- Old DDD News (up to 2.2.3) -*- text -*-
- **************************
-
- DDD 2.2.3
- =========
-
- DDD 2.2.3 fixes some problems reported for DDD 2.2.2:
- - `struct' recognition with DBX now works again. (This one was serious.)
- - `configure' now checks for correct ISO C++ <stdexcept>.
- - DDD now runs under the `tvtwm' virtual desktop.
- - DBX Settings now work with Solaris DBX.
-
-
- DDD 2.2.2
- =========
-
- DDD 2.2.2 brings improved FORTRAN support, improvements in the
- data display and fixes some minor bugs introduced in DDD 2.2.
-
- User-visible changes to DDD 2.2.1:
- - Improved FORTRAN support. When debugging FORTRAN programs with
- GDB, DDD now supports FORTRAN array indexing syntax, FORTRAN
- pointer recognition, and lookup of FORTRAN functions with
- trailing underscore `_'.
- - The data display is now scope-sensitive: displays are
- automatically hidden as they become inactive (out of scope) and
- redisplayed as they become active again. This is handy when
- maintaining a multitude of displays in different scopes. For
- details, see the `hideInactiveDisplays' resource.
- - Faster data exploration. Double-clicking...
- * ...on a pointer value: dereferences it.
- * ...on a partially hidden value: shows more detail.
- * ...on a fully shown value: hides it again.
- - A display resize (due to value changes) now automatically
- `bumps' adjacent displays such that they are not obscured;
- see the `bumpDisplays' resource for details.
- - Case-insensitive search in the source text is now supported;
- see the `findCaseSensitive' resource for details.
-
- Bug fixes:
- - Getting and identifying core dumps now works on Solaris, AIX and
- other architectures.
- - `Edit' no longer causes DDD to crash.
- - The separate execution TTY now works with Sun DBX 4.0.
- - Improved XDB support. XDB output no longer causes DDD to hang.
- - Improved SGI DBX support. File positions are now recognized;
- DBX Settings work, too.
- - Various quirks and memory leaks in the interaction between DDD
- and the inferior debugger have been fixed.
-
- Changes in debugging DDD:
- - The interaction between DDD and the inferior debugger is now
- logged in `~/.ddd/log'. This is useful for bug reports.
- - DDD dumps core upon fatal errors (but resumes execution).
- This is useful for bug reports.
-
- Changes in configuration and building:
- - GCC 2.8.0 is supported.
-
- There are also some more minor improvements and bug fixes; see the
- `ChangeLog' file for details.
-
-
-
- DDD 2.2.1
- =========
-
- DDD 2.2.1 fixes some minor bugs introduced in DDD 2.2.
-
- User-visible changes to DDD 2.2:
- - When saving a session, you can now select the method for getting
- core files. This is useful on Solaris and SunOS systems.
-
- Bug fixes:
- - Auto-raised menus have caused problems on some architectures:
- they are now disabled by default. Use `Ddd*autoRaiseMenu: true'
- in `~/.ddd/init' to re-enable them.
- - By default, DDD stops disassembling after 1024 bytes. This is
- useful when working with the machine code of huge functions.
- See the `maxDisassemble' resource for more info.
- - Several status and diagnostic messages have been reworked; they
- now show the outcome of a command.
- - DDD now works around a bug present in Linux libc 5.4.38 to
- 5.4.40 that prevented DDD <-> GDB communication.
- - The `gcore' method for getting core files is now fully supported.
- - Various glitches in command queue management have been fixed:
- * Interacting with the debuggee (or interrupting it) now
- properly discards pending debugger commands.
- * In `--tty' mode, DDD can now handle long command sequences.
- This is useful when running DDD from Emacs.
- * In `--tty' mode, you can now send EOF (^D) characters to the
- debugged program without having DDD terminate GDB.
- - Trying to open non-existent source files no longer confuses GDB.
- - When running in the background, DDD is no longer interrupted by
- `tty output' signals upon initializing the execution window.
- - PushButton menus work with LessTif >= 0.82 and with OSF/Motif 1.1.
- - Command tool decoration has been improved and should now work
- with all X window managers.
-
- Changes in configuration and building:
- - GNU libiberty and the GNU configure scripts are now up-to-date.
- - The EGCS C++ compiler is supported (see `http://www.cygnus.com/egcs/').
-
- There are also some more minor improvements and bug fixes. See
- the `ChangeLog' file for details.
-
-
-
- DDD 2.2
- =======
-
- DDD 2.2 brings persistent sessions, an improved user interface,
- attaching to running processes, display shortcuts, and more.
