main.derived_cond_pushdown: Move all 10.3 tests to the end,
trim trailing white space, and add an "End of 10.3 tests" marker.
Add --sorted_result to tests where the ordering is not deterministic.
main.win_percentile: Add --sorted_result to tests where the
ordering is no longer deterministic.
Remove threads that are doing nothing but wait
- main thread now handles the connections
(if threadpool is used, also threadpool threads would wait for connections)
- thread for socket and pipe connections are removed
- shutdown thread is now removed, we wait for shutdown
notification in main thread as well
- kill_server() is also called inside the main thread, after connection
loop finished.
Followup for 96b8909062. Only link mysqld with
${INTERFACE_LIBS} using LINK_PUBLIC, everything else should be
using LINK_PRIVATE. This restores pre-96b8909062c behavior.
Also fixes
MDEV-17010 Multiple definition issue on FreeBSD after 10.3.9 update
Added --skip-test-db option to mysql_install_db. If specified, no test
database created and relevant grants issued.
Removed --skip-auth-anonymous-user option of mysql_install_db. Now it is
covered by --skip-test-db.
Dropped some Debian patches that did the same.
Removed unused make_win_bin_dist.1, make_win_bin_dist and
mysql_install_db.pl.in.
This was done in, among other things:
- thd->db and thd->db_length
- TABLE_LIST tablename, db, alias and schema_name
- Audit plugin database name
- lex->db
- All db and table names in Alter_table_ctx
- st_select_lex db
Other things:
- Changed a lot of functions to take const LEX_CSTRING* as argument
for db, table_name and alias. See init_one_table() as an example.
- Changed some function arguments from LEX_CSTRING to const LEX_CSTRING
- Changed some lists from LEX_STRING to LEX_CSTRING
- threads_mysql.result changed because process list_db wasn't always
correctly updated
- New append_identifier() function that takes LEX_CSTRING* as arguments
- Added new element tmp_buff to Alter_table_ctx to separate temp name
handling from temporary space
- Ensure we store the length after my_casedn_str() of table/db names
- Removed not used version of rename_table_in_stat_tables()
- Changed Natural_join_column::table_name and db_name() to never return
NULL (used for print)
- thd->get_db() now returns db as a printable string (thd->db.str or "")
and specifically the ack receiving functionality.
Semisync is turned to be static instead of plugin so its functions
are invoked at the same points as RUN_HOOKS.
The RUN_HOOKS and the observer interface remain to be removed by later
patch.
Todo:
React on killed status by repl_semisync_master.wait_after_sync(). Currently
Repl_semi_sync_master::commit_trx does not check the killed status.
There were few bugfixes found that are present in mysql and its unclear
whether/how they are covered. Those include:
Bug#15985893: GTID SKIPPED EVENTS ON MASTER CAUSE SEMI SYNC TIME-OUTS
Bug#17932935 CALLING IS_SEMI_SYNC_SLAVE() IN EACH FUNCTION CALL
HAS BAD PERFORMANCE
Bug#20574628: SEMI-SYNC REPLICATION PERFORMANCE DEGRADES WITH A HIGH NUMBER OF THREADS
Part of MDEV-13073 AliSQL Optimize performance of semisync
Did the following renames to match other similar variables
key_ss_mutex_LOCK_binlog_ > key_LOCK_bing
key_ss_cond_COND_binlog_send_ -> key_COND_binlog_send
COND_binlog_send_ -> COND_binlog_send
LOCK_binlog_ -> LOCK_binlog
debian/mariadb-server-10.2.install does not install semisync libs.

DESCRIPTION
===========
If the .pid file is created at a world-writable location,
it can be compromised by replacing the server's pid with
another running server's (or some other non-mysql process)
PID causing abnormal behaviour.
ANALYSIS
========
In such a case, user should be warned that .pid file is
being created at a world-writable location.
FIX
===
A new function is_file_or_dir_world_writable() is defined
and it is called in create_pid_file() before .pid file
creation. If the location is world-writable, a relevant
warning is thrown.
NOTE
====
1. PID file is always created with permission bit 0664, so
for outside world its read-only.
2. Ignoring the case when permission is denied to get the
dir stats since the .pid file creation would fail anyway in
such a case.
As a result of this merge the code for the following tasks appears in 10.3:
- MDEV-12172 Implement tables specified by table value constructors
- MDEV-12176 Transform [NOT] IN predicate with long list of values INTO
[NOT] IN subquery.
Building with ninja shows the problem:

ninja: error: dependency cycle: sql/GenServerSource -> sql/CMakeFiles/GenServerSource -> sql/sql_builtin.cc -> cmake_order_depends_target_sq
sql/GenServerSource
Bug#16877045 5.6-CLUSTER-7.3 WIN32 SQL_YACC.CC BUILD PROBLEM
- Somewhat circular dependency caused by the configured files sql_builtin.cc being included as
part of the files to generate in sql/
- Move sql_builtin.cc out of GEN_SOURCES variable.
- Create new variable CONF_SOURCES to be used for configured files.
- the probably ultimate fix for dependencies on VS
- remove some GET_TARGET_PROPERTY(LOCATION ...), they are deprecated in
cmake 3.9
- simplify signing targets on Windows.
- remove INSTALL_DEBUG_TARGET, we do not mix binaries from different builds
in the same package
