As the outerspace listeners catch read and write accesses, this must
be documented in the help message. The old parameter name is now marked as
deprecated and can be removed in 2022.
Furthmore, the experiment now has the combined command line argument
--catch-outerspace, which enables catching accesses below and above
the ELF.
If the user enabled multiple experiments, it does not make sense to
execute them concurrently. Therefore, we now only register all enabled
experiments and choose one experiment on fail-client startup. For this
selection, the user can either set the FAIL_EXPERIMENT environment
variable or invoke the tool with a specific argv[0]. For the
bin/-folder, we create symlinks for this mechanism.
With this change, the generic-tracing and generic-experiment can be
compiled into the same executable and we could distribute a "standard"
version of FAIL*.
As bigger changes lie ahead, we want a small end-to-end test suite
that ensures that our importing and tracing does not fall apart. With
this change, we add the infrastructure and two test-cases (fib, qsort)
including ELFs, traces, and injection results.
In order to run the basic-pruner test cases, one needs to setup a
MySQL table and set the CMake option ENABLE_DATABASE_TESTS.
The previous path google::protobuf::Message::Reflection was deprecated
in 2008 (779f61c6a3ce02a119e28e802f229e61b69b9046), and we only used
it here. With newer versions of proto-c, this breaks the build.
This is an API breaking change. Nevertheless, help text and
command-line parser were out of sync and the variant of the help-text
does make much more sense.
With the number of accessed memory addresses and the duration of the
trace, we can deduce the size of the rectangular memory fault space.
This will be used in testing.
