* improved assert (#37)Dan Engelbrecht2024-04-049-31/+427
| | | | - Improvement: Add file and line to ASSERT exceptions - Improvement: Catch call stack when throwing assert exceptions and log/output call stack at important places to provide more context to caller
* compressed header reading opt (#33)Dan Engelbrecht2024-04-031-52/+86
| | | * refactor so we don't have to re-read data from source to get block sizes
* Faster reading of compressed buffer headers by not materializing entire ↵Dan Engelbrecht2024-03-281-22/+52
| | | | source buffer (#28)
* add yaml serialization support (#3)Stefan Boberg2024-03-266-783/+1191
| | | | | | | this change adds serialization of payloads as YAML, but not parsing. The implementation is somewhat based on the JSON path, and may be collapsed eventually as it is possible to serialize JSON format using the same code it also separates out the JSON serialization into a separate file for ease of maintenance any HTTP request response may be formatted as yaml by using a `.yaml` suffix or an `Accept: text/yaml` header

* ensure we can build without trace (#619)Stefan Boberg2023-12-192-0/+5
| | | | `xmake config -zentrace=n` would previously not build cleanly
* various TSAN/ASAN/LeakAnalyzer fixes (#622)Stefan Boberg2023-12-194-9/+24
| | | | | | | | | * fix JobQueue test threading issue.

* fix leak in IoBuffer for manifested small chunk (#618)Stefan Boberg2023-12-191-2/+2
| | | | * fix leak in IoBuffer for manifested small chunk. previously it would null out the `m_DataPtr` member on every path from `IoBufferExtendedCore::~IoBufferExtendedCore()` but it only really makes sense to null it out when the buffer has been memory mapped

| * Make sure that PathFromHandle don't hide true error when throwing exceptions ↵Dan Engelbrecht2023-12-111-6/+6
| | | | | | | | | | | | | | | | | | (#600) * Make sure that PathFromHandle don't hide true error when throwing exceptions * changelog * return error info in PathFromHandle if path fails to resolve

| | | | | | this adds information on program name and command line to trace initialization
| * improved scrubbing of oplogs and filecas (#596)Stefan Boberg2023-12-111-0/+13
| | | | | | | | | | | | - Improvement: Scrub command now validates compressed buffer hashes in filecas storage (used for large chunks) - Improvement: Added --dry, --no-gc and --no-cas options to zen scrub command - Improvement: Implemented oplog scrubbing (previously was a no-op) - Improvement: Implemented support for running scrubbint at startup with --scrub=<options>
| * multi-line logging improvements (#597)Stefan Boberg2023-12-111-0/+8
| | | | | | | | | | | | * added ZEN_SCOPED_WARN and implemented multi-line logging * changed so file log also uses `fullformatter` for consistency and to get the multi-line support across the board
| * SuppressConsoleLog now removes any existing console logger (#599)Stefan Boberg2023-12-111-0/+5
| | | | | | SuppressConsoleLog now removes any existing console logger to avoid exceptions in spdlog
| * logging configuration via command line options (#589)Stefan Boberg2023-12-062-0/+81
| | | | | | | | | | | | | | with these changes it is possible to configure loggers on the command line. For instance: `xmake run zenserver --log-trace=http_requests,http` will configure the system so that the `http_request` and `http` loggers are set to TRACE level
| * HTTP plugin request debug logging (#587)Stefan Boberg2023-12-052-0/+15
| | | | | | | | | | | | * added log level control/query to LoggerRef * added debug logging to http plugin implementation * added GetDebugName() to transport plugin interfaces * added debug name to log output
| * global thread worker pools (#577)Dan Engelbrecht2023-11-292-0/+4
| | | | | | - Improvement: Use two global worker thread pools instead of ad-hoc creation of worker pools
| * close thread pool + parallel CasImpl::Initialize (#576)Dan Engelbrecht2023-11-281-0/+1
| | | | | | | | * close thread pool at destruction * parallell casimpl::initialize

| | | | | | | | controlled manner (#573)
| * optimized index snapshot reading/writing (#561)Stefan Boberg2023-11-273-2/+28
| | | | | | | | | | 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
| * fix block cloning copy argument validation (#560)Stefan Boberg2023-11-221-0/+30

| * compact separate for gc referencer (#533)Dan Engelbrecht2023-11-211-0/+18
| | | | | | | | | | - 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 Boberg2023-11-214-2/+185
| | | | | | | | | | | | | | | | | | | | 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 Boberg2023-11-214-58/+127
| | | | | | includes porting some compact binary builder code to use it since it had vestiges of the UE-side asserts

| * blocking queue fix (#550)Dan Engelbrecht2023-11-162-26/+11
| | | | | | | | | | | | | | | | | | * 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
| * further posix event improvements (#549)Stefan Boberg2023-11-161-6/+23
| | | | | | | | | | | | | | | | * 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 Boberg2023-11-162-1/+98
| | | | | | | | | | 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.
