exchange: support sorting URLs by client-side preferences Not all bundles are appropriate for all clients. For example, someone with a slow Internet connection may want to prefer bz2 bundles over gzip bundles because they are smaller and don't take as long to transfer. This is information that a server cannot know on its own. So, we invent a mechanism for "preferring" server-advertised URLs based on their attributes. We could invent a negotiation between client and server where the client sends its preferences and the sorting/filtering is done server-side. However, this feels complex. We can avoid complicating the wire protocol and exposing ourselves to backwards compatible concerns by performing the sorting locally. This patch defines a new config option for expressing preferred attributes in server-advertised bundles. At Mozilla, we leverage this feature so clients in fast data centers prefer uncompressed bundles. (We advertise gzip bundles first because that is a reasonable default.) I consider this an advanced feature. I'm on the fence as to whether it should be documented in `hg help config`.
