Subject:

Failed tests in 09_duplicates

Most of the issues I reported in ticket 18137 are fixed in 0.12, but I'm still failing a few tests. Here's the output from make test: PERL_DL_NONLAZY=1 /usr/local/bin/perl "-MExtUtils::Command::MM" "-e" "test_harness(0, 'blib/lib', 'blib/arch')" t/*.t t/00_load............ok t/01_new.............ok t/02_insert..........ok t/03_lcs.............ok t/04_lrs.............ok t/05_clear...........ok t/06_remove..........ok t/07_memleak.........ok t/08_find............ok t/09_duplicates......dubious Test returned status 0 (wstat 11, 0xb) DIED.

hmm, errors are supposed to look like: t/09_duplicates......NOK 2 # Failed test 'return count of remove' # in t/09_duplicates.t at line 7. # got: '2' # expected: '1' # Looks like you failed 1 test of 13. make sure you have the latest Test::More installed. and try `make test TEST_VERBOSE=1`.

sorry, but that's not enough information to figure out what's going on. can you narrow it down further? a better test case may help. Show quoted text

I'll try, but I might not have time to try to debug this for a few days... Walt On Sun, Mar 19, 2006 at 08:54:50PM -0500, Guest via RT wrote: Show quoted text

OK, I've done some experimenting on my box with test 09_duplicates.t, and here's what I've found. If I trim it down to this: use strict; use Test::More tests => 3; use Tree::Suffix; my $tree = Tree::Suffix->new(qw(string bling string)); is($tree->strings, 3, 'string count'); # is($tree->remove(qw(string)), 2, 'return count of remove'); it runs fine: % perl -Iblib/arch -Iblib/lib t/walt.t 1..3 ok 1 - string count ok 2 - return count of remove # Looks like you planned 3 tests but only ran 2. But when I uncomment that third test, it segfaults on the *second* test! % perl -Iblib/arch -Iblib/lib t/walt.t 1..3 ok 1 - string count zsh: segmentation fault perl -Iblib/arch -Iblib/lib t/walt.t Bizarre, ain't it?

you actually have only two tests there. the first line is just the tree constructor and isn't a test. so the problem is straightforward- remove() is segfaulting for you. unfortunately i don't have access to a similar system so can't debug why it's only affecting you. can you run the few test programs that come with libstree and see if they work as expected to make sure the problem doesn't lie there. if that's not the source, i'll add some debug capability to the next release.
