Query String for cache-busting about sbt-resource-management HOT 9 CLOSED

Interesting. That would definitely be a problem (we don't use any caches in front of our stuff (yet)). The querystring addition is actually part of the Lift snippet, rather than this sbt plugin itself. The plugin provides the data to do the querystring addition.

That said, I may add a toggle option for the query string in the gist for the snippet so that that particular aspect is supported. Does that seem reasonable?

WARNING Failed to fully read heh.

Renaming the file is an interesting problem. At the moment we let the AWS handlers calculate the checksum for the file. I suppose we could do the calculation ourselves, continue to encode the versions the same way, and have a setting that toggles whether the filename includes the checksum or not. We can then maybe pass that setting on to the Lift app via System.setProperty and update the snippet gist to check that property and decide whether to append before the extension or after the query string depending on what it's set to.

I guess I don't see how that would work, if say, you're pushing the files up to S3. The filenames would have to be changed to add the MD5 hashes. I think it would need to be part of the sbt build process.

I haven't looked at the source yet, so I may just be misunderstanding what you're proposing.

That sounds like it would work.

The one complication I'm seeing is how to properly communicate the include-checksum-in-filename vs as querystring option to the application. A property won't really work because in production you don't usually run your application through sbt, so the plugin wouldn't get a chance to set the property.

Maybe it could be encoded in the versions file? Makes the format a little more complicated, but it could just be that the first line is a checksums-in-filename=true or =false to indicate which to do.

I assumed you would put it in the versions props file. Or, you could create a separate props file just for it.

I'll pick one. I'll try and push something for this either later today or tomorrow.

@eltimn If you want to give the above solution a shot, setting checksumInFile in ResourceCompile := true should now include the checksum in the filenames.

Going to go ahead and close this issue. In my tests, it produces results as required; let me know if you run into any issues.
