Oh, Migration tool - I hate ye! (Just for the moment ...)

[Brian Schau]

Build #3780 on all systems ...

Migrating attachments on my development PC from the database to a filesstore - works.  Yay!
Migrating attachments on our test rig from the database to a filesstore - works.  Double yay!
Migration attachments on our production system from the database to a filesstore ... kaboom:

C:\RavenDB\Migration>Raven.Migration.exe http://localhost:8080/ --database=MyDatabase --filesystem=MyFS --delete-copied-attachments
System.NullReferenceException: Object reference not set to an instance of an object.
   at Raven.Migration.MigrationTasks.CopyAttachmentsToFileSystem.Execute() in c:\Builds\RavenDB-3.0-Unstable\Raven.Migration\MigrationTasks\CopyAttachmentsToFileSystem.cs:line 52
   at Raven.Migration.Program.Parse(String[] args) in c:\Builds\RavenDB-3.0-Unstable\Raven.Migration\Program.cs:line 94

... apparently the attachmentInfo.Key is null ...

It's 11 o'clock in the evening - this is a bad time for this kind of problem to happen ...   :-)

Are you sure that you are using Raven.Migration 3780? The NRE there is because the attachmentInfo is null, and that was fixed three weeks ago

Yes.  I am aware of that - I raised the issue :-)

But - apparently our database contains "broken" attachments - this is what seems to save the day for me:

		var attachment = commands.GetAttachment(attachmentInfo.Key);
		if (attachment == null)
			continue;

... the last two lines makes the process go on ...    At least from getting absolutely no percentage output to (currently) 3%:

C:\Users\Administrator\Desktop\Debug>Raven.Migration.exe http://localhost:8080/ --database=MyDB --filesystem=MyFS --delete-copied-attachments

(I hope the patient will pull through :-)
