  3. feat: expose the full wantlist through GetWantlist 

    And expose a separate function for _just_ getting want-blocks. When the user
runs `ipfs bitswap wantlist`, they expect to see everything the node is
currently looking for.

  1. feat: remove the context from the donthavetimeoutmanager (ipfs#303) 

    This removes one goroutine per peer which tends to be a pretty big deal. This
brings go-ipfs down from 5.5 to 4.5 goroutines per peer.

  1. fix: minimize time holding wantlist lock (ipfs#361) 

    * fix: minimize time holding wantlist lock

Instead of holding the lock the entire time we prepare a message, hold the lock
while we retrieve the wantlist entries, process the entries without the lock,
retake the lock, then mark entries as sent.

This means:

1. We never sort entries while holding the lock.
2. We allocate exactly three times while holding the lock (once per entry list).

* fix: address code review

This deduplicates some state and allows us to do less book-keeping for broadcast
wants. We should probably rename the PeerManager to the WantManager and rename the
WantManager to something else.

  1. fix: avoid taking accessing the peerQueues without taking the lock 

    Or, really, just avoid accessing it. We don't need it.

This caused a concurrent map access panic under load.

  1. fix: don't say we're sending a full wantlist unless we are (ipfs#429) 

    I'm not sure why we set "full" to true here, but this could be the source of a
whole bunch of bidirectional sync issues. That is, if two peers are syncing off
each other, they could repeatedly "reset" each other's wantlist to "empty".

  1. Added WithScoreLedger Bitswap option (ipfs#430) 

    * Separate decision engine ledger on two parts: score and the wantlist

This is the first step to make external decision logic (tagging
peers with score values) possible.

The wantlist still resides in the original `ledger` struct while
sent/received byte accounting and scores are extracted to the new
`scoreledger` struct managed by the original `scoreWorker()` logic.
The accounting is integrated into the `Engine` via `ScoreLedger`
interface making it possible to replace the original `scoreWorker()`
with some other logic. The interface, however, doesn't allow a
score logic to directly touch peer tags: the logic may decide about
score values while tagging itself is still under control of Engine.

Note: with this commit it's yet not possible to replace the original
score logic because there is no public methods for that.

* Added "WithScoreLedger" Bitswap option

New `WithScoreLedger(decision.ScoreLedger)` option in the `bitswap`
package is the way to connect a custom `ScoreLedger` implementation
to the decision engine. The `Engine` now has the corresponding
`UseScoreLedger(ScoreLedger)` method.

The `ScoreLedger` and `ScorePeerFunc` types are exposed from the
internal `decision` package to the public one.

Because its options are processed by the `Bitswap` after construction
of its parts but before starting of the engine, the default
`scoreLedger` initialization is moved from `newEngine()` to
`StartWorkers()`.

New `TestWithScoreLedger` test is added. The test checks for start and
stop of the testing score ledger implementation that is specified via
`WithScoreLedger` option.

* Combine score ledger start with initialization of the score function

Having a separate `Init(ScoreFunc)` method seems redundant (thx
@dirkmc for pointing about that). As a bonus, the two-step ledger
starting process is now enclosed in the `startScoreLedger()` function.

* Let's call Stop() to stop a ScoreLedger

The `Close()` method was there to stop the ledger. Let call it
`Stop()` now.

* Get return of the blank Receipt out of conditional block

Explicitly form it as the final resort.

  1. Fix: Increment stats.MessagesSent in msgToStream() function (ipfs#441) 

    * Share common code between network/ipfs_impl_test.go tests

Extract the code that is common in TestMessageResendAfterError,
TestMessageSendTimeout and TestMessageSendNotSupportedResponse to a
separate function.

* Make prepareNetwork() return two hosts and two networks

Let prepareNetwork() make simmetric setup with two `ErrHost`s
with two `impl` networks to be sure we test `impl` instances on
both ends.

* Added TestNetworkCounters test to the "network" package

The test shows we have a problem with `MessagesSent` counter.

* Fix: Increment stats.MessagesSent in msgToStream() function

Fixes the bug with incrementing `MessagesSent` counter only in
`SendMessage()` method if `impl`. Now it works for `MessageSender`
too.

* Allow to specify a network event listener for tests

Added `listener network.Notifiee` to the `receiver` structure.
If a listener is specified then `prepareNetwork()` connects it
to the mock network it builds before making any connections.

* Wait for all network streams are closed in testNetworkCounters

Wait for all network streams are closed instead of just using a
timeout. The timeout of 5 s is still used as a deadline (it makes
the test to fail).

* Fix: Close the MessageSender in testNetworkCounters()

The `MessageSender` needs to be closed if we want all streams in
the network to be closed.

* Fix: Close MessageSender in other tests too

  1. Add WireTap interface (ipfs#444) 

    * Add WireTap interface

WireTap interface can be used to access all messages send and received
by Bitswap. This can be used to implement advanced statistics/analysis
logic, which is beyond scope of Bitswap, but can be implemented as IPFS
plugin.

Some examples of potential applications:
 - per CID bandwidth tracker (see: https://gitcoin.co/issue/PinataCloud/apollo/2/100023631)
 - detailed per peer stats
 - intrusion detection system (IDS) implementation

* Add test for WireTap

  10. fix: Nil dereference while using SetSendDontHaves 

    This option is used by the benchmark to simulate the old bitswap
comportement.

This follows the same refactoring idea as done in 22e7099.

It was crashing since it was trying to access the `sendDontHaves`
property of `bs.engine` but `bs.engine` is initialized right after
the options are applied, not before.

  17. introduce a ledger that stores which peers are waiting for a Cid 

    When receiving a new block (Engine.ReceiveFrom), we shouldn't have to loop over
all peers in order to determine if they need this block. Instead, use a map to
save which peers are waiting for a give Cid.

  1. More stats, knobs and tunings (ipfs#514) 

    * add configurability options for TaskWorkerCount and EngineTaskWorkerCount,
* add option for maximum outstanding bytes per peer
* add prometheus metrics for how long it takes to send messages, the number of pending and active tasks, and the number of pending and active block tasks
* add many of the unexported defaults to a defaults subpackage of the internal package

* feat: tighter send timeouts

1. Minimum timeout of 10s.
2. We add 2s due to latencies.
3. Minimum bandwidth of 100kbit/s.
4. Maximum message send time of 2min (way more time than necessary).

  1. feat: add basic tracing (ipfs#562) 

    This adds tracing spans to the costly Bitswap entry points. It doesn't
instrument the bitswap internals, which will take some time. In
go-ipfs, this will at least let us know the contribution of Bitswap to
the overall request handling time.

This also plumbs contexts through internally so that they reach the
content routing APIs, so that traces are propagated through and we can
start instrumenting e.g. the DHT.

This has several benefit:
- untangle the code
- allow to use an exchange as pure block retrieval
- avoid double add

  1. test: remove TestTracer 

    This test is exceptionally racy and IMO useless (you can go read the 10 lines of code making up tracing and convaince yourself it's working.)

  1. chore: update go-libp2p v0.22.0 

    This remove the github.com/libp2p/go-libp2p-loggables because AFAIT this is not usefull anymore (we use tracing now).

If people care about uuids in logs, we should log sessions in go-log instead.

  1. bitswap: mark all hybrid, client, server and network tests flaky 

    I've applied the jackhammer approach, there is probably correct tests in
this set, but I'll leave finding them (and fixing bad ones) to someone
else (including potentially future me).

To enable flaky tests pass RUN_FLAKY_TESTS=1 environement variable.
