libgfapi: To support set_volfile-server-transport type "unix"

2015-12-02T09:19:54+00:00

This patch helps libgfapi to get the volfile using Unix domain socket.
run the attachment file in the bug to test.
The patch checks if the glfs_set_volfile_server transport is of type "unix",
If It is then uses rpc_transport_unix_options_build to get the volfile.

gfapi: add glfs_h_acl_set() and glfs_h_acl_get()

2015-03-18T17:39:03+00:00

These two functions add support for POSIX ACLs through the GFAPI-handle
interface.

The initial infrastructure for POSIX ACLs based on libacl has been added
with the required changes to the POSIX xlator:

NetBSD does not support POSIX ACLs, so using any of the functions should
return ENOTSUP.

api: versioned symbols in libgfapi.so for compatibility

2015-01-12T17:16:08+00:00

Use versioned symbols to keep libgfapi at libgfapi.so.0.0.0

Revisited to address broken build on Mac OS X

See http://review.gluster.org/9036

Rebased to include http://review.gluster.org/#/c/9376/ (glfs_resolve())
but note that gerrit's "Rebase Change" couldn't do it.

N.B. noticed that glfs_get_volumeid() decl in glfs.h was missing
the __THROW, added it.

On systems using ELF and the GNU toolchain, symbol versions are created
with a .symver asm operand in the .c source file. Clang is claimed to
be compatible with gcc, so we'll pretend for now that this also works
with clang.

On Mac OS X, aliases are created with __asm "magic" in the .h header
file. In the normal case, when both the decl and defn match, that's
all that's needed. In our case though the decl and defn don't match ---
we have, e.g. a defn such as 'int glfs_foo(...)' and the corresponding
decl is 'int pub_glfs_foo(...)'. To make this work we create the necessary
aliases in the library at link time with the -alias_list link option.

Note that this results in there being pairs of symbols in the .dylib,
e.g. _pub_glfs_foo and _glfs_foo$GFAPI_3.4.0. We could use another
link option, -unexported_symbols_list to elide the _pub_glfs_* symbols.
(And we probably should.)

Linux symbol versioning was essentially copied from Solaris; in general
I would expect this to "just work" on Solaris, but until someone tries
we don't really know.

api: versioned symbols in libgfapi.so for compatibility

2014-11-07T08:23:34+00:00

Use versioned symbols to keep libgfapi at libgfapi.so.0.0.0

Some nits uncovered:

+ there are a couple functions declared that do not have an
  associated definition, e.g. glfs_truncate(), glfs_caller_specific_init()

+ there are seven private/internal functions used by heal/src/glfsheal
  and the gfapi master xlator (glfs-master.c): glfs_loc_touchup(),
  glfs_active_subvol(), and glfs_subvol_done(), glfs_init_done(),
  glfs_resolve_at(), glfs_free_from_ctx(), and glfs_new_from_ctx();
  which are not declared in glfs.h;

+ for this initial pass at versioned symbols, we use the earliest version
  of all public symbols, i.e. those for which there are declarations in
  glfs.h or glfs-handles.h.
  Further investigation as we do backports to 3.6, 3.4, and 3.4
  will be required to determine if older implementations need to
  be preserved (forward ported) and their associated alias(es) and
  symbol version(s) defined.

FWIW, we should consider linking all of our libraries with a map, it'll
result in a cleaner ABI. Perhaps something for an intern to do or a
Google Summer of Code project.

build: Start using library versioning for various libraries

2014-01-18T16:51:14+00:00

According to libtool three individual numbers stand for
CURRENT:REVISION:AGE, or C:R:A for short. The libtool
script typically tacks these three numbers onto the end
of the name of the .so file it creates. The formula for
calculating the file numbers on Linux and Solaris is

   /path/to/library/.(C - A).(A).(R)

As you release new versions of your library, you will
update the library's C:R:A. Although the rules for changing
these version numbers can quickly become confusing, a few
simple tips should help keep you on track. The libtool
documentation goes into greater depth.

In essence, every time you make a change to the library and
release it, the C:R:A should change. A new library should start
with 0:0:0. Each time you change the public interface
(i.e., your installed header files), you should increment the
CURRENT number. This is called your interface number. The main
use of this interface number is to tag successive revisions
of your API.

The AGE number is how many consecutive versions of the API the
current implementation supports. Thus if the CURRENT library
API is the sixth published version of the interface and it is
also binary compatible with the fourth and fifth versions
(i.e., the last two), the C:R:A might be 6:0:2. When you break
binary compatibility, you need to set AGE to 0 and of course
increment CURRENT.

The REVISION marks a change in the source code of the library
that doesn't affect the interface-for example, a minor bug fix.
Anytime you increment CURRENT, you should set REVISION back to 0.

gfapi: object handle based API extensions

2013-10-11T19:16:46+00:00

There is an ongoing effort to integrate NFS Ganesha (
https://github.com/nfs-ganesha/nfs-ganesha/wiki ) with GlusterFS as one of
the file system back ends.

Towards this we need extensions to gfapi that can handle object based
operations. Meaning, instead of using full paths or relative paths from
cwd, it is required that we can work with APIs, like the *at POSIX
variants, to be able to create, lookup, open etc. files and directories.
Hence the objects are the files or directories themselves and we give out
handles to these objects that can be used for further operations.

This code drop is an initial implementation of the proposed APIs.

The new APIs are implemented as glfs_h_XXX variants in the file
glfs-handleops.c to mirror glfs-fops.c style. The code leverages holding
onto inode references and doling these out as opaque/cookie type objects to
the callers, to enable them to be used as handles in other operations.

An fd based approach was considered, but due to the extra footprint that
the fd structure and its counterparts would incur, this was dropped to take
the approach of holding inode references themselves.

Tested by extending glfsxmp.c to invoke and exercise the added APIs, and
further tested with a reference integration of the same as an FSAL with NFS
Ganesha.

api/Makefile: link api.so against libgfapi (and dependencies)

2013-05-29T12:27:33+00:00

Samba opens vfs_gluster.so with dlopen(..,RTLD_LOCAL). This makes
the symobls in the shared module and the library it exclusively
links against (specifically gfapi) not resolvable from the .so
files which are opened in turn within (like xlator .so files)
unless explicitly linked against the dependent libraries.

This is not otherwise required in case of glusterfsd as the main
executable symbols are always available for resolution from
dlopen()'ed shared objects, making Samba's vfs_glusterfs
requirement unique, but luckily not incompatible.
