10 years leaves its mark! Python has evolved and so has its style guide.
Even with vim it is getting hard to follow the no longer valid
guidelines (spaces vs. tabs).
Autopep8 this code to modernize it!

This script works in tandem with d3-flame-graph to generate flame graphs
from perf. It supports two output formats: JSON and HTML (the default).
The HTML format will look for a standalone d3-flame-graph template file
in /usr/share/d3-flame-graph/d3-flamegraph-base.html and fill in the
collected stacks.
Usage:
perf record -a -g -F 99 sleep 60
perf script report flamegraph
Combined:
perf script flamegraph -a -F 99 sleep 60
Committer testing:
Tested both with "PYTHON=python3" and with the default, that uses
python2-devel:
Complete set of instructions:
$ mkdir /tmp/build/perf
$ make PYTHON=python3 -C tools/perf O=/tmp/build/perf install-bin
$ export PATH=~/bin:$PATH
$ perf record -a -g -F 99 sleep 60
$ perf script report flamegraph
Now go and open the generated flamegraph.html file in a browser.
At first this required building with PYTHON=python3, but after I
reported this Andreas was kind enough to send a patch making it work
with both python and python3.

The user probably wants to replace the find text, so select the find
text when the find bar is activated.
That is fairly standard behaviour for search text entry.
Entering text will replace the current text, but using edit keys
(arrows, home, end etc) cancels the selection and enables editing.

cset don't make it to break and if the changes in the db schema are the
ones expected:
[root@quaco adrian.hunter]# perf script -i simple-retpoline.perf.data --itrace=be -s ~acme/libexec/perf-core/scripts/python/export-to-sqlite.py simple-retpoline.db branches calls

[root@quaco adrian.hunter]#
Now lets use the db:
[root@quaco adrian.hunter]# sqlite3 simple-retpoline.db
SQLite version 3.26.0 2018-12-01 12:34:55
Enter ".help" for usage hints.
sqlite> .schema samples
CREATE TABLE samples (id integer NOT NULL PRIMARY KEY,evsel_id bigint,machine_id bigint,thread_id bigint,comm_id bigint,dso_id bigint,symbol_id bigint,sym_offset bigint,ip bigint,time bigint,cpuinteger,to_dso_id bigint,to_symbol_id bigint,to_sym_offset bigint,to_ip bigint,branch_type integer,in_tx boolean,call_path_id bigint,insn_count bigint,cyc_count bigint);
sqlite>
Cool, the 'insn_count' and 'cyc_count' are there, now lets see if we can
use them in a query:
sqlite> select insn_count,cyc_count from samples where cyc_count > 1500 and insn_count < 10;
6|1507
sqlite> select insn_count,cyc_count from samples where cyc_count > 1500;
118|2210
140|1516
3783|1861
132|1521
6|1507
sqlite>
Seems to work :-)

pyside2 is the future for pyside support.
Note pyside use Qt4 whereas pyside2 uses Qt5.
Committer testing:
On a system with just:
# rpm -qa| grep -i pyside
python2-pyside-1.2.4-7.fc29.x86_64
#
Running:
$ python ~acme/libexec/perf-core/scripts/python/exported-sql-viewer.py ~/c/adrian.hunter/simple-retpoline.db &
[1] 7438
Makes it use the pyside 1 files:
$ grep -i pyside /proc/7438/maps | cut -d ' ' -f 6- | sort -u
/usr/lib64/libpyside-python2.7.so.1.2.4
/usr/lib64/python2.7/site-packages/PySide/QtCore.so
/usr/lib64/python2.7/site-packages/PySide/QtGui.so
/usr/lib64/python2.7/site-packages/PySide/QtSql.so
$ rpm -qf /usr/lib64/libpyside-python2.7.so.1.2.4
python2-pyside-1.2.4-7.fc29.x86_64
$
To get PySide2 I guess one needs to do:
$ pip install PySide2
But thats a 142MiB download I can't do right now, perhaps before pushing
upstream...

With support for Python 2 or 3 and PySide 1 or 2 (Qt 4 or 5), it is
useful to see what versions are in use. Add an 'About' dialog box that
displays Python, PySide, Qt and database server (SQLite or PostgreSQL)
version numbers.
Committer testing:
$ python ~acme/libexec/perf-core/scripts/python/exported-sql-viewer.py ~/c/adrian.hunter/simple-retpoline.db
Then go to 'Help', then 'About', select all the lines with the mouse
press 'Control+C', then, on the same terminal press control+shift+V
which shows my current environment:
Python version: 2.7.16
PySide version: 1
Qt version: 4.8.7
SQLite version: 3.26.0

Add a context menu (right-click) that provides options for copying to
clipboard, including, for trees, the ability to copy only the cell under
the mouse pointer.
Committer testing:
$ python ~acme/libexec/perf-core/scripts/python/exported-sql-viewer.py ~/c/adrian.hunter/simple-retpoline.db
Simply right click and pick "Copy selection", that at this point has
just the first line, not expanded, then see what was copied by pressing
shift+control+v on a terminal:
Call Path,Object,Count,Time (ns),Time (%),Branch Count,Branch Count (%)
▶ simple-retpolin,,,,,,
Ditto after expanding, i.e. the selection continues to be just one
line:
Call Path Object Count Time (ns) Time (%) Branch Count Branch Count (%)
▼ simple-retpolin
Now select all the lines with the mouse and control+shift+v again:
Call Path Object Count Time (ns) Time (%) Branch Count Branch Count (%)
▼ 14503:14503
▼ _start ld-2.28.so 1 156267 100.0 10602 100.0

Fix the following error if shrink / enlarge font is used with the help
window.
Traceback (most recent call last):
File "tools/perf/scripts/python/exported-sql-viewer.py", line 2791, in ShrinkFont
ShrinkFont(win.view)
AttributeError: 'HelpWindow' object has no attribute 'view'
Committer testing:
Before, matches above output:
$ python ~acme/libexec/perf-core/scripts/python/exported-sql-viewer.py ~/c/adrian.hunter/simple-retpoline.db
Traceback (most recent call last):
File "/home/acme/libexec/perf-core/scripts/python/exported-sql-viewer.py", line 2780, in EnlargeFont
EnlargeFont(win.view)
AttributeError: 'HelpWindow' object has no attribute 'view'
$
After:
No more tracebacks, but the fonts don't get enlarged, which is kinda
frustrating...
