Release Notes

Stebalien/tempfile (tempfile)

v3.18.0

Compare Source

• Update rustix to 1.0.0.
• Make NamedTempFile::persist_noclobber atomic on Apple operating systems. It's now atomic on MacOS, Windows, and Linux (depending on the OS version and filesystem used).

v3.17.1

Compare Source

• Fix build with windows-sys 0.52. Unfortunately, we have no CI for older windows-sys versions at the moment...

v3.17.0

Compare Source

• Make sure to use absolute paths in when creating unnamed temporary files (avoids a small race in the "immediate unlink" logic) and in Builder::make_in (when creating temporary files of arbitrary types).
• Prevent a theoretical crash that could (maybe) happen when a temporary file is created from a drop function run in a TLS destructor. Nobody has actually reported a case of this happening in practice and I have been unable to create this scenario in a test.
• When reseeding with getrandom, use platform (e.g., CPU) specific randomness sources where possible.
• Clarify some documentation.
• Unlink unnamed temporary files on windows immediately when possible instead of waiting for the handle to be closed. We open files with "Unix" semantics, so this is generally possible.

v3.16.0

Compare Source

• Update getrandom to 0.3.0 (thanks to @​paolobarbolini).
• Allow windows-sys versions 0.59.x in addition to 0.59.0 (thanks @​ErichDonGubler).
• Improved security documentation (thanks to @​n0toose for collaborating with me on this).

v3.15.0

Compare Source

Re-seed the per-thread RNG from system randomness when we repeatedly fail to create temporary files (#​314). This resolves a potential DoS vector (#​178) while avoiding getrandom in the common case where it's necessary. The feature is optional but enabled by default via the getrandom feature.

For libc-free builds, you'll either need to disable this feature or opt-in to a different getrandom backend.
