   2
   3         * gdbtk.c (gdbtk_call_command): Removed because it is now
   4         in gdbtk-hooks.c
   5         (null_routine): Removed.
   6
   7         * gdbtk-hooks.c (tracepoint_notify): Fix sprintf to
   8         match number of arguments.
   9
  10         * gdbtk-cmds.c (gdb_loc): When calling gdb_loc with an
  11         argument, call find_pc_line() to get a complete
  12         symtab_and_line struct.
  13
  14 Fri Jul 24 14:25:43 1998  Keith Seitz  <keiths@cygnus.com>
  15
  16         * gdbtk-cmds.c (gdb_search): Add missing NULL to switches.
  17         Add missing flags to result_ptr.
  18         Pass along any errors caused by getting the list of files from
  19         tcl.
  20         Allocate correct amount of memory for the file list.

  22
  23 Fri Jul 24 01:08:37 1998  Martin M. Hunt  <hunt@cygnus.com>
  24
  25         * gdbtk-cmds.c (gdb_loadfile): When there are no

  27
  28 Sat Jul 18 12:28:39 1998  Martin M. Hunt  <hunt@cygnus.com>
  29
  30         * gdbtk.c (gdbtk_cleanup): Add call to tcl function
  31         gdbtk_cleanup. We need this so the GUI gets to clean
  32         up no matter how GDB exits.
  33
  34 Wed Jul  1 13:10:58 1998  Jim Ingham   <jingham@cygnus.com>
  35
  36         * Moved gdbtk_hooks.c & gdbtk_cmds.c to gdbtk-hooks.c &
  37         gdbtk-cmds.c to comply with the gdb conventions.  Changed the
  38         configure & makefile to reflect the change...
  39
  40 Wed Jul  1 11:07:21 1998  Jim Ingham   <jingham@cygnus.com>
  41
  42         * gdbtk.c: removed all the commands and hooks from this file so
  43         now it contains only the startup code.
  44         * gdbtk.c (gdbtk_init): Fixed a bug in the startup code on Windows
  45         that caused gdbtk not to find the share directory unless
  46         GDBTK_LIBRARY was set.
  47         * gdbtk_cmds.c: New file - this contains all the Tcl commands that
  48         gdb defines.  All the old commands were moved here, the
  49         string-based commands were converted to object commands, and the
  50         object-based commands were all converted to uniformly use the
  51         call_wrapper.  A new function, Gdbtk_Init was added to centralize
  52         initializing the gdb package.
  53         * gdbtk_hooks.c: New file - All the hooks were moved here, and a new
  54         function, gdbtk_add_hooks was added to centralize adding all these
  55         hook functions.  gdbtk_fputs was also modified to handle the new
  56         result_ptr structure.  See the comments in gdbtk.h for more
  57         details.
  58         * gdbtk.h: New file - this contains all the defines and globals
  59         shared by gdbtk.c, gdbtk_cmds.c & gdbtk_hooks.c
  60         * Makefile.in, configure.in & configure: mutatis mutandi for the
  61         new files.

  63
  64 Mon Jun 29 11:49:17 1998  Keith Seitz  <keiths@cygnus.com>
  65
  66         * main.c (main): Don't include gdbtk test code if GDBTK is
  67         not defined by configure.
  68
  69         * configure.in: When enabling gdbtk, add "-DGDBTK" to ENABLE_CFLAGS.
  70
  71         * configure: Regenerate.
  72
  73 Fri Jun 26 13:56:07 1998  Keith Seitz  <keiths@cygnus.com>
  74
  75         * gdbtk.c: Change all references to static global "interp" to
  76         "gdbtk_interp" and export this global.
  77         (gdbtk_init): If gdbtk_source_filename is not NULL, source this file
  78         into the interpreter when it goes idle.
  79         Add new command "gdb_search".
  80         (gdb_search): New function which searches the symbol table.
  81         (gdbtk_test): New function called by main when the --tclcommand
  82         option is used.
  83
  84         * main.c (main): Add a new option "--tclcommand" which is used
  85         by the testsuite to source a file into the interpreter when it
  86         goes idle.
  87
  88 Wed Jun 17 19:12:23 1998  Jeff Holcomb  <jeffh@cygnus.com>
  89
  90         * Makefile.in (install-only): Install tracing help files.
  91
  92 Mon Jun 15 13:18:21 1998  Jim Ingham <jingham@cygnus.com>
  93
  94         * gdbtk.c (gdbtk_init): Add elements to the auto_path AS LIST
  95         ELEMENTS.  This allows gdbtk to work when installed in a directory
  96         which has a space in the path.  D. Moseley pointed out the bug.
  97
  98
  99 Tue Jun  9 14:10:46 1998  Keith Seitz  <keiths@cygnus.com>

