-# Bugs in perl
-
-There is a bug in perl's putenv which makes it interact badly with fakeroot-tcp and fakeroot-sysv (not fakeroot-hurd), this shows up as this
-
- *** glibc detected *** /usr/bin/perl: free(): invalid pointer: 0x01026000 ***
-
-See http://rt.perl.org/rt3/Ticket/Display.html?id=91452 for details
-
-A workaround is to do this before building packages calling perl inside fakeroot:
-
-export FAKEROOTUID=0 FAKEROOTEUID=0 FAKEROOTSUID=0 FAKEROOTFUID=0 FAKEROOTGID=0 FAKEROOTEGID=0 FAKEROOTSGID=0 FAKEROOTFGID=0

- <Dom> pinotree: so, with your three fixes applied to 5.14.2, there are
- still 9 tests failing. They don't seem to be regressions in perl, since
- they also fail when I build 5.14.0 (even though the buildd managed it).
- <Dom> What do you suggest as the way forward?
- <Dom> (incidentally I'm trying on strauss's sid chroot to see how that
- compares)
- <pinotree> Dom: samuel makes buildds build perl with nocheck (otherwise
- we'd have no perl at all)
- <pinotree> which tests still fail?
- <Dom> ../cpan/Sys-Syslog/t/syslog.t ../cpan/Time-HiRes/t/HiRes.t
- ../cpan/autodie/t/recv.t ../dist/IO/t/io_pipe.t ../dist/threads/t/libc.t
- ../dist/threads/t/stack.t ../ext/Socket/t/socketpair.t io/pipe.t
- op/sigdispatch.t
- <Dom> buildds> I see
- <pinotree> ah ok, those that are failing for me even with my patches
- <Dom> I hadn't spotted that the builds were done with nocheck.
- <Dom> (but only sometimes...)
- <Dom> Explains a lot
- <pinotree> syslog is kind of non-working on hurd, and syslog.t succeeds in
- buildds (as opposted to crash the machine...) because there's no /var/log
- in chroots
- <pinotree> libc.t appears to succeed too in buildds
- * Dom notices how little memory strauss has, and cancels the build, now
- that he *knows* that running out of memory caused the crahses
- <pinotree> iirc HiRes.t, io_pipe.t , pipe.t and sigdispatch.t fails because
- of trobules we have with posix signals
- <pinotree> socketpair.t is kind of curious, it seems to block on
- socketpair()...
- * Dom wonders if a wiki page tracking this would be worthwhile
- <pinotree> stack.t fails because we cannot set a different size for pthread
- stacks, yet (similar failing test cases are also in the python test
- suite)
- <Dom> if there are problems which aren't going to get resolved any time
- soon, it may be worth a few SKIPs conditional on architecture, depending
- on how serious the issue is
- <Dom> then we'd get better visibility of other/new issues
- <Dom> (problems which aren't bugs in perl, that is)
- <pinotree> understandable, yes
- <pinotree> i think nobody digged much deeper in the failing ones yet, to
- actually classify them as due to glibc/hurd/mach
- <pinotree> (eg unlike the pipe behaviour in sysconf.t i reported)
-
-### 2011-11-26
-
- <pinotree> cool, my recvfrom() fix also makes the perl test recv.t pass

-# Part II
-
-Next, Hurd-specific features can be added. Add an interface to the
-language/environment for being able to do [[RPC]] calls, in order to program
-[[hurd/translator]]s natively in Perl.
