Gina Häußge 44109f9d8f Automatically cancel running slicing jobs targeting the same output file if a new slicing request is received 
This way there won't be two concurrent jobs trying to slice to the same file, which would practically render the cpu cycles from any slicing jobs than the final one wasted. Also adds a new event "SlicingCancelled" that will be sent in these cases.

.. http:get:: /api/files/(string:location)
Retrieve information regarding the files currently available on the selected `location` and -- if targeting
the ``local`` location -- regarding the disk space still available locally in the system.
Returns a :ref:`Retrieve response <sec-api-fileops-datamodel-retrieveresponse>`.

:param location: The origin location from which to retrieve the files. Currently only ``local`` and ``sdcard`` are
supported, with ``local`` referring to files stored in OctoPrint's ``uploads`` folder and ``sdcard``
referring to files stored on the printer's SD card (if available).
:statuscode 200: No error

.. _sec-api-fileops-uploadfile:
Upload file
===========
.. http:post:: /api/files/(string:location)
Upload a file to the selected `location`.
Other than most of the other requests on OctoPrint's API which are expected as JSON, this request is expected as
``Content-Type: multipart/form-data`` due to the included file upload.
Returns a :http:statuscode:`201` response with a ``Location`` header set to the management URL of the uploaded
file and an :ref:`Upload Response <sec-api-fileops-datamodel-uploadresponse>` as the body upon successful completion.
**Example**

:param location: The target location to which to upload the file. Currently only ``local`` and ``sdcard`` are supported
here, with ``local`` referring to OctoPrint's ``uploads`` folder and ``sdcard`` referring to
the printer's SD card. If an upload targets the SD card, it will also be stored locally first.
:form file: The file to upload, including a valid ``filename``.
:form select: Whether to select the file directly after upload (``true``) or not (``false``). Optional, defaults
to ``false``.
:form print: Whether to start printing the file directly after upload (``true``) or not (``false``). If set, `select`
is implicitely ``true`` as well. Optional, defaults to ``false``.
:statuscode 201: No error
:statuscode 400: If no `file` is included in the request, or the request is otherwise invalid.
:statuscode 404: If `location` is neither ``local`` nor ``sdcard`` or trying to upload to SD card and SD card support
is disabled
:statuscode 409: If the upload of the file would override the file that is currently being printed or if an upload
to SD card was requested and the printer is either not operational or currently busy with a print job.
:statuscode 415: If the file is neither a ``gcode`` nor an ``stl`` file (or it is an ``stl`` file but slicing support
is disabled)
:statuscode 500: If the upload failed internally
.. _sec-api-fileops-retrievefileinfo:
Retrieve a specific file's information
======================================
.. http:get:: /api/files/(string:location)/(path:filename)
Retrieves the selected file's information.
If the file is unknown, a :http:statuscode:`404` is returned.
On success, a :http:statuscode:`200` is returned, with a :ref:`file information item <sec-api-datamodel-files-file>`
as the response body.
**Example**
.. sourcecode:: http

requested file was not found
.. _sec-api-fileops-filecommand:
Issue a file command
====================
.. http:post:: /api/files/(string:target)/(path:filename)
Issue a file command to an existing file. Currently supported commands are:
select
Selects a file for printing. Additional parameters are:
* ``print``: Optional, if set to ``true`` the file will start printing directly after selection. If the printer
is not operational when this parameter is present and set to ``true``, the request will fail with a response
of ``409 Conflict``.
slice
Slices an STL file into GCODE. Note that this is an asynchronous operation that will take place in the background
after the response has been sent back to the client. Additional parameters are:
* ``slicer``: The slicing engine to use, defaults to ``cura`` if not set, which is also the only supported slicer right now.
* ``gcode``: Name of the GCODE file to generated, in the same location as the STL file. Defaults to the STL file name
with extension ``.gco`` if not set.
* ``profile``: Name of the slicing profile to use, if not set the default slicing profile of the slicer will be used.
* ``profile.*``: Override parameters, the ``profile.`` prefix will be stripped and the matching profile key will
be overridden with the supplied value. Use this if you want to specify things that change often like a different
temperature, filament diameter or infill percentage. Profile keys are slicer specific.
If consecutive slicing calls are made targeting the same GCODE filename (that also holds true if the default is used),
the slicing job already running in the background will be cancelled before the new one is started.
Upon success, a status code of :http:statuscode:`204` and an empty body is returned, unless specified otherwise.
**Example Select Request**

.. _sec-api-fileops-delete:
Delete file
===========
