   3         * Moved gdbtk_hooks.c & gdbtk_cmds.c to gdbtk-hooks.c &
   4         gdbtk-cmds.c to comply with the gdb conventions.  Changed the
   5         configure & makefile to reflect the change...

   8
   9         * gdbtk.c: removed all the commands and hooks from this file so
  10         now it contains only the startup code.
  11         * gdbtk.c (gdbtk_init): Fixed a bug in the startup code on Windows
  12         that caused gdbtk not to find the share directory unless
  13         GDBTK_LIBRARY was set.
  14         * gdbtk_cmds.c: New file - this contains all the Tcl commands that
  15         gdb defines.  All the old commands were moved here, the
  16         string-based commands were converted to object commands, and the
  17         object-based commands were all converted to uniformly use the
  18         call_wrapper.  A new function, Gdbtk_Init was added to centralize
  19         initializing the gdb package.
  20         * gdbtk_hooks.c: New file - All the hooks were moved here, and a new
  21         function, gdbtk_add_hooks was added to centralize adding all these
  22         hook functions.  gdbtk_fputs was also modified to handle the new
  23         result_ptr structure.  See the comments in gdbtk.h for more
  24         details.
  25         * gdbtk.h: New file - this contains all the defines and globals
  26         shared by gdbtk.c, gdbtk_cmds.c & gdbtk_hooks.c
  27         * Makefile.in, configure.in & configure: mutatis mutandi for the
  28         new files.

  32
  33         * main.c (main): Don't include gdbtk test code if GDBTK is
  34         not defined by configure.
  35
  36         * configure.in: When enabling gdbtk, add "-DGDBTK" to ENABLE_CFLAGS.
  37

  40 Fri Jun 26 13:56:07 1998  Keith Seitz  <keiths@cygnus.com>
  41
  42         * gdbtk.c: Change all references to static global "interp" to
  43         "gdbtk_interp" and export this global.
  44         (gdbtk_init): If gdbtk_source_filename is not NULL, source this file
  45         into the interpreter when it goes idle.
  46         Add new command "gdb_search".
  47         (gdb_search): New function which searches the symbol table.
  48         (gdbtk_test): New function called by main when the --tclcommand
  49         option is used.
  50
  51         * main.c (main): Add a new option "--tclcommand" which is used
  52         by the testsuite to source a file into the interpreter when it
  53         goes idle.
  54
  55 Wed Jun 17 19:12:23 1998  Jeff Holcomb  <jeffh@cygnus.com>

  58
  59 Mon Jun 15 13:18:21 1998  Jim Ingham <jingham@cygnus.com>
  60
  61         * gdbtk.c (gdbtk_init): Add elements to the auto_path AS LIST
  62         ELEMENTS.  This allows gdbtk to work when installed in a directory
  63         which has a space in the path.  D. Moseley pointed out the bug.
  64
  65
  66 Tue Jun  9 14:10:46 1998  Keith Seitz  <keiths@cygnus.com>

  89         error message from the result to the error_string.

  91         (gdb_actions_command): call validate_actionline when installing the
  92         tracepoint, to do the syntax checking of the actions for us.
  93         - Elena Zannoni  <ezannoni@kwikemart.cygnus.com>
  94         (gdb_get_trace_frame_num): new function to get the
  95         trace frame number from gdb.

  98         (struct wrapped_call_objs): Change the `func' member to
  99         be a Tcl_ObjCmdProc, not an Tcl_CmdProc, since it accepts a vector
 100         of objects as arguments.  Change the object vector to be const,
 101         since that's what all the users of this structure seem to expect.
 102         (call_obj_wrapper): Cast clientData properly before storing it in
 103         the wrapped_args structure.
 104

