Pow is a zero-config Rack server for Mac OS X.

Pow Web Site - User's Manual - Annotated Source Code - 2-Minute Screencast

---

Current Version: 0.6.0

To install or upgrade Pow, open a terminal and run this command:

$ curl get.pow.cx | sh

To set up a Rack app, just symlink it into ~/.pow:

$ cd ~/.pow
$ ln -s /path/to/myapp

That's it! Your app will be up and running at http://myapp.test/. See the user's manual for more information.

pow's Issues

bundled node executable is x86_64 only

There are a few Core Duo OSX systems floating around... It can be hacked around, after the install fails comment out everything between the "Create the Pow directory structure" and "Create the ~/.pow symlink" sections (inclusive), and then copy or symlink a local build of 'node' into ~/Library/Application Support/Versions/Current/bin/ and run the script again.. it all seems to work...

Default umask and permission of ~/Library/LaunchAgents/cx.pow.powd.plist

I've got a default umask of 002 (rather than the standard 022). When ~/Library/LaunchAgents/cx.pow.powd.plist was created, it used my umask, and then wouldn't load because launchctl [apparently] doesn't like a file that's group-writable.

Solution: chmod 644 ~/Library/LaunchAgents/cx.pow.powd.plist after the file is installed.

Support installation via Homebrew

I'd like to support installation via Homebrew. I'm worried it'll introduce a second step to the installation process, though.

Anyone have a good idea where to start?

Support installation from behind a proxy server

I can do the first curl call from the instructions by adding my own proxy flags but there's another curl call in the resulting shell script that doesn't have my proxy settings and therefore causes the installation to fail.

I can get around it by downloading the shell script, modifying the curl call with my proxy flags and then running that but it kind of undermines the whole, nice simple one line installation process.

Ideally the shell script it downloads could somehow inherit my proxy flags from my original call but I doubt something like that would be possible. I think this might be a fairly widespread issue for all us poor souls behind a corporate firewall.

empty POW_DOMAIN gives weird result

On our DNS some names point to 127.0.0.1 because we use them for development. I figured setting POW_DOMAIN to "" would enable me to lauch them with pow, but pow still gobbles the last character.

export POW_DOMAIN=""
http://eat.io
error: "Symlink your application to eat.i first"

no such file to load -- sinatra

I have an old app that is not using bundler which requires sinatra, but pow can't load it.

Sinatra is installed system-wide, so I'm not sure if in order to use pow I have to use bundler?

rvm/zsh trouble

I have RVM but not necessarily an .rvmrc in my application's root. In this situation I couldn't get a Rails app to start, and in the logs would get something like:

[Thu, 07 Apr 2011 20:14:30 GMT] DEBUG nack worker 7374 spawned
[Thu, 07 Apr 2011 20:14:30 GMT] WARNING Could not find activesupport-3.0.3 in any of the sources
[Thu, 07 Apr 2011 20:14:30 GMT] WARNING Try running `bundle install`.
[Thu, 07 Apr 2011 20:14:30 GMT] DEBUG nack worker exited

By creating an .rvmrc file, even if empty, everything was fine.

Don't unlink tmp/restart.txt

Subdomains are not resolving for ccTLD-like POW_DOMAINS

When setting the ~/.powconfig file with something like this:

export POW_DOMAINS=dev,dev.il

and then killing the pow process for restarting, x.example.dev resolves (as expected), but x.example.dev.il does not.

Show a welcome page after installing Pow

Pow's install script should open your browser to a welcome page with instructions on how to set up your first app.

Support ruby-debug

Some issues are just easier to visualize within a debugger

quiting pow process following initial install via ActivityMonitor hangs OS X

This occurred only once, when I tried to quit the Pow process following initial install of Pow. I did not reconfigure Pow.
After getting my machine rebooted, I'm able to quit the process successfully. OS X v. 10.6.6.

unable to load bundled gems from github

Any gems referred to in your Rails Gemfile that are located using git://<gitpath> will prevent your app from loading via Pow. bundle install run in app directory succeeds without errors.

Bundler::GitError: git://<gitpath> is not checked out. Please run bundle install

Application won't start (YAML parse error?)

Here's a weird one for you.

The application starts fine using rails server (1.9 on a gemset, using .rvmrc)

Using pow, however (with /Users/bruce/Development/myproduct/web symlinked to /Users/bruce/.pow/myproduct):

ipfw rule breaks “Web Sharing” in Mac OS X

Prior to installing Pow, I had Web Sharing enabled in OS X to be able to serve static content from ~/Sites.

Now that Pow is installed, going to the address from the Sharing preference pane in Mac OS X (in my case that's http://192.168.50.103/~vladimir/) results in a “Pow: No Such Application” error page with the following message:

Symlink your application to 192.168.50 first.

This is unexpected to me because the URL I am attempting to visit is not a domain on .dev, which the resolver is set up for, yet Pow still tries to handle it. I understand that it is because all packets to a local IP, port 80 are redirected to Pow, but it seems confusing and breaks the ability to have static sites in ~/Sites.

