* Make sure we monitor for new project, oplogs, namespaces and buckets during ↵Dan Engelbrecht2024-06-131-0/+10
| | | | | | GCv2 (#93) - Bugfix: Make sure we monitor and include new project/oplogs created during GCv2 - Bugfix: Make sure we monitor and include new namespaces/cache buckets created during GCv2
* cache optimizations (#88)Dan Engelbrecht2024-05-302-2/+15
| | | | | * message formatting optimizations * bump iostorecompression small value threshold to 1MB
* workspace shares (#84)Dan Engelbrecht2024-05-291-0/+2
| | | Feature: New 'workspaces' service which allows a user to share a local folder via zenserver. A workspace can have mulitple workspace shares and they provie an HTTP API that is compatible with the project oplog HTTP API. Workspaces and shares are preserved between runs. Workspaces feature is disabled by default - enable with --workspaces-enabled option when launching zenserver.

| | | | * capture spawned server output and output on launch error * fix logging and launch validation in tests
* improved lock file handling (#50)Dan Engelbrecht2024-04-181-1/+2
| | | | | | | | | | | | - Feature: `zen down` - --`data-dir` to specify a data directory to deduce which zen instance to bring down - Feature: `zen attach` - --`data-dir` to specify a data directory to deduce which zen instance to attach to222 - Feature: `zen status` - --`port` filter running zen instances based on port - --`data-dir` filter running zen instances based on information in the data directory - Improvement: Trying to load a compact binary object from an empty file no longer causes access violation
* zen startup hardening (#49)Dan Engelbrecht2024-04-171-1/+4
| | | | | | | | | | | | | - Feature: `zen up` command improvements - --`port` allows you to specify a base port when starting an instance - --`base-dir` allows you to specify a base directory for the zenserver executable if it is not located next to the zen.exe executable - Feature: `zen down` - --`port` allows you to specify a base port when shutting down an instance - --`base-dir` allows you to specify a base directory for the zenserver executable if it is not located next to the zen.exe executable - --`force` if regular shutdown fails it tries to find a running zenserver.exe process and terminate it - If it fails to attach to the running server it now waits for it to exit when setting the RequestExit shared memory flag - Improvement: zenserver now checks the RequestExit flag in the shared memory and exist gracefully if it is set - Improvement: When adding a sponsor process to a running zenserver instance, we wait for it to be picked up from the shared memory section to determine success/fail
* Validate input buffer size when trying to parse package message (#47)Dan Engelbrecht2024-04-131-1/+12

* add yaml serialization support (#3)Stefan Boberg2024-03-261-2/+30
| | | | | | | 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

* special treatment large oplog attachments v2 (#5)Dan Engelbrecht2024-03-141-4/+6
| | | | | - Bugfix: Install Ctrl+C handler earlier when doing `zen oplog-export` and `zen oplog-export` to properly cancel jobs - Improvement: Add ability to block a set of CAS entries from GC in project store - Improvement: Large attachments and loose files are now split into smaller chunks and stored in blocks during oplog export

| | | jobqueue - add AbortReason and properly propagate error when running async command

| | | | the previous implementation was quite slow due to use of mt and uniform_distribution.
* ensure we can build without trace (#619)Stefan Boberg2023-12-191-0/+1
| | | | `xmake config -zentrace=n` would previously not build cleanly
* various TSAN/ASAN/LeakAnalyzer fixes (#622)Stefan Boberg2023-12-191-1/+6

| * added details to trace initialization (#588)Stefan Boberg2023-12-111-2/+2
| | | | | | 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
| * logging configuration via command line options (#589)Stefan Boberg2023-12-061-0/+4
| | | | | | | | | | | | | | 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 Boberg2023-12-051-0/+3
| | | | | | | | | | | | * 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 Engelbrecht2023-11-291-0/+1
| | | | | | - Improvement: Use two global worker thread pools instead of ad-hoc creation of worker pools
| * optimized index snapshot reading/writing (#561)Stefan Boberg2023-11-272-0/+5
| | | | | | | | | | 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
| * 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 Boberg2023-11-212-0/+7
| | | | | | | | | | | | | | | | | | | | 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)
