MySQL Bugs: #77934: mysqlpump does not dump mysql.{general_log,slow

Bug #77934	mysqlpump does not dump mysql.{general_log,slow_log} table definitions
Submitted:	4 Aug 2015 16:33	Modified:	25 Aug 2015 4:54
Reporter:	Paul DuBois	Email Updates:
Status:	Won't fix	Impact on me:	None
Category:	MySQL Server: Command-line Clients	Severity:	S3 (Non-critical)
Version:	5.7.8+	OS:	Any
Assigned to:		CPU Architecture:	Any

Description:
mysqldump has this behavior:

mysqldump includes statements to recreate the general_log and slow_query_log tables for dumps of the mysql database. Log table contents are not dumped.

(http://dev.mysql.com/doc/refman/5.7/en/mysqldump.html)

mysqlpump does not even dump the table definitions. It should.

How to repeat:
mysqlpump mysql > out

Look in output file, see that CREATE TABLE statements for general_log, slow_log are missing

Suggested fix:
Add CREATE TABLE statements for general_log, slow_log when dumping mysql database.

Hi Paul,

Thank you for the report.
Confirmed that CREATE TABLE statements for general_log, slow_log exists in dumps. Could you please confirm your build details and or any others details which would help us to reproduce this issue?

Thanks,

Thank you Paul for correcting my mistake(I was using mysqldump instead of mysqlpump for the verification). Verified as described with 5.7.8 build.

Umesh
