From af6d7ef7ff0f09ae0abcce9e42335d123e9ceb12 Mon Sep 17 00:00:00 2001 From: Petr Stodulka Date: Wed, 23 Aug 2023 12:04:05 +0200 Subject: [PATCH] load data files: update hints in error messages and prepare for the download drop MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit As the leapp upgrade data files are nowadays part of the install rpm, there is no need to download them anymore. Also, we plan to drop the service providing the data files online in future. For that reason, update all texts and related error messages so people are not instructed to visit obsoleted article and do not try to apply invalid (obsoleted) data files anymore. Right now, we are keeping the functionality for the data files download, but the fetch functino is already updated and prepared to stop trying to download the files if not present. As we have the functionality already present, I think we should keep a possibility of the download for additional custom data files (not provided by us) in custom actors, but for the official data files we will require them in future to be present locally only. NOTE: regarding another planned changes soon, skipping update of unit-tests Co-authored-by: Michal Hečko --- .../deviceanddriverdeprecationdataload.py | 5 ++- .../libraries/pes_event_parsing.py | 17 +++++++--- .../libraries/repositoriesmapping.py | 20 +++++++----- .../system_upgrade/common/libraries/fetch.py | 31 ++++++++++++++----- 4 files changed, 49 insertions(+), 24 deletions(-) diff --git a/repos/system_upgrade/common/actors/loaddevicedriverdeprecationdata/libraries/deviceanddriverdeprecationdataload.py b/repos/system_upgrade/common/actors/loaddevicedriverdeprecationdata/libraries/deviceanddriverdeprecationdataload.py index 7d41aa0842..3caa4e0ac0 100644 --- a/repos/system_upgrade/common/actors/loaddevicedriverdeprecationdata/libraries/deviceanddriverdeprecationdataload.py +++ b/repos/system_upgrade/common/actors/loaddevicedriverdeprecationdata/libraries/deviceanddriverdeprecationdataload.py @@ -16,9 +16,8 @@ def process(): deprecation_data = fetch.load_data_asset(api.current_actor(), data_file_name, asset_fulltext_name='Device driver deprecation data', -
