   3
   4         * Makefile.in (FOUNDRY_LIB_BASE): Added the Foundry SDK code that allows
   5         gdbtk to be linked with the Foundry libraries provided by a prebuilt/released
   6         binary version of Foundry.  The libraries and header files need to come from
   7         the installed location of Foundry rather than the devo subdirectories.
   8         * configure.in (ENABLE_IDE): Foundry SDK additions.  Added the "with-foundry-libs"
   9         configure option.
  10         * configure: Foundry SDK additions.  Regenerated from configure.in.

  13 Thu Aug 13 15:09:59 1998  Drew Moseley  <dmoseley@cygnus.com>
  14
  15         * gdbtk.c (gdbtk_cleanup): added a scope-level around the contents
  16         of the #ifdef so that the variable declarations in there would not
  17         be illegal in a C compilation.
  18
  19 Mon Jul 27 13:07:16 1998  Martin M. Hunt  <hunt@cygnus.com>
  20
  21         * gdbtk.c (gdbtk_call_command): Removed because it is now
  22         in gdbtk-hooks.c
  23         (null_routine): Removed.
  24
  25         * gdbtk-hooks.c (tracepoint_notify): Fix sprintf to
  26         match number of arguments.
  27
  28         * gdbtk-cmds.c (gdb_loc): When calling gdb_loc with an
  29         argument, call find_pc_line() to get a complete
  30         symtab_and_line struct.
  31
  32 Fri Jul 24 14:25:43 1998  Keith Seitz  <keiths@cygnus.com>
  33
  34         * gdbtk-cmds.c (gdb_search): Add missing NULL to switches.
  35         Add missing flags to result_ptr.
  36         Pass along any errors caused by getting the list of files from
  37         tcl.
  38         Allocate correct amount of memory for the file list.
  39         Don't do any unecessary cleanups.
  40
  41 Fri Jul 24 01:08:37 1998  Martin M. Hunt  <hunt@cygnus.com>
  42
  43         * gdbtk-cmds.c (gdb_loadfile): When there are no
  44         linenumbers, use only one tab.
  45
  46 Sat Jul 18 12:28:39 1998  Martin M. Hunt  <hunt@cygnus.com>
  47
  48         * gdbtk.c (gdbtk_cleanup): Add call to tcl function
  49         gdbtk_cleanup. We need this so the GUI gets to clean
  50         up no matter how GDB exits.
  51
  52 Wed Jul  1 13:10:58 1998  Jim Ingham   <jingham@cygnus.com>
  53
  54         * Moved gdbtk_hooks.c & gdbtk_cmds.c to gdbtk-hooks.c &
  55         gdbtk-cmds.c to comply with the gdb conventions.  Changed the
  56         configure & makefile to reflect the change...
  57
  58 Wed Jul  1 11:07:21 1998  Jim Ingham   <jingham@cygnus.com>
  59
  60         * gdbtk.c: removed all the commands and hooks from this file so
  61         now it contains only the startup code.
  62         * gdbtk.c (gdbtk_init): Fixed a bug in the startup code on Windows
  63         that caused gdbtk not to find the share directory unless
  64         GDBTK_LIBRARY was set.
  65         * gdbtk_cmds.c: New file - this contains all the Tcl commands that
  66         gdb defines.  All the old commands were moved here, the
  67         string-based commands were converted to object commands, and the
  68         object-based commands were all converted to uniformly use the
  69         call_wrapper.  A new function, Gdbtk_Init was added to centralize
  70         initializing the gdb package.
  71         * gdbtk_hooks.c: New file - All the hooks were moved here, and a new
  72         function, gdbtk_add_hooks was added to centralize adding all these
  73         hook functions.  gdbtk_fputs was also modified to handle the new
  74         result_ptr structure.  See the comments in gdbtk.h for more
  75         details.
  76         * gdbtk.h: New file - this contains all the defines and globals
  77         shared by gdbtk.c, gdbtk_cmds.c & gdbtk_hooks.c
  78         * Makefile.in, configure.in & configure: mutatis mutandi for the
  79         new files.

