Don't alter cursX. Wed Mar 23 16:34:27 1988 Richard M. Stallman (rms at wilson) * x11term.h: Use X11/ not X/ for dir of include files. * xmenu.c: Likewise, in the X11 case. * m-7300.h: Fix unterminated comment near end. * s-xenix.h: Define n_zeroes so usage of struct nlist in fns.c works. * term.c (fatal): Do fflush(stderr). * sink11.h, sink11msk.h: New files. * x11term.h: Define CLASS here. Don't define X11 since this is included only if X11. * x11term.c: Use sink11.h and sink11msk.h, not sink.h and sinkmask.h. Don't define CLASS. Delete everything about BIGDEBUG. Delete everything pertaining to read_events_block. (XXidentity): now global. (CursorOutline): New var; nonzero means cursor is hollow. (XXicon_usebitmap): New var; nonzero means use bitmap icon.

Clean up docstring. * sysdep.c [VMS] (input_wait_timeout, wait_for_kbd_input): Use detect_input_pending, not get_input_pending. * process.c (wait_reading_process_input): Use only detect_input_pending to check for pending kbd input. (That `select' saw something on channel 0 doesn't mean it is kbd input; it could be an expose event.) * keyboard.c (read_avail_input) [FIONREAD]: Now static. New arg specifies value of NREAD; if it is nonzero, don't call get_input_pending to get it. Use kbd_buffer_store_char to put chars into kbd_buffer. Always abort if kbd_count is nonzero at start. Don't call {set,clear}_waiting_for_input. (get_input_pending): Now static. Return immediately if kbd_count > 0 or if Vquit_flag is non-nil. If FIONREAD and not interrupt_input and read_socket_hook, call read_avail_input to see how much pending input is really kbd characters; don't say we have some if an expose event is pending. * dispnew.c (init_display): Check result of egetenv for emptiness as well as nullness. Mon Mar 21 00:24:51 1988 Richard M. Stallman (rms at wilson) * alloca.s [WICAT]: Don't clobber a2. Return value in a0 and in d0. Sun Mar 20 13:33:54 1988 Richard M.

[M68K]: Define splevel% with `comm' -- put it in bss space. * sysdep.c [MISSING_UTIMES]: Define `utimes' as a no-op. * s-hpux.h: Define MISSING_UTIMES. * buffer.c (Fbuffer_local_variables): The buffer's alist can be out of date for a non-current buffer, so call Fsymbol_value to make the alist up to date. * sysdep.c [VMS] (end_kbd_input): If ast_active, don't clobber any global variables. * ymakefile (alloca.o): Copy sed output to a .s file and use cc to run the assembler. I hear Xenix can't run it directly. * sysdep.c [XENIX]: Undefine TIOCGETC. * s-xenix.h: Undefine NLIST_STRUCT. Put `_' in defn of LDAV_SYMBOL. Define HAVE_SYSVIPC. * m-intel386.h [XENIX] (LIB_STANDARD): Add /lib/386/Slibcfp.a. [XENIX] (FSCALE): Define it. [XENIX] (C_ALLOCA): Undefine it. * alloca.s: Define alloca for Xenix. Sat Mar 19 00:20:10 1988 Richard M. Stallman (rms at wilson) * keyboard.c (read_avail_input): If `read' gives EAGAIN, kbd_count should be 0. Can happen on V.3. * x11fns.c (Vxterm1): Delete this variable, and lisp var `xterm'. (syms_of_xfns): If CANNOT_DUMP and not `noninteractive', init_display has already set up Vxterm, so don't init it here. * display.c (syms_of_display): Likewise for Vwindow_system. (init_display): Always set Vwindow_system. Fri Mar 18 13:37:35 1988 Chris Hanson (cph at kleph) * m-hp9000s300.h: Add a definition for C_SWITCH_MACHINE which is needed to compile the X11 interface files. * s-hpux.h, m-hp9000s300.h, m-hp9000s800.h: Version 6.01 of HP-UX (on 300 machines only) implements symbolic links and supplies BSD procedures like `bcopy' and `index' as part of the BSD library. Move definitions which depend on these features from the s- file to the m- files, and conditionalize the features based on a flag. Fri Mar 18 16:03:27 1988 Richard M. Stallman (rms at wilson) * scroll.c (calculate_scrolling): Abort if ->insertcount is out of range. * sysdep.c (getwd for USG): Don't define it if HAVE_GETWD. * m-stride.h: Define HAVE_GETWD. * buffer.c (init_buffer): If `getwd' fails, it's a fatal error. * ymakefile (MAKE_PARALLEL): New name for PARALLEL, and now a cpp macro, not a Make variable. Defaults to empty. * m-sequent.h: Define MAKE_PARALLEL. * xdisp.c (display_text_line): Handle the overlay arrow last of all, and update line->length for the space it uses. * xmenu.c: Conditionals for X11, using new macro X11ONLY. Currently named x11menu.c until someone tests it. * ymakefile: Handle HAVE_X_MENU and use xmenu.o, even if X11. * x11term.h: Define BLOCK_INPUT, UNBLOCK_INPUT, BLOCK_INPUT_DECLARE. * Makefile: Set $(MAKE), since some Make versions don't have it. (xmakefile): Delete lines that are just one OR MORE whitespace chars. Use \t to represent the tab in the `sed' command. * fileio.c (Finsert_file_contents) [APOLLO]: Do another `stat' after closing the file. Gets around kernel bug (in `fstat'?). * fileio.c (Fwrite_region) [ALLIANT]: Don't do `fsync'; kernel bug. * sysdep.c (sys_suspend): If forking shell, call close_process_descs. Sat Feb 13 03:43:55 1988 Richard Stallman (rms at sugar-smacks.ai.mit.edu) * Version 18.50 released. * sysdep.c [VMS]: Remove VMS4_6 conditional on execvp & rename since s-vms.h is set to make us use our own definitions of these. Make execvp call `error' instead of `croak'. * s-vms.h: PURESIZE 132000. * m-sun2.h: Likewise (for HAVE_SUN_WINDOWS). Thu Feb 11 01:01:27 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu) * callproc.c (child_setup): Call close_process_descs if can have subprocesses. Close the argument-descriptors after copying them to 0, 1 and 2. * callproc.c (Fcall_process): After fork, in subprocess, explicitly close Emacs's end of the pipe. Don't bother calling set_exclusive_use. * process.c (close_process_descs): Close all descriptors that are talking to subprocesses.

Mon Feb 8 22:43:18 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu) * sysdep.c (init_sys_modes) [USG]: Set C-g for VQUIT as well as VINTR. This was formerly done only on HPUX, and worked there. It appears that all sysV is like HPUX in that CDEL does not really turn off the signal--it makes Meta-DEL cause the signal! * process.c (wait_reading_process_output): Change the test on read_kbd to avoid losing on 80386 Xenix.

Fri Jan 29 08:49:32 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu) * eval.c (unbind_to): Recompute loop end-test from `count' each time since an unwind-protect function can use realloc to grow the specpdl. Tue Jan 26 08:35:55 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu) * sysdep.c (vms_truncate) [VMS]: New fn to truncate a file. * fileio.c (Fwrite_region) [VMS]: If writing auto-save file, truncate any existing file. * s-vms.h: Rename `rename', `execvp' and `system' so we don't use the VMS-library versions of it.

Ultrix 2.0 has a TCSETAW but it requires a struct termio. Since HAVE_TERMIO is not set, sysdep uses struct sgttyb, and the real TCSETAW does not work with this. * sysdep.c (getwd): Discard everything before first slash. * termcap.c (tgetent): Delete VMS code to delete / from filename. * termcap.c (legal_filename_p): Use symbolic constant. * sysdep.c (sys_abort) [VMS]: New function; calls debugger. * sysdep.c (sys_access) [VMS]: Completely rewritten.

Stallman (rms at prep) * m-alliant.h, crt0.c for alliant: Must save _curbrk when dumping (from ADJUST_EXEC_HEADER) and restore it in crt0, because _curbrk itself isn't dumped. * unexec.c: Add a separate unexec routine for mips machines. No code is shared with normal unexec. Sun Mar 8 08:15:50 1987 Richard M. Stallman (rms at prep) * sysdep.c (baud_convert): Use new macro BAUD_CONVERT to override the standard conversion table. Use standard table if macro's not defined. * s-vms.h, s-hpux.h: Definitions of BAUD_CONVERT. * editfns.c (Fsubst_char_in_region): Call modify_buffer before changing it, and pass entire region.

Stallman (rms at prep) * fileio.c (Fwrite_region): Really put the `fstat' after the `fsync', trying to solve spurious "file has changed" warnings. This reverses a change made on Jan 28 which was described then as putting the `fstat' after the `fsync' but which in fact was exactly the opposite. The truth is that anciently the `fstat' was after, and on Jan 28 it was moved before. The change on Jan 28 was to fix some sort of RFS problem. I don't know whether the change itself or just its description was incorrect. * Version 18.38 released. Sat Feb 28 21:36:31 1987 Chris Hanson (cph at prep) * fileio.c: Added `sysnetunam' function for controlling remote file access connections under hp-ux. * s-hpux (LIBS_SYSTEM): Added `-ln' which is used by `sysnetunam'.

Mon Feb 23 02:59:45 1987 Richard M. Stallman (rms at prep) * keymap.c (access_keymap): No longer check lower case equivalent of an upper case letter that is undefined. * keyboard.c (read_key_sequence): If an upper case letter is undefined, and corresponding lower case letter is defined, use the lower case letter instead. * emacs.c: Delete all ALLIANT conditionals that used to save and restore _curbrk. Special code in crt0.c now handles this. * crt0.c [ISI68K]: Assembler code to put a .word 0 after _start. Include the dummy arg `ignore' in start1. * crt0.c [orion/pyramid/celerity]: ALLIANT now uses this case, but with some special code to hack _curbrk on first startup. * m-alliant2.h: File deleted. Use m-alliant.h for version 2. * m-alliant1.h: Don't look for ALLIANT2 to be defined. Now ALLIANT1 is defined for version 1 and not for version 2. Define NO_ARG_ARRAY only for version 1. Define START_FILES so GNU crt0.c gets used. Remove definition of TEXT_START (safe since GNU crt0.c is used). Add to ADJUST_EXEC_HEADER something to set unexec_text_start.

Thu Feb 19 15:28:01 1987 Richard Mlynarik (mly at prep) * lisp.h: Add type Lisp_Window_Configuration, delete Lisp_Temp_Vector. A window configuration is a Lisp_Vector-like object. Add decls for F{set,current}_window_configuration. * window.c (F{set,current}_window_configuration): New lisp-callable functions which do the guts of Fsave_window_excursion. Also fixed a bug in which point was not being restored in buffer currrent at end of save-window-excursion and that buffer was not current when the config was recorded (It is supposed to not be restored if it was current at the start) * alloc.c (mark_object): Add case for Lisp_Window_Configuration; remove code for Lisp_Temp_vector. * window.c, window.h: Rename Fshow_buffer Fset_window_buffer (which was previously the synonym in subr.el) * keyboard.c, minibuf.c: Window configuration caller changes. * print.c (print): Understand Lisp_Window_Configuration's. Print a disturbing message if encounter an illegal dtp -- perhaps this should core-dump? Tue Feb 17 13:13:13 1987 Richard Mlynarik (mly at prep) * dired.c (Ffile_attributes): Use make_number. (XINT doesn't work on LHS of assignment) Tue Feb 17 04:02:04 1987 Richard M. Stallman (rms at prep) * doc.c (get_doc_string, Fsnarf_documentation): In vms4.4, avoid system bug by using sys_translate_unix to translate filename to VMS format before opening. Mon Feb 16 05:20:41 1987 Richard M. Stallman (rms at prep) * crt0.c: Don't define `environ' if DONT_NEED_ENVIRON is defined. * m-elxsi.h: Define DONT_NEED_ENVIRON Define C_DEBUG_SWITCH as -O since there is no debugger.

Stallman (rms at prep) * s-bsd4-2.h: Make defns of BSD and BSD4_2 conditional. Fri Feb 13 12:27:05 1987 Richard M. Stallman (rms at prep) * process.c: TCP connection feature from markl@jhereg.lcs.mit.edu. Uses a process-object to represent a connection. childp field is now Qt for a real subprocess, or a hostname string for a tcp connection. NETCONN_P checks this. Status strings "open" and "closed" replace "run" and "exit" for tcp connections only. New function Fopen_network_stream. * dired.c (Ffile_attributes): Use XINT to store the inode #. It can be out of range for integers. Thu Feb 12 11:55:11 1987 Richard M. Stallman (rms at prep) * xdisp.c (try_window): Fix paren errer in checking hpos against hscroll. This caused window_end_pos to be wrong when there was hscroll. * xdisp.c (display_text_line): Move code that inserts `$' at bol for hscroll, so that its alteration of p1 does not interfere with setting point_hpos. Use lastpos instead of pos in that code. Make lastpos be accurate in all cases including when there is truncation. * xdisp.c (display_string): mincol==-1 means no minimum. * xdisp.c (display_text_line): Use -1 for mincol of minibuf promp. Wed Feb 11 19:30:54 1987 Richard M. Stallman (rms at prep) * Version 18.37 released. * data.c (Fmake_local_variable, Fmake_variable_buffer_local): Get error if arg is t or nil. Doc improvements.

