Goal: "remote" tracebacks have file/lineno references to local source code
Current Problem:
tracebacks have file/lineno references that point to one
large file (consisting of all source code of all modules that
we sent as a bootstrap). Makes debugging execnet harder.
solution variant 0: minimal change to source code
at master side: send name/source pairs
at slave side: put each module into own file, re-using basename of source file
solution variant 1: aimed at simplicity
pack and send zip of py lib containing py.__.execnet, py.__.thread, etc
put this into some file-location at the other side, add it to sys.path
(or experiment with zipfile-imports over RAM and sys.meta_hooks/path_hooks)
solution variant 2: aimed at minimizing bandwidth usage
initiating side receiving side
-------------------------------------------------------------
loop:
send [dottedname1: hash1]
serve_hash_requests
if not lookup(hash1):
send(dottedname1: hash1)
content = receive(hash1)
else:
content = get(hash1)
