Python 3 compatibility
It would be lovely if this library was compatible with Python 3.
How to introduce a variable in insert_before?
Trying to log time taken by a method. So want to store the time.time() in a variable in insert_before() and print the time taken in the insert_after () as follows -
MY_BEFORE_CODE = '__t1 = time.time(); print ("PERF LOG -START-'+ meth_decl.method_name +'", t1)'
MY_AFTER_CODE = 'print ("PERF LOG -END-'+ meth_decl.method_name +'", time.time() - t1)'
rewriter.insert_before(MY_BEFORE_CODE)
rewriter.insert_after(MY_AFTER_CODE)
getting following error -
SystemError: no locals found when storing '__t1'
Any pointers?
How can I instrument if statements inside a function?
I want to instrument every if function encountered inside a function. For example if my code hits
if x > 2:
I want to record/ print "x > 2" to the console.
Can equip help me out in this regard?
Global lambda expression affect parenting
Global lambda expressions are confusing the parenting heuristic.
import foo
A = lambda x, y: x + y
def foobar():
print A(2, 3)The above code currently produce the following decl:
-> Module
-> Method <lambda>
-> Method foobar
Dominators code throws Key/Index Errors
Hey Romain, great tool you have here, I see you must have ran into the same problems I'm running into, you wrapped it with a try: .. except Exception: :)
https://github.com/neuroo/equip/blob/master/equip/analysis/graph/dominators.py#L61
Do you have any ideas how we should fix this? I can give you a specific test-case but it's not hard to trigger it, it's caused by a JUMP_ABSOLUTE being followed by a RETURN_VALUE and nothing jumping to the JUMP_ABSOLUTE.
115(1322) LOAD_GLOBAL(116) ('something')
115(1325) LOAD_CONST(100) ('/hey/foo.html')
115(1328) CALL_FUNCTION(131) (1)
115(1331) RETURN_VALUE( 83)
115(1332) JUMP_ABSOLUTE(113) (1797) -------------> (1797)
You can't really fix it via
if b not in doms or doms[b] != new_idom:
if new_idom not in post_order_number:
logger.debug("WELL WELL WELL new_idom is %s", new_idom)
else:
doms[b] = new_idom
changed = Truebecause then you run into problems in __build_df.
