unknown	f8ccbcc431	Correct complaints of reviewers and clean up test. mysql-test/r/profiling.result: Remove unnecessary verbosity. Remove section of test that is impossible to test with PS protocol. mysql-test/t/profiling.test: Remove unnecessary verbosity. Remove section of test that is impossible to test with PS protocol. sql/sql_profile.h: Make bit flags unsigned ints.	18 years ago
unknown	69aee07373	Rewrite profiler code to be easier to maintain and less buggy. 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.	18 years ago
unknown	fc70ac4627	Sundry changes to fix merge problems. Most of these are duplicated in 5.0-community, but pulling to merge was very hard. sql/mysql_priv.h: Add new extern "C" qualification to set_thd_proc_info(). Fix typo in merge. sql/mysqld.cc: Replace obselete gptr with uchar* . Add missing #endif from merge problem. sql/set_var.cc: Include new parameter to user variable contruction. sql/sql_cache.cc: Remove duplicate line from merge problem. sql/sql_profile.cc: struct st_table_list is now typedef'd to a new name. ST_FIELD_INFO now includes a new member, a pointer to an open_table function. sql/sql_profile.h: struct st_table_list is now typedef'd to a new name.	18 years ago
unknown	5008a4e720	Track typedef'd struct. Name changed in Enterprise tree, but community-exclusive file also referred to struct. sql/sql_profile.cc: Track typedef'd struct. sql/sql_profile.h: Track typedef'd struct.	18 years ago
unknown	358b942b20	Unify profiling SHOW code and INFORMATION_SCHEMA code for profiling. Also, Bug#26938: profiling client hang if used before enabled In the SHOW command, not sending header data because we had no rows to send was a protocol violation. Porting the SHOW PROFILE command to use the Information Schema table avoids that problem. mysql-test/r/profiling.result: Add headers of pre-profile SHOW test. mysql-test/t/profiling.test: Verify that the protocol isn't violated if we ask for profiling info before profiling has recorded anything. sql/sql_parse.cc: Remove SQLCOM_SHOW_PROFILE and add a I_S schema table entry. sql/sql_profile.cc: Add SHOW column-names and a new function that takes profile options set in the parser and packs a list of selected fields from the I_S table implementation. sql/sql_profile.h: Remove unused functions and add a new function. sql/sql_show.cc: Add a pointer to the function that selects fields from I_S table for SHOW command. sql/sql_yacc.yy: Prepare an I_S table for SHOW PROFILE. sql/table.h: Rename to match the intention.	19 years ago
unknown	0901dbc583	Fix up merge. Some macros are now functions. Some functions are renamed. Some new THD proc_info states are new. Directories must be encountered in make in a specific order, to have symlinks already set. Move community-server-specific tests into own tests, so that we can exempt them from testing on enterprise servers. BitKeeper/deleted/.del-profiling.inc: Delete: mysql-test/include/profiling.inc BitKeeper/deleted/.del-profiling.require: Delete: mysql-test/r/profiling.require configure.in: Set a new order of sql_client_dirs, so that the make directory traversal doesn't miss symlink dependencies. mysql-test/r/not_embedded_server.result: Account for new "executing" state. mysql-test/t/information_schema.test: Move community-feature test to another test file. mysql-test/t/profiling.test: Make test more generic to community features. sql/lex.h: Add symbol lost in manual merge. sql/mysql_priv.h: Insert a preprocessor layer between setting the caller and the function that sets the thread state, so we can get caller information. sql/mysqld.cc: Add new server variable "have_community_features". sql/set_var.cc: Add new server variable "have_community_features". sql/sql_class.cc: Insert a preprocessor layer between setting the caller and the function that sets the thread state, so we can get caller information. sql/sql_profile.cc: Function name change, my_strndup() sql/sql_profile.h: Insert a preprocessor layer between setting the caller and the function that sets the thread state, so we can get caller information. mysql-test/include/have_community_features.inc: New BitKeeper file ``mysql-test/include/have_community_features.inc'' mysql-test/r/have_community_features.require: New BitKeeper file ``mysql-test/r/have_community_features.require'' mysql-test/r/variables+c.result: New BitKeeper file ``mysql-test/r/variables+c.result'' mysql-test/t/variables+c.test: New BitKeeper file ``mysql-test/t/variables+c.test''	19 years ago
