Package: polipo
Version: 1.0.4.1-1.1
Severity: wishlist
I seed ~/.polipo-forbidden based on the "adblockplus" database[0]. I
updated this for the first time since 10 Jun 2010. Shortly after
this, I noticed that 1) polipo doesn't respond to most requests from
my browser[1]; and 2) polipo.log shows a new (I think) error:
Couldn't compile regex: 13.
Since this wasn't very helpful and "13" didn't appear to be a line
number, I checked the source. The message comes from forbidden.c[2];
13 is the value returned by regcomp(3).
The regcomp(3) manpage indicates that regerror(3) can be used to
generate a more detailed (i.e. useful) error message. Please use it.
