[Ps2hacking-devel] apt and fakeroot, beware of buggy PS2 Linux Kit

Yesterday and today, I sat down and compiled apt and fakeroot. I found 
out some strange things.

1. Apt

  Compiled nicely out of the box and seemed to be working, except it
  complained when msync(2)ing to save pkgcache.bin . A strace shoewed
  that the arguments to msync(2) were correct (PAGESIZE boundary) so
  I assume the implementation of msync(2) was broken and got rid of
  that part in apt/apt-pkg/contrib/mmap.cc by checking for __R5900
  That's really ad-hoc. The problem is that mipsEEel doesnt' support
  seem to  msync(2) but still declaeds _POSIX_SYNCHRONIZED_IO, which is a
  POSIX violation.


2. fakeroot

  Compiled like it was a nice dream. But dream was dream. It barfed
  on rm during "make -C test". A little search revlealed that it was
  doing an endless loop in libfakeroot.c:unlink(). next_unlink() was
  calling libfakeroot's unlink() agin and that caused an segfault after
  30230 iterations on my machine. A dummy program doing just unlink()
  (together with open/close/lstat/fstat) worked fine. After not being
  able to figure the problem out, I compiled rm freshly from
  Debian's fileutils. That solved the problem, the new rm worked fine.
  I'm really puzzled as the old one didn't have any problem unless
  run in fakeroot. Maybe the old rm had been crosscompiled and had
  weired symbols ??

  fakeroot now passes "make -C check" but somthing still isn't right.
  "fakeroot dh_testroot" passes, but a dh_testroot inside debian/rules
  when called like "fakeroot debian/rules binary" doesn't.
  Also 
	perl -e 'print "a$<a"'
  gives correct uid's as a normal user aswell as root, but 
	fakeroot perl -e 'print "a$<a"'
  
  doesn't produce any output at all. Checking for $< is exactly what
  dh_testroot is doing. Anybody got any idea's ?

Also, I currently have  glibc-2.2.2-1, fileutils-4.1, dpkg-1.9.15, apt-0.5.3
as .debs . Plus a likely broken fakeroot-0.4.4


Happy Hacking!
