list index out of range when running function_extractor.py #12

Closed Samfisheryu closed 1 year ago

Samfisheryu commented 1 year ago

after I successfully ran the extraction_runner.py, I got func.out as following (There is only one function because I pick connection_table_lookup which only occurs once in Katran) Then I tried to run function_extractor.py It shows error like this Can I get a sense of what is going on with this?

The problem is caused by line 311 function-extractor.py. By uncommenting the print("Prossing", line), we found that the parsing does not stop when there is no line needed to be parsed.

qthuang commented 1 year ago

In the corresponding func.out, there is no line after "reals,/home/ubuntu/opened/code_annotation/Katran.commented_OPENED_katran_balancer_kern.c, 199, 0"

Also, when extracting some functions, the func.out sometimes have the line

DUPLICATE MAP DEFNS

{#map_name,file_locations } Which also causes IndesError when parsing.

@qthuang This should be fixed...please pull latest code and let us know if it works?
