Windows client appears mute

[jmkgreen]

We built clients for both Linux and Windows. The Linux one behaves as expected, the Windows one does not print the results of commands at all.

The Windows client happily prints the help content and that of version, but does not print things like classpath contents.

Stepping through the server we can see both clients executing code as expected and both clients receive network traffic so we're a little puzzled why one prints the returned value but the other does not. Continuing to investigate this...

[jmkgreen]

Incidentally we also tried the Windows binary as shipped by JRuby - again mute.

Thanks for looking into it! Please let me know what else you find.

[jmkgreen]

I doubt you meant to close an issue that is current? Could you reopen please (I have no such button)?

[martylamb]

Oops, your right. I did not mean to close it. Thanks.

Guys, any update on this issue?
I faced with this problem on Windows 7 x64 (I also tried it on Ubuntu 13.04 x64 and it works fine!). HelloWorld example doesn't print anything. It seems that client returns immediately and doesn't output stdout and stderr.
By the way I'm using 32-bit ng.exe (which was built by myself). Also tried to build x64 version but compiled executable doesn't work (particulary it just does nothing).

I tried to debug C-source a little bit and it seems that inside processnailgunstream() socket returns only 1 byte instead of 5 (CHUNK_HEADER_LEN). And this byte is zero. To be continued...

I am also having this issue (win7 64bits). Please help.... (thanks!)

[jimpurbrick]

I've recently checked in a number of win32 fixes, do you have these problems with the current tip of master?

[jimpurbrick]

Also, do the examples work for you? I tested the Heartbeat, Echo and HelloWorld examples on a 64 bit windows 7 box.

[bouteill]

When I launch the examples, nothing happens. Here is how I do this (to make sure I am doing this right):
In CMD line: I type:
java -jar nailgun-server-0.9.2-SNAPSHOT.jar
It then says: NGServer 0.9.2-SNAPSHOT started on all interfaces, port 2113.
So the server seems to start properly.
To launch the examples, I type (in a directory where the compiled examples JAR file is located):
ng nailgun-examples-0.9.2-SNAPSHOT.jar
And nothing happens.....
I also tried:
ng com.martiansoftware.nailgun.examples.HelloWorld.class
And nothing happens either. (I get a command prompt back, as if nothing had happened)

[azhuchkov]

It appears to work with latest changes from @jimpurbrick. Great job!!! Thanks!!! Tested on Echo and HelloWorld.
@bouteill Don't you forget to recompile ng.exe? AFAIK it was changed since then. I'm using GCC bundled with MsysGit - just add Msys's bin folder into your PATH and fire gcc -o ng.exe ng.c -lwsock32 -O3 -Wall -pedantic -s -O3.

By the way, the correct way to test is:
ng com.martiansoftware.nailgun.examples.HelloWorld (without .class)

[bouteill]

I downloaded the latest sources from github, recompiled using "mvn clean install" as stated in the startup manual.
I launched the server (new jar)
java -jar nailgun-server-0.9.2-SNAPSHOT.jar
It then says: NGServer 0.9.2-SNAPSHOT started on all interfaces, port 2113.
So the server seems to start properly.

I recompiled the ng.exe using the command above ( gcc -o ng.exe ng.c -lwsock32 -O3 -Wall -pedantic -s -O3 )
I used the recompiled examples as well and tried to launch the example HelloWorld
ng com.martiansoftware.nailgun.examples.HelloWorld (in the directory where nailgun-examples-0.9.2-SNAPSHOT.jar is located) and now get the following error message on the client side when attempting to launch the example:

java.lang.ClassNotFoundException: com.martiansoftware.nailgun.examples.HelloWorld

at com.martiansoftware.nailgun.NGSession.run(NGSession.java:254)

And the server side says:
NGSession 1: (idle) disconnected

I am getting closer, I guess... Would anyone know what I am missing here?
Thank you for your help!!!

PS: I also tried to run the client using the command:
ng ng-cp nailgun-examples-0.9.2-SNAPSHOT.jar com.martiansoftware.nailgun.examples.HelloWorld , but this time, I get no output...

[bouteill]

PS2: Nevermind, I think I got my solution. The proper way to launch the client on the examples is using the following command:
ng com.martiansoftware.nailgun.examples.HelloWorld -ng-cp nailgun-examples-0.9.2-SNAPSHOT.jar
Using this command, I get my "Hello, World" back ;)
(I am a novice, but I think this should be specified a little more clearly in the startup guide). Nevertheless, great job, and thank you for your help!)

[azhuchkov]

@bouteill you could avoid all that stuff with -ng-cp by running mvn exec:java -Dexec.mainClass=com.martiansoftware.nailgun.NGServer from nailgun-examples directory. It described at quickstart guide. Probably you missed it.
Anyway glad to hear that you found a proper solution.

[bouteill]

Well, I kind of like the idea to be able to separate:
(1) the initialization of the server, and
(2) running the examples on the client.
It is helpful in my opinion to give you an idea of how to run your own programs later on (which is not the case when one runs the mvn command)...

Everyone happy with me closing this now?

[jmkgreen]

Has there been a release? Or are you asking if you can mark this as fixed
rather than closed?

I've not had time to download and test yet.
