* perf scripts python: call-graph-from-sql.py: Rename to exported-sql-viewer.pyAdrian Hunter2018-10-231-395/+0
| | | | | | | | | | | Additional reports will be added to the script so rename to reflect the more general purpose.

* perf scripts python: call-graph-from-sql.py: Refactor TreeItem classAdrian Hunter2018-10-231-140/+133
| | | | | | | | | | | | | | class TreeItem represents items at all levels of the call-graph tree. However, not all the levels represent the same data i.e. the top-level is comms, the next level is threads, and subsequent levels are functions. Consequently it is simpler to have separate classes for different levels with commonality in a base class. Refactor TreeItem class accordingly.

| | | | | | | | | | | | | | | | | There are not many standard icons, but the computer icon looks slightly better than the information icon.

* perf script python: Add support for sqlite3 to call-graph-from-sql.pyAdrian Hunter2017-08-151-24/+36
| | | | | | | | | | | | | | | | | | Add support for SQLite 3 to the call-graph-from-sql.py script. The SQL statements work as is, so just detect the database type by checking if the SQLite 3 file exists. Committer notes: Tested collecting the PT data on a RHEL7.4, generating the SQLite3 database there and then moving it to a Fedora 26 system where the call-graph-from-sql.py script was run, using python-pyside version 1.2.2-7fc26 to see the callgraphs using Qt4.
