Please backport spyder 2.3.0+dfsg-3 (universe) from utopic

[Stephen Michael Kellat]

Please backport spyder 2.3.0+dfsg-3 (universe) from utopic to trusty.

Reason for the backport:
========================
1. New support for Python 3
2. jedi autocompletion now possible

Testing:
========
Mark off items in the checklist [X] as you test them, but please leave the checklist so that backporters can quickly evaluate the state of testing.

You can test-build the backport in your PPA with backportpackage:
$ backportpackage -u ppa:skellat/tests -s utopic -d trusty spyder

* trusty:
[X] Package builds without modification
[X] spyder3 installs cleanly and runs
[X] python-spyderlib installs cleanly and runs
[X] python-spyderlib-doc installs cleanly and runs
[X] python3-spyderlib installs cleanly and runs
[X] spyder-common installs cleanly and runs
[X] spyder installs cleanly and runs

Reverse dependencies:
=====================
The following reverse-dependencies need to be tested against the new version of spyder. For reverse-build-dependencies (-Indep), please test that the package still builds against the new spyder. For reverse-dependencies, please test that the version of the package currently in the release still works with the new spyder installed. Reverse- Recommends, Suggests, and Enhances don't need to be tested, and are listed for completeness-sake.

Backported package from utopic fails installation in these areas:

[ ] spyder3 installs cleanly and runs
[ ] python-spyderlib installs cleanly and runs
[ ] python-spyderlib-doc installs cleanly and runs
[ ] python3-spyderlib installs cleanly and runs
[ ] spyder-common installs cleanly and runs
[ ] spyder installs cleanly and runs

apt-get reported that the packages spyder3 and python3-spyderlib were not co-installable, for example.

[Stephen Michael Kellat (skellat)]

Narrowing it down, the dependency spyder3 has on python3-spyderlib is a hard one for a specific version shown here: http://packages.ubuntu.com/utopic/spyder3

Due to the packaging and the use of a PPA for testing, the backportpackage script breaks it by giving it a technically lower version number than the hard dependency that is built in.

[Scott Kitterman (kitterman)]

spyder3 and python3-spyder are built from the same source package, so if you rebuild them both, the spyder3 version requirement will be the same as the python3-spyder version. The = version dependency is generated at build time.

The reverse depends will need testing. If the existing versions don't work with the new python-spyder, then they can be backported too as part of a set.

 This is the line from the buildlog that has me scratching my head:

dpkg-source: warning: unknown information field 'Breakes' in input data in package's section of control info file

(https://launchpadlibrarian.net/181291293/buildlog_ubuntu-trusty-i386.spyder_2.3.0%2Bdfsg-2~ubuntu14.04.1~ppa1_UPLOADING.txt.gz)

I ran dget -x http://archive.ubuntu.com/ubuntu/pool/universe/s/spyder/spyder_2.3.0+dfsg-2.dsc to download and break apart the original source package from utopic. The oddball "Breakes" shows up in the control for python3-spyderlib.

[Stephen Michael Kellat (skellat)]

The source package builds not installable things as far as I've been able to attempt.

[Felix Geyer (debfx)]

> dpkg-source: warning: unknown information field 'Breakes' in input data in package's section of control info file

That's a bug in the package. I've filed bug #756803 on the Debian bugtracker.
However the lack of that Breaks field is not a huge issue in practice.

[Stephen Michael Kellat (skellat)]

Running a new build with new version that just auto-landed

[Stephen Michael Kellat (skellat)]

Python 2 & 3 versions both come up, display About boxes, start shells, and accept keyboard input. I'll accept that as running for now. I'll deal with the rdepends after some sleep and after I go to church.

[Scott Kitterman (kitterman)]

FYI, the Breaks issue is now fixed in Debian and Ubuntu Utopic, so when we do the actual backport, it won't have that issue.

[Stephen Michael Kellat (skellat)]

Tests are done. I'm not going to attempt "science-numericalcomputation" installation as it is not a required test plus brings in another gigabyte of packages.

[Scott Kitterman (kitterman)]

Package requires manual accept for backports, but it's been uploaded.

Package built/accepted. It should be available after the next publisher run +
some time for the mirrors.
