------------------------------------------------------------------- Sat Jul 27 17:57:36 UTC 2024 - Jan Engelhardt <jengelh@inai.de> - Update to release 1.8.1 * Plug some memory leaks - Delete 0001-libtracefs-meson-build-tracefs-mmap-by-default.patch (merged) ------------------------------------------------------------------- Mon Jun 17 14:22:13 UTC 2024 - Daniel Wagner <daniel.wagner@suse.com> - Update to v1.8.0 * remove: add-explicit-meson-thread-dependency.patch * tracefs_follow_event_clear() and tracefs_follow_missed_events_clear() API to clean up followers if the tracefs instance is going to be used for other iterations * tracefs_instance_file_write_number() A simple helper function to make it easier to write numbers into the tracefs files. It does the conversion from number to string, as the files expect strings and not numbers. * Add API to work with kbuffer, which gives more control to the application and speeds it up: tracefs_cpu_read_buf() tracefs_cpu_buffered_read_buf() tracefs_cpu_flush_buf() * tracefs_instance_get_buffer_percent() and tracefs_instance_set_buffer_percent() Modify the buffer_percent file that allows readers to block until the buffer is filled to a given percent. This keeps the reader from causing events that will add noise to the trace. * tracefs_instance_clear() Helper to clear the contents of the current trace instance. * tep_get_sub_buffer_data_size() Helper to retrieve the current sub-buffer data size. The Linux kernel tracing ring buffer is broken up into smaller sub-buffers. This returns the size of the data portion of those sub-buffers (does not include the sub-buffer meta data). * tracefs_load_headers() API to just load the information about the sub-buffers and nothing more. * API to extract tracing ring buffer statistics tracefs_instance_get_stat() tracefs_instance_put_stat() tracefs_buffer_stat_entries() tracefs_buffer_stat_overrun() tracefs_buffer_stat_commit_overrun() tracefs_buffer_stat_bytes() tracefs_buffer_stat_event_timestamp() tracefs_buffer_stat_timestamp() tracefs_buffer_stat_dropped_events * tracefs_instance_set_subbuf_size() and tracefs_instance_get_subbuf_size() API to modify the sub-buffers size of the tracing ring buffer. * Added TIMESTAMP_DELTA and TIMESTAMP_DELTA_USECS to tracefs_sql() as a shortcut for (end.TIMESTAMP - start.TIMESTAMP) and (end.TIMESTAMP_USECS - start.TIMESTAMP_USECS) respectively * Add PID filtering API: tracefs_filter_pid_function() tracefs_filter_pid_events() tracefs_filter_pid_function_clear() tracefs_filter_pid_events_clear() * Added tracefs_cpu_snapshot_open() to read the raw data of snapshot buffers * Added snapshot functions: tracefs_snapshot_snap() tracefs_snapshot_clear() tracefs_snapshot_free() * Added ring buffer memory mapping APIs tracefs_cpu_open_mapped() tracefs_cpu_is_mapped() tracefs_mapped_is_supported() tracefs_cpu_map() tracefs_cpu_unmap() * Updates: - Increase pipe max size to max value when using splice. - Clear "max_graph_depth" on tracefs_instance_reset() - Add missing headers to syscall() and SYS_* defines - Add dependency fixes to meson build - Fix some documentation / man page issues - Fix memory leaks - Fix cscope rule - Fix issues in unit tests - Added many more unit tests ------------------------------------------------------------------- Thu Jun 15 18:50:11 UTC 2023 - Tony Jones <tonyj@suse.com> - Add explicit thread dependency for older versions of meson (i.e SLE-15-SP5) New patch: add-explicit-meson-thread-dependency.patch ------------------------------------------------------------------- Thu Jun 15 18:40:11 UTC 2023 - Tony Jones <tonyj@suse.com> - Update to version 1.7.0 * Add initial support for meson * Add tracefs_kprobe_destroy() to index man page * State that tracefs_dynevent_create() is needed for tracefs_kprobe_alloc() * Add missing prototypes in top level man page * Add tracefs_kprobe_destory() API * Add helper function to destroy dynamic event * Add tracefs_time_conversion() API * Add tracefs_find_cid_pid() API * Fix crashing