And minor cleanup of a few of the Makefile.am files while we're
at it.
Rewrite the make rules to do what xdrgen does. Now we can get rid
of xdrgen.
Note 1. netbsd6's sed doesn't do -i. Why are we still running
smoke tests on netbsd6 and not netbsd7? We barely support netbsd7
as it is.
Note 2. Why is/was libgfxdr.so (.../rpc/xdr/src/...) linked with
libglusterfs? A cut-and-paste mistake? It has no references to
symbols in libglusterfs.
Note3. "/#ifndef\|#define\|#endif/" (note the '\'s) is a _basic_
regex that matches the same lines as the _extended_ regex
"/#(ifndef|define|endif)/". To match the extended regex sed needs to
be run with -r on Linux; with -E on *BSD. However NetBSD's and
FreeBSD's sed helpfully also provide -r for compatibility. Using a
basic regex avoids having to use a kludge in order to run sed with
the correct option on OS X.
Note 4. Not copying the bit of xdrgen that inserts copyright/license
boilerplate. AFAIK it's silly to pretend that machine generated
files like these can be copyrighted or need license boilerplate.
The XDR source files have their own copyright and license; and
their copyrights are bound to be more up to date than old
boilerplate inserted by a script. From what I've seen of other
Open Source projects -- e.g. gcc and its C parser files generated
by yacc and lex -- IIRC they don't bother to add copyright/license
boilerplate to their generated files.
It appears that it's a long-standing feature of make (SysV, BSD,
gnu) for out-of-tree builds to helpfully pretend that the source
files it can find in the VPATH "exist" as if they are in the $cwd.
rpcgen doesn't work well in this situation and generates files
with "bad" #include directives.
E.g. if you `rpcgen ../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.x`,
you get an #include directive in the generated .c file like this:
...
#include "../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.h"
...
which (obviously) results in compile errors on out-of-tree build
because the (generated) header file doesn't exist at that location.
Compared to `rpcgen ./glusterfs3-xdr.x` where you get:
...
#include "glusterfs3-xdr.h"
...
Which is what we need. We have to resort to some Stupid Make Tricks
like the addition of various .PHONY targets to work around the VPATH
"help".
Warning: When doing an in-tree build, -I$(top_builddir)/rpc/xdr/...
looks exactly like -I$(top_srcdir)/rpc/xdr/... Don't be fooled though.
And don't delete the -I$(top_builddir)/rpc/xdr/... bits

The rebalance process will now send an event when it is
complete.
Also fixed a problem where the run-time was not always
set causing spurious rebalance failure events to be sent.

Currently, for all the update operations, metadata or data,
we set the dirty flag at the end of the operation only if
a brick is down. This leads to delay in healing and in some
cases not at all.
In this patch we set (+1) the dirty flag
at the start of the metadata or data update operations and
after successfull completion of the fop, we unset (-1) it again.

Problem: In a distributed-replicate volume attribute
"replica.split-brain-status" value does not display split-brain
condition though directory is in split-brain.
If directory is in split brain on mutiple replica-pairs
it does not show full list of replica pairs.
Solution: Update the dht_aggregate code to aggregate the xattr
value in this specific condition.
Fix: 1) function getChoices returns the choices from split-brain
status string.
2) function add_opt adding the choices to local buffer to
store in dictionary
3) For the key "replica.split-brain-status" function dht_aggregate
call dht_aggregate_split_brain_xattr to prepare the list.
Test: To verify the patch followed below steps
1) Create a distributed replica volume and create mount point
2) Stop heal daemon
3) Touch file and directories on mount point
mkdir test{1..5};touch tmp{1..5}
4) Down brick process on one of the replica set
pkill -9 glusterfsd
5) Change permission of dir on mount point
chmod 755 test{1..5}
6) Restart brick process on node with force option
7) kill brick process on other node in same replica set
8) Change permission of dir again on mount point
chmod 766 test{1..5}
9) Reexecute same step from 4-9 on other replica set also
10) After check heal status on server it will show dir's are
in split brain on all replica sets
11) After check the replica.split-brain-status attr on mount
point it will show wrong status of split brain.
12) After apply the patch the attribute shows correct value.

