* libglusterfs: Move devel headers under glusterfs directoryShyamsundarR2018-12-051-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | 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!

* refcount: correct the return value of GF_REF_PUT()Niels de Vos2017-03-211-2/+6
| | | | | | | | | | | | | | | | | It is documented that GF_REF_PUT() returns a 0 in case the call resulted in free'ing the structure. However the implementations did not have a return value, so nothing can actually use it.

* refcount: return pointer to the structure instead of a counterNiels de Vos2016-12-111-14/+7
| | | | | | | | | | | | | | | | There are no real users of the counter. It was thought of a handy tool to track and debug refcounting, but it is not used at all. Some parts of the code would benefit from a pointer getting returned instead.

* core: add "gf_ref_t" for common refcounting structuresNiels de Vos2015-06-201-0/+112
Checks for compiler supported atomic operations comes from client_t.h. An example usage of this change can be found in adding reference counting to "struct auth_cache_entry" in http://review.gluster.org/11023 Basic usage looks like this: #include "refcount.h" struct my_struct { GF_REF_DECL; ... /* more members */ } void my_destructor (void *data) { struct my_struct *my_ptr = (struct my_struct *) data; ... /* do some more cleanups */ GF_FREE (my_ptr); } void init_ptr (struct parent *parent) { struct my_struct *my_ptr = malloc (sizeof (struct my_struct)); GF_REF_INIT (my_ptr, my_destructor); /* refcount is set to 1 */ ... /* my_ptr probably gets added to some parent structure */ parent_add_ptr (parent, my_ptr); } void do_something (struct parent *parent) { struct my_struct *my_ptr = NULL; /* likely need to lock parent, depends on its access pattern */ my_ptr = parent_remove_first_ptr (parent); /* unlock parent */ ... /* do something */ GF_REF_PUT (my_ptr); /* calls my_destructor on refcount = 0 */ } URL: http://thread.gmane.org/gmane.comp.file-systems.gluster.devel/11202 Change-Id: Idb98a5861a44c31676108ed8876db12c320912ef BUG: 1228157 Signed-off-by: Niels de Vos <ndevos@redhat.com> Reviewed-on: http://review.gluster.org/11022 Reviewed-by: Xavier Hernandez <xhernandez@datalab.es> Reviewed-by: Krishnan Parthasarathi <kparthas@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Tested-by: NetBSD Build System <jenkins@build.gluster.org>
