Update. 1998-10-18 Ulrich Drepper <drepper@cygnus.com> * resolv/nss_dns/dns-host.c: Add missing errnop parameter to the NSS functions. * resolv/nss_dns/dns-network.c: Likewise. * grp/Makefile: Don't search for linuxhtreads in add-ons, use have-thread-library to determine whether threads are available. * pwd/Makefile: Remove wrong comment. * inet/Makefile: Define CFLAGS-gethstbyad_r.c, CFLAGS-gethstbynm_r.c, and CFLAGS-gethstbynm2_r.c to -DUSE_NSCD=1. * locale/C-messages.c: Define default strings for YESTR and NOSTR. * nss/Versions: Add __nss_hosts_lookup. * nss/getXXbyYY.c: Remove unneeded assignment. * nss/getXXbyYY_r.c: Include nscd/nscd_proto.h only if needed. Almost complete rewrite of the NSCD to make it smaller, faster, add more functionnality and make it easier to extend. * nscd/Makfile (routines): Add nscd_gethst_r. (nscd-modules): Add hstcache, gethstbyad_r, gethstbynm2_r, and cache. * nscd/cache.c: New file. * nscd/gethstbyad_r.c: New file. * nscd/gethstbynm2_r.c: New file. * nscd/hstcache.c: New file. * nscd/nscd_gethst_r.c: New file. * nscd/connections.c: Rewritten. Don't start new thread for every new connection. Use a fixed set of threads which handle all connections and also the cache cleanup. * nscd/grpcache.c: Rewritten to use generic cache handling functions in cache.c. * nscd/nscd.c: Recognize new parameter nthreads. Adjust initialization for rewrite. Remove handle_requests function. * nscd/nscd.h (NSCD_VERSION): Bump to 2. Define new data structure for the new unified cache and the host database entries. * nscd/nscd_conf.c: Rewrite parsing partly to allow adding of more databases easily. Recognize check-files and threads definitions. * nscd/nscd.conf: Add definition of enable-cache and check-files to passwd and group definitions. Add new set of definitions for hosts. * nscd/nscd_getgr_r.c: Rewrite for new protocol. * nscd/nscd_getpw_r.c: Likewise. * nscd/nscd_proto.h: Add prototype for host database functions. * nscd/nscd_stat.c: Rewrite to simplify printing of information for many databases. * nscd/dbg_log.c: Remove unnecessary variable initializations. Global variable debug_flag is renamed to dbg_level. * nscd/dbg_log.h: Declare set_logfile.
