Re: [swift-users] Swift 4.0 bug in concurrent array access

2018-01-08 Thread ‫Fadi Botros‬ ‫ via swift-users

What about double checking?


Something like that
if counter != 0 { throw exc }
counter += 1if counter != 1 { throw exc }counter += 1

I think the performance penalty is just a check and an increment
It could be disabled after optimization or in release version to increase 
performance

1st: How to invoke the thread sanitizer?

Check out this article on developer.apple.com: 
https://developer.apple.com/documentation/code_diagnostics/thread_sanitizer/enabling_the_thread_sanitizer

2nd: I think making something like ConcurrentModificationException of Java 
should be a little better experience (if it will not make, or make a small 
performance penalty, also if it makes performance penalty, it would be 
activated only when you make a debug version or non-optimized version)


I don't exactly disagree, but my understanding is that the work to do such a 
thing is nearly equivalent to having thread sanitizer on all the time. But 
maybe there's a simpler model that we could still turn on in debug builds. Can 
you file a bug report requesting this now that bugs.swift.org is back up?

Something like ConcurrentModificationException ought to be cheaper than the 
thread sanitizer. The thread sanitizer works hard to detect every concurrency 
error. ConcurrentModificationException typically does something simple and 
cheap that catches errors sometimes but makes no attempt to be exhaustive.
Objective-C's fast enumeration protocol includes a mechanism like this. The 
collection can have a simple mutation counter, and the enumerator captures the 
counter's value at the start and checks that the value is unchanged as the 
enumeration proceeds.

Does ObjC synchronize the mutation counter?  My understanding is that that 
counter was used to detect mutation while iteration on a single thread, not 
across threads.

The mutation counter is not synchronized; this is safe for correct code. An 
un-synchronized counter can still sometimes catch mutations from other threads.

[swift-users] Swift 4.0 bug in concurrent array access

2018-01-08 Thread ‫Fadi Botros‬ ‫ via swift-users

I'm on macOS Sierra 10.12.6, and using Swift 4.0Tried to access the array

It seems the modules are compiled and linked SEPARATELY in Xcode, and this 
succeed in debuggingBut in SPM, all are compiled as one module (it may have 
submodules)
I think if you provide something compiles to dynamic link libraries on Linux 
(and SPM in general) like frameworks on macOS, it will solve the problem

It does look like this is a known bug (not yet fixed) in SPM:
https://bugs.swift.org/browse/SR-3280
The bug isn’t fixed yet (apparently it’s blocked on a swift compiler issue.)  
There’s a workaround in that report, though I don’t know how viable it is.  
Anyway, you can track that bug to see when this gets fixed.

It isn’t quite as mysterious as that.  lldb emulates the context of the frame 
you are stopped in when you run “frame variable” or “expression”.  It looks 
like PerfectTemplate doesn’t have a problem, and doesn’t rely on modules that 
we can’t reconstruct.  But some of the other modules do have problems.  For 
instance, if I let the program come up, interrupt it and switch to a frame in 
the PerfectHTTPServer, then I see:
(lldb) expr let $mystr = "Some string"error: in auto-import:failed to get 
module 'PerfectHTTPServer' from AST context:error: missing required modules: 
'PerfectCHTTPParser', 'PerfectCZlib'

But that’s not the only one with problems, and I’m still not getting any useful 
error messages back from swift.  I’ll have to dig into this more.

I think really like I said in the last message, it is a threading issueBecause 
debugging on Line 71 (which you debugged): It gives that you are on the main 
thread Thread #1When on line 31 (which I debugged): It gives that you are on 
Thread #2 (then you can't import any modules, nor print any variables, etc... 
The error you have its details on the previous messages)

Does GCD work perfectly with SPM ??? Do I have to do something special to 
enable GCD debugging without Xcode ??

The log for “print self” was unfortunately captured too late.  Reading in the 
PerfectTemplate module had already failed, and so any subsequent attempt will 
just report it as failed.  To get the complete error log for this, you need to 
put:
log enable -f /tmp/lldb-type-log.txt lldb types
in your ~/.lldbinit file and then start a fresh debugging session and capture 
the whole session.
The failure from the REPL  is because you have to tell the REPL where to look 
for other frameworks from which it might load modules.  You can pass 
appropriate -I, -L and -F flags to the “swift” invocation too tell the compiler 
lldb’s using to implement the REPL where to look for this module.
The example you gave seems to be a MacOS X example.  The binary type was MachO 
etc.  If this is just a small example that you are using to demonstrate the

[swift-users] بخصوص: About Swift Package Manager and LLDB

2017-11-06 Thread ‫Fadi Botros‬ ‫ via swift-users

Also please notedI think it is a SPM issue not an LLDB oneBecause when compiled 
on the same mac with Xcode (Swift package manager generate Xcode project), then 
use xcode-buildLLDB works perfectly in this circumstances
I think you should refine the compilation script generated by SPM to generate 
something like Xcode results (I think Xcode itself uses normal Swift toolchain, 
I think it does nothing here more than generating a better compilation/linking 
script)

Swift doesn’t seem to be reporting whatever the error is, I just see:
((SwiftASTContext*)0x7f8c555c84a0)->GetModule('PerfectTemplate') -- failed with 
no error

That’s not very helpful.  Again, I’ll probably need to make this happen locally 
to see what went wrong.  If you have a project that shows the issue which you 
can make available, please file a bug with a description of how you build and 
debug this app, I’ll take a look.

 الموضوع: Re: [swift-users] About Swift Package Manager and LLDB
  
The log for “print self” was unfortunately captured too late.  Reading in the 
PerfectTemplate module had already failed, and so any subsequent attempt will 
just report it as failed.  To get the complete error log for this, you need to 
put:
log enable -f /tmp/lldb-type-log.txt lldb types
in your ~/.lldbinit file and then start a fresh debugging session and capture 
the whole session.
The failure from the REPL  is because you have to tell the REPL where to look 
for other frameworks from which it might load modules.  You can pass 
appropriate -I, -L and -F flags to the “swift” invocation too tell the compiler 
lldb’s using to implement the REPL where to look for this module.
The example you gave seems to be a MacOS X example.  The binary type was MachO 
etc.  If this is just a small example that you are using to demonstrate the 
problem, can you file a PR with the swift bug reporter with this example and 
how you built/ran it and we can take a look here.  That’s probably easier than 
trying to pass logs back and forth.

whether the same problem or not)

Also there is some very weird thing happens
When I use ^C to stop debuggingthen REPLimport PerfectTemplate
There is no error
But when use breakpointThe error happens
Is there something weird about breakpoints ?
Also please note that on macOS when I use SPM to convert project to Xcode 
project and compile using xcode-build all work perfectly(This is inconvienient 
since servers are Linux, web debugging must be on Linux)
