Title:
mawk 1.3.3-17ubuntu2 incorrectly handles "/" in "[ ]" expressions
Status in mawk package in Ubuntu:
Confirmed
Status in mawk package in Debian:
New
Bug description:
Binary package hint: mawk
Description: Ubuntu 9.04
Release: 9.04
Package version: mawk 1.3.3-13ubuntu1
Whilst attempting to run a shell script to automate the build procedure for
an embedded platform I came across a parsing error in the mawk installation on
my Ubuntu 9.04 box. I followed this up with the script author, and then the
mawk maintainer, and determined that:
(a). The behavior of mawk 1.3.3-13ubuntu1 is incorrect
(b). The incorrect behavior exhibited by mawk 1.3.3-13ubuntu1 is not
exhibited by the upstream sources mawk-1.3.3-20090920 when built on my Ubuntu
box
The error case can be demonstrated using this script fragment:
for interpretter in gawk mawk;
do
echo "Running with $interpretter..."
echo
echo "diecimila.name=Arduino Diecimila, Duemilanove, or Nano w/ATmega168" | \
$interpretter -v FS== '{boardname=$2; gsub(/[^a-zA-Z0-9_,./():-]/, "",
boardname); print boardname }'
echo
done
When run using my system's mawk installation I get the following output:
Running with gawk...
ArduinoDiecimila,Duemilanove,orNanow/ATmega168
Running with mawk...
mawk: line 1: regular expression compile failed (bad class -- [], [^] or [)
[^a-zA-Z0-9_,.
mawk: line 1: syntax error at or near )
bash: echo: write error: Broken pipe
When run using the upstream mawk I get the following output:
Running with gawk...
ArduinoDiecimila,Duemilanove,orNanow/ATmega168
Running with ./mawk...
ArduinoDiecimila,Duemilanove,orNanow/ATmega168
For reference, I built the upstream mawk package as follows:
./compile && make
That is, I used whatever defaults the autoconf script picked for my
system.
