Since glusterd2 don't maintain the xlator option details in code, it
directly reads the xlators options table from `*.so` files. To support
enable and disable of xlator new option added to the option table with
the name same as xlator name itself.
This change will not affect the functionality with glusterd1.

libglusterfs devel package headers are referenced in code using
include semantics for a program, this while it works can be better
especially when dealing with out of tree xlator builds or in
general out of tree devel package usage.
Towards this, the following changes are done,
- moved all devel headers under a glusterfs directory
- Included these headers using system header notation <> in all
code outside of libglusterfs
- Included these headers using own program notation "" within
libglusterfs
This change although big, is just moving around the headers and
making it correct when including these headers from other sources.
This helps us correctly include libglusterfs includes without
namespace conflicts.

It seems there were quite a few unused enums (that in turn
cause unndeeded memory allocation) in some xlators.
I've removed them, hopefully not causing any damage.

Currently, there are possibilities in few places, where a user-controlled
(like filename, program parameter etc) string can be passed as 'fmt' for
printf(), which can lead to segfault, if the user's string contains '%s',
'%d' in it.
While fixing it, makes sense to make the explicit check for such issues
across the codebase, by making the format call properly.

While it may slightly reduce accuracy, I think it's better to
acquire the time outside a lock and then memcpy the value while
under lock.

Post changing the max op-version to 4.2, after release
4.1 branching, the decision was to go with increasing
release numbers. Thus this needs to change to 5.0.
This commit addresses the above change.

Move to GF_MALLOC() instead of GF_CALLOC() when possible
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.
In some cases, also changed allocation size to be sizeof some
struct or type instead of a pointer - easier to read.
In some cases, removed redundant strlen() calls by saving the result
into a variable.
1. Only done for the straightforward cases. There's room for improvement.
2. Please review carefully, especially for string allocation, with the
terminating NULL string.
Only compile-tested!
.. and allocate memory as much as needed.

Don't blindly allocate PATH_MAX, but strlen() the string and allocate
appropriately.
Also, align error messges.

Once invalidated, make sure that only ops incident after invalidation
update the cache. This makes sure that ops before invalidation don't
repopulate cache with stale data. This patch also uses an internal
counter instead of frame->root->unique for keeping track of
generations.

Quick-read by default uses mtime to identify changes to file
data. However there are applications like rsync which explicitly set
mtime making it unreliable for the purpose of identifying change in
file content. Since ctime also changes when content of a file changes
and it cannot be set explicitly, it becomes suitable for identifying
staleness of cached data. This option makes quick-read to prefer ctime
over mtime to validate its cache. However, using ctime can result in
false positives as ctime changes with just attribute changes like
permission without changes to file data. So, use this option only when
mtime is not reliable.
credits to Kotresh Hiremath Ravishankar <khiremat@redhat.com> for
suggestion on using ctime instead of mtime.

with stale data
Thanks to Pranith for the example. Following is the race we are trying
to solve with this patch.
1) We have a file with content 'abc'
2) lookup and writev which replaces 'abc' with 'def' comes. Lookup
fetches abc but yet to update the cache, and then immediately
writev is wound which zeros out the cache. Now lookup_cbk updates
the buffer with 'abc' even though on disk it is 'def'. Now writev
completes and returns to application.
3) application does a readv which will be fetched from quick-read as
'abc'.

qr_content_extract used dict_get to get the value of
the GF_CONTENT_KEY key. dict_get does not ref the data
before returning it so QR could be acting on freed memory
if another thread deletes the key before then.
This patch also fixes a race in dict_get_with_ref.
Fix: Use dict_get_with_ref to retrieve the file contents.

The original situation was as follows:
The function that validates xlator options indicating a size,
xlator_option_validate_sizet(), handles the case when the name
of the option is "cache-size" in a special way.
- Xlator options (things of type volume_option_t) has a
min and max attribute of type double.
- An xlator option is endowed with a gluster specific type (not
C type). An instance of an xlator option goes through a validation
process by a type specific validator function (which are collected
in option.c).
- Validators of numeric types - size being one of them - make use the
min and max attributes to perform a range check, except in one case:
if an option is defined with min = max = 0, then this option will be
exempt of range checking. (Note: the volume_option_t definition
features the following comments along the min, max fields:
double min; /* 0 means no range */
double max; /* 0 means no range */
which is slightly misleading as it lets one to conclude that
zeroing min or max buys exemption from low or high boundary check,
which is not true -- only *both* being zero buys exemption.)
- Besides this, the validator for options of size type,
xlator_option_validate_sizet() special cases options
named "cache-size" so that only min is enforced. (The only consequence
of a value exceeding max is that glusterd logs a warning about it, but
the cli user who makes such a setting gets no feedback on it.)
- This was introduced because a hard coded limit is not useful for
io-cache and quick-read. They rather use a runtime calculated
upper limit. (See changes
I7dd4d8c53051b89a293696abf1ee8dc237e39a20
I9c744b5ace10604d5a814e6218ca0d83c796db80
about the last two points.)
- As an unintended consequence, the upper limit check of
cache-size of write-behind, for which a conventional hard coded limit
is specified, is defeated.
What we do about it:
- Remove the special casing clause for cache-size in
xlator_option_validate_sizet. Thus the general range
check policy (as described above) will apply to
cache-size too.
- To implement a lower bound only check by the validator
for cache-size of io-cache and quick-read, change the
max attribute of these options to INFINITY.
The only behavioral difference is the omission of the warnings
about cache-size of io-cache and quick-read exceeding the former max
values. (They were rather heuristic anyway.)

