From 1dcb771dbd63e7ee883e400da4a8e3295cfb6666 Mon Sep 17 00:00:00 2001 From: Peter Hunt Date: Thu, 12 Sep 2019 16:06:44 -0400 Subject: exec: Register resize func a bit later if we register the resize func too early, it attempts to read from the 'ctl' file before it exists. this causes the func to error, and the resize to not go through. Fix this by registering resize func later for conmon. This, along with a conmon fix, will allow exec to know the terminal size at startup Signed-off-by: Peter Hunt --- libpod/oci_attach_linux.go | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) (limited to 'libpod/oci_attach_linux.go') diff --git a/libpod/oci_attach_linux.go b/libpod/oci_attach_linux.go index 22afa7416..6cada0801 100644 --- a/libpod/oci_attach_linux.go +++ b/libpod/oci_attach_linux.go @@ -107,8 +107,6 @@ func (c *Container) attachToExec(streams *AttachStreams, keys string, resize <-c logrus.Debugf("Attaching to container %s exec session %s", c.ID(), sessionID) - registerResizeFunc(resize, c.execBundlePath(sessionID)) - // set up the socket path, such that it is the correct length and location for exec socketPath := buildSocketPath(c.execAttachSocketPath(sessionID)) @@ -116,6 +114,7 @@ func (c *Container) attachToExec(streams *AttachStreams, keys string, resize <-c if _, err := readConmonPipeData(attachFd, ""); err != nil { return err } + // 2: then attach conn, err := net.DialUnix("unixpacket", nil, &net.UnixAddr{Name: socketPath, Net: "unixpacket"}) if err != nil { @@ -127,6 +126,10 @@ func (c *Container) attachToExec(streams *AttachStreams, keys string, resize <-c } }() + // Register the resize func after we've read the attach socket, as we know at this point the + // 'ctl' file has been created in conmon + registerResizeFunc(resize, c.execBundlePath(sessionID)) + // start listening on stdio of the process receiveStdoutError, stdinDone := setupStdioChannels(streams, conn, detachKeys) -- cgit v1.2.3-54-g00ecf
