Also, implement MDEV-11027 a little differently from 5.5 and 10.0:
recv_apply_hashed_log_recs(): Change the return type back to void
(DB_SUCCESS was always returned).
Report progress also via systemd using sd_notifyf().
Also, implement MDEV-11027 a little differently from 5.5:
recv_sys_t::report(ib_time_t): Determine whether progress should
be reported.
recv_apply_hashed_log_recs(): Rename the parameter to last_batch.
Implementation of MDEV-7660 introduced unwanted incompatible change:
modifications under LOCK TABLES with autocommit enabled are rolled back on
disconnect. Previously everything was committed, because LOCK TABLES didn't
adjust autocommit setting.
This patch restores original behavior by reverting some changes done in
MDEV-7660:
- sql/sql_parse.cc: do not reset autocommit on LOCK TABLES
- sql/sql_base.cc: do not set autocommit on UNLOCK TABLES
- test cases: main.lock_tables_lost_commit, main.partition_explicit_prune,
rpl.rpl_switch_stm_row_mixed, tokudb.nested_txn_implicit_commit,
tokudb_bugs.db806
But it makes InnoDB tables under LOCK TABLES ... READ [LOCAL] not protected
against DML. To restore protection some changes from WL#6671 were merged,
specifically MDL_SHARED_READ_ONLY and test cases.
WL#6671 merge highlights:
- Not all tests merged.
- In MySQL LOCK TABLES ... READ acquires MDL_SHARED_READ_ONLY for all engines,
in MariaDB MDL_SHARED_READ is always acquired first and then upgraded to
MDL_SHARED_READ_ONLY for InnoDB only.
- The above allows us to omit MDL_SHARED_WRITE_LOW_PRIO implementation in
MariaDB, which is rather useless with InnoDB. In MySQL it is needed to
preserve locking behavior between low priority writes and LOCK TABLES ... READ
for non-InnoDB engines (covered by sys_vars.sql_low_priority_updates_func).
- Omitted HA_NO_READ_LOCAL_LOCK, we rely on lock_count() instead.
- Omitted "piglets": in MariaDB stream of DML against InnoDB table may lead to
concurrent LOCK TABLES ... READ starvation.
- HANDLER ... OPEN acquires MDL_SHARED_READ instead of MDL_SHARED in MariaDB.
- Omitted SNRW->X MDL lock upgrade for IMPORT/DISCARD TABLESPAECE under LOCK
TABLES.
- Omitted strong locks for views, triggers and SP under LOCK TABLES.
- Omitted IX schema lock for LOCK TABLES READ.
- Omitted deadlock weight juggling for LOCK TABLES.

MySQL has a bug failing to handle
MYSQL_THDVAR_STR(... PLUGIN_VAR_NOSYSVAR |
PLUGIN_VAR_NOCMDOPT | PLUGIN_VAR_MEMALLOC)
so fall back to just PLUGIN_VAR_READONLY | PLUGIN_VAR_MEMALLOC
whem MySQL started.
Building AWS C++ SDK as external project needs CMake 2.8.12
Centos7 out of the box has 2.8.11, thus the build fails.
Fixed check for required CMake version.
Clean-up nolock.h: it doesn't serve any purpose anymore. Appropriate code moved
to x86-gcc.h and my_atomic.h.
If gcc sync bultins were detected, we want to make use of them independently of
__GNUC__ definition. E.g. XLC simulates those, but doesn't define __GNUC__.
HS/Spider: According to AIX manual alloca() returns char*, which cannot be
casted to any type with static_cast. Use explicit cast instead.
MDL: Removed namemangling pragma, which didn't let MariaDB build with XLC.
WSREP: _int64 seem to be conflicting name with XLC, replaced with _integer64.
CONNECT: RTLD_NOLOAD is GNU extention. Removed rather meaningless check if
library is loaded. Multiple dlopen()'s of the same library are permitted,
and it never gets closed anyway. Except for error, which was a bug: it may
close library, which can still be referenced by other subsystems.
InnoDB: __ppc_get_timebase() is GNU extention. Only use it when __GLIBC__ is
defined.
Based on contribution by flynn1973.
AWS C++ SDK always defaults region to us-east-1 for clientConfiguration
(ignoring config file or env.variable)
This patch introduces a plugin variable 'region' to make it usable
for master keys created in regions other than 'us-east-1'.
On OS X with clang 7.3.0 running any test as embedded crashes. As
libfeedback was not compiled with embedded, we had 2 notions of THD,
with different number of members. When calling inline functions defined in
sql_class.h, the functions were defined for 1 THD but called on an
object that is different. This resulted in erroneous data being returned
and shortly after, a crash within the alloc_query() function.
Recompile the feedback plugin for the embedded server specifically to
not have such symbol conflicts.
- Library path's are different now
- New dependency on Linux libuuid
- Add calls for SDK Initialization/shutdown
- Also add request_timeout parameter, default SDK HTTPs timeout appears
to be too short in my tests
