Hi! I had a prolbem with Graphviz Plugin v0.6.7 and trac 0.10, I first wanted to create a ticket at tac-hacks, but the spam-filter didn't let me :-) So I paste the text here, sorry for the formatting: If run with trac 0.10, and Python 2.4 `GraphvizMacro.render_macro()` throws exceptions. According to trac 0.10 release notes, ""everything is unicode"" now, and that seems to be the problem. * sha_key = sha.new(self.processor + self.processor_options + content).hexdigest() throws `UnicodeDecodeError` * I tried to correct this in the form: sha_key = sha.new((self.processor + self.processor_options + content).encode('latin1', 'replace')).hexdigest() * this works, but after that there occurs an error in `GraphvizMacro.launch()` at p_in.writelines() So it seems to be a more thorough problem. I also tried to correct the '''writelines()''' problem with '''input.encode(...)''', it worked in some way, but after that the temporary .png files had 0 length, so the plugin didn't work either. So, unicode strings in trac 0.10 seem to mess up everything. Unfortunately, I don't know graphviz and the plugin good enough to correct the problem myself. By the way, if you only use ascii characters in the graphviz macro definition, everything works. Istvan",defect,closed,normal,GraphvizPlugin,normal,fixed,,stevie_30@…,0.10
