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-sql.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 *
