[Pkg-raspi-maintainers] Bug#856413: gpiozero: please provide python module on all architectures

[peter green]

I have chatted with Dave Jones (waveform80) about getting gpiozero support on more architectures. It seems sensible that as part of doing this we also package pigpio to support remote gpio operations.

Dominik do you mind if I add myself to the uploaders for this package and work on updating it to the lastest upstream version opening up the architecture list?

One thing we need to look at is making sure pi-specific code that hits hardware directly doesn't run on anything other than Pis. Both in gpiozero and in pigpio. Obviously this is a potential issue now but the risk rises as we package more stuff. I spoke to Dave about this at Manchester raspberry jam and he told me he had improved the detection in gpiozero recently, but the version at https://github.com/rpi-distro/python-gpiozero still seems to have the same code.

Dave is there an "experimental" gpiozero repository somewhere I have failed to find?

The gpiozero packaging in Debian and the gpiozero packaging in the raspberry pi foundation repo seem to be unrelated. This bug report is discussing the former.

No, you have them packaged in the rasperry pi foundation repo.

And looking at that packaging it's going to need some work before
it's something acceptable to upload to Debian.

Right now the python stuff is directed to it's own binary packages but
all the c stuff is stuffed into one binary package. I see several issues
with this package.

1. It contains not one but three shared libaries, none of which seem to have proper so-versioning
2. It seems to have a directory for some sort of scripts in /opt/pigpio/cgi, I don't think this compiles with the filesystem heirachy standard.

I will follow up these issues in more detail in another mail with a different recipient list (which will include https://bugs.debian.org/908787 but not https://bugs.debian.org/856413 )
