The changelog xlator was modified to use a poller thread, which uses
the same event pool as the xlator stack. Unfortunately, such threaded
usage of event pool is not supported by event-poll code, only
event-epoll supports it. As a result, platforms such as NetBSD that
lack epoll support got broken.
The fix is to remove the poller thread, which does not cause any
functionnality loss because the xlator stack event poll is
functionnal. That lets NetBSD pass AFR tests again.

Scrubber performs signature verification for objects that were
signed by signer. This is done by recalculating the signature
(using the hash algorithm the object was signed with) and
verifying it aginst the objects persisted signature. Since the
object could be undergoing IO opretaion at the time of hash
calculation, the signature may not match objects persisted
signature. Bitrot stub provides additional information about
the stalesness of an objects signature (determinted by it's
versioning mechanism). This additional bit of information is
used by scrubber to determine the staleness of the signature,
and in such cases the object is skipped verification (although
signature staleness is performed twice: once before initiation
of hash calculation and another after it (an object could be
modified after staleness checks).
The implmentation is a part of the bitrot xlator (signer) which
acts as a signer or scrubber based on a translator option. As
of now the scrub process is ever running (but has some form of
weak throttling mechanism during filesystem scan). Going forward,
there needs to be some form of scrub scheduling and IO throttling
(during hash calculation) tunables (via CLI).

This is the "Signer" -- responsible for signing files with their
checksums upon last file descriptor close (last release()).
The event notification facility provided by the changelog xlator
is made use of.
Moreover, checksums are as of now SHA256 hash of the object data
and is the only available hash at this point of time. Therefore,
there is no special "what hash to use" type check, although it's
does not take much to add various hashing algorithms to sign
objects with. Signatures are stored in extended attributes of the
objects along with the the type of hashing used to calculate the
signature. This makes thing future proof when other hash types
are added. The signature infrastructure is provided by bitrot
stub: a little piece of code that sits over the POSIX xlator
providing interfaces to "get or set" objects signature and it's
staleness.
Since objects are signed upon receiving release() notification,
pre-existing data which are "never" modified would never be
signed. To counter this, an initial crawler thread is spawned
The crawler scans the entire brick for objects that are unsigned
or "missed" signing due to the server going offline (node reboots,
crashes, etc..) and triggers an explicit sign. This would also
sign objects when bit-rot is enabled for a volume and/or after
upgrade.

Problem:
read-only/worm translator is not loaded by default in brick graph because of which
when read-only option is set through volume set volume still remains writable
untill the bricks are restarted as the translator does not have an inmemory flag
to decide whether the read-only/worm option is turned or not.
Solution:
read-only/worm should be loaded by default in brick graph and the read-only/worm
option can be toggled through volume set command. read-only/worm translator now'
has an in-memory flag to decide whether the volume is read-only or not and based
on that either reject the fop or proceed.

[WIP patch as of now, just needs a little tweak]
A pending TODO in the code caused regressions to fail as
bitrot daemons are spawned during volume start (equivalent
to enabling bitrot by default). The problematic part that
casued such failures is during brick disconnections with
unsafe handling of event data structured in the code.
With this patch, data structures are properly cleaned up
with care taken to cleanup all accessors first. This also
fixes potential memory leaks which was bluntly ignored
before.

Problem:
libgfchangelog initializes global xlator on library load (via
constructor: _ctor) and mangles it's xlator context thereby
messing with certain important members of the command structure.
On receiving an RPC disconnection event, if the point-of-execution
was in libgfchangelogs context, accessing ->cmd_args during RPC
notify resulted in a segfault.
Fix:
Since the libarary needs to be able to work with processes that
have a notion of an xlator (THIS in particular) and without it,
care needs to be taken to allocate the global xlator when needed.
Moreover, the actual fix is to use the correct xlator context
in both cases. A new API is introduces when needs to be invoked
by the conusmer (although this could have been done during
register() call, keeping it a separate API makes thing flexible
and easy).
Test:
The issue is observed when a brick process goes offline. This is
triggered when test cases (.t's) are run in bulk, since each
test essestially spawns bricks processes (on volume start) and
terminates them (volume stop). Since bitrot daemon, as of now,
spawns upon volume start, the issue is much observed when the
volume is taken offline at the end of each test case. With this
fix, running the basic and core test cases along with building
the linux kernel has passed without daemon segfaults.
Thanks to Johnny (rabhat@) for helping in debugging the issue
(and with the fix :)).

