Fix babeltrace-log(1) for Babeltrace 2

This fixes babeltrace-log(1) so that it works with the Babeltrace 2
tree.

What the program does now is to parse its arguments, create the
arguments to be passed to the babeltrace(1) CLI tool, and spawn a
babeltrace(1) process to build and run a processing graph.

babeltrace-log(1) executes babeltrace(1) as such:

    babeltrace run --component dmesg:src.text.dmesg --params read-from-stdin=yes
                   --params no-extract-timestamp=yes --component ctf:sink.ctf.fs
                   --key path --value /output/path --connect dmesg:ctf

`no-extract-timestamp=yes` becomes `no-extract-timestamp=no` with
babeltrace-log(1)'s -t/--with-timestamps option. The standard input is
forwarded to the child process.

Like babeltrace(1), the build system creates both babeltrace-log and
babeltrace-log.bin executables. The former spawns the in-tree
babeltrace(1) tool while the latter spawns the installed version.

Automatically generate discarded packets/events notifications

This patch adds discarded packets and events notifications. Those
notifications are automatically generated by each notification iterator
by looking at packet header (PH) field's `packet_seq_num` and packet
context (PC) field's `events_discarded` fields to keep track of the
current state. Automatically generating those notifications, and
forbidding the user to create them, allows them to always be
synchronized with the values of the PH and PC special fields, and
guarantees to the user that they are generated whenever there is a
change in those values.

Each notification contains a count, an optional beginning clock value,
and an optional ending clock value, as well as a stream in which the
elements are discarded by the tracer.

As of this patch, flt.utils.trimmer does not reset the value of its
copied `packet_seq_num` and `events_discarded` fields to 0, and this is
probably a bug because a notification iterator on an flt.utils.trimmer
component can see discarded packets or events notifications before the
first packet beginning notification (which should not be the case if we
consider that a trimmed stream should act like a stream which originally
had those time bounds).

The sink.text.pretty component does not do anything specific with those
new notifications yet, but they are expected to be used to replicate
Babeltrace 1's behaviour (printing warnings).

Philippe Proulx [Fri, 16 Jun 2017 01:36:57 +0000 (21:36 -0400)] 
ctf: remove strict metadata mode, update automatic CC mapping behaviour

Update the automatic mapping of specific fields to clock classes when
no explicit mapping is found in the integer field type to follow this:

                     | 0 CCs             | 1 CC             | 2+ CCs
    --------------------------------------------------------------------
    FT is mapped     | Unreachable       | OK as is         | OK as is
    FT is not mapped | Map to auto 1 GHz | Map to single CC | Error

The (FT is not mapped, 0 CC) cell follows Babeltrace 1's behaviour: when
a special timestamp field is found in the packet context
(`timestamp_begin` or `timestamp_end`) or event header (`timestamp`)
scope, when this timestamp field is not explicitly mapped to a clock
class, and when there's no clock class at this point in the trace, then
create an automatic, 1 GHz clock class and, in this case, name it
`default`. Map the field to this implicit 1 GHz clock class. See
section 8 ("Clocks") of CTF v1.8.2.

Cell (FT is not mapped, 0 CC) is a fix for old versions of LTTng, and
cell (FT is not mapped, 1 CC) is a fix for old versions of CTF writer.
Cell (FT is not mapped, 2+ CCs) is an error because we wouldn't know
which clock class to automatically map the field to.

7 years agoRemove the concept of event class attributes
Philippe Proulx [Thu, 15 Jun 2017 22:38:45 +0000 (18:38 -0400)] 
Remove the concept of event class attributes

The concept of event class attributes could be confusing with the
eventual concept of user attributes to be introduced in CTF 2. This is
not strictly required for Babeltrace 2.0: we can create dedicated
accessors for CTF 1.8 attributes (ID, name, log level, EMF URI). This is
what this patch does, removing the attributes API and adding:

* bt_ctf_event_class_get_log_level()
* bt_ctf_event_class_set_log_level()
* bt_ctf_event_class_get_emf_uri()
* bt_ctf_event_class_set_emf_uri()

There are already accessors for the name and ID attributes. As to the
stream class ID (`stream_id`) attribute, it should never have existed in
the first place because you can always use the parent stream class's ID.
Thus this patch also fixes a bug where there was a synchronization
problem between a stream class's ID and the `stream_id` attribute of its
contained event classes.

The bt_ctf_event_class_get_log_level() and
bt_ctf_event_class_set_log_level() functions use the new
`enum bt_ctf_event_class_log_level` enumeration which contains all the
log levels of LTTng-UST, which happen to be CTF 1.8's log levels too
because Babeltrace 1 prints those names for those values whatever the
trace's producer. A translation is performed from the numeric values to
this enumeration in plugins/ctf/common/metadata/visitor-generate-ir.c,
and the reverse is done in plugins/text/pretty/print.c. Knowing this,
the `loglevel_string` attribute that visitor-generate-ir.c used to add
to event classes (and which plugins/text/pretty/print.c used to
pretty-print the names) is removed. This was also an issue because
Babeltrace 1 does not know `loglevel_string` and sink.ctf.fs, through
the CTF writer implementation, was serializing this attribute in the
generated metadata.

tests/lib/test_ctf_writer.c is updated to test the individual accessors
instead of the generic attribute API.

plugins/libctfcopytrace/ctfcopytrace.c is updated to copy the known
attributes intead of using the generic attribute API.

Fix: Stream classes' id field is always serialized

A stream class' "id" must not be expressed in the trace metadata
if the trace's packet header does not contain a stream_id field.
Otherwise, the reader will try to ensure the packets' stream_id
corresponds to the stream class' id and will fail to do so.

The fix is to omit the serialization of the stream class' id
field entirely if the stream_id field is not found within the
trace's packet header.

It remains unclear whether or not a stream class has an actual
"id" in this case, or if some "unspecified" id state should
be implemented.
