Type: defect.
Priority: major
Component: I/O
Verison: 5.92
It is unclear to me how one would implement get-bytevector-some.
I don't think it can be implemented reasonably using the read
call-back function of make-custom-binary-port. The best I can think
of: allocated some largish buffer, call the read call-back, and
the re-allocate a new bytevector with however many bytes were
actually read. But that still won't return "a freshly allocated
bytevector of non-zero size containing the available data" -
just "a freshly allocated bytevector of non-zero size containing
*part* of the available data". And it means allocating a
temporary large bytevector and throwing it away.
Fix: remove get-bytevector-some, or clarify that it
reads "one or more of the available characters". I suggest
the former.
