+  Signal that the first part of handler commit is finished, and that the
+  committed transaction is now visible and has fixed commit ordering with
+  respect to other transactions. The commit need _not_ be durable yet, and
+  typically will not be when this call makes sense.
+
+  This call is optional, if the storage engine does not call it the upper
+  layer will after the handler commit() method is done. However, the storage
+  engine may choose to call it itself to increase the possibility for group
+  commit.
+
+  In-order parallel replication uses this to apply different transaction in
+  parallel, but delay the commits of later transactions until earlier
+  transactions have committed first, thus achieving increased performance on
+  multi-core systems while still preserving full transaction consistency.
+
+  The storage engine can call this from within the commit() method, typically
+  after the commit record has been written to the transaction log, but before
+  the log has been fsync()'ed. This will allow the next replicated transaction
+  to proceed to commit before the first one has done fsync() or similar. Thus,
+  it becomes possible for multiple sequential replicated transactions to share
+  a single fsync() inside the engine in group commit.
+
+  Note that this method should _not_ be called from within the commit_ordered()
+  method, or any other place in the storage engine. When commit_ordered() is
+  used (typically when binlog is enabled), the transaction coordinator takes
+  care of this and makes group commit in the storage engine possible without
+  any other action needed on the part of the storage engine. This function
+  thd_wakeup_subsequent_commits() is only needed when no transaction
+  coordinator is used, meaning a single storage engine and no binary log.

+  to use the mysys file API with the performance schema instrumentation.
+  In some compilers (SunStudio), 'static inline' functions, when declared
+  but not used, are not optimized away (because they are unused) by default,
+  so that including a static inline function from a header file does
+  create unwanted dependencies, causing unresolved symbols at link time.
+  Other compilers, like gcc, optimize these dependencies by default.
+
+  Since the instrumented APIs declared here are wrapper on top
+  of mysys file io APIs, including mysql/psi/mysql_file.h assumes that
+  the dependency on my_sys already exists.

+  @file
+  == Debug Sync Facility ==
+
+  The Debug Sync Facility allows placement of synchronization points in
+  the server code by using the DEBUG_SYNC macro:
+
+      open_tables(...)
+
+      DEBUG_SYNC(thd, "after_open_tables");
+
+      lock_tables(...)
+
+  When activated, a sync point can
+
+    - Emit a signal and/or
+    - Wait for a signal
+
+  Nomenclature:
+
+    - signal:             A value of a global variable that persists
+                          until overwritten by a new signal. The global
+                          variable can also be seen as a "signal post"
+                          or "flag mast". Then the signal is what is
+                          attached to the "signal post" or "flag mast".
+
+    - emit a signal:      Assign the value (the signal) to the global
+                          variable ("set a flag") and broadcast a
+                          global condition to wake those waiting for
+                          a signal.
+
+    - wait for a signal:  Loop over waiting for the global condition until
+                          the global value matches the wait-for signal.
+
+  By default, all sync points are inactive. They do nothing (except to
+  burn a couple of CPU cycles for checking if they are active).
+
+  A sync point becomes active when an action is requested for it.
+  To do so, put a line like this in the test case file:
+
+      SET DEBUG_SYNC= 'after_open_tables SIGNAL opened WAIT_FOR flushed';
+
+  This activates the sync point 'after_open_tables'. It requests it to
+  emit the signal 'opened' and wait for another thread to emit the signal
+  'flushed' when the thread's execution runs through the sync point.
+
+  For every sync point there can be one action per thread only. Every
+  thread can request multiple actions, but only one per sync point. In
+  other words, a thread can activate multiple sync points.
+
+  Here is an example how to activate and use the sync points:
+
+      --connection conn1
+      SET DEBUG_SYNC= 'after_open_tables SIGNAL opened WAIT_FOR flushed';
+      send INSERT INTO t1 VALUES(1);
+          --connection conn2
+          SET DEBUG_SYNC= 'now WAIT_FOR opened';
+          SET DEBUG_SYNC= 'after_abort_locks SIGNAL flushed';
+          FLUSH TABLE t1;
+
+  When conn1 runs through the INSERT statement, it hits the sync point
+  'after_open_tables'. It notices that it is active and executes its
+  action. It emits the signal 'opened' and waits for another thread to
+  emit the signal 'flushed'.
