DDD 3.3.1
=========
DDD 3.3.1 brings a couple of minor bug fixes:
- The option to create new displays `left-to-right' is restored upon startup.
- Fortran struct members are accessed as `A%B' instead of `A.B'.
- Structure changes in plotted displays no longer crash DDD.
- You can specify the top-level geometry via `-geometry'.
- The `pydb' debugger has been fixed to work with recent Python releases.
- Ornamented Perl debugger prompts are handled correctly.
- DDD honors the TMPDIR environment variable for creating temporary files.
- `config.guess' and `config.sub' scripts have been updated.
- Minor compilation problems with GCC 2.7.2 have been fixed.
- Minor compilation problems with GCC 3.0 (prerelease) have been fixed.
- Minor compilation problems with Sun CC have been fixed.
- Minor potential problems with 64 bit pointers have been fixed.
DDD 3.3
=======
DDD 3.3 brings data themes, debugger interaction while the program is
running, support for JDB 1.2, and several bug fixes.
Data Themes
-----------
- DDD supports _data themes_ - modifiers that change the appearance of
program data. Try `Data->Themes'.
- Data themes included with this release are:
* Show specific expressions in a smaller font (useful for arrays).
* Show display titles in a smaller font.
* Suppress specific structure members or expressions.
- New data themes can be defined by users and installed at run-time.
- More themes are in preparation, such as rendering of C++ STL data structures.
Debuggers and Languages
-----------------------
- JDB as of JDK 1.2 is supported.
- GDB 5.0 is supported.
- You can use `ddd --wdb' to have DDD startup with WDB.
- When choosing a debugger automatically, DDD will try `wdb' if `gdb'
is not available.
- WindRiver's version of GDB (within the Tornado/vxworks environment)
is supported. See the DDD Reference, Section `WindRiver GDB' for
details. (5)
- SGI DBX, Sun DBX, other DBXes as well as Compaq Ladebug can now
attach to processes via DDD. (1)
- Parsing of GDB breakpoint information has been improved. (2)
- Parsing of Perl breakpoint information has been improved.
- Perl hash keys containing spaces are supported. (8)
- Using the separate execution window now improves parsing debugger
output. See the DDD documentation for the new `bufferGDBOutput'
resource.
Examining Data
--------------
- New displays can be created left-to-right.
See `Edit => Preferences => Data => Placement'. (6)
- Handling of Ladebug array output has been improved. (7)
- Handling of multiple C++ base classes has been improved.
- Names that are keywords in some programming languages (such as
`interface', `object', `class') should no longer impose problems when
occurring in programs of other languages.
- Several memory leaks have been plugged. (1)
User Interface
--------------
- The default DDD font has been changed from `helvetica-bold' to
`helvetica-medium', thus integrating better into KDE and GNOME
environments.
- You can interact with the debugger while the program is running;
DDD automatically interrupts and resumes debuggee execution. See the
`stopAndContinue' resource for details.
- Undo and Redo now apply on logical groups of commands. If an action
caused multiple commands, Undo will undo them with one click.
- Interrupts (Ctrl+C) from the controlling TTY can be issued multiple times.
- With LessTif, the source window no longer scrolls around when
setting or deleting breakpoints.
- With LessTif, combo boxes (drop-down text boxes) no longer shrink.
- With LessTif, Text selection works better.
- With LessTif, typing in the debugger console works better.
- With LessTif, switching the register set works.
- Drag and Drop of breakpoints in the machine code is supported.
- Names of debuggee files and directories may contain spaces.
- Spin boxes (used to step values) have been slightly improved.
- Forwarding of keyboard events from the source window into the
debugger console is now optional. See the `consoleHasFocus' resource. (10)
Printing
--------
- PostScript printing includes background colors (e.g. changed values)
Installation
------------
- PLEASE NOTE: Several installation details have changed. Be sure to
read the `INSTALL' file for new installation instructions.
- Several DDD resources (such as the application defaults) now reside
in separate files, reducing DDD executable size and memory footprint
by about 300k.
- To run DDD from the build directory (i.e. before installing), you
must set the DDD_HOME and XUSERFILESEARCH environment variables.
See the `INSTALL' file for details.
- The configure `--enable-rpath' option allows you to specify a path
to be searched for dynamic libraries at run-time.
- DDD Makefiles are now GNU standards-compliant and generated by automake.
- DDD Makefiles use libtool for generic shared library support.
- A bad dependency on $(SHELL) in the Makefile has been fixed. This
caused unnecessary calls of flex and bison in the distribution. (9)
- A bad wildcard use in the Makefile has been fixed. (3)
- A compilation problem in `PannedGE.C' with some GCC variants has been fixed.