 111
 112         * configure: Regenerated
 113
 114 Sun May 24 14:00:24 1998  Keith Seitz  <keiths@cygnus.com>
 115
 116         * ser-unix.c (wait_for): Do not reset timeout_remaining for cygwin32 so that
 117         we can use this member to track real timeouts.
 118         (hardwire_readchar): Modify for cygwin32 so that we only ever use a real
 119         system timeout of one second. Track the "real" timeout as a series of these
 120         one second timeouts.
 121         Call ui_loop_hook to keep the gui alive.
 122
 123         * top.c: Define new hook for cygwin32, "ui_loop_hook".
 124
 125         * gdbtk.c (gdbtk_init): Add ui_loop_hook for CygWin32 to work around
 126         update problems.
 127

 134         which was unused.
 135         (_initialize_gdbtk): add cygwin32 specific code to
 136         allow `gdb -nw' to work when specified specified from a windows
 137         console-mode command line.
 138
 139 Wed May 13 11:12:58 1998  James Ingham  <jingham@leda.cygnus.com>
 140
 141         * gdbtk.c: Fixed a goof in the definition of the gdb_get_args &
 142         gdb_get_locals Tcl commands.  Moved the previous ChangeLog entry
 143         from ChangeLog to ChangeLog-gdbtk (here)...
 144
 145 Tue May 12 13:29:20 1998  Jeff Holcomb  <jeffh@cygnus.com>

 151
 152         * gdbtk.c: Add an object call wrapper for the new Tcl_Obj based
 153         commands.  This way the obj commands will also go through
 154         catch_errors.  This is just a bandaid while I rewrite the
 155         string-based commands to use the object format.
 156

1243         * gdbtk.tcl: ENABLE comes back as "1" or "0", not "enable" or

1245         Also, wire up the breakpoint window so that it can be demo'd.
1246
1247 Tue Aug  1 11:44:53 1995  J.T. Conklin  <jtc@rtl.cygnus.com>
1248

1265
1266 Fri May 19 06:15:40 1995  Jim Kingdon  <kingdon@deneb.cygnus.com>
1267
1268         * gdbtk.c: Conditionalize use of stdarg rather than varargs on
1269         ANSI_PROTOTYPES not __STDC__; it must match the definition of
1270         PARAMS.
1271
1272 Thu May 18 15:58:46 1995  J.T. Conklin  <jtc@rtl.cygnus.com>

1285
1286 Tue Apr 11 11:07:12 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
1287
1288         * gdbtk.c (gdbtk_init): If SIOCSPGRP is not available, but

1290
1291 Thu Apr  6 17:00:46 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
1292
1293         * Makefile.in (X11_INCLUDES): Define as empty.
1294         (X11_CFLAGS): Define as including $(X11_INCLUDES).
1295         (X11_LIB_SWITCHES): Define as empty.
1296         (X11_LIBS): Define as -lX11.
1297
1298         * configure.in (enable_gdbtk): If gdbtk, support the --x-includes
1299         and --x-libraries switches, setting the X11_INCLUDES and
1300         X11_LIB_SWITCHES respectively.  Instead of using a hardcoded -lX11
1301         in ENABLE_CLIBS, use the X11_LIB_SWITCHES and X11_LIBS variables.
1302
1303         * gdbtk.c (gdbtk_init): If SIOCSPGRP is not available, don't use
1304         it.  This means that the stop button doesn't work, but is better
1305         than nothing.
1306
1307 Wed Mar 29 17:09:29 1995  Stu Grossman  (grossman@cygnus.com)
1308
1309         * Makefile.in (gdbtk.o):  Use X11_CFLAGS to provide alternate
1310         locations (per-host) for X11 include files.
1311         * config/pa/hppahpux.mh (XM_CLIBS):  Add -L/usr/lib/X11R5 to force
1312         the use of R5 libs.
1313         (X11_CFLAGS):  Add this to indicate the locs
1314         of the R5 include files.
1315
1316 Wed Mar  8 16:12:21 1995  Stu Grossman  (grossman@cygnus.com)

