How do I change which GitHub project I forked from?

由 人走茶凉 提交于 2019-12-17 22:29:24
问题 I forked a project, made some changes, and got a pull request accepted. But now, the project I forked moved to another repository and is a fork of that repository. That is: Original -> MyFork Now: NewOriginal -> Original -> MyFork How would I get it to the following? NewOriginal -> MyFork 回答1: Locally you can just change the target of the original repository is located at. Usually that repository is called upstream , so you would do this: git remote set-url upstream git://example.com

一、本地同步fork的最新版本 二、git命令 一、本地同步fork的最新版本 ①打开Git CMD工具，进入git的主目录 ②使用 git remote -v 查看fork的远程仓库地址 origin：为我fork的远程仓储的名字 paySource：为原项目github地址（需要使用命令 git remote add paySource git@github.com:octocat/Spoon-Knife.git 添加进来） ③执行 git fetch paySource 命令，检出paySource分支以及各自的更新 ④切换到你的本地分支主干 git checkout master ⑤合并paySource/master分支和master分支,将原项目中的更改更新到本地分支，这样就能使你的本地的fork分支与原项目保持同步，命令: git merge paySource/master ⑥执行 git push 将本地分支的修改推送到远端fork的项目 二、git命令 设置用户名和email $ git config --global user.name "Your Name" $ git config --global user.email "email@example.com" ------------------- 将目录变成Git可以管理的仓库 $ git init -

pcntl_fork and the MySQL connection is gone

由 心已入冬 提交于 2019-12-17 19:32:50
问题 I have a foreach loop that forks within it. After the process forks, it accesses the database. I get an error: SQLSTATE[HY000]: General error: 2006 MySQL server has gone away The thing is, I'm connecting to the database after I've forked. My question: Why would this be happening? If this happens, am I actually accessing the database before forking? Will the child inherit DB connections? (note: I can post code, but it's rather large as it's all in classes, which could be what is causing my

How to pass arguments to processes created by fork()

由 a 夏天 提交于 2019-12-17 18:51:59
问题 I want to create copies of a process using fork() in C. I cant figure out how to pass arguments to the copies of my process. For example,I want to pass an integer to the process copies. Or I what to do, if I have a loop in which I call fork() and want to pass a unique value to processes (e.g. 0...N) for (int i = 0; i < 4; ++i) { fork(); // pass a unique value to new processes. } 回答1: The nice part about fork() is that each process you spawn automatically gets a copy of everything the parent

Returning data from forked processes

问题 If I do Process.fork do x end how can I know what x returned (e.g. true/fase/string) ? (Writing to a file/database is not an option...) 回答1: We actually just had to handle this problem in Rails isolation testing. I posted about it some on my blog. Basically, what you want to do is open a pipe in the parent and child, and have the child write to the pipe. Here's a simple way to run the contents of a block in a child process and get back the result: def do_in_child read, write = IO.pipe pid =

1. 安装GDB增强工具 (gef) 　　* GDB的版本大于7.7 　　* wget -q -O- https://github.com/hugsy/gef/raw/master/scripts/gef.sh | sh 　　* 确保网络连通 并且成功更新ubuntu (更新source.list 使用apt-get update) 2. GDB安装插件(在root权限安装,用户权限使用不了需要在用户权限下安装) 　　git clone https://github.com/gatieme/GdbPlugins.git ~/GdbPlugins　　(安装gdb的Python脚本插件) 　　切换gdb模式 : 　　echo "source ~/GdbPlugins/peda/peda.py" > ~/.gdbinit　　　　(默认打开gdb插件是pada)　　倾向于破解和逆向 　　echo "source ~/GdbPlugins/gef/gef.py" > ~/.gdbinit　　　　　　倾向于debug 逆向 　　echo "source ~/GdbPlugins/gdbinit/gdbinit" > ~/.gdbinit　　　　个人定制 3.Linux程序发布流程 　　* 确定程序是否存在符号表 　　　　readelf -s test-1 　　* 生成符号表 　　　

Fork parent child communication

由 ℡╲_俬逩灬. 提交于 2019-12-17 17:58:29
问题 I need some way for the parent process to communicate with each child separately. I have some children that need to communicate with the parent separately from the other children. Is there any way for a parent to have a private communication channel with each child? Also can a child for example, send to the parent a struct variable? I'm new to these kind of things so any help is appreciated. Thank you 回答1: (I'll just assume we're talking linux here) As you probably found out, fork() itself

Difference between pthread and fork on gnu/Linux

由 浪尽此生 提交于 2019-12-17 17:29:50
问题 What is the basic difference between a pthread and fork w.r.t. linux in terms of implementation differences and how the scheduling varies (does it vary ?) I ran strace on two similar programs , one using pthreads and another using fork, both in the end make clone() syscall with different arguments, so I am guessing the two are essentially the same on a linux system but with pthreads being easier to handle in code. Can someone give a deep explanation? EDIT : see also a related question 回答1: In

Forking vs Threading

由 落花浮王杯 提交于 2019-12-17 17:28:32
问题 I have used threading before in my applications and know its concepts well, but recently in my operating system lecture I came across fork(). Which is something similar to threading. I google searched difference between them and I came to know that: Fork is nothing but a new process that looks exactly like the old or the parent process but still it is a different process with different process ID and having it’s own memory. Threads are light-weight process which have less overhead But, there

Create a daemon with double-fork in Ruby

由 左心房为你撑大大i 提交于 2019-12-17 17:26:53
问题 What is the proper way to create a well-behaved Unix or Linux daemon in Ruby? What is the definition of a well-behaved daemon anyway, and how would one write such a program in Ruby? 回答1: According to Stevens's Advanced Programming in the UNIX Environment chapter 13, this is the procedure to make a well-behaved Unix daemon: Fork and have the parent exit. This makes the shell or boot script think the command is done. Also, the child process is guaranteed not to be a process group leader (a
