A regex greediness problem

description

This regex should only match the middle paragraph.

/Exception in thread.*?TimeoutError: QueuePool limit of size 40 overflow 10 reached, connection timed out, timeout 30/m

Rubular (and testing in perl too) show I am wrong.  it matches paragraph 1 and 2.  The ? should make it non-greedy

input data

TimeoutError: QueuePool limit of size 40 overflow 10 reached, connection timed out, timeout 30

Exception in thread 1310229058:
Traceback (most recent call last):
TimeoutError: QueuePool limit of size 40 overflow 10 reached, connection timed out, timeout 30

Exception in thread 1310249350:
TimeoutError: QueuePool limit of size 40 overflow 10 reached, connection timed out, timeout 30

/Exception in thread[^\n\r]\n\r?TimeoutError: QueuePool limit of size \d overflow \d* reached, connection timed out, timeout \d+/m

.*? is not being greedy... it is saying match anything up to TimeoutError which is true for both 2 and 3 but not the first line. w/o the ? it will catch both paragraphs as one full match.

It's grabbing both, at once, with the ?

Two only match the middle paragraph

/Exception in thread(?:[^\n\r]\n\r?){2}TimeoutError: QueuePool limit of size \d overflow \d* reached, connection timed out, timeout \d+/m

If there are more than those 3 lines it would not match.

Never mind, rubular is showing successive matches. DOH
