build: export minimum symbols from xlators for correct resolution

2015-12-22T17:15:01+00:00

Revisiting http://review.gluster.org/#/c/11814/, which unintentionally
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.

afr: refresh inode using fstat

2015-12-21T04:04:38+00:00

For fd based operations (fgetxattr, readv etc.) if an inode refresh is
required, do so using fstat instead of lookup. This is because the file
might have been deleted by another client before refresh but posix
mandates that FOPS using already open fds must still succeed.

features/index : Readdirp performance improvement

2015-11-25T03:06:02+00:00

Things done :
Index now maintains two different directories :
1) for pending xattrs (trusted.afr.volname-client-n,
                       trusted.ec.dirty)

2) for on going xattrs (trusted.afr.dirty)

Based on the xattr, index decides the directory
to add/del entry in/from.

core: use syscall wrappers instead of direct syscalls - miscellaneous

2015-10-28T20:38:42+00:00

various xlators and other components are invoking system calls
directly instead of using the libglusterfs/syscall.[ch] wrappers.

If not using the system call wrappers there should be a comment
in the source explaining why the wrapper isn't used.

build: export minimum symbols from xlators for correct resolution

2015-09-24T14:37:42+00:00

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.

all: reduce "inline" usage

2015-09-01T11:55:15+00:00

There are three kinds of inline functions: plain inline, extern inline,
and static inline.  All three have been removed from .c files, except
those in "contrib" which aren't our problem.  Inlines in .h files, which
are overwhelmingly "static inline" already, have generally been left
alone.  Over time we should be able to "lower" these into .c files, but
that has to be done in a case-by-case fashion requiring more manual
effort.  This part was easy to do automatically without (as far as I can
tell) any ill effect.

In the process, several pieces of dead code were flagged by the
compiler, and were removed.
