`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.
* libltdl/lt_dlloader.h (lt_dlloader): Add next field.
* libltdl/ltdl.c (lt_user_dlloader): Remove entirely. Change all
callers to use lt_dlloader instead. Add a compatibility macro.
(lt_dlloader_add): Remove copy and allocate stage, just hook
directly into the loaders list.
than my move of the module field into lt_dlinfo:
* libltdl/ltdl.c (lt_caller_data, lt_dlhandle_struct): Move from
here...
* libltdl/lt__private.h (lt_caller_data, lt_dlhandle_struct):
...to here. And put the module field back here...
* libltdl/ltdl.h (lt_dlinfo): ...instead of here.
* libltdl/loaders/loadlibrary.c (vm_open): Adjust.
operation of libtool (neither would work alone). First, there is
a new feature that allows libraries to preopen modules. This
entails a backwards incompatible change to the libltdl API for
separating out the preloaded symbol lists by owner. Second, in
the tradition of "eating our own dogfood", libltdl now preloads
its own dlloaders. The internal API for dlloaders has also had to
change in a backwards incompatible way in support of the new
library preloading feature. If you don't use preloaded libraries,
you needn't change your project sources, though you will need to
recompile against the new libltdl. The API changes are mostly
confined to dlloaders, so you probably needn't worry about those
(unless you have written a custom loader that you want libltdl to
use):
* configure.ac (AC_CONFIG_FILES): Add libltdl/loaders/Makefile.
* libltdl/configure.ac (AC_CONFIG_FILES): Add loaders/Makefile.
* libltdl/loaders: New directory for module loaders, to simplify
Makefile rules, and to give the loaders themselves names that are
unique in the first few characters.
* libtoolize.in (func_copy_all_files): Copy recursively to pick up
the loaders directory contents.
* libltdl/loaders/Makefile.am: New file. Move module building
rules to here...
* libltdl/Makefile.am: ...from here.
(VERSION_INFO): Bumped version info to signify interface changes.
(libltdl_la_CPPFLAGS, libltdlc_la_CPPFLAGS): Set LTDLOPEN
appropriately for each library.
* libltdl/loader-dld_link.c, libltdl/loader-dlopen.c,
libltdl/loader-dyld.c, libltdl/loader-load_add_on.c,
libltdl/loader-loadlibrary.c libltdl/loader-preopen.c,
libltdl/loader-shl_load.c: Moved from here...
* libltdl/loaders/dld_link.c, libltdl/loaders/dlopen.c,
libltdl/loaders/dyld.c, libltdl/loaders/load_add_on.c,
libltdl/loaders/loadlibrary.c libltdl/loaders/preopen.c,
libltdl/loaders/shl_load.c: ...to here.
(get_vtable): New entry function for each.
* libltdl/loaders/preopen.c (lt_dlsymlists_t): Replaced by...
(symlist_chain): ...a new structure which maps lists of preloaded
symbols from the object that loads them.
(lt_dlpreload_open): New function to automatically open all
preloaded modules belonging to a named object (ORIGINATOR).
* libltdl/lt__alloc.c (lt__zalloc): New function to return a block
of zeroed out new memory.
* libltdl/lt__alloc.h (lt__zalloc): Prototype it.
* libltdl/lt__private.h (lt__alloc_die_callback): Add missing
prototype.
(lt__error_strings): Make this opaque to callers.
* libltdl/lt_error.c (lt__error_strings): Move the implementation
to here.
* libltdl/lt_dlloader.h (lt_user_dlloader): Add extra fields to
make originator focused preloading possible. *BREAKS BACKWARDS
COMPATIBILITY*
(lt_dlloader_add): Take advantage of new fields to simplify
paramater list.
* libltdl/lt_system.h (LT_STR): New ANSI stringification macro.
(LT_CONC): Fix it to work from within macros.
* libltdl/ltdl.c (loader_init, loader_init_callback): Simplify
dlloader loading.
(get_vtable, preloaded_symbols): Point these at the preopen.c
symbols to bootstrap the loader chain.
(lt_dlinit): Load the preopen dlloader manually, and then use it
to load any other preloaded dlloaders.
(lt_dlloader_add): Simplify parameter list. Populate new
fields. Chain new loaders according to priority field.
* libltdl/ltdl.h (lt_dlsymlist): Add a new originator field.
(lt_dlpreload_callback_func): Type of a callback for automatic
lt_dlpreload_open loading.
(LTDL_SET_PRELOADED_SYMBOLS): Adjust to hook into preloaded
symbols from the "@PROGRAM@" originator.
* tests/demo/dlmain.c (main): Use mangled preloaded_symbols symbol.
* tests/pdemo/longer_file_name_dlmain.c (main): Ditto.
* ltmain.in: Don't spew spurious warnings when dlopening and
dlpreopening modules.
(func_generate_dlsyms): Factored out from multiple copies in the
rest of the code. Generate originator keyed symbol lists.
(func_extract_archives): Also factored. Extract the contents of
convenience archives for linking with dependent libraries when
--whole-archive is not available.
[darwin]: Don't try to link $old_library unless it exists, and
$lib is a bundle.
* m4/ltdl.m4 (AC_LTDL_DLLIB): Check for all possible dynamic
loading libraries/apis rather that stopping when an acceptable one
is discovered.
(LT_DLLOADERS): New variable for holding dlloaders that can be
preloaded.
* doc/libtool.texi: Document interface changes.
* NEWS: Updated.
* libltdl/ltdl.c (lt_dlhandle_struct): ...from here. Changed all
callers.
* libltdl/loader-loadlibrary.c (sys_wll_open): Use new inteface to
scan loaded handle->info.module fields for previously loaded
modules.
* doc/libtool.texi (User defined module data): Document changes to
the interface.
* NEWS: Updated.

