When messages can't be sent to peer, we try to establish a send
connection - this causes messages to stack up as more and more unsent
messages are blocked on the dial lock.
* remove dial lock
* run reconnection loop in background task
* channel close race and deadlock fixes
* remove send lock, write chunks in one go
* push some of half-closed implementation to BufferStream
* fix some hangs where LPChannel readers and writers would not always
wake up
* simplify lazy channels
* fix close happening more than once in some orderings
* reenable connection tracking tests
* close channels first on mplex close such that consumers can read bytes
A notable difference is that BufferedStream is no longer considered EOF
until someone has actually read the EOF marker.
* docs, simplification
* add peer lifecycle events
* rework peer events to not use connection events
* don't use result in pubsub and switch init
* wip
* use ordered hashes and remove logscope
* logging
* add missing test
* small fixes
* mcache fixes
* remove timed cache - the window shifting already removes old messages
* ref -> object
* avoid unnecessary allocations with `[]` operator
* simplify init
* fix several gossipsub/floodsub issues
* floodsub, gossipsub: don't rebroadcast messages that fail validation
(!)
* floodsub, gossipsub: don't crash when unsubscribing from unknown
topics (!)
* gossipsub: don't send message to peers that are not interested in the
topic, when messages don't share topic list
* floodsub: don't repeat all messages for each message when
rebroadcasting
* floodsub: allow sending empty data
* floodsub: fix inefficient unsubscribe
* sync floodsub/gossipsub logging
* gossipsub: include incoming messages in mcache (!)
* gossipsub: don't rebroadcast already-seen messages (!)
* pubsubpeer: remove incoming/outgoing seen caches - these are already
handled in gossipsub, floodsub and will cause trouble when peers try to
resubscribe / regraft topics (because control messages will have same
digest)
* timedcache: reimplement without timers (fixes timer leaks and extreme
inefficiency due to per-message closures, futures etc)
* timedcache: ref -> obj
* remove send lock
When mplex receives data it will block until a reader has processed the
data. Thus, when a large message is received, such as a gossipsub
subscription table, all of mplex will be blocked until all reading is
finished.
However, if at the same time a `dial` to establish a gossipsub send
connection is ongoing, that `dial` will be blocked because mplex is no
longer reading data - specifically, it might indeed be the connection
that's processing the previous data that is waiting for a send
connection.
There are other problems with the current code:
* If an exception is raised, it is not necessarily raised for the same
connection as `p.sendConn`, so resetting `p.sendConn` in the exception
handling is wrong
* `p.isConnected` is checked before taking the lock - thus, if it
returns false, a new dial will be started. If a new task enters `send`
before dial is finished, it will also determine `p.isConnected` is
false, then get stuck on the lock - when the previous task finishes and
releases the lock, the new task will _also_ dial and thus reset
`p.sendConn` causing a leak.
* prefer existing connection
simplifies flow
* move pubsub of off switch, pass switch into pubsub
* use join on lpstreams
* properly cleanup up failed peers
* fix tests
* fix peertable hasPeerId
* fix tests
* rework sending, remove helpers from pubsubpeer, unify in broadcast
* further split broadcast into send
* use send where appropriate
* use formatIt
* improve trace

* revert change, bacause it causes races
* use stream directly in chronosstream
for now, chronos.AsyncStream is not used to provide any features on top
of chronos.Stream, so in order to simplify the code, chronosstream can
be used directly.
In particular, the exception handling is broken in the current
chronosstream - opening and closing the stream is simplified this way as
well.
A future implementation that actually takes advantage of the AsyncStream
features would wrap AsyncStream instead as a separate lpstream
implementation, leaving this one as-is.