+
+  conn2 waits immediately at the special sync point 'now' for another
+  thread to emit the 'opened' signal.
+
+  A signal remains in effect until it is overwritten. If conn1 signals
+  'opened' before conn2 reaches 'now', conn2 will still find the 'opened'
+  signal. It does not wait in this case.
+
+  When conn2 reaches 'after_abort_locks', it signals 'flushed', which lets
+  conn1 awake.
+
+  Normally the activation of a sync point is cleared when it has been
+  executed. Sometimes it is necessary to keep the sync point active for
+  another execution. You can add an execute count to the action:
+
+      SET DEBUG_SYNC= 'name SIGNAL sig EXECUTE 3';
+
+  This sets the signal point's activation counter to 3. Each execution
+  decrements the counter. After the third execution the sync point
+  becomes inactive.
+
+  One of the primary goals of this facility is to eliminate sleeps from
+  the test suite. In most cases it should be possible to rewrite test
+  cases so that they do not need to sleep. (But this facility cannot
+  synchronize multiple processes.) However, to support test development,
+  and as a last resort, sync point waiting times out. There is a default
+  timeout, but it can be overridden:
+
+      SET DEBUG_SYNC= 'name WAIT_FOR sig TIMEOUT 10 EXECUTE 2';
+
+  TIMEOUT 0 is special: If the signal is not present, the wait times out
+  immediately.
+
+  When a wait timed out (even on TIMEOUT 0), a warning is generated so
+  that it shows up in the test result.
+
+  You can throw an error message and kill the query when a synchronization
+  point is hit a certain number of times:
+
+      SET DEBUG_SYNC= 'name HIT_LIMIT 3';
+
+  Or combine it with signal and/or wait:
+
+      SET DEBUG_SYNC= 'name SIGNAL sig EXECUTE 2 HIT_LIMIT 3';
+
+  Here the first two hits emit the signal, the third hit returns the error
+  message and kills the query.
+
+  For cases where you are not sure that an action is taken and thus
+  cleared in any case, you can force to clear (deactivate) a sync point:
+
+      SET DEBUG_SYNC= 'name CLEAR';
+
+  If you want to clear all actions and clear the global signal, use:
+
+      SET DEBUG_SYNC= 'RESET';
+
+  This is the only way to reset the global signal to an empty string.
+
+  For testing of the facility itself you can execute a sync point just
+  as if it had been hit:
+
+      SET DEBUG_SYNC= 'name TEST';
+
+
+  === Formal Syntax ===
+
+  The string to "assign" to the DEBUG_SYNC variable can contain:
+
+      {RESET |
+       <sync point name> TEST |
+       <sync point name> CLEAR |
+       <sync point name> {{SIGNAL <signal name> |
+                           WAIT_FOR <signal name> [TIMEOUT <seconds>]}
+                          [EXECUTE <count>] &| HIT_LIMIT <count>}
+
+  Here '&|' means 'and/or'. This means that one of the sections
+  separated by '&|' must be present or both of them.
+
+
+  === Activation/Deactivation ===
+
+  The facility is an optional part of the MySQL server.
+  It is enabled in a debug server by default.
+
+      ./configure --enable-debug-sync
+
+  The Debug Sync Facility, when compiled in, is disabled by default. It
+  can be enabled by a mysqld command line option:
+
+      --debug-sync-timeout[=default_wait_timeout_value_in_seconds]
+
+  'default_wait_timeout_value_in_seconds' is the default timeout for the
+  WAIT_FOR action. If set to zero, the facility stays disabled.
+
+  The facility is enabled by default in the test suite, but can be
+  disabled with:
+
+      mysql-test-run.pl ... --debug-sync-timeout=0 ...
+
+  Likewise the default wait timeout can be set:
+
+      mysql-test-run.pl ... --debug-sync-timeout=10 ...
+
+  The command line option influences the readable value of the system
+  variable 'debug_sync'.
+
+  * If the facility is not compiled in, the system variable does not exist.
+
+  * If --debug-sync-timeout=0 the value of the variable reads as "OFF".
+
+  * Otherwise the value reads as "ON - current signal: " followed by the
+    current signal string, which can be empty.
+
+  The readable variable value is the same, regardless if read as global
+  or session value.
+
+  Setting the 'debug-sync' system variable requires 'SUPER' privilege.
