   3         * gdbtk-cmds.c (gdb_loadfile): When there are no
   4         linenumbers, use only one tab.
   5
   6 Sat Jul 18 12:28:39 1998  Martin M. Hunt  <hunt@cygnus.com>
   7
   8         * gdbtk.c (gdbtk_cleanup): Add call to tcl function
   9         gdbtk_cleanup. We need this so the GUI gets to clean
  10         up no matter how GDB exits.

  12 Wed Jul  1 13:10:58 1998  Jim Ingham   <jingham@cygnus.com>
  13
  14         * Moved gdbtk_hooks.c & gdbtk_cmds.c to gdbtk-hooks.c &
  15         gdbtk-cmds.c to comply with the gdb conventions.  Changed the
  16         configure & makefile to reflect the change...

  18 Wed Jul  1 11:07:21 1998  Jim Ingham   <jingham@cygnus.com>
  19
  20         * gdbtk.c: removed all the commands and hooks from this file so
  21         now it contains only the startup code.
  22         * gdbtk.c (gdbtk_init): Fixed a bug in the startup code on Windows
  23         that caused gdbtk not to find the share directory unless
  24         GDBTK_LIBRARY was set.
  25         * gdbtk_cmds.c: New file - this contains all the Tcl commands that
  26         gdb defines.  All the old commands were moved here, the
  27         string-based commands were converted to object commands, and the
  28         object-based commands were all converted to uniformly use the
  29         call_wrapper.  A new function, Gdbtk_Init was added to centralize
  30         initializing the gdb package.
  31         * gdbtk_hooks.c: New file - All the hooks were moved here, and a new
  32         function, gdbtk_add_hooks was added to centralize adding all these
  33         hook functions.  gdbtk_fputs was also modified to handle the new
  34         result_ptr structure.  See the comments in gdbtk.h for more
  35         details.
  36         * gdbtk.h: New file - this contains all the defines and globals
  37         shared by gdbtk.c, gdbtk_cmds.c & gdbtk_hooks.c
  38         * Makefile.in, configure.in & configure: mutatis mutandi for the
  39         new files.

  42 Mon Jun 29 11:49:17 1998  Keith Seitz  <keiths@cygnus.com>
  43
  44         * main.c (main): Don't include gdbtk test code if GDBTK is
  45         not defined by configure.
  46
  47         * configure.in: When enabling gdbtk, add "-DGDBTK" to ENABLE_CFLAGS.
  48
  49         * configure: Regenerate.
  50
  51 Fri Jun 26 13:56:07 1998  Keith Seitz  <keiths@cygnus.com>
  52
  53         * gdbtk.c: Change all references to static global "interp" to
  54         "gdbtk_interp" and export this global.
  55         (gdbtk_init): If gdbtk_source_filename is not NULL, source this file
  56         into the interpreter when it goes idle.
  57         Add new command "gdb_search".
  58         (gdb_search): New function which searches the symbol table.
  59         (gdbtk_test): New function called by main when the --tclcommand
  60         option is used.
  61
  62         * main.c (main): Add a new option "--tclcommand" which is used
  63         by the testsuite to source a file into the interpreter when it
  64         goes idle.
  65
  66 Wed Jun 17 19:12:23 1998  Jeff Holcomb  <jeffh@cygnus.com>
  67
  68         * Makefile.in (install-only): Install tracing help files.
  69
  70 Mon Jun 15 13:18:21 1998  Jim Ingham <jingham@cygnus.com>
  71
  72         * gdbtk.c (gdbtk_init): Add elements to the auto_path AS LIST
  73         ELEMENTS.  This allows gdbtk to work when installed in a directory
  74         which has a space in the path.  D. Moseley pointed out the bug.
  75
  76
  77 Tue Jun  9 14:10:46 1998  Keith Seitz  <keiths@cygnus.com>

  99         (call_obj_wrapper): in case of error, copy the
 100         error message from the result to the error_string.

 102         (gdb_actions_command): call validate_actionline when installing the
 103         tracepoint, to do the syntax checking of the actions for us.
 104         - Elena Zannoni  <ezannoni@kwikemart.cygnus.com>
 105         (gdb_get_trace_frame_num): new function to get the
 106         trace frame number from gdb.

