Changes between 2.4 and 2.4.p1

• Bug Fix: Some proc breakpoints were not firing if they are defined in a namespace.
• Bug Fix: Some command line options were not taking effect.
• Bug Fix: Accelerator keys stopped working (reported by Sanjay Shanker)
• Bug Fix: Users were unable to load any source file that didn't have a .tcl extension (reported by Holger Kanwischer)
• Bug Fix: Tuba wasn't handling more than one level of symlinks to the installation directory (reported and fixed by Harald Kirsch)
• Bug Fix: Fixed a very obscure bug in the runtime instrumentation of dynamic procs (apparently not obscure enough) (reported by Harald Kirsch)
• Bug Fix: More fixes to the run time instrumenter.
• Bug Fix for Windows: made wish80 the default interpreter (suggested by Ronald J. Maddalena)
• Bug Fix for Windows: the Show Console and Hide Console menu options under Debugger now show and hide the console of the application being debugged, not the Tuba GUI. (reported by Uwe Dierolf)
• Administration: Tuba has moved to a new web site: http://www.geocities.com/SiliconValley/Ridge/2549/tuba/. Made all the appropriate documentation changes.
• Documentation Change: The main web page for Tuba underwent a small facelift. Also, I included instructions on how to set up an association for session files to bring up Tuba on Windows platforms.

Changes between 2.3 and 2.4

• Internal Change: tuba GUI was moved into a namespace so it would work better with other external libraries
• Bug Fix: the caching of instrumented files and the logic of when to use a cached file is now more intelligent. This fixes these bugs:
• the proc list and list of valid breakpoint lines were empty when using a cached file.
• any option change that would result in a different instrumentation was ignored and an old cache file pulled up.
• Bug Fix: a state model was introduced and commands are activated and deactivated according to the state. This will prevent, for instance, you from running the "step into" command when there is no program loaded.
• New Feature: You can enter proc exclusion expressions. Any proc that matches any of the expressions (using [string match]), then that proc is not instrumented and is effectively disabled from being stepped into or setting a breakpoint inside. These exclusions are saved in your session files. External changes:
• Added command line option -e <excl_file> which tells tuba to look in the file excl_file to get a list of proc exclusions expressions.
• Added entry in Options menu Proc Exclusions... This brings up a dialog box to interactively edit the proc exclusion expressions.
• Added section in user's guide discussing exclusions.
• New Feature: Sessions. You can now save your debug sessions, and load them back up, retaining the following pieces of information:
• the program being debugged
• program arguments
• working directory
• the interpreter
• line breakpoints
• proc breakpoints
• proc exclusions
• all options from the options menu
• Session external changes:
• New menu entries in the Debugger menu button:
• Open Session
• Save Session
• Save Session As
• New command line option -s <sessionfile> to start the debugger with the given session.
• Added section in user's guide discussing sessions.
• There is a sample session file in examples/example0.ses. Load this with the -s option or from Debugger -> Open Session...
• Bug Fix: Tuba now asks you if it's okay to kill a running app via the Exit, Load program, Restart, and Open Session menu commands.
• Internal Change: I redesigned the format of the .tubarc startup file. Tuba will detect the old version and convert it for you, but it will ask you if you want to save the conversion. If you don't you'll get that message every time you start up Tuba. Once you convert, the old tuba versions won't be able to read it. A backup will be made if you save the converted startup file.
• New Feature: The Options menu has a Locations... entry. This brings up a dialog box for entering default directories. Currently, this includes:
• cache directory
• sessions directory
• Bug Fix: I redesigned the status line (now two lines). Here are some new behaviors:
• Those loooong filenames now sit in a scrollable entry field so the window doesn't keep growing and shrinking when the file changes
• I added the current line number (finally)
• I added a second line which contains the currently displayed file. This should end the confusion about the original file entry, which is the current debugger position, not necessarily what the file is in the window currently
• The second line also contains the current session name, if there is one.
• I removed the source level field. I needed more space and I'm not sure anyone really cares what source level they're at. It might come back when I revamp the whole GUI.
• New Feature: You now have the option to keep existing breakpoints when you restart a program.
• Bug Fix: Made the breakpoint toggling logic smarter. Can now set breakpoints on procs inside a namespace, and tuba now handles cases where a statement and a proc appear on the same line; tuba brings up a dialog to ask exactly you want done. There's an example of this in examples/example0.tcl
• Bug Fix: Error interception changes:
• The status line is now updated with the information when Tuba intercepts an error
• Tuba will NOT intercept an error if there is a catch somewhere in the call stack. It assumes that the app will handle the error. This behavior is configurable under the Options menu.
• Bug Fix: Some Tk applications just drop off the end and let the implicit event loop in wish's main() to wait for all the windows to be destroyed. Tuba now detects this situation and will display a message that the app has finished and is in an event loop.
• Bug Fix: The current line (the source line highlighted in yellow) now goes away while the app is running and comes back when the app is stopped. This makes it easier for the user to tell who is running: the app or the debugger GUI.
• Bug Fix: Restarting and loading a new app will now kill all extra windows like the proc list, stack, etc.
• Bug Fix: Another parser bug fixed; the parsers were not properly handling the token  "\{".

