-  Store a new message in an error object
-
-  This is used to in group_concat() to register how many warnings we actually
-  got after the query has been executed.
+  Design notes about MYSQL_ERROR::m_message_text.
+
+  The member MYSQL_ERROR::m_message_text contains the text associated with
+  an error, warning or note (which are all SQL 'conditions')
+
+  Producer of MYSQL_ERROR::m_message_text:
+  ----------------------------------------
+
+  (#1) the server implementation itself, when invoking functions like
+  my_error() or push_warning()
+
+  (#2) user code in stored programs, when using the SIGNAL statement.
+
+  (#3) user code in stored programs, when using the RESIGNAL statement.
+
+  When invoking my_error(), the error number and message is typically
+  provided like this:
+  - my_error(ER_WRONG_DB_NAME, MYF(0), ...);
+  - my_message(ER_SLAVE_IGNORED_TABLE, ER(ER_SLAVE_IGNORED_TABLE), MYF(0));
+
+  In both cases, the message is retrieved from ER(ER_XXX), which in turn
+  is read from the resource file errmsg.sys at server startup.
+  The strings stored in the errmsg.sys file are expressed in the character set
+  that corresponds to the server --language start option
+  (see error_message_charset_info).
+
+  When executing:
+  - a SIGNAL statement,
+  - a RESIGNAL statement,
+  the message text is provided by the user logic, and is expressed in UTF8.
+
+  Storage of MYSQL_ERROR::m_message_text:
+  ---------------------------------------
+
+  (#4) The class MYSQL_ERROR is used to hold the message text member.
+  This class represents a single SQL condition.
+
+  (#5) The class Warning_info represents a SQL condition area, and contains
+  a collection of SQL conditions in the Warning_info::m_warn_list
+
+  Consumer of MYSQL_ERROR::m_message_text:
+  ----------------------------------------
+
+  (#6) The statements SHOW WARNINGS and SHOW ERRORS display the content of
+  the warning list.
+
+  (#7) The GET DIAGNOSTICS statement (planned, not implemented yet) will
+  also read the content of:
+  - the top level statement condition area (when executed in a query),
+  - a sub statement (when executed in a stored program)
+  and return the data stored in a MYSQL_ERROR.
+
+  (#8) The RESIGNAL statement reads the MYSQL_ERROR caught by an exception
+  handler, to raise a new or modified condition (in #3).
+
+  The big picture

+
+  (#1) (my_error) produces data in the 'error_message_charset_info' CHARSET
+
+  (#2) and (#3) (SIGNAL, RESIGNAL) produces data internally in UTF8
+
+  (#6) (SHOW WARNINGS) produces data in the 'error_message_charset_info' CHARSET
+
+  (#7) (GET DIAGNOSTICS) is not implemented.
+
+  (#8) (RESIGNAL) produces data internally in UTF8 (see #3)
+
+  As a result, the design choice for (#4) and (#5) is to store data in
+  the 'error_message_charset_info' CHARSET, to minimize impact on the code base.
+  This is implemented by using 'String MYSQL_ERROR::m_message_text'.
+
+  The UTF8 -> error_message_charset_info conversion is implemented in
+  Signal_common::eval_signal_informations() (for path #B and #C).
+
+  Future work
+  -----------
+
+  - Change (#1) (my_error) to generate errors in UTF8.
+    See WL#751 (Recoding of error messages)
+
+  - Change (#4 and #5) to store message text in UTF8 natively.
+    In practice, this means changing the type of the message text to
+    '<UTF8 String 128 class> MYSQL_ERROR::m_message_text', and is a direct
+    consequence of WL#751.
+
+  - Implement (#9) (GET DIAGNOSTICS).
+    See WL#2111 (Stored Procedures: Implement GET DIAGNOSTICS)
