我正在远程机器上运行命令:

remote_output = run('mysqldump --no-data --user=username --password={0} database'.format(password))

我想捕获输出,但没有全部打印到屏幕上.最简单的方法是什么？

我将通过编写一个简单的fabfile 来安装check_mk插件:

from fabric.api import env, run, roles, execute, parallel

env.roledefs = {
    'monitoring': ['192.168.3.118'],
    'mk-agent': ['192.168.3.230', '192.168.3.231', '192.168.3.232']
}

@roles('monitoring')
def mk():
    run('[ -f check_mk-1.1.12p7.tar.gz ] || wget http://mathias-kettner.de/download/check_mk-1.1.12p7.tar.gz')
    run('[ -d check_mk-1.1.12p7 ] || tar zxvf check_mk-1.1.12p7.tar.gz')
    run('cd check_mk-1.1.12p7 && sudo ./setup.sh')

@parallel    
@roles('mk-agent')
def mk_agent():
    run('[ `rpm -qa | grep -c xinetd` -eq 0 ] && sudo yum -y install xinetd.x86_64')
    run('sudo rpm -ivh http://mathias-kettner.de/download/check_mk-agent-1.2.0b2-1.noarch.rpm') 

def check_mk():
    execute(mk)
    execute(mk_agent)

但是,正如您可以猜到的,如果xinetd已经安装了软件包,Fabric将停止并出现以下错误:

Fatal error: run() received …

我有一个用于构建本地存储库的宏debmirror.

这是代码片段:

{%- set gnupghome = kwargs.pop('gnupghome', '/root/.gnupg') %}
{%- set env = { 'GNUPGHOME': gnupghome } %}

  cmd:
    - run

由于这个设置:

git-completion.zsh并git-completion.bash在运行时自动安装brew install git：

/usr/local/share/zsh/site-functions包括在fpath：

由于某些原因，有时当我输入git reba并按下tab：

? git reba
__git_func_wrap:3: : not found

? type __git_func_wrap
__git_func_wrap is a shell function from /usr/local/share/zsh/site-functions/git-completion.bash

s3cmdepel-testing通过运行从repo 安装:

yum --enablerepo epel-testing install s3cmd

然后我调用了配置工具,s3cmd --configure但是我收到了这个错误:

我正在尝试使用Sparkle和Qt(绑定Go)应用程序.

sparkle.m:

#import <Headers/SUUpdater.h>

static SUUpdater* updater = nil;

void sparkle_checkUpdates()
{
    if (!updater) {
        updater = [[SUUpdater sharedUpdater] retain];
    }

    [updater setUpdateCheckInterval:3600];
    [updater checkForUpdatesInBackground];
}

sparke.go:

// +build darwin windows

package main

/*
#cgo CFLAGS: -I ${SRCDIR}/Sparkle.framework
#cgo LDFLAGS: -F ${SRCDIR} -framework Sparkle

void sparkle_checkUpdates();
*/
import "C"

func sparkle_checkUpdates() {
    C.sparkle_checkUpdates()
}

在main.go,我添加了一个菜单来调用该函数:

package main

import (
    "github.com/therecipe/qt/widgets"
)

func main() {
    action := widgets.NewQMenuBar(nil).AddMenu2("").AddAction("Check for Updates...")
    // http://doc.qt.io/qt-5/qaction.html#MenuRole-enum
    action.SetMenuRole(widgets.QAction__ApplicationSpecificRole)
    action.ConnectTriggered(func(bool) { …

v3.0.1我的同事在更新之前推送了一个标签go.mod以具有/v3后缀（https://github.com/golang/go/wiki/Modules#releasing-modules-v2-or-higher）。我已更新模块路径 ( go.mod) 和所有导入路径 ( *.go) 来修复它，标记为v3.0.2。

现在的问题是：

go get -v git.example.com/owner/repo@v3.0.2
go: finding git.example.com/owner/repo v3.0.2
go: git.example.com/owner/repo@v0.0.0-20190722053407-d85c4f69ad17: go.mod has post-v0 module path "git.example.com/owner/repo/v3" at revision 
d85c4f69ad17

发现这个：go build 不断抱怨：go.mod has post-v0 module path

因此，我删除了v3.0.0和v3.0.1标签，将其指向最新的提交，重新推送，但问题仍然存在。

我注意到go.mod仍然将旧版本称为间接依赖项：

require (
    git.example.com/owner.repo v0.1.2 // indirect

即使我改了它/v3 v3.0.2也会v0.1.12自动恢复。

为什么？

我错过了什么？
