This feature adds the support for rr in mtr. These 2 options are added
--rr run the mysqld in rr record mode
--rr_option= run the rr with custom record option, for multiple options use --rr_option= for each option.
For example
./mtr main.view --rr_option=-h --rr_option=-u --rr_option=-c=23
--boot-rr run the mysqld performing bootstrap in rr record mode
Recording are stored in mysql-test/var/rr folder.
To run recording please run
rr replay var/rr/mysql-X
Limitations
Restart will create a new recording.
Repeat will work on same recording , So might be harder to debug.
If test create the multiple instance of mariadb all will be stored in var/rr
MDEV-21549 IMPORT TABLESPACE fails to adjust all tablespace ID in root pages
After MDEV-12353, the consistency check that I originally added for
commit 1b9fe0bbac72d49a32863241b2b5081438b5f691
(InnoDB Plugin for MySQL 5.1) started randomly failing.
It turns out that the IMPORT TABLESPACE code was always incorrect:
it did not update the (redundantly stored) tablespace ID
in index tree root pages. It only does that for page headers
and BLOB pointers.
PageConverter::update_index_page(): Update the tablespace ID
in the BTR_SEG_TOP and BTR_SEG_LEAF of index root pages.
This is a backport of commit b8b3edff1376dc68c13d819470edfb33c339a64b.
mbstream: Remove duplicate definition of datasink_buffer
For some reason, when mbstream is compiled with GCC 10,
ld will fail to link it due to a multiple definition of
datasink_buffer. The code appears to have been like that
since the very beginning.
