[gentoo-dev] emerge -Up tetex wants to downgrade

[Denys Duchier]

Dear devs,

I asked this question on the gentoo-user list, but did not get any
useful answer.  Can someone on the dev list please has a quick look:

"emerge -U" is not behaving as I would expect.  I discovered this
while trying "emerge -Up world" to see what I needed to update.
Here is what I get:


% emerge -Up tetex
>>> --upgradeonly implies --update... adding --update to options.

These are the packages that I would merge, in order:

Calculating world dependencies ...done!
[ebuild    UD] app-text/tetex-1.0.7-r12 [2.0-r1]


% ACCEPT_KEYWORDS="~x86" emerge -Up tetex
>>> --upgradeonly implies --update... adding --update to options.

These are the packages that I would merge, in order:

Calculating dependencies ...done!
[ebuild    U ] app-shells/bash-2.05b-r4 [2.05b-r3]
[ebuild    U ] dev-util/dialog-0.9_beta20030308-r1 [0.9_beta20020814]
[ebuild    U ] app-text/tetex-2.0.2 [2.0-r1]


--upgradeonly (-U) is documented as follows:

    "Updates packages, but excludes updates that would result in a
    lower version of the package being installed. SLOTs are considered
    at a basic level."

I have no idea what the last sentence is supposed to mean, but the
first sentence promises exactly what I want: namely to not
downgrade... but that's not what emerge delivers.  Is that an error of
documentation, of implementation, or of interpretation on my part?

Without such an option (with the semantics that I want), it is
extremely inconvenient to upgrade your system, while not downgrading
the select few ~x86 packages that you have emerged.

Any insights?

Cheers,
