If a view or other resources are destroyed while a promise is being
resolved, subsequent code can fail. This is generally harmless, but it
results in unnecessary errors being logged to the console.
To address this, promises can use a new function,
Zotero.Promise.check(), to test whether a value is truthy or 0 and
automatically throw a specific error that's ignored by the unhandled
rejection handler if not.
Example usage:
getAsync().tap(() => Zotero.Promise.check(this.win));
If this.win is cleaned up while getAsync() is being resolved, subsequent
lines won't be run, and nothing will be logged to the console.
Change all attachment functions to take parameter objects, including a
'collections' property to assign collections. (Previously, calling code
assigned collections separately, which required a nested transaction,
which is no longer possible.)
Fixes#723, Can't attach files by dragging
Wait for the pane's collectionSelected() to finish before returning from
collectionTreeView select methods (e.g., selectLibrary()), and wait for
previous items view to finish loading before creating a new one in
collectionSelected(). This ensures that the items view has been created (though
not loaded) before returning from a select. The tree can still get a bit
confused switching between collections, but I think we're getting closer to
fixing that.
Also switch the items tree to use the same pattern.
This also fixes dragging items to collections (#731).
Groups were already being loaded for the collections list, so we might
as well just store them initially and let Zotero.Libraries.getName() be
a synchronous call.
- 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.
