README

        
* WHAT

  echoev is a simple TCP echo server, built on libev. It has several

  options; run 'echoev --help' for usage.

  echoevc is a simple TCP echo client, also built on libev. It, too,

  has several options; run 'echoevc --help' for usage.

* WHY

  I wrote echoev and echoevc to get some experience with libev.

* INSTALLING

  1. In the Makefile, uncomment the PLATFORM define for your platform.

  2. Set the INCLUDES and LIBS Makefile variables to point to your

     libev install, if it's in a non-standard location.

  3. make

* BUGS/LIMITATIONS

  - The server uses a per-connection ring buffer to prevent clients

    from DOSing the host (e.g., by writing an endless stream of bytes

    to the server without ever reading any of them back). The ring

    buffer capacity is 8192 bytes, so the client cannot have more than

    8192 bytes outstanding to be read from the server, nor can it

    write a single line greater than 8192 bytes. If the client exceeds

    its buffer size, the server will unceremoniously close the

    connection.

  - The client also uses a ring buffer (for convenience, not for any

    kind of security). Its buffer capacity is 32KiB. The client will

    do what it can to prevent the buffer from overflowing, but the

    buffer size does limit the maximum line size that can be sent to

    the server.
