Cbbackupwrapper not working with passwords that contain parentheses

Couchbase Server
1

Hello,
My Couchbase password contains parentheses and that causes trouble with cbbackupwrapper (cbbackup works fine, though).

This is the command I’m running:
cbbackupwrapper http://HOST:8091 /backup-dir --username Administrator --password ‘xxxx(xxxxxxxx’ --mode diff --bucket-source bucket_name --single-node

This is the output:

Waiting for the backup to complete…
/bin/sh: 1: Syntax error: “(” unexpected
/bin/sh: 1: Syntax error: “(” unexpected
/bin/sh: 1: Syntax error: “(” unexpected

/bin/sh: 1: Syntax error: “(” unexpected
/bin/sh: 1: Syntax error: “(” unexpected
/bin/sh: 1: Syntax error: “(” unexpected
SUCCESSFULLY COMPLETED!

Needless to say the backup finishes too fast and isn’t completed successfully.

Ideas anyone?

It seems like a bug in the python script, it should really quote the password (and maybe other arguments) when building command line. This patch fixes the issue:

Working perfect. Thanks!
