From a95a08b4af38992cbcf3d1da97199ef19528fbde Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Thu, 26 Aug 2004 18:35:05 +0000 Subject: Update. 2004-08-26 Ulrich Drepper * 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. * nscd/nscd_stat.c: Likewise. * nscd/grpcache.c: Likewise. * nscd/hstcache.c:: Likewise. * nscd/pwdcache.c:: Likewise. * nscd/Makefile: Add rules to build mem.c. * nscd/mem.c: New file. * nscd/nscd.conf: Describe new configuration options. --- nscd/nscd_getgr_r.c | 30 +++++++++++++----------------- 1 file changed, 13 insertions(+), 17 deletions(-) (limited to 'nscd/nscd_getgr_r.c') diff --git a/nscd/nscd_getgr_r.c b/nscd/nscd_getgr_r.c index d932624d19..b9cde73044 100644 --- a/nscd/nscd_getgr_r.c +++ b/nscd/nscd_getgr_r.c @@ -67,7 +67,7 @@ __nscd_getgrgid_r (gid_t gid, struct group *resultbuf, char *buffer, static int internal_function nscd_getgr_r (const char *key, size_t keylen, request_type type, - struct group *resbuf, char *buffer, size_t buflen, + struct group *resultbuf, char *buffer, size_t buflen, struct group **result) { gr_response_header gr_resp; @@ -115,17 +115,17 @@ nscd_getgr_r (const char *key, size_t keylen, request_type type, buflen -= total_len; p += align; - resbuf->gr_mem = (char **) p; + resultbuf->gr_mem = (char **) p; p += (1 + gr_resp.gr_mem_cnt) * sizeof (char *); /* Set pointers for strings. */ - resbuf->gr_name = p; + resultbuf->gr_name = p; p += gr_resp.gr_name_len; - resbuf->gr_passwd = p; + resultbuf->gr_passwd = p; p += gr_resp.gr_passwd_len; /* Fill in what we know now. */ - resbuf->gr_gid = gr_resp.gr_gid; + resultbuf->gr_gid = gr_resp.gr_gid; /* Allocate array to store lengths. */ len = (uint32_t *) alloca (gr_resp.gr_mem_cnt * sizeof (uint32_t)); @@ -133,7 +133,7 @@ nscd_getgr_r (const char *key, size_t keylen, request_type type, total_len = gr_resp.gr_mem_cnt * sizeof (uint32_t); vec[0].iov_base = len; vec[0].iov_len = total_len; - vec[1].iov_base = resbuf->gr_name; + vec[1].iov_base = resultbuf->gr_name; vec[1].iov_len = gr_resp.gr_name_len + gr_resp.gr_passwd_len; total_len += gr_resp.gr_name_len + gr_resp.gr_passwd_len; @@ -143,13 +143,13 @@ nscd_getgr_r (const char *key, size_t keylen, request_type type, goto out; /* Clear the terminating entry. */ - resbuf->gr_mem[gr_resp.gr_mem_cnt] = NULL; + resultbuf->gr_mem[gr_resp.gr_mem_cnt] = NULL; /* Prepare reading the group members. */ total_len = 0; for (cnt = 0; cnt < gr_resp.gr_mem_cnt; ++cnt) { - resbuf->gr_mem[cnt] = p; + resultbuf->gr_mem[cnt] = p; total_len += len[cnt]; p += len[cnt]; } @@ -157,21 +157,17 @@ nscd_getgr_r (const char *key, size_t keylen, request_type type, if (__builtin_expect (total_len > buflen, 0)) goto no_room; - if (gr_resp.gr_mem_cnt > 0 - && __builtin_expect (TEMP_FAILURE_RETRY (__read (sock, - resbuf->gr_mem[0], - total_len)) - != total_len, 0)) + retval = 0; + n = TEMP_FAILURE_RETRY (__read (sock, resultbuf->gr_mem[0], + total_len)); + if (__builtin_expect (n != total_len, 0)) { /* The `errno' to some value != ERANGE. */ __set_errno (ENOENT); retval = ENOENT; } else - { - retval = 0; - *result = resbuf; - } + *result = resultbuf; } else { -- cgit v1.2.3
