Clean BG processes created by %%script on kernel exit
* uses less forceful shutdown of kernels in the notebook, allowing atexit machinery to fire
* enables daemon BackgroundJobs
* cleanup %%script --bg subprocesses at shutdown
minor notebook startup/notebook-dir adjustments
* change inaccurate / distressing "Overwriting profile..." log message
* `ipython notebook path` results in setting notebook-dir if it's a dir,
rather than unconditionally setting file-to-run
* file-to-run overrides no-browser
* kernels start in the notebook dir, rather than the Server's cwd
* notebook dir is validated, and created if it doesn't exist (only if parent exists, like ~all other such things)
closes#1985closes#1980
only one line of actual code is changed.
these names have been removed from the next libzmq release,
and will presumably be removed from pyzmq someday.
Heartbeats start immediately, causing false heart failures on slow systems that can take a while to start kernel subprocesses.
Also adds a 'flush' to the heartbeat callback (just like in IPython.parallel), to protect against server load being detected as heart failures.
Most int traits are now Integers
Integer differs from Long only in that small `long`s are cast to `int`, rather than
all `int`s being cast to `long`:
Integer(4L) => 4
Long(4) => 4L
closes gh-942, closes gh-996.
Rebased to avoid recursive merge for just one commit.
This is separate from previous, because it is more likely to be rejected.
It requires the the Session objects in Handlers get a reference all the way back up to the IPython App that started the environment.
These messages are not returned to the browser, but are printed
to the server logs and will help the code readability.
I have also used a more specific code in some cases.
* Favicon.ico is served.
* Test suit now passes.
* Help links work for for me.
* Other changes made to address inline comments.
* The printing of long lines is an extremely subtle issue and I will open an issue for it.
* zmqws.py is completely gone so the naked print is not an issue.
* ipython-notebook removed from scripts.
* Updated copyright and authors of files.
* Fixed missing docstrings in IPython.nbformat.
* Full kernel heartbeating is working.
* Connections between the notebook and server and now created
a new each time there is a WebSocket connection. Each channel is
also handled separately. This dramatically simplifies the
server code and makes for a more scalable system.
* Old routers were not being shutdown and removed.
* We were incorrectly associating the new kernel with the notebook
(we were using the *old* kernel_id for this).
* General clean ups in the kernel manager.
* The KernelManager now manages multiple kernels with a uniform
API.
* The SessionManager now manages the full set of channels+streams
and the IPython.zmq.session.Session object for a single kernel.
Previously, each client (browser window) would open its own set
of ZMQ sockets to a kernel. Now one master set of connections
to the kernel is created and all clients share those connections.
In some ways, this simplifies the URL design.
I have also made kernel_ids server-side created.
