The XtraDB option innodb_track_changed_pages causes
the function log_group_read_log_seg() to be invoked
even when recv_sys==NULL, leading to the SIGSEGV.
This regression was caused by
MDEV-11027 InnoDB log recovery is too noisy
Provide more useful progress reporting of crash recovery.
recv_sys_t::progress_time: The time of the last report.
recv_scan_print_counter: Remove.
log_group_read_log_seg(): After after each I/O request,
report progress if needed.
recv_apply_hashed_log_recs(): At the start of each batch,
if there are pages to be recovered, issue a message.

This makes it possible to do safe multi volume snapshots as long as one snapshots the volume with the transaction logs last.
include/mysql_com.h:
Added REFRESH_CHECKPOINT
mysql-test/r/flush.result:
Added test of new FLUSH TABLES syntax + calls to checkpoint_status handler calls
mysql-test/t/flush.test:
Added test of new FLUSH TABLES syntax + calls to checkpoint_status handler calls
sql/handler.cc:
Added code to call checkpoint_state for all handlertons that supports it
sql/handler.h:
Added new checkpoint_state() handlerton call to temporarly disable checkpoints.
sql/lex.h:
Added CHECKPOINT keyword
sql/sql_yacc.yy:
Added support for FLUSH TABLES WITH READ LOCK AND DISABLE CHECKPOINT
storage/maria/ha_maria.cc:
Added handlerton call to disable checkpoints.
storage/maria/ma_checkpoint.c:
Don't do checkpoint if checkpoints are disabled.
storage/maria/ma_static.c:
Added maria_checkpoint_disabled
storage/maria/maria_def.h:
Added maria_checkpoint_disabled
storage/xtradb/handler/ha_innodb.cc:
Added handlerton call to disable checkpoints.
storage/xtradb/include/log0log.h:
Added option to log_checkpoint() to allow one to ignore not critical checkpoints during the time checkpoints are disabled.
storage/xtradb/log/log0log.c:
Added code to allow one to disable checkpoints during a FLUSH TABLES ... DISABLE CHECKPOINT
This was done by adding a new argument to log_checkpoint() which tells us when the checkpoint is called by srv_master_thread (which are safe to ignore)
storage/xtradb/srv/srv0srv.c:
Tell log_checkpoint() that checkpoints from srv_master_thread() are safe to ignore (will just delay recovery time a bit).
This patch removes most remaining delays due to uninteruptible sleep()
during shutdown, as found using PMP. This makes standard test run very
close in speed to with --loose-innodb-fast-shutdown=2, and greatly
speeds up running the test suite.
sql/mysqld.cc:
Poll for threads to die every 20 msec during shutdown, rather than force
a wait for 2 full seconds should one thread be a little slow to exit
(this was seen occasionally in mysql-test-run).
storage/xtradb/include/srv0srv.h:
Rename the event, as we now use it to wakeup more threads during shutdown.
storage/xtradb/log/log0log.c:
Rename the event, as we now use it to wakeup more threads during shutdown.
storage/xtradb/srv/srv0srv.c:
Replace some hardcoded sleep()s with os_wait_event_time() that can be
interrupted early during server shutdown to avoid unnecessary delays.
Implement os_event_wait_time() for POSIX systems.
In the purge thread, use os_event_wait_time() when sleeping rather than sleep,
and signal the event when server shuts down, so we do not need to wait for
upto 10 seconds until the purge thread wakes up.
Also fix bug that warnings that were pushed after we call set_ok_status() were
not included in the waning count sent to the client in the result packet.
Also in mysqltest, in recursive die() invocation at least print the message
before aborting.
client/mysqltest.cc:
If we detect recursive die(), at least print the message before aborting.
mysql-test/r/warnings_debug.result:
Test case.
mysql-test/t/warnings_debug.test:
Test case.
sql/handler.cc:
Force generation of a warning with specific debug option, for testing.
sql/protocol.cc:
Fix wrong DBUG_ENTER
sql/sql_class.h:
Add method to count warnings pushed after set_ok_status() is called.
sql/sql_error.cc:
Also count warnings pushed after set_ok_status() is called.
storage/xtradb/include/os0sync.h:
Implement working os_sync_wait_time() for POSIX.
storage/xtradb/include/srv0srv.h:
Make the purge thread wait for an event when sleeping, so we can signal it to
wakeup immediately at shutdown.
storage/xtradb/log/log0log.c:
Make the purge thread wait for an event when sleeping, so we can signal it to
wakeup immediately at shutdown.
storage/xtradb/os/os0sync.c:
Implement working os_sync_wait_time() for POSIX.
storage/xtradb/srv/srv0srv.c:
Make the purge thread wait for an event when sleeping, so we can signal it to
wakeup immediately at shutdown.
Fixed compiler warnings
mysys/my_gethostbyname.c:
Added missing space from last push
storage/xtradb/handler/i_s.cc:
Removed not used variable
storage/xtradb/log/log0recv.c:
Removed not used variable
