Provide sugar version in user-agent string

[alsroot]

This feature will let ASLO to recognize version of current environment and add hints to prevent downloading incompatible activity versions.

The format of user-agent substring that ASLO can understand is:
"Sugar Labs/<major-version>.<minor-version>"

Currently jhconvert distros use this

Thanks for the patch. We moved the vendor information to the package.

and from the Fedora rpm:

%prep
%setup -q

cat >> data/prefs.js << EOF
pref("general.useragent.vendor", "OLPC");
pref("general.useragent.vendorSub", "%{version}-%{release}");
pref("general.useragent.vendorComment", "XO");
EOF

I will think about how we can handle that best. The vendor OLPC is used by the olpc web services afaik.

[alsroot]

at the end idea is having substring with format
<prefix>/<major-sugar-version>.<minor-sugar-version>

so it could be placed to general.useragent.vendorComment field
use vendors(liek OLPC) could use general.useragent.vendor

[erikos]

I think we can use the vendorSub field for that. At the moment we place the hulehop version there, and I doubt someone does check for that. I think for browser recognition (web apps behavior) the pref("general.useragent.extra.firefox", "Firefox/3.0") is important.

Actually, placing the vendor "OLPC" in the Fedora package does not sound as a good idea anymore - as the Fedora package is used in Soas, Fedora installs and from OLPC. I guess if OLPC needs that distinction, the prefs needs to be patched later. What do others think?

What about using a gconf property? That way people can set the value either in the rpm or in the kickstart file, an update script, etc

[erikos]

Ok, the gconf property sounds good. Can the patch be rewritten taking this into account?

[erikos]

Used the vendor comment for the sugar version "pref("general.useragent.vendorComment", "Sugar Labs/@SP_VERSION@");", after discussing with Aleksey.

[erikos]

I think we have a good solution for now.
