Description

This issue is originally reported at trac:#11184.

When an element with i18n:msg attribute has last element which has $var as contents and it is translated with "aaa [1:%(name)s] zzz", got IndexError: pop from empty list.

    def test_translate_i18n_msg_ticket_404_regression(self):
        tmpl = MarkupTemplate("""<html xmlns:py="http://genshi.edgewall.org/"
            xmlns:i18n="http://genshi.edgewall.org/i18n">
          <h1 i18n:msg="name">text <a>$name</a></h1>
        </html>""")
        gettext = lambda s: u'head [1:%(name)s] tail'
        translator = Translator(gettext)
        translator.setup(tmpl)
        self.assertEqual("""<html>
          <h1>head <a>NAME</a> tail</h1>
        </html>""", tmpl.generate(name='NAME').render())

Any reason not to apply this? I've the same issue http://trac.edgewall.org/ticket/11184. I have 0.7 installed.

Fix in r1242 with a very slightly revised patch. Backported to 0.7.x and 0.6.x in r1243 and r1244 respectively. Thanks for the patch (and the prodding by various people :).

Is it possible to update http://ftp.edgewall.com/pub/genshi/Genshi-0.7.tar.gz and also the complete download-page?

comment:7 Changed 18 months ago by hodgestar

New releases coming in the next week or so.

I'm also affected by this bug. Since Genshi 0.7 apparently will be in the upcoming Debian stable release ("Jessie"), I filed a bug there to cherry-pick r1243: 775746.
