From dff3fa13579fad491095124de59045f6f13f7769 Mon Sep 17 00:00:00 2001 From: Daira Hopwood <daira@jacaranda.org> Date: Thu, 5 Sep 2013 19:04:38 +0100 Subject: [PATCH] Mon Dec 5 04:40:01 GMT 2011 Brian Warner <warner@lothar.com> * setup.py: get version from git or darcs This replaces the setup.cfg aliases that run "darcsver" before each major command with the new "update_version". update_version is defined in setup.py, and tries to get a version string from either darcs or git (or leaves the existing _version.py alone if neither VC metadata is available). Also clean up a tiny typo in verlib.py that messed up syntax hilighting. --- setup.cfg | 14 ++-- setup.py | 128 +++++++++++++++++++++++++++++++++++ src/allmydata/util/verlib.py | 2 +- 3 files changed, 136 insertions(+), 8 deletions(-) diff --git a/setup.cfg b/setup.cfg index 5be32286..0d682035 100644 --- a/setup.cfg +++ b/setup.cfg @@ -32,10 +32,10 @@ find_links=misc/dependencies tahoe-deps ../tahoe-deps # (See ticket #142.)
