Typical scenario

• content of a CMS page isn’t decoupled from styles

• content of a CMS page is large and confusing

• content manager tries to change a CMS page

• the layout is destroyed

• nobody knows why

Possible solutions

Database backups

• hopefully one with the last stable content

• time consuming and complicated to restore

• has to be done by a developer

CMS pages under version control

• has every version of the content

• can be restored in seconds

• can be done by a content manager in the backend

Example - Wordpress

• it’s called revision

• every save creates a new rowin the database

• versions can be compared

• older versions can be restoredeasily

Is that possible with Magento 2?

How does diff algorithm work?

Different approaches for different purposes

• maximize matching lines

• maximize size of the biggest matching subsequence

• ...

Example - diff algorithm

from toM Me ee et tM Ma ag gn ee nt to o?

Create matrix from × to

For all i = {1, . . . , |from|} , j = {1, . . . , |to|}• ai ,j = max {ai−1,j−1, ai−1,j , ai ,j−1}• if fromi == toj and ai ,j == ai−1,j−1 then

ai ,j = ai ,j + 1

Find ADDs, REMOVE s and MATCHs

• start at ai ,j

• end at a1,1

• prefer maximum or diagonal if there is more than one maximum value

• every step• left is a ADD• top is a REMOVE• diagonal is a MATCH

for the current position
