Compare Source

Significant refactor of copy() & copySync(), including breaking changes. No changes to other functions in this release.

Huge thanks to @​manidlou for doing most of the work on this release.

• The filter option can no longer be a RegExp (must be a function). This was deprecated since fs-extra v1.0.0. #​512
• copy()'s filter option can now be a function that returns a Promise. #​518
• copy() & copySync() now use fs.copyFile()/fs.copyFileSync() in environments that support it (currently Node 8.5.0+). Older Node versions still get the old implementation. #​505
• Don't allow copying a directory into itself. #​83
• Handle copying between identical files. #​198
• Error out when copying an empty folder to a path that already exists. #​464
• Don't create dest's parent if the filter function aborts the copy() operation. #​517
• Fix writeStream not being closed if there was an error in copy(). #​516
