Get rid of data_access.js, at long last. Existing calls to
Zotero.getCollections() will need to be replaced with
Zotero.Collections.getByLibrary() or .getByParent().
Also removes Zotero.Collection::getCollections(), which is redundant
with Zotero.Collections.getByLibrary(), and Zotero.Collections.add().
The latter didn't didn't include a libraryID anyway, so code might as
well just use 'new Zotero.Collection' instead.
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.
'b' for *b*undled files
Translators and styles take a long time to install and initialize in
source installations, and they're unnecessary for many tests.
This shaves about 10 seconds off each test run for me on one system (and
that's with some help from filesystem caching).
0 allowed for some accidental behavior due to old code expecting NULL,
and it prevented easy checks (``if (!libraryID)``) for a passed
libraryID. Code now uses Zotero.Libraries.userLibraryID instead of a
hard-coded value (except in schema.js). Functions can still make
libraryID optional, but they should then use
Zotero.Libraries.userLibraryID if that's to mean the user library.
There might be some code that still expects 0 that I missed.
- Protocol handler extensions can now handle promises and can also make
data available as it's ready instead of all at once (e.g., reports now
output one entry at a time)
- zotero:// URL syntaxes are now more consistent and closer to the web
API (old URLs should work, but some may currently be broken)
Also:
- Code to generate server API, currently available for testing via
zotero://data URLs but eventually moving to HTTP -- zotero://data URLs match
web API URLs, with a different prefix for the personal library (/library vs.
/users/12345)
- Miscellaneous fixes to data objects
Under the hood:
- Extensions now return an AsyncChannel, which is an nsIChannel implementation
that takes a promise-yielding generator that returns a string,
nsIAsyncInputStream, or file that will be used for the channel's data
- New function Zotero.Utilities.Internal.getAsyncInputStream() takes a
generator that yields either promises or strings and returns an async input
stream filled with the yielded strings
- Zotero.Router parsers URLs and extract parameters
- Zotero.Item.toResponseJSON()
This required doing additional caching at startup (e.g., item types and fields)
so that various methods can remain synchronous.
This lets us switch back to using the current Sqlite.jsm. Previously we were
bundling the Fx24 version, which avoided freezes with locking_mode=EXCLUSIVE
with both sync and async queries.
Known broken things:
- Autocomplete
- Database backup
- UDFs (e.g., REGEXP function used in Zotero.DB.getNextName())
Promise-based rewrite of most of the codebase, with asynchronous database and file access -- see https://github.com/zotero/zotero/issues/518 for details.
WARNING: This includes backwards-incompatible schema changes.
An incomplete list of other changes:
- Schema overhaul
- Replace main tables with new versions with updated schema
- Enable real foreign key support and remove previous triggers
- Don't use NULLs for local libraryID, which broke the UNIQUE index
preventing object key duplication. All code (Zotero and third-party)
using NULL for the local library will need to be updated to use 0
instead (already done for Zotero code)
- Add 'compatibility' DB version that can be incremented manually to break DB
compatibility with previous versions. 'userdata' upgrades will no longer
automatically break compatibility.
- Demote creators and tags from first-class objects to item properties
- New API syncing properties
- 'synced'/'version' properties to data objects
- 'etag' to groups
- 'version' to libraries
- Create Zotero.DataObject that other objects inherit from
- Consolidate data object loading into Zotero.DataObjects
- Change object reloading so that only the loaded and changed parts of objects are reloaded, instead of reloading all data from the database (with some exceptions, including item primary data)
- Items and collections now have .parentItem and .parentKey properties, replacing item.getSource() and item.getSourceKey()
- New function Zotero.serial(fn), to wrap an async function such that all calls are run serially
- New function Zotero.Utilities.Internal.forEachChunkAsync(arr, chunkSize, func)
- Add tag selector loading message
- Various API and name changes, since everything was breaking anyway
Known broken things:
- Syncing (will be completely rewritten for API syncing)
- Translation architecture (needs promise-based rewrite)
- Duplicates view
- DB integrity check (from schema changes)
- Dragging (may be difficult to fix)
Lots of other big and little things are certainly broken, particularly with the UI, which can be affected by async code in all sorts of subtle ways.
Cmd on OS X, Shift on Windows/Linux
How do I not get to close a ticket for this?
Unfortunately on Windows it doesn't seem possible to set the cursor
effect to arbitrary states (see note in libraryTreeView.js::
_setDropEffect() for the gory details), so this just uses the default
cursor there. On OS X and Linux the cursor reflects the requested
action.
This should make it much easier to debug startup errors, particularly in
Standalone.
This also adds a general mechanism to set Zotero initialization options via
command-line flags.
- Close Zotero pane before database is closed prior to reload, instead
of waiting until reload is complete
- Show an error message if Zotero Standalone is not accessible when it
should be

Other changes:
- Factored out Zotero.Translators from Zotero.Translator. The latter
should be usable in the bookmarklet and connectors without changes.
- configOptions, displayOptions, and hiddenPrefs no longer copy on
read. I don't think this actually affects any existing code.
- Zotero.Translate._loadTranslator() now returns a promise
This change should improve Firefox startup time. If the Zotero pane is
opened before Zotero has initialized, the pane will be blocked with a
progress bar until it's done. Standalone currently does the same, but it
should be changed to just delay opening the window if possible.
The upgrade wizard has been disabled for schema upgrades, in the hope
that upgrades can be done in a way that won't break compatibility with
earlier versions (or that can at least be done in a way such that we can
put out point releases of the last major version that provide
compatibility during beta/post-upgrade periods).
This patch likely breaks many things, and definitely breaks connector
mode.
This change also removes upgrade steps for databases from Zotero 2.1b2
and earlier. Users with such databases will need to upgrade via Zotero
4.0.x first or delete their data directories and start anew. This should
only affect users who haven't opened Zotero since Nov. 2010.
- New tag colors support, with the ability to assign colors to up to 6
tags per library. Tags with colors assigned will show up at the top of
the tag selector and can be added to (and removed from) selected items
by pressing the 1-6 keys on the keyboard. The tags will show up as
color swatches before an item's title in the items list.
- Synced settings, with Notifier triggers when they change and
accessible via the API (currently restricted on the server to
'tagColors', but available for other things upon request)
- Silent DB upgrades for backwards-compatible changes. We'll do
something fancier with async DB queries in 4.0, but this will work for
changes that can be made without breaking compatibility with older
clients, like the creation of new tables. The 'userdata' value is
capped at 76, while further increments go to 'userdata2'.
TODO:
- Try to avoid jitter when redrawing swatches
- Optimize tag color images for retina displays
- Redo attachment dots in flat style?
- Clear all colors from an item with 0 (as in Thunderbird), but I don't
think we can do this without undo
- New promise-based architecture
- Library-specific file sync queues, allowing other libraries to
continue if there's an error in one library
- Library-specific sync errors, with error icons next to each library
- Changed file uploading in on-demand download mode, which had been missing
- On-demand download progress indicator in middle pane
- More accurate progress indicator
- Various tweaks and bug fixes
- Various future tweaks and bug fixes
