Subject: [RFC PATCH 07/13] bundle-uri client: add boolean transfer.bundleURI setting
Date: Thu,  5 Aug 2021 17:07:23 +0200	[thread overview]
Message-ID: <RFC-patch-07.13-f0e4052de4-20210805T150534Z-avarab@gmail.com> (raw)
In-Reply-To: <RFC-cover-00.13-0000000000-20210805T150534Z-avarab@gmail.com>

The yet-to-be introduced client support for bundle-uri will always
fall back on a full clone, but we'd still like to be able to ignore a
server's bundle-uri advertisement entirely.

This is useful for testing, and if a server is pointing to bad
bundles, they take a while to time out etc.

Since we might see the config in any order we need to clear out any
accumulated bundle_uri list when we see transfer.bundleURI=false
setting, and not add any more things to the list.
