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.
