On Android and potencially other mobile platforms, WiFi drivers are configured
by default to discard any packet that is not directed to the unicast mac
address of the interface, this way they could save some battery but breaks
anything that is not unicast, such as broadcast discovery. To solve this
problem On such platforms provide methods to handle low level multicast
listening so we can receive advertisement from same broadcast domain nodes.
This method is called from other threads and apparently caused
a sporadic crash caought on Android.
See retroshare://forum?name=Got%20crash%20on%20Android%20with%20GDB%20backtrace&id=95de1451952d8c38cb1cdfdb85eed986&msgid=ac8c9d41f2cd0c9e8e290433c7f296fecb2d62b3
In Restbed one is not supposed to call session->yield outside the
threads controlled by Restbed. RetroShare JSON API async call were
calling session->yield from threads controlled by RetroShare all the
times, this caused crashes in some cases, like when the JSON API
socket timed out concurrently with the session->yield call .
To solve this problem session->yield from async
calls are now wrapped insto mService->schedule to ensure they are
executed on the right thread (aka one of the threads controlled by
Restbed).
While solving this issue I realized also that passing RsEvents as const
references around was quite limiting in cases where the event need to
be finally handled in another thread, in that case passing by const
reference the RsEvent needed to be copied by value into the thread
that process it, in this copy by value process the information of
which was the original specific type is lost, and then only the data
and methods from general RsEvents are available, unless the handler
does tricky stuff with type coercion etc. To solve this limitation
pass the events as std::shared_ptr<const RsEvent> seems the safer and
more elegant solution.
JSON API user would bet an unusable base64 blob due to RsTlv opaque JSON
serialization, this way the content of the set is serialized plainly
so it is usable through JSON API, without breaking binary
serialization compatibility.
We must stop using those RsTlv derived items.
Sending PGP fingerprint trough broadcast discovery is misleading in
terms of security, as those packets cannot be trusted for PGP
fingerprint verification, removing it reduce packet size and reduce the
risc of wrong usage of untrusted information
Rename from RsDisc to more descriptive RsGossipDiscovery
Keep full retrocompatibility suggesting usage of RsGossipDiscovery
Add capability to send and receive full RetroShare invitation
Emit event when receiving a full invitation
Start using new debug utilities
Use enum class instead of defines and constant where appropriate
This should bit by bit substitute RsNotify which would be very difficult
to support properly in JSON API.
The new system is much simpler to use also from the C++ side of the
moon.
BroadcastDiscovery take advantage of the new system to notify about new
non friend peer discovered, tested successfully also in JSON API.
Creating GXS groups imply a bunch of crypto operations that require lot
of time expecially on embedded device, channel creation was reported
as failed while it was still pending.
Reduce too long lines.
Print API error messages also on std::cerr.
