lucid's Issues

Logging setup incorrect

lucid/lucid/launcher.py

Lines 143 to 149 in b8dcaa9

    
           lucid_logger = logging.getLogger('') 
        
           handler = logging.StreamHandler() 
        
           formatter = logging.Formatter( 
        
               '[%(asctime)s] [%(levelname)-8s] - %(message)s') 
        
           handler.setFormatter(formatter) 
        
           lucid_logger.addHandler(handler) 
        
           lucid_logger.setLevel(log_level)

I don't think we should be adding a handler to the root logger here...

Lucid displays poorly on small screens

If the grid is larger than the screen height, you can't navigate to the Quick Launcher Toolbar on some setups. This can also be a problem for the device windows that open up to the right if the screen is not wide enough.

Lucid Window Title

From Silke on slack chat:
"The lucid screens should get more specific titles than "LUCID", e.g. including the beamline/hutch."

Main window: grid view on a pyqtads "central widget"?

Perhaps using this pattern: githubuser0xFFFF/Qt-Advanced-Docking-System#233 (comment)

Not really a central widget, but the splitter pattern could work well.

Seems to maybe be what we're after...

</half-baked thought>

Stale results in cached search

Refresh button
Search again after a certain period?
FIFO cache needed for search model dictionary

Some other method for results to invalidate the cache? e.g., happi update signal -> invalidate happi results cache, new dock widget -> invalidate screen cache, etc.

Embedded display intermittent issue (`object of type 'NoneType' has no len()`)

While loading the attenuator calculator screen (and maybe popping it out too quickly?)

Swap left/right click in grid

Left click
- Menu pops up with options
  - Open all
  - ----------- (spacer)
  - Device 1
  - Device 2
  - etc...
Right click either opens all or does nothing

Update happi device cache periodically

Rate limit searches to lessen CPU load

Not based on benchmarks - but perhaps a single background search thread would be more performant.

Rework the config to allow button column specification

The buttons above and below each other in the column are often cognitively linked. This is because you see multiple buttons in a column at the same time at a glance, since the buttons are wider than they are tall (due to normal horizontal text). Unfortunately, these are actually separated by several many lines in the config file, due to the way we currently fill the columns (left to right, top to bottom, in order). So if there are a subset of buttons in a tab that are meant to be related to each other, it is confusing to arrange them in a coherent way.

The current schema is "here's a number of columns, here's my buttons, please lay them out for me"
I'd like to change it to "here's the contents of column 1, here's the contents of column 2, ..."

Inactive Happi Entries Still Displayed

When marking a device as inactive in Happi, the device should no longer appear in the LUCID screen. This appears to not be the case. See an example below.

Mechanism for devices to opt out of grid placement

(From a discussion with @ZLLentz)

Name-based convention? e.g., hide devices that start with _
Happi item metadata key? e.g., "hide_from_lucid_grid: True"
Remove row/col values (stand=None) -> but this removes useful information

A variety metadata tag would make sense here, but they apply only to components.

Search: Don't highlight empty cells on grid

Open lfe... search for Energy Monitors... see that the empty cells are highlighted.

DOCS

We need docs...

Remember to:

remove at the .travis.yml the allow failures for "Docs Build" and "Docs Upload"
add the doctr deploy key

Show error if no devices found

This implies that the user did something wrong while launching the program. Here we can check for invalid beamline arguments, unset happi configs, etc.

This happened to Raj and I when we did lucid lfe and it took an embarrassingly long amount of time to figure out what happened

Setpoint vs readback fields always the same for motors

I have found that for lucid, the read back .RBV field for motors always agrees with it's set point .VAL. After an IOC reset, both are correct as the initial .VAL field is set to the current motor position and the .RBV agrees, but position fluctuations then throw the .RBV off, while lucid shows it continues to match .VAL, even after move requests. This is not the case for non-motor pytmc generated PVs, such as gantry_y or gantry_x for devices mr1l0_lfe and mr2l0_lfe.

Steps to reproduce:

$ camonitor MR2L0:LFE:MMS:PITCH.RBV

Search doesn't work on LCLS linux hosts

As I try to type "im1" for example in the search bar, the focus gets lost and my typing is interrupted. When I click back to the box I get no search results. The highlighted circles appear when I've only got "i" typed in the search bar, but disappear at "im". When they've appeared, the circles are off-center.

This behavior was observed on psbuild-rhel7 and lfe-console

Improve tests

As noted by @klauer in #93, the current tests are not adequate to make sure this package works as intended.
This includes at least the happy search algorithm but likely other areas as well.

Add gather window option

All floating windows should go back to the main screen, in tabs on the right, for example

Add excepthooks to ensure the launcher doesn't crash

sys.excepthook, threading.excepthook, ...

Could use raise_to_user to show exception, or just dump it in the console.

TypeError on startup

Opening kfe lucid screen using dev environment:

Release on conda

Ref pcdshub/pcds-envs#102

Imagers show as OK in the grid with the server offline

Might need tweaks in pcdsdevices for the imager classes, might need grid tweaks for the typhos alarm circle settings. Currently, having all the area detector PVs as "disconnected" gives us a happy green in the grid.

Columns and Rows not Sorted

Runtime Error Connection Deleted

Sometimes we get this pop up in the control room:

RuntimeError: wrapped C/C++ object of type Connection has been deleted

Sometimes the screen crashes, sometimes it happily continues on

Bug report dialog + exception logging

Include screenshot
Log entry with bug report

Uncaught exceptions -> pcds-wide logger

Style sheets usage from the lucid grid vs as-launched from related displays

Loading up the BTPS screen from las (${EPICS_SETUP}/lucid-launcher.sh LAS), and popping it out results in this awful looking display:

Whereas the configuration editor loads up without the typhos stylesheet via the PyDM related display widget, which looks roughly as it was designed:

Not sure of a really appropriate fix here, but some reactionary thoughts follow:

The typhos stylesheet remains ugly
Maybe an opt-out mechanism for the typhos stylesheet somehow?

Force beamline to be all caps

After https://github.com/pcdshub/happi/issues/100, accept inputs like:
lucid lfe
And internally change lfe to LFE

Raj and I were stuck on this for a bit

CLI seems slow

Just trying a simple lucid -h takes 5s to complete.

lfe-console:~ >source /reg/g/pcds/pyps/conda/dev_conda
lfe-console:~ >lucid -h

Xforwarding is enabled.

Main window geometry not restored (saved?) correctly

New typhos suite will not show top-level device

Click:

Then get:

I think this is preferable to the old behavior of showing the first device, in which case this is not an issue. Thoughts?

Include Alarm-aware Device Widgets in Grid (once existing)

See pcdshub/typhos#134

It'd be very useful if the grid displayed alarm colors per device.

Add a search for buttons in the tab widgets

We already have a reasonable index source of these using the yaml config. It'd be nice if there was a special "search tab" with duplicates of every button that would show/hide themselves based on the search, or some other way to quickly locate buttons in the tab maze by keyword.

Toolbar disappears after right click + deselecting an empty context menu item

Package name overlaps with tensorflow/lucid

https://pypi.org/project/lucid/#description

Using noMachine, The LFE screen partially loads.

The screen partially loads when I go through psnxserv then psdev then xpp-control.

Revisit fuzzy-finding methodology

It started out as a simple fuzzywuzzy.fuzz.ratio(s1, s2) and morphed into something uglier after realizing that partial matches on long strings would not yield any results.

Statistics could be used to threshold the fuzz ratio instead of using the absolute method in place now. Would need more filtering/limiting to keep truly insignificant results out of the mix.

I'm up for suggestions, in any case...
