* fixed issue in compactcas.restart test due to std::vector<bool> (#559)Stefan Boberg2025-10-061-2/+5
| | | `std::vector<bool>` is a special container since it bit packs the values rather than just using an array of booleans. This means that updating it on multiple threads simultaneously is dangerous

| | | | | | | | | | | | * faster FileSystemTraversal test * faster jobqueue test * faster NamedEvent test * faster cache tests * faster basic http tests * faster blockstore test * faster cache store tests * faster compactcas tests * more responsive zenserver launch * tweak worker pool sizes in tests

| | | | | - 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

| | | | | | | | | - **EXPERIMENTAL** `zen builds` - Feature: `--zen-cache-host` option for `upload` and `download` operations to use a zenserver host `/builds` endpoint for storing build blob and blob metadata - Feature: New `/builds` endpoint for caching build blobs and blob metadata - `/builds/{namespace}/{bucket}/{buildid}/blobs/{hash}` `GET` and `PUT` method for storing and fetching blobs - `/builds/{namespace}/{bucket}/{buildid}/blobs/putBlobMetadata` `POST` method for storing metadata about blobs - `/builds/{namespace}/{bucket}/{buildid}/blobs/getBlobMetadata` `POST` method for fetching metadata about blobs - `/builds/{namespace}/{bucket}/{buildid}/blobs/exists` `POST` method for checking existance of blobs
* Miscellaneous minor LLM fixes (#268)v5.5.17-pre0Stefan Boberg2024-12-171-1/+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.

| | | Feature: Project store "getchunks" rpc call /prj/{project}/oplog/{log}/rpc extended to accept both CAS (RawHash) and Id (Oid) identifiers as well as partial ranges
* Unity build fixes (#253)Stefan Boberg2024-12-051-13/+13
| | | 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/+34
| | | | | * 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
* use plain sorted array instead of map of vectors (#237)Dan Engelbrecht2024-11-271-4/+7
| | | | | * use plain sorted array instead of map of vectors * reserve vectors up front = 5% perf increase * don't do batch read of chunks if we have a single chunk -> 1% perf gain
* caller controls threshold for bulk-loading chunks in IterateChunks (#222)Dan Engelbrecht2024-11-251-3/+5
| | | | | | * 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
* stronger validation of payload existance (#229)Dan Engelbrecht2024-11-251-2/+26
| | | | | | - Don't add RawSize and Size in ProjectStore::GetProjectFiles response if we can't get the payload - Use validation of payload size/existance in all chunk fetch operations in file cas - In project store oplog validate, make sure we can reach all the payloads - Add threading to oplog validate request
* fix inconsistencies in filecas due to failing to remove payload file during ↵Dan Engelbrecht2024-11-221-1/+1
| | | | | | | | GC (#224) make sure we rewrite filecas entries if chunk size changes (due to compression changes) hardening of move/write files in filecas if we encounter a filecas entry with mismatching size (due to pre-existing bug) we validate the file and update the index if we find a bad filecas file on disk we now attempt to remove it