-
- User-visible changes to DDD 2.1:
- - Persistent sessions.
- * You can now save the entire debugger and process state and
- resume the session later.
- * Saved state includes process memory and state, inferior
- debugger settings, breakpoints, and data displays.
- * X11R6 sessions are supported, too. When used with a
- session manager, DDD saves and restores its entire state.
- * Persistent sessions work best with GDB; DBX and XDB are
- partially supported, too.
- - Improved user interface.
- * DDD now requires less width and height.
- * Source line numbers have been turned off (can be restored);
- the breakpoint area extends to the first non-blank character.
- * The `Disable ()' button for disabling displays has gone;
- displays are now enabled or disabled via `Show ()/Hide ()'.
- * The `Break at ()' and `Clear at ()' buttons have been merged
- into one single dynamic button.
- * The `Windows' menu is now called `View', complying with the
- Motif style guide.
- * Options are now grouped according to their functionality. The
- `Options' menu has gone. Use `Edit' instead.
- * The `Edit' menu has been completely rewritten, allowing for
- better clipboard operations. For instance, you can now copy
- selected displays to the clipboard and paste them later.
- * Several buttons provide new pulldown menus with useful functions.
- - Improved command tool.
- * The command tool is always auto-raised, i.e. placed on top of
- the DDD windows.
- * The command tool always comes with window manager decorations,
- such that you can easily move it around.
- * The command tool sticks to the DDD source window: if you move
- the DDD source window around, the command tool follows.
- - Display shortcuts. Once you have changed `p' to `(char *) p'
- manually, DDD provides a menu shortcut for converting arbitrary
- values to `(char *)'.
- - Button editor. User-defined buttons can now be defined,
- changed, and deleted at run-time.
- - Support for debugging processes running outside of DDD. You can
- attach to a running process, examine it, and resume execution.
- - Helper customization. You can now interactively select and
- customize the applications to be used for the execution window,
- for editing source code, for browsing the DDD WWW page, etc.
- - Improved online manuals.
- * Multiple manual browsers are supported.
- * Manual browsers are realized as top-level windows.
- * DDD no longer blocks while the manual is uncompressed and formatted.
- * DDD stores manuals in `gzip' format, saving space in executables.
- - New `What Now?' help. Gives a hint on what you can do next,
- depending on the current DDD state. Useful for beginners.
- - Improved data display.
- * Displayed data is highlighted whenever it changes.
- * Two-dimensional arrays are now laid out as tables.
- * Numerical values are now aligned to the right.
- * You can now incrementally `Show More' details of an object,
- instead of showing all details at once.
- * Processing displays can be interrupted by typing Ctrl+C.
- - Drag and drop support.
- * You can now alter the current execution position interactively
- by dragging and dropping the execution arrow. This allows you
- to back up - perhaps with more breakpoints set-over a portion
- of a program that has already executed, in order to examine
- its execution in more detail.
- * Breakpoints can be dragged and dropped, too. This allows you
- to move breakpoints to alternate positions, without changing
- their properties.
- - Improved display of breakpoints and execution positions.
- * The current execution position is now properly cleared if
- undetermined (no source, program terminated, etc.)
- * If the program stopped due to a signal, this is indicated
- by a lightning symbol within the current execution glyph.
- * Faster scrolling. While scrolling source or machine code at
- high speed, glyphs are now unmapped. Slow scrolling still
- shows glyphs.
- - Improved DBX and XDB support.
- * DDD supports DBX and XDB breakpoint conditions.
- * With SUN DBX 3.x, DDD also supports disabled breakpoints
- and ignore counts.
- - User-defined DDD commands. DDD now provides a simple facility
- that allows the inferior debugger to execute DDD commands. For
- details, see `User-Defined Commands' in the DDD manual.
- - For `Continue Until Here', DDD now sets a temporary breakpoint
- and continues (instead of using the GDB `until' command). If
- the temporary breakpoint is not reached, it is deleted.
- - When restarting DDD, all settings (data displays, execution
- position, etc.) are preserved.
- - When DDD becomes ready after a user command, it automatically
- uniconifies itself. Hence, you can iconify DDD while it runs a
- program; DDD pops up again as soon as a breakpoint is hit.
- - Characters typed into the data and source windows are now
- forwarded to the debugger console.
- - Resource files have been renamed. All files are now located
- under `~/.ddd/'. The file `~/.dddinit' has been replaced by
- `~/.ddd/init'; `~/.ddd_history' is now `~/.ddd/history'. The
- new directory `~/.ddd/sessions/' contains saved DDD sessions.
