After fixing many errors in the last PR. This is the error that has me stumped.
Looks like the start_time is not being decoded into an int properly. Please assist with pointers

[minorcong]

The start_time should be int according to https://github.com/baidu/Curve/blob/master/api/curve/v1/models/data_abstract.py#L29, Maybe it's helpful to run in debug mode, stop curve(free the port 8080) and debug api/profile.py

[navneeth]

The upload file is the example used here: https://github.com/baidu/Curve.

./control.sh start; tail -f api/log/*.log

@minorcong I appreciate if you can tell me how to invoke the code in pdb.
I am new to flask/ node.js.
Just discovered that uwsgi frameworks map stderr/stdout to null. So that putting an
import pdb; pdb.set_trace
does not trigger a debug prompt.
How do you recommend ?

[minorcong]

The application entry point is api/uwsgi.py. This maybe helpful https://github.com/baidu/Curve/blob/master/api/profile.py#L16

[navneeth]

@minorcong. I downgraded to python2.7 & the issue is fixed now.
Please correct the information in your README.md.

Dependency:
Python 2.7.3+/3.1.2+, if python is not owned by current user, virtualenv is required

Python > 3 does not seem to be supported as of now.

Thank you for your help & an excellent code-base. I hope to submit a few more PR's in future.

@navneeth I'm sorry for this. Curve is designed to be Python 2/3 compatible and developed in Python 2.7.3, Python 2.7.15 and python 3.1.2, but the compatibility testing of latest version seems not insufficient, eg. request lib, click lib ...
