Yes, the problem is with Test-Harness-3.17. If I install that into 5.10.0,
@INC is broken in precisely the same way as on 5.10.1:
####################################
C:\>perl -MTest::Harness -e "runtests('inc.pl')"
inc.pl ..
INC: C:/PERL51~1/510~1.0/lib
INC: .
inc.pl .. ok
All tests successful.
Files=1, Tests=1, 0 wallclock secs ( 0.08 usr + 0.01 sys = 0.09 CPU)
Result: PASS
####################################
The original version of Test::Harness that I have for perl-5.10.0 is 2.64,
and it causes no such problem:
####################################
C:\>perl -MTest::Harness -e "runtests('inc.pl')"
inc....
INC: C:/perl510_M/5.10.0/lib
INC: C:/perl510_M/site/5.10.0/lib
INC: .
INC: C:/perl510_M/5.10.0/lib
INC: C:/perl510_M/site/5.10.0/lib
INC: .
inc....ok
All tests successful.
Files=1, Tests=1, 0 wallclock secs ( 0.00 cusr + 0.00 csys = 0.00 CPU)
####################################
It does "double up" on @INC, but that's not a problem.
(I've now switched from my XP box to my Vista box - and the keen observer
will note that @INC has changed slightly from my first post. Namely,
'C:/perl510_M/site/lib' is no longer in @INC. I'm not sure what accounts for
that difference, but that's not an issue for me - the main thing is to work
out how Test::Harness-3.17 is breaking @INC.)
Version 2.99_01 is the first T::H version to cause the breakage.Version
2.65_02 is ok.
That gives me something to work with.
Thanks, Nicholas.
Cheers,
Rob
