I have a small server-side script that is wroking fine when a single user is logged in, but when multiple users access the system I m getting exceptions from the MySQL connection as shown below: Exception in thread Thread-1: Traceback (most recent call last): File "/usr/lib/python2.6/[login to view URL]", line 532, in __bootstrap_inner [login to view URL]() File "[login to view URL]", line 73, in run process_message([login to view URL], [login to view URL], [login to view URL], [login to view URL], data_in) File "[login to view URL]", line 149, in process_message rc = process_decrypted(node, skts, cfg, enc, message) File "[login to view URL]", line 279, in process_decrypted return reply File "/usr/local/lib/python2.6/dist-packages/pony/orm/[login to view URL]", line 354, in __exit__ if exc_type is None: commit() # exc_value can be None in Python 2.6 even if exc_type is not None File "<string>", line 2, in commit File "/usr/local/lib/python2.6/dist-packages/pony/[login to view URL]", line 96, in cut_traceback return func(*args, **kwargs) File "/usr/local/lib/python2.6/dist-packages/pony/orm/[login to view URL]", line 269, in commit reraise(CommitException, exceptions) File "/usr/local/lib/python2.6/dist-packages/pony/orm/[login to view URL]", line 263, in commit try: [login to view URL]() File "/usr/local/lib/python2.6/dist-packages/pony/orm/[login to view URL]", line 3657, in commit [login to view URL]() File "/usr/local/lib/python2.6/dist-packages/pony/orm/[login to view URL]", line 3720, in save obj._save_() File "/usr/local/lib/python2.6/dist-packages/pony/orm/[login to view URL]", line 3591, in _save_ elif status == 'updated': obj._save_updated_() File "/usr/local/lib/python2.6/dist-packages/pony/orm/[login to view URL]", line 3522, in _save_updated_ throw(UnrepeatableReadError, 'Object %s was updated outside of current transaction' % safe_repr(obj)) File "/usr/local/lib/python2.6/dist-packages/pony/[login to view URL]", line 123, in throw raise exc CommitException: Object node[2] was updated outside of current transaction I am looking for someone who can help debug this. Debugging would need to occur "in-situ" and login details to the server will be provided.

I understand what the problem is and have a good idea how it can be fixed. Only concern is how will my fix affect the existing code and how much of it will/might need to be rewritten. Updated my bid for debugging and fixing a 350 lines script that works independently. I have no intention to change pony unless I found its not thread safe. either case my bid is final

Greetings, I am pretty experienced with Python programming, especially in a data-intensive and web-oriented setting. The error message looks like a data inconsistency problem caused by concurrent write. I think I should be able to fix it in a matter of hours. To accommodate unforeseeable uncertainties, I set the bidding time frame to 3 days. That's more than enough to solve this problem. By the way, according to the error message, the effective Python version is 2.6, not 2.7 Feel free to send me private messages to discuss.

The probles is that you leave an open conection during the register procces, then, when another user tries to login, it finds an existing connection in the same instance, and that's what generates that error. Btw, I'd like to see the code.
