Incompatibility with Trac 1.4.2

[Ian.Goodacre@…]

I recently installed Trac 1.4.2 and MarkdownMacro from https://trac-hacks.org/browser/markdownmacro?rev=18008&format=zip but MarkdownMacro didn't work. I traced the failures to two issues with the plugin installed to plugins of my project:

1) The installation instructions refer to component tracmarkdown.macro.markdowneverywhere, but that did nothing for me. What worked for me was tracmarkdown.macro.markdownformatter. With the latter I was able to disable processing of markdown everywhere, leaving just the macro processor.

2) Processing markdown everywhere failed, resulting in blank pages, when markdown processing everywhere was enabled. I traced this to the tab_length argument to the markdown function. It was u'4', which was an incompatible type. Changing it to 4 worked and changing the call to set tab_length in format_to_markdown from env.config.get to env.config.getint returned 4 instead of u'4', which also worked.

I was working with a fresh install of Python 2.7.18 installed by asdf, in case that makes a difference, though it appears that env.config is Trac code and the get method of the Configuration class appears to be documented to return a string, though I don't know the code well and might be misunderstanding.