  81
  82 Mon Jun 29 11:49:17 1998  Keith Seitz  <keiths@cygnus.com>
  83
  84         * main.c (main): Don't include gdbtk test code if GDBTK is
  85         not defined by configure.
  86
  87         * configure.in: When enabling gdbtk, add "-DGDBTK" to ENABLE_CFLAGS.
  88
  89         * configure: Regenerate.
  90
  91 Fri Jun 26 13:56:07 1998  Keith Seitz  <keiths@cygnus.com>
  92
  93         * gdbtk.c: Change all references to static global "interp" to
  94         "gdbtk_interp" and export this global.
  95         (gdbtk_init): If gdbtk_source_filename is not NULL, source this file
  96         into the interpreter when it goes idle.
  97         Add new command "gdb_search".
  98         (gdb_search): New function which searches the symbol table.
  99         (gdbtk_test): New function called by main when the --tclcommand
 100         option is used.
 101
 102         * main.c (main): Add a new option "--tclcommand" which is used
 103         by the testsuite to source a file into the interpreter when it
 104         goes idle.
 105
 106 Wed Jun 17 19:12:23 1998  Jeff Holcomb  <jeffh@cygnus.com>
 107
 108         * Makefile.in (install-only): Install tracing help files.
 109
 110 Mon Jun 15 13:18:21 1998  Jim Ingham <jingham@cygnus.com>
 111
 112         * gdbtk.c (gdbtk_init): Add elements to the auto_path AS LIST
 113         ELEMENTS.  This allows gdbtk to work when installed in a directory
 114         which has a space in the path.  D. Moseley pointed out the bug.
 115
 116
 117 Tue Jun  9 14:10:46 1998  Keith Seitz  <keiths@cygnus.com>

 119         * gdbtk.c (gdb_get_vars_command): Return static variables and
 120         variables stored in registers.
 121

 139         (call_obj_wrapper): in case of error, copy the
 140         error message from the result to the error_string.
 141         (gdbtk_fputs): add comments.
 142         (gdb_actions_command): call validate_actionline when installing the
 143         tracepoint, to do the syntax checking of the actions for us.
 144         - Elena Zannoni  <ezannoni@kwikemart.cygnus.com>
 145         (gdb_get_trace_frame_num): new function to get the
 146         trace frame number from gdb.

 149         (struct wrapped_call_objs): Change the `func' member to
 150         be a Tcl_ObjCmdProc, not an Tcl_CmdProc, since it accepts a vector
 151         of objects as arguments.  Change the object vector to be const,
 152         since that's what all the users of this structure seem to expect.
 153         (call_obj_wrapper): Cast clientData properly before storing it in
 154         the wrapped_args structure.
 155
 156 Thu May 28 17:19:14 1998  Keith Seitz  <keiths@cygnus.com>

 162
 163         * configure: Regenerated
 164
 165 Sun May 24 14:00:24 1998  Keith Seitz  <keiths@cygnus.com>
 166
 167         * ser-unix.c (wait_for): Do not reset timeout_remaining for cygwin32 so that
 168         we can use this member to track real timeouts.
 169         (hardwire_readchar): Modify for cygwin32 so that we only ever use a real
 170         system timeout of one second. Track the "real" timeout as a series of these
 171         one second timeouts.
 172         Call ui_loop_hook to keep the gui alive.
 173
 174         * top.c: Define new hook for cygwin32, "ui_loop_hook".
 175
 176         * gdbtk.c (gdbtk_init): Add ui_loop_hook for CygWin32 to work around
 177         update problems.
 178
 179 Thu May 21 13:56:24 1998  Elena Zannoni  <ezannoni@kwikemart.cygnus.com>
 180

