Public bug reported: Impact ------
This is a minor bugfix release of the 1.6.x series: https://wpewebkit.org/release/wpebackend-fdo-1.6.1.html The version currently in 20.04 LTS is 1.6.0, which accidentally shipped with a bug that made the symbols wpe_fdo_get_{major,minor,micro}_version hidden. These were supposed to be public (which is fixed in 1.6.1) and can be used by other components to check the installed version at runtime. In particular WebKitGTK depends on wpebackend-fdo, and we expect future security updates may use these functions. The WebKitGTK team has committed to making it possible for 20.04 to get updates until April 2023, and this update makes those possible. Users of WebKit-based browsers should be able to browse the Web with an up-to-date WebKitGTK stack that receives security updates :) Test Plan --------- The following C program can be used to check that the bug is present before the wpebackend-fdo update, and that the issue was fixed afterwards: /* * $CC -o wpefdoversion wpefdoversion.c $(pkg-config --cflags --libs wpebackend-fdo-1.0) * * This will: * - Fail to link with wpebackend-fdo 1.6.0 * - Succeed with version 1.6.1 */ #include <wpe/fdo.h> #include <stdio.h> int main(int argc, char *argv[]) { printf("wpebackend-fdo runtime version: %d.%d.%d\n", wpe_fdo_get_major_version(), wpe_fdo_get_minor_version(), wpe_fdo_get_micro_version()); return 0; } Browsers which use WebKitGTK for rendering web content running in a Wayland session use wpebackend-fdo. Loading e.g. https://people.igalia.com/aperez/poster-circle.html in Epiphany (package epiphany-browser) should work the same before and after the update. What Could Go Wrong ------------------- Given the little amount of changes between versions 1.6.0 and 1.6.1, the possibility of breakage is minimal to none. Diff: https://github.com/Igalia/WPEBackend-fdo/compare/1.6.0...1.6.1 If there were unexpected build failures for the package, an alternative would be to continue shipping version 1.6.0 with commit 1dda80de5372e56cdc6f818a3fca493f7cc1f9d6 applied, which would solve the issue with the wpe_fdo_get_{major,minor,micro}_version symbols without including the rest of the changes from 1.6.1: https://github.com/Igalia/WPEBackend- fdo/commit/1dda80de5372e56cdc6f818a3fca493f7cc1f9d6 Finally, given that default installs of Ubuntu desktop do not include a WebKitGTK based browser, users are likely to have another web browser available if things were to go wrong. ** Affects: wpebackend-fdo (Ubuntu) Importance: Undecided Status: New ** Attachment added: "Test program C source" https://bugs.launchpad.net/bugs/1992854/+attachment/5623985/+files/wpefdoversion.c -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to wpebackend-fdo in Ubuntu. https://bugs.launchpad.net/bugs/1992854 Title: Update wpebackend-fdo to 1.6.1 Status in wpebackend-fdo package in Ubuntu: New Bug description: Impact ------ This is a minor bugfix release of the 1.6.x series: https://wpewebkit.org/release/wpebackend-fdo-1.6.1.html The version currently in 20.04 LTS is 1.6.0, which accidentally shipped with a bug that made the symbols wpe_fdo_get_{major,minor,micro}_version hidden.
