2014-08-08perf tests: Fix exclude_guest|exclude_host checking for attr testsJiri Olsa2-4/+4
We have a one of the event open fallback case in __perf_evsel__open where we zero exclude_guest|exclude_host fields. This means there's no way for attr tests to find out what's the right value for those fields, so we need to check for both 0 and 1. Luckily we still have other event parsing tests for those fields.

2014-08-08perf tools: Add automated make test suiteJiri Olsa1-0/+138
Adding automated test for testing the build process. To run it you need to be in perf directory or specify one with PERF variable. It's also possible to specify optional Makefile to test via MK variable. Whole suite is executed twice, the second time with O=/tmp/xxx option added. To run the whole suite: $ make -f tests/make - make_pure: cd . && make -f Makefile test: test -x ./perf - make_clean_all: cd . && make -f Makefile clean all test: test -x ./perf - make_python_perf_so: cd . && make -f Makefile python/perf.so test: test -f ./python/perf.so - make_debug: cd . && make -f Makefile DEBUG=1 test: test -x ./perf - make_no_libperl: cd . && make -f Makefile NO_LIBPERL=1 test: test -x ./perf You see command line for 'make_pure' test right away, and the output is stored into 'make_pure' file. To run simple test: $ make -f tests/make make_debug - make_debug: cd . && make -f Makefile DEBUG=1 test: test -x ./perf At this moment tests checks for successfull build and for existence of several built files. Additional after-build checks could be added.

2014-08-08perf record: handle death by SIGTERMDavid Ahern1-1/+1
Perf data files cannot be processed until the header is updated which is done via an on_exit handler. If perf is killed due to a SIGTERM it does not run the on_exit hooks leaving the perf.data file in a random state which perf-report will happily spin on trying to read. As noted by Mike an easy reproducer is: perf record -a -g & sleep 1; killall perf Fix by catching SIGTERM like it does SIGINT. Also need to remove the kill which was added via commit f7b7c26e.
