* zenserverprocess hardening (#61)Dan Engelbrecht2024-04-252-21/+40
| | | | * verify running process before creating event * make sure we don't signal/wait for a zenserver instance that we did not wait for to get ready

| | | | | | | | | | | * report down/up transfer speed during progress * add disk buffering in http client * offload block decoding and chunk writing form network worker pool threads add block hash verification for blocks recevied at oplog import * separate download-latch from write-latch to get more accurate download speed * check headers when downloading with http client to go directly to file writing for large payloads * we must clear write callback even if we only provide it as an argument to the Download() call * make timeout optional in AddSponsorProcess * check return codes when creating windows threadpool
* capture zenserver output on error (#51)Dan Engelbrecht2024-04-182-23/+86
| | | | * capture spawned server output and output on launch error * fix logging and launch validation in tests
* improved lock file handling (#50)Dan Engelbrecht2024-04-182-12/+122
| | | | | | | | | | | | - 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 Engelbrecht2024-04-172-10/+77
| | | | | | | | | | | | | - 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

* reinstate formatter settings for file sink (#631)Stefan Boberg2024-01-171-0/+9
| | | fixes issue introduced in #615
* release RPC recording memory early (#627)Stefan Boberg2023-12-201-2/+7
| | | previously the segment would call `clear()` on the `m_Entries` vector but this does not release the backing memory so we have to do the `swap` dance
* separate RPC processing from HTTP processing (#626)Stefan Boberg2023-12-203-0/+992
| | | | | | * moved all RPC processing from HttpStructuredCacheService into separate CacheRpcHandler class in zenstore * move package marshaling to zenutil. was previously in zenhttp/httpshared but it's useful in other contexts as well where we don't want to depend on zenhttp * introduced UpstreamCacheClient, this provides a subset of functions on UpstreamCache and lives in zenstore

| | | | | | | | | (#600) * Make sure that PathFromHandle don't hide true error when throwing exceptions * changelog * return error info in PathFromHandle if path fails to resolve
* multi-line logging improvements (#597)Stefan Boberg2023-12-112-72/+112
| | | | | | * 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 Boberg2023-12-061-4/+5
| | | | | | | 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
* safe threadpool shutdown (#584)Dan Engelbrecht2023-12-041-0/+6
| | | * shut down thread pools earlier to worker threads has a chance to terminate before main thread atexit
* global thread worker pools (#577)Dan Engelbrecht2023-11-292-0/+110
| | | - Improvement: Use two global worker thread pools instead of ad-hoc creation of worker pools
* fixed file logger pattern (#579)Stefan Boberg2023-11-291-1/+1
| | | | previously, the millisecond part was inexplicably logged after the date, not the time.
* optimized index snapshot reading/writing (#561)Stefan Boberg2023-11-274-11/+139
| | | | | 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
* moved process handling code into separate h/cpp (#555)Stefan Boberg2023-11-201-0/+1

* use dynamic port assignment for tests (#545)Stefan Boberg2023-11-172-44/+77
| | | this change replaces hard-coded port numbers in tests with dynamically assigned ports, to avoid potential issues around socket lifetimes and re-use policies

* gc history log (#519)Dan Engelbrecht2023-11-131-59/+10
| | | | | - 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)
* fix bad access to unlocked state (#527)Dan Engelbrecht2023-11-101-0/+1
| | | | * don't touch non-locked data when creating manifest * safety assert for test dir
* factored out some compiler definitions etc into zenbase (#517)Stefan Boberg2023-11-072-1/+3
| | | | | 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 Boberg2023-11-064-47/+186
| | | | | | | | | 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`.
* statsd for cas (#511)Dan Engelbrecht2023-11-061-0/+34
| | | | * separate statsd interfaces so they can be accessible to zenstore * statsd for cas
* 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
* added missing includes (#504)Stefan Boberg2023-10-274-0/+7
| | | | | 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
