hghave: add "py3k" feature to check whether test runs with Python 3.x This patch adds "py3k" feature to check whether test runs with Python 3.x. This check is needed for portability of test code: for example, in the default, modules are imported relatively first with python 2.x, but imported absolutely with Python 3.x. [ original upstream message ]

hghave: add "absimport" feature to check "absolute_import" in __future__ This patch adds "absimport" feature to check whether "absolute_import" exists in __future__, which means supporting module loading by absolute name. This check is needed for portability of test code using "absolute_import", because Python earlier than 2.5 doesn't support it. [ original upstream message ]

run-tests: place the .t shell script next to $TESTTMP and with a useful name --keep can thus keep it around - very convenient for debugging. [ original upstream message ]

get-with-headers: don't block indefinitely if the server had an internal error If the server had an internal error and returned 500, there's nothing to read, so "response.read()" blocks indefinitely. Only output the response if there's really a response. [ original upstream message ]
