Re: [libvirt] [PATCH 1/2] command: handle empty buffer argument correctly

virBufferContentAndReset (intentionally) returns NULL for a buffer with no content, but it is feasible to invoke a command with an explicit empty string. * src/util/command.c (virCommandAddEnvBuffer): Reject empty string. (virCommandAddArgBuffer): Allow explicit empty argument. * tests/commandtest.c (test9): Test it. * tests/commanddata/test9.log: Adjust. --- src/util/command.c | 13 ++++++++++++- tests/commanddata/test9.log | 4 +++- tests/commandtest.c | 13 ++++++++++++- 3 files changed, 27 insertions(+), 3 deletions(-)
