| | | * gcv2 tests for project store and bugfixes
* optimized index snapshot reading/writing (#561)Stefan Boberg2023-11-271-6/+25
| | | | | the previous implementation of in-memory index snapshots serialise data to memory before writing to disk and vice versa when reading. This leads to some memory spikes which end up pushing useful data out of system cache and also cause stalls on I/O operations. this change moves more code to a streaming serialisation approach which scales better from a memory usage perspective and also performs much better
* Add GC Cancel/Stop (#568)Dan Engelbrecht2023-11-241-114/+141
| | | | - GcScheduler will now cancel any running GC when it shuts down. - Old GC is rather limited in *when* it reacts to cancel of GC. GCv2 is more responsive.
* compact separate for gc referencer (#533)Dan Engelbrecht2023-11-211-21/+86
| | | | | - Refactor GCV2 so GcReferencer::RemoveExpiredData returns a store compactor, moving out the actual disk work from deleting items in the index. - Refactor GCV2 GcResult to reuse GcCompactStoreStats and GcStats - Make Compacting of stores non-parallell to not eat all the disk I/O when running GC
* don't try to close NewBlockFile if it hasn't been created (#523)Dan Engelbrecht2023-11-081-1/+1
| | | * Don't try to close NewBlockFile if it hasn't been created

| | | | | this change adds some includes to files which "inherit" includes from elsewhere this was exposed on another branch when removing some heavy dependencies from central headers
* Remove any unreferenced blocks in block store on open (#492)Dan Engelbrecht2023-10-231-4/+21
| | | * Remove any unreferenced blocks in block store on open
* Don't prune block locations due to missing blocks a startup (#487)Dan Engelbrecht2023-10-201-39/+90
| | | | | | * 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)
* check that block does not exists on disk before starting write to it (#449)Dan Engelbrecht2023-10-051-18/+44

* 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
