Release of Slurm-web v5.1.0

[rezib]

Added

• gateway:
  • Support loading LDAP bind password from separate file (Support password files for LDAP authentication #585). Contribution from @Cornelicorn.
  • Add cache boolean in /clusters response to indicate whether cache service is enabled on agents.
  • Add /agent/{cluster}/cache/stats route to reverse proxy request to agent /cache/stats.
• agent:
  • Record slurmrestd cache hit and miss counts in cache service.
  • Add metrics with cache hit and miss counts.
  • Support querying cache metrics.
  • Add cache boolean in /info endpoint to indicate whether cache service is enabled on agent.
  • Add /cache/stats route to retrieve cache statistics.
• ldap-check: Support loading LDAP bind password from separate file. Contribution from @Cornelicorn.
• conf:
  • Add gateway [ldap]>bind_password_file configuration parameter. Contribution from @Cornelicorn.
  • Add gateway [ldap]>lookup_as_user configuration parameter. Contribution from @Cornelicorn.
  • Introduce cache-view authorization action.
  • Assign cache-view action to user role (all authenticated users) in default authorization policy.

Changed

• gateway:
  • Check agent version is greater or equal to the minimal supported version specified in gateway configuration settings.
  • Send asynchronous HTTP requests to discover agents (Replace all requests calls by aiohttp in gateway #438).
  • After successful user authentication, when service bind dn and password are defined in configuration, Slurm-web now retrieves user information and user groups in LDAP with these credentials by default. Previous behavior can be restored by setting lookup_as_user = yes under the [ldap] section in gateway configuration file (Groups are not fetched in LDAP authentication if users can't query groups #587). Contribution from @Cornelicorn.
• agent:
  • Change route to information endpoint from /v{version}/info to /info.
  • Return version of agent in information endpoint.
  • Emit warning log entry when SlurmwebMetricsDBError is raised before responding HTTP/500.
• conf: Update description of agent > version gateway parameter to describe its new semantic.
• pkgs:
  • Set Python requests external library dependency on agent only.
  • Bump minimal version of RFL.authentication to v1.5.0.
  • Move Python aiohttp external library dependency from gateway extra package to main package because it is also a dependency of the agent now.
• docs:
  • Update authorization policy reference documentation.
  • Update configuration reference documentation.
  • Mention cache metrics in metrics configuration reference documentation.

Fixed

• gateway: Handle content type error when expecting JSON response from agent.
• agent: Return HTTP/501 instead of crashing when metrics are requested but metrics service is disabled.
• front:
  • Handling of GPU declared without model in Slurm configuration (Resources page does not show nodes in "Up" status #584). Contribution from @mehalter.
  • Regression on handling of denied clusters in cluster list.
  • Parsing of GRES GPUs when comma is present between brackets with indexes or sockets. Contribution from @astappiev.
  • Fix color of ring in clusters list in dark mode.
  • Update dependencies to fix CVE-2025-5889 (brace-expansion).
• docs: Fix rendering of example list values in generated configuration reference documentation (LDAP restricted group in doc #599).
