      bitswap/provide: improved rate limiting · 06b49918
      Juan Batiz-Benet authored 
      this PR greatly speeds up providing and add.

(1) Instead of idling workers, we move to a ratelimiter-based worker.
We put this max at 512, so that means _up to_ 512 goroutines. This
is very small load on the node, as each worker is providing to the
dht, which means mostly waiting. It DOES put a large load on the DHT.
but i want to try this out for a while and see if it's a problem.
We can decide later if it is a problem for the network (nothing
stops anyone from re-compiling, but the defaults of course matter).

(2) We add a buffer size for provideKeys, which means that we block
the add process much less. this is a very cheap buffer, as it only
stores keys (it may be even cheaper with a lock + ring buffer
instead of a channel...). This makes add blazing fast-- it was being
rate limited by providing. Add should not be ratelimited by providing
(much, if any) as the user wants to just store the stuff in the local
node's repo. This buffer is initially set to 4096, which means:

  4096 * keysize (~258 bytes + go overhead) ~ 1-1.5MB

this buffer only last a few sec to mins, and is an ok thing to do
for the sake of very fast adds. (this could be a configurable
paramter, certainly for low-mem footprint use cases). At the moment
this is not much, compared to block sizes.

(3) We make the providing EventBegin() + Done(), so that we can
track how long a provide takes, and we can remove workers as they
finish in bsdash and similar tools.

      Move findproviders out of main block request path · e5aa2acc
      Jeromy authored 
      This PR moves the addition of new blocks to our wantlist (and their
subsequent broadcast to the network) outside of the clientWorker loop.
This allows blocks to more quickly propogate to peers we are already
connected to, where before we had to wait for the previous findProviders
call in clientworker to complete before we could notify our partners of
the next blocks that we want. I then changed the naming of the
clientWorker and related variables to be a bit more appropriate to the
model. Although the clientWorker (now named providerConnector) feels a
bit awkward and should probably be changed.

fix test assumption
