All: run codespell on the code and fix issues.

2018-07-22T14:40:16+00:00

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!

api: cleanup headers

2018-06-11T13:10:42+00:00

fix inconsistent use in headers of:
  struct glfs and glfs_t
  struct glfs_fd and glfs_fd_t
  struct glfs_object and glfs_object_t

add typedefs to headers for various struct glfs_foos, and use them, e.g.:
  struct glfs_upcall and glfs_upcall_t

fix inconsistent type naming for 'enum glfs_lock_mode_t'. (All other
enum decls are 'enum glfs_foo' not 'enum_glfs_foo_t'), and add
typedefs for all enums, and use them.

style, replace tabs with spaces and follow return value style, i.e.:
  int
  pub_glfs_foo()
instead of:
  int pub_glfs_foo()

Update copyright dates, substantial new work has been done since 2012

gfapi: various broken symbol versions

2018-05-10T15:15:18+00:00

lots of breakage in symbol versions:
  symbols added in 4.1 incorrectly, and
  symbols added in 4.1 but labeled 4.0.0, and
  symbols added in 3.13 incorrectly

Not noticed until someone tried to build 3.13.2 on FreeBSD 11.1,
despite the fact that we build on FreeBSD 10.3 IIRC, somehow the
3.13 errors aren't a build error there.

Note: in rereading the Ulrich Drepper write-up I noticed that when
a symbol version is changed, you are supposed to leave the old
symbol in its original section in addition to adding it to its new
section. Adding back those symbols to their original sections.

gfapi : RECALL_LEASE implementation

2018-05-04T17:12:19+00:00

Right now there are two types of upcalls
* poll method
* registering callback

But callback can be registered per fs and same callback fn shall be used
for any lease recall with object handle as argument as done for cache
invalidation.

TODO: RECALL LEASE for each glfd (for future reference)
 (may be needed fo Samba as they do not deal with
  object handles.

    In case of RECALL_LEASE, we could associate separate
     cbk function for each glfd either by
       - extending pub_glfs_lease to accept new args (recall_cbk_fn, cookie)
       - or by defining new API "glfs_register_recall_cbk_fn (glfd, recall_cbk_fn, cookie)
       . In such cases, flag it and instead of calling below upcall functions, define
        a new one to go through the glfd list and invoke each of theirs recall_cbk_fn.

Plus added following as well
* passed lease id to dict in required arguments
* added flag check in pub_glfs_open

gfapi: Register/Unregister Upcall events' callback

2017-10-31T07:53:50+00:00

Polling continuously for upcall events is not optimal.
Hence new APIs have been added to allow applications to
register and unregister upcall events it is interested in
along with callback function to be invoked in case of any
such upcalls sent by backend server.

@TODO: Make changes in upcall xlator so that events are
sent to only those clients which either registered callbacks
or started polling. Shall be addressed in separate patch.

gfapi: set lkowner in glfd

2017-10-12T10:42:36+00:00

We need a provision to be able to set lkowner (which is
used to distinguish locks maintained by server) in gfapi.
Since the same lk_owner need to be used to be able to
flush the lock while closing the fd, store the lkowner
in the glfd structure itself.

A new API has been added to be able to set lkowner in glfd.

2017-09-01T15:32:55+00:00

glfs_free releases different types of data depends on memory type.
Drop the depends of memory type of memory accounting,
new macro GLFS_CALLOC/GLFS_MALLOC/GLFS_REALLOC/GLFS_FREE are added
to support assign release function dynamically, it adds a separate
memory header named glfs_mem_header for gfapi.
