Missing these required gems:
  ci_reporter

So I installed the gem.

$ sudo gem install ci_reporter
Fetching: ci_reporter-1.6.5.gem (100%)
Successfully installed ci_reporter-1.6.5
1 gem installed

There was an error installing the documentation for ci_report:

(continuing with the rest of the installation)

But this error didn’t interfere with my starting the web server.

Anyway, I was curious what ci_report was all about.

CI::Reporter is an add-on to Test::Unit, RSpec and Cucumber that allows you to generate XML reports of your test, spec and/or feature runs. The resulting files can be read by a continuous integration system that understands Ant’s JUnit report XML format, thus allowing your CI system to track test/spec successes and failures.

It looks like CI::Reporter works best with projects that use a Rakefile along with the standard Rake::TestTask or Spec::Rake::SpecTask/RSpec::Core::RakeTask tasks for running tests or examples, respectively. This way, it hooks into Test::Unit or RSpec using environment variables recognized by these custom tasks to inject the CI::Reporter code into the test or spec runs.

There isn’t a fair amount of documentation on CI::Reporter yet, except: http://caldersphere.rubyforge.org/ci_reporter/

Missing these required gems:

Run `rake gems:install` to install the missing gems.

I don’t remember running into this problem before.

$ rake gem:install daemons

The stack traces look like the following:

So I open up my Rakefile and make these lines

require 'rake'
require 'rake/testtask'
require 'rake/rdoctask'

to

require 'rake'
require 'rake/testtask'
require 'rdoc/task'

Supposedly, I should also add gem “rdoc” to my Gemfile:

$ cat /usr/lib/ruby/gems/1.8/gems/jquery-rails-1.0.9/Gemfile
source :gemcutter

Specify your gem's dependencies in jquery-rails.gemspec


gemspec

Rails is already being pulled in through gemspec
gem "rails", :git => "git://github.com/rails/rails.git"


gem "rack", :git => "git://github.com/rack/rack.git"
gem "sprockets", :git => "git://github.com/sstephenson/sprockets.git"
gem "i18n", "0.6.0beta1"

But I’m unable to overwrite the write permission:

I don’t understand what’s going on. Deleting gemfile.lock wouldn’t help.

Someone on the web suggested adding rdoc/ to my .gitignore, too.

Anyway, I just go ahead and install the daemons:

$ sudo gem install daemons
Fetching: daemons-1.1.4.gem (100%)
Successfully installed daemons-1.1.4
1 gem installed
Installing ri documentation for daemons-1.1.4...
Installing RDoc documentation for daemons-1.1.4...

So what are these daemons, after all?

Daemons provides an easy way to wrap existing ruby scripts (for example, a self-written server) to be run as a daemon and to be controlled by simple start/stop/restart commands. You can also call blocks as daemons and control them from the parent or just daemonize the current process. Besides this basic functionality, daemons offers many advanced features like exception backtracing and logging (in case your ruby script crashes) and monitoring and automatic restarting of your processes if they crash.  – RubyGems.org

Finally, I’m able to successfully start the web server:

/usr/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:29:in `gem_original_require': no such file to load -- nokogiri (MissingSourceFile)

Nokogiri parses and searches XML/HTML very quickly, and also provides CSS3 selector support and XPath support for document searching.

I installed the nokogiri parser before the system upgrade, but it might’ve gotten lost or updated during the upgrade. So I have to install nokogiri again on 11.4:

~/branch/build-service/src/webui> sudo gem install nokogiri
Fetching: nokogiri-1.5.0.gem (100%)

I remember seeing this problem before. The solution is to simply install the dependencies first:

$ sudo zypper install libxml2

'libxml2' is already installed.
No update candidate for 'libxml2-2.7.8-16.17.1.i586'. The highest available version is already installed.

Nothing to do.

