Eunsoo Park	20c2c66857	Attempt to re-establish websocket connection to Gateway ... When notebook (with `--gateway-url` option) lost the connection to Gateway, notebook didn't connect to Gateway again although the websocket connection from the client was still alive. This change recovers the connection to Gateway to prevent this anomaly. Signed-off-by: Eunsoo Park <esevan.park@gmail.com>	7 years ago
Kevin Bates	7e50cdc856	Remove verbose debug statement in gateway mode ... I removed the mirroring 'Receiving' debug statement previously and didn't realize there's a 'Sending' statement. This change removes that statement. This should be part of the 6.0 release, just not signficant enough to warrant include in rc1.	7 years ago
Kevin Bates	f6e3c23089	Missing yield statement on WebSocketChannelsHandler (#4724) ... We were missing a yield statement in the deferral of `get()` to the superclass. This issue was occurring only when Tornado 6+ was deployed. Also removed a debug message producing way too much information.	7 years ago

Kevin Bates	191dc333f6	Modify/add various timeout values ... The connect and request timeout defaults have been updated from 20 to 60 seconds and a default value of 40 has been added for KERNEL_LAUNCH_TIMEOUT. The code ensures that KERNEL_LAUNCH_TIMEOUT is in the env and that the value of the request timeout is at least 2 greather than KERNEL_LAUNCH_TIMEOUT. This PR is port of the NB2KG PRs 35 and 38.	7 years ago

Kevin Bates	acba19033b	Minimize handlers and manager methods ... Eliminated the Kernel and Kernelspec handlers. The Websocket (ZMQ) channels handler still remains. This required turning a few methods into coroutines in the Notebook server. Renamed the Gateway config object to GatewayClient in case we want to extend NB server (probably jupyter_server at that point) with Gateway server functionality - so an NB server could be a Gateway client or a server depending on launch settings. Add code to _replace_ the channels handler rather than rely on position within the handlers lists. Updated mock-gateway to return the appropriate form of results. Updated the session manager tests to use a sync ioloop to call the now async manager methods.	7 years ago
Kevin Bates	f74ef2f691	Move environment variables to SingletonConfigurable ... Created a singleton class `Gateway` to store all configuration options for a Gateway. This class also holds some help methods to make it easier to use the options and determine if the gateway option is enabled. Updated the NotebookTestBase class to allow for subclasses to infuence the patched environment as well as command line options via argv. Added a test to ensure various gateway configuration items can be set via the environment or command-line.	7 years ago
Kevin Bates	060a2b9aea	Embed NB2KG into Notebook server ... This change alleviates a significant pain-point for consumers of Jupyter Kernel and Enterprise Gateway projects by embedding the few classes defined in the NB2KG server extension directly into the Notebook server. All code resides in a separate gateway directory and the 'extension' is enabled via a new configuration option `--gateway-url`. Renamed classes from those used in standard NB2KG code so that Notebook servers using the existing NB2KG extension will still work. Added test_gateway.py to exercise overridden methods. It does this by mocking the call that issues requests to the gateway server. Updated the _Running a notebook server_ topic to include a description of this feature.	7 years ago
