For both Virt and block workloads the file is opened multiple times
leading to dynamically setting eager-lock to off for the workload.
Instead of depending on the number-of-open-fds, if we change the
logic to depend on number of inodelks, then it will give better
performance than the earlier logic. When there is an eager-lock
and number of inodelks is more than 1 we know that there is a
conflicting lock, so depend on that information to decide whether
to keep the current transaction go through delayed-post-op or not.
Locks xlator doesn't have implementation to query number of locks in
fxattrop in releases older than 3.10 so to keep things backward
compatible in 3.12, data transactions will use new logic where as
fxattrop transactions will use old logic. I am planning to send one
more patch which makes metadata domain locks also depend on
inodelk-count

With root-squash on, all root credentials are converted to a
random uid, gid(65535). And ideally this does not carry the necessary
permission bits to carry out the operation. But posix-acl will allow
operations from this inode as long as its ctx has the ngroup information
and ngroup has the owner group information.
The problem we ran into recently was somehow posix-acl xlator did not
cache the ngroup info and some of the dht internal fops(layout setxattr)
failed with root-squash enabled.
DHT internal fops now use a negative pid to pretend that the operation
is from an internal client so posix-acl allows them to pass

With this change when SHD starts the index crawl it requests
all the clients to release the AFR_TA_DOM_NOTIFY lock so that
clients will know the in memory state is no more valid and
any new operations needs to query the thin-arbiter if required.
When SHD completes healing all the files without any failure, it
will again take the AFR_TA_DOM_NOTIFY lock and gets the xattrs on
TA to see whether there are any new failures happened by that time.
If there are new failures marked on TA, SHD will start the crawl
immediately to heal those failures as well. If there are no new
failures, then SHD will take the AFR_TA_DOM_MODIFY lock and unsets
the xattrs on TA, so that both the data bricks will be considered
as good there after.

Problem:
Currently in glusterd code uses sync_lock/sync_unlock to update blockers
counter which could add delays to the overall transaction phase
escpecially when there's a batch of volume stop operations processed by
glusterd in brick multiplexing mode.
Solution: Use GF_ATOMIC to update blocker counter to ensure unnecessary
context switching can be avoided.

This patch fixes CID 1210979, 1214614, 1292650, 1357874, 1382404.
1. overflowed or a truncated value : call to sys_read has been reduced
to 'sizeof(buf) -1' and after operation buf is properly terminated.
2. tainted_data_argument : truncation due to cast operation on operand :
resulted form call to strtol: chaged data type from pid_t to long.
3. tainted_data_argument : call to fgets is reduced by 2 to make space
for the '\n' and '\0'.

Problem:
When eager-lock is disabled because of multiple-fds opened and app
writes come on conflicting regions, the number of locks grows very
fast leading to all the CPU being spent just in locking and unlocking
by traversing huge queues in locks xlator for granting locks.
Fix:
Reduce the number of locks in transit by bundling the writes in the
same lock and disable delayed piggy-pack when we learn that multiple
fds are open on the file. This will reduce the size of queues in the
locks xlator. This also reduces the number of network calls like
inodelk/fxattrop.
Please note that this problem can still happen if eager-lock is
disabled as the writes will not be bundled in the same lock.

Also fixes the issue caused due to not converting back the fn function
to after getting its address. We wanted the value of the field, not
the address of the pt_fop field.
With this patch, DHT will always be started in pass-through
mode if the number of subvols is just 1.
Fixes some tests to make sure DHT is in full config (ie, subvols > 1).
- increased timeout of brick-mux test as it was bordering on 300 seconds.
- Also change the volume type to supported 'replica 3' from 'replica 2'.
- also no DHT tests should assume presence of DHT when there is
just 1 brick in volume

No default value was specified for `export-statfs-size` in posix
option table. Glusterd2 sets default value as `off` since the
option type is `bool`. Posix treats `export-statfs-size=on` if
not specified in volfile(That means default value is `on`)
This patch sets default value as `on`

1. '--ignore-mising-args' option for rsync is not
being used even though the rsync version is
greater than 3.1.0. Fixed the same.
2. '--existing' option for rsync is also not being
used. Fixed the same.
3. geo-rep config fails to set rsync-options as the
value contains '--'. Interestingly, python argsparse
treats the value with '--' (e.g., --ignore-missing-args)
as option. But when passed with something like
--value=--ignore-missing-args, it succeeds. Fixed the
same.

