 749         (files_command): Don't use tk_listboxSingleSelect.

 754         (listing_window_button_1, file_popup_menu): Use tk_popup.
 755         (ButtonRelease-1 binding): Just remove tag from window; rest
 756         handled by Tk.
 757
 758         * gdbtk.c (gdbtk_query): Use Tcl_Merge to provide quoting.
 759         (call_wrapper): Use Tcl_Eval, not Tcl_VarEval.
 760         (gdbtk_call_command): Ditto.
 761

 779 Sat Aug 19 17:20:22 1995  Michael Tiemann  <tiemann@axon.cygnus.com>
 780
 781         * gdbtk.tcl: ENABLE comes back as "1" or "0", not "enable" or
 782         "disable".
 783         Also, wire up the breakpoint window so that it can be demo'd.
 784
 785 Tue Aug  1 11:44:53 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
 786

 803
 804 Fri May 19 06:15:40 1995  Jim Kingdon  <kingdon@deneb.cygnus.com>
 805
 806         * gdbtk.c: Conditionalize use of stdarg rather than varargs on
 807         ANSI_PROTOTYPES not __STDC__; it must match the definition of
 808         PARAMS.
 809
 810 Thu May 18 15:58:46 1995  J.T. Conklin  <jtc@rtl.cygnus.com>

