# Create some references, perhaps run pack-refs --all, then try to |
|
# create some more references. Ensure that the second creation fails |
|
# with the correct error message. |
|
# Usage: test_update_rejected <before> <pack> <create> <error> |
|
# <before> is a ws-separated list of refs to create before the test |
|
# <pack> (true or false) tells whether to pack the refs before the test |
|
# <create> is a list of variables to attempt creating |
|
# <error> is a string to look for in the stderr of update-ref. |
|
# All references are created in the namespace specified by the current |
|
# value of $prefix. |
