tests: modify f_large_dir test to excercise indexed dir handling

2020-03-15T16:33:23+00:00

Modify f_large_dir test to create indexed directory and create entries
in it. That way the new code in ext2fs_link() for addition of entries
into indexed directories gets executed including various special cases
when growing htree.

e2fsck: set dir_nlink feature if large dir exists

2018-06-22T22:08:54+00:00

If there is a directory with more than EXT2_LINK_MAX (65000)
subdirectories, but the DIR_NLINK feature is not set in the
superblock, the feature should be set before continuing on
to change the on-disk directory link count to 1.

While most filesystems should have DIR_NLINK set (it was set
by default for all ext4 filesystems, and all kernels between
2.6.23 and 4.12 automatically set it if the directory link
count grew too large), it is possible that this flag is lost
due to disk corruption or for an upgraded filesystem.  We no
longer want kernels to automatically enable features.

tests: don't run sed multiple times on test output

2018-06-22T21:59:35+00:00

Don't call sed multiple times on the output, and avoid the use
of temporary files, or if possible.  It would be convenient to
use "sed -i" to only update the output file once, but this is
not portable to all platforms.

tests: don't use "debugfs -f /dev/stdin"

2018-03-31T20:59:48+00:00

Don't use "debugfs -f /dev/stdin" for portability reasons --- not all
systems have /dev/stdin. Simply dropping "-f /dev/stdin" works just
fine.

tests: skip running long test with "make check" and add "make fullcheck"

2017-04-26T14:07:18+00:00

Don't run tests which take longer than 20 seconds to run (especially
f_large_dir, whose run time is well over ten minutes) for "make
check".  The new "make fullcheck" will run all of the regression tests
for e2fsprogs.

tests: fix bash'isms in f_large_dir

2017-04-26T05:05:56+00:00

Fix portability problems in the test script for f_large_dir.  Also
clean up messages that the script prints while it runs (and
unfortunately it takes a very long time to run).

tests: 3 level hash tree test

2017-04-13T15:53:40+00:00

Test is added that recreate directory (-fD fsck option)
with 47.5k of 255-symbol name files. This amount of files
can not be stored only in 2 hevel htree, so 3 levels are used.
