[SRU] Wrong input results

[Mathieu Bridon]

[Impact]

Ubuntu Trusty and Utopic are currently shipping some older versions of libcangjie, which have some known issues.

Those are fixed in libcangjie 1.3, which is already in Vivid.

Trusty currently ships libcangjie 1.0, and Utopic has 1.1.

Moving from 1.0 to 1.3 implies no API/ABI break. (I even checked that with abidiff, just to be sure)

The full release notes are available at this link:
    https://github.com/Cangjians/libcangjie/releases

As one of the upstream developers for libcangjie, I'd prefer you just updated to the latest upstream release in both Trusty and Utopic, but I can understand this might not be the proper process in Ubuntu, so I'll be more than happy to work with you to review differences, help backport patches, or anything else which could help.

At the very least, user experience would be vastly improved by just applying the following patches to the Ubuntu packages, both in Trusty and Utopic:

* https://github.com/Cangjians/libcangjie/commit/5e2abdb2f9dd122efd543307b7a1e2449943ca7d.patch
* https://github.com/Cangjians/libcangjie/commit/f363e39fdb738d4d393250db46e8db5c90d28132.patch

These are all **data** fixes, no code changes. Getting this data fixed in Ubuntu packages means that users will get the results they are expecting when typing Chinese with IBus Cangjie.

These data fixes are important for Hong Kong users, who in majority use a Cangjie input method. Most of them tend to run the latest LTS, which is why I'd really like to have these fixes pushed all the way back to Trusty.

The rest of the changes between 1.0 and 1.3 are minor and don't have any impact for users, so I won't be mad if you chose not to get them. :)

[Test Case]

1. install the package, as well as ibus-cangjie
2. configure the ibus-cangjie input method
3. type some cangjie codes, for example:
 * "raiu" gives no result with the current Trusty/Utopic package, but it should return 嘅 with the above patches
 * "okrx" returns 佑 with the current Trusty/Utopic package, but it should return 知 with the above patches

[Regression Potential]

I can't think of any, especially if you only apply the data fixes I listed above.

Also, note that this is quite a leaf-ish package: as far as I know, only pycangjie and ibus-cangjie depend on it. (for which I am also upstream)

Finally, this is quite a niche package: it is only useful to desktop users who need to type Chinese with a Cangjie input method (that's mostly Hong Kong, and some in Taiwan) in IBus.

So all in all, this should be a very safe update.

Status changed to 'Confirmed' because the bug affects multiple users.

[Didier Roche-Tolomelli (didrocks)]

Note that the packaging has some Priority changes + an additional Conflicts. Both shouldn't create any issue and so, I kept them to stay aligned with latest debian's packaging.
