LabVIEW 2020 发布后的一些吐槽汇总

LabVIEW 2020 离线镜像下载出错的解决办法

NI的官网使用CloudFlare的CDN加速，国内使用的是百度云加速，因此继承了百度不靠谱的特质，经常发现下下来的hash值和NI官方给的hash值对不上。
这种情况下推荐重新下载一遍，有时候hash就能对上了。
如果反复下载之后，几次的hash都对不上，这时候就可以用变通的办法来处理。
解压缩离线的ISO镜像后
目录下会有Install.exe,一些DLL支持文件，目录有以下三个：
1. bin（安装支持文件包含了NI包管理器和.net安装环境）
2. feeds（目录下包含子目录如ni-488.2，再下一层有Packages文件）
3. Pool（包含了实际的nipkg安装包）

Packages文件是纯文本的，里面包含了Pool目录下的nipkg文件的一些信息。

里面比较重要的是Filename和MD5Sum两个字段，可以用来确认nipkg文件是否已经损坏。
为了修复安装包，需要根据这个配置文件把损坏的nipkg文件找出来，然后替换成好的。
目前看来只要是文件名一致的nipkg文件并且没有损坏，hash应该是一致的，所以可以用其他完好安装包里的nipkg文件进行替换。
经过我实验，Pool里面将损坏的nipkg文件替换为正常的nipkg文件，安装包就可以正常安装使用。

PS:
另外在C:\Program Files\National Instruments\NI Package Manager下有一个nipkg.exe可以创建离线安装包，可惜的是不支持校验和修复已经下载好的安装包,希望NI以后可以加上对应的功能。

        LabVIEW 2020 新特性
社区版简介教程
Getting Started with LabVIEW 2020 Community Edition

https://learn.ni.com/training/resources/1407/getting-started-with-labview-2020-community-edition
https://learn.ni.com/training/resources/1407/courses/11523/take?locale=en_US
新出社区版，免费非商业使用，不能打包EXE。
支持Linx工具包，支持树莓派等Target
https://ekerry.wordpress.com/2019/11/20/introducing-labview-2020-community-edition-beta-free-for-non-commercial-use/
原来的Home版被Community取代
新特性
对类的增强，可以显示多重继承了。

增加NI Web Server同时维护Application Web Server。
打包增加了对SystemLink的优化。
其他都是细节增强，
比如很多窗口界面可以调整大小。
错误窗口优化了层级关系等等
断线只清理有问题的部分。
VI的增改主要是增加了
NI Web Server相关的部分，还有加密和哈希的VI。
另外发现一个NI平台软件包2019Fall 32bit版本（对应LabVIEW 2019 SP1 32bit）下载的问题，每次下载下来的hash值都不一样，和NI官方hash对比也不一样，安装时会报安装包损坏。
用文件比较工具对比，发现集中在visa驱动部分，用64bit的镜像文件里面的同名文件替换后可以正常工作。
        网络排故记录
前言
自疫情以来发现网络情况很不稳定，发现虚拟专网时有链接不上的情况。

网络拓扑
上海 WAN1 联通光纤固定IP+ WAN2 电信PPPOE 

通过飞塔防火墙软件定义网络宽带合一访问外网
飞塔防火墙在 WAN1 提供IPSEC隧道，WAN2提供SSL虚拟专网服务
西安 WAN1 联通专线固定IP+WAN2 电信PPPOE
通过飞塔防火墙软件定义网络宽带合一访问外网
飞塔防火墙在WAN1 拨号到IPSEC隧道以访问上海的内网资源
故障现象1
西安WAN1的IPSEC隧道失败，但可以用客户端SSL虚拟专网访问。

故障确认：
使用TraceRT发现上海WAN1的固定IP无法Ping通，

故障原因：
是联通网络问题。




    

故障现象2
IPSEC隧道正常，使用客户端SSL虚拟专网无法访问。客户端在忽略证书错误后就无法再连接上。

故障确认：
使用Web界面可以用账号密码正常登录，确认网络通讯正常，账号密码正常。

更换机器也可以正常连接。卸载当前版本飞塔客户端重装无效，但更换版本后可以正常工作，如从5.6升级到6.2，或者从6.2降级到5.6都可以。
故障原因：
怀疑是注册表或者配置文件出错。

故障现象3
IPSEC隧道失败，客户端拨SSL虚拟专网失败。

故障确认：
Web界面无法打开，确认网络不通。

故障原因：
上海端电信PPPOE拨号失败。

故障现象4
IPSEC连接失败，客户端SSL虚拟专网随机性断开。

故障确认：
飞塔CPU占用100%，经过测试，只要下载速度超过10MB/s，防火墙就没有响应。查询手册，UDP包最大速率1.5Gbps，防火墙策略 5000 SSL虚拟专网吞吐量 30Mbps，IPS吞吐量只有200Mbps也就是20MB/s但实际上测试只要到10MB/s的下载速度，CPU就已经100%了。

故障原因：
防火墙IPS性能不足

 查了一下，防火墙IPS指的是防火墙的处理能力
Most vendors talk of firewall throughput even when they are advertising UTMs (Unified Threat Management Systems). There’s a fundamental difference between a firewall and a UTM. A firewall merely does stateful inspection of the traffic whereas a UTM proactively stops attacks even on allowed ports because it contains the all important IPS (Intrusion Prevention System). This means that even if traffic is allowed to certain services, that traffic is continuously examined to detect malicious attacks. In other words, the IPS stops hacker attacks even on open ports.
KB2538242反复安装解决办法：手动安装
下载 KB2538242
Microsoft Visual C++ 2005 Service Pack 1 Redistributable Package MFC Security Update
https://www.microsoft.com/en-us/download/details.aspx?id=26347
安装 KB2538242 会提示安装路径错误，估计是打包计算机的默认路径

