The main benefit is small test ids everywhere, though this is with the
downside of needing longer names to properly prefix and avoid
collisions. But this fits into the rest of the scripts with globally
unique names a bit better. This is a C project after all.
The other small benefit is test generators may have an easier time since
per-case symbols can expect to be unique.
This mostly required names for each test case, declarations of
previously-implicit variables since the new test framework is more
conservative with what it declares (the small extra effort to add
declarations is well worth the simplicity and improved readability),
and tweaks to work with not-really-constant defines.
Also renamed test_ -> test, replacing the old ./scripts/test.py,
unfortunately git seems to have had a hard time with this.
- Added caching to Travis install dirs, because otherwise
pip3 install fails randomly
- Increased size of littlefs-fuse disk because test script has
a larger footprint now
- Skip a couple of reentrant tests under byte-level writes because
the tests just take too long and cause Travis to bail due to no
output for 10m
- Fixed various Valgrind errors
- Suppressed uninit checks for tests where LFS_BLOCK_ERASE_VALUE == -1.
In this case rambd goes uninitialized, which is fine for rambd's
purposes. Note I couldn't figure out how to limit this suppression
to only the malloc in rambd, this doesn't seem possible with Valgrind.
- Fixed memory leaks in exhaustion tests
- Fixed off-by-1 string null-terminator issue in paths tests
- Fixed lfs_file_sync issue caused by revealed by fixing memory leaks
in exhaustion tests. Getting ENOSPC during a file write puts the file
in a bad state where littlefs doesn't know how to write it out safely.
In this case, lfs_file_sync and lfs_file_close return 0 without
writing out state so that device-side resources can still be cleaned
up. To recover from ENOSPC, the file needs to be reopened and the
writes recreated. Not sure if there is a better way to handle this.
- Added some quality-of-life improvements to Valgrind testing
- Fit Valgrind messages into truncated output when not in verbose mode
- Turned on origin tracking
- Removed old tests and test scripts
- Reorganize the block devices to live under one directory
- Plugged new test framework into Makefile
renamed:
- scripts/test_.py -> scripts/test.py
- tests_ -> tests
- {file,ram,test}bd/* -> bd/*
It took a surprising amount of effort to make the Makefile behave since
it turns out the "test_%" rule could override "tests/test_%.toml.test"
which is generated as part of test.py.
