- sometimes a node would send an "inv" about an object but then not
provide it when requested. This could be that it expired in the
meantime or it was an attack or a bug. This patch will forget that the
object exists if was requested too many times and not received.
- remember what was requested from which node
- remember if it was received
- re-request object if we haven't received any new object for more than
a minute
- rely on dict quasi-random order instead of an additional shuffle
- request an object once per minute
- stop check after count objects have been found
- tries to avoid calling senddata it it would block receiveDataThread,
allowing fore more asynchronous operation
- request objects in chunks of 100 (CPU performance optimisation)
- moved logic into a Missing singleton
- shouldn't try to download duplicates anymore, only requests a hash
once every 5 minutes and not from the same host
- removed obsoleted variables
- the "Objects to be synced" in the Network tab should now be correct
- removed some checks which aren't necessary anymore in my opinion
- fix missing self in Throttle (thanks landscape.io)
- send buffer to send multiple commands in one TCP packet
- recv/send operation size now based on bandwith limit
- send queue limited to 100 entries
- buffer getdata commands to fill send queue, instead of waiting for the
data packet to arrive first (i.e. allow getdata to work asynchronously)
- SSL handshake would often fail, because verack packet was being sent
at the same time as the do_handshake was executed in a different
thread. This makes it so that do_handshake waits until verack is done
sending.
- also minor modifications in SSLContext initialisation
- 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)
- TLS handshake in python is apparently always asynchronous, so it needs
proper handling of SSLWantReadError and SSLWantWriteError
- also adds a timeout and a proper shutdown if handshake fails
- Linux users often don't know that the C PoW is available and complain
it's slow. This will try to build it, and adds availability
notification in the status bar
- also, the updateStatusBar signal now allows emphasised notifications,
which will remain visible for a longer period of time and also
reappear if a status change happened in the meantime
- sometimes SSL connections unnecessarily disconnected on non-fatal
errors. This should fix that. This is however a short term solution
because of migrating to asyncore which has its own error handling
- when you have multiple OpenCL drivers at the same time, e.g. intel and
nvidia, they won't mix leading to crashes. This patch makes it
possible to select which driver to use by listing the available
vendors
- refactored to use the .ui file
- input logic change, address is always optional
- interactive input validation
- runs asynchronously to the main window
- address generator thread can now validate chans in addition to just
adding them
