no list of subtickets shown with Trac 1.4 ==> Genshi needed

[Daniel Musketa]

Installing and enabling the plugin works fine. I can enter parent tickets in the new field but the list of subtickets (or a link to the parent ticket) is not shown.

I am using the following Dockerfile (so you can easily reproduce the issue):

FROM debian:buster

ENV TRAC_ADMIN_NAME admin
ENV TRAC_PROJECT_NAME demo
ENV TRAC_DIR /var/local/trac
ENV DB_LINK sqlite:db/trac.db
EXPOSE 80

ENV DEBIAN_FRONTEND noninteractive
RUN apt update && apt install -y python-virtualenv && apt clean

RUN python -m virtualenv trac_env
RUN trac_env/bin/pip install --upgrade pip
RUN trac_env/bin/pip install Babel==2.9.1 Jinja2==2.11.3 Trac==1.4.3

RUN mkdir -p $TRAC_DIR
RUN trac_env/bin/trac-admin $TRAC_DIR initenv $TRAC_PROJECT_NAME $DB_LINK
RUN trac_env/bin/trac-admin $TRAC_DIR deploy /tmp/deploy
RUN mv /tmp/deploy/* $TRAC_DIR
RUN trac_env/bin/trac-admin $TRAC_DIR permission add $TRAC_ADMIN_NAME TRAC_ADMIN

RUN echo $TRAC_ADMIN_NAME:'$apr1$ehA79Brq$E75RuTlWc4Etzb2DkoMIm1' > $TRAC_DIR/.htpasswd # hunter2

RUN trac_env/bin/pip install TracSubTickets==0.5.4
RUN echo '\n\
[components] \n\
tracsubtickets.api.* = enabled \n\
tracsubtickets.web_ui.* = enabled \n\
' >> $TRAC_DIR/conf/trac.ini
RUN trac_env/bin/trac-admin $TRAC_DIR upgrade

CMD trac_env/bin/tracd -s $TRAC_DIR --basic-auth="*,$TRAC_DIR/.htpasswd,demo"

That's an installation issue. It is needed to install Genshi. This plugin still requires Genshi even if running on Trac 1.4.

Thank you!
After adding Genshi to the pip requirements, it works.
