Re: [EP-tech] auto-X.Y.Z.css

Hi John and Yuri,

This is the bane of my life as well, having to tell users to make sure they "hard refresh" the page before complaining something is not appearing/working as expected.  So having a fix for this will save me a lot of back and forth because I can be confident caching is not an issue.

Therefore, I have created this GitHub issue:

https://github.com/eprints/eprints3.4/issues/220

I have half written this already, it should not take too long to complete but may take a while to test to be confident it will do the job.

Regards

David Newman

As a (hopefully useful) side note, the Apache Rewrite ruleset will honour URLs for the auto css and _javascript_ that match e.g.

style/auto-3.3.10.css

style/auto-3.3.101.css

style/auto-3.3.10999.css

style/auto-3.3.100000.css

- any amount of digits (but only digits) before the '.css' or '.js'.

 

This can be used to force newer versions of the auto- files into browsers.

 

For recent versions of EPrints, I think you can copy lib/cfg.d/template_core.pl into the archive config file.

I would suggest changing this line:

href ="" $repo->current_url( path => "static", "style/auto-".EPrints->human_version.".css" ),

to:

href ="" $repo->current_url( path => "static", "style/auto-".EPrints->human_version."1.css" ), #note '1' before '.css'

 

Next time you need to force a different auto CSS or JS file, update the digit, or remove it!

 

For older versions of EPrints (3.3.10, possibly beyond), where the loading of config files from various different directories worked a little differently, and overriding files from lib/cfg.d/ wasn't as simple as copying them to the local config, you could make a lovely hack, intercepting the template pins and adding extra digits to them:

https://gist.github.com/jesusbagpuss/c5ae75d8cbafb902af8299ec57101d8c

 

I'm not /recommending/ the above hack - but we had it running like that without incident on 3.3.10 for a number of years!

 

Cheers,

John

Hi Yuri,

This is in lib/cfg.d/template_core.pl.  This file may also be in your archive's cfg/cfg.d/ directory or possibly even the flavours/pub_lib/cfg.d/ directory if you are on 3.4. 

This is the block of code you need to update (around line 39):

 $head->appendChild( $repo->xml->create_element( "link",
            rel => "stylesheet",
            type => "text/css",
            href ="" $repo->current_url( path => "static", "style/auto-".EPrints->human_version.".css" ),
        ) );

Regards

Hi!
 
  where's the code/template that generates the link in the head to
auto-X.Y.Z.css? I've modified it, but it is cached in the browser for a
month. I need to change it in order to people to get the changes without
asking them to clear the cache.
 
Thanks!
