Alexis Daboville added the comment: I don't think it can be "fixed" with sys.setrecursionlimit for a few reasons:
* I think the issue arises when the AST is built. Otherwise if we put code before the if it would execute. But that's not the case (try putting a print('hello') before the if and it won't print anything). - This also means that you cannot directly call sys.setrecursionlimit in the file with the elifs. - Though we can set recursion limit using a second file which will then import the elifs file: I tried with different limits and CPython still crash in the same way (and always with the same number of elifs, roughly, because I didn't binary search for the exact amount of elifs). - sys.setrecursionlimit controls the stack size of the running Python program, while here we break C stack directly before running Python bytecode. * When recursion limit is hit, an exception is raised, there's no segfault: >>> def f(): ... f() ... >>> f() # plenty of omitted lines RuntimeError: maximum recursion depth exceeded >>> * Having a RuntimeError raised would be nice, though 'maximum recursion depth exceeded' may not be the best possible error message as from a 'Python user' POV there's no recursion here. --- A possible solution would be, I guess, to store elifs as excepts are stored. Instead of storing elifs recursively, the else part would just contain a list of if nodes (and if there is a else, well just store an if True node). Though I don't know how difficult it would be to implement that, or if it's likely to break a lot of things which relies on ifs/elifs to be stored that way. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue16527> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
