| | | | | | | | | | | If the difference between the old and new instruction count and/or memory usage is higher than a (user-configurable) threshold, do not remove the temporary directory and direct the user to its location. This way, they can investigate the regression right away, rather than having to re-run valgrind etc. Change-Id: I8a35fde073806fa9daf0b28315a827207f8bd04d Reviewed-by: Jake Petroules <jake.petroules@qt.io>

* Change style of #includes of Qt headersJake Petroules2017-01-0411-28/+31
| | | | | | | | | | | | | | | | By using q<lowercase>.h headers, we become more bootstrap-friendly, as no full syncqt is required any more. In the same go, prefix all includes with the module name. This helps grep-based analysis of which parts of Qt are used and where. It's also consistent with Qt's public headers (where syncqt enforces the style). Testdata and examples are excluded from the change, as they are not relevant for bootstrapping.

* Fix restoration of symbolic commitsJoerg Bornemann2017-01-023-3/+17
| | | | | | | | | | | | | | | | qbs-benchmarker tries to restore the original commit of the qbs repository. To determine that commit the command git describe HEAD is used. For the 1.7 branch this produces something like v1.7.0-26-g2bc9373 which then is passed to 'git checkout'. Afterwards the repo is in detached HEAD state. Use 'git symbolic-ref' to determine the correct original branch name. Fall back to the old method if that doesn't work.

* Add benchmarking tool.Christian Kandeler2015-02-1713-0/+1083
Takes two qbs repo states, runs callgrind and massif on different phases of the build process for each of them and informs the user of the relative performance of these operations. I suggest running this tool before committing anything that could conceivably impact performance. Note that we have similar regression detection functionality on our build machines, but it's better to spot such problems before pushing a change. Example output (for commits 04df1532c4 and f53d724eec building qbs itself): ========== Performance data for Resolving ========== Old instruction count: 1931242543 New instruction count: 1457438375 Relative change: -25 % Old peak memory usage: 1710721 Bytes New peak memory usage: 1509879 Bytes Relative change: -12 % ========== Performance data for Rule Execution ========== Old instruction count: 2924308821 New instruction count: 2890322188 Relative change: -2 % Old peak memory usage: 2520740 Bytes New peak memory usage: 2488058 Bytes Relative change: -2 % ========== Performance data for Null Build ========== Old instruction count: 572213104 New instruction count: 517813513 Relative change: -10 % Old peak memory usage: 1964455 Bytes New peak memory usage: 1774279 Bytes Relative change: -10 % Change-Id: I1f05c647d204b6cacf3539c8ecbf13633b757cf7 Reviewed-by: Joerg Bornemann <joerg.bornemann@theqtcompany.com>
