Binary instrumentation: more robust exclusion of functions used internally (#238)
## Overview
This PR attempts to increase the stability of binary rewrite and runtime instrumentation.
### Improved protection against self-instrumentation
Using ~~the binary analysis capabilities added from #229~~ the Dyninst SymtabAPI, OmniTrace now does a much better job of avoiding instrumentation of functions which are internally called by OmniTrace:
- The `omnitrace` executable searches for and parses the symbols of various libraries which are known to cause problems when instrumented
- GNU libraries which are common to nearly every library, e.g., `"libc.so.6"`, `"libdl.so.2"`, etc., and thus are outside the scope of the users optimizations efforts
- Libraries which OmniTrace depends on for functionality, e.g. `"libunwind.so"`, `"libgotcha.so"`, `"libroctracer64.so"`, etc.
- OmniTrace skips instrumenting any `module_function` instance when it's member `module_name` or `function_name` variable matches the library name, source file, or function name found for that symbol (unless the user explicitly requests that it be eligible for instrumentation)
- Note: the parsing of the "internal" libraries may result in longer instrumentation time and higher memory usage. Please file an issue if either of these is found to be excessive.
### Function filters based on linkage and visibility
Added options to restrict instrumentation to certain linkage types (e.g. avoid instrumenting weak symbols) and visibility types (e.g. avoid instrumenting hidden symbols).
### Function filters based on instructions
In the past, after instrumentation, some applications instrumented by Dyninst would fail with a trap signal (e.g. #147). In several cases, it was found that this occurred whenever certain instructions were present in the function so an option was added to exclude functions based on one or more regex patterns was added.
## Details
- generates list of "internal" libraries and attempts to find the first match via:
- the library is already open, e.g. `dlopen(<libname>, RTLD_LAZY | RTLD_NOLOAD)`
- searching for the library in `LD_LIBRARY_PATH`
- searching for the library in `OMNITRACE_ROCM_PATH`, `ROCM_PATH`
- searching the folders from `/sbin/ldconfig -p`
- searching for the library in common places such as `/usr/local/lib`
- provides new `--linkage` command line option to restrict instrumentation to functions with particular type(s) of linkage
- Linkage types: `unknown`, `global`, `local`, `weak`, `unique`
- provides new `--visibility` command line option to restrict instrumentation to functions with particular type(s) of visibility
- Visibility types: `unknown`, `default`, `hidden`, `protected`, `internal`
- provides new `--internal-module-include` and `--internal-function-include` command line regex options to bypass automatic exclusion from instrumentation
- provides new `--internal-library-append` command line option to specify a library should be considered internal
- provides new `--internal-library-remove` command line option to specify a library should not be considered internal
- provides new `--instruction-exclude` command line regex option to exclude functions which contain matching instructions
- provides new `--internal-library-deps` command line option to treat libraries linked to internal libraries as internal libraries
- generally, this will only be helpful during runtime instrumentation when OmniTrace is built with an external dyninst library which is dynamically linked to boost libraries and the application is using the same boost libraries
- relaxed restrictions in `module_function::is_module_constrained()`
- relaxed restrictions in `module_function::is_routine_constrained()`
- added a few miscellaneous nullptr checks
## Miscellaneous
- Fix `LD_PRELOAD` + `OMNITRACE_DL_VERBOSE=3` issue
- Adds a sampling offload verbose message
- Improves MPI send-recv.cpp example error message
- Minor tweaks to binary library
- `binary::get_linked_path` returns `std::optional<string>`
- renamed `binary::symbol::read_bfd` to `binary::symbol::read_bfd_line_info`
- `binary::get_binary_info` has param options for reading line info and included undefined symbols
- fixed another edge case instance of resource deadlock during first call to configure_settings
- improved the error log printing in `omnitrace` (does not print repeated messages)

* internal libs append/remove
- options to change which libs are considered internal libraries

- include memory usage info
- option to read libraries linked against internal libs: --internal-library-deps

