feature/changelog: Fix changelog missing SETATTR entries.

2014-11-14T05:54:01+00:00

Problem: Valid SETATTR entries are missing in changelog when more
         than one metadata operation happen on same inode within
         changelog roll-over time.

Cause: Metadata entries with fop num being GF_FOP_NULL are logged
       in changelog which is of no use. Since slice version
       checking is done for metadata entries to avoid logging of
       subsequent entries of same inode falling into same
       changelog, if the entry with GF_FOP_NULL is logged first,
       subsequent valid ones will be missed.

Solution: Have a boundary condition to log only those fops whose fop
          number falls between GF_FOP_NULL and GF_FOP_MAXVALUE.

features/changelog: barrier all entry creation fops

2014-09-09T08:09:38+00:00

when a snapshot is taken, there are chances of entry creation fops
not being recorded either in changelog or through the recursive
ancestry xtime updation by marker. This causes consumers of changelog
(primarily geo-replication as of today) to not be aware of these entries
after a snapshot is restored. This can lead to inconsistencies. This patch
is an interim workaround to barrier creates till changelog becomes completely
crash consistent.

geo-rep/libgfchangelog: Create working dir during changelog_register if not present.

2014-09-08T17:42:25+00:00

Earlier, xysnc's register was being called first,
which was creating working directory before calling
changelog_register. Now it is history crawl first.
Hence working directory would not have been created.
Create it in gf_changelog_register itself if it is
not already created.

features/changelog: Capture "correct" internal FOPs

2014-09-08T17:21:17+00:00

This patch fixes changelog capturing internal FOPs in a cascaded
setup, where the intermediate master would record internal FOPs
(generated by DHT on link()/rename()). This is due to I/O happening
on the intermediate slave on geo-replication's auxillary mount with
client-pid -1. Currently, the internal FOP capturing logic depends
on client pid being non-negative and the presence of a special key
in dictionary. Due to this, internal FOPs on an inter-mediate master
would be recorded in the changelog. Checking client-pid being
non-negative was introduced to capture AFR self-heal traffic in
changelog, thereby breaking cascading setups. By coincidence,
AFR self-heal daemon uses -1 as frame->root->pid thereby making
is hard to differentiate b/w geo-rep's auxillary mount and self-heal
daemon.

build: make GLUSTERD_WORKDIR rely on localstatedir

2014-09-03T18:01:45+00:00

Backport from master branch - http://review.gluster.org/#/c/8246/

- Break-way from '/var/lib/glusterd' hard-coded previously,
  instead rely on 'configure' value from 'localstatedir'
- Provide 's/lib/db' as default working directory for gluster
  management daemon for BSD and Darwin based installations
- loff_t is really off_t on Darwin
- fix-off the warnings generated by clang on FreeBSD/Darwin
- Now 'tests/*' use GLUSTERD_WORKDIR a common variable for all
  platforms.
- Define proper environment for running tests, define correct PATH
  and LD_LIBRARY_PATH when running tests, so that the desired version
  of glusterfs is used, regardless where it is installed.
