-0777 broken in 1.8.1?

ruby-talk
1

Version 1.8.0:

$ ruby -0777 -ne 'puts $FILENAME' .bash*
.bash_history
.bash_profile
.bashrc
.bashrc.funcs
.bashrc.mine
.bashrc.ode

Version 1.8.1:

$ ruby -0777 -ne 'puts $FILENAME' .bash* 
.bash_history
.bash_history
.bash_history
.bash_history
.bash_history
.bash_history
.bash_history
.bash_history
.bash_history
.bash_history
...

It appears that gets no longer proceeds to the next input file
automatically when $/=0777. (Tested on x86 and alpha)

Can’t reproduce on my machine (i686-linux). Can you show us more info
about your platform and exact version (including date) of your interpreter?

ruby 1.8.1 (2003-12-25) [i686-linux-gnu] <<< actually an Athlon-XP
CFLAGS=“-mcpu=athlon-xp -O3 -pipe”

ruby 1.8.1 (2003-12-25) [alphaev67-linux-gnu]
CFLAGS=“-mcpu=alphaev67 -mieee -O3 -pipe”

I can built ruby 1.8.0 (2003-08-04) on the same platforms with the same
CFLAGS and it works fine.

Which compiler do you use? When I use -mcpu=athlon-xp -O3 -pipe and try
the test suite on my Mandrake 9.2 I get errors, but if I turn the
optimisation down to -O2 it works. Using a stable snapshot from last
night (just because I was looking at it and have a build script)

If I run that then all goes well, and the runner.rb finishes up with

If I change -O2 to -O3 then I see this in the out

  1. Error:

When I run the test suite. Maybe it’s an optimisation problem. I only
looked at it for a few minutes before work this morning as I was
thinking about using the same compiler flags on ruby as on perl.

Hope this helps,

Mike

I’m using gcc-3.3.2. I just tested with -O0 but the problem persists.
The fact that it appears with 1.8.1 (on two architectures) but not with
1.8.0 suggests that it should be possible to narrow down some related
source changes within ruby.

I ran into this with 1.8.1 last week, where the end-of-file was not
being detected when the input record separator is null. This seems to
have been fixed in io.c (on 26 December 2003). It now works correctly in
the CVS version:

~/src/ruby-1.8.0% ./ruby -v; ./ruby -0777 -ne ‘puts $FILENAME’ ran*
ruby 1.8.0 (2003-06-23) [i686-linux]
random.c
random.o
range.c
range.o

~/src/ruby-1.8.1% ./ruby -v; ./ruby -0777 -ne ‘puts $FILENAME’ ran*
ruby 1.8.1 (2003-12-25) [i686-linux]
random.c
random.c

~/src/ruby-cvs/ruby% ./ruby -v; ./ruby -0777 -ne ‘puts $FILENAME’ ran*
ruby 1.9.0 (2004-02-06) [i686-linux]

Thanks Jeff! That does the trick! Sounds like 1.8.2 should be right
around the corner… :wink:
