* per namespace/project cas prep refactor (#470)Dan Engelbrecht2025-08-201-109/+197
| | | | | | | - 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`

| * graceful wait in parallelwork destructor (#438)Dan Engelbrecht2025-06-161-1/+10
| | | | | | | | | | * exception safety when issuing ParallelWork * add asserts to Latch usage to catch usage errors * extended error messaging and recovery handling in ParallelWork destructor to help find issues
| * pause, resume and abort running builds cmd (#421)Dan Engelbrecht2025-06-051-3/+4
| | | | | | | | | | - 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

* | Change to PutResult structurezousar2025-06-241-32/+57
| | | | | | | | Result structure contains status and a string message (may be empty)
* | Establish TODOs and unit test for rejected PUT propagationzousar2025-03-241-0/+3

* | Enforce Overwrite Prevention According To Cache Policyzousar2025-02-261-29/+59
|/ | | | 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.
* jupiter code cleanup (#276)Dan Engelbrecht2025-01-221-1/+1
| | | | | | | * cleanup jupiter * move jupiter files to separate folder * CloudCache -> Jupiter * split up jupiter files * kill redundant JupiterAccessTokenProvider

| | | | | | move jupiter.h/cpp -> zenutil move packageformat.h/.cpp -> zenhttp zenutil now depends on zenhttp instead of the inverse
* Memory tracking improvements (#262)Stefan Boberg2024-12-111-0/+4
| | | | | * added LLM tag to properly tag RPC allocations * annotated some more httpsys functions with memory tags * only emit memory scope events if the active tag is different from the new tag
* global open process cache for projectstore (#257)Dan Engelbrecht2024-12-051-1/+3
| | | | * move openprocess cache to central location * enable openprocesscache in projectstore so "getchunks" can send filehandles when requested

| | | | | | * 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
* bucket size queries (#203)Dan Engelbrecht2024-10-211-0/+115
| | | - Feature: Added options --bucketsize and --bucketsizes to zen cache-info to get data sizes in cache buckets and attachments
* Added namespace qualifier (optional) for z$ rpc requests (#166)Stefan Boberg2024-09-231-51/+74
| | | 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.
* cache optimizations (#88)Dan Engelbrecht2024-05-301-1/+1
| | | | | * message formatting optimizations * bump iostorecompression small value threshold to 1MB
* fix zero size attachment replies (#69)Dan Engelbrecht2024-05-021-1/+9

| | | - Improvement: Batch scope for put of cache values
* InsertChunks for CAS store (#55)Dan Engelbrecht2024-04-221-30/+47
| | | - Improvement: Add batching when writing multiple small chunks to block store - decreases I/O load significantly on oplog import

| | | | | | | - Improvement: Add zenhttp-test and zenutil-test - Improvement: Moved cachepolicy test to cachepolicy.cpp - Improvement: Renamed cachestore tests from z$ to cachestore - Improvement: Moved test linking so test for a lib is linked by <lib>-test - Improvement: Removed HttpRequestParseRelativeUri in httpstructuredcache.cpp and use the one in cacherequests.h instead
* remove reference caching (#658)Dan Engelbrecht2024-02-271-1/+0
| | | * remove reference caching
* changed RPC recording to MPSC setup (#638)Stefan Boberg2024-01-311-21/+1
| | | fixes rare race condition when using RPC recording for long periods of time
* separate RPC processing from HTTP processing (#626)Stefan Boberg2023-12-201-1576/+33
| | | | | | * 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
* move cachedisklayer and structuredcachestore into zenstore (#624)Stefan Boberg2023-12-191-1/+1
|
* cache RPC recorder threading fixes (#617)Stefan Boberg2023-12-191-15/+56
| | | | | * ensure all access to m_Entries is done while holding lock * RPC recorder concurrency fixes - setup/teardown of recorder needs to be done while holding an exclusive lock. Calls into recorder should be done while holding a shared lock.
* fixed missing context for cache record PUT operations (#503)Stefan Boberg2023-10-271-2/+6
|
* merge disk and memory layers (#493)Dan Engelbrecht2023-10-241-23/+59
| | | | - Feature: Added `--cache-memlayer-sizethreshold` option to zenserver to control at which size cache entries get cached in memory - Changed: Merged cache memory layer with cache disk layer to reduce memory and cpu overhead
* Cache (rpc) activitity recording improvements (#482)Stefan Boberg2023-10-201-6/+19
| | | | | | | this adds a new RPC recording path aimed at more continuous recording and analysis of recorded sessions the new strategy is implemented alongside the original in order to retain the ability to read the older format the main difference between v2 and v1 is that the new strategy splits the recording into segments which are independent from each other. This is done to enable long running sessions with automatic disk cleanup (not implemented yet), appending to an existing recording (not implemented) and/or partial analysis and processing. The recorder will start a new segment when some criteria is fulfilled, including the number of files in the segment directory, disk footprint etc
* cache reference tracking (#455)Dan Engelbrecht2023-10-101-77/+108
| | | | | - Feature: Add caching of referenced CId content for structured cache records, this avoid disk thrashing when gathering references for GC - disabled by default, enable with `--cache-reference-cache-enabled` - Improvement: Faster collection of referenced CId content in project store

* move badrequest count back to old scope for compatability with Zen DashboardDan Engelbrecht2023-09-281-2/+1
|
* adding more stats (#429)Dan Engelbrecht2023-09-281-26/+158
| | | | | - Feature: Add detailed stats on requests and data sizes on a per-bucket level, use parameter `cachestorestats=true` on the `/stats/z$` endpoint to enable - Feature: Add detailed stats on requests and data sizes on cidstore, use parameter `cidstorestats=true` on the `/stats/z$` endpoint to enable - Feature: Dashboard now accepts parameters in the URL which is passed on to the `/stats/z$` endpoint
* prefer to handle cache RPC requests synchronously (#428)Stefan Boberg2023-09-271-4/+17
| | | | | * only handle RPC requests in a worker thread if we have an upstream. we may as well handle the request inline on the http_io thread if we're only dealing with local data since the response times should be pretty consistent in that case * http.sys: don't create async worker thread pool until it's needed (typically only if we have an upstream)
* Add runtime status/control of logging (#419)Dan Engelbrecht2023-09-221-2/+6
| | | | | | | | | | | - Feature: New endpoint `/admin/logs` to query status of logging and log file locations and cache logging - `enablewritelog`=`true`/`false` parameter to control cache write logging - `enableaccesslog`=`true`/`false` parameter to control cache access logging - `loglevel` = `trace`/`debug`/`info`/`warning`/`error` - Feature: New zen command `logs` to query/control zen logging - No arguments gives status of logging and paths to log files - `--cache-write-log` `enable`/`disable` to control cache write logging - `--cache-access-log` `enable`/`disable` to control cache access logging - `--loglevel` `trace`/`debug`/`info`/`warning`/`error` to set debug level
