Parses and imports logbooks in all their wonderful confusion
The Objectstore stuff is an initial attempt to see how we can migrate away from the Django database.
An idea which no longer seems sensible given that we rely on the database to do the multiuser bit.
# When we edit logbook entries, allow a "?" after any piece of data to say we've frigged it and
# it can be checked up later from the hard-copy if necessary; or it's not possible to determin (name, trip place, etc)
'''
todo='''
- Use the .shelve.db cache for all logbooks, not just individually
- refactor everything with some urgency, esp. LoadLogbookForExpedition()
- 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)
- the object store will need additional functions to replicate the persontrip calculation
and storage. For the moment we leave all that to be done in the django db
Concurrent synchronisation would be nice..
- DB lock currently prevents multiple threads for loading logbooks. But asyncio might work..?
- Put the object store 'trips' and the 'logdataissues' into TROG global object