1319         type is not bp_breakpoint.
1320
1321 Tue Feb 14 17:16:41 1995  Stu Grossman  (grossman@cygnus.com)
1322
1323         * gdbtk.c: Ditto.
1324         * gdbtk.c: General cleanups, get rid of unused variables.  Redo
1325         handling of stdout/stderr to just return output as the result of
1326         the tcl command that caused the output.  Cleanup -Wall stuff.
1327         * (breakpoint_notify):  Now returns just action and breakpoint
1328         number.
1329         * (gdb_get_breakpoint_list):  New routine.  Does the obvious.
1330         * (gdb_get_breakpoint_info):  Mostly derived from the old
1331         breakpoint_notify, but returns lots more info.
1332         * (dsprintf_append_element):  Helper routine, works like printf,
1333         but appends a tcl element onto the specified DString.  Good for
1334         building up lists as return values.
1335         * (gdbtk_enable/disable_breakpoint):  Go away.  Replaced with
1336         gdbtk_modify_breakpoint.
1337         * (*many routines*):  Use new result protocol.
1338         * (call_wrapper):  Make sure that recursive calls don't trash results.
1339         * gdbtk.tcl:  New windows, autocmd, and breakpoints.
1340         * (gdbtk_tcl_fputs):  Don't use $current_output_win redirection
1341         anymore.  It's not needed (in fact, this routine may not be needed
1342         anymore).
1343         * (gdbtk_tcl_breakpoint):  Change to reflect new breakpoint
1344         notification protocol.
1345         * (gdbtk_tcl_busy gdbtk_tcl_idle):  Straighten out buttons, remove
1346         catches.
1347         * (interactive_cmd):  Use this wrapper around button invocations
1348         of many commands.  This will catch errors and put the results into
1349         the command window.  It also updates all the other windows.
1350         * Also, change reliefs of most things to sunken.  This actually
1351         looks better.
1352         * (create_file_win):  Fix margin binding to allow breakpoints to
1353         work again.
1354         * (create_asm_win):  Use return value of gdb_disassemble instead
1355         of implicit I/O to the command window.
1356         * (create_command_window):  Use new result protocol to get output
1357         from commands.
1358
1359 Sun Feb  5 20:32:44 1995  Jim Kingdon  (kingdon@lioth.cygnus.com)
1360
1361         * gdbtk.c (gdb_disassemble): Deference pointer to function before
1362         calling it (pre-ANSI compilers generally require this).
1363
1364 Fri Feb  3 11:19:20 1995  Stu Grossman  (grossman@cygnus.com)
1365
1366         * gdbtk.c (gdb_disassemble): Get rid of
1367         dis_asm_read_memory_hook.  We can now call the disassemblers
1368         directly and have no need for this hook anymore.

1419
1420         * gdbtk.c (finish_saving_output):  Don't do anything if not saving
1421         output.
1422         * (breakpoint_notify):  Don't send null filename to tcl.
1423         * (gdb_eval):  New tcl command to eval an expression.
1424         * (gdb_disassemble):  New tcl command to do disassembly.  This
1425         allows tcl code to choose between exec file and target memeory,
1426         and can also do mixed source and assembly.
1427         * (gdbtk_init):  Move reading of gdbtk.tcl to the end to make sure

1445         windows to standard windows menu.
1446         (not_implemented_yet): Clarify message.
1447
1448 Fri Dec 30 15:49:00 1994  Stan Shebs  <shebs@andros.cygnus.com>
1449

