The imgui 1.92.9b ini writer omits 'Column N' lines for columns without
saved data (e.g. the unsized, unsorted 'Zone' column of the child zones
table, which only persists the default Time sort). On restore, the
missing entry keeps Index == -1, the sequential fallback in
TableLoadSettingsForColumns() assigns it to the remaining column, and
TableFixDisplayOrder() sorts DisplayOrder -1 to the end - flipping the
column order (Time | Zone in the zone info child list) for the session.
Guard the non-reorderable load path against phantom entries.

The group name-sort key was always the source location name, but
single-member groups display the zone-level name, which prefers the
runtime ZoneName() string. Such groups sorted by a name the user could
not see. The key now mirrors the display: zone name for single-member
groups, source location name for the rest. GPU zones are unaffected
(their names always resolve from the source location).
The child zone list was always sorted by time. It is now a sortable
table with Zone and Time columns, like the statistics view and the
time distribution table in the same window: Time is the default sort
(descending, as before), Zone sorts by name with time as the
tiebreak, and groups plus their members follow the same selection.
The sort choice persists across zones and the group toggle. Group
and child names are looked up once per draw only when name-sorting.
Otherwise on unmap you can get the validation layer error:
"ID3D12Resource3::ID3D12Resource::Unmap: pWrittenRange does not point to an empty D3D12_RANGE and
the heap type is D3D12_HEAP_TYPE_READBACK. Readback resources can be written by the CPU but there's
not much utility. The rationale is that readback heaps are stuck in COPY_DEST state such that the
GPU can never use what the CPU is writing. The range [0, 524288) should be empty (Begin >= End)."

"This indicates the region the CPU might have modified" -> tracy essentially declares the entire range as written, but it's not even a cpu->gpu write buffer -> bug.
TracyConfig.cmake now sets TRACY_VERSION_STRING and a
TracyConfigVersion.cmake is generated and installed, so
find_package(Tracy X.Y CONFIG) works against installed trees.
Compatibility mode is SameMinorVersion: for a 0.x project the minor
version is the compatibility unit, and consumers who need to pin the
exact version can use find_package(... EXACT). SamePatchVersion is
not an option - it requires CMake 4.4 while the project minimum is
3.13.
SysTraceStart previously reported success even when no perf events
could be opened, leaving a worker thread running over no buffers
and an empty CPU section without explanation; it now fails in that
case. Also log when /proc/kallsyms cannot be read, which otherwise
silently results in ??? kernel stack frames.
perf_event_attr.use_clockid only exists since Linux 4.1 and
sample_max_stack since Linux 4.8; older kernels (e.g. the 3.18
kernels of 32-bit Android devices) reject the attributes with
EINVAL/E2BIG, which silently disabled all of system tracing.
Classify the running kernel from uname(2) and only send the fields
its perf_event_open ABI supports.
The symbol worker thread, which answers source code queries, only exists
when call stack support is compiled in. Handle the query directly in the
main thread so it is always answered and the server can terminate.
The mrc to c13/c0/3 (thread id register) is undefined on ARMv5 (e.g.
ARM926EJ-S) and SIGILL'd during init. __builtin_thread_pointer lowers
to the same mrc on targets with a thread pointer register and to
__aeabi_read_tp on soft-TLS targets.
Delayed init was introduced 2019-02-19 in ef5e30056 and was lazy init at
that time, matching the name.
This changed 2020-05-19 in 4eb78f5c8, when auto-init was added, making
delayed init not delayed anymore.
While the option is still needed to make manual lifetime work, and it has
to be enabled on apple, there's no reason anymore to expose it to users.
The macro fast paths only reference GetProfiler from -O0 code, direct
calls, and ON_DEMAND builds: the single GetProfiler() call on the macro
path sits behind the constexpr-dead callstack guard and is folded away
at -O1+, so Release builds carried no config fingerprint and mismatched
clients linked silently.
GetToken is the hot-path binding of every queueing macro and is
referenced at all optimization levels; mangle it the same way so
mismatches fail at link time in Release builds too.
ImGui OpenGL loader uses dlopen / dlsym / dlclose to load the OpenGL
implementation.
Linking with libdl is not needed with glibc >= 2.34 (released in 2021):
NEWS for version 2.34
=====================
Major new features:
* In order to support smoother in-place-upgrades and to simplify
the implementation of the runtime all functionality formerly
implemented in the libraries libpthread, libdl, libutil, libanl has
been integrated into libc. New applications do not need to link with
-lpthread, -ldl, -lutil, -lanl anymore.
(...)
Older glibc versions and also possibly other libc implementations still
need the libdl link.
The gpu backends each used a bare 255 as the sentinel for a
not-yet-initialized context id. Define InvalidGpuContextId (-1) in
TracyQueue.hpp and replace the scattered 255s and their asserts
with it.
Id exhaustion is handled by an error message and an assert in the
new NextGpuContextId() getter. Non-assert builds continue execution,
at which point they are no longer valid. Handling this code path
is out of scope here. Various attempts at handling the exhaustion
problem have been otherwise purged from the API implementations.
Alloc and free events stored the OS thread, so the memory view's
Zone alloc/Zone free columns resolved the zone on the OS thread's
timeline instead of the currently-running fiber. Attribute them to
the active fiber the same way zone and message events are
(follow ThreadData::fiber).
The decoder recovered offset-encoded 16-bit string lengths into a
uint16_t, so sz += ProtocolOffset8Bit truncated lengths in [65536,
65791] back into [0, 255] in release builds, desynchronizing the
stream. Read the wire value into uint16_t sz16 and recover into a
uint32_t sz, relying on automatic promotion for the addition.
Align the client asserts with the encoder's actual capacity
(ProtocolOffset8Bit + uint16 max).
Define CMAKE_PARALLEL once per environment (--parallel 2 on GitHub CI,
unlimited locally) and use it across every cmake build, so all builds
are OOM-protected, not just the profiler GUI.
Set contents: read permissions on every workflow and add per-workflow
concurrency groups keyed on the git ref to deduplicate concurrent runs.
Release workflow keeps cancel-in-progress: false so a release build is
never canceled; job-level contents: write on attach-to-release is
preserved. Concurrency groups use hardcoded prefixes so reusable
workflows called from release.yml do not inherit the caller workflow
name and collide.
Ship the version header alongside the rest of public/common so installed
users can query the Tracy version at compile time; it is the single
source of truth CMake already parses via cmake/version.cmake.
TracyFormat.h is transitively included by installed public headers
(TracyC.h, TracyProfiler.hpp, TracyScoped.hpp) but was missing from
the common_includes install list in both build systems, breaking
installed users. Add it to the list in CMakeLists.txt and meson.build.
