GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License along
with this program; if not, write to the Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License.

# Change history for the MySQL sys schema
## 1.5.1 (07/07/16)
### Improvements
* A `quote_identifier` function was added, which can be used to properly backtick identifier names
* The `Tls_version` column was added to the output from the `mysql.slave_master_info` table, from the `diagnostics` procedure (backported from 5.7 upstream change)
### Bug Fixes
* MySQL Bug #77853 / Oracle Bug #21512106 - The `format_path` function did not consider directory boundaries when comparing variables to paths - it now does. Also fixed to no longer translate backslashes within Windows paths to forward slash
* Oracle Bug #21663578 - Fixed an instability within the sysschema.v_schema_tables_with_full_table_scans test
* Oracle Bug #21970078 - The host_summary view could fail with a division by zero error
* MySQL Bug #78874 / Oracle Bug #22066096 - The `ps_setup_show_enabled` procedure showed all rows for the `performance_schema.setup_objects` table, rather than only those that are enabled
* MySQL Bug #80569 / Oracle Bug #22848110 - The `max_latency` column for the `host_summary_by_statement_latency` view incorrectly showed the SUM of latency
* MySQL Bug #80833 / Oracle Bug #22988461 - The `pages_hashed` and `pages_old` columns within the `innodb_buffer_stats_by_schema` and `innodb_buffer_stats_by_table` views were calculated incorrectly (**Contributed by Tsubasa Tanaka**)
* MySQL Bug #78823 / Oracle Bug #22011361 - The `create_synonym_db` procedure failed when using reserved words as the synonym name (this change also introduced the `quote_identifier` function mentioned above **Contriubuted by Paul Dubois**)
* MySQL Bug #81564 / Oracle Bug #23335880 - The `ps_setup_show_enabled` and `ps_setup_show_disabled` procedures were fixed to:
** Show `user@host` instead of `host@user` for accounts
** Fixed the column header for `disabled_users` within `ps_setup_show_disabled`
** Explicitly ordered all output for test stability
** Show disabled users for 5.7.6+
* Oracle Bug #21970806 - The `sysschema.fn_ps_thread_trx_info` test was unstable
* Oracle Bug #23621189 - The `ps_trace_statement_digest` procedure ran EXPLAIN incorrectly in certain cases (such as on a SHOW statement, no query being specified, or not having a full qualified table), the procedure now catches these issues and ignores them
## 1.5.0 (11/09/15)
### Improvements
* The `format_bytes` function now shows no decimal places when outputting a simple bytes value
* The `processlist`/`x$processlist` views where improved, changes include:
* The `pid` and `program_name` of the connection are shown, if set within the `performance_schema.session_connect_attrs` table (**Contributed by Daniël van Eeden**)
* Issue #50 - The current statement progress is reported via the new stage progress reporting within Performance Schema stages within 5.7 (such as ALTER TABLE progress reporting)
* Issue #60 - A new `statement_latency` column was added to all versions, which reports the current statement latency with picosecond precision from the `performance_schema.events_statements_current` table, when enabled
* Some transaction information was exposed, with the `trx_latency` (for the current or last transaction depending on `trx_state`), `trx_state` (ACTIVE, COMMITTED, ROLLED BACK), and `trx_autocommit` (YES/NO) columns
* A new `metrics` view has been added. On 5.7 this provides a union view of the performance_schema.global_status and information_schema.innodb_metrics tables, along with P_S memory and the current time, as a single metrics output. On 5.6 it provides a union view of the information_schema.global_status and information_schema.innodb_metrics tables, along with the current time. (**Contributed by Jesper Wisborg Krogh**)
* New `session`/`x$session` views have been added, which give the same output as the `processlist` view counterparts, but filtered to only show foreground connections (**Contributed by Morgan Tocker**)
