From 96bda0ea44eb94e0284e91f20ba9733ae63f26a5 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Tue, 2 Jul 1996 19:35:40 +0000 Subject: * nss/nss_files/files-network.c: Pass empty for new DB_LOOKUP args. (DATABASE): Define this instead of DATAFILE. * nss/nss_files/files-hosts.c: Likewise. (hostbyname): Use LOOKUP_NAME macro. * nss/nss_db/db-XXX.c: New file. * nss/Makefile (services): Add db. (libnss_db-inhibit-o): New variable. (libnss_db-routines): New variable. (distribute): Append db-XXX.c. (libnss_db.so): Depend on libdb.so and libnss_files.so. ($(libnss_db-routines:%=$(objpfx)%.c)): New static pattern rule. * nss/nss_files/files-XXX.c (DB_LOOKUP): Add KEYSIZE and KEYPATTERN args, ignored. (DATAFILE): New macro. * nss/nss_files/files-parse.c (GENERIC): If undefined, define to "files-XXX.c". * nss/nss_files/files-rpc.c: Include GENERIC instead of "files-XXX.c". Pass db key args to DB_LOOKUP. (DATAFILE): Macro removed. (DATABASE): New macro replaces it, lacks "/etc/" prefix. * nss/nss_files/files-service.c: Likewise. * nss/nss_files/files-pwd.c: Likewise. * nss/nss_files/files-proto.c: Likewise. * nss/nss_files/files-grp.c: Likewise. * nss/nss_files/files-ethers.c: Likewise. * elf/linux-compat.c: File removed. * elf/Makefile (distribute): Remove linux-compat.c. (ld-linux.so.1): Remove target and associated variables. * sunrpc/xdr.c: Remove malloc decl. * sunrpc/portmap.c: Likewise. * sunrpc/svc_tcp.c (abort): Don't declare. Instead define as macro casting abort to fn returning bool_t. * nss/nss_files/files-parse.c [EXTERN_PARSER]: Do an extern decl of the parser function. [EXTERN_PARSER] (LINE_PARSER): Define to empty. * nss/nss_files/files-pwd.c (EXTERN_PARSER): Define it. * nss/nss_files/files-grp.c: Likewise. * Makeconfig (BUILD_CC): If undefined, define to $(CC). * sunrpc/rpc/types.h: Include stdlib.h instead of declaring malloc. * Makeconfig (built-program-cmd): Use $(rtld-installed-name) in place of ld.so so lookups for that soname find it. * nss/Makefile (libnss_dns.so): Depend on libresolv.so. (resobjdir, LDLIBS-nss_dns.so): Variables removed. --- nss/nss_files/files-XXX.c | 10 +++++++--- nss/nss_files/files-ethers.c | 9 +++++---- nss/nss_files/files-grp.c | 16 ++++++---------- nss/nss_files/files-hosts.c | 18 +++++------------- nss/nss_files/files-network.c | 6 +++--- nss/nss_files/files-parse.c | 21 +++++++++++++++++++++ nss/nss_files/files-proto.c | 8 ++++---- nss/nss_files/files-pwd.c | 16 +++++++--------- nss/nss_files/files-rpc.c | 8 ++++---- nss/nss_files/files-service.c | 8 ++++---- 10 files changed, 66 insertions(+), 54 deletions(-) (limited to 'nss/nss_files') diff --git a/nss/nss_files/files-XXX.c b/nss/nss_files/files-XXX.c index b9c3579..7fa87c0 100644 --- a/nss/nss_files/files-XXX.c +++ b/nss/nss_files/files-XXX.c @@ -27,13 +27,15 @@ Cambridge, MA 02139, USA. */ ENTNAME -- database name of the structure and functions (hostent, pwent).
