Redis EVAL command is used to evaluate scripts using the Lua interpreter. The first argument of EVAL is a Lua 5.1 script and the script does not need to define a Lua function. It is just a Lua program that will
eval5不支持use strict严格模式, 在非严格下的函数中this默认指向的是全局作用域,但在eval5中是undefined, 可通过globalContextInFunction来设置默认指向。 import{ Interpreter }from"Interpreter";constctx = {};constinterpreter =newInterpreter(ctx); interpreter.evaluate(` this; // ctx function func(){ return...
举个例子,对于上图所示的lua_scripts字典,以及上图所示的repl_scriptcache_dict字典来说,我们总可以将下面的EVALSHA命令: 改写成下面的EVAL命令: 其中脚本的内容如下图所示,来源于lua_scripts字典“5332031c6b470dc5a0dd9b4bf2030dea6d65de91”键的值: ④传播EVALSHA命令的方法 当主服务器成功在本机执行完一个EV...
因此,任意一个eval的使用都会强制浏览器进行冗长的变量名称查找,以确定变量在机器代码中的位置并设置其值。 另外,新内容将会通过eval()引进给变量, 比如更改该变量的类型,因此会强制浏览器重新执行所有已经生成的机器代码以进行补偿。 但是,(谢天谢地)存在一个非常好的eval替代方法:只需使用window.Function。 这有...
在为脚本定义函数,并且将脚本保存到lua_scripts字典之后,服务器还需要进行一些设置钩子、传入参数之类的准备动作,才能正式开始执行脚本。整个准备和执行脚本的过程如下: ①将EVAL命令中传入的键名(key name)参数和脚本参数分别保存到KEYS数组和ARGV数组,然后将这两个数组作为全局变量传入到Lua环境里面 ...
However, while some caching of compiled scripts may happen this will only be limited to scripts that are eval'd repeated with no modification. A more likely scenario is that you are eval'ing scripts that have undergone slight modification each time and as such could not be cached. Let's ju...

Always prefer JSON.parse() over eval() for parsing JSON to avoid executing malicious scripts.Security and Performance ConcernsUsing eval() can pose significant security risks and performance issues. Here’s why:Security Riskseval() can execute any JavaScript code, making it vulnerable to injection ...
