tests: don't use a sparse test file
If the TEST_BITS file is sparse, then the "debugfs -R write" command may skip holes in the file when copying it into the test image (depending on whether SEEK_HOLE/SEEK_DATA and/or FIEMAP are available in the copy_file() function). This was causing test failures on MacOS in the f_dup_resize and d_loaddump tests because the TEST_BITS file was the compiled "debugfs" binary, which apparently has holes when built on MacOS, and the number of blocks allocated in the test image was reduced as a result. This caused the expect output to differ in the summary line and resulted in failure. Instead of using the debugfs binary for TEST_BITS, generate a temporary file using /dev/urandom, if available. If not, fall back to the old behaviour or using debugfs. [ Fixed up use of non-POSIX /bin/sh constructs and add test_data.tmp to .gitignore and files to be deleted on a make clean. --tytso ] Signed-off-by: Andreas Dilger <adilger@dilger.ca> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