 824 Tue Apr 11 11:07:12 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
 825
 826         * gdbtk.c (gdbtk_init): If SIOCSPGRP is not available, but
 827         F_SETOWN is, use that.
 828
 829 Thu Apr  6 17:00:46 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
 830
 831         * Makefile.in (X11_INCLUDES): Define as empty.
 832         (X11_CFLAGS): Define as including $(X11_INCLUDES).
 833         (X11_LIB_SWITCHES): Define as empty.
 834         (X11_LIBS): Define as -lX11.
 835
 836         * configure.in (enable_gdbtk): If gdbtk, support the --x-includes
 837         and --x-libraries switches, setting the X11_INCLUDES and
 838         X11_LIB_SWITCHES respectively.  Instead of using a hardcoded -lX11
 839         in ENABLE_CLIBS, use the X11_LIB_SWITCHES and X11_LIBS variables.
 840
 841         * gdbtk.c (gdbtk_init): If SIOCSPGRP is not available, don't use
 842         it.  This means that the stop button doesn't work, but is better
 843         than nothing.
 844
 845 Wed Mar 29 17:09:29 1995  Stu Grossman  (grossman@cygnus.com)
 846
 847         * Makefile.in (gdbtk.o):  Use X11_CFLAGS to provide alternate
 848         locations (per-host) for X11 include files.
 849         * config/pa/hppahpux.mh (XM_CLIBS):  Add -L/usr/lib/X11R5 to force
 850         the use of R5 libs.
 851         (X11_CFLAGS):  Add this to indicate the locs
 852         of the R5 include files.
 853
 854 Wed Mar  8 16:12:21 1995  Stu Grossman  (grossman@cygnus.com)
 855
 856         * gdbtk.c (gdb_get_breakpoint_info):  Return error if breakpoint
 857         type is not bp_breakpoint.
 858
 859 Tue Feb 14 17:16:41 1995  Stu Grossman  (grossman@cygnus.com)
 860
 861         * gdbtk.c: Ditto.
 862         * gdbtk.c: General cleanups, get rid of unused variables.  Redo
 863         handling of stdout/stderr to just return output as the result of
 864         the tcl command that caused the output.  Cleanup -Wall stuff.
 865         * (breakpoint_notify):  Now returns just action and breakpoint
 866         number.
 867         * (gdb_get_breakpoint_list):  New routine.  Does the obvious.
 868         * (gdb_get_breakpoint_info):  Mostly derived from the old
 869         breakpoint_notify, but returns lots more info.
 870         * (dsprintf_append_element):  Helper routine, works like printf,
 871         but appends a tcl element onto the specified DString.  Good for
 872         building up lists as return values.
 873         * (gdbtk_enable/disable_breakpoint):  Go away.  Replaced with
 874         gdbtk_modify_breakpoint.
 875         * (*many routines*):  Use new result protocol.
 876         * (call_wrapper):  Make sure that recursive calls don't trash results.
 877         * gdbtk.tcl:  New windows, autocmd, and breakpoints.
 878         * (gdbtk_tcl_fputs):  Don't use $current_output_win redirection
 879         anymore.  It's not needed (in fact, this routine may not be needed
 880         anymore).
 881         * (gdbtk_tcl_breakpoint):  Change to reflect new breakpoint
 882         notification protocol.
 883         * (gdbtk_tcl_busy gdbtk_tcl_idle):  Straighten out buttons, remove
 884         catches.
 885         * (interactive_cmd):  Use this wrapper around button invocations
 886         of many commands.  This will catch errors and put the results into
 887         the command window.  It also updates all the other windows.
 888         * Also, change reliefs of most things to sunken.  This actually
 889         looks better.
 890         * (create_file_win):  Fix margin binding to allow breakpoints to
 891         work again.
 892         * (create_asm_win):  Use return value of gdb_disassemble instead
 893         of implicit I/O to the command window.
 894         * (create_command_window):  Use new result protocol to get output
 895         from commands.
 896
 897 Sun Feb  5 20:32:44 1995  Jim Kingdon  (kingdon@lioth.cygnus.com)
 898
 899         * gdbtk.c (gdb_disassemble): Deference pointer to function before
 900         calling it (pre-ANSI compilers generally require this).
 901
 902 Fri Feb  3 11:19:20 1995  Stu Grossman  (grossman@cygnus.com)
 903
 904         * gdbtk.c (gdb_disassemble): Get rid of
 905         dis_asm_read_memory_hook.  We can now call the disassemblers
 906         directly and have no need for this hook anymore.
 907
 908 Mon Jan 30 17:34:24 1995  Stu Grossman  (grossman@cygnus.com)
 909
 910         * gdbtk.tcl (create_file_win):  Disable old popup menu for source
 911         window.
 912
 913 Wed Jan 25 18:23:46 1995  Stu Grossman  (grossman@cygnus.com)
 914
 915         * gdbtk.c (gdbtk_init):  Prevent segfault when gdbtk.tcl can't be
 916         found.
 917         * gdbtk.tcl:  Initialize expr_update_list() to prevent errors when
 918         popping up expression window for the first time.
 919
 920 Tue Jan 24 12:10:28 1995  Stu Grossman  (grossman@cygnus.com)
 921
 922         * gdbtk.tcl (create_registers_window):  Work around a radiobutton
 923         widget bug to make Options|Natural button work.
 924
 925         * gdbtk.c (gdb_disassemble):  Fix problem with source+assembly and
 926         g++ caused by out-of-order pc's.
 927         * gdbtk.tcl (files_command):  Remove duplicate file names.  Also,
 928         add scrollbar.
 929
 930 Mon Jan 23 17:21:09 1995  Stu Grossman  (grossman@cygnus.com)
 931
 932         * gdbtk.tcl:  Take .gdbtkinit if it exists.  Makes gdbtk match the
 933         doc!
 934
 935 Thu Jan 12 15:02:40 1995  Stu Grossman  (grossman@cygnus.com)
 936
 937         * gdbtk.c, gdbtk.tcl:  Update/add copyright.
 938         * gdbtk.tcl (build_framework):  Several fixes for filespec widget,
 939         including dismiss button, and better error handling.

 941
 942 Wed Jan 11 17:06:55 1995  Stu Grossman  (grossman@cygnus.com)
 943
 944         * gdbtk.tcl:  Add button to control mixed source disassembly.
 945         Use text widgets in expr window.  The give me more control over
 946         layout.
 947         Add auto-updating of exprs in expression window.
 948         Handle expressions out of scope a bit better.
 949         Make selected window pop up to the top when invoked via the
 950         menubar.
 951         Make copyright message have raised relief.
 952
 953         * gdbtk.c (gdbtk_init):  Improve handling for errors in gdbtk.tcl
 954         during startup.
 955
 956 Thu Jan  5 17:38:29 1995  Stu Grossman  (grossman@cygnus.com)
 957
 958         * gdbtk.c (finish_saving_output):  Don't do anything if not saving
 959         output.
 960         * (breakpoint_notify):  Don't send null filename to tcl.
 961         * (gdb_eval):  New tcl command to eval an expression.
 962         * (gdb_disassemble):  New tcl command to do disassembly.  This
 963         allows tcl code to choose between exec file and target memeory,
 964         and can also do mixed source and assembly.
 965         * (gdbtk_init):  Move reading of gdbtk.tcl to the end to make sure
 966         that more of the environment is set up.  Also, create link between
 967         gdb and tcl vars disassemble{-_}from{-_}exec.
 968
 969         * gdbtk.tcl:  New expression window support.
 970         * Make assembly window be 80 columns wide.

