From: Tim Johnson Date: Wed, 30 Oct 2019 21:29:52 +0000 (-0700) Subject: Update Bash library X-Git-Tag: v0.48.0^0 X-Git-Url: https://gerrit.linuxfoundation.org/infra/gitweb?a=commitdiff_plain;h=4ac79cd48227bbbfadbab995dc4535a61a7ee26f;p=releng%2Fglobal-jjb.git Update Bash library The lf-venv-activate() function has been deleted. The lf-venv-create() function has been renamed lf-activate-venv(). The lf-activate-venv() function now creates temporary venvs and updates the PATH. Remove required 'python' argument and '--python' flag. Add two new functions: lf-git-validate-jira-urls() and lf-jjb-check-ascii().
