different from the number of indexes <n> defined in the MariaDB
compare_keys_but_name(): do not use KEY_PART_INFO::field for
Field::is_equal(). Following the logic of that code we need to
compare fields of a table. But KEY_PART_INFO::field sometimes
(when key part is shorter than table field) is a different field.
In that case Field::is_equal() returns incorrect result and
problems occur.
KEY_PART_INFO::field may become some strange field in
open_frm_error open_table_from_share(). I think this is an
incorrect logic, some tecnhical debt. I'm not fixing it right now,
because I don't have time. But I'm making Field::field_length
a const class member. Then, the only fishy code which changed that
field requires now a const_cast<>. I'm bringing attention to that
code with it. This change should not affect logic of the
program in any way.

FLUSH TABLE table_name"
Reverted original patch (c2e0a0b).
For consistency with "LOCK TABLE <table_name> READ" and "FLUSH TABLES
WITH READ LOCK", which are forbidden under "BACKUP STAGE", forbid "FLUSH
TABLE <table_name> FOR EXPORT" and "FLUSH TABLE <table_name> WITH READ
LOCK" as well.
It'd allow consistent fixes for problems like MDEV-18643.

The symbol SRV_MASTER_PURGE_INTERVAL became unused in
mysql/mysql-server@42f36919584e82c621dbec1e69fd05ab023c54c6
when separate purge threads were introduced in MySQL 5.6.5.

Problem:
=======
After discarding the table, fts_optimize_thread aborts during shutdown.
InnoDB fails to remove the table from fts_optimize_wq and it leads to
the fts_optimize_thread to lookup for the auxiliary table and fails.
Fix:
====
While discarding the fts table, remove the table from fts_optimize_wq.

Context involves semicolon batching, and the error starts 10.2
No reproducible examples were made yet, but TCP trace suggests
multiple packets that are "squeezed" together (e.g overlong OK packet
that has a trailer which is belongs to another packet)
Remove thd->get_stmt_da()->set_skip_flush() when processing a batch.
skip_flush stems from the COM_MULTI code, which was checked in during
10.2 (and is never used)
The fix is confirmed to work, when evaluated by bug reporter (one of them)
We never reproduced it locally, with multiple tries
thus the root cause analysis is still missing.

The column INFORMATION_SCHEMA.INNODB_MUTEXES.NAME is not populated ever since
commit 2e814d4702d71a04388386a9f591d14a35980bfe applied the InnoDB changes from
MySQL 5.7.9 to MariaDB Server 10.2.2.
Since the same commit, the view is only providing information about
rw_lock_t, not any mutexes.
For now, let us convert the source code file name and line number of
the rw_lock_t creation into a name. A better option in the future might
be to store the information somewhere where it can be looked up by
mysql_pfs_key_t, and possibly to remove the CREATE_FILE and CREATE_LINE
columns.

Do not materialize a semi-join nest if it contains a materialized derived
table /view that potentially can be subject to the split optimization.
Splitting of materialization of such nest would help, but currently there
is no code to support this technique.

fil_space_encrypt(): Remove the debug check that decrypts the
just encrypted page. We are exercising the decryption of encrypted
pages enough via --suite=encryption,mariabackup. It is a waste of
computing resources to decrypt every page immediately after encrypting it.
The redundant check had been added in
commit 2bedc3978b90bf5abe1029df393c63ced1849bed (MDEV-9931).

an object of type 'xid_count_per_binlog'
Problem:
-------
Accessing a member within 'xid_count_per_binlog' structure results in
following error when 'UBSAN' is enabled.
member access within address 0xXXX which does not point to an object of type
'xid_count_per_binlog'
Analysis:
---------
The problem appears to be that no constructor for 'xid_count_per_binlog' is
being called, and thus the vtable will not be initialized.
Fix:
---
Defined a parameterized constructor for 'xid_count_per_binlog' class.

..as they have their own tools that parses those files, such as
opensysusers[1] that handles sysusers file and opentmpfiles[2] that
handles tmpfiles.d settings
Because of this. Move both sysusers and tmpfiles 'if' function
outside systemd function, allowing independent install

[2] - https://github.com/OpenRC/opentmpfiles
Changes done by vicentiu@mariadb.org, from original author patch:
Installing sysusers and tmpfiles without checking for systemd existence
means that by default, cmake will ALWAYS install these files. Our
general policy is we do not install things which are not needed.
However, there is a valid use case when these files are useful, as is
described above.
To allow this, provide an extra switch that can be enabled during
configuring by doing -DINSTALL_SYSTEMD_{SYSUSERS|TMPFILES}=True
This will use the default path INSTALL_SYSTEMD_{SYSUSERS|TMPFILES}DIR
fetched from install_layout.cmake for rpm & deb based layouts
respectively, or they must be overriden if the install_layout is
standalone.
Example:
cmake . -DINSTALL_SYSTEMD_SYSUSERS=True -DINSTALL_SYSTEMD_SYSUSERSDIR=/etc/sysusers.d

| | | | |

| | | | |
| | | | |
| | | | | |
These files were installed to:
${INSTALL_SYSTEMD_SYSUSERSDIR}/sysusers.conf
${INSTALL_SYSTEMD_TMPFILESDIR}/tmpfiles.conf
Instead rename the files to more descriptive file names 'mariadb.conf'.
