New submission from Jack Miller <[email protected]>:
I've discovered that using either 2.7.2 or 3.2.2 (from Arch) reorganizing gdbm
databases leave hanging file descriptors that will cause EAGAIN errors trying
to reopen it until the process is killed. For example:
Python 2.7.2 (default, Jan 31 2012, 13:19:49)
[GCC 4.6.2 20120120 (prerelease)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import gdbm
>>> o = gdbm.open("test27", "c")
>>> o.reorganize()
>>> o.close()
>>> o = gdbm.open("test27", "w")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
gdbm.error: (11, 'Resource temporarily unavailable')
>>>
By using lsof you can see that after reorganize() test27 has two open file
descriptors, and after close() one is still open with no (obvious) way to close
it. This happens with freshly created and populated databases and regardless of
open mode flags.
I also tested this on 3.2.2 with dbm.gnu and got identical behavior.
