I don't like "pre" or "rc", as they are often used by upstream
programs. Also, pre and rc tend to mean that foo-2.1pre1 is actually
before foo-2.1. We could end up having "1.2pre3" as the most recent
upstream version, with 1.2 not having appeared. What do we do then, and
how do we make it sort?
I think we agree that we use an 8-digit ISO8601 date.
What we need here is to agree on two things:
what version of the upstream package should we use: the most recent
release, or the release we think will happen next?
what separator method to use between the upstream version and the date
For version, I think we should use the most recent previous version. So
if upstream released 1.5, and we think is going to release 1.6 next, we
should have something that is "1.5 <tbd> 20160620". This makes sorting
right without magic rules about "pre" being before what it is labeling.
We have "nb" as a special separator for PKGREVISION. Non-releases are
sort of like PKGREVISION in that we apply it to versions, except that
it's an upstream thing, and we need PKGREVISION too, for a different
reason.
So I suggest "ur" to mean "unreleased", and to add it as a separator
token, with the rule that a version is
version
[unreleased date]
[nbrevision]
So that something might look like
foo-1.5ur20160610nb2
we could even have a
UNRELEASED_VERSION=yyyymmdd
in Makefiles similar to how we have PKGREVISION.
This has slightly (really?) ugly syntax, but is semantically clean.
The way to clean it up is to get upstreams to have releases :-)
A less ugly but slightly unreliable proposal:
I would prefer to just use 1.5.20160610, but we can't be sure that
upstream will release 1.6 and not 1.5.1. So we'd have to use
1.5.0.20160610
figuring that the odds that upstream will release 1.5.0.1 next after 1.5
is near zero (for a package where we need to use non-releases).
I'd be fine with either "0.${UNRELEASED_VERSON}" or
"ur${UNRELEASED_VERSION}.
