Do we want Blobs here or disk-backed Files? We have existing infrastructure for in-memory blobs ...
(In reply to comment #1) > Do we want Blobs here or disk-backed Files? We have existing infrastructure > for in-memory blobs ... My current patch already uses in-memory blobs as a fallback. This bug is about an improvement of the fallback. Disk-backed blobs are required to handle huge files such as video media or ISO image. http://lists.w3.org/Archives/Public/public-webapps/2010OctDec/0334.html If we don't implement disk-backed blobs, we don't have to implement blobs in the first place. In-memory blobs have little advantage over arraybuffers (especially when bug 648997 is fixed).
Yup. I think we should do something better here. Even cooler would be if we for large memory-backed blobs streamed them to disk and morphed the blob into a disk-backed one. Possibly after some timeout allowing the blob to go away completely instead.
baku, wasn't this fixed back in Firefox 52 with bug 1202006 ?
Yes. This is fixed.