* A new `session_ssl_status` view was added, which shows the SSL version, ciper and session resuse statistics for each connection (**Contributed by Daniël van Eeden**)
* A new `schema_auto_increment_columns` view was added, that shows statistics on each auto_incrment within the instance, including the `auto_increment_ratio`, so you can easily monitor how full specific auto_increment columns are (**Contributed by Shlomi Noach**)
* A new `schema_redundant_indexes` view was added, that shows indexes made redundant (or duplicated) by other more dominant indexes. Also includes the the helper view `x$schema_flattened_keys`. (**Contributed by Shlomi Noach**)
* New `schema_table_lock_waits`/`x$schema_table_lock_waits` views have been added, which show any sessions that are waiting for table level metadata locks, and the sessions that are blocking them. Resolves Git Issue #57, inspired by the suggestion from Daniël van Eeden
* The `innodb_lock_waits` view had the following columns added to it, following a manually merged contribution from Shlomi Noach for a similar view
* `wait_age_secs` - the current row lock wait time in seconds
* `sql_kill_blocking_query` - the "KILL QUERY <connection_id>" command to run to kill the blocking session current statement
* `sql_kill_blocking_connection` - the "KILL <connection_id" command to run to kill the blocking session
* A new `table_exists` procedure was added, which checks for the existence of table, and if it exists, returns the type (BASE TABLE, VIEW, TEMPORARY) (**Contributed by Jesper Wisborg Krogh**)
* A new `execute_prepared_stmt()` procedure was added, which takes a SQL statement as an input variable and executes it as a prepared statement (**Contributed by Jesper Wisborg Krogh**)
* A new `statement_performance_analyzer()` procedure was added, that allows reporting on the statements that are have been running over snapshot periods (**Contributed by Jesper Wisborg Krogh**)
* A new `diagnostics()` procedure was added, which creates a large diagnostics report based upon most of the new instrumentation now available, computed over a configurable number of snapshot intervals (**Contributed by Jesper Wisborg Krogh**)
* A 5.7 specific `ps_trace_thread()` procedure was added, which now shows the hierarchy of transactions and stored routines, as well as statements, stages and waits, if enabled
* Added a new `ps_thread_account()` stored function, that returns the "user@host" account for a given Performance Schema thread id
* Added a new `ps_thread_trx_info()` stored function which outputs, for a given thread id, the transactions, and statements that those transactions have executed, as a JSON object
* Added new `list_add()` and `list_drop()` stored functions, that take a string csv list, and either add or remove items from that list respectively. Can be used to easily update variables that take such lists, like `sql_mode`.
* The `ps_thread_id` stored function now returns the thread id for the current connection if NULL is passed for the in_connection_id parameter
* Added a new `version_major()` stored function, which returns the major version of MySQL Server (**Contributed by Jesper Wisborg Krogh**)
* Added a new `version_minor()` stored function, which returns the minor (release series) version of MySQL Server (**Contributed by Jesper Wisborg Krogh**)
* Added a new `version_patch()` stored function, which returns the patch release version of MySQL Server (**Contributed by Jesper Wisborg Krogh**)
* The `ps_is_account_enabled` function was updated to take a VARCHAR(32) user input on 5.7, as a part of WL#2284
* The generate_sql_file.sh script had a number of improvements:
* Generated files are now output in to a "gen" directory, that is ignored by git
* Added using a new default "mysql.sys@localhost" user (that has the account locked) for the MySQL 5.7+ integration as the DEFINER for all objects
* Added a warning to the top of the generated integration file to also submit changes to the sys project
