# exported-sql-viewer.py: view data from sql database
# Copyright (c) 2014-2018, Intel Corporation.
# To use this script you will need to have exported data using either the
# export-to-sqlite.py or the export-to-postgresql.py script. Refer to those
# scripts for details.
#
# Following on from the example in the export scripts, a
# call-graph can be displayed for the pt_example database like this:
#
# python tools/perf/scripts/python/exported-sql-viewer.py pt_example
#
# Note that for PostgreSQL, this script supports connecting to remote databases
# by setting hostname, port, username, password, and dbname e.g.
#
# python tools/perf/scripts/python/exported-sql-viewer.py "hostname=myhost username=myuser password=mypassword dbname=pt_example"
#
# The result is a GUI window with a tree representing a context-sensitive
# call-graph. Expanding a couple of levels of the tree and adjusting column
# widths to suit will display something like:
#
# Call Graph: pt_example
# Call Path Object Count Time(ns) Time(%) Branch Count Branch Count(%)
# v- ls
# v- 2638:2638

#
# Points to note:
# The top level is a command name (comm)
# The next level is a thread (pid:tid)
# Subsequent levels are functions
# 'Count' is the number of calls
# 'Time' is the elapsed time until the function returns
# Percentages are relative to the level above
# 'Branch Count' is the total number of branches for that function and all
# functions that it calls
# There is also a "All branches" report, which displays branches and
# possibly disassembly. However, presently, the only supported disassembler is
# Intel XED, and additionally the object code must be present in perf build ID
# cache. To use Intel XED, libxed.so must be present. To build and install
# libxed.so:
# git clone https://github.com/intelxed/mbuild.git mbuild
# git clone https://github.com/intelxed/xed
# cd xed
# ./mfile.py --share
# sudo ./mfile.py --prefix=/usr/local install
# sudo ldconfig

<h3>Points to note:</h3>
<ul>
<li>The top level is a command name (comm)</li>
<li>The next level is a thread (pid:tid)</li>
<li>Subsequent levels are functions</li>
<li>'Count' is the number of calls</li>
<li>'Time' is the elapsed time until the function returns</li>
<li>Percentages are relative to the level above</li>
<li>'Branch Count' is the total number of branches for that function and all functions that it calls
</ul>
<h3>Find</h3>
Ctrl-F displays a Find bar which finds function names by either an exact match or a pattern match.
The pattern matching symbols are ? for any character and * for zero or more characters.
<h2 id=calltree>1.2 Call Tree</h2>
The Call Tree report is very similar to the Context-Sensitive Call Graph, but the data is not aggregated.
Also the 'Count' column, which would be always 1, is replaced by the 'Call Time'.
<h2 id=allbranches>1.3 All branches</h2>
The All branches report displays all branches in chronological order.
Not all data is fetched immediately. More records can be fetched using the Fetch bar provided.
<h3>Disassembly</h3>
Open a branch to display disassembly. This only works if:
<ol>
<li>The disassembler is available. Currently, only Intel XED is supported - see <a href=#xed>Intel XED Setup</a></li>
<li>The object code is available. Currently, only the perf build ID cache is searched for object code.
The default directory ~/.debug can be overridden by setting environment variable PERF_BUILDID_DIR.
One exception is kcore where the DSO long name is used (refer dsos_view on the Tables menu),
or alternatively, set environment variable PERF_KCORE to the kcore file name.</li>
</ol>
<h4 id=xed>Intel XED Setup</h4>
To use Intel XED, libxed.so must be present. To build and install libxed.so:
<pre>
git clone https://github.com/intelxed/mbuild.git mbuild
git clone https://github.com/intelxed/xed
cd xed
./mfile.py --share
sudo ./mfile.py --prefix=/usr/local install
sudo ldconfig
</pre>
<h3>Find</h3>
Ctrl-F displays a Find bar which finds substrings by either an exact match or a regular expression match.
Refer to Python documentation for the regular expression syntax.
All columns are searched, but only currently fetched rows are searched.
<h2 id=selectedbranches>1.4 Selected branches</h2>
This is the same as the <a href=#allbranches>All branches</a> report but with the data reduced
by various selection criteria. A dialog box displays available criteria which are AND'ed together.
<h3>1.4.1 Time ranges</h3>
The time ranges hint text shows the total time range. Relative time ranges can also be entered in
ms, us or ns. Also, negative values are relative to the end of trace. Examples:
<pre>
81073085947329-81073085958238 From 81073085947329 to 81073085958238
100us-200us From 100us to 200us
10ms- From 10ms to the end
-100ns The first 100ns
-10ms- The last 10ms
</pre>
N.B. Due to the granularity of timestamps, there could be no branches in any given time range.
<h2 id=topcallsbyelapsedtime>1.5 Top calls by elapsed time</h2>
The Top calls by elapsed time report displays calls in descending order of time elapsed between when the function was called and when it returned.
The data is reduced by various selection criteria. A dialog box displays available criteria which are AND'ed together.
If not all data is fetched, a Fetch bar is provided. Ctrl-F displays a Find bar.
<h1 id=tables>2. Tables</h1>
The Tables menu shows all tables and views in the database. Most tables have an associated view
which displays the information in a more friendly way. Not all data for large tables is fetched
immediately. More records can be fetched using the Fetch bar provided. Columns can be sorted,
but that can be slow for large tables.
<p>There are also tables of database meta-information.
For SQLite3 databases, the sqlite_master table is included.
For PostgreSQL databases, information_schema.tables/views/columns are included.
<h3>Find</h3>
Ctrl-F displays a Find bar which finds substrings by either an exact match or a regular expression match.
Refer to Python documentation for the regular expression syntax.
All columns are searched, but only currently fetched rows are searched.
<p>N.B. Results are found in id order, so if the table is re-ordered, find-next and find-previous
will go to the next/previous result in id order, instead of display order.
