Description

The package "libmysqlclient-dev" is a virtual package that doesn't show up in apt-cache policy, but specifying it for installation with apt-get install will auto-resolve dependencies:

lenny1test:~
$ apt-cache policy libmysqlclient-dev
libmysqlclient-dev:
  Installed: (none)
  Candidate: (none)
  Version table:
lenny1test:~
$ apt-cache show libmysqlclient-dev
lenny1test:~
$ echo $?
0
lenny1test:~
$ sudo apt-get install libmysqlclient-dev
Reading package lists... Done

aptitude will reveal that the package is virtual and list the package name that provides the actual package

$ aptitude show libmysqlclient-dev
No current or candidate version found for libmysqlclient-dev
Package: libmysqlclient-dev

- should raise an exception if aptitude show fails
- should not raise an exception if aptitude show succeeds
- should raise an exception if aptitude show does not return a candidate version

This is a great patch, it will make man people's lives easier. A few notes:

  • it's best not to use predicate method names (i.e., ending with a '?') for methods that mutate state, as in most cases these methods don't modify state in ruby so it's counter to expectations to do that.
  • I know a lot of our existing tests are really bad offenders here, but you don't need to mock out strings, you can just use strings. For example, since ShellOut#stdout returns a string, you don't need to stub #each_line on it, you can just return a string that matches the expected output of that command and not worry about how the underlying code processes the string.

Those are just nitpicks though, this patch is solid and a really sweet improvement to the provider. Thanks!

This patch fixes what it supposed to fix, but broke normal apt functionalities, so I will reopen this ticket. The code has been reverted in the master branch, for now.

I found the following problems with the patch, please take a look and fix so that we can merge the patch back to master.

Problem 1:

The code tries to read the "Depends:" line and call check_package_state recursively for the whole "Depends:" line, which causes syntax error. For example:

aptitude show sudo

has the following line:

Depends: libc6 (>= 2.8), libpam0g (>= 0.99.7.1), libpam-modules

And then it tries to do:

aptitude show libc6 (>= 2.8), libpam0g (>= 0.99.7.1), libpam-module

which gets syntax error near unexpected token `('

Problem 2:

After a rough look, the logic may not be completely right as well. Still use the sudo package as example, on a box sudo has been installed, running aptitude show sudo returns the following:

Package: sudo
State: installed
Automatically installed: no
Version: 1.7.2p1-1ubuntu5
Priority: important
Section: admin
Maintainer: Ubuntu Core Developers <ubuntu-devel-discuss@lists.ubuntu.com>
Uncompressed Size: 602k
Depends: libc6 (>= 2.8), libpam0g (>= 0.99.7.1), libpam-modules
Conflicts: sudo-ldap
Replaces: sudo-ldap
Provided by: sudo-ldap
Description: Provide limited super user privileges to specific users
Sudo is a program designed to allow a sysadmin to give limited root privileges
to users and log root activity. The basic philosophy is to give as few
privileges as possible but still allow people to get their work done.

This version is built with minimal shared library dependencies, use the
sudo-ldap package instead if you need LDAP support.

Say we have a recipe like this:

package "sudo" do
action :install
end

And then the current code tries to call check_package_state recursively for "sudo-ldap" after doing so for "sudo", which is not necessary/correct in this case since sudo is installed and it should really not trying to see if sudo-ldap is installed or not.

Testing prerelease Gem Chef 0.10.4-rc.2, I ran into issues installing the imagemagick package.

I think it's just some bad string parsing, note the comma:

I tried the latest Gem with imagemagick on a clean Ubuntu 10.04. Now it thinks it's installed, when Aptitude reports it isn't. Not sure why imagemagick is being so difficult.

Description: image manipulation programs
 ImageMagick is a software suite to create, edit, and compose bitmap images. It
 can read, convert and write images in a variety of formats (over 100) including
 DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF.
 Use ImageMagick to translate, flip, mirror, rotate, scale, shear and transform
 images, adjust image colors, apply various special effects, or draw text,
 lines, polygons, ellipses and B?zier curves. All manipulations can be achieved
 through shell commands as well as through an X11 graphical interface (display).

Description: high-quality block-sorting file compressor library - runtime
 This package contains libbzip2 which is used by the bzip2 compressor. 
 
 bzip2 is a freely available, patent free, high-quality data compressor. It
 typically compresses files to within 10% to 15% of the best available
 techniques, whilst being around twice as fast at compression and six times
 faster at decompression. 
 
 bzip2 compresses files using the Burrows-Wheeler block-sorting text compression
 algorithm, and Huffman coding. Compression is generally considerably better
 than that achieved by more conventional LZ77/LZ78-based compressors, and
 approaches the performance of the PPM family of statistical compressors. 
 
 The archive file format of bzip2 (.bz2) is incompatible with that of its
 predecessor, bzip (.bz).

Glenn Pratt added a comment - I tried the latest Gem with imagemagick on a clean Ubuntu 10.04. Now it thinks it's installed, when Aptitude reports it isn't. Not sure why imagemagick is being so difficult.

We shouldn't even be touching imagemagick with this code. That isn't a virtual package. I'm working on some refactoring.

commit 4c9b9e60c93491f68abe15f49996ab6db4b88b60

If a virtual package is provided by a single real package, we ask apt to install the virtual package and it in turn installs the real package. The same goes for removal.
If a virtual package is provided by multiple real package, we throw an exception asking the user to be more explicit, which is what apt does.

aptitude is slow.

apt-cache policy doesn't differentiate between virtual packages with one provider and those with more than one.

refactored to use 'apt-cache policy' again. now we parse the output of 'apt-cache showpkg' if we think we're a virtual package to verify that there is a provider via 'Reverse Provides:'
