2017-01-28scripts/buildstats-diff: simplify timestamp handlingMarkus Lehtonen
Simply use floats instead of datetime and timedelta objects for handling timestamps. (From OE-Core rev: d97c844f388bd4c52248fe597d5985ef20d5a96d) Signed-off-by: Markus Lehtonen <markus.lehtonen@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2016-10-01scripts/buildstats-diff: implement --multi optionMarkus Lehtonen
Makes it possible to average over multiple buildstats. If --multi is specified (and the given path is a directory) the script will read all buildstats from the given directory and use averaged values calculated from them. All of the buildstats must be from a "similar" build, meaning that no differences in package versions or tasks are allowed. Otherwise, the script will exit with an error.

2016-10-01scripts/buildstats-diff: use exception for internal error handlingMarkus Lehtonen

2016-10-01scripts/buildstats-diff: add walltime to --diff-attrMarkus Lehtonen
For comparing the elapsed wall clock time of tests. Default values for --min-val and --min-absdiff are 5 seconds and 2 seconds.

2016-10-01scripts/buildstats-diff: add read_ops and write_ops to --diff-attrMarkus Lehtonen
Two new options, making it possible to compare the number of filesystem operations of tasks. Defaults for --min-val and --min-absdiff are set to more or less arbitrary 500 and 50 operations, respectively.

2016-10-01scripts/buildstats-diff: add read_bytes and write_bytes to --diff-attrMarkus Lehtonen
These are I/O counter values from /proc/<pid>/io and represent the number of bytes read from / written to the storage layer. Default values for --min-val and --min-absdiff limits are set to 512kB and 128kB, respectively.

2016-10-01scripts/buildstats-diff: introduce --diff-attrMarkus Lehtonen
A new command line option for choosing which "attribute" of the buildstats to compare. At first, the already supported 'cputime' is the only available option. But, refactoring done in this patch should make it easy to add new attribute types.

2016-10-01scripts/buildstats-diff: do not hardcode field widths in outputMarkus Lehtonen
Dynamically adjust the width of all fields in task diff output. Makes it easier to print other units than cputime, too.

2016-10-01scripts/buildstats-diff: implement BSTask classMarkus Lehtonen
New class representing buildstats data of a single task.

2016-10-01scripts/buildstats-diff: rename --min-time and --min-timediff argsMarkus Lehtonen
Rename these arguments to --min-val and --min-absdiff in preparation for supporting other "quantities" than just cputime.

2016-09-16scripts: introduce buildstats-diffMarkus Lehtonen
New script for comparing buildstats from two separate builds. The script has two modes: normally it prints the differences in task execution (cpu) times but using --ver-diff option makes it just print the recipe version differences without any cpu time data. Other command line options are provided to alter the sort criteria of the data and to filter out insignificant differences and/or short tasks.
