Richard W.M. Jones [Fri, 1 Apr 2011 14:50:33 +0000 (15:50 +0100)]
daemon: Introduce "pulse mode" progress events.

This introduces a new form of progress event, where we don't know how
much of the operation has taken place, but we nevertheless want to
send back some indication of activity.  Some progress bar indicators
directly support this, eg. GtkProgressBar where it is known as "pulse
mode".

A pulse mode progress message is a special backwards-compatible form
of the ordinary progress message.  No change is required in callers,
unless they want to add support for pulse mode.

The daemon sends:

 - zero or more progress messages with position = 0, total = 1
 - a single final progress message with position = total = 1

Note that the final progress message may not be sent if the call fails
and returns an error.  This is consistent with the behaviour of
ordinary progress messages.

The daemon allows two types of implementation.  Either you can just
call notify_progress (0, 1); ...; notify_progress (1, 1) as usual.

Or you can call the functions pulse_mode_start, pulse_mode_end and/or
pulse_mode_cancel (see documentation in daemon/daemon.h).  For this
second form of call, the guarantee is very weak: it *just* says the
daemon is still capable of doing something, and it doesn't imply that
if there is a subprocess that it is doing anything.  However this does
make it very easy to add pulse mode progress messages to all sorts of
existing calls that depend on long-running external commands.

To do: add a third variant that monitors a subprocess and only sends
back progress messages if it's doing something, where "doing
something" might indicate it's using CPU time or it's printing output.

proto: Fix both-ends-cancel case.

In the case where both ends cancel at the same time (eg. both ends
realize there are errors before or during the transfer), previously we
skipped sending back an error from the daemon, on the spurious basis
that the library would not need it (the library is cancelling because
of its own error).

However this is wrong: we should always send back an error message
from the daemon in order to preserve synchronization of the protocol.

A simple test case is:

  $ guestfish -N fs -m /dev/sda1 upload nosuchfile /
  libguestfs: error: open: nosuchfile: No such file or directory
  libguestfs: error: unexpected procedure number (66/282)

(Notice two things: there are errors at both ends, and the
loss of synchronization).

After applying this commit, the loss of synchronization does not occur
and we just see the library error:

  $ guestfish -N fs -m /dev/sda1 upload nosuchfile /
  libguestfs: error: open: nosuchfile: No such file or directory

The choice of displaying the library or the daemon error is fairly
arbitrary in this case -- it would be valid to display either or even
to combine them into one error.  Displaying the library error only
makes the code considerably simpler.

This commit also (re-)enables a test for this case.

proto: Fix FileIn ops that abort during the chunk upload stage.

As a previous, incorrect attempt to fix RHBZ#576879 we tried to
prevent the daemon from sending an error reply if the daemon had
cancelled the transfer.  This is wrong: the daemon should send an
error reply in these cases.

A simple test case is this:

  guestfish -N fs -m /dev/sda1 upload big-file /

(This fails because the target "/" is a directory, not a file.)
Prior to this commit, libguestfs would hang instead of printing an
error.  With this commit, libguestfs prints an error.

What is happening is:

  (1) Library is uploading
  a file                          (2) In the middle of the long
                                  upload, daemon detects an error.
                                  Daemon cancels.
  (3) Library detects cancel,
  sends cancel chunk, then waits
  for the error reply from the
  daemon.                         (4) Daemon is supposed to send
                                  an error reply message.

Because step (4) wasn't happening, uploads that failed like this would
hang in the library (waiting for the error message, while the daemon
was waiting for the next request).

This also adds a regression test.

This temporarily breaks the "both ends cancel" case (RHBZ#576879c5).
Therefore the test for that is disabled, and this is fixed in the next
patch in the series.

This partially reverts commit dc706a639eec16084c0618baf7bfde00c6565f63.

What's supposed to happen is this:

  (1) library sends
  request message              (2) daemon processes request
  first chunk of data          and sees that it will fail,
                               sends cancellation
                               (3) discards chunks of data
  (4) library sees daemon
  cancellation and stops
  sending chunks

It was going wrong in step (1), in guestfs___send_to_daemon.
In some (timing related) circumstances, send_to_daemon could
receive the cancellation before sending the first chunk, at
which point it would exit, *discarding the first chunk*.
This causes the daemon to fail in step (3) since it reads the
next request as if it was a chunk, thus losing synchronization.
(The protocol specifies that you always have to send at least
one chunk if there is a FileIn or FileOut parameter).

The patch changes guestfs___send_to_daemon so that if it detects
cancellation, it sends the remaining data in its output buffer
instead of discarding it.  (This also fixes another edge case
to do with sending partial data although I don't think we
ever saw that in practice).
