Bug #12199: augeas "set" silently truncates values

Branch:
A simple augeas { '...': changes => 'set ... xxx' } can fail to put the
complete value into the target while wrongly reporting a successful application.
Example manifest:
define puppet::conf ($ensure) {
augeas {
"puppet.conf_${name}" :
changes => "set
/files/etc/puppet/puppet.conf/${name} ${ensure}" ;
"puppet.conf_${name}_sq" :
changes => "set
/files/etc/puppet/puppet.conf/${name}_sq '${ensure}'" ;
"puppet.conf_${name}_dq" :
changes => "set
/files/etc/puppet/puppet.conf/${name}_dq \"${ensure}\"" ;
}
}
puppet::conf {
"agent/server" :
ensure => 'puppetmaster-dev.edvbus' ;
"agent/pluginsync" :
ensure => 'true' ;
"test/sq" :
ensure => "'" ;
"test/sqsq" :
ensure => "''" ;
"test/sqsqsq" :
ensure => "'''" ;
"test/sqsqsqsq" :
ensure => "''''" ;
"test/dq" :
ensure => '"' ;
"test/dqdq" :
ensure => '""' ;
"test/dqdqdq" :
ensure => '"""' ;
"test/dqdqdqdq" :
ensure => '""""' ;
"test/truncated_dq" :
ensure => '"s"bc"d"ef' ;
"test/truncated_sq" :
ensure => "'s'bc'd'ef" ;
"test/truncated_dq_mix" :
ensure => '"s"bc\'d\'ef' ;
"test/truncated_sq_mix" :
ensure => "'s'bc\"d\"ef" ;
"test/truncated_space" :
ensure => "before after" ;
"test/mix" :
ensure => "a\"b'c\"d'e" ;
}
Result in /etc/puppet/puppet.conf (sorted for convenience):
[test]
dqdqdqdq_sq=""""
dqdqdq_sq="""
dqdq_sq=""
dq_sq="
mix=a"b'c"d'e
mix_dq=a
mix_sq=a"b
sq_dq='
sqsq_dq=''
sqsqsq_dq='''
sqsqsqsq_dq=''''
truncated_dq_mix=s
truncated_dq_mix_sq="s"bc
truncated_dq=s
truncated_dq_sq="s"bc"d"ef
truncated_space=before
truncated_space_dq=before after
truncated_space_sq=before after
truncated_sq_dq='s'bc'd'ef
truncated_sq_mix_dq='s'bc
truncated_sq_mix=s
truncated_sq=s
As you can see, depending on the used quoting style, different parts of the
values are silently truncated. Only values that cannot be written at all into
the file cause an error.
I've tested this with 2.6. on squeeze and 2.7.10 on centos 6.2 with the same
results.
