Offline RPC #3866

sudo-shashank · 2024-01-11T14:55:58Z

Summary of changes

Changes introduced in this pull request:

Set up offline RPC server: that serves data from CAR file and does not connect to the Filecoin network.
Added serve subcommand: forest-tool api serve [CAR_FILE] command runs an RPC server.
Download a latest snapshot if no snapshot file is provided.
RPC port defaults to 2345 which can be configured using --port flag
CI test

Reference issue to close (if applicable)

Closes #3812

Change checklist

I have performed a self-review of my own code,
I have made corresponding changes to the documentation,
I have added tests that prove my fix is effective or that my feature works (if possible),
I have made sure the CHANGELOG is up-to-date. All user-facing changes should be reflected in this document.

Could we refactor the creation of the server?

+
+# Function to get the number of files in the present working directory
+num_files_here() {
+    find . -type f | wc --lines


nit: this overcounts if I make a file with a newline in the name

fixed, now directly using the path returned from snapshot fetch

+    done
+
+    # Check if services on ports 8080 and 8081 have started
+    while ! (nc -z localhost 8080 && nc -z localhost 8081); do


nit: this could be an until loop
also hardcoding the ports here defeats the purpose of using the PORTS array

right, fixed

+    result="$($FOREST_TOOL_PATH api compare "$snapshot" --forest /ip4/127.0.0.1/tcp/8080/http --lotus /ip4/127.0.0.1/tcp/8081/http)"
+
+    # Check the result
+    if echo "$result" | tail -n +3 | grep -E -v "\| *(Valid|Timeout) *\| *(Valid|Timeout) *\|"; then


Parsing the output is an odd choice - can we not modify forest-tool api compare to give us useful exit codes?

wibni: a module structure that ditches the common suffix use rpc::api::auth rather than rpc::auth_api

i would like to do this in a separate PR

have I seen this code before? Could we refactor?

Yeah, it would be really great to have a single "helper" method for all the occurrences of RPC definitions, assuming they are all the same. If not - perhaps whatever is shared is a good start.

Something like:

fn rpc_methods(server: Arc<Server>) or otherwise we could define a custom trait and implement it for the Server struct, see extension traits for inspiration.

Ah, I can see now that this is RPC v1. As opposed to v0 or ws. Curious if there is already a definition for that elsewhere.

+            crate::cli_shared::snapshot::stable_url(TrustedVendor::default(), &chain)?;
+        let tmp_snapshot_path = tempfile::Builder::new().tempdir()?.into_path();


/tmp typically has 10GB size limit which is insufficient for downloading a mainnet snapshot

I think we could just keep the logic simple, ask users to download a snapshot via forest-tool snapshot fetch

Or use logic similar to that of the running node? Seems laborious having to download snapshots manually..

I agree with roman, I think we should keep the automatic snapshot download feature if a snapshot is not provided

Yeah, but you have to take into account Hailong's comment about tmp dir size.

Shall we add some prompt before downloading? Like in other places

yes i'll add a similar prompt

Thanks, then I guess we also need a similar --force or --yes option to bypass the prompt
