Bug Description

[ Description ]

The third stable release in the 2.56 series.

[ QA ]

Upstream release, so QA already performed by maintainers

https://wiki.ubuntu.com/StableReleaseUpdates/GNOME

This upload will trigger many autopkgtests that we expect to not be regressed by this upload.

[ Regression potential ]

Various fixes in multiple places so multiple apps could be affected.

  * New upstream release (LP: #xxx)
    + The documentation for G_GNUC_MALLOC has changed to be more restrictive
      to avoid miscompilations; you should check whether any uses of it in
      your code are appropriate
    + Fix cancellation of g_subprocess_communicate_async() calls
    + Bug fixes:
      + /network-monitor/create-in-thread fails in (LXC) containers on glib-2-56
      + GBookmarkFile: nullptr access in current_element
      + GBookmarkFile: heap-buffer-overflow in g_utf8_get_char
      + Backport g_subprocess_communicate() cancellation fixes from !266 to
        glib-2-56 (LP: #1789476)
      + Many uses of G_GNUC_MALLOC are incorrect
      + Test for BROKEN_IP_MREQ_SOURCE_STRUCT is broken on Windows / Mingw
      + Fix persistent CI failure on glib-2-56

What testing will be done of the resulting binary packages to guard against misbuilds not caught by the upstream testing? Please call this out explicitly in the bug description. (If the autopkgtests are sufficient, that's fine, please just call it out.)

This upload should *fix* misbuilds for future builds. It itself shouldn't cause things to break and/or unbreak (unless there was breakage inside glib2.0 itself, in which cause I would have expected one or more of the rdeps' tests to have picked the problem up already).

On the upstream issue that resulted in that particular fix somebody came up with a reproducer, but upstream we are not aware of any cases in the wild where anything was tripping over this. (Not that we would necessarily be, of course.)

I've added a note to watch out for the autopkgtests that'll be triggered by this upload. As I say though, I would have expected that if this bug was breaking applications then we'd already have known about it by failing tests or bug reports.

Hello Iain, or anyone else affected,

Accepted glib2.0 into bionic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/glib2.0/2.56.3-0ubuntu0.18.04.1 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-bionic to verification-done-bionic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-bionic. 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.