Post add-brick event the new brick will have permission of 755
by default. If the root directory permission was other than 755,
that does not get healed to the new brick leading to permission
errors/inconsistencies.
For choosing source of attr heal we can trust the subvols which
have layouts with latest ctime(as part of missing directory heal,
we heal the proper attr). In case none of the subvols have layout,
return ESTALE to retrigger a fresh lookup.
Note: This patch heals the permission of the root directories only.
Since, permission healing of directory is not straight forward and
required intrusive fix, those are not addressed here.

Problem: For healing of uid/gid we check if local->stbuf.ia_ctime is
lesser than stbuf->ia_ctime (received from brick). If yes then uid/gid
is updated to local->prebuf(source of healing).
But we merge local->stbuf also form the newly added brick. So if we
receive response from the newly added brick first and update the
local->stbuf, then local->prebuf will remain empty since the newly added
brick will have the latest ctime among all servers. And this can result
in healing wrong uid/gids to the rest of servers.
Hence, we should update local->stbuf from servers with a layout which
will ignore merging stbufs from newly added bricks.

This patch implements functionalities for fast encoding/decoding
using hardware support. Currently optimized x86_64, SSE and AVX is
added.
Additionally this patch implements a caching mecanism for inverse
matrices to reduce computation time, as well as a new method for
computing the inverse that takes quadratic time instead of cubic.
Finally some unnecessary memory copies have been eliminated to
further increase performance.

Problem: As metadata in the database fills up, querying the database
take a long time. As a result, tier migration slows down. To
counteract this, we added a way to enable the compaction methods of
the underlying database. The goal is to reduce the size of the
underlying file by eliminating database fragmentation.
NOTE: There is currently a bug where sometimes a brick will
attempt to activate compaction. This happens even compaction is already
turned on.
The cause is narrowed down to the compact_mode_switch flipping its value.
Changes: libglusterfs/src/gfdb - Added a gfdb function to compact the
underlying database, compact_db() This is a no-op if the database has
no such option.
- Added a compaction function for SQLite3 that does the following
1) Changes the auto_vacuum pragma of the database
2) Compacts the database according to the type of compaction requested
- Compaction type can be changed by changing the macro
GF_SQL_COMPACT_DEF to one of the 4 compaction types in
gfdb_sqlite3.h
It is currently set to GF_SQL_COMPACT_INCR, or incremental
vacuuming.
xlators/cluster/dht/src - Added the following command-line option to
enable SQLite3 compaction.
gluster volume set <vol-name> tier-compact <off|on>
- Added the following command-line option to change the frequency the
hot and cold tier are ordered to compact.
gluster volume set <vol-name> tier-hot-compact-frequency <int>
gluster volume set <vol-name> tier-cold-compact-frequency <int>
- tier daemon periodically sends the (new)
GFDB_IPC_CTR_SET_COMPACT_PRAGMA IPC to the CTR xlator. The IPC
triggers compaction of the database.
The inputs are both gf_boolean_t.
IPC Input:
compact_active: Is compaction currently on for the db.
compact_mode_switched: Did we flip the compaction switch recently?
IPC Output:
0 if the compaction succeeds.
Non-zero otherwise.
xlators/features/changetimerecorder/src/ - When the CTR gets the
compaction IPC, it launches a thread that will perform the
compaction. The IPC ends after the thread is launched. To avoid extra
allocations, the parameters are passed using static variables.

Issue:
dht_layout is built as a part of lookup only. The layout can be
modified by rebalance process. Since every IO fop is preceded
by a lookup, there are very less issues of stale layout. But
with enhancements of aggressive caching of stats in md-cache,
the lookup will reduce and expose the stale layout issue often.
Solution:
Since stale layout is already an issue on dht, there is already
a plan to fix this at the dht layer, but this fix is not currently
planned for any release. Until this fix comes out, we can have
a workaround where, the upcall will send a notification to md-cache
when a layout xattr is changed. As a part of layout change notification
the existing cache is invalidated and the next lookup will fetch the
latest layout.
This is not a foolproof solution as the window between the layout change
and the next lookup(after invalidation of stat), where there will be stale
layout. But until the final fix comes in, this reduces the stale layout
window.

