1050
1051         * gdbtk.c (gdb_get_breakpoint_info):  Return error if breakpoint
1052         type is not bp_breakpoint.
1053
1054 Tue Feb 14 17:16:41 1995  Stu Grossman  (grossman@cygnus.com)
1055
1056         * gdbtk.c: Ditto.
1057         * gdbtk.c: General cleanups, get rid of unused variables.  Redo
1058         handling of stdout/stderr to just return output as the result of
1059         the tcl command that caused the output.  Cleanup -Wall stuff.
1060         * (breakpoint_notify):  Now returns just action and breakpoint
1061         number.
1062         * (gdb_get_breakpoint_list):  New routine.  Does the obvious.
1063         * (gdb_get_breakpoint_info):  Mostly derived from the old
1064         breakpoint_notify, but returns lots more info.
1065         * (dsprintf_append_element):  Helper routine, works like printf,
1066         but appends a tcl element onto the specified DString.  Good for
1067         building up lists as return values.
1068         * (gdbtk_enable/disable_breakpoint):  Go away.  Replaced with
1069         gdbtk_modify_breakpoint.
1070         * (*many routines*):  Use new result protocol.
1071         * (call_wrapper):  Make sure that recursive calls don't trash results.
1072         * gdbtk.tcl:  New windows, autocmd, and breakpoints.
1073         * (gdbtk_tcl_fputs):  Don't use $current_output_win redirection
1074         anymore.  It's not needed (in fact, this routine may not be needed
1075         anymore).
1076         * (gdbtk_tcl_breakpoint):  Change to reflect new breakpoint
1077         notification protocol.
1078         * (gdbtk_tcl_busy gdbtk_tcl_idle):  Straighten out buttons, remove
1079         catches.
1080         * (interactive_cmd):  Use this wrapper around button invocations
1081         of many commands.  This will catch errors and put the results into
1082         the command window.  It also updates all the other windows.
1083         * Also, change reliefs of most things to sunken.  This actually
1084         looks better.
1085         * (create_file_win):  Fix margin binding to allow breakpoints to
1086         work again.
1087         * (create_asm_win):  Use return value of gdb_disassemble instead
1088         of implicit I/O to the command window.
1089         * (create_command_window):  Use new result protocol to get output
1090         from commands.

1092 Sun Feb  5 20:32:44 1995  Jim Kingdon  (kingdon@lioth.cygnus.com)
1093
1094         * gdbtk.c (gdb_disassemble): Deference pointer to function before
1095         calling it (pre-ANSI compilers generally require this).
1096
1097 Fri Feb  3 11:19:20 1995  Stu Grossman  (grossman@cygnus.com)
1098
1099         * gdbtk.c (gdb_disassemble): Get rid of
1100         dis_asm_read_memory_hook.  We can now call the disassemblers
1101         directly and have no need for this hook anymore.
1102
1103 Mon Jan 30 17:34:24 1995  Stu Grossman  (grossman@cygnus.com)
1104
1105         * gdbtk.tcl (create_file_win):  Disable old popup menu for source

