Hi,

I think the the sort should be in the client as I think it's a display tweak
and should be an option, like -t in ls.

I agree that this could be an option, but I don't see why it should be in the client. Moving the logic there forces everybody that writes a library to implement their own sorting.

For the same reason we move all -q parameters from server to client, display shouldn't be handled by the server. It should provide raw output via the api.
Imagine a web client, it might want to sort with every column, we can't implement this in the server.

At least it's my opinion, @creack @crosbymichael

My vote would be to keep display logic on the client.

+1 on @vieux regarding -q parameters, but I think it would be nice if the server could sort the list prior to send it.
Like this, the server still send raw data, but in a consitent way. If a client need to sort it in a different way, then it would be up to him.
At the moment, when you do 2 docker images, you will have 2 different output which is not ideal.

Yeah, that's the point of this change. I'd like to have the server to send the list of images in a consistent way. Right now you get a list according to how docker reads the graph, either it takes the heads or the map. The result is not always in the same order, which is kind of a pain to use. I think returning always a list of images sorted by creation is consistent and it makes sense in a lot of cases. It's also easy to scan and understand by the human brain.

I don't mind to move the sorting to the client, I only need to change a couple of lines, but I'd really like to get a consistent list of ordered images from the server.

Ok, that sounds totally reasonable to me, sry.

When an image is tagged 2 times, the 2 tags will have the same creation date, therefor, the sort will still be random on these. If the point if to be consistent, maybe we should add a name sort for images with the same creation data ?

ubuntu is a great exemple.

Indeed, we also need to order alphabetically

Sorry for the delay in my replays, it was a crazy couple of weeks. I agree that it should sort by creation date and name.

LGTM
@calavera thanks
