cl-wal is a library implementing simple write ahead log. Write ahead log maintains journal for a master file. Journal is managed with commit, rollback and recover calls. Entries to journal are added with write. The write ahead log does not define any semantics for entries but the user must provide functions for reading and writing both log and master file entries.


cl-wal is asdf-install installable. cl-wal no longer depends on cl-unit-test. See ChangeLog for details. The current release is 0.4.

In SBCL installation can be done with following commands:

(require 'asdf-install)
(asdf-install:install :cl-wal) ; or
(asdf-install:install :cl-wal-0.4) ; this has dependency to versioned cl-binary-file

ASDF-install package (obsolete)
