Module shared

This module implements a shared file with access controlled by an “advisory lock”. It allows multiple read access while restricts write access to a single actor at any given time.

This lock can be used to coordinate access to the file but should not be used as a mean to guarantee security restrictions to t

Structs

DefaultSharedFileLockNameBuilder

This is the default implementation of the SharedFileLockNameBuilder.

SharedDirectory

This struct implements an “advisory lock” of a directory by using an auxiliary lock file to control the shared read access to it.

SharedDirectoryReadLockGuard

An RAII implementation of an “advisory lock” of a shared read to the protected directory. When this structure is dropped (falls out of scope), the shared read lock is released.

SharedDirectoryWriteLockGuard

An RAII implementation of an “advisory lock” of a exclusive read and write to the protected directory. When this structure is dropped (falls out of scope), the shared read lock is released.

SharedFile

This struct implements an “advisory lock” of a file using an auxiliary lock file to control the shared read access to the file as well as an exclusive read and write access to it.

SharedFileReadLockGuard

An RAII implementation of an “advisory lock” of a shared read to the protected file. When this structure is dropped (falls out of scope), the shared read lock is released.

SharedFileWriteLockGuard

An RAII implementation of an “advisory lock” of a exclusive read and write to the protected file. When this structure is dropped (falls out of scope), the shared read lock is released.