code, so it is okay to do it during bootstrap, but other projects
need to treat libltdl as a configurable subproject to keep their
respective LIBOBJS separate:
* libltdl/configure.ac: New file, based on configure.ac.
* libltdl/Makefile.am (AC_LOCAL_AMFLAGS): Use our own m4
directory.
(ltdldata_DATA): List *all* the files that libtoolize --ltdl will

* libltdl/argz.c (HAVE_CONFIG_H): Set it up how ltdl likes it when
used by another client.
* m4/argz.m4: New file.
(gl_FUNC_ARGZ): Try to find an error_t definition, and a system
argz.h.
* m4/ltdl.m4: Use it.
(AC_LTDL_FUNC_ARGZ): Removed.
* libltdl/lt__glibc.h: #include <argz.h> to pick up either the
system argz.h or our libltdl/argz.h if necessary.
* libltdl/Makefile.am (libltdl_la_SOURCES): Move argz.h from

(ltdldata_DATA): ...here. Along with argz.c.
(argz.h): Generate from argz_.h if the system file is missing.

Applications should assume that the native dlopen is NOT
thread-safe, and take care of locking themselves. All application
calls into libltdl should thus be protected by the caller.
* libltdl/lt_mutex.c, libltdl/lt_mutex.h: Removed.
* libltdl/Makefile.am (pkginclude_HEADERS): Removed lt_mutex.h.
(libltdl_la_SOURCES): Removed lt_mutex.c and lt_mutex.h.

