upstream. Mostly comments, formal item boxing, a sort function,
and const madness reduction.
(slist_new): Removed.
(slist_box, slist_unbox, slist_sort): New.
(SListCompare, SListCallback): Swapped!
(slist_remove, slist_find): Change order of parameters for
orthogonality with slist_foreach. Changed all callers.
* libltdl/lt_dlloader.c (loader_cmp): Renamed to...
(loader_callback): ...this. Return boxed item.
(lt_dlloader_remove): Adjust to new loader_callback semantics;
unbox each removed item before returning.
Remove unused variable.
Remove const from name parameter, since the slist API cannot
guarantee userdata const-ancy for its callback functions.
(lt_dlloader_find): Adjust to new loader_callback semantics; need
to return the contents of the boxed item.
Remove const from name parameter, since the slist API cannot
guarantee userdata const-ancy for its callback functions.
* libltdl/lt_dlloader.h (lt_dlloader_find, lt_dlloader_remove):
Adjust to new constless footprint.
* libltdl/ltdl.c (ltdl_exit): The global `loaders' list is changed
variable `loader' is invalidated. Since some loaders may be
resident modules that cannot be unloaded (though we have none
yet), we must save each `next' address before calling
`lt_dlloader_remove'.
* NEWS: Updated.
* THANKS: Added Ralf.
`loaders' list management into a new SList ADT. In the process,
the API for writing loaders is a little cleaner, so all the
existing loaders were tweaked to take advantage of that:
* libltdl/slist.h, libltdl/slist.c: New files implementing a
generic singly linked list container ADT. The ADT is purely
internal, and none of its API's are visible from an installed
libltdl.
* libltdl/lt_dlloader.h (lt_dlloader): Removed next field again
:-) Renamed to lt_dlvtable for API. Changed all callers.
(lt_dlloader_get): New function to turn an lt_dlloader into its
associated lt_dlvtable.
(lt_dlloader_add): Removed unused data parameter. The caller
data belongs to (and is set by) the loader itself, not the
loader's client. Changed all callers.
(lt_dlloader_name, lt_dlloader_data): Removed. Use
lt_dlloader_get instead!
* libltdl/lt__private.h: Include slist.h.
(lt__alloc_die_callback): Add missing LT_SCOPE to declaration.
(lt_dlhandle_struct): Use lt_dlvtable instead of opaque
lt_dlloader.
* libltdl/ltdl.c (lt_dlexit): Rewritten for the new loader API.
(loaders, lt_dlloader_add, lt_dlloader_remove, lt_dlloader_next,
lt_dlloader_find): Moved from here...
* libltdl/lt_dlloader.c ((loaders, lt_dlloader_add,
lt_dlloader_remove, lt_dlloader_next, lt_dlloader_find): ...to
here. And rewritten in terms of new SList interface.
* libltdl/ltdl.c (lt_dlexit, tryall_dlopen): Rewritten in terms of
new lt_dlloader interface.
* libltdl/Makefile.am (libdlloader_la_SOURCES): Add slist.h and
slist.c. Move lt_dlloader.h from here...
(pkginclude_HEADERS): ...to here.
(libltdl_la_SOURCES): Add lt_dlloader.c and lt_dlloader.h.
