scripts/graph-build-time: properly warn about missing modules

2014-10-12T15:23:06+00:00

Currently the graph-build-time script prints a python exception if a needed module cannot be imported. Catch the exception and tell the user which packages are missing, as we do for other missing dependencies. Signed-off-by: Luca Ceresoli Signed-off-by: Peter Korsgaard

scripts/graph-build-time: clarify backend selection

2014-10-12T15:21:00+00:00

This instruction in the middle of 'import' lines looks very strange. Also, it was not obvious to me what the 'Agg' backend is. Both things are actually correct, but it took a while to find out why. So clarify with a comment to save someone else's time. [Peter: fix s/soe/some/ typo] Signed-off-by: Luca Ceresoli Cc: Sascha Arthur Cc: "Yann E.

support/graphs: fix comparisons agains None

2014-04-14T20:50:24+00:00

As Samuel said: In Python, None is a singleton, and it is recommended to use "is" or "is not" for testing them [1].

graphs: make graphs with lots of packages nicer to look at

2014-04-14T20:13:04+00:00

Some magic numbers obtained with trial-and-error and successive iterations, to eventually get a nice graph. [Thomas: remove excessive spaces in expressions.] Reported-by: Thomas Petazzoni Signed-off-by: "Yann E. MORIN" Signed-off-by: Thomas Petazzoni

graphs: support generating png graphs

2013-12-29T11:13:25+00:00

PDF files can not be easily embedded in other documents (eg. ODT, or HTML). Add support for generating PNG graphs, by setting the GRAPH_OUT=pdf|png on the command line: make GRAPH_OUT=png graph-build graph-depends The default is still to generate PDF graphs.

graph-build-time: generate graphs based on timing data

2013-12-29T11:12:38+00:00

This script generates graphs of packages build time, from the timing data generated by Buildroot in the $(O)/build-time.log file. Example usage: ./support/scripts/graph-build-time \ --type=histogram --input=$(O)/build-time.log --output=foobar.pdf Three graph types are available : * histogram, which creates an histogram of the build time for each package, decomposed by each step (extract, patch, configure, etc.). The order in which the packages are shown is configurable: by package name, by build order, or by duration order. See the --order option. * pie-packages, which creates a pie chart of the build time of each package (without decomposition in steps). Packages that contributed to less than 1% of the overall build time are all grouped together in an "Other" entry. * pie-steps, which creates a pie chart of the time spent globally on each step (extract, patch, configure, etc...) The default is to generate an histogram ordered by package name. Signed-off-by: Thomas Petazzoni [yann.morin.1998@free.fr: adapt to the format of the step-hooks build-time.log, add sort order by name, default to name-ordered histogram, use our colours for pie-charts, add alternate color-scheme, add short-options, add --input/-i] Signed-off-by: "Yann E.
