Release Notes Summary: Generating graphs of catalogs (Eg: puppet apply --graph) now correctly handles resources with double quotes in the title.


Puppet generates invalid .dot files.
If a resource name contains a quoted string the name is not escaped in the .dot file.

Example content generated by puppet:

    "Postgresql_psql[GRANT ALL ON DATABASE "puppetdb" TO "puppetdb"]" [
        fontsize = 8,
        label = "Postgresql_psql[GRANT ALL ON DATABASE "puppetdb" TO "puppetdb"]"

resulting in something like this:

Correctly escaped it would look like this:

    "Postgresql_psql[GRANT ALL ON DATABASE \"puppetdb\" TO \"puppetdb\"]" [
        fontsize = 8,
        label = "Postgresql_psql[GRANT ALL ON DATABASE \"puppetdb\" TO \"puppetdb\"]"

The behavior has been reproduced with Puppet 3.6.1 and 3.6.2

There is a ticket in the old system for this bug, with a stalled pull request.

Is this the ticket we discussed in IAC?

Comment by Reid Vandewiele [ 2014/12/31 ]

[~bcornils] No, I was talking about PUP-914.

Beth Cornils I ran into this too generating a graph using the agent running on master. Is there any concern that introduction of graphs into the UI might draw users to try --graph with the agent?

Comment by Verne Lindner [ 2015/07/23 ]

Scott Walker I'm not following your comment about UI graphs and CL --graph use: would you explain what the concern is?

Comment by Scott Walker [ 2015/07/24 ]

Verne Lindner This ticket captures a bug in which the agent can generate dot files that aren't syntactically valid. If you use "--graph" on the master agent you get an example - in that case because of some unescaped quotes. My rationale is: the graph is now much more visible and so maybe customers are more likely to try out the --graph option on the agent. If they try it on their master in PE 2015.2 they'll run into the bug straight away.

Beth Cornils I hadn't thought of deprecating - I like it. There's probably still value in expanded_relationships.dot for agent debugging purposes but there's less reason to use it compared with the others.

Problem still exist with Puppet 5 but the symptoms are not the same: dot(1) complains that the .dot file is invalid:

λ dot /var/puppet/state/graphs/relationships.dot
Error: /var/puppet/state/graphs/relationships.dot: syntax error in line 5765 near '"'

The line 5765 says:

λ sed -e '5765!d' /var/puppet/state/graphs/relationships.dot
label = "Postgresql_psql[CREATE DATABASE "ejabberd"]"
