CHIP with subsurface

[Robert Helling]

Hi,

my progress on the CHIP has unfortunately been slower than I though originally (mainly because there are a number of things do do and each takes longer than expected).

Some things work, others not yet, but I see no fundamental obstacle, yet. All I have done so far works identically on CHIP and RaspberryPi. To be reproducible, I have logged all my steps here:

http://trac.subsurface-divelog.org/wiki/Subsurface%20on%20RPi

Currently, I could use help with three things:

1) Wifi Access point: i have the thing act like and access point. But iPhones, upon establishing a dhcp connection, phone home to apple and try to download http://www.apple.com/library/test/success.html to see if they are connected to the “real” internet rather than some hotel captive portal. As we do not provide that, we should respond to that request. I guess that means we have to run a DNS server and claim that we are www.apple.com and then serve that page.

2) Run a git server that also allows pushing commits (this is where last time I got stuck)

3) On the subsurface side: Make cloud storage work with more than one git server. Of course, Dirk’s server is the real cloud server. But the mobile version should also be able to sync with (pull/push) with http://subsurfacechip.local/git (I am not yet decided if we should require authentication in that case). This should not be too hard to add to the code, it’s just the order of pulling/pushing things that so far I did not get right. Note that this does not require any UI work, just subsurface-core. Just clone your dive repository, but it on a server and make sure subsurface talks both to cloud.subsurface-divelog.org and your server in a consistent way. That would be very much appreciated.

Once I have the basics running, I will try to have this covered by version control (rather than a list of steps in a wiki): Besides apt-getting some packages, I am mainly modifying (system) files. All those should at some point be under git and I will provide a script that copies those in the appropriate places). This would make it much easier to collaborate on these things. Of course, this is not meant as means to roll this out to users (those will get images or something like that) just for developers.

Have to run.

Best
Robert
