2023-03-22	SSHMaster: pause logger to show password prompt	Alexander Bantyev
	Pause logger before starting SSH connections, and resume it after the connection is established, so that SSH password prompts are not erased by the logger's updates.
2022-10-22	Defer to SSH config files for ForwardAgent option	Austin Kiekintveld
	Currently, Nix passes `-a` when it runs commands on a remote machine via SSH, which disables agent forwarding. This causes issues when the `ForwardAgent` option is set in SSH config files, as the command line operation always overrides those. In particular, this causes issues if the command being run is `sudo` and the remote machine is configured with the equivalent of NixOS's `security.pam.enableSSHAgentAuth` option. Not allowing SSH agent forwarding can cause authentication to fail unexpectedly. This can currently be worked around by setting `NIX_SSHOPTS="-A"`, but we should defer to the options in the SSH config files to be least surprising for users.
2022-02-25	Remove std::string alias (for real this time)	Eelco Dolstra
	Also use std::string_view in a few more places.
2021-04-07	restoreSignals() + restoreAffinity() -> restoreProcessContext()	Eelco Dolstra

2021-02-25	distributed builds: load remote builder host key from the machines file	Graham Christensen
	This is already used by Hydra, and is very useful when materializing a remote builder list from service discovery. This allows the service discovery tool to only sync one file instead of two.
2020-02-14	Fix PR_SET_PDEATHSIG results in Broken pipe (#2395)	Tobias Möst
	The ssh client is lazily started by the first worker thread, that requires a ssh connection. To avoid the ssh client to be killed, when the worker process is stopped, do not set PR_SET_PDEATHSIG.
2019-12-13	Simplify	Eelco Dolstra

2019-12-12	libstore/ssh: Improve error message on failing `execvp`	Profpatsch
	If the `throw` is reached, this means that execvp into `ssh` wasn’t successful. We can hint at a usual problem, which is a missing `ssh` executable. Test with: ``` env PATH= ./result/bin/nix-copy-closure --builders '' unusedhost ``` and the bash version with ``` env PATH= ./result/bin/nix-copy-closure --builders '' localhost ```
2019-11-22	getEnv(): Return std::optional	Eelco Dolstra
	This allows distinguishing between an empty value and no value.
2019-02-05	Revert "Restore parent mount namespace before executing a child process"	Eelco Dolstra
	This reverts commit a0ef21262f4d5652bfb65cfacaec01d89c475a93. This doesn't work in 'nix run' and nix-shell because setns() fails in multithreaded programs, and Boehm GC mark threads are uncancellable. Fixes #2646.
2018-11-13	Restore parent mount namespace before executing a child process	Eelco Dolstra
	This ensures that they can't write to /nix/store. Fixes #2535.
2018-08-03	SSHMaster: Bypass SSH when connecting to localhost	Eelco Dolstra
	This is primarily useful for testing since it removes the need to have SSH working.
2018-03-20	SSHMaster: Optionally pass -v to ssh	Eelco Dolstra

2017-08-16	Disallow SSH host names starting with a dash	Eelco Dolstra

2017-07-30	Replace Unicode quotes in user-facing strings by ASCII	Jörg Thalheim
	Relevant RFC: NixOS/rfcs#4 $ ag -l \| xargs sed -i -e "/\"/s/’/'/g;/\"/s/‘/'/g"
2017-05-02	build-remote: Ugly hackery to get build logs to work	Eelco Dolstra
	The build hook mechanism expects build log output to go to file descriptor 4, so do that.
2017-03-21	Honor $NIX_SSHOPTS again	Eelco Dolstra
	NixOps needs this.
2017-03-03	SSHMaster: Make thread-safe	Eelco Dolstra

2017-03-03	Improve SSH handling	Eelco Dolstra
	* Unify SSH code in SSHStore and LegacySSHStore. * Fix a race starting the SSH master. We now wait synchronously for the SSH master to finish starting. This prevents the SSH clients from starting their own connections. * Don't use a master if max-connections == 1. * Add a "max-connections" store parameter. * Add a "compress" store parameter.
