* Remove the options to load old symbol. * keep only 'xlator_api' symbol from being exported using xlator.sym * add xlator_api to all the xlators where its missing NOTE: This covers all the xlators which has at least a test case to validate its loading. If there is a translator, which doesn't have any test, then we should probably remove that from codebase. fixes: #164 Change-Id: Ibcdc8c9844cda6b4463d907a15813745d14c1ebb Signed-off-by: Amar Tumballi <amarts@redhat.com>
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.

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 Change-Id: Iba6ab96b2d0a17c5a7e9f92233993b318858b62e BUG: 1330604 Signed-off-by: Kaleb S KEITHLEY <kkeithle@redhat.com> Reviewed-on: http://review.gluster.org/14085 Tested-by: Niels de Vos <ndevos@redhat.com> Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Niels de Vos <ndevos@redhat.com>
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.

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.

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. Signed-off-by: Kaleb S.