手动选择到本机对应路径，安装完成后重启。
一句话说明：搜索结果可以用Auto summary字段列出高亮关键字
详细说明：
自Win7以来库功能让索引搜索向大众普及了不少，不过Win10的搜索有一个很大的倒退就是搜索结果摘要从两行变成了一行
变通的办法就是使用详细视图代替摘要视图，然后显示Auto summary字段即可，只要你屏幕足够宽就可以显示的比内容视图要多
另外 Windows 10 1909更新把搜索栏换成了UWP所以经常挂掉，解决的办法就是任务管理器里面重启explorer：
如果是土豪的话，可以购买Agent Ransack或者File Locator Pro作为替代方案，并且可以把搜索结果导出纯文本。
免费版的缺点是无法建立索引，不过文件量不大的情况下也基本上够用了。比Windows索引搜索的好处是对关键字和复合条件搜索支持更好。变通的办法就是先用Windows搜索筛选出来可能有结果的文件，复制到另一个目录，然后再用Agent Ransack lite导出结果。
最后是一个iOS的feature

看Readme，主要是修正了新加的数据类型相关的一些bug，如果发现LabVIEW Crash的问题，可以试试是否升级能够解决。

LabVIEW     2019 installs the LabVIEW Database Connectivity Toolkit and the LabVIEW     Report Generation Toolkit for Microsoft Office.
The     DataFinder Toolkit no longer exists. You can now find the functionality of     this toolkit on the DataFinder Connectivity palette in LabVIEW 2019.
In     2019, the Statechart Module moved to the LabVIEW Tools Network

        LabVIEW FPGA Vivado 编译器最小内存要求
记得刚开始用LabVIEW FPGA的时候还是在XP下，当时编译时爆内存不足简直是家常便饭。不过在大内存普及的今天我们来看一下到底多少内存足够编译器使用。

可以看到编译LabVIEW FPGA基本上有个16G内存就差不多了，除非要同时编译多个bitfile可能需要更大的内存。而Xilinx的Virtex UltraScale XCVU440峰值需要48G内存，这就只有上专业工作站才能满足了，或者考虑在Linux服务器上部署编译服务。
        LabVIEW 2019 已经发布
LabVIEW 2019其实在五月的NI Week就已经发布了,不过国内CDN(似乎是什么百度云加速)一直没有完成同步,导致下载不了完整的离线包.目前经过我测试至少LabVIEW 2019已经可以成功下载.

这次最大的改变就是完全使用NI Package格式进行发布,这样可以减小重复的组件占用的控件,像32bit的LabVIEW镜像只有26G.LabVIEW NXG 3.1也已经发布,不过还没办法成功下载离线包,如果着急下载的话,可以下64bit的软件平台安装包(SPB),里面包含了NXG,CVI,Measurement Studio,TESTSTAND等NI大部分软件.
SPB 2019      Sping和之前SPB不同的地方是把32和64bit软件分开了,因为NI 2021年就要停止32bit操作系统支持以及Win7和Win Server 2008 R2支持.
另外一个改变就是很多不是很常用的工具包已经移动到了VIPM里面.
在下载页面点击下载离线安装包就可以下载ISO格式的安装镜像

        LabVIEW调用Python返回数组时报错1671
最近在测试用LabVIEW和Python实现算法时的可替换性,正好LabVIEW 2018可以调用Python代码就方便了不少,可以直接替换比对.但是发现调Python时返回单个值的时候正常,返回一个数组时报错.

Error 1671 occurred at Python Node in PythonNode_PyIntegral.vi
Possible reason(s):
LabVIEW: (Hex 0x687) There was an error in executing the specified function.
Python returned the following error: <class ‘SystemError’>
..\Objects\listobject.c:186: bad argument to internal function
查了一下LabVIEW帮助,返回值应该是支持数组才对的啊?
仔细研究了一下发现了一条附注:
Calling Conventions
This node converts integers and strings to the corresponding data types in Python, converts arrays to lists, and converts clusters to tuples.
输入参数的时候有类型转换,那么是不是返回值的时候没有转换?
在python里打印了一下返回值的type,是np.ndarray,于是手动转换成list,果然就可以正常工作了.
        配置LabVIEW和TortoiseGit工作
首先安装git for windows和TortoiseGit,都使用默认安装即可.

主要的工作量是在于设置TortoiseGitMerge和TortoiseGitDiff

Configuring TortoiseGit for Graphical Diff
	1. Right-click in Windows Explorer to expose the TortoiseGit options
	2. Mouse-over ‘TortoiseGit>> Settings’
	3. In the list of settings on the left, select ‘Diff Viewer’,On the right side of the dialog, select ‘Advanced’
	4. When the ‘Advanced diff settings’ dialog appears, select ‘Add’
	5. In the dialog that appears, type .vi as the extension
	6. Where it prompts you for the path to the external program, type the following: “C:\Program Files\National Instruments\Shared\LabVIEW Compare\LVCompare.exe” %mine %base -nobdcosm -nobdpos
	7. Repeat this operation for the file-type .ctl
