commit 5178fc299d361c9ab57002e619e40b05061f5a7d Author: Arturo Filastò <arturo(a)filasto.net> Date: Sat May 28 19:05:42 2016 +0200 Feature/web connectivity (#63) * Add web connectivity test helper * Forward test helper addresses to the host machine * Align the request headers used by the web_connectivity test helper to those of the probe * Add monkey patch for bug in twisted RedirectAgent: https://twistedmatrix.com/trac/ticket/8265 * Add monkey patch for HTTPClientParser.statusReceived * Use TrueHeaders in control request * Add support for specifying endpoints in web_connectivity test helper * Add endpoint for checking the status of the WebConnectivity test helper * Add support for parsing test-helpers-alternate * Fix key for web_connectivity test in example configuration file * Implement on-disk web_connectivity cache * Add support for Gzip content decoding * Also record CNAME resolution. * Rename ips to addrs * Add support for retries in the http_request * Add support for extracting title * Encode the responses as well when debug mode * Handle partial downloads * Ignore errors when encoding headers * Cast title to unicode and ignore errors * Improvements based on feedback and comments by @bassosimone * Move twisted related patches into txextra module * Add support for returning the responses based on a key sent by the client. * Inherit from OONIBHandler so we can get the error message format * Stylistic improvements * Set defaults in a way that oonib.conf can start from the example * Avoid doing join on nonetype * Address comments by @bassosimone * Properly set the body also when we get a partial body downloaded * Move more code into shared oonib.common module * Fully sync the common module with ooni-probe (pulling in also other shared functionality so the Agents match entirely) * Fix location of comment for the patched HTTPClient * Add unittests and integration tests for web_connectivity --- Vagrantfile | 25 +++ oonib.conf.example | 18 +- oonib/bouncer/handlers.py | 14 +- oonib/common/__init__.py | 10 ++ oonib/common/http_utils.py | 54 ++++++ oonib/common/tcp_utils.py | 10 ++ oonib/common/txextra.py | 202 +++++++++++++++++++++ oonib/oonibackend.py | 29 ++- oonib/test/test_web_connectivity.py | 71 ++++++++ oonib/testhelpers/http_helpers.py | 344 +++++++++++++++++++++++++++++++++++- 10 files changed, 758 insertions(+), 19 deletions(-) diff --git a/Vagrantfile b/Vagrantfile index b71e4e7..7aa5f71 100644 --- a/Vagrantfile +++ b/Vagrantfile @@ -4,6 +4,31 @@ Vagrant.configure("2") do |config| config.vm.box = "precise32" config.vm.box_url = "http://files.vagrantup.com/precise32.box" + + # Create a forwarded port mapping which allows access to a specific port + # within the machine from a port on the host machine.
