Some commands chain grep and sed while sed already does grep by
default, let's simply use sed. In addition to being more intuitive,
it saves up to 150ms per run on the 13 tests covered by level 4.
Use #!bin/sh more portable shebang.
Support filenames with spaces.
Set HAPROXY_PROGRAM environment variable value to ${PWD}/haproxy.
exit(1) if we could not creat the higher level temporary working directory
or create its sub-directory with mktemp utility.
As defined by POSIX, use six characters for the mktemp template.
Some tests require a minimal haproxy version or compilation options to be
able to run successfully. This script allows to add 'requirements' to tests
to check so they will automatically be skipped if a requirement is not met.
The script supports several parameters to slightly modify its behavior
including the directories to search for tests.
Also some features are not available for certain OS's these can also
be 'excluded', this should allow for the complete set of test cases to be
run on any OS against any haproxy release without 'expected failures'.
The test .vtc files will need to be modified to include their 'requirements'
by listing including text options as shown below:
#EXCLUDE_TARGETS=dos,freebsd,windows
#REQUIRE_OPTIONS=ZLIB,OPENSSL,LUA
#REQUIRE_VERSION=0.0
#REQUIRE_VERSION_BELOW=99.9,
When excluding a OS by its TARGET, please do make a comment why the test
can not succeed on that TARGET.