 121         (call_obj_wrapper): in case of error, copy the
 122         error message from the result to the error_string.
 123         (gdbtk_fputs): add comments.
 124         (gdb_actions_command): call validate_actionline when installing the
 125         tracepoint, to do the syntax checking of the actions for us.
 126         - Elena Zannoni  <ezannoni@kwikemart.cygnus.com>
 127         (gdb_get_trace_frame_num): new function to get the
 128         trace frame number from gdb.

 131         (struct wrapped_call_objs): Change the `func' member to
 132         be a Tcl_ObjCmdProc, not an Tcl_CmdProc, since it accepts a vector
 133         of objects as arguments.  Change the object vector to be const,
 134         since that's what all the users of this structure seem to expect.
 135         (call_obj_wrapper): Cast clientData properly before storing it in
 136         the wrapped_args structure.
 137
 138 Thu May 28 17:19:14 1998  Keith Seitz  <keiths@cygnus.com>

 144
 145         * configure: Regenerated
 146
 147 Sun May 24 14:00:24 1998  Keith Seitz  <keiths@cygnus.com>
 148
 149         * ser-unix.c (wait_for): Do not reset timeout_remaining for cygwin32 so that
 150         we can use this member to track real timeouts.
 151         (hardwire_readchar): Modify for cygwin32 so that we only ever use a real
 152         system timeout of one second. Track the "real" timeout as a series of these
 153         one second timeouts.
 154         Call ui_loop_hook to keep the gui alive.
 155
 156         * top.c: Define new hook for cygwin32, "ui_loop_hook".
 157
 158         * gdbtk.c (gdbtk_init): Add ui_loop_hook for CygWin32 to work around
 159         update problems.
 160
 161 Thu May 21 13:56:24 1998  Elena Zannoni  <ezannoni@kwikemart.cygnus.com>

 165         cygwin-specific call (cosmetic change).
 166         (gdbtk_ignorable_warning): removed va_list parameter,
 167         which was unused.
 168         (_initialize_gdbtk): add cygwin32 specific code to
 169         allow `gdb -nw' to work when specified specified from a windows
 170         console-mode command line.
 171
 172 Wed May 13 11:12:58 1998  James Ingham  <jingham@leda.cygnus.com>
 173
 174         * gdbtk.c: Fixed a goof in the definition of the gdb_get_args &
 175         gdb_get_locals Tcl commands.  Moved the previous ChangeLog entry
 176         from ChangeLog to ChangeLog-gdbtk (here)...
 177
 178 Tue May 12 13:29:20 1998  Jeff Holcomb  <jeffh@cygnus.com>
 179
 180         * Makefile.in (install-only): Add images/icons.txt and

 184
 185         * gdbtk.c: Add an object call wrapper for the new Tcl_Obj based
 186         commands.  This way the obj commands will also go through
 187         catch_errors.  This is just a bandaid while I rewrite the
 188         string-based commands to use the object format.
 189
 190 Tue May  5 09:30:25 1998  Christopher Faylor <cgf@cygnus.com>

 216
 217         * gdbtk.c (gdb_loadfile): Change fstat() call to stat().

1300
1301         * gdbtk.c: Conditionalize use of stdarg rather than varargs on

1325
1326         * Makefile.in (X11_INCLUDES): Define as empty.
1327         (X11_CFLAGS): Define as including $(X11_INCLUDES).
1328         (X11_LIB_SWITCHES): Define as empty.
1329         (X11_LIBS): Define as -lX11.
1330
1331         * configure.in (enable_gdbtk): If gdbtk, support the --x-includes
1332         and --x-libraries switches, setting the X11_INCLUDES and
1333         X11_LIB_SWITCHES respectively.  Instead of using a hardcoded -lX11
1334         in ENABLE_CLIBS, use the X11_LIB_SWITCHES and X11_LIBS variables.
1335
1336         * gdbtk.c (gdbtk_init): If SIOCSPGRP is not available, don't use

1339
1340 Wed Mar 29 17:09:29 1995  Stu Grossman  (grossman@cygnus.com)

1347         of the R5 include files.