Problem: With commit cb0339f92, we are using a separate syntask
for restart_bricks. There can be a situation where two threads
are accessing the same volinfo structure at the same time and
updating volinfo structure. This can lead volinfo to have
inconsistent values and assertion failures because of unexpected
values.
Solution: While updating the volinfo structure, acquire a
store_volinfo_lock, and release the lock only when the thread
completed its critical section part.

While attempting to build a (pre-)5.0 of glusterfs on Ubuntu
bionic and cosmic, it became apparent that there are some gremlins
hiding in the combination of the xlator export-symbols, the newish
addition of -Wl,--no-undefined, and the new switch to libuuid from
the old contrib/uuid.
Note: even though Fedora 28 (and later) and Ubuntu bionic (and
later) have the same nominal version of libtool, the Fedora version
appears to do a better job of recursing through dependencies to
determine the libraries to link with.
Examination of the build logs showed that despite appearing to work
on Fedora, not all xlators and shared libs were linked with -Wl,
--no-undefined, and -luuid. And in the case of the gnfs xlator, it
was not only not linked with -Wl,--no-undefined but alsos not linked
with -lgfxdr and -lgfrpc.
Added GF_XLATOR_LDFLAGS, similar to GF_XLATOR_DEFAULT_LDFLAGS.
GF_XLATOR_DEFAULT_LDFLAGS is for xlators that export/expose the
default or common set of symbols. GF_XLATOR_LDFLAGS is for those
remaining xlators that export/expose non-default symbols, e.g. dht
and glupy. This removes the need in the future to add things like
$(UUID_LIBS) to every xlator's Makefile.am. Just add it to
GF_XLATOR_LDFLAGS and GF_XLATOR_DEFAULT_LDFLAGS in configure.ac
and you're done.
This patch was tested on Fedora 28 (build, rpmbuild), Fedora
Rawhide/30 (rpmbuild), RHEL8 (rpmbuild), CentOS7 (rpmbuild), Fedora
koji --scratch build for f30/rawhide, and a Launchpad build for
Ubuntu cosmic/18.10.

Surprisingly, there is not set_boolean() as there is a get_boolean()
In fact, it is stored as an INT dictionary type.
In some occasions it was stored using a string, and this caused
errors such as:
key gfproxy-server, integer type asked, has string type [Invalid argument]
I've fixed what I saw in some logs, I'm sure there are more.
The CORRECT fix is to create a boolean set and use it, but this
requires a bit more work. I'll see if I can do it later on.
Only compile-tested!

* One #!/usr/bin/env python and three #!/usr/bin/python were overlooked
in all the other python fixups. Ugh.
* Two new python files missed the memo about #!/usr/bin/python3.
* One #!/usr/bin/env bash.
Various distribution packaging policies have strong wording about
the use of #!/usr/bin/env ...
Note: this patch does not change the use of #!/usr/bin/env bash in
the two files extras/{clang-checker.sh,check_goto.pl} as these are
not included in any packages. (Although I'm not actually sure why
anyone would ever use '/usr/bin/env {sh,bash}' as I'm not aware of
any version-specific differences like there are with, e.g., python.)
* One #!/usr/bin/bash.
On Fedora and CentOS > 6, /bin is a symlink to /usr/bin, so it
makes little difference. But Debian & Ubuntu still have separate
/bin and /usr/bin; and sh and bash are in /bin, not /usr/bin.
(Historically, in BSD and SYSV Unix it was /bin/sh.)
Note: Fedora and CentOS package build runs a script that converts
all /bin/sh and /bin/bash to /usr/bin/sh and /usr/bin/bash.