The command basically allows replace brick with src and
dst bricks as same.
Usage:
gluster v reset-brick <volname> <hostname:brick-path> start
This command kills the brick to be reset. Once this command is run,
admin can do other manual operations that they need to do,
like configuring some options for the brick. Once this is done,
resetting the brick can be continued with the following options.
gluster v reset-brick <vname> <hostname:brick> <hostname:brick> commit {force}
Does the job of resetting the brick. 'force' option should be used
when the brick already contains volinfo id.
Problem: On doing a disk-replacement of a brick in a replicate volume
the following 2 scenarios may occur :
a) there is a chance that reads are served from this replaced-disk brick,
which leads to empty reads. b) potential data loss if next writes succeed
only on replaced brick, and heal is done to other bricks from this one.
Solution: After disk-replacement, make sure that reset-brick command is
run for that brick so that pending markers are set for the brick and it
is not chosen as source for reads and heal. But, as of now replace-brick
for the same brick-path is not allowed. In order to fix the above
mentioned problem, same brick-path replace-brick is needed.
With this patch reset-brick commit {force} will be allowed even when
source and destination <hostname:brickpath> are identical as long as
1) destination brick is not alive
2) source and destination brick have the same brick uuid and path.
Also, the destination brick after replace-brick will use the same port
as the source brick.

ipc is used by md-cache to communicate the list of xattrs that
it is caching, to the upcall xlator. Hence implement this in
dht, such that it winds to all the bricks if the ipc op is
GF_IPC_MDC_TARGET_UPCALL. The ips should not fail if any of
the bricks is down, as md-cache will replay the ipc late when
the brick comes back up.

Problem:
In some cases we see that readdir keeps winding to the brick that doesn't have
any blocked locks i.e. first brick. This is leading to the client assuming that
there are no blocking locks on the inode so it won't give away the lock. Other
clients end up blocked on the lock as if the command hung.
Fix:
Proper way to fix this issue is to use infra present in
http://review.gluster.org/14736 This is a stop gap fix where we start taking
inodelks in opendir which goes to all the bricks, this will detect if there is
any contention.

Problem:
When tiering/rebalance does migrations and afr with 2-way replica is in
picture, migration can read stale data if the source brick goes down and writes
to the destination. After this deletion of the file leads to permanent loss of
data after migration.
Fix:
Rebalance/tiering should migrate only when the data is definitely not stale. So
introduce an option in afr called consistent-io which will be enabled in
migration daemons.

cyclic order
When the bricks are brought offline and then online in cyclic
order while writes are in progress on a file, thanks to inode
refresh in write txns, AFR will mostly fail the write attempt
when the only good copy is offline. However, there is still a
remote possibility that the file will run into split-brain if
the brick that has the lone good copy goes offline *after* the
inode refresh but *before* the write txn completes (I call it
in-flight split-brain in the patch for ease of reference),
requiring intervention from admin to resolve the split-brain
before the IO can resume normally on the file. To get around this,
the patch does the following things:
i) retains the dirty xattrs on the file
ii) avoids marking the last of the good copies as bad (or accused)
in case it is the one to go down during the course of a write.
iii) fails that particular write with the appropriate errno.
This way, we still have one good copy left despite the split-brain situation
which when it is back online, will be chosen as source to do the heal.

AFR sets transaction.pre_op[] array even before actually doing the
pre-op on-disk. Therefore, AFR must not only consider the pre_op[] array
but also the failed_subvols[] information before setting the pre_op_done[]
flag. This patch fixes that.

Problem:
When io-threads is enabled on the client side, io-threads destroys the
call-stub in which the loc is stored as soon as the c-stack unwinds.
Because afr is creating a syncop with the address of loc passed in
setxattr by the time syncop tries to access it, io-threads would have
already freed the call-stub. This will lead to crash.
Fix:
Copy loc to frame->local and use it's address.

Return the correct size of the tiered volume in statfs. It should
be the size of the cold tier, not the sum of the hot and cold tier,
because the hot tier is a cache and not an extension of the volume's
capacity. The number of free blocks, etc is the cold tier's capacity
subtracted by the sum of utilization on the hot and cold tiers. Note
if both tiers are part of the same file system this must be accounted
for as well.
The patch also fixes a pre-existing bug in the DHT/tier
translators. If statfs was taken on a file, the code only calculated
free space on the cached subvolume, not all subvolumes in the replica
group. With the fix, this is corrected, except in the case
where quota is used with the deem-statfs option set to "on".

