error: refactor common hint-pattern into a common base class
I'm about to make another exception class require hints, so third
strike and you refactor.
i18n-pt_BR: synchronized with
2664f536a97e
util: allow to specify buffer size in popen4
We will need unbuffered IO to restore real time output with ssh peer.
Changeset
ec171737aaf1 seems to indicate playing with this value could be
dangerous, but does not indicate why.
sshpeer: extract the forward output logic
We are about to make a more aggressive use of this when reading and writing on
the other pipes. We it needs to be reusable.
sshpeer: break "OutOfBandError" feature for ssh (BC)
When we'll be using the ssh's 'stderr' for realtime output successfully, it will
no longer be possible to use 'stderr' to carry the error message (because it
is already consumed by the real time output logic.
This feature is very rarely used (test says largefile only) and I think
breaking its output pattern is worth the benefit of having real time output with
ssh.
