As readdir-ahead can be loaded as a child of dht, dht has to specify
the xattrs it is intrested in, as part of opendir call itself.

In readdirp fop, op_errno is overloaded to indicate the EOD detection.
If op_errno contains ENOENT, then it indicates that there are no
further entries pending read in the directory. Currently NFS uses the
ENOENT to identify the EOD.
Issue:
NFS clients issues a 4K buffer for readdirp, readdir-ahead converts it
to 128K buffer as its reading ahead. If there are 100 entries in the
bricks, 128K can get all 100 and store in readdir-ahead, but only 23
entries that can be fit in 4K will be sent to NFS. Since the whole
100 entries were read from brick, the op_errno is set to ENOENT, and
the op_errno is propagated as is when sent to NFS. Hence NFS client
in reading 23 entries thinks it reached EOD.
Solution:
Do not propogate ENOENT errno, unless all the entries are read
from the readdir ahead buffer.

Backport of https://review.gluster.org/#/c/16657/
Issue:
Any opion is spcified in two places: In the options[] of xlator
itself and glusterd-volume-set.c. The default value of this option
can be specified in both the places. If its specified only in xlator
then the volfile generated will not have the option and default value,
it will be assigned during graph initialization.
With patch [1] the option rda-request-size was changed from INT to SIZET
type, and default was changed from 131072 to 128KB, but was specified
only in the readdir-ahead.c. Thus with this patch alone the volfile
entry for readdir-ahead looks like:
volume patchy-readdir-ahead
type performance/readdir-ahead
subvolumes patchy-read-ahead
end-volume
With patch [2], the default of option rda-request-size was specified
in glusterd-volume-set.c as well(as it was necessary fr parallel readdir).
With this patch the readdir entry in the volfile will look like:
volume patchy-readdir-ahead
type performance/readdir-ahead
option rda-cache-limit 10MB
option rda-request-size 128KB
option parallel-readdir off
subvolumes patchy-read-ahead
end-volume
Now consider the server has both these patches and client doesn't.
Server will generate a volfile with entry:
The old clients which thought the option rda-request-size is of type
INT will now recieve the value 128KB which it willn't understand,
and hence fail the mount.
The issue is seen only with the combination of [1] and [2].
Solution:
Instead of specifying 128KB as default in glusterd we specify 131072
so that the old clients will interpret as INT and new ones as 128KB

dict_get_int can return < 0 when key is not found is a valid case.

Currently STACK_UNWIND is performnd within ctx->lock.
If readdir-ahead is loaded as a child of dht, then there
can be scenarios where the function calling STACK_UNWIND
becomes re-entrant. Its a good practice to not call
STACK_WIND/UNWIND within local mutex's

Issue:
Currently end of directory is identified on obtaining a
readdirp_cbk with op_ret = 0 (i.e. 0 entries fetched in
readdirp). Thus an extra readdirp is required for every
directory just to identify EOD. Consider a case of listing
large number of small directories. The readdirp fops required
are doubled in that case.
Solution:
On reaching the EOD, posix sets the op_errno to ENOENT,
hence along with looking for 'op_ret == 0' we also
look for 'operrno == ENOENT' ehile checking for EOD condition

This patch introduces a new option called "rda-cache-limit", which is
the maximum value the entire readdir-ahead cache can grow into. Since,
readdir-ahead holds a reference to inode through dentries, this patch
also accounts memory stored by various xlators in inode contexts.

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

Problem:
Negative cache feature implementation in md-cache requires xattrs
returned by posix to be intercepted for every call that can possibly
return xattrs. This includes readdirp(). This is crucial to treat
missing keys in cache as a case of negative entry (returns ENODATA)
md-cache puts names of xattrs that it wants to cache in xdata and
passes it down to posix which returns the specified xattrs in the
callback. This is done in lookup() and readdirp(). Hence, a xattr
that is cached can be invalidated during readdirp_cbk too.
This is based on the assumption that readdirp() will always return
all xattrs that md-cache is interested in. However, this is not the
case when readdirp() call is served from readdir-ahead's cache.
readdir-ahead xlator will pre-fetch dentries during opendir_cbk
and readdirp. These internal readdirp() calls made by readdir-ahead
xlator does not set xdata in it's requests. Hence, no xattrs are
fetched and stored in it's internal cache.
This causes metadata loss in gluster-swift. md-cache returns ENODATA
during getxattr() call even though the xattr for that object exists on
the brick. On receiving ENODATA, gluster-swift will create new metadata
and do setxattr(). This results in loss of information stored in
existing xattr.
Fix:
During opendir, md-cache will communicate to readdir-ahead asking it
to store the names of xattrs it's interested in so that readdir-ahead
can fetch those in all subsequent internal readdirp() calls issued by
it. This stored names of xattrs is invalidated/updated on the next
real readdirp() call issued by application. This readdirp() call will
have xdata set correctly by md-cache xlator.

introduced warnings from libtool about the xlator .so names.
According to [1], the -module option must appear in the Makefile.am
file(s); if -module is defined in a macro, e.g. in configure(.ac),
then libtool will not recognize that this is a module and will emit a
warning.

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

posix xlator sends op_errno as ENOENT and op_ret as 0, to indicate readdir has
been completed. readdir-ahead should send that op_errno that it has saved in the
fd context, when it serves the readdir requests. Otherwise some xlators sitting
above performance xlators such as snapview-client, which checks for end of
readdir operation by checking op_ret to 0 and op_errno to ENOENT will not be
able to identify end of readdir.

There has been a misspelled option in the Makefile.am files. The option
is called -avoid-version, and not -avoidversion.
It is not trivial to provide a test-case for this. One way would be to
check generated RPMs with a command like this (output should be empty):
$ rpm -qlp *.rpm | grep -E '/xlator/.+.so.0'

This is a translator to improve the performance of typical,
sequential directory reads (i.e., ls). readdir-ahead begins
preloading the contents of a directory on open and serves readdir
requests from the preloaded content. readdir-ahead is currently
implemented to only handle the single threaded directory read
case.
readdir-ahead is currently disabled by default. It can be enabled
with the following command:
gluster volume set <volname> readdir-ahead on
The following are results of a getdents test on a single brick
volume.
Test info:
- Single VM, gluster client/server.
- Volume mounted with native client using --gid-timeout=2.
- getdents on single directory with 100k 0-byte files.
Test results:
- !readdir-ahead
read 3120080 bytes from offset 0
3 MiB, 4348 ops, 0:00:07.00 (416.590 KiB/sec and 594.4737 ops/sec)