of synth test when synths exist * Do not use synth for test_synth element * Clarify the tracefs_synth_create() man page * Do not allow tracefs_synth_set_instance() on created synth * Documentation for tracefs_synth_set_instance * New API to set synthetic event instance * Do not segfault in tests if synthetic events are not configured * Add tracefs_instance_tracers() API * Do not use hwlat tracer and fdb_delete event for test * Add stacktrace to tracefs_sql() * Unit test for tracefs_instance_reset() * Documentation for tracefs_instance_reset() * New API to reset ftrace instance - Drop patch 0001-libtracefs-Add-initial-support-for-meson.patch (upstream) ------------------------------------------------------------------- Tue Feb 7 13:23:20 UTC 2023 - Daniel Wagner <daniel.wagner@suse.com> - Sync meson build patch with latest upstream version * Documentation is built via extra build target ------------------------------------------------------------------- Wed Jan 18 09:39:05 UTC 2023 - Dirk Müller <dmueller@suse.com> - update to 1.6.4: * Flush pipe data in tracefs_cpu_flush() * Add check for duplicate functions in man pages * Make sure 32 bit works on 64 bit file systems ------------------------------------------------------------------- Tue Dec 27 09:22:13 UTC 2022 - Daniel Wagner <daniel.wagner@suse.com> - Use meson to build package * add 0001-libtracefs-Add-initial-support-for-meson.patch ------------------------------------------------------------------- Fri Dec 16 15:06:03 UTC 2022 - Jan Engelhardt <jengelh@inai.de> - Update to release 1.6.3 * Fix a regression of where tracefs_tracing_dir() did not mount the tracefs file system if it was not already mounted. Same for mounting debugfs with tracefs_debug_dir(). * Have tracefs_tracing_dir() and tracefs_debug_dir() check if the cached directory still exists and is mounted. ------------------------------------------------------------------- Fri Nov 25 00:14:30 UTC 2022 - Jan Engelhardt <jengelh@inai.de> - Update to release 1.6.1 * Fix tracefs_iterate_raw_events() to handle NULL callback ------------------------------------------------------------------- Wed Nov 16 01:32:28 UTC 2022 - Jan Engelhardt <jengelh@inai.de> - Update to release 1.6.0 * No changelog provided by upstream * A set of new API functions ------------------------------------------------------------------- Mon Aug 29 09:59:28 UTC 2022 - Jan Engelhardt <jengelh@inai.de> - Update to release 1.4.2 * Build fixes only (parallel build, musl support) ------------------------------------------------------------------- Tue Jun 21 11:27:48 UTC 2022 - Jan Engelhardt <jengelh@inai.de> - Force make -j1 during build because of object file corruption. ------------------------------------------------------------------- Tue Jun 7 08:34:18 UTC 2022 - Daniel Wagner <daniel.wagner@suse.com> - Update to latest upstream version (1.4.1) * Raw uprobe API: tracefs_uprobe_alloc(), tracefs_uretprobe_alloc * Return the debugfs mount point from tracefs_debug_dir() * sqlhst: Fix labels being ignored for synthetic event field * sqlhst: Allow same event to be both the start and end event * sqlhst: Use unique names for labels * sqlhst: Report errors when executing commands ------------------------------------------------------------------- Tue Apr 5 15:46:56 UTC 2022 - Daniel Wagner <daniel.wagner@suse.com> - Update to latest upstream version (1.3.1) * Optimized string list handling. It was always stated that some string lists must be freed with tracefs_list_free(), and now it is mandatory, as metadata is used to store the size, and normal freeing of the list will cause memory issues. * More consistency with errno values * sqlhist is now officially built * New methods for setting and reading affinity tracefs_instance_set_affinity_set() tracefs_instance_set_affinity_raw() tracefs_instance_set_affinity() tracefs_instance_get_affinity() tracefs_instance_get_affinity_raw() tracefs_instance_get_affinity_set() * New method to see the system tracers