module, since HPUX adds module symbols into the `self' pool if
it is opened later. Return the cached pointer if the caller
subsequently tries to open `self'.
(sys_shl_sym): Diagnose NULL modules.
* ltmain.in (clean,uninstall): test -e is not portable. Well,
neither is -L, but I'm hoping that redirecting error messages
to /dev/null and relying on non-zero exit status will work okay
on the few hosts that don't support -L.
* tests/depdemo-dups.test: Removed, as part of the patch
reversion below.
* ltmain.in: Revert my change from 2001-03-31. Although it
was technically correct, it opens a whole can of worms we don't
want to deal with right now.
* libltdl/ltdl.c (sys_shl_open): Return a NULL module handle
for self opening.
(sys_shl_close): Be careful not to close a NULL module handle.
(sys_shl_sym): Allow shl_findsym() to open NULL modules, but
discard the modified module address it returns.
hardcodes the library path and adds versioning. Other small
fixes.
* ltmain.in: Fixed special cases for libc and libm on Rhapsody and
Darwin. One of them was misplaced. Added version_type case for
Rhapsody and Darwin, named "darwin".
from libtool link lines -- duplicates are somtimes necessary
to satisfy inter-library dependencies, and never cause link to
fail even if they are spurious.
* tests/depdemo-dups.test: New file. Make sure this bug doesn't
creep back in again!
* tests/Makefile.am (TESTS): Use the new test above.
to the following: libFOO.a (static lib), libFOO.dll.a (import
lib), cygFOO-version.dll (dll). Update postinstall_cmds and
postuninstall_cmds to reflect this.
* ltmain.in: Generate installed .la files with dlnames set to
../bin/cygFOO-version.dll for normal dlls. dlls for modules
remain with the .la file.
* libtool.m4 (export_symbols): On Windows, if the export_symbols
file (which has been passed to libtool with the -export-symbols
command line switch) already is a .def file, use it as is.
* doc/libtool.texi (Thread Safety in libltdl): New node describing
the application the new MT API.
* libltdl/ltdl.h: Prototypes.
* libltdl/ltdl.c: Use these functions throughout the rest of
the file to provide thread locking.
(lt_dlmutex_register): New function to set callbacks for
multi-threaded calls into libltdl.
(lt_dl_mutex_lock): Type of a locking callback function.
(lt_dl_mutex_lock): Type of an unlocking callback function.
(lt_dl_mutex_seterror): Type of a callback function to save the
last libltdl error message in thread local storage.
(lt_dl_mutex_geterror): Type of a callback function to retrieve
the last saved error message from thread local storage.
don't sweat -- it may be a lib that is already statically linked
into the loading application.
* libltdl/ltdl.c: Clean up the shadowing of the global handles
variable.
(LT_DLRESIDENT_FLAGS): Add extra parens to satisfy -Wall.
(load_deplibs): Cast isspace() argument to an int to satisfy
-Wall.
* doc/libtool.texi (User defined module data): Document it all.
* ltdl.m4: Check for memcpy, or else bcopy.
* ltdl.c (lt_caller_data): New type.
(lt_dl_handle_struct): Add an lt_caller_data field.
(lt_dlcaller_register, lt_dlcaller_set_data,
lt_dlcaller_get_data): New functions.
(rpl_memcpy): A minimal fallback implementation.
(rpl_realloc): A realloc implemented with lt_dlmalloc and
lt_dlfree.
(LT_DLMALLOC, LT_DLFREE, LT_DLREALLOC, LT_DLMEM_REASSIGN):
New memory handling convenience macros. Use them
appropriately throughout the rest of this file.
* ltdl.h (lt_dlcaller_register, lt_dlcaller_set_data,
lt_dlcaller_get_data): Prototyped.
