Pow fails with Rails 2.3.2 app.

[gt-sdi]

Trying to use Pow with several 2.3.2 apps. ... None are happy. All respond in the same way .... i.e. Get told that the app threw an exception when starting.

From Safari when trying to access the app via Pow:

Your Rack app raised an exception when Pow tried to run it.
Error: Response was not received
at Client._finishRequest (/Users/gtorn/Library/Application Support/Pow/Versions/0.3.1/node_modules/nack/lib/client.js:75:27)

at Client.emit (events.js:81:20)
at Array.0 (net.js:829:12)
at EventEmitter._tickCallback (node.js:126:26)

From the Pow log:

Interesting facts:

• Watching the app's dev log shows that the request reaches the app and it succeeds ... no exception
• App runs fine for under rackup
• Pow is happy with a barebones Rails 3 app.
• rvm in use ... and is up to date
• 2.3.2 apps using ruby 1.8.6-p420
• 3.0.7 app using ruby 1.9.2-p180

Any suggestions gratefully received ... happy to supply any further info requested.

Hope to get this working as Pow looks great!

You can't upgrade Rails to 2.3.11, or Ruby to 1.8.7? That stuff is WAAAAY out of date. 2.3.2 has some pretty huge security flaws...

I'd be kinda shocked if pow did actually support something so old. Then again, what do I know?

[gt-sdi]

Thanks Steve ... certainly don't disagree about the age ... unfortunately the app belongs to a client, so upgrading not within my scope. Since there general indication that Pow will work with "2.3" ... thought I'd try ... if it only works with 2.3.X onwards it would be handy to document this and save somebody else the pain ... there's a lot of "old" apps out there still.

Most unfortunate. I feel for you. :/

I'm pretty sure I used it with a 2.3.8 app, but mine are all 2.3.11 now, so I'm not 100% sure.
