[gentoo-dev] Portage 1.5 improvements list

[drobbins]

Hiya,

I just committed yet another bug fix to Portage 1.5_pre1.

So far, I have the following features to add for 1.5_final:

1. Don't use the "rev" in the package database.  Packages with the same
version, but different "rev" overwrite each other.  Record revision in
a REVISION file in /var/db/pkg.

Possibly:
	
	Only allow one version of a package installed at a time.
	Override with a DIFFVERSION= setting in the ebuild:

	DIFFVERSION="major" means "allow the same package with differing major
	versions to be installed"

	DIFFVERSION="minor" would allow foo-1.2 and foo-1.3 to be installed at
	the same time, but not foo-1.2 and foo-1.2.1
	
Comments welcome.

If a package provides for example virtual/mta, does it work to add
!virtual/mta to RDEPEND to prevent installation of duplicate mta's ?
 I would call the variable MULTIPLE because DIFFVERSION is abit to long in my
eyes.

OK, MULTIPLE is good. 

Ah, another thing I need to add -- pkgmerge virtual merging support.  This gets
complicated; part of me thinks that the *user* should choose the proper virtual
package, rather than us selecting for them.  At first, I was thinking that the
first package listed in /usr/portage/virtual-update would be used, but now I
think that's too simplistic.  I don't want Portage to automatically install
qmail for someone -- I think that they (for safety reasons) should be involved
in that choice.

Right now, a recursive pkgmerge will fail if it gets to a virtual dependency.
It'll let the user know that it couldn't find "virtual/mta" and it will be up
to the user to resolve it.  Comments?

!virtual/mta should be added to RDEPEND (for package installs) and DEPEND (for
ebuild merges).  It should work (hasn't been tested yet).  I don't think it
should be automatically added by Portage, but should be specified by the ebuild
maintainer.  Jerry, could you make these two fixes to qmail, exim and postfix?

Okay, quick question.  Should the syntax be:

DEPEND="!=virtual/mta"

or:

DEPEND="!virtual/mta"

!virtual/mta, as I wrote in the previous email.

But why DEPEND, you should still be able to make an exim package if you have qmail
installed.
I think it is ok to use it in RDEPEND only.

Makes sense.  Quick question, will a portage still merge if only RDEPEND
is set?

The reason I ask is since each portage in virtual/mta creates
/usr/sbin/sendmail, etc... multiple virtual/mta installations will just
trash the previous one.

I did not have the time to test portage 1.5 yet. But I think that pkgmerge
only tests RDEPEND.
So adding !virtual/mta to DEPEND whould not change pkgmerges behaviour.
Lets wait for daniels answer.

Right now, runtime dependencies are checked *after* a package is merged from sources.
Probably the best solution to this problem is for me to move this check to before the
merge, as it is with a pkgmerge.  Another portage fix :)

The answer is: right now, the RDEPEND setting will prevent a package merge,
but won't prevent a source merge.  I'll fix this in a few minutes (after
I check all my emails) on CVS.

Can you add a flag which forces merge even if RDEPEND is not satisfied?

Yes.  I now have a "TODO" doc in /usr/share/doc/portage-1.5_pre2 which
contains all the things I need to add to portage.  I listed this addition
there.
