Fixed a bug introduced in MDEV-11345, server did not start if
non-english error messages were set in startup parameters.
Added lc_messages=de_DE option into an existing test case.
Variable `wsrep_new_cluster` should be set to false after `wsrep_init_startup`.
Problem was that this was done before when mysqldump is used as SST method so option
wsrep-new-cluster didn't have any effect.
Support for galera GTID consistency thru cluster. All nodes in cluster
should have same GTID for replicated events which are originating from cluster.
Cluster originating commands need to contain sequential WSREP GTID seqno
Ignore manual setting of gtid_seq_no=X.
In master-slave scenario where master is non galera node replicated GTID is
replicated and is preserved in all nodes.
To have this - domain_id, server_id and seqnos should be same on all nodes.
Node which bootstraps the cluster, to achieve this, sends domain_id and
server_id to other nodes and this combination is used to write GTID for events
that are replicated inside cluster.
Cluster nodes that are executing non replicated events are going to have different
GTID than replicated ones, difference will be visible in domain part of gtid.
With wsrep_gtid_domain_id you can set domain_id for WSREP cluster.
Functions WSREP_LAST_WRITTEN_GTID, WSREP_LAST_SEEN_GTID and
WSREP_SYNC_WAIT_UPTO_GTID now works with "native" GTID format.
Fixed galera tests to reflect this chances.
Add variable to manually update WSREP GTID seqno in cluster
Add variable to manipulate and change WSREP GTID seqno. Next command
originating from cluster and on same thread will have set seqno and
cluster should change their internal counter to it's value.
Behavior is same as using @@gtid_seq_no for non WSREP transaction.
Starting with commit 373443903b
we would invoke memcmp() unconditionally, even if the length is zero.
But, a call to memcmp() is undefined if any parameter is a null pointer,
even if the length is zero.
In the following tests, a null pointer is being passed to the comparison:
vcol.vcol_keys_innodb gcol.gcol_keys_innodb main.func_group_innodb

cmp_data(): Keep WITH_UBSAN happy and avoid potential future bugs
in optimized builds, like the one addressed by
commit fc168c3a5e (MDEV-15587).
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.
InnoDB crash recovery used a special type of mem_heap_t that
allocates backing store from the buffer pool. That incurred
a significant overhead, leading to underutilization of memory,
and limiting the maximum contiguous allocated size of a log record.
recv_sys_t::blocks: A linked list of buf_block_t that are allocated
by buf_block_alloc() for redo log records. Replaces recv_sys_t::heap.
We repurpose buf_block_t::unzip_LRU for linking the elements.
recv_sys_t::max_log_blocks: Renamed from recv_n_pool_free_frames.
recv_sys_t::max_blocks(): Accessor for max_log_blocks.
recv_sys_t::alloc(): Allocate memory from the current recv_sys_t::blocks
element, or allocate another block. In debug builds, various free()
member functions must be invoked, because we repurpose
buf_page_t::buf_fix_count for tracking allocations.
recv_sys_t::free_corrupted_page(): Renamed from recv_recover_corrupt_page()
recv_sys_t::is_memory_exhausted(): Renamed from recv_sys_heap_check()
recv_sys_t::pages and its elements are allocated directly by the
system memory allocator.
recv_parse_log_recs(): Remove the parameter available_memory.
We rename some variables 'store_to_hash' to 'store', because
recv_sys.pages is not actually a hash table.
This is joint work with Thirunarayanan Balathandayuthapani.
Move tokuftdump and tokuft_logprint man pages to storage/tokudb.
The man pages are now part of tokudb-engine cmake component. This change
is mostly for RPM & DEB based packaging generated through CMake & CPack.
Debian upstream already handles this change via the custom scripts in debian/
Problem:
=======
The problem is that InnoDB doesn't add the table in fts slots if drop table fails. InnoDB marks the table is in fts slots while processing sync message. So the consecutive alter statement assumes that table is in queue and tries to remove it. But InnoDB can't find the table in fts_slots.
Solution:
=========
i) Removal of in_queue in fts_t while processing the fts sync message.
ii) Add the table to fts_slots when drop table fails.
[Variant 2 of the fix: collect the attached conditions]
Problem:
make_join_select() has a section of code which starts with
"We plan to scan all rows. Check again if we should use an index."
the code in that section will [unnecessarily] re-run the range
optimizer using this condition:
condition_attached_to_current_table AND current_table's_ON_expr
Note that the original invocation of range optimizer in
make_join_statistics was done using the whole select's WHERE condition.
Taking the whole select's WHERE condition and using multiple-equalities
allowed the range optimizer to infer more range restrictions.
The fix:
- Do range optimization using a condition that is an AND of this table's
condition and all of the previous tables' conditions.
- Also, fix the range optimizer to prefer SEL_ARGs with type=KEY_RANGE
over SEL_ARGS with type=MAYBE_KEY, regardless of the key part.
Computing
key_and(
SEL_ARG(type=MAYBE_KEY key_part=1),
SEL_ARG(type=KEY_RANGE, key_part=2)
)
will now produce the SEL_ARG with type=KEY_RANGE.
class log_file_t: more or less sane RAII wrapper around redo log file
descriptor and its path.
This change is motivated by the need of using that log_file_t somewhere else.
..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

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'.

Fix:
===
P1 - Fix)
Initialize cached_new_format,field_term_len, enclosed_len, line_term_len,
line_start_len, escaped_len members in default constructor.
P2 - Fix)
"var_header_len" is initialized by reading the event buffer. In case of an
invalid event the buffer will contain invalid data. Hence added a check to
validate the event data. If event_len is smaller than valid header length
return immediately.
P3 - Fix)
'm_table_id' within Table_map_log_event is initialized by reading data from
the event buffer. Use 'VALIDATE_BYTES_READ' macro to validate the current
state of the buffer. If it is invalid return immediately.
os_file_flush_data_func(): fix builds on POSIX OSs where fdatasync()
is not avaiable
log_t::files::flush_data_only(): rename from fdatasync()
log_t::files::fsync(): removed and replaced with flush_data_only().
It will flush everything we need for using redo log files.
This is the only symlink in the repository. Symlinks can cause
trouble when using file systems or operating systems that do not
support them.
Also remove the unused file DartConfig.cmake that refers to the script.
