[BZ #2498]

accepted because of user-imposed limits close the descriptor.

2005-11-18 Jakub Jelinek <jakub@redhat.com>
* sysdeps/unix/sysv/linux/futimesat.c (futimesat): If FILE is NULL,
set access and modification times of the file referenced by FD.
* sysdeps/generic/futimesat.c (futimesat): Don't return EINVAL if
FILE is NULL. Don't check FD if FILE is absolute path.

* nscd/nscd_gethst_r.c (nscd_gethst_r): Avoid unnecesary read call
if there are no aliases.
* sysdeps/unix/sysv/linux/Makefile (CFLAGS-connections.c,
CFLAGS-pwdcache.c, CFLAGS-grpcache.c, CFLAGS-hstcache.c,
CFLAGS-aicache.c, CFLAGS-initgrcache.c): Add -DHAVE_SENDFILE.
* sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_SENDFILE):
Define.

mapping size even if it is bigger than the file size.
* nscd/mem.c (mempool_alloc): When resizing the file make sure the
limit in max_db_size is not exceeded. Don't use mremap, just
posix_fallocate is enough (according to Linus). Use posix_fallocate
correctly.
* nscd/nscd.conf: Add max-db-size parameters.
* nscd/nscd.h (struct database_dyn): Add max_db_size field.
Define DEFAULT_MAX_DB_SIZE and DEFAULT_DATASIZE_PER_BUCKET.

* nscd/connections.c (start_threads): Use sysconf in case
_POSIX_CLOCK_SELECTION or _POSIX_MONOTONIC_CLOCK is not greater zero.
* nscd/nscd.c: Remove getaddrinfo stub definition.
Dynamically create new threads if necessary.
* nscd/connections.c (fd_ready): If no thread available for processing
the request, create a new one unless the limit is reached.

* nscd/nscd.h: Declare max_nthreads.
* nscd/nscd_conf.c: Parse max-nthreads entry.

restart_interval, oldcwd, old_gid, old_uid.

are handled by one thread which then hands of the descriptors for the
real work to the worker threads.
* nscd/Makefile: Link nscd with librt.
* nscd/selinux.c: Pretty printing.
* nscd/dbg_log.c (dbg_log): Don't add unnecessary newline to
output. Let syslog do the formatting if debug_level == 0.
2004-09-10 Ulrich Drepper <drepper@redhat.com>
* nscd/nscd_stat.c: Improve output by also printing .shared and
.persistent.
* nscd/connections.c: Allow cache sharing to be really disabled.
* nscd/connections.c: Implement r/o sharing of nscd's cache with client
processes via shared memory.

no derived information.

not have found a ppc bug.
2004-08-26 Ulrich Drepper <drepper@redhat.com>
* nscd/cache.c: Major rewrite. The data is now optionally kept in
a mmaped memory region which is automatically mirrored on disk.
This implements persistent data storage. The Memory handled
needed to be completely revamped, it now uses a garbage collection
mechanism instead of malloc.
* nscd/connections.c: Likewise.
* nscd/nscd.c: Likewise.
* nscd/nscd.h: Likewise.
* nscd/nscd_conf.c: Likewise.

entry with alternative key.
* nscd/pwdcache.c (cache_addpw): Likewise.
