Unable to restore arch id mappings for 'archname'

[sprout42]

When writing my own architecture plugin I always get this error when Binja starts up and as far as I can tell it should be working correctly. I've seen this error over multiple versions. This error was taken from the latest development version 3.0.3298-dev:

[Default] No bundled types for platform archname found in system types
[Default] Unable to restore arch id mappings for 'archname'
[Default] Unable to restore arch id mappings for 'archname'

What version was the original database you've loaded saved on? That error message is expected (and not an issue) if:

1. You're using a custom architecture
2. The database is from an old Binary Ninja version from about 2-3 years ago

If those apply to you, you can safely ignore the errors and you should stop seeing them if/when you upgrade that database.

If those don't apply to you, we might need to look into it further because my understanding (from looking at the relevant code) is that analysis should never head down that codepath.

no type libraries have been created for this arch

>>> bv.arch.type_libraries

And yes, I get this as soon as the GUI has opened before I open any files.

Correction! I just checked with the latest build of Binary Ninja (3.0.3301-dev) and it does not show up by default, only after opening up a database. I may have been mistaken before.

Hey, sorry, it looks like we kinda dropped this accidentally.

So, to confirm, this message shows up for you only when you open up a database that uses your custom architecture plugin? Or is it any database while your plugin is enabled? Or..?

Does it still happen on the latest version of dev (3.0.3322-dev)?

And you can confirm that, when it does show up, you have no type libraries in bv.arch.type_libraries?

I think this is probably a bug, so if you're able to confirm a bunch of those things for me, I'll go ahead and create an issue out of this discussion.

Correct, it does only show up when I open a bndb (or analyze a new binary) with my architecture plugin.

I just tested this morning on version 3.0.3329-dev.

and there are no type libraries installed