1353

1355
1356         * gdbtk.c: Ditto.
1357         * gdbtk.c: General cleanups, get rid of unused variables.  Redo
1358         handling of stdout/stderr to just return output as the result of
1359         the tcl command that caused the output.  Cleanup -Wall stuff.
1360         * (breakpoint_notify):  Now returns just action and breakpoint
1361         number.
1362         * (gdb_get_breakpoint_list):  New routine.  Does the obvious.

1364         breakpoint_notify, but returns lots more info.
1365         * (dsprintf_append_element):  Helper routine, works like printf,
1366         but appends a tcl element onto the specified DString.  Good for
1367         building up lists as return values.
1368         * (gdbtk_enable/disable_breakpoint):  Go away.  Replaced with
1369         gdbtk_modify_breakpoint.
1370         * (*many routines*):  Use new result protocol.

1372         * gdbtk.tcl:  New windows, autocmd, and breakpoints.
1373         * (gdbtk_tcl_fputs):  Don't use $current_output_win redirection
1374         anymore.  It's not needed (in fact, this routine may not be needed
1375         anymore).
1376         * (gdbtk_tcl_breakpoint):  Change to reflect new breakpoint
1377         notification protocol.
1378         * (gdbtk_tcl_busy gdbtk_tcl_idle):  Straighten out buttons, remove
1379         catches.
1380         * (interactive_cmd):  Use this wrapper around button invocations
1381         of many commands.  This will catch errors and put the results into
1382         the command window.  It also updates all the other windows.
1383         * Also, change reliefs of most things to sunken.  This actually
1384         looks better.
1385         * (create_file_win):  Fix margin binding to allow breakpoints to
1386         work again.
1387         * (create_asm_win):  Use return value of gdb_disassemble instead
1388         of implicit I/O to the command window.
1389         * (create_command_window):  Use new result protocol to get output
1390         from commands.

1393
1394         * gdbtk.c (gdb_disassemble): Deference pointer to function before
1395         calling it (pre-ANSI compilers generally require this).
1396
1397 Fri Feb  3 11:19:20 1995  Stu Grossman  (grossman@cygnus.com)
1398
1399         * gdbtk.c (gdb_disassemble): Get rid of
1400         dis_asm_read_memory_hook.  We can now call the disassemblers

1418         widget bug to make Options|Natural button work.
1419
1420         * gdbtk.c (gdb_disassemble):  Fix problem with source+assembly and
1421         g++ caused by out-of-order pc's.
1422         * gdbtk.tcl (files_command):  Remove duplicate file names.  Also,
1423         add scrollbar.

1452
1453         * gdbtk.c (finish_saving_output):  Don't do anything if not saving
1454         output.
1455         * (breakpoint_notify):  Don't send null filename to tcl.
1456         * (gdb_eval):  New tcl command to eval an expression.
1457         * (gdb_disassemble):  New tcl command to do disassembly.  This
1458         allows tcl code to choose between exec file and target memeory,
1459         and can also do mixed source and assembly.
1460         * (gdbtk_init):  Move reading of gdbtk.tcl to the end to make sure
1461         that more of the environment is set up.  Also, create link between
1462         gdb and tcl vars disassemble{-_}from{-_}exec.
1463
1464         * gdbtk.tcl:  New expression window support.
1465         * Make assembly window be 80 columns wide.

1478         windows to standard windows menu.
1479         (not_implemented_yet): Clarify message.
1480
1481 Fri Dec 30 15:49:00 1994  Stan Shebs  <shebs@andros.cygnus.com>

