Merge lp:~leonardr/launchpadlib/multiversion into lp:launchpadlib

[Leonard Richardson]

[Leonard Richardson (leonardr)]

This branch changes launchpadlib to take advantage of lazr.restful's 'version' constructor argument. Instead of a service root of http://api.launchpad.net/beta/, you now use a service root of http://api.launchpad.net/ and a version of "beta". This makes it much easier to specify which version of a web service you want to use.

This branch also changes the default version of the web service to 'devel'. Here is the plan (not yet ratified by distro developers):

1. We get a launchpadlib release based on this branch into Lucid before the feature freeze. At this point anyone who writes launchpadlib scripts with beta versions of Lucid will be using the unstable 'devel' version of the web service.

2. Before Lucid is released, we make some changes to the Launchpad web service and freeze a '1.0' release.

3. We make a small launchpadlib release that does nothing but change the default web service version to '1.0'. Anyone who writes launchpadlib scripts with the released
version of Lucid will be using the frozen '1.0' version of the web service.

This is flacoste's plan; I would prefer to change the default web service version to '1.0' in this branch, and not mess with Lucid any more after this.

Either way, by releasing a '1.0' version of the web service and tying it to Lucid, we will be able to retire the 'beta' version when we retire Karmic. If we don't get this done, we won't be able to retire the 'beta' version until we retire Lucid.

s/lazr.restful/lazr.restfulclient/ in the above.

The default for production should still be beta, at least until this code is
deployed to production. Otherwise, anybody will get breakage when they try
launchpadlib on lpnet.

"The default for production should still be beta, at least until this code is
deployed to production. Otherwise, anybody will get breakage when they try
launchpadlib on lpnet."

Then maybe the launchpadlib default should continue to be "beta", and once we're ready, we can change it to "1.0". Rather than changing it to "devel" and then to "1.0".

It's really something to discuss with the Ubuntu release team. Each scenario
has different trade-off in expectations management.

On further reflection I believe this point is moot. Right now, the "devel" version isn't deployed any more than the "1.0" version is. https://edge.launchpad.net/api/devel leads to a 404. If we want Lucid developers to be able to use launchpadlib, we have to give them "beta" by default until "1.0" and "devel" are deployed. At that point we might as well give them "1.0".
