* elf/dl-close.c (_dl_close): If object has no r_list (i.e., wasn't
loaded directly) determine length if l_initfini list by iterating
over its elements. Minor optimizations.
* elf/dl-deps.c (_dl_map_object_deps): Always add own map to l_initfini
for dependency objects.
If object was already loaded check whether any of the dependencies
is already on the relocation dependency list. If yes, remove the
latter. Minor optimizations.
* elf/dl-lookup.c (add_dependency): Add check for self reference of
maps here. Search l_initfini list only if the object was loaded
directly and not only as a dependency.
(_dl_lookup_symbol): Add relocation dependency also if object
is not in global scope. Remove test for self-reference here.
(_dl_lookup_versioned_symbol): Likewise.
* elf/dl-object (_dl_new_object): Cleanup. Initialize dont_free
element of first name record.
* elf/loadtest.c: Add some more test to recognize early if an object
wasn't unloaded.
* elf/Makefile: Add rules to build and run reldep5.
* elf/reldep5.c: New file.
* elf/reldepmod5.c: New file.
* elf/reldepmod6.c: New file.
* elf/reldep2.c: Fix typo.
* elf/dl-object.c (_dl_new_object): Initialize l_scope and l_scope_max.
* elf/dl-lookup.c (add_dependency): Fix test to check whether
dependency already exists.
* elf/Makefile: Add testobj1 and testobj2 as dependencies of testobj6.
* elf/loadtest.c (main): Add test at the end that everything is
unloaded.
* elf/dl-open.c (dl_open_worker): Fix typo in comment.
2000-10-24 Ulrich Drepper <drepper@redhat.com>
Complete revamp of the reference counter handling.
* include/link.h (struct link_map): Add l_idx field.
* elf/dl-close.c: Handle decrementing of reference counters more
correctly. If necessary decrement reference counters of dependencies
of dependencies.
* elf/dl-lookup.c (add_dependency): Only increment reference counter
of the object itself and not also its dependencies.
* elf/dl-open.c: Increment reference counters here.
* elf/dl-deps.c: Remove reference counter handling here.
* elf/dl-load.c: Likewise.
* elf/rtld.c: Adjust for _dl_map_deps not handling reference counters.
* elf/loadtest.c: Print loaded objects at the beginning.
* elf/dl-close.c: Decrement opencount for all dependencies which can
be removed even if the object is not yet unloaded.
* elf/dl-deps.c (_dl_map_object_deps): If dependency is already in
the list decrement opencount of all dependencies.
* elf/dl-load.c (_dl_map_object_from_fd): Increment object of object
and all dependencies.
(_dl_map_object): Likewise.
* elf/dl-lookup.c (add_dependency): Likewise.
* elf/loadtest.c: Add debug when with more output.
2000-08-19 Ulrich Drepper <drepper@redhat.com>
* elf/Versions [ld] (GLIBC_2.2): Export _dl_check_map_versions.
* elf/dl-deps.c (_dl_map_object_deps): If object was dependency of
a dynamically loaded object remove old l_initfini list.
* elf/dl-libc.c (free_mem): Used as __libc_subfreeres callback to
remove some dynamically allocated memory blocks in the dynamic
loading data structures.
* elf/dl-load.c (add_name_to_object): Initialize dont_free to 0.
* elf/dl-open.c (dl_open_workder): Don't call _dl_check_all_versions.
Instead call _dl_check_map_versions only for the dependencies.
* elf/rtld.c: Avoid unneccessary initializations. Mark l_libname
information of initial objects as not free-able.
* sysdeps/generic/ldsodefs.h (struct libname_list): Add dont_free
element.
* elf/filter.c: Call mtrace.
* elf/restest1.c: Likewise. Close the objects.
* elf/loadtest.c: Call mtrace. Check result of dlclose. Print more
debug information.
* elf/constload1.c: Add comment explaining not freed memory.
1999-01-20 Ulrich Drepper <drepper@cygnus.com>
* elf/Makefile (tests): Add preloadtest. Add rules to build more test
modules and the preloadtest binary.
* elf/loadtest.c (TEST_ROUNDS): Increase to 1000.
(testobjs): Add more modules.
(tests): Add entries for new modules.
* elf/preloadtest.c: New file. Test for LD_PRELOAD.
* elf/testobj1.c: Add 'preload' function.
* elf/testobj2.c: Likewise.
* elf/testobj3.c: Likewise.
* elf/testobj4.c: New file.
* elf/testobj5.c: New file.
* elf/testobj6.c: New file.