* Improved the the option of skipping binary logs, so that all routines can load as well - those that used SET sql_log_bin will now select a warning when being used instead of setting the option
### Bug Fixes
* Git Issue #51 - Fixed the `generate_sql_file.sh` script to also replace the definer in the before_setup.sql output
* Git Issue #52 - Removed apostrophe from the `format_statement` function comment because TOAD no likey
* Git Issue #56 - Installation failed on 5.6 with ONLY_FULL_GROUP_BY enabled
* Git Issue #76 - Fixes for the new show_compatibility_56 variable. 5.7 versions of the `format_path()` function and `ps_check_lost_instrumentation` view were added, that use performance_schema.global_status/global_variables instead of information_schema.global_status/global_variables
* Git Issue #79 - Fixed grammar within `statements_with_runtimes_in_95th_percentile` view descriptions
* Oracle Bug #21484593 / Oracle Bug #21281955 - The `format_path()` function incorrectly took and returned a VARCHAR(260) instead of VARCHAR(512) (as the underlying is exposed as in Performance Schema) causing sporadic test failures
* Oracle Bug #21550271 - Fixed the `ps_setup_reset_to_default` for 5.7 with the addition of the new `history` column on the `performance_schema.setup_actors` table
* Oracle Bug #21550054 - It is possible that the views can show data that overflows when aggregating very large values, reset all statistics before each test to ensure no overflows
* Oracle Bug #21647101 - Fixed the `ps_is_instrument_default_enabed` and `ps_is_instrument_default_timed` to take in to account the new instruments added within 5.7
* MySQL Bug #77848 - Added the missing ps_setup_instruments_cleanup.inc
* Fixed the `ps_setup_reset_to_default()` procedure to also set the new `ENABLED` column within `performance_schema.setup_actors` within 5.7
* The `user_summary_by_file_io`/`x$user_summary_by_file_io` and `host_summary_by_file_io`/`x$host_summary_by_file_io` tables were incorrectly aggregating all wait events, not just `wait/io/file/%`
### Implementation Details
* Tests were improved via 5.7 integration
* Template files were added for stored procedures and functions
* Improved the sys_config_cleanup.inc procedure in tests to be able to reset the sys_config table completely (including the set_by column to NULL). The triggers can now be set to not update the column by setting the @sys.ignore_sys_config_triggers user variable to true
## 1.4.0 (09/03/2015)
### Backwards Incompatible Changes
* The `memory_global_by_current_allocated` views were renamed to `memory_global_by_current_bytes` for consistency with the other memory views
* The `ps_setup_enable_consumers` procedure was renamed to `ps_setup_disable_consumer` for naming consistency (everything is now singular, not plural)
* The `format_time` function displayed values in minutes incorrectly, it now rounds to minutes, and uses an 'm' suffix, like the rest of the units
### Improvements
* The beginnings of a mysql-test suite have been added
* The `innodb_lock_waits`/`x$innodb_lock_waits` views were improved (**Contributions by both Jesper Wisborg Krogh and Mark Matthews**)
* Added the `wait_started`, `wait_age`, `waiting_trx_started` `waiting_trx_age`, `waiting_trx_rows_locked` and `waiting_trx_rows_modified` columns for waiting transactions
* Added the `blocking_trx_started`, `blocking_trx_age`, `blocking_trx_rows_locked` and `blocking_trx_rows_modified` for blocking transactions
* Order the result set so the oldest lock waits are first
* The `waiting_table` and `waiting_index` were always the same as the `blocking_table` and `blocking_index`. So the blocking_% columns have been removed and the waiting_% columns have been renamed to locked_%
* The `waiting_lock_type` and `blocking_lock_type` were also always the same. So these were removed and replaced with a single `locked_type` column
* Renamed the `waiting_thread` and `blocking_thread` to `waiting_pid` and `blocking_pid` respectively to avoid confusion with the threads from the Performance Schema.
