void kzh::delete_operation::commit ( )

virtual

Purging is handy for operations that use the Karazeh cache while deploying or staging. When an operation is called to commit, it is guaranteed that the patch has been rolled out successfully and any transient data will not be needed (no rollback will be invoked).

The cache is used for operations that require storing some data in a safe place only for the use of rollbacks if required, but should otherwise be discarded.

Reimplemented from kzh::operation.

References kzh::operation::config_, kzh::KARAZEH_EXPORT::file_manager, and kzh::file_manager::remove_file().

STAGE_RC kzh::delete_operation::deploy ( )

virtual

Moves the file or directory at a given path to Karazeh's cache. The entry is purged from the cache if the patch was successful (no rollback required).

Implements kzh::operation.
