystem to retrieve data? I noticed that your previous change (the one this checkin reverted) moved it outside the GIL release macros.

A question about the subprocess implementation
by Vinay Sajip Jan. 8, 2012

Jan. 8, 2012

The subprocess.Popen constructor takes stdin, stdout and stderr keyword arguments which are supposed to represent the file handles of the child process. The object also has stdin, stdout and stderr attributes, which one would naively expect to correspond to the passed in values, except where you pass in e.g. subprocess.PIPE (in which case the corresponding attribute would be set to an actual stream or descriptor). However, in common cases, even when keyword arguments are passed in, the … [View More]
