tools lib traceevent: Remove tep_data_event_from_type() API

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

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

After discussion with Steven Rostedt, we decided to remove the
tep_data_event_from_type() API and to replace it with tep_find_event(),
as it does the same.

tools lib traceevent: Rename tep_is_file_bigendian() to tep_file_bigendian()

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

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

After a discussion with Steven Rostedt, we decided to rename a few APIs,
to have more intuitive names.

This patch renames tep_is_file_bigendian() to tep_file_bigendian().

tools lib traceevent: Changed return logic of tep_register_event_handler() API

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

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

The tep_register_event_handler() functions returns -1 in case it
successfully registers the new event handler. Such return code is used
by the other library APIs in case of an error.

To unify the return logic of tep_register_event_handler() with the other
APIs, this patch introduces enum tep_reg_handler, which is used by this
function as return value, to handle all possible successful return
cases.

tools lib traceevent: Rename struct cmdline to struct tep_cmdline

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

In order to make libtraceevent a proper library, variables, data
structures and functions should have a unique prefix to prevent name
space conflicts. That prefix will be "tep_".

This patch renames 'struct cmdline' to 'struct tep_cmdline'.

tools lib traceevent: Introduce new libtracevent API: tep_override_comm()

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

This patch adds a new API of tracevent library: tep_override_comm() It
registers a pid / command mapping. If a mapping with the same pid
already exists, the entry is updated with the new command.

tools lib traceevent: traceevent API cleanup

2018-12-17T17:56:10+00:00

In order to make libtraceevent into a proper library, its API should be
straightforward. This patch hides few API functions, intended for
internal usage only:

tep_free_event(), tep_free_format_field(), __tep_data2host2(),
__tep_data2host4() and __tep_data2host8().
The patch also alignes the libtraceevent summary man page with
these API changes.

tools lib traceevent: Rename tep_free_format() to tep_free_event()

2018-12-17T17:56:05+00:00

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. This renames tep_free_format() to tep_free_event(), which
describes more closely the purpose of the function.

tools lib traceevent: Implement new API tep_get_ref()

2018-12-17T17:55:52+00:00

This patch implements a new API of the tracevent library:

  int tep_get_ref(struct tep_handle *tep);

The API returns the reference counter "ref_count" of the tep handler.
As "struct tep_handle" is internal only, its members cannot be accessed
by the library users, the API is used to get the reference counter.

tools lib traceevent, perf tools: Move struct tep_handler definition in a local header file

2018-10-08T18:05:37+00:00

As traceevent is going to be transferred into a proper library,
its local data should be protected from the library users.
This patch encapsulates struct tep_handler into a local header,
not visible outside of the library. It implements also a bunch
of new APIs, which library users can use to access tep_handler members.
