libtool/tests/TODO

Please write the following testcases and submit to libtool-patches@gnu.org:

 - ensure each libtool library 'originator' is tried.
 - check that passing NULL as the 'originator' correctly loads all
   preloaded modules originating from "self" (program itself).
 - test whether a preloaded library will open without the matching
   .la file.
Add a test to simulate a failure visible on systems which need a library prefix like 'lib', such as BeOS. Fix a number of bugs exposed by this test in order for it to pass. Currently the prefix is hardcoded as 'lib', as I am not aware of systems that require a different prefix: * libltdl/loaders/preopen.c (lt_dlpreload_open): Move error condition out of test loop to be sure that each originator is tried, instead of erroring out if the first doesn't match. Support passing NULL as the originator to load all preloaded modules originating in the program itself. * libltdl/lt_dlloader.c (lt_dlloader_dump): New debug function. * libltdl/libltdl/lt_dlloader.h (lt_dlloader_dump): Declare it when LT_DEBUG_LOADERS is defined at compile time. * libltdl/ltdl.c (lt_dlinit): Dump loader list after successful initialisation. (tryall_dlopen): Add a new VTABLE parameter to force use of a specific loader in preference to trying every loader in turn. Adjust all callers. (try_dlopen): Always see whether a module was preloaded for module names with no directory component before searching the filesystem for a match. * libltdl/m4/libtool.m4 (_LT_CMD_GLOBAL_SYMBOLS): Declare a new global_symbol_to_c_name_address_lib_prefix variable. (global_symbol_to_c_name_address_lib_prefix): The sed expressions to use when a lib prefix is enforced need to be slightly different to work with preloaded modules. * libltdl/config/ltmain.m4sh (func_generate_dlsyms): In order to name preloaded symbols correctly for the lookup algorithm to work when the loaded module file must be prefixed with lib. Use global_symbol_to_c_name_address_lib_prefix when need_lib_prefix is other than no. * tests/need_lib_prefix.at: New test to check for breakage on hosts where need_lib_prefix is unknown. * Makefile.am (TESTSUITE_AT): Add new test. * tests/TODO: Note missing tests that would have caught some of the latent bugs fixed by this patch. * HACKING: Document libltdl keyword. * NEWS: Updated. 2007-06-25 04:46:47 +08:00			`Please write the following testcases and submit to libtool-patches@gnu.org:`
