Extension point so private/unsupported platforms can plug in their own implementations of the kernel/libc primitives Tracy depends on, without patching the `#if`/`#elif` chains.
Projects supply a platform header via `-DTRACY_PLATFORM_HEADER="\"my_platform.h\""` at build time. Tracy includes it in any TU that needs the hooks. The header toggles per-category `TRACY_HAS_CUSTOM_*` macros and declares matching `tracy::Platform*` functions.
Available hooks:
- `TRACY_HAS_CUSTOM_THREAD_ID` → `PlatformGetThreadId`
- `TRACY_HAS_CUSTOM_USER_INFO` → `PlatformGetHostname`, `PlatformGetUserLogin`, `PlatformGetUserFullName`
- `TRACY_HAS_CUSTOM_SAFE_COPY` → `PlatformSafeMemcpy`
- `TRACY_HAS_CUSTOM_ALLOCATOR` → `PlatformMalloc`, `PlatformFree`, `PlatformRealloc`, `PlatformAllocatorInit`, `PlatformAllocatorThreadInit`, `PlatformAllocatorFinalize`, `PlatformAllocatorThreadFinalize`
Each hook is wired as the first arm of its respective `#if`/`#elif` chain, so existing supported platforms are unaffected.
Template files in `examples/CustomPlatform/` and a new subsection in `manual/tracy.tex` document the mechanism.
The function is about to dispatch between rpmalloc and a pluggable allocator hook, so the rpmalloc-specific name no longer fits. Pure rename plus a small consequence: the SymbolWorker call site no longer needs the TRACY_USE_RPMALLOC guard, since the no-op static-inline fallback in TracyAlloc.hpp makes InitAllocator() safe to call unconditionally.
Replace `#ifdef BSD` (which requires including `<sys/param.h>` first) with explicit checks for `__FreeBSD__`, `__NetBSD__`, `__OpenBSD__` and `__DragonFly__`, matching how these BSDs are already enumerated elsewhere in the codebase (OS name strings, thread id helpers, etc.).
This also avoids leaking the `sys/param.h` requirement through public headers (`TracySysTime.hpp`, `TracyCallstack.h`), where consumers would otherwise need it to correctly see `TRACY_HAS_SYSTIME` / `TRACY_HAS_CALLSTACK`.
`libbacktrace/config.h` is left as-is — it's third-party and only included from .c files where the `BSD` macro can still be picked up locally.
Note: for `setsockopt( m_sock, IPPROTO_IPV6, IPV6_V6ONLY, (const char*)&val, sizeof( val ) );` I added `__APPLE__` too since this was the only place where it was not checked explicitely.
This also replaces `___tracy_emit_message*` by `___tracy_emit_logString`.
The `TracyCMessage*` defines no long include the `;`, which may be a breaking change even though we did already require semi-colon since 0.9.0. See #493 and #592
There are two changes to the protocol:
- `QueueMessageLiteral*` were changed and what used to be addresses are now addresses+metadata
- Other messages now send `QueueMessage*Metadata` with added metadata.
This will later be used to store and transmit message sources, level, etc.
This provides some instructions and tips for the manual. Also:
* Made the calibration feature a CMake option
* Cleaned up some minor code issues
* Fixed an issue with the calibration
* Incremented patch number
