-1 This series revolves around adding support for series parsing: this patch (and subsequent, related patches) focuses on adding a different, large and currently unrequired feature. This secondary feature should be done in a different series, as suggested previously:


Addressing your points from that previous mail:

AJAX is great, but it's not necessary for series support. I'm all for responsive applications (in all senses), but I have yet to see a complaint about patchwork's resource demands nor a user requesting the functionality that AJAX would provide. If you personally think patchwork then by all means, make it happen but do so in another series.

What does this give us, besides slightly nicer "architecture"? The end user won't see this, but they will see the bugs and design oversights that will inevitably be present. APIs are hard work and once they're out there there's no going back: we want to make sure the one we implement is "right". This is something that needs to be discussed in its own thread.

Now this is a real issue. However, why not fix this in another series rather than trying to replace something that is well working but perhaps not as clean as it could be? The XML-RPC API may need some work but there's nothing fundamentally wrong with it (RPC is not dead: it's just out of fashion).

In summary, while I understand what you're trying I think you're going about it the wrong way. There may be some valid reasons for using REST, but we are currently able to do patch support with XML-RPC and we can sure do series support the same way :)
