Strange Checksum errors

Postby joergvf » Mon Apr 03, 2006 2:15 pm

Hi,

using Subversive 1.0.0M9 I'm seeing more and more errors like this:

Code: Select all

Error
2006-04-03 16:11:35.40
Some resources were not updated.

Other developers in our team who use Subversion don't get these errors.

Is there anything I could do about this?

Actually other people here get the same problem, some remedies can be found at http://jroller.com/page/dunpanic?entry=subversion_base_checksum_mismatch.

Sorry for bothering.

On the Link you provided are several Solutions, but i can't figure out what to do. Can you post the "Best Practice" Solution, with a very easy Description how to do this in Eclipse?

F.e. i tried to delete the Folder and replace it with latest from Repository. -> Didn't work for me. Got the Checksum Error again.

Why does this Problem occour?
Will you fix this error?

Is any Developer reading this Forum???

Hello all,

We forwarded these errors to JavaSVN authors, but unfortunately they are not able to reproduce this problem. Sorry for complications.

Checksum mismatch for... error

Postby vlp » Thu Nov 09, 2006 1:12 pm

The "Checksum mismatch for..." error appears after I try to commit file that is being locked by another program. I think it's easy to reproduce this behavior.

When commiting locked file, the error message appears: "The process cannot access the file because another process has locked a portion of the file".

After this moment, all successive attempts to commit that file fail with "Checksum mismatch" error. Cleanup, Update operations do not help.

I am using Subversive plugin 1.1.0.M8a. Previous versions show the same errors.

Dear vlp,

Thank you for tips to reproduce the problem. I tried described approach and found that committing of locked file finishes successfully. Probably there are other locking conditions? How your files were locked? What tool did locking?

We will make another try to reproduce it.

The error appears when committing file exclusively locked by some other app. I mean Windows shared access file lock, not SVN lock. For example when I try to copy this locked file by any file manager, I get "File sharing violation", obviously SVN plugin gets the same and probably it's reason of following checksum errors and corrupted working copy.
