Subject: [9fans] Strange rc bug for the 9fans bug-squashing squad
Date: Tue, 17 Mar 2009 00:26:57 +0100 [thread overview]
Message-ID: <5d375e920903161626o78226952j8a6088c1373cfbe3@mail.gmail.com> (raw)
At first I thought very big rc variables seem to become strangely corrupted.
% for(i in `{seq 1000}) { echo 0123456789 >> f }
% ifs='' {x=`{cat f}}
% echo -n $x > f2
% diff f f2
745c745
< 0123456789
---
> 01234567 9
But the bug seems to be in `{ } because replacing the use of the x var
with simply:
% ifs='' { echo -n `{cat f} > f2}
Produces the same results.
Longer strings get more random(?) characters 'blanked'.
The results are identical in p9p and native plan9.
I looked a bit around the rc source that seemed relevant, but didn't
see any obvious errors, but I don't fully understand the code.
Peace
