the func version run good but the basic versions fail.
- Sent innodb.test to dev@innodb.com.

Between 5.0 and 5.1, the step of incrementing the global query id

halfway through a query (as happens in "SET SESSION PROFILING = ...")
has a few side-effects, the worst of which is a memory leak for
prepared statements, which poke directly from the parser into the
profiling code (we don't have the query text when we need it) and
that overwrites a pointer to heap-allocated memory when the previous
statement turns on profiling.
Instead, now set a flag when we begin a new statement that tracks
whether profiling is on _at the start_ of the query. Use that to
track whether we gather info.
Additionally, use that AND use the state of the profiling variable
after the end of a query to know whether to store information about
the query that just finished.
mysql-test/r/profiling.result:
Testing whether profiling is on at the beginning of a query and at
the end of a query makes "SET SESSION PROFILING = ..." statements
disappear from the profiling. They were never reliable before.
sql/sql_profile.cc:
Check to see if profiling was enabled at the beginning of this query
before trying to store query_source. This avoids a memory leak for
prepared statements, which get here by direct means.

sql/sql_profile.h:
Keep track of whether profiling is on.
is a special case in "SHOW PROFILE FOR QUERY n". No one can get

because zero represents the final item, internally.
Now, order the queries starting at one.
mysql-test/r/profiling.result:
Renumber the query IDs.
sql/sql_profile.cc:
Start the profile_id_counter at 1, to overstep the special-case

B-g#27501: 5.0 significantly more sys ("kernel") time than 4.1 \

Even if profiling is turned off, the parser makes calls to reset
the state at the beginning of each query. That would eventually
instantiate a PROFILE_ENTRY, which does indeed capture resource
usage.
Instead, now check that profiling is active before progressing
far into the storage/expiration of old entries in the history.
This has the pleasant side-effect that queries to toggle profiling
are not recorded in the history.
mysql-test/r/profiling.result:
Now after we turn off profiling, the beginning of the next query
refuses to enter the profiling code and it discards the info.
sql/sql_profile.cc:
Add the same condition twice: Once to abort storing previous
query information and the other to abort initialization for this
query that is starting.
We do this symmetrically, before and after expiring old history
entries, so that the counts are correct.

Bug#24795: SHOW PROFILE
Profiling is only partially functional on some architectures. Where
there is no getrusage() system call, presently Null values are
returned where it would be required. Notably, Windows needs some love
applied to make it as useful.
Syntax this adds:
SHOW PROFILES
SHOW PROFILE [types] [FOR QUERY n] [OFFSET n] [LIMIT n]
where "n" is an integer
and "types" is zero or many (comma-separated) of
"CPU"
"MEMORY" (not presently supported)
"BLOCK IO"
"CONTEXT SWITCHES"
"PAGE FAULTS"
"IPC"
"SWAPS"
"SOURCE"
"ALL"
It also adds a session variable (boolean) "profiling", set to "no"
by default, and (integer) profiling_history_size, set to 15 by
default.
This patch abstracts setting THDs' "proc_info" behind a macro that
can be used as a hook into the profiling code when profiling
support is compiled in. All future code in this line should use
that mechanism for setting thd->proc_info.
---
Tests are now set to omit the statistics.
---
Adds an Information_schema table, "profiling" for access to
"show profile" data.
