Some checks failed
📎 now picks any file (Android: Camera / Gallery / File; desktop: an
unfiltered dialog) and the desktop page accepts any dropped file. Photo and
screenshot formats up to 64 MB are still re-encoded and shown inline;
everything else is stored byte for byte on dufs beside the images and linked
as [name](url), shown as a row with its size that opens in the platform's
app (Android) or a new browser tab (desktop). BACKLOG.md rewrites file links
to ~/data/cloud/todo-images/ like image links.
There is no size cap, so no layer holds a file in memory: uploads and
downloads stream through DufsImageClient, writes land in a .tmp renamed when
whole (an interrupted download no longer leaves a truncated file that looks
done), the desktop page POSTs the browser's own Blob with fetch, and Android's
"File" uses file_picker, because file_selector's Android side reads the whole
file into memory on the UI thread. Verified with a 1 GB file end to end on
desktop (peak RSS +36 MB) and on an API 36 emulator.
The wrapper serves attachments from the origin that holds the GitHub token
and the notes, so only script-free types open inline (nosniff), the rest
download; writes carrying another site's Origin are refused (this also
closes cross-site overwrites of the backup files); and attachment routes run
concurrently so a long upload or a playing video cannot stall the page.
Also: cupertino_icons 2.0.0 (unused, but the freshness gate blocks the
pubspec otherwise), open_file 4.0.0 and file_picker 13.1.0 pinned.
