From 195caf3ae4b2150a7234de64d0907d74f9a4c0be Mon Sep 17 00:00:00 2001 From: Anthony Towns Date: Fri, 11 Apr 2008 11:07:57 +0000 Subject: [PATCH] * dak/utils.py: build_file_list() extra parameters so it can build a file list for checksums-foo fields. Don't use float() to compare formats, because Format: 1.10 should compare greater than Format: 1.9 (use "1.9".split(".",1) and tuple comparison instead) * dak/process_unchecked.py: check_md5sum becomes check_hashes and check_hash. If changes format is 1.8 or later, also check checksums-sha1 and checksums-sha256 for both .changes and .dsc. --- ChangeLog | 11 +++++++ dak/process_unchecked.py | 67 ++++++++++++++++++++++++++-------------- daklib/utils.py | 38 +++++++++++++++-------- 3 files changed, 79 insertions(+), 37 deletions(-) diff --git a/ChangeLog b/ChangeLog index 65b0c7c5..90475c4f 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,14 @@ +2008-04-11 Anthony Towns + + * dak/utils.py: build_file_list() extra parameters so it can + build a file list for checksums-foo fields.