1109
1110         * gdbtk.c (gdbtk_init):  Prevent segfault when gdbtk.tcl can't be
1111         found.
1112         * gdbtk.tcl:  Initialize expr_update_list() to prevent errors when
1113         popping up expression window for the first time.
1114
1115 Tue Jan 24 12:10:28 1995  Stu Grossman  (grossman@cygnus.com)
1116
1117         * gdbtk.tcl (create_registers_window):  Work around a radiobutton
1118         widget bug to make Options|Natural button work.
1119
1120         * gdbtk.c (gdb_disassemble):  Fix problem with source+assembly and
1121         g++ caused by out-of-order pc's.
1122         * gdbtk.tcl (files_command):  Remove duplicate file names.  Also,
1123         add scrollbar.
1124
1125 Mon Jan 23 17:21:09 1995  Stu Grossman  (grossman@cygnus.com)
1126
1127         * gdbtk.tcl:  Take .gdbtkinit if it exists.  Makes gdbtk match the
1128         doc!
1129
1130 Thu Jan 12 15:02:40 1995  Stu Grossman  (grossman@cygnus.com)
1131
1132         * gdbtk.c, gdbtk.tcl:  Update/add copyright.
1133         * gdbtk.tcl (build_framework):  Several fixes for filespec widget,
1134         including dismiss button, and better error handling.
1135         * (create_command_win):  Bind button 2 to retrieve selection.
1136
1137 Wed Jan 11 17:06:55 1995  Stu Grossman  (grossman@cygnus.com)
1138
1139         * gdbtk.tcl:  Add button to control mixed source disassembly.
1140         Use text widgets in expr window.  The give me more control over
1141         layout.
1142         Add auto-updating of exprs in expression window.
1143         Handle expressions out of scope a bit better.
1144         Make selected window pop up to the top when invoked via the
1145         menubar.
1146         Make copyright message have raised relief.
1147
1148         * gdbtk.c (gdbtk_init):  Improve handling for errors in gdbtk.tcl
1149         during startup.
1150
1151 Thu Jan  5 17:38:29 1995  Stu Grossman  (grossman@cygnus.com)
1152
1153         * gdbtk.c (finish_saving_output):  Don't do anything if not saving
1154         output.
1155         * (breakpoint_notify):  Don't send null filename to tcl.
1156         * (gdb_eval):  New tcl command to eval an expression.
1157         * (gdb_disassemble):  New tcl command to do disassembly.  This
1158         allows tcl code to choose between exec file and target memeory,
1159         and can also do mixed source and assembly.
1160         * (gdbtk_init):  Move reading of gdbtk.tcl to the end to make sure
1161         that more of the environment is set up.  Also, create link between
1162         gdb and tcl vars disassemble{-_}from{-_}exec.
1163
1164         * gdbtk.tcl:  New expression window support.
1165         * Make assembly window be 80 columns wide.
1166         * Use new disassembly method.  Add menu items to select
1167         disassembly from exec file or target.
1168         * Change View menubar item to Options.
1169

1172
1173         * Pop up a copyright window on startup.
1174
1175 Wed Jan  4 19:49:10 1995  Stan Shebs  <shebs@andros.cygnus.com>
1176
1177         * gdbtk.tcl (build_framework): Add standard commands menu, more
1178         windows to standard windows menu.
1179         (not_implemented_yet): Clarify message.
1180
1181 Fri Dec 30 15:49:00 1994  Stan Shebs  <shebs@andros.cygnus.com>
1182
1183         * gdbtk.tcl (FSBox): New proc, File Selection Box code from exmh.
1184         (not_implemented_yet): New proc.
1185         (build_framework): Add various file commands to file menu.
1186
1187 Fri Dec 23 16:18:50 1994  Stu Grossman  (grossman@cygnus.com)
1188
1189         * gdbtk.c (gdbtk_wait gdbtk_init):  Portability improvements for
1190         SIGIO handling.
1191
1192 Mon Dec 19 09:55:47 1994  Stu Grossman  (grossman@cygnus.com)
1193
1194         * gdbtk.tcl (update_assembly):  Force update to make sure that pc
1195         is visible when creating new assembly windows.
1196
1197 Sun Dec 18 23:31:20 1994  Stu Grossman  (grossman@cygnus.com)
1198
1199         * gdbtk.c (gdbtk_wait gdbtk_init):  Use different method of
1200         enabling I/O interrupts for SVR4 (streams).
1201         * (start_saving_output save_output get_saved_output
1202         finish_saving_output flush_holdbuf gdbtk_flush gdbtk_fputs
1203         gdbtk_init):
1204         Totally revamp to use TCLs dynamic string functions.  Also, quote
1205         all data passed back to TCL to prevent errors with unmatched
1206         braces, odd characters, etc...  This fixes several wierd problems
1207         with outputting strings containing unmatched braces.
1208         * (breakpoint_notify gdb_loc):  Use long hex format to output
1209         addresses of breakpoints and PCs.  This fixes some Alpha problems.
1210         * (breakpoint_notify):  Add stream arg to call to gdbtk_fputs.
1211         * (gdb_listfiles):  Also, go through the symtabs when looking for
1212         files.  This makes xcoff work (sort of), but probably breaks
1213         something else.
1214         * (gdb_stop):  Return TCL_OK instead of nothing.  This fixes odd
1215         TCL errors when hitting stop button.
1216         * (tk_command):  Don't pass interp->result on to Tcl_{Var}Eval, as
1217         that will trash the result.  strdup the result instead and pass
1218         that on.  Improve error handling as well.
1219
1220         * gdbtk.tcl (gdbtk_tcl_flush):  Use global def of
1221         current_output_win.  Makes flushing actually work!
1222         * (asm_win_name create_asm_win update_assembly):  Bunch of fixes
1223         to make assembly windows stop flashing when loading a new file.
1224         * (gdbtk_tcl_busy gdbtk_tcl_idle):  Use catch to prevent gdb_cmd
1225         errors from losing control.
1226         * (create_source_window):  Add source file selection to View menu.
1227         * (create_command_window (<Key-Return> binding):  Quote text fed
1228         into gdb_cmd to prevent eval errors.

