hey everyone,

this is something that i have been looking to bring up for a while, so i thought i would kick off a discussion about moving to prototype 1.5 is silverstripe
i imagine the core devs have already discussed this to some extent

in my reporting project, i make use of 2 plugins that require the 1.5 branch of prototype, so this puts a bit of a personal motive behind this, but all that aside, this mildly significant update has been out for about 7 months, so i think it behooves us to see what can be done to adapt current scripts to be compatible

so here is what i propose, people post about their individual projects and why/how/if they are affected by the update
also input from the core devs would be great, as im sure they already know of incompatibilities in the core

the next issue is one that has come up in the past, but i believe that there is more to be discussed about it
the issue is javascript compression. there are a lot of good compressors out there, and i rarely hear convincing arguments that one is better than another
i personally feel good using dean's packers

we all know that there is a lot of js in silverstripe, and not everyone uses gzipping on their web servers, so i think distributing compressed scripts, or the option of using compressed scripts would be beneficial, maybe something in _config could specify to used prototype.js or prototype_compressed.js, etc

last issue that comes to mind is another one dealing with optimization
there has been a good amount of work done in the last year or so primarily on improving window.onload ready speed
it started with dean edwards and alex russell but it has grown quite a bit, and i think the most mature/robust incarnation is the fastinit script which combines a variety of improvements, the most notable of which is that onload does not wait for images to load

i think this would be a welcome addition to silverstripe, making the cms appear much more responsive in certain cases

anyway these are some of my thoughts, any discussion is appreciated

recap: prototype 1.5 -> compression -> onload optimization

Thanks for bringing these things up, take a look at the tow following posts for some background on this - Javascript Compressors and a off topic discussion on Prototype 1.5

In short I agree 100% with you that doing these things would be a great idea, however there would be a lot of work required. Regarding upgrading to prototype 1.5, I think this would be best done as we deploy the new interfaces as that is going to require a large amount of work in its own right.

The counter to this is if you think you can pull of a 1.5 upgrade with a few days work.. now, that would be pretty legendary You may want to talk with Elijah about this

Hi guys, I'm attaching a patch that should upgrade Prototype and Scriptacolous, I've left backwards compatible changes in prototype_improvements.js

This should work against 2.0.2

Sorry bout that, I though I'd uploaded it... its here anyway.
