This series converted 'sendkey' command to qapi. The raw value
in hexadecimal format is not supported by 'send-key' of qmp.
Amos Kong (6):
fix doc of using raw values with sendkey

Changes from v1:
- using a JSON array for the key names
- rename new error to 'QERR_OVERFLOW'
- fix command descriptions
- qapi: generate list struct for enum
- add '<' fixing
Changes from v2:
- fix support of raw value in hexadecimal format
- fix bug in processing of '<-x'
- don't generate useless cleanup functions for enum
- introduced two functions for enum in qapi scripts
- fix command description
- drop keys number limitation in sendkey
- drop patch: qerror: add QERR_OVERFLOW

(qemu) sendkey a
(qemu) sendkey 0x1e
(qemu) sendkey #0x1e
unknown key: '#0x1e'
The last command doesn't work, '#' is not requested before
raw values. And the raw value in decimal format is also not
supported.

There are many maps of keycode 0x56 in pc-bios/keymaps/*
pc-bios/keymaps/common:less 0x56
pc-bios/keymaps/common:greater 0x56 shift
pc-bios/keymaps/common:bar 0x56 altgr
pc-bios/keymaps/common:brokenbar 0x56 shift altgr
This patch just renames '<' to 'less', QAPI would add new
variable by adding a prefix to keyname, '$PREFIX_<' is not
available, '$PREFIX_less' is ok.
For compatibility, convert user inputted '<' to 'less'.

Currently, if define an 'enum' and use it in one command's data,
List struct for enum could not be generated, but it's used in
qmp function.
For example: KeyCodesList could not be generated.
>>> qapi-schema.json:
{ 'enum': 'KeyCodes',
'data': [ 'shift', 'alt' ... ] }
{ 'command': 'sendkey',
'data': { 'keys': ['KeyCodes'], '*hold-time': 'int' } }
>>> qmp-command.h:
void qmp_sendkey(KeyCodesList * keys, bool has_hold_time, int64_t
hold_time, Error **errp);
This patch makes qapi can generate List struct for enum.

Convert 'sendkey' to use QAPI. do_sendkey() depends on some
variables/functions in monitor.c, so reserve qmp_sendkey()
to monitor.c
key_defs[] in console.h is the mapping of key name to keycode,
Keys' index in the enmu and key_defs[] is same.
'send-key' of QMP doesn't support key in hexadecimal format.

I don't think we need 'name', as key names are also provided by KeyCodes_lookup[].
See more on this below.

We can't have an array defined in a header file because it will be defined in
each .c file that includes it.
Please, define it in input.c (along with qmp_send_key()) and write the following
public functions:
o KeyCode keycode_from_key(const char *key);
o KeyCode keycode_from_code(int code);
and then use these functions where using key_defs would be necessary. Also,
note that keycode_from_key() can use KeyCodes_lookup[] instead of key_defs (this
way we can drop 'name' from KeyDef).

This check is not needed, as far as I can understand only qmp_send_key() can put
keys in the keycodes list and qmp_send_key() does this check already.

Please set keycodes to NULL here. Actually, you'll have to free it first,
because keycodes has to be duplicated (see below).

Let's initialize key_timer here, like this:
if (!key_timer) {
key_timer = qemu_new_timer_ns(vm_clock, release_keys, NULL);
}
Then drop the initialization done in monitor_init(). This way we untangle
qmp_send_key() from the monitor.
Also, please, move qmp_send_key(), release_keys, etc to input.c as I said
above.

It's better to this assignment after the for loop below. Actually, you have to
duplicate the key list because the qapi code will free it as soon as
qmp_send_key() returns, but it will be used later in the timer handler.

Yes, I tried to define key_defs[] to a int array, and get keyname from
KeyCodes_loopup[],
it works.

[KEY_CODES_SHIFT] = 0x2a,

Ok.

void qmp_send_key(KeyCodesList *keys, bool has_hold_time, int64_t

\_ when we use qmp, a key list will be passed, the
values are the index
in enum KeyCodes. not the real KeyCode.
{ 'enum': 'KeyCodes',
'data': [ 'shift', 'shift_r', 'al...
So we need to get this kind of 'index' in hmp_send_key() and pass to
qmp_send_key().
then convert this 'index' to keycode in qmp_send_key()
I didn't find a way to define a non-serial enum.
eg: (then int qmp_marshal_input_send_key() would pass real keycode to
qmp_send_key())
{ 'enum': 'KeyCodes',
'data': [ 'shift' = 0x2a, 'shift_r' = 0x36, 'alt' = 0x38, ...
If we still pass 'index' to qmp_send_key as patch V4.
extern int index_from_key(const char *key); -> it's used in hmp_send_key()
extern int index_from_keycode(int code); -> it's used in hmp_send_key()
extern char *key_from_keycode(int idx); -> it's used in
monitor_find_completion()
extern int keycode_from_key(const char *key); -> it's used in qmp_send_key()

If we find one invalid 'value', other keys in the list will be ignored.
so we don't need to release them here.

^^ If an invalid key is found, the other keys will be ignored.
Will fix other issues you mentioned, thanks for your review.

Yes, that's what keycode_from_key() would do, something like this:
KeyCode keycode_from_key(const char *key)
{
int i;
for (i = 0; i < KEY_CODES_MAX; i++) {
if (!strcmp(key, KeyCode_lookup[i])) {
return i;
}
}
return KEY_CODE_MAX;
}
Note that it returns the KeyCode index, and should be defined in input.c.
> then convert this 'index' to keycode in qmp_send_key()
Exactly, qmp_send_key() can access key_defs[] to get the keycode from the
index.

I'm not sure I follow you here, I think that what I suggested above will work.

That should be done in qmp_send_key(), only valid keys should be passed to

Well, that's the behavior I'd expect. Maybe we should loop twice. First
we check everything is ok and then we trigger the key down events.
Now, the current code doesn't do this and I'm not sure if we would
break compatibility... I'll let you choose what you think is best.

So I would continually pass 'index' to qmp_send_key().
I already implemented those in localhost, they all works.
Will fix other issues and post v5 later, thanks.