* Added the `sys_get_config` function, used to get configuration parameters from the `sys_config` table - primarily from other sys objects, but can be used individually (**Contributed by Jesper Wisborg Krogh**)
* Add an option to generate_sql_file.sh to generate a mysql_install_db / mysqld --initialize format friendly file
* Added the `ps_is_thread_instrumented` function, to check whether a specified thread is instrumented within Performance Schema
* Added the `ps_is_consumer_enabled` function, to check whether a specified consumer is enabled within Performance Schema (**Contributed by Jesper Wisborg Krogh**)
* Added some further replacements to the `format_path` function (`slave_load_tmpdir`, `innodb_data_home_dir`, `innodb_log_group_home_dir` and `innodb_undo_directory`)
### Bug Fixes
* The 5.6 `host_summary` and `x$host_summary` views incorrectly had the column with `COUNT(DISTINCT accounts.user)` named `unique_hosts` instead of `unique_users` (**Contributed by Jesper Wisborg Krogh**)
* Both the `format_time` and `format_bytes` took a BIGINT as input, and output VARCHAR, but BIGINT could be too small for aggregated values for the inputs. Now both functions both use TEXT as their input (Issue #34, Issue #38)
* The `format_time` function displayed values in minutes incorrectly, it now rounds to minutes, and uses an 'm' suffix, like the rest of the units
* The `sys_config` related triggers had no DEFINER clause set
* The `ps_setup_disable_thread` procedure always disabled the current thread and was ignoring the connection id given as an argument (**Contributed by Jesper Wisborg Krogh**)
* The `ps_trace_thread` procedure had an incorrect calculation of how long the procedure has been running (**Contributed by Jesper Wisborg Krogh**)
### Implementation Details
Various changes were made to allow better generation of integration sql files:
* The formatting for all comments has been standardized on -- line comments. C-style /* comments */ have been removed
* Issue #35 had one instance of this resolved in this release (**Contributed by Joe Grasse**), but the entire code base has now been done
* Each object has been created within it's own file. No longer do x$ views live with their non-x$ counterparts
* DELIMITERs were standardized to $$
## 1.3.0 (23/10/2014)
### Improvements
* Added an `innodb_lock_waits` set of views, showing each thread that is waiting on a lock within InnoDB, and the blocking thread lock information (**Contributed by Jesper Wisborg Krogh**)
### Bug Fixes
* Fixed broken `host_summary_by_stages` views, broken with a last minute change before the 1.2.0 release that went unnoticed (facepalm)
## 1.2.0 (22/10/2014)
### Backwards Incompatible Changes
* The `host_summary_by_stages` and `user_summary_by_stages` `wait_sum` and `wait_avg` columns were renamed to `total_latency` and `avg_latency` respectively, for consistency.
* The `host_summary_by_file_io_type` and `user_summary_by_file_io_type `latency` column was renamed to `total_latency`, for consistency.
### Improvements
* Made the truncation length for the `format_statement` view configurable
* This includes adding a new persistent `sys_config` table to store the new variable - `statement_truncate_len` - see the README for usage
* Added `total_latency` to the `schema_tables_with_full_table_scans` view, and added an x$ counterpart
* Added `innodb_buffer_free` to the `schema_table_statistics_with_buffer` view, to summarize how much free space is allocated per table in the buffer pool
* The `schema_unused_indexes` view now ignores indexes named `PRIMARY` (primary keys)
* Added `rows_affected` and `rows_affected_avg` stats to the `statement_analysis` views
* The `statements_with_full_table_scans` view now ignores any SQL that starts with `SHOW`
* Added a script, `generate_sql_file.sh`, that can be used to generate a single SQL file, also allowing substitution of the MySQL user to use, and/or whether the `SET sql_log_bin ...` statements should be omitted.
* This is useful for those using RDS, where the root@localhost user is not accessible, and sql_log_bin is disabled (Issue #5)
* Added a set of `memory_by_thread_by_current_bytes` views, that summarize memory usage per thread with MySQL 5.7's memory instrumentation
* Improved each of the host specific views to return aggregate values for `background` threads, instead of ignoring them, in the same way as the user summary views
### Bug Fixes
* Added the missing `memory_by_host` view for MySQL 5.7
* Added missing space for hour notation within the `format_time` function
* Fixed views affected by MySQL 5.7 ONLY_FULL_GROUP_BY and functional dependency changes
## 1.1.0 (04/09/2014)
### Improvements
* Added host summary views, which have the same structure as the user summary views, but aggregated by host instead (**Contributed by Arnaud Adant**)
* `host_summary`