 109         (struct wrapped_call_objs): Change the `func' member to
 110         be a Tcl_ObjCmdProc, not an Tcl_CmdProc, since it accepts a vector
 111         of objects as arguments.  Change the object vector to be const,
 112         since that's what all the users of this structure seem to expect.
 113         (call_obj_wrapper): Cast clientData properly before storing it in
 114         the wrapped_args structure.
 115

 122
 123         * configure: Regenerated
 124
 125 Sun May 24 14:00:24 1998  Keith Seitz  <keiths@cygnus.com>
 126
 127         * ser-unix.c (wait_for): Do not reset timeout_remaining for cygwin32 so that
 128         we can use this member to track real timeouts.
 129         (hardwire_readchar): Modify for cygwin32 so that we only ever use a real
 130         system timeout of one second. Track the "real" timeout as a series of these
 131         one second timeouts.
 132         Call ui_loop_hook to keep the gui alive.
 133
 134         * top.c: Define new hook for cygwin32, "ui_loop_hook".
 135
 136         * gdbtk.c (gdbtk_init): Add ui_loop_hook for CygWin32 to work around
 137         update problems.
 138

 145         which was unused.
 146         (_initialize_gdbtk): add cygwin32 specific code to
 147         allow `gdb -nw' to work when specified specified from a windows
 148         console-mode command line.
 149
 150 Wed May 13 11:12:58 1998  James Ingham  <jingham@leda.cygnus.com>
 151
 152         * gdbtk.c: Fixed a goof in the definition of the gdb_get_args &
 153         gdb_get_locals Tcl commands.  Moved the previous ChangeLog entry
 154         from ChangeLog to ChangeLog-gdbtk (here)...
 155
 156 Tue May 12 13:29:20 1998  Jeff Holcomb  <jeffh@cygnus.com>
 157
 158         * Makefile.in (install-only): Add images/icons.txt and

 162
 163         * gdbtk.c: Add an object call wrapper for the new Tcl_Obj based
 164         commands.  This way the obj commands will also go through
 165         catch_errors.  This is just a bandaid while I rewrite the
 166         string-based commands to use the object format.
 167
 168 Tue May  5 09:30:25 1998  Christopher Faylor <cgf@cygnus.com>

 194
 195         * gdbtk.c (gdb_loadfile): Change fstat() call to stat().

1254         * gdbtk.tcl: ENABLE comes back as "1" or "0", not "enable" or
1255         "disable".
1256         Also, wire up the breakpoint window so that it can be demo'd.
1257
1258 Tue Aug  1 11:44:53 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
1259

1277 Fri May 19 06:15:40 1995  Jim Kingdon  <kingdon@deneb.cygnus.com>
1278
1279         * gdbtk.c: Conditionalize use of stdarg rather than varargs on
1280         ANSI_PROTOTYPES not __STDC__; it must match the definition of
1281         PARAMS.
1282
1283 Thu May 18 15:58:46 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
1284

