E.g., if a .pdf is really an HTML file, we try to load it in a hidden
browser (because we properly detect the content type), but then the .pdf
extension causes the hidden browser to launch it via the OS and the
hidden browser never finishes loading it. This adds a 5-second timeout
to abort the process.
When the associated-files pref is enabled, Add Item by Identifier uses a
Zotero Unpaywall mirror to find available open-access PDFs. No details
about the contents of searches are logged.
For each PDF with an associated URL in the Downloaded directory, we were
copying all files in the directory (!) to the attachment's storage
directory. (Zotero imports always have files in separate directories,
and this was a function used to save both single files and HTML
snapshots.)
We'll clean up the extra files in a separate step.
If "Place imported collections and items into new collection" is
unchecked, previously imported collections will be reused when they're
in the right place in the hierarchy rather than creating new ones.
Use the new wizard for all imports (even if no Mendeley DB), and add a
page with a "Place imported collections and items into new collection"
option. If deselected, collections are added to the library root.
If there's a single PDF file and a single PDF URL and the file exists,
make an imported_url attachment instead of separate file and linked_url
attachments.
Addresses #1451
Accept Mendeley SQLite databases via File → Import… and perform a
direct import, including collections, timestamps, notes, attachments,
and extracted annotations.
When a Mendeley database is present, File → Import… shows a wizard that
lets you choose between a file and Mendeley for the source, and choosing
the latter shows a list of available databases in the Mendeley data
directory.
Known fields that aren't valid for a type are stored in Extra.
Files in the Mendeley 'Downloaded' folder are stored. Files elsewhere
are linked.
Previously you could use Zotero.DBConnection to open another database in
the data directory, but not one stored elsewhere in the filesystem. This
allows an absolute path to be passed instead. Various operations
(backups, corrupt DB recovery, pragma commands) are disabled for
external databases.
