tests: Backport all changes to tests dir

2016-05-04T18:47:11+00:00

Test framework should be the same on all the branches. This is a copy
of all the files under tests dir from master branch. New tests in
master have not been backported, but changes to existing tests have
been.

tests: Fix sparse-file-self-heal.t

2016-01-25T11:36:32+00:00

Backport of http://review.gluster.org/13233
Psuedo Problem:
https://build.gluster.org/job/rackspace-regression-2GB-triggered/16682/consoleFull

The 'zeroedfile' disk usage comparision which is failing in this .t file
fails so only on XFS. The test passes when the backend is on a s̶a̶n̶e̶r̶
different filesystem like EXT4 or BTRFS. This is due to the speculative
preallocation in XFS which can reserve different disk space on different
XFS mounts for the same version and same file operation. See BZ 1277992
for an example of XFS behaviour.

Fix:
Don't compare the disk usage of the file on the bricks of the replica:
instead, check that the disk space consumed is atleast equal to the size
of the file.

Also remove sparse-file-self-heal.t from is_bad_test()

afr: write zeros to sink for non-sparse files

2015-10-29T08:40:19+00:00

Backport of http://review.gluster.org/#/c/12371/
Problem: If a file is created with zeroes ('dd', 'fallocate' etc.) when
a brick is down, the self-heal does not write the zeroes to the sink
after it comes up. Consequenty, there is a mismatch in disk-usage
amongst the bricks of the replica.

Fix: If we definitely know that the file is not sparse, then write the
zeroes to the sink even if the checksums match.

afr: Don't write to sparse regions of sink.

2015-01-30T12:02:43+00:00

Problem:
When data-self-heal-algorithm is set to 'full', shd just reads from
source and writes to sink. If source file happened to be sparse (VM
workloads), we end up actually writing 0s to the corresponding regions
of the sink causing it to lose its sparseness.

Fix:
If the source file is sparse, and the data read from source and sink are
both zeros for that range, skip writing that range to the sink.

porting: various fixes regression tests OSX/FreeBSD

2014-08-29T16:13:02+00:00

- `wc -l` on OSX/FreeBSD adds spurious spaces, this clobbers
  up TAP output parsers - fix it.
- `umount -l` doesn't exist on OSX/FreeBSD use 'umount -f' if
   available.
- Add check for 'file' version, to handle mime type variations
  across versions
- Converge 'glusterfs --attribute-timeout=0 --entry-timeout=0'
  into '$GFS'
- Modify remaining 'mount -t nfs' to use 'mount_nfs'
- Update sha1sum for OSX to use 'openssl sha1'.

Regression test portability: dd usage

2014-07-14T13:29:15+00:00

NetBSD, FreeBSD, and MacOS X dd(1) bs argument uses m for megabyte, while
Linux uses M. Use bs=1024k instead of bs=1M for better compatibility.
