[Spice-devel] [PATCH v4 3/6] server/red_{record, replay}.[ch]: introduce
Frediano Ziglio
fziglio at redhat.com
Wed Aug 19 07:39:04 PDT 2015
From: Alon Levy <alon at pobox.com>
Currently hand crafted with some sed scripts and alot of vim macros from
red_parse_qxl after considering the logger in qemu/hw/qxl-logger.c and seeing
it was incomplete. The only problem with logging from the server and
not from qemu is that it requires coordinated shutdown to avoid half a message.
Should be automatically generated from a declarative syntax, i.e. qxl.proto.
Note: zlib compression is introduced in a disabled state, see ZLIB
define
Now with a simple versioned header and generated ids by the server
instead of based on the recorded file, and doesn't use more then 1024
surfaces (configurable).