- DDD now compiles cleanly even with `gcc -Wwrite-strings'. This
avoids several warnings/errors on C++ compilers other than GCC. (1)
- The `--configuration' option now gives more information about the
compiler being used to compile DDD. (1)
- ddd.texi rules in the Makefile have been fixed. (4)
- The release includes the `libiberty' and `readline' packages as of GDB 5.0.
License
-------
- All remaining parts of DDD that used the GNU Library Public General
License (LGPL) have been changed to use the GNU General Public
License (GPL) instead.
- The DDD Manual is released under the new GNU Free Documentation License.
Tracking Code Changes
---------------------
- This release no longer includes `ChangeLog' files. Instead, you can
directly access old and recent DDD versions (including a list of all
changes) via the public CVS interface at
http://sourceforge.net/projects/ddd/
- You can also download most recent DDD versions from the public CVS
interface. See the file `README-CVS' in the CVS archive for details.

- [LessTif] Restarting DDD (while saving settings) works fine.
- [LessTif] Small fixes for building with LessTif on SGI.
- [Perl] In the data display, Perl hash keys are properly quoted.
- [Ladebug] More Ladebug variants are supported.
- [Ladebug] `Edit -> Ladebug settings' should work.
- A string pointer error on 64 bit machines has been fixed.
- Minor bugs with clustered displays have been fixed.
- DDD makes more attempts in locating the initial main function.
- DDD PostScript documentation can be printed on multiple pages per sheet.
DDD 3.2
=======
DDD 3.2 brings a new documentation and several minor improvements.
DDD is now a GNU program
------------------------
- Starting with this release, DDD is an official GNU program,
distributed by the Free Software Foundation. This brings a number of
administrative changes:
* DDD is distributed as source only using GNU FTP sites and mirrors.
* The DDD WWW page is now `http://www.gnu.org/software/ddd/'.
* The DDD mailing addresses are now `bug-ddd@gnu.org' (for bug reports)
and `ddd@gnu.org' (for announcements, discussions, or anything else).
You can subscribe to these lists by sending an e-mail to
`bug-ddd-request@gnu.org' and `ddd-request@gnu.org', respectively.
The old mailing list addresses are now just aliases for the new ones.
Documentation
-------------
- There is a new DDD manual, generated from Texinfo source, and coming
in HTML, PDF, PostScript, Info, as well as plain text format.
Debuggers and Languages
-----------------------
- This release contains partial support for the Compaq/DEC `Ladebug' debugger.
Please send in bug reports listing remaining problems.
- Parsing of JDB data has been improved.
- DBX prompts for object file names are recognized.
User Interface
--------------
- `Breakpoint Properties', `Define Command', and `Debugger Settings'
have an `Apply' button that applies changes to text fields.
- In TTY mode, you can edit and complete the command line as in GDB.
(Uses GNU readline library.)
- Ctrl+E moves the cursor to the end of the line. For a `Run'
shortcut, use F2/F3 or Shift+Ctrl+E.
- DDD uses the locale as specified by the environment (such as $LANG).
This allows input of locale characters in DDD dialogs; error
messages may also come up in your locale. If you experience any
problems, set LANG=C when invoking DDD.
Plotting
--------
- If you have several indexed variables in a cluster (such as X[1],
X[3], and X[5]), DDD plots the cluster as 2-D plot, where the X axis
shows the index, and the Y axis shows the values. This is useful for
plotting array slices (see below).
Source Navigation
-----------------
- Using GDB, `Open Source' no longer automatically reads all shared
libraries of the debuggee; this took too much time with some programs.
There is an additional button that loads libraries.
Data exploration
----------------
- You can rotate structs, saving space by omitting the member names.
A rotated struct looks very much like a horizontal array.
- The last rotation setting is used for new displays and is saved
together with other DDD options.
- Array slices `ARRAY[FROM..TO]' are much better supported:
* By default, the displayed values are clustered and displayed like an
ordinary array.
* Array slices can be plotted, too (see `Plotting', above).
- You can use the FROM..TO notation in arbitrary values, and also multiple
times; `graph display 1..5 * 1..5' creates a multiplication table.
- To select multiple displays, it suffices that the selection rectangle
touches a display (rather than enclosing it entirely).
- The Display Editor has buttons for clustering and unclustering displays.
Running the Program
-------------------
- Breakpoint commands are also supported for DBX, Perl, and XDB.
- In Perl, DDD supports temporary breakpoints.
Settings
--------
- DDD saves the GDB source directory path with the current session.
- DDD saves the JDB class path only with the current session.
DDD 3.2 also incorporates all improvements and bug fixes from earlier releases.
