NSPersistentDocument, Export (Save As) and wal/shm
OS X application, Yosemite (host and target), Xcode 6.1, all-Swift. If you
duplicate (save-as) an existing document, the new document appears on disk with
external journaling files (SHM, WAL).
It is impossible to state how undesirable this is without descending into
sarcasm.
The solutions I’ve seen from a web search are a year or more old, and have
proven ineffective.
What is the current thinking on this? This is another of those things that are
so conspicuous that I must be missing something obvious.
Details below the fold.

This concern seems to have been perking along since the introduction of
Mavericks.
One commenter said DTS volunteered these solutions:
1. Continue to use the Mountain Lion SDK for Mavericks development.
2. Swizzle something. I stopped reading.
Time’s run out on those.
A year ago, it was suggested on this list that the persistent-document subclass
should override the method for which the Swift signature is:
configurePersistentStoreCoordinatorForURL(_: NSURL!,
ofType: String!,
modelConfiguration: String?,
storeOptions: [NSObject : AnyObject]!,
error: NSErrorPointer) - Bool
… and pass @{ NSSQLitePragmasOption : @{ @journal_mode : @DELETE } } as
storeOptions: to super. With that pragma set, SQLite is supposed to suppress
the journal files.
An account of the strong-typing nightmare would veer once again into sarcasm.
I’m unhappy about assuming storeOptions will always be nil.
Here is my attempt:
```
let newOpts = [NSSQLitePragmasOption : [journal_mode : DELETE]]
// Also suggested:
// let newOpts = [JOURNAL:DELETE]
// This doesn’t work, either.
return super.configurePersistentStoreCoordinatorForURL(url,
ofType: fileType,modelConfiguration: configuration,
storeOptions: newOpts, error: error)
```
The breakpoint at the return line fires. newOpts has the expected content. I
still get WAL and SHM files. Using … [journal_mode : OFF]] does no better.

I just noticed this the other day (in 10.9.5) after switching my app from 10.8 SDK to 10.9 SDK (for the v2 gatekeeper changes). Pathetic that it's not fixed in 10.10!

I guess it says a lot about the state of NSPersistentDocument. :( Check out Mike Abdullah's BSManagedDocument if you can.

Jerry Krinock's solutions, that you no doubt found googling, seem to be working for me, but I don't like swizzling if I can avoid it. I actually just opened a DTS incident on this the other day, no word back yet. Will follow up here. Cheers, -- Sean McBride, B.
