tools lib traceevent: Changed return logic of trace_seq_printf() and trace_seq_vprintf() APIs

2019-01-08T16:28:13+00:00

In order to make libtraceevent into a proper library, its API should be
straightforward.

The trace_seq_printf() and trace_seq_vprintf() APIs have inconsistent
returned values with the other trace_seq_* APIs.

This path changes the return logic of trace_seq_printf() and
trace_seq_vprintf() to return the number of printed characters, as the
other trace_seq_* related APIs.

tools lib traceevent, perf tools: Split trace-seq related APIs in a separate header file

2018-08-30T18:52:20+00:00

In order to make libtraceevent into a proper library, all its APIs
should be defined in corresponding header files.  This patch splits
trace-seq related APIs in a separate header file: trace-seq.h

tools lib traceevent: Get rid of malloc_or_die() in trace_seq_init()

2014-01-15T18:10:32+00:00

Use plain malloc() and check its return value.

tools lib traceevent: Check return value of realloc()

2014-01-15T18:10:28+00:00

If realloc() fails, it'll leak the buffer.  Also increate buffer size
only if the allocation succeeded.

tools lib traceevent: Add state member to struct trace_seq

2014-01-15T18:10:19+00:00

The trace_seq->state is for tracking errors during the use of trace_seq
APIs and getting rid of die() in it.

tools lib traceevent: Add trace_seq_reset()

2013-07-12T16:52:12+00:00

Sometimes it'd be useful if existing trace_seq can be reused.  But
currently it's impossible since there's no API to reset the trace_seq.
Let's add trace_seq_reset() for this case.

events: Update tools/lib/traceevent to work with perf

2012-04-25T11:12:26+00:00

Some of the util functions of libtraceevent.a conflict with perf,
such as die(), warning() and others. Move them into event-util.h
that is not included by the perf tools.

Also, as perf compiles with 'bool' the filter_arg->bool needs to
be renamed to filter_arg->boolean.
