xpa module conflicts with imexam

[olebole]

Original bug (Ubuntu): https://bugs.launchpad.net/bugs/1733352

Pyds9 does not play together with imexam. While both have overlapping use cases, it may be good that a user has the opportunity to install and use them in parallel. One way could be to make the package a subpackage of pyds9, another to agree on a common xpa package.

See also spacetelescope/imexam#122 for the imexam issue.

@olebole the current trunk installs also xpa stuff in a pyds9 directory, so there should be no more xpa from the pyds9 side laying directly in site-packages directory.

Any release plans?

[montefra]

I would like to release.

Most of the work that I have done has been moving pyds9 to astropy utilities. I can build and test in linux and mac, but it fails to build on windows (see #44). I would like to give a try again at it and see if I can do something about it.

@jehturner pointed out in spacetelescope/imexam#122 (comment) that the issue is solved in the current development version. Is this true? If yes, could I get the relevant commit (to include it into the Debian package), or maybe a new release?

[montefra]

yes, I think so. In the development version everything is installed under pyds9/ so there should be no name collision.

If @ericmandel has nothing against it I can tag the current master as 1.9.0.rc1: would that work for you?

[olebole]

Yes. This would however mean that 1.9.0.rc1will probably (if no other release comes out before) will be part of Ubuntu 18.04 LTS.

[montefra]

when do you have the package freeze?

[ericmandel]

@montefra I have no objections to tagging the current as 1.9.0rc1.

[olebole]

@montefra March 1 is the DebianImportFreeze.
