Issue #12199 has been updated by Daniel Pittman.

Category set to augeas
Status changed from Unreviewed to Needs More Information

This seems like a reasonable request, but I have no idea how this could be 
represented in a way that won't be very strange, or cause other, deeper 
problems.

If you use Augeas, can you comment on what would work from your point of view 
about this?  How should it be expressed in the Puppet DSL?

Bug #12199: augeas "set" silently truncates values

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.