In the current code of trash translator, file is moved to
trash directory without checking whether it is the last
hardlink.This may lead to inconsistency for a file in that
gluster volume.To avoid those scenarios,so a file is moved
to trash directory only if it is the last hardlink.

Based on the high-level design by Anand V. Avati which can be found @
https://gist.github.com/avati/af04f1030dcf52e16535#sharding-xlator-stripe-20
Still to-do:
* complete implementation of inode write fops - [f]truncate,
zerofill, fallocate, discard
* introduce transaction mechanism in inode write fops
* complete readv
* Handle open with O_TRUNC
* Handle unlinking of all shards during unlink/rename
* Compute total ia_size and ia_blocks in lookup, readdirp, etc
* wind fsync/flush on all shards
Note: Most of the items above are related. Once we come up
with a clean way to determine the last shard/shard count for
a file/file size and the mgmt of sparse regions of the file,
implementing them becomes trivial.

This patch adds the arbiter translator into the tree. This is a server
side xlator used for replica 3 volumes. It sits above posix and will be
loaded on the 3rd (last) brick of every afr subvolume in a replica 3
configuration. It intercepts inode read/write operations: reads are
unwound with ENOTCONN, inode writes are unwound with success without
actually passing them down to posix. Metadata operations are allowed to
pass through.
The CLI for creating a 3 way replica with arbiter is also added but kept
disabled (A 'normal' 3 way replica is created instead).
This patch is a part of the arbiter logic implementation for 3 way AFR,
details of which can be found at http://review.gluster.org/#/c/9656/

**********************************************************************
ChangeTimeRecorder(CTR) Xlator |
**********************************************************************
ChangeTimeRecorder(CTR) is server side xlator(translator) which sits
just above posix xlator. The main role of this xlator is to record the
access/write patterns on a file residing the brick. It records the
read(only data) and write(data and metadata) times and also count on
how many times a file is read or written. This xlator also captures
the hard links to a file(as its required by data tiering to move
files).
CTR Xlator is the consumer of libgfdb.
To Enable/Disable CTR Xlator:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
gluster volume set <volume-name> features.ctr-enabled {on/off}
To Enable/Disable Frequency Counter Recording in CTR Xlator:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
gluster volume set <volume-name> features.record-counters {on/off}

This patch introduces RPC based communication between the changelog
translator and libgfchangelog. It replaces the old pathetic stream
based interaction that existed earlier (due to time constraints :-/).
Changelog, upon initialization starts a RPC server (rpcsvc) allowing
clients to invoke a probe API as a bootup mechanism to request for
event notifications. During probe, clients can choose an event
filter specifying the type(s) of events they are interested in. As
of now there is no way to change the event notification set once
the probe RPC call is made, but that is easier to implement.
The actual event notifications is done on a separate RPC session.
The client (libgfchangelog) itself starts and RPC server which the
changelog translator "connects back" during probe. Notifications
are dispatched by a bunch of threads from the server (translator)
and the client optionally orders them if ordered notifications
are requried. FOPs fill in their respective event details in a
buffer (rot-buffs to be particular) and a bunch of threads
(consumers) swap the buffers out of roatation and dispatch them
via RPC. To avoid writer starvation, then number of dispatcher
threads is one less than the number of buffer list in rot-buffs.x
libgfchangelog becomes purely callback based -- upon event
notification from the server (and re-ordering them if required)
invoke a callback routine specified by consumer(s).
A major part of the patch is also aimed at providing backward
compatibility for geo-replication, which was one of the main
consumer of the stream based API. Also, this patch does not\
"turn on" event notifications for all fops, just a bunch which
is currently in requirement. Another pain point is that the
server does not filter events before dispatching it to the
clients. That load is taken up by the client itself (although
it's done at the library layer rather than making it hard on
the callback implementor). This needs improvement and care
needs to be taken to not load the server up with expensive
filtering mechanisms.

