BUG: "cvs diff -r HEAD" gets current branch based on revision...

[R Bresner]

Howdy,

 

We've recently upgraded to 1.11( NT/Solaris clients, Solaris server)

and have noticed a new behavior when using the the HEAD tag alias,

which we believe is a bug.

 

To reproduce the problem:

 

1. Add a new file to mainline, new revision 1.1

2. Tag -b the file to a branch.

3. modify and checkin the file in mainline, creating 1.2.

4. update the file to the created branch, retrieving sticky-tagged 1.1

5. cvs diff -r HEAD file

 

The HEAD is determining the current branch based from the

1.1 revision number, instead of the sticky-tag name, and so

the diff -rHEAD is diffing to the mainline 1.2, instead of the

1.1 head of the branch. When a change is checked into the

branch (creating 1.1.2.1), cvs diff -rHEAD correctly determines

the current branch. It is only when the branched file hasn't yet

been changed in the branch that the -rHEAD is coming out wrong.

 

In CVS-1.9, which we've just upgraded from, the -rHEAD would

correctly identify the current branch the file is sticky-tagged to,

and diff to that branch.

 

I don't know what else to put in a reporting a bug email, so I'll

just be on my way...

 

Cheers,
