From 67479a700e3bd2e52980c00ac35c888589ac0a36 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sun, 18 Oct 1998 15:16:22 +0000 Subject: Update. 1998-10-18 Ulrich Drepper * 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. --- nscd/nscd_conf.c | 94 +++++++++++++++++++++++++++++++++++++++----------------- 1 file changed, 66 insertions(+), 28 deletions(-) (limited to 'nscd/nscd_conf.c') diff --git a/nscd/nscd_conf.c b/nscd/nscd_conf.c index 917fe02..6ac1677 100644 --- a/nscd/nscd_conf.c +++ b/nscd/nscd_conf.c @@ -22,17 +22,27 @@ #include #include #include +#include #include #include "dbg_log.h" #include "nscd.h" +/* Names of the databases. */ +const char *dbnames[lastdb] = +{ + [pwddb] = "passwd", + [grpdb] = "group", + [hstdb] = "hosts" +}; + int -nscd_parse_file (const char *fname) +nscd_parse_file (const char *fname, struct database dbs[lastdb]) { FILE *fp; char *line, *cp, *entry, *arg1, *arg2; size_t len; + int cnt; /* Open the configuration file. */ fp = fopen (fname, "r"); @@ -92,41 +102,64 @@ nscd_parse_file (const char *fname) if (strcmp (entry, "positive-time-to-live") == 0) { - if (strcmp (arg1, "passwd") == 0) - set_pos_pwd_ttl (atol (arg2)); - else if (strcmp (arg1, "group") == 0) - set_pos_grp_ttl (atol (arg2)); - else + for (cnt = 0; cnt < lastdb; ++cnt) + if (strcmp (arg1, dbnames[cnt]) == 0) + { + dbs[cnt].postimeout = atol (arg2); + break; + } + if (cnt == lastdb) dbg_log ("server %s is not supported\n", arg1); } else if (strcmp (entry, "negative-time-to-live") == 0) { - if (strcmp (arg1, "passwd") == 0) - set_neg_pwd_ttl (atol (arg2)); - else if (strcmp (arg1, "group") == 0) - set_neg_grp_ttl (atol (arg2)); - else - dbg_log (_("service %s is not supported"), arg1); + for (cnt = 0; cnt < lastdb; ++cnt) + if (strcmp (arg1, dbnames[cnt]) == 0) + { + dbs[cnt].negtimeout = atol (arg2); + break; + } + if (cnt == lastdb) + dbg_log ("server %s is not supported\n", arg1); } else if (strcmp (entry, "suggested-size") == 0) { - if (strcmp (arg1, "passwd") == 0) - set_pwd_modulo (atol (arg2)); - else if (strcmp (arg1, "group") == 0) - set_grp_modulo (atol (arg2)); - else - dbg_log (_("service %s is not supported"), arg1); + for (cnt = 0; cnt < lastdb; ++cnt) + if (strcmp (arg1, dbnames[cnt]) == 0) + { + dbs[cnt].module = atol (arg2); + break; + } + if (cnt == lastdb) + dbg_log ("server %s is not supported\n", arg1); + } + else if (strcmp (entry, "enable-cache") == 0) + { + for (cnt = 0; cnt < lastdb; ++cnt) + if (strcmp (arg1, dbnames[cnt]) == 0) + { + if (strcmp (arg2, "no") == 0) + dbs[cnt].enabled = 0; + else if (strcmp (arg2, "yes") == 0) + dbs[cnt].enabled = 1; + break; + } + if (cnt == lastdb) + dbg_log ("server %s is not supported\n", arg1); } - else if (strcmp (entry, "enable-cache") ==0) + else if (strcmp (entry, "check-files") == 0) { - if (strcmp (arg1, "passwd") == 0 - && strcmp (arg2, "no") == 0) - disabled_passwd = 1; - else if (strcmp (arg1, "group") == 0 - && strcmp (arg2, "no") == 0) - disabled_group = 1; - else - dbg_log (_("service %s is not supported"), arg1); + for (cnt = 0; cnt < lastdb; ++cnt) + if (strcmp (arg1, dbnames[cnt]) == 0) + { + if (strcmp (arg2, "no") == 0) + dbs[cnt].check_file = 0; + else if (strcmp (arg2, "yes") == 0) + dbs[cnt].check_file = 1; + break; + } + if (cnt == lastdb) + dbg_log ("server %s is not supported\n", arg1); } else if (strcmp (entry, "logfile") == 0) { @@ -137,7 +170,12 @@ nscd_parse_file (const char *fname) { int level = atoi (arg1); if (level > 0) - debug_flag = level; + debug_level = level; + } + else if (strcmp (entry, "threads") == 0) + { + if (nthreads == -1) + nthreads = MAX (atol (arg1), lastdb); } else dbg_log (_("Unknown option: %s %s %s"), entry, arg1, arg2); -- cgit v1.1
