Issue #2597 has been updated by Nigel Kersten.
My .dot files are so enormous they're bloody impossible to debug correctly. Running something like the above script is so much more practical. I guess I just don't quite get how although we can't tell what the dependency cycle is internally, (as Luke just said at puppet camp) it's this trivial to grab the debug output and exactly pin-point the problem. ---------------------------------------- Feature #2597: Dependency cycle information should be more useful. http://projects.reductivelabs.com/issues/2597 Author: Nigel Kersten Status: Needs more information Priority: Normal Assigned to: Nigel Kersten Category: plumbing Target version: Rowlf Affected version: 0.25.0 Keywords: Branch: Here's a recent dependency cycle error message

dependency is here. I've been using pygraph to make this a bit more sane like: <pre> #!/usr/bin/python2.5 import pygraph import re change_arrows_quote = re.compile( '(.*) => (.*)') f = '/tmp/foo' the_str = open(f).read() the_str = the_str.replace(", ", "\n") the_str = the_str.replace(";","") the_str = the_str.replace("\"","") the_str = change_arrows_quote.sub(r'"\1" -> "\2"', the_str) the_str = "digraph Cycles {\n%s\n}" % the_str suspect = pygraph.readwrite.dot.read(the_str) print pygraph.algorithms.cycles.find_cycle(suspect) </pre> which works out that the cycle is in <code>['"Exec[apt_update]"']</code> It would be awesome if we could make the puppet dependency cycle error message point to exactly where the dependency cycle is. -- You have received this notification because you have either subscribed to it, or are involved in it.
