* more cbobject validations (#527)Dan Engelbrecht2025-09-291-5/+19
| | | - Improvement: Add additional validations when reading disk cache records to get references in GC
* Adjust the responses from PUT commandszousar2025-09-231-10/+5
| | | | | - 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 reportingzousar2025-09-191-11/+24
| | | | 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.
* add EMode to WorkerTheadPool to avoid thread starvation (#492)Dan Engelbrecht2025-09-101-3/+4
| | | - Improvement: Add a new mode to worker thread pools to avoid starvation of workers which could cause long stalls due to other work begin queued up. UE-305498
* per namespace/project cas prep refactor (#470)Dan Engelbrecht2025-08-201-12/+16
| | | | | | | - 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`
* reduce lock contention when checking for disk cache put reject (#465)Dan Engelbrecht2025-08-121-91/+81
| | | | keep rawsize and rawhash if available when using batch for inline puts keep rawsize and rawhash of input value if we have calculated it for validation already

| * pause, resume and abort running builds cmd (#421)Dan Engelbrecht2025-06-051-4/+8
| | | | | | | | | | - Feature: `zen builds pause`, `zen builds resume` and `zen builds abort` commands to control a running `zen builds` command - `--process-id` the process id to control, if omitted it tries to find a running process using the same executable as itself - Improvement: Process report now indicates if it is pausing or aborting

|/ | | | 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.

* Miscellaneous minor LLM fixes (#268)v5.5.17-pre0Stefan Boberg2024-12-171-0/+2
| | | | | | | With this change, LLM tags are assigned using the name,parent tuple rather than just by name only. This allows tag hierarchies like `cache/store` and `project/store` which would previously get collapsed into the first pair seen when registering the `store` tag. This PR also adds some more LLM tag annotations to more accurately associate memory allocations with subsystems In addition, this PR also tweaks the frequency of timer marker events to increase the resolution in Insights and avoid some cases of Insights deciding that marker events are too far apart since we don't allocate as frequently as UE tends to.
* Builds API remote project store (#258)Dan Engelbrecht2024-12-121-2/+2
| | | Feature: zen command oplog-export and oplog-import now supports --builds remote target using the Jupiter builds API
* Unity build fixes (#253)Stefan Boberg2024-12-051-41/+52
| | | some fixes to make everything build using unity build mode. Mostly moved code from anonymous namespaces into local impl namespace to avoid ambiguity in name resolution.
* added support for dynamic LLM tags (#245)Stefan Boberg2024-12-021-0/+15
| | | | | * added FLLMTag which can be used to register memory tags outside of core * changed `UE_MEMSCOPE` -> `ZEN_MEMSCOPE` for consistency * instrumented some subsystems with dynamic tags
* caller controls threshold for bulk-loading chunks in IterateChunks (#222)Dan Engelbrecht2024-11-251-2/+3
| | | | | | * Allow caller to control threshold for bulk-loading chunks in IterateChunks * use smaller batch chunk reading for /fileinfos and /chunkinfos as we do not intend to read the payload * use smaller batch read buffer when just querying for size of attachments
* oplog prep gc fix (#216)Dan Engelbrecht2024-11-151-10/+13
| | | | | | - Added option gc-validation to zenserver that does a check for missing references in all oplog post full GC. Enabled by default. - Feature: Added option gc-validation to zen gc command to control reference validation. Enabled by default. - Added more details in post GC log. - Fixed race condition in oplog writes which could cause used attachments to be incorrectly removed by GC
* memory leak fix (GetBatchHandle) (#215)Stefan Boberg2024-11-081-0/+4
| | | This fixes a memory leak which would cause stale handles to accumulate until process shutdown. Each cache get operation would therefore leak some memory.
* bucket size queries (#203)Dan Engelbrecht2024-10-211-12/+54
| | | - Feature: Added options --bucketsize and --bucketsizes to zen cache-info to get data sizes in cache buckets and attachments

* optimize gc reference sort (#179)Dan Engelbrecht2024-10-011-4/+3
| | | | | - Do a single call to mempcy when fetching attachments from the meta store in GC - Use small lambda when calling std::sort in FilterReferences (enables inlining of the comparision function) - Use a single function for < and == comparision in KeepUnusedReferences
* gc command attachment options (#176)Dan Engelbrecht2024-09-301-3/+4
| | | * zen command - add options to control meta data cache when triggering gc
* optimize startup time (#175)Dan Engelbrecht2024-09-301-8/+15
| | | | | | * use tsl::robin_set for BlockIndexSet don't calculate full block location when only block index is needed * don't copy visitor function * reserve space for attachments
