[Freewx-maint] Bug#790222: [boinc_dev] Bug#790222: wxwidgets3.0: depends on libwebkitgtk-1.0-0 which is deprecated

[Christian Beer]

Hi,

I'm not sure I fully understand the issue. So I'll try to explain what I
understood.

Debian is going to remove the package "libwebkitgtk-1.0-0" in testing
(buster) which will also remove the package "libwxgtk-webview3.0-0v5"
which is a dependency for package "boinc-manager" which means
"boinc-manager" will have a broken dependency.

One possible fix is to rebuild the package "libwxgtk-webview3.0-0v5"
using GTK3 which means all wxWidgets packages need to be rebuilt too.
Since "boinc-manager" is the only package using
"libwxgtk-webview3.0-0v5" you want to rather drop webview support on
Debian than rebuilding wxWidgets.

So our (BOINC's) options are rather limited in order to keep
"boinc-manager" working on Debian. We can start to look for an
alternative to wxWebView or disable it on Debian. But disabling is not
an option since we use wxWebView to communicate to the users of
boinc-manager via this simple but effective in-app browser. We also have
a tool that uses wxWebView to show a HTML page as a screensaver which is
easy for scientific projects to use.

Please correct me if I'm wrong and/or give some more options. I'm a bit
puzzled as to the fact that this feature of wxWidgets is not used by
more packages. Is there a history available which packages depended on
"libwxgtk-webview3.0-0v5" in the past so one can find out what they did?

Regards
Christian
