2013-09-18	build-remote.pl: Don't use substituters on the remote	Eelco Dolstra
	It's kinda pointless to check substituters on the remote side, since we just checked them locally.
2013-07-18	Revert "build-remote.pl: Enforce timeouts locally"	Eelco Dolstra
	This reverts commit 69b8f9980f39c14a59365a188b300a34d625a2cd. The timeout should be enforced remotely. Otherwise, if the garbage collector is running either locally or remotely, if will block the build or closure copying for some time. If the garbage collector takes too long, the build may time out, which is not what we want. Also, on heavily loaded systems, copying large paths to and from the remote machine can take a long time, also potentially resulting in a timeout.
2013-07-11	build-remote.pl: Move "building ..." message to a better place	Eelco Dolstra

2013-05-29	build-remote.pl: Remove meaningless signing when importing the output paths	Eelco Dolstra
	The "$UID != 0" makes no sense: if the local side has write access to the Nix store (which is always the case) then it doesn't matter if we're root - we can import unsigned paths either way.
2013-05-23	build-remote.pl: Copy all outputs in one operation	Eelco Dolstra

2013-05-23	build-remote.pl: Indicate if remote machine is refusing builds	Eelco Dolstra
	Fixes #120.
2013-05-10	build-remote.pl: Properly close the SSH connection between attempts	Eelco Dolstra

2013-05-10	build-remote.pl: Pass /dev/null as SSH's stdin	Eelco Dolstra
	Otherwise it will set the parent's stdin to non-blocking mode, causing the subsequent read of the set of inputs/outputs to fail randomly. That's insane.
2013-05-10	build-remote.pl: Allow a machine to refuse a build	Eelco Dolstra
	Before selecting a machine, build-remote.pl will try to run the command "nix-builds-inhibited" on the machine. If this command exists and returns a 0 exit code, then the machine won't be used. It's up to the user to provide this command, but it would typically be a script that checks whether there is enough disk space and whether the load is not too high.
2013-05-09	build-remote.pl: Create one process fewer on the remote side	Eelco Dolstra

2013-05-09	build-remote.pl: Enforce timeouts locally	Eelco Dolstra
	Don't pass --timeout / --max-silent-time to the remote builder. Instead, let the local Nix process terminate the build if it exceeds a timeout. The remote builder will be killed as a side-effect. This gives better error reporting (since the timeout message from the remote side wasn't properly propagated) and handles non-Nix problems like SSH hangs.
2013-03-08	Revert "Prevent config.h from being clobbered"	Eelco Dolstra
	This reverts commit 28bba8c44f484eae38e8a15dcec73cfa999156f6.
2013-03-07	Prevent config.h from being clobbered	Eelco Dolstra

2013-02-19	build-remote: Use the --quiet flag	Eelco Dolstra
	‘--option verbosity 0’ doesn't actually do anything.
2013-01-21	build-remote.pl: Don't keep build logs on the build slave	Eelco Dolstra

2012-09-12	Build hook: Pass the timeout to the remote builder	Eelco Dolstra
	Note that this will only work if the client has a very recent Nix version (post 15e1b2c223494ecb5efefc3ea0e3b926a6b1d7dc), otherwise the --option flag will just be ignored. Fixes #50.
2012-09-11	Support building a derivation if some outputs are already valid	Eelco Dolstra
	This handles the chroot and build hook cases, which are easy. Supporting the non-chroot-build case will require more work (hash rewriting!). Issue #21.
2012-04-30	Support mandatory system features in the build hook	Eelco Dolstra
	Mandatory features are features that MUST be present in a derivation's requiredSystemFeatures attribute. One application is performance testing, where we have a dedicated machine to run performance tests (and nothing else). Then we would add the label "perf" to the machine's mandatory features and to the performance testing derivations.
2012-04-24	Fix a warning in the build hook about $progressViewer	Eelco Dolstra

2012-03-05	build-remote.pl: don't wait forever for the upload lock	Eelco Dolstra
	In the build hook, don't wait forever to get the upload lock. This ensures progress if another process gets stuck while holding the upload lock.
2011-12-21	* Security: make sure the lock files used by build-remote.pl are not	Eelco Dolstra
	readable to other users. Otherwise, any user can open the lock file for reading and lock it, thus DoSing the remote build mechanism.
2011-12-21	* Use a lock to ensure that only one build-remote instance can copy a	Eelco Dolstra
	closure to a given machine at the same time. This prevents the case where multiple instances try to copy the same missing store path to the target machine, which is very wasteful.
2011-11-29	* Get rid of the shell in ssh calls.	Eelco Dolstra

