Subject: Re: [9front] [PATCH] awk: don't write an extra NUL past the end of a block
Date: Tue, 23 Jan 2024 11:50:59 -0600	[thread overview]
Message-ID: <b6b8797a-c1d0-427a-8fd2-b349f5e995e3@posixcafe.org> (raw)
In-Reply-To: <F056E68DACC66F58F358BC3E2E6D2983@wopr.sciops.net>

On my linux machine:
# nawk is onetrueawk
; dd </dev/zero bs=4 count=8k | tr '\0' A | nawk '{a=$1}'
8192+0 records in
8192+0 records out
32768 bytes (33 kB, 32 KiB) copied, 0.00933006 s, 3.5 MB/s

This works fine. No crash. I am not doubting this needs fixed,
I am doubtful of fixing it in this way being correct. It is still
not clear to me if there is some other input that is relying on
that extra line to be there. But it is clear that onetrueawk fixed
this using some other fix.

We should figure out how they solved it and/or prove that the cases
in which those loops never run are impossible to hit.
