- Moved ::_get() and _set() from Collection/Search into DataObject, and
disabled in Item
- Don't disable new items after save. We now put new objects into the
DataObjects cache from save() so that changes made post-save are
picked up by other code using .get().
- Added 'skipCache' save() option to avoid reloading data on new objects
and adding them to the cache. (This will be used in syncing, where
objects might be in another library where they're not needed right
away.) Objects created with this option are instead disabled to
prevent reuse.
- Modified some tests to try to make sure we're reloading everything properly
after a save.
- Documented save() options
- Fixes some saving and erasing issues with collections and searches
- Adds Zotero.DataObject::eraseTx() to automatically start transaction,
and have .erase() log a warning like .save()
- Adds createUnsavedDataObject() and createDataObject() helper functions
for tests
It takes <1.5 seconds on my system, but it's taking over 30 seconds on
Travis. Might not be worth running it there, since almost anything that
would cause that to fail would cause the initialization to fail in the
first place.
The sync cache will have pristine copies of the existing versions of
local objects for better conflict resolution, but downloads will get
saved to the sync cache first before processing, so the cache needs to
be able to hold more than one version.
Replace Z.DataObjects::diff() with Z.DataObjectUtilities.diff(). Instead
of just returning two objects with the differing fields, the new diff()
generates a changeset with operations to apply with applyChanges(),
including at the array member level for collections and tags. This,
combined with cached pristine copies of objects, will allow for vastly
better conflict resolution, with automatic merging of non-conflicting
changes.
Creators currently don't show granular changes, and ordering might make
it too tough to do so. Relations diffing isn't yet implemented.
Also:
- Make .mode == 'patch' optional if .patchBase is provided.
- Remove requirement for item to be unchanged, which hopefully wasn't there for
a good reason
- Add a few tests, though more are needed
