New submission from Trent Buck <[EMAIL PROTECTED]>:
[Apologies if this arrives twice; I'm having MUA problems.]
Darcs does not warn users when they attempt to remove a checkpoint
patch, and gives confusing/obtuse errors afterwards.
Below is a minimal transcript demonstrating the problem. First, the
setup:
$ mkdir x
$ darcs init --repodir x
$ touch x/x
$ darcs rec -lam x --repodir x
Finished recording patch 'x'
$ darcs tag -m y --repodir x
Finished tagging patch 'TAG y'
$ touch x/z
$ darcs rec -lam z --repodir x
Finished recording patch 'z'
$ darcs optimize --checkpoint --repodir x
Checkpointing tag:
Sat Aug 11 23:52:15 EST 2007 Trent W. Buck <[EMAIL PROTECTED]>
tagged y
Done optimizing!
$ darcs get --partial x p
Copying patch 2 of 2... done!
Applying patch 1 of 1... done.
Finished getting.
Now, note that no warning is given that the patch to be unrecorded is
a checkpoint:
$ darcs unrec -p TAG --repodir p
Sat Aug 11 23:52:15 EST 2007 Trent W. Buck <[EMAIL PROTECTED]>
tagged y
Shall I unrecord this patch? (1/?) [ynWvpxqadjkc], or ? for help: y
Finished unrecording.
Note that having removed the checkpoint patch, darcs gives extremely
unintuitive error messages:
$ darcs get --partial p
Directory '/tmp/tmp.MjkngQ6090/p' already exists, creating repository as
'/tmp/tmp.MjkngQ6090/p_0'
Copying patch 2 of 2...darcs:

openBinaryFile: does not exist (No such file or directory)
$ darcs unrec --repodir p
