Version Test - Simple program to run through a file and comare versions.
|
|
|
|
Each version is compared and the result is checked against an expected
|
|
result in the file. The format of the file is
|
|
a b Res
|
|
Where Res is -1, 1, 0. dpkg -D=1 --compare-versions a "<" b can be
|
|
used to determine what Res should be. # at the start of the line
|
|
is a comment and blank lines are skipped
|
|
|
|
The runner will also call dpkg --compare-versions to check if APT and
|
|
dpkg have (still) the same idea.
