<h1 id="n:1.">1. Non Session Management API</h1>
|
||||||
|
<p>
|
||||||
|
The Non Session Management API is used by the various components of the Non audio production suite to allow any number of independent programs to be managed together as part of a logical session (i.e. a song). Thus, operations such as loading and saving are synchronized.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
The API comprises a simple Open Sound Control (OSC) based protocol, along with some behavioral guidelines, which can easily be implemented by various applications.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
The Non project contains an program called <tt>nsmd</tt> which is an implementation of the server side of the NSM API. <tt>nsmd</tt> is controlled by the <tt>non-session-manager</tt> GUI. However, the same server-side API can also be implemented by other session managers (such as LADISH), although consistency and robustness will likely suffer if non-NSM compliant clients are allowed to participate in a session. The only dependency for client implementations <tt>liblo</tt> (the OSC library), which several Linux audio applications already link to or plan to link to in the future.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
The aim of this project is to thoroughly define the behavior required of clients. This is an area where other attempts at session management (LASH and JACK-Session) have failed. Often the difficulty with these systems has been not in implementing support for them, but in attempting to interpret the confusing, ambiguous, or ill-conceived API documentation. For these reasons and more all previous attempts at Linux audio session management protocols are considered harmful.

You <b>WILL</b> see some unambiguous and emphatic language in this document. For the good of the user, these rules are meant to be followed and are non-negotiable. If an application does not conform to this specification it should be considered broken. Consistency across applications under session management is very important for a good user experience.
|

<h2 id="n:1.1.">1.1. Client Behavior Under Session Management</h2>
|
||||||
|
<p>
|
||||||
|
Most graphical applications make available to the user a common set of file operations, typically presented under a File or Project menu.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
These are: New, Open, Save, Save As, Close and Quit or Exit.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
The following sub-sections describe how these options should behave when the application is part of an NSM session. These rules only apply when session management is active (that is, after the <tt>announce</tt> handshake described in the <a class=int href="#"></a> section). In order to provide a consistent and predictable user experience, it is critically important for applications to adhere to these guidelines.
|
||||||
|
</p>
|
||||||
|
<h3 id="n:1.1.1.">1.1.1. New</h3>
|
||||||
|
<p>
|
||||||
|
This option may empty/reset the current file or project (possibly after user confirmation). <b>UNDER NO CIRCUMSTANCES</b> should it allow the user to create a new project/file in another location.
|
||||||
|
</p>
|
||||||
|
<h3 id="n:1.1.2.">1.1.2. Open</h3>
|
||||||
|
<p>
|
||||||
|
This option <b>MUST</b> be disabled.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
The application may, however, elect to implement an option called 'Import into Session', creates a copy of a file/project which is then saved at the session path provided by NSM.
|
||||||
|
</p>
|
||||||
|
<h3 id="n:1.1.3.">1.1.3. Save</h3>
|
||||||
|
<p>
|
||||||
|
This option should behave as normal, saving the current file/project as established by the NSM <tt>open</tt> message.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
<b>UNDER NO CIRCUMSTANCES</b> should this option present the user with a choice of where to save the file.
|
||||||
|
</p>
|
||||||
|
<h3 id="n:1.1.4.">1.1.4. Save As</h3>
|
||||||
|
<p>
|
||||||
|
This option <b>MUST</b> be disabled.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
The application may, however, elect to implement an option called 'Export from Session', which creates a copy of the current file/project which is then saved in a user-specified location outside of the session path provided by NSM.
|
||||||
|
</p>
|
||||||
|
<h3 id="n:1.1.5.">1.1.5. Close (as distinguished from Quit or Exit)</h3>
|
||||||
|
<p>
|
||||||
|
This option <b>MUST</b> be disabled unless its meaning is to disconnect the application from session management.
|
||||||
|
</p>
|
||||||
|
<h3 id="n:1.1.6.">1.1.6. Quit or Exit</h3>
|
||||||
|
<p>
|
||||||
|
This option may behave as normal (even possibly asking the user to confirm exiting).
|
||||||
|
</p>
|
||||||
|
<h2 id="n:1.2.">1.2. NSM OSC Protocol</h2>
|
||||||
|
<p>
|
||||||
|
All message parameters are <b>REQUIRED</b>. All messages <b>MUST</b> be sent from the same socket as the <tt>announce</tt> message, using the <tt>lo_send_from</tt> method of liblo or its equivalent, as the server uses the return addresses to distinguish between clients.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
Clients <b>MUST</b> create thier OSC servers using the same protocol (UDP,TCP) as found in <tt>NSM_URL</tt>. liblo is lacking a robust TCP implementation at the time of writing, but in the future it may be useful.
|
||||||
|
</p>
|
||||||
|
<h3 id="n:1.2.1.">1.2.1. Establishing a Connection</h3>
|
||||||
|
<h4 id="n:1.2.1.1.">1.2.1.1. Announce</h4>
|
||||||
|
<p>
|
||||||
|
At launch, the client <b>MUST</b> check the environment for the value of <tt>NSM_URL</tt>. If present, the client <b>MUST</b> send the following message to the provided address as soon as it is ready to respond to the <tt>/nsm/client/open</tt> event:
|
||||||
|
</p>
|
||||||
|
<div class="fig example"><table width=100%><tr><td><pre>
|
||||||
|
/nsm/server/announce s:application_name s:capabilities s:executable_name i:api_version_major i:api_version_minor i:pid
|
||||||
|
</pre></td></tr>
|
||||||
|
</table></div>
|
||||||
|
<p>
|
||||||
|
If <tt>NSM_URL</tt> is undefined, invalid, or unreachable, then the client should proceed assuming that session management is unavailable.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
<tt>api_version_major</tt> and <tt>api_version_minor</tt> must be the two parts of the version number of the NSM API as defined by this document.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
Note that if the application intends to register JACK clients, <tt>application_name</tt> <b>MUST</b> be the same as the name that would normally by passed to <tt>jack_client_open</tt>. For example, Non-Mixer sends "Non-Mixer" as its <tt>application_name</tt>. Applications <b>MUST NOT</b> register their JACK clients until receiving an <tt>open</tt> message; the <tt>open</tt> message will provide a unique client name prefix suitable for passing to JACK. This is probably the most complex requirement of the NSM API, but it isn't difficult to implement, especially if the application simply wishes to delay its initialization process breifly while awaiting the <tt>announce</tt> reply and subsequent <tt>open</tt> message.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
<tt>capabilities</tt> <b>MUST</b> be a string containing a colon separated list of the special capabilities the client possesses. e.g. ":dirty:switch:progress:"