Global trace delay and duration (#235)
- The primary feature of this PR is the **addition of support for scoping the collection of tracing/profiling data into one or more time-based windows** - Closes #222 - Closes #207 - Support for a real-clock time delay and/or a duration for tracing/profiling was added, *resembling the support for this feature during sampling and process-sampling* - However, above paradigm was enhanced for tracing - Instead of one delay and/or one duration based on real time, ***tracing supports periodic and varying delays and durations and these delay+duration sets can be controlled with different clocks*** - At some point, this capability will be extended to sampling and process-sampling - A secondary feature of this PR are the improvements to the handling of categories (by-product of the primary feature) - For example, previously setting `OMNITRACE_ENABLE_CATEGORIES` to a specific set of categories only eliminated the disabled categories from the perfetto trace, now these are applied to timemory profiles too - A new configuration variable `OMNITRACE_DISABLE_CATEGORIES` was added for when disabling only a handful of categories is easier - There are quite a few miscellaneous modifications which pollute this PR a bit ## Multiple Tracing Windows As noted above, tracing now supports specifying multiple delays and durations _and_ with different clocks. Consider the configuration below with two entries in the format `<DELAY>:<DURATION>:<REPEAT>:<CLOCK_TYPE>`: ```console OMNITRACE_TRACE_PERIODS = 0.5:1.0:2:realtime 10.0:5.0:3:cputime ``` The above configuration defines: 1. `0.5:1.0:2:realtime` - A delay of 0.5 seconds (real-time) - Followed by a data collection duration of 1 second (real-time) - This delay + duration is repeated 2x - Summary: tracing data is collected for 2 out of the first 3 seconds of the application's execution 2. `10.0:5.0:3:cputime` - A delay of 10 seconds (process _CPU-time_) - Followed by a data collection duration of 5 seconds (process _CPU-time_) - This delay + duration is repeated 3x - Summary: tracing data is collected for a total of 15 seconds of process CPU-time in the ensuing 75 seconds of CPU-time during the application execution. - Note: the elapsed CPU-time is the aggregate of the CPU-time consumed by all the threads in the process and should be scaled accordingly, e.g., 4 threads running constantly for 1 second of real-time is ~4 seconds of CPU time. ## `omnitrace-sample` Changes Formerly, `--wait` and `--duration` command-line options only applied to sampling delay and duration. The value of these options are now applied to the tracing delay and duration. To retain the ability to control sampling delay/duration without setting tracing delay/duration or vice versa, `--sampling-wait`, `--sampling-duration`, `--trace-wait`, and `--trace-duration` options were added. `omnitrace-sample` also has new options for most of the new configuration options detailed below. ## New configuration options | Option | Description | | ------- | ----------- | | `OMNITRACE_DISABLE_CATEGORIES` | inverse behavior from `OMNITRACE_ENABLE_CATEGORIES` -- populates list of all available categories and then removes the specified ones. | | `OMNITRACE_TRACE_DELAY` | Single floating-point number specifying time to wait before starting data collection. Analagous to `OMNITRACE_SAMPLING_DELAY` and `OMNITRACE_PROCESS_SAMPLING_DELAY` | | `OMNITRACE_TRACE_DURATION` | Single floating-point number specifying data collection duration. Analagous to `OMNITRACE_SAMPLING_DURATION` and `OMNITRACE_PROCESS_SAMPLING_DURATION` | | `OMNITRACE_TRACE_PERIOD_CLOCK_ID` | Sets the default clock-type for tracing delay/duration. Always applied to above two options, can be overridden in below option. Accepts `CLOCK_REALTIME`, `CLOCK_MONOTONIC`, `CLOCK_PROCESS_CPUTIME_ID`, `CLOCK_MONOTONIC_RAW`, `CLOCK_REALTIME_COARSE`, `CLOCK_MONOTONIC_COARSE`, `CLOCK_BOOTTIME`. See `man 2 clock_gettime` for details on differences. | | `OMNITRACE_TRACE_PERIODS` | More powerful version for specifying delay + duration. Supports formats: `<DELAY>`, `<DELAY>:<DURATION>`, `<DELAY>:<DURATION>:<REPEAT>`, and `<DELAY>:<DURATION>:<REPEAT>:<CLOCK_ID>`. | ## Miscellaneous Changes - Expanded `critical_trace_categories_t` to include tracing data from MPI, pthread, HIP, HSA, RCCL, NUMA, and Python. - Added categories `thread_wall_time` and `thread_cpu_time` (derived from sampling) - Read DWARF info for breakpoints - Relocated some source code - Reason: necessary to make `libomnitrace` a bit more modular. Eventually, a large chunk will be separated into `libomnitrace-core`, `libomnitrace-binary`, etc. in order to facilitate re-usability - Relocated some functionality from `runtime.cpp` to `config.cpp` - Relocated code using rocm-smi library to query number of devices to `gpu.cpp` (where the code for using HIP to query number of devices is) - Relocated code for perfetto config and perfetto session out of tracing namespace to reside with other perfetto code - `OMNITRACE_COLORIZED_LOG` configuration option renamed to `OMNITRACE_MONOCHROME` - Backwards compatibility via a deprecated option was not retained here since the logic changed (i.e. true in former means false in latter) - Replaced `TIMEMORY_DEFAULT_OBJECT` macro with `OMNITRACE_DEFAULT_OBJECT` macro - Updated some code in roctracer to use `component::category_region` instead of explicitly using `tracing::` functions - Updated `backtrace_metrics` to better support controlling their presence in the traces/profiles via categories - Added support for `--print` in `validate-timemory-json.py` - Generic `OMNITRACE_ADD_VALIDATION_TEST` CMake function ## Git Log * OMNITRACE_DEFAULT_OBJECT - replace TIMEMORY_DEFAULT_OBJECT with TIMEMORY_DEFAULT_OBJECT * trace-time-window example + tests - adds cmake OMNITRACE_ADD_VALIDATION_TEST function for testing - validate-timemory-json.py now supports printing (-p) - update to OMNITRACE_STRIP_TARGET * Update timemory submodule - detailed backtrace print /proc/<PID>/maps - operation::push_node verbosity change - storage::insert_hierarchy use emplace + at instead of operator[] -

