• Spent most of this week improving postage stamp dependency checking. This part of the system manages the update processing required to regenerate images for the postage stamp server. Like most parts of PS1 this task is made quite difficult due to the requirement that images be run through magic. Deployed the enhanced code late in the week and it is now working relatively smoothly. There are still some bottlenecks that need to be tuned.
• As part of the task above, wrote a wiki page that describes how the state and data_state of IPP processed components are managed. (I needed to review the code to remember how it worked myself.)
• Added code to the IPP tools to respect a special "DO NOT REVERT" fault code, to help try and prevent update processing that cannot complete from continuing to try forever.
• Set up facility to allow IfA postage stamp users to retrieve uncensored stamps.
• Continued to monitor STS processing. Built r band reference stack. Processed the r band images. Johannes reported that some i band exposures were missing. This was likely due to premature cleanup by the operator. Reprocessed them. As of Sunday Feburary 13 all of the STS data from May through October has been processed by the IPP and delivered to the data store.
• fixed some bugs related to muggle postage stamps.
