* 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
