MemoryError due to AST

[Leonel Câmara]

So I made this change:

https://github.com/web2py/web2py/pull/2145/files

Which basically makes web2py use ast instead of a regex to find functions, this solves the problem with type annotations and other things that the regex didn't expect when searching for functions, but since I started using it I have gotten quite a lot of MemoryError in my application such as this:

    parsed = ast.parse(data)
  File "/usr/lib/python2.7/ast.py", line 37, in parse
    return compile(source, filename, mode, PyCF_ONLY_AST)

In fact since upgrading to 2.18.4 I've been getting memory errors in a lot of other places as well, namely in DAL stuff. I'm not sure if they're related, if they're caused by this ast change or due to changes in the DAL or custom importer. 

 

Anyone having the same problems?
