debug/error-gen: Use STACK_WIND_TAIL instead of STACK_WIND

2017-04-21T14:36:57+00:00

Also remove unnecessary fop cbks, which are no longer necessary.

1.We don't need to call STACK_WIND if we care nothing in cbk stack, so
  I use STACK_WIND_TAIL instead of STACK_WIND without new a frame
2.Fix several indent problems
3.Fix return value issues in init and reconfigure

Since random is not used for anything cryptographically related,
it is fine to use it in those instances.

build: out-of-tree builds generates files in the wrong directory

2016-09-18T16:34:37+00:00

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

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.

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.

build: do not #include "config.h" in each file

2015-05-29T12:43:17+00:00

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.
