• Submitted: 22 Jan 10:24
• Modified: 30 Jan 15:02

Description:
1. default deactivation of classic_hashing is a breaking change and should be mentioned under Functionality Added or Changed (not just under Security notes).

2. https://dev.mysql.com/doc/refman/9.6/en/legacy-hashing-component.html
URN: file://classic_hashing
is wrong (at least in ubuntu build), URN is component_classic_hashing
INSTALL COMPONENT 'file://component_classic_hashing';

additional suggestion:
https://dev.mysql.com/doc/refman/9.6/en/component-loading.html
should mention that component loading is server local (not replicated).

How to repeat:
upgraded from mysql 9.5.0 to 9.6.0, the classic_hashing component is not activated.
SELECT * FROM mysql.component;
SELECT MD5('test component');

expected behavior:
- install component by default, show startup warning and change default in next version
- or clearly warn in release notes

unclear if this component is deprecated

Thank you for the report.

1. default deactivation of classic_hashing is a breaking change and should be mentioned under Functionality Added or Changed (not just under Security notes).

Release note has the important change tag added. No further updates required. 

2. https://dev.mysql.com/doc/refman/9.6/en/legacy-hashing-component.html

URN: file://classic_hashing
is wrong (at least in ubuntu build), URN is component_classic_hashing
INSTALL COMPONENT 'file://component_classic_hashing';

Updated name of component: https://dev.mysql.com/doc/refman/9.6/en/legacy-hashing-component.html

additional suggestion:
https://dev.mysql.com/doc/refman/9.6/en/component-loading.html

should mention that component loading is server local (not replicated).

Added sentence: Components are loaded in the server locally (not replicated).