tracefs_instances() * New methods to read and clear the error log tracefs_error_last() tracefs_error_all() tracefs_error_clear() * New methods to modify the string lists tracefs_list_add() tracefs_list_size() * New method to stop the iterator over raw events tracefs_iterate_stop() * New methods to make it easier to access event files tracefs_event_get_file() tracefs_event_file_read() tracefs_event_file_write() tracefs_event_file_append() tracefs_event_file_clear() tracefs_event_file_exists() * New method to get the available filter functions tracefs_filter_functions() * New methods to enable or disable tracers tracefs_tracer_set() tracefs_tracer_clear() * New methods for streaming the trace_pipe file tracefs_trace_pipe_stream() tracefs_trace_pipe_print() tracefs_trace_pipe_stop() * New methods for creating, modifying and destroying dynamic events tracefs_dynevent_create() tracefs_dynevent_destroy() tracefs_dynevent_destroy_all() tracefs_dynevent_free() tracefs_dynevent_list_free() tracefs_dynevent_get_all() tracefs_dynevent_get() tracefs_dynevent_info() tracefs_dynevent_get_event() * New method to create an event probe (then use dynamic methods above) tracefs_eprobe_alloc() * New methods to create kprobes and kretprobes tracefs_kprobe_alloc() tracefs_kretprobe_alloc() tracefs_kprobe_raw() tracefs_kretprobe_raw() * New methods for creating, modifying and destroying histograms tracefs_hist_free() tracefs_hist_alloc() tracefs_hist_alloc_2d() tracefs_hist_alloc_nd() tracefs_hist_get_name() tracefs_hist_get_event() tracefs_hist_get_system() tracefs_hist_add_key() tracefs_hist_add_value() tracefs_hist_add_sort_key() tracefs_hist_set_sort_key() tracefs_hist_sort_key_direction() tracefs_hist_add_name() tracefs_hist_append_filter() tracefs_hist_echo_cmd() tracefs_hist_command() tracefs_hist_start() tracefs_hist_pause() tracefs_hist_continue() tracefs_hist_reset() tracefs_hist_destroy() * New methods for creating, modifying and destroying synthetic events tracefs_synth_get_name() tracefs_synth *tracefs_synth_alloc() tracefs_synth_add_match_field() tracefs_synth_add_compare_field() tracefs_synth_add_start_field() tracefs_synth_add_end_field() tracefs_synth_append_start_filter() tracefs_synth_append_end_filter() tracefs_synth_trace() tracefs_synth_snapshot() tracefs_synth_save() tracefs_synth_complete() tracefs_synth_get_start_hist() tracefs_synth_create() tracefs_synth_destroy() tracefs_synth_free() tracefs_synth_echo_cmd() tracefs_synth_raw_fmt() tracefs_synth_show_event() tracefs_synth_show_start_hist() tracefs_synth_show_end_hist() tracefs_synth_get_event() * New methods to modify event filters tracefs_filter_string_append() tracefs_filter_string_verify() tracefs_event_filter_apply() tracefs_event_filter_clear() tracefs_event_append_filter() tracefs_event_verify_filter() * New method to create a synthetic event via a SQL string tracefs_sql() The man page comes with its own program (sqlhist). ------------------------------------------------------------------- Tue Feb 22 12:34:56 UTC 2022 - olaf@aepfle.de - Force correct pkgconfig_dir location to fix build ------------------------------------------------------------------- Wed Jan 19 13:13:55 UTC 2022 - Dario Faggioli <dfaggioli@suse.com> - Update to latest upstream version (1.2.5) * No changelog provided again ------------------------------------------------------------------- Fri May 14 15:06:28 UTC 2021 - Dario Faggioli <dfaggioli@suse.com> - Update to new upstream version (1.2.0) * No changelog was provided by upstream. * libtracefs: Add tracefs_event_enable/disable() API ------------------------------------------------------------------- Mon May 10 08:03:05 UTC 2021 - Dario Faggioli <dfaggioli@suse.com> - update to new upstream version (1.1.2) - drop patch 294319.patch (already present upstream) ------------------------------------------------------------------- Tue Dec 22 19:28:57 UTC 2020 - Jan Engelhardt <jengelh@inai.de> - Initial package (version 1.0.0) for build.opensuse.org - Add 294319.patch
