2019-09-01libtraceevent: Remove tep_register_trace_clock()Tzvetomir Stoyanov3-14/+0
The tep_register_trace_clock() API is used to instruct the traceevent library how to print the event time stamps. As event print interface if redesigned, this API is not needed any more. The new event print API is flexible and the user can specify how the time stamps are printed.

2019-09-01libtraceevent, perf tools: Changes in tep_print_event_* APIsTzvetomir Stoyanov4-197/+198
Libtraceevent APIs for printing various trace events information are complicated, there are complex extra parameters. To control the way event information is printed, the user should call a set of functions in a specific sequence. These APIs are reimplemented to provide a more simple interface for printing event information. Removed APIs: tep_print_event_task() tep_print_event_time() tep_print_event_data() tep_event_info() tep_is_latency_format() tep_set_latency_format() tep_data_latency_format() tep_set_print_raw() A new API for printing event information is introduced: void tep_print_event(struct tep_handle *tep, struct trace_seq *s, struct tep_record *record, const char *fmt, ...); where "fmt" is a printf-like format string, followed by the event fields to be printed. Supported fields: TEP_PRINT_PID, "%d" - event PID TEP_PRINT_CPU, "%d" - event CPU TEP_PRINT_COMM, "%s" - event command string TEP_PRINT_NAME, "%s" - event name TEP_PRINT_LATENCY, "%s" - event latency TEP_PRINT_TIME, %d - event time stamp. A divisor and precision can be specified as part of this format string: "%precision.divisord". Example: "%3.1000d" - divide the time by 1000 and print the first 3 digits before the dot. Thus, the time stamp "123456000" will be printed as "123.456" TEP_PRINT_INFO, "%s" - event information. TEP_PRINT_INFO_RAW, "%s" - event information, in raw format. Example: tep_print_event(tep, s, record, "%16s-%-5d [%03d] %s %6.1000d %s %s", TEP_PRINT_COMM, TEP_PRINT_PID, TEP_PRINT_CPU, TEP_PRINT_LATENCY, TEP_PRINT_TIME, TEP_PRINT_NAME, TEP_PRINT_INFO); Output: ls-11314 [005] d.h. 185207.366383 function __wake_up Signed-off-by: Tzvetomir Stoyanov <tstoyanov@vmware.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: linux-trace-devel@vger.kernel.org Cc: Patrick McLean <chutzpah@gentoo.org> Link: http://lore.kernel.org/linux-trace-devel/20190801074959.22023-2-tz.stoyanov@gmail.com Link: http://lore.kernel.org/lkml/20190805204355.041132030@goodmis.org Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2019-08-29tools lib traceevent: Remove unneeded qsort and uses memmove insteadSteven Rostedt (VMware)1-6/+49
While reading a trace data file that had 100,000s of tasks, the process took an extremely long time. I profiled it down to add_new_comm(), which was doing a qsort() call on an array that was pretty much already sorted (all but the last element. qsort() isn't very efficient when dealing with mostly sorted arrays, and this definitely showed its issues. When adding a new task to the task list, instead of using qsort(), do another bsearch() with a function that will find the element before where the new task will be inserted in. Then simply shift the rest of the array, and insert the task where it belongs.

2019-08-29tools lib traceevent: Do not free tep->cmdlines in add_new_comm() on failureSteven Rostedt (VMware)1-2/+1
If the re-allocation of tep->cmdlines succeeds, then the previous allocation of tep->cmdlines will be freed. If we later fail in add_new_comm(), we must not free cmdlines, and also should assign tep->cmdlines to the new allocation. Otherwise when freeing tep, the tep->cmdlines will be pointing to garbage.

2019-08-20tools lib traceevent: Fix "robust" test of do_generate_dynamic_list_fileSteven Rostedt (VMware)1-2/+2
The tools/lib/traceevent/Makefile had a test added to it to detect a failure of the "nm" when making the dynamic list file (whatever that is). The problem is that the test sorts the values "U W w" and some versions of sort will place "w" ahead of "W" (even though it has a higher ASCII value, and break the test. Add 'tr "w" "W"' to merge the two and not worry about the ordering.

2019-05-02tools lib traceevent: Change tag string for errorLeo Yan1-1/+1
The traceevent lib is used by the perf tool, and when executing perf test -v 6 it outputs error log on the ARM64 platform: running test 33 '*:*'trace-cmd: No such file or directory [...] trace-cmd: Invalid argument The trace event parsing code originally came from trace-cmd so it keeps the tag string "trace-cmd" for errors, this easily introduces the impression that the perf tool launches trace-cmd command for trace event parsing, but in fact the related parsing is accomplished by the traceevent lib. This patch changes the tag string to "libtraceevent" so that we can avoid confusion and let users to more easily connect the error with traceevent lib.

2019-04-16tools lib traceevent: Fix missing equality check for strcmpRikard Falkeborn1-1/+1
There was a missing comparison with 0 when checking if type is "s64" or "u64". Therefore, the body of the if-statement was entered if "type" was "u64" or not "s64", which made the first strcmp() redundant since if type is "u64", it's not "s64". If type is "s64", the body of the if-statement is not entered but since the remainder of the function consists of if-statements which will not be entered if type is "s64", we will just return "val", which is correct, albeit at the cost of a few more calls to strcmp(), i.e., it will behave just as if the if-statement was entered. If type is neither "s64" or "u64", the body of the if-statement will be entered incorrectly and "val" returned. This means that any type that is checked after "s64" and "u64" is handled the same way as "s64" and "u64", i.e., the limiting of "val" to fit in for example "s8" is never reached. This was introduced in the kernel tree when the sources were copied from trace-cmd in commit f7d82350e597 ("tools/events: Add files to create libtraceevent.a"), and in the trace-cmd repo in 1cdbae6035cei ("Implement typecasting in parser") when the function was introduced, i.e., it has always behaved the wrong way.

2019-04-01tools lib traceevent: Remove call to exit() from tep_filter_add_filter_str()Tzvetomir Stoyanov1-3/+0
This patch removes call to exit() from tep_filter_add_filter_str(). A library function should not force the application to exit. In the current implementation tep_filter_add_filter_str() calls exit() when a special "test_filters" mode is set, used only for debugging purposes. When this mode is set and a filter is added - its string is printed to the console and exit() is called. This patch changes the logic - when in "test_filters" mode, the filter string is still printed, but the exit() is not called. It is up to the application to track when "test_filters" mode is set and to call exit, if needed.
