* Miscellaneous minor LLM fixes (#268)v5.5.17-pre0Stefan Boberg2024-12-172-3/+5
| | | | | | | With this change, LLM tags are assigned using the name,parent tuple rather than just by name only. This allows tag hierarchies like `cache/store` and `project/store` which would previously get collapsed into the first pair seen when registering the `store` tag. This PR also adds some more LLM tag annotations to more accurately associate memory allocations with subsystems In addition, this PR also tweaks the frequency of timer marker events to increase the resolution in Insights and avoid some cases of Insights deciding that marker events are too far apart since we don't allocate as frequently as UE tends to.
* added test verification of XXH3_128Stream vs XXH3_128::HashMemoryStefan Boberg2024-12-131-0/+2

* split zencore/memory.h -> memoryview.h, memcmp.h (#228)Stefan Boberg2024-11-2518-51/+65
| | | | | | | minor clean-up `zencore/memory.h` used to contain a variety of things including `Malloc` support along with `MemoryView` etc since the memory allocator stuff moved into `zencore/memory/memory.h` there was basically only `MemoryView` and `MemCmp` in there which seemed better to split out into separate headers to avoid overloading `memory.h`
* Insights-compatible memory tracking (#214)Stefan Boberg2024-11-2545-100/+5946
| | | | | | | | | | | | | This change introduces support for tracing of memory allocation activity. The code is ported from UE5, and Unreal Insights can be used to analyze the output. This is currently only fully supported on Windows, but will be extended to Mac/Linux in the near future. To activate full memory tracking, pass `--trace=memory` on the commandline alongside `--tracehost=<ip>` or `-tracefile=<path>`. For more control over how much detail is traced you can instead pass some combination of `callstack`, `memtag`, `memalloc` instead. In practice, `--trace=memory` is an alias for `--trace=callstack,memtag,memalloc`). For convenience we also support `--trace=memory_light` which omits call stacks. This change also introduces multiple memory allocators, which may be selected via command-line option `--malloc=<allocator>`: * `mimalloc` - mimalloc (default, same as before) * `rpmalloc` - rpmalloc is another high performance allocator for multithreaded applications which may be a better option than mimalloc (to be evaluated). Due to toolchain limitations this is currently only supported on Windows. * `stomp` - an allocator intended to be used during development/debugging to help track down memory issues such as use-after-free or out-of-bounds access. Currently only supported on Windows. * `ansi` - fallback to default system allocator
* fix inconsistencies in filecas due to failing to remove payload file during ↵Dan Engelbrecht2024-11-221-2/+2
| | | | | | | | GC (#224) make sure we rewrite filecas entries if chunk size changes (due to compression changes) hardening of move/write files in filecas if we encounter a filecas entry with mismatching size (due to pre-existing bug) we validate the file and update the index if we find a bad filecas file on disk we now attempt to remove it

* workspace share security (#192)Dan Engelbrecht2024-10-233-1/+33
| | | | | | | - Improvement: Reworked workspace shares to be more secure. Workspaces and workspace shares can only be created using the `zen workspace` command, the http endpoint is disabled unless zenserver is started with the `--workspaces-allow-changes` option enabled. - Each workspace are now configured via a `zenworkspaceconfig.json` file in the root of each workspace - A workspace can allow shares to be created via the http interface if the workspace is created with the `--allow-share-create-from-http` option enabled - A new http endpoint at `/ws` - issuing a `Get` operation will get you a list of workspaces - A new http endpoint at `/ws/refresh` - issuing a `Get` will make zenserver scan for edits in workspaces and workspace shares
