[New-bugs-announce] [issue5803] email/quoprimime: encode and decode are very slow on large messages

[Dave Baggett]

New submission from Dave Baggett <jython at baggett.org>:

The implementation of encode and decode are slow, and scale nonlinearly
in the size of the message to be encoded/decoded.

 A simple fix is to use an array.array('c') and append to it, rather
than using string concatenation. This change makes the code more than an
order of magnitude faster.
