Undoing changelist in P4Python

Question

I have an issue with undoing changes in Perforce using p4python given that I have sumitted the changelist that I now want to undo. My idea is first to create a changelist and then run the undo. However, Iam doing something wrong and the file doesnt get undone.

# new_cl is the created changelist
# cl_to_undo is the changelist to undo.
# description is string
P4.run("undo", '-c'+new_cl, filePath+"@" + cl_to_undo, description)

# Submit
P4.submit(new_cl)

Would appriciate any help. Thanks.

Answer 1

The undo command doesn't take a description argument.

C:\Perforce\test>p4 help undo

    undo -- Undo a range of revisions

    p4 undo [-n] [-c changelist#] file[revRange]

You should set the Description field of new_cl at the time you create it (presumably you have some code earlier in your script that creates a pending changelist with p4.get_change and p4.save_change, and it sets a description -- put your description text in there).
