5.2.4 to 5.2.5 syntaxError

Development Installer
1

Hello
I just did :

  • installation with UnifiedInstaler of 5.2.4 py3.7
  • changed the version URL to the 5.2.5
    launched ./bin/buildout

Just to let you now : I had the following errors which could be just cosmetic for everything works fine :

Compiling Python files.

    print 'rename %s to %s' % (old_filename, new_filename)
                          ^

The problem, or a variant thereof, is described in buildout troubleshooting. Originally, you would get these SyntaxErrors mostly when Python is seeing skin scripts, which use a syntax that may not always be correct Python.
In this case Python 3 is probably seeing Python 2 code which is included in a package but will only get run on Python 2.

For example it complains here in zodbpickle about a file called pickletools_2.py, but there is also a file pickletools_3.py which is probably the one that gets used on Python 3.

So: in 99.9 percent of the cases this is nothing to worry about, and that seems the case here.
