Append stats to file + "BenchLog". + +Sun Nov 17 22:21:28 1996 Aubrey Jaffer + + * scm.texi (Socket): added examples of chat servers and clients. + (Internet Addresses and Socket Names): enlarged from "Internet + Addresses". + + * socket.c (l_connect): BUF0 was missing from mode bits set in + returned port. + +Sat Nov 16 22:02:39 1996 Aubrey Jaffer + + * build.scm (build-params): Added compiler-options and + linker-options; added --batch-dialect and --script-name as aliases + for -h and -w. + + * scmfig.h (HAVE_SELECT): Now defined for linux. + +Sat Nov 2 09:24:50 EST 1996 maximum entropy + + * ioext.c, scmfig.h: support for SGI (tested with SGI IRIX 5.2/gcc) + + * ioext.c (file_set_position): If a port is bidirectional + (e.g. a socket) it may be necessary on some systems to perform a + file positioning operation when switching between reading and + writing. This is required by ANSI C (ISO/IEC 9899:1990 + 7.9.5.3). Therefore, a file-set-position on a bidirectional + port should not signal an error if fseek generates an + ESPIPE -- the fseek operation actually "succeeded" in that it + reset the I/O direction flag for the FILE. + + * repl.c (input_waiting): R4RS requires that "char-ready?" + return "#t" at end-of-file. The semantics for "ioctl(..., + FIONREAD, ...)" are such that it gives 0 on a socket that is + closed (on the other side of the connection). If the + system has select(), use that instead to get the correct + behavior. + + * socket.c (l_listen): Treat sockets that have been "listened" + as input-ports. This allows polling for new connections + (e.g. with "char-ready?") instead of blocking in + "socket:accept". + + * socket.c (l_accept): Fix type checking to agree with + previous patch. + +Wed Nov 13 17:11:59 1996 Aubrey Jaffer + + * sys.c (igc): fixed off-by-1 error for sizeof save_regs_gc_mark. + (gc_mark): fixed off-by-1 error for sizeof(CONTINUATION). These + seem to fix a very obscure GC bug. + +Tue Oct 29 10:47:41 1996 Aubrey Jaffer + + * Init.scm (exec-self): Added. + + * repl.c (init_repl): DUMP sets RESTART to EXEC-SELF. + +Mon Oct 28 11:39:30 1996 Aubrey Jaffer + + * repl.c (tryload): Made tail-recursive so that dump, quit, exit, + etc. will work as the last expression in a loading file. + (scm_execpath): Split out from scm_unexec. + +Sun Oct 27 22:12:32 1996 Aubrey Jaffer + + * unexec.c: All Updated from emacs-19.34 -- no changes necessary. + * gmalloc.c: + * pre-crt0.c: + * ecrt0.c: + * unexelf.c: fixes Linux (ELF) dump bug. + +Mon Oct 21 21:49:20 1996 Aubrey Jaffer + + * build.scm (platform): linux renamed linux-aout. linux-elf fixed + and renamed linux. + (C-libraries): X11R6 moved library files on RedHat Linux.
