Title:
glib apps using GSubprocess communicate might crash on
g_subprocess_communicate_cancelled
Status in glib2.0 package in Ubuntu:
Fix Released
Status in glib2.0 source package in Bionic:
In Progress
Bug description:
[ Impact ]
Glib apps using subprocess communicate and cancellable is cancelled
crashes
[ Test case ]
Run the attached example with
gjs subprocess-cancelled.js
Should not crash, or running:
valgrind gjs subprocess-cancelled.js
should not return any read error (as the one mentioned below)
[ Regression potential ]
Really low, the only thing that could happen is that the subprocess
isn't really cancelled.
