langchain[patch]: Fix: Prevent text-splitter `createDocments` metadata being overwritten. #4350

iperzic · 2024-02-09T10:30:46Z

This PR fixes a potential issue with text-splitter when createDocuments is called with an empty array for metadata.

If the metadatas argument is an empty array, it should be populated with an empty object. The previous logic was using fill to fill all array positions with the same object reference. If that object was to modify, it will be applied to every array element. Luckily, it was not noticeable because spread operator is being used.

This change guarantees that every element will have a unique object, thus preventing nasty object reference bugs.

Nice catch, thank you!

jacoblee93 · 2024-02-09T23:07:39Z

Can you run yarn test? It's breaking our text splitter test.

Array constructor simpy creates and array with empty slots, which are not the same as slots filled with the value undefined. To populate the array with placeholder values, we fill with `null`, which will get overwritten in subsequent `map` with new objects

Sorry about that, I naïvely thought that I could get by without cloning the repo, so I missed the eslint error.

Should be good to go now ™️