<h3 id="n:1.2.2.">1.2.2. Server to Client Control Messages</h3>
|
||||||
|
<p>
|
||||||
|
Compliant clients <b>MUST</b> accept the client control messages described in this section. All client control messages <b>REQUIRE</b> a response. Responses <b>MUST</b> be delivered back to the sender (NSM) from the same socket used by the client in its <tt>announce</tt> message (by using <tt>lo_send_from</tt>) <b>AFTER</b> the action has been completed or if an error is encountered. The required response is described in the subsection for each message.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
If there is an error and the action cannot be completed, then <tt>error_code</tt> <b>MUST</b> be set to a valid error code (see <a href="#Fig."></a>) and <tt>message</tt> to a string describing the problem (suitable for display to the user).
|
||||||
|
</p>
|
||||||
|
<p>

There is no message for this. Clients will receive the Unix SIGTERM signal and <b>MUST</b> close cleanly <b>IMMEDIATELY</b>, without displaying any kind of dialog to the user and regardless of whether or not unsaved changes would be lost. When a session is closed the application will receive this signal soon after having responded to a <tt>save</tt> message.

|

|
</p>
|
||||||
|
<p>
|
||||||
|
If a project does not exist at the path, then the client <b>MUST</b> immediately create and open a new one at the specified path or, for clients which hold all their state in memory, store the path for later use when responding to the <tt>save</tt> message.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
No file or directory will be created at the specified path by the server. It is up to the client to create what it needs.

