2011-03-14perf script: Move printing of 'common' data from print_event and renameDavid Ahern1-7/+31
This change does impact output: latency data is trace specific and is now printed after the common data - comm, tid, cpu, time and event name.

2011-01-22perf tools: Fix 64 bit integer format stringsArnaldo Carvalho de Melo1-3/+3
Using %L[uxd] has issues in some architectures, like on ppc64. Fix it by making our 64 bit integers typedefs of stdint.h types and using PRI[ux]64 like, for instance, git does. Reported by Denis Kirjanov that provided a patch for one case, I went and changed all cases.

That already does what was being done here. The warning is now unconditionally given by __perf_session__process_pipe_events, just like for non pipe processing.

2010-12-25perf script: Fix event ordering settings to work with older kernelsArnaldo Carvalho de Melo1-0/+1
If we don't use .ordering_requires_timestamps we'll end up trying to order events with no timestamps when running on older kernels. Problem introduced in eac23d1c. After the last three fixes, perf scripting is back working, tested with new perf userspace on old and new (with sample_id_all) kernels.

2010-12-21perf session: Fallback to unordered processing if no sample_id_allIan Munsie1-1/+1
If we are running the new perf on an old kernel without support for sample_id_all, we should fall back to the old unordered processing of events. If we didn't than we would *always* process events without timestamps out of order, whether or not we hit a reordering race. In other words, instead of there being a chance of not attributing samples correctly, we would guarantee that samples would not be attributed. While processing all events without timestamps before events with timestamps may seem like an intuitive solution, it falls down as PERF_RECORD_EXIT events would also be processed before any samples. Even with a workaround for that case, samples before/after an exec would not be attributed correctly. This patch allows commands to indicate whether they need to fall back to unordered processing, so that commands that do not care about timestamps on every event will not be affected. If we do fallback, this will print out a warning if report -D was invoked. This patch adds the test in perf_session__new so that we only need to test once per session. Commands that do not use an event_ops (such as record and top) can simply pass NULL in it's place.

2010-12-06perf script: Fix compiler warning in builtin_script.c:is_top_script()Stephane Eranian1-5/+5
Fix annoying compiler warning in the is_top_script() function. The issue was that a const char * was cast into a char * to call ends_with(). We fix the users of ends_with() instead. Some are passing a char *, but it is okay to cast the return value of ends_with() to char * (because we understand what ends_with() does). Cc: David S.

2010-12-04perf session: Parse sample earlierArnaldo Carvalho de Melo1-22/+12
At perf_session__process_event, so that we reduce the number of lines in eache tool sample processing routine that now receives a sample_data pointer already parsed. This will also be useful in the next patch, where we'll allow sample the identity fields in MMAP, FORK, EXIT, etc, when it will be possible to see (cpu, timestamp) just after before every event. Also validate callchains in perf_session__process_event, i.e. as early as possible, and keep a counter of the number of events discarded due to invalid callchains, warning the user about it if it happens. There is an assumption that was kept that all events have the same sample_type, that will be dealt with in the future, when this preexisting limitation will be removed.
