2016-02-25tools lib traceevent: Fix output of %llu for 64 bit values read on 32 bit ↵Steven Rostedt1-3/+2
machines commit 32abc2ede536aae52978d6c0a8944eb1df14f460 upstream. When a long value is read on 32 bit machines for 64 bit output, the parsing needs to change "%lu" into "%llu", as the value is read natively. Unfortunately, if "%llu" is already there, the code will add another "l" to it and fail to parse it properly.

2015-05-06tools lib traceevent kbuffer: Remove extra update to data pointer in PADDINGSteven Rostedt (Red Hat)1-1/+0
commit c5e691928bf166ac03430e957038b60adba3cf6c upstream. When a event PADDING is hit (a deleted event that is still in the ring buffer), translate_data() sets the length of the padding and also updates the data pointer which is passed back to the caller. This is unneeded because the caller also updates the data pointer with the passed back length. translate_data() should not update the pointer, only set the length.

2014-06-01tools lib traceevent: Fix memory leak in pretty_print()Steven Rostedt1-0/+1
commit de04f8657de9d3351a2d5880f1f7080b23b798cf upstream. Commit 12e55569a244 "tools lib traceevent: Use helper trace-seq in print functions like kernel does" added a extra trace_seq helper to process string arguments like the kernel does it. But the difference between the kernel and the userspace library is that the kernel's trace_seq structure has a static allocated buffer. The userspace one has a dynamically allocated one. It requires a trace_seq_destroy(), otherwise it produces a nasty memory leak.

2014-01-23perf tools: Fix traceevent plugin path definitionsJosh Boyer1-1/+1
The plugindir_SQ definition contains $(prefix) which is not needed as the $(libdir) definition already contains prefix in it. This leads to the path including an extra prefix in it, e.g. /usr/usr/lib64. The -DPLUGIN_DIR defintion includes DESTDIR. This is incorrect, as it sets the plugin search path to include the value of DESTDIR. DESTDIR is a mechanism to install in a non-standard location such as a chroot or an RPM build root. In the RPM case, this leads to the search path being incorrect after the resulting RPM is installed (or in some cases an RPM build failure). Remove both of these unnecessary inclusions.

2013-12-18tools lib traceevent: Introduce pevent_filter_strerror()Namhyung Kim3-61/+61
The pevent_filter_strerror() function is for receiving actual error message from pevent_errno value. To do that, add a static buffer to event_filter for saving internal error message If a failed function saved other information in the static buffer returns the information, otherwise returns generic error message.

Those functions stringify filter arguments. As caller of those functions handles NULL string properly, it seems that it's enough to return NULL rather than calling die().

2013-12-13tools lib traceevent: Refactor pevent_filter_match() to get rid of die()Namhyung Kim2-57/+99
The test_filter() function is for testing given filter is matched to a given record. However it doesn't handle error cases properly so add a new argument err to save error info during the test and also pass it to internal test functions. The return value of pevent_filter_match() also converted to pevent_errno to indicate an exact error case.
