Append stats to file + "BenchLog". + +Sun Nov 17 22:21:28 1996 Aubrey Jaffer <jaffer@localhost.bertronics.com> + + * 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 <jaffer@localhost.bertronics.com> + + * 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 <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. + +Wed Nov 13 17:11:59 1996 Aubrey Jaffer <jaffer@localhost.bertronics.com> + + * 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 <jaffer@localhost.bertronics.com> + + * Init.scm (exec-self): Added. + + * repl.c (init_repl): DUMP sets RESTART to EXEC-SELF. + +Mon Oct 28 11:39:30 1996 Aubrey Jaffer <jaffer@localhost.bertronics.com> + + * 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 <jaffer@localhost.bertronics.com> + + * 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 <jaffer@martigny.bertronics> + + * 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.

Now promotes 0-d arrays as well as scalars to match + first array shape. + (sc2array): Reshapes 0-d arrays as well as scalars. + Added check to make sure 2nd argument is really an array, + vector or uve. + (ramapc): Changed to allocate fewer array headers when arguments + are 1-d arrays. (Still allocates more than strictly necessary.) + (array_copy): Added check for scalar destination argument, since + ra_matchp() will now promote scalars to arrays. + +Sun May 12 00:52:51 1996 Aubrey Jaffer <jaffer@jacal.bertronics> + + * build.scm (build): fixed HP-UX compile-dll-c-files. + + * findexec.c (dld_find_executable): ifdefed out stat() for hpux. + + * scm.c: New const declarations rejected by hp-ux cc; ifdefed out. + +Thu May 9 10:28:14 1996 Tim Pierce <twpierce@midway.uchicago.edu> + + * time.c sys.c findexec.c: string[s].h configuration for Solaris + 2.3 system using gcc 2.7.2. + +Tue Apr 9 19:46:21 1996 Aubrey Jaffer <jaffer@jacal.bertronics> + + * sys.c (igc): stackbase argument added.

Written only for DLD. Needs to be repeated + for other dynamic linking regimes. + +Tue Apr 25 10:24:42 1995 Aubrey Jaffer (jaffer@jacal) + + * subr.c (make_string): Was silently failing for illegal 2nd args! + +Sat Apr 15 23:18:47 1995 Aubrey Jaffer (jaffer@jacal) + + * Link.scm (catalog:add-link): When feature is already in catalog, + will only add new feature association to catalog if file exists. + +Sun Apr 9 22:59:46 1995 Aubrey Jaffer (jaffer@jacal) + + * repl.c (repl_driver): Now closes load port when ABORTing. + +Sat Apr 8 21:35:43 1995 Aubrey Jaffer (jaffer@jacal) + + From: Tom Lord <lord@cygnus.com> + * scm.texi: + Tcl Facilities:: Mutual calling between Tcl and Scheme. + Tk Facilities:: Accessing Tk from Scheme. + Gwish:: A Wish-like application of Guile. + System Calls:: Psst.

The VMS `fwrite' has been enhanced to work with + VMS's Record Management Sevice, RMS. Part of this enhancement is + to treat each call to `fwrite' as producing a seperate record. + This works fine if you are writing to a stream_LF file or an + actual terminal screen, but if you are writing to a file that has + implied carriage control (such as a batch log file, or a mailbox + used for subprocess communication), which is a more common file + organization for RMS, each call to `fwrite' has a newline appended + to it. This causes much of the output to be incorrectly split + across lines. + + * vmsgcc.com: created. + +Sun Dec 1 00:33:42 1991 Aubrey Jaffer (jaffer at Ivan) + + * patchlvl.h (PATCHLEVEL): 3 released. + + * Init.scm (rev2-procedures): all now supported. + + * Init.scm sys.c MANUAL (flush): flush changed to force-output to + be compatible with Common Lisp. + + * sys.c (chdir): added. + +Wed Nov 27 09:37:20 1991 Aubrey Jaffer (jaffer at Ivan) + + * patchlvl.h (PATCHLEVEL): 2 + + * repl.c (set-errno! perror): added. + + * sys.c (gc): FLUSH_REGISTER_WINDOWS call added. + + * sys.c (open-input-pipe open-output-pipe close-pipe): added. + +Mon Nov 25 13:02:13 1991 Aubrey Jaffer (jaffer at Ivan) + + * patchlvl.h (PATCHLEVEL): 1 + + * sys.c (flush): added. + + * repl.c (mytime): macro was missing ().
