radiospiel / imgio Goto Github PK

Hy,

I understand the use of Goliath to fight against IO related performance issues.
But there is a great project called sinatra-synchrony that uses Fibers in order to release IO bottlenecks.
You could simplify the whole project by removing Goliath and enable sinatra-synchrony.

Is there another specific reason why Goliath has been chosen?

If not, I would like to help migrating this project to sinatra-synchrony.

Cheers,

Lukas

I would like to see something which allows the user to construct workflows, and which allows the application
to define possible workflow steps in an easy to use syntax.

A workflow could be something like:

• fetch (GIF) image from URL
• extract frame NNN from image
• apply mask
• crop & zoom to fit
• convert to JPG

which, as an URL, could probably look like this:

http://<server>/jpg/70/fit/100x200/mask/frame/12/http://<src-url>

Any thoughts on this?

If we build imgio into a middleware, we could provide support to automatically rewrite image tags like so. From:

<img width="120" height="240" src="http://domain.com/an/image.png"> 

into

<img width="120" height="240" src="http://<myimageioserver>/120/240/http://domain.com/an/image.png"> 

Hy @radiospiel ,

I think your plans to provide imgio as a middleware are great.

To do so I wrote down a couple of thoughts.

Since Sinatra is able to run as a middleware, we just need it to adapt a little bit.

Furthermorw I think there should be two variants of imgio as gems.
One should be async and for latest environments running Ruby19 and another should include Ruby systems >=1.8.7.
The latter could also provide support for async mode, maybe using a queue and processes or something. But for a first shot, it'd be enough to have it running in sync.

Since I have some spare time, I'd like to step up and work on the Ruby19 as a middleware,

What do you think?

Cheers, Lukas

If the original server support expiration times, copy that times in the resulting image.
If the original server support e-tags, copy that e-tags from client to server.
