batch checking for modifications?

[Niemann, Hartmut]

Hello *!

 

I would like to check in a batch file, whether my working copy is still identical to HEAD.

 

Reason: an automatic build creates a tag (after the build) and I want to make sure that the input files are unchanged.

 

Steps:

1. Create a fresh working copy
2. Build
3. Commit build results (I know that this is not the recommended way, but the project members want/need it that way)
4. Tag

 

The problem:

If a commit in one of the input files happens between (1) and (3), the build results don’t match the input after (3).

I could tag the source with revision of (1) and the output with the revision of (3), but that is ugly and normally unnecessary (nobody is supposed to do a check in while a to-be-tagged (testing or) release candidate is built).

But if my input files change while building and tagging, results will be inconsistent.

So I would like to tag with the revision of the commit (3) and either

(a) check before tagging, that the input has not been changed in between and abort or

(b) check after tagging and remove the inconsistent tag.

 

Svn diff does not seem to have a suitable return code. It returns 0 whether it has found a difference or not.

Does anyone have an idea how I could accomplish my goal?

 

Regards

Hartmut

Does TortoiseSVN's Check for modifications, Check repository work for you?

I think the following would be a command line equivalent:

svn diff -r BASE:HEAD

That will show any changes from the BASE revision (ie, what you checked out in step 1) and the HEAD revision (current repository revision). It seems to work also with mixed-revision-wcs.

Kind regards,

Daniel

How about locking the repository during the bild process?

why not tag first, then build from the tag and add the build results
to the tag?
