Improve workspace lock error dialog. #2347

raghucssit · 2024-10-01T11:24:33Z

Write workspace lock info like user, host, java process id, display properties onto .lock file if the lock was successful. Read the current lock data in case of lock was unsuccessful and shown it in error dialog.
If the .lock file has no info then nothing is shown. For older eclipse versions.

see #2343

raghucssit · 2024-10-01T11:24:51Z

@iloveeclipse FYI

BeckerWdf · 2024-10-01T11:39:12Z

Can you pls. provide a screenshot showing the new dialog?

laeubi · 2024-10-01T12:01:02Z

By the way if on the lock dialog is worked, it would be great to have a cancel button!

Currently one can only Retry or Choose where on the second one can then finally cancel the startup of Eclipse. Instead I have most of the time not the case that another user locked the workspace but I have just an instance already running. In that case a early Cancel would be great.

Dialog looks like this with this fix.

Maybe User, Host, etc. should be written in with an uppercase first letter (because they are some kind of label)

tomaswolf · 2024-10-01T14:32:07Z

And these display strings must be localizeable.

Unfortunately it looks like writing to the locked file unlocks it again!

I'm able to start multiple Eclipse instances on same workspace now :-(

Fixed all the review comments. Committed as separate commit to help the review.
Later I will squash them as single commit.

I have changed the approach now.
First we will check if the workspace is locked, If not then write the data who is going to lock it.(Also backup .lock file data)
Now initiate actual lock, If we are successful all good Otherwise write back what was there before onto .lock file.

Also please rebase on latest master before next push

I went through comments. I will refactor the code with .loc_info file approach. which will not have any risks. If file exists we show owner info otherwise old error dialog.

I will do this change as separate PR. As we are only improving error message here. Other suggestions are fixed.

All the review suggestions are fixed.

BeckerWdf · 2024-10-10T08:50:53Z

How does the UI look now?

Now it looks like this.

laeubi · 2024-10-10T09:59:31Z

Now it looks like this.

The labels are still not aligned, it should be something like

User:    abcd
Host:    234.567.7
Display: :1

BeckerWdf · 2024-10-10T10:06:08Z

Display: :1

Especially this looks strange because of the two ":". I knot that's they displays are called. Maybe we should put all the values into single or double quotes. So that is would look like

User:    "abcd"
Host:    "234.567.7"
Display: ":1"

laeubi · 2024-10-10T10:15:14Z

Display has format <hostname>:<sequence number>.<screen number> so the format can potentially be longer.

Sure. But this does not contradict my proposal...

I am using System.getenv("DISPLAY"); to read display number. I use 2 monitors it always returns value as shown above. like :1 for vnc display 1.

I have introduced tab spacing and single quotes for the lock owner details. Now the dialog looks like this.

That looks nice now. Thanks

laeubi · 2024-10-14T06:56:09Z

@BeckerWdf do you think the quotes are required with the new layout? They look a bit misplaced from my point of view.

merks · 2024-10-14T07:40:48Z

@BeckerWdf do you think the quotes are required with the new layout? They look a bit misplaced from my point of view.

Yes, unless one expects there might be trailing or leading whitespace that needs to be called out because that relevant, then the quotes seem like merely noise. And I believe in this case there is no interesting whitespace.

BeckerWdf · 2024-10-14T08:49:46Z

Yes. In the new layout we can get rid of them from my point of view.

...g.eclipse.ui.ide.application/src/org/eclipse/ui/internal/ide/application/IDEApplication.java

Write workspace lock info like user, host, java process id, display properties onto a new file .lock_info if the lock was successful. Read the current lock data in case of lock was unsuccessful and show it in error dialog. If the .lock_info does not exist or the file has no info then nothing is shown. For older eclipse versions. see eclipse-platform#2343

raghucssit · 2024-10-14T21:15:47Z

Fixed review comments. Now dialog looks like this.

iloveeclipse

Thanks Raghu! Looks good now.

iloveeclipse · 2024-10-15T05:56:28Z

...g.eclipse.ui.ide.application/src/org/eclipse/ui/internal/ide/application/IDEApplication.java

+	private File createLockInfoFile(URL workspaceUrl) throws Exception {
+		File lockInfoFile = getLockInfoFile(workspaceUrl);
+
+		if (lockInfoFile.exists())


Next time please don't forget to put "if" in a block.
