* features/bit-rot-stub: implement mknod fopRaghavendra Bhat2015-05-311-15/+32
| | | | | | | | | | | | | | | | | | | With the absence of mknod() fop implementation in bitrot stub, further operations that trigger versioning resulted in crashes as they expect the inode context to be valid. Therefore, this patch implements mknod() following similar simantics to fops such as create(). Furthermore, bitrot stub test C program is fixed to stop lying and validate obj versions according to the versioning protocol.

* features/bit-rot-stub: versioning of objects in write/truncate fop instead ↵Raghavendra Bhat2015-05-081-9/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | of open * This patch brings in the changes where object versioning is done in write and truncate fops instead of tracking them in open and create fops. This model works for both regular and anonymous fds. It also removes the race associated with open calls, create and lookups. This patch follows the below method for object versioning and notifications: Before sending writev on the fd, increase the ongoing version first. This makes anonymous fd write similar to the regular fd write by having the ongoing version increased before doing the write. Do following steps to do versioning: 1) For anonymous fds set the fd context (so that release is invoked) and add the fd context to the list maintained in the inode context. For regular fds the above think would have been done in open itself. 2) Increase the on-disk ongoing version 3) Increase the in memory ongoing version and mark inode as non-dirty 3) Once versioning is successfully done send write operation. If versioning fails, then fail the write fop. 5) In writev_cbk mark inode as modified.

* tests/bitrot-stub: Object versioning test(s)Venky Shankar2015-04-081-0/+147
This patch introduces basic object versioning test(s) which is required for bitrot detection to work correctly. Basic test(s) such as opening a file in read-only mode, single open, multiple open()s are covered on FUSE mount _only_ as stub does not support anonymous fds yet. For this reason, the test case disables open-behind. Actual verification is implemented as a C source which makes use of the same on-disk data structures as used by the stub code. The data structures are moved to separate header file which is included by the test script. Such modularization helps in future enhancements to keep the version "data type" opaque and provide handful of APIs version checking (equal/greater/etc..). [ This is just a start and should grow over time as stub is enhanced and codebase matures. ] Change-Id: Ibee20e65a15b56bbdd59fd2703f9305b115aec7a BUG: 1201724 Signed-off-by: Venky Shankar <vshankar@redhat.com> Reviewed-on: http://review.gluster.org/10140 Reviewed-by: Raghavendra Bhat <raghavendra@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>
