The Zotero.DataDirectory equivalents return string paths instead of nsIFile
instances, so some of these calls now just use Zotero.File.pathToFile(), which
can be removed when the surrounding code is updated to OS.File,
This is the recommended approach (since NetUtil can still do some main-thread
I/O for files) and avoids warnings in the console.
For getContentsAsync(), also sends nsIURIs and string URIs to
Zotero.HTTP.request(), which should be used instead.
This makes getBinaryContentsAsync() much slower (due to the conversion from an
array of bytes to a binary string), but it's only used in tests. For one test
that compares two large files, use MD5 instead.
If a version is returned for an item's full-text content but a 404 is returned
for the content itself (because it's missing in Elasticsearch for some reason),
don't throw an error.
Also remove legacy array comprehensions in fulltext and syncFullTextEngine test
files, which apparently weren't being run.
The test runner now downloads and caches the PDF tools for the current
platform within the test data directory and only redownloads them when
out of date, and it updates the download URL so that the full-text code
pulls from the cache directory via a file:// URL.
The installPDFTools() support function now installs the files directly
instead of going through the prefs, and a new uninstallPDFTools()
function removes the tools. Since the presence of the PDF tools can
affect other tests, tests that need the tools should install them in a
before() and uninstall them in an after(), leaving most tests to run
without PDF indexing.
This also adds a callback to the waitForWindow() support function. If a
modal dialog is opened, it blocks the next promise handler from running,
so a callback has to be used to interact with and close the dialog
immediately.
