computeSha1()

MediaWiki\Revision\RevisionSlots::computeSha1

(

Computes the combined hash of the revisions's slots.

Note

For backwards compatibility, the combined hash of a single slot is that slot's hash. For consistency, the combined hash of an empty set of slots is the hash of the empty string.

This is potentially expensive! It may cause all slot's content to be loaded and deserialized, then re-serialized and hashed.

Returns

string

computeSize()

MediaWiki\Revision\RevisionSlots::computeSize

(

int
