I know that, but it wasn't entirely clear that this is why phpdocx
includes a copy of tcpdf. dompdf doesn't ship with tcpdf itself, and
other things that embed dompdf don't necessarily also include tcpdf. So,
I had that as a possible theory, but wasn't sure it was the reason. Do
you know for sure that this is in fact the reason? If so, it makes
things easier for sure, as it just lifts right out...

So, the best web 'portal' would I guess be pkgdb, though I don't really
use it much myself:


note the links to 'Package Info' and 'Package Source'. 'Package Source'
will take you to the git repo where we keep our actual package builds,
I'll assume you can read a spec file well enough to steal the relevant
bits, but yell if you can't :)

Our git repos are branched per fedora release, 'master' is Rawhide (like
sid), that's probably the most interesting one to look at as it's where
we have 6.0.0a and where we're currently hacking on new unbundling. So,
http://pkgs.fedoraproject.org/cgit/owncloud.git/tree/owncloud.spec is
our current 'state of the art', more or less.

Right now we have OC 6.0.0a in Rawhide depending on the system copy of
DBAL 2.3.4, and yes, at first I found exactly the same thing! (No-one's
supposed to run anything close to production on Rawhide, so it's okay
when we do this kind of thing). A couple of days ago I backported enough
of the OC DBAL patches to our DBAL package that at least a MySQL upgrade
(mine) worked. Upstream has now landed almost all the OC patches on the
2.4 branch, so getting a DBAL 2.4 that should be good for OC is merely a
matter of building 2.4.1 with cherry-picked patches, and hoping the
2.3/2.4 diff doesn't matter: according to
https://github.com/doctrine/dbal/blob/2.4/UPGRADE , the only thing
that's backwards incompatible between 2.3 and 2.4 is "custom classes
that implement the constraint interface"; I'm not sure whether OC has
any of those, I meant to have a look.

In the end I dashed off irods last night, and yeah, the Debian package
was a big help, I followed the approach of ripping out a lot of the crap
in the tarball and also stole the description wholesale. =) thanks!
