• refactor: improve close_range() presence check on FreeBSD
• feat: read /dev/fd on iOS, just like on macOS
• Add basic example of use with a Command
• perf: on Linux, cache whether we're running on WSL 1
• perf: improve performance of slow loop fallback
• feat: add new "builders" to further customize behavior
• fix: correct getdents() link name on NetBSD
• Major internal refactors
• Improved tests and documentation

v0.3.1

Changelog:

• feat: Add support for listing /proc/self/fd on NetBSD
• feat: Add support for using close_range() on Linux 5.9+
• feat: Add support for using CLOSE_RANGE_CLOEXEC on Linux 5.11+
• feat: Add support for using close_range() on FreeBSD 12.2+

v0.3.0

Changelog:

• refactor: add "thread-safe" versions of certain functions
• perf(close): add translation step to simplify minfd/keep_fds specification
• perf(fditer): override FdIter::min() and Fditer::max() for efficiency
• ci: build for more supported targets
• feat(fditer): expose "possible" status of an FdIter
• fix: fix internal bugs
• refactor: major internal refactoring
• doc: improved documentation (and warnings)
• test: improved tests

v0.2.2

Changelog

• Remove Windows support
  • It unnecessarily complicates portions of the code, especially the testing code.
  • It may require users to set an "invalid parameter handler" for it to work properly. Most probably won't realize this and will be confused to see their programs segfault.
  • The real killer: Windows handles file descriptors differently, and a function that closes all file descriptors just isn't necessary for security on Windows.
    The way I understand it, only file descriptors 0, 1, and 2 are ever inherited across program launches. File handles are inherited by default, but we can't close them.
• Implement size_hint() for FdIter
• Add warnings to the docs of iter_open_fds() and iter_possible_fds()
• Add Solaris/Illumos support
• Ensure FdIter is fused and mark it as such
• Minor internal refactoring

v0.2.1

CHANGELOG:

• Add new (Unix-only) set_fds_cloexec() helper
• FreeBSD: Don't use the kern.proc.nfds sysctl from close_open_fds() (since closefrom() can be used to provide a performance boost on the BSDs, and kern.proc.nfds may actually slow that down)
• Internal reorganization
• Improved documentation

v0.2.0

Changelog

• Improve efficiency of close_open_fds() if keep_fds is sorted
• Add Windows support (closes file descriptors only, not file handles)
• Disable /proc/self/fd check on WSL 1, where it's broken (it works on WSL 2)
• Open all file descriptors as O_CLOEXEC (just in case)
• Make tests stricter

v0.1.0