Stallman (rms at prep) * process.c (change_msgs): Save/restore selected buffer only over simple insertions, and over one such at a time. Don't save it across sentinel invocations. Sun Feb 8 09:37:06 1987 Richard M. Stallman (rms at prep) * tparam.c (tparam): Supply code for NO_ARG_ARRAY case. * window.c, minibuf.c, window.h: Rename minibuf_scroll_window to Vminibuf_scroll_window. Make it a Lisp variable. * window.c (Fscroll_other_window): Validate Vminibuf_scroll_window since user could store a non-window there. * window.c (temp_output_buffer_show): Call Vtemp_output_buffer_show_hook to do the work, if not nil. * window.c (Fminibuffer_window): New function. * print.c (print, syms_of_print): If print_escape_newlines is nonzero, print newlines in strings as \n. * minibuf.c (read_minibuf): Reduce arg to get_minibuf by 1. Thus, use *Minibuf-0* for outer-level minibuffers. * keyboard.c (command_loop_1): Pass 2nd arg to Fsit_for. * minibuf.c (temp_minibuf_message): Likewise. * dispnew.c (Fsit_for): 2nd arg non-nil means don't redisplay. * s-vms.h: Don't define VMS4_0, VMS4_2 or VMS4_4. * s-vms4-[024].h: New files that include s-vms.h and also define VMS4_0 or VMS4_2 or VMS4_4. * vmspaths.h: Remove `/emacs' from all paths, to go with a change in emacs.com that includes that path segment in emacs_library. * term.c (term_init): Different message on VMS for invalid termtype. * alloc.c (Fgarbage_collect): After GC, clear marks in the dummy buffers buffer_defaults and buffer_local_symbols. Sat Feb 7 20:12:23 1987 Richard M. Stallman (rms at prep) * window.c (Fnext_window): Restore old meaning of t as 2nd arg: count minibuffer window even if not active. Non-t-non-nil as 2nd arg means never count minibuffer window. * window.c (window_loop): Rewrite to work the old way. The new way did not work when deleting windows. Thu Feb 5 01:56:33 1987 Richard M. Stallman (rms at prep) * m-sequent.h: Undef old definition of KERNEL_FILE so no warning. * process.c (read_process_output): Don't restore selected buffer after filter; sometimes setting buffer is useful in filter functions. Mon Feb 2 23:26:46 1987 Richard M. Stallman (rms at prep) * keyboard.c (kbd-buffer_store_char): Fix paren error. Sat Jan 31 11:06:24 1987 Richard M. Stallman (rms at prep) * window.c (window_loop): Rewrite not to pass t as 2nd arg to Fnext_window by starting loop from the window after the minibuffer. This was sole use of the feature. * window.c (Fnext_window): Change meaning of t as 2nd arg. It now means to ignore the minibuffer even if it's active. Thu Jan 29 19:15:26 1987 Richard M. Stallman (rms at prep) * cmds.c (Fforward_line): Correct the returned value. Wed Jan 28 03:15:48 1987 Richard M. Stallman (rms at prep) * keyboard.c (kbd_buffer_store_char): Ignore meta bit while checking for C-g, if meta-flag is clear. * unexec.c (make_hdr): typo `bas_start'. * sysdep.c: Declare errno explicitly since errno.h may fail to. * fileio.c (Fwrite_region): Move the fstat after the fsync. [Note: the above sentence was incorrect; actually the fstat had been after and was moved *before* the fsync. -- RMS, Mar 3.] Avoids RFS lossage with fsync (maybe). * s-rtu.h: Define NLIST_STRUCT and LDAV_SYMBOL. * m-masscomp.h: Check machine type to choose between C_ALLOCA and HAVE_ALLOCA. Tue Jan 27 11:09:47 1987 Richard Mlynarik (mly at prep) * window.c (change_window_height): Validate window_min_height. Mon Jan 26 13:27:23 1987 Richard M. Stallman (rms at prep) * m-ibmrt.h: LOAD_AVE_TYPE now double. Now both operating systems for RT now supported. * fileio.c (Fsubstitute_in_file_name): Delete everything thru last /~ or // in file name. * sysdep.c (select): If no subprocesses, make `child_changed' local and initialized to 0. * xdisp.c (display_string): If TRUNCATE is 0, display all the way to window edge; don't stop one column short. Sat Jan 24 14:36:26 1987 Richard M. Stallman (rms at prep) * unexec.c (make_hdr): New var `bss_end' holds end-of-bss address. This simplifies computation of bss size while keeping it from being negative. Fri Jan 23 08:56:56 1987 Richard Mlynarik (mly at prep) * fileio.c (Fexpand_file_name): Have to do checks for "//" "/~" etc even if filename is non-absolute, otherwise things like "~user1/~user2" aren't expanded correctly (was getting "/u/user1/~user2" instead of "/u/user2") * doc.c (Fsubstitute_command_keys): Doc fix. * m-stride.h: Fixes from bruce@stride.com Thu Jan 22 00:01:01 1987 Richard M. Stallman (rms at prep) * eval.c (Feval, apply_lambda): When protecting a vector of evaluated arguments, across the loop that evals them, always set gcproN.nvars to the number of args evalled so far, since the rest of the vector elements are still garbage. Wed Jan 21 00:36:04 1987 Richard M. Stallman (rms at prep) * Version 18.36 released. Wed Jan 21 00:36:04 1987 Richard M. Stallman (rms at prep) * term.c (write_chars): If we find N identical chars and that is too few for a Repeat operation, don't consider the last N-1, last N-2, ... of those chars. * dispnew.c (update_line): Fill old line with spaces to screen_width - 1 if it is highlighted (just like new line). * bytecode.c (Fbytecode): Include bytecode pc value in stack over/underflow errors Tue Jan 20 20:46:34 1987 Richard M. Stallman (rms at prep) * lread.c (defvar_lisp_nopro): New fn like defvar_lisp but doesn't call staticpro. * lisp.h (DEFVAR_LISP_NOPRO): New macro to call that function. * buffer.c (syms_of_buffer): Use DEFVAR_LISP_NOPRO to define variables that live in buffer_defaults. * buffer.c (init_buffer_once): tab_width was being assigned two different flag bits. * keyboard.c: #undef SIGIO if there's no FIONREAD. Mon Jan 19 22:01:35 1987 Richard M. Stallman (rms at prep) * indent.c (compute_motion): IBMRT needs HPOS defined like celerity.

Stallman (rms at prep) * fns.c (Fconcat): doc fix. Thu Jan 15 09:13:20 1987 Richard Mlynarik (mly at prep) * keyboard.c (last_command): doc fix Tue Jan 13 16:27:43 1987 Richard M. Stallman (rms at prep) * process.c (create_process): Cast value of `signal' to insulate from * sysdep.c (sys_suspend, select): changed value type in sysV.3. Mon Jan 12 12:33:42 1987 Richard M. Stallman (rms at prep) * sysdep.c (reset_sys_modes): Use TCSETAW to restore tty state. On BSD, define TCSETAW to be TIOCSETN (so no change here on BSD). * callproc.c (init_callproc): Don't get environment as strings when dumping Emacs. Mon Jan 12 00:19:26 1987 Richard Mlynarik (mly at prep) * lread.c (Fload, load_unwind): load_in_progress must be a counter, not a flag since `load' may be called recursively. * lread.c (openp): If PATH contains non-absolute element (such as ".") expand against bf_cur->directory. * filemode.c (ftypelet): Understand (and return) more different file-types (stat->st_mode's) This makes Ffile_attributes more winning. * filelock.c (current_lock_file_owner_1): Always close the fd even if get an error reading!!! Sun Jan 11 20:34:43 1987 Richard Mlynarik (mly at prep) * fileio.c (Fsubstitute_in_file_name, Fread_file_name_internal): `Quote' "$" as "$$" This doesn't break any existing code, since "$$" used to get an error, and wins by providing the user a way to specify filenames containing the character "$" * fileio.c (Fsubstitute_in_file_name): Allow substituting zero-length env vars. Sat Jan 10 10:52:46 1987 Richard M. Stallman (rms at prep) * termcap.c (tgetent): Fix syntax errors in VMS-only code.

Thu Jan 8 11:45:51 1987 Richard Mlynarik (mly at prep) * xfns.c (Fx_get_default): Return nil, not "" on non-existent option, as documented. Don't randomly and unnecessarily malloc (and then not free) * process.c (init_process): Look at extern var initialized rather than having arg passed. * emacs.c (main): Dike out the code which hacked the "-nx" option as synonymous with "-nw" if HAVE_X_WINDOWS -- this code was never distributed earlier, so there was no need to retain a compatibility kludge. Thu Jan 8 00:43:04 1987 Richard M. Stallman (rms at prep) * search.c (Freplace_match): Change declaration `char' to `int'. Declaring a scalar variable `char' is nearly always wrong and breaks most compilers. Wed Jan 7 13:52:12 1987 Richard M.

Tue Jan 6 14:29:55 1987 Richard Mlynarik (mly at prep) * keyboard.c (kbd_buffer_{read,store}_char): Look at MetaFlag when reading char out of buffer rather than storing into it so that buffer-local meta-flag works correctly. Tue Jan 6 13:53:52 1987 Richard M. Stallman (rms at prep) * syntax.c (Fchar_syntax, Fmodify_syntax_entry): Mask specified char to 8 bits before indexing syntax table.

