SI-7629 Remove view bounds from spec #118
Conversation
|
These are still in the language, seems to soon to unspec them. |
|
The compiler is a superset of the things specified in the spec, I think it is perfectly fine if the compiler keeps supporting things which are deprecated, but I don't think we should burden the actual spec with deprecations. |
|
@retronym Anyway, given the usual speed at which spec PRs are handled, this commit will probably merged right in time with Scala 2.13. |
|
@odersky doesn't read github pings; you should mail him directly if you want review. |
|
I concur with Jason. There's no point to change the spec if the compiler still supports it. They will be removed, but the right way to do it is to change everything in sync. |
|
Once the spec is in the main repo and follows the branching structure, we can update it there. |

I've reopened and assigned to milestone 2.12 |
Reduce the memory footprint of BlockInfo objects This pull request reduces the memory footprint of all BlockInfo objects and makes additional optimizations for shuffle blocks. For all BlockInfo objects, these changes remove two boolean fields and one Object field. For shuffle blocks, we additionally remove an Object field and a boolean field. When storing tens of thousands of these objects, this may add up to significant memory savings. A ShuffleBlockInfo now only needs to wrap a single long. This was motivated by a [report of high blockInfo memory usage during shuffles](https://mail-archives.apache.org/mod_mbox/incubator-spark-user/201310.mbox/%3C20131026134353.202b2b9b%40sh9%3E). I haven't run benchmarks to measure the exact memory savings. /cc @aarondav
