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.

6 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.

6 years agoctf: add metadata decoder config. and `strict-metadata` param in src.ctf.fs
Philippe Proulx [Wed, 14 Jun 2017 15:15:00 +0000 (11:15 -0400)] 
ctf: add metadata decoder config. and `strict-metadata` param in src.ctf.fs

The common metadata decoder now accepts an optional configuration
structure. The offset (seconds and nanoseconds) to apply to all the
clock classes is found in there, as well as a new option which makes the
decoder strict. In strict mode, the decoder does not allow the decoded
metadata stream to be off semantically. For example, in strict mode,
clock classes named `monotonic` are not forced to be absolute when it is
detected that the stream was produced by an LTTng tracer.

It's not expected that the strict mode be something that any user would
want under normal conditions because the non-strict mode fixes errors
made by known tracers to make things work for the other components of
the graph. As such, there's no quick --strict option in the CLI's
`convert` command: the user can instantiate its own source.ctf.fs
component with --component for this and pass the options with --params:

    babeltrace -c src.ctf.fs --path ~/my-traces/trace -p strict-metadata=yes

I'm also fixing the parameter names and types for the clock class
offsets, both in the CLI and in source.ctf.fs, so that all the project's
modules are in sync regarding this. The parameters are now
`clock-class-offset-s` and `clock-class-offset-ns`, and with the
`convert` command, they are set with resp. --clock-offset and
--clock-offset-ns. They used to be passed to the `run` command as string
values (using --key and --value), but now they are part of the
component's --params option so that they are recognized as constant
integer values (even if negative).

6 years agocli: add global --log-level option
Philippe Proulx [Wed, 14 Jun 2017 05:17:23 +0000 (01:17 -0400)] 
cli: add global --log-level option

This new global option (applies before the command name) sets the
default log level of all the known (project's) loggers. This default
log level can still be overridden by a specific environment variable,
for example:

    BABELTRACE_PLUGIN_CTF_METADATA_LOG_LEVEL=D babeltrace --log-level=I ...

In this example, all the log levels are set to INFO, but
BABELTRACE_PLUGIN_CTF_METADATA_LOG_LEVEL overrides the `ctf` plugin's
metadata module's log level to DEBUG.

When you don't specify --log-level, it defaults to W (WARN), the current
behaviour.

--verbose is now the equivalent of --log-level=I, and --debug is the
equivalent of --log-level=V. --verbose and --debug do the same thing,
for the `convert` command, whether they are global or specific to the
command. --verbose and --debug can still be specified together, and
whatever the order, the lowest log level always wins: VERBOSE.
The --log-level option can override previous --verbose, --debug, or
--log-level options because it didn't exist in Babeltrace 1 anyway so
there's no way to break backward compatibility:

    babeltrace --log-level=W --verbose --log-level=E ...

In this case, the final log level is ERROR.

Other example with implicit `convert` command:

    babeltrace --log-level=E /path/to/trace -v

In this case, the command's --verbose option sets the log level to
INFO because it's lower than ERROR (set by --log-level=E).

One of the main use cases of the new --log-level option is to completely
disable logging:

it static as well.

This is also true when we open the trace and it is already static.

cli: use -o ctf --output /output/path to quickly instantiate sink.ctf.fs

This should be easier for existing users of Babeltrace 1 which are used
to the --output-format (-o) and --output (-w) options. We had people
previously on the mailing list asking why

    babeltrace my-trace -o ctf --output /output/path

was not working. The answer is that there was no CTF sink at the time,
but this usage is still correct and straightforward.

The code makes sure that, if something implies `-o text`, for example
--names, --fields, or --no-delta, then you cannot use this form because
--output could also apply to the implicit sink.pretty.text component. We
also make sure that --output exists if `-o ctf` exists (--output without
`-o ctf` applies to the implicit `-o text` as mentioned previously).

The run command equivalent of this command:

    babeltrace my-trace -o ctf --output /output/path

as returned by --run-args, is:

    babeltrace run --component source.ctf.fs --name source-ctf-fs
                   --key path --value my-trace --component sink.ctf.fs
                   --name sink-ctf-fs --key path --value /output/path
                   --component filter.utils.muxer --name muxer
                   --component filter.lttng-utils.debug-info
                   --name debug-info --connect source-ctf-fs:muxer
                   --connect muxer:debug-info
                   --connect debug-info:sink-ctf-fs

tests/cli/test_convert_args is updated because the preferred name of the
implicit source.ctf.fs component is changed: it used to be `ctf-fs`,
it's now `source-ctf-fs`, as the preferred implicit sink.ctf.fs
component's name is `sink-ctf-fs`. Also there are a few more tests to
verify the constraint and generated options mentioned in this message.

This patch makes a filter.utils.muxer component's notification iterator
set what properties it expects from future clock classes from the first
clock classes it checks. The possible expectations are:

* Expect absolute clock classes, any UUID.
* Expect non-absolute clock classes, without a UUID.
* Expect non-absolute clock classes, with a specific UUID.

With this patch you can make the component mux the streams of a single
trace of which the clock is not absolute, or has no UUID.

The `assume-absolute-clock-classes` parameter overrides all those
