SSH keys, ``~/.netrc`` and ``~/.ssh/config`` files can be used as alternatives. +Using tags with the git fetcher may cause surprising behaviour. Bitbake needs to +resolve the tag to a specific revision and to do that, it has to connect to and use +the upstream repository. This is because the revision the tags point at can change and +we've seen cases of this happening in well known public repositories. This can mean +many more network connections than expected and recipes may be reparsed at every build. +Source mirrors will also be bypassed as the upstream repository is the only source +of truth to resolve the revision accurately. For these reasons, whilst the fetcher +can support tags, we recommend being specific about revisions in recipes. .. _gitsm-fetcher: |