* `host_summary_by_file_io_type`
* `host_summary_by_file_io`
* `host_summary_by_statement_type`
* `host_summary_by_statement_latency`
* `host_summary_by_stages`
* `waits_by_host_by_latency`
* Added functions which return instruments are either enabled, or timed by default (#15) (**Contributed by Jesper Wisborg Krogh**)
* `ps_is_instrument_default_enabled`
* `ps_is_instrument_default_timed`
* Added a `ps_thread_id` function, which returns the thread_id value exposed within performance_schema for the current connection (**Contributed by Jesper Wisborg Krogh**)
* Improved each of the user specific views to return aggregate values for `background` threads, instead of ignoring them (**Contributed by Joe Grasse**)
* Optimized the `schema_table_statistics` and `schema_table_statistics_with_buffer` views, to use a new view that will get materialized (`x$ps_schema_table_statistics_io`), along with the changes to the RETURN types for `extract_schema_from_file_name` and `extract_table_from_file_name`, this results in a significant performance improvement - in one test changing the run time from 14 minutes to 20 seconds. (**Conceived by Roy Lyseng, Mark Leith and Jesper Wisborg Krogh, implemented and contributed by Jesper Wisborg Krogh**)
### Bug Fixes
* Removed unintentially committed sys_56_rds.sql file (See Issue #5, which is still outstanding)
* Fixed the `ps_trace_statement_digest` and `ps_trace_thread` procedures to properly set sql_log_bin, and reset the thread INSTRUMENTED value correctly (**Contributed by Jesper Wisborg Krogh**)
* Removed various sql_log_bin disabling from other procedures that no longer require it - DML against the performance_schema data is no longer replicated (**Contributed by Jesper Wisborg Krogh**)
* Fixed EXPLAIN within `ps_trace_statement_digest` procedure (**Contributed by Jesper Wisborg Krogh**)
* Fixed the datatype for the `thd_id` variable within the `ps_thread_stack` procedure (**Contributed by Jesper Wisborg Krogh**)
* Fixed datatypes used for temporary tables within the `ps_trace_statement_digest` procedure (**Contributed by Jesper Wisborg Krogh**)
* Fixed the RETURN datatype `extract_schema_from_file_name` and `extract_table_from_file_name` to return a VARCHAR(64) (**Contributed by Jesper Wisborg Krogh**)
* Added events_transactions_current to the default enabled consumers in 5.7 (#25)
## 1.0.1 (23/05/2014)
### Improvements
* Added procedures to enable / disable Performance Schema consumers. (**Contributed by the MySQL QA Team**)
* `ps_setup_disable_consumers(<LIKE string>)` allows disabling any consumers matching the LIKE string.
* `ps_setup_enable_consumers(<LIKE string>)` allows enabling any consumers matching the LIKE string.
* Added procedures to show both enabled and disbled consumers or instruments individually, these are more useful for tooling than the `ps_setup_show_enabled`/`ps_setup_show_disabled` procedures which show all configuration in multiple result sets. (**Contributed by the MySQL QA Team**)
* `ps_setup_show_disabled_consumers` shows only disabled consumers.
* `ps_setup_show_disabled_instruments` shows only disabled instruments.
* `ps_setup_show_enabled_consumers` shows only enabled consumers.
* `ps_setup_show_enabled_instruments` shows only enabled instruments.
### Bug Fixes
* Running the installation scripts sometimes failed because of the comment format. (#1) (**Contributed by Joe Grasse**)
* Some views did not work with the ERROR_FOR_DIVISION_BY_ZERO SQL mode. (#6) (**Contributed by Joe Grasse**)
* On Windows the `ps_thread_stack()` stored function failed to escape file path backslashes correctly within the JSON output.

To configure the length to truncate the statement to by default, update the `statement_truncate_len`
variable with `sys_config` table to a different value. Alternatively, to change it just for just
your particular session, use `SET @sys.statement_truncate_len := <some new value>`.
Useful for printing statement related data from Performance Schema from
the command line.
Parameters
-----------
statement (LONGTEXT):
The statement to format.
Returns
-----------
LONGTEXT
Example
-----------
mysql> SELECT sys.format_statement(digest_text)
-> FROM performance_schema.events_statements_summary_by_digest
-> ORDER by sum_timer_wait DESC limit 5;

DROP FUNCTION IF EXISTS ps_thread_trx_info;
DELIMITER $$
CREATE DEFINER='root'@'localhost' FUNCTION ps_thread_trx_info (
in_thread_id BIGINT UNSIGNED
) RETURNS LONGTEXT
COMMENT '
Description
-----------
Returns a JSON object with info on the given threads current transaction,
and the statements it has already executed, derived from the
performance_schema.events_transactions_current and
performance_schema.events_statements_history tables (so the consumers
for these also have to be enabled within Performance Schema to get full
data in the object).
