Subject: Abort when cleaning up fails
|
|
Patch-mainline: Yes
|
|
Git-commit: b7b028a77bd855f6f56b17c8837fc1cca77b469d
|
|
References: boo#1111572 savannah#54845

When a fatal error triggers during cleanup, another attempt will be made to
|
|
clean up, which will likely lead to the same fatal error. So instead, bail out
|
|
when that happens.
|
|
src/patch.c (cleanup): Bail out when called recursively.
|
|
(main): There is no need to call output_files() before cleanup() as cleanup()
|
|
already does that.
