By configuration it is possible to specify which download schemes and commands are enabled.
The configuration must be done in the
gerrit.config of the Gerrit server.
[download] command = checkout command = cherry_pick command = pull command = format_patch scheme = ssh scheme = http scheme = anon_http scheme = anon_git scheme = repo_download
The download section configures the allowed download methods.
download.command : Commands that should be offered to download changes.
Multiple commands are supported: * `checkout`: Command to fetch and checkout the patch set. * `cherry_pick`: Command to fetch the patch set and cherry-pick it onto the current commit. * `pull`: Command to pull the patch set. * `format_patch`: Command to fetch the patch set and feed it into the `format-patch` command. If `download.command` is not specified, all download commands are offered.
download.scheme : Schemes that should be used to download changes.
Multiple schemes are supported: * `http`: Authenticated HTTP download is allowed. * `ssh`: Authenticated SSH download is allowed. * `anon_http`: Anonymous HTTP download is allowed. * `anon_git`: Anonymous Git download is allowed. This is not default, it is also necessary to set [gerrit.canonicalGitUrl] (../../../Documentation/config-gerrit.html#gerrit.canonicalGitUrl) variable. * `repo_download`: Gerrit advertises patch set downloads with the `repo download` command, assuming that all projects managed by this instance are generally worked on with the repo multi-repository tool. This is not default, as not all instances will deploy repo. If `download.scheme` is not specified, SSH, HTTP and Anonymous HTTP downloads are allowed.
download.checkForHiddenChangeRefs : Whether the download commands should be adapted when the change refs are hidden.
Git has a configuration option to hide refs from the initial advertisement (`uploadpack.hideRefs`). This option can be used to hide the change refs from the client. As consequence fetching changes by change ref does not work anymore. However by setting `uploadpack.allowTipSha1InWant` to `true` fetching changes by commit ID is possible. If `download.checkForHiddenChangeRefs` is set to `true` the git download commands use the commit ID instead of the change ref when a project is configured like this. Example git configuration on a project: [uploadpack] hideRefs = refs/changes/ hideRefs = refs/cache-automerge/ allowTipSha1InWant = true By default `false`.