{get,set}_signal_handler - removes config.cpp link dependency for omnitrace_finalize - get_realtime_signal() + get_cputime_signal() + get_sampling_signals() - moved from runtime.cpp to config.cpp * utility::convert - helper function for converting string to a type * pthread_create_gotcha + thread_info updates - thread_index_data::as_string() - tweak printing info about new thread / exited thread * binary updates - get_binary_info has arg to disable dwarf parsing - binary_info contains vector of breakpoint addresses - binary_info:filename() function - binary::get_linked_path - binary::get_link_map has args for dlopen mode - symbol::read_dwarf -> symbol::read_dwarf_entries - symbol::read_dwarf_breakpoints * library updates + categories impl - implement config::set_signal_handler - categories.cpp for handling trace delays -

category stack counters (i.e. push vs. pop counter) for profiling and tracing - push_timemory and pop_timemory accept string_view instead of const char* - tweaked the pop_timemory hash search - {push,pop}_perfetto theoretically supports same invocations as for {push,pop}_perfetto_ts and {push,pop}_perfetto_track - mark_perfetto, mark_perfetto_ts, mark_perfetto_track * category_region update - expanded the critical trace categories - use category_push_disabled - use category_pop_disabled - use category_mark_disabled * constraint implementation - This provides generic functionality for constraining data collection within a windows of time. - E.g., delay, delay + duration, (delay + duration) * nrepeat * COLORIZED_LOG -> MONOCHROME * constraint + omnitrace-causal + omnitrace-sample updates - support for using different clock IDs for constraints - OMNITRACE_TRACE_PERIOD_CLOCK_ID option - tweak to trace-time-window example - tweak to trace-time-window tests * Fix formatting * Update time-window tests - Fix detection of validation support for perfetto - Using the --caller-include feature + runtime instrumentation on Ubuntu 18.04 and OpenSUSE 15.2 results in a segfault in the internals of Dyninst. - For now, mark that these tests will fail - Later, determine if updating Dyninst submodule fixes this problem * Fix OMNITRACE_OUTPUT_PATH for all tests - Provide absolute path instead of relative * Tweak lambda for checking whether HW counters are enabled - causing strange build errors on older GCC compilers * Update dyninst submodule - fix issues with using --caller-include for Ubuntu 18.04, OpenSUSE 15.x * cmake formatting * fix sampling compiler issue for GCC 8 * Tweak thread create message * Increase causal validation iterations |

omnitrace-sample (#169)
- `omnitrace-sample` executable which executes sampling (no instrumentation) - fixes bug with OMPT ignoring value of `OMNITRACE_USE_OMPT` - fixes some issues with sampling duration - new `OMNITRACE_SAMPLING_INCLUDE_INLINES` configuration variable - restricts process-sampling to 100 interrupts/sec when inheriting value from `OMNITRACE_SAMPLING_FREQ` - `OMNITRACE_PROCESS_SAMPLING_FREQ` still supports up to 1000 interrupts/sec - fixes bug with colorized log not truly being disabled in all instances - adds tests for `omnitrace-sample` - adds tests for sampling duration - settings ROCP_TOOL_LIB to libomnitrace-dl throws error - rocprofiler does not configure correctly when this is done - Quiet numa_gotcha warnings - Fixed some shadowed variables |

Crusher hackathon updates (#164)
- improved error handling in dyninst - improved error handling in omnitrace exe - new logging facility for omnitrace exe - improved backtraces - disable concurrent kernels in rocprofiler - updates `setup-env.sh` and modulefile - set `omnitrace_ROOT` - set `HSA_TOOLS_LIB` if roctracer or rocprofiler enabled - set `ROCP_TOOL_LIB` if rocprofiler enabled - closes #163 - No longer make setting `HSA_ENABLE_INTERRUPT=0` the default - this has performance implications - this was set to workaround a bug in ROCR which caused an ioctl call in ROCm to hang when interrupted. But it was only interrupted when realtime sampling was enabled since the CPU-clock doesn't increment when waiting - This bug should be fixed in ROCm 5.3 - omnitrace no longer activates a realtime sampler by default when sampling, thus this bug is no longer encountered unless the user explicitly triggers realtime sampling |

