1.3.2 Process Flow: Bitcoin and Bitseed Configuration Reads

Reads correspond to values being read out of the Bitcoin and Bitseed configuration files and written to the UI. The steps that are taken to perform a read operation are shown below in the order that they occur. These steps are also indicated in Figure 1.9 below.

1. On any page load event, www_rd_bconf_request.php is invoked.
2. www_rd_bconf_request.php issues a read request by writing a ‘1’ to rd_bconf_flag. It then begins polling for a ‘2’ in the rd_bconf_flag file every 5 seconds.
3. lin_rd_bconf_launch. py is run every 5 seconds and samples rd_bconf_flag.
4. If a ‘1’ is detected, lin_rd_launch.py runs lin_rd_bconf_mbox.py.
5. lin_rd_bconf_mbox.py reads the parameters of interest out of the Bitcoin and Bitseed configuration files.
6. lin_rd_bconf_mbox.py writes these values as a JSON object to rd_bconf_mbox.
7. lin_rd_bconf_mbox.py write a ‘2’ to rd_bconf_flag.
8. www_rd_bconf_request detects the value ‘2’ in rd_bconf_flag.
9. Upon detection, www_rd_bconf_request.php will read out the contents of rd_bconf_mbox.
10. www_rd_bconf_request.php writes the values from rd_bconf_mbox to the UI.
11. www_rd_bconf_request.php writes a ‘0’ to rd_rd_bconf_flag which marks the end if this operation.
