| | | | m_LastLightweightGcDuration stats (#494)
* Remove any unreferenced blocks in block store on open (#492)Dan Engelbrecht2023-10-233-8/+24
| | | * Remove any unreferenced blocks in block store on open
* Don't prune block locations due to missing blocks a startup (#487)Dan Engelbrecht2023-10-203-90/+102
| | | | | | * Don't prune block locations due to missing blocks a startup This makes the behaviour consistent with FileCas - you can have an index that is not fully backed by data. Asking for a location that is not backed by data results in getting an empty result back Also, don't try to GC blocks that are unknown to the block store at the time of snapshot (to avoid removing data that comes in after GatherReferences in GC)
* Cache (rpc) activitity recording improvements (#482)Stefan Boberg2023-10-201-4/+0
| | | | | | | 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

* skip lightweight GC if full GC is due soon (#467)Stefan Boberg2023-10-121-20/+30

* refactor comapactcas index (#443)Dan Engelbrecht2023-10-042-19/+62

* Remove ATL header usage (#306)Stefan Boberg2023-05-151-4/+4
| | | ATL has been used here and there as a convenience. Given that this is a legacy component and not always something which gets installed along with the compiler we hereby remove the dependency altogether in favour of our own simple wrappers
* fix logic for old blocks in blockstore gc (#295)Dan Engelbrecht2023-05-121-21/+24
| | | | | | | * fix logic for old blocks in blockstore gc If we will remove all entries in a block and keep nothing we can't expect for the block to exist. If we want to keep entries in a block, the block must exist, if not error and move entries to delete list. Don't reset output block between blocks we are reading from, keep using it until it exceeds the max limit. * changelog
