Interaction with the console has been a problem in our avocado
tests. In some cases, the expected string does not match in the
output, causing the test to fail with a timeout. These were worked
around by sleeping before reading the console and even with SSH
connections in some places.
To fix, process the console output char by char and not with
readline. This routine was largely inspired by console_wait() in
tests/vm/basevm.py.

Sorry for being picky (yay, bike shed painting!), but it's a little bit hard
to distinguish these "found" markers in the console.log from the lines that
just contain the normal output.
Maybe we could use some funky unicode character instead? For example:
console_logger.debug('🔎 %s', msg)
or:
console_logger.debug('✅ %s', msg)
?
Or maybe just indent the normal lines, i.e. in the _console_read() function
you could do this instead:
console_logger.debug(' %s', lines[0])
so that the "found" string is more visually separated?
Or maybe even combine the two approaches?
Thanks,
Thomas

Decoding this as 'latin1' is going to mangle any output
that is not represented by a single-byte UTF-8 codepoint.
You can't simply switch this to 'utf8' though, as in the
socket.recv(1) call you're only reading a single byte,
and you can't guarantee that can be decoded if its part
of a multi-byte sequence.
I think you need to read into a bytearray, instead of
reading into a string. Then convert 'expect' into a
bytearray too, and compare bytes for a match, thus
avoiding problem of partial utf8 sequence decoding
errors.

In the commit message you talk about a problem with non-matched
text, and timeouts causing failure.
IIUC, the key difference between this code and the use of readline()
is that this code is checking for a match in the partial line. ie we
don't need to wait for a newline to arrive anymore.
That's an interesting difference, but its not obviously correlated
with the commit message description.

Drop the SSH connection which was introduced in the avocado tests to
workaround read issues when interacting with console.

What about that EXTRA_BOOTARGS stuff? Is it not required/wanted in the new

These were introduced in the avocado tests to workaround read issues
when interacting with console. They are no longer necessary and we can
use the expected "login:" string now.

Could we please wait for the shell prompt here now? i.e.:
exec_command_and_wait_for_pattern(self,
'i2cset -y 3 0x42 0x64 0x00 0xaa i', '#')
or something similar?
With such a fix included:
