This adds a new routing mechanism for sync workers that resolves access tokens to usernames via Synapse's whoami endpoint, enabling true user-level sticky routing regardless of which device or token is used. Previously, sticky routing relied on parsing the username from native Synapse tokens (`syt_<base64 username>_...`), which only works with native Synapse auth and provides device-level stickiness at best. This new approach works with any auth system (native Synapse, MAS, etc.) because Synapse handles token validation internally. Implementation uses nginx's auth_request module with an njs script because: - The whoami lookup requires an async HTTP subrequest (ngx.fetch) - js_set handlers must return synchronously and don't support async operations - auth_request allows the async lookup to complete, then captures the result via response headers into nginx variables The njs script: - Extracts access tokens from Authorization header or query parameter - Calls Synapse's whoami endpoint to resolve token -> username - Caches results in a shared memory zone to minimize latency - Returns the username via a `X-User-Identifier` header The username is then used by nginx's upstream hash directive for consistent worker selection. This leverages nginx's built-in health checking and failover.

# This is a custom nginx configuration file that we use in the container (instead of the default one),
|
|
# because it allows us to run nginx with a non-root user.
|
|
#
|
|
# For this to work, the default vhost file (`/etc/nginx/conf.d/default.conf`) also needs to be removed.
|
|
#
|
|
# The following changes have been done compared to a default nginx configuration file:
|
|
# - various temp paths are changed to `/tmp`, so that a non-root user can write to them
|
|
# - the `user` directive was removed, as we don't want nginx to switch users
|
|
|
|
# load_module directives must be first or nginx will choke with:
|
|
# > [emerg] "load_module" directive is specified too late.
