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
