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 python-pyside.qtsql libqt4-sql-psql
38#	$ sudo su - postgres
39#	$ createuser -s <your user id here>
40#
41# An example of using this script with Intel PT:
42#
43#	$ perf record -e intel_pt//u ls
44#	$ perf script -s ~/libexec/perf-core/scripts/python/export-to-postgresql.py pt_example branches calls

51#	2015-05-29 12:49:29.365350 Done
52#
53# To browse the database, psql can be used e.g.
54#
55#	$ psql pt_example
56#	pt_example=# select * from samples_view where id < 100;
57#	pt_example=# \d+
58#	pt_example=# \d+ samples_view
59#	pt_example=# \q
60#
61# An example of using the database is provided by the script
62# call-graph-from-postgresql.py.  Refer to that script for details.
63#
64# Tables:
65#
66#	The tables largely correspond to perf tools' data structures.  They are largely self-explanatory.
67#
68#	samples
69#
70#		'samples' is the main table. It represents what instruction was executing at a point in time
71#		when something (a selected event) happened.  The memory address is the instruction pointer or 'ip'.
72#
73#	calls
74#
75#		'calls' represents function calls and is related to 'samples' by 'call_id' and 'return_id'.
76#		'calls' is only created when the 'calls' option to this script is specified.
77#
78#	call_paths
79#
80#		'call_paths' represents all the call stacks.  Each 'call' has an associated record in 'call_paths'.
81#		'calls_paths' is only created when the 'calls' option to this script is specified.
82#
83#	branch_types
84#
85#		'branch_types' provides descriptions for each type of branch.
86#
87#	comm_threads
88#
89#		'comm_threads' shows how 'comms' relates to 'threads'.
90#
91#	comms
92#
93#		'comms' contains a record for each 'comm' - the name given to the executable that is running.
94#
95#	dsos
96#
97#		'dsos' contains a record for each executable file or library.
98#
99#	machines
100#
101#		'machines' can be used to distinguish virtual machines if virtualization is supported.
102#
103#	selected_events
104#
105#		'selected_events' contains a record for each kind of event that has been sampled.
106#
107#	symbols
108#
109#		'symbols' contains a record for each symbol.  Only symbols that have samples are present.
110#
111#	threads
112#
113#		'threads' contains a record for each thread.
114#
115# Views:
116#
117#	Most of the tables have views for more friendly display.  The views are:
118#
119#		calls_view
120#		call_paths_view
121#		comm_threads_view
122#		dsos_view
123#		machines_view
124#		samples_view
125#		symbols_view
126#		threads_view
127#
128# More examples of browsing the database with psql:
129#   Note that some of the examples are not the most optimal SQL query.
130#   Note that call information is only available if the script's 'calls' option has been used.
131#
132#	Top 10 function calls (not aggregated by symbol):
133#
134#		SELECT * FROM calls_view ORDER BY elapsed_time DESC LIMIT 10;
135#
136#	Top 10 function calls (aggregated by symbol):
137#
138#		SELECT symbol_id,(SELECT name FROM symbols WHERE id = symbol_id) AS symbol,
139#			SUM(elapsed_time) AS tot_elapsed_time,SUM(branch_count) AS tot_branch_count
140#			FROM calls_view GROUP BY symbol_id ORDER BY tot_elapsed_time DESC LIMIT 10;
141#
142#		Note that the branch count gives a rough estimation of cpu usage, so functions
143#		that took a long time but have a relatively low branch count must have spent time
144#		waiting.
145#
146#	Find symbols by pattern matching on part of the name (e.g. names containing 'alloc'):
147#
148#		SELECT * FROM symbols_view WHERE name LIKE '%alloc%';
149#
150#	Top 10 function calls for a specific symbol (e.g. whose symbol_id is 187):
151#
152#		SELECT * FROM calls_view WHERE symbol_id = 187 ORDER BY elapsed_time DESC LIMIT 10;
153#
154#	Show function calls made by function in the same context (i.e. same call path) (e.g. one with call_path_id 254):
155#
156#		SELECT * FROM calls_view WHERE parent_call_path_id = 254;
157#
158#	Show branches made during a function call (e.g. where call_id is 29357 and return_id is 29370 and tid is 29670)
159#
160#		SELECT * FROM samples_view WHERE id >= 29357 AND id <= 29370 AND tid = 29670 AND event LIKE 'branches%';
161#
162#	Show transactions:
163#
164#		SELECT * FROM samples_view WHERE event = 'transactions';
165#
166#		Note transaction start has 'in_tx' true whereas, transaction end has 'in_tx' false.
167#		Transaction aborts have branch_type_name 'transaction abort'
168#
169#	Show transaction aborts:
170#
171#		SELECT * FROM samples_view WHERE event = 'transactions' AND branch_type_name = 'transaction abort';
172#
173# To print a call stack requires walking the call_paths table.  For example this python script:
174#   #!/usr/bin/python2
175#
176#   import sys
177#   from PySide.QtSql import *
