LoadLogbookForExpedition() - remove the TROG and lbo things since we need the database for multiuser access? Or not? - profile the code to find bad repetitive things, of which there are many. - far too many uses of Django field dereferencing to get values, which is SLOW - Logbooks 1987, 1988, 1989 all crash on MySql - but not sqlite - with db constraint fail. Edit logbook to fix. - import/parse/re-export-as-html the 'artisanal-format' old logbooks so that we keep only a modern HTML05 format. Then we can retire the old parsers and reduce the volume of code here substantially. - rewrite to use generators rather than storing everything intermediate in lists - to reduce memory impact. - We should ensure logbook.html is utf-8 and stop this crap: file_in = open(logbookfile,'rb') txt = file_in.read().decode("latin1") - this is a slow and uncertain function: cave = getCaveByReference(caveRef) - use Fixtures https://docs.djangoproject.com/en/4.1/ref/django-admin/#django-admin-loaddata to cache data for old logbooks. New design needed, with a mechanism for flagging fixtures as outdated after edits.
