What about my precious Xpdf ?!?!?

I keep getting e-mails asking me why app-text/xpdf is masked for removal from the portage tree. It's getting too much to reply individually, so let me sum up the situation here in a blog post.

# Andreas K. Hüttel <dilfridge@gentoo.org> (27 Jan 2012)
# Has developed into an unmaintainable mess, and everyone who
# knows about it is either retired or missing in action.
# Several minor bugs and one ugly security issues (#386271).
# Masked for removal because of lack of maintainer.
# Please try app-text/epdfview as light-weight replacement.
app-text/xpdf

Xpdf is a package with a long history, and in a way a strange remnant of bygone times. Since PDF rendering is a function that many different programs could use, some years ago the Poppler library was forked from the Xpdf codebase. By now, Poppler is a much more active project, and used by dozens of packages in the Gentoo portage tree, all the way from LibreOffice and PDFTeX to Calligra, GIMP, and e.g. Okular or Evince. Being the more active project is important in this case, because PDF files are frequently shared and distributed and PDF rendering is thus a security-relevant task.
The original Xpdf remained independent of Poppler, not using the library - with the effect that every now and then security bugs kept popping up. Some time ago, some Gentoo developers started modifying and patching Xpdf to use the Poppler library. What resulted was the complicated construct that right now noone here is willing to maintain anymore. (Otherwise some Gentoo developer would have contacted me in the meantime.) Implementing a version bump to a more recent Xpdf version is a non-trivial task because all the Gentoo-specific patches have to be reviewed and if necessary rewritten.
Thus, app-text/xpdf needs to go the way of the dinosaur. Two alternatives exist, but both do not seem realistic at the moment:
1) We could go back to the original, unpatched Xpdf from upstream. I'm not going to do it, and I doubt anyone else of the Gentoo devs will.
2) Rogério Brito has started maintaining a fork of Xpdf at Github, which uses the Poppler library. However, there is no released version yet, and as he told me myself, he's rather busy in real life right now...
In the meantime, please try one of the following packages:

• app-text/zathura (based on poppler & gtk+)
• app-text/apvlv (based on poppler & gtk+)
• app-text/epdfview (based on poppler & gtk+, ~unmaintained)
• app-text/mupdf
• app-text/gv (based on ghostscript)
• app-text/evince (based on poppler, Gnome application)
• kde-base/okular (based on poppler, KDE application)
• app-text/acroread (yes I know...)

Ironically, the first mail reply to the last-riting of xpdf was from one of our security team members, promising me a beer the next time we meet in person. Only afterwards the complaints started.
