From mboxrd@z Thu Jan 1 00:00:00 1970 From: Thomas De Schampheleire Date: Thu, 3 Jan 2019 21:40:19 +0100 Subject: [Buildroot] [PATCH 04/11] support/download: implement source-check in hg backend In-Reply-To: <20190103204026.23512-1-patrickdepinguin@gmail.com> References: <20190103204026.23512-1-patrickdepinguin@gmail.com> Message-ID: <20190103204026.23512-5-patrickdepinguin@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net From: Thomas De Schampheleire Note: the implementation is different (better) than what used to be in Buildroot before source-check was removed. The original implementation: hg incoming --force -l1 would only verify that the repository exists, not that the requested revision is present. An already better implementation is: hg incoming --force -l1 -r but compared to the next solution it has a large resource consumption on the local machine. In the background, the full repository is first downloaded. The implemented solution is: hg identify -r which operates directly on the remote repository.
