The `namespaced_cache` module is pretty generic and can be moved to proxmox.git (maybe in proxmox-shared-cache) once it has sufficiently stabilized. Changes since the RFC: - change storage location to /run/proxmox-datacenter-manager/api-cache - change name of pdm_cache to api_cache - use freestanding functions in api_cache - add async interface - minor code style improments - improve test coverage and documentation - add basic sanity checks for namespaces and keys (e.g. prohibiting ../) - add cleanup code for the old remote-updates cachefile Thanks to Dominik C. and Wolfgang for their reviews of the RFC, highly appreciated! proxmox-datacenter-manager: Lukas Wagner (4): add persistent, generic, namespaced key-value cache implementation add api_cache as a specialized wrapper around the namespaced cache api: resources: subscriptions: switch over to api_cache remote-updates: switch over to new api_cache Cargo.toml | 1 + debian/control | 1 + server/Cargo.toml | 4 + server/src/api/pve/mod.rs | 4 +- server/src/api/remotes/updates.rs | 4 +- server/src/api/resources.rs | 81 +- server/src/api_cache.rs | 126 +++ .../bin/proxmox-datacenter-privileged-api.rs | 9 +- server/src/lib.rs | 2 + server/src/namespaced_cache.rs | 742 ++++++++++++++++++ server/src/remote_updates.rs | 87 +- 11 files changed, 962 insertions(+), 99 deletions(-) create mode 100644 server/src/api_cache.rs create mode 100644 server/src/namespaced_cache.rs Summary over all repositories: 11 files changed, 962 insertions(+), 99 deletions(-) -- Generated by murpp 0.12.0