Some functions were depending on the fact that all extern declarations are effectively at top level in pcc. * buffer.c (Fbuffer_start_undo): Get error right if non-ex buf spec'd. * indent.c (several): Fix range checks on tab_width: replace && with ||. Thu Jan 1 17:08:59 1987 Richard Mlynarik (mly at prep) * indent.c (Fcurrent_column, Fmove_to_column): Doc. * window.c (Fwindow_edges): Doc. * process.c, callproc.c: Make MAINTAIN_ENVIRONMENT stuff work yet again. Clean up calling sequence of child_setup. Wed Dec 31 04:07:42 1986 Richard M. Stallman (rms at prep) * search.c (search_command): abort before setting point if new point value is out of range. * buffer.c (Fbuffer_enable_undo): New function. Fri Dec 26 17:47:49 1986 Richard M. Stallman (rms at prep) * casefiddle.c (casify_region): Don't upcase within word for CASE_CAPITALIZE_UP. Wed Dec 24 18:13:18 1986 Richard M. Stallman (rms at prep) * window.c (save_window_save_1): Don't make windows for start, pointm and mark fields of windows without buffers; just store nil there. Also store nil in start_at_line_beg field (was uninitialized and that caused crash in GC). * window.c (all functions): Add register declarations. * window.c (Fsave_window_excursion): Don't gcpro the saved window status. The specpdl does it. Tue Dec 23 16:50:06 1986 Richard M. Stallman (rms at prep) * search.c: static_BM_tab should not be initialized. Mon Dec 22 02:03:51 1986 Richard M. Stallman (rms at prep) * term.c (term_init): Default Wcm.cm_tab to 0 if no `ta' string. * fns.c: MASSCOMP_REGISTER_BUG => MASSC_REGISTER_BUG * fns.c (Fnth): Moved from subr.el. * keymap.c (Fcopy_keymap): Moved from subr.el. * xdisp.c: Delete this_line_hpos; last dispnew change ends need for it, and it was causing incorrect positioning after direct_output_for_self_insert. * fns.c: Avoid warning if param.h defines BSD4_3. * dispnew.c (update_screen): Don't actually alter cursX and cursY when putting cursor in echo area. Sun Dec 21 00:48:00 1986 Richard M. Stallman (rms at prep) * window.h: New window field window_end_valid. window_end_pos is now always positive; validity info is in window_end_valid, which is t for valid and nil for not. * xdisp.c: Changed all uses of window_end_pos to use window_end_valid appropriately as well. * process.c (wait_reading_process_input): read_kbd is now a process pointer to wait for input from one process. Return immediately if that process is not running. * process.c (Faccept_process_output): Pass process pointer to wait_reading_process_input. Sat Dec 20 23:55:55 1986 Richard Mlynarik (mly at prep) * keyboard.c (Fsuspend_emacs): If `suspend-emacs-hook' returns t don't suspend -- assume the hook did the equivalent of `suspending' for us (including calling suspend-resume-hook if necessary.) Otherwise, call sys_suspend and so forth normally. Sat Dec 20 22:42:52 1986 Richard M. Stallman (rms at prep) * buffer.c (Frename_buffer): If have auto save file but no visited file, call rename-auto-save-file (a Lisp function). * buffer.c: add lots of register declarations. (list_buffers_1): combine local `mode' with `tail'. Sat Dec 20 15:47:01 1986 Richard Mlynarik (mly at prep) * xdisp.c (DoDsp and this_line_*): Rename this_line_hpos -> this_line_start_hpos. New variable this_line_hpos is cached horizontal position on screen of point. Make this_line_* static variables. In DoDsp, rearrange the tests to see whether to use cached line info to be a little faster. Fix some bugs in which cursX and cursY might not be updated correctly when using cached info (needed to add this_line_hpos variable to do this correctly) (Added unnecessary gotos and label `cancel' for added readability) * fns.c (Fy_or_n_p): Move cursor to start of line after reading answer so user knows emacs is proceeding. (Like after minibuffer exits) * dispnew.c (Fopen_termscript): Arg of nil means to close current termscript file (if any) * keymap.c (Fwhere_is_internal): Doc fix. * indent.c, search.c, xdisp.c: All callers of ScanBf were searching for '\n' Rename this function find_next_newline and drop first arg. * indent.c (Fvertical_motion): Doc string addition. * keyboard.c (EchoThem): Test for echo_keystrokes > 0, rather than echo_keystrokes != 0 * keyboard.c (get_char, read_key_sequence): Echo immediately if cursor_in_echo_area, otherwise can have the confusing situation of the cursor appearing at the start of the echo area, but not have any echo appear until one second later. Wed Dec 17 12:27:01 1986 Richard M. Stallman (rms at prep) * editfns.c: Add register declarations and a few vars for cses. * editfns.c (Fchar_equal): Avoid indexing downcase_table with numbers larger than 0xff. Tue Dec 16 01:05:16 1986 Richard M. Stallman (rms at prep) * alloc.c: New garbage collection technique for strings. Strings that have string blocks individually allocated are called "large strings". Other strings are called "small". The string blocks for small strings are now chained both ways and there is a pointer to the oldest one of them in `first_string_block'. The string blocks for large strings are chained only from the latest to the oldest, and the latest is in `large_string_blocks'. Garbage collection starts by setting MARKBIT in the `size' of each large string. This allows mark_object to distinguish them. MARKBIT in string sizes is cleared by gc_sweep. Large strings are freed individually by GC, like vectors. Those in use are marked with ARRAY_MARK_FLAG in the `size' field. Small strings are relocated, compressing them within their string blocks. mark_object puts all slots that point at a string onto a chain which runs from the string's `size' field, through all the slots that used to point at the string. The end of the chain is shown by a number that is small enough to be a small string's length. This new technique avoids calling malloc during GC. Thus, there is no danger of fatal error on exhausting memory. Also, space needed for strings is cut in half. The new technique introduces a potential for bugs, however. If any slot is marked twice--for example, if it is GCPRO'd twice by different functions--and it contains a string, the ref chain of the string may become garbled. Sometimes it will still work! This is because a slot that's part of a string's ref chain will look like a Lisp_Int if the next thing in the chain is malloc'd memory. But this will not win if the next thing in the chain is a stack slot, or if malloc'd data lives high up in memory. To avoid this problem, MARKBIT is used in stack slots to prevent double marking. * bytecode.c (Fbytecode): Adjustment of gcpro1.nvars before call to Ffuncall was off by one. * alloc.c (make_uninit_string): make_zero_string renamed as this and no longer zeros the contents. * alloc.c (Fmake_string): initialize string contents. * alloc.c (struct string_block): Now chained both ways thru `next' and `prev' fields. `first_string_block' exists. Strings with individual string blocks are now called "large" and these string blocks go in a separate chain which starts from `large_string_blocks' and runs via `prev' fields only. * alloc.c: Stop using clear_marks. Make gc_sweep clear the marks on all live objects. * alloc.c (malloc_warning, Fgarbage_collect): Eliminate mechanism that defers malloc warnings during GC, since GC no longer calls malloc. * fns.c: Fding requires an arg; pass Qnil. * m-alliant.h: define TEXT_START as 0x1000. Don't define LIBS_STANDARD; the default (sharable) library is said to work now. * alloc.c (mark_object): Now pass address of slot being marked. mark_object itself can alter the slot when necessary. It now returns no value. All callers changed to pass the address. mark_object can now ignore the mark bit if it's set in the slot. Callers need no longer make a copy in which mark bit is clear. mark_object can clear the mark bit so these callers must still set the mark bit again after calling mark_object on such slots. Mon Dec 15 21:25:18 1986 Richard M. Stallman (rms at prep) * process.c (create_process): TIOCNOTTY needs no 3rd arg after all. * sysdep.c (set_exclusive_use): ditto for FIOCLEX. * emacs.c (Fdump_emacs): [ALLIANT] Copy _curbrk into save_curbrk, not vice versa. Sat Dec 13 02:32:47 1986 Richard M. Stallman (rms at prep) * sysdep.c (flush_pending_output): 3rd arg to TIOCFLUSH now is address of word containing zero. It matters. * editfns.c (Fformat): Fix another error in previous bug. Fri Dec 12 10:34:02 1986 Richard M. Stallman (rms at prep) * Version 18.33 released. * data.c: Add many register declarations. * editfns.c (Fformat): Last change left `n' one too small. Thu Dec 11 17:43:44 1986 Richard M. Stallman (rms at prep) * keyboard.c (Fsuspend_emacs): Pass no args to the suspend-resume-hook. Also call a new hook, `suspend-hook', before suspending. * search.c (search_buffer): In inner loop of BM search, decide dynamically whether signed or unsigned comparison of p_limit vs cursor will give the right results and use the kind that will work. Thu Dec 11 12:17:31 1986 Richard Mlynarik (mly at prep) * emacs.c, dispnew.c: Rename inhibit_x_windows inhibit_window_system. Understand "-nw" command-line option.

