Re: [swift-corelibs-dev] Query on bridgeable classes

2017-02-21 Thread Philippe Hausler via swift-corelibs-dev 
The reasoning why is that some classes are designed as a has-a relationship 
instead of an is-a relationship. For example a NSRunLoop has a CFRunLoopRef but 
a NSString is a CFStringRef. This means that you cannot pass a NSRunLoop to a 
function that takes a CFRunLoopRef by design. Where-as any method that takes a 
CFStringRef can take a NSString.

The reasoning for this behavior is to match the behavior of the objective-c 
version of Foundation.

For example  NSURLComponents is not CFBridgeable.

[swift-corelibs-dev] Memory growth regression in NSMutableData

2017-02-21 Thread Sai Kanduri via swift-corelibs-dev 
Hi All,
 
I could see a memory leak when running a simple loop that creates NSMutableData objects and appends to them with swift-3.1-DEVELOPMENT-SNAPSHOT-2017-02-14-a-ubuntu16.10>I have not seen this leak with swift-3.0.2.
 
Following is the Leak Summary from Valgrind :
 
With Swift-3.0.2==18606== LEAK SUMMARY:==18606== definitely lost: 16 bytes in 1 blocks==18606== indirectly lost: 20 bytes in 1 blocks==18606== possibly lost: 0 bytes in 0 blocks==18606== still reachable: 74,893 bytes in 10 blocks==18606== suppressed: 0 bytes in 0 blocks==18606== Rerun with --leak-check=full to see details of leaked memory
Swift 3.1
18411== LEAK SUMMARY:==18411== definitely lost: 247,463,936 bytes in 59 blocks==18411== indirectly lost: 0 bytes in 0 blocks==18411== possibly lost: 171,966,640 bytes in 42 blocks==18411== still reachable: 74,885 bytes in 10 blocks==18411== suppressed: 0 bytes in 0 blocks
https://bugs.swift.org/browse/SR-3966 is the corresponding bug report.
 
Have anyone observed the same ?

Do you have a couple of examples that you're referring to?

Hi everyone,

To be more precise, I would like to know why few classes are not
CFBridgeable.

Thank you.

[swift-corelibs-dev] Query on bridgeable classes

2017-02-21 Thread Nethra Ravindran via swift-corelibs-dev 
Hi,

I see that some classes are bridgeable and some are not. It would be great
if someone can explain why few classes are not bridgeable.

Thank you!
