# provides LGPL-licensed Python bindings for Qt. You will also need the package
|
|
# libqt4-sql-sqlite for Qt sqlite3 support.
|
|
#
|
|
# An example of using this script with Intel PT:
|
|
#
|
|
# $ perf record -e intel_pt//u ls
|
|
# $ perf script -s ~/libexec/perf-core/scripts/python/export-to-sqlite.py pt_example branches calls

|
|
# To browse the database, sqlite3 can be used e.g.
|
|
#
|
|
# $ sqlite3 pt_example
|
|
# sqlite> .header on
|
|
# sqlite> select * from samples_view where id < 10;
|
|
# sqlite> .mode column
|
|
# sqlite> select * from samples_view where id < 10;
|
|
# sqlite> .tables
|
|
# sqlite> .schema samples_view
|
|
# sqlite> .quit
|
|
#
|
|
# An example of using the database is provided by the script
|
|
# call-graph-from-sql.py. Refer to that script for details.
|
|
#
|
|
# The database structure is practically the same as created by the script
|
|
# export-to-postgresql.py. Refer to that script for details. A notable
|
|
# difference is the 'transaction' column of the 'samples' table which is
|
|
# renamed 'transaction_' in sqlite because 'transaction' is a reserved word.
