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.
Move `tracy_set_option` and `tracy_set_option_value` from `CMakeLists.txt` into `cmake/options.cmake`. Add `tracy_set_option_value_as_string` for options whose value is embedded as a C string literal. All three accept an optional trailing target argument; when provided, the option is also propagated as a PUBLIC compile definition on that target.
Existing `set_option`/`set_option_value` are unchanged but will be replaced later by the `tracy_*` versions.
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.
If as.ipMaxAsm.local is 0 and m_childCalls is false, GetHotnessColor(count, 0)
performs float(2 * count) / 0. The old code explicitly guarded against this
with the as.ipMaxAsm.local != 0 check.
The "outdated" concept is strictly for chain of assistant replies with
nothing in between, i.e.:
"I will check this..." <- outdated
<tool call> <- not displayed
"Now I will do that..." <- outdated
<tool call> <- not displayed
"Let me consider..." <- outdated
<reasoning> <- not displayed
"Now I have the answer..."
The first three messages are at this point considered outdated, as the
model provided a more recent message.
Note that in chain such as below there are NO outdated messages:
"How can I help..."
<user input>
"Ah, I see..."
<user input>
"You may try to..."
Similarly, if the tool calls or reasoning sections are explicitly enabled
in the chat UI, the messages are also not considered outdated.
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 can happen notably when the user does not call ZoneEnd.
I used 256 arbitrarily as it seemed higher values would just make the UI freeze anyway due to perf reasons.
I added a warning in the notification area so that users can locate it.
Many of the zones would have a negative running time due to a missing `cs->IsEndValid()` check.
This could end reporting context switches before the zone start, due to `cs->End()` returning -1.
This happened when systrace dropped event, or when using Fibers and `TracyFiberEnter` is called on the new thread once the fiber has been scheduled. (The manual actually does not really hint this is wrong, we should probably fix the manual or the server code.)
In both cases, we assume runtime to be 0 for that context switch. Since we have no actual information. Both options (counting full runtime or no runtime) are wrong, and most of the code handling `!cs->IsEndValid()` uses `Start` instead so that's what I did. This is still a net improvement over displaying negative values. If we want to change this handling, we'd need to review the other places that do `it->IsEndValid() ? it->End() : it->Start()` as well.
It also seems two different concepts were being mixed:
1. Do we have any context switch data at all ? (`it != ctx->v.end()` ie `count != 0`)
2. Do we have complete data for the last context switch (`eit != ctx->v.end()`)
This led to some places of the code not displaying or counting running time at all, notably when hovering a zone.
I think most of the time we wanted 1, as it reports correctly and assumes the last context switch is still running, which is a fair assumption if we didn't see one putting the thread to sleep.
I also fixed a case where we were overcounting runtime when range start was during a sleep.
- save_worker binding: wraps Worker::Write under
Worker::ObtainLockForMainThread() so live instances yield their
receive thread cooperatively for the save's duration — the same
pattern View::Save uses in the GUI.
- save_trace MCP tool: defaults to async_mode=True for multi-GB
traces; reuses the existing Task/executor machinery so callers
poll via the task tool. Path resolution mirrors load_capture.
- manual/tracy.tex: add save_trace bullet to the MCP tool list.
