Summary

Requests sent by OCA\Files_Sharing\External\Storage to remote servers, including the shareinfo request and the reachability checks (e.g. against status.php or ocm-provider), rely on a hardcoded 10-second timeout. For large federated shares, the remote server may take longer to respond to shareinfo. The request then fails with cURL error 28 and the share is reported as unavailable, with no way to adjust the limit (as reported in #29941).

This change introduces the sharing.federation.request_timeout system configuration option (in seconds, defaulting to 10), which applies to both timeout and connect_timeout for these requests, and documents it in config.sample.php. The default value preserves the existing behavior. WebDAV requests for the same storage are unaffected and continue to use davstorage.request_timeout.

How to test

1. Create a federated share from a remote server whose /index.php/apps/files_sharing/shareinfo takes more than 10 seconds to answer (e.g. a big share, or a remote that delays the response by 15 s).
2. Accept the share and open it.
   • Before: getShareInfo() fails after 10 s with cURL error 28: Operation timed out after 10000 milliseconds.
3. occ config:system:set sharing.federation.request_timeout --type=integer --value=20 and open it again.
   • After: the request completes (about 15 s in my test).
4. Without the key the behavior is unchanged (fails after 10 s).

Unit test: apps/files_sharing/tests/ExternalStorageTest.php.
