Re: [subversive-dev] How to invoke Lock operation before Commit operatio

[Alexander Gurov <alexander.gurov@xxxxxxxxxxxx>]

Hello,

That won't work because lock action performs real operation asynchronously. In order to avoid LockDialog and to check operation execution status you'll need to do something like this:

                                int result = Window.CANCEL;

filesToCommit = allFilesToCommit;

CustomCommitDialog dialog = new CustomCommitDialog(shell,

commentPanel);

dialog.setAllFilesToCommit(allFilesToCommit);

result = dialog.open();

if (result == Window.OK) {

LockOperation op = new LockOperation(resources, "lock message text", false /*true in order to force locks*/);

UIMonitorUtility.doTaskBusyDefault(op);

result = op.getSeverity() == IStatus.OK ? Window.OK : Window.CANCEL;

}

return result;

Also please note that there is no need of try/catch blocks because all the errors are handled by LockOperation and UIMonitorUtility classes themselves. You'll only need to check operation execution status afterwards.

Best regards,
Alexander.

Hello Alexander,

What I need is invoke Lock operation immediatly before Commit operation and if the Lock fail, to cancel Commit operation. I used this way:

                                int result = Window.CANCEL;

filesToCommit = allFilesToCommit;

CustomCommitDialog dialog = new CustomCommitDialog(shell,

commentPanel);

dialog.setAllFilesToCommit(allFilesToCommit);

try {

result = dialog.open();

if (result == Window.OK) {

LockAction lock = new LockAction();

IAction action = "">

lock.runImpl(acao);

}

} catch (Exception e) {

result = Window.CANCEL;

}

return result;

I used the pre-lock subversion's hook to simulate the Lock fail, but the Commit operation is not cancelled. Is it possible do this? How can I do invoke Lock operation in background without the Lock Dialog?

Best regards, 

Rodrigo

Hello Rodrigo,

The API related to the commit dialog were initially created for the specific project, so it may be not the best to work with.
Regarding how to do it now - it is relatively easy. Anyway now you're implementing ICommitDialog interface. Right? In the method open() of this interface you're doing something like this:
            public int open() {
                DefaultDialog dialog = new DefaultDialog(shell, commentPanel);
                return dialog.open();
            }
So, you may as well change the code:
            public int open() {
                DefaultDialog dialog = new DefaultDialog(shell, commentPanel);
                int retVal = dialog.open();
                if (retVal == Window.OK) {
                    // invoke Lock here
                }
                return retVal;
            }
The flaw of this solution is that you will run your code in the UI thread. That is not a very nice thing, but... oh well, that is why I said that API created for a single project is not the best thing to use, it misses many important points. So, if you have any ideas regarding future improvements you're welcome to share your opinion here: https://bugs.eclipse.org/bugs/show_bug.cgi?id=327399
