Append stats to file + "BenchLog". + * 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. + * 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. + * 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. + * Init.scm (exec-self): Added. + * repl.c (init_repl): DUMP sets RESTART to EXEC-SELF. + * 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. + * 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. + * build.scm (platform): linux renamed linux-aout. linux-elf fixed + and renamed linux. + (C-libraries): X11R6 moved library files on RedHat Linux. Linux + graphics library now has entry (doesn't default). + (compile-dll-c-files linux): + (make-dll-archive linux): Now converts from ".o" objects to ELF + ".so" form and "links" the usual libraries. + * Link.scm (usr:lib x:lib): dynamic linking fixed for (linux ELF) + dlopen. Libraries other than ".so" object not needed; eliminated + by usr:lib and x:lib returning #f. + * dynl.c (l_dyn_unlink): prints result of dlerror() on errors. + * eval.c (nconc2last): If CAUTIOUS is defined, checks that + APPLY's arglist and last element of arglist are LIST?s. + * sys.c (igc): symhash GC can now be disabled with + #define NO_SYM_GC. + * Init.scm (boot-tail): Added FSF --help and --version options. + Added --no-init-file as a synonym for -no-init-file. + * scm.texi (File-System Habitat): improved wording and added + examples. + * scm.texi (Top): Renamed sections. + * sys.c (mark_syms mark_sym_values): Split up mark_symhash() to + immunize against accidental pointers. + * repl.c (gc_ports_collected): added to instrument symbol GC. + * scm.texi (Debugging Scheme Code): Added section. + * eval.c (definedp): Changed from a memoizing macro to a `syntax'. + + From maximum entropy <entropy@zippy.bernstein.com>: + + * 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. + + From Radey Shouman <shouman@zianet.com> + + * eval.c (unmemocar): The code in unmemocar to deal with ILOCs was + never being executed. + * sys.c (intern): fixed (new) symhash GC bug. + * sys.c (igc): Added calls to mark_symhash() and sweep_symhash(). + These GC unused symbols with a top-level value of UNDEFINED. + (mark_symhash): added. + (sweep_symhash): added. + + From Eric Hanchrow <erich@MICROSOFT.com> + + * scm.c (l_sleep): Ported to Windows NT (_WIN32) + * ioext.c: Ported to Windows NT (_WIN32) + + -=-=- + +Scm conforms to Revised^4 Report on the Algorithmic Language Scheme +and the IEEE P1178 specification.