$Revision: 1.1470 $ $Date: 2004/04/08 12:01:57 $
There was no clean separation of abstraction layers in libltdl.
The first step in fixing this is to factor out the memory
management abstraction, making a start on removing promiscuity
from the underlying portability layer:
* doc/libtool.texi (Libltdl interface): Remove lt_dlmalloc,
lt_dlrealloc and lt_dlfree references. The memory management
layer used by libltdl is now private.
* libltdl/lt_system.h: New installed header for system portability
abstraction.
* libltdl/ltdl.h: Use it.
* libltdl/lt__alloc.c, libltdl/lt__alloc.h: New module above
system portability layer to abstract ltdl's memory management.
* libltdl/ltdl.c: Use lt__alloc.h.
(closedir): Use free.
(opendir): Use malloc/free.
(lt__xalloc_die_callback): Report memory failures through
lt_dlerror.
(lt_dlinit): Use it to initialise memory management.
(LT_DLMALLOC, LT_DLREALLOC, LT_DLFREE, LT_EMALLOC, LT_EREALLOC)
(rpl_strdup, rpl_realloc, lt_estrdup, lt_emalloc, lt_erealloc):
Removed in favour of...
(lt__strdup, lt__memdup, MALLOC, REALLOC, FREE): ...these calls
from libltdl/lt__alloc.h. Changed all callers.
(rpl_argz_append, rpl_argz_create_sep, rpl_argz_insert): As part
of the portability layer, these functions no longer use libltdl
memory management API.
(free_vars): Factored out.
(LT_DLMEM_REASSIGN): While redoing memory handling, renamed...
* libltdl/lt__alloc.h (MEMREASSIGN): ...to this.
* libltdl/Makefile.am (AUTOMAKE_OPTIONS): Let automake track
dependencies automatically.
(pkgincludedir): Override from parent package's setting.
(pkginclude_HEADERS): Install lt_system.h.
(libltdl_la_SOURCES): Add new files.
* NEWS: Updated.

Add ltdl.h.
(ltdldatadir): New variable for installation directory of
libtoolize --ltdl files.
(ltdldata_DATA): Tell automake what files to copy there at install
time (and remove at unistall time!).
(local-install-files): Removed. This hack is not required

advanced than this.
* Makefile.am (install-data-hook, uninstall-local): Removed.
Libltdl files for libtoolize are installed by their own Makefile

$top_srcdir for headers.
(DEFS): Override the default HAVE_CONFIG_H with the config.h

added to the list, in exchange for appending loaders to the list
with O(N) rather than O(1). The longest the loader list can ever
get is 4 (on cygwin with dld installed) so it probably constitutes
a small speedup, in addition to making the code much more readable.
ltmain unconditionally.

which values to set these macros to.
* config.guess, config.sub, mkstamp: Moved from here...
* config/config.guess, config/config.sub, config/mkstamp: ...to

* libtool.m4, ltdl.m4: Moved from here...
* m4/libtool.m4, m4/ltdl.m4: ...to here, respectively.
* configure.ac: Removed various acinclude.m4 hackery, as these
files are no longer needed with automake 1.8.
* Makefile.am: Removed various acinclude.m4 hackery, as these
files are no longer needed with automake 1.8.
(AUTOMAKE_OPTIONS): Require CVS automake.
(CONF_SUBDIRS, CFLAGS, CPPFLAGS, LDFLAGS, LIBS, FFLAGS, FLIBS):
Automake now makes a Make variable from every AC_SUBST, so these
are NOP.
(aclocal_macros): These files are now in their own m4 subdir.

kept in the new config subdir.
* libltdl/configure.ac (AC_CONFIG_AUX_DIR): Removed. Defaults to
`.' anyway.
to maintain an lt_dlrealloc function pointer, it is too difficult
to implement realloc as malloc/memcpy/free without knowing the
size of the original block. rpl_realloc has been deprecated since

bite the bullet. Caller gets to maintain lt_dlrealloc:
* NEWS (1.5.1): Updated.
* libltdl/ltdl.c (LT_DLREALLOC): Use lt_dlrealloc so the user can
update the function pointer to match lt_dlmalloc.
(lt_emalloc): Use lt_dlrealloc rather than hardcoding realloc.
* doc/libtool.texi (Libltdl interface): Describe lt_dlrealloc now

* f77demo/Makefile.am: add -no-undefined flag
* ltdl.c (realloc): Remove custom realloc. (#define
rpl_realloc realloc) and comment out later code for custom
realloc. You can't define your own malloc unless you know
enough about the malloc in use to be able to tell how big
the src ptr is. The disabled code incorrectly used the
*destination* ptr to decide how much to copy. This
sometimes results in out-of-bound accesses which cause
segfaults. This is a quick hack for now; we may want
something cleaner later. (tryall_dlopen_module): check to

binutils' auto-export magic.

