Installing the PEAR/PECL uploadprogress extension for Drupal 7

Trying out the latest development snapshot of Drupal 7, I noticed it supports the uploadprogress PEAR/PECL extension, which apparently lets you see the actual progress (with some kind of Ajaxy widget) while uploading files. Sounds cool to me.

First, I installed PEAR (on my Ubuntu testing server):

$ sudo aptitude install php-pear

and then tried to use PEAR to install uploadprogress:

$ sudo pear install pecl/uploadprogress
downloading uploadprogress-1.0.1.tgz ...
Starting to download uploadprogress-1.0.1.tgz (8,536 bytes)
.....done: 8,536 bytes
4 source files, building
running: phpize
sh: phpize: not found
ERROR: `phpize' failed

PHPize? What’s that? There’s no phpize package; aptitude search phpize gives nothing.

A bit of digging and I found that PHPize is part of the php5-dev package! After installing that, pecl can install a module just fine:

Solution

$ sudo apt-get install php5-dev
$ sudo pear install pecl/uploadprogress

After lots of output, PEAR left a final clue:

configuration option "php_ini" is not set to php.ini location
You should add "extension=uploadprogress.so" to php.ini

So I created /etc/php/conf.d/uploadprogress.ini, containing just this line:

extension=uploadprogress.so

I restarted Apache and now Drupal 7 reports “UPLOAD PROGRESS: Enabled”. Now to try it out….!

Installing the mysql Ruby gem

While trying to install this gem on Ubuntu 8.04.3 (Hardy) to run a rails app (Redmine), I encountered the following error:

$ sudo gem install mysql
Building native extensions. This could take a while...
ERROR: Error installing mysql:
ERROR: Failed to build gem native extension.

/usr/bin/ruby1.8 extconf.rb
extconf.rb:1:in `require': no such file to load -- mkmf (LoadError)
from extconf.rb:1

There are a bunch of common errors when installing the mysql gem, so Googling for the solution wasn’t instant. Luckily I found this post which showed the missing package: ruby1.8-dev.

Solution

sudo apt-get install ruby1.8-dev

and the MySQL gem installed fine.

gem won’t install Ruby gems on VPS…

Having trouble installing Ruby gems on your VPS? Gem was hanging on my Slicehost slice (running Ubuntu Hardy with 256MB of RAM) at “Bulk updating [...]“:

$ gem update
Updating installed gems...
Bulk updating Gem source index for: http://gems.rubyforge.org

It was also gobbling up CPU and memory.

Why does gem hang?

The distro package for Gem is very old, and this old version uses a lot of memory, causing lots of disk thrashing. Since hard disks are, ahem, a bit slower than RAM, this increases gem’s run time by probably a few orders of magnitude.

Solution

Update gem manually:

$ wget http://rubyforge.org/frs/download.php/57642/rubygems-update-1.3.4.gem
$ sudo gem install rubygems-update-1.3.4.gem
$ sudo /var/lib/gems/1.8/bin/update_rubygems
Installing RubyGems 1.3.4
Installing RubyGems
Installing gem executable
Removing old source_cache files
Removing old RubyGems RDoc and ri
Installing rubygems-1.3.4 ri into /usr/lib/ruby/gems/1.8/doc/rubygems-1.3.4/ri
Installing rubygems-1.3.4 rdoc into /usr/lib/ruby/gems/1.8/doc/rubygems-1.3.4/rdoc

RubyGems installed the following executables:
/usr/bin/gem1.8

Looks like everything’s OK, but gem didn’t work anymore:

$ sudo gem install haml
/usr/bin/gem:10: undefined method `manage_gems' for Gem:Module (NoMethodError)

What gives? Notice the path, /usr/bin/gem. Is that still the old version?

$ ls -lah /usr/bin/gem*
-rwxr-xr-x 1 root root 701 Nov 19 2007 /usr/bin/gem
-rwxr-xr-x 1 root root 545 Jul 28 00:15 /usr/bin/gem1.8

Yes. This is what we get for upgrading gem without using Ubuntu’s package system. Well, in for a penny, in for a pound:

sudo mv /usr/bin/gem1.8 /usr/bin/gem

Done. Now to install Haml and Sass….
