The BaseHTTPServer, SimpleHTTPServer and CGIHTTPServer has been merged into
http.server in python 3. All of them has been merged as util.httpserver to use
in both python 2 and 3. This patch adds a regex to check-code to warn against
the use of BaseHTTPServer. Moreover this patch also includes updates to lower
part of test-check-py3-compat.t which used to remain unchanged.
The httplib library is renamed to http.client in python 3. So the
import is conditionalized and a test is added in check-code to warn
to use util.httplib
The cPickle is renamed to _pickle in python3 and this C extension is available
in pickle which was not included in earlier versions. So imports are conditionalized
to import cPickle in py2 and pickle in py3. Moreover the use of pickle in py2 is
switched to cPickle as the C extension is faster. The hack is added in util.py and
the modules import util.pickle
python3 url.request and url.error are mapped as util.urlreq/util.urlerr
python2 equivalents from urllib/urllib2 are mapped according to the py3
hierarchy
While the pycompat module will actually handle divergence, please
access these properties from the util module:
util.queue = Queue.Queue / queue.Queue
util.empty = Queue.Empty / queue.Empty
