diff Python/ceval.c @ 1293:ac3c80abbf43 legacy-trunk

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
* classobject.c: in instance_getattr, don't make a method out of a function found as instance data. * socketmodule.c: added 'flags' argument sendto/recvfrom, rewrite argument parsing in send/recv. * More changes related to access (terminology change: owner instead of class; allow any object as owner; local/global variables are owned by their dictionary, only class/instance data is owned by the class; "from...import *" now only imports objects with public access; etc.)