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

We've been lucky that we haven't had any symbol collisions until now.
Now we have a collision between the snapview-client's svc_lookup() and
libntirpc's svc_lookup() with nfs-ganesha's FSAL_GLUSTER and libgfapi.
As a short term solution all the snapview-client's FOP methods were
changed to static scope. See http://review.gluster.org/11805. This
works in snapview-client because all the FOP methods are defined in
a single source file. This solution doesn't work for other xlators
with FOP methods defined in multiple source files.
To address this we link with libtool's '-export-symbols $symbol-file'
(a wrapper around `ld --version-script ...` --- on linux anyway) and
only export the minimum required symbols from the xlator sharedlib.
N.B. the libtool man page says that the symbol file should be named
foo.sym, thus the rename of *.exports to *.sym. While foo.exports
worked, we will follow the documentation.

Instead of including config.h in each file, and have the additional
config.h included from the compiler commandline (-include option).
When a .c file tests for a certain #define, and config.h was not
included, incorrect assumtions were made. With this change, it can not
happen again.

Commit 4ea5b8d2046b9e0bc7f24cdf1b2e72ab8b462c9e seems to have removed the check
as a part of static analyis fixes but I'm seeing errors in the client log.

- initialize xdata in qr_lookup even if it was NULL from top. This
allows qr to do its job even if lookup originated from fuse-resolve.c
- extend test cases to include 1 second delay and retry
- fix bug while checking condition for cached unwind
qr_readv_cached() unwinds if op_ret > 0. Therefore qr_readv()
must wind to subvol only if !(op_ret > 0) (i.e, op_ret <= 0).
- qr_readv_cached() is using uninitialized @conf pointer. Thanks

Automake provides a separate variable for preprocessor flags
(*_CPPFLAGS). They are already uses in a few places, so make it
consistent and use it everywhere. Note that cflags obtained from
pkg-config often are cppflags, which is why LIBXML2_CFLAGS moves with
into AM_CPPFLAGS, for example.

CFLAGS
libtool will automatically add "-fPIC" to the compiler command line as
needed, so there is no need to specify it separately.
"-shared" is normally a linker flag and has an odd effect when used with
libtool --mode=compile, namely that it inhibits production of static
objects. For that however, using AC_DISABLE_STATIC is a lot simpler.

There are a number of nit-level issues throughout the source with
the use of localtime and ctime. While they apparently aren't causing
too many problems, apart from the one in bz 828058, they ought to be
fixed. Among the "real" problems that are fixed in this patch:
1) general localtime and ctime not MT-SAFE. There's a non-zero chance
that another thread calling localtime (or ctime) will over-write
the static data about to be used in another thread
2) localtime(& <64-bit-type>) or ctime(& <64-bit-type>) generally
not a problem on 64-bit or little-endian 32-bit. But even though
we probably have zero users on big-ending 32-bit platforms, it's
still incorrect.
3) multiple nested calls passed as params. Last one wins, i.e. over-
writes result of prior calls.
4) Inconsistent error handling. Most of these calls are for logging,
tracing, or dumping. I submit that if an error somehow occurs in
the call to localtime or ctime, the log/trace/dump still should
still occur.
5) Appliances should all have their clocks set to UTC, and all log
entries, traces, and dumps should use GMT.
6) fix strtok(), change to strtok_r()
Other things this patch fixes/changes (that aren't bugs per se):
1) Change "%Y-%m-%d %H:%M:%S" and similar to their equivalent shorthand,
e.g. "%F %T"
2) change sizeof(timestr) to sizeof timestr. sizeof is an operator,
not a function. You don't use i +(32), why use sizeof(<var>).
(And yes, you do use parens with sizeof(<type>).)
3) change 'char timestr[256]' to 'char timestr[32]' where appropriate.
Per-thread stack is limited. Time strings are never longer than ~20
characters, so why waste 220+ bytes on the stack?
Things this patch doesn't fix:
1) hodgepodge of %Y-%m-%d %H:%M:%S versus %Y/%m/%d-%H%M%S and other
variations. It's not clear to me whether this ever matters, not to
mention 3rd party log filtering tools may already rely on a
particular format. Still it would be nice to have a single manifest
constant and have every call to localtime/strftime consistently use
the same format.
