Subject: Don't leak temporary file on failed multi-file ed-style patch
|
|
Git-commit: 369dcccdfa6336e5a873d6d63705cfbe04c55727
|
|
Patch-mainline: yes
|
|
References: bsc#1092500, savannah#53820
|
|
|
|
The previous fix worked fine with single-file ed-style patches, but
|
|
would still leak temporary files in the case of multi-file ed-style
|
|
patch. Fix that case as well, and extend the test case to check for
|
|
it.
|
|
|
|
* src/patch.c (main): Unlink TMPEDNAME if needed before moving to
|
|
the next file in a patch.