- - Your window manager should now show multi-color DDD icons.
- (requires XPM; can be disabled)
- - During start-up, DDD shows a multi-color logo in a transient
- window. (requires XPM; can be disabled)
- - DDD now typically requires 35% less memory. This was achieved
- by compiling and optimizing DDD regular expressions at compile
- time, rather than generating them at run time.
-
- Supported platforms and configurations:
- - Support for Linux with GNU libc 5.4.38 and later included.
- - Support for XDB on HP-UX 10.x included. Thanks to Robert
- Wiegand <wiegand@kong.gsfc.nasa.gov>.
- - Support for SUN DBX 3.2 included.
-
- Bug fixes:
- - DDD no longer hangs while receiving large chunks of data.
- - DDD now also works with echoing TTY connections.
- - Significant speed-ups in processing debugger and program output.
- - Several memory leaks and X resource leaks have been tightened.
- - DDD no longer requires the librx library. Consequently, librx
- errors can no more cause DDD to crash.
- - A serious bug that caused timers to be inadvertently removed has
- been fixed. Bug effects included loss of console cursor, loss
- of data display contents, and loss of scrolling capabilities.
- - DDD now handles GDB `<repeats N times>' output correctly.
- - And again, hundreds of minor improvements and bug fixes. See
- the ChangeLog for details.
-
-
- DDD 2.1.1
- ---------
-
- DDD 2.1.1 includes some hacks that make DDD run with LessTif, a
- free Motif clone, without loss of functionality. DDD now no more
- depends on proprietary software like OSF/Motif.
-
- Apart from these hacks, functionality is unchanged with respect to
- DDD 2.1 (no new features, no bug fixes). If you have DDD 2.1 up
- and running, there is no need to upgrade to DDD 2.1.1.
-
- As of this release, DDD is included in GNU CD-ROMs by the Free
- Software Foundation (aka the GNU people). DDD distributions are
- now numbered according to the GNU Maintenance Instructions.
-
-
-
- DDD 2.1
- -------
-
- DDD 2.1 brings alias detection, local variable displays, button
- and value tips as well as several new features and bug fixes.
-
- User-visible changes to DDD 2.0:
- - Alias detection. DDD now recognizes that multiple displays
- reference the same object. This allows the examination of
- shared data structures (circular lists, DAGs, and so on). Alias
- detection slows down DDD a bit, so it is turned off by default.
- - Local variable displays. You can display all local variables
- and arguments in the data display. The display is automatically
- updated to reflect the list of variables and their values.
- - Status displays. You can now view the output of a debugger
- command in the data window, using "graph display `COMMAND`".
- For instance, local variable displays are realized via
- "graph display `info locals`".
- - Button tips. Moving the mouse pointer over a button causes a
- small hint window (aka `balloon help') to raise. (optional)
- - Value tips. Moving the mouse pointer over a variable causes a
- small window to raise showing the current value. (optional)
- - The status line has been reworked and extended:
- * It displays information about the selected item.
- * It has moved to the bottom, such that menu entries can be
- described. (can be restored)
- * It contains a debugger status indicator, blinking whenever
- the inferior debugger is busy. (can be turned off)
- * You can re-display the most recent messages.
- - The register window can display floating-point registers.
- - Thread support. You can inquire existing threads and switch
- among them. (requires GDB and operating system thread support)
- - In `one single window' mode (now default), you can disable
- specific window parts (e.g. data displays, debugger console,
- etc.) through the `Windows' menu.
- - The `Preferences' panel has been extended and reworked:
- * Button tips and value tips can be enabled and disabled.
- * Tab width and graph grid size can now be changed at run time.
- * You can choose at run time whether command buttons should
- be placed in the command tool (as in DDD 2.0) or in the
- source window (as in DDD 1.x).
- * You can reset the DDD preferences to the least recently saved
- settings.
- - Some items have been renamed for clarity:
- * The `Stack' menu is now named `Status', as it hosts other
- status-related items besides backtrace and registers.
- * The `Break' button is now named `Interrupt' (as in DDD 1.x),
- to avoid confusion with the `Break At' button.
- * The `Quit' menu item is now named `Abort', to avoid confusion
- with the `Exit' menu item (which issues a `quit' command).
- - Some key bindings have been re-assigned. Generally, `Ctrl'
- invokes debugger or editing commands, and `Alt' changes debugger
- settings. Hence, Ctrl+M invokes `make' and Ctrl+Q invokes
- `quit', while Alt+M enables or disables the machine code window.
- `Run' is now on Ctrl+X (for eXecute).
