emacs30 remote server出现epc error invalid-function

[norris-young]

最近想试下emacs30,然后发现有问题.
local用法正常,remote用法出现epc error invalid-function.
emacs -Q 用下面的方式配置就可以复现,同样的方式emacs29没有问题.

这个error我在lsp-bridge仓库里没搜到,不知道是不是python epc报的错?所以不知道咋定位了

另外我看emacs30好像有个news是内置了json support,没有--with-json了,不知道有没有影响.

编译版本:

GNU Emacs 30.0.92 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.20, cairo version 1.16.0) of 2024-12-07

编译选项:

"--with-native-compilation=aot --with-tree-sitter --without-compress-install 'CFLAGS=-march=native -O2'"

确实和json的改动有关系，逻辑上在lsp_bridge_server的情况下，sexp好像套了2次[]

lsp-bridge/core/utils.py

Lines 190 to 208 in 520d253

	def eval_in_emacs(method_name, *args):
	global lsp_bridge_server
	if test_interceptor: # for test purpose, record all eval_in_emacs calls
	test_interceptor(method_name, args)
	args = [sexpdata.Symbol(method_name)] + list(map(handle_arg_types, args)) # type: ignore
	sexp = sexpdata.dumps(args)
	logger.debug("Eval in Emacs: %s", sexp)
	# Call eval-in-emacs elisp function.
	if lsp_bridge_server and lsp_bridge_server.file_command_server:
	lsp_bridge_server.file_command_server.send_message({
	"command": "eval-in-emacs",
	"sexp": [sexp]
	})
	else:
	epc_client.call("eval-in-emacs", [sexp]) # type: ignore

lsp-bridge/lsp_bridge.py

Lines 609 to 612 in 520d253

	def handle_lsp_message(self, message):
	if message["command"] == "eval-in-emacs":
	# Execute emacs command from remote server.
	eval_sexp_in_emacs(message["sexp"])

lsp-bridge/core/utils.py

Lines 477 to 478 in 520d253

	def eval_sexp_in_emacs(sexp):
	epc_client.call("eval-in-emacs", [sexp])

我去掉1次[]改成下面这样，emacs30就正常了

def eval_sexp_in_emacs(sexp):
    epc_client.call("eval-in-emacs", sexp)

大佬， 多测试一下， 如果几天没毛病， 欢迎发送补丁。

感谢大佬的详细调查。

[manateelazycat]

eval-in-emacs 是可以支持Elisp函数和函数参数的， 如果去掉 [] 会导致很多地方调用Elisp函数参数的地方都会出错。

我感觉更像是Emacs那边兼容性破坏的问题， 等正式版发布再看看吧
