- instead of being processed in the ReceiveQueue thread, uploads are now done
in a dedicated thread. Only the parsing is done in ReceiveQueue thread.
- the UploadThread is modelled based on the DownloadThred, but simpler.
- it checks for intersection attack, eliminates duplicates and restricts the
write buffer size to 2MB (may still grow slightly higher if too many big
objects are requested, but the absolute limit appears to be about 4.5MB in the
worst case scenario).
- the restriction of the write buffer may cause some upload throttling (to
about 2MB per second per connection), but can be optimised later
- fixes#1414
- 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
- change forking exit order as systemd expects (wait until child is
ready, then exit parent, then grandparent)
- fix signal handler if prctl not installed
- revert recent PID file changes
- 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)
- now tracks downloads globally too, so it doesn't request the same
object from multiple peers at the same time
- retries at the earliest every minute
- stops trying to download an object after an hour
- minor fixes in retrying downloading invalid objects
- this thread is for spreading new/updated addresses in active
connections, analogous to the InvThread
- it doesn't do anything yet, this is just a dummy queue at the moment
- should prevent the same object being re-requested indefinitely
- locking for object tracking
- move SSL-specific error handling to TLSDispatcher
- observe maximum connection limit when accepting a new connection
- stack depth test (for debugging purposes)
- separate download thread
- connection pool init moved to main thread
- better handling of WSA* checks on non-windows systems
- handle EBADF on Windows/select
- better timeouts / loop lengths in main asyncore loop and
spawning new connections
- remove InvThread prints
- asyncore is now on by default
- inv announcements implemented
- bandwidth limit implemented / fixed
- stats on download / upload speed now work
- make prints into logger
- limit knownNodes to 20k as it was before
- green light fixed
- other minor fixes
- bugfixes
- UDP socket for local peer discovery
- new function assembleAddr to unify creating address command
- open port checker functionality (inactive)
- sendBigInv is done in a thread separate from the network IO
thread
- separate queue for processing blocking stuff on reception
- rewrote write buffer as a queue
- some addr handling
- number of half open connections correct
- most of the stuff is done so it partially works
- disabled pollers other than select (debugging necessary)
- can switch in the settings, section network, option asyncore (defaults
to False)
- networkDefaultProofOfWorkNonceTrialsPerByte and
networkDefaultPayloadLengthExtraBytes cyclic import fix
- PyBitmessage should launch now when there's no keys.dat
- rearranged code to reduce cyclic dependencies
- doCleanShutdown is separated in shutdown.py
- shared queues are separated in queues.py
- some default values were moved to defaults.py
- knownnodes partially moved to knownnodes.py
- version command sends list of all participating streams
- biginv sends lists of hosts for all streams the peer wants (plus
immediate children)
- objects will spread to all peers that advertise the associated stream
- please note these are just network subsystem adjustments, streams
aren't actually usable yet
- fixes errors introduced in the earlier refactoring
- more variables moved to state.py
- path finding functions moved to paths.py
- remembers IPv6 network unreachable (in the future can be used to skip
IPv6 for a while)
- got rid of shared config parser and made it into a singleton
- refactored safeConfigGetBoolean as a method of the config singleton
- refactored safeConfigGet as a method of the config singleton
- moved softwareVersion from shared.py into version.py
- moved some global variables from shared.py into state.py
- moved some protocol-specific functions from shared.py into protocol.py
- minor refactoring, made it into singleton instead of a shared global
variable. This makes it a little bit cleaner and moves the class into
a separate file
- removed duplicate inventory locking
- renamed singleton.py to singleinstance.py (this is the code that
ensures only one instance of PyBitmessage runs at the same time)
- you can now use SMTP to send messages
- uses bmaddr.lan domain
- runs on 127.0.0.8425 if you set "smtpd" to True
- mandatory authentication with smtpdusername and smtpdpassword
- handles old dialog versions better if using curses
- can spawn SMTP delivery thread if configured (only when in daemon
mode)
- daemonized mode now works more like it's properly supposed to on unix
(double fork etc). You may have to adjust your init scripts, when
when using upstart for example you should now use "expect daemon"
- daemon mode now cleanly shuts down when TERM/INT signal is received
We already do this for the SIGINT kill signal. The change allows us to do a clean
shutdown of PyBitmessage when its process has been separated from the terminal.