- - DBX settings can now be viewed and changed at run time, using
- the `Settings' panel.
- - In GDB, there is a `status displays' panel for displaying
- various things about the program being debugged.
- - Reading the VSL library is now realized as a background job,
- reducing startup time drastically.
- - In the data window, the middle mouse button now toggles
- the display selection instead of simply extending it.
- - The most important data window operations can now also be
- invoked via the debugger console. For instance, the command
- `graph display *next at (50, 50) dependent on 1' creates a new
- dependent display at (50, 50). In the long term, this feature
- will be used to save and restore display state.
- - In the debugger console, the right mouse button invokes a small
- popup menu which you can use to clear the line or the window.
- - Ever suffered from a frozen display while debugging a modal
- application? If the debugged program is interrupted in some
- modal state, DDD will automatically make it ungrab the pointer.
- - You can now clear all argument fields `()' by clicking on the
- prompt `():'.
- - In the source argument field `()', pressing RETURN activates
- the `Lookup ()' button.
- - `Save Options' saves window sizes for later DDD sessions, as
- well as the relative position of the command tool.
- - Unnecessary redisplays have been significantly reduced, causing
- much less flickering.
- - If you specify some overloaded or ambiguous identifier, DDD now
- lets you select from all alternatives.
- - Buttons not supported on certain debuggers (for instance,
- `Finish' on DBX) are now made insensitive. (optional)
- - You can now invoke `make' from DDD, reusing old `make' arguments
- from the command history if desired.
- - There is a new integrated manual browser showing manual pages
- and info files for DDD as well as for the inferior debugger.
- A simple search facility is also included.
-
- Documentation:
- - The PostScript copy of the manual has been enriched with more
- than 30 color screen shots showing DDD usage.
- - A `sample.dddinit' file is included in the distribution
- containing several examples for further customization.
-
- Changes in configuration and building:
- - DDD 2.1 uses improved configuration checks from Autoconf 2.12.
- - DDD no longer installs in the `gcc' location by default, but in
- an existing DDD location; otherwise, in `/usr/local/bin'.
- - Improved means of determining builder's e-mail address.
- - DDD beta releases and DDD snapshots expire after a few weeks.
-
- Bug fixes:
- - Using DBX, comments were stripped from source code under certain
- circumstances. Fixed.
- - The sash to resize the assembler window is back again.
- - With XDB, sources are found in alternate directories, too.
- - With DBX, the current source line was omitted from the listing
- under certain circumstances. Fixed.
- - With Sun DBX, DDD uses the DBX display numbers instead of
- generating own numbers.
- - `Help on Version' no longer includes the entire DDD
- configuration.
- - Several single-letter options like `-d DIR' are now properly
- passed down to the inferior debugger.
- - `Select All' followed by `Delete' no more causes DDD to crash.
- - Problems with button specs ending in `...' have been fixed.
- - Line continuations (i.e. lines ending in `\') are properly handled.
- - Problems in building the `vsl' and `test-graph' programs are fixed.
- - On Linux, drag-and-drop of pixmaps has been disabled explicitly.
- (Several Linux Motif configurations are broken in this aspect.)
- - DDD now sets the WM_COMMAND resource such that X session
- managers can save and restore DDD state.
- - The data window now uses a command queue for operations on data
- displays. No more `The debugger is busy' messages.
- - Improved handling of template-generated class names and
- optimized-out structs.
- - And again, dozens of minor bug fixes and improvements.
-
- Release policy:
- - Due to the large amount of testing, we make new DDD releases
- only every six months or so. If you found a bug and fixed it
- for us or just reported it to us so we could fix it, then this
- release scheme may not be good enough for you. Therefore, we
- now also have a daily snapshot of our CVS repository. See the
- DDD WWW page `http://www.cs.tu-bs.de/softech/ddd/' for details.
-
-
-
- DDD 2.0
- -------
-
- DDD 2.0 brings XDB support, extended DBX support, an improved user
- interface as well as several new features and bug fixes.
-
- User-visible changes to DDD 1.4:
- - New command tool. All command buttons that do not take
- arguments are now located in the command tool, a small separate
- window. The command tool can be moved wherever appropriate,
- leaving more space for window contents.
- - User-defined buttons are now available. These can also
- be used to re-install the old command buttons.
- - Colored displays. You can specify individual colors for
- pointers, arrays, structs, and so on.
- - Variable values can now be altered interactively during program
- execution.
- - You can inquire the types of variables and functions (`whatis')
- through the source popup menu.
- - Selecting a data display item now also sets the `()' argument field
- in the source window, making it available for further commands.
