When the last munmap(2) completes, the file will have been written to the backing storage.The native macOS file handling abilities can be extended by using third party file systems.

Perform synchronous writes when unmapping a file from memory. Using an I/O size value less than the platform's page size can cause hangs. On Apple Silicon the minimum I/O size is 16,384 bytes. Set minimum I/O size value ( iosize mount option) to the platform's page size. Improve detection of remote file changes and prevent unnecessary writes. See Unicode Normalization Forms for details. file names not being displayed in Finder under certain conditions. Using the C form can result in unexpected behavior, e.g. Improve support for non-latin languages by adding support for returning file names in the Unicode Normalization Form D (NFD) in the readdir callback.įinder and other macOS system tools expect file names to be in the D form. This triggers another scan cycle and so on.Īdd workaround for a missing TARGET_OS_OSX macro in Xcode 13's sys/cdefs.h kernel header. If such a scanner maps the file to memory, the file's modification time will get updated again as soon as the scanner calls munmap(2). This unnecessary write would update the file's modification time, which in turn might cause security software to scan the file. On Apple Silicon munmap(2) might trigger a write, regardless of whether the mapped file was modified or not. See #824 for details.Īdd workaround for an infinite write loop when unmapping a file from memory on Apple Silicon.

See #832 for details.įix race condition when removing a directory or creating a symlink. Fix race condition that can result in mkdir(2) returning EINVAL when creating multiple directories recursively.
