This is a long running thread but I came across some recent updates on why Transfer (under load like on init) may be crapping out reliably:
http://cfmlblog.adamcameron.me/2014/04/ye-olde-xmlsearche-bugge.html What Adam describes is exactly the error I get in XMLFileReader when it blows up. Errors like: Failed to XMLSearch(/transfer/objectDefinitions/package[@name='theme']/object[@name='filter']) in XMLFileReader.cfc due to: [Expression] Unable to process the result of the XMLSearch for ''. I couldn't wrap my head around how it had an Xpath search but thought it was ''. What's interesting is that Model-Glue has a similar XML loader but it is single threaded on startup so it doesn't manifest itself there. Here's the source issue which was described as far back as 2008: http://house-of-fusion.10909.n7.nabble.com/XMLSearch-not-thread-safe-td65967.html And here is the Adobe bugbase issue for the xmlSearch wackiness: https://bugbase.adobe.com/index.cfm?event=bug&id=3739102 I have long considered rewriting the Transfer config file from XML to JSON due to the XML errors and it looks like this would work. Another option would be to perform a duplicate() on the XML before running xmlSearch which fixes the problem (but introduces a performance problem) in the house of fusion thread. You would add it here in XMLFileReader.cfc: results.addAll(xmlSearch(duplicate(collection[counter]), arguments.xpath)); In my limited testing, it appears that xmlSearch() on the config is only done the first time a particular object is instantiated. On my local laptop with a 1330-line XML file, the duplicate() takes 4-7ms. I'm going to push to production and see if this solves my issues but based on Adam Cameron's test case, it sounds like it does. While I have no hair left, I'm sure glad to see there really is an issue. Now I'm just pissed that for 4+ years Adobe has allowed something like this to exist. :\ Brian -- -- Before posting questions to the group please read: http://groups.google.com/group/transfer-dev/web/how-to-ask-support-questions-on-transfer Try out the new Transfer ORM Custom Google Search: http://www.google.com/cse/home?cx=002375903941309441958:2s7wbd5ocb8 You received this message because you are subscribed to the Google Groups "transfer-dev" group.