1231
1232         * gdbtk.c: Improve mechanism for capturing output values.
1233         (full_filename): Remove.
1234         (gdb_cmd call_wrapper gdbtk_init): Protect all calls from tcl land
1235         with call_wrapper.  This prevents longjmps (usually via error())
1236         from jumping out of tcl/tk and leaving things in an indeterminate
1237         state.
1238         (gdbtk_fputs): Differentiate stdout from stderr when passing text
1239         into tcl land.
1240         * gdbtk.tcl: New view option to disable line numbers.  Put catch
1241         around most uses of gdb_cmd.  Add update button to reg config
1242         window.  Stop doing immediate updates when selecting registers.
1243         Change register view values into checkbuttons.
1244
1245 Mon Dec 12 16:59:29 1994  Stu Grossman  (grossman@cygnus.com)
1246
1247         * gdbtk.tcl (reg_config_menu create_registers_window
1248         recompute_reg_display_list):  Use array instead of individual vars
1249         for register display list.
1250         * (recompute_reg_display_list update_registers):  Fix bug with not
1251         displaying all registers.
1252
1253 Mon Dec 12 12:22:21 1994  Stu Grossman  (grossman@cygnus.com)
1254
1255         * gdbtk.c:  New tcl commands:  gdb_fetch_registers,
1256         gdb_changed_register_list, and gdb_regnames.
1257         * gdbtk.tcl:  Use monochrome color model for now.
1258         * (delete_breakpoint_tag create_file_win):  Add breakdot support.
1259         * (create_file_win create_asm_win update_listing build_framework
1260         create_source_window create_command_window):  Re-org window
1261         creation to give all windows consistent look and feel.
1262         * (update_listing update_asm):  Change pc pointer to '->'.
1263         * (registers_command reg_config_menu create_registers_window
1264         populate_reg_window update_registers):  Revamp register window.
1265         Allow selection of registers to be displayed.  Highlight changed
1266         registers.

1271
1272         * gdbtk.tcl (build_framework):  Add "Report bug" to help menu.
1273
1274         * gdbtk.tcl:  Re-arrange windows using new, consistent layout. Clean
1275         up lots of code and centralize framework initialization.

1291
1292 Tue Nov  1 16:41:12 1994  Stu Grossman  (grossman@cygnus.com)
1293
1294         * Makefile.in:  Use $(objdir)/tcl and $(objdir)/tk if they are
1295         available.
1296         * configure.in (ENABLE_CLIBS):  Use $(TCL) and $(TK) instead of
1297         -ltcl and -ltk.
1298         * gdbtk.c:  Get rid of lots of unnecessary #includes.
1299         * (gdbtk_init):  Use ConnectionNumber macro instead of referencing

1302
1303 Wed Oct 26 15:41:07 1994  Stu Grossman  (grossman@cygnus.com)
1304
1305         * gdbtk.c: Change sense and name of no_windows variable.  Now
1306         called use_windows, and defaults to off (for compatibility).

1313         waits.
1314         * (gdbtk_call_command):  Wrapper around command processing to
1315         alert GUI of target state changes.
1316         * (gdbtk_init):  Get the fd of X server for doing async
1317         notification of X events (via x_event).  Setup new hooks.
1318         * gdbtk.tcl:  Add scrollbars to assembly and command windows.
1319         * Change window foreground & background colors.
1320         * Create margin tag for breakpoints in source and assembly windows.

1322         idle.
1323         * Add start of expression window.
1324         * Change bindings of mouse button 1 in assembly and source window
1325         to just set or clear breakpoints when in the margin tag.
1326         * Change shape of register window to be more vertical to better
1327         reflect its contents.
1328         * Add stop button.
1329         * Cleanup some code around command window bindings.

1340         * (create_file_win):  Use catch to handle open failures more
1341         elegantly.  Also, create special window to display file open
1342         failure message.  Move opening of file prior to creation of text
1343         widget.
1344         * (create_asm_win):  Add PC as argument.  We now base disassembly
1345         on PC instead of function name, since function names can be
1346         ambiguous (usually seen with shared libs).  Also, use catch to
1347         simplify code where we don't care about failures.
