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. Signed-off-by:

Those _threaded() functions are needed to make hist tree handling thread-safe, but AFAICS the only thing it does is forcing it to use the intermediate 'collapsed' tree. This can be acheived by setting sort__need_collapse to 1 in cmd_top() so no need to keep those _threaded() variants. Signed-off-by:

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.

The sort__has_sym variable is set only if a symbol-related sort key was added. Since branch stack and memory sort dimensions are separated, it doesn't need to be checked from common dimension. Signed-off-by:

It's in common sort dimension so it'd be more natural to place it with other common column index. Signed-off-by:

Since they're used only for perf mem, separate out them to a different dimension so that normal user cannot access them by any chance. For global/local weights, I'm not entirely sure to place them into the memory dimension. But it's the only user at this time. Signed-off-by:

When -v option is given, the symbol sort key prints its address also but it wasn't properly aligned since hists__calc_col_len() misses the additional part. Also it missed 2 spaces for 0x prefix when printing. $ perf report --stdio -v -s sym # Samples: 133 of event 'cycles' # Event count (approx.): 50536717 # # Overhead Symbol # ........ .............................. # 12.20% 0xffffffff81384c50 v [k] intel_idle 7.62% 0xffffffff8170976a v [k] ftrace_caller 7.02% 0x2d986d B [.] 0x00000000002d986d Signed-off-by:
