lo-runner's Introduction

Loco program runner core

We use this python-c library to run program in a sandbox-like environment. With it, we can accurately known the resource using of the program and limit its resource using including system-call interrupt.

Usage

For run a program without tracing:

runcfg = {
    'args':['./m'],
    'fd_in':fin.fileno(),
    'fd_out':ftemp.fileno(),
    'timelimit':1000, #in MS
    'memorylimit':20000, #in KB
}

rst = lorun.run(runcfg)

For check one output:

ftemp = file('temp.out')
fout = file(out_path)
crst = lorun.check(fout.fileno(), ftemp.fileno())

trace

You can set runcfg['trace'] to True to ensure runner's security.

Here is a simple usage:

runcfg['trace'] = True
runcfg['calls'] = [1, 2, 3, 4] # system calls that could be used by testing programs
runcfg['files'] = {'/etc/ld.so.cache': 0} # open flag permitted (value is the flags of open)

在判java题时报错

系统版本 Ubuntu18.04.3
java版本:

openjdk version "11.0.4" 2019-07-16
OpenJDK Runtime Environment (build 11.0.4+11-post-Ubuntu-1ubuntu218.04.3)
OpenJDK 64-Bit Server VM (build 11.0.4+11-post-Ubuntu-1ubuntu218.04.3, mixed mode, sharing)

runcfg:

{
	"args": ["java", "./judge/0561e20b5577d0affdeee205975d9279/Main"],
	"fd_in": 4,
	"fd_out": 5,
	"timelimit": 5000,
	"memorylimit": 20000
}

运行时出现错误:

Error: failed /usr/lib/jvm/java-11-openjdk-amd64/lib/server/libjvm.so, because libm.so.6: failed to map segment from shared object

直接使用 java ./judge/0561e20b5577d0affdeee205975d9279/Main是可以正常运行的
请问该如何处理才能运行出正确答案?

Presentation Error when using 'rU' open mode

Some code:

fin = open(inFile, 'rU')

inFile is data from MySQL Database, and this data is from PHP textarea input by user.
I use vim to see the inFile, and find ^M at the end of each line.
So I use 'rU' open mode instead of 'r'.
But when lo-runner compare between answer and user out file, it gives out Presentation Error.
Out file doesn't have ^M.

RLIMIT_DATA和 RLIMIT_AS的选择

我看你的项目使用的是 setrlimit(RLIMIT_DATA, &rl) 来限制内存的，而 hustoj 的判题端使用的是RLIMIT_AS，代码在 https://github.com/zhblue/hustoj/blob/master/trunk/core/judge_client/judge_client.cc#L1565

我的理解是RLIMIT_DATA就只能限制代码数据段的内存占用，比如代码中已经定义的数组，而RLIMIT_AS是限制了整个进程的虚拟地址空间，也能控制 malloc 或者 new 的内存了。

不知道我理解的对么，你选择 RLIMIT_DATA 的理由是什么呢？谢谢

本项目开源协议是什么？

打算借鉴一部分代码。

谢谢。

想知道有木有trace功能的白名单

写了个vj想要添加一个插件支持，变成 vj && oj 双混合模式，基本差不多但是不知道哪些system calls该放行，看了hustoj的源码［大雾，Ubuntu Server 15.10 32位 0.0

So 来请求帮助了 😂

emmm...小白有个安装问题

用python setup.py instll 安装后在python里import lorun 的时候报错找不到.lorun_ext模块是为什么呢。。？求教..谢谢

利用centos7.3 计算出来的运行时间和内存使用，出入挺大的

MAC 上无法编译成功，好像是因为 sys/user.h文件和linux不一样

沙盒中（python）调用其他库

请问，我在沙盒中使用python的import numpy的时候发现会调用失败。
好像所有的import操作都会失败。目前找了好久也没找到原因。
所以想问一下作者，我想在执行的程序里面import其他库应该怎么做？
出错信息：

64位Ubuntu下内存读不准

lorun在32位系统下表现很好，然而在64位Ubuntu下（我测试了12.04和14.04两个LTS版本），都会出现内存读不准的问题，请问有什么方法可以解决么？

怎么设置files参数？

我在设置中这样设置，
runcfg['trace'] = True
runcfg['calls'] = [0,1,2,3,5,9,10,11,12,21,59,158,231]
runcfg['files'] = {'/etc/ld.so.cache': 0}
然而运行时返回的结果是RE，具体如下
{'re_file': '/etc/ld.so.cache', 'memoryused': 156, 'result': 5, 'timeused': 0, 're_file_flag': 524288}
求问这个files参数是什么意思？应该怎么设置？

PE after latest commit

... When I start using latest version of Lo-runner...
There are all 'PE' status

But using 537af2c is OK.
