Phonegap SQLitePlugin
=====================
This is Joe Noon's fork of Phonegap-SQLitePlugin
This fork lives at: https://github.com/joenoon/Phonegap-SQLitePlugin
The original lives at: https://github.com/davibe/Phonegap-SQLitePlugin
This fork has largely diverged from the original, and is not a drop-in
replacement.
DISCLAIMER:
I'm brand new to objective-c, so there could be problems with my code!
Please tell me. joenoon@gmail.com
Added:
- obj-c:
- batch execution support
- query parameter binding
- perform after delay so js-objc call doesn't need to wait for response
- callbacks moved out of instance and into options of each method call
- path just takes filename, and path is put in Documents folder
- added rowsAffected, insertId
- success callback response is { insertId: x, rowsAffected: y, rows: z }
- error callback response is { message: x }
- js (coffeescript):
- new implementation
- first cut transaction support
- callbacks per-statement, even within transaction
- somewhat similar api to the webkit/phonegap default
- lawnchair adapter
Removed:
- quota limit webkit html5 db patching
- exit from app
- (I don't think either of these would make it through the approval process)
Other notes:
I played with the idea of batching responses into larger sets of
writeJavascript on a timer, however there was only a barely noticeable
performance gain. So I took it out, not worth it. However there is a
massive performance gain by batching on the client-side to minimize
PhoneGap.exec calls using the transaction support.
We are brand new to objective-c, so there could be problems with our code!
