| | | | mostly useful when reporting errors
* Don't prune block locations due to missing blocks a startup (#487)Dan Engelbrecht2023-10-205-147/+113
| | | | | | * Don't prune block locations due to missing blocks a startup This makes the behaviour consistent with FileCas - you can have an index that is not fully backed by data. Asking for a location that is not backed by data results in getting an empty result back Also, don't try to GC blocks that are unknown to the block store at the time of snapshot (to avoid removing data that comes in after GatherReferences in GC)
* Cache (rpc) activitity recording improvements (#482)Stefan Boberg2023-10-209-96/+816
| | | | | | | this adds a new RPC recording path aimed at more continuous recording and analysis of recorded sessions the new strategy is implemented alongside the original in order to retain the ability to read the older format the main difference between v2 and v1 is that the new strategy splits the recording into segments which are independent from each other. This is done to enable long running sessions with automatic disk cleanup (not implemented yet), appending to an existing recording (not implemented) and/or partial analysis and processing. The recorder will start a new segment when some criteria is fulfilled, including the number of files in the segment directory, disk footprint etc
* clean up GcContributor and GcStorage to be pure interfaces (#485)Dan Engelbrecht2023-10-2010-46/+31

* Add --skip-delete option to gc command (#484)Dan Engelbrecht2023-10-207-2/+23
| | | | - Feature: Add `--skip-delete` option to gc command - Bugfix: Fix implementation when claiming GC reserve during GC
* add `flush` command and more gc status info (#483)Dan Engelbrecht2023-10-1813-68/+345
| | | | | | - Feature: New endpoint `/admin/flush ` to flush all storage - CAS, Cache and ProjectStore - Feature: New command `zen flush` to flush all storage - CAS, Cache and ProjectStore - Improved: Command `zen gc-status` now gives details about storage, when last GC occured, how long until next GC etc - Changed: Cache access and write log are disabled by default
* added command line option to start server clean (#481)Stefan Boberg2023-10-174-30/+48

| * added logging utility functions (from sb/proto) (#469)Stefan Boberg2023-10-122-0/+549
| | | | | | these allow standalone programs to share much of the logging setup from zenserver
| * skip lightweight GC if full GC is due soon (#467)Stefan Boberg2023-10-121-20/+30
| | | | | | | | | | | | GC will now skip a lightweight GC if a full GC is due to run within the next lightweight GC interval also fixed some minor typos
| * adjust resource usage for dedicated servers (#466)Stefan Boberg2023-10-127-26/+84
| | | | | | | | | | | | | | | | | | when dedicated mode is enabled via `--dedicated` or `server.dedicated` then we tune http.sys server settings to be more suitable for a shared server initially we tune two things * the thread pool used to service I/O requests allows a larger number of threads to be created when needed. The minimum thread count is unchanged but in dedicated server mode we double the maximum number of threads allowed * the http.sys request queue length (`HttpServerQueueLengthProperty`) is increased to 50,000 in dedicated mode. The regular default is 1,000
* | Change default port to 8558zousar2023-10-119-13/+13
|/ | | | Changes the default port without altering config for shared instances.
* added explicit implementation of IoHash equals operator (#464)Stefan Boberg2023-10-111-0/+2
| | | | | | | | | * added explicit implementation of IoHash equals and less than operator using memcpy This improves codegen on MSVC in particular. Without this the operator is not inlined and consists of 20 individual (not in a loop) byte-by-byte comparisons each with an associated branch. With this change we get three comparisons (two uint64, one uint32) and three branches. So less pressure on branch predictors and as the code gets inlined the predictor should hopefully also function better.
* pluggable asio transport (#460)Stefan Boberg2023-10-1116-117/+607
| | | | | | | | | added pluggable transport based on asio. This is in an experimental state and is not yet a replacement for httpasio even though that is the ultimate goal also moved plugin API header into dedicated part of the tree to clarify that it is meant to be usable in isolation, without any dependency on zencore et al moved transport implementations into dedicated source directory in zenhttp note that this adds code to the build but nothing should change at runtime since the instantiation of the new code is conditional and is inactive by default
* hide HttpAsioServer interface behind factory function (#463)Stefan Boberg2023-10-113-24/+29

* updated plugin API class names (#462)Stefan Boberg2023-10-119-98/+97

* remove legacy compute interfaces (#461)Stefan Boberg2023-10-1112-3212/+41

|
* experimental pluggable transport support (#436)Stefan Boberg2023-10-1015-42/+2039
| | | this change adds a `--http=plugin` mode where we support pluggable transports. Currently this defaults to a barebones blocking winsock implementation but there is also support for dynamic loading of transport plugins, which will be further developed in the near future.
* cache reference tracking (#455)Dan Engelbrecht2023-10-109-188/+598
| | | | | - Feature: Add caching of referenced CId content for structured cache records, this avoid disk thrashing when gathering references for GC - disabled by default, enable with `--cache-reference-cache-enabled` - Improvement: Faster collection of referenced CId content in project store
* fixed GC logging output stats (#458)Stefan Boberg2023-10-101-1/+1

* reject known bad bucket names in structured cache (#452)v0.2.27-pre0Stefan Boberg2023-10-066-8/+82
| | | | | | | * added string_view helpers for ParseHexBytes/ParseHexNumber * reject known bad buckets in structured cache put handler (32-character hex bucket names are rejected) * also added bucket rejection logic to bucket discovery * added rejected_writes stat to HttpStructuredCache
* ZenCacheMemoryLayer should always store values using memory buffers (#451)Stefan Boberg2023-10-052-5/+9
| | | | | | | | this change fixes a problem where the memory cache layer can inadvertently prevent underlying block store files from being deleted * ensure we get memory buffers on all paths * added more context to error in IoBufferBuilder::ReadFromFileMaybe * fixed problematic pread call success check in IoBufferBuilder::ReadFromFileMaybe which would always report failure on Linux/MacOS
* fixed issue where IoBufferBuilder::ReadFromFileMaybe loses content type (#450)Stefan Boberg2023-10-052-2/+4
