Subject: [RFC][PATCH] ProcessPipe.pm: Use read not sysread
Date: Mon, 30 Jul 2018 00:04:45 -0500 [thread overview]
Message-ID: <87y3dtl3f6.fsf@xmission.com> (raw)
While playing with git fast export I discovered that mixing <> and
read would give inconsistent results. I tracked the issue down to
using sysread in ProcessPipe instead of plain read.
If it is desirable to use readline I can't see how using sysread
can work as readline to be efficient needs to use buffered I/O.

Am I missing something or was this a fundamental bug from the beginning?