2011-11-23	* Add an API function exportPaths() that provides the functionality of	Eelco Dolstra
	‘nix-store --export’. * Add a Perl module that provides the functionality of ‘nix-copy-closure --to’. This is used by build-remote.pl so it no longer needs to start a separate nix-copy-closure process. Also, it uses the Perl API to do the export, so it doesn't need to start a separate nix-store process either. As a result, nix-copy-closure and build-remote.pl should no longer fail on very large closures due to an "Argument list too long" error. (Note that having very many dependencies in a single derivation can still fail because the environment can become too large. Can't be helped though.)
2011-11-23	* build-remote.pl: drop a hard-coded reference to /nix/etc/nix.	Eelco Dolstra

2011-10-11	* Move SSH.pm.	Eelco Dolstra

2010-12-13	* nix-instantiate: return exit status 100 to denote a permanent build	Eelco Dolstra
	failure. The build hook can use this to distinguish between transient and permanent failures on the remote side.
2010-12-05	* Use CamelCase for the Perl modules.	Eelco Dolstra

2010-10-04	* Don't use SSH's `-tt' flag because it doesn't seem to work	Eelco Dolstra
	on OpenSolaris when using connection sharing. Instead have the remote side check for disconnection and kill the process group when that happens.
2010-08-31	* Always print hook output on stderr, even if --no-build-output is	Eelco Dolstra
	set. * In the build hook, print a trace message to allow Hydra to pick up the name of the remote machine used for the build.
2010-08-30	* When using the build hook, distinguish between the stderr of the	Eelco Dolstra
	hook script proper, and the stdout/stderr of the builder. Only the latter should be saved in /nix/var/log/nix/drvs. * Allow the verbosity to be set through an option. * Added a flag --quiet to lower the verbosity level.
2010-08-27	* Experimental feature: allow a derivation to tell the build hook that	Eelco Dolstra
	it requires a certain feature on the build machine, e.g. requiredSystemFeatures = [ "kvm" ]; We need this in Hydra to make sure that builds that require KVM support are forwarded to machines that have KVM support. Probably this should also be enforced for local builds.
2010-08-25	* Made the build hook mechanism more efficient. Rather than starting	Eelco Dolstra
	the hook every time we want to ask whether we can run a remote build (which can be very often), we now reuse a hook process for answering those queries until it accepts a build. So if there are N derivations to be built, at most N hooks will be started.
2010-08-25	* Don't call "cat".	Eelco Dolstra

2010-08-25	* In the build hook, temporarily register the derivation and its	Eelco Dolstra
	output as GC roots. This prevents a race if the garbage collector is running during the build.
2010-06-22	* Pass `--fallback' to the remote build to ignore failing	Eelco Dolstra
	substituters.
2010-02-04	* Doh! The scope of $slotLock should extend to the end of the script,	Eelco Dolstra
	because otherwise the lock will be released at the end of the while loop.
2010-02-04	* Typo.	Eelco Dolstra

2010-02-04	* Revert r19796 for now.	Eelco Dolstra

2010-02-03	* Respect @sysconfdir@.	Eelco Dolstra

2010-02-03	* In the build hook, if connecting to a machine fails, try the other	Eelco Dolstra
	machines of the right type (if available). This makes the build farm more robust to failures.
2010-02-03	* Use SSH connection sharing in the remote build script.	Eelco Dolstra
	* Removed the Cygwin password hack since the problem is apparently fixed in Visual Studio.
2010-01-25	* Disable gzip compression in build-remote.pl because it puts too much	Eelco Dolstra
	load on the Hydra build farm (where it's unnecessary anyway because it has a fast connection to the build machines). In any case, compression can be enabled by using the `-C' option to ssh.
2009-11-17	* Don't pass -K. It should really inherit the setting of the calling	Eelco Dolstra
	Nix though.
2009-09-17	(no commit message)	Eelco Dolstra

2009-09-17	* build-remote.pl: Pick machines in a round-robin order, rather than	Eelco Dolstra
	giving jobs to the first machine until it hits its job limit, then the second machine and so on. This should improve utilisation of the Hydra build farm a lot. Also take an optional speed factor into account to cause fast machines to be preferred over slower machines with a similar load.
2009-09-17	* build-remote.pl: allow the system type to be a comma-separated list	Eelco Dolstra
	of system types. Don't treat the x86_64-linux system type specially.
2009-04-21	* Machines of type x86_64-linux can do i686-linux builds.	Eelco Dolstra

2009-03-29	* Update the mtime on the lock file to make it easy to see when a slot	Eelco Dolstra
	was last used.
2009-03-29	* Use polling to wait for a remote build slot when using a build hook	Eelco Dolstra
	(that is, call the build hook with a certain interval until it accepts the build). * build-remote.pl was totally broken: for all system types other than the local system type, it would send all builds to the first machine of the appropriate type.
