Debugging Frappe with PyCharm

Frappe Framework App Development
1

Hi Everyone
Trying to debug the Frappe for the first time, followed this link Pycharm Debugging - #5 by hpema108
put a line break in init.py. The complier breaks fine and I can step through the code. The problem is I am getting
Permission denied: ‘/home/frappeuser/frappe-bench/logs/bench.log’
when I run through __init__py, deleted bench.log and started again still to no avail.

Traceback (most recent call last):
File “/usr/lib/pycharm/helpers/pydev/pydevd.py”, line 1580, in
globals = debugger.run(setup[‘file’], None, None, is_module)

not sure why. Now I can run bench start fine from frappeuser folder.

OK I actually logged in as FrappeUser on my ubuntu desktop, configured PyCharm for the frappe user and ran debug bench and all started fine.
I want to step through more code, not sure which file I should place a breakpoint immediately after bench start. your help much appreciated.

Please refer 17/22 in the following thread, you may find it useful

Thanks Pawan, I made some progress using the link from Fellipeh in my original post. I am still trying to find my way through, looking for the entry point to Frappe just after bench start,

@CoffeeHolic,

check app.py, all the requests are processed by application method.

Thanks, Makarand

Thanks Makarand, finally I see some light at the end of the tunnel, spot on mate.
Actually these are my settings
script: /usr/local/bin/bench
params: start
python interpreter: python 2.7.6
working dir : /home/frappuser/frappe-bench
put break points in bench and cli.py and the compiler breaks HOWEVER, when I debug app.py it does not break. It goes past through and starts bench. I posted a screen shot of the break point in app.py - I added print ‘here’ in app.py,

I see it in the console log but IT DOES NOT BREAK. It is really a great start,
