Look for other profiles, from both apps (Firefox and Standalone), that
point to the data directory being migrated and update prefs.js in those
profiles to point to the new location.
Also reorganize code into Zotero.Profile and Zotero.DataDirectory
namespaces
And don't skip alerts in Zotero.alert() during automated tests. (That
was intended to avoid long timeouts after unexpected failures, but,
e.g., PDF metadata lookups (which are currently disabled in automated
tests) should just be mocked so they don't intermittently fail.)
Don't start the connector pipe (Mac/Linux), don't listen for IPC on the
command-line (Windows), and don't try to release Standalone's lock if DB is
busy when Firefox starts.
- Use custom exception for user-initiated sync cancellations, which can bubble
up to the sync runner -- this should help with a sync stop button (#915)
- Separate out deletions-downloading code
- Refactor delay generator handling on library version mismatch
- Clearer variable names
.contains() was removed in Firefox 48, but .includes() wasn't available until
40, so use indexOf() for now. We can start using .contains() once we no longer
need to support 38 ESR.
While trying to get translation and citing working with asynchronously
generated data, we realized that drag-and-drop support was going to
be...problematic. Firefox only supports synchronous methods for
providing drag data (unlike, it seems, the DataTransferItem interface
supported by Chrome), which means that we'd need to preload all relevant
data on item selection (bounded by export.quickCopy.dragLimit) and keep
the translate/cite methods synchronous (or maintain two separate
versions).
What we're trying instead is doing what I said in #518 we weren't going
to do: loading most object data on startup and leaving many more
functions synchronous. Essentially, this takes the various load*()
methods described in #518, moves them to startup, and makes them operate
on entire libraries rather than individual objects.
The obvious downside here (other than undoing much of the work of the
last many months) is that it increases startup time, potentially quite a
lot for larger libraries. On my laptop, with a 3,000-item library, this
adds about 3 seconds to startup time. I haven't yet tested with larger
libraries. But I'm hoping that we can optimize this further to reduce
that delay. Among other things, this is loading data for all libraries,
when it should be able to load data only for the library being viewed.
But this is also fundamentally just doing some SELECT queries and
storing the results, so it really shouldn't need to be that slow (though
performance may be bounded a bit here by XPCOM overhead).
If we can make this fast enough, it means that third-party plugins
should be able to remain much closer to their current designs. (Some
things, including saving, will still need to be made asynchronous.)
This mostly gets ZFS file syncing and file conflict resolution working
with the API sync process. WebDAV will need to be updated separately.
Known issues:
- File sync progress is temporarily gone
- File uploads can result in an unnecessary 412 loop on the next data
sync
- This causes Firefox to crash on one of my computers during tests,
which would be easier to debug if it produced a crash log.
Also:
- Adds httpd.js for use in tests when FakeXMLHttpRequest can't be used
(e.g., saveURI()).
- Adds some additional test data files for attachment tests
Also:
* _finalizeErase in Zotero.DataObject is now inheritable
* Call _initErase before starting a DB transaction
* removes Zotero.Libraries.add and Zotero.Libraries.remove (doesn't seem like this is used any more)
There's a lot more to do, and this isn't ready for actual usage, but the
basic functionality is mostly in place and has decent test coverage. It
can successfully upgrade a library last used with classic syncing and
pull down changes via the API. Uploading mostly works but is currently
disabled for safety until it has better test coverage.
Downloaded JSON is first saved to a cache table, which is then used to
populate other tables and later for generating PATCH requests and
automatically resolving conflicts (since it shows what was changed
locally and what was changed remotely). Objects with unmet dependencies
or unknown fields are skipped for now but don't block the rest of the
sync.
Some of the bigger remaining to-dos:
- Tests for uploading
- Re-do the preferences to get an API key
- File sync integration
- Full-text syncing integration
- Manual conflict resolution (though this already includes much smarter
conflict handling that automatically resolves many conflicts)
And use it in resetDB() test support function, mainly to allow
skipBundledFiles for resetDB calls. Translator installation and
initialization can take a long time, but tests that need a clean DB
don't necessarily rely on translators. Without this, running resetDB()
in beforeEach() for many tests is prohibitively slow.
Since modal windows (e.g., the Create Bib window and the Quick Copy site
editor window) can't use yield, style retrieval
(Zotero.Styles.getVisible()/getAll()) is now synchronous, depending on a
previous async Zotero.Styles.init(). The translator list is generated in
the prefs window and passed into the Quick Copy site editor, but it's
possible the translators API should be changed to make getTranslators()
synchronous with a prior init() as well.
- Simplified schema
- Tags are now added without reloading entire tag selector
- On my system, adding 400 tags to an item (separately, with the tag
selector updating each time) went from 59 seconds to 42. (Given that
it takes only 13 seconds with the tag selector closed, though,
there's clearly more work to be done.)
- Tag selector now uses HTML flexbox (in identical fashion, for now, but
with the possibility of fancier changes later, and with streamlined
logic thanks to the flexbox 'order' property)
- Various async fixes
- Tests
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.
