Windows does not like me - why?

[Ingo Lantschner]

Hi all,
I have 2 modules in CPAN, which get tested since several weeks.
http://matrix.cpantesters.org/?author=lanti

For some reason they do not get tested on specific operating systems
f.e. Windows. Is there some technical reason for this (or is this just a
question of sympathy - which would be reciprocal in some cases :-) )?

Cheers - Ingo

My quick test of Backup::SingleFile fails because Test::File fails.
Because a prerequisite failed, no reports about Backup::SingleFile are
sent.

You can check your dependency tree on different operating systems here:

27. Test::File No results
28. Test::Manifest No results

I wonder why Test::Manifest has no test results?

[David Golden]

I don't know.

The sad thing about Test::Files is that a bug was opened three
*years* ago, a patch was giving two and a half years ago, and yet it's
still broken.

Hum. Can anyone provide a link listing what CPAN modules use
"Test::Manifest" in their test suite? Maybe that and Test::Files
should be avoided...

[David Golden]

CPANTS should have a list of modules that use them.

Whoops! I now note a difference between

Test::Files

and

Test::File

and note from CPANTS very sparse information on both:

Test-Files-0.14 (PHILCROW)

Used by 4 other dists
used by Kwalitee PauseID
App-MaMGal 100.00% PORRIDGE
Bigtop 130.44% PHILCROW
HTML-Encapsulate 121.74% NPW
Maildir-Lite 104.35% DEIAN

and

Test-File-1.29 (BDFOY)
Used by 0 other dists
used by Kwalitee PauseID
none found

It doesn't. It has six passes.

CPANTS is meant to be able to tell you that, but appears to be horribly
out-of-date.

It should be fairly easy to patch CPANdeps to figure it out, but I lack
tuits. Have at it:
http://www.cantrell.org.uk/cgit/cgit.cgi/cpandeps/

What may not be obvious from the code is that you can rely on all the
META.yml files being cached, as I now do that as a batch job (see
getfiles.sh and populate-cache.pl). There are still some mathoms in
lib/CPANdeps.pm for fetching them, but you can ignore that.

The patch should probably go in populate-cache.pl.

ok, thanks for this hint. I looked into Test::File and saw, that it
always fails on Win32. Looking in one of the reports I found lines like
this one:

[...]
ok 1 # skip file_is_symlink_ok doesn't work on systems without symlinks!
[...]
Failed test 'Is multi user'
[...]

Since my Windows-knowldege is quite outdated, I am not sure but I guess
that the test from Test::File do not consider Windows to be a multi-user
system (which is not true, for Windows NT 3.x and later). Smylinks may
still not be supported by Windows and its NTFS. So probably the best
would be to file a bug against Test::File or to remove Test::File from
my module (which means that I have to remove or rewrite several test).
Any other/better idea?

Thanks, Ingo

Symlinks are only supported by Windows Vista and later (2008 Server, 7),
and then only on supporting filesystems (NTFS).

You could do *both*. :)
