23.03.1

Features

• Add --recursive option to cancel all the dependent sessions to session terminate API (#893)
• The new mock-accelerator plugin supsedes the cuda-mock plugin. It may be set to have arbitrary accelerator resource slots. Existing developers who use the cuda-mock plugin should update their mockup device list configuration (cuda-mock.toml) to follow the new format (mock-accelerator.toml). (#1158)
• Utilization checker returns thresholds_check_operator. (#1202)
• Fix SCP/SFTP not working (#1225)
• Add support for idle checking ATOM accelerators (#1234)
• Add is_public field to scaling_group table. (#1236)
• Add agent public-host config option and impl manager API to fetch direct access info of SYSTEM kernel. (#1238)
• Make image scanner handle OCI image metadata formats (#1241)
• Do not count stakes of SYSTEM role kernels when calculating resource occupancy (#1243)
• Update /folder/_/list-hosts API to expose client scaling groups designated only for SSH connection apps (#1246)
• Add system_SSH_image config to webserver so that system-role ssh image used to support fast scp and sftp in file browser dialog can be specified. (#1250)
• Fix destroying session on behalf of other user by providing owner_access_key not working (#1255)

Improvements

• Improve status_data generation when the debug mode is enabled (#1203)

Fixes

• Calculate idle checker's remaining time to expire correctly. (#1205)
• Fix relative path computation in the NetApp storage backend and disable cross-volume vfolder cloning until we have explicit export/import abstractions for the storage backends (#1208)
• Optimize monthly stat API by reducing the number of iteration and fetch to Redis. (#1214)
• Remove DoSyncKernelStatsEvent events since it is deprecated and adjust the interval of agent heart-beat event through configuration. (#1223)
• Consume kernel lifecycle events and remove manager.registry.kernel_creation_tracker. (#1224)
• Disable collecting per-container statistics on macOS backend until #1230 is resolved (#1231)
• fix minor typo error in mock-accelerator config (#1240)
• Fix logical errors in the fallback process for cpuset detection in agents when the docker API is not available (#1248)
• Upgrade aiotools to 1.6.1 for potential memory leak fix when there are unhandled exceptions inside persistent task groups (#1256)

Miscellaneous

• Bump base Python version from 3.11.2 to 3.11.3 to resolve potential bugs. (#1227)
• Replace ./pants with the scie-pants project so that developers could use a much faster version of pants binary bootstrapper that auto-installs the required Python interpreter using a static build (#1237)