fail if it is unable to physically load the library. Sadly,
LoadLibrary will search the loaded libraries for a match and
return one of them if the path search load fails. Simulate a
failure in this case for compatibility with the other APIs.
Also, LoadLibrary takes the liberty of adding `.dll' to library
names passed without an extension, we now add a trailing `.' to
prevent this from happening.
decided that LoadLibrary returns `0' for success, yet FreeLibrary
returns `0' for failure! The FreeLibrary call used to interpret
`0' as success for both functions.
is no longer needed, as ld reverted to the original format.
* NEWS: Likewise.
* ltconfig.in: When testing self-dlopening, test whether dlclose
crashes. On FreeBSD 3.1, it does. :-(
* libltdl/configure.in: Likewise.
* NEWS: Note work-around.
Reported by Pavel Roskin <pavel_roskin@geocities.com>
(install-data-hook): use libltdl/Makefile.am's local-install files
rule.
* libltdl/Makefile.am (local-install-files): New rule to install
libltdl without creating links or mode 777 directories.
* instutil/*: deleted.
* cdemo/main.c: "Welcome _to_ ..."
* mdemo/main.c: ditto
* libltdl/configure.in: support multiple dlopening mechanisms
at once
* libltdl/ltdl.c: prefix system dependent functions with "sys_"
to avoid symbol conflicts (libdld didn't work)
* libtool.m4 (AC_LIBLTDL_*): set INCLTDL to the path of ltdl.h
* ltconfig.in: check for dlopen with -ldl first
* libltdl/configure.in: Clean up some duplicate defines. Enable
support for multiple dlopening mechanisms.
* libltdl/acconfig.h: New file. Add #undefs for defines that
would be duplicated.
* libltdl/ltdl.c (shl_close, shl_sym): use (shl_t *) instead of shl_t
* ltconfig.in (check for gcc): removed a bogus line,
check for shl_load in libdld
* ltmain.in: added a warning to the header of the .la file
to warn users against deleting the file,
link shared against static libraries if
deplibs_check_method == pass_all
* doc/libtool.texi: removed hardcode_into_libs documentation
* libtool.m4: some DJGPP fixes
* ltconfig.in: ditto, reverted one of my previous patches: we need
to check for NM, removed the hardcode_into_libs support since
no platform seems to support it
* ltmain.in: some DJGPP fixes, removed the hardcode_into_libs support
the deplibs check is now optional
* libltdl/configure.in: read libtool --config only once,
merged AC_SYS_SYMBOL_UNDERSCORE+AC_SYS_NM_PARSE from libtool.m4
* libtool.m4: AC_SYS_SYMBOL_UNDERSCORE+AC_SYS_NM_PARSE were not
used, lt_dlopen and silent may be empty, AC_SYS_LIBTOOL_CYGWIN
no longer necessary
* ltconfig.in: NM is already checked in libtool.m4,
* ltmain.in: always link all static dependency_libs
* tests/Makefile.am: added deplibs.test
* tests/demo-exec.test, demo-inst.test: removed hell0
* tests/deplibs.test: new test to test the deplibs_check_method
* libtoolize.in: add the libtool scripts to libltdl.tar.gz
* libtool.m4: don't AC_SUBST(USE_SYMBOL_UNDERSCORE),
AC_CHECK_LIBM sets LIBM, AC_LIBLTDL_INSTALLABLE doesn't work
when libltdl is already installed
* *demo/Makefile.am: use LIBM
* *demo/configure.in: AC_SUBST LIBM
* libltdl/configure.in: use ac_cv_sys_symbol_underscore instead of
USE_SYMBOL_UNDERSCORE
* ltconfig.in: added link_all_deplibs variable
* doc/libtool.texi: document it
* ltmain.in: always search for libname.la - don't eval libname_spec,
when linking libraries against static ones just print a warning
and add them to dependency_libs, add -lc before deplibs,
always link all dependencies of a static library or if
link_all_deplibs is yes, hardcode library paths if
hardcode_into_libs is no, don't link against dependency_libs
that already are deplibs
