* cache.c: Change cache/hash table size to 509, a prime. Use memcpy/memcmp not bcopy/bcmp. Verify return value from malloc and check the result of rpc transaction _and_ do not act if failed. * main.c: Correct the wording of the help messages. Do not bother initializing global variable to 0. Use memcpy/memcmp not bcopy/bcmp. Verify return value from malloc and check the result of rpc transaction _and_ do not act if failed. * mount.c: Check return values of initialize_rpc. Use memcpy/memcmp not bcopy/bcmp. Verify return value from malloc and strdup. Correct comments. (mount_root): Check result of connect. Handle errors consistently. Reverse loops that are if (! c) {} else when appropriate. * mount.h: Protect header with #ifdef. * name-cache.c: Correct dangerous NPARTIALS macro. Use memcpy/memcmp not bcopy/bcmp. (find_cache): Use PARTIAL_THRESH, not the constant. * nfs-spec.h: Protect header with #ifdef. * nfs.c: Use memcpy/memcmp not bcopy/bcmp. * nfs.h: Likewise. * ops.c (netfs_attempt_mkdir): Check return values of initialize_rpc. Use memcpy/memcmp not bcopy/bcmp. Verify return value from malloc and check the result of rpc transaction _and_ do not act if failed. (netfs_attempt_link): Unlock the directory before the rpc transaction. Check the result of rpc transaction _and_ do not act if failed. * pager.c: Remove, we do not use it. * rpc.c: Use memcpy/memcmp not bcopy/bcmp. Verify return value from malloc and check the result of rpc transaction _and_ do not act if failed. (initialize_rpc): Use AUTH_NONE, not the depreciated AUTH_NULL. Return sane values on failure. (generate_xid): Make inline. (link_rpc): New function. Complements unlink_rpc. (conduct_rpc): Use link_rpc. (rpc_receive_thread): Reroll to a single loop.

* ops.c (netfs_attempt_unlink): Purge cache-held references *before* counting live references. Use new function. * name-cache.c (purge_lookup_cache_node): New function. * nfs.h (purge_lookup_cache_node): New decl. * cache.c (netfs_node_norefs): Don't do delete RPC here, fork off a separate thread to do it. (struct fnd): New type. (forked_node_delete): New function.

* name-cache.c (check_lookup_cache): Use name_cache_neg_timeout in preference to name_cache_timeout for negative hits. * nfs.h (name_cache_neg_timeout): New variable. * main.c (DEFAULT_NAME_CACHE_NEG_TIMEOUT): New macro. (name_cache_neg_timeout): Initialize new variable. (OPT_NCACHE_NEG_TO): New option key. (common_options): Add --name-cache-neg-timeout switch. (parse_common_opt): Process OPT_NCACHE_NEG_TO option key. * ops.c (netfs_attempt_lookup): Do cast of -1 correctly to match check_lookup_cache and ANSI C rules. * name-cache.c (check_lookup_cache): Unlock DIR correctly before returning a negative cache hit. * rpc.c (rpc_receive_thread): Don't print "dropping reply" messages any more. * ops.c (netfs_attempt_lookup): Cash all lookups, both positive and negative. (netfs_attempt_mkdir): Purge cache before creating directory entry. (netfs_attempt_link): Likewise. (netfs_attempt_create_file): Likewise. * ops.c (netfs_attempt_lookup): Pass correct node to enter_lookup_cache as the child. Thu Jul 24 13:15:56 1997 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu> * name-cache.c: New file. * ops.c (netfs_attempt_lookup): Check lookup cache before trying RPC. After successful lookup, make cache entry. (netfs_attempt_unlink): Purge cache before doing operation. (netfs_attempt_rmdir): Likewise. (netfs_attempt_rename): Purge cache for both names before operation. * nfs.h (enter_lookup_cache, purge_lookup_cache, check_lookup_cache): New prototypes. * Makefile (SRCS): Add name-cache.c. * nfs.h (name_cache_timeout): New variable. * main.c (DEFAULT_NAME_CACHE_TIMEOUT): New macro. (name_cache_timeout): Initialize new variable. (OPT_NCACHE_TO): New option key. (common_options): Add --name-cache-timeout switch. (parse_common_opt): Process OPT_NCACHE_TO option key. * cache.c (lookup_fhandle): Don't parse NFS XDR format, instead take a length arg. Return void. All callers changed to use new function xdr_decode_fhandle. * nfs.c (xdr_decode_fhandle): New function. * nfs.h (xdr_decode_fhandle): New prototype. (lookup_fhandle): Update prototype.
