Re: [Sugar-devel] Activity crashes when using libsugarize.so
Bert wrote libsugarize only works for well-behaved simple X11 programs Hmmm. For me, libsugarize.so has worked even with complex X11 programs. I launch most of my third-party (Linux) applications from the command line -- but some number of them (e.g., Chrome, Labquest) I've sugarized so that others can launch them through Home View. Even though these applications are not simple, I've so far not encountered any problems: I point activity.info to the bash sugarize.script (rather than to the compiled sugarize.c) and make sure the bash script has the line export LD_PRELOAD=$SUGAR_BUNDLE_PATH/lib/libsugarize.so I then add in lines to the end of the bash script which set up the application's variables, then launch the application's executable. mikus p.s. Non-well-behaved programs (perhaps because they might open multiple windows) can leave behind gray circles in Frame when they close. I wish Sugar would automatically clean out icons from Frame once the X11 window|session (which that icon represents) has gone away. ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel

At this point, we think the crash comes not so much from libsugarize but from changing windows very quickly during startup. If we don't use libsugarize, Sugar doesn't recognize the window as interesting, and doesn't get the callbacks. I have a fixed-up libsugarize that doesn't cache the call results in a static var -- it was caching the window handle too. Not sure why it is structured like that, it doesn't seem to make sense with apps that may switch windows. If we do use libsugarize, Sugar gets the callbacks (jarabe.model.shell._window_opened_cb()) and crashes querying the window that was valid a ms ago, and now is no longer valid. This app (Adobe AIR stuff) seems to trigger 4 window switches (that trigger the callback) during startup. The crash doesn't always happen -- you gotta get the timining right for the race condition. We're tracing this to strengthen Sugar in the face of flipping windows -- so it won't crash. But it won't be able to keep track of the correct window for the app either. On the other side of the fence, I'm working with the upstream on the activity side so that it doesn't flip windows faster than the eye can see.

Re: [Sugar-devel] determine origin of file selected from an object chooser?
As far as I know there really is no need; when your activity saves state
(when exiting, etc.), it should save the copied file as part of the
activity's journal entry.
At least this is how it has always worked with Jukebox Read.
(As a side note, the Journal description for a copied item often states
the path where it came from, but I would not rely on this to tell you
that it came from an external source. The description or this feature
could change at any time.)

Re: [Sugar-devel] [Dextrose] [DESIGN] Reflect internet connectivity in the 'Network' frame icon
I'm pretty certain that the latest versions of Windows attempt to do determine if they have Internet or just local access, contacting a Microsoft server to see if they can reach it. However I would not recommend doing this unless you have the resources of Microsoft, or the permission to use the resources of someone who does. Netgear made the mistake of hardcoding the University of Wisconsin's NTP server in a bunch of their earlier products. Combined with a bug this caused the university to get 150 Mb/sec (250,000 packets/second) of NTP queries coming at them. This icon may also not be desirable on low-bandwidth connections, as even pings from 20-30 laptops could become measurable amounts of billed data. Some school servers may also run offline proxies which can request pages to be fetched from a remote online system later, and who knows what our icon should show in that case.

Re: [Sugar-devel] [DESIGN] Reflect internet connectivity in the 'Network' frame icon
It might indicate connectivity to either the school server, Jabber server, or successful NTP synchronisation. A deployment might customise what method to use, including hostnames of their own infrastructure. The default should be harmless. This feature is present on at least three modern consumer routers that I've used in the past six months, in the form of an extra LED called INTERNET. It isn't clear how it is implemented, but it seems quite reliable ... not indicating when I've got a problem loading pages, for example. -- James Cameron http://quozl.linux.org.au/ ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel

Re: [Sugar-devel] [Dextrose] [DESIGN] Reflect internet connectivity in the 'Network' frame icon
I believe (but am not 100% certain) that I read somewhere that the Microsoft approach uses HTTP. This likely is because if you are using an HTTP proxy, you may not have external DNS resolution or pinging ability. As far routers go, I don't know how many of them try to be smart and indicate full internet connectivity, while others may just acknowledge they have an active working DHCP lease or PPPoE connection. Most routers still try to use NTP to set their own clocks from the Internet so they could use that too, but hopefully they are a lot saner about using NTP than they used to be. What I'd like to avoid with this feature is falsely claiming Sugar is offline, and having some activity (Get Books, etc.), refuse to function because it thinks (incorrectly) it cannot do anything. We can warn if we want, but we don't want to be persistent about warning if a deployment is screwy to the point users ignore Sugar messages entirely.
