| # This script plots the categories of tests by group. It does this by combining |
| # the awk script and gnuplot script of the same name. This script accepts an |
| # argument, in the format of a grep expression, that allows the tests to be |
| # filtered before categorization. This script produces the plot as a png on |
| # stdout. |
| |
| # Variables |
| # ========= |
| |
| # I would like to use process-substitution for this, so that we can avoid |
| # making a file on disk and keep everything in memory, removing the need to |
| # clean anything up on exit and preventing any chance of polluting the user's |
| # filesystem. However, when gnuplot is asked to plot from the same file more |
| # than once, it will seek to the start of the file for every subsequent plot |
| # after the first. Unix Pipes do not support this operation, and plotting fails |
| # under these circumstances. Instead, we use an intermediate file, which is |
| # removed on success. |
| categories=$(mktemp "XXXXXXX-test-categories.dat") |
| |
| # We change a portion of the title for our graph based on the argument passed to |
| # this script. |
| subtitle=$([[ $# -ge 1 ]] && echo " (Filter: \"$1\")" || true) |
| |
| # Generate Data into the ${categories} file |
| # ========================================= |
| # |
| # The following pipeline is the heart of the implementation, and has four |
| # stages: find, ???, awk, and sort. The ??? stage of the pipeline is determined |
| # by the bash if statement, which switches between a filter, when an argument |
| # is passed, and a passthrough, implemented as `cat -`, when no filter argument |
| # is passed. |
