Summary:                    lunar doesn't correctly calculate zlocal
dependencies
Description: 
Hi,

The /var/state/lunar/depends.cache file contains the dependencies of all
modules : official and zlocal modules. If a module is in zlocal and
official moonbase, the dependencies are calculated on zlocal and official
module.
zlocal dependencies don't override official depends, zlocal dependencies
are added to official depends.

And this is a problem when you create a zlocal module that contains
DEPENDS which conflicts with official DEPENDS.

How to reproduce :
lvu edit <module>
remove a dependency of /var/lib/lunar/moonbase/zlocal/<module>/DEPENDS
lin -r <module>
=> lunar always compile the dependency you removed.

I rebuilt the depends.cache file with lsh but official dependency is
always added to zlocal dependency.

I tried to modify the function create_depends_cache of depends.lunar but
I'm not good at programming and was unable to find a soluce.

The only way I found to solve this problem is to manually modify the
depends.cache after it has been generated.

This problem has long been the biggest annoyance for me.
I asked about this in mailing list months ago, but didn't get much
response,
so I have had no idea whether this is a problem developers aren't aware,
or is a intentional behavior.

Making "/var/state/lunar/depends.cache" a empty file is a easier way to
(temporary) solve the problem. (mentioned by florin in mailing list)
It's certainly easier, but will work only until your next lunar update
and
lvu tree and some other will be useless ^^;
Anyway, I wanna see this is solved.

several ways to fix this:

1. lin moonbase 
will rebuild that .cache file... So all you really
need to do after deleting a depends from a DEPENDS file is lin
moonbase... this will solve your problems...

there are other ways but they are not advised for the mortal user:

2. hand edit the /var/state/lunar/depends* files and delete the
entries of the module you are editing. after that lin -cr MODULE
3. "lsh create_depends_cache" and then lin -cr MODULE

AGAIN these 2 last ways are really not recommended and lin moonbase
works just as well ;)

hi El_Angelo.
Yes, those ways supposed to fix my problem. But it doesn't...
The reporter(Sirocco)says,

"I rebuilt the depends.cache file with lsh but official dependency is
always added to zlocal dependency."

and this is exactly what I got too. I just tried to reproduce this problem
again, and of course I could get the same results again.

create_depends_cache just combines required depends from
/var/lib/lunar/moonbase/<ORIGINAL-SECTION>/<MODULE-1>/DEPENDS and
/var/lib/lunar/moonbase/zlocal/<MODULE-1>/DEPENDS.

For example, when you wanna update a old module TestModule-2.1 which
requires gtk+, to new version TestModule-3.8 which requires gtk+-2, I
think you will replace "depends gtk+" with "depends gtk+-2".

But in that case, both gtk+ & gtk+-2 will be listed as required module in
depends.cache, even after "lin moonbase" or "create_modules_index &&
create_depends_cache".

sorry if my explaination is confusing...
but I hope you can understand I(and likely sirrocco as well) have already
done what you suggested.
