MySQL Bugs: #90889: Performance Reports error with MySQL Server 8.0.11

Bug #90889	Performance Reports error with MySQL Server 8.0.11
Submitted:	16 May 2018 14:38	Modified:	29 May 2018 17:35
Reporter:	Ben Williams	Email Updates:
Status:	Closed	Impact on me:	None
Category:	MySQL Workbench: Administration	Severity:	S2 (Serious)
Version:	8.0.11	OS:	Ubuntu (Ubuntu 18.04 LTS)
Assigned to:		CPU Architecture:	x86

Description:
When connected to a MySQL 8.0.11 server, Workbench shows an error when accessing the Performance Reports or Performance Schema Setup screens.

The error reads:

"Unable to access Performance Schema helper (sys)

set_error_message() takes exactly 2 arguments (3 given)"

In the debug log file I see this error:

10:29:12 [ERR][wb_admin_perfschema.py:validate:394]: Error checking for PS helper: Traceback (most recent call last):
  File "/usr/lib/mysql-workbench/modules/wb_admin_perfschema.py", line 381, in validate
    self.set_error_message("Installed Performance Schema helper (sys) version is newer than supported", "MySQL Workbench needs to downgrade it.\n(current version is %s, server has %s).%s" % (curversion, installed_version, install_text))
TypeError: set_error_message() takes exactly 2 arguments (3 given)

How to repeat:
1. Connect to a MySQL 8.0.11 server
2. Click on "Performance Reports" or "Performance Schema Setup"

Fixed as of the upcoming MySQL Workbench 8.0.12 release, and here's the changelog entry:

With an active MySQL 8.0.11 server connection, MySQL Workbench displayed
an error message when a valid attempt was made to open Performance Reports
or Performance Schema Setup.

Thank you for the bug report.
