I hope this will save time to others wich struggle with setting up Eclipse+PyDev+GAE SDK, Windows environment and ot be able to step up in * default.py* with the PyDev debugger.
Using GAE, setting up a development environment is very tricky but I managed to set it up. That is what I came out with up to now. Instructions: Setting up Eclipse+PyDev+GAE, Windows 1) web2py trunk source, install under root/app, app.yaml -> configure for you GAE app. 2) your app - build under root/*app*/applications/*myapp. I*t is a matter of copy/paste to add/replace your app there. Copy *myapp *at separate folder like backup/*myapp *and you can use bitbucket for source control. It has a free private hosting for up to 5 collaborators. 3) download GAE SDK source copy *google.appengine* directory on the same level as gluon - web2py will find for example *import google.appengine.ext * only that way. in your app.yaml exclude *google.appengine* directory explicitly. 4) set all GAE dependencies in *db.py *- when you fire up the debugger, the breakpoints stop in *db.py* but nowhere else ( a few places actually). 5) make function in *db.py:* def *MyHook()*: pass <-- set up a breakpoint in your Eclipse here. 6) in your *default.py* place *MyHook() *where you want a breakpoint to stop. Breakpoints doesn't stop anywhere else but a few places like *db.py. *I suppose default.py is run time compiled and does not works with source code. 7) in Eclipse point to root/*app - right click Debug As,* Properties - find the directory paths - add root/*app*/applications/*myapp *- so Eclipse can find your app source to stop in debugging. 8) run * Debug As,* Eclipse fires, your debugger stops at def *MyHook()*: pass <-- click with F5 to follow the link and you are in default.py, from there with F5 you can follow your code in default.py. Running with the debugger you can see where your code can be optimized. For example I mentioned 0.py, db.py, all files under models/ are loaded every time a link is visited. This slows down the execution and you will need to place everything db GAE related in db.py and 0.py. In 0.py you place the constants, in db.py - GAE db stuff. This is the most code separating wise can be made under web2py. Otherwise loading all these /models files every time slows things up in real usage mode.
