[PATCHv2 0/2] ch: minor fixes - segfault and last meaningful error preservation

During fixing some other issue found out a few minor bugs related to CH driver. First bug is related to monitor object ref count in virCHStartEventHandler and virCHEventHandlerLoop, as object was unrefed by parent while is still used by child thread. Moved object unref to the correct place to the correct thread. Second bug is related to v object ref count in virCHStartEventHandler, as vm object was unrefed, while is still used later, move object unref to after its last usage. Third bug is related to error handling and propagation. Last meaninful error was reset by virCHProcessStop, which have led to unknown error message in virsh. Add error preservation at the begining of the function and restoring it at the end to keep consistent error output Kirill Shchetiniuk (2): ch: virCHProcessStop preserve last meaningful error ch: ref count fix in virCHEventHandlerLoop and virCHStartEventHandler src/ch/ch_events.c | 4 ++-- src/ch/ch_process.c | 5 +++++ 2 files changed, 7 insertions(+), 2 deletions(-) -- 2.48.1
