* 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
* reject bad bucket reads (#456)Stefan Boberg2023-10-091-1/+1
| | | | * extended bad bucket rejection logic to include GET operations as well as PUTs
* reject known bad bucket names in structured cache (#452)v0.2.27-pre0Stefan Boberg2023-10-061-1/+2
| | | | | | | * added string_view helpers for ParseHexBytes/ParseHexNumber * reject known bad buckets in structured cache put handler (32-character hex bucket names are rejected) * also added bucket rejection logic to bucket discovery * added rejected_writes stat to HttpStructuredCache
* fix HandleRpcRequest::WriteResponseAsync trace scope when we are not running ↵Dan Engelbrecht2023-10-041-1/+2
| | | | async
* Correctly calculate the total number of RPC ops in the stats page for ↵Dan Engelbrecht2023-09-291-2/+2
| | | | | structured cache (#433) Change "chunks" title to "count" for RPC chunk requests in stats page for structured cache
* 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
* add more trace scopes (#362)Dan Engelbrecht2023-09-151-115/+160
| | | | | * more trace scopes * Make sure ReplayLogEntries uses the correct size for oplog buffer * changelog
* More statistics for Cache, Project Store and Cid Store (#405)Dan Engelbrecht2023-09-141-5/+53

* Restructured structured cache store (#314)Stefan Boberg2023-05-171-0/+3209
This change separates out the disk and memory storage strategies into separate cpp/h files to improve maintainability.
