Please review, it's not always just the comments that were fixed.
I've had to revert of course all calls to creat() that were changed
to create() ...

Only compile-tested!

*.pc: Fix include path in Cflags

2017-11-08T11:10:44+00:00

The include path in glusterfs-api.pc looks like

  -I${includedir}/glusterfs

However, client code will include the glusterfs headers using

  #include 

rather than

  #include 

which makes the "/glusterfs" part entirely unnecessary.

More importantly, on some platforms such as FreeBSD, the header files
for glusterfs will be installed in /usr/local/include, which is *not*
part of the compiler's default include path, so compilation will fail
with something like

  fatal error: 'glusterfs/api/glfs.h' file not found
  #include 
           ^~~~~~~~~~~~~~~~~~~~~~

The fix is to simply drop the extra "/glusterfs". The same change
is applied to other *.pc files as well, althought I haven't actually
tested those.

A test program (gfapi-load-volfile) and the glfsxmp example
application were using the wrong include paths, so they had to be
fixed as well.

libgfapi: adding 'follow' flag to glfs_h_lookupat()

2015-08-24T16:21:51+00:00

Previously glfs_h_lookupat won't follow the symlink, this patch
introduces new flag `follow` which will resolve the same. Applications
linking against the new library will need to use the new glfs_h_lookupat
API call.

In order to stay compatible with existing binaries that use the previous
glfs_h_lookupat() function, the old symbol needs to stay available.

Verification that there are two versions of glfs_h_lookupat:

  $ objdump -T /usr/lib64/libgfapi.so.0 | grep -w glfs_h_lookupat
  0000000000015070 g    DF .text  000000000000021e  GFAPI_3.7.4 glfs_h_lookupat
  0000000000015290 g    DF .text  0000000000000008 (GFAPI_3.4.2) glfs_h_lookupat

Testing with a binary (based on anonymous_fd_read_write.c from ./tests/)
that was linked against the old library:

  $ objdump -T ./lookupat | grep -w glfs_h_lookupat
  0000000000000000      DF *UND*  0000000000000000  GFAPI_3.4.2 glfs_h_lookupat

Enable debugging for 'ld.so' so that we can check that the GFAPI_3.4.2
version of the symbol gets loaded:

  $ export LD_DEBUG_OUTPUT=lookupat.ld.log LD_DEBUG=all
  $ ./lookupat
  $ grep -w glfs_h_lookupat lookupat.ld.log.2543
  2543:     symbol=glfs_h_lookupat;  lookup in file=./lookupat [0]
  2543:     symbol=glfs_h_lookupat;  lookup in file=/lib64/libgfapi.so.0 [0]
  2543:     binding file ./lookupat [0] to /lib64/libgfapi.so.0 [0]: normal symbol `glfs_h_lookupat' [GFAPI_3.4.2]

libgfapi: Fix to compilation failure/warnings for examples/glfsxmp.c

2013-10-16T07:55:50+00:00

The comilation of glfsxmp.c i.e. "make glfsxmp" was failing
with "undefined reference to `clock_gettime'" error.

Fixed all compilation warnings for unused variables and
wrong formart specifier in printf e.g. : "format ‘%d’ expects
argument of type ‘int’, but argument 3 has type ‘__syscall_slong_t’
[-Wformat]"

Also added the compilation steps for glfsxmp.c in the
README file

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.
