Comment(by atagar):
Ah ha! After a week of banging my head on the wall I got it...
{{{
atagar@morrigan:~/Desktop/stem$ python example.py
279042 descriptors in tarball.
279042 descriptors in extracted directory.
}}}
The difference is that I dropped a single descriptor:
server-descriptors-2012-12/5/6/564778a0a0aea0d6c6c0ee4bbce9c9233a0d70cd
Something is seriously screwy about its contact line. In vim it appears
as...
^TÃ^Xcontact root@[ipaddress]
... but while parsing it causes an exception because it can't be converted
to ASCII. When I tried (... repeatedly) to log output the logging
exception with those characters corrupted the output (causing the log file
to be truncated to 6k of binary, and peg my cpu when viewed in vim or
less).
So... er, yea. Fun. The descriptor file is malformed (since the characters
appear before the contact keyword) but stem certainly shouldn't choke this
way on... whatever that is. I'll add this descriptor to our integ tests
and make it fail more gracefully.
