 18# To use this script you will need to have installed package python-pyside which
 19# provides LGPL-licensed Python bindings for Qt.  You will also need the package
 20# libqt4-sql-psql for Qt postgresql support.
 21#
 22# The script assumes postgresql is running on the local machine and that the
 23# user has postgresql permissions to create databases. Examples of installing
 24# postgresql and adding such a user are:
 25#
 26# fedora:
 27#
 28#	$ sudo yum install postgresql postgresql-server python-pyside qt-postgresql
 29#	$ sudo su - postgres -c initdb
 30#	$ sudo service postgresql start
 31#	$ sudo su - postgres
 32#	$ createuser <your user id here>
 33#	Shall the new role be a superuser? (y/n) y
 34#
 35# ubuntu:
 36#
 37#	$ sudo apt-get install postgresql
 38#	$ sudo su - postgres
 39#	$ createuser <your user id here>
 40#	Shall the new role be a superuser? (y/n) y
 41#
 42# An example of using this script with Intel PT:
 43#
 44#	$ perf record -e intel_pt//u ls
 45#	$ perf script -s ~/libexec/perf-core/scripts/python/export-to-postgresql.py pt_example branches calls

 53#
 54# To browse the database, psql can be used e.g.
 55#
 56#	$ psql pt_example
 57#	pt_example=# select * from samples_view where id < 100;
 58#	pt_example=# \d+
 59#	pt_example=# \d+ samples_view
 60#	pt_example=# \q
 61#
 62# An example of using the database is provided by the script
 63# call-graph-from-postgresql.py.  Refer to that script for details.
 64#
 65# Tables:
 66#
 67#	The tables largely correspond to perf tools' data structures.  They are largely self-explanatory.
 68#
 69#	samples
 70#
 71#		'samples' is the main table. It represents what instruction was executing at a point in time
 72#		when something (a selected event) happened.  The memory address is the instruction pointer or 'ip'.
 73#
 74#	calls
 75#
 76#		'calls' represents function calls and is related to 'samples' by 'call_id' and 'return_id'.
 77#		'calls' is only created when the 'calls' option to this script is specified.
 78#
 79#	call_paths
 80#
 81#		'call_paths' represents all the call stacks.  Each 'call' has an associated record in 'call_paths'.
 82#		'calls_paths' is only created when the 'calls' option to this script is specified.
 83#
 84#	branch_types
 85#
 86#		'branch_types' provides descriptions for each type of branch.
 87#
 88#	comm_threads
 89#
 90#		'comm_threads' shows how 'comms' relates to 'threads'.
 91#
 92#	comms
 93#
 94#		'comms' contains a record for each 'comm' - the name given to the executable that is running.
 95#
 96#	dsos
 97#
 98#		'dsos' contains a record for each executable file or library.
 99#
100#	machines
101#
102#		'machines' can be used to distinguish virtual machines if virtualization is supported.
103#
104#	selected_events
105#
106#		'selected_events' contains a record for each kind of event that has been sampled.
107#
108#	symbols
109#
110#		'symbols' contains a record for each symbol.  Only symbols that have samples are present.
111#
112#	threads
113#
114#		'threads' contains a record for each thread.
115#
116# Views:
117#
118#	Most of the tables have views for more friendly display.  The views are:
119#
120#		calls_view
121#		call_paths_view
122#		comm_threads_view
123#		dsos_view
124#		machines_view
125#		samples_view
126#		symbols_view
127#		threads_view
128#
129# More examples of browsing the database with psql:
130#   Note that some of the examples are not the most optimal SQL query.
131#   Note that call information is only available if the script's 'calls' option has been used.
132#
133#	Top 10 function calls (not aggregated by symbol):
134#
135#		SELECT * FROM calls_view ORDER BY elapsed_time DESC LIMIT 10;
136#
137#	Top 10 function calls (aggregated by symbol):
138#
139#		SELECT symbol_id,(SELECT name FROM symbols WHERE id = symbol_id) AS symbol,
140#			SUM(elapsed_time) AS tot_elapsed_time,SUM(branch_count) AS tot_branch_count
141#			FROM calls_view GROUP BY symbol_id ORDER BY tot_elapsed_time DESC LIMIT 10;
142#
143#		Note that the branch count gives a rough estimation of cpu usage, so functions
144#		that took a long time but have a relatively low branch count must have spent time
145#		waiting.
146#
147#	Find symbols by pattern matching on part of the name (e.g. names containing 'alloc'):
148#
149#		SELECT * FROM symbols_view WHERE name LIKE '%alloc%';
150#
151#	Top 10 function calls for a specific symbol (e.g. whose symbol_id is 187):
152#
153#		SELECT * FROM calls_view WHERE symbol_id = 187 ORDER BY elapsed_time DESC LIMIT 10;
154#
155#	Show function calls made by function in the same context (i.e. same call path) (e.g. one with call_path_id 254):
156#
157#		SELECT * FROM calls_view WHERE parent_call_path_id = 254;
158#
159#	Show branches made during a function call (e.g. where call_id is 29357 and return_id is 29370 and tid is 29670)
160#
161#		SELECT * FROM samples_view WHERE id >= 29357 AND id <= 29370 AND tid = 29670 AND event LIKE 'branches%';
162#
163#	Show transactions:
164#
165#		SELECT * FROM samples_view WHERE event = 'transactions';
166#
167#		Note transaction start has 'in_tx' true whereas, transaction end has 'in_tx' false.
168#		Transaction aborts have branch_type_name 'transaction abort'
169#
170#	Show transaction aborts:
171#
172#		SELECT * FROM samples_view WHERE event = 'transactions' AND branch_type_name = 'transaction abort';
173#
174# To print a call stack requires walking the call_paths table.  For example this python script:
175#   #!/usr/bin/python2
176#
177#   import sys
178#   from PySide.QtSql import *
