… query graphs This PR addresses issues with handling fragments when they specify directive conditions: * when exploding the types we were not propagating directive conditions * when processing fragment that specifies super type of an existing type and also specifies directive condition, we were incorrectly preserving the unnecessary type condition. This type condition was problematic as it could be referecing types from supergraph that were not available in the local schema. Instead, we now drop the redundant type condition and only preserve the directives (if specified). Related: * fixes #2862 * supersedes #2864

Maybe a dumb question, but how do we restrict the types that the directive can be assigned to in the query? I assume the answer is "you can't"

AFAIK you can only specify the locations so you cannot restrict it by types. Guessing you would need some external linter/validation logic to enforce it by type.

In some cases, we will generate a lot of possible paths to access a field. There is a process to remove redundant paths, but when the list is too large, that process gets very expensive. To prevent that, we introduce an optional limit that will reject the query if too many paths are generated ([#2880](#2880)) - Updated dependencies \[[`7b5b836d15247c997712a47847f603aa5887312e`](7b5b836), [`74ca7dd617927a20d79b824851f7651ef3c40a4e`](74ca7dd), [`3f7392b84f8b626b248b59ce81f193d0f0272045`](3f7392b)]: - @apollo/[email protected] - @apollo/[email protected] ## @apollo/[email protected] ### Patch Changes - Updated dependencies \[[`7b5b836d15247c997712a47847f603aa5887312e`](7b5b836), [`74ca7dd617927a20d79b824851f7651ef3c40a4e`](74ca7dd)]: - @apollo/[email protected] ## [email protected] Co-authored-by: github-actions[bot] <github-actions[bot]@users.noreply.github.com>
