From 21f396de6f5024abbf6edd2ca63edcb1525eefcc Mon Sep 17 00:00:00 2001 From: Nalin Dahyabhai Date: Thu, 19 Aug 2021 18:24:47 -0400 Subject: logs: adjust handling around partial log messages In libpod/logs.LogLine.Write(), don't write a newline to stdout/stderr when the log message is only part of a line. In libpod.ConmonOCIRuntime.HTTPAttach(), don't send a newline over the HTTP connection when the log message is only part of a line. In pkg/api/handlers/compat.LogsFromContainer(), don't send a newline over the HTTP connection when the log message is only part of a line, and don't make doing so conditional on whether or not the client used the docker or podman endpoint. In pkg/domain/infra/tunnel.ContainerEngine.ContainerLogs(), don't add our own newline to log messages, since they already come through from the server when they need to.
