Logic borrowed from bitcoin, see CNetAddr::GetGroup() in src/netaddress.cpp
Simplified, so may not work fully identically but for our purposes it's good
enough. Won't connect to more than one host from a /16 subnet on IPv4 and a /32
subnet on IPv6.
and use logging without risk of circular import. Only subpackage
that imports from debug is bitmessageqt - because it also uses
debug.resetLogging().
Instead of from debug import logger is now recommended to use:
import logging
logger = logging.getLogger('default')
All subclasses of StoppableThread now have a logger attribute.
All threading related stuff except for set_thread_name()
was moved from helper_threading to network.threads.
Fixed two my mistakes from previous edit of debug in a1a8d3a:
- logger.handlers is not dict but iterable
- sys.excepthook should be set unconditionally
- new options in network section: onionsocksproxytype,
onionsockshostname and onionsocksport. These allow to separate
connectivity types for onion and non-onion addresses, e.g. connect to
clear nodes over clearnet and onions over tor
- also remove some obsolete imports
- dandelion fixes
- try to wait as long as possible before expiration if there are no
outbound connections
- expire in invThread rather than singleCleaner thread
- deduplication of code in inv and dinv command methods
- turn on by default, seems to work correctly now
- turn off dandelion if outbound connections are disabled
- start tracking downloads earlier, and faster download loop
- remove some obsolete lines
- minor PEP8 updates
- I thought this is done automatically through garbage collection, but I
think as the channel is still assigned in the asyncore map, it needs
to be done manually. Basically filehandle limit exceeded and it
crashed
- dandelion would always think there is a cycle and trigger fluff
- cycle fluff trigger didn't correctly re-download and re-announce the
object. Now it remembers between (d)inv and object commands that it's
in a fluff trigger phase.
- fixes and feedback from @gfanti and @amiller
- addresses #1049
- minor refactoring
- two global child stems with fixed mapping between parent and
child stem
- allow child stems which don't support dandelion
- only allow outbound connections to be stems
- adjust stems if opening/closing outbound connections (should
allow partial dandelion functionality when not enough outbound
connections are available instead of breaking)
- more exception handling
- only use outbound connections for stems
(thanks to @amillter for info)
- don't create stems if config disabled
- addresses #1049
