Error parsing Paratext settings

[Enkidu93]

We got this error recently on ext QA:

An unhandled exception was thrown by the application.
System.ArgumentException: An item with the same key has already been added. Key: SIL.Scripture.Versification+Table+VersificationKey
at System.Collections.Generic.Dictionary`2.TryInsert(TKey key, TValue value, InsertionBehavior behavior)
at System.Collections.Generic.Dictionary`2.Add(TKey key, TValue value)
at SIL.Scripture.Versification.Table.Load(TextReader stream, String fullPath, ScrVers baseVers, String name)
at SIL.Machine.Corpora.ParatextProjectSettingsParserBase.Parse()

This is actually a bug (or not proper handling) in SIL. Scruipture, that is, https://github.com/sillsdev/libpalaso -> https://github.com/sillsdev/libpalaso/blob/master/SIL.Scripture/Versification.cs.

[Enkidu93]

OK, is this something we should try to fix there or something we need to handle more robustly in Machine itself?

@ddaspit - what do you think? Should we make a pull request to https://github.com/sillsdev/libpalaso?

[ddaspit]

Yes, we need to make a change to SIL.Scripture. Versification.Table.Implementation is a static property, and the Load method saves custom versifications to an internal dictionary. This will result in the internal dictionary filling up with custom versifications over time. We don't want or need that. We want a Load method that does not add custom versifications to the dictionary.

We've seen a few more of these errors on the rancher alerts, so maybe we should escalate this issue. It also shouldn't be terribly difficult to fix, right? And there might be a slow turnaround given that we might need to wait for approval from outside our team?

@Enkidu93 - can you make a issue (and propose a fix) on libpalaso? They are usually pretty responsive, but it still will likely take 2 weeks start to finish. Feel free to message the repo owners on slack as well.

@Enkidu93 - what is the current status of this? Do we need to use https://www.nuget.org/packages/ParatextData?

Yes, we can either use ParatextData or implement it ourself following ParatextData's implementation.

[ddaspit]

I don't want to have a dependency on ParatextData. We should be able to implement it ourselves pretty easily.
