# To use this script you will need to have installed package python-pyside which
# provides LGPL-licensed Python bindings for Qt.  You will also need the package
# libqt4-sql-psql for Qt postgresql support.
#
# The script assumes postgresql is running on the local machine and that the
# user has postgresql permissions to create databases. Examples of installing
# postgresql and adding such a user are:
#
# fedora:
#
#	$ sudo yum install postgresql postgresql-server python-pyside qt-postgresql
#	$ sudo su - postgres -c initdb
#	$ sudo service postgresql start
#	$ sudo su - postgres
#	$ createuser <your user id here>
#	Shall the new role be a superuser? (y/n) y
#
# ubuntu:
#
#	$ sudo apt-get install postgresql python-pyside.qtsql libqt4-sql-psql
#	$ sudo su - postgres
#	$ createuser -s <your user id here>
#
# An example of using this script with Intel PT:
#
#	$ perf record -e intel_pt//u ls
#	$ perf script -s ~/libexec/perf-core/scripts/python/export-to-postgresql.py pt_example branches calls

#	2015-05-29 12:49:28.655683 Adding foreign keys
#	2015-05-29 12:49:29.365350 Done
#
# To browse the database, psql can be used e.g.
#
#	$ psql pt_example
#	pt_example=# select * from samples_view where id < 100;
#	pt_example=# \d+
#	pt_example=# \d+ samples_view
#	pt_example=# \q
#
# An example of using the database is provided by the script
# exported-sql-viewer.py.  Refer to that script for details.
#
# Tables:
#
#	The tables largely correspond to perf tools' data structures.  They are largely self-explanatory.
#
#	samples
#
#		'samples' is the main table. It represents what instruction was executing at a point in time
#		when something (a selected event) happened.  The memory address is the instruction pointer or 'ip'.
#
#	calls
#
#		'calls' represents function calls and is related to 'samples' by 'call_id' and 'return_id'.
#		'calls' is only created when the 'calls' option to this script is specified.
#
#	call_paths
#
#		'call_paths' represents all the call stacks.  Each 'call' has an associated record in 'call_paths'.
#		'calls_paths' is only created when the 'calls' option to this script is specified.
#
#	branch_types
#
#		'branch_types' provides descriptions for each type of branch.
#
#	comm_threads
#
#		'comm_threads' shows how 'comms' relates to 'threads'.
#
#	comms
#
#		'comms' contains a record for each 'comm' - the name given to the executable that is running.
#
#	dsos
#
#		'dsos' contains a record for each executable file or library.
#
#	machines
#
#		'machines' can be used to distinguish virtual machines if virtualization is supported.
#
#	selected_events
#
#		'selected_events' contains a record for each kind of event that has been sampled.
#
#	symbols
#
#		'symbols' contains a record for each symbol.  Only symbols that have samples are present.
#
#	threads
#
#		'threads' contains a record for each thread.
#
# Views:
#
#	Most of the tables have views for more friendly display.  The views are:
#
#		calls_view
#		call_paths_view
#		comm_threads_view
#		dsos_view
#		machines_view
#		samples_view
#		symbols_view
#		threads_view
#
# More examples of browsing the database with psql:
#   Note that some of the examples are not the most optimal SQL query.
#   Note that call information is only available if the script's 'calls' option has been used.
#
#	Top 10 function calls (not aggregated by symbol):
#
#		SELECT * FROM calls_view ORDER BY elapsed_time DESC LIMIT 10;
#
#	Top 10 function calls (aggregated by symbol):
#
#		SELECT symbol_id,(SELECT name FROM symbols WHERE id = symbol_id) AS symbol,
#			SUM(elapsed_time) AS tot_elapsed_time,SUM(branch_count) AS tot_branch_count
#			FROM calls_view GROUP BY symbol_id ORDER BY tot_elapsed_time DESC LIMIT 10;
#
#		Note that the branch count gives a rough estimation of cpu usage, so functions
#		that took a long time but have a relatively low branch count must have spent time
#		waiting.
#
#	Find symbols by pattern matching on part of the name (e.g. names containing 'alloc'):
#
#		SELECT * FROM symbols_view WHERE name LIKE '%alloc%';
#
#	Top 10 function calls for a specific symbol (e.g. whose symbol_id is 187):
#
#		SELECT * FROM calls_view WHERE symbol_id = 187 ORDER BY elapsed_time DESC LIMIT 10;
#
#	Show function calls made by function in the same context (i.e. same call path) (e.g. one with call_path_id 254):
#
#		SELECT * FROM calls_view WHERE parent_call_path_id = 254;
#
#	Show branches made during a function call (e.g. where call_id is 29357 and return_id is 29370 and tid is 29670)
#
#		SELECT * FROM samples_view WHERE id >= 29357 AND id <= 29370 AND tid = 29670 AND event LIKE 'branches%';
#
#	Show transactions:
#
#		SELECT * FROM samples_view WHERE event = 'transactions';
#
#		Note transaction start has 'in_tx' true whereas, transaction end has 'in_tx' false.
#		Transaction aborts have branch_type_name 'transaction abort'
#
#	Show transaction aborts:
#
#		SELECT * FROM samples_view WHERE event = 'transactions' AND branch_type_name = 'transaction abort';
#
# To print a call stack requires walking the call_paths table.  For example this python script:
#   #!/usr/bin/python2
#
#   import sys
#   from PySide.QtSql import *
#
#   if __name__ == '__main__':
#           if (len(sys.argv) < 3):
