0.1.2 "no deps" windows package (w/ py.exe) fails with SymPy 0.7.6

[cbm755]

py.exe has been working great for me with SymPy 0.7.5. But now it fails using the new
SymPy 0.7.6. See error below.

1. Strangely, at least one other person has it working! They run
   Windows 8. I'm not sure what Windows I'm using, some sort of terminal
   server, 7 maybe? I've tested with py.exe 2.7.8.9 and 2.7.8.6.
2. @asmeurer (lead SymPy dev) says:

Hmm, I think py2exe changes some behavior of the interpreter. I've
seen some issues on StackOverflow in the past where it couldn't
compile SymPy, for instance. In this case, it looks like it sets
doc on a method to be None instead of the docstring. This really
looks like a bug in py.exe or py2exe.

3. [update] bug confirmed on Windows XP and Windows 7 by two different
   people. Windows 8 doesn't seem to have it.
4. I'll attach a png someone sent me of it working on Windows 8. The
   NameError stuff is just user input errors; it works fine. Below is
   what I get.

[maprieto]

Maybe it's helpful for this issue (or not)

but something unusual happens in "simplify" with py.exe and sympy 0.7.5

[cbm755]

Thanks @maprieto. That does look like same issue.

• Can you also reproduce the same problem with fourier_transform?
• What version of Windows is this?

thanks.

[cbm755]

Wait, @maprieto, did you say you see this on 0.7.5? Not 0.7.6?

[maprieto]

fourier_transform works fine with py.exe and sympy 0.7.5 in my octsympy installation (octsympy-windows-oldsympy-0.1.2.zip under Windows XP, version 2003, service pack 3)

[cbm755]

Hmm, so I can reproduce this error on 0.7.6 (which is consistent with my original bug).

But on 0.7.5, solve works correctly (as in my original bug).

This is on Windows 7 remote server.

@maprieto: what do you see?

[cbm755]

[maprieto]

I've been misspelling the sympy version. Confirmed both commands work in sympy 0.7.5 and py.exe, but that isn't right for sympy 0.7.6

[cbm755]

Good, that is consistent with my original bug. Thanks for double-checking.

[manthey]

The problem with py.exe is that when I created it, I stripped the doc strings from the modules to make it smaller. I didn't realize that it functionally was stripping the doc strings from all import forever more. I've posted a new version of py.exe.

[asmeurer]

Could you make it replace the docstrings with the empty string instead of None?

[cbm755]

@asmeurer's suggestion sounds reasonable. Anyway, I'm going to close this as both sympy and octsympy work with @manthey's new 2.7.9.10 release.

Thank you @manthey.
