2014-07-10 nix-copy-closure -s: Do substitutions via ‘nix-store --serve’Eelco Dolstra1-0/+1
This means we no longer need an SSH master connection, since we only execute a single command on the remote host.

C++11 lambdas ftw.
2014-07-10 nix-copy-closure: Fix race conditionEelco Dolstra1-4/+4
There is a long-standing race condition when copying a closure to a remote machine, particularly affecting build-remote.pl: the client first asks the remote machine which paths it already has, then copies over the missing paths. If the garbage collector kicks in on the remote machine between the first and second step, the already-present paths may be deleted. The missing paths may then refer to deleted paths, causing nix-copy-closure to fail. The client now performs both steps using a single remote Nix call (using ‘nix-store --serve’), locking all paths in the closure while querying. I changed the --serve protocol a bit (getting rid of QueryCommand), so this breaks the SSH substituter from older versions. But it was marked experimental anyway. Fixes #141.

2014-02-26 Add use-ssh-substituter setting.Shea Levy1-0/+12
It defaults to false and can be overridden by RemoteStore. Untested currently, just quickly put this together

2014-02-08 Add download-via-ssh substituterShea Levy2-0/+138
This substituter connects to a remote host, runs nix-store --serve there, and then forwards substituter commands on to the remote host and sends their results to the calling program. The ssh-substituter-hosts option can be specified as a list of hosts to try. This is an initial implementation and, while it works, it has some limitations: * Only the first host is used * There is no caching of query results (all queries are sent to the remote machine) * There is no informative output (such as progress bars) * Some failure modes may cause unhelpful error messages * There is no concept of trusted-ssh-substituter-hosts Signed-off-by: Shea Levy <shea@shealevy.com>