- - `New display' subsumes `Dependent display': if a display is
- selected, the new display is made dependent on it.
- - `Show Detail' expands the entire selected value, including all
- contained sub-structures.
- - Option editors. New panels for DDD preferences and GDB
- settings. GDB settings can be saved across DDD sessions.
- - Some items have been renamed for further clarity:
- * The `command window' is now named `debugger console', to avoid
- confusion with the command tool.
- * The `Interrupt' button is now named `Break', to associate the
- concept with `Breakpoints'.
- * The `Break ()' and `Clear ()' buttons are now named `Break at ()'
- and `Clear at ()', respectively.
- * The `Dereference' button is now named `Display *'.
- - DDD now supports GDB-like incremental search in the command history.
- It is invoked through Ctrl+R and Ctrl+S in the debugger console.
- - Incremental search required some changes in keyboard shortcuts.
- `Run' is now Ctrl+Z, `Step' is Ctrl+I, and `Next' is Ctrl+J.
- - The `Save Options on Exit' function has been removed, as it
- also saved options given upon DDD invocation like `--dbx' or
- `--exec-window'. Options must now always be saved explicitly.
- - You can press Ctrl+\ to interrupt programs using a QUIT signal.
- - Ctrl+C and Ctrl+\ now have the highest priority of all events.
- - Improved remote debugging. In contrast to `--host', the new
- `--rhost' option uses `rsh' without arguments (aka `rlogin')
- to access the remote debugger. DEC and SGI DBX require this.
- - The DDD License can now be viewed from within DDD.
- - DDD resources and actions are now fully documented; the DDD manual
- contains several customization examples (fonts, colors, buttons).
-
- Supported debuggers and languages:
- - XDB support. On popular request, DDD now also supports HP's XDB as
- inferior debugger.
- - Extended DBX support. DDD determines DBX properties
- at run-time and adapts automatically to a wide range of DBX
- variants.
- - Even more DBX support. DDD now supports DBX on SUN, DEC, AIX,
- and IRIX systems.
- - Language support. DDD uses Pascal-style dereferencing (X^
- instead of *X) if the current frame was written in Pascal, Ada,
- or Modula. (GDB only)
- - Modula-3 support. DDD supports `m3gdb', a GDB extension for Modula-3.
- Thanks to Peter Klein <pk@i3.informatik.rwth-aachen.de>.
-
- Changes in configuration and building:
- - New top-level `configure' script. DDD now uses an `autoconf'-
- generated top-level `configure' script instead of Cygnus
- `configure'. Among other advantages, configuration options are
- now properly passed down to subdirectory configuration.
- - Regular expressions now use the POSIX.2 standard regcomp/regexec
- interface. The slower interface is compensated by smarter calls.
- - DDD configuration now generally attempts to link with native system
- libraries wherever possible. GNU termcap and librx are used
- only if the system does not provide them. This results in
- smaller and (hopefully) safer DDD executables.
- - DDD configuration tests whether your C++ compiler can compile a
- `hello, world' program. It is amazing how many misconfigured
- C++ compilers exist in the world.
- - You can specify `--without-athena' to avoid searching for and
- linking with Athena libraries.
- - Patches for AIX xlC, Sun CC, GCC 2.8.0 and probably other
- C++ compilers included. Thanks to Jacek Holeczek
- <holeczek@clri6f.gsi.de> and Jason Merrill <jason@cygnus.com>.
- - DDD now compiles and runs unchanged with LessTif, a free Motif
- clone under construction. Note that `runs' is relative: As of
- LessTif 0.50, DDD is still far from being usable. This will
- change as LessTif evolves.
-
- Bug fixes:
- - Improved directory support. Sources and executables can reside
- in several different directories. With DBX and XDB, DDD
- optionally uses full file paths when referring to source positions.
- - Several TTY problems fixed. Switching between execution window
- and debugger console should work fine now; the execution window
- can be opened, closed and re-opened without DDD crashing or
- hanging.
- - The terminal type (TERM environment variable) of the debugger
- console and the execution window is now properly set.
- - Editor problems fixed. Invoking a source editor via `Edit'
- should work fine now.
- - The rubber band outline no more clutters the data display.
- (This was a GCC optimization bug.)
- - No more endless scrolling when glyphs are enabled. Scrolling is
- slightly faster, too.
- - On HP-UX, the `@' character is no more discarded from GDB input.
- - On Solaris 2.x, annoying DBX warnings like `dbx: -r option only
- recognized for C++' are silently ignored.
- - You can now specify the location of own VSL libraries via the
- `vslPath' resource.
