Text Widget Leak

[Kevan Hashemi]

Dear TCL-MAC,

Daniel has fixed the leak in the text widget of 8.4.16-8.4.18, so I
expect the fix will be in 8.4.19. As he points out: it's not really a
leak, it's a failure to delete properly. He tracked the problem to an
apparant bug in an Apple routine.

Owen: I hear your concerns about bugs in TK. So far as I can tell, most
such bugs are the result of the TK code writers' efforts to keep up with
the evolution of the Apple graphical user interfaces. In my experience,
the bugs always get fixed within a couple of months, so long as we
provide the code-writers with a snippet of TK that will reproduce the
problem on their own machines.

I also remember well what it was like dealing with commercial compilers
and GUIs.

If I may paraphrase Mr. Churchill, it seems to me that open source
development is the worst form of development except for all those others
that have been tried.

Yours, Kevan

Well, some of them get fixed quickly -- fortunately including some of
the important ones. I've found workarounds for many others. Of the bugs
I've submitted on Tk 13 are still open and most of those are quite old
now.

But the text leak is by far the most serious problem I've personally
encountered recently (getting the mouse position wrong being the other,
and that may finally have been fixed in 8.4.15) and I'm very glad it has
been fixed.

Yes. I wish there was a business model that worked better. I would be
happy to pay for a GUI library if that money bought something better
than the open source alternatives. But as you point out open source is
often better than the commercial alternatives.
