Thanks Steve, I'll investigate those options Lara
-----Original Message----- From: Steve Lawrence <slawre...@apache.org> Sent: Thursday, August 3, 2023 1:20 PM To: users@daffodil.apache.org Subject: Re: blob api issues in 3.5.0 I've tracked this down to being caused by enabling full validation. If you change it to limited or off, configuring blob attributes should work as expected. Unfortunately, there isn't really a great alternative. You could change the java.io.tmpdir property to change the directory, but you can't change the prefix/suffix, and changing that could potentially affect other things. I've added some additional low level details on the cause here: https://usg02.safelinks.protection.office365.us/?url=https%3A%2F%2Fissues.apache.org%2Fjira%2Fbrowse%2FDAFFODIL-2837&data=05%7C01%7Clara.blatchford%40nteligen.com%7Cdad4521505064950f07e08db9445ea53%7C379c214c5c944e86a6062d047675f02a%7C0%7C0%7C638266800238607241%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=xWypt7g9LqExL0O5JOt4ZLkLuH24eSmLuAauJ4h9gDc%3D&reserved=0 Fortunately, the fix should be pretty small and straightforward.