1294
1295         * README.GDBTK:  New file.  Contains the obvious.
1296
1297 Tue Apr 11 11:07:12 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
1298
1299         * gdbtk.c (gdbtk_init): If SIOCSPGRP is not available, but
1300         F_SETOWN is, use that.
1301
1302 Thu Apr  6 17:00:46 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
1303
1304         * Makefile.in (X11_INCLUDES): Define as empty.
1305         (X11_CFLAGS): Define as including $(X11_INCLUDES).
1306         (X11_LIB_SWITCHES): Define as empty.
1307         (X11_LIBS): Define as -lX11.
1308
1309         * configure.in (enable_gdbtk): If gdbtk, support the --x-includes
1310         and --x-libraries switches, setting the X11_INCLUDES and
1311         X11_LIB_SWITCHES respectively.  Instead of using a hardcoded -lX11
1312         in ENABLE_CLIBS, use the X11_LIB_SWITCHES and X11_LIBS variables.
1313
1314         * gdbtk.c (gdbtk_init): If SIOCSPGRP is not available, don't use
1315         it.  This means that the stop button doesn't work, but is better
1316         than nothing.
1317
1318 Wed Mar 29 17:09:29 1995  Stu Grossman  (grossman@cygnus.com)
1319
1320         * Makefile.in (gdbtk.o):  Use X11_CFLAGS to provide alternate
1321         locations (per-host) for X11 include files.
1322         * config/pa/hppahpux.mh (XM_CLIBS):  Add -L/usr/lib/X11R5 to force
1323         the use of R5 libs.
1324         (X11_CFLAGS):  Add this to indicate the locs
1325         of the R5 include files.
1326
1327 Wed Mar  8 16:12:21 1995  Stu Grossman  (grossman@cygnus.com)
1328
1329         * gdbtk.c (gdb_get_breakpoint_info):  Return error if breakpoint
1330         type is not bp_breakpoint.
1331
1332 Tue Feb 14 17:16:41 1995  Stu Grossman  (grossman@cygnus.com)
1333
1334         * gdbtk.c: Ditto.
1335         * gdbtk.c: General cleanups, get rid of unused variables.  Redo
1336         handling of stdout/stderr to just return output as the result of
1337         the tcl command that caused the output.  Cleanup -Wall stuff.
1338         * (breakpoint_notify):  Now returns just action and breakpoint
1339         number.
1340         * (gdb_get_breakpoint_list):  New routine.  Does the obvious.
1341         * (gdb_get_breakpoint_info):  Mostly derived from the old
1342         breakpoint_notify, but returns lots more info.
1343         * (dsprintf_append_element):  Helper routine, works like printf,
1344         but appends a tcl element onto the specified DString.  Good for
1345         building up lists as return values.
1346         * (gdbtk_enable/disable_breakpoint):  Go away.  Replaced with
1347         gdbtk_modify_breakpoint.
1348         * (*many routines*):  Use new result protocol.
1349         * (call_wrapper):  Make sure that recursive calls don't trash results.
1350         * gdbtk.tcl:  New windows, autocmd, and breakpoints.
1351         * (gdbtk_tcl_fputs):  Don't use $current_output_win redirection
1352         anymore.  It's not needed (in fact, this routine may not be needed
1353         anymore).
1354         * (gdbtk_tcl_breakpoint):  Change to reflect new breakpoint
1355         notification protocol.
1356         * (gdbtk_tcl_busy gdbtk_tcl_idle):  Straighten out buttons, remove
1357         catches.
1358         * (interactive_cmd):  Use this wrapper around button invocations
1359         of many commands.  This will catch errors and put the results into
1360         the command window.  It also updates all the other windows.
1361         * Also, change reliefs of most things to sunken.  This actually
1362         looks better.
1363         * (create_file_win):  Fix margin binding to allow breakpoints to
1364         work again.
1365         * (create_asm_win):  Use return value of gdb_disassemble instead
1366         of implicit I/O to the command window.
1367         * (create_command_window):  Use new result protocol to get output
1368         from commands.
1369
1370 Sun Feb  5 20:32:44 1995  Jim Kingdon  (kingdon@lioth.cygnus.com)
1371
1372         * gdbtk.c (gdb_disassemble): Deference pointer to function before
1373         calling it (pre-ANSI compilers generally require this).
1374
1375 Fri Feb  3 11:19:20 1995  Stu Grossman  (grossman@cygnus.com)
1376
1377         * gdbtk.c (gdb_disassemble): Get rid of
1378         dis_asm_read_memory_hook.  We can now call the disassemblers

1430
1431         * gdbtk.c (finish_saving_output):  Don't do anything if not saving
1432         output.
1433         * (breakpoint_notify):  Don't send null filename to tcl.
1434         * (gdb_eval):  New tcl command to eval an expression.
1435         * (gdb_disassemble):  New tcl command to do disassembly.  This
1436         allows tcl code to choose between exec file and target memeory,
1437         and can also do mixed source and assembly.
1438         * (gdbtk_init):  Move reading of gdbtk.tcl to the end to make sure

1456         windows to standard windows menu.
1457         (not_implemented_yet): Clarify message.
1458
1459 Fri Dec 30 15:49:00 1994  Stan Shebs  <shebs@andros.cygnus.com>
1460

