Aleksey,
I tried out your patches in a Debian Sid chroot with
zeroinstall-injector-0.42.1-1
installed and got the following exception in shell.log when running your test
case:

The problem seems to be that you haven't told the policy object to solve the
feeds. You can do that with
policy.solve_with_downloads()
and maybe in other ways too.
yeah, in my testing environment I have remains from previous 0install
sessions
Anyway, after teaching zdepend.py to solve the policy, I ran into into further
trouble because my zeroinstall trust-db doesn't contain the ROX keys.
To deal with this, I think you need to construct the policy object with a
Handler object
http://0install.net/python-api/html/zeroinstall.injector.handler.Handler-class.html
and override its confirm_keys method.
I've pushed new commits with fixed these issues and added cancel button
@Thomas, Rene: is this about right?

First up, to be honest, I don't plan to use or involve myself with 0install for any activities I'm involved with (may be if it works invisibly as a worst case fallback)... if you have ready to use 0depend.xml file(for example from another activity which uses the same deps) you as developer should only place it to activity/ directory and for users starting this activity means only having additional downloading progressbar(for the first time). But, if a deployment/teacher wanted to distribute one (or several) of these non-Sugar compliant installs on a USB stick for remote class installation, is it a trivial step for them to put 'the activity' on a stick so it can be installed without any network access or local server at install time? 0install integration is just an optional addon to activity bundles, you can all time package fat .xos as usual. Example: Teacher travels from a remote village to an education ministry or town with internet access once a month. Downloads a selection of new activities and content from ASLO to their USB stick. Journeys back to their village and uses the USB stick to install/upgrade each machine, kids also share the activity .xo bundle from Journal with friends who can't make it to the school. http://wiki.sugarlabs.org/go/Zero_Install_integration#Deploy_0install_packages_from_ASLO_like_a_regular_sugar_activities as an addition, we can support offline mode for such activities (request for downloading all required deps for all such activities by one click). -- Aleksey ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel

So it'll be triggered when users download run an .xo? When they double-click an .xo from a USB disk? 0install procedures will be triggered on avery activity launch, but we can trigger them on uploading such bundle to journal(installation), so there won't be any differences (in case of downloading from ASLO) between regular activities and activities w/ 0install dependencies Will there be a way (control panel?) to see the disk space taken by 0install stuff and prune/uninstall parts? dunno, I guess in most cases its a designers question I thought about simple download progress bar for launcher http://wiki.sugarlabs.org/go/File:0depend-launcher.png, control panel for setup 0install settings and we can have context menu item for activities that have 0install dependencies to show 0install status. -- Aleksey ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel

Hi, I would like to know more about how the experience changes for activity authors 0depend is just optional feature, for bundles that have activity/0depend.xml file, while launching activity sugar(via 0install) will download(or build, just 0install feature) all dependencies that are mentioned in 0depend.xml and pass proper info via environment variables (PATH, PYTHONPATH etc) to activity startup. and what happens when the .xo is not downloaded from the web but copied from an usb stick. only 0depend.xml makes sense(its just regular bundle file), if it exists, shell will enable 0install integration.
