shutil.rmtree raises "OSError: [Errno 39] Directory not empty" exception
Hello, Has anybody seen an exception "OSError: [Errno 39] Directory not empty" raised by shutil.rmtree? The code that raised an exception creates a lot of directories with files, and then removes them. I got an exception when one of such directories was removed. Here is the backtrace: shutil.rmtree(filename) File "/usr/lib64/python2.5/shutil.py", line 178, in rmtree onerror(os.rmdir, path, sys.exc_info()) File "/usr/lib64/python2.5/shutil.py", line 176, in rmtree os.rmdir(path) OSError: [Errno 39] Directory not empty: /path/to/my/dir According to the documentation, shutil.rmtree should not care about directory being not empty. Thanks for the help, Masha liu...@usc.edu -- http://mail.python.org/mailman/listinfo/python-list
Re: shutil.rmtree raises "OSError: [Errno 39] Directory not empty" exception
Thanks for pointing out the parameters for ignore_errors and an onerror callback function. I have been running this code for more than an year, and this is the very first time I see the problem. We switched to the NFS mounted storage though, but there is nothing unusual logged by the system in the /var/log/messages. I checked the permissions - the directory is still there and has exactly the same permissions as other successfully copied and removed directories (the very same process creates the directory and later removes it). The directory is empty though - so the process removed all the entries in it, then some kind of an error occured that triggered the exception. There are lots of similar directories that the process creates and removes, but only one of them raised an exception.

This sounds suspiciously like a permission issue. rmtree() *should* walk the tree removing items *if it can*. If a file can't be deleted, it treats it as an error. rmtree() takes parameters for ignore_errors and an onerror callback function, so you can catch these error conditions. -tkc -- http://mail.python.org/mailman/listinfo/python-list
Any built-in function for smallest positive floating point number?
Hello everybody, Is somebody aware of built-in Python's function that would return a value for smallest positive double precision floating point number (analogous to 'realmin' in Matlab). Python has built-in sys.maxint but I could not find anything for float. Any help would be greatly appreciated. Thanks, Masha liu...@usc.edu -- http://mail.python.org/mailman/listinfo/python-list

A bit more of googling gave me an answer: >>> import numpy as np >>> np.finfo(np.double).tiny array(2.2250738585072014e-308) >>> Thanks, Masha liu...@usc.edu On Aug 11, 2009, at 10:29 AM, Maria Liukis wrote: Hello everybody, Is somebody aware of built-in Python's function that would return a value for smallest positive double precision floating point number (analogous to 'realmin' in Matlab).
