Mac - app does not connect to the debug server

[jcward]

Hi @mpoint4u -- I think the issue you're experiencing is different than #19, so I've moved it here to its own thread.

@mpoint4u said on Dec 16:

same happens to me, when I try to start the actual executable on 64bit Mac (in '/Export/mac64/cpp/bin/DisplayingABitmap.app/Contents/MacOS/DisplayingABitmap') from the command line (because it does not launch from VS Code directly ... )

and if I try to debug the compiled program from VS Code debug perspective (via launch.json) I get a few error messages for missing property 'program' or wrong type value ....
....

PS: I am using Haxe Compiler 3.2.1 / hxcpp: [3.2.193] / lime: [2.7.0] with MacBook 64 bit on OSX El Capitan 10.11.1

all in all ... VS Code seems to be a quite nice editor / debugging enviroment ... (have to try it on Linux soon ... )

[jcward]

@jcward said:

@mpoint4u thanks for the note. You can safely ignore those errors in launch.json. The latter are a bug in vscode ("node" isn't the only debug type that's accepted.) My debug adapter doesn't use "program" -- I suppose you could add "program":"" to make validation happy, but it hasn't caused problems for me without it.

I think the app seems like it isn't launching because it's actually crashing near time 0. Check out /tmp/adapter.log and see what's at the end. You might see something like this:

1450216349.08474: Starting VSCHaxeServer port 6972...
1450216349.08487: Launching application...

So in the above, the client starts (pid=13210) and connects, but after I send a couple commands (Files, FilesFullPath, SetCurrentThread, etc) the client disconnects (and I think crashes with the stack trace I put in the bug report above.)

The /tmp/adapter.log file is available on linux and mac, and if you create a C:\tmp folder on windows, also there.

Later in the evening I will try to debug the DisplayingABitmap - test project in VS Code on 64bit Linux ... and see what I will get ... and report then ...

[jcward]

Hi @mpoint4u - in your log, you can see that the client never connected -- in the below "disconnect" means you hit the stop button in the GUI:

1450452095.19971: VSCHS: Listening for client connection on localhost:6972 ...
1450452107.12429: Reading 101 bytes...

1450452107.12439: Got command: disconnect

What're you're missing is:

1450216366.30884: VSCHS: Received connection from 127.0.0.1.

Did you put the new HaxeRemote(true, "127.0.0.1"); in your code, as well as the steps in "your app needs to" in the readme? Those things cause it to launch a debug client. I've also seen weird problems on mac where server/client uses 127.0.0.1 / localhost and they don't connect.

Thanks for your feedback!

[mpoint4u]

Hi Jeff,

now I switched in the
new HaxeRemote(true, "127.0.0.1");
statement in the constructor of the Main.hx class ...

recompiled ... and ...

... it's still not connecting ... !!

I will check all the other stuff, which could disrupt a socket connection on '127.0.0.1'
(firewall is turned off in my case, a bunch of other connections on '127.0.0.1' exists - as you can see in the screenshot ... ).

How could I get a proof that the 'server part' of the hxcpp-debug-adapter effectively works on Mac OSX ... ?!?

Cheers,
Marcus

[mpoint4u]

could it be that, for whatever reason, the current MacOSX operating system allows only port connections higher than 10000 on the local network interface ('127.0.0.1' or 'localhost') ... ?!? It just hits the eye that all client connections on '127.0.0.1' in my above screenshot are higher than that ... I had a quick Google research on that, but that did not reveal very much either ...

[jcward]

While your vscode is sitting waiting for the connection, try:

telnet localhost 6972

or

telnet 127.0.0.1 6972

From a terminal window. This will attempt to connect to the server. If you get "connection refused", then something with the network or server isn't working. If you get "Connected to localhost, Escape character is ^]" then it did connect, and the problem is on the client app side.

Also, do i pull and rebuild (haxe build-mac.hxml) -- I put in some more error/warning messages that could help in pointing out issues.

[mpoint4u]

Did you pull and rebuild? There should be a warning that the client didn't reconnect.

So then, make sure the app has all 3:

1. Compiled in -debug mode
2. new HaxeRemote(...)
3. -D HXCPP_DEBUGGER

[mpoint4u]

just tried another few things, but it looks like that the compiles client NOT EVEN tries to connect ...

my Main.hx looks like this:

---

package;

import openfl.display.Bitmap;
import openfl.display.BitmapData;
import openfl.display.Sprite;
import openfl.Assets;

#if debug
import debugger.HaxeRemote;
#end

class Main extends Sprite {

public function new () {

#if debug
new debugger.HaxeRemote(true, "127.0.0.1");
//new debugger.Local(true);
#end

    super ();

    var bitmap = new Bitmap (Assets.getBitmapData ("assets/openfl.png"));
    addChild (bitmap);

    bitmap.x = (stage.stageWidth - bitmap.width) / 2;
    bitmap.y = (stage.stageHeight - bitmap.height) / 2;

}   

}

---

and compiles without a halt ....

[mpoint4u]

but when I try to build it from the command line, I get ....

[jcward]

Hmm, it seems like you have all the elements. I'll do some more Mac testing this evening and get back to you. It could also be interesting, while your code server is waiting for a connection, to try launching it from the commandline to see what your app says in the terminal.

(I don't see the null references in the output above -- did you paste the whole output?)

[mpoint4u]

OK, I will check that later ... have to leave for meeting family at dinner ... ;-)

[mpoint4u]

Hi Jeff ... seems like I got the "Mac version" of the "Blue Screen of Death" on my MacBook now ...

after some recherche I assume it will be something like
https://discussions.apple.com/message/29125114#29125114

so it looks like I am not able to investigate for some time on our issue...
anyway, I am on Linux Mint 17 "Qiana" now on my second Notebook now,
and as this distro is based on Ubuntu 14.04 ...
https://www.google.com.ua/?gfe_rd=cr&ei=Yzp7Vre6PIyu8wftkL2IBA&gws_rd=ssl#q=linux+mint+17+is+based+on+ubuntu+LTS
... I can at least continue to use vscode-hxcpp-debug on Linux (as long as it takes to restore the MacBook to MacOSX Yosemite ... no El Capitan anymore ...))

not particularely GOOD news, but ... anyway ... cheers & a happy holiday season !!

[jcward]

@mpoint4u - sorry about your crash. If you're up and running again, FYI, a large fix was checked in #19 / #31. I'm not sure it's the same as the issue you're experiencing, but it may be worth trying again.

[arthurferrai]

Hi, I tried right now on osx and got the very same result. Any suggestions?
Edit: It turns out you need to pass complete osx executable on runCommand (like "MyApp.app/Contents/MacOS/MyApp"). Then it executes and attaches debugger correctly.

[jcward]

@arthurferrai ah, ok, I'm not entirely familiar the conventions of OSX apps directory structure. So the test openfl app's launch.json run path may need to be modified?

[arthurferrai]

@jcward the run path is ok, the problem is with run command. My entry is as follows:

{
    "name": "OSX: Debug",
    "runtimeExecutable": "${execPath}",
    "args": [
        "runPath=${workspaceRoot}/export/mac64/cpp/bin/",
        "runCommand=adventure-card-game.app/Contents/MacOS/adventure-card-game",
        "runInTerminal=false"
    ],
