adding (weak definitions to) stubs for some of the pthread functions. If the threads library is linked in, the real pthread functions will pulled in. Use the following convention for system calls wrapped by the threads library: __sys_foo - actual system call _foo - weak definition to __sys_foo foo - weak definition to __sys_foo Change all libc uses of system calls wrapped by the threads library from foo to _foo. In order to define the prototypes for _foo(), we introduce namespace.h and un-namespace.h (suggested by bde). All files that need to reference these system calls, should include namespace.h before any standard includes, then include un-namespace.h after the standard includes and before any local includes. <db.h> is an exception and shouldn't be included in between namespace.h and un-namespace.h namespace.h will define foo to _foo, and un-namespace.h will undefine foo. Try to eliminate some of the recursive calls to MT-safe functions in libc/stdio in preparation for adding a mutex to FILE. We have recursive mutexes, but would like to avoid using them if possible. Remove uneeded includes of <errno.h> from a few files. Add $FreeBSD$ to a few files in order to pass commitprep. Approved by: -arch |

# @(#)README 8.27 (Berkeley) 9/1/94 This is version 1.85 of the Berkeley DB code. For information on compiling and installing this software, see the file PORT/README. Newer versions of this software will periodically be made available by anonymous ftp from ftp.cs.berkeley.edu. An archive in compressed format is in ucb/4bsd/db.tar.Z, or in gzip format in ucb/4bsd/db.tar.gz. If you'd like to receive announcements of future releases of this software, send email to the contact address below. Email questions may be addressed to Keith Bostic at bostic@cs.berkeley.edu. ============================================ Distribution contents: Makefile.inc Ignore this, it's the 4.4BSD subsystem Makefile. PORT The per OS/architecture directories to use to build libdb.a, if you're not running 4.4BSD. See the file PORT/README for more information. README This file. btree The B+tree routines. changelog List of changes, per version. db The dbopen(3) interface routine. docs Various USENIX papers, and the formatted manual pages. hash The extended linear hashing routines. man The unformatted manual pages. mpool The memory pool routines. recno The fixed/variable length record routines. test Test package. ============================================ Debugging: If you're running a memory checker (e.g. Purify) on DB, make sure that you recompile it with "-DPURIFY" in the CFLAGS, first. By default, allocated pages are not initialized by the DB code, and they will show up as reads of uninitialized memory in the buffer write routines.