1474
1475 Sun Dec 18 23:31:20 1994  Stu Grossman  (grossman@cygnus.com)
1476
1477         * gdbtk.c (gdbtk_wait gdbtk_init):  Use different method of
1478         enabling I/O interrupts for SVR4 (streams).
1479         * (start_saving_output save_output get_saved_output
1480         finish_saving_output flush_holdbuf gdbtk_flush gdbtk_fputs
1481         gdbtk_init):
1482         Totally revamp to use TCLs dynamic string functions.  Also, quote
1483         all data passed back to TCL to prevent errors with unmatched
1484         braces, odd characters, etc...  This fixes several wierd problems
1485         with outputting strings containing unmatched braces.
1486         * (breakpoint_notify gdb_loc):  Use long hex format to output
1487         addresses of breakpoints and PCs.  This fixes some Alpha problems.
1488         * (breakpoint_notify):  Add stream arg to call to gdbtk_fputs.
1489         * (gdb_listfiles):  Also, go through the symtabs when looking for
1490         files.  This makes xcoff work (sort of), but probably breaks
1491         something else.
1492         * (gdb_stop):  Return TCL_OK instead of nothing.  This fixes odd
1493         TCL errors when hitting stop button.
1494         * (tk_command):  Don't pass interp->result on to Tcl_{Var}Eval, as
1495         that will trash the result.  strdup the result instead and pass
1496         that on.  Improve error handling as well.
1497
1498         * gdbtk.tcl (gdbtk_tcl_flush):  Use global def of
1499         current_output_win.  Makes flushing actually work!
1500         * (asm_win_name create_asm_win update_assembly):  Bunch of fixes
1501         to make assembly windows stop flashing when loading a new file.
1502         * (gdbtk_tcl_busy gdbtk_tcl_idle):  Use catch to prevent gdb_cmd
1503         errors from losing control.
1504         * (create_source_window):  Add source file selection to View menu.
1505         * (create_command_window (<Key-Return> binding):  Quote text fed
1506         into gdb_cmd to prevent eval errors.

1509
1510         * gdbtk.c: Improve mechanism for capturing output values.
1511         (full_filename): Remove.
1512         (gdb_cmd call_wrapper gdbtk_init): Protect all calls from tcl land
1513         with call_wrapper.  This prevents longjmps (usually via error())
1514         from jumping out of tcl/tk and leaving things in an indeterminate
1515         state.
1516         (gdbtk_fputs): Differentiate stdout from stderr when passing text
1517         into tcl land.
1518         * gdbtk.tcl: New view option to disable line numbers.  Put catch
1519         around most uses of gdb_cmd.  Add update button to reg config
1520         window.  Stop doing immediate updates when selecting registers.
1521         Change register view values into checkbuttons.

1525         * gdbtk.tcl (reg_config_menu create_registers_window
1526         recompute_reg_display_list):  Use array instead of individual vars
1527         for register display list.
1528         * (recompute_reg_display_list update_registers):  Fix bug with not
1529         displaying all registers.
1530

1535         * gdbtk.tcl:  Use monochrome color model for now.
1536         * (delete_breakpoint_tag create_file_win):  Add breakdot support.
1537         * (create_file_win create_asm_win update_listing build_framework
1538         create_source_window create_command_window):  Re-org window
1539         creation to give all windows consistent look and feel.
1540         * (update_listing update_asm):  Change pc pointer to '->'.
1541         * (registers_command reg_config_menu create_registers_window
1542         populate_reg_window update_registers):  Revamp register window.
1543         Allow selection of registers to be displayed.  Highlight changed
1544         registers.

1570 Tue Nov  1 16:41:12 1994  Stu Grossman  (grossman@cygnus.com)
1571
1572         * Makefile.in:  Use $(objdir)/tcl and $(objdir)/tk if they are
1573         available.
1574         * configure.in (ENABLE_CLIBS):  Use $(TCL) and $(TK) instead of
1575         -ltcl and -ltk.
1576         * gdbtk.c:  Get rid of lots of unnecessary #includes.
1577         * (gdbtk_init):  Use ConnectionNumber macro instead of referencing

1591         waits.
1592         * (gdbtk_call_command):  Wrapper around command processing to
1593         alert GUI of target state changes.
1594         * (gdbtk_init):  Get the fd of X server for doing async
1595         notification of X events (via x_event).  Setup new hooks.
1596         * gdbtk.tcl:  Add scrollbars to assembly and command windows.
1597         * Change window foreground & background colors.

1603         to just set or clear breakpoints when in the margin tag.
1604         * Change shape of register window to be more vertical to better
1605         reflect its contents.
1606         * Add stop button.
1607         * Cleanup some code around command window bindings.

1621         widget.
1622         * (create_asm_win):  Add PC as argument.  We now base disassembly
1623         on PC instead of function name, since function names can be
