* don't do full cb-object validation on cache records when read from disk (#739)Dan Engelbrecht2026-01-291-10/+9
| | | * don't do full cb-object validation on cache records when read from disk
* Ensure upstream put propagation includes overwritezousar2025-12-191-5/+12
| | | | When changing the default limit-overwrite behavior, a unit test surfaced a bug where an put of data with overwrite cache policy would not get propagated via zen's built-in upstream mechanism with a matching overwrite cache policy to the upstream. This change ensures that it does and leaves the unit test configured to exercise this scenario.
* batch op not in destructor (#676)Dan Engelbrecht2025-12-041-2/+17
| | | | | * use fixed vectors for batch requests * refactor cache batch value put/get to not execute code that can throw execeptions in destructor * extend test with multi-bucket requests
* automatic scrub on startup (#667)Dan Engelbrecht2025-11-271-1/+4
| | | | | - Improvement: Deeper validation of data when scrub is activated (cas/cache/project) - Improvement: Enabled more multi threading when running scrub operations - Improvement: Added means to force a scrub operation at startup with a new release using ZEN_DATA_FORCE_SCRUB_VERSION variable in xmake.lua
* RawOffset can be anything and we expect an empty buffer to be returned along ↵Dan Engelbrecht2025-11-261-17/+23
| | | | with RawSize = 0 if the offset was out of bounds for the value. (#666)
* cacherequests helpers test only (#551)Dan Engelbrecht2025-10-031-3/+2
| | | | * don't use cacherequests utils in cache_cmd.cpp * make zenutil/cacherequests code into test code helpers only
* GetCacheChunk value request respects RawHash (#518)Zousar Shaker2025-09-291-1/+3
| | | When requesting a value via the GetCacheChunks rpc method, if the request specified a raw hash, only return a hit if the raw hash matches what was in the cache.
* Improvement to Incomplete Result Iterationzousar2025-09-251-2/+1
| | | | From review feedback
* Report Incomplete Records To Clientzousar2025-09-241-5/+39
| | | | When requesting partial records, report back when a record is incomplete via an "Incomplete" array of bools that is a sibling to the "Result" array for batch/rpc operations, or via the HttpResponseCode::PartialContent status code for individual record requests.
* Adjust the responses from PUT commandszousar2025-09-231-2/+2
| | | | | - Ensure that text responses are in a field named "Message" - Change the record response to be named "Record" instead of "Object"
* Change batch put responses for client reportingzousar2025-09-191-20/+44
| | | | Conflicts are now treated as successes, and we optionally return a Details array instead of an ErrorMessages array. Details are returned for all requests in a batch, or no requests in a batch depending on whether there are any details to be shared about any of the put requests. The details for a conflict include the raw hash and raw size of the item. If the item is a record, we also include the record as an object.

* per namespace/project cas prep refactor (#470)Dan Engelbrecht2025-08-201-17/+37
| | | | | | | - Refactor so we can have more than one cas store for project store and cache. - Refactor `UpstreamCacheClient` so it is not tied to a specific CidStore - Refactor scrub to keep the GC interface ScrubStorage function separate from scrub accessor functions (renamed to Scrub). - Refactor storage size to keep GC interface StorageSize function separate from size accessor functions (renamed to TotalSize) - Refactor cache storage so `ZenCacheDiskLayer::CacheBucket` implements GcStorage interface rather than `ZenCacheNamespace`

| | | | | | | | | | | | * Added EASTL to help with eliminating memory allocations * Applied EASTL to eliminate memory allocations, primarily by using `fixed_vector` et al to use stack allocations / inline struct allocations Reduces memory events in traces by close to a factor of 10 in test scenario (starting editor for project F)

|/ | | | Overwrite with differing value should be denied if QueryLocal is not present and StoreLocal is present. Overwrite with equal value should succeed regardless of policy flags.

* Added namespace qualifier (optional) for z$ rpc requests (#166)Stefan Boberg2024-09-231-1/+16
| | | This change adds support for a namespace-qualified RPC endpoint for z$ at `/z$/<namespace>/$rpc` which may be used to validate RPC requests by URL inspection. The old scheme is still supported.

* moved all RPC processing from HttpStructuredCacheService into separate CacheRpcHandler class in zenstore * move package marshaling to zenutil. was previously in zenhttp/httpshared but it's useful in other contexts as well where we don't want to depend on zenhttp * introduced UpstreamCacheClient, this provides a subset of functions on UpstreamCache and lives in zenstore
