RevisionDateAuthorComments
 1.7  28-Apr-2008  martin Remove clause 3 and 4 from TNF licenses
 1.6  21-Jul-2006  perseant branches: 1.6.18;
Include testing of the roll-forward agent, when recreating the filesystem
partial-segment by partial-segment. Each checkpoint should pass fsck_lfs -n
without errors; the results of fsck_lfs -p on non-checkpoints should also
pass fsck_lfs -n without errors.
 1.5  05-May-2006  perseant Tabify.
 1.4  05-May-2006  perseant Allow the user to specify a file size in the ckckp regression test, including
the value zero (filling the filesystem with directories and empty file
inodes).
 1.3  01-May-2006  perseant Remember to empty the filesystem between iterations, otherwise all
iterations after the first are no-ops.
 1.2  27-Apr-2006  perseant Be a little more careful about what we copy into the working file when;
this takes care of another class of false positives. Add copyright
assignments.
 1.1  17-Apr-2006  perseant Introduce two fcntl calls that freeze the filesystem right at the point
where segment 0 is being considered for writing. This allows for automated
checkpoint vailidity scanning, and could be used (in conjunction with the
existing LFCNREWIND) for e.g. snapshot dumps as well.

Include a regression test that does such scanning.

When writing the Ifile, loop through the dirty block list three times to
make sure that the checkpoint is always consistent (the first and second
times the Ifile blocks can cross a segment boundary; not so the third time
unless the segments are very small). Discovered by using the aforementioned
regression test.
 1.6.18.1  18-May-2008  yamt sync with head.