</p>
|

<p>
|
||||||

For clients which <b>HAVE NOT</b> specified the <tt>:switch:</tt> capability, the <tt>open</tt> message will only be delivered once, immediately following the <tt>announce</tt> response.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
For clients which <b>HAVE</b> specified the <tt>:switch:</tt> capability, the client <b>MUST</b> immediately switch to the specified project or create a new one if it doesn't exist.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
Clients which are incapable of switching projects or are prone to crashing upon switching <b>MUST NOT</b> include <tt>:switch:</tt> in their capability string.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
If the user the is allowed to run two or more instances of the application simultaneously (that is to say, there is no technical limitation preventing them from doing so, even if it doesn't make sense to the author), then such an application <b>MUST PRE-PEND</b> the provided <tt>client_id</tt> string to any names it registers with common subsystems (e.g. JACK client names). This ensures that multiple instances of the same application can be restored in any order without scrambling the JACK connections or causing other conflicts. The provided <tt>client_id</tt> will be a concatenation of the value of <tt>application_name</tt> sent by the client in its <tt>announce</tt> message and a unique identifier. Therefore, applications which create single JACK clients can use the value of <tt>client_id</tt> directly as their JACK client name. Applications which register multiple JACK clients (e.g. Non-Mixer) <b>MUST PRE-PEND</b> <tt>client_id</tt> value to the client names they register with JACK and the application determined part <b>MUST</b> be unique for that (JACK) client.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
For example, a suitable JACK client name would be:
|
||||||
|
</p>
|
||||||
|
<div class="fig example"><table width=100%><tr><td><pre>
|
||||||
|
$CLIENT_ID/track-1
|
||||||
|
</pre></td></tr>
|
||||||
|
</table></div>
|
||||||
|
<p>
|
||||||
|
Note that this means that the application <b>MUST NOT</b> register with JACK (or any other subsystem requiring unique names) until it receives an <tt>open</tt> message from NSM. Likewise, applications with the <tt>:switch:</tt> capability should close their JACK clients and re-create them with using the new <tt>client_id</tt>. Re-registering is necessary because the JACK API does currently support renaming existing clients, although this is a sorely needed addition.
|
||||||
|
</p>
|
||||||
|
<p>
|
||||||
|
A response is <b>REQUIRED</b> as soon as the open operation has been completed. Ongoing progress may be indicated by sending messages to <tt>/nsm/client/progress</tt>.

<p>
|
||||||
|
If the server publishes the <tt>:server_control:</tt> capability, then clients can also initiate action by the server. For example, a client might implement a 'Save All' option which sends a <tt>/nsm/server/save</tt> message to the server, rather than requiring the user to switch to the session management interface to effect the save.

|
||||||

|
All of the following messages will be responded to back to the sender's address with one of the two following messages:

:: The Non Session Manager Graphical Interface
|
||||||
|
|
||||||
|
/ Non Session Manager
|
||||||
|
< nsm.png
|
||||||
|
|
||||||
|
The Non Session Manager is a graphical interface to the NSM Daemon
|
||||||
|
(nsmd). By default, running the command `non-session-manager` will
|
||||||
|
start both the GUI and an instance of the daemon.
|
||||||
|
|
||||||
|
If a different session root than the default is desired, it may be
|
||||||
|
specified on the command-line as follows:
|
||||||
|
|
||||||
|
> non-session-manager -- --session-root path
|
||||||
|
|
||||||
|
This command will instruct the instance of nsmd that the GUI starts
|
||||||
|
to use `path` as the session root.
|
||||||
|
|
||||||
|
All session data is stored in per-session sub-directories of the
|
||||||
|
/Session Root/.
|
||||||
|
|
||||||
|
::: Session Operations
|
||||||
|
|
||||||
|
:::: Open
|
||||||
|
|
||||||
|
There are two ways to open a session.
|
||||||
|
|
||||||
|
The first is to click the Open button and type in the exact name of
|
||||||
|
an existing session. The second is to click on the desired session
|
||||||
|
name in the session list panel in the left hand half of the
|
||||||
|
interface.
|
||||||
|
|
||||||
|
Either way, opening a session saves the current session and switches
|
||||||
|
to the new one. Clients which are capable of switching projects
|
||||||
|
without restarting are instructed to do so, resulting in very fast
|
||||||
|
session open times when such clients are participating in both
|
||||||
|
sessions.
|
||||||
|
|
||||||
|
Clients cannot be added until a session is open, either by /Open/ or
|
||||||
|
/New/.
|
||||||
|
|
||||||
|
As each client launches, a status bar representing it will be added
|
||||||
|
to the client list in the hand panel of the interface. For clients
|
||||||
|
which are capable of reporting their progress, a progress bar will
|
||||||
|
also become active.
|
||||||
|
|
||||||
|
Only clients supporting the NSM protocol can be told what to open
|
||||||
|
and when to save. Clients not supporting NSM may still be added to
|
||||||
|
the session, but their behavior is undefined other than that NSM can
|
||||||
|
invoke and kill them.
|
||||||
|
|
||||||
|
:::: Close
|
||||||
|
|
||||||
|
This option saves and closes the current session. All clients
|
||||||
|
participating in the session are told to quit. Note that, as
|
||||||
|
mentioned in the preceding section, in NSM it is not necessary to
|
||||||
|
close one session before opening another.
|
||||||
|
|
||||||
|
:::: Abort
|
||||||
|
|
||||||
|
This option closes the current session *without saving*.
|
||||||
|
|
||||||
|
:::: Save
|
||||||
|
|
||||||
|
This option saves the current session, instructing clients
|
||||||
|
supporting the NSM protocol to save.
|
||||||
|
|
||||||
|
:::: New
|
||||||
|
|
||||||
|
This option saves the current session (if one is open) and creates a
|
||||||
|
new one. The user is prompted for a session name. Session names are
|
||||||
|
paths under the defined /Session Root/. A session name may include
|
||||||
|
any number of hierarchical elements, which need not be pre-existing.
|
||||||
|
|
||||||
|
For example, one might name a session as follows:
|
||||||
|
|
||||||
|
> Albums/Magnum Opus/The Best Song Ever Produced
|
||||||
|
|
||||||
|
When inspecting /Session Root/ in a file manager, the above
|
||||||
|
represents exactly the path you would see.
|
||||||
|
|
||||||
|
Renaming a session is not currently supported, but one may simply
|
||||||
|
move directories around under /Session Root/ and NSM will detect the
|
||||||
|
new layout upon the next invocation. The session name is not stored
|
||||||
|
anywhere except in its path.
|
||||||
|
|
||||||
|
Advanced users may choose to use symbolic links to organize their
|
||||||
|
sessions. For example, one could store all their songs under
|
||||||
|
'Songs\/' and create an 'Albums/\' directory structure which uses
|
||||||
|
symlinks to point at the songs stored.
|
||||||
|
|
||||||
|
:::: Duplicate
|
||||||
|
|
||||||
|
Templates are supported in by the Non Session Manager via
|
||||||
|
duplication. Clicking on the /Duplicate/ button with a session open
|
||||||
|
will prompt the user for a new session name. The daemon will then
|
||||||
|
perform a recursive file copy of the session and open the copy.
|
||||||
|
|
||||||
|
Obviously, this should be avoided for sessions containing audio
|
||||||
|
data, as the copy would be very time consuming.
|
||||||
|
|
||||||
|
To create a template in the first place, simply use /New/ to start a
|
||||||
|
new session (preferably with a name beginning with Template\/), add
|
||||||
|
the desired clients to it, and configure them (e.g. add plugins,
|
||||||
|
make JACK connections, etc.)
|
||||||
|
|
||||||
|
Now, any time you want to start a session from that template, simply
|
||||||
|
switch to the template session and click /Duplicate/ to create a new
|
||||||
|
session based on it.
|
||||||
|
|
||||||
|
:::: Add Client
|
||||||
|
|
||||||
|
This option will prompt the user for the executable name of the
|
||||||
|
client to be added to the session. It is not necessary to type the
|
||||||
|
full path (the PATH environment variable will be searched to find
|
||||||
|
the executable).
|
||||||
|
|
||||||
|
::: Removing a Client From a Session
|
||||||
|
|
||||||
|
If a client dies unexpectedly or is closed by the user (e.g. by
|
||||||
|
closing its main window), Non Session Manager will detect this and
|
||||||
|
two buttons will appear on that Client's status bar. One button, the
|
||||||
|
arrow, causes the client to be restarted, and to reopen its project
|
||||||
|
file where it left off. The /X/ button causes the client to be
|
||||||
|
permanently removed from the session.
|

|
:: The NSM Daemon
|
||||||
|
|
||||||
|
The NSM Daemon (nsmd) is launched automatically by the Non Session
|
||||||
|
Manager interface whenever one is not found to be already running at
|
||||||
|
the URL specified in the environment
|
||||||
|
|
||||||
|
Users who are not attempting setup advanced modes like shared
|
||||||
|
sessions between machines will not normally need to even know that
|
||||||
|
`nsmd` is running.
|
||||||
|
|
||||||
|
But for those advanced users, here are the command-line options for launching
|
||||||
|
nsmd separately from the GUI.
|
||||||
|
|
||||||
|
> nsmd [--session-root path] [--osc-port port] [--detach]
|
||||||
|
|
||||||
|
The `--session-root` option allows one to override default /Session
|
||||||
|
Root/ is "$HOME\/NSM Sessions" (this option can also be passed to the
|
||||||
|
GUI, which will hand it over to the daemon).
|
||||||
|
|
||||||
|
`--osc-port` instructs the daemon to bind to a specific UDP port
|
||||||
|
number instead of selecting an available port automatically.
|
||||||
|
|
||||||
|
`--detach` instructs the daemon to close its standard input and
|
||||||
|
output and go completely into the background. This is useful for
|
||||||
|
starting the daemon remotely with `rsh`.
|
||||||
|
|
||||||
|
When nsmd starts, it will print a string of the following form its
|
||||||
|
standard output.
|
||||||
|
|
||||||
|
> NSM_URL=osc.udp://foo.bar.net:17551/
|
||||||
|
|
||||||
|
This is the OSC URL for the daemon process. If this URL is included
|
||||||
|
in the environment (by either using a fixed port number or starting
|
||||||
|
nsmd early in the initialization process [like in your .xinitrc]
|
||||||
|
extracting the URL from its output.) then any NSM capable client
|
||||||
|
will join the current session when started, even if started from
|
||||||
|
outside the Non Session Manager interface (e.g. by your desktop
|
||||||
|
environment's program launch menu).
|
||||||
|
|
||||||
|
|
||||||
|
::: Multiple NSMD Instance
|
||||||
|
|
||||||
|
When dealing with multiple instances of nsmd, whether they be on the
|
||||||
|
same machine or different machines, it is most convenient to use
|
||||||
|
fixed port numbers.
|
||||||
|
|
||||||
|
:::: Distributed Session Management
|
||||||
|
|
||||||
|
In some situations it is necessary to have different audio programs
|
||||||
|
running on different machines connected by S\/PDIF\/or analog wiring
|
||||||
|
or over TCP\/IP as achieved by `netjack`. Usually the reason for
|
||||||
|
doing this is that neither machine is powerful enough to do all the
|
||||||
|
DSP or synthesis by itself.
|
||||||
|
|
||||||
|
Needless to say, these configurations have historically been
|
||||||
|
extremely difficult to manage--requiring heavy scripting or lots of
|
||||||
|
manual setup.
|
||||||
|
|
||||||
|
NSM is the first and currently only system capable of managing these
|
||||||
|
sessions.
|
||||||
|
|
||||||
|
Let us assume the following conditions for our example:
|
||||||
|
|
||||||
|
+ We want to distribute a session across two hosts, Host-A and Host-B, on the local area network
|
||||||
|
+ Each host has a completely independent file system (i.e. not NFS)
|
||||||
|
+ We have appropriate access to both hosts.
|
||||||
|
|
||||||
|
The first step is to decide what port numbers to use. Let's choose
|
||||||
|
`6661` for Host-A and `6662` for Host-B.
|
||||||
|
|
||||||
|
If either host is running a firewall, then these ports must be opened explicitly!
|
||||||
|
|
||||||
|
To start the daemon on host A:
|
||||||
|
|
||||||
|
> user@host-a:~$ nsmd --detach --session-root "$HOME/distributed-nsm-sessions" --osc-port 6661
|
||||||
|
|
||||||
|
To start the daemon on host B (conveniently from host A, via rsh)
|
||||||
|
|
||||||
|
> user@host-a:~$ rsh host-b nsmd --detach --session-root "\$HOME/distributed-nsm-sessions" --osc-port 6662
|
||||||
|
|
||||||
|
Note that in the above example, there is a backslash in "$HOME",
|
||||||
|
this is because otherwise the variable would be expanded on the
|
||||||
|
local machine, giving the local value rather than what we intended.
|
||||||
|
|
||||||
|
Now that both daemons are running, we can start the Non Session
|
||||||
|
Manager interface with the following command:
|
||||||
|
|
||||||
|
> user@host-a:~$ non-session-manager --nsm-url osc.udp://host-a:6661 --nsm-url osc.udp://host-b:6662
|
||||||
|
|
||||||
|
The Non Session Manager interface will then connect to the daemons
|
||||||
|
on both hosts. Creating a new session will create separate session
|
||||||
|
files on each host. When adding a client, the interface will present
|
||||||
|
the user with a choice of which host to invoke the client on. Aside
|
||||||
|
from that it is just like managing any other session. Sessions can
|
||||||
|
be opened, saved, switched between, etc. and the desired effect will
|
||||||
|
be seen on each host.
|
||||||
|
|
||||||
|
:::: Multiple Sessions On One Host
|
||||||
|
|
||||||
|
Simply starting two (or more) instances of the Non Session Manager
|
||||||
|
interface on the same machine (when the NSM\_URL environment
|
||||||
|
variable is unset) will result in the ability to have two different
|
||||||
|
sessions open at the same time on the same host. The instances are
|
||||||
|
prohibited from opening two instances of the same session.
|
||||||
|
|
||||||
|
Imagining a useful application of this feature is left as an
|
||||||
|
exercise for the user.
