* libguile/weak-vector.c: * libguile/weak-vector.h: Renamed from weaks.[ch]. Remove weak pairs. They were not safe to access with `car' and `cdr'. Remove weak alist vectors, as we have weak tables and sets. Reimplement weak vectors, moving the implementation here. * libguile/vectors.c: * libguile/vectors.h: Remove the extra header word. Use scm_c_weak_vector_ref / scm_c_weak_vector_set_x to access weak vectors. * libguile/snarf.h: Remove the extra header word in vectors. * libguile/threads.c (do_thread_exit, fat_mutex_lock, fat_mutex_unlock): Instead of weak pairs, store thread-owned mutexes in a list of one-element weak vectors. * libguile/guardians.c (finalize_guarded): Similarly, store object guardians in a list of one-element weak vectors. * libguile/modules.c (scm_module_reverse_lookup): We no longer need to handle the case of weak references. * libguile/print.c (iprin1): Use the standard vector accessor to print vectors. * libguile.h: * libguile/Makefile.am: * libguile/gc-malloc.c: * libguile/gc.c: * libguile/goops.c: * libguile/init.c: * libguile/objprop.c: * libguile/struct.c: Update includes. * module/ice-9/weak-vector.scm: Load weak vector definitions using an extension instead of %init-weaks-builtins. * test-suite/tests/weaks.test: Use the make-...-hash-table names instead of the old alist vector names.