Rework sampling and colorized logs (#140)
## Overview
This is a significant PR which has 3 very notable characteristics:
1. Omnitrace colorizes most of it's logging
2. Completely reworked the sampling
- Samples now record the current instruction pointers instead of strings
- This _dramatically_ decreases the overhead of taking a sample
- The collection of metrics during a sample are split out into another component, enabling that data collection to be disabled -- which decreases the sampling overhead even further
- When both `OMNITRACE_SAMPLING_CPUTIME` and `OMNITRACE_SAMPLING_REALTIME` are ON:
- `OMNITRACE_SAMPLING_CPUTIME_FREQ` and `OMNITRACE_SAMPLING_REALTIME_FREQ` can be used to individually control the sampling frequency
- `OMNITRACE_SAMPLING_CPUTIME_DELAY` and `OMNITRACE_SAMPLING_REALTIME_DELAY` can be used to individually control the delay time before starting
- Now, omnitrace does not start a real-time sampler on the main thread unless `OMNITRACE_SAMPLING_REALTIME` is ON
- In the future, an `OMNITRACE_SAMPLING_TIDS` (and real-time, cpu-time variants) configuration variable(s) will allow you to select which threads will be sampled
3. Files produced by `omnitrace` exe -- `available-instr.txt`, `instrumented-instr.txt`, etc. -- now no longer has `-instr` suffix and are placed in `instrumentation/` subfolder, i.e. `available-instr.txt` -> instrumentation/available.txt`
- This helped de-clutter the output folder
Most of the other edits were reorganization (e.g. internal namespace changes), cleanup, and splitting up functionality.
## Bug Fixes
There is a bug fix with respect to the HSA callbacks which disabled sampling on child threads when an HSA API call was made
## Details
- created thread_info struct for mapping different thread IDs
- reorganized file structure significantly
- added categories.hpp, concepts.hpp
- moved around name trait definitions
- moved all omnitrace components into `omnitrace::component` namespace
- there was a lot of inconsistency b/t using `tim::component` in some places and `omnitrace::component`
- added macros like OMNITRACE_DECLARE_COMPONENT in lieu of TIMEMORY_DECLARE_COMPONENT
- OMNITRACE_CRITICAL_TRACE_NUM_THREADS -> OMNITRACE_THREAD_POOL_SIZE
- roctracer and critical_trace use same thread pool
- critical_trace functions do not lock anymore bc of thread-local TaskGroup
- added `component::local_category_region` to support using `component::category_region` without explicitly passing in name
- removed `component::omnitrace` (unused)
- migrated KokkosP and OMPT to use `component::local_category_region`
- removed `component::user_region` as a result
- migrated omnitrace_{push,pop}_{trace,region}_hidden to use component::category_region
- removed `component::functors` as a result
- migrated some ppdefs
- `api::omnitrace` -> `project::omnitrace`
- `api::(...)` -> `category::(...)`
- improved recording the execution time of threads
- migrated this functionality out of pthread_create_gotcha and into thread_info
- moved mpi_gotcha, fork_gotcha, exit_gotcha, rcclp into omnitrace::component namespace
- split backtrace up into backtrace, backtrace_metrics, backtrace_timestamp components
- sampling.cpp handles setup and post-processing that was formerly in backtrace
- updated logging to use colors
- `OMNITRACE_COLORIZED_LOG` config variable
- updated docs on JSON output from timemory
- instrumentation info in instrumentation subfolder
- added testing for KokkosP entries
- added testing for ompt entries
- add_critical_trace function defined in critical_trace.hpp
- disable push_thread_state and pop_thread_state when thread state is Disabled or Completed
- add comp::page_rss to main bundle
- thread_data supports std::optional instead of std::unique_ptr
- thread_data supports tim::identity<T> to avoid unique_ptr or optional
- tracing::record_thread_start_time()
- tracing::push_timemory and tracing::pop_timemory are templated on CategoryT
- removed anonymous namespace from omnitrace::utility
- sampling backtrace stores instruction pointers instead of strings
- component::category_region updates
- handle disabled thread state
- handle finalized state
- fewer debug messages
- invoke thread_init()
- invoke thread_init_sampling()
- handle push/pop count based on category
- push/pop count only modified when used
- component::cpu_freq
- components/ensure_storage.hpp
- reworked the pthread_create replacement function
- updated parallel-overhead example to report # of times locked
- OMNITRACE_MAX_UNWIND_DEPTH build option
- update timemory submodule
