Bug 1464538 [wpt PR 11173] - [testdriver] Enable manual interaction, a=testonly Automatic update from web-platform-tests [testdriver] Enable manual interaction (#11173) The testdriver.js utility allows tests which require user input to be fully automated. It requires that the browser be under the control of a WebDriver server in order to do this. In test maintenance contexts, this requirement can slow development because a new browsing session must be created for each trial, and debugging tools such as the developer's console cannot be used. This requirement also limits the tests' value to a larger audience when published online. Visitors to sites like w3c-test.org are interested in observing test results experimentally, but although they may be capable of providing the expected input, the hard requirement on WebDriver will cause tests to fail unconditionally. Extend the framework to accept traditional human input if the test is being run without the WebDriver technology. This allows test authors to debug tests and other interested parties to verify results in browsers of their choosing. It does not interfere with fully-automated test execution. -- wpt-commits: bfd9504d321d35ebfbbe56ab6c7f5c0642495719 wpt-pr: 11173

# This script processes NSS .def files according to the rules defined in
# a comment at the top of each one. The files are used to define the
# exports from NSS shared libraries, with -DEFFILE on Windows, a linker
# script on Linux, or with -exported_symbols_list on OS X.
#
# The NSS build system processes them using a series of sed replacements,
# but the Mozilla build system is already running a Python script to generate
# the file so it's simpler to just do the replacement in Python.
#
# One difference between the NSS build system and Mozilla's is that
# Mozilla's supports building on Linux for Windows using MinGW. MinGW
# expects all lines containing ;+ removed and all ;- tokens removed.
