Better Progress Monitoring

[eblen]

The progress monitor for sync'ing is never updated. Also, progress monitoring for other operations, such as git operations or build operations, may also need to be improved.

[rolandschulz]

Partly done. Committed even though it is only partly done to reduce the number of possible merge conflicts. Status:
Done:
- Monitor is passed everywhere it is needed
- Converted to jgit monitor for jgit transport
- Should allow cancel in most places (see Missing)

Missing:
 - Monitor needs to be used correctly in CommandRunner (depends on Issue #13)
 - Tasks have to be created and updated to have moving progress bar

I just uploaded my latest changes. There were several merge conflicts, so I had to revert a few things. (I had already done translatable strings, and I had refactored synchronization.) I kept all of your new progress monitoring code except for a few places inside the sync call. I copied it, though, for later reference.

[rolandschulz]

you copied it where? And why did you not keep all in the sync call?

[eblen]

I simply copied it to a text file so I can have it if I need it later while working on the monitor.

It looks like the only monitor code I didn't include is:

    while (!syncLock.tryLock(50, TimeUnit.MILLISECONDS)) {
                                    if (progress.isCanceled()) {
                                            throw new CoreException(new Status(IStatus.CANCEL,Activator.PLUGIN_ID,Messages.GitServiceProvider_1));
                                    }
                            }

I wasn't sure where to place this code (our implementations were quite different), and I didn't know what its purpose was.

[rolandschulz]

you made another mistake. You removed the finally blocked.
I committed a fix.

The tryLock loop replaces lock(). It aquires the lock but allows the
progress-monitor to cancel the operation.

Please don't just leave things out in a merge. If you are not sure than ask
before you commit a merge. Finding mistakes in a merge takes a long time (if
I woudn't have reviewed everything I wouldn't have caught the missing
finally block). Thus making sure merges are correct is really important.

Which finally block? The finally block in sync that unlocks the lock was still there.

The best solution is to avoid complex merges altogether, which means we should commit and upload frequently. I wasn't able to upload until this morning (more network problems - I can explain later.) So I had two days of work in one commit. Had I committed earlier, it would have all been much simpler. Oh well, live and learn...

the finally block with the monitor.done()

f197af9 fixes it mostly. Remaining depends on issue #13
