| * add command line options for compact block threshold and gc verbose (#557)Dan Engelbrecht2023-11-2112-163/+332
| | | | | | | | | | | | | | | | | | | | | | - 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 Engelbrecht2023-11-2113-991/+1321
| | | | | | | | | | - 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
| * zen run command (#552)Stefan Boberg2023-11-2124-675/+605
| | | | | | | | | | | | | | | | | | | | initial version -- this is primarily intended to be used for running stress tests and/or benchmarks example usage: `zen run -n 10 -- zenserver-test` `zen run -n 10 -- zenserver-test --ts=core.assert` run zenserver-test 10 times (testing only the `core.assert` test suite) `zen run --time 600 --basepath=d:\test_dir\test1 -- zenserver-test` keeps spawning new instances for 10 minutes (600 seconds)
| * basic ZEN_ASSERT_FORMAT implementation (#556)Stefan Boberg2023-11-215-60/+131
| | | | | | includes porting some compact binary builder code to use it since it had vestiges of the UE-side asserts

| | | | | | | | | | | | | | | | * changed posix event implementation to use std::atomic instead of volatile * ensure Event::Close() can take lock before deleting the inner object * don't try to take the Event lock if the event is already signaled * changed logic around Event::Wait without time-out. this works around some apparent issues on MacOS/Linux * fix logic for posix process exit wait
| * add zenserver state snapshot support (#543)Stefan Boberg2023-11-166-2/+146
| | | | | | | | | | this introduces a --snapshot-dir command line option to zenserver which specifies a directory which will be propagated to the persistence root directory on start-up. This is most powerful with file systems which support block cloning, such as ReFS on Windows. This allows even very large state snapshots to be used repeatedly without having to worry about mutating the original dataset on disk. When using ReFS the state copy for even large state directories can be very fast since the duration is primarily proportional to the number of files in the tree rather than the size of the files being cloned. The storage requirements are also minimal as all data will be handled in a copy-on-write manner.

* gc history log (#519)Dan Engelbrecht2023-11-139-199/+535

* package dependency clean-ups (#531)Stefan Boberg2023-11-138-63/+16
| | | | | | | | | | this change just cleans up dependency declarations in xmake.lua files, discovered while exploring a more to xrepo which catches dependency problems since it will not just place all includes in a single directory, unlike vcpkg. * removed spurious asio dependency from zenserver-test * removed rocksdb reference * add missing asio package dependency * removed catch2 reference (no longer available) * added explicit cpr reference * made some zencore package dependencies public (this is necessary because some public zencore headers pull in package headers. If you use a more strict package manager than vcpkg then you get compilation errors whenever these includes are pulled in unless you declare the dependency explicitly)
* fmt compilation fix for fmt v10+new vs build (#529)Stefan Boberg2023-11-131-8/+15
| | | VS 17.7.6 triggers some new compilation errors with certain versions of fmt::make_format_args. This should fix those errors. I don't fully understand why this is necessary, sadly my c++-fu is not strong enough.

* reduce memory footprint for bucket indexes (#526)Stefan Boberg2023-11-101-14/+14
| | | reduces memory footprint of cache index by 10% or so by limiting the maximum number of entries in a bucket to 2^32 (was 2^64)

* disk layer gc and error/warnings cleanup (#515)Dan Engelbrecht2023-11-086-80/+131
| | | | | | | - 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)

* factored out some compiler definitions etc into zenbase (#517)Stefan Boberg2023-11-0734-343/+374
| | | | | this is a header-only library which mostly contains definitions to support different platforms and compilers. It is part of the zen codebase but is intended to be consumable separately to zenbase etc to support standalone transport plug-ins and similar.
* spdlog implementation hiding (#498)Stefan Boberg2023-11-0644-512/+820
| | | | | | | | | 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`.
* gc v2 tests (#512)Dan Engelbrecht2023-11-0612-171/+389

* fixed issue where file log sink would get the wrong pattern assigned (#513)Stefan Boberg2023-11-061-12/+12
| | | | this made the file log emit relative timing instead of an absolute timestamp prefix
