This made the notebook server artificially and unnecessarily brittle to tunneling, and non-local hostname resolution. The ws_url is now defined based on the Origin of the request. This allows tunneled hosts and ports to preserve connections, as the ws_url always matches the one in use by the client.
Implemented as a property, to facilitate future cases where it might behave differently.
Add directory for startup files, enabling users to add local configuration more simply without having to know how the config system works much at all.
Now, `profile/startup` dir is checked for files, and they are run prior to explicit exec_code and exec_files.
A short README is added to the dir explaining how they work, and a short paragraph is added to the docs, in both the interactive tutorial and config overview.
Monkeypatch Tornado 2.1.{0, 1} so it works with Google Chrome 16.
This uses a fix from Tornado itself that's just a protocol number check, no actual protocol handling code is necessary.
The notebook now supports a `--read-only` flag, which allows users to view all notebooks being served but not to edit them or execute any code. These actions are not allowed and the buttons, shortcuts, etc. are removed, but the requests will raise authentication errors if they manage to send the events anyway. Save/print functions remain available.
This flag can be used in two modes:
1. When running an unauthenticated server, one can run a *second* read-only server in the same directory on a public IP address. This will let users connect to the read-only view without having to worry about configuring passwords and certificates for the execution server.
2. When running a server configured with authentication (and hopefully an SSL certificate), starting it with `--read-only` allows unauthenticated users read-only access to notebooks. This means that the same server on a single port can be both used by authenticated users for execution and by the public for viewing the available notebooks.
Show invalid config message on TraitErrors during initialization.
implemented via `@catch_config` decorator
Now, the event that was triggered by invalid app config (see `--log-level 5`) is triggered by bad config at any point during initialization.
This *will* catch TraitError-raising bugs in IPython itself, but only during initialization.
Also, deregister crash handler on use to avoid it being triggered recursively/repeatedly.
If a user has Chrome set as their default browser (system-wide or via
the `BROWSER` environment variable), opening the notebook hangs
because the chrome call doesn't return immediately. This solves the
issue by opening the browser in a thread.
Note that there remains an issue where killing the notebook will kill
Chrome if the Chrome session was started by us. I haven't found a way
to work around that despite attempts by making the webbrowser.open()
call in a subprocess.
When using a password, read-only mode allows unauthenticated users
read-only access to notebooks. Editing, execution, etc. are not
allowed in read-only mode, but save/print functions are available.
No kernels are started until an authenticated user opens a notebook.

The History will always appear empty, so history magics, etc. don't do anything. Readline history for a single session works fine.
Test suite should now pass without sqlite
Adding clear_output to kernel and HTML notebook.
This enables the clearing of output during the execution of a cell. It can be used for simple forms of animation in the notebook.
All buttons, show/hide clickable areas, etc. should have some tooltip describing
what they do. There are jQuery plugins for enhanced tooltips, but this gets
the lightest version working.
