| | | | | | | | | | * Make object store endpoint S3 compatible. * Removed XML pretty printing and set object store endpoint disabled by default.

* 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
* keep a "null" iobuffer core to reduce redundant memory allocations (#507)Dan Engelbrecht2023-11-062-1/+7

* New GC implementation (#459)Dan Engelbrecht2023-10-301-3/+17
| | | - Feature: New garbage collection implementation, still in evaluation mode. Enabled by `--gc-v2` command line option
* 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
* only measure a variable integer once where we can (#500)Dan Engelbrecht2023-10-252-7/+19

* 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
* statsd metrics reporting (#496)Stefan Boberg2023-10-251-0/+1
| | | | | added support for reporting metrics via statsd style UDP messaging, which is supported by many monitoring solution providers this change adds reporting only of three cache related metrics (hit/miss/put) but this should be extended to include more metrics after additional evaluation

* Cache (rpc) activitity recording improvements (#482)Stefan Boberg2023-10-201-1/+1
| | | | | | | 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
* 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.
* minor fixes to zencore (#457)Stefan Boberg2023-10-094-8/+3

* reject known bad bucket names in structured cache (#452)v0.2.27-pre0Stefan Boberg2023-10-061-0/+13
| | | | | | | * 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 Boberg2023-10-051-2/+5
| | | | | | | | 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

* lua config file improvements (#379)Dan Engelbrecht2023-08-311-0/+4
| | | | | | - Bugfix: All options given on command line now overrides lua config file settings - Improvement: All options available from command line can now be configured in the lua config file (with a few exceptions such as `owner-pid`, `install` and `uninstall`) We can now also generate a Lua config (just string so far) that includes all options given on command line together with any optional Lua input config file. The idea here is to be able to save config options in the future.