+  You can never read back the string that you assigned to the variable,
+  unless you assign the value that the variable does already have. But
+  that would give a parse error. A syntactically correct string is
+  parsed into a debug sync action and stored apart from the variable value.
+
+
+  === Implementation ===
+
+  Pseudo code for a sync point:
+
+      #define DEBUG_SYNC(thd, sync_point_name)
+                if (unlikely(opt_debug_sync_timeout))
+                  debug_sync(thd, STRING_WITH_LEN(sync_point_name))
+
+  The sync point performs a binary search in a sorted array of actions
+  for this thread.
+
+  The SET DEBUG_SYNC statement adds a requested action to the array or
+  overwrites an existing action for the same sync point. When it adds a
+  new action, the array is sorted again.
+
+
+  === A typical synchronization pattern ===
+
+  There are quite a few places in MySQL, where we use a synchronization
+  pattern like this:
+
+  mysql_mutex_lock(&mutex);
+  thd->enter_cond(&condition_variable, &mutex, new_message);
+  #if defined(ENABLE_DEBUG_SYNC)
+  if (!thd->killed && !end_of_wait_condition)
+     DEBUG_SYNC(thd, "sync_point_name");
+  #endif
+  while (!thd->killed && !end_of_wait_condition)
+    mysql_cond_wait(&condition_variable, &mutex);
+  thd->exit_cond(old_message);
+
+  Here some explanations:
+
+  thd->enter_cond() is used to register the condition variable and the
+  mutex in thd->mysys_var. This is done to allow the thread to be
+  interrupted (killed) from its sleep. Another thread can find the
+  condition variable to signal and mutex to use for synchronization in
+  this thread's THD::mysys_var.
+
+  thd->enter_cond() requires the mutex to be acquired in advance.
+
+  thd->exit_cond() unregisters the condition variable and mutex and
+  releases the mutex.
+
+  If you want to have a Debug Sync point with the wait, please place it
+  behind enter_cond(). Only then you can safely decide, if the wait will
+  be taken. Also you will have THD::proc_info correct when the sync
+  point emits a signal. DEBUG_SYNC sets its own proc_info, but restores
+  the previous one before releasing its internal mutex. As soon as
+  another thread sees the signal, it does also see the proc_info from
+  before entering the sync point. In this case it will be "new_message",
+  which is associated with the wait that is to be synchronized.
+
+  In the example above, the wait condition is repeated before the sync
+  point. This is done to skip the sync point, if no wait takes place.
+  The sync point is before the loop (not inside the loop) to have it hit
+  once only. It is possible that the condition variable is signaled
+  multiple times without the wait condition to be true.
+
+  A bit off-topic: At some places, the loop is taken around the whole
+  synchronization pattern:
+
+  while (!thd->killed && !end_of_wait_condition)
+  {
+    mysql_mutex_lock(&mutex);
+    thd->enter_cond(&condition_variable, &mutex, new_message);
+    if (!thd->killed [&& !end_of_wait_condition])
+    {
+      [DEBUG_SYNC(thd, "sync_point_name");]
+      mysql_cond_wait(&condition_variable, &mutex);
+    }
+    thd->exit_cond(old_message);
+  }
+
+  Note that it is important to repeat the test for thd->killed after
+  enter_cond(). Otherwise the killing thread may kill this thread after
+  it tested thd->killed in the loop condition and before it registered
+  the condition variable and mutex in enter_cond(). In this case, the
+  killing thread does not know that this thread is going to wait on a
+  condition variable. It would just set THD::killed. But if we would not
+  test it again, we would go asleep though we are killed. If the killing
+  thread would kill us when we are after the second test, but still
+  before sleeping, we hold the mutex, which is registered in mysys_var.
+  The killing thread would try to acquire the mutex before signaling
+  the condition variable. Since the mutex is only released implicitly in
+  mysql_cond_wait(), the signaling happens at the right place. We
+  have a safe synchronization.
+
+  === Co-work with the DBUG facility ===
+
+  When running the MySQL test suite with the --debug-dbug command line
+  option, the Debug Sync Facility writes trace messages to the DBUG
+  trace. The following shell commands proved very useful in extracting
+  relevant information:
+
+  egrep 'query:|debug_sync_exec:' mysql-test/var/log/mysqld.1.trace
+
+  It shows all executed SQL statements and all actions executed by
+  synchronization points.
