- 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