 183         cygwin-specific call (cosmetic change).
 184         (gdbtk_ignorable_warning): removed va_list parameter,
 185         which was unused.
 186         (_initialize_gdbtk): add cygwin32 specific code to
 187         allow `gdb -nw' to work when specified specified from a windows
 188         console-mode command line.
 189
 190 Wed May 13 11:12:58 1998  James Ingham  <jingham@leda.cygnus.com>
 191
 192         * gdbtk.c: Fixed a goof in the definition of the gdb_get_args &
 193         gdb_get_locals Tcl commands.  Moved the previous ChangeLog entry
 194         from ChangeLog to ChangeLog-gdbtk (here)...
 195
 196 Tue May 12 13:29:20 1998  Jeff Holcomb  <jeffh@cygnus.com>
 197
 198         * Makefile.in (install-only): Add images/icons.txt and
 199         images2/icons.txt to files that need to be installed.
 200
 201 Tue May 12 12:03:16 1998  James Ingham  <jingham@leda.cygnus.com>
 202
 203         * gdbtk.c: Add an object call wrapper for the new Tcl_Obj based
 204         commands.  This way the obj commands will also go through
 205         catch_errors.  This is just a bandaid while I rewrite the
 206         string-based commands to use the object format.
 207
 208 Tue May  5 09:30:25 1998  Christopher Faylor <cgf@cygnus.com>

 234
 235         * gdbtk.c (gdb_loadfile): Change fstat() call to stat().

 244         (gdbtk_ignorable_warning) new function to pass a warning
 245         to the gui. Used only for the src. vs. exec check.
 246         (gdbtk_init) added warning_hook
 247         added include <sys/stat.h>
 248

1347         (X11_LIBS): Define as -lX11.
1348
1349         * configure.in (enable_gdbtk): If gdbtk, support the --x-includes
1350         and --x-libraries switches, setting the X11_INCLUDES and
1351         X11_LIB_SWITCHES respectively.  Instead of using a hardcoded -lX11

1353
1354         * gdbtk.c (gdbtk_init): If SIOCSPGRP is not available, don't use

1378         * (breakpoint_notify):  Now returns just action and breakpoint
1379         number.
1380         * (gdb_get_breakpoint_list):  New routine.  Does the obvious.

1383         * (dsprintf_append_element):  Helper routine, works like printf,
1384         but appends a tcl element onto the specified DString.  Good for
1385         building up lists as return values.
1386         * (gdbtk_enable/disable_breakpoint):  Go away.  Replaced with
1387         gdbtk_modify_breakpoint.
1388         * (*many routines*):  Use new result protocol.
1389         * (call_wrapper):  Make sure that recursive calls don't trash results.
1390         * gdbtk.tcl:  New windows, autocmd, and breakpoints.
1391         * (gdbtk_tcl_fputs):  Don't use $current_output_win redirection
1392         anymore.  It's not needed (in fact, this routine may not be needed
1393         anymore).
1394         * (gdbtk_tcl_breakpoint):  Change to reflect new breakpoint
1395         notification protocol.
1396         * (gdbtk_tcl_busy gdbtk_tcl_idle):  Straighten out buttons, remove
1397         catches.
1398         * (interactive_cmd):  Use this wrapper around button invocations
1399         of many commands.  This will catch errors and put the results into
1400         the command window.  It also updates all the other windows.
1401         * Also, change reliefs of most things to sunken.  This actually
1402         looks better.
1403         * (create_file_win):  Fix margin binding to allow breakpoints to
1404         work again.
1405         * (create_asm_win):  Use return value of gdb_disassemble instead
1406         of implicit I/O to the command window.
1407         * (create_command_window):  Use new result protocol to get output
1408         from commands.

1411
1412         * gdbtk.c (gdb_disassemble): Deference pointer to function before
1413         calling it (pre-ANSI compilers generally require this).
1414

1416
1417         * gdbtk.c (gdb_disassemble): Get rid of
1418         dis_asm_read_memory_hook.  We can now call the disassemblers
1419         directly and have no need for this hook anymore.