 972         disassembly from exec file or target.
 973         * Change View menubar item to Options.
 974
 975         * Get rid of Stack, Breakpoints, Signals, and Variables Windows,
 976         since they don't exist yet.
 977
 978         * Pop up a copyright window on startup.
 979
 980 Wed Jan  4 19:49:10 1995  Stan Shebs  <shebs@andros.cygnus.com>
 981
 982         * gdbtk.tcl (build_framework): Add standard commands menu, more
 983         windows to standard windows menu.
 984         (not_implemented_yet): Clarify message.
 985
 986 Fri Dec 30 15:49:00 1994  Stan Shebs  <shebs@andros.cygnus.com>
 987
 988         * gdbtk.tcl (FSBox): New proc, File Selection Box code from exmh.
 989         (not_implemented_yet): New proc.
 990         (build_framework): Add various file commands to file menu.
 991
 992 Fri Dec 23 16:18:50 1994  Stu Grossman  (grossman@cygnus.com)
 993
 994         * gdbtk.c (gdbtk_wait gdbtk_init):  Portability improvements for
 995         SIGIO handling.
 996

 998
 999         * gdbtk.tcl (update_assembly):  Force update to make sure that pc
1000         is visible when creating new assembly windows.
1001
1002 Sun Dec 18 23:31:20 1994  Stu Grossman  (grossman@cygnus.com)
1003
1004         * gdbtk.c (gdbtk_wait gdbtk_init):  Use different method of
1005         enabling I/O interrupts for SVR4 (streams).
1006         * (start_saving_output save_output get_saved_output
1007         finish_saving_output flush_holdbuf gdbtk_flush gdbtk_fputs
1008         gdbtk_init):
1009         Totally revamp to use TCLs dynamic string functions.  Also, quote
1010         all data passed back to TCL to prevent errors with unmatched
1011         braces, odd characters, etc...  This fixes several wierd problems
1012         with outputting strings containing unmatched braces.
1013         * (breakpoint_notify gdb_loc):  Use long hex format to output
1014         addresses of breakpoints and PCs.  This fixes some Alpha problems.
1015         * (breakpoint_notify):  Add stream arg to call to gdbtk_fputs.
1016         * (gdb_listfiles):  Also, go through the symtabs when looking for
1017         files.  This makes xcoff work (sort of), but probably breaks
1018         something else.
1019         * (gdb_stop):  Return TCL_OK instead of nothing.  This fixes odd
1020         TCL errors when hitting stop button.
1021         * (tk_command):  Don't pass interp->result on to Tcl_{Var}Eval, as
1022         that will trash the result.  strdup the result instead and pass
1023         that on.  Improve error handling as well.
1024
1025         * gdbtk.tcl (gdbtk_tcl_flush):  Use global def of
1026         current_output_win.  Makes flushing actually work!
1027         * (asm_win_name create_asm_win update_assembly):  Bunch of fixes
1028         to make assembly windows stop flashing when loading a new file.
1029         * (gdbtk_tcl_busy gdbtk_tcl_idle):  Use catch to prevent gdb_cmd
1030         errors from losing control.
1031         * (create_source_window):  Add source file selection to View menu.
1032         * (create_command_window (<Key-Return> binding):  Quote text fed
1033         into gdb_cmd to prevent eval errors.

1036
1037         * gdbtk.c: Improve mechanism for capturing output values.
1038         (full_filename): Remove.
1039         (gdb_cmd call_wrapper gdbtk_init): Protect all calls from tcl land
1040         with call_wrapper.  This prevents longjmps (usually via error())
1041         from jumping out of tcl/tk and leaving things in an indeterminate
1042         state.
1043         (gdbtk_fputs): Differentiate stdout from stderr when passing text
1044         into tcl land.
1045         * gdbtk.tcl: New view option to disable line numbers.  Put catch
1046         around most uses of gdb_cmd.  Add update button to reg config
1047         window.  Stop doing immediate updates when selecting registers.
1048         Change register view values into checkbuttons.