Sat Dec 6 13:17:57 1986 Richard M. Stallman (rms at prep) * Version 18.32 released. * process.c ({read,handle}_process_output): Combine handle_process_output into read_process_output. Check for case where read returns -1. Fri Dec 5 02:30:37 1986 Richard M. Stallman (rms at prep) * process.c (read_process_output): Read only one buffer worth and return without trying to read more. It used to loop until all output was gobbled. Now some callers do this loop but not all of them. * process.c (change_msgs): Call read_process_output repeatedly until it returns 0 (no chars were read). * term.c (write_chars): loop counting repeated chars leaves p at second nonrepeated char. Decrement p after the loop. * process.c (create_process): Use set_exclusive_use; don't use FIOCLEX directly. * sysdep.c (flush_pending_output): Pass a valid address as third arg to TIOCFLUSH, just in case. * sysdep.c (set_exclusive_use): Likewise, with FIOCLEX. * process.c (create_process): Likewise, with TIOCNOTTY. * xfns.c (XCleanUp): Pass Qt to Fdo_auto_save. * xfns.c (Fx_rubber_band): Set screen_garbaged. * doc.c (Fsubstitute_command_keys): Use Fwhere_is_internal instead of where_is_in_buffer. New construct = means use value of MAPVAR as local map when calling Fwhere_is_internal. * keymap.c (Fwhere_is_internal, where_is_in_buffer): Combine the two functions. This adds two arguments to Fwhere_is_internal: KEYMAP and FIRSTONLY. To get the old behavior, KEYMAP must be (current-local-map). Therefore, KEYMAP is a mandatory operand for Lisp callers. * keymap.c (Fwhere_is): Pass new args to Fwhere_is_internal. * keymap.c (apropos1): Call Fwhere_is_internal instead of where_is_in_buffer. * search.c (Freplace_match): Check type of first arg. * abbrev.c (Fexpand_abbrev): For abbrev with hook, run the hook in addition to (and following) insertion of the expansion in the usual way. * editfns.c (Fformat): [MLY] Compute number of args needed by format string; then convert args from Lisp_Object to int or char *, defaulting any not specified. Don't GCPRO; should not be needed since eval is not called. * editfns.c (format1): Args are ints or char *'s, not Lisp_Objects. Call them ints. Thu Dec 4 17:54:21 1986 Richard Mlynarik (mly at prep) * xfns.c (Fx_debug): Return Lisp_Object Mon Dec 1 16:10:38 1986 Richard Mlynarik (mly at prep) * xfns.c (Fx_set_font): Don't die if font is "" (I believe this to be an X bug) Also, add interactive specs for Fx_set_(internal_)border_width. * lread.c (oblookup): Don't core-dump if data in obarray is invalid Mon Dec 1 08:32:13 1986 Richard M. Stallman (rms at prep) * m-att3b.h: on 3b2, 3b5 and 3b15, #define C_OPTIMIZE_SWITCH null since -O triggers compiler bug affecting push_key_description. Fri Nov 28 14:02:07 1986 Richard Mlynarik (mly at prep) * keyboard.c (read_key_sequence): Delay setting up the local vars pointing to keymaps until a character has been read. This is in order that a change of keymap `behind our back' (eg due to a subprocesses action) will be seen. * xterm.c: Typo. Wed Nov 26 04:18:46 1986 Richard M. Stallman (rms at prep) * sysdep.c (get_system_name): Eliminate internal static var in USG case. * lisp.h: New case testing and conversion macros UPPERCASEP, LOWERCASEP, NOCASEP, UPCASE, DOWNCASE. They all work from downcase_table. * casefiddle.c (casify_object, casify_region): Use those macros. Create an enum type for the flags and change the flag names to avoid conflict with the macros. * abbrev.c (Fexpand_abbrev): Use those macros. * editfns.c (init_editfns): * fns.c (y-or-n-p): * keymap.c (access_keymap): * fileio.c (report_file_error): * process.c (change_msgs): * search.c (Freplace_match): Use upcase_initials_region insead of duplicating it. * keyboard.c (Frecursive_edit): If not the top-level edit, specbind standard-output and standard-input to t. * keyboard.c (command_loop_1): Don't set those two vars. This avoids clobbering them permanently when minibuffer is used. Tue Nov 25 02:52:36 1986 Richard M. Stallman (rms at prep) * callproc.c (child_setup): New arg `envlen' is length of the list Vprocess_extra_environment. This list's elements (strings) are put at the front of the environment for the other program. * callproc.c (Fcall_process): Some rearrangement of local variables for more register decls. Compute and pass `envlen' arg to child_setup. * process.c (create_process): Compute and pass `envlen' arg to child_setup. * xterm.c (x_term_init): Don't call XPopUpWindow at all. Leave it for the term-setup-hook (see lisp/term/x-win.el). * keyboard.c (syms_of_keyboard): Delete defsubr for usg-suspend-emacs. * fns.c, m-masscomp.h: Rename MASSCOMP_REGISTER_BUG to MASSC_REGISTER_BUG to avoid shortnames confusion on V.0. * dispnew.c (direct_output_for_{self_insert,forward_char}): These functions now return 0 if did nothing or 1 if did display. * keyboard.c (command_loop_1): Notice the returned values. * window.c (change_window_height): Add new variable delta1 so no need to use delta for two different things. Making window bigger to equal its parent's size used to crash. Fix it by different way of computing delta1 in that case. Move some variable decls to inner blocks and add "register". Mon Nov 24 14:09:52 1986 Richard M. Stallman (rms at prep) * buffer.h: `modtime' field = 0 now means no info on visited file. Nonexistent visited file now represented by -1. * fileio.c (Fverify_visited_file_modtime): Adjust for changed meaning of `modtime'. * fileio.c (Finsert_file_contents): If visiting and file doesn't exist, finish visiting (updating various buffer slots) before getting error, and set modtime to -1. * bytecode.c (Fbytecode): Rarrange all the Bvarref cases to share most of the code. Likewise for Bvarset, Bvarbind and Bunbind cases. Makes it smaller and makes all Bvarrefs use the fast inline code. * keymap.c (Fdefine_key, Flookup_key): Regard chars 0200 and up as equivalent to 2 char sequences starting with meta_prefix_char. * search.c (search_buffer and callers): Complete rewrite from king@kestrel using simplified Boyer-Moore algorithm. Meaning of returned value changed. * search.c (bcmp_buffer_translated): No longer used; deleted. * search.c (ScanBf, scan_buffer): complete rewrite of ScanBf and nearly all is now in scan_buffer, a new function. * cmds.c (Fforward_line): Complete rewrite; now calls scan_buffer. * search.c (Fscan_buffer): Delete this. * bytecode.c (Fbytecode): Just get error if Bscan_buffer is used. * ymakefile: Rename TEXT_START_ADDR to LD_TEXT_START_ADDR to avoid shortname trouble (ymakefile is processed thru the system's cpp). * sysdep.c (init_sys_modes): Change #ifdef USG to #ifdef _IOFBF around the call to setvbuf. * sysdep.c (bcopy): declare it to return int so that a forward declaration is not needed so there is no problem defining it as a macro. * fileio.c (Fwrite_region): Don't try fsync on 4.1bsd. Sun Nov 23 00:04:19 1986 Richard M. Stallman (rms at prep) * eval.c (record_unwind_protect, specbind, unbind_to, Funbind_protect): struct specbind now has a new slot `func'. An internal unwind-protect stores the C function address there; else it's 0. Lisp_Internal_Function data type no longer used. Result is no more dependency on where in the address space function addresses are found. * xterm.c (x_term_init): Better message if server does not respond. * version 18.31 released. * xterm.c, xfns.c (Vxterm1): Lisp var `xterm' now points at Vxterm1, which is initialized like Vxterm but never examined. * xterm.c (XTread_socket): Use C-x C-@ to indicate mouse click. Sat Nov 22 02:21:56 1986 Richard M. Stallman (rms at prep) * bytecode.c (Fbytecode): Turn on immediate_quit for Bnth loop. * keymap.c (Fcurrent_global_map): New function that returns the current global map. Fri Nov 21 15:42:05 1986 Richard M. Stallman (rms at prep) * emacs.c (main, Fdump_emacs): [ALLIANT] save _curbrk before dumping and restore when starting dumped Emacs. * process.c (wait_reading_process_input): [ALLIANT] if select returns with EFAULT, just set Available = 0. [always] copy errno right after the select and check the copy in case another system call could alter it in between. * m-alliant.h, m-mg1.h: New machines supported. * ymakefile: Make START_FILES a preprocesser variable and don't change it if already defined. * m-gould.h: Move special gould value of START_FILES here. * fileio.c (syms_of_fileio): Define variable vms-stmlf-recfm. * sysdep.c (sys_creat): If vms_stmlf_recfm is nonzero, create new files with rfm=stmlf. Thu Nov 20 17:07:14 1986 Richard M. Stallman (rms at prep) * eval.c (unbind_catch): Don't ref thru handlerlist if null. * keyboard.c (Fusg_suspend_emacs): Delete this. * sysdep.c (sys_suspend): Put in USG_JOBCTRL method of suspending with ptrace. Wed Nov 19 06:45:23 1986 Richard M. Stallman (rms at prep) * xterm.c (x_term_init): Delete attempt to set up a handler for SIGIO. This was normally overridden in init_keyboard so it didn't matter; but this handler is invalid, so it crashed if it ever did get called. * indent.c (compute_motion): Fix screwy #if celerity || ATT3B which is invalid. Tue Nov 18 17:59:57 1986 Richard M. Stallman (rms at prep) * keyboard.c (command_loop_1): Must check to reselect buffer and flush minibuf message before trying fast_read_single_key. Else have lossage typing printing chars when minibuf message is displayed. * keyboard.c (Fsuspend_emacs): Execute suspend-resume-hook value on resumption. * lisp.h: Make initialized global. * data.c (init_data): Undo last change; not needed now. Tue Nov 18 15:19:06 1986 Richard Mlynarik (mly at prep) * emacs.c (main): Giving `inhibit_x_windows' an initialisation loses; do it explicitly. * xfns.c (Fx_rubber_band): Make interactive. Tue Nov 18 14:40:04 1986 Richard M. Stallman (rms at prep) * dispnew.c (window_change_signal): New function to handle SIGWINCH, defined only if SIGWINCH is. Turned on in init_display if CANNOT_DUMP or if initialized. * data.c (init_data), editfns.c (init_editfns): Test initialized, not Vpurify_flag. Use explicit conditionals to avoid the test when CANNOT_DUMP. Mon Nov 17 00:19:06 1986 Richard M. Stallman (rms at prep) * buffer.c (Ferase_buffer): Zero the buffer's save_length. Future text after erase is unrelated to past text so should not suspend auto saving if future text is smaller. * buffer.c (init_buffer_once): Was passing entire structure to bzero; now pass address. * fns.c: Prevent warning in 4.3 where param.h does #define BSD Sun Nov 16 12:56:21 1986 Richard M. Stallman (rms at prep) * dispnew.c (init_display): Set window-system to symbol x, not "X". * dispnew.c (syms_of_dispnew): Initialize window-system to nil. * xfns.c (grey_p): Insert missing commas. * emacs.c (main): Fix typo "ihhibit_x_windows". * xterm.c (x_term_init): Delay calling XPopUpWindow till after Vxterm is set. Also must include lisp.h. Also always set Vxterm if CANNOT_DUMP. * xfns.c, xterm.c: Include signal.h before xterm.h because on 4.3 both of them define sigmask and only xterm.h considers the case that it is already defined. * buffer.h: Add BufferSafeCeiling and BufferSafeFloor. * process.c (Fprocess_send_eof): Now has conditional on DID_REMOTE, which is defined if TIOCREMOTE is actually used. Sat Nov 15 00:53:26 1986 Richard M. Stallman (rms at prep) * Emacs version 18.30 * * xdisp.c (display_string): Change minwidth and maxwidth args to mincol and maxcol: minimum and maximum absolute hpos to end at. Change all callers (all in xdisp). * xdisp.c (display_mode_element) Similar change of minwidth and maxwidth args. This permits considerable internal simplification and deletion of the function display_mode_element_1. * xdisp.c (decode_mode_spec): Flush unused arg minwidth. Change call (in display_mode_element). Fri Nov 14 12:52:51 1986 Richard M. Stallman (rms at prep) * process.c (create_process): Don't get a pty if the new variable Vprocess_connection_type is not t. This is the Lisp variable process-connection-type. Thu Nov 13 18:46:32 1986 Richard M. Stallman (rms at prep) * crt0.c: Rename GLOBAL_START_{DOT,NO_DOT} to {DOT,NODOT}_GLOBAL_START to avoid shortnames trouble. * m-vax.h, m-tahoe.h, m-sequent.h: same change. * m-att3b.h: Turn off #define VIRT_ADDR_VARIES (kk says no need for it). * keyboard.c (Fcommand_execute): Zero debug_on_next_call before running the command. Wed Nov 12 10:19:31 1986 Richard Mlynarik (mly at prep) * data.c (Fsequencep): (sequencep nil) => t * xdisp.c (display_string): Put a "|" at end of mode-lines of partial-width windows. * xdisp.c (various): mode-line-format %259 means to pad field to 259, but not to truncate it. (259 . ) also means to pad. (-259 . ) means to truncate to 259, but not to pad. [So (-259 . (259 . x)) means to format x -exactly- 259 chars wide.] * dispnew.c (Fding): Do not terminate macro-definition if given an argument (This is so things like asynchronous process notifications can beep but not screw) Mon Nov 10 16:32:08 1986 Richard M. Stallman (rms at prep) * fileio.c (Fset_file_modes): [APOLLO] must reset modtime after changing the modes. Mon Nov 10 10:57:54 1986 Richard Mlynarik (mly at prep) * buffer.c (init_buffer_once): There is no lisp variable corresponding to buffer-name Mon Nov 10 00:06:31 1986 