debhelper versions – Guilty!

After reading Jakub’s pet peeve about debhelper build-dependencies I decided to check my own and sponsored packages to see how they fare.

find debian/ -type f -name control | xargs grep -h -o 'debhelper (>= 9[^)]*)' | sort | uniq -c
      2 debhelper (>= 9)
      2 debhelper (>= 9.0)
      3 debhelper (>= 9.0.0)
      1 debhelper (>= 9.20120115)

Oops! Something to fix in all subsequent releases.

Dejagnu tips

Both the procps and psmisc projects use Dejagnu for their testing.  It’s interesting to try to understand how it all works and learning a new language TCL.  One of the big problems with Dejagnu is its documentation which is very sparse. So here are two things I’ve picked up along the way for a reference for myself and others.


We recently had a bug report on the procps list where tests for w failed for someone when the headers were shown.  After a some further debugging it was a locale problem, where the testsuite was looking for a number like 3.14 but the tester was seeing 3,14. There are many ways around this but for us it was to set the locale, with the following line in config/unix.exp after suggestions by Mike Frysinger should fix it.

set env(LC_ALL) "C"

Cleaning Up
The documentation on this function is awesome! A title “Cleanup Procedure” and one line “cleanup()”.
That’s all you get. The cleanup proc or function is called at the end of the testing. I use it
to remove temporary files and things like that.

proc cleanup { } {
        global test_file
        exec rm $test_file