1429         found.
1430         * gdbtk.tcl:  Initialize expr_update_list() to prevent errors when

1436         widget bug to make Options|Natural button work.
1437
1438         * gdbtk.c (gdb_disassemble):  Fix problem with source+assembly and
1439         g++ caused by out-of-order pc's.
1440         * gdbtk.tcl (files_command):  Remove duplicate file names.  Also,
1441         add scrollbar.
1442
1443 Mon Jan 23 17:21:09 1995  Stu Grossman  (grossman@cygnus.com)

1450         * gdbtk.c, gdbtk.tcl:  Update/add copyright.
1451         * gdbtk.tcl (build_framework):  Several fixes for filespec widget,

1464         Make copyright message have raised relief.
1465
1466         * gdbtk.c (gdbtk_init):  Improve handling for errors in gdbtk.tcl
1467         during startup.

1469 Thu Jan  5 17:38:29 1995  Stu Grossman  (grossman@cygnus.com)
1470
1471         * gdbtk.c (finish_saving_output):  Don't do anything if not saving
1472         output.
1473         * (breakpoint_notify):  Don't send null filename to tcl.
1474         * (gdb_eval):  New tcl command to eval an expression.
1475         * (gdb_disassemble):  New tcl command to do disassembly.  This
1476         allows tcl code to choose between exec file and target memeory,
1477         and can also do mixed source and assembly.
1478         * (gdbtk_init):  Move reading of gdbtk.tcl to the end to make sure
1479         that more of the environment is set up.  Also, create link between

1481
1482         * gdbtk.tcl:  New expression window support.
1483         * Make assembly window be 80 columns wide.

1496         windows to standard windows menu.
1497         (not_implemented_yet): Clarify message.
1498
1499 Fri Dec 30 15:49:00 1994  Stan Shebs  <shebs@andros.cygnus.com>
1500

1504
1505 Fri Dec 23 16:18:50 1994  Stu Grossman  (grossman@cygnus.com)
1506
1507         * gdbtk.c (gdbtk_wait gdbtk_init):  Portability improvements for
1508         SIGIO handling.

1513         is visible when creating new assembly windows.
1514
1515 Sun Dec 18 23:31:20 1994  Stu Grossman  (grossman@cygnus.com)
1516
1517         * gdbtk.c (gdbtk_wait gdbtk_init):  Use different method of
1518         enabling I/O interrupts for SVR4 (streams).
1519         * (start_saving_output save_output get_saved_output
1520         finish_saving_output flush_holdbuf gdbtk_flush gdbtk_fputs
1521         gdbtk_init):
1522         Totally revamp to use TCLs dynamic string functions.  Also, quote
1523         all data passed back to TCL to prevent errors with unmatched
1524         braces, odd characters, etc...  This fixes several wierd problems
1525         with outputting strings containing unmatched braces.
1526         * (breakpoint_notify gdb_loc):  Use long hex format to output
1527         addresses of breakpoints and PCs.  This fixes some Alpha problems.
1528         * (breakpoint_notify):  Add stream arg to call to gdbtk_fputs.
1529         * (gdb_listfiles):  Also, go through the symtabs when looking for
1530         files.  This makes xcoff work (sort of), but probably breaks
1531         something else.
1532         * (gdb_stop):  Return TCL_OK instead of nothing.  This fixes odd
1533         TCL errors when hitting stop button.
1534         * (tk_command):  Don't pass interp->result on to Tcl_{Var}Eval, as
1535         that will trash the result.  strdup the result instead and pass
1536         that on.  Improve error handling as well.
1537
1538         * gdbtk.tcl (gdbtk_tcl_flush):  Use global def of
1539         current_output_win.  Makes flushing actually work!
1540         * (asm_win_name create_asm_win update_assembly):  Bunch of fixes
1541         to make assembly windows stop flashing when loading a new file.
1542         * (gdbtk_tcl_busy gdbtk_tcl_idle):  Use catch to prevent gdb_cmd
1543         errors from losing control.
1544         * (create_source_window):  Add source file selection to View menu.
1545         * (create_command_window (<Key-Return> binding):  Quote text fed
1546         into gdb_cmd to prevent eval errors.

