[Libguestfs] [PATCH v2 2/4] common/mltools: make sure machine readable output is flushed

Enhance the helper printf function for machine readable output to always flush after each string: this way, readers of the machine readable stream can get the output as soon as it is outputted. --- common/mltools/tools_utils.ml | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/common/mltools/tools_utils.ml b/common/mltools/tools_utils.ml index 5a35708cd..ade4cb37f 100644 --- a/common/mltools/tools_utils.ml +++ b/common/mltools/tools_utils.ml @@ -59,7 +59,11 @@ let machine_readable () = | None -> None | Some chan -> let pr fs = - ksprintf (output_string chan) fs + let out s = + output_string chan s; + flush chan + in + ksprintf out fs in Some { pr } -- 2.20.1
