Bug Description

Hash: SHA1

I don't know what we broke in the tracking data-transferred case, but I
was just doing some testing with:

 bzr branch -Dbytes bzr+ssh://localhost/.... local

And it didn't report the number of bytes transferred. Checking in
~/.bzr.log shows that it thought there were 0 bytes transferred, which
is when it suppresses the message (though it shouldn't if you are
passing -Dbytes directly.)

I tested the same command with bzr 2.2.2 and the bytes transferred were
tracked correctly (as near as I could tell).

While the content is being transferred, it does seem to be aggregating
the number of bytes. So something between the active transport
transferring data, and the final logging of it has been broken.

I did some manual stepping back through old tags, and this broke between
bzr-2.3b1 and bzr-2.3b2.

I haven't been able to figure out what, exactly, is going on. But it
looks like the object that is getting 'report_transport_activity()'
calls, is *not* the same object that is getting
'log_transport_activity()' calls.

I wonder if this is the initialize() code screwing with state?

Some debugging. Inside the main() function in bzrlib/commands.py is where we are doing the logging. At the point where we are ready to run the command:

 ret = run_bzr_catch_errors(argv)
 (pdb) bzrlib.ui.ui_factory._progress_view
 <bzrlib.ui.text.TextProgressView object at 0x9ac42cc>

At the point where we are ready to print

 (pdb) bzrlib.ui.ui_factory._progress_view
 <bzrlib.ui.text.TextProgressView object at 0xa003f4c>

So something between when we start and when we finish is changing the _progress_view object. Note that I checked and the ui_factory object itself has not changed.

Found it in bzrlib.commands.py:

            return self.run(**all_cmd_args)
            # reset it, so that other commands run in the same process won't
            # inherit state

That final set_verbosity_level(0) resets the _progress_view state, and it happens *before* we fall all the way back out to main() to decide that we want to log how many bytes are transferred.

I have the fix written, and it should hit 2.3.1, I won't worry too much about Critical status.
