fix: Use luajit by default when run APISIX CLI by fukiki · Pull Request #3335 · apache/apisix

fukiki · 2021-01-19T04:43:35Z

Signed-off-by: fukiki [email protected]

What this PR does / why we need it:

When run APISIX, use LuaJIT or Lua 5.1 by default.

If the local lua version is not 5.1, use openresty-luajit as default.

Fix : #3281

 	luarocks install rockspec/apisix-master-0.rockspec --tree=deps --only-deps --local
 endif
+ifneq ($(LUA_VER),Lua 5.1)
+	sed -i '' -e "s|#!/usr/bin/env lua|#!/usr/bin/env $(LUAJIT_DIR)/bin/luajit|g" ./bin/apisix


this is a hack way. it should not be enough.

here is another way, we can make a try:

#!/bin/sh # find the openresty, eg: which openresty ... # find the luajit of openresty ... # run the CLI of APISIX $luajit -e '...'

@membphis
I don't understand very clearly.
Do you mean to create a new shell script to judge whether to use lua5.1 or luajit when running the CLI of APISIX?
It could run the CLI of APISIX selectively: lua ./bin/apisix or luajit -e ./bin/apisix?

we can use a shell script to write the CLI, it'll to call luajit ./bin/apisix

@membphis Could you review commit 065a44 for me? Thank you.

By the way, about CI error: lua: /usr/bin/apisix.lua:3: unexpected symbol near '-' , the file apisix.lua is the same with old file apisix, no change, and I didn't find any reason about it, could you help me?

membphis

can we put this file bin/apisix.lua to apisix/cli?

fukiki · 2021-01-20T09:35:37Z

can we put this file bin/apisix.lua to apisix/cli?

apisix.lua is a part of cli, put it into apisix/cli will be better. Thanks.
I will modify it.

membphis · 2021-01-21T03:52:02Z

please merge the code of master branch, CI failed ^_^

fukiki · 2021-01-21T09:57:45Z

@membphis @tokers Please take a look when you have time.

-- modify the load path to load our dependencies
-package.cpath = pkg_cpath .. pkg_cpath_org
-package.path  = pkg_path .. pkg_path_org
+if [[ "$LUA_VERSION" =~ "Lua 5.1" && $USE_LUA ]]; then


this is wrong. we should always use luajit of openresty

+if [[ "$LUA_VERSION" =~ "Lua 5.1" && $USE_LUA ]]; then


this is wrong. we should always use luajit of openresty

if we always use luajit of openresty , it will be a big chage for old users . so we think maybe we should leave a way for old users ?

this is fine for the old users, sure for this

membphis · 2021-01-22T01:50:27Z

-                  .. apisix_home .. "/deps/lib/lua/5.1/?.so;;"
-local pkg_path = apisix_home .. "/deps/share/lua/5.1/?.lua;;"
+# find the openresty
+OR_EXEC=$(which openresty)


This step may fail, and we need to do some exception checks.

If the openresty command is not found, you can actively determine whether there is this directory in /usr/local/openresty.

thrown an error if failed to find the openresty

eg:

https://github.com/apache/apisix/blob/master/Makefile#L36

LGTM, ci failed, need you to process it

membphis · 2021-01-27T06:47:04Z

@spacewander told me that, this is a bug of openresty 1.15 or 1.17 .

do you have any suggestions about this?

luajit: lj_asm_x86.h:2819: asm_loop_fixup: Assertion `((intptr_t)target & 15) == 0' failed.
./bin/apisix: line 40: 24266 Aborted                 (core dumped) $LUAJIT_BIN $APISIX_LUA $*

spacewander · 2021-01-27T06:51:57Z

The problem occurs with openresty-debug. Since people might use openresty-debug package, the robust way is to avoid using LuaJIT unless you are using OpenResty 1.19.

fukiki · 2021-01-27T07:39:32Z

About the bug of openresty-debug, there are two suggestions:

Add conditions: when OpenResty version is not 1.19 , allow to use Lua 5.1
Modify document: introduce the bug , explain the reasons and solutions

I think this is fine. you can make a try ^_^

tokers · 2021-01-27T11:19:07Z

@fukiki I think the title can be changed :), we only want to run APISIX CLI with LuaJIT.

so cool @fukiki ~!

Since all checks have passed, pls take a look again at your convenience

LGTM, except minor style things

@tokers do you have time to look at this PR?

membphis · 2021-01-29T14:39:09Z


 - If you want use Tengine instead of OpenResty, please take a look at this installation step script [Install Tengine at Ubuntu](../.travis/linux_tengine_runner.sh).

+- By default Apache APISIX runs with luajit of OpenResty 1.19 (priority) or Lua 5.1. If you run in to an issue `luajit: lj_asm_x86.h:2819: asm_loop_fixup: Assertion '((intptr_t)target & 15) == 0' failed`, it is caused by to the compatibility of OpenResty version. OpenResty 1.19 is recommended, please take a look at this installation step script [linux-install-openresty](../utils/linux-install-openresty.sh).


Apache APISIX runs with luajit -> Apache APISIX runs with LuaJIT

@membphis I submitted about the style things.

tokers · 2021-01-29T14:41:13Z

 ifeq ("$(wildcard /usr/local/openresty-debug/bin/openresty)", "")
 	@echo "ERROR: OpenResty not found. You have to install OpenResty and add the binary file to PATH before install Apache APISIX."
 	exit 1
+else


What about echoing a warn message here?

@tokers The warn message will be better, I've submitted.

tokers · 2021-01-29T14:44:02Z
