The download failure rate gets skewed when the MD5's become out of date because folks try again right away, maybe even more than once and get the same failure.
The MD5Checker seems to work, but the CI server keeps hanging saving the artifacts of the flex-sdk-release build and then MD5Checker doesn't get to run. I upgraded Jenkins to try to reduce the hanging, but I just looked and noes flex-sdk is hung. It will help if, when the MD5Checker reports an error that folks jump in and update the sdk-installer-config-4.0.xml if it isn't during my work hours. But really, the theme remains that download reliability is poor. I'm starting to wonder if there is a bug in URLLoader that makes it less forgiving in large downloads. Someday I hope to find time to read more on how downloading is supposed to work. Maybe we need to implement some other, more reliable download mechanism. I'm also going to look into how much it would cost me to host pre-packaged downloads for the IDEs like Adobe did. Then, if you can download and unzip it, no further downloads are needed. -Alex On 8/24/14 6:49 PM, "Justin Mclean" <justinmcl...@me.com> wrote: >Hi, > >Just took a look at the installer errors in the last week. > > Overall there here were 707 errors and 702 successful installs, that's a >50% error rate and the error rate is higher on windows.
