Backport pull request #125 from grooverdan/MDEV-8923_innodb_buffer_pool_dump_pct to 10.0
WL#6504 InnoDB buffer pool dump/load enchantments
This patch consists of two parts:
1. Dump only the hottest N% of the buffer pool(s)
2. Prevent hogging the server duing BP load
From MySQL - commit b409342c43ce2edb68807100a77001367c7e6b8e
Add testcases for innodb_buffer_pool_dump_pct_basic.
Part of the code authored by Daniel Black
As galera node (slave) received query log events from an async
replication master, it partially wrote the updates made to replication
state table (mysql.gtid_slave_pos) to galera transaction writeset post
TOI. As a result, the transaction handle, thus created within galera,
was never freed/purged as the corresponding trx did not commit.
Thus, it kept piling up for every query log event and was only reclaimed
upon server shutdown when the transaction map object got destructed.
Fixed by making sure that updates in replication slave state table
are not written to galera transaction writeset and thus, not replicated
to other nodes.
that was mistakenly merged from mysql-5.5.47
(introduces valgrind failures in main.sp, because Field_varstring
columns are created as FIELD_NORMAL and that causes aria to
read bytes between the actual value length and field max length)
Make dependency on mysql-common package in debian/control
versioned to force that it is installed together with the other
mariadb-* packages. This ensures that the init.d and systemd
files for MariaDB mysqld are the ones from MariaDB.org repos.
This is useful for developers who run autobake-deb.sh directly
from the source tree as the resulting source tar package will be
90% smaller and all operations regarding it consequently 10x faster.
This should make the provides/breaks/replaces/conflicts lines
work properly when upgrading from mysql-5.6 to mariadb-packages.
Conflicts:
debian/control
The only difference between the files was the Debian standards
line by one micro version. There was no logical motivation why
there was separate control file for Debian and Ubuntu.
The new debian/control file lives directly at the correct location
and has the correct contents.
Modify autobake.sh to take into account new control file location.
while according to Storage Engine API column names should be compared
case insensitively. This can cause FRM and InnoDB data dictionary to
go out of sync.
OPTIMIZE TABLE against MyISAM/Aria table may fail and leave stale temporary file
if mysql_file_create() returns 0 file descriptor. This was due to wrong
condition, which considered 0 as failure.
5.5 doesn't have fix for MDEV-5679, thus 0 file descriptor is always occupied
by stdin and this bug is not reproducible.
10.1 has fix for MDEV-8475, which hides this bug.
No test case since it mostly depends on how OS returns file descriptors.
Called thd_progress_init() from several threads used for FT-index
creation. For FT-indexes, need better way to report progress,
remove current one for them.
