* Add GC Cancel/Stop (#568)Dan Engelbrecht2023-11-246-127/+293
| | | | - 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.
* reduce work when there are no blocks to compact (#558)Dan Engelbrecht2023-11-221-51/+54
| | | | * reduce work when there are no blocks to compact * fix lock scopes
* add command line options for compact block threshold and gc verbose (#557)Dan Engelbrecht2023-11-214-156/+232
| | | | | | | | | | | - Feature: Added new options to zenserver for GC V2 - `--gc-compactblock-threshold` GCV2 - how much of a compact block should be used to skip compacting the block, default is 90% - `--gc-verbose` GCV2 - enable more verbose output when running a GC pass - Feature: Added new options to `zen gc` command for GC V2 - `--compactblockthreshold` GCV2 - how much of a compact block should be used to skip compacting the block, default is 90% - `--verbose` GCV2 - enable more verbose output when running a GC pass - Feature: Added new parameters for endpoint `admin/gc` (PUT) - `compactblockthreshold` GCV2 - how much of a compact block should be used to skip compacting the block, default is 90% - `verbose` GCV2 - enable more verbose output when running a GC pass
* compact separate for gc referencer (#533)Dan Engelbrecht2023-11-216-631/+735
| | | | | - 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
* blocking queue fix (#550)Dan Engelbrecht2023-11-161-1/+1
| | | | | | | | | * make BlockingQueue::m_CompleteAdding non-atomic * ZenCacheDiskLayer::Flush logging * name worker threads in ZenCacheDiskLayer::DiscoverBuckets * name worker threads in gcv2 * improved logging in ZenServerInstance * scrub threadpool naming * remove waitpid handling, we should just call wait to kill zombie processes
* gc history log (#519)Dan Engelbrecht2023-11-132-8/+286
| | | | | - Feature: Writes a `gc.log` with settings and detailed result after each GC execution (version 2 only) - Break out file name rotate to allow access for gclog - CompactBinaryToJson(MemoryView Data, StringBuilderBase& InBuilder)
* 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
* disk layer gc and error/warnings cleanup (#515)Dan Engelbrecht2023-11-081-2/+2
| | | | | | | - Improvement: Use GC reserve when writing index/manifest for a disk cache bucket when disk is low when available - Improvement: Demote errors to warning for issues that are not critical and we handle gracefully - Improvement: Treat more out of memory errors from windows as Out Of Memory errors Fixed wrong sizeof() statement for compactcas index (luckily the two structs are of same size)
* spdlog implementation hiding (#498)Stefan Boberg2023-11-063-34/+24
| | | | | | | | | this change aims to hide logging internals from client code, in order to make it easier to extend and take more control over the logging process in the future. As a bonus side effect, the generated code is much tighter (net delta around 2.5% on the resulting executable which includes lots of thirdparty code) and should take less time to compile and link. Client usage via macros is pretty much unchanged. The main exposure client code had to spdlog internals before was the use of custom loggers per subsystem, where it would be common to have `spdlog::logger` references to keep a reference to a logger within a class. This is now replaced by `zen::LoggerRef` which currently simply encapsulates an actual `spdlog::logger` instance, but this is intended to be an implementation detail which will change in the future. The way the change works is that we now handle any formatting of log messages in the zencore logging subsystem instead of relying on `spdlog` to manage this. We use the `fmt` library to do the formatting which means the client usage is identical to using `spdlog`. The formatted message is then forwarded onto any sinks etc which are still implememted via `spdlog`.

* individual gc stats (#506)Dan Engelbrecht2023-10-306-357/+558
| | | | | - Feature: New parameter for endpoint `admin/gc` (GET) `details=true` which gives details stats on GC operation when using GC V2 - Feature: New options for zen command `gc-status` - `--details` that enables the detailed output from the last GC operation when using GC V2

* 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
