Subject: gplanarity: displays blank window

Date: Sat, 31 Oct 2009 14:40:15 -0500

[Message part 1 (text/plain, inline)]

Package: gplanarity
Version: 11496-2.2
Severity: important

Starting gplanarity with this configuration displays only a blank
window (of the default GTK+ background color) which does not obviously
respond to any input.  Closing the window exits the program normally.

This feels like some kind of non-gPlanarity-specific library
brokenness.  It's reproducible even after moving the old .gPlanarity
directory away, though I haven't tried it with a fully fresh user.

strace -ttt output is attached.

Subject: Re: gplanarity in Squeeze begins to become extremely slow in upper levels.

Date: Tue, 15 Mar 2011 05:54:48 -0400

Package: gplanarity
Version: 16723-1
Severity: normal

In Debian Squeeze gplanarity becomes extremely slow in upper levels of play.
It gets to the point it is not playable where the moving circles are moved with
the mouse, but only the mouse pointer moves and the circles have a delay of
about 3 to 5 seconds before the strings and circle moves.  This was not a
problem in Debian Lenny.  The game was only affected after the upgrade to
Squeeze.  Sorry, if I didn't follow a certain format for the report.  Any
questions please reply.

You didn't open a new bug report but posted a comment in a bug which is already
closed and is not related to your problem. Please see
http://www.debian.org/Bugs/Reporting to report a new bug.

About your problem, I cannot reproduce it with squeeze. Do you have the same
delays when playing other games, or does it happen only with gplanarity ?

Subject: blank window workaround patch works only by accident

Date: Wed, 23 Mar 2011 06:05:09 -0400

Hi folks,

I have a new 'release' of gPlanarity with a few new translations, and
a correct fix to the blank window bug.  See:
http://web.mit.edu/~xiphmont/Public/gPlanarity.html

The fix for this bug suggested in this bug report (553500) is not
correct and works by accident, meaning it could also break at any
time.

The bug is caused by a restriction/clarification in the GDK/Cairo
interaction API where a cairo target created for a given GDK window is
now only gauranteed to be valid for the span of a single GDK event.
gPlanarity had previously been caching a single cairo_t upon
allocation of the window and attempting to use it for all following
drawing operations.  It now allocates a cairo_t for the GDK window on
demand for each drawing op, then discards it.  That is the correct fix
to the bug.

Cheers!
Monty

Yes, I know my patch was not ideal. Thanks for fixing this bug properly, I'll
prepare a new package for Debian soon.

Thank you!  I didn't mean to sound harsh, just to the point :-)
(If anything I was annoyed at how the GDK documentation was silently
retconned after the background behavior in GDK changed.)

Cheers,
Monty
