Re: [swift-dev] Swift Syntax Structured Editing Library

[David Farler via swift-dev]

Hi all,

I've now merged this to master. Just want to say I appreciate the enthusiasm - 
I'm really excited about all of the things this work will enable.

You can track progress in the following places:

https://github.com/apple/swift/tree/master/lib/Syntax/README.md
For an overview of the APIs, implementation, and testing information.

https://github.com/apple/swift/tree/master/lib/Syntax/Status.md
For implementation status and referenced SRs.

https://bugs.swift.org/browse/SR-3968?filter=10739
I'll be using the 'Syntax', 'Format', and 'Migrator' labels to track tasks and 
bugs. I'll be working quickly but I'll try to peel off some starter bugs and 
give a shout out when I can.

Stay Swifty-
DF

Re: [swift-dev] Profiling ARC

[David P Grove via swift-dev]

Sorry, I shouldn't have assumed that everyone know what the Computer
Language Benchmark Game was.

There's a set of 10 toy benchmarks written in 30 different languages that
are available here: http://benchmarksgame.alioth.debian.org/   The webpage
also lets you see the results of regular performance runs and see how the
various programs stack up against each other.

As usual with small benchmarks, there are lots of ways in which the
programs aren't realistic.

After dispatch became available on Linux with Swift 3, I had a side project
of going through the Swift implementations and adding concurrency to a few
Swift programs that didn't have it already.

regex-dna is the main outlier for Swift (which is why I had profiled it).
There's enough ARC overhead that using dispatch actually made it slower...
The sequential version for of regex-dna for Swift is:
http://benchmarksgame.alioth.debian.org/u64q/program.php?test=regexdna&lang=swift&id=2
My slower concurrent version is:
http://benchmarksgame.alioth.debian.org/u64q/program.php?test=regexdna&lang=swift&id=3

I suspect that the main fix for improving the performance of this program
is actually doing something in CoreFoundation, but I got sidetracked and
didn't finish looking into it.

  hmm,  I wonder if your method of profiling is really finding all the
  ARC operations.  The Swift version of regex-dna is about 25x slower
  than the Java version (on Linux).  I looked at some prof profiles
  about a month ago and at the time roughly 80% of all execution
  samples were attributed to swift_retain/swift_release operations
  coming from CoreFoundation's regex implementation.


Question. Where is this regex-dna benchmark, is it in the swift benchmark
suite?

Here is a Swift version:
http://benchmarksgame.alioth.debian.org/u64q/program.php?test=regexdna&lang=swift&id=2
 



And here is a Java version:
http://benchmarksgame.alioth.debian.org/u64q/program.php?test=regexdna&lang=java&id=7
 


And, BTW, Swift version is not multi-threaded, but Java version is.

Question. Where is this regex-dna benchmark, is it in the swift benchmark suite?

[swift-dev] Reduce app startup time by combining swift-libs

[Michel Loenngren via swift-dev]

All,

When starting an app that includes swift these libs are being loaded:

*libswiftCoreGraphics.dylib *
*libswiftDispatch.dylib  *
*libswiftObjectiveC.dylib*
*libswiftCore.dylib*
*libswiftDarwin.dylib*
*libswiftFoundation.dylib*

which adds considerable delay to our app startup time (compared to running
a pure objective-c codebase). Is anybody aware of a way to reduce startup
by combining these libs into a single lib for faster load time?

Kind regards

Michel

hmm,  I wonder if your method of profiling is really finding all the ARC
operations.  The Swift version of regex-dna is about 25x slower than the
Java version (on Linux).  I looked at some prof profiles about a month ago
and at the time roughly 80% of all execution samples were attributed to
swift_retain/swift_release operations coming from CoreFoundation's regex
implementation.

[Alex L via swift-dev]

Should be fixed now by cherry-pick db7d8d26a585aacc0a77b230d7f3887dbe873dbf!

[Ankit Aggarwal via swift-dev]

Hmm, I have not seen this assertion before. My commits did not change anything 
in 'Basic' module.
