### 0.8.15 (unreleased)
|
||||
|
||||
Important Bugfixes:
|
||||
* Code Generation: Avoid writing dirty bytes to storage when copying ``bytes`` arrays.
|
||||
* Yul Optimizer: Keep all memory side-effects of inline assembly blocks.

"description": "Copying ``bytes`` arrays from memory or calldata to storage is done in chunks of 32 bytes even if the length is not a multiple of 32. Thereby, extra bytes past the end of the array may be copied from calldata or memory to storage. These dirty bytes may then become observable after a ``.push()`` without arguments to the bytes array in storage, i.e. such a push will not result in a zero value at the end of the array as expected. This bug only affects the legacy code generation pipeline, the new code generation pipeline via IR is not affected.",

- New code generator: ``0`` as all parameters, including return parameters, will be re-initialized before
|
||||
each ``_;`` evaluation.
|
||||
|
||||
- Copying ``bytes`` arrays from memory to storage is implemented in a different way.
|
||||
The old code generator always copies full words, while the new one cuts the byte
|
||||
array after its end. The old behaviour can lead to dirty data being copied after
|
||||
the end of the array (but still in the same storage slot).
|
||||
This causes differences in some contracts, for example:

(it has correct length, and correct first 8 elements, but then it contains dirty data which was set via assembly).
