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. Reported-by:

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. Signed-off-by:

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 f7d82350 ("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. Detected by cppcheck. Signed-off-by:

tools lib traceevent: Rename input arguments and local variables of libtraceevent from pevent to tep "pevent" to "tep" renaming of: - all "pevent" input arguments of libtraceevent internal functions. - all local "pevent" variables of libtraceevent. This makes the implementation consistent with the chosen naming convention, tep (trace event parser), and will avoid any confusion with the old pevent name Signed-off-by:

Rename some traceevent APIs for consistency: tep_pid_is_registered() to tep_is_pid_registered() tep_file_bigendian() to tep_is_file_bigendian() to make the names and return values consistent with other tep_is_... APIs tep_data_lat_fmt() to tep_data_latency_format() to make the name more descriptive tep_host_bigendian() to tep_is_bigendian() tep_set_host_bigendian() to tep_set_local_bigendian() tep_is_host_bigendian() to tep_is_local_bigendian() "host" can be confused with VMs, and "local" is about the local machine. All tep_is_..._bigendian(struct tep_handle *tep) APIs return the saved data in the tep handle, while tep_is_bigendian() returns the running machine's endianness. All tep_is_... functions are modified to return bool value, instead of int. Signed-off-by:

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. Signed-off-by:

As struct tep_handler definition is not exposed as part of libtraceevent API, its fields cannot be accessed directly by the library users. This patch implements new APIs, which can be used to access the struct tep_handler fields: tep_get_event() - retrieves an event pointer at a specific index tep_get_first_event() - is modified to use tep_get_event() tep_clear_flag() - clears a tep handle flag tep_test_flag() - test if a given flag is set tep_get_header_timestamp_size() - returns the size of the timestamp stored in the header. tep_get_cpus() - returns the number of CPUs tep_is_old_format() - returns true if data was created by an older kernel with the old data format tep_set_print_raw() - have the output print in the raw format tep_set_test_filters() - debugging utility for testing tep filters Signed-off-by: -
