In the test-runner, defines are parameterized constants (limited
to integers) that are generated from the test suite tomls resulting
in many permutations of each test.
In order to make this efficient, these defines are implemented as
multi-layered lookup tables, using per-layer/per-scope indirect
mappings. This lets the test-runner and test suites define their
own defines with compile-time indexes independently. It also makes
building of the lookup tables very efficient, since they can be
incrementally populated as we expand the test permutations.
The four current define layers and when we need to build them:
layer defines predefine_map define_map
user-provided overrides per-run per-run per-suite
per-permutation defines per-perm per-case per-perm
per-geometry defines per-perm compile-time -
default defines compile-time compile-time -
This moves defines entirely into the runtime of the test_runner,
simplifying thing and reducing the amount of generated code that needs
to be build, at the cost of limiting test-defines to uintmax_t types.
This is implemented using a set of index-based scopes (created by
test.py) that allow different layers to override defines from other
layers, accessible through the global `test_define` function.
layers:
1. command-line overrides
2. per-case defines
3. per-geometry defines
- Changed `make summary` to show a one line summary
- Added `make lfs.csv` rule, which is useful for finding more info with
other scripts
- Fixed small issue in ./scripts/summary.py
- Added *.ci (callgraph) and *.csv (script output) to CI
- Standardized littlefs debug statements to use hex prefixes and
brackets for printing pairs.
- Removed the entry behavior for readtree and made -t the default.
This is because 1. the CTZ skip-list parsing was broken, which is not
surprising, and 2. the entry parsing was more complicated than useful.
This functionality may be better implemented as a proper filesystem
read script, complete with directory tree dumping.
- Changed test.py's --gdb argument to take [init, main, assert],
this matches the names of the stages in C's startup.
- Added printing of tail to all mdir dumps in readtree/readmdir.
- Added a print for if any mdirs are corrupted in readtree.
- Added debug script side-effects to .gitignore.
This involved some minor tweaks for the various types of tests, added
predicates to the test framework (necessary for test_entries and
test_alloc), and cleaned up some of the testing semantics such as
reporting how many tests are filtered, showing permutation config on
the result screen, and properly inheriting suite config in cases.
