With the new release of sphinx 3.1.0, nova pdf docs build started failing with "! Dimension too large." error. That started failing since 10th June when the requirement added the new constraint for sphinx. Seems like somewhere TeX memory is exhausted during the pdf building (I think we are hitting this open sphinx bug[1]). While reproducing it locally I found that our giant policy sample file inclusion in pdf doc causing this error. - https://zuul.opendev.org/t/openstack/build/9c3e835ad5ee4842a07d77fdbaa6c97d/log/sphinx-build-pdf.log#7661 We did skip the sample policy file for pdf in doc/source/configuration/index.rst but did not do that in admin configuration file and it start giving the error now. With this fix, sample policy file in admin config also is included in html but not in pdf. Closes-Bug: #1883200 Change-Id: Iae143997138a5169a1e0fc76a74f9a0f09c03626
