Just to clarify: my patch does not remove SSL at all. SSL is there and
works as before. The only difference is that it's not trampolined into
eventlet anymore. The root cause is the conflict between eventlet's
green threads, which require faking of blocking sockets, and SSL, which
requires looping
Although I don't think that SSL should be completely removed from swift,
I do agree with Andrew that it should never be used in production on the
proxy server. Python's SSL handling also causes the ssl sockets to block
and severely limits concurrent connections.
SSL support in the proxy is useful
FYI
from the source for eventlet/green/ssl.py:
Python nonblocking ssl objects don't give errors when the other
endof the socket is closed (they do notice when the other end is
shutdown,though). Any write/read operations will simply hang if
the socket isclosed from the other end.
Pete, yes, with plain httplib swift manages to upload the file without
significant CPU usage, in my test it is around 7-10% which is still high
compared to the curl version (around 1%) but I guess one can't get
better performance from httplib.
