XML-RPC文档转换服务器
cloudooo的Python项目详细描述
安装cloudooo
$ python2.6 setup.py install
- Warnings:
- you must have installed setuptools>=0.6c11 in this python.
安装libreoffice/openoffice.org
- Install LibreOffice or OpenOffice.org.
创建配置文件
The configuration file is used to start the application using paster. $ cp ./cloudooo/samples/samples.conf . # Copy to current folder
- The next step is define some attributes in cloudooo.conf:
- working_path - folder to run the application. This folder need be created.
- uno_path - folder where UNO library is installed (ex. /opt/libreoffice/basis-link/program/)
- soffice_binary_path - folder where soffice.bin is installed (ex. /opt/libreoffice/program/)
运行应用程序
$ paster serve ./cloudooo.conf
or run as a daemon:
$ paster serve ./cloudoo.conf –daemon
停止应用程序
$ kill -1 PASTER_PID
Warning: always use SIGHUP because only with this signal all processes are stopped correctly.
cloudooo描述
- xmlrpc+wsgi将是方便访问libreoffice/openoffice.org的一个桥梁。这将在wsgi（paster）中实现一个xmlrpc服务器。
- pyuno用于连接libreoffice/openoffice.org，它使用open socket声明。这些功能都将由pyuno处理。
- 只有一个进程可以访问libreoffice/openoffice.org。
- 当连接到xmlrpc服务器时，所有客户端都接收相同的对象（代理）。
管理libreoffice/openoffice.org流程
- start ‘soffice.bin’; - Pyuno start ‘soffice.bin’ processes and the communication is through sockets; - ‘soffice.bin’ processes run in brackground;
- control ‘soffice.bin’; - If the socket lose the connection, cloudooo kills the process, restartes processes and submit again the file;
xmlrpc服务器-xmlrpc+wsgi
- Send document to ‘soffice.bin’ and return the document converted with metadata;
- XMLRPC receives a file and connects to ‘soffice.bin’ process by pyuno;
- The pyuno opens a new document, write, add metadata and returns the document edited or converted to xmlrpc and it return the document to the user;
- When finalize the use of ‘soffice.bin’, should make sure that it was finalized;
- Export to another format;
- Invite document and return metadata only;
- Edit metadata of the document;
- Problems and possible solution
- ‘soffice.bin’ is stalled; - finalize the process, start ‘soffice.bin’ and submit the document again(without restart the cloudooo);
- ‘soffice.bin’ is crashed; - finalize the process, verify if all the process was killed, start ‘soffice.bin’ and submit the document again(without restart the cloudooo)
- ‘soffice.bin’ received the document and stalled; - if ‘soffice.bin’ isn’t responding, kill the process and start
- The document that was sent is corrupt; - write in log the error and verify that the process aren’t in memory
