/**
Skip trailing space.
On most systems reading memory in larger chunks (ideally equal to the size of
the chinks that the machine physically reads from memory) causes fewer memory
access loops and hence increased performance.
This is why the 'int' type is used : it's closest to that (according to how
it's defined in C).
So when we determine the amount of whitespace at the end of a string we do
the following :
1. We divide the string into 3 zones :
a) from the start of the string (__start) to the first multiple
of sizeof(int) (__start_words)
b) from the end of the string (__end) to the last multiple of sizeof(int)
(__end_words)
c) a zone that is aligned to sizeof(int) and can be safely accessed
through an int *
2. We start comparing backwards from (c) char-by-char. If all we find is
space then we continue
3. If there are elements in zone (b) we compare them as unsigned ints to a
int mask (SPACE_INT) consisting of all spaces
4. Finally we compare the remaining part (a) of the string char by char.
This covers for the last non-space unsigned int from 3. (if any)
This algorithm works well for relatively larger strings, but it will slow
the things down for smaller strings (because of the additional calculations
and checks compared to the naive method). Thus the barrier of length 20
is added.
@param ptr pointer to the input string
@param len the length of the string
@return the last non-space character

type: The token type. Should be one of the enum_ft_token_type values.

>0 Must be present
<0 Must not be present
0 Neither; the word is optional but its presence increases the relevance
With the default settings of the ft_boolean_syntax system variable,
>0 corresponds to the '+' operator, <0 corrresponds to the '-' operator,
and 0 means neither operator was used.
weight_adjust: A weighting factor that determines how much a match
for the word counts. Positive values increase, negative - decrease the
relative word's importance in the query.
wasign: The sign of the word's weight in the query. If it's non-negative
the match for the word will increase document relevance, if it's
negative - decrease (the word becomes a "noise word", the less of it the
better).
trunc: Corresponds to the '*' operator in the default setting of the
ft_boolean_syntax system variable.

server. It's set by the server and can be used by the parser plugin
to invoke the MySQL default parser. If plugin's role is to extract
textual data from .doc, .pdf or .xml content, it might extract
plaintext from the content, and then pass the text to the default
MySQL parser to be parsed.
mysql_add_word: A server callback to add a new word. When parsing
a document, the server sets this to point at a function that adds
the word to MySQL full-text index. When parsing a search query,
this function will add the new word to the list of words to search
for. The boolean_info argument can be NULL for all cases except
when mode is MYSQL_FTPARSER_FULL_BOOLEAN_INFO.
ftparser_state: A generic pointer. The plugin can set it to point
to information to be used internally for its own purposes.
mysql_ftparam: This is set by the server. It is used by MySQL functions
called via mysql_parse() and mysql_add_word() callback. The plugin
should not modify it.
cs: Information about the character set of the document or query string.
doc: A pointer to the document or query string to be parsed.

These lists are defined with PROTOCOL_STAGE_LIST() and TRACE_EVENT_LIST(),

For example, to process list of protocol stages using disposition "foo",
define protocol_stage_foo(Stage) macro and then put
PROTOCOL_STAGE_LIST(foo)

/**
Protocol stages
---------------
A client following the MySQL protocol goes through several stages of it. Each
stage determines what packets can be expected from the server or can be send
by the client.
Upon receiving each trace event, trace plugin will be notified of the current
protocol stage so that it can correctly interpret the event.
These are the possible protocol stages and the transitions between them.

Executes a server command in a session.
There are two cases. Execution in a physical thread :

2. NOT initialized by the srv_session service
In case of 1, if there is currently attached session, and it is
different from the passed one, the former will be automatically
detached. The session to be used for the execution will then be
attached. After the command is executed, the attached session will
not be detached. It will be detached by a next call to run_command()
with another session as parameter. In other words, for all sessions
used in a physical thread, there will be at most one in attached
state.
In case of 2, the current state (current_thd) will be
preserved. Then the given session will move to attached state and
the command will be executed. After the execution the state of the
session will be changed to detached and the preserved state
(current_thd) will be restored.
The client charset is used for commands like COM_QUERY and
COM_STMT_PREPARE to know how to threat the char* fields. This
charset will be used until the next call of run_command when it may
be changed again.

/**
@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).
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'.

/**
@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.
Note that user-level locks no longer use THD_WAIT_USER_LOCK wait type.
Since their implementation relies on metadata locks manager it uses
THD_WAIT_META_DATA_LOCK instead.
