Sync libchewing 0.3.5-2 (main) from Debian unstable (main)

I am one of the maintainer of libchewing, and I also help to build debian package for 0.3.5.

- The benefit of upgrading is avoiding crashing issue in end user.
- The downside is that scim-chewing locks itself into 0.3.4 excluding. It needs patch if libchewing is upgraded to 0.3.5.

The following crash issues are fixed in libchewing 0.3.5. Except 71a55c0 and 35881e, other issue might be triggered by user can cause libchewing crash.

71a55c0 Prevent unaligned memory access
35881e Reduce maxChiSymbolLen to 39 to avoid overflow
8fb6653 Do not store user phrase when its length is 1
16d378d Check chiSymbolBufLen in chewing_handle_Numlock()
b53c694 Set isSymbol to 0 in SetChoiceInfo
1afcc26 Fix 'j', 'k' in select mode cannot handle symbol selecting
b262b06 Do not call GetCharNext() when GetCharFirst() fails

I built libchewing 0.3.5-2 with i386/amd64 pbuilder, and they all built successfully. . I also setup a daily build [1] and use develop snapshot every day without any issue.

Hi. Are you saying that this new version of libchewing doesn't work right with the version of scim-chewing in Saucy?

Especially since Ubuntu has now passed Feature Freeze, we don't want to break things that work. Also, new releases that aren't simply bugfix releases should get approval by the Ubuntu Release team first. In the future, you can use the -e option when using requestsync.

Hi Chen,

Is there any existing patch for scim-chewing around? If so could you point it to us to so that we can better evaluate this update.

Thanks.

Hi,

The patch is in [1]. Just change the version comparison from "=" to ">=" so that scim-chewing does not need particular version of libchewing.

Hey Aron, did you see the new comment there? Could you have another look and tell us if that should be uploaded for saucy?

Hi,

Please also patch the attachment for upstream issue 75 [1] when upgrading to 0.3.5-2. See debian issue 722971 [2] for more information.

As of my testing, this update is safe and desirable, updating it to FFe.

Here is the debdiff for scim-chewing, I don't have PPU for the package and need someone to sponsor it.

This bug was fixed in the package scim-chewing - 0.3.4-4ubuntu3

---------------
scim-chewing (0.3.4-4ubuntu3) saucy; urgency=low

  * Fix checking of higher version of libchewing (LP: #1220224).

AFAIK this got deferred to T-cycle because the changes are large for this late stage in Saucy
