Equalify Iris 0.3.0

Equalify Iris 0.3.0

• The tagged version replaces the PDF at its own address. Links from email, other websites, bookmarks and search results now open the tagged PDF too, not just links on your pages. Hosts like Pantheon serve uploads without running WordPress, so a redirect could never reach them. The original is kept beside it as name-iris-original.pdf, and nothing in your posts is rewritten.
• Delete Iris-Tagged Version puts the original back. If the file was replaced since it was tagged (with a media-replace plugin, say), the new file stays and the screen says so.
• Deactivating the plugin no longer changes what visitors see. Tagged PDFs stay tagged. Deleting the plugin puts every original back; deleting a PDF from the media library deletes its kept original too.
• PDFs tagged by 0.2.x move by themselves. The background job moves each name-accessible.pdf to the PDF's own address, ten per site per run. If the original's file is gone, the copy takes its place; if the copy is gone, the PDF is sent to Iris again.
• Works on Pantheon's file system, which does not rename files: the tagged version is copied into place and checked, and the original is never left missing. The PDF's own address is cleared from Pantheon's CDN, for subdirectory sites under both addresses they serve uploads at.
• The media library shows whether each PDF is tagged, in a list-view column and on each PDF's details.

Not supported: plugins that move uploads to external storage (S3 and similar). Replaced a tagged PDF's file? Send it to Iris for tagging again.

Install: Network Admin → Plugins → Add New → Upload, then network-activate. Upgrading from 0.2.x: upload over it; tagged copies move to their PDFs' addresses over the next few background runs, with nothing to do. Outside Pantheon, purge any CDN that cached your PDFs, or hook equalify_iris_links_changed.