Note: httpd was running (since Web Sharing was enabled) when I installed Pow, but the redirect rule did not take effect until after I restarted httpd (by disabling and then re-enabling Web Sharing). Before I restarted httpd requests kept going to it even after Pow was installed and the rule dropped into /Library/LaunchDaemons/cx.pow.firewall.plist.

lazy resolving of underscored project names

It would be nice to not have to type underscores in the domain if the project name has them. For example myappname.dev should resolve to the my_app_name project.

Any suggestions on how this could be accomplished? I'm new to a lot of this but really interested in learning.

I followed the instructions but it half-installed

I ran the command but no pow server starts (unless I am doing something wrong), and I can't see any of the paths from the documentation having arrived on the system anywhere (again unless I'm wrong). Any ideas?

Refuses to load on startup initially

I had no trouble getting Pow working on my MacBook Air, but for some unfathomable reason, it didn't work out of the box on my MacBook Pro.

I'm not sure what the cause of this was, but launchctl just refused to load ~/Library/LaunchAgents/cx.pow.powd.plist. I tried removing, reinstalling, repairing disk permissions, chmod'ing the plist to 644, etc. Even if I tried loading it manually with:

launchctl load ~/Library/LaunchAgents/cx.pow.powd.plist

# output:
nothing found to load

Only after I did this did it work:

launchctl load -Fw ~/Library/LaunchAgents/cx.pow.powd.plist

Now it seems to launch on system startup, and without the "-Fw". Any idea what could cause this? Is it maybe worth adding -Fw to the install script when it launches Pow for the first time?

Thanks, Pow is awesome.

Apache virtual hosts don't work after installing pow

Hi there,

I have been running virtual hosts on my Mac for developing PHP sites. I have installed Pow and now my previous virtual host sites display a message "This domain isn’t set up yet. Symlink your application to local.mydomain.c first."

Is this something to do with the ports that they're not able to run together?

Thanks.

How to install Pow from scratch

first off... awesome work 37Signals, this is really COOL! I just wanted to get this up ASAP, so I did not dig into issues, just quickly read some of the issues folks ran into, and I had already intended to manually install V8, Node, Redis as I'm working thru learning the technologies... ok so I have not double checked my steps. but they should give folks an idea of what needs to be done if they are unsure about what is going on underneath the installation

send_file from rails hangs indefinitely

When using send_file from rails (3.0.5 and 3.0.6 confirmed) the files never finish sending.

Here's a transcript to reproduce:

# gem install rails sqlite3
rails new send_file_bug
cd send_file_bug
cat > app/controllers/bug_controller.rb
class BugController < ApplicationController
  def index
    send_file Rails.root + "public/images/rails.png", :type => "image/png", :disposition => "inline"
  end
end
^D
cat > config/routes.rb
SendFileBug::Application.routes.draw do
  match ':controller(/:action(/:id(.:format)))'
end
^D
cd ~/.pow
ln -s $OLDPWD
curl -O -v http://send_file_bug.dev/bug

If you load the URL in your browser, you'll see that it does send the image, but the request never completes.

Load both .powenv and .powrc if present

There should be one environment file that can be checked in to source control and another that can be used for local or private environment variables.

Homebrew Formula

Is it possible to create a homebrew formula?

It will be easier to just type:
brew install pow

rvm gemsets not working as expected

I use gemsets extensively to work on multiple projects on the same dev machine. I'm finding that any projects that use gems that are not in the global gemset are failing to launch with missing gem errors (bundler is complaining).

Getting OS X equiv of blue-screen of death when using Pow over VPN

Pow works great when I'm not on VPN, but after about 30 secs of having my Cisco VPN turned on, OS X takes a dump. I tried to find some logs inside of Console, but can't get anything that's worth posting here. I suspect the issue is with Pow's DNS server clashing with Cisco VPNs'. Anyone else able to test this out?

Don't require config.ru for serving static sites

Right now it's possible to serve static sites with Pow, but only if you have a config.ru like this:
run lambda { [404, {"Content-Type" => "text/plain"}, ["Not Found"]] }

It'd be nice to eliminate that requirement.

TypeError: Object ... has no method 'split'

Hi

I'm trying to run a Rails 2.3.10 app and I get the erro below. Meanwhile I'm trying to write a failing test case, but I'm still figuring out how to use cake.

Meanwhile, I edit the lines 257-261 on nack/lib/client.js from:

        for (k in rawHeaders) {
          vs = rawHeaders[k];
          v = vs.split("\n");
          this.headers[k] = v.length > 0 ? v.join("\r\n" + k + ": ") : vs;
        }

to

        for (k in rawHeaders) {
          vs = rawHeaders[k];
          this.headers[k] = vs;
        }

and I could run the app.

