[Sugar-devel] Support for EPUB with Read in sugar-jhbuild?

[James Simmons]

Sayamindu,

I'm still working on my e-book book and not being able to read EPUBs
in Read under sugar-jhbuild has become a blocker for me.  I'm trying
to figure out what's wrong but print statements don't seem to ever
come out.  The only clue I've got is the stack trace I already sent to
you.

The code that runs the method that's failing looks like this:

        mimetype = mime.get_for_file(filepath)
        if mimetype == 'application/epub+zip':
            if not _EPUB_SUPPORT:
                self.close()
            self._epub = True
            self._setup_epub_viewer()
            self._document = epubadapter.EpubDocument(self._view,
filepath.replace('file://', ''))
        else:
            self._setup_evince_viewer()
            try:
                self._document = evince.factory_get_document(filepath)
            except GError, e:
                _logger.error('Can not load document: %s', e)
                return

I don't know what self.close() does.  It isn't enough to stop the
lines following from running and failing.

I did notice one odd thing.  epubpadapter.py is in the same directory
as readactivity.py, but epubadapter does an import of epubview and
that file is NOT in the same directory, but in a subdirectory called
epubview.  So that might be someting.