Richard M. Stallman (rms at prep) * xdisp.c (display_string): Measure new line length from start of line body. Sun Nov 9 00:22:04 1986 Richard M. Stallman (rms at prep) * lread.c (oblookup, map_obarray): Do not use XFASTINT on `next' fields of symbols. Fix incorrect sense of test for end of bucket. * filelock.c (current_file_owner): Fix incorrect sense of test with `kill' for death of previous locker. * keyboard.c (get_char): Arg of -1 now means don't do redisplay. Rearrange conditionals so detect_input_pending is not called in certain cases. * keyboard.c (read_key_sequence): New arg nodisplay, nonzero means pass -1 to 1st call to get_char. * keyboard.c (command_loop_1): After a command that does direct screen updating, if buffer_shared is not more than 1, pass 1 for nodisplay to read_key_sequence. * minibuf.c (Fminibuffer_depth): New function returns value of MinibufDepth as a Lisp Int. * dired.c (Ffile_attributes): Return inode # as element 10. * dispnew.c (update_line): Fix bug that noop'd the attempt to let new explicit spaces match the implicit space past end of old line. Also do not ignore trailing spaces in a highlighted line; instead, give it more trailing spaces so it reaches the margin. Sat Nov 8 20:55:04 1986 Richard M. Stallman (rms at prep) * data.c (init_data): Don't call signal if purifying. * ymakefile: Stop using gould-sigvec.s. No longer needed now that signal really isn't called. * unexec.c: Eliminate gould-specific code to reinitialize gould-sigvec.s. Fri Nov 7 01:30:31 1986 Richard M. Stallman (rms at prep) * m-vax.h: Turn off NO_REMAP. * sysdep.c (end_of_{data,text}): Omit them if CANNOT_DUMP. * fileio.c (Fwrite_region): APOLLO is now like VMS in doing the stat after the close. * emacs.c (main): If APOLLO, don't call malloc_init. We use the system's malloc on the Apollo. * editfns.c (init_editfns): If CANNOT_DUMP, do all the work, regardless of Vpurify_flag. * alloc.c (mark_object): If not SWITCH_ENUM_BUG don't cast the switch quantity to int. * process.c (pty): [HPUX] Do TIOCREMOTE. * unexec.c (makehdr): Code to adjust, default and validate data_start and bss_start now common to COFF and non-COFF cases. * unexec.c (makehdr): Param SEGMENT_MASK controls rounding of memory-address of text-data boundary (default is pagemask). [COFF only] SECTION_ALIGNMENT controls rounding of file addresses of section beginnings; default is no rounding. [non-COFF] ADJUST_EXEC_HEADER is hook to be executed before filling in a_text, etc. of the header. With these parameters, all known machines can be handled with no special conditionals. * m-sun1.h, m-sun2.h, m-isi-ov.h: Define SEGMENT_MASK. * m-stride.h, m-nu.h, s-umax.h: Define SECTION_ALIGNMENT. * m-masscomp.h, m-gould.h, s-hpux.h: Define ADJUST_EXEC_HEADER. * m-gould.h: Define A_TEXT_OFFSET = sizeof (hdr) * unexec.c (makehdr): Remove ibmrt conditionals that adjusted a_text or equivalent, by just copying from the old file when NO_REMAP. * unexec.c (makehdr): Zero supplied as entry_address means copy it from the old file. * emacs.c (Fdump_emacs): Pass 0 as entry_address to unexec. * unexec.c (copy_text_and_data): Two fixes for A_TEXT_OFFSET case: Don't decrement `end', and remove (unconditionally) the lseek before writing the data segment. Thu Nov 6 10:01:52 1986 Richard M. Stallman (rms at prep) * keymap.c (apropos1): Use Fdocumentation_property, not Fget, for doc strings of variables. Wed Nov 5 18:47:41 1986 Richard Mlynarik (mly at prep) * m-att3b.h: #define TEXT_START 0 Wed Nov 5 12:42:38 1986 Richard M. Stallman (rms at prep) * alloc.c (Fcons, Fmake_symbol, Fmake_marker, gc_sweep): The free-list pointers in symbols, conses and markers are now C pointers cast as ints and stored in the XFASTINT. This may make faster code and in any case avoids problems with machines where access with XPNTR relocates the pointer. * lread.c (oblookup, map_obarray): Use XFASTINT when comparing a Lisp_Object against zero. * minibuf.c (read_minibuf): If noninteractive, print the prompt, since it won't be displayed in the normal way. In any case, pass Fread the string rather than a buffer when reading an s-expression. * auxdoc.c, callint.c, syntax.c, ymakefile: Copy fake-DEFUNs from auxdoc.c into comments preceding the real DEFUNs for the same functions. auxdoc.c is no longer in use. * fileio.c (Fread_file_name_internal): [VMS only] Return t if file name is null string. Tue Nov 4 14:00:34 1986 Richard M. Stallman (rms at prep) * buffer.c (Fget_buffer_create): For default-major-mode = nil case, use fundamental-mode if old buffer's mode name has a non-nil mode-class property. Requires creating Qmode_class to hold the symbol mode-class. * s-hpux.h: #undef HAVE_PTYS because of problems with scheme running as an inferior on a pty. jinx@prep requested this. * lread.c (check_obarray & its callers): eliminate 2nd arg. Also, don't confuse types int and Lisp_Object. If invalid value matches Vobarray, store a valid Vobarray. * editfns.c (Fformat): Don't use an initialization for tem since it is a Lisp_Object and that can be a struct. * minibuf.c (Ftry_completion, Fall_completions): Use XFASTINT when testing `bucket' for nonzero or setting it to zero. * callint.c (Fcall_interactively): If visargs[i] is nil, don't try to reference it as a string. * doc.c (FSnarf_dcumentation): Was assuming exec-path was a string. Fixed to use exec-directory instead, and to validate its data type first. Tue Nov 4 10:06:24 1986 Richard Mlynarik (mly at prep) * m-isi.h => m-isi-ov.h Tue Nov 4 09:08:52 1986 Richard M. Stallman (rms at prep) * buffer.c (init_buffer_once): Avoid casts from int to Lisp_Object (which would lose if NO_UNION_TYPE is not defined); use XFASTINT. Mon Nov 3 16:36:03 1986 Richard Mlynarik (mly at prep) * xterm.c (stufflines): Initialise signal mask. * xterm.h: Add definition of sigmask Sat Nov 1 00:02:40 1986 Richard Mlynarik (mly at prep) * m-sun3.h: #undef sun2 ? #define sun3 * termcap.c: Include Dave Genzel @ Unilogic's VMS termcap stuff. * termcap.c: #ifdef emacs ? #include config.h * fileio.c, fns.c, m-vax.h: Fixes for VMS cpp. (#undef foo -> #ifdef foo ? #undef foo) Fri Oct 31 23:35:29 1986 Richard Mlynarik (mly at prep) * vmsmakefile (new file) * crt0.c, unexec.c, m-isi.h (new file): Integrated Solutions 68k port. Thu Oct 30 01:08:45 1986 Richard Mlynarik (mly at prep) * m-vax.h (USG-only changes): #define NO_REMAP (I don't understand exactly why one needs to do this -- is there an unexec bug?) #define TEXT_START = 0, since C code can't access `start' symbol. * lisp.h, sysdep.c, indent.c, m-att3b.h: USG and att3bxxx changes from karl@ohio-state.arpa Define NO_REMAP, undefine LD_SWITCH_MACHINE * buffer.c (Fbuffer_local_variables): Return correct values when buffer is selected-buffer * keyboard.c (cmd_error): non-zero exit status on error. * filelock.c: Don't get MPV if buffer-file-name isn't a string or nil. Wed Oct 29 10:18:39 1986 Richard Mlynarik (mly at prep) * keymap.c (Flookup_key, Fdefine_key): Don't bomb on zero-length strings. * filelock.c (Ffile_locked_p): New function. * window.c (Fset_window_hscroll): Don't inhibit redisplay optimisations if hscroll is same. * ymakefile: rm ../etc/DOC to avoid make-docfile overwriting any files which were linked to it (unix sucks) Tue Oct 28 00:12:50 1986 Richard Mlynarik (mly at prep) * vmsmap.c, termcap.c, sysdep.c, config.h-dist: VMS changes from Sasaki * termcap.c (tgetent): Make sure `indirect' initialised. * xfns.c (grey_p and callers): New function to compensate for ugly chauvinistic American spelling. * keymap.c (describe_*): Don't mention keys in global map which are shadowed by local bindings * dispnew.c, sysdep.c, dired.c: Eschew ^#if.*defined (for VMS' sake) * keymap.c (Fkeymapp, Flookup_key): Add QUIT test. Mon Oct 27 18:46:08 1986 Richard Mlynarik (mly at prep) * callproc.c, fileio.c: VMS changes (make environ noshare, don't call fsync) Sun Oct 26 00:28:02 1986 Richard Mlynarik (mly at prep) * sysdep.c, unexec.c, ymakefile: Gould changes. (marick%cthulhu@gswd-vms.ARPA) * gould-sigvec.s: New file. * m-gould.h: New file (for utx/32 2.0 and above) Old file renamed m-ogould.h. See etc/MACHINES for more information. * unexec.c (make_hdr): Typo "#ifdef A_TXT_OFFSET" should be "A_TEXT_OFFSET" Wed Oct 22 19:06:41 1986 Richard Mlynarik (mly at prep) * keyboard.c, keymap.c: Move Fexecute_extended_command from keymap.c to keyboard.c rather than make kludgy static vars global. In Fexecute_extended_command record `(this-command-keys)' and `last-command' accurately. * emacs.c (main), dispnew.c (init_display): Add -nx flag, meaning to inhibit X windows and just run in the current virtual terminal. (Perhaps there should be a generic flag to disable any special window-system code) Add Vwindow_system variable. * search.c (Fstring_match): Do range-checking on `start' argument. Tue Oct 21 11:33:40 1986 Richard Mlynarik (mly at prep) * xterm.c, xfns.c (x_term_init, x_change_display): Share command code, and make that code use {request,unrequest,init}_sigio * term.c (init_display): Determine whether we are under X by whether DISPLAY env var is set, not by whether TERM is "xterm" * xterm.c (x_term_init): Remove (if (!initialized) ...) test. Set Vxterm directly, rather than calling setxterm (flush latter) * lread.c (various): Changes for when can't take XSYMBOL of 0 and to make check_obarray code work correctly. Mon Oct 20 18:05:16 1986 Richard Mlynarik (mly at prep) * m-stride.h, process.c, sysdep.c, unexec.c: Stride changes. Sat Oct 18 16:35:26 1986 Richard Mlynarik (mly at prep) * buffer.c: Made default-major-mode same as (default-value 'major-mode) to avoid user confusion. Fri Oct 17 01:51:40 1986 Richard Mlynarik (mly at prep) * cmd.c, process.c: Doc fixes from sjk * buffer.c (init_buffer_once): Do x = (Lisp_Object) 1 instead of (int) x = 1 for benefit of vms and pyramid compilers. * minibuf.c (Ftry_completion): Test (bucket), not (XSYMBOL (bucket)) since Lisp_Objects may not be able to be 0 on some implementations. * editfns.c (Fformat): Have to duplicate doprnt's work of decoding the format-string top ensure that don't die on (format "%s" 0) Also, use prin1-to-string to get PR for random objects * m-celerity.h: HAVE_ALLOCA Thu Oct 16 20:01:55 1986 Richard Mlynarik (mly at prep) * m-att3b.h: New file -- replaces m-3b20.h * alloca.c, fileio.c, indent.c, unexec.c, ymakefile: Bugs and fixes for att3b (and usg) Use a global static var rather than a local one to record the last block allocated by alloca. * fileio.c (Fverify_visited_file_modtime): If a formerly-nonexistent file has been created since we ``found'' it, say there is a discrepancy. Tue Oct 14 19:08:18 1986 Richard Mlynarik (mly at prep) * callint.c (Fprefix_numeric_value): Doc typo. * malloc.c, regex.c: Nuke "#if defined..." for VMS Sun Oct 12 00:02:50 1986 Richard Mlynarik (mly at prep) * xdisp.c (many functions): Rearrange the way in which the mode-line stuff is hacked: in particular, display_string doesn't have a special-case for %-escapes -- this is now all done in display_mode_element. This was necessary to make %M work correctly. Also, fix a few bugs (buffer-name truncation could cause core-dump) Dike out global-minor-modes. This wasn't actually being used by anything (due to a bug) and wasn't even being initialised! minor-mode-alist does what this thought it was doing. Sat Oct 11 15:45:35 1986 Richard Mlynarik (mly at prep) * doc.c (FSnarf_documentation): In CANNOT_DUMP case wasn't treating PATH_EXEC as a path -- now uses exec-path instead. * lisp.h: Get rid of #if defined... for benefit of vms Thu Oct 9 20:52:25 1986 Richard Mlynarik (mly at prep) * abbrev.c (Funexpand_abbrev): Preserve position of point. Tue Oct 7 00:08:00 1986 Richard Mlynarik (mly at prep) * s-hpux.h: #define HAVE_PTYS * alloca.c: Make some attempt to work in the USG case where "#define static" is done. * keyboard.c: #undef FIONREAD in HPUX (seems to be unimplemented or broken) The only reason this ever seemed to work was because of a bug in v17. * sysdep.c (child_setup_tty): HPUX was defaulting terminal speed to 300 baud. * alloca.s: New hp9000 C function calling sequence. * fileio.c (Fexpand_file_name): Fix bug in (expand-file-name ".." "/foo/") * callint.c (Fcall_interactively): Remove extreme weirdness of storing (int) "" where a Lisp_Object was expected (in visargs) Slighly more informative error message for bad interactive code letter. * abbrev.c (Funexpand_abbrev): Was deleting length of original text rather than length of expanded abbrev. * abbrev.c (Fexpand_abbrev): Add an Fundo_boundary so that undo works to unexpand abbrevs. Fri Oct 3 16:07:32 1986 Richard M. Stallman (rms at prep) * ymakefile: Make LIBS_STANDARD the last libs loaded. * xterm.c: Load sys/types.h explicitly if xterm.h doesn't do it. * keyboard.c (interrupt_signal): Delete suprious `)' in HAVE_X_WINDOWS case. Fri Oct 3 14:08:00 1986 Richard Mlynarik (mly at prep) * sysdep.c (sys_suspend -- fake suspend case) Missing comment */ terminator Thu Oct 2 21:43:35 1986 Richard Mlynarik (mly at prep) * search.c: There may be `holes' in regexp registers after a match: consider matching "z" against "\\(\\(xyzzy\\)\\|\\)\\(z\\)" -- then register 2 is unmatched, whilst registers 0, 1 and 3 have matches. Fix register-hacking code in Flooking_at, search_buffer, Fmatch_data, Fstore_match_data. * crt0.c: HP200 floating-point (sigh -- needed for load-average) * sysdep.c (HPUX perror): Should be "perror" not "_perror" -- communication foulup, sorry. Wed Oct 1 00:00:52 1986 Richard M. Stallman (rms at prep) * marker.c (Fcopy_marker): Was stupidly failing to put the new marker on the buffer's chain. Fix to go thru Fset_marker. This really does fix the crashes in GC. * sysdep.c (for HPUX): Define utimes and _perror as no-ops. * marker.c (Fset_marker): If attempt to set marker to point to a dead buffer, set it to point nowhere. * buffer.c (Fkill_buffer): Clear out the buffer's markers chain. * keyboard.c (interrupt_signal): Turn off the double-C-g feature when running under X windows. Mon Sep 29 03:44:28 1986 Richard M. Stallman (rms at prep) * search.c: search_regs elements are now the correct character numbers or string indices. 