* improved post upload/download summary (#308)Dan Engelbrecht2025-03-181-8/+10
| | | | | | | | | * added ValidateStatistics and improved post upload summary * improved download statistics * smoother stats update when compressing * better feedback during stream compresss/decompress * don't capture TotalPartWriteCount by reference * disk stats cleanup * multi-test-download overall timer
* fix quoted command lines arguments (#306)Dan Engelbrecht2025-03-122-0/+5
| | | Handling of quotes and quotes with leading backslash for command line parsing - UE-231677
* fixes for log timestamps (#304)Stefan Boberg2025-03-121-0/+4
| | | | | | * add GetTimeSinceProcessStart returning time since process start. implemented using https://github.com/maxliani/GetTimeSinceProcessStart/tree/main * fix fractions when using epoch mode. Previously it would show the fraction from the absolute time stamp and not relative to epoch * used GetTimeSinceProcessStart to offset the epoch so that it represents the process spawn time
* Build command tweaks (#301)Stefan Boberg2025-03-111-0/+23
| | | | | | - Improvement: Don't chunk up .mp4 files as they generally won't benefit from deduplication or partial in-place-updates - Improvement: Emit build name to console output when downloading a build - Improvement: Added some debug logging - Bugfix: Logging setup would previously not function correctly when not logging to file

* split zencore/memory.h -> memoryview.h, memcmp.h (#228)Stefan Boberg2024-11-2512-45/+59
| | | | | | | 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 Boberg2024-11-2515-10/+990
| | | | | | | | | | | | | 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

* workspace share security (#192)Dan Engelbrecht2024-10-232-1/+3
| | | | | | | - 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
