Merge lp:~marcelstimberg/ubuntu/natty/epdfview/fix-for-783109 into lp:ubuntu/natty/epdfview

[Marcel Stimberg]

A branch with backported changes from rev 357 and rev 359, additional the "cosmetic" patch from rev 336 was also necessary in order for the other two patches to apply cleanly. This fixes crashes on many PDF documents, due to API changes in libpoppler.

[Chris Coulson (chrisccoulson)]

Thanks for your work. However, it seems like you included a few unnecessary files in your patch:

- epdview/THANKS.orig
- epdfview/configure.ac.orig
- epdfview/src/IDocument.cxx.orig
- epdfview/src/PDFDocument.cxx.orig

Also, the diff is huge because the branch is normally pushed with the patches applied, whereas your merge proposal has none applied

review: Needs Fixing

[Marcel Stimberg (marcelstimberg)]

Thanks for taking a look at the branch. I removed the unnecessary files and left all patches applied for consistency (although I was under the impression that bzr branches/source packages should not have patches applied...). The diff is now to a reasonable size :-) So please, take a look again.

[Daniel Holbach (dholbach)]

This looks much better. Can you also submit a merge proposal for oneiric, so we can get it in there first (and follow https://wiki.ubuntu.com/SRU)? Thanks a lot in advance.

> This looks much better. Can you also submit a merge proposal for oneiric, so we can get it in there first (and follow https://wiki.ubuntu.com/SRU)?
Thanks. Since I created this branch, Debian packaged a new upstream
version – I'll therefore submit a sync request for Oneiric instead. At
the first sight, there's no need for Ubuntu-specific patches for the
new version anymore, since these were all backported upstream changes.
But I'll check this more thoroughly later tonight.

[Marcel Stimberg (marcelstimberg)]

epdfview 0.8.1 has been synced to Oneiric, so all that remains is the SRU for Natty.

[Stefano Rivera (stefanor)]

Looks good, would you mind using the version number 0.1.7-5ubuntu1.1?

24. By Marcel Stimberg on 2011-06-19

change version number to ubuntu1.1 instead of ubuntu2

[Marcel Stimberg (marcelstimberg)]

> Looks good, would you mind using the version number 0.1.7-5ubuntu1.1?
No problem, I updated the numbering.

[Stefano Rivera (stefanor)]

Thanks, uploaded to natty-proposed, pending SRU team review
