To help understand the failure. [acme@zoo linux]$ perf test -v 30 30: Test thread mg sharing : --- start --- test child forked, pid 12275 FAILED tests/thread-mg-share.c:68 wrong refcnt (4 != 3) test child finished with -1 ---- end ---- Test thread mg sharing: FAILED! [acme@zoo linux]$ This is under investigation, the thread__delete() calls were replaced with thread__put(), and those cause mismatches because now we need to be more judicious with the thread lifetime management. I.e. previously the thread__delete() would drop the map_group refcount, but now since thread__put doesn't call thread__delete() necessarily. because we have other refcount holders, the map_group refcount will not be as we expected when this test was implemented. Will be fixed soon...

Provides united way of parsing kernel module path into several components. The new kmod_path__parse function and few defines: int __kmod_path__parse(struct kmod_path *m, const char *path, bool alloc_name, bool alloc_ext); #define kmod_path__parse(__m, __p) __kmod_path__parse(__m, __p, false, false) #define kmod_path__parse_name(__m, __p) __kmod_path__parse(__m, __p, true , false) #define kmod_path__parse_ext(__m, __p) __kmod_path__parse(__m, __p, false, true) parse kernel module @path and updates @m argument like: @comp - true if @path contains supported compression suffix, false otherwise @kmod - true if @path contains '.ko' suffix in right position, false otherwise @name - if (@alloc_name && @kmod) is true, it contains strdup-ed base name of the kernel module without suffixes, otherwise strudup-ed base name of @path @ext - if (@alloc_ext && @comp) is true, it contains strdup-ed string the compression suffix It returns 0 if there's no strdup error, -ENOMEM otherwise.

The extensible file description array that grew in the perf_evlist class can be useful for other tools, as it is not something that only evlists need, so move it to tools/lib/api/fd to ease sharing it. v2: Don't use {} like in: libapi_dirs: $(QUIET_MKDIR)mkdir -p $(OUTPUT){fs,fd}/ in Makefiles, as it will not work in some systems, as in ubuntu13.10. v3: Add fd/*.[ch] to LIBAPIKFS_SOURCES (Fix from Jiri Olsa) v4: Leave the fcntl(fd, O_NONBLOCK) in the evlist layer, remains to be checked if it is really needed there, but has no place in the fdarray class (Fix from Jiri Olsa) v5: Remove evlist details from fdarray grow/filter tests.

Adding automated test for breakpoint event signal handler checking if it's executed properly. The test is related to the proper handling of the RF EFLAGS bit on x86_64, but it's generic for all archs. First we check the signal handler is properly called and that the following debug exception return to user space wouldn't trigger recursive breakpoint. This is related to x86_64 RF EFLAGS bit being managed in a wrong way. Second we check that we can set breakpoint in signal handler, which is not possible on x86_64 if the signal handler is executed with RF EFLAG set.

Test can currently return one of 3 states: ok, fail, skip. The ok and fail states are self-explanatory. The skip state means that some of the conditions for running the test was not met, making it impossible to even run the test. For instance, if the hardware doesn't support the 'precise' level required by a test, it will be skipped.

It just will add the O= builddir to PYTHONPATH and try to 'use perf', which will, in verbose mode show the python backtrace with the missing symbols, such as in the problem fixed in the patch after this one: # perf test -v 15 15: Try 'use perf' in python, checking link problems : --- start --- Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: /home/acme/git/build/perf//python/perf.so: undefined symbol: test_attr__enabled ---- end ---- Try 'use perf' in python, checking link problems: FAILED! # Loooong overdue, done.

As they are used from diff and event group report, add a test case to verify their behaviors. In this test I made a fake machine and two evsel. Each evsel got 10 samples (so hist entries) - 5 are common and the rests are not. So after hists__match() both of them will have 5 entries with pair set. And the second evsel has a collapsed entry so that the total number is 9 - I made it in order to simulate more realistic case. Thus after hists__link the first entry will have 14 entries - 5 are common (w/ pair), 5 are unmatch (w/o pair) and 4 are dummy (w/ pair). And the second entry will have 9 entries all have its pair.