1496
1497 Sun Dec 18 23:31:20 1994  Stu Grossman  (grossman@cygnus.com)
1498
1499         * gdbtk.c (gdbtk_wait gdbtk_init):  Use different method of
1500         enabling I/O interrupts for SVR4 (streams).
1501         * (start_saving_output save_output get_saved_output
1502         finish_saving_output flush_holdbuf gdbtk_flush gdbtk_fputs
1503         gdbtk_init):
1504         Totally revamp to use TCLs dynamic string functions.  Also, quote
1505         all data passed back to TCL to prevent errors with unmatched
1506         braces, odd characters, etc...  This fixes several wierd problems
1507         with outputting strings containing unmatched braces.
1508         * (breakpoint_notify gdb_loc):  Use long hex format to output
1509         addresses of breakpoints and PCs.  This fixes some Alpha problems.
1510         * (breakpoint_notify):  Add stream arg to call to gdbtk_fputs.
1511         * (gdb_listfiles):  Also, go through the symtabs when looking for
1512         files.  This makes xcoff work (sort of), but probably breaks
1513         something else.
1514         * (gdb_stop):  Return TCL_OK instead of nothing.  This fixes odd
1515         TCL errors when hitting stop button.
1516         * (tk_command):  Don't pass interp->result on to Tcl_{Var}Eval, as
1517         that will trash the result.  strdup the result instead and pass
1518         that on.  Improve error handling as well.
1519
1520         * gdbtk.tcl (gdbtk_tcl_flush):  Use global def of
1521         current_output_win.  Makes flushing actually work!
1522         * (asm_win_name create_asm_win update_assembly):  Bunch of fixes
1523         to make assembly windows stop flashing when loading a new file.
1524         * (gdbtk_tcl_busy gdbtk_tcl_idle):  Use catch to prevent gdb_cmd
1525         errors from losing control.
1526         * (create_source_window):  Add source file selection to View menu.
1527         * (create_command_window (<Key-Return> binding):  Quote text fed
1528         into gdb_cmd to prevent eval errors.

1531
1532         * gdbtk.c: Improve mechanism for capturing output values.
1533         (full_filename): Remove.
1534         (gdb_cmd call_wrapper gdbtk_init): Protect all calls from tcl land
1535         with call_wrapper.  This prevents longjmps (usually via error())
1536         from jumping out of tcl/tk and leaving things in an indeterminate
1537         state.
1538         (gdbtk_fputs): Differentiate stdout from stderr when passing text
1539         into tcl land.
1540         * gdbtk.tcl: New view option to disable line numbers.  Put catch
1541         around most uses of gdb_cmd.  Add update button to reg config
1542         window.  Stop doing immediate updates when selecting registers.
1543         Change register view values into checkbuttons.

1547         * gdbtk.tcl (reg_config_menu create_registers_window
1548         recompute_reg_display_list):  Use array instead of individual vars
1549         for register display list.
1550         * (recompute_reg_display_list update_registers):  Fix bug with not
1551         displaying all registers.
1552
1553 Mon Dec 12 12:22:21 1994  Stu Grossman  (grossman@cygnus.com)

1557         * gdbtk.tcl:  Use monochrome color model for now.
1558         * (delete_breakpoint_tag create_file_win):  Add breakdot support.
1559         * (create_file_win create_asm_win update_listing build_framework
1560         create_source_window create_command_window):  Re-org window
1561         creation to give all windows consistent look and feel.
1562         * (update_listing update_asm):  Change pc pointer to '->'.
1563         * (registers_command reg_config_menu create_registers_window
1564         populate_reg_window update_registers):  Revamp register window.
1565         Allow selection of registers to be displayed.  Highlight changed
1566         registers.

1592 Tue Nov  1 16:41:12 1994  Stu Grossman  (grossman@cygnus.com)
1593
1594         * Makefile.in:  Use $(objdir)/tcl and $(objdir)/tk if they are
1595         available.
1596         * configure.in (ENABLE_CLIBS):  Use $(TCL) and $(TK) instead of
1597         -ltcl and -ltk.
1598         * gdbtk.c:  Get rid of lots of unnecessary #includes.
1599         * (gdbtk_init):  Use ConnectionNumber macro instead of referencing

1613         waits.
1614         * (gdbtk_call_command):  Wrapper around command processing to
1615         alert GUI of target state changes.
1616         * (gdbtk_init):  Get the fd of X server for doing async
1617         notification of X events (via x_event).  Setup new hooks.
1618         * gdbtk.tcl:  Add scrollbars to assembly and command windows.
1619         * Change window foreground & background colors.
1620         * Create margin tag for breakpoints in source and assembly windows.

1626         * Change shape of register window to be more vertical to better
1627         reflect its contents.
1628         * Add stop button.
1629         * Cleanup some code around command window bindings.

1643         widget.
1644         * (create_asm_win):  Add PC as argument.  We now base disassembly
1645         on PC instead of function name, since function names can be
