About Swift Package Manager and LLDB

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.

I would just enable all of the logging and post it here or if the log is very big put the log into a pastebin.

OK You want it locally
It is just the PerfectTemplate without ANY CHANGE (Perfect framework by PerfectlySoft)
(Also Kitura makes the same problem, but I didn't try to get a full log to see whether the same problem or not)

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)

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

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.

WEIRD WEIRD WEIRDIt seems it is threading issueBecause when I tried to breakpoint on line 71 file main.swift (like you did)It worked perfectlyI even could "frame variable" fully
It seems that perfect framework when handle an HTTP request, it makes something in threads, I don't know how to debug it
Try to debug on line 31 then invoke an HTTP request on localhost:8181, you will reproduce the error

But it works when I use xcode (Again this is irreleveant, this is not the solution)

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 ??

Sorry for misleading informationIt is NOT only threading issue
If you try on Kitura, then try debug Application.swift on line 21 for exampleIt gives the same problem while it is still on Thread #1
Also when tried to debug main.swiftWhile there is no closures, GCD here

I think the problem is something in the SPM because all works fine on Xcode

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.

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.

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.

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.

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

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.

Swift doesn’t seem to be reporting whatever the error is, I just see:

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.

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.

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.

Hey Fadi, do you think you can thread this email thread a little better? Right now (for whatever reason) a bunch of your emails are getting new threads in mail. It would be a lot easier to track/respond to the email if you always responded in the same mail thread.

Notice the difference between the results of the two compilations (Xcode and SPM):

It seems the modules are compiled and linked SEPARATELY in Xcode, and this succeed in debugging
But 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.