Marker can fail or can account incorrect numbers when it doesn't find a
ancestry for a inode.
Solution:
Current build_ancestry is done only on demand in the write/create FOPs
in quota enforcer.
It is good to do this in the quota_lookup as well.

A dummy translator has been introduced as a place
holder for functions related to managing NFS-Ganesha
exports. A volume set option is introduced to
manage volume level exports.
gluster vol set <volname> ganesha.enable ON/OFF
1. gluster volume set <volname> ganesha.enable ON
It creates the export config file with a unique export ID.
Sends a DBus signal to export this volume dynamically.
2. gluster vol set <volname> ganesha.enable OFF
Unexports the specific volume. Deletes the specfic
config file related to the volume.
This change also removes the handling of the older
keys "nfs-ganesha.enable" and "nfs-ganesha.host"

Currently, the only way to retrieve the number of files/objects in a
directory or volume is to do a crawl of the entire directory/volume.
This is expensive and is not scalable.
The new mechanism proposes to store count of objects/files as part of
an extended attribute of a directory. Each directory's extended
attribute value will indicate the number of files/objects present
in a tree with the directory being considered as the root of the tree.
Currently file usage is accounted in marker by doing multiple FOPs
like setting and getting xattrs. Doing this with STACK WIND and
UNWIND can be harder to debug as involves multiple callbacks.
In this code we are replacing current mechanism with syncop approach
as syncop code is much simpler to follow and help us implement inode
quota in an organized way.

Normally a named-lookup is done by the kernel on an entry before it
issues a dentry creation fop like create/mknod etc. This will enable
cluster translators like dht to maintain internal consistency like
deleting a linkto file if no corresponding datafile is present etc.
While handling file creation on auxiliary gfid mounts, we issue dentry
creation fop without issuing a lookup. If there are stale-linkto files,
creation would fail with EEXIST, however access would fail since there
is no datafile. A named lookup would cleanup the linkto file allowing
create to succeed.

common ancestor of src and dst file

rename is split into link and unlink.
We need to handle quota_link properly.
We have fixed quota_rename in patch# 8940, we need to handle quota_link
similarly
> http://review.gluster.org/#/c/8940/
> quota: For a rename operation, do quota_check_limit only till the
> common ancestor of src and dst file
> Example:
> set quota limit set to 1GB on /
> create a file /a1/b1/file1 of 600MB
> mv /a1/b1/file1 /a1/b1/file2
> This rename fails as it takes delta into account which sums up to 1.2BG.
> Though we are not creating new file, we still get quota exceeded error.
> So quota enforce should happen only till b1.
> Similarly:
> mv /a/b/c/file /a/b/x/y/file
> quota enforce should happen only till dir 'b'

This is an improvement over the patch 'http://review.gluster.org/9337'
to trigger explicit geo-rep sync on regular files even if entry is not
present on the slave. An attempt is made to find the pargfid and
if available captures CREATE along with DATA in changelog.
CREATE is captured with default file permissions. Setting this virtual
setxattr on directories captures MKDIR in changelog. The value of
setxattr can be as follows.
If value = "1" : Both CREATE and DATA is captured in changelog if
pargfid is available, else on DATA is captured.
value = "any other: ENOTSUP is returned.
Usage:
setfattr -n glusterfs.geo-rep.trigger-sync -v "1" <file-path>
NOTE: This patch supports explicit record of entries only for
directories and regular files.

mv /a1/b1/file1 /a1/b1/file2
This rename fails as it takes delta into account which sums up to 1.2BG.
Though we are not creating new file, we still get quota exceeded error.
So quota enforce should happen only till b1.
Similarly:
mv /a/b/c/file /a/b/x/y/file
quota enforce should happen only till dir 'b'

1. Changed log messages to be more appropriate.
2. Changed loglevel of failures in fop_cbks to be recorded as TRACE.
Logging of failures at higher loglevels is unessential in non-endpoint
translators.
3. Removed a log message related to memory allocation failure.
