- Upgrades @multiformats/multiaddr to 11.0.0
- Removes ipfs-http-client and delegate router dependencies
- Test delegation using interface stubs instead of implementations
* fix: add successful stream peer to protobook
If a protocol stream has been successfully negotiated and is to be
psased to the application, the peerstore should ensure that the peer is
registerd with that protocol.
* fix: upgrader test fix
Updates all deps needed to support passing lists of byte arrays where they have been created from multiple input buffers.
When reading multiplexed data, all messages arrive in length-prefixed buffers, which means the first few bytes tell the consumer how many bytes long next chunk will be.
One length prefixed chunk can be delivered in several payloads from the underlying network transport. The first payload can also include the length prefix and some or all of the data, so we stitch these together in a `Uint8ArrayList` to avoid having to concatenate `Uint8Array`s together.
Previously once we'd received enough bytes to satisfy the length prefix we'd concatenate the bytes together, but this is a potentially expensive operation where transports have small message sizes so instead just pass the `Uint8ArrayList` to the consumer and let them decide wether to concatenate or not as some consumers will be smart enough to operate on lists of `Uint8Array`s instead of always requiring a contiguous block of memory.
BREAKING CHANGE: Streams are now `Duplex<Uint8ArrayList, Uint8ArrayList | Uint8Array>`
- If a stream is opened that exceeds inbound/outbound limits, reset that stream (if it is incoming) or abort and throw (if it is outgoing)
- Make the error message more helpful (say which protocol has breached the limit)
- Increase the default stream limits so we don't trigger this by accident when a remote dials us with a protocol we don't support
Ensure that we don't wait forever for upgrading an inbound connection
to occur.
Note that transports should return an AbortableSource when passed an
AbortSignal so outbound connections to not need the same fix.
Also adds default timeouts for the ping, fetch, and identify protocols.
* feat: limit protocol streams per-connection
Uses the `maxInboundStreams` and `maxOutboundStreams` of the `registrar.handle`
opts to limit the number of concurrent streams open on each connection
on a per-protocol basis.
Both values default to 1 so some tuning will be necessary to set
appropriate values for some protocols.
* chore: make error codes consistent
* chore: fix up examples
If an error is thrown during the initial stages of setting up a multiplexed stream, ensure we close the stream to free up any resources associated with it.
There are a few places in the codebase where we send/receive data from the network without timeouts/abort controllers which means the user has to wait for the underlying socket to timeout which can take a long time depending on the platform, if at all.
This change ensures we can time out while running identify (both flavours), ping and fetch and adds tests to ensure there are no regressions.
**Motivation**
In lodestar, when we handle "peer:connect" event, we dial the peer which gives another "peer:connect" event and it causes other issues
**Motivation**
In `onConnect` function, "peer:connect" event should be emitted after we add connection to the `connections` map so that when app dial the peer in "peer:connect" event handler, it uses the same/existing connection
Converts this module to typescript.
- Ecosystem modules renamed from (e.g.) `libp2p-tcp` to `@libp2p/tcp`
- Ecosystem module now have named exports
- Configuration has been updated, now pass instances of modules instead of classes:
- Some configuration keys have been renamed to make them more descriptive. `transport` -> `transports`, `connEncryption` -> `connectionEncryption`. In general where we pass multiple things, the key is now plural, e.g. `streamMuxer` -> `streamMuxers`, `contentRouting` -> `contentRouters`, etc. Where we are configuring a singleton the config key is singular, e.g. `connProtector` -> `connectionProtector` etc.
- Properties of the `modules` config key have been moved to the root
- Properties of the `config` config key have been moved to the root
```js
// before
import Libp2p from 'libp2p'
import TCP from 'libp2p-tcp'
await Libp2p.create({
modules: {
transport: [
TCP
],
}
config: {
transport: {
[TCP.tag]: {
foo: 'bar'
}
},
relay: {
enabled: true,
hop: {
enabled: true,
active: true
}
}
}
})
```
```js
// after
import { createLibp2p } from 'libp2p'
import { TCP } from '@libp2p/tcp'
await createLibp2p({
transports: [
new TCP({ foo: 'bar' })
],
relay: {
enabled: true,
hop: {
enabled: true,
active: true
}
}
})
```
- Use of `enabled` flag has been reduced - previously you could pass a module but disable it with config. Now if you don't want a feature, just don't pass an implementation. Eg:
```js
// before
await Libp2p.create({
modules: {
transport: [
TCP
],
pubsub: Gossipsub
},
config: {
pubsub: {
enabled: false
}
}
})
```
```js
// after
await createLibp2p({
transports: [
new TCP()
]
})
```
- `.multiaddrs` renamed to `.getMultiaddrs()` because it's not a property accessor, work is done by that method to calculate announce addresses, observed addresses, etc
- `/p2p/${peerId}` is now appended to all addresses returned by `.getMultiaddrs()` so they can be used opaquely (every consumer has to append the peer ID to the address to actually use it otherwise). If you need low-level unadulterated addresses, call methods on the address manager.
BREAKING CHANGE: types are no longer hand crafted, this module is now ESM only
