## Description This PR adds `iroh-sync`, a document synchronization protocol, to iroh, and integrates with `iroh-net`, `iroh-gossip` and `iroh-bytes`. * At the core is the `iroh-sync` crate, with a set reconciliation algorithm implemented by @dignifiedquire. See [the old iroh-sync repo](https://github.com/n0-computer/iroh-sync/) for the prehistory and #1216 for the initial PR (fully included in this PR, and by now outdated) * Iroh sync is integrated in the iroh node, with iroh-gossip, in the RPC interface, and the CLI. * `LiveSync` is the handle to an actor that integrates sync with [gossip](#1149 ) to broadcast and receive document updates from peers. For each open document a gossip swarm is joined with a `TopicId` derived from the doc namespace. * mod `download` contains the new downloader. It will be improved in #1344 . * mod `client` is the new high-level RPC client. It currently only has methods for dealing with docs and sync, other things should be added once we merged this. CLI commands for sync are in `commands/sync.rs`. Will be much better with #1356 . * `examples/sync.rs` has a REPL to modify and sync docs. It does a full setup without using the iroh console. Also includes code to sync directories, and a hammer command for load testing. * The PR also introduces `iroh::client::Iroh`, a wrapper around the RPC client, and `iroh::client::Doc`, a wrapper around RPC client for a single document ## Notes & open questions #### Should likely happen before merge: * [x] Make `iroh_sync::Store:::list_authors` and `list_replicas` return iterators `iroh-sync` *fixed in #1366 * * [ ] Add `iroh_sync::Store::close_replica` * [x] `ContentStatus` in `on_insert` callback is reported as `Ready` if the content is still `baomap::PartialEntry` (in-process download) *fixed in a8e8093* #### Can happen after merge, but before `0.6` release * [ ] Implement `AuthorImport` and `AuthorShare` RPC & CLI commands * [ ] sync store `list_namespaces` and `list_authors` internally collect, return iterator instead * [ ] Fix cross-compiles to arm/android. See cross-rs/cross#1311 * [ ] Ensure that fingerpring calculation is efficient and/or cached for large documents. Currently calculating the initial fingerprint iterates once over all entries in a document. * [ ] Make content downloads be more reliable * [ ] Add some way to download content from peers independent of the first insertion event for a remote entry. The downloader with retries is tracked in #1334 and 1344, but independent of that, we still would currently only ever try to queue a download when the `on_insert` callback triggers, which is only once. There should be a way, even if manual for now, to try to download missing content in a replica from peers. * [ ] during `iroh-sync` sync include info if content is available for each entry * [ ] Add basic peer management and persistence. Currently live sync will stop to do anything after a node restart. * [ ] Persist the addressbook of peers for a document, to reconnect when restarting the node * [ ] Implement `PeerAdd` and `PeerList` RPC & CLI commands. The latter needs changes in `iroh-net` to expose information of currently-connected peers and their peer info. * [ ] Make read-only replicas possible * [ ] Improve reliablity of replica sync. * sync is triggered on each `NeighborUp` event from gossip. check that we don't sync too much. * maybe include peer info in gossip messages, to queue syncs with those (but not all at once) * track and exchange the timestamp of last full sync for peers, to know if you missed gossiped message and react accordingly * add more tests with peers coming and leaving #### Open questions * [ ] `iroh_sync::EntrySignature` should the signatures include a namespace prefix? * [ ] do we want the 1:1 mapping of `NamespaceId`and gossip `TopicId`, or would the topic id as a hash be better? #### Other TODOs collected from the code * [ ] Port `hammer` and `fs` commands from REPL example to iroh cli * [ ] docs/naming: settle terminology about keypairs, private/secret/signing keys, public keys/identifiers and make docs and symbols consistent * [ ] Make `bytes_get` streaming in the RPC interface * [ ] Allow to unset the subscription on a replica * [ ] `iroh-sync` shouldn't depend on `iroh-bytes` only for `Hash` type -> #1354 * [ ] * [ ] Move `sync::live::PeerSource` to iroh-net or even better -> #1354 * [ ] `StoreInstance::put` propagate error and verify timestamp is reasonable. * [ ] `StoreInstance::get_range` implement inverted range * [ ] `iroh_sync`: Remove some items only used in tests (marked with #[cfg(test)]) * [ ] `iroh_sync` fs store: verify get method fetches all keys with this namespace * [ ] `ranger::SimpleStore::get_range`: optimize * [ ] `ranger::Peer` avoid allocs? * [ ] `fs::StoreInstance::get_fingerprint` optimize * [ ] `SyncEngine::doc_subscribe` remove unwrap, handle error ## Change checklist - [x] Self-review. - [x] Documentation updates if relevant. - [ ] Tests if relevant. --------- Co-authored-by: dignifiedquire <me@dignifiedquire.com> Co-authored-by: Asmir Avdicevic <asmir.avdicevic64@gmail.com> Co-authored-by: Kasey <klhuizinga@gmail.com>

We have a number of things that are common to all libs. E.g. utility functions and reexports. We have to be careful since these "common" crates often get quite fat, but I think it nevertheless be good to have one.
What we could do there would be to reexport crates so that we have a single place to do things like the blake3 -> iroh-blake3 change, and have generic utility functions like all the stuff related to progress.
