Dear, maintainers. Installation goes wrong on Windows XP. It seems that it will happen if 'Guard' ver.1.0 or heigher is installed. I cannot judge whether a true cause is 'Guard', of course it's because 'Guard' is not used for P::A::Proxy.(And you know the author of 'Guard' is the MLEHMANN... how to explain to him this ...) There is possibility of that a cause is 'AnyEvent(::HTTP)' or 'Plack::*::AnyEvent*'. regards, kpee ================================================= OS: Windows XP sp3 (MSWin32-x86-multi-thread) Perl Version: 5.16.1 (Strawberry Perl) Module Version: Plack::App::Proxy 0.22 Test::Requires 0.06 Plack 1.0009 IO::Socket::INET 1.33 ExtUtils::MakeMaker 6.6302 AnyEvent::HTTP 2.14 Test::More 0.98 Test::TCP 1.17 LWP::UserAgent 6.04 HTTP::Headers 6.00 Case 1: test without 'Guard' @dmake test C:\strawberry\perl\bin\perl.exe "-MExtUtils::Command::MM" "-e" "test_harness(0, 'inc', 'blib\lib', 'blib\arch')" t/*.t t/*/*.t t/00-load.t ......................... 1/1 # Testing Plack::App::Proxy 0.22, Perl 5.016001, C:\strawberry\perl\bin\perl.exe t/00-load.t ......................... ok t/basic.t ........................... ok t/deflate.t ......................... skipped: Test requires module 'Plack::Middleware::Deflater' but it's not found t/filter_headers.t .................. ok t/middleware/addvia.t ............... ok t/middleware/connect.t .............. ok t/middleware/loadbalancer.t ......... ok t/middleware/rewrite-auto_guess.t ... ok t/middleware/rewrite-guess_fails.t .. ok t/middleware/rewrite.t .............. ok t/status.t .......................... ok All tests successful.

Thank you for tracking this down! I've been bothered by the lone failing test on Windows but was unable to test. I've mentioned it to MLEHMANN before but without more details he wasn't able to help. Hopefully he'll be more responsive with these details.

Could you try this workaround and see if it gets the tests passing for you? https://github.com/leedo/Plack-App- Proxy/commit/08c1004fc948bbc82f2d83e681abf7b6a4bdabde Thanks!

I tried your code on 'GitHUB'(with 'Guard-1.022'), but test FAIL.

Thanks for giving it a try. One more thing, could you try running the tests like so: PERL_ANYEVENT_AVOID_GUARD=1 make test Thanks! -- Lee

After discussing this with the AnyEvent author, it sounds like this failure is caused by perl's fork emulation on Win32 and memory corruption. I've disabled this test for MSWin32, so tests should now pass with 0.24.