When the output exceeds the default truncation length (65535), a JSON error
object is returned, such as:
{ "error": "Trx info truncated: Row 6 was cut by GROUP_CONCAT()" }
Similar error objects are returned for other warnings/and exceptions raised
when calling the function.
The max length of the output of this function can be controlled with the
ps_thread_trx_info.max_length variable set via sys_config, or the
@sys.ps_thread_trx_info.max_length user variable, as appropriate.
Parameters
-----------
in_thread_id (BIGINT UNSIGNED):
The id of the thread to return the transaction info for.

in_default_value VARCHAR(128)

RETURNS VARCHAR(128)
COMMENT '
Description
-----------
Returns the value for the requested variable using the following logic:
1. If the option exists in sys.sys_config return the value from there.
2. Else fall back on the provided default value.
Notes for using sys_get_config():
* If the default value argument to sys_get_config() is NULL and case 2. is reached, NULL is returned.
It is then expected that the caller is able to handle NULL for the given configuration option.
* The convention is to name the user variables @sys.<name of variable>. It is <name of variable> that
is stored in the sys_config table and is what is expected as the argument to sys_get_config().
* If you want to check whether the configuration option has already been set and if not assign with
the return value of sys_get_config() you can use IFNULL(...) (see example below). However this should
not be done inside a loop (e.g. for each row in a result set) as for repeated calls where assignment
is only needed in the first iteration using IFNULL(...) is expected to be significantly slower than
using an IF (...) THEN ... END IF; block (see example below).
Parameters
-----------
in_variable_name (VARCHAR(128)):
The name of the config option to return the value for.
in_default_value (VARCHAR(128)):
The default value to return if the variable does not exist in sys.sys_config.
Returns
-----------
VARCHAR(128)
Example
-----------
-- Get the configuration value from sys.sys_config falling back on 128 if the option is not present in the table.

DROP PROCEDURE IF EXISTS ps_setup_save;
DELIMITER $$
CREATE DEFINER='root'@'localhost' PROCEDURE ps_setup_save (
IN in_timeout INT
)
COMMENT '
Description
-----------
Saves the current configuration of Performance Schema,
so that you can alter the setup for debugging purposes,
but restore it to a previous state.
Use the companion procedure - ps_setup_reload_saved(), to
restore the saved config.
The named lock "sys.ps_setup_save" is taken before the
current configuration is saved. If the attempt to get the named
lock times out, an error occurs.
The lock is released after the settings have been restored by
calling ps_setup_reload_saved().
Requires the SUPER privilege for "SET sql_log_bin = 0;".
Parameters
-----------
in_timeout INT
The timeout in seconds used when trying to obtain the lock.
A negative timeout means infinite timeout.
Example
-----------
mysql> CALL sys.ps_setup_save(-1);
Query OK, 0 rows affected (0.08 sec)
mysql> UPDATE performance_schema.setup_instruments

DROP PROCEDURE IF EXISTS ps_trace_statement_digest;
DELIMITER $$
CREATE DEFINER='root'@'localhost' PROCEDURE ps_trace_statement_digest (
IN in_digest VARCHAR(32),
IN in_runtime INT,
IN in_interval DECIMAL(2,2),
IN in_start_fresh BOOLEAN,
IN in_auto_enable BOOLEAN
)
COMMENT '
Description
-----------
Traces all instrumentation within Performance Schema for a specific
Statement Digest.
When finding a statement of interest within the
performance_schema.events_statements_summary_by_digest table, feed
the DIGEST MD5 value in to this procedure, set how long to poll for,
and at what interval to poll, and it will generate a report of all
statistics tracked within Performance Schema for that digest for the
interval.
It will also attempt to generate an EXPLAIN for the longest running
example of the digest during the interval. Note this may fail, as:
* Performance Schema truncates long SQL_TEXT values (and hence the
EXPLAIN will fail due to parse errors)
* the default schema is sys (so tables that are not fully qualified
in the query may not be found)
* some queries such as SHOW are not supported in EXPLAIN.
When the EXPLAIN fails, the error will be ignored and no EXPLAIN
output generated.
Requires the SUPER privilege for "SET sql_log_bin = 0;".
