This change converts all the existing regression tests in
regress/sys/fs/tmpfs to the new framework provided by atf. As a side
effect, this also moves all the tests programs in regress/sys/fs/tmpfs to
tests/fs/tmpfs.
1) Renaming a directory to an empty directory works by replacing the target
directory.
2) Renaming a directory to a non-empty directory fails.
This is all by calling rename(2) directly, not mv(1).
tmpfs currently fails those tests, raising an assertion if DIAGNOSTIC is
enabled. A fix will hopefully follow soon.

operation. These all match the behavior exposed by MFS (except for a
corner case that is described in t_link).
Fixes to tmpfs itself to make these tests pass will come soon.
/var/log/messages file wich is most likely not interesting but the
regression test can work on every specified filingsystem by passing a file
on that filingsystem to it as argument.
It tests:
- initial position
- seeking absolute position
- seeking end
- seeking negative relative position
more can be added later.
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.
While touching all vptofh/fhtovp functions, get rid of VFS_MAXFIDSIZ,
version the getfh(2) syscall and explicitly pass the size available in
the filehandle from userland.
Discussed on tech-kern, with lots of help from yamt (thanks!).
particular, the caller can now choose whether to wait for the condition
to be met, and if the caller of LFCNWRAPSTOP dies or otherwise closes
the descriptor, the filesystem is started again. Updated the ckckp
regression test to use the new semantics.
dump_lfs(8) now uses the fcntls to implement LFS-style snapshotting through
the -X flag, addressing PR#33457 albeit not using fss(4). Fixed a couple
other problems with dump_lfs that manifested themselves during testing.
Move the stop for LFCNWRAPSTOP to the point at which writing at segment 0
is really about to commence, since this is what the test expects (and
incidentally what a snapshotting utility wants as well).
More correctly reconstruct the on-disk state at every checkpoint, rather
than relying on the entire state at the point of wrapping to be accurate
(that is only true the first time we wrap). Add a "make abort" target to
make rerunning the test more convenient when it has failed and we're done
analyzing the failure.
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.
in a 64-bit signed integer (thus ensuring that mount_tmpfs handles these
correctly).
Also check that the previous (big) value fails.
This makes this test behave correctly on all platforms (not only 64-bit
ones) after the fix commited to mount_tmpfs.
tmpfs' "API" and was already rotting.
Instead, merge all the relevant comments into the code. This includes
acknowledgements to Google's Summer of Code 2005 program (they were in the
AUTHORS section of tmpfs(9) before), so all the files need to be changed
to include this sentence alongside the title. (Note that this was not a
requirement of the program.)
