Reviewers

In ClearCase it is only possible to commit changes to the LATEST version. The new code checks for cases where the CHECKEDOUT version is not LATEST and notifies the user that a merge is needed.

The new code also makes LATEST the base version for the changeset instead of the original, hiding the changes that are already under version control (and hopefully already reviewed).

Tested rbt post manually.

Using it in production for the last month.

This should probably call re.escape on branch, in case the branch name has regex special characters in it.

  1. Most of these comments are style-related. I don't understand clearcase well enough to really know how correct this is (or whether it will regress other usage). Can you comment the Vtree methods more to explain what's going on?

    Can we do one string and one format operation? Adjacent string literals will get concatenated without using + operators (like in C). Please also change "try" to "tried".

    die("Error: you tried to post changes that you cannot check-in.\n"
        "Merge from the LATEST version to clear this error.\n"
        "Offending version: %s@@%s\n"

    This should call re.escape on the path before formatting it into the regex.

    This should also prefix the string with r (`r"{0}...").

    This should prefix the string with r (r"\s...").

    I also don't see any format characters in the string, so the .format() call is useless.
