10 I'd like the Council to raise the topic of using stable USE masks
11 in gx86 tree.
13 The issue is that Python packages have USE-conditional (PYTHON_TARGETS)
14 dependencies upon new, unstable Python versions. Therefore,
15 if a particular package is to be stabilized, the relevant USE flags have
16 to be masked (or removed) in order to fulfill the dependencies
17 on a stable system.
19 Currently we're resolving this through using two revisions
20 for a package, one with the relevant flags removed (going stable)
21 and a newer one with all flags enabled. However, this is very
22 inconvenient for us.
24 EAPI 5 provides use.stable.mask files to solve this but those files
25 require profiles to be EAPI 5. Therefore, in order to be able to use it
26 we would have to actually break the update path for older portage
27 versions completely.
29 I have tried to raise the topic on the mailing list [1] but it mostly
30 resulted in some people agreeing that it is an issue that should be
31 addressed but no real ideas.
33 I have come up with three possible solutions myself. Long story short:
35 a) adding new profiles which will require EAPI=5 and requiring all
36 users to migrate to them after upgrading portage. Using new
37 use.stable.mask files in those profiles.
39 b) adding new profiles (with current EAPIs) and requesting our unstable
40 users to migrate to them. Masking the relevant USE flags globally
41 and unmasking in those profiles.
43 c) 'fixing' the use.stable.mask feature and wording it in such a way
44 that it would apply to EAPI 5 (or 6) packages independently of profiles
45 EAPI.
47 I have also opened bug 447090 [2] in order to try to get some feedback
48 on b) but nobody bothered to answer.