Parameters
-----------
in_digest (VARCHAR(32)):
The statement digest identifier you would like to analyze
in_runtime (INT):
The number of seconds to run analysis for
in_interval (DECIMAL(2,2)):
The interval (in seconds, may be fractional) at which to try
and take snapshots
in_start_fresh (BOOLEAN):
Whether to TRUNCATE the events_statements_history_long and
events_stages_history_long tables before starting
in_auto_enable (BOOLEAN):
Whether to automatically turn on required consumers
Example
-----------
mysql> call ps_trace_statement_digest(\'891ec6860f98ba46d89dd20b0c03652c\', 10, 0.1, true, true);

Description
-----------
Dumps all data within Performance Schema for an instrumented thread,
to create a DOT formatted graph file.
Each resultset returned from the procedure should be used for a complete graph
Requires the SUPER privilege for "SET sql_log_bin = 0;".
Parameters
-----------
in_thread_id (BIGINT UNSIGNED):
The thread that you would like a stack trace for
in_outfile (VARCHAR(255)):
The filename the dot file will be written to
in_max_runtime (DECIMAL(20,2)):
The maximum time to keep collecting data.
Use NULL to get the default which is 60 seconds.
in_interval (DECIMAL(20,2)):
How long to sleep between data collections.
Use NULL to get the default which is 1 second.
in_start_fresh (BOOLEAN):
Whether to reset all Performance Schema data before tracing.
in_auto_setup (BOOLEAN):
Whether to disable all other threads and enable all consumers/instruments.
This will also reset the settings at the end of the run.
in_debug (BOOLEAN):
Whether you would like to include file:lineno in the graph

COMMENT '
Description
-----------
Create a report of the statements running on the server.
The views are calculated based on the overall and/or delta activity.
Requires the SUPER privilege for "SET sql_log_bin = 0;".
Parameters
-----------
in_action (ENUM(''snapshot'', ''overall'', ''delta'', ''create_tmp'', ''create_table'', ''save'', ''cleanup'')):
The action to take. Supported actions are:
* snapshot Store a snapshot. The default is to make a snapshot of the current content of
performance_schema.events_statements_summary_by_digest, but by setting in_table
this can be overwritten to copy the content of the specified table.
The snapshot is stored in the sys.tmp_digests temporary table.
* overall Generate analyzis based on the content specified by in_table. For the overall analyzis,
in_table can be NOW() to use a fresh snapshot. This will overwrite an existing snapshot.
Use NULL for in_table to use the existing snapshot. If in_table IS NULL and no snapshot
exists, a new will be created.
See also in_views and @sys.statement_performance_analyzer.limit.
* delta Generate a delta analysis. The delta will be calculated between the reference table in
in_table and the snapshot. An existing snapshot must exist.
The action uses the sys.tmp_digests_delta temporary table.
See also in_views and @sys.statement_performance_analyzer.limit.
* create_table Create a regular table suitable for storing the snapshot for later use, e.g. for
calculating deltas.
* create_tmp Create a temporary table suitable for storing the snapshot for later use, e.g. for
calculating deltas.
* save Save the snapshot in the table specified by in_table. The table must exists and have
the correct structure.
If no snapshot exists, a new is created.
* cleanup Remove the temporary tables used for the snapshot and delta.
in_table (VARCHAR(129)):
The table argument used for some actions. Use the format ''db1.t1'' or ''t1'' without using any backticks (`)
for quoting. Periods (.) are not supported in the database and table names.
The meaning of the table for each action supporting the argument is:
* snapshot The snapshot is created based on the specified table. Set to NULL or NOW() to use
the current content of performance_schema.events_statements_summary_by_digest.
* overall The table with the content to create the overall analyzis for. The following values
can be used:
- A table name - use the content of that table.
- NOW() - create a fresh snapshot and overwrite the existing snapshot.
- NULL - use the last stored snapshot.
* delta The table name is mandatory and specified the reference view to compare the currently
stored snapshot against. If no snapshot exists, a new will be created.
* create_table The name of the regular table to create.
* create_tmp The name of the temporary table to create.
