Jython25BackwardsIncompatibilities

Legacy Wiki Page

This page was migrated from the old MoinMoin-based wiki. Information may be outdated or no longer applicable. For current documentation, see python.org.

* You can no longer do PyFile{.backtick}(inputStream) directly from Jython code. This is because a PyFile{.backtick} that gets an InputStream{.backtick} [INSERT REAL REASON], so that the recommended approach is to replace code like:

from java.io import FileInputStream
from org.python.core import PyFile
fis = FileInputStream("error.txt")
pyf = PyFile(fis)

with code like:

from java.io import FileInputStream
from org.python.core.util import FileUtil
fis = FileInputStream("error.txt")
pyf = FileUtil.wrap(fis)

* types.ArrayType has been removed as CPython never had it. Use array.ArrayTypes instead (which is available in both 2.2 and 2.5)

* The pre and xreadlines modules have been removed
