[gentoo-dev] Policy with dependencies

[gentoo-dev] Policy with dependencies

[Karl Trygve Kalleberg]

I'm working on packaging a system tool called subterfugue [sic]. It can be
thought of as a very jazzed up version of strace.

It is written Python. Some of its operating modes, such as NetThrottle
(sets a limit on the bandwidth a particular process may eat) requires
pygtk, but most (if not all) the other scripts for subterfugue do not.

For sf to depend on pygtk, it will depend on gnome, x11 and a slew of
other packages, even though 95% of sf itself is ideally suited for an
X-free (no X) box.

Merging in pygtk later on makes it work perfectly.

Should I just make a not in post_install() about this, and don't bother
with the pygtk dependency ?


Kind regards,

Karl T

You could add dependencies only if use gtk is set, and/or only install 
if use gtk is set.

Anyway this shouldn't be up to the developer, but there should be a 
policy for this.

Best idea so far. I'll go with this for now.

Agreed.

I've been complaining about lacking guidelines for ebuilds for a long
while now. I'll continue until we've resolved it.

Hmm .. is NetThrottle a corepart of this package?
USE-variables should only be used to decide wether to build optional
support for something. If coreparts requires something it can be thought
of that the entire package does.

If this however decides whether a GUI for NetThrottle will be built
(otherwise just available through console-interface) USE=gtk should be
used.

Why will it depend on gnome? pygnome only depends on GNOME if USE=gnome,
otherwise it just builds pygtk.

Depends on what you mean by 'core part'. Just like cvs offers a lot of
commands, such as commit, update, checkout, admin, Subterfugue offers a
list of commands built as modules. 

If you want to use the NetThrottle command (and I would assume very few
people would), you have to have PyGTK installed. Note that since
Subterfugue is written in Python, PyGTK is not a compile-time dependency,
it is optionally a runtime dependency.

Again, since this is Python, you can compile the code without having the
dependencies available.

Because PyGTK depends on libglade which in turn depends on GNOME.
