Eclipse Plugin for the Debug Perspective

[Former Member]

Hello,

I try to write an Debugger Plugin for AiE. My Target is, to read some Informations of different Variables (Internal Tables, References etc), match this Infos, and show its in a tree.

But i'm not really successfull.
I read the "Getting started..." Document from: http://scn.sap.com/docs/DOC-59944

and the linked Blogs from Martin Steinberg and Christian Drumm.

But my Problem is a little bit specially, because i want to use my Plug-In in the Debug Perspective...
For Example: When i try the "Hello World" Plugin from Martin Steinberg: http://scn.sap.com/docs/DOC-54728

it works.
I have the "Hello World" Plug-In Project in Eclipse, when i start it, an second Eclipse Instance is starts.

In the Second Eclipse instance i have the new Menu-Button for the Plugin, and can start the plugin. => Everything is okay.

But: When i connect to a Abap Project (in the second eclipse), and start the debugger, the second Eclipse freeze

and hangs up.... Have someone an Idea to solve this Problem?

I think its a Problem of the second Eclipse Instance and ADT.

What i already tried:

When i use not an ABAP Project (in the second eclipse), and use a Java Project, and start the Debugger for Java,
the second Eclipse hangs up too.   => i thought its a generally Eclipse Problem.

BUT: I tried a complete new Eclipse Installation (Without installed ADT), and with this eclipse, i can start my Plug-In Project =>

Second Eclipse Instance starts, and doesn't hang up when i start the Debugger there.

I installed the Eclipse some times again (with and without ADT) and i only have the Problem when ADT is installed.

P.S. I use Luna and the newest ADT-Version.

Have someone an Idea?

Regards

Stefan

Hi Stefan,

I didn't face such issue so far. But maybe ABAP debugger in both Eclipse sessions is blocking somehow. Could you try to disable ABAP debugger (in your first Eclipse)?

To disable the ABAP debugger for your project process the following steps:

- Select your project in Project Explorer

- Select "Properties" in the context menu

- Open page "ABAP Development > Debug"

- Disable the checkbox "Enable debugger"

Hello Michael,

Thank you for the Tip. But in my first Eclipse i doesn't have any ABAP Projects. I only have one "Plug-In Project" for Eclipse.
When i go to Properties in the Project Explorer i doesn't have the option "Abap Development".
This Option is only there, if its an Abap Project.

In the Morning i tried following:
1. New Eclipse Installation (only with Plug-In Environment, WITHOUT ADT).
2. New Eclipse Installation (with ADT) => Debugger Worked.

In my first Eclipse, i can define a "TARGET Eclipse for Plug-Ins". Normaly there is an Reference to the own Eclipse Folder...

I changed the Target to my Second Eclipse Installation (With ADT).

Result: When i start my Plug-In Project a second Eclipse starts.

In the first Eclipse i haven't ADT. In the Second Eclipse i have ADT.

But i have the Problem again. => Debugger in the second Eclipse freeze and hangs up.

Very strange...

Regards

Hi Stefan,

the blocking Eclipse instance can either be caused by a breakpoint (on Java or ABAP side), or a deadlock during startup.  For both cases taking a look at the thread's states is useful:

1. Start the second instance in debug mode (use the bug symbol in the toolbar, not the run button).
2. Open "Debug" view in the first instance.  In its tree select the second node form the top (the so called debug target) and hit the Pause button in the toolbar to stop all threads.
3. Expand all thread nodes below the debug target, then select "Copy Stack" form the context menu on the target.
4. Paste the text in here.

Hello Christian,

Thank you for your Help.

Here are the Infors from the Threads.

I Make two Szenarios.

The First Szenario (which you described), the second Eclipse doesn't freeze, because i didn't start

the Debugger in the second Eclipse instance

- Start the second instance in debug mode

- Open "Debug" view in the first instance.

- stop all threads

Here is the Text. (after this Text, have an other scenario with frozen Eclipse..)

    Daemon Thread [[ThreadPool Manager] - Idle Thread] (Suspended)   

In the next Scnario, the Eclipse is frozen.

- Start the second Eclipse Instance in debug mode

- Connect to a Abap Project in the second Eclipse

- Set an Breakpoint in Abap Source Code  (Second Eclipse)

- Start the Abap Transaction in the Second Eclipse, and the Breakpoint is reached

    => Second Eclipse Instance freeze.

Hi Stefan,

thanks for the data.  However, this doesn't help too much since you dumped the list of threads instead of the stack frames within the threads.  So, as a second try, please expand all nodes one level deeper.  Also, you don't need to send the data for the unproblematic scenario.

Regards,

Christian

[Former Member]

Hey Christian,

Sorry. My mistake...

Here are the stack frames within the threads.

Szenario

- Start Second Eclipse in Debug-Mode

- Connect to a Abap Project in Second Eclipse

- Set Breakpoint in Abap Source-Code (Second Eclipse)
- Start Abap Transaction to reach the Breakpoint => Second Eclipse freeze

- Start Debug Perspective in Frist Eclipse

- Expand All Nodes of the Threads

- Copy Stack:

Hello,

I found the solution.

My Eclipse (First Eclipse Instance) use the JRE and not the JDK.
In Eclipse you can find the Setting in => Window | Preferences | Java | Installed JREs.

I installed the newest JDK. And switched in Eclipse from JRE to the JDK folder.
Now the second Eclipse can debug on SAP Systems . (without freeze)

Regards

Stefan