* README: updated (BeOS support, no longer shared libraries
support for AmigaOS), cleanups, we have now two mailing lists
* REAMDE-alpha: autogen -> bootstrap, we have now two mailing lists
* THANKS: added Xavier Pianet
* doc/PLATFORMS: BeOS works
* doc/libtool.texi: we have now to two mailing lists,
updated -dlopen self documentation, documented libltdl's license,
put each author in a separate line,
inter-library dependencies on uninstalled libtool libraries are
now supported, cleanups and minor corrections
* libltdl/COPYING.LIB: new file
* libltdl/ltdl.[ch]: added special exception to the LGPL license
* libtool.spec: removed, it was outdated
* Makefile.am: removed libtool.spec
* ltmain.in: use TMPDIR when possible, create a subdirectory
in the temporary directory, added -export-symbols-regex to the help,
* doc/PLATFORMS: Erez Zadok reported that libtool works on bsdi 4.0.1
* doc/libtool.texi (libltdl): libltdl supports BeOS
* libltdl/ltdl.c: shlib_ext was declared even if LTDL_SHLIB_EXT
didn't exist, partially reverted my previous patch: BeOS will
automatically search in ADDON_PATH
* ltmain.in: don't allow relative run-paths, fixed a typo in a warning,
ignore -dlopen self for libraries and objects,
only accept -L paths that exist, minor cleanups,
bugfix: add -lc for normal libraries, not convenicence libraries
removed offensive warnings/comments
library extension used to think the . in [.] for the cygwin
shared_library_names_spec was the start of the extension!! We now
remove anything in square brackets (assuming that the square
brackets delimit a sed or expr expression which is not part of the
extension) before looking for the extension.
* TODO (cygwin): food for thought re: mutually dependant dlls.
* NEWS: improved support for BeOS and Cygwin
* TODO: ILD branch was merged, all internal variables and macros
are now documented
* demo/Makefile.am: use $(LIBS) instead of -lm
* doc/libtool.texi: documented new variable hardcode_into_libs
and thread_safe_flag_spec, renamed all AM_ENABLE/DISABLE_* macros
to AC_*, documented AC_DISABLE_FAST_INSTALL and AC_LIBTOOL_DLOPEN
* libltdl/ltdl.c: added two new error messages (cannot_open_error,
cannot_close_error), use them where approriate,
BeOS support (thanks to Xavier Pianet), on BeOS search modules
additionally in ADDON_PATH
* libtool.m4: rewrote AC_CHECK_LIBM: BeOS and Cygwin don't have
libm and *-ncr-sysv4.3* requires libmw
* ltconfig.in: don't check for LoadLibrary, hardcode dlopen
configuration for BeOS and Cygwin
* ltmain.in: fix sourcing of .la files on Solaris
(patch by Raja R Harinath)
dlfcn.h and LTDL_LAZY exist; use LTDL_GLOBAL and LTDL_LAZY_OR_NOW.
This test is likely to fail if self-dlopening does not work,
especially because we do not link the program with
-export-dynamic. Let's just hope that platforms whose symbol
names start with underscores will also accept underscores for
dlopen. We should probably use libtool to compile and link this
test, so that we can use -export-dynamic.
avoid introducing multiple --enable options when re-running
config.status
* libltdl/configure.in: if enable_ltdl_* is not set, assume no
* configure.in: if enable_ltdl_install is not set, enable it
always configure libltdl, add libltdl/acinclude.m4 to
ACINCLUDE_M4_LIST, disable installation of libltdl if necessary
* libltdl/Makefile.am: set version info for libltdl.la
* libltdl/configure.in: don't check whether
enable_ltdl_convenience/install was set so that libltdl
can be used as independent package (libltdl.tar.gz) without
the need to use --enable-ltdl*
* libltdl/ltdl.c: minor cleanups, allocate the line cache
dynamically (lt_dlopen)