unknown	2b4a895613	Wrap code specific to the comunity-server in additional CPP #ifdef . Add a new autoconf paremeter --{en,dis}able-community-features . The default is disable for enterprise servers. Though this is a 5.0 tree, it is only to be merged into the 5.0-community tree and the global 5.1 tree, never to the 5.0-enterprise tree. configure.in: Add a new configure parameter, --enable-community-features for community features. mysql-test/t/profiling.test: Add testing for whether profiling is enabled or not. sql/mysqld.cc: Add additional "COMMUNITY_SERVER" cpp definition test. sql/set_var.cc: Add additional "COMMUNITY_SERVER" cpp definition test. sql/sql_class.cc: Add additional "COMMUNITY_SERVER" cpp definition test. sql/sql_class.h: Add additional "COMMUNITY_SERVER" cpp definition test. sql/sql_parse.cc: Add additional "COMMUNITY_SERVER" cpp definition test. sql/sql_prepare.cc: Add additional "COMMUNITY_SERVER" cpp definition test. sql/sql_profile.cc: Add additional "COMMUNITY_SERVER" cpp definition test. sql/sql_profile.h: Add additional "COMMUNITY_SERVER" cpp definition test. sql/sql_show.cc: Add "COMMUNITY_SERVER" cpp definition test. mysql-test/include/profiling.inc: Add testing for whether profiling is enabled or not. mysql-test/r/profiling.require: Add testing for whether profiling is enabled or not.	19 years ago
unknown	fcb52609e4	Changing the state of whether we're recording profiling information 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.	19 years ago
unknown	698d98bea0	Backport: 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.	19 years ago
unknown	37dd1c9de4	Patch to release clone. Fixes two post-pushbuild discovered failures. Expand float size to avoid assert()ion failures. "_db_func_" isn't a known linked object on some platforms, possibly because it is occasionaly shadowed by DBUG variables. Avoid that confusion. sql/sql_profile.cc: Expand float size to avoid assert()ion failures. "_db_func_" isn't a known linked object on some platforms, possibly because it is occasionaly shadowed by DBUG variables. Avoid that confusion. sql/sql_profile.h: "_db_func_" isn't a known linked object on some platforms, possibly because it is occasionaly shadowed by DBUG variables. Avoid that confusion.	19 years ago
unknown	9e2fd8caad	Some changes suggested Serg, from message <20070223210659.GA24202@janus.mylan> configure.in: Use smarter autoconf help macro. sql/set_var.cc: Make a local variable static. sql/sql_lex.cc: Don't include CPP condition where it saves little time and decreases legibility. sql/sql_parse.cc: Use the name of the query in the error, instead of describing the feature. sql/sql_profile.cc: Update copyright. Make I_S schema table columns uppercase. sql/sql_profile.h: Update copyright. sql/sql_select.cc: Chagne tab indentation to spaces.	19 years ago
unknown	607c224969	Prevent bugs by making DBUG_* expressions syntactically equivalent to a single statement. --- 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. --- 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. Updated test results. --- Include more thorough profiling tests. Improve support for prepared statements. Use session-specific query IDs, starting at zero. --- Selecting from I_S.profiling is no longer quashed in profiling, as requested by Giuseppe. Limit the size of captured query text. No longer log queries that are zero length. BitKeeper/deleted/.del-profile.result: Rename: mysql-test/r/profile.result -> BitKeeper/deleted/.del-profile.result BitKeeper/deleted/.del-profile.test: Rename: mysql-test/t/profile.test -> BitKeeper/deleted/.del-profile.test BitKeeper/deleted/.del-sql_profile.cc: Rename: sql/sql_profile.cc -> BitKeeper/deleted/.del-sql_profile.cc BitKeeper/deleted/.del-sql_profile.h: Rename: sql/sql_profile.h -> BitKeeper/deleted/.del-sql_profile.h configure.in: Add a configure-time option to enable/disable query profiling.
