Benchmarked

[Koaps Freeman]

Hi guys,

I wanted to share my latest little project with you.

While it's not totally camping specific, it does use camping as it's main
test bed.

https://github.com/koaps/benmark


Basically it's my attempt at seeing what ruby server does a decent job on
JRuby as a camping server.

Take a look and feel free to let me know of any improvements that can be
done.

Thanks

Camping Blog with Sequel, Thin and Rake

[Koaps Freeman]

Hi All,

I just wanted to pass along some code I did recently.

https://github.com/koaps/camping-thin-blog

It's basically the Camping example Blog modified to work with Sequel, Thin
Server and Rake migrations.

I mainly did this because I'm testing using Camping on JRuby and
Celluloid's Reel-Rack and since native extensions are problematic on
current JRuby, I needed an easy alternative to pg gem and Sequel
JDBC:Postgres isn't bad, though I could have used JDBC from AR.


As a side note, here's my Nginx/HAProxy setup I'm using to frontend the
Camping Apps with a backup server to host a static page if the app is down.

Awesome

I'll give that a shot.

Thanks

 Something like this should work:

 # config.ru:
 require 'camping'
 require 'camping/reloader'

 class CampingRunner
   def initialize(path, name)
 @reloader = Camping::Reloader.new(path)
 @name = name
   end

   def call(env)
 @reloader.reload
 app = @reloader.apps[@name]
 raise Could not find app: #{@name} if app.nil?
 app.call(env)
   end
 end

 run CampingRunner.new('blog.rb', :Blog)

Apache Passenger and Reloader

[Koaps Freeman]

Hi Guys,

I just started playing with camping and so far it's pretty awesomo.

After much messing around I was finally able to get Apache Passenger,
Camping and ActiveRecord to PostgreSQL working.

Re: Apache Passenger and Reloader

[Koaps Freeman]

Thanks for the reply David,

I thought about trying that also.

Right now this is just for home devel stuff so it doesn't need to be robust
or anything, I just develop on my laptop which is separate from the
webserver so I was hoping I could just upload stuff and the server reloads
without me having to actually be logged into it.

The restart.txt seems to be hit or miss which is why I didn't want to use
it.

Thanks

 Hello!
 I am running apache with passenger too and I couldn't find a way to have a
 reloader feature as of now..this said you might want to use apache proxy to
 run directly camping (e.g. when you test code) using the default webserver
 (e.g. thin). I am using that to avoid the continuous reload even on a live
 website  (http://1.ai) and it works very well.

 Oddly sometimes things do not work between thin and apache + passenger (it
 is rare but...) so I think you could use thin + apache proxy when you test
 your code live and apache + passenger for the code that you do not need to
 re-load several times ?

 Others might have better ideas for config.ru so just take my workaround
 as such !

Re: Apache Passenger and Reloader

[Koaps Freeman]

cool, I got that running so I will play with it. I guess as long as the
camping server stays up there's no issues, but if it goes down, and apache
sees that then I have to restart apache to recover.

No biggie, at least reloader is seeing the code changes and recovering from
errors.

Thanks again.

Now to figure out how to use camping and play with some code.

I need to figure out the proper way to setup a activerecord connection and
use it in my code.

I was able to make a db.rb which does a require 'active_record' and
establishes a connection.

I then have a Test class that inherits from ActiveRecord::Base.

I wasn't really sure the best way forward from there.

Because I wanted static content available and saw a post about using
Rack::Static I just setup my module with a Test.find(1) query to pull a
record from my DB

module Test
  $test = Test.find(1)
  use Rack::Static, :urls = ['/static']
end

Now in my views I have a line like:

p Pg query: #{$test.text}


It prints data from my db/

I'm just not sure if using a global is the right way to go about it.

I tried a instance variable (@test.text) but that didn't seem to work.
Still getting a handle on ruby OO.



Thanks

 I understand! To achieve exactly that just use thin on your remote
 webserver (and apache or nginx as proxy..if you need the setting I can try
 to help but you can certainly find it on google too) then you can just drop
 your script via FTP and it will auto reload remotely too. Even on the days
 where I had 1000+ daily visitors thin did work very well so I would use
 that vs. passenger (I do use passenger for the multi users hosting as it
 does have some benefits e.g. we also run PHP and Perl in parallel and give
 more choices to developers to run scrips in several languages in parallel).

 Another simple solution would be this: whenever you upload your script
 just upload restart.txt too and it will work. Sorry if this is not ideal
 but I don't think that there are other options with passenger + apache.