The trick is to install libxml-devel package instead:

$ sudo zypper install libxml2-devel

The following NEW packages are going to be installed:

It looks like nokogiri needs both of these two dependencies resolved first:

☑ libxml/parser.h
☑ libxslt/xslt.h

Thus, the requirements for installing nokogiri are:

✓ ruby 1.8 or 1.9
✓ libxml2
✓ libxml2-dev
✓ libxslt
✓ libxslt-dev

Then, I’m able to install nokogiri:

$ sudo gem install nokogiri

• - – - – - -

• You only download the packages that need to be upgraded, saving a lot of bandwidth.
• During the upgrade you can still use your system (although this is not recommended); the only downtime will be the reboot after the upgrade.
• You do not have to write an ISO image to a DVD. You could also boot from 1) the Internet; or 2) a USB key, and install the rest from the Internet

The disadvantages:

• If, for any reason, the upgrade is interrupted (e.g., power outages, network disconnect) and the process can’t continue, you could be left with a broken system (that depends on where the process stopped, of course).
• If you have multiple systems to upgrade, you consume bandwidth each time, which is less efficient than downloading an ISO image.

The upgrade can be done on the command line or via the YaST module Wagon (if you are on an OpenSUSE desktop). Since the Wagon method is less tested than the command line update, we will use the command line method here for both servers and desktops.

1. Install the latest updates

Before doing the distribution upgrade, install the latest updates for OpenSUSE 11.3. Open a terminal and run

$ sudo zypper repos --uri

to check what repositories are used and enabled on the system.

Make sure that the line that contains http://download.opensuse.org/update/11.3/ in the URI column reads “Yes” in the “Enabled” column:

#  | Alias                               | Name                                | Enabled | Refresh | URI

If the line reads “No” in the “Enabled” column, enable the repository as follows:

$ sudo zypper modifyrepo --enable #Alias_name

If there’s no repository with the URI http://download.opensuse.org/update/11.3/, then add the repository:

$ sudo zypper addrepo --check --name 'openSUSE-11.3-Update' http://download.opensuse.org/update/11.3/ repo-update

Now, install the latest updates:

$ sudo zypper refresh

Search for updated openSUSE 11.4 compatible third-party repositories that you used before and add them.

$ sudo zypper addrepo --name <name> <url> <alias>

For example, if you used the VirtualBox repository in 11.3, you can enable the VirtualBox repository in 11.4 like this:

$ sudo zypper addrepo --name "VirtualBox for openSUSE 11.4" http://download.virtualbox.org/virtualbox/rpm/opensuse/11.4 virtualbox-11.4

(Use values for Name and Alias that are not in use yet.) Be aware that using third-party repositories could increase the chances that the upgrade will not complete correctly.

Now, run the full distribution upgrade:

$ sudo zypper ref

This retrieves the metadata for the 11.4 repositories (i.e., openSUSE-11.4 Non-OSS, openSUSE-11.4 OSS, and openSUSE-11.4 Updates), and builds up caches for those repositories.

Then, do

On the other hand, installing the Broadcom wireless driver for different Linux distros is a great learning experience.

Previously, I talked about how to activate the Broadcom STA wireless driver in Fedora 14. It turns out the activation is slightly different in openSUSE.

The following works on openSUSE 11.3, 11.4, Mint 10 Julia, Ubuntu 10.x, Kubuntu 10.x, and LMDE.

To make Wi-Fi work in openSUSE 11.4, first download the tarball containing Broadcom’s IEEE 802.11a/b/g/n hybrid Linux device driver from http://www.broadcom.com/support/802.11/linux_sta.php

The cards with the following PCI Device IDs are supported with this driver.
Both Broadcom and and Dell product names are described.  Cards not listed here
may also work.

 	    BRCM		    PCI	PCI		  Dell
	    Product Name	  Vendor ID	Device ID	Product ID
          -------------	 ----------	---------   -----------
          4311 2.4 Ghz	    0x14e4	0x4311  	Dell 1390

          4322 2.4 Ghz      0x14e4 	0x432c
          4322 5 Ghz        0x14e4 	0x432d
          43224 Dualband    0x14e4	0x4353  	Dell 1520
          43225 2.4 Ghz     0x14e4	0x4357
          43227 2.4 Ghz     0x14e4      0x4358
          43228 Dualband    0x14e4      0x4359          Dell 1530

To find the Device ID's of Broadcom cards on your machines do:

lspci -n | grep 14e4

Untar the package:

$ tar -xvf hybrid-portsrc_x86_32-v5_100_82_38.tar.gz 

And build this driver from source:

$ make
KBUILD_NOPEDANTIC=1 make -C /lib/modules/`uname -r`/build M=`pwd`
make: *** /lib/modules/2.6.37.6-0.7-desktop/build: No such file or directory.  Stop.
make: *** [all] Error 2

Looks like you yet need to install the proper packages, which will create /lib/modules/”release”/build on your system. Take a quick check on what kernel packages you have:

$ rpm -qva | grep kernel
kernel-desktop-2.6.37.6-0.7.1.i586
kernel-default-2.6.37.6-0.7.1.i586

So, just install ‘kernel-devel’ (Development Package for building kernel modules to match the kernel):

$ sudo zypper install kernel-devel

There is still an error building the driver. The expected wl.ko file wasn’t generated.

It turns out there is a compilation problem with kernel versions > 2.6.37. The kernel I have falls right into that range:

$ uname -a
Linux opensuse 2.6.37.6-0.7-desktop #1 SMP PREEMPT 2011-07-21 02:17:24 +0200 i686 i686 i386 GNU/Linux

We need to apply a patch to fix the ‘init_MUTEX’ compile problem on newer (> 2.6.37) kernels.

At the top level of the driver source folder  (where ”ls” should show at least src, lib, Makefile), create a file which I named “patch.” Fill in the following lines:

Now, let’s do a fresh install of the wl driver, since the system was just upgraded live to openSUSE 11.4 and no previous version of the wl driver has been running.

First, check if there’s any other driver for Broadcom wireless device on the system:

$ lsmod  | grep "b43\|ssb\|wl"
$ [blank]

Looks good. If any of these are installed, remove them:

# rmmod b43

rmmod ssb
rmmod wl

And blacklist these drivers and prevent them from loading in the future:

# echo "blacklist ssb" >> /etc/modprobe.d/blacklist.conf

echo "blacklist b43" >> /etc/modprobe.d/blacklist.conf

At root,

# cp wl.ko /lib/modules/`uname -r’/kernel/net/wireless/

insmod wl.ko


insmod: can't read 'wl.ko': No such file or directory

You could skip insmod wl.ko if it doesn’t work.

Make sure you’re root “su -“. Otherwise, you’d get this:

$ sudo insmod wl.ko
root's password:
sudo: insmod: command not found

Proceed to

# modprobe lib80211

depmod -a
modprobe wl

Now, check your Network Manager, and you should see wireless networks immediately.

In openSUSE, the module will be loaded on boot. In Mint/Ubuntu/Kubuntu/LMDE, users will need to add it manually in /etc/modules file.

The biggest change was adding embedded collapsible buttons.

I tried serializing Files and loading the list alphabetically sorted, like this:

<script type="text/javascript">

 // build up a javascript array from the file list
 var filelist = [
<% @files.each do |file|
 fl = file.submit if file.has_element? :submit
 fl = file.action if file.has_element? :action
 pkg = ""
 if fl.has_element?(:pkg)
 pkg = elide(ae.pkg.package, 20)
 if fl.pkg.has_attribute?(:package)
 pkg += "/ #{elide(fl.target.package, 12)}"
 end
 end
 -%>
 {"name": "<%= elide(file.name, 12) %>", "pkg": "<%= pkg %>"
<% end -%>
 ];

 // renders the file list
 function render_list(criteria) {
 console.debug("rendering list, ordered by: " + criteria);
 var list = $("#file_list");
 $(list).empty();

 var files = filelist.sort(function(a, b) {
 switch (criteria) {
 case 'name':
 return a.name > b.name;
 }
 });

 list.append("<li data-role=\"list-divider\">Files contained in this package</li>");
 $.each(files, function() {
 list.append("<a href='<%= url_for :project => @project, :package => @package, :action => :files %>/" + this.name + "'></a>");
 });
 }

 // initial render after page load
$(document).ready(function(){
 render_list("name");
});

</script>

In the mobile view, I would like to have the Files loaded as a pre-sorted list:

<% @files.each do |file| %>
 <div data-role="collapsible" data-collapsed="true">
 <h3><%= h file %> </h3>

 <ul data-role=”listview”>
 <% if @package.linkinfo %>
 <% if @expand && @expand.to_s == "1" %>
 <%= link_to '(show unmerged sources)', :project => @project, :package => @package, :action => :files, :rev => params[:rev], :expand => "0" %>
 <% else %>
 <%= link_to '(show merged sources derived from linked package)', :project => @project, :package => @package, :action => :files, :rev => params[:rev], :expand => "1" %>
 <% end %>
 <% end %>
 </ul>
</div>
<% end %>

But when I compile, I get this error:

[FATAL|# 8894] ActionView::TemplateError (You have a nil object when you didn't expect it!

