| * many changes to my_getsystime.c:Sergei Golubchik2011-05-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * my_getsystime() is only an interval timer. Its value can beused for calculating time intervals. * renamed my_getsystime() to my_interval_timer(), to make the semantics clearer and let the compiler catch wrong usages of my_getsystime() (also future ones, that may come in merges). * increased its granularity from 100ns to 1ns, old value was for UUID, but as UUID can no longer use it directly there is no need to downgrade the OS provided value * fixed the UUID code to anchor the my_interval_timer() on the epoch, as required by the UUID standard. That is, this was only needed by UUID, and now I've moved it to UUID code from my_getsystime(). * fixed other wrong usages of my_getsystime() - e.g. in calculating times for pthread_cond_timedwait. It was buggy and could've caused long waits if OS clock would be changed.

SunStudio also warns about variables defined in local socpe or method arguments that have the same name as a member attribute of the class. This patch renames methods that might hide base class methods, to make it easier both for humans and compilers to see what is actually called. It also renames variables in local scope. sql/field.cc: Local scope variable or method argument same as class attribute. sql/item_cmpfunc.cc: Local scope variable or method argument same as class attribute. sql/item_create.cc: Renaming base class create() to create_func(). sql/item_create.h: Renaming base class create() to create_func(). sql/protocol.cc: Local scope variable or method argument same as class attribute. sql/sql_profile.cc: Local scope variable or method argument same as class attribute. sql/sql_select.cc: Local scope variable or method argument same as class attribute. sql/sql_yacc.yy: Renaming base class create() to create_func(). storage/federated/ha_federated.cc: Local scope variable or method argument same as class attribute. storage/myisammrg/ha_myisammrg.cc: Local scope variable or method argument same as class attribute.

Many were simply not ignoring what they were meant to. client/mysqlslap.c: Fixed bug for Bug#31173: mysqlslap.exe crashes if called without any parameters The original patch could cause memory leaks and odd problems depending on how connection was made. This code ensures that all mysql_options() are set for each mysql_real_connect(). (This patch by Monty) mysys/my_thr_init.c: Fixed multiply-initialized critical section on Windows, due to code incorrectly checking the wrong field in an attempt to prevent multiple-initialization. sql-common/client.c: Don't use shared memory if it's not set (for example after failed mysql_real_connect). Ensure that mysql_close() resets all resources so that it's safe to call it twice. (Patch by monty, related to Bug#31173: mysqlslap.exe crashes if called without any parameters) sql/CMakeLists.txt: Added page fault counters for SHOW PROFILE on Windows. sql/mysqld.cc: Fixed attempt to set a NULL event. The code now only sets the event if appropriate (i.e. shared memory is being used) sql/sql_profile.cc: Added page fault counters for SHOW PROFILE on Windows. sql/sql_profile.h: Added page fault counters for SHOW PROFILE on Windows. sql/udf_example.def: Some cleanup functions were not exported from udf_example.dll, causing them to never be executed, and as a result multiple-initialization of kernel objects occurred and resources were not being freed correctly. storage/maria/ma_close.c: Condition variable share->key_del_cond was never being destroyed, while its containing heap block was being freed in maria_close(), leaking kernel resources.

* Rewrite profiler code to be easier to maintain and less buggy.unknown2007-11-091-202/+209
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Between 5.0 and 5.1, the step of incrementing the global query id changed, which broke how the profiler noticed when a new query had started. That reset the state list and caused all but the last five (or so) states to be thrown away. Now, don't watch for query_id changes in the lower level. Add a bogus state change at the end of profiling so that the last real state change is timed. Emit source reference for the start of the span of time instead of the end of it. mysql-test/r/profiling.result: Add a test that shows continuation of execution with multi-statement packets. mysql-test/t/profiling.test: Add a test that shows continuation of execution with multi-statement packets. sql/sql_parse.cc: Insert profiling calls at beginnings and ends of each query. Remove the old way of keeping or discarding profiles, and flipping to new query profiles. sql/sql_profile.cc: No longer use the thread's query_id to determine when we flip to a new statement. Some status statements are set to be NULL in the server. We don't log those, as it doesn't fit this style of profiling yet. Rewrite the parser code to be more active and legible. Relying on passive/lazy discovery of new queries was buggy. Add a bogus status change before ending a profile, so that the previous real status has a endpoint. Emit source reference of the start of the span-of-time instead of the end of it. sql/sql_profile.h: Store the server_query_id at instantiation time for a new query. Rewrite the parser code to be more active. Relying on passive/lazy discovery of new queries was buggy. Name first state to more honestly describe the state. We don't really know of initialization that will follow. sql/sql_show.cc: Update comment to note the decidedly weird field_length behavior on Decimal types in information_schema.

* Changing the state of whether we're recording profiling informationunknown2007-04-061-3/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. If profiling was toggled in this query, then don't store this query profile. sql/sql_profile.h: Keep track of whether profiling is on.
* Unreported minor bug: We start numbering query IDs at zero, whichunknown2007-04-031-2/+2
| | | | | | | | | | | | | | | | | | is a special case in "SHOW PROFILE FOR QUERY n". No one can get the zero item (which is always the statement that turns on profiling), 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 value of zero. Unrelated, but looks similar: don't use -1 to initialize an unsigned integer field. That causes warnings in some environments.
* Backport:unknown2007-04-031-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | B-g#27501: 5.0 significantly more sys ("kernel") time than 4.1 \ due to getrusage() calls 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.
* Backport:unknown2007-04-031-46/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | B-g#27060: SQL Profile utility may not be reporting right duration \ for each step Whenever the profiler is reset at the beginning of a query, there's a "hidden" profiling entry that represents that point in time. It has no status description, as those are set by state changes and no such point has yet been encountered. That profiling entry is not in the list of entries generated when we change states. The profiling code had the problem that each step of printing profiling data subtracted the previous "step"'s data, but gave the label to that data of the current step, which is wrong. The label/ state refers to the period beginning with that profiling data, not ending with it. Now, give a label to the first profiling pseudo-entry, so that we have a name to assign to the period that ends with the first state change. Now also use the state name of the previous step in showing the delta values that end with this step. sql/sql_profile.cc: Store a status of "initializing" whenever we construct the first profile entry -- the one that gets reset whenever we're starting a new query, before the server sets a real status. Additionally, associate the previous status with the time period that ends with the current profile entry's stats. Since we need yet another piece of info from the previous profiling entry, take out the piecemeal ways we currently do it and make a general pointer to the whole thing.

| | | | | | | | | | | | | | | | | | | | | | | | | B-g#24795: SHOW PROFILE implementation Don't use memory roots to store profiling information, because memory roots make freeing the data a no-op, and thus long-running processes with profiling turned on the whole time could eventually use all available memory. Instead, use regular heap allocation and deallocation calls to manage profiling data. Replace the leaky List usage with a similar- behaving structure named "Queue". sql/sql_profile.cc: Don't use C++ iterators on our simple Queue implementation. They're not implemented and we don't really need them. Rip out idea of swapping out the thd's mem_root. sql/sql_profile.h: Rip out idea of needing a mem_root. Implement a Queue that looks and behaves very similarly to memroot- using List.

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. --- Merge zippy.cornsilk.net:/home/cmiller/work/mysql/mysql-5.0-community-3--bug24795 into zippy.cornsilk.net:/home/cmiller/work/mysql/mysql-5.0-community --- Fix merge problems. --- Fixed one bug in the query_source being NULL.
