gfapi: 'glfs_h_creat_open' - new API to create handle and open fd

2019-09-26T14:51:19+00:00

Right now we have two separate APIs, one
- 'glfs_h_creat_handle' to create handle & another
- 'glfs_h_open' to create a glfd to return to application

Having two separate routines can result in access errors
while trying to create and write into a read-only file.

Since a fd is opened even during file/directory creation,
introducing a new API to make these two operations atomic i.e,
which can create both handle & fd and pass them to application

This is backport of below mainline patch -

- bz#1753569

gfapi : making glfs_setattr/glfs_fsetattr as public

2019-01-16T06:24:45+00:00

Initially glfs_fsetattr and glfs_setattr, both functions accepted iatt as arguements
but now they accept stat and later in the function the stat is being converted to iatt
so that it can be passed to syncop_fsetattr/syncop_setattr.

libglusterfs: Move devel headers under glusterfs directory

2018-12-05T21:47:04+00:00

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.

gfapi: Send fop_attr dict as part of syncop_open

2018-11-17T09:16:13+00:00

Leaseid (stored in thread locals) is sent to server via xdata.
This dict variable is set but not passed as argument in glfs_h_open().
Fixed the same.

gfapi: Use inode_forget in case of unlink/rename objects

2018-08-21T04:49:46+00:00

After unlink/rename, the nonexistent inode should be remove from inode table,
that's better than put to lru list.

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 : 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