Changes between 2.2 and 2.3

• All changes from 2.2.p1, p2, and p3 added
• Split out the instrumenter and made it a general purpose utility. This will eventually be available as a separate package.
• Instrumenter now supports caching of instrumented files. This dramatically speeds up repeated debugging on files that don't change. Interface changes:
• Added command line option -nc to do no caching
• Added command line option -c <dir> to set dir as the cache dir instead of default tuba/cache
• Added command line option -purge to purge cache directory before starting
• Added entry in Options menu Caching to turn on/off instrumented file caching
• Now supports run-time instrumentation which provides superior parsing for "tricky" Tcl code. Will slow down execution, though. Interface changes:
• Added entries in Options menu to choose load-time or run-time instrumenting. Changes to this will not take effect until the next load or restart.
• Added command line option -R to choose run-time instrumenting (load-time is the default)
• The testinstrumenter.tcl script has been rewritten to be a generic driver of the new instrumenter package. See the man page testinstrumenter.man.html for the complete poop.
• Parser language (Tcl or C) is now an option in the Options menu. Changes to this do not take effect until the next load or restart.
• Made the debugger source window taller.
• More parser bug fixes.
• Added an experimental replacement parser. This parser has the same interface, and is slightly faster and much easier to maintain. It will be the standard parser after it gets some "stick" time. The default is still the old parser. Interface changes:
• added new option -X to access the new parser
• added new Option menu entry "Experimental parser" to turn on/off the use of the experimental parser
• Can set the working directory from command line using -w <dir> option. If <dir> is "", then Tuba will use the directory of the program being debugged.
• Added a Tuba man page tuba.man.html.
• Updated the Users Guide to reflect all changes in versions 2.2 and 2.3.

Changes between Tuba 2.2.p2 and 2.2.p3

• Escaped newline parser fix was not put into the C++ parser. This patch rectifies this.

Changes between Tuba 2.2.p1 and 2.2.p2

• Removed advupdate.tcl and advupdate.so from the distribution as it is no longer needed.
• Fixed a parser bug regarding ending brackets inside a quote when beginning bracket is outside quotes.
• Fixed referenced directory name in toplevel README.

Changes between 2.2 and 2.2.p1

• Bug Fix: balloonhelp windows were coming up in upper left corner on Windows.
• New Feature: The windows version now has show/hide console menu options under the Debugger menu button (provided by Scott Beasley)
• New Feature: Tuba now remembers your last working directory and arguments entries when you loaded the program. The restart dialog will reflect these (provided by Scott Beasley).
• New Feature: Key accelerators for the stepping commands (provided by Scott Beasley). Currently these are hardcoded; they will be easily configurable in a future release. Here are the mappings:
• F5 - Continue
• F6 - Step Into
• F7 - Step Over
• F8 - Stop
• Bug Fix: Couldn't load programs from paths with spaces in them, or use an interpreter that lived in a path with a space.
• Bug Fix: Tuba was interfering with applications that had file event handlers. Had to redesign the mechanism of getting the STOP command. Now uses an extra port (uses original port + 1).
• Bug Fix: The instrumenter sometimes was not properly handling an escaped newline. Fixed both the Tcl and C++ parsers.
• New Feature: After selecting a program in the load program dialog via the browse button, the working directory field is automatically filled in with the directory of the program (provided by Scott Beasley).
• New Feature: The load program and restart dialogs now have Browse buttons for the interpreter field.
