Bug in startObservationSummaryReport - incorrectly assuming source code location

[markmac99]

Richard Bassom in the UK reports a failure on the multicam installation that seems to be due to the new functionality to create a report of station status.

At line 169, the code in startObservationSummaryReport tries to import a git repo to check the RMS version. It assumes that the the folder containing the RMS config file also contains the code. On multistation builds this is incorrect and so it fails.

The code in question seems to have been introduced into RMS about 28 days ago, and may not have been noticed by multicam users as many do not reboot frequently. 
I think we need exception handling around that section of the code and/or passing in the right folder. I'll raise an issue and perhaps someone familiar with this code could take a look?

I had a problem at the start of last night with my Ubuntu Linux PC RMS system running 3 cameras. I reverted to the previous RMS release to get it running again.
The RMS log shows the following, and the capture didn't start:

Working on this now. As a triage measure, I propose to remove the offending lines until a proper solution is found.

Make sure the XXxxxx_StartCap.desktop in the Desktop and in ~/.config/autostart is updated to:

[Desktop Entry]
Name=XXxxxx-Startcapture
Type=Application
Exec=lxterminal --title=XXxxxx -e "~/source/RMS/Scripts/MultiCamLinux/StartCapture.sh XXxxxx"
Hidden=false
NoDisplay=false
Icon=lxterminal

Can we now introduce both MCP files, as discussed earlier in the email thread?
MultiCamLinux.zip
This is the gap in master for multicam now.

These scripts have a couple of issues.

Firstly

https://github.com/g7gpr/RMS/blob/74a822bc833fc18f5ac7df16c56c08e1619c80e7/Scripts/MultiCamLinux/StartCapture.sh#L44

change directory to ~/source/Stations/STATID which causes various strange things to happen; for example RMS can run a version of code which is cached somewhere, rather than the version in ~/source/RMS

Secondly the RMS_StartCapture_MCP.sh loops through all the stations starting them at 5 second intervals. If the first station to be started has not finished any pre-run work, then two station start working on the same code. This can produce strange effects.

However, lots of stations are using them successfully.

I believe this has been handled by cdec45a

It's a quick fix that ignores the git repo part as it's not critical for observations, just for reporting.

I'm working through the multicam Linux and Pi and implementations. A lot of what we are seeing needs fixing there, not in the main code.
