- refactor everything with some urgency, esp. parse_logbook_for_expedition()
|
||||
- Most of the time is during the database writing (13s out of 14s).
|
||||
|
||||
- Move a lot of non-db code from store_entry_into_database()
|
||||
into parse_logbook_for_expedition()
|
||||
|
||||
- call GetTripPersons at parsing time, not db writing time
|
||||
- this is a slow and uncertain function too: cave = getCaveByReference(caveRef)
|
||||
|
||||
- if I am certain that we are creating from scratch, don't use save_carefully() to
|
||||
create the Django objects. And I am, because I delete the outdated stuff.
|
||||
|
||||
- pre-compile all the heavily used regular expressions !
|
||||
|
||||
- break out the code that hits the database from that which parses the logbook
|
||||
so that the file-reading and parsing can be parallelized, while writing to the
|
||||
database remains serialized (sqlite is single-user).
|
||||
- refactor to get rid of the global 'logentries', very ugly indeed.
|
||||
|
||||
- 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

- replace explicit 1970 date with a constant EPOCH
|

|

- rewrite to use generators rather than storing everything intermediate in lists - to reduce memory impact.
