twpl 0.1.1

Two-phase locking via lockfiles

Two-phase locking with lockfiles

• Initial release
• Currently supports Linux/POSIX only
• Documentation coming soon

Relies on modifying the number of open file descriptors for a lockfile.

Currently implements the 2PL lock compatibility table:

Lock type	read-lock	write-lock
read-lock	Y	N
write-lock	N	N

Read locks are called "concurrent," and write locks are called "exclusive."

The API, the naming, and the implementation are all subjects to change until the first stable release (i.e. until version 1.0.0, or earlier if explicitly stated).
