Bug 127128 – Inspector scripts are not compatible with Python v3

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Marcel Tiede]

Trying to build the current unstable release 2.3.4 under Archlinux fails. Archlinux is using python3 as "/usr/bin/python".

---
File "./Source/JavaScriptCore/inspector/scripts/jsmin.py", line 33, in <module>
    from StringIO import StringIO
ImportError: No module named 'StringIO'
---

As I'm not a python developer I tried fixing this by simply loading the python3 Module io for StringIO, what revealed the next error:

---
 File "./Source/JavaScriptCore/inspector/scripts/generate-combined-inspector-json.py", line 32
    print "usage: %s [json files or directory of json files ...]" % os.path.basename(sys.argv[0])
                                                                ^
SyntaxError: invalid syntax
---

Using parentheses for all print commands in the file "generate-combined-inspector-json.py" fixed the compilation issue.

Maybe add a Python3 comment here so that we know to remove it in the future?
