By "counter-productive", I meant: likely to generate more confusion
than
clarity. If you provide an epoch in the version and it doesn't match
downstream packagers ones, it's hard to rely on it.
I see what you mean now. The thing is that for Debian/Fedora the epoch
syntax is different from PEP 440
For them it's
[distro-epoch]:[upstream-version][otherstuff]
PEP 440 epochs are separated by a !, so let's say $(distro) has an epoch
value of "1" and we choose "2", for glance the version would look ugly
but
would be:
1:2!11.0.0
<SNIP>
This would be a problem for at least Ubuntu and Debian as the version
string is specifically not allowed to contain a '!'.
"The upstream_version may contain only alphanumerics and the characters .
+- : ~ (full stop, plus, hyphen, colon, tilde) and should start with a
digit." [0]
Thanks for the input Dave. I didn't see that part since I was specifically
looking for how epochs are denoted. I still am quite certain that we have
no choice but to use the proper versioning tools upstream though and that
means using ! to indicate the epoch in our version strings because these
are fundamentally Python packages.
+1 we produce python versions, and people use them (whether they are
uploaded to pypi or not) so we should try to do the right thing here no
matter what. If downstream distro (rh, ubuntu, other...) wants to
convert that into its local epoch scheme that's cool (and I would expect
them to do that in the correct manner that is appropriate for there
packages).
Therefore, these distro's would need to increment the distro epoch if the
upstream version (without the upstream epoch) is lower than the version
currently in their archives.
I am not sure how rpm based distro's handle '!' in the upstream version.
In other words, if Debian/Ubuntu currently have Glance versioned:
1:2015.1.0
They'll be doing
2:8.0.0
For Liberty?
