git-tempfile

Use tempfiles to minimize the risk of resource leakage when preparing to overwrite or create a file with new content in a signal-safe way, making the change atomic.

Tempfiles can also be used as locks as only one tempfile can exist at a given path at a time.

• registered temporary files which are deleted automatically as the process terminates or on drop
  • write to temporary file and persist it under new name
  • close temporary files to convert them into a marker while saving system resources
  • mark paths with a closed temporary file
• persist temporary files to prevent them from perishing.
• signal-handler integration with gix to clean lockfiles before the process is aborted.
• use a temporary file transparently due thanks to implementations of std::io traits