1462         is visible when creating new assembly windows.
1463
1464 Sun Dec 18 23:31:20 1994  Stu Grossman  (grossman@cygnus.com)
1465
1466         * gdbtk.c (gdbtk_wait gdbtk_init):  Use different method of
1467         enabling I/O interrupts for SVR4 (streams).
1468         * (start_saving_output save_output get_saved_output
1469         finish_saving_output flush_holdbuf gdbtk_flush gdbtk_fputs
1470         gdbtk_init):
1471         Totally revamp to use TCLs dynamic string functions.  Also, quote
1472         all data passed back to TCL to prevent errors with unmatched
1473         braces, odd characters, etc...  This fixes several wierd problems
1474         with outputting strings containing unmatched braces.
1475         * (breakpoint_notify gdb_loc):  Use long hex format to output
1476         addresses of breakpoints and PCs.  This fixes some Alpha problems.
1477         * (breakpoint_notify):  Add stream arg to call to gdbtk_fputs.
1478         * (gdb_listfiles):  Also, go through the symtabs when looking for
1479         files.  This makes xcoff work (sort of), but probably breaks
1480         something else.
1481         * (gdb_stop):  Return TCL_OK instead of nothing.  This fixes odd
1482         TCL errors when hitting stop button.
1483         * (tk_command):  Don't pass interp->result on to Tcl_{Var}Eval, as
1484         that will trash the result.  strdup the result instead and pass
1485         that on.  Improve error handling as well.
1486
1487         * gdbtk.tcl (gdbtk_tcl_flush):  Use global def of
1488         current_output_win.  Makes flushing actually work!
1489         * (asm_win_name create_asm_win update_assembly):  Bunch of fixes
1490         to make assembly windows stop flashing when loading a new file.
1491         * (gdbtk_tcl_busy gdbtk_tcl_idle):  Use catch to prevent gdb_cmd
1492         errors from losing control.
1493         * (create_source_window):  Add source file selection to View menu.
1494         * (create_command_window (<Key-Return> binding):  Quote text fed
1495         into gdb_cmd to prevent eval errors.

1498
1499         * gdbtk.c: Improve mechanism for capturing output values.
1500         (full_filename): Remove.
1501         (gdb_cmd call_wrapper gdbtk_init): Protect all calls from tcl land
1502         with call_wrapper.  This prevents longjmps (usually via error())
1503         from jumping out of tcl/tk and leaving things in an indeterminate
1504         state.
1505         (gdbtk_fputs): Differentiate stdout from stderr when passing text
1506         into tcl land.
1507         * gdbtk.tcl: New view option to disable line numbers.  Put catch
1508         around most uses of gdb_cmd.  Add update button to reg config
1509         window.  Stop doing immediate updates when selecting registers.
1510         Change register view values into checkbuttons.

1513
1514         * gdbtk.tcl (reg_config_menu create_registers_window
1515         recompute_reg_display_list):  Use array instead of individual vars
1516         for register display list.
1517         * (recompute_reg_display_list update_registers):  Fix bug with not
1518         displaying all registers.
1519
1520 Mon Dec 12 12:22:21 1994  Stu Grossman  (grossman@cygnus.com)

1524         * gdbtk.tcl:  Use monochrome color model for now.
1525         * (delete_breakpoint_tag create_file_win):  Add breakdot support.
1526         * (create_file_win create_asm_win update_listing build_framework
1527         create_source_window create_command_window):  Re-org window
1528         creation to give all windows consistent look and feel.
1529         * (update_listing update_asm):  Change pc pointer to '->'.
1530         * (registers_command reg_config_menu create_registers_window
1531         populate_reg_window update_registers):  Revamp register window.
1532         Allow selection of registers to be displayed.  Highlight changed
1533         registers.

1559 Tue Nov  1 16:41:12 1994  Stu Grossman  (grossman@cygnus.com)
1560
1561         * Makefile.in:  Use $(objdir)/tcl and $(objdir)/tk if they are
1562         available.
1563         * configure.in (ENABLE_CLIBS):  Use $(TCL) and $(TK) instead of
1564         -ltcl and -ltk.
1565         * gdbtk.c:  Get rid of lots of unnecessary #includes.
1566         * (gdbtk_init):  Use ConnectionNumber macro instead of referencing

1580         waits.
1581         * (gdbtk_call_command):  Wrapper around command processing to
1582         alert GUI of target state changes.
1583         * (gdbtk_init):  Get the fd of X server for doing async
1584         notification of X events (via x_event).  Setup new hooks.
1585         * gdbtk.tcl:  Add scrollbars to assembly and command windows.
1586         * Change window foreground & background colors.

1610         widget.
1611         * (create_asm_win):  Add PC as argument.  We now base disassembly
