Bug 181713

Last time I tried submitting builds, the buildsystem wasn't working.  Thanks for
reminding me to resubmit the job.

 4525 (lyx): Build on target fedora-4-extras succeeded.
     Build logs may be found at
http://buildsys.fedoraproject.org/logs/fedora-4-extras/4525-lyx-1.3.7-5.fc4/

It appears that upgrading lyx, installs lyx-xforms, as the graphics backend, but
not lyx-qt, the qt backend.  Given that the 1.3.6 version exclusively used the
qt GUI, it violates the principle of least surprise that the upgrade doesn't
include the qt backend, so I would expect that an upgrade should install the
lyx-qt backend rather than the xforms backend.

i.e. lyx-xforms should be the optional package, rather than the default.

Actually, you can install *either* lyx-qt or lyx-xforms.  There is no default.

In my testing, a regular
yum update
installed lyx-qt. ??  I guessed that was because yum chose lyx-qt over
lyx-xforms because it comes first alphabetically, but now, who knows?

I was actually using smart, not yum, to upgrade, it chose lyx-xforms.  It has a
slighly different depsolver to figure out what to upgrade.  Still, I think that
for somebody who is *upgrading* from lyx-1.3.6, lyx-qt should always be
installed, because that mirrors the 1.3.6 functionality.  Of course, *after*
that installation they can chose between lyx-xforms and lyx-qt (or both).  

Presumably lyx is non-functional without one or the other, though, so *some*
default needs to be chosen for upgrades.

I'll test what both to see what smart and yum do.

I chose not to make any default so folks that want lyx-xforms won't have to
install lyx-qt too, even though they don't use it.

Regardless, *this* bug (lyx-1.3.7 needs to be built for FC-4) is closed.  

If you want to pursue this other issue, please open a new report.

OK, here's what smart and yum do:

smart upgrades to lyx-xforms

Doing a fresh install, smart again only wants to install lyx-xforms:

I think the requires should be amended so that lyx-qt is always installed, so
that smart will also do the right thing like yum does.  It bothers me that the
upgrade path is non-deterministic and in this case, just happens to depend on
which package manager you are using, it should be under the control of the packager.

I'm strongly against forcing any particular front-end on anyone.  End users
should be free to choose.

If you don't like that, and have an idea on how to implement your wishes and
mine, I'd love to hear it (in a separately filed bugzilla report please).

Understood.  If lyx-xform is explicitly chosen, then lyx-qt should *not* be
installed, I'm only talking about the case of either upgrading from lyx-1.3.6
*or* if only lyx is specified (with no explicit request for either -qt or -xforms).

Sure.