1 is not added when they are used; instead the values are corrected just after regex library returns. The loops to do this exit at the first -1 (unused register). * alloca.s: Convert HP9000 code to new assembler syntax. Rename flag hp9000s200 to hp9000. [mly] * crt0.c: Convert HP9000 code to new assembler syntax. [mly] * buffer.c (Fdelete_buffer_internal): Unused; deleted. * marker.c (unchain_marker): Dump core if first marker on buffers marker list does not have that buffer as its buffer. May help find bug where after GC a buffer's first marker was on the free list. * keyboard.c (cmd_error): In -batch, die after error message. * bytecode.c (Fbytecode): Open-code Bvarref with one-byte arg. * callproc.c (init_callproc): Use only first element of Vexec_path to make Vexec_directory. [mly] Sun Sep 28 19:21:37 1986 Richard M. Stallman (rms at prep) * data.c (Fsymbol_value): use assq_no_quit instead of Fassq. * fns.c (assq_no_quit): Like Fassq but never quits or gets errors. * keyboard.c (quit_throw_to_get_char): * eval.c (Fsignal): Call quit_error_check. * dispnew.c (quit_error_check): Dump core if DesiredScreen is not full of zeros. This is to catch the bug wherein DoDsp called from get_char died because DesiredScreen was full of lines already. Fri Sep 26 17:01:09 1986 Richard Mlynarik (mly at prep) * regex.c (re_match_2), search.c (various): The registers modified by re_{search,match}{,_2} now have start and end of -1 if that register was not used in the match found. Fmatch_data now returns a list of twice the number of registers -actually- used (including register 0, for the whole match) * process.c (Fwaiting_for_user_input_p): New function for use by process-filters and sentinels so they can determine if it might be an appropriate time to try to make some sort of asynchronous notification. Fri Sep 26 04:08:54 1986 Richard M. Stallman (rms at prep) * keymap.c (syms_of_keymap): Add missing defsubr for Fdefine_prefix_command, * abbrev.c (Fexpand_abbrev): Save original text of the abbrev in Vlast_abbrev_text. * abbrev.c (Funexpand_abbrev): Restore the original text. Thus expand and unexpand preserves case. Also, if there is no abbrev to unexpand, do nothing. * abbrev.c (syms_of_abbrev): Turn Lisp variables last-abbrev and last-abbrev-text back on. * abbrev.c (Flast_abbrev_expansion): Delete this function. Thu Sep 25 18:30:35 1986 Richard M. Stallman (rms at prep) * window.c (Fwindow_width): return a value one smaller for partial-width windows that contain a | border. * macros.c: Remove Fname_last_kbd_macro (moved to macros.el). Thu Sep 25 07:54:12 1986 Richard Mlynarik (mly at prep) * unexec.c: Include a.out.h before getpagesize.h, since EXEC_PAGESIZE may be defined in a.out.h * dispnew.c: Only define TIOCOUTQ as TCOUTQ if the latter as defined, so that ifdef conditionals on the former work as expected. * sysdep.c (sys_suspend): Needed to include buffer.h for getting cwd when doing a fake suspend. (for system v and other complete losers) Rather than doing that include (which tickled some cretin-compiler bugs) look up bf_cur->default_directory by Fsymbol_value (Qintern ("...")) Wed Sep 24 21:28:47 1986 Richard Mlynarik (mly at prep) * editfns.c (Fregion_beginning, Fregion_end): Share common code (this doesn't have to be so fast that the extra function-call could hurt) * editfns.c, window.c, callint.c, buffer.c: Don't allow bf_cur->mark to be nil. Instead, to indicate that the mark is not set, make the marker not point at anything. This simplifies life quite a lot. Add sanity checking in case user sets mark to point to different buffer (he could do this by side-effecting (marker-mark) stupidly) Change definition of marker-mark so that it returns a marker object which doesn't point anywhere when there is no mark, rather than nil. This is more useful. * editfns.c, bytecode.c. Move set-mark, mark to lisp code. * editfns.c (Fset_mark) Not interactive. Tue Sep 23 14:26:18 1986 Richard M. Stallman (rms at prep) * crt0.c, m-hp9000.h: rename hp9000s200 to hp9000. * m-hp9000.h: New name for m-hp200.h. * unexec.c (for hpux): define MY_ID from HP9000S200_ID if that exists; else use model.h. Sun Sep 21 18:48:48 1986 Richard M. Stallman (rms at prep) * search.c (search_buffer): Fix backwards condition in whether the translate table can be ignored. * process.c (Fprocess_send_string): Name of function for Lisp had a typo. * eval.c: When looping getting the function definitions of symbols, check for quit. * lisp.h: Restore old declaration of `getenv' since removing it causes warnings in many places. * minibuf.c (scmp): Return correct value. Sun Sep 21 18:12:45 1986 Richard Mlynarik (mly at prep) * editfns.c (Finsert_char): New function. There are a lot of places in lisp code which want to insert multiple copies of a constant char. This is a faster way of doing it, and doesn't cons (unlike (insert (make-string n c))) Sun Sep 21 15:33:20 1986 Richard M. Stallman (rms at prep) * process.c (make_process): Code to compute # elts in vector to make a Lisp_Process had several errors: Took size of pointer rather than of struct Lisp_Vector and had wrong sign compensating for first element. * fileio.c (directory_file_name): If arg is "/", return "/". Sat Sep 20 21:08:35 1986 Richard M. Stallman (rms at prep) * minibuf.c (Fdisplay_completion_list): New Lisp-callable function replaces minibuffer_completion_help_1, with a little new feature: elements of the completion list may be lists of two strings, and if so the two strings are printed in immediate succession. Fri Sep 19 13:06:39 1986 Richard Mlynarik (mly at prep) * minibuf.c (scmp and callers) Don't be fazed by '\0' in strings. * lisp.h, search.c, minibuf.c Use downcase_table Thu Sep 18 18:32:57 1986 Richard Mlynarik (mly at prep) * ymakefile, emacs.c, callproc.c, process.c, fns.c Install MAINTAIN_ENVIRONMENT conditional to call environ.c. Tue Sep 16 02:01:17 1986 Richard M. Stallman (rms at prep) * keymap.c (where_is_in_buffer): Fix bug in checking for shadowed keys: do Flookup_key only on local map, and ignore value if it is a number (that means key is locally undefined). Mon Sep 15 12:33:10 1986 Richard Mlynarik (mly at prep) * buffer.c (Fbury_buffer) Make this function interactive (bury current buffer) Do error-checking on arg. Mon Sep 15 00:47:34 1986 Richard M. Stallman (rms at prep) * emacs.c (main): Eliminate VMS -nl switch. Instead, `-map FILE' says to map data file FILE; no switch means don't map any file. Can call mapin_data directly since exact file name is given. * emacs.c (undump_emacs): Delete this. * emacs.c (main): Make it work to use more than one of the special switches (-batch, -t, -map). Sun Sep 14 17:15:37 1986 Richard M. Stallman (rms at prep) * Renamings for VMS. config.h.dist => config.h-dist paths.h.dist => paths.h-dist [ms]-*.*.h => [ms]-*-*.h s-usg5.2.2.h => s-usg5-2-2.h * Some new files for VMS. compile.com, link.com, precomp.com, ccom.com, testemacs.com, build.com are command files. temacs.opt is a linker control file. VMSBUILD gives info on how to use them. README describes what this directory is for. Sat Sep 13 20:13:11 1986 Richard M. Stallman (rms at prep) * sysdep.c (reset_sys_modes): Delete never-used VMS & SIGIO conditional. Call reset_sigio just once. No need to clear FASYNC here now that init_sigio makes sure it is clear in old_fcntl_modes. * eval.c (top_level_value, top_level_set): These are new names for Fglobal_value and Fglobal_set, which are no longer callable from Lisp. They are also commented out. Fri Sep 12 00:19:37 1986 Richard Mlynarik (mly at prep) * xfns.c (Fx_rebind_key) Fix typo. * mocklisp.c: Delete ml-substr. Move to mlsupport.el * buffer.c The real work of setting up mode_line_default is done in loaddefs.el. * lread.c, data.c, marker.c, window.c Flush the last callers of defalias. Flush defalias. (Use fsets in subr.el instead) Thu Sep 11 10:15:14 1986 Richard Mlynarik (mly at prep) * emacs.c (main) Under X, accept "-display" switch as synonym for "-d" * eval.c (spedcbind) Don't make Lisp_Buffer_Objfwd's buffer-local when just binding. (so now (let ((case-fold-search t))) doesn't force buffer-localness) However, setting a binding will still make it buffer-local. (ie (let ((case-fold-search t)) (setq case-fold-search t)) will cause case-fold-search be buffer-local even outside the let) * xfns.c Preserve studlycaps: "Gnuemacs" => "GNU Emacs" * Various Flush last users of LISTP => CONSP * buffer.h Make backed_up a Lisp_Object, since it is one! Make abbrev_table a magic-local-variable. * alloc.c (mark_buffer) Simplify, simplify. * buffer.h: Reorder elements of struct buffer so that Lisp_Object slots are contiguous from buffer.name through to the end of the buffer. All slots before buffer.name are not Lisp_Objects (except buffer.markers, which is gc-magic) Eliminate useless buffer.number slot. * buffer.c (Fbuffer_number): delete. Wed Sep 10 17:32:47 1986 Richard M. Stallman (rms at prep) * process.c (Fsend_{string,region}): rename as Fprocess_send... and change names of Lisp function. Old names now aliases in subr.el. Wed Sep 10 15:57:01 1986 Richard Mlynarik (mly at prep) * buffer.c New struct buffer_local_symbols. staticpro buffer_defaults, buffer_local_symbols. * lread.c (defvar_per_buffer) Hack buffer_local_symbols * buffer.c (Fbuffer_local_variables) (a) Fcopy_alist so don't return any shared list structure (b) Include names and values of Lisp_Buffer_Objfwd locals. * alloc.c (FGarbage_collect): Don't mark buffer_defaults specially, as it is now in staticvec * dired.c (Fdirectory_files): Optional third argument match is a regexp specifying to only return files whose names contain a match for that regexp. [eg ``(directory-files "/u2/emacs/" nil "\\`[^#]")''] Wed Sep 10 02:11:56 1986 Richard M. Stallman (rms at prep) * alloc.c (Fgarbage_collect): Use open code instead of Fnthcdr to avoid possibility of error. * lread.c (Fload, load_unwind): The Lisp_Internal_Stream now points to a word got with xmalloc and that points to the FILE. On Elxsi, the FILE address is not in the part of the address space that Lisp_Object pointers can reach. New way can't lose. Tue Sep 9 23:21:11 1986 Richard M. Stallman (rms at prep) * crt0.c: Add _start for elxsi. Sun Sep 7 12:07:46 1986 Richard Mlynarik (mly at prep) * minibuf.c (read_minibuf) gc-protect the saved data! I'm don't know why this doesn't just bind help-form (and current-prefix-arg) esp since there is already an unbind_to which would help us do this. Since I don't know why the `bindings' are done this way, I'm leaving the unwind-protect hair, and adding GCPRO hair. * minibuf.c (read_minibuf, read_minibuf_unwind) preserve the value of current-prefix-arg. * minibuf.c: Eliminate read_minibuf_string. Move defalias for read-input to subr.el * callint.c, fns.c, lisp.h Call read_minibuf instead of read_minibuf_string. Thu Sep 4 14:02:50 1986 Richard Mlynarik (mly at prep) * fns.c (Fy_or_n_p, Fyes_or_n_p) Beep if the user types an invalid response. Wed Sep 3 02:40:40 1986 Richard M. Stallman (rms at prep) * dispnew.c (update_screen): Take out previous change. * xdisp.c (DoDsp): Move call to request_sigio after update: so it cannot be bypassed. * sysdep.c (init_sigio): set old_fcntl_flags here only once; don't change it in request_sigio. * sysdep.c ({un,}request_sigio): Set interrupts_deferred while SIGIO is unrequested. Abort if FASYNC is already set when request_sigio is called. * keyboard.c (get_input_pending): Always do FIONREAD if interrupts_deferred. Mon Sep 1 11:03:49 1986 Richard M. Stallman (rms at prep) * xterm.c/xfns.c: Many changes from rlk, including using sigblock/sigsetmask to block signals instead of turning handler off and on. * dispnew.c (update_screen): If interrupt input, wait while output gets written before returning. If observed loss of output really is a kernel bug, this may make it stop. Sun Aug 31 04:14:58 1986 Richard M. Stallman (rms at prep) * keymap.c (where_is_in_buffer): Use Fequal rather than EQ to test for a match if the object being searched for is a cons cell. Sat Aug 30 05:19:38 1986 Richard M. Stallman (rms at prep) * data.c (Fsetq_default): new function. Thu Aug 28 03:58:51 1986 Richard M. Stallman (rms at