From 528741cb6c7218e7f2f764fa10aa7e67699eadaa Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sun, 18 May 2008 21:54:43 +0000 Subject: * nscd/cache.c (cache_add): Take additional parameter specifying whether this is in response of a cache refill. Check alignment of package data. Revamp waking of pruning thread. (prune_cache): Small optimization. * nscd/nscd.h: Adjust cache_add prototypes. * nscd/aicache.c: Adjust cache_add calls. * nscd/grpcache.c: Likewise. * nscd/hstcache.c: Likewise. * nscd/initgrcache.c: Likewise. * nscd/pwdcache.c: Likewise. * nscd/servicescache.c: Likewise. * nscd/connections.c (restart): Really disable cache use before exec attempt. If it fails, reenable cache. (nscd_run_prune): Initialize wakeup_time. After wakeup, set wakeup time to max to be able to notice concurrent cache additions. Unlock prune_lock while performing gc. Afterwards compute wakeup time with current wakeup_time value in mind. --- nscd/grpcache.c | 11 ++++++----- 1 file changed, 6 insertions(+), 5 deletions(-) (limited to 'nscd/grpcache.c') diff --git a/nscd/grpcache.c b/nscd/grpcache.c index 9921ae3..e391dc3 100644 --- a/nscd/grpcache.c +++ b/nscd/grpcache.c @@ -147,7 +147,7 @@ cache_addgr (struct database_dyn *db, int fd, request_header *req, pthread_rwlock_rdlock (&db->lock); (void) cache_add (req->type, &dataset->strdata, req->key_len, - &dataset->head, true, db, owner); + &dataset->head, true, db, owner, he == NULL); pthread_rwlock_unlock (&db->lock); @@ -353,7 +353,7 @@ cache_addgr (struct database_dyn *db, int fd, request_header *req, if (req->type == GETGRBYGID) { if (cache_add (GETGRBYGID, cp, key_offset, &dataset->head, true, - db, owner) < 0) + db, owner, he == NULL) < 0) goto out; first = false; @@ -362,7 +362,7 @@ cache_addgr (struct database_dyn *db, int fd, request_header *req, else if (strcmp (key_copy, gr_name) != 0) { if (cache_add (GETGRBYNAME, key_copy, key_len + 1, - &dataset->head, true, db, owner) < 0) + &dataset->head, true, db, owner, he == NULL) < 0) goto out; first = false; @@ -372,12 +372,13 @@ cache_addgr (struct database_dyn *db, int fd, request_header *req, if ((req->type == GETGRBYNAME || db->propagate) && __builtin_expect (cache_add (GETGRBYNAME, gr_name, gr_name_len, - &dataset->head, first, db, owner) + &dataset->head, first, db, owner, + he == NULL) == 0, 1)) { if (req->type == GETGRBYNAME && db->propagate) (void) cache_add (GETGRBYGID, cp, key_offset, &dataset->head, - false, db, owner); + false, db, owner, false); } out: -- cgit v1.1