+
+  Sometimes it is also useful to see, which synchronization points have
+  been run through (hit) with or without executing actions. Then add
+  "|debug_sync_point:" to the egrep pattern.

+/**
+  @file
+  encryption scheme service
+
+  A higher-level access to encryption service.
+
+  This is a helper service that storage engines use to encrypt tables on disk.
+  It requests keys from the plugin, generates temporary or local keys
+  from the global (as returned by the plugin) keys, etc.
+
+  To use the service:
+
+  * st_encryption_scheme object is created per space. A "space" can be
+    a table space in XtraDB/InnoDB, a file in Aria, etc.  The whole
+    space is encrypted with the one key id.
+
+  * The service does not take the key and the IV as parameters for
+    encryption or decryption. Instead it takes two 32-bit integers and
+    one 64-bit integer (and requests the key from an encryption
+    plugin, if needed).
+
+  * The service requests the global key from the encryption plugin
+    automatically as needed. Three last keys are cached in the
+    st_encryption_scheme. Number of key requests (number of cache
+    misses) are counted in st_encryption_scheme::keyserver_requests
+
+  * If an st_encryption_scheme can be used concurrently by different
+    threads, it needs to be able to lock itself when accessing the key
+    cache.  Set the st_encryption_scheme::locker appropriately. If
+    non-zero, it will be invoked by encrypt/decrypt functions to lock
+    and unlock the scheme when needed.
+
+  * Implementation details (in particular, key derivation) are defined
+    by the scheme type. Currently only schema type 1 is supported.
+
+  In the schema type 1, every "space" (table space in XtraDB/InnoDB,
+  file in Aria) is encrypted with a different space-local key:
+
+  * Every space has a 16-byte unique identifier (typically it's
+    generated randomly and stored in the space). The caller should
+    put it into st_encryption_scheme::iv.
+
+  * Space-local key is generated by encrypting this identifier with
+    the global encryption key (of the given id and version) using AES_ECB.
+
+  * Encryption/decryption parameters for a page are typically the
+    4-byte space id, 4-byte page position (offset, page number, etc),
+    and the 8-byte LSN. This guarantees that they'll be different for
+    any two pages (of the same or different tablespaces) and also that
+    they'll change for the same page when it's modified. They don't need
+    to be secret (they create the IV, not the encryption key).

+
+  Log file with rotation implementation.
+
+  This service implements logging with possible rotation
+  of the log files. Interface intentionally tries to be similar to FILE*
+  related functions.
+
+  So that one can open the log with logger_open(), specifying
+  the limit on the logfile size and the rotations number.
+
+  Then it's possible to write messages to the log with
+  logger_printf or logger_vprintf functions.
+
+  As the size of the logfile grows over the specified limit,
+  it is renamed to 'logfile.1'. The former 'logfile.1' becomes
+  'logfile.2', etc. The file 'logfile.rotations' is removed.
+  That's how the rotation works.
+
+  The rotation can be forced with the logger_rotate() call.
+
+  Finally the log should be closed with logger_close().
+
+@notes:
+  Implementation checks the size of the log file before it starts new
+  printf into it. So the size of the file gets over the limit when it rotates.
+
+  The access is secured with the mutex, so the log is threadsafe.

+/**
+  @file
+  my_snprintf service
+
+  Portable and limited vsnprintf() implementation.
+
+  This is a portable, limited vsnprintf() implementation, with some
+  extra features. "Portable" means that it'll produce identical result
+  on all platforms (for example, on Windows and Linux system printf %e
+  formats the exponent differently, on different systems %p either
+  prints leading 0x or not, %s may accept null pointer or crash on
+  it). "Limited" means that it does not support all the C89 features.
+  But it supports few extensions, not in any standard.
+
+  my_vsnprintf(to, n, fmt, ap)
+
+  @param[out] to     A buffer to store the result in
+  @param[in]  n      Store up to n-1 characters, followed by an end 0
+  @param[in]  fmt    printf-like format string
+  @param[in]  ap     Arguments
+
+  @return a number of bytes written to a buffer *excluding* terminating '\0'
+
+  @post
+  The syntax of a format string is generally the same:
+  % <flag> <width> <precision> <length modifier> <format>
+  where everithing but the format is optional.
