Fixes #13642

worker_main_http_uri is a setting used by a worker yaml config file to direct a worker to proxy the /keys/upload endpoint to the main process. Instead of using a proxy, send the request to main by way of http replication.

To-do:

  • Build a new replication http servlet based on ReplicationUserDevicesResyncRestServlet because keys are ultimately about devices anyways.
  • Add conditional to main process KeyUploadServlet to use replication if a worker.
  • Strip out the old proxy version of KeyUploadServlet that was defined in generic_worker.py, just going to use the existing one for the main process. This functionality is now carried by the replication http servlet.
  • Overly long Docstring(please check me for accuracy).
  • Update configuration manual to include deprecation of setting.

Some odd things happened while I was working on this. While poking around and trying to figure out replication http, I missed filling out the _serialize_payload() function overload. Sytest correctly caught this and errored. Complement did not. Why? There is only one test for this /keys/upload endpoint, if the request got no information(it's a post request), then shouldn't it have errored since it would not have gotten a user_id nor a device_id(apparently not getting an actual set of keys doesn't matter as the response only sends back a count of whatever onetime_keys it finds and not some kind of acknowledgement).

We probably want to note that the configuration setting can be removed (and maybe log a deprecation notice if it is set? I don't know how folks feel about that)

Update docs, ok. The other, no idea how to do that.

Can we log a warning if "worker_main_http_uri" in config?

Something like "The config option worker_main_http_uri is unused since Synapse 1.72. It can be safely removed from your configuration."

This must happen on master so that the results can be correctly cached in
the database and streamed to workers.( Is this accurate?)

I suspect the point is:

  • for now, there must be exactly one worker writing keys (to avoid write races)
  • we haven't found the key writing to be heavy enough that it needs pulling off the master worker
  • so it's written by the master.

I guess that specifically the "cached in the database and streamed to workers." is the part I wanted to make sure was accurate. This is a copy-paste dangler. The Replication HTTP Servlet itself does no caching of it's own(the CACHE modifier is set to False below)

Broadly speaking, the database doesn't cache anything; it is the authoritative source of truth for the state of the homeserver. The application maintains various in-memory caches of the database's data. Workers typically receive cache invalidation messages over redis rather than new updates.

Request format(borrowed and expanded from KeyUploadServlet):

POST /_synapse/replication/upload_keys_for_user

{
"user_id": "<user_id>",
"device_id": "<device_id>",
"keys": {
"device_keys": {
"user_id": "<user_id>",
"device_id": "<device_id>",
"valid_until_ts": <millisecond_timestamp>,
"algorithms": [
"m.olm.curve25519-aes-sha2",

"keys": {
"<algorithm>:<device_id>": "<key_base64>",

Response is equivalent to ` /_matrix/client/v3/keys/upload`

KeyUploadServlet presumably refers to client/keys.py and not generic_worker (whose KeyUploadServelet was removed above).

I think it makes more sense to

  • update the docstring for KeyUploadServelet with your changes
  • have this docstring point us to that one. "See KeyUploadServelet for format of the request body and response body."
  • keep the POST /_synapse/replication/upload_keys_for_user line here

Yeah, it's slightly different though. Because of the passing of the information in the _serialize_json() _serialize_payload() includes having the user_id and the device_id which isn't part of the same request as the original prepended to the beginning of the request...(I think). Plus it wraps it into a keys object as well.
