py34-aplpy @0.9.12 py34-pyregion is not available

[epaell]

py34-pyregion doesn't appear to be available. It is required when overlaying DS9 regions onto FITS images e.g.

import aplpy

fig = aplpy.FITSFigure("test.fits")
fig.show_regions("test.reg")

results in

> python3.4 test.py

During handling of the above exception, another exception occurred:

Perhaps pyregion should be added as a dependency or as a variant?

Cc Me!

In r126380 I replaces py31 and py32 subports (no dependents) with py33 and py34 as openmaintainer. This should solve this issue.

Log file for port py34-pyregion

[epaell]

I've tried to install py34-pyregion but I ran into an error (I've attached the log). I'm not sure if this is something associated with my system or whether it is an issue with the py34-pyregion port. It is probably worth pointing out that py27-pyregion installs fine on my system and also that it is a dependency of py27-aplpy.

[petrrr]

Okay, I will try to reproduce this.

[petrrr]

For me py27-pyregion fails as well. There is actually already an active ticket documenting this: #44391. I'd assume it is the same issue.

Can you tell when you installed py27-pyregion? May it predate the switch from distribute to setuptools?

[epaell]

You may be right about this, I expect that it may have been a while since I last installed py27-pyregion. I checked the date of the python site-packages directory and it had 23 Jan 2014 - I'm not sure if this accurately reflects the last install/update date? I tried to uninstall/install py27-pyregion as a test and that was when I realised that it was a dependency of py27-aplpy and I was reluctant to uninstall aplpy as well since this is a package I actively use and didn't want to end up in a situation where it was no longer functional. If this will ultimately be resolved with a fix to #44391 then it is fine to close off this ticket.

[petrrr]

I will try to have a look at #44391 at some occasion, at least if the maintainer does not do this before.

For now, I leave open this ticket. The maintainers of py27-aplpy might want to check for correct dependencies.

[epaell]

Since my last post I upgraded to Yosemite this gave me the opportunity to reinstall my entire macports tree. Interestingly, I was still able to install py27-pyregion despite starting from scratch. Alas, py34-pyregion still fails with the same error.

[petrrr]

This ticket is compiled against py-aplpy, so formally it would be better to track the py34-pyregion build failure elsewhere.

I would propose to track this in ticket #44391.

[petrrr]

However, before closing this ticket, we should check if dependencies are specified correctly.

[petrrr]

Changeset r127112 removes py32 in preparation of further changes.

[petrrr]

r127114 removes to condition for special Py3 handling of variants. This is not necessary as Py3 should be fully supported.

[petrrr]

I would propose to remove the +montage variant which was deprecated in r105631 ca 18 month ago.

[petrrr]

I hopefully fixed py-pyregion in r127116. Please check if all is okay now.

[epaell]

That seems to have resolved the install issue with py34-region. Thanks.

[petrrr]

In r129172 I updated py-pyregion to 1.1.4. This allows to remove the patch introduced in r127116. I also replace py26 and py33 at that occasion due to the deprecation process.

[petrrr]

In r129173 I updated to 0.9.14 and did some further changes as follows:

• fix livecheck
• PyPI pattern & minor formating
• remove +montage variant
• replace py{26,33} subports with py{27,34} respectively

I'd assume the port in now okay. So I will close this.
