Wookey has now moved 'expoweb' from mercurial to git largely "as-is". Mark Shinwell has said that he will help on the loser (survex files) migration to git.

<p>Sam was a bit overworked in trying to get an entire university to work remotely during Covid lockdown so Philip [Sargent] started on the python2/3 conversion and got troggle on django 1.7 to work on python 3.5 and then 3.8. He then did the slog of migrating it through the django versions up to 1.11.29 - the last version before django 2.0 . 1.11.29 is an LTS (long term support) version of django. In doing this we had to retreat to python3.7 due to a django plugin incompatibility. <p>Sam was a bit overworked in trying to get an entire university to work remotely during Covid lockdown so Philip [Sargent] started on the python2/3 conversion and got troggle on django 1.7 to work on python 3.5 and then 3.8.

In the course of these migrations several unused or partly-used django plugins were dropped as they caused migration problems (notably staticfiles) and the plug-ins pillow, django-registration, six and sqlparse were brought up to recent versions. This was all done with pip in a python venv (virtual environment) on a Windows 10 machine running ubuntu 20.04 under WSL (Windows Systems for Linux) v1.

<p>Missing troggle functions were repaired and partly-implemented pages, such as the list of all cavers and their surveyed passages, were finished and made to work. The logbook parsing acquired a cacheing system to re-load pre-parsed files. The survex file parsing was completely rebuilt to reduce the excessive memory footprint. While doing so the parser was extended to cover nearly the full range of survex syntax and modified to parse, but not store, all the survey stations locations. A great many unused classes and some partly written code ideas were deleted. <p>Missing troggle functions were repaired and partly-implemented pages, such as the list of all cavers and their surveyed passages, were finished and made to work.

<p>Wookey upgraded debian on the server from 9 <var>stretch</var> to 10 <var>buster</var> and we got the python3 development of troggle running as the public version (with some http:// and https:// glitches) by 23rd July. <var>Buster</var> will be in-support definitely until June 2024 so we are rather pleased to be on a "not ancient" version of the operating system at last. This concided with a last tweak at improving the full cave data file import so now it runs on the development system in ~80 seconds. Which is considerably more useful than the ~5 hours it was taking earlier this year. <p>Wookey upgraded debian on the server from 9 <var>stretch</var> to 10 <var>buster</var> and we got the python3 development of troggle running as the public version (with some http:// and https:// glitches) by 23rd July. <var>Buster</var> will be in-support definitely until June 2024 so we are rather pleased to be on a "not ancient" version of the operating system at last.

Django 2.2 LTS is a long-term stable relase which will be in-support by Django until April next year. Wookey discovered and ran the Django system testsuite on the Debian server thus enabling us to use a necessary (but obstensibly outdated) link between Django and the database MariaDB.
