小试Plone-5.1.6下用collective.celery支持collective.documentviewer 5.0.4的异步转换，效果仍不理想

---------------------------------------------------------------------------------------------------------------------------

首先抛出结论：异步转换效果仍不理想， 两年前collective.documentviewer 5.0.1就有的两个毛病还是没解决

收获也有：

一是保存了可用的pin组件versions组合，

二是试了一下用flower查看celery信息，至少可以知道有哪几个文件异步转换失败

#其他值得探索的功能及需求
#一、异步支持
#上传一个文件时，转换预览很慢，collective.documentviewer同时支持plone.app.async和
#collective.celery进行异步转换，上传时可以迅速返回，实际转换在后台运行，还可以查看进度，
#但是网上的文章都是Plone4的，只找到一篇Plone5使用collective.celery的文章。

写上一篇博文时在Plone-5.1.2下对collective.documentviewer 5.0.1异步转换的尝试效果并不理想，所以没写进正文

一是同时上传的多个文件异步转换有的成功有的不成功，但是对不成功的文件单独转换：点开单个文件->“操作”->“文档管理系统转换”又可以转换成功

二是本应支持查看转换进度的“admin”->“网站设置”->“Document Viewer Async Tasks”直接无效，导致到底有哪几个没转换成功还必须一个个点开检查。

而Plone-4.3.18下用app.plone.async异步转换collective.documentviewer 4.0.14，则完全没有上面两个毛病。

由于这个功能涉及的方面太多，根本搞不清楚是redis-server的问题还是collective.celery或collective.documentviewer的问题，当时还试图不用redis-server，改用celery[sqlalchemy]或celery[librabbitmq]，结果网上一篇文章都找不到，只好打消了这个念头。

其实在pypi.org中可以看到collective.celery和collective.documentviewer的作者是同一个人vangheem，我印象中曾经看到过此人在文章中承认collective.celery有一个和异步转换部分失效相关的issue还没有解决，和我当时记下的出错提示相符，但这篇文章网址当时没记下来，出错提示也没记下来。

---------------------------------------------------------------------------------------------------------------------------

快两年了，现在Plone-5.2版本都出来了，Plone开始进入Python3、Zope4的时代了

当前最新的5.1（old-stable）版本是Plone-5.1.6了。

我心想，再尝试的时间窗口基本上到了，技术继续迭代下去，最新组件将全面支持Plone-5.2，逐渐会抛弃Plone-5.1，再想pin住那么多组件的versions，只会越来越困难了。这次尝试不用最新版本，采用Plone-5.1.6+collective.documentviewer 5.0.4的组合。

一方面Plone-5.1.6使用的还是Zope 2.13，而Plone-5.2已经是Zope4时代了

目前网上找到的唯一能解决中文ID问题的组件https://github.com/wichert/experimental.utf8id要求Zope 2.13.20 or later。

（我在Plone-4.3.18中经过尝试，可以用https://github.com/wichert/experimental.utf8id    加上

https://pypi.org/project/c2.patch.filenamenormalizer    的组合解决中文ID问题）

另一方面collective.documentviewer最新6.0.0 (2020-05-12)版本都已经不用docsplit了

Changelog
6.0.0 (2020-05-12)
...
...
Replaced docsplit. Instead call the various packages directly. See pull request #79. [alphaomega325]

我在Plone-4.3.18 中已经依赖docsplit切割出的文本，实现了目录列表时截取每条前几十个汉字文本，搜索结果时取出每条中关键字前后文（其中关键字用不同背景颜色高亮突出显示）分别列示在每个条目下方的功能。本次尝试的重点是异步转换，就不再引入新特性新版本了，免得节外生枝。

一、安装redis-server

apt-get -y --force-yes install redis-server

二、install.sh安装后改/opt/plone/zeocluster/buildout.cfg，在buildout.cfg同一目录中patch -p0 <buildout516.cfg.diff

三、改/opt/plone/zeocluster/base.cfg，在base.cfg同一目录中patch -p0 <base516.cfg.diff

四、我试过了，collective.documentviewer 5.0.4不改convert.py在debian-7.11.0-amd64下仍然出错。避免走弯路，先改好。

改/opt/plone/buildout-cache/eggs/collective.documentviewer-5.0.4-py2.7.egg/collective/documentviewer/convert.py，在convert.py同一目录中patch -p0 <convert504.py.diff，完成后删除或改名同一目录中的convert.pyc和convert.pyo，这次没改出错信息编码出错的部分，哈哈

五、其他参照上一篇博文，不能漏掉任何部分，buildout完成后要开四个终端并su为root权限（标准的做法是引入supervisor来启动各组件，原型测试就不学该怎么写buildout.cfg启动supervisor了）。前三个都滚屏显示，第四个会回到命令提示符下

分别在桌面开四个终端，都su为root权限
root@mydebian204:/opt/plone/zeocluster# bin/pcelery worker parts/client2/etc/zope.conf
root@mydebian204:/opt/plone/zeocluster# bin/flower --address=0.0.0.0 --port=5555 --broker redis://127.0.0.1:6379
root@mydebian204:/opt/plone/zeocluster# bin/tika-server
root@mydebian204:/opt/plone/zeocluster# bin/plonectl start

管理员登录建一个站点：http://10.16.97.204:8080/Plone，安装组件ftw.tika，collective.documentviewer组件，配置collective.documentviewer组件加入按文件类型自动布局"Word Document"。选某个目录，点“内容”-“上传”，从磁盘目录中拖动一批文件到上传区域-点"上传“按钮，在客户端浏览器打开http://10.16.97.204:5555可以见到flower的界面，点task可以看到当前进度。测试中出现State没有变成“SUCCESS”就说明没有异步转换成功。记下文件名，还可以单独转换，点开单个文件->“操作”->“文档管理系统转换”一般都可以转换成功。有时传三个文件就有一个没转换，传更多时又可能全部转换成功，就这么不着调儿

六、原型测试结束，我决定还是继续用Plone-4.3.18了，不折腾Plone5了

---------------------------------------------------------------------------------------------------------------------------

记下文件名时会发现文件名都是ASCII码和数字构成，而不是中文文件名。

我在Plone-4.3.18中经过尝试，可以用https://github.com/wichert/experimental.utf8id    加上

https://pypi.org/project/c2.patch.filenamenormalizer    的组合解决中文ID问题

本文中buildout.cfg中也加入了experimental.utf8id的内容，但是全部注释掉了

中文ID在Plone-5.1下有兴趣的读者可以试一下，

方法就是下载experimental.utf8id-master.zip，解压到/opt/plone/zeocluster/src，更名为experimental.utf8id，取消buildout.cfg所有experimental.utf8id前的注释符，再运行buildout

警告一下：批量上传就开始和中文ID就有冲突了，其他肯定还会有很多issue，要想实用肯定要修改experimental.utf8id组件以外的代码

（而Plone-4.3.18中用wildcard.foldercontents批量上传支持中文ID完全没有问题）
