The current approach to sending data back from the "doc-to-pixels" container is via mounted volumes. This was practical because we had essentially two streams to send. However, the Qubes implementation is simpler and has less attacker-controlled data passing, since error messages are not sent. Only the really needed data.

Personally, I want to move all the Qubes wrapper code within doc_to_pixels.py, since we plan to use the stdio methods in containers as well. Not something that important for now, but something to keep in mind. (source)

Tasks

  • change container logic to stream pages as they are converted
  • implement client-side timeouts (see also Qubes: Client-side timeouts #446)
  • deprecate json progress information add way to receive debug information when conversion fails (probably after the conversion fails)
  • deprecate the doc_to_pixels_qubes_wrapper.py since now both containers and Qubes will be streaming pages.

qubes: Add client-side timeouts
c3d7505 
Extend the client-side capabilities of the Qubes isolation provider, by
adding client-side timeout logic.

This implementation brings the same logic that we used server-side to
the client, by taking into account the original file size and the number
of pages that the server returns.

Since the code does not have the exact same insight as the server has,
the calculated timeouts are in two places:

1. The timeout for getting the number of pages. This timeout takes into
   account:
   * the disposable qube startup time, and
   * the time it takes to convert a file type to PDF
2. The total timeout for converting the PDF into pixels, in the same way
   that we do it on the server-side.

Besides these changes, we also ensure that partial reads (e.g., due to
EOF) are detected (see exact=... argument)

Some things that are not resolved in this commit are:
* We have both client-side and server-side timeouts for the first phase
  of the conversion. Once containers can stream data back to the
  application (see #443), these server-side timeouts can be removed.
* We do not show a proper error message when a timeout occurs. This will
  be part of the error handling PR (see #430)

Qubes: add test if MAX_PAGES is enforced in client
4a4b145 
Because the server also checks the MAX_PAGES limit, the test in base
would hide the fact that the client is not enforcing the limit. This
ensures that's not the case.

When the pages in containers are streamed (#443), then this test should
be in base.py.

Stream pages in containers (merge isolation providers)
04f8fa8 
Merge Qubes and Containers isolation providers into a superclass called
"ProcessBasedIsolationProviders" by streaming pages in containers for
exclusively in first conversion process. The commit is rather large due
to the multiple interdependencies of the code, making it difficult to
split into various commits.

The main conversion method (_convert) now in the superclass simply calls
two methods:
  - doc_to_pixels()
  - pixels_to_pdf()

Critically, doc_to_pixels is implemented in the superclass, diverging
only in a specialized method called "get_doc_to_pixels_proc()". This
method obtains the process responsible that communicates with the
isolation provider (container / disp VM) via `podman/docker` and qrexec
on Containers and Qubes respectively.

Known regressions:
  - progress reports stopped working on containers
