Amahi Edge

Amahi Edge is the developer version of Amahi, with the very latest and greatest code in it. It lives in a branch of the Amahi Git repo, called

  amahi-edge

This page is about working notes for the latest in the development tree.

How to Get Amahi Edge Running

This procedure is the way to get Amahi 7 running in development. This has been tested with a clean Fedora 17 minimal install from the original DVD (without updates):

1. open a terminal window
2. as Root (su):
   1. enter the root password (not the one from the first user)
   2. yum groupinstall 'Development Tools', or for a shorter install do:
      • yum -y install make git mysql-devel sqlite-devel mysql-server gcc-c++ tar rpm-build
      • yum -y install ruby ruby-devel libxml2-devel libxslt-devel
   3. systemctl start mysqld.service
   4. gem install bundler
3. exit the root user and use a regular user. you will need to reinstall fedora if you skip this step :(
4. download the latest tarball
5. extract the tarball into your user folder use tar or your file manager-extract function
6. cd ~/amahi-7
7. bundle install (this will take a while and install all the necessary gems)
8. rake db:create this will ask for the mysql root password with a prompt ">"
   • if this is a fresh Fedora 17 install, your mysql server probably does not have a password, so just press Enter
   • if you set a password for the mysql root user, type it. Note that it will show a warning and echo the password!
   • if you are re-running this step and the db is already created, you can run rake db:drop first then create it again
9. rake db:migrate (this will get the database up to snuff)
10. rake db:seed (this will get a basic database setup)
11. rails s (this will start the rails server)

The development dashboard can be reached with your favorite browser at:

  http://localhost:3000

There is an initial user created called admin with password admin. Login should work out of the box.

To stop the development server, just hit Ctrl+C in the terminal where you started the server.

Core Amahi packages

The next step is getting hdactl running. First let's install the dependencies:

  yum -y install bind bind-utils caching-nameserver sudo  dhcp samba httpd
  yum -y install monit perl-Authen-PAM fpaste
  yum -y install ruby-mysql ruby-libs eruby ruby-augeas
  yum -y install ruby-irb ruby-racc rubygem-rdoc eruby-libs
  yum -y install perl-Authen-PAM perl-libwww-perl
  yum -y install cadaver php php-mysql perl-URI filesystem rubygem-passenger

Here is one binary, compiled on Fedora 17, for 64bits and only 64bits.

In addition, here is another binary for hda-platform, also compiled on Fedora 17, for 64bits and only 64bits, even though it's a noarch rpm. This is a temporary work-around.

Running Tests

A great way to contribute is to write tests. The spec tests are in the spec/ directory. To run them:

    rake spec

It will show you one dot per test passing. It will show test fails with F and display the error.

You may need to

    yum install rubygem-minitest

to get things to run properly for some reason that we did not root cause yet.

Old info for Amahi 6

First you need to get the latest git repository (see how on the Contribute-page)

After you've got the latest master branch you need to switch to the amahi-edge branch (and tell git to follow it on the remote server):

git checkout amahi-edge

The amahi-edge code uses a different database for it's data so we need to create one, copy the production data in it and migrate it to the new datamodel:

• Go to /path/to/git/clone/platform/platform
• Execute ./hda-create-db-and-user amahi_devel
• Go to /path/to/git/clone/platform/platform/html/script
• Execute ./db-duplicate hda_production amahi_devel
• Go to /path/to/git/clone/platform/platform/html
• Execute rake db:migrate

Now we have a working amahi-edge branch which can be used to develop features, gadgets, widgets and fix bugs.

To reach the amahi-edge branch you need to go to /path/to/git/clone/platform/platform/html and execute

./script/server

How to install one Gadget

If you have developed a new gadget or fixed some bugs on an existing one you can install it using:

• Go to /path/to/git/clone/platform/platform/html
• Execute rake gadgets:install source=/path/to/the/gadget/source, e.g.

         rake gadgets:install source=../../gadgets/gadget_last_modified_files

When there are errors after installing the gadget you can uninstall it using:

• Go to /path/to/git/clone/platform/platform/html
• Execute rake gadgets:uninstall source=/path/to/the/gadget/source

Tips

• Start with virtual machine snapshots. Take a snapshot of your VM at the beginning, in case you have to revert, and take a snapshot as you progress through milestones.
• If you do not have a VM, take a snapshot of your development database. You can use ./script/db-duplicate and ./script/db-restore (use with care!)
• Don't forget, the Amahi forum has a section for virtualization, in case you're looking for some input in that area.
