Re: CVS problem with ssh

[Richard M. Stallman]

      Currently CVS does a single select on the stdout fileno
    before dumping as much data as it last received from the network to
    stdout via fwrite.  There is *no looping or checking for EAGAIN
    returns*, which I believe you advocated but, I am informed by Larry
    Jones and Paul Eggert, would likely be unportable to non-GNU systems.

What do you mean by "unportable"?  As far as I can see, that change
could not do any harm on any system.  If it fixes the problem on GNU
systems, that's an important improvement, so why not do it?

So would you please install that change?

      I would much prefer to be able to
    rely on stdio for a situation like this.

It sounds like you can rely on stdio on a GNU system.  If other
systems don't handle this reliably, maybe that is their fault.  You
could report bugs in fwrite if they fail to write the data and don't
return EAGAIN.
