* various TSAN/ASAN/LeakAnalyzer fixes (#622)Stefan Boberg2023-12-194-9/+24
| | | | | | | | | * fix JobQueue test threading issue. The inner job queued with `QueueJob` would reference `I` from inside the captured closure which would subsequently disappear * made sure application exit is thread safe * don't try to access string data out of bounds * keep-alive flag is accessed from multiple threads * fix memory leaks in Zen upstream client code * TSAN fixes for Event
* 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
* implement cache recording segment split by age (#611)Stefan Boberg2023-12-142-5/+83
| | | - also fixes weird DateTime/TimeSpan comparison operator
* Make sure IoBuffer is a valid null-buffer after move operation (#610)Dan Engelbrecht2023-12-141-4/+13

| * 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
| * added details to trace initialization (#588)Stefan Boberg2023-12-112-7/+13
| | | | | | 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

| | | | | | | | | | | | * 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.

* gc history log (#519)Dan Engelbrecht2023-11-134-18/+215
| | | | | - 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)
* package dependency clean-ups (#531)Stefan Boberg2023-11-131-6/+10
| | | | | | | | | | 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.

* disk layer gc and error/warnings cleanup (#515)Dan Engelbrecht2023-11-081-0/+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)
* implemented openssl-free encryption for Windows (#520)Stefan Boberg2023-11-082-13/+192
| | | trims 40% off the (Windows) executable size
* factored out some compiler definitions etc into zenbase (#517)Stefan Boberg2023-11-0716-576/+44
| | | | | 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 Boberg2023-11-067-169/+488
| | | | | | | | | 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 Engelbrecht2023-11-063-8/+49
| | | | | | | | | | * set MaxBlockCount at init * properly calculate total size * basic blockstore compact blocks test * correct detection of block swap * Use one implementation for CreateRandomBlob * reduce some data sets to increase speed of tests * reduce test time * rename BlockStoreCompactState::AddBlock -> BlockStoreCompactState::IncludeBlock

* added missing includes (#504)Stefan Boberg2023-10-271-0/+2
| | | | | 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

* eliminate redundant logging code (#499)Stefan Boberg2023-10-252-1/+14
| | | | | | | | | zenutil and zenserver both contain very similar logging setup code and this change aims to make them have most code in common. * fullformatter/jsonformatter/RotatingFileSink are moved into dedicated header files in zenutil * zenserver `InitializeLogging`/`ShutdownLogging` are renamed `InitializeServerLogging`/`InitializeServerLogging` * these now call into the common zenutil `BeginInitializeLogging`/`FinishInitializeLogging` in addition to setting up server custom logging * `std::filesystem::path` is now logged after stripping any `\\\\?\\` prefix for readability
