| 5 | * |
---|
| 6 | * This module creates the Tcl interface to the pymol server. It acts as |
---|
| 7 | * a go-between establishing communication between a molvisviewer widget |
---|
| 8 | * and the pymol server. The communication protocol from the molvisviewer |
---|
| 9 | * widget is the Tcl language. Commands are then relayed to the pymol |
---|
| 10 | * server. Responses from the pymol server are translated into Tcl |
---|
[1334] | 11 | * commands and send to the molvisviewer widget. For example, resulting |
---|
[2615] | 12 | * image rendered offscreen is returned as ppm-formatted image data. |

[1538] | 22 | * Notes: The proxy should not maintain any state information from the |

---|
| 24 | * atom scale, bond thickness, etc.) compression. This is because |
---|
| 25 | * the connection is periodically broken (timeout, error, etc.). |
---|
| 26 | * It's the responsibility of the client (molvisviewer) to restore |
---|
| 27 | * the settings of the previous view. The proxy is just a relay |
---|
| 28 | * between the client and the pymol server. |

---|
| 40 | * The communication between the pymol server and proxy is completely |
---|
| 41 | * synchronous. The proxy relays/translates commands from the client to the |
---|
| 42 | * server and then wait for the responses. It also watches the server's |
---|
| 43 | * stdout and stderr changes so that extraneous writes don't block the |
---|
| 44 | * the server. (I don't know exactly what those responses are) |
---|
| 45 | * |
---|
| 46 | * The communication between the client and the proxy is different. The |
---|
| 47 | * client commands are read when they become available on the socket. Proxy |
---|
| 48 | * writes to the client (image output) are non-blocking so that we don't |
---|
| 49 | * deadlock with the client. The client may be busy sending the next command |
---|
| 50 | * when we want to write the resulting image from the last command. |