- - Improved diagnostics (file names and line numbers) for VSL errors.
- - The `--attach' and `--separate' options are no more overridden
- by the settings in `~/.dddinit'.
- - The `-synchronous' option (for X debugging) now works;
- `--synchronous-debugger' has been renamed to `--sync-debugger'.
- - The source window no more scrolls back to some previous position
- when adding or removing breakpoints.
- - Pagers (`more', `less', etc.) invoked by the inferior debugger
- are properly handled. (When seeing `--More--', DDD hits the
- space key.)
- - And, of course, hundreds of minor bug fixes and improvements.
-
- Release policy:
- - Before every new feature release (like this one), we shall make
- beta releases publicly available. They are named like the major
- release, but have `beta' and a number appended. For instance,
- this release was preceded by `ddd-2.0beta1', `ddd-2.0beta2', and
- so on. Beta releases will be announced in DDD mailing lists
- only.
-
-
- DDD 1.4d
- --------
-
- Bug fix release; fixes problems introduced in DDD 1.4c.
-
- Changes to DDD 1.4c:
- - Several people have reported problems accessing the fonts
- specified in DDD 1.4c. We have thus now re-enabled the scheme
- from DDD 1.4b; how to change fonts is explained in the DDD FAQ.
- - Various fixes for C++ compilers other than GCC included (notably
- Sun CC 4.0 on Solaris 2.x)
- - The VSL interpreter can now be controlled upon DDD invocation;
- type `ddd --vsl-help' for a list of options. This is intended
- for debugging forthcoming display customization.
-
- This release should configure, compile and run out-of-the-box on
- OSF systems. Please let us know about any remaining problems.
-
-
- DDD 1.4c
- --------
-
- Bug fix release. No user-visible changes.
-
- Changes to DDD 1.4b:
- - Major restructuring of `ddd.C', the DDD main program;
- compilation should now require slightly more time, but much less
- memory. Due to the large number of new files, diffs to earlier
- versions are somewhat larger than usual.
- - Font sizes are now resolution-independent, resulting in larger
- font sizes on high-resolution displays.
- - The built-in manual page is now compressed, resulting in
- slightly smaller executables.
- - Improved DBX 3.x support. Thanks to Grant McDorman
- <grant@isgtec.com>.
- - Improved DEC Alpha/OSF support. Thanks to Phil Brooks
- <phil_brooks@MENTORG.COM>.
- - Several minor and two major bugs were found and fixed.
-
-
- DDD 1.4b
- --------
-
- Bug fix release.
-
- Changes to DDD 1.4a:
- - Much faster start-up, due to delayed parsing of the VSL library.
- - Custom paper size support for printing graphs.
- - Paper size and printing command is saved with options.
- - On some X11 configurations, DDD was caught in a busy loop upon
- invocation. Now fixed.
- - On some Linux configurations, DDD crashed immediately upon
- invocation. Now fixed.
- - Manual update of data display (`graph refresh') improved.
- - `set' and `assign' commands automatically update the data
- display.
- - New releases of top-level `configure' and `libiberty' included.
- - Building DDD creates executable with canonical name.
-
-
- DDD 1.4a
- --------
-
- Bug fix release. No user-visible changes.
-
- - Compilation trouble with older GCC versions as well as
- older C++ compilers fixed.
- - Compilation in separate directory fixed.
- - For older GDB versions, one may use `display /x $pc' and `print
- /x $pc' to get the current PC value.
- - Minor bugs in construction and installation fixed.
-
-
- DDD 1.4
- -------
-
- DDD 1.4 realizes the top ten suggestions of DDD users. It brings
- the long awaited machine code support, new breakpoint and
- execution symbols, improved DBX support, enhanced integration
- facilities and many small features and improvements.
-
- Changes to DDD 1.3:
- - Full machine code support: Assembler and register windows,
- Breakpoints in machine code, no-source debugging, stepping over
- instructions. (GDB only)
- - Breakpoints and the current execution position are displayed as
- stop signs and arrow symbols (``glyphs'') instead of text. Our
- students find that cute; the old mode is still available.
- - New argument editor: Upon program start, select from a list of
- previously used program arguments.
- - Using the new `--tty' option, DDD can be easily integrated with
- other GDB/DBX front-ends. For instance, you can have DDD run as
- an inferior debugger from your Emacs GDB-mode, having all Emacs
- and DDD facilities at your disposition.
- - Improved C++ support with DBX 3.x. Thanks to Grant McDorman
- <grant@isgtec.com>.
- - Displays with format expressions (`/x') are properly dereferenced.