Problem: This issue arises when we do a rolling update
from 3.7.5 to 3.7.9.
For 4+2 volume running 3.7.5, if we update 2 nodes
and after heal completion kill 2 older nodes, this
problem can be seen. After update and killing of
bricks, 2 nodes will return inodelk count key in dict
while other 2 nodes will not have inodelk count in dict.
This is also true for get-link-count.
During dictionary match , ec_dict_compare, this will
lead to mismatch of answers and the file operation
on mount point will fail with IO error.
Solution:
Don't match inode, entry and link count keys while
comparing two dictionaries. However, while combining the
data in ec_dict_combine, go through all the dictionaries
and select the maximum values received in different dicts
for these keys.

Specifically when a directory tree is removed (rm -rf)
while a brick is down, both the directory index and the
name indices of the files and subdirs under it will remain.
Self-heal will need to pick up these and remove them.
Towards this, afr sh will now also crawl indices/entry-changes
and call an rmdir on the dir if the directory index is stale.
On the brick side, rmdir fop has been implemented for index xl,
which would delete the directory index and its contents if present
in a synctask.

Problem: For a read on a file in metadata split-brain:
1.lookup_done resets event_generation to zero.
2. readv is issued, goes to inode refresh due to mismatching event_gen.
3. After refresh is successful, we update event_generation, data and
metdata readable.
3. We then call afr_read_txn_refresh_done() which in turn calls
afr_inode_get_readable() but doesn't check for EIO. So afr_readv_wind
is called with local->readable (which is populated with data_readable),
thus winding the read to a brick.
4. Also, further parallel reads that come directly go to the wind path
because there is no inode_refresh needed.
Fix:
1.For any afr_read_txn(), readable must be an intersection of data and metadata
readable.
2.Check for EIO in afr_read_txn_refresh_done().

dht_selfheal_dir_xattr_cbk
The second parameter's type is call_frame_t *, and we change
it to be type xlator_t *, it is exactly what we need in this function.

When DHT traverses the inode->fd_list, it does that in an unsafe
way that can generate races with fd_unref() called from other threads.
This patch fixes this problem taking the inode->lock and adding a
reference to the fd while it's being used outside of the mutex
protected region.
A minor change in storage/posix has been done to also access the
inode->fd_list in a safe way.

Thanks to Rafi for hinting a while back that this kind of
problem he saw once. I didn't think the theory was valid.
Could have caught it earlier if I had tested his theory.

A race in timer cancellation for delayed unlock could cause a crash
if the cancelling thread fails to cancel the timer because it has
already been fired but not executed, and the callback is scheduled
out of the CPU, delaying it until the thread has released important
resources needed by the callback.
This patch improves the handling of this case to make it robust.

__fd_unref() doesn't do any cleanup, so it cannot be called to release
fd references, specially if it's the last reference.
The code has been changed to avoid a call to this function.
In the previous version we always tried to keep the newest fd in the
ec_lock_t structure. However this is not necessary. We'll always keep
one reference to an open file on the same inode. It's irrelevant if
the reference is new or old.
The function __fd_unref() has also been removed from fd.h to avoid being
used in the future since it's useless as it's defined now.

Problem:
Since commit 8eaa3506ead4f11b81b146a9e56575c79f3aad7b, in replica 3, if a
brick is down and a create fails on the other 2 brick with EDQUOT, we consider
it an unsymmetric error and hence do not do post-op. So the dirty xattr
remains set on the parent dir, leading to conservative merges during heal when
all bricks are up. i.e. a file deleted on the source might re-appear after heal.
Fix:
Consider ENOSPC and EDQUOT as symmetric errors since there is no
possibility of partial inode or entry modification operations possible when
quota is enabled. IOW, if quota reports EDQUOT, the no. of bytes written
(or not written) will be the same on all bricks of the replica.
Likewise, the entry operation (create, mkdir...) will either succeed or
not succeed on all bricks.
