help installing Devel::NYTProf under Cygwin

Special_K has asked for the wisdom of the Perl Monks concerning the following question:

I am trying to install Devel::NYTProf under Cygwin using CPANM and am seeing the following failure in the build log:

t/44-model.t ............. ok

#   Failed test '$! should not be altered by NYTProf i/o'
#   at t/50-errno.t line 58.
#          got: '0'
#     expected: '3'
# Looks like you failed 1 test of 8.
t/50-errno.t ............. 
Dubious, test returned 1 (wstat 256, 0x100)
Failed 1/8 subtests

How do I fix this? Here is the complete (collapsed) build log:

G'day Special_K, I tried the installation myself and got the same result. I edited my CPAN Tester Report as follows: ------------------------------ TESTER COMMENTS ------------------------------ Additional comments from tester: I'm following up a question on PerlMonks: "help installing Devel::NYTProf under Cygwin" (https://www.perlmonks.org/?node_id=11135967). The error I have below is identical to the one posted on PerlMonks. The "CPAN Testers Matrix: Devel-NYTProf 6.10 (latest distribution)" (http://matrix.cpantesters.org/?dist=Devel-NYTProf+6.10) only has one report for Cygwin (https://www.cpantesters.org/cpan/report/a4dfd892-7306-1014-8def-c9dd7 +5d8a230) which is an identical FAIL. I see from https://github.com/timbunce/devel-nytprof/blob/master/t/50- +errno.t that the problem line is in a SKIP block: skip ... if($^O eq 'VMS'); Unless that test is essential for Cygwin, perhaps consider: skip ... if($^O eq 'VMS' or $^O eq 'cygwin'); [download] The CPAN Testers Matrix typically takes a while to update: my report may not appear for some time (which is why I posted it here). I hope there's sufficient information for you to see what's going on; ask if that's not the case. Given you got very close to success: `Failed 1/55 test programs. 1/4949 subtests failed.` [download] I'd recommend you take the `force` option. Update: Force worked for me. `cpan[2]> force install Devel::NYTProf ... JKEENAN/Devel-NYTProf-6.10.tar.gz /usr/bin/make install -- OK` [download] — Ken	[reply] [d/l] [select]

> I hope there's sufficient information for you to see what's going on; ask if that's not the case. The section of code that is failing is: `SKIP: { skip 'On VMS buffer is not flushed', 1 if ($^O eq 'VMS'); cmp_ok $size1, '>', 0, "$nytprof_out should not be empty"; }` [download] Is SKIP just an arbitrary label? What does 'skip' do? How do I know if this test is safe to skip for Cygwin?	[reply] [d/l]

Re^3: help installing Devel::NYTProf under Cygwin by kcott (Archbishop) on Aug 21, 2021 at 05:25 UTC
"The section of code that is failing is ..." That statement is completely wrong. Your own OP has: `# Failed test '$! should not be altered by NYTProf i/o' # at t/50-errno.t line 58.` [download] The URL I provided (https://github.com/timbunce/devel-nytprof/blob/master/t/50-errno.t) links to code with line numbers. The SKIP block starting at line 50, and ending on line 59, contains "`t/50-errno.t line 58`". "Is SKIP just an arbitrary label?" No, it's not. Probably the most frequently used test module is the core Test::More (wherein you'll find `SKIP`). If you're going to investigate "`.t`" files, you should be familiar with this module; although, be aware that there are many other modules in the `Test::` namespace. I'm a strong advocate of testing and would recommend that you read up on `Test::More` anyway. "How do I know if this test is safe to skip for Cygwin?"* The short answer is: "you don't". A longer answer would, to some extent, depend on your definition of "safe". It's a developer's tool so your clients will be unaffected. If you are genuinely concerned, don't use this module. — Ken	[reply] [d/l] [select]