- - Improved position history mechanism.
- - Automatic reloading of source files when the debugged program
- has changed; explicit reload is no longer required.
- - File selection dialogs are synchronized: changing the directory
- in one dialog also changes the directory in all others.
- - Interactive dialogs for disambiguating C++ names.
- - Several major and minor bugs have been fixed. Special thanks to
- Grant McDorman <grant@isgtec.com>.
- - DDD incorporates the name of its builder in `Help/Show Version'.
- - No more `Help on Debugging' item. Sigh.
-
-
- DDD 1.3e
- --------
-
- Bug fix release.
-
- - Some compilation trouble with older GCC versions as well as
- older C++ compilers fixed; thanks to Albert Chin-A-Young
- <chinay@cig.mot.com>.
- - Some configuration trouble with non-GCC compilers and Motif 2.0
- fixed; thanks to Larry Schwimmer <rosebud@cyclone.stanford.edu>.
- GNU Autoconf 2.7 is now used.
- - Functionality is unchanged; executables are identical.
-
-
- DDD 1.3d
- --------
-
- Bug fix release.
-
- - Anonymous unions and bitfields are now processed correctly.
- - `Continue Until Here' (was `Set Temporary and Continue')
- now also stops if current stack frame is left (GDB only)
- - More patches for Linux ELF incorporated. Thanks to
- lee@tcs.com (Lee Hounshell) and jdassen@wi.leidenuniv.nl (J.H.M. Dassen)
- - Non-textual source files (binary characters, no newline at end)
- are now processed correctly.
- - Basic support for DEC's dbx included.
-
-
- DDD 1.3c
- --------
-
- Bug fix release.
-
- - Patches for GCC 2.7.1 incorporated.
- - Patches for recent Linux boxes (using ELF format) incorporated.
- Thanks to lee@champion.tcs.co.jp (Lee Hounshell).
- - Patches for DEC Alpha OSF/1 incorporated; see the `PROBLEMS'
- file for special building instructions. Thanks to
- tuppa@iue.tuwien.ac.at (Walter Tuppa)
- - Configuration scripts reworked for GNU autoconf 2.6; various
- configuration bugs have been fixed.
-
- - New shortcuts in source popup menus:
- * The breakpoint popup menu allows you to set a temporary
- breakpoint and continue immediately.
- Suggested by Chris Sterritt <sterritt@mrj.com>
- * The source popup menu allows you to print or display
- dereferenced names (`print *' and `display *'). Suggested by
- Walter Tuppa <tuppa@iue.tuwien.ac.at>
-
- - All DDD source code (except `ddd.C') now comes under the GNU
- general public *library* license. This means that the following
- is now allowed under certain circumstances:
- * Proprietary DDD extensions without supplying source code, and
- * Incorporating DDD code in proprietary applications
- See the `COPYING.LIB' file for details.
-
-
- DDD 1.3b
- --------
-
- Bug fix release.
-
- - More minor troubles with GCC 2.7.0 on certain architectures fixed.
- - DDD can now be interrupted using the SIGINT signal.
- - In the breakpoint editor, you can now set multiple breakpoint
- conditions and ignore counts at a time.
- - The DDD WWW page has moved to `http://www.cs.tu-bs.de/softech/ddd/'.
-
-
- DDD 1.3a
- --------
-
- Bug fix release.
-
- - Minor troubles with GCC 2.7.0 on certain architectures fixed.
- - New help item: DDD WWW Page.
-
-
- DDD 1.3
- -------
-
- This release compiles using GCC 2.7; some new features have been
- added and several minor bugs fixed. Some bugs remain; see the
- `BUGS' file for details.
-
- Changes to DDD 1.2:
- - You can now edit the current source via an external editor.
- - Display placement has been improved; new displays are now
- created in the current visible view, if possible.
- - The current execution position now stays near the middle of the
- visible source code. Following statements remain visible.
- - Diagnostics of printing commands no longer get lost.
- - Upon fatal errors, DDD tries to resume execution by returning to
- the main event loop. This leaves you a chance for exiting the
- debugged program properly.
- - New `Help on Debugging' item.
- Written by David A. Lyons <dlyons@apple.com>.
- - Colours slightly reworked: text background is a little brighter.
- - A short DDD survey, including lots of screen shots, is included
- in `doc/ddd-paper.ps'. The paper also highlights some internal
- aspects of DDD.
- - DDD source code has been adapted to the current ANSI/ISO C++
- draft standard. Any GCC release from 2.3.3 onwards, including
- the recent GCC 2.7.0, should now compile DDD (unjustified
- commpiler warnings in GCC 2.5 or lower, though).
