The next patch wants to add some sanity checking, which would

report OOM failure if virBuf reports an error, and this will be
wrong in the (unlikely) case that they actually had a usage error
instead; but since the most common error really is ENOMEM, I'm
not going to fix all callers. Meanwhile, new discriminating
callers can react differently depending on what failure happened.
* src/util/buf.c (virBufferSetError): Add parameter.
(virBufferGrow, virBufferVasprintf, virBufferEscapeString)
(virBufferEscapeSexpr): Adjust callers.
After you rebase to current head, this patch omits to modify
an call instance of virBufferSetError in the newly introduced
function virBufferEscapeShell resulting into:
util/buf.c: In function 'virBufferEscapeShell':
util/buf.c:563: error: too few arguments to function 'virBufferSetError'
Yep, I caught that one in my local rebase before reading your mail.
I looked trhough all instances of calling virBufferError and found
none, that would check against a constant, so after this patch, everything
should work as it used to. Even if it has now access to a reason of the
error.
ACK with that fixed
Thanks; pushed.