* save The name of the table to save the currently stored snapshot into.
in_views (SET (''with_runtimes_in_95th_percentile'', ''analysis'', ''with_errors_or_warnings'',
''with_full_table_scans'', ''with_sorting'', ''with_temp_tables'', ''custom''))
Which views to include:
* with_runtimes_in_95th_percentile Based on the sys.statements_with_runtimes_in_95th_percentile view
* analysis Based on the sys.statement_analysis view
* with_errors_or_warnings Based on the sys.statements_with_errors_or_warnings view
* with_full_table_scans Based on the sys.statements_with_full_table_scans view
* with_sorting Based on the sys.statements_with_sorting view
* with_temp_tables Based on the sys.statements_with_temp_tables view
* custom Use a custom view. This view must be specified in @sys.statement_performance_analyzer.view to an existing view or a query
Default is to include all except ''custom''.
Configuration Options
----------------------
sys.statement_performance_analyzer.limit
The maximum number of rows to include for the views that does not have a built-in limit (e.g. the 95th percentile view).
If not set the limit is 100.
sys.statement_performance_analyzer.view
Used together with the ''custom'' view. If the value contains a space, it is considered a query, otherwise it must be
an existing view querying the performance_schema.events_statements_summary_by_digest table. There cannot be any limit
clause including in the query or view definition if @sys.statement_performance_analyzer.limit > 0.
If specifying a view, use the same format as for in_table.
sys.debug
Whether to provide debugging output.
Default is ''OFF''. Set to ''ON'' to include.
Example
--------
To create a report with the queries in the 95th percentile since last truncate of performance_schema.events_statements_summary_by_digest
and the delta for a 1 minute period:
1. Create a temporary table to store the initial snapshot.
2. Create the initial snapshot.
3. Save the initial snapshot in the temporary table.
4. Wait one minute.
5. Create a new snapshot.
6. Perform analyzis based on the new snapshot.
7. Perform analyzis based on the delta between the initial and new snapshots.

DROP PROCEDURE IF EXISTS table_exists;
DELIMITER $$
CREATE DEFINER='root'@'localhost' PROCEDURE table_exists (
IN in_db VARCHAR(64), IN in_table VARCHAR(64),
OUT out_exists ENUM('', 'BASE TABLE', 'VIEW', 'TEMPORARY')
)
COMMENT '
Description
-----------
Tests whether the table specified in in_db and in_table exists either as a regular
table, or as a temporary table. The returned value corresponds to the table that
will be used, so if there''s both a temporary and a permanent table with the given
name, then ''TEMPORARY'' will be returned.
Parameters
-----------
in_db (VARCHAR(64)):
The database name to check for the existance of the table in.
in_table (VARCHAR(64)):
The name of the table to check the existance of.
out_exists ENUM('''', ''BASE TABLE'', ''VIEW'', ''TEMPORARY''):
The return value: whether the table exists. The value is one of:
* '''' - the table does not exist neither as a base table, view, nor temporary table.
* ''BASE TABLE'' - the table name exists as a permanent base table table.
* ''VIEW'' - the table name exists as a view.
* ''TEMPORARY'' - the table name exists as a temporary table.

-- IMPORTANT
-- If you update this view, also update the "5.7+ and the Performance Schema disabled"
-- query in procedures/diagnostics.sql
-- View: metrics
--
-- Creates a union of the following information:
--
-- * performance_schema.global_status
-- * information_schema.INNODB_METRICS
-- * Performance Schema global memory usage information
-- * Current time
--
-- This is the same as the metrics_56 view with the exception that the global status is taken from performance_schema.global_status instead of
-- from the Information Schema. Use this view if the MySQL version is 5.7.6 or later and show_compatibility_56 = OFF.
-- See also https://dev.mysql.com/doc/refman/5.7/en/server-system-variables.html#sysvar_show_compatibility_56
--
-- For view has the following columns:
--
-- * Variable_name: The name of the variable
-- * Variable_value: The value of the variable
-- * Type: The type of the variable. This will depend on the source, e.g. Global Status, InnoDB Metrics - ..., etc.
-- * Enabled: Whether the variable is enabled or not. Possible values are 'YES', 'NO', 'PARTIAL'.
-- PARTIAL is currently only supported for the memory usage variables and means some but not all of the memory/% instruments
-- are enabled.
