The dciao-kernelstructs experiment does a trace imported by the
DCiAOKernelImporter:
bin/import-trace -t trace.pb -i DCiAOKernelImporter --elf-file app.elf
Pruned by the basic method:
bin/prune-trace
and does CiAO fault injection experiments, where the results are
stored in the database.

The DatabaseCampaign interacts with the MySQL tables that are created
by the import-trace and prune-trace tools. It does offer all
unfinished experiment pilots from the database to the
fail-clients. Those clients send back a (by the experiment) defined
protobuf message as a result. The custom protobuf message does have to
need the form:
import "DatabaseCampaignMessage.proto";
message ExperimentMsg {
required DatabaseCampaignMessage fsppilot = 1;
repeated group Result = 2 {
// custom fields
required int32 bitoffset = 1;
optional int32 result = 2;
}
}
The DatabaseCampaignMessage is the pilot identifier from the
database. For each of the repeated result entries a row in a table is
allocated. The structure of this table is constructed (by protobuf
reflection) from the description of the message. Each field in the
Result group becomes a column in the result table. For the given
example it would be:
CREATE TABLE result_ExperimentMessage(
pilot_id INT,
bitoffset INT NOT NULL,
result INT,
PRIMARY_KEY(pilot_id)
)

The import tool does support the following import strategies:
- BasicImporter: generates def-use equivalence classes for read and
write memory accesses
- DCiAOKernelImporter: generates equivalence classes for read access in
the ciao kernel space.
