[New-bugs-announce] [issue12996] multiprocessing.Connection endianness issue

[Charles-François Natali]

New submission from Charles-François Natali <neologix at free.fr>:

Since the rewrite in pure Python of multiprocessing.Connection (issue #11743), multiprocessing.Connection sends and receives the length of the data (used as header) in host byte order.
This will break if the connection's endpoints are on machine with different endianness.
Patch attached (it also removes an unnecessary computation of the length of the data being sent).
