Description
This adds a new environment flag
GATSBY_FAST_HASHING. If set, instead of cryptographically hashing files to check if they've changed, it will use a content digest comprised of the modification time and the inode. This is slightly less robust, but significantly faster especially on sites with lots of large files.This is the same as the optional feature added to
gatsby-source-filesystemhere: #37464Documentation
The flag has been added to
flags.ts. Not sure if any other web documentation would need to be added, or if it should be flagged as experimental.Tests
No tests were added because this doesn't add new functionality, it just changes how existing functionality works, so existing tests should cover it.
