If there's no translated PDF or the translated PDF fails and the item
has a DOI, check Zotero's Unpaywall mirror for possible sources and try
to download one of those.
Unlike with "Add Item by Identifier" and "Find Available PDF" in the
item context menu, this does not try the DOI/URL page, since it would
result in more data leakage and most of the time you'd be saving from
the DOI page already. We could consider offering it as an option, but
for it to be useful, you'd have to have an institutional subscription,
be on-campus or connected via VPN (for now), and be saving from
somewhere other than the main page.
A new connector endpoint, sessionProgress, takes the place of
attachmentProgress. Unlike attachmentProgress, sessionProgress can show
new attachments that have been added to the save, and with a little more
work should also be able to show when a parent item has been recognized
for a directly saved PDF.
This also adds support for custom PDF resolvers, available to all PDF
retrieval methods. I'll document those separately.
Closes#1542
If you had Quick Copy set to a missing translator, had a site-specific
Quick Copy setting, and loaded a page in the browser, the next click on
an item would result in a restart error.
- Show a clearer message on a certificate error that includes the
underlying error, which should make debugging much simpler. (No more
checking in a browser and hoping it's the same connection.)
- Mention proxy server in message on startup proxy-check failure
- Include link to connection-error KB page on sync connection failure
Closes#1191Closes#1513
Use zoteroproxycheck.s3.amazonaws.com of s3.amazonaws.com, both for
clarity and because the latter redirects, which makes it hard to test in
a browser after an SSL cert error.
If a proxy is required and we can't connect to S3, show the (sync) error
icon. For SSL certificate errors, which are the most common cause of
this, the panel includes a link to the SSL cert troubleshooting page.
A submitted database had a text userID with a trailing "A0. Not sure how
that happened -- it doesn't appear to be possible in current code -- but
it caused group permissions not to be properly synced.
- Add the ability to extract a PDF URL from a given webpage using the
translation framework
- Add the ability to get open-access PDFs from landing pages from
Unpaywall data in addition to direct PDF URLs
- Use the above functionality to improve PDF retrieval for "Add Item by
Identifier"
- Add "Find Available PDFs" option to the item context menu to retrieve
PDFs for existing items from the DOI or URL page or using Unpaywall
data. The option appears for single items with a DOI or URL and no PDF,
and it always appears when selecting multiple top-level items (but
skips ineligible items).
PDF extraction from DOI/URL pages will currently only work with
unauthenticated access (i.e., on-campus or VPN, but not via a web-based
proxy).
Supersedes and closes#948
