I have multiple greenlets sending on a common socket. Is it guaranteed that each package sent via socket.sendall
is well separated or do I have to acquire a lock before each call to sendall
.
So I want to prevent the following scenario:
- g1 sends
ABCD
- g2 sends
1234
- received data is mixed up, for example
AB1234CD
- expected is either
ABCD1234
or1234ABCD
Update
After a look at the sourcecode I think this scenario cannot happen. But I have to use a lock because g1 or g2 can crash on the sendall
. Can someone confirm this?
