04aabe0921 Include the original file instead of a patch if the patch is larger than the original file.
This saves processing and disk space, as there is no point in applying a patch when the original file is smaller and can be included in its entirety.

8dd4d71d75 Significant rework of patches
- The "diff type" is now specified per file, allowing for different diff methods in each modified file.
- Patches will only be created when both the before and after files are less than 100kiB in size.
- Patches are validated after creation, and if invalid it will fall back to including the entire file.

This has identified a bug where patching fails for files without trailing newline characters, which still needs to be fixed. Until then, it will fall back to including the entire file in these cases.

0f1927b4b1 Take a hash of the previous state's directory structure and file contents, and then include that hash in the patch metadata (when creating a new patch). This allows the integrity of the layers to be validated as each one is applied. 2021-08-17 08:43:08 +01:00