prep) * xdisp.c (display_mode_element): Cons cell whose car is a symbol now means (SYMBOL IF_TRUE_DISPLAY IF_FALSE_DISPLAY) and is equivalent to IF_TRUE_DISPLAY if SYMBOL's value is non-nil or to IF_FALSE_DISPLAY if SYMBOL is unbound or has value nil. * buffer.c (syms_of_buffer): update documentation for that. Mon Aug 25 01:27:31 1986 Richard M. Stallman (rms at prep) * fns.c (merge): Swap the arguments to the sort predicate so as to use it to compute <= rather than <. Sort had been anti-stable; now it is stable. * editfns.c (Fuser_uid, Fuser_real_uid): New functions that return values of geteuid and getuid system calls. * dired.c (Ffile_attributes): Value has additional element t iff file gid would change if Emacs deletes it and recreates it. * xdisp.c (display_mode_element): If element is a list and its car is a list, process all list elements recursively and concatenate them. Makes alists work. * xdisp.c (display_mode_string): New element type %n prints ` Narrow' and ` Def' if appropriate. * buffer.c (syms_of_buffer): Fix documentation of mode-line-format. * undo.c (Fundo_more): Fix bugs in checking len and pos for being in bounds. * eval.c (Fuser_variable_p): If documentation property is a number, negative means it's a user variable. * doc.c (Fdocumentation_property): Use abs value of property as the file position. * doc.c (FSnarf_documentation): For variables, store negative property if string starts with `*'. * editfns.c (Finsert_buffer_substring): Implement inserting part of a buffer into itself. Sun Aug 24 04:03:26 1986 Richard M. Stallman (rms at prep) * xterm.c, xfns.c, sink.h: Installed latest changes from Athena, and fixed up formatting conventions. Sat Aug 23 17:02:41 1986 Richard M. Stallman (rms at prep) * eval.c (unbind_catch): Restore gcprolist from the catchtag. Thu Aug 21 22:43:45 1986 Richard M. Stallman (rms at prep) * fileio.c (barf_or_query_if_file_exists): New second arg non-0 says query; do not call Finteractive_p. * fileio.c (Frename_file, Fcopy_to_file, Fadd_name_to_file, Fmake_symbolic_link): Interactive spec now says `p' for the third arg. If third arg is number, do call barf_or_query_if_file_exists but pass nonzero second arg in that case. * eval.c (Finteractive_p): Skip the innermost frame when examining the stack. This makes the right thing happen if called from Fbyte_code. Thu Aug 21 10:47:36 1986 Richard Mlynarik (mly at prep) * process.c (handle_process_output): do a set-buffer back to original buffer after calling a process' filter function so that all filter functions needn't save-excursion. * keymap.c (where_is_in_buffer): Don't blow out if buffer has no local map. Thu Aug 21 01:16:05 1986 Richard M. Stallman (rms at prep) * emacs.c (main): Eliminate references to environ.c. * callproc.c (Fcall_process): Pass child_setup the standard Unix environment. * process.c (create_process): likewise. * bytecode.c (Fbyte_code): At end, abort if specpdl is not back to same level it had on entry. * eval.c (unbind_catch): New way to unbind for throw. Pops catches, handlers and bindings, in one synchronized pass. Thus, when an unwind-protect is executed, all catches and handlers outside of it are still in effect. Also restore various static variables from the catchtag being unbound. struct catchtag has two new fields, gcpro and pdlcount. * eval.c (Fthrow, Fsignal): Use unbind_catch before longjmp. * eval.c (internal_catch): No need to restore anything from the catchtag after throw, because unbind_catch does it all. Must set up pdlcount and gcpro fields. * eval.c (internal_condition_case, Fcondition_case): Changed like internal_catch. * eval.c (Fcatch): use internal_catch to do the work. * eval.c (Fsignal): If no handler applies, try calling the Lisp debugger; if that fails, throw to top-level. Don't call `debugger'. * keyboard.c (debugger): Delete this function. Wed Aug 20 12:49:38 1986 Richard M. Stallman (rms at prep) * Gap motion can now quit! * insdel.c (move_gap): new name for GapTo. Callers changed. * insdel.c (InsCStr): * fileio.c (Finsert_file_contents): Call move_gap before calling record_insert. * insdel.c (del_range): Don't adjust point until after all possible errors detected, which means after gap is moved. * insdel.c (gap_right, gap_left): Check every 32000 chars for pending quit. Also speed up char-copy inner loop. * lisp.h (QUITP): New macro, nonzero if ought to quit now if poss. Wed Aug 20 00:12:25 1986 Richard M. Stallman (rms at prep) * undo.c (Fundo_more): Fix bug that was setting point to `len' field, not `pos' field. Share the error-checking code between all three types of undo record that actually make changes. * xdisp.c (display_mode_element): Fix a couple of silly bugs. * lread.c: New variable-defining functions defvar_int, defvar_lisp, defvar_bool and defvar_per_buffer are called by the new DEFVAR... macros. They ignore the doc-string argument. * lisp.h: Define macros DEFVAR_LISP, DEFVAR_INT, DEFVAR_BOOL and DEFVAR_PER_BUFFER. They expand into calls to defvar_lisp, etc. * all .c files: All Def...Var renamed to DEFVAR... in syms_of_.... * doc.c (FSnarf_documentation): Understand new DOC format where doc for function foo is named Ffoo and doc for variable foo is named Vfoo. When doc for a variable is found, store the file-position in DOC on the variable-documentation property. * doc.c (Fdocumentation_property): New Lisp function, like `get' except that if the value is a positive integer it is taken as a position in the DOC file and a string is read from that file. * filelock.c: correct spelling "supercession" -> "supersession". * undo.c: Rename RecordInsert as record_insert, and likewise RecordDelete, RecordChange and RecordChange1. * casefiddle.c, editfns.c, fileio.c, insdel.c: change callers. Tue Aug 19 03:00:43 1986 Richard M. Stallman (rms at prep) * xdisp.c (display_mode_element): Change the interpretation of symbols and lists in elements: if a symbol's value is a string, output that string literally; a list is a concatenation of all elements if the car is a string or a conditional of the cdr if the car is a symbol. * undo.c (Record...): Remember buffer->modtime as the "length" of the Uunmod. If point is at the end of a range deleted or changed, record that as the "position" of the range and make the length negative. * undo.c (Fundo_more): Undoing Uunmod does not mark as unmodified unless its remembered modtime matches the buffer's current modtime. Also handle case where length is negative in Uinsert, Uchange. Mon Aug 18 09:02:36 1986 Richard Mlynarik (mly at prep) * xdisp.c (display_mode_line): XSTRING->data, not XSTRING Fix another typo. Sun Aug 17 22:06:41 1986 Richard M. Stallman (rms at prep) * buffer.c (syms_of_buffer): Change doc for mode-line-format. * xdisp.c (display_mode_line, display_mode_element): Allow buf->mode_line_format to contain lists and symbols allowing computation and concatenation to produce the mode line. (Note that evaluation is not allowed; it would be unsafe.) display_mode_element is the recursion point for this. Sun Aug 17 19:40:05 1986 Richard Mlynarik (mly at prep) * emacs.c (main) Move init_environ up. * window.c (Fwindow_point) typo. * environ.c New function getenv replaces un*x getenv Sun Aug 17 19:04:41 1986 Richard M. Stallman (rms at prep) * window.c (Fwindow_point): When WINDOW is the selected window and its buffer is selected too, return current value of point. The pointm field of the window is not meaningful in such cases. * unexec.c (write_segment): If hit nonexistent page, must write zeros, not return. Sun Aug 17 14:28:48 1986 Richard Mlynarik (mly at prep) * callproc.c, process.c (Fcall_process, create_process) Use `alloca' versions of environment-hacking functions (ie current_environ_size and get_current_environ rather than current_environ and free_environ) * emacs.c (main): Call syms_of_environ, init_environ. * config.h., config.h.dist Increase PURESIZE again (sigh) * unexec.c (write_segment): Kludgey coercions ("(int)") to get this line to compile: nwrite = (((int) ptr + 128) & ~127) - (int) ptr; Also changed incorrect ~128 to ~127. * process.c: New function Fprocess_list. Sun Aug 17 05:56:29 1986 Richard M. Stallman (rms at prep) * crt0.c, alloca.s: Remove hack_sky (special for sun2) and the call to it. No longer needed since floating point is no longer used. * unexec.c: New compiler flag A_TEXT_OFFSET is defined for machines in which the a.out file header counts as the first few bytes of the text segment. The definition of A_TEXT_OFFSET would normally be sizeof (HDR). It has other terms added in on some machines (sequent). Sat Aug 16 18:42:35 1986 Richard Mlynarik (mly at prep) * eval.c (Fmacroexpand) Use car of nthcdr, not nth. * fns.c Define Fcopy_alist (used to be in subr.el) Move Fnth to subr.el * ymakefile Include environ.c * callproc.c, process.c (child_setup, Fcall_process, create_process): Take/pass environment arg. * environ.c: New file * sysdep.c: Move VMS sys_getenv to environ.c * editfns.c: Move getenv to environ.c Sat Aug 16 17:25:41 1986 Richard M. Stallman (rms at prep) * xdisp.c (display_text_line): * indent.c (current_column, ToCol, position_indentation): * indent.c (Fmove_to_column, compute_motion): Bring tab_width in range if it is very large. Fri Aug 15 03:05:00 1986 Richard M. Stallman (rms at prep) * fileio.c (Fwrite_region): Do the fsync before the fstat; that may prevent what appear to be spurious "file has changed on disk" warnings. Update bf_cur->modtime before signaling "IO error writing" to avoid more such warnings. * Make ctl-arrow, case-fold-search, etc. behave exactly as if they had been made local with make-variable-buffer-local. The default values live in struct buffer buffer_defaults. They also live in buffers that do not have local values. Each buffer has a local_var_flags slot with a bit for each variable, saying which variables are local in that buffer. * buffer.h: New buffer slot local_var_flags. * buffer.c: New structures buffer_defaults and buffer_local_flags. (init_buffers_once): store default values for local slots into buffer_defaults. (reset_buffer_variables): Copy default values from buffer_defaults into the buffer being reset. (syms_of_buffer): Variables default-ctl-arrow, etc., now forward to slots in buffer_defaults. * data.c (Fset, Fset_default, Fdefault_value, Fkill_local_variable): Know that a Lisp_Buffer_Objfwd has default value if the buffer_local_flags slot is nonzero, and a buffer uses that default unless its local_var_flags contains the bit of the buffer_local_flags for the slot. * alloc.c (Fgarbage_collect): Call mark_buffer on buffer_defaults. Thu Aug 14 18:40:13 1986 Richard M. Stallman (rms at prep) * unexec.c (copy_text_and_data): Write text and data separately if COFF (just as if not COFF). (make-hdr): if COFF and NO_REMAP, don't alter some f_ohdr fields. Thu Aug 14 16:35:21 1986 Richard Mlynarik (mly at prep) * editfns.c (getenv) Make getenv useful interactively. Move defaliases to fsets in subr.el Thu Aug 14 04:45:39 1986 Richard M. Stallman (rms at prep) * unexec.c: unexec_data_start records the ultimate corrected data_start from make_hdr; copy_text_and_data starts writing data segment from that address. Wed Aug 13 04:45:18 1986 Richard M. Stallman (rms at prep) * buffer.c (Fkill_buffer): Combine Fdelete_buffer_internal into this function. Simplify. Just return immediately if attempted to kill the minibuffer. * lisp.h: Define XSETPNTR and make XSETCONS (etc) use it. By default XSETPNTR is the same as XSETUINT. * lread.c (oblookup, map_obarray): Use XUINT, not XSYMBOL, to check for zero to detect end of bucket. On machines where all pointers have high bits set, XSYMBOL would never return zero. * alloc.c: change vars most_negative_fixnum and dont_copy_flag to constant macros ARRAY_MARK_FLAG and DONT_COPY_FLAG, defined normally based on INTBITS but overridable by m-*.h. * process.c (handle_process_output): Write in buffer even if buffer is read-only. * fileio.c (barf_or_query_if_file_exists): Rearrange: don't use comma around calls to NULL, so can compile using union type. Tue Aug 12 10:45:44 1986 Richard Mlynarik (mly at prep) * buffer.c (SetBfp, syms_of_buffer) Dike out debug-check-symbol code. I believe that this bug has evaporated. * fileio.c (barf_or_query_if_file_exists) ! => !NULL. Also use local variable for Lisp_object for bd compilers. Mon Aug 11 12:22:05 1986 Richard Mlynarik (mly at prep) * buffer.c (Fbarf_if_buffer_read_only) Include buffer in call to Fsignal. * print.c (Fwrite_char) Really default stream to standard-output. Sun Aug 10 00:18:48 1986 Richard Mlynarik (mly at prep) * eval.c (and abbrev.c, buffer.c, callint.c, cmds.c, keyboard.c, lread.c, lisp.h) Allow Fapply to take an &rest arg, the last of which is spread. (So (apply '+ 1 '(2 3)) => 6) Make Ffuncall do the work for Fapply, rather than duplicating all that code. Define apply1 for c code which needs it. Define call0 for c code which thought it needed Fapply. Fri Aug 8 11:56:10 1986 Richard Mlynarik (mly at prep) * ymakefile Don't assemble alloca.s if HAVE_ALLOCA. Even though the whole of this file is contained in a `#ifndef HAVE_ALLOCA ... #endif' a disgusting bug in cc (at least