wb_fulfill_request
The bug is very similar to bz 1379655 and the fix too very similar to
commit a8b2a981881221925bb5edfe7bb65b25ad855c04.
Before this patch, a request is removed from wip queue only when ref
count of request hits 0. Though, wb_fulfill_request does an unref,
it need not be the last unref and hence the request may survive in
wip queue till the last unref. Let,
T1: the time at which wb_fulfill_request is invoked
T2: the time at which last unref is done on request
Let's consider a case of T2 > T1. In the time window between T1 and
T2, any other request (waiter) conflicting with request in liability
queue (blocker - basically a write which has been lied) is blocked
from winding. If T2 happens to be when wb_do_unwinds is invoked, no
further processing of request list happens and "waiter" would get
blocked forever. An example imaginary sequence of events is given
below:
1. A write request w1 is picked up for winding in __wb_pick_winds
and w1 is moved to wip queue. Let's call this
invocation of wb_process_queue by wb_writev as PQ1. Note w1 is not
unwound.
2. A dependent write (w2) hits write-behind and is unwound followed by
a flush (f1) request. Since the liability queue
of inode is not empty, w2 and f1 are not picked for unwinding. Let's call
the invocation of wb_process_queue by wb_flush as PQ2. Note that
invocation of wb_process_queue by w2 doesn't wind w2 instead
unwinds it after which we hit PQ2
3. PQ2 continues and picks w1 for fulfilling and invokes
wb_fulfill. As part of successful wb_fulfill_cbk,
wb_fulfill_request (w1) is invoked. But, w1 is not freed (and hence
not removed from wip queue) as w1 is not unwound _yet_ and a
ref remains (PQ1 has not invoked wb_do_unwinds _yet_).
4. wb_fulfill_cbk (triggered by PQ2) invokes a wb_process_queue (let's
say PQ3). w2 is not picked up for winding in PQ3 as w1 is still in wip
queue. At this time, PQ2 and PQ3 are complete.
5. PQ1 continues, unwinds w1 and does last unref on w1 and w1 is freed
(and removed from wip queue). Since PQ1 didn't invoke
wb_fulfill on any other write requests, there won't be any future
codepaths that would invoke wb_process_queue and w2 is stuck
forever. This will prevent f2 too and hence close syscall is hung
With this fix, w1 is removed from liability queue in step 3 above and
PQ3 winds w2 in step 4 (as there are no requests conflicting with w2
in liability queue during execution of PQ3). Once w2 is complete, f1
is resumed.

Using the dht_filter_loc_subvol_key to create
files on specific subvols did not create a linkto
file. This can make the file inaccessible as
lookup-optimize is now enabled by default.

GF_CALLOC() when
It doesn't make sense to calloc (allocate and clear) memory
when the code right away fills that memory with data.
It may be optimized by the compiler, or have a microscopic
performance improvement.
Please review carefully, especially for string allocation, with the
terminating NULL string.
Only compile-tested!

Commit 09198e203e has introduced a new coverity with ID 1395635.
keylen variable is assigned to some value but stored value is
overwritten before it is used. This patch addresses the issue.

In a previous patch (https://review.gluster.org/20769) we've
added the key length to be passed to dict_* funcs, to remove the need
to strlen() it. This patch moves some xlators to use it.
- It also adds dict_get_int32n which was missing.
- It also reduces the size of some key variables.
They were set to 1024b or PATH_MAX, where sometimes 64 bytes were
really enough.
Please review carefully:
1. That I did not reduce some the size of the key variables too much.
2. That I did not mix up some keys.
Compile-tested only!

strncpy may not be very efficient for short strings copied into
a large buffer: If the length of src is less than n,
strncpy() writes additional null bytes to dest to ensure
that a total of n bytes are written.
Instead, use snprintf(). Try to ensure output is not
truncated.
Also:
- save the result of strlen() and re-use it when possible.
- move from strlen to SLEN (sizeof() ) for const strings.
Compile-tested only!

The earlier implementation required the file to already exist
when trying to get the hashed subvol. The reworked implementation
allows a user to get the hashed subvol for any filename, whether
it exists or not.
Usage: getfattr -n "dht.file.hashed-subvol.<filename>" <parent dir>
Eg:To get the hashed subvol for file-1 inside dir-1
getfattr -n "dht.file.hashed-subvol.file-1" /mnt/gluster/dir1

If a fop has succeeded on all the bricks and trying to release
the lock, there is no need to update the version for the
file/entry. All it will do is to increase the version from
x to x+1 on all the bricks.
If this update (x to x+1) fails on some brick, this will indicate
that the entry is unhealthy while in realty everything is fine
with the entry.
Avoiding this update will help to not to send one xattrop
at the end of the fops. Which will decrease the chances
of entries being in unhealthy state and also improve the
performance.
