Here's the first known occurrence of the MTZ problem "in the wild". I am going to downgrade to a logged warning for now, so that builds work and new users don't get bitten.

We need to discuss the issue at a programmer's meeting. The possible solutions that occur to me are:

1) Toolshed fetch is synchronous if the cache is missing, asynchronous otherwise.

2) Move the PDB-REDO MTZ fetch to a small bundle on the toolshed. Users would have to get that bundle _and_ the Clipper bundle to get the fetch to work, and the fetch would not show up in the Fetch By ID panel if the toolshed cache was not initialized.

3) Ask Tristan to add the fetch code to the Clipper bundle. Still would not show up in Fetch By ID if toolshed cache was missing.

4) Some kind of complex code that remembers these kinds of failures and reexamines them when the toolshed cache initialization completes.

Okay, downgraded the error to just a log message for now.

[Eric Pettersen]

I guess option (5) is just to leave it as a log message -- you won't be able to fetch REDO maps until you start ChimeraX with an existing toolshed cache.

Does this downgrading the error to just log a message fix the Mac Intel build which fails making the Info.plist file? If not, it would be nice to fix the Mac Intel build now possibly by removing PDB-Redo fetch until we have an adequate solution.

[Eric Pettersen]

I believe it should fix it.

And option (6)(!) is to moved the MTZ format declaration from the Clipper bundle to the map bundle (leaving the actual opener in Clipper).

Does the toolshed's API not support queries like SELECT * FROM BUNDLES WHERE PROVIDED_FILETYPES="mtz"? That would be a lightning fast query even if it was synchronous.

Perhaps we could put the toolshed cache the Webservices and have an endpoint called by something like toolshed_bundle_for_filetype()

This would be kind of like what Greg was suggesting except every ChimeraX would be up to date forever.

[Eric Pettersen]

These are both good possibilities if this kind of issue occurs more, so that it's worth the implementation effort. My plan right now for the MTZ thing is to ask the chimerax.core Toolshed instance if its cache is initialized (need a new API call for that) and if it isn't, don't even put anything in the log about the missing format, but if it is initialized then issue a warning (since the missing format is an actual problem).

Replying to Zach Pearson:
