action-107 pending

action-107 due in 2 weeks

<trackbot> Set action-107 Organise cfc on breaking change for the main thread scriptprocessornode due date to 2014-08-21.

ScriptProcessorNode in Workers - continued

cwilso: at last call we discussed options
... rough consensus was that we should examine possibility of removing main thread spn
... seemed to be general agreement to consider it as synchronous callback
... discussed with TAG friends Domenic and Alex
... at this point just needs to be written up into the spec

olivier: best to have a draft to build a CfC on

cwilso: can use an editor's (sub)draft
... we need to discuss pulling the old spn
... we have gotten some flak for other removals, we should expect some for SPN though if we remove it at this point

joe: has the alternative - introducing a new node with a new name been considered?
... code that assumes old behaviour will be problematic

cwilso: could also change how the node is created
... question is how long do we want developers to continue using the old node/behaviour

joe: current design unworkable by developers
... trying to cut up the problem
... agree to retiring the old behaviour asap
... for a while we had warning in console
... would like a solution that doesn't block introduction of new behaviour

olivier: how many (high profile) of it? should be different to noteon/noteoff

padenot: seen it quite a lot

olivier: seems like new name/constructor and deprecation warning better?

joe: note that this is different from previous name changes - this is semantic/behaviour change

cwilso: excellent point. closest comparison is createaudiobuffer

olivier: if we create a new node, and organise a slow deprecation of the old one
... should help?

cwilso: am concerned about how deliberately and forcefully we organise that deprecation
... don't want to ship a v1 spec that has it
... deprecation is a dangerous thing
... as is creates a precedent of "supporting it"
... we need to organise it well, decide on shutting it off at same time in implementations
... the longer we let it sit, the more likely we will have to leave it forever

olivier: suggest draft removes old way entirely and we can have CFC about that + commitment to remove from implementations ASAP

<cwilso> ACTION: cwilso to remove old scriptprocessornode and implement new one, issue draft. [recorded in http://www.w3.org/2014/08/07-audio-minutes.html#action01]

<trackbot> Created ACTION-108 - Remove old scriptprocessornode and implement new one, issue draft. [on Chris Wilson - due 2014-08-14].
