445285d9a3 * libltdl/ltdl.c (trim): Return error rather than do bogus 
null pointer arithmetic when parsing a malformed .la file.

ced1775490 * libltdl/lt__strl.c, libltdl/libltdl/lt__strl.h: New files to 
emulate strlcat and strlcpy, which support size-bounded string
copying and concatenation for improved security.

60fbf440cb * m4/ltdl.m4 (LT_LIB_DLLOAD): Define HAVE_LIBDLLOADER if we 
have a dlloader to preload.

11eb79b689 The ltdl.h header is the published interface to libltdl, and 
is thus not installed to $prefix/include/libltdl.  It has always
been used with `#include <ltdl.h>', so move just that one file
back to where it was before:

* libltdl/libltdl/ltdl.h: Moved from here...
* libltdl/ltdl.h: ...to here.
* libltdl/Makefile.am: Adjust.
 2004-11-23 16:08:56 +00:00
Peter O'Gorman
c3f040fa18 Do not require that libtoolize --ltdl=/some/path end in libltdl. Move 
most libltdl headers to libtldl/libltdl to allow
#include <libltdl/ltdl.h> to always work.

* libltdl/Makefile.am, libltdl/loaders/Makefile.am: Look for includes
in the new location.
* libltdl/libltdl/lt__alloc.h, libltdl/libltdl/lt__dirent.h,
libltdl/libltdl/lt__glibc.h, libltdl/libltdl/lt__private.h,

9bc5390549 * libltdl/lt__alloc.c (lt__memdup): Allocation can fail, so we 
need to guard against null pointer dereference here.

 2004-10-01 10:24:18 +00:00

Ralf Wildenhues

case the name given to lt_dlopen contains no extension.

8286085803 * libltdl/lt_dlloader.c (lt_dlloader_remove), libltdl/ltdl.c

7955f590bb * libltdl/loaders/loadlibrary.c: Compilation fixes (originally 
from Gary V. Vaughan) to compile under MinGW.
* config/mkstamp: Translate input data so that it is assured to
use the Unix line terminations. This is necessary under Windows if
the files are checked out with CR/NL line terminations. A
side-effect of this change is that input must always be from
stdin. Previously a filename argument was accepted as well.

cae83b341b * libltdl/slist.c, libltdl/slist.h: Merge in changes from latest 
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.

Gary V. Vaughan
53f09b2d98 Don't use C99 flexible array types as we want to be C89 
compatible.  Instead, revert to the old way of doing things with
an array of symbol name vs. address, and adding the originator as
the first symbol but with a NULL address:

* config/ltmain.in (func_extract_dlsyms): Store originator as a
NULL address symbol.
* libltdl/ltdl.h (lt_dlsymbol): Removed.
(lt_dlsymlist): Remove originator field.
(LTDL_SET_PRELOADED_SYMBOLS): Adjust.
* libltdl/loaders/preopen.c (vm_open, lt_dlpreload_open): Adjust
for new types.
(vm_sym): Skip the new originator symbol when scanning symbol
names.
* m4/libtool.m4 (_LT_CMD_GLOBAL_SYMBOLS): Adjust preloaded symbols
test file to match.

5da74960c2 * libltdl/lt_dlloader.c (lt_dlloader_remove): Since the return

caller on return.

388b7626dc The Grand Renaming. In preparation for libtool-2.0, move all of 
the many and varied m4 symbols accumulated by libtool over the
years, considering also that modern autoconf can detect unexpanded
macros even without AC in the macro name:

* bootstrap: Remove libltdl/config.h from previous releases.
* m4/libtool.m4, m4/ltdl.m4, doc/libtool.texi: Basically, run a
giant sed transformation like this:
