PMPS UI Fixes and Updates

We had a few fixes and feature updates for the PMPS UI diagnostic tool in July.

• Fixed a bug where the rate and transmission readbacks on the line beam parameters page were showing the live totals instead of the controlled readback value, causing some confusion.
• Add a default "Beam Permitted: False" filter on the fast faults page. This makes the GUI load slightly faster because it doesn't have to render all the fast fault widgets on load, and it lets us get to the most important view first.
• Disable the grafana web views for now, these are causing crashes on operator consoles.
• Rearrange the "Arbiter Outputs" page that was previously difficult to see which status was connected to which PLC.

Hutch Python and Conda Updates

The following environments were released during May, June, and July:

• PCDS Conda Release Notes: pcds-5.4.0
• PCDS Conda Release Notes: pcds-5.4.1

pcds-5.4.2 is planned to be released shortly, at the end of July or at the start of August. This is planned to be the first update with "gentler" dependency updates to minimize the potential for picking up unexpected behavior on update.

Note that any applications using pcds-5.3.1 should update if they plan to use hutch-python in an experiment setting. There is a bug in this version that can lead to dangerous results where the history of separate ipython sessions will get mixed during execution, so someone else's "move" command can end up in your history and it is very very easy to accidentally run their command instead of re-running yours.

Python Performance Project (Ongoing)

We've been working on tracking down the reasons why various Python apps are slow to load and trying to minimize the parts we can control. To this end, we've already found a bunch of speed ups and work is ongoing. Some of these are tricky because, while startup speed is important, having a design tradeoff that adds slowness later can be just as bad.

A project page is opened here and work is ongoing: Hutch Python/Lightpath Device Loading Slowdown Findings/Fixes
