Read doesn't work with gnome-python-evince-2.30.0

[alsroot]

Having:
gnome-python-evince-2.30.0-1mdv2010.1
libevince2-2.30.0-1mdv2010.1
evince-2.30.0-1mdv2010.1

Read-78 (looks like older versions as well since they use the same API) doesn't work. It can't find at least:

• evince.View.set_screen_dpi
• evince.factory_get_document (should be evince.document_factory_get_document)
• evince.View.props.zoom

I'm setting Severity to Critical since Read-78(and looks like older versions) can't work in recent distributions.

This simply prevents Read from working on Fedora 13 - and hence in SoaS - and will presumably cause it to be removed, since it got noticed past final freeze.

Ouch - it looks like a huge portion of the Evince API has changed (a quick look seem to suggest that the entire document loading model is different).
I'm not sure how easy it would be port to the new API, but it looks like it will take some time.

This suggests that the python bindings have been updated already to the new API:

Yeah, the evince python binding in f12 and f13 follows ​http://library.gnome.org/devel/libevview/2.30/

The changes aren't major, just a few renamed methods and a separation between Documents and Models.

[lucian]

After trying my hand at porting Read, I found out that the following are truly gone:

• evince.View.set_screen_dpi
• evince.View.props.zoom

I've reported this as a bug ​https://bugzilla.gnome.org/show_bug.cgi?id=624780

[lucian]

I ported Read to libevview 2.80. The only lost feature is set_screen_dpi, but it's possible that libevview 2.80 can do that itself.

Note that I've made two merge requests, the first one has the wrong branch.

[lucian]

My mistake, I meant 2.30, not 2.80.

There's further issues with gnome-python2-evince 2.31.x due to the following changes in the evince api linked. This will affect both SoaS v4 based on Fedora 14 and the new OLPC F-14 builds so a fix would be appreciated.

Applied, but not tested, as I have no dev environment right now.

I have fixed the the bindings in F14 and sent upstream.

OLPC ticket ​http://dev.laptop.org/ticket/10618

Gnome ticket ​https://bugzilla.gnome.org/show_bug.cgi?id=639758

We need the bindings packaged now, anybody who can help?

[sascha_silbe]

Lucians fix has been landed as ​5832d4d, additional EPUB fixes have been committed as ​5aa9840. Is there anything left to do or can we close this ticket?

[godiard]

The bindings are package in Fedora and Read 89 was published.
