Implement a fix for Bug#57058 -- send SERVER_QUERY_WAS_SLOW over
network when a query was slow.
When a query is slow, sent a special flag to the client
indicating this fact.
Add a test case.
Implement review comments.
include/mysql_com.h:
Clear SERVER_QUERY_WAS_SLOW at end of each statement.
Since this patch removes the technique when
thd->server_status is modified briefly only to
execute my_eof(), reset more server status
bit that may remain in the status from
execution of the previous statement.
sql/protocol.cc:
Always use thd->server_status to
in net_* functions to send the latest
status to the client.
sql/sp_head.cc:
Calculate if a query was slow before
sending EOF packet.
sql/sql_cursor.cc:
Remove juggling with thd->server_status.
The extra status bits are reset at
start of the next statement.
sql/sql_db.cc:
Remove juggling with thd->server_status.
The extra status bits are reset at
start of the next statement.
sql/sql_error.cc:
Remove m_server_status member,
it's not really part of the Diagnostics_area.
sql/sql_error.h:
Remove server_status member, it's
not part of the Diagnostics_area.
The associated hack is removed as well.
sql/sql_parse.cc:
Do not calculate if a query was
slow twice. Use a status flag in thd->server_status.
tests/mysql_client_test.c:
Add a test case for Bug#57058.
Check that the status is present
at the client, when sent.
