This is a new test runner to replace piglit. Piglit has been very
useful as a test runner, but certain improvements have been very
difficult if possible at all in a generic test running framework.
Important improvements over piglit:
- Faster to launch. Being able to make assumptions about what we're
executing makes it possible to save significant amounts of time. For
example, a testlist file's line "igt@somebinary@somesubtest" already
has all the information we need to construct the correct command
line to execute that particular subtest, instead of listing all
subtests of all test binaries and mapping them to command
lines. Same goes for the regexp filters command line flags -t and
-x; If we use -x somebinaryname, we don't need to list subtests from
somebinaryname, we already know none of them will get executed.
- Logs of incomplete tests. Piglit collects test output to memory and
dumps them to a file when the test is complete. The new runner
writes all output to disk immediately.
- Ability to execute multiple subtests in one binary execution. This
was possible with piglit, but its semantics made it very hard to
implement in practice. For example, having a testlist file not only
selected a subset of tests to run, but also mandated that they be
executed in the same order.
- Flexible timeout support. Instead of mandating a time tests cannot
exceed, the new runner has a timeout on inactivity. Activity is
any output on the test's stdout or stderr, or kernel activity via
/dev/kmsg.
The runner is fairly piglit compatible. The command line is very
similar, with a few additions. IGT_TEST_ROOT environment flag is still
supported, but can also be set via command line (in place of igt.py in
piglit command line).
The results are a set of log files, processed into a piglit-compatible
results.json file (BZ2 compression TODO). There are some new fields in
the json for extra information:
- "igt-version" contains the IGT version line. In
multiple-subtests-mode the version information is only printed once,
so it needs to be duplicated to all subtest results this way.
- "dmesg-warnings" contains the dmesg lines that triggered a
dmesg-warn/dmesg-fail state.
- Runtime information will be different. Piglit takes a timestamp at
the beginning and at the end of execution for runtime. The new
runner uses the subtest output text. The binary execution time will
also be included; The key "igt@somebinary" will have the runtime of
the binary "somebinary", whereas "igt@somebinary@a" etc will have
the runtime of the subtests. Substracting the subtest runtimes from
the binary runtime yields the total time spent doing setup in
igt_fixture blocks.
v2:
- use clock handling from igt_core instead of copypaste
- install results binary
- less magic numbers
- scanf doesn't give empty strings after all
- use designated array initialization with _F_JOURNAL and pals
- add more comments to dump_dmesg
- use signal in kill_child instead of bool
- use more 'usual' return values for execute_entry
- use signal number instead of magic integers
- use IGT_EXIT_INVALID instead of magic 79
- properly remove files in clear_test_result_directory()
- remove magic numbers
- warn if results directory contains extra files
- fix naming in matches_any
- construct command line in a cleaner way in add_subtests()
- clarify error in filtered_job_list
- replace single string fprintfs with fputs
- use getline() more sanely
- refactor string constants to a shared header
- explain non-nul-terminated string handling in resultgen
- saner line parsing
- rename gen_igt_name to generate_piglit_name
- clean up parse_result_string
- explain what we're parsing in resultgen
- explain the runtime accumulation in add_runtime
- refactor result overriding
- stop passing needle sizes to find_line functions
- refactor stdout/stderr parsing
- fix regex whitelist compiling
- add TODO for suppressions.txt
- refactor dmesg parsing
- fill_from_journal returns void
- explain missing result fields with TODO comments
- log_level parsing with typeof
- pass stdout/stderr to usage() instead of a bool
- fix absolute_path overflow
- refactor settings serialization
- remove maybe_strdup function
- refactor job list serialization
- refactor resuming, add new resume binary
- catch mmap failure correctly
v3:
- rename runner to igt_runner, etc
- add meson option for building the runner
- use UPPER_CASE names for string constants
- add TODO comments for future refactoring
- add a midding close()
- const correctness where applicable
- also build with autotools

TODO: Unit tests for the results.json file contents.
v2:
- Avoid writing the nul character to mock files
- Properly set up tmpdirs
v3:
- Restore the resume-related changes that were lost in rebase
v4:
- Better teardown for temporary directories
- Build with autotools