here, vax 4.2bsd) meant that this file was being assembled even though cc was passed the -E flag! Gag me with a unix-pinhead. * m-vax.h Define HAVE_ALLOCA if BSD * unexec.c (write_segment) Rename variable `fd' to `new' for macro PERROR. Wed Jul 30 21:23:27 1986 Richard M. Stallman (rms at prep) * fileio.c (Fwrite_region): add call to fsync before close. * xdisp.c (redisplay_window): Don't look at ->start in windows that have subwindows, since it is nil there. * window.c (save_window_restore): Avoid doing Fset_buffer on a dead buffer. Use the selected window's new current buffer in that case. Mon Jul 28 21:01:35 1986 Richard M. Stallman (rms at prep) * fileio.c (Finsert_file_contents): Don't mark buffer modified if inserted a null file. * fileio.c (Fcopy_file, e_write): Use 16k buffer size. Thu Jul 17 05:05:50 1986 Richard M. Stallman (rms at prep) * unexec.c (copy_sym): Put in missing #endif. * alloc.c (Fpurecopy, mark_object): Flush VIRT_ADDR_VARIES conditional; always use range from pure to pure + PURESIZE. Use type PNTR_COMPARISON_TYPE as the type to compare in. This is normally unsigned int but m- file may override this. * lisp.h (CHECK_IMPURE): Use PNTR_COMPARISON_TYPE, and always use the range from pure to pure + PURESIZE unless PNTR_COMPARISON_TYPE is defaulted. * eval.c (unbind_to): New temporary var `tmp' to avoid a Gould compiler bug. * term.c (calculate_ins_del_char_costs): * window.c (change_window_height): Changed floating point arithmetic to fixed point. * sysdep.c: Replace ad-hoc conditionals with new flags HAVE_VFORK, HAVE_DUP2 and HAVE_GETTIMEOFDAY. Change s-hpux.h and m-stride.h. * sysdep.c (init_sys_modes for VMS): Set TT2$M_XON. * process.c (create_process): On USG systems that have TIOCNOTTY, do the setpgrp here before reopening the pty rather than waiting for child_setup. * window.c (make_window): size given to make_vector was one too small. Thu Jul 10 12:19:07 1986 Richard M. Stallman (rms at prep) * keymap.c (Fdescribe_bindings): change XSETTYPE/XSETBUFFER to XSET. (describe_command): change XSETSTRING to XSET. * window.c (Fmove_to_window_line): delete unused start =. * xdisp.c (DoDsp) delete unused all_windows initializer. * dispnew.c (update_line): delete unused osp =. * minibuf.c (do_completion): delete unused completedp initializer. * search.c (Freplace_match): delete unused some_multiletter_word init. * alloc.c (gc_sweep): delete unused next initializers. * fns.c (concat): after error on non-int elt for string, do store the new value from the error handler. * lread.c (read1): comment out unused end =. * lread.c (read_list): delete unused tail =. * data.c (Fmake_variable_buffer_local): if value type is Lisp_Some_Buffer_Local_Value, change it to Lisp_Buffer_Local_Value permanently. * undo.c (record_block): delete unused cp =. Don't bother reallocing if n = 0 after first batch. * fileio.c (Fverify_visited_file_modtime): If CHECK_BUFFER changes buf, use the changed value. Mon Jul 7 13:59:16 1986 Richard M. Stallman (rms at prep) * alloc.c (mark_buffer): mark the selective_display_ellipses slot. Wed Jun 25 08:39:56 1986 Richard M. Stallman (rms at prep) * window.c (Frecenter): Fix bug in last change: change applied to M-- arg ratherthan C-u by mistake. Thu Jun 19 12:32:53 1986 Richard M. Stallman (rms at prep) * ymakefile (CPP): Now defined by default as `cc -E'. * Makefile: likewise. * More 3b changes: * ymakefile: Allow config to specify LIBS_TERMCAP even if TERMINFO. * sysdep.c: Delete the sign-extension functions; just define a variable sign_extend_temp. * m-3b.h renamed to m-3b20.h. Now defines ATT3B20 as well as ATT3B. New definitions for XINT and SIGN_EXTEND_CHAR. * sysdep.c (readdirver): New VMS-only function: like readdir but return each version as separate filename. * dired.c (file_name_completions): New arg ver_flag. All callers changed. * dired.c (Ffile_name_all_versions): New function, VMS only. * unexec.c (copy_sym): Remove spurious #else on sun3 conditional. The old #else code is now unconditional. * window.c (Fdisplay_window): Split largest window only if full screen width. The conditional was backwards. Tue Jun 17 05:49:16 1986 Richard M. Stallman (rms at prep) * process.c (Fsend_region): Previous change forgot to assign anything to start1. Fri Jun 13 02:09:29 1986 Richard M. Stallman (rms at prep) * emacs.c (Fdump_emacs): Use start_of_text, not &_start, as entry address for unexec. * alloc.c: Use XPNTR, not XUINT, when checking for pureness. * data.c: When indirecting through Lisp_Buffer_Objfwd, use XUINT to get the offset, not XOBJFWD. * lisp.h: New macro XPNTR is used as subroutine by all of XCONS, XSTRING, etc. Define it like XUINT normally. If DATA_SEG_BITS is defined, XPNTR or's that into the result. Use XPNTR in CHECK_IMPURE. * sysdep.c (end_of_{text,data}): Do compile these. rt-pc unexec needs them. * sysdep.c (start_of_bss): New function. * unexec.c (copy_text_and_data, write_segment): Write text and data segments separately. Use new subroutine write_segment to do each one. * process.c (Fprocess_exit_status): New name for Fprocess_reason. Wed Jun 11 17:01:32 1986 Richard M. Stallman (rms at prep) * abbrev.c (Fexpand_abbrev): Delete the - inserted by abbrev-prefix-mark, if any. * filelock.c (lock_file): Check for modifying a buffer whose file has changed and call ask-user-about-supercession-threat, which can ask for confirmation and get an error. Tue Jun 10 00:45:11 1986 Richard M. Stallman (rms at prep) * crt0.c: Merge changes for Nu. * unexec.c (make_hdr): Fix handling of blockcopy_start; for the sake of Nu machine. * fileio.c (Fcopy_file): optional 4th arg non-nil means preserve the last-modified time. * Make C-M-v in minibuffer scroll the minibuffer's help window if any. * window.c (save_window_{save,restore}): Save and restore minibuf_scroll_window. * window.c (Fscroll_other_window): If minibuffer is selected, scroll minibuf_scroll_window. * minibuf.c (read_minibuf): set minibuf_scroll_window to nil. * window.c (Frecenter): With just C-u as arg, recenter point but don't erase the screen. Mon Jun 9 09:27:09 1986 Richard M. Stallman (rms at prep) * process.c (Fsend_region): * fileio.c (Fwrite_region): * editfns.c (Fchar_after, save_restriction_restore): Avoid using XINT in args to other macros. * sysdep.c: New function char_sign_xtnd for ATT3B. * lisp.h: Don't redefine XINT if it's already defined. So m-3b.h can override it. * ymakefile: If NO_REMAP, use the standard crt0.o but precede it with pre_crt0.o whose job is to define data_start. * buffer.h. buffer.c: New per-buffer variable selective-display-ellipses. * xdisp.c (display_text_line), indent.c (compute_motion): Let bf_cur->selective_display_ellipses control display of ... before invisible lines. * lread.c (openp, Fload): openp now takes a sequence of suffixes with colons between. It loops over suffixes faster than over directories. load takes new fourth arg NOSUFFIXES. Sun Jun 8 16:01:48 1986 Richard M. Stallman (rms at prep) * paths.h: Remove . from load-path. * lread.c: Make "load" no longer interactive. * keyboard.c: Introduce BUFFER_SIZE_FACTOR to make some keyboard buffers 16 times as big when X windows exist. Sat Jun 7 17:08:19 1986 Richard M. Stallman (rms at prep) * eval.c (call_debugger): Don't do a debug-on-call for calling the debugger. * keyboard.c (gobble_input): Must really use FIONREAD. * keyboard.c (command_loop{,_1,_2}, top_level_{1,2}): Now Frecursive_edit calls command_loop, which does the catches and calls command_loop_2, which does the error handling, which calls command_loop to do the real work. Also, top_level_1 does a condition-case around top_level_2, which does the work. Previously, the error handling was outside the catch for top-level. Then if handling an error ran an unwind protect form, the catch was not in effect; so ^G, or the debugger Q command, would not work inside of them. Fri Jun 6 00:28:18 1986 Richard M. Stallman (rms at prep) * keymap.c (get_keymap{,_1}): Create get_keymap_1 that takes arg saying whether to get error. get_keymap calls that, saying do get an error. * keyboard.c (get_char): If rereading a char, do put it in the echo buffer if the echo buffer is empty. Fixes problem that C-s C-h would never echo the C-h. * window.h: New window slot start_at_line_beg, holds t if window's start was the beginning of a line. * window.c: update this wherever ->start is updated. (But not always correctly). * xdisp.c (redisplay_window): update start_at_line_beg, and also find a new start if the old start used to be a line beginning but no longer is (which implies text changes just before it). * keyboard.c (get_input_pending): Don't bother with FIONREAD if interrupt_input; just use kbd_count. * fns.c: Assume KERNEL_FILE, LDAV_SYMBOL and NLIST_STRUCT are fully set up by the s- and m- files. * emacs.c (main): Don't call `signal' if in batch mode and not initialized and dumping is possible. * keyboard.c (init_keyboard): likewise for SIGIO. * unexec.c (make_hdr): Copy entire header of old file as base for header of new file. Eliminates most machine-specific conditionals. * terminfo.c: make tparam work by calling tparm. * term.c, cm.h: Eliminate `Tab' macro. * s-usg5.2.h, s-usg5.2.2.h: set the TERMINFO flag. * fileio.c (Ffile_newer_than_file_p): New Lisp primitive. * fileio.c (Ffile_exists_p): this is now distinct from Ffile_readable_p; it checks only for existence, not for readability. * editfns.c (Fgoto_char): Use new interactive code N. * callint.c (Fcall_interactively): New code N means use prefix argif have one, else read number from minibuffer. * buffer.c (record_buffer): Don't use Frassq, Fmemq or Fdelq since their loops allow quitting. Write a spacial loop by hand. Thu Jun 5 00:13:27 1986 Richard M. Stallman (rms at prep) * process.c: Add MASSCOMP conditionals for pty and tty names. New way to check pty accessibility with `access'. * unexec.c (make_hdr): MASSCOMP has its own special field. * sysdep.c: Use HAVE_TERMIO conditionals instead of USG conditionals in many places. Use INTERRUPTABLE_OPEN and INTERRUPTABLE_IO conditionals to decide whether to include the functions sys_read, sys_write, sys_open. child_setup_tty must do FIOASYNC on masscomp. * fns.c (concat): Add MASSCOMP_REGISTER_BUG conditional. * editfns.c (init_editfns): Always check LOGNAME if no USER var. * dispnew.c: Now depends on HAVE_TERMIO. * crt0.c: BOGUS flag renamed CRT0_DUMMIES. Also now this is never assumes; each m- file must set it to use that code. * crt0.c: Two new flags: GLOBAL_START_DOT and GLOBAL_START_NO_DOT, control .globl start, etc. m- files must define these as needed. To have no effect, must define one or the other whenever CRT0_DUMMIES is set except for masscomp. GLOBAL_START_NO_DOT for tower32, GLOBAL_START_DOT for all others. * term.c, termchar.h: Define new flag var no_redraw_on_reenter; nonzero means no need to set screen_garbaged on resuming after a suspension. * sysdep.c (init_sys_modes): don't set screen_garbaged after resumption if that flag is set. * dispnew.c (syms_of_dispnew): make Lisp var no-redraw-on-reenter, * process.c (Fprocess_reason): New function. * dispnew.c (change_screen_size): New arg PRETEND. If it's zero, set ScreenRows or ScreenCols. Fset_screen_{width,height} take new arg as well to control value of PRETEND. * sysdep.c (child_setup_tty for USG): Turn ICANON on, and set VKILL and VERASE to 0377. Don't frob VMIN and VTIME (said to be unnecessary here). * keyboard.c (command_loop, Frecursive_edit): Call top_level_1 only from command_loop. Do it before command_loop_1. Put catch for top-level around it. * xdisp.c (try_window_1): use scroll_cost to decide whether scrolling, as determined from ins/del records, is better than simple reprinting. * scroll.c (scroll_cost): New function computes what cost would be to do scroll_screen_lines. * xdisp.c (display_text_string): Display minibuf_prompt only if vpos is the top of the minibuffer. Attempts to fix the bug where the prompt appears on all the lines of an empty minibuffer. Wed Jun 4 20:35:49 1986 Richard M. Stallman (rms at prep) * fileio.c (Fdefine_logical_name): For VMS: create a logical name translation. * emacs.c (main): (HAVE_X_WINDOWS) New variable alternate_display, set with a -d switch. * keyboard.c, sysdep.c: Create new system-independent function sys_suspend. All places that want to suspend now use sys_suspend. Delete fake_suspend and make its definition one of the cases for sys_suspend; but require the caller to change the terminal modes, on all system versions. * Merged in VMS conditionals in numerous files. Sun Jun 1 04:33:34 1986 Richard M. Stallman (rms at prep) * emacs.c (main, Fdump_emacs): Use new arg to malloc_init to say what function to call for warnings. * unexec.c, malloc.c, getpagesize.h: The code to define getpagesize () is now in getpagesize.h. * process.c (reate_process), callproc.c (child_setup): Move call to child_setup_tty from child_setup to create_process, so it's not done for synchronous subprocesses. * sysdep.c (child_setup_tty): omit it if not subprocesses. * alloc.c (mark_object), lread.c (DefLispVar): Protect the C variable with staticpro. Therefore no more need to mark thru a Lisp_Objfwd.
