20# To use this script you will need to have installed package python-pyside which
21# provides LGPL-licensed Python bindings for Qt.  You will also need the package
22# libqt4-sql-psql for Qt postgresql support.
23#
24# The script assumes postgresql is running on the local machine and that the
25# user has postgresql permissions to create databases. Examples of installing
26# postgresql and adding such a user are:
27#
28# fedora:
29#
30#	$ sudo yum install postgresql postgresql-server qt-postgresql
31#	$ sudo su - postgres -c initdb
32#	$ sudo service postgresql start
33#	$ sudo su - postgres
34#	$ createuser -s <your user id here>    # Older versions may not support -s, in which case answer the prompt below:
35#	Shall the new role be a superuser? (y/n) y
36#	$ sudo yum install python-pyside
37#
38#	Alternately, to use Python3 and/or pyside 2, one of the following:
39#		$ sudo yum install python3-pyside
40#		$ pip install --user PySide2
41#		$ pip3 install --user PySide2
42#
43# ubuntu:
44#
45#	$ sudo apt-get install postgresql
46#	$ sudo su - postgres
47#	$ createuser -s <your user id here>
48#	$ sudo apt-get install python-pyside.qtsql libqt4-sql-psql
49#
50#	Alternately, to use Python3 and/or pyside 2, one of the following:
51#
52#		$ sudo apt-get install python3-pyside.qtsql libqt4-sql-psql
53#		$ sudo apt-get install python-pyside2.qtsql libqt5sql5-psql
54#		$ sudo apt-get install python3-pyside2.qtsql libqt5sql5-psql
55#
56# An example of using this script with Intel PT:
57#
58#	$ perf record -e intel_pt//u ls
59#	$ perf script -s ~/libexec/perf-core/scripts/python/export-to-postgresql.py pt_example branches calls

66#	2015-05-29 12:49:29.365350 Done
67#
68# To browse the database, psql can be used e.g.
69#
70#	$ psql pt_example
71#	pt_example=# select * from samples_view where id < 100;
72#	pt_example=# \d+
73#	pt_example=# \d+ samples_view
74#	pt_example=# \q
75#
76# An example of using the database is provided by the script
77# exported-sql-viewer.py.  Refer to that script for details.
78#
79# Tables:
80#
81#	The tables largely correspond to perf tools' data structures.  They are largely self-explanatory.
82#
83#	samples
84#
85#		'samples' is the main table. It represents what instruction was executing at a point in time
86#		when something (a selected event) happened.  The memory address is the instruction pointer or 'ip'.
87#
88#	calls
89#
90#		'calls' represents function calls and is related to 'samples' by 'call_id' and 'return_id'.
91#		'calls' is only created when the 'calls' option to this script is specified.
92#
93#	call_paths
94#
95#		'call_paths' represents all the call stacks.  Each 'call' has an associated record in 'call_paths'.
96#		'calls_paths' is only created when the 'calls' option to this script is specified.
97#
98#	branch_types
99#
100#		'branch_types' provides descriptions for each type of branch.
101#
102#	comm_threads
103#
104#		'comm_threads' shows how 'comms' relates to 'threads'.
105#
106#	comms
107#
108#		'comms' contains a record for each 'comm' - the name given to the executable that is running.
109#
110#	dsos
111#
112#		'dsos' contains a record for each executable file or library.
113#
114#	machines
115#
116#		'machines' can be used to distinguish virtual machines if virtualization is supported.
117#
118#	selected_events
119#
120#		'selected_events' contains a record for each kind of event that has been sampled.
121#
122#	symbols
123#
124#		'symbols' contains a record for each symbol.  Only symbols that have samples are present.
125#
126#	threads
127#
128#		'threads' contains a record for each thread.
129#
130# Views:
131#
132#	Most of the tables have views for more friendly display.  The views are:
133#
134#		calls_view
135#		call_paths_view
136#		comm_threads_view
137#		dsos_view
138#		machines_view
139#		samples_view
140#		symbols_view
141#		threads_view
142#
143# More examples of browsing the database with psql:
144#   Note that some of the examples are not the most optimal SQL query.
145#   Note that call information is only available if the script's 'calls' option has been used.
146#
147#	Top 10 function calls (not aggregated by symbol):
148#
149#		SELECT * FROM calls_view ORDER BY elapsed_time DESC LIMIT 10;
150#
151#	Top 10 function calls (aggregated by symbol):
152#
153#		SELECT symbol_id,(SELECT name FROM symbols WHERE id = symbol_id) AS symbol,
154#			SUM(elapsed_time) AS tot_elapsed_time,SUM(branch_count) AS tot_branch_count
155#			FROM calls_view GROUP BY symbol_id ORDER BY tot_elapsed_time DESC LIMIT 10;
156#
157#		Note that the branch count gives a rough estimation of cpu usage, so functions
158#		that took a long time but have a relatively low branch count must have spent time
159#		waiting.
160#
161#	Find symbols by pattern matching on part of the name (e.g. names containing 'alloc'):
162#
163#		SELECT * FROM symbols_view WHERE name LIKE '%alloc%';
164#
165#	Top 10 function calls for a specific symbol (e.g. whose symbol_id is 187):
166#
167#		SELECT * FROM calls_view WHERE symbol_id = 187 ORDER BY elapsed_time DESC LIMIT 10;
168#
169#	Show function calls made by function in the same context (i.e. same call path) (e.g. one with call_path_id 254):
170#
171#		SELECT * FROM calls_view WHERE parent_call_path_id = 254;
172#
173#	Show branches made during a function call (e.g. where call_id is 29357 and return_id is 29370 and tid is 29670)
174#
175#		SELECT * FROM samples_view WHERE id >= 29357 AND id <= 29370 AND tid = 29670 AND event LIKE 'branches%';
176#
177#	Show transactions:
178#
179#		SELECT * FROM samples_view WHERE event = 'transactions';
180#
181#		Note transaction start has 'in_tx' true whereas, transaction end has 'in_tx' false.
182#		Transaction aborts have branch_type_name 'transaction abort'
183#
184#	Show transaction aborts:
185#
186#		SELECT * FROM samples_view WHERE event = 'transactions' AND branch_type_name = 'transaction abort';
187#
188# To print a call stack requires walking the call_paths table.  For example this python script:
189#   #!/usr/bin/python2
190#
191#   import sys
192#   from PySide.QtSql import *
