libtraceevent: 1.8.0
Changes since 1.7.3:
New APIs:
tep_record_is_event() - A helper function that basically converts
int type= tep_data_type(event->tep, record);
if (event->id == type) {
/* do something */
}
into:
if (tep_record_is_event(record, event)) {
/* do something */
}
tep_get_sub_buffer_commit_offset() - Add a function to return the
offset of where the "commit" is located on the subbuffer
so that the application can do its own direct reading of it.
kbuffer_read_buffer() - Add the functionality to the kbuffer to
act like the read syscall of the ring buffer. That is, it
will load the passed in buffer with the events where the
kbuffer left off, and that passed in buffer can be loaded
into another kbuffer via kbuffer_load_subbuffer().
kbuffer_dup() - Create a new kbuffer with the same fields of an
existing kbuffer. This will allow traversing a subbuffer
without modifying the contents of another kbuffer that
points to the subbuffer.
kbuffer_subbuffer() - Return the subbuffer that was loaded into
a kbuffer via kbuffer_load_subbuffer().
kbuffer_refresh() - In the case of the subbuffer that was loaded
into a kbuffer via kbuffer_load_subbuffer() that is still
active, this function will refresh the meta data to continue
reading events if more were written to it.
Updates:
- Add option to disable building documents for some environments
that do not have everything needed to build the documents to
not fail the build with meson.
- Bump meson version required to build to 0.58.0 as plugins use
str.replace that was introduced in that version.
- Have the sched_switch plugin parse the format field to figure out
what the correct mapping of the "prev_state" field is to produce
the proper string output.
Fixes:
- Update the default sched_switch "prev_state" string array to match
what's been in the kernel for a while now.
- Fix tep_kbuffer() to fill in the long_size, otherwise it would default
to 32 bit longs and cause a lot of confusion to application developers
(as well as myself!).
