Re: Good News: China Music Scope for 13.04 with new APIs works well

 

Hi Didier,
     Because API changes have been postponed, we recreated a series of unity-china-music-scope (1.0 ) for 13.04 at
https://launchpad.net/unity-china-music-scope . Please help us to check it, thanks in advance :)
 
Regards,
Jonas

All,

Unfortunately, I had some not so good news. This morning a decision had been made to postpone API changes (and all the changes listed in the FFe) to next Ubuntu release ("S") and
keep the existing API/infrastructure in 13.04 (so, it's the same as in 12.10); the main reason for this decision was an overall agreement about user experience being not good enough with current set of changes.

For your project that means that recent changes that you made for the new API should be reverted for your scope to land in 13.04; it needs to work with the official Unity stack currently in Raring. I advise you to keep a copy of these changes around in a separate branch, as they will be useful for S. Please contact Didier Roche about anything related to packaging and getting your scope into 13.04.

I'm sorry to bring these news to you, but in the end we all believe in delivering the best UX, and this sometimes means delaying things until we feel they are fully ready. Thank you for all the hard work and effort you put into china-music-scope so far!

Kind Regards,
Pawel

Hi Pawel,
    We have done all steps you advised again. Now unity-china-music-scope with new APIs  can work well. Attachment is the screenshot.
    However,  we still have some small issues on packaging and are trying to solve it. BTW, unity-china-music-scope-0.9.0 for 12.04 has already been on UbuntuKylin PPA (https://launchpad.net/~ubuntukylin-members/+archive/ubuntukylin/+packages). But only i386.deb was built now. Version for amd64 hasn't been built for 2 hours...

Hi Pawel,
    Firstly, we have update the code to new APIs ( using DeprecatedScope* class), you can find it at lp:unity-china-music-scope
    Then we do as following:apt-get dist-upgrade
- add ppa:ubuntu-unity/experimental-prevalidation
- apt-get dist-upgrade
- run libunity-tool -g
  here is the screenshot:


    Nothing is shown in Dash. And the left is libunity-tool with musicstore-scope which is always timeout, while the right hand is libunity-tool with china-music-scope in which correct results are returned.
    Does it mean that our scope is OK already? Shall we ask for FFe or report on FFe bug you have mentioned: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1154229 ?

Best regards,
Jonas

Hello,

You should be using  the ppa listed in the FFe bug I mentioned earlier, which at the moment is empty, in which case you can use ppa:ubuntu-unity/experimental-prevalidation. You need to apt-get dist-upgrade your Ubuntu after enabling it; this will replace your entire Unity stack (Dash, libunity, lenses etc.). I don't recommend using this ppa on a production machine, you may want to use a virtualbox to test it out as there are still bugs.

Let me know if you have any issues,

Best Regards,
Pawel

Hi Pawel,
    Addition: after we downloaded the newest iso image (May 25) and installed it, we replaced the libunity to libunity-7.0 and we found Dash works abnormaly.
 
Cheers,

Hi guys,

How is the migration to the new API going, any problems with it? I haven't got any questions so far, can we assume it's going smooth? Please keep in mind the weekend is coming, I'll be occasionally checking my email, but if anything urgent pops up, there may be little/no time for me to react, or we may need help from somebody else (if it's beyond my expertise) and this can be an issue. Please let me know if you need anything as soon as possible.

Kind Regards,
Pawel

Hi Pawel,
  We will catch up with changes of new API and make sure the scope can work in 13.04.

Weihua, all,

As you might or might now know, the API changes we planned for 13.04 didn't land on time. We're currently working on finishing the transition to the new API and finishing/polishing some areas (in particular the new Home Scope); there is a Feature Freeze Exception bug filed to get the new stack landed if FFE is approved. In other words, you should port your scope to the new API and have a branch ready for merging when all the base infrastructure we're working on lands, otherwise your scope won't work in 13.04.

The latest API is available in libunity-7.0 branch of libunity, there is a number of scopes ported to it already, plus Unity Dash branch. There are two options for you when porting:
- base your scope on DeprecatedScope* class, which requires only minimal changes to your code;
- inherit your scope on AbstractScope; this requires more changes as you need to implement a number of abstract methods; this is the recommended way.

Both options impose no real changes to "business logic" of scopes. If you choose option #1, you should be able to migrate your code in a matter of few hours tops.

Here is the FFe bug I mentioned:
https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1154229
There you'll find all relevant branches, information about ppa etc. Take a look at any of the scopes linked there (for default Ubuntu scopes such as applications, files etc. you need to be looking at -libunity7-compatible branches). 100 scopes such as "wikipedia" and other listed there are using the AbstractScope approach, while our default scopes use DeprecatedScope API.

Kind Regards,
Pawel

Dear Pawel,
    As you wrote in last email:

Until all these changes land in Ubuntu 13.04 repositories (which should happen in ~2-3 weeks), the only way to test a scope against new API is:
- install latest Dee from trunk and libunity-7 branch (don't install system-wide as this would break your current Unity environment; install them in a dedicated subdirectory).
- compile your scope against libunity-7 and run it manually from a terminal.
- test search queries with 'tool/libunity-tool -g' from libunity-7 branch.


    We begin to port unity-china-music-scope to new API. Before I start my work I have some questions:
 1. how to install  latest Dee and libunity-7 branch in a dedicated subdirectory? Do you mean old version and new version can exist together?
 2. how to test search queries with 'tool/libunity-tool -g' from libunity-7 branch?
   
Cheers,
Weihua
