python – 从代码中的某个点跟踪所有语句

2019年8月4日 224次阅读

我试图在复杂的
Python应用程序(OpenERP)中跟踪调用和代码的流程.为了使它更复杂,OpenERP有自己的继承系统,与普通的Python继承并行.

我想要做的是拥有一个完整的代码列表,包含模块/函数名称.

我已经尝试过Eclipse调试器,我理解pdb的工作原理大致相同,但是单步调试过程需要很长时间.

我也尝试使用跟踪启动应用程序,但是在我想要跟踪的点之前我得到了太多不必要的跟踪.我确实尝试排除模块和目录,但它没有多大帮助.

python -m trace -t --ignore-dir=/home/sean/unifield/utp729b/unifield-server --ignore-dir=/home/sean/unifield/utp729b/unifield-web --ignore-module=SocketServer,socket,threading,tiny_socket,__init__,trace,netsvc,posixpath,zipfile,config,genericpath,orm openerp-server.py --db_host=localhost --db_port=5432 --db_user=openerp --db_password=xxxx --addons-path=/home/sean/unifield/utp729b/unifield-addons,/home/sean/unifield/utp729b/sync_module_prod,/home/sean/unifield/utp729b/unifield-wm > /home/sean/trace.log

我想要做的是在代码中设置一个断点,但不要再单步执行代码,然后开始记录到文件.

我也试过使用装饰器,例如http://eli.thegreenplace.net/2012/08/22/easy-tracing-of-nested-function-calls-in-python/和http://code.activestate.com/recipes/577551/,但它们并没有满足我的需求.

我现在尝试使用Python跟踪模块,将此行添加到Eclipse中的VM Arguements框中：-m trace -t –trace

这开始产生我正在寻找的东西,逐行跟踪,但是当OpenERP完全启动时停止工作.请参阅下面的控制台输出中的(冗长)提取.

看一个更强大的解决方案,但总是运行而不是一个时间点的解决方案,在这里：Finding full pathname in a Python trace

最佳答案 我不知道如何像你想要的那样设置跟踪;我能提供的是,大多数与存储和检索数据有关的有趣调用都通过… / openerp / osv /目录中的osv.py,fields.py和orm.py进行.