1549
1550         * gdbtk.c: Improve mechanism for capturing output values.
1551         (full_filename): Remove.
1552         (gdb_cmd call_wrapper gdbtk_init): Protect all calls from tcl land
1553         with call_wrapper.  This prevents longjmps (usually via error())
1554         from jumping out of tcl/tk and leaving things in an indeterminate
1555         state.
1556         (gdbtk_fputs): Differentiate stdout from stderr when passing text
1557         into tcl land.
1558         * gdbtk.tcl: New view option to disable line numbers.  Put catch
1559         around most uses of gdb_cmd.  Add update button to reg config
1560         window.  Stop doing immediate updates when selecting registers.
1561         Change register view values into checkbuttons.

1563 Mon Dec 12 16:59:29 1994  Stu Grossman  (grossman@cygnus.com)
1564
1565         * gdbtk.tcl (reg_config_menu create_registers_window
1566         recompute_reg_display_list):  Use array instead of individual vars
1567         for register display list.
1568         * (recompute_reg_display_list update_registers):  Fix bug with not
1569         displaying all registers.
1570
1571 Mon Dec 12 12:22:21 1994  Stu Grossman  (grossman@cygnus.com)
1572
1573         * gdbtk.c:  New tcl commands:  gdb_fetch_registers,
1574         gdb_changed_register_list, and gdb_regnames.
1575         * gdbtk.tcl:  Use monochrome color model for now.
1576         * (delete_breakpoint_tag create_file_win):  Add breakdot support.
1577         * (create_file_win create_asm_win update_listing build_framework
1578         create_source_window create_command_window):  Re-org window
1579         creation to give all windows consistent look and feel.
1580         * (update_listing update_asm):  Change pc pointer to '->'.
1581         * (registers_command reg_config_menu create_registers_window
1582         populate_reg_window update_registers):  Revamp register window.
1583         Allow selection of registers to be displayed.  Highlight changed
1584         registers.

1610 Tue Nov  1 16:41:12 1994  Stu Grossman  (grossman@cygnus.com)
1611
1612         * Makefile.in:  Use $(objdir)/tcl and $(objdir)/tk if they are
1613         available.
1614         * configure.in (ENABLE_CLIBS):  Use $(TCL) and $(TK) instead of
1615         -ltcl and -ltk.
1616         * gdbtk.c:  Get rid of lots of unnecessary #includes.
1617         * (gdbtk_init):  Use ConnectionNumber macro instead of referencing

1631         waits.
1632         * (gdbtk_call_command):  Wrapper around command processing to
1633         alert GUI of target state changes.
1634         * (gdbtk_init):  Get the fd of X server for doing async
1635         notification of X events (via x_event).  Setup new hooks.
1636         * gdbtk.tcl:  Add scrollbars to assembly and command windows.
1637         * Change window foreground & background colors.
1638         * Create margin tag for breakpoints in source and assembly windows.

1643         to just set or clear breakpoints when in the margin tag.
1644         * Change shape of register window to be more vertical to better
1645         reflect its contents.
1646         * Add stop button.
1647         * Cleanup some code around command window bindings.

1658         * (create_file_win):  Use catch to handle open failures more
1659         elegantly.  Also, create special window to display file open
1660         failure message.  Move opening of file prior to creation of text
1661         widget.
1662         * (create_asm_win):  Add PC as argument.  We now base disassembly
1663         on PC instead of function name, since function names can be
1664         ambiguous (usually seen with shared libs).  Also, use catch to
1665         simplify code where we don't care about failures.