+
+  Three one-character flags are recognized:
+    '0' has the standard zero-padding semantics;
+    '-' is parsed, but silently ignored;
+    '`' (backtick) is only supported for strings (%s) and means that the
+        string will be quoted according to MySQL identifier quoting rules.
+
+  Both <width> and <precision> can be specified as numbers or '*'.
+  If an asterisk is used, an argument of type int is consumed.
+
+  <length modifier> can be 'l', 'll', or 'z'.
+
+  Supported formats are 's' (null pointer is accepted, printed as
+  "(null)"), 'b' (extension, see below), 'c', 'd', 'i', 'u', 'x', 'o',
+  'X', 'p' (works as 0x%x), 'f', 'g', 'M' (extension, see below),
+  'T' (extension, see below).
+
+  Standard syntax for positional arguments $n is supported.
+
+  Extensions:
+
+  Flag '`' (backtick): see above.
+
+  Format 'b': binary buffer, prints exactly <precision> bytes from the
+  argument, without stopping at '\0'.
+
+  Format 'M': takes one integer, prints this integer, space, double quote
+  error message, double quote. In other words
+    printf("%M", n) === printf("%d \"%s\"", n, strerror(n))
+
+  Format 'T': takes string and print it like s but if the strints should be
+  truncated puts "..." at the end.

+  THD specific for plugin(s)
+
+  This API provides pthread_getspecific like functionality to plugin authors.
+  This is a functional alternative to the declarative MYSQL_THDVAR
+
+  A plugin should at init call thd_key_create that create a key that
+  will have storage in each THD. The key should be used by all threads
+  and can be used concurrently from all threads.
+
+  A plugin should at deinit call thd_key_delete.
+
+  Alternatively, a plugin can use thd_key_create_from_var(K,V) to create
+  a key that corresponds to a named MYSQL_THDVAR variable.
+
+  This API is also safe when using pool-of-threads in which case
+  pthread_getspecific is not, because the actual OS thread may change.
+
+  @note
+
+  Normally one should prefer MYSQL_THDVAR declarative API.
+
+  The benefits are:
+
+  - It supports typed variables (int, char*, enum, etc), not only void*.
+  - The memory allocated for MYSQL_THDVAR is free'd automatically
+    (if PLUGIN_VAR_MEMALLOC is specified).
+  - Continuous loading and unloading of the same plugin does not allocate
+    memory for same variables over and over again.
+
+  An example of using MYSQL_THDVAR for a thd local storage:
+
+    MYSQL_THDVAR_STR(my_tls,
+            PLUGIN_VAR_MEMALLOC | PLUGIN_VAR_NOSYSVAR | PLUGIN_VAR_NOCMDOPT,
+            "thd local storage example", 0, 0, 0);

+  @file include/mysql/service_thd_wait.h
+  This service provides functions for plugins and storage engines to report
+  when they are going to sleep/stall.
+  
+  SYNOPSIS
+  thd_wait_begin() - call just before a wait begins
+  thd                     Thread object
+                          Use NULL if the thd is NOT known.
+  wait_type               Type of wait
+                          1 -- short wait (e.g. for mutex)
+                          2 -- medium wait (e.g. for disk io)
+                          3 -- large wait (e.g. for locked row/table)
+  NOTES
+    This is used by the threadpool to have better knowledge of which
+    threads that currently are actively running on CPUs. When a thread
+    reports that it's going to sleep/stall, the threadpool scheduler is
+    free to start another thread in the pool most likely. The expected wait
+    time is simply an indication of how long the wait is expected to
+    become, the real wait time could be very different.
+
+  thd_wait_end() called immediately after the wait is complete
+
+  thd_wait_end() MUST be called if thd_wait_begin() was called.
+
+  Using thd_wait_...() service is optional but recommended.  Using it will
+  improve performance as the thread pool will be more active at managing the
+  thread workload.

+  One should only report wait events that could potentially block for a
+  long time. A mutex wait is too short of an event to report. The reason
+  is that an event which is reported leads to a new thread starts
+  executing a query and this has a negative impact of usage of CPU caches
+  and thus the expected gain of starting a new thread must be higher than
+  the expected cost of lost performance due to starting a new thread.
+
+  Good examples of events that should be reported are waiting for row locks
+  that could easily be for many milliseconds or even seconds and the same
+  holds true for global read locks, table locks and other meta data locks.
+  Another event of interest is going to sleep for an extended time.
