* Update perfetto args.gn.in
- remove enable_perfetto_tools_trace_to_text (unused)
* core timeout implementation
- requires OMNITRACE_CI=ON
- requires OMNITRACE_CI_TIMEOUT=<sec>
- adds pthread_self and std::this_thread::get_id to thread info
- pthread_create_gotcha stores native handles (pthread_self)
* Testing updates
- improve detection of segfault/failures with PASS_REGEX exists
- add OMNITRACE_CI_TIMEOUT env variable to all tests
* Line-info in releases
- e.g. -g1 + more options to minimize size of debug info
* Fix typo in config exit action message
* OMNITRACE_UNLIKELY around debug/verbose messages
* format fixes
* Overflow tests + capability check
* transpose example update
- link to threads library
* roctracer/rocprofiler update
- in ROCm 5.5.0, cannot include rocprofiler.h and roctracer.h in same file due to conflicting enum defs
- Moved HSA tracing setup/shutdown to component::roctracer
* roctracer update
- fix definition of roctracer::setup when disabled
* Update fork example
- detach threads on main PID
- flush io outputs when printing info
* Update overflow tests
- pass regular expressions
- overflow on PERF_COUNT_SW_CPU_CLOCK event
* fork gotcha update
- use getpid() instead of getppid()
* update fork example
- wait on threads calling fork
* timeout update
- wait on timeout thread to launch before proceeding
* Address and thread sanitizer fixes
- Fix compilation with clang
- Tweak perfetto copy to build tree
- Added suppression files to scripts
- fix LD_PRELOAD support in omnitrace-causal and omnitrace-sample
- use spin_mutex and spin_lock from timemory instead of atomic_mutex and atomic_lock
- state uses atomic
- fix some memory leaks
- tweak testing
- mpi tests do not use preload
- increase timeout when using sanitizers
- add env LD_PRELOAD when using sanitizers
* Tweak perfetto build
* Update timemory submodule
* Update version to 1.8.1
* Update omnitrace-leak.supp
* Update timemory submodule
- fixed spin_mutex implementation
* Remove previously added addr_space->allowTraps(instr_traps)
- this appears to cause errors during binary rewrite
* causal testing updates
- relaxed causal validation on CI systems (to account for hyperthreading decreasing prediction)
- improved impact calculation
- other general improvements to validate-causal-json.py
* Improve fork handling for perfetto
- numerous updates changing perfetto:: to ::perfetto::
- added perfetto_fwd.hpp
* Updated fork example
- user API for validation that stopping/starting perfetto is valid
* Misc fixes to perfetto + fork support
- tweak regions in fork example
- handle disabling tmp files
- get rid of stop/start with perfetto before/after fork
- fixed sampling support during fork
- tweak env of fork test
* Fix find_package in build-tree
* Fix buildtree export
* Fix buildtree export
* Restructured ConfigInstall before adding examples
* Guard against creating tmp file in sampling when disabled
* Fix buildtree package
* formatting
* exit handlers on child processes
- quick exit to avoid perfetto cleanup
* Further tweaking of causal tests for reliability
- enable PROCESSOR_AFFINITY
- decrease to 5 iterations
* Further tweaking of causal tests for reliability
- disable PROCESSOR_AFFINITY for fast func e2e tests
- enabling affinity results in (valid) speedup predictions greater than zero
* Fixes to fork handling
- use pthread_atfork for redundancy if fork_gotcha fails
* cmake formatting
* Fix fork init settings + install components
- remove dl from PROJECT_BUILD_TARGETS
* Testing tweaks
- fix mpi-binary-rewrite-run regex when OMNITRACE_VERBOSE set > 1 in env
- increase causal e2e iterations to 8
* Fix "Test User API"
- test-find-package.sh included dl component
* Further tweaks to causal validation
- further considerations of variance
* Always print PID in log messages
* omnitrace-dl updates
- omnitrace_preload does not call omnitrace_init or omnitrace_init_tooling
- omnitrace_preload will call omnitrace_set_mpi if OMNITRACE_USE_MPI
or OMNITRACE_USE_MPIP in the env is true but not call it otherwise
because doing so either overrides OMNITRACE_USE_PID (when true) or
disable mpip from initialization (when false) and the MPI
init can be caught later and override OMNITRACE_USE_PID
* config updates
- set_setting_value sets user update type
- remove volatile from get_settings_configured
- don't override settings::default_process_suffix
- don't kill process in omnitrace_exit_action
- set_state ignores updating state if >= State::Finalized
* Handle state > State::Finalized
* fork gotcha updates
- unsets LD_PRELOAD
- sets OMNITRACE_ROOT_PROCESS
- sets OMNITRACE_CHILD_PROCESS
* libomnitrace library.cpp updates
- basic_bundle for fini metrics
- handle finalization from child process
* sampling updates
- sampling::shutdown handles when child process
* Add example and test using fork
* Update run-ci script to support not submitting
* Tweak test envs
* Update build flags when codecov enabled
* remove unnecessary includes of sampling header
* Replace mpi copy/fini static lambda with free-funcs
* Update codecov job
* Fix OMPT segfaults after finalization
* Miscellaneous updates after rebase
* fixes for causal profiling
* revert some run-ci.sh changes
* Disable storing env in sampling::shutdown
* formatting fix
* Update timemory submodule
- fixed occasional synchronization issues with allocator offloading
- exclude protozero:: from internal samples
* improve root/child process detection
- avoid omnitrace_finalize in MPI when child process
- revert some testing tweaks
