This pervasive changeset makes two intertwined deep changes to the
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/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).

of zeroed out new memory.

* libltdl/lt__private.h (lt__alloc_die_callback): Add missing
prototype.
(lt__error_strings): Make this opaque to callers.

COMPATIBILITY*

paramater list.

(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.

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

rest of the code. Generate originator keyed symbol lists.
(func_extract_archives): Also factored. Extract the contents of

[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.

Keywords:
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.

Getting the value of ltdldatafiles from a submake was not
portable, and had problems with GNU make-3.80 at least. This
changeset pulls the installation rules for libtoolize's copy of
the libltdl sources out of libltdl/Makefile.am so that
ltdldatafiles is defined in the same Makefile that uses it. Also,
this makes a start at cleaning up libltdl/Makefile.am so that it
is useful in a package that uses `libtoolize --ltdl':
* libltdl/loaders/Makefile.am: Removed entirely.
* libltdl/Makefile.am (dlopen.la, dld_link.la, dyld.la)
(load_add_on.la, loadlibrary.la, shl_load.la): All built from here
now that the loaders submake has gone.
(show-ltdldatafiles): Removed. No longer required.
(ltdldatadir, ltdldatafiles, install-local): Moved from here...
* Makefile.am (ltdldatadir, ltdldatafiles, install-local): ..to

(libtoolize): Substitute $(ltdldatafiles) directly without calling

This pervasive changeset makes two intertwined deep changes to the
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):

Getting the value of ltdldatafiles from a submake was not
portable, and had problems with GNU make-3.80 at least. This
changeset pulls the installation rules for libtoolize's copy of
the libltdl sources out of libltdl/Makefile.am so that
ltdldatafiles is defined in the same Makefile that uses it. Also,
this makes a start at cleaning up libltdl/Makefile.am so that it
is useful in a package that uses `libtoolize --ltdl':
* libltdl/loaders/Makefile.am: Removed entirely.
* libltdl/Makefile.am (dlopen.la, dld_link.la, dyld.la)
(load_add_on.la, loadlibrary.la, shl_load.la): All built from here
now that the loaders submake has gone.
(show-ltdldatafiles): Removed. No longer required.
(ltdldatadir, ltdldatafiles, install-local): Moved from here...
* Makefile.am (ltdldatadir, ltdldatafiles, install-local): ..to
here.
(libtoolize): Substitute $(ltdldatafiles) directly without calling
make to get the value from libltdl/Makefile.

This pervasive changeset makes two intertwined deep changes to the
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.
