While investigating something else - 'change' QMP command for
the cdrom/floppy code, I noted the QMP schema lists the change
command as being deprecated for use with cdrom/floppy and changing
the VNC password. Further digging found that the existing set_password
QMP command would make the same call to change the password (qemu
API vnc_display_password) as long as "keep" was defined for connected
(which must be true for VNC). So altered the code to use the newer
command if available.
John Ferlan (4):
qemu: Alter current VNC set password to be legacy
qemu: Clean up formatting in virQEMUCapsCommands
qemu: Add change-vnc-password capability
qemu: Add support for change-vnc-password

New subject: [libvirt] [PATCH 1/4] qemu: Alter current VNC set password to be legacy
The QEMU "change" QMP command interface is being deprecated
according to qapi-schema.json, so this patch will keep the
current API available for legacy/older QEMU binaries with a
future patch introducing the newer change-vnc-password QMP
command interface.

New subject: [libvirt] [PATCH 4/4] qemu: Add support for change-vnc-password
Rather than use the to be deprecated "change" command, use the
change-vnc-password command to perform VNC password changes instead
of the set_password command. Since changing VNC password only
accepts "keep" for connect and that's the default, no sense in
vectoring through "set_password" as we've already checked that the
XML 'connected' was set to "keep" in virDomainGraphicsAuthDefParseXML.

Currently, we try 'set_password' first, and if that's not present
we fallback to the legacy "change" method. This is fine because
all QEMU since 0.14 have supported "set_password", so we only
need 'change' for really ancient QEMU. "set_password" works with
both SPICE and VNC.
The "change-vnc-password" method was only introduced in 1.1 QEMU,
so there's never a situation where we would not have "set_password"
and yet have "change-vnc-password".
I'm rather puzzelled why "change-vnc-password" was added to QEMU
at all, since it seems to be entirely less functional than
'set_password' which already exists. Thus I don't see any benefit
in using it from libvirt.

Daniel

Currently, we try 'set_password' first, and if that's not present
we fallback to the legacy "change" method. This is fine because
all QEMU since 0.14 have supported "set_password", so we only
need 'change' for really ancient QEMU. "set_password" works with

The "change-vnc-password" method was only introduced in 1.1 QEMU,
so there's never a situation where we would not have "set_password"
and yet have "change-vnc-password".
FWIW: When set_password was introduced, rather than go with capability
checking - the code checks for error of CommandNotFound and falls back
to the old "change" command.
I'm rather puzzelled why "change-vnc-password" was added to QEMU
at all, since it seems to be entirely less functional than
'set_password' which already exists. Thus I don't see any benefit
in using it from libvirt.
Having the value of connected as "keep" is the only way set_password
works for VNC:
set_password(...)
...
if (strcmp(protocol, "vnc") == 0) {
if (fail_if_connected || disconnect_if_connected) {
/* vnc supports "connected=keep" only */
error_setg(errp, QERR_INVALID_PARAMETER, "connected");
return;
}
...
I can only assume the change-vnc-password was introduced to avoid the
need to use set_password and passing "keep" for connected if provided.
Maybe a secondary goal is/was to allow VNC password processing not have
to worry about other changes in set_password. Who knows - my desire to
chase that history is next to nil.
I can drop the series - it doesn't really matter beyond just seeing the
"change" is deprecated. In the long run both have the same
functionality, it's just the change-vnc-password is more direct. The
virDomainGraphicsAuthDefParseXML also checks for "keep", so in the long
run everything is a wash. In the hindsight of hypervisor specific
checks the ParseXML check probably should be in some qemu specific checker.
