[Bug 1850932] Re: [SRU] Backport 2.62.4-1

[Steve Langasek]

Hello Iain, or anyone else affected,

Accepted glib2.0 into eoan-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/glib2.0/2.62.4-1~ubuntu19.10.1 in a
few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-eoan to verification-done-eoan. If it does not fix
the bug for you, please add a comment stating that, and change the tag
to verification-failed-eoan. In either case, without details of your
testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Bug description:

  I'm creating this bug report to have a place to describe the proposed

  +
  +Overview of changes in GLib 2.62.3

  +
  +* Bugs fixed:

  + - #1917 Test utf8-pointer fails with static build, LTO, optimisations, and new GCC
  + - !1174 Backport !1164 “use-after-free fix in mimeapps test” to glib-2-62

  + - !1228 Backport !1199 “gunicode: Fix UB in gutf8.c and utf8-pointer test” to glib-2-62
  +
  +
  +Overview of changes in GLib 2.62.2

  + - !1156 Backport !1146 Solaris fixes to glib-2-62

  This release can be considered to be tested under
  https://wiki.ubuntu.com/StableReleaseUpdates/GNOME

  There are patches from the upstream master branch rather than this
  stable release:

  + Add-a-test-for-GDBusServer-authentication.patch
  + gdbus-server-auth-test-Create-temporary-directory-for-Uni.patch
  + gdbus-server-auth-test-Include-gcredentialsprivate.h.patch
  + Make-ld-executable-configurable.patch

  They are sensible backports which I hope are appropriate for SRU.

  [ QA ]

  The testsuite fixes will verify themselves during the build and
  autopkgtest.

  For the rest of the fixes, please exercise the desktop thoroughly. Log
  in, log out, run many applications and make sure there are no
  regressions.

  [ Regression potential ]

  test fixes> Build failures or autopkgtest failures.

  GLib is a central desktop library. Regressions could break any part of
  the desktop - so QA is important, the SRU exception notwithstanding.
