| # Since we try to pass substitutions as-is to some tests, we must "escape" |
| # them in case they contain other substitutions. Otherwise, the substitutions |
| # will be fully expanded when passed to the tests. For example, we want an |
| # %{exec} substitution that contains `--execdir %T` to be passed as-is, without |
| # substituting the directory. This way, the test itself can populate %T as it |
| # sees fit, and %{exec} will respect it. |
| # |
| # To solve this problem, we pickle the substitutions and base64 encode that |
| # to pass it to the test, and we decode and unpickle the substitutions from |
| # within the test. |