The error is this:

Domain aliasing

This may be possible to do in resolver i don't know, when dealing with things such as Facebook connect you need to use a real domain or sub domain or Facebook won't give you the oauth tokens, what i usually do is pop dev.foo.com in my hosts file and then it will pass me the cookie, is there anyway i can alias foo.com to foo.dev?

Install fails with "Permission Denied"

Symlink to hostname mapping should be case-insensitive

I had a folder MyApp on my desktop and created a symlink of the folder in the .pow directory like this: ln -s /Users/errorhandler/Desktop/MyApp when I went to http://MyApp.dev I got Symlink your application to myapp first. message but when I changed the MyApp folder to myapp and removed the symlink and did the symlink again it worked, so it would seem that Pow doesn't look for symlinks starting with capitals

Threadsafe support?

Any chance of getting theadsafe support?

Compatibility with Ruby 1.9 installed as /usr/bin/ruby

In order for the application to work with Ruby 1.9.2, I had to make a few changes to bin/pow:

#!/usr/bin/ruby
require 'pathname'
ENV['POW_BIN'] = (bin = Pathname.new(__FILE__).realpath).to_s
root = bin.dirname.parent
exec root.join("bin/node").to_s, root.join("lib/command.js").to_s, *ARGV

Otherwise you get:

*** Installing Pow 0.2.2...
*** Installing local configuration files...
/Users/eric/Library/Application Support/Pow/Current/bin/pow:3:in `[]=': can't convert Pathname into String (TypeError)
from /Users/eric/Library/Application Support/Pow/Current/bin/pow:3:in `<main>'

After adding the manual string conversion I was able to finish installation and get a first app up and running without issue.

npm install --dev fails

Just cloned and tried to npm install --dev, but things blow up.

Output log is here: https://gist.github.com/908729

Can't tell if it's something on my end or if there's a dep issue, but thought I'd bring it up and see. Looks like it's expecting a coffee-script dir in the node_modules dir but not finding it?

Better handling of non-zero exit status in .powenv/.powrc

Uninstall doesn't work under iTerm

If I run the uninstall script (curl get.pow.cx/uninstall.sh | sh) under iTerm, I get the following error message:

sh: line 45: /dev/s000: No such file or directory

If I run the same command under the terminal, everything works fine.

JRuby app hangs

When I open sheldon.dev it just seems to hang[1], no noticable cpu load or io going on. It's a jruby app though (1.6.0), might that be an issue? rvm works fine, and I cd'd into ~/.pow/sheldon to tell rvm to trust that .rvmrc.

Another app with ruby-1.9.2 works great in pow!

Can't follow along w/ Screencast (no such file sinatra/base)

I'm trying to follow along with the screencast, but it won't boot resque because it claims it can't find the sinatra/base file:

/Users/estrathmeyer/Desktop/resque raised an exception during boot.

LoadError: no such file to load -- sinatra/base

Allow Environment Setting Per Symlink Host

I have an app that runs "n" number of instances. Each vhost in apache was set to use the same application directory and used "SetEnv foo bar" in each host to configure the app instance. Is this possible with pow using either the .powrc or .powenv files?

I have read thru the source code and do not see anything that would be available to me in these files that would allow me to know which worker/process I am firing up. My ~/.pow directory would be like this.

$ ls ~/.pow
foo.myapp -> /Users/kencollins/Repositories/myapp
bar.myapp -> /Users/kencollins/Repositories/myapp

Yes, it could be argued that my app should do this at the app level, but this ENV setting I need per host is a boot strap variable per app instance. Ideas?

Support .rvmrc

You can manually activate a Ruby version via rvm in .powrc:

source $HOME/.rvm/scripts/rvm
rvm use 1.9.2

But we should support .rvmrc files.

.dev resolver doesn't "register" properly

Editor's note: A few people have been unable to access .dev domains after installing Pow. It seems that in some cases the system doesn't immediately detect Pow's installation of a file in /etc/resolver. A temporary workaround is to open and save the /etc/resolver/dev file. The original message follows.
 

After Installing Pow I wasn't able to get an .dev domains to point to the pow server. I ran scutil --dns to see if the .dev resolver was being used at all, and it wasn't.

Opening /etc/resolver/dev and saving it again fixed this. Not sure why it was happening in the first place.

This happens with all native gems including nokogiri and sqlite3:

Better error message if both public/index.html and config.ru are missing

Pow used to show a nice error message if config.ru wasn't present, but since adding support for serving static sites, it just shows the default 404 handler. Let's show an informative message if both public/index.html and config.ru are missing.

Getting "Cannot Get /" for Rails site after symlinking a site

Hi,

I shut down the Apache Server I'd had running on port 80. I installed pow using the script from the http://get.pow.cx, and then created a symlink for the Rails 2.3 app. When I tried to access the URL for the site, "http://example.dev" resulted in a 404 error and a message saying "Cannot get /".

Better error message when json gem is missing from Gemfile in 1.8

Pow is not taking .rvmrc under account

In a small project of mine using a .rvmrc to switch to ruby1.9.2, Pow fails to make the switch
