[Qemu-devel] [PATCH v6 0/7] convert sendkey to qapi

[Amos Kong]

This series converted 'sendkey' command to qapi. The raw value
in hexadecimal format is not supported by 'send-key' of qmp.

Amos Kong (7):
  fix doc of using raw values with sendkey
  monitor: rename keyname '<' to 'less'
  hmp: rename arguments
  qapi: generate list struct and visit_list for enum
  add the QKeyCode enum and the key_defs table
  add functions to convert key/code to index of mapping table
  qapi: convert sendkey

[Qemu-devel] [PATCH v6 1/7] fix doc of using raw values with sendkey

[Amos Kong]

(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.

[Qemu-devel] [PATCH v6 2/7] monitor: rename keyname '<' to 'less'

[Amos Kong]

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'.

[Qemu-devel] [PATCH v6 4/7] qapi: generate list struct and visit_list for enum

[Amos Kong]

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 lets qapi generate List struct for enum.

[Qemu-devel] [PATCH v6 5/7] add the QKeyCode enum and the key_defs table

[Amos Kong]

key_defs[] in monitor.c is a mapping table of keys and keycodes,
this patch added a QKeyCode enum and a new key_defs table,
Key's index in the enmu is same as keycode's index in new key_defs[].

Weird, I expected this would brake the build, as the new table is unused.

Anyway, what I suggested in my last review was to do the table move in a
different patch, which includes adding the new accessors, dropping key_defs
from the monitor and doing the necessary changes in the monitor functions
which access key_defs directly.

This way, the patch converting sendkey() to the qapi does just the
conversion itself (vs. conversion plus refactorings).

That's a side effect of 'const'.

Ok. I would split convert patch to two patches, and do the refactorings
in first patch.

[Qemu-devel] [PATCH v6 7/7] qapi: convert sendkey

[Amos Kong]

Convert 'sendkey' to use QAPI.

QAPI passes key's index of mapping table to qmp_send_key(),
not keycode. So we use two functions to convert key/code to
index of key_defs, and 'index' will be converted to 'keycode'
insider qmp_send_key().

For qmp, QAPI would check invalid key and raise error.
For hmp, invalid key is checked in hmp_send_key().

'send-key' of QMP doesn't support key in hexadecimal format.
