As part of the ongoing efforts to improve Automake integration, I have
split the previously-conflated uses of $srcdir in DejaGnu. Due to the
current architecture of DejaGnu, the new variable created to hold the
base directory of the testsuite ("@srcdir@/testsuite" using Automake's
@srcdir@) is visible to test scripts.
At the moment that variable is named "testsuitedir" and may or may not
have the same value as "srcdir". The core uses it, but it could also be
useful as a transitional feature in test scripts, since a script using
this variable will work independently of using Automake's srcdir value
or a legacy srcdir=@srcdir@/testsuite value.
Is "testsuitedir" the best name for this variable or can anyone suggest
a better name, or possibly an API call to wrap it? (Maybe something
like "[testsuite file <name>...]" to refer to a file within the
testsuite sources, equivalent to "[file join $testsuitedir <name>...]"?)
Interestingly, the DejaGnu procedure "getdirs" excludes directories
named "testsuite" from recursive searches. An alternative would be for
this procedure to instead enter "testsuite" as its first step, but
keeping the current behavior allows nested testsuites that use runtest
recursively without having the outer runtest scan inner testsuites.
This will be useful for the DejaGnu testsuite itself at a minimum.
