Module container_io 

The stdio of the containers and execs, pipes or a terminal, which the server reads into the log drivers, the attach clients and the output of the execs.

Modules

drain 🔒

Bounding the output which gets forwarded after the process exited.

read_loop 🔒

The read loops of the output and the stdin of the process.

stdio 🔒

The stdio channels and the collector of the output of an exec.

Structs

ContainerIO 🔒

The stdio of a container or exec, a terminal or pipes, and the log drivers and attach endpoints its output goes to.

Enums

Message 🔒

A message to be sent through the ContainerIO.

Pipe 🔒

Available pipe types.

Constants

READ_BUFFER_SIZE 🔒

The most a read of a container I/O stream takes at once. The read loops read into the scratch buffer of their thread and copy each chunk out of it, see with_scratch, so an idle container holds no read buffer. 8 KiB halves the reads and log writes of 4 KiB for bulk output, the log files start the buffer of each chunk with as much, see LogFile::BUF_CAPACITY.

STDERR_TAIL_SIZE 🔒

How much of the end of a stderr gets kept for the error of a runtime which failed, with pipes of its own or on the stderr of the process. The last lines hold the reason, a runtime with debug logging writes far more.

STDIO_CHANNEL_SIZE 🔒

How many read chunks the stdio and terminal channels buffer per pipe.

Type Aliases

SharedContainerIO 🔒

A container IO shared by its users, like the watcher, the attach endpoints and the consumer of the output of an exec.
