Changed the limit to encoded_value.len() + encoded_key.len() > 2**14
try_insert() and try_set() were ignoring that insert() and set() increase the length of the key by 4. After making the off-chain set_contract_storage() respect the size limit, this was causing some tests to fail. The tests were updated to test the correct limits.

Summary
Closes #1960
cargo-contractorpallet-contracts?Description
Issue Description
The storage in the integration environment does not have the same limitation as in the e2e environment. In the e2e environment, the storage size is limited by 16380 bytes.
Issue Documentation & Test Case
https://github.com/CoinFabrik/on-ink-integration-tests/tree/main/test-cases/set-contract-storage
Current Status
Missing Limitation Implemented. Test Cases Passed. Pull Request Performed to Corresponding Repository.
Implementation Notes
The function
set_contract_storage()sets the storage in a contract. There was a missing validation in integration tests that was present in e2e. This validation checked that the size of the storage set did not exceed 16380 bytes.We added a validation to the function
set_contract_storage()in integration tests that checks the size of the input value against the same limit set in e2e test: 16380 bytes. In case this limit is exceeded, a panic is raised with the message: "Value too large to be stored in contract storage, maximum size is {} bytes".Updated Documentation
We updated the original documentation of this issue in our repository, adding the section Update on Correcting this Issue and informing of the correction.
There is no necessary update to the associated documentation: ink_env set_contract_storage.
Testing Guide
In the directory
integration-tests/set_contract_storageof the target directory, we include in our pull request a test case showing that the observed implementation difference has been corrected. Note that this test is different from the original test case in our repository, which showed the difference.In order to run the integration tests run:
cargo testIn order to run the e2e tests run:
cargo test -–features e2e-testsThese tests are run separately because we do not need to compare their results.