- - DBX support on Solaris improved.
- Thanks to grant@isgtec.com (Grant McDorman)
- - Patches for FreeBSD incorporated.
- Thanks to smcarey@mailbox.syr.edu (Shawn M. Carey).
- - DDD-specific application defaults now override user application
- defaults. Thanks to ksfdo0@ksepl.shell.nl (Fred Donck).
- - New GNU librx 0.07.2 library included (from libg++-2.7.0),
- should be faster and more reliable.
-
- Thanks to all who sent in bug reports and suggestions. DDD now
- runs on every major UNIX flavour (with the exception of OSF/1 -
- any volunteers for that task?).
-
-
- DDD 1.2
- -------
-
- Again, a bug fix release. Many minor bugs have been fixed; see
- the `ChangeLog' file for details.
-
- Changes to DDD 1.1:
- - DDD source code should now be ANSI/ISO C++ conformant - all code
- specific to GCC or libg++ has been adapted. DDD now also
- compiles using other C++ compilers than GCC (Sun's CC 4.0 works
- fine; AT&T Cfront 3.0 has trouble with some inline functions).
- - DDD should now run correctly on SGI/IRIX machines.
- - Interrupting processes via the Interrupt button now works
- correctly on Solaris, HP-UX, and other systems.
- - Improved support for GDB artificial arrays.
- - The GDB command window has improved control character support.
- Tabs, Carriage returns, Backspaces and so on are processed
- correctly. Unprintable characters are also handled.
- - There is an option to suppress X warnings. This may be useful
- for people annoyed by tons of Motif Keysym warnings.
- - We have started to compile a FAQ list to reduce our daily mail
- load. See the file `FAQ' for details.
-
- Thanks to all who sent in bug reports and suggestions.
-
- As building DDD is still a major challenge for some users, we
- encourage everyone to share her/his binaries with others. See the
- file ftp.ips.cs.tu-bs.de:/pub/local/softech/ddd/bin/README for
- details.
-
-
- DDD 1.1
- -------
-
- Never trust a ``dot-oh'' release - DDD 1.0 had a serious bug that
- caused DDD to crash upon various occasions, often after a few
- interactions.
-
- Under certain circumstances and on many architectures, the
- hourglass cursor routines could corrupt the stack at a random
- point and thus throw a time bomb into DDD, making DDD fail at
- unpredictable (and unrepeatable) places. This bug has been fixed;
- some other minor bugs were fixed, too. See the `ChangeLog' file
- for details.
-
- Changes to DDD 1.0:
- - C++ References and VTables are fully supported.
- - The source popup menu no longer changes the source selection.
-
-
- DDD 1.0a
- --------
-
- Bug fix release.
-
- On many architectures, this DDD release should be much more
- robust. For unknown reasons, DDD 1.0 choked soon after destroying
- some of its widgets - a bug that must have been introduced at the
- very end of the beta test phase and thus have gone by unnoticed.
- This bug, and some other minor bugs, have been fixed.
-
-
-
- DDD 1.0
- -------
-
- First public DDD release. Many thanks to all who spent their time
- in testing DDD, sending bug reports and suggestions, and making
- DDD what it is today.
-
- This DDD release should configure, compile and run out-of-the-box
- on the following systems:
-
- hppa1.1-hp-hpux9.05
- linux-i386-unknown
- linux-i486-unknown
- mips-dec-ultrix4
- powerpc-ibm-aix3
- rs6000-ibm-aix3
- sparc-sun-sunos4
- sparc-sun-solaris2
-
- If your system is in the list above, please let us know if you
- encountered any problems (unless these are known problems listed
- in the `BUGS' and `PROBLEMS' files). If your system is not in the
- list above, please let us share your experiences.
-
- Changes to DDD 0.9:
- - Several last-minute bugs have been fixed.
- - New `Program' menu, introduces keyboard accelerators for frequently
- used commands.
- - Graph printing reworked; you can now set paper size and graph
- orientation. The bounding box is computed correctly for all sizes.
- - The `Graph' menu has been dropped; its items have been moved
- into the `Data' and `File' menus.
- - Selecting and moving multiple displays made easier.
- - Pointers to functions are now displayed correctly.
- - Regex name conflicts on Linux fixed.
-
- Announce policy for future releases:
- - Bug fix releases shall be named 1.0a, 1.0b, and so on.
- In general, they will be announced in DDD mailing lists only.
- - Feature releases shall be numbered 1.1, 1.2, 1.3 and so on.
- They will be announced in USENET news as well.