In desktop views, Files are implemented as a table and sorted with jquery.tablesorter.js. In mobile view, Files would have to be converted to an Array. I can’t quite tell what went wrong here, or how else to do it.

This is the ideal view I would like to have:

I re-examined the code in the prototype, and realized these sorting buttons were laid out as control group buttons as follows:

<div data-role="controlgroup" data-type="horizontal">
 <a href="#" onclick="render_list('date'); $('#request_list').listview('refresh'); return false" data-role="button" data-theme="b">Date</a>
 <a href="#" onclick="render_list('requester'); $('#request_list').listview('refresh'); return false" data-role="button">Requester</a>
 <a href="#" onclick="render_list('target'); $('#request_list').listview('refresh'); return false" data-role="button">Target</a>
 <a href="#" onclick="render_list('state'); $('#request_list').listview('refresh'); return false" data-role="button">State</a>
</div>

After some web research, I learned that control group buttons might not provide what I wanted. More than one button in a control group can be active at a time. I also looked at the demos and examples on jQuery Mobile website. For control group buttons, there doesn’t seem to be any highlighting for the selected button. There is a millisecond of color change when the button is being clicked. But after the clicking is finished, the buttons return to their default data-theme. 

One thing I could think of to make this highlighting happen for control group buttons is to dynamically change the data-theme for each selected button, but it seems to be an overkill for this tiny issue.

On the other hand, radio buttons seem to perform exactly the way I wanted. With radio buttons, the highlighting comes automatically once the button is selected (the newly selected button is added to the selector class, as the previously selected one is removed from there).

A second option to fix the button highlighting would be to change the control group buttons to radio buttons. A group of radio buttons always have at least one option selected, and that selected button is always highlighted. This would work perfectly on the Request view page, as requests would always display sorted by date.

(Check out jQuery Mobile documentation on radio buttons)

Switching the UI from control group buttons to radio buttons was easy:

<div data-role="fieldcontain">
 <fieldset data-role="controlgroup" data-type="horizontal" >
 <input type="radio" name="radio-choice-1" id="radio-choice-1" value="date" checked="checked" />
 <label for="radio-choice-1">Date</label>

 <input type="radio" name="radio-choice-1" id="radio-choice-2" value="requester" />
 <label for="radio-choice-2">Requester</label>

 <input type="radio" name="radio-choice-1" id="radio-choice-3" value="target" />
 <label for="radio-choice-3">Target</label>

 <input type="radio" name="radio-choice-1" id="radio-choice-4" value="state" />
 <label for="radio-choice-4">State</label>
 </fieldset>
</div>

But binding an onclick event to the radio buttons took a bit effort. The trick was to use “change” instead of “click.”

 // initial render after page load
$(document).ready(function(){
 render_list("date");
 $("input[type='radio']").bind("change", function(){
 var selection=$(this).val();
 //alert("Criterion changed. Selected: "+selection);
 render_list(selection); 
 $('#request_list').listview('refresh');
 })
});

Now the buttons are correctly implemented. The final Requests views look like the following:

• - – - – - -

1. Request state has been added to each request;
2. Sorting functions have been implemented for Requests;
3. A search filter has been added to the Request page.

Now, when the user logs into the list of requests, the user will not only be able to see the state of each request, but also sort requests based on 4 criteria:

• request date
• requester’s name
• target project/package
• request state

The user can also filter requests by typing in a keyword:

These new features have been tested in my desktop browsers and on my Android device, and they seem to be working fine.

Please feel free to check out the new features as soon as they are merged to the master. Feedback and comments are always welcome & appreciated.
