From 2e85a0c8abe29f9adad2ec0a977629ba90723973 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Martin=20=C3=85gren?= Date: Sun, 22 Apr 2018 20:12:49 +0200 Subject: http-fetch: make `-a` standard behaviour MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This is a follow-up to a6c786fce8 (Mark http-fetch without -a as deprecated, 2011-08-23). For more than six years, we have been warning when `-a` is not provided, and the documentation has been saying that `-a` will become the default. It is a bit unclear what "default" means here. There is no such thing as `http-fetch --no-a`. But according to my searches, no-one has been asking on the mailing list how they should silence the warning and prepare for overriding the flipped default. So let's assume that everybody is happy with `-a`. They should be, since not using it may break the repo in such a way that Git itself is unable to fix it. Always behave as if `-a` was given. Since `-a` implies `-c` (get commit objects) and `-t` (get trees), all three options are now unnecessary. Document all of these as historical artefacts that have no effect. Leave no-op code for handling these options in http-fetch.c. The options-handling is currently rather loose. If someone tightens it, we will not want these ignored options to accidentally turn into hard errors. Since `-a` was the only safe and sane usage and we have been pushing people towards it for a long time, refrain from warning when it is used "unnecessarily" now. Similarly, do not add anything scary-looking to the man-page about how it will be removed in the future. We can always do so later. (It is not like we are in desperate need of freeing up one-letter arguments.)
