2017-02-28Support auto-configuration of build-max-jobsEelco Dolstra
"build-max-jobs" and the "-j" option can now be set to "auto" to use the number of CPUs in the system. (Unlike build-cores, it doesn't use 0 to imply auto-configuration, because a) magic values are a bad idea in general; b) 0 is a legitimate value used to disable local building.) Fixes #1198.
2017-02-27_SC_NPROCESSORS_ONLN -> std::thread::hardware_concurrency()Eelco Dolstra
2017-02-16Move netrcFile to SettingsEelco Dolstra
Also get rid of Settings::processEnvironment(), it appears to be useless.
2017-02-08Include config.h implicitly with '-include config.h' in CFLAGSTuomas Tynkkynen
Because config.h can #define things like _FILE_OFFSET_BITS=64 and not every compilation unit includes config.h, we currently compile half of Nix with _FILE_OFFSET_BITS=64 and other half with _FILE_OFFSET_BITS unset. This causes major havoc with the Settings class on e.g. 32-bit ARM, where different compilation units disagree with the struct layout.

2016-11-26Revert "Get rid of unicode quotes (#1140)"Eelco Dolstra
This reverts commit f78126bfd6b6c8477fcdbc09b2f98772dbe9a1e7. There really is no need for such a massive change...
2016-11-25Get rid of unicode quotes (#1140)Guillaume Maudoux
2016-10-27Add nix.conf options for -k and -KShea Levy
Fixes #1084
2016-08-13remove old traces of resolve-system-dependenciesJude Taylor
2016-08-10Remove $NIX_DB_DIREelco Dolstra
This variable has no reason to exist, given $NIX_STATE_DIR.
2016-04-29Eliminate the substituter mechanismEelco Dolstra
Substitution is now simply a Store -> Store copy operation, most typically from BinaryCacheStore to LocalStore.
2016-04-25Show the log tail when a build failsEelco Dolstra
If --no-build-output is given (which will become the default for the "nix" command at least), show the last 10 lines of the build output if the build fails.
2016-04-25Remove --print-build-traceEelco Dolstra
This was added to support Hydra, but Hydra no longer uses it.
2016-04-11Remove manifest supportEelco Dolstra
Manifests have been superseded by binary caches for years. This also gets rid of nix-pull, nix-generate-patches and bsdiff/bspatch.
2016-04-08Remove failed build cachingEelco Dolstra
This feature was implemented for Hydra, but Hydra no longer uses it.

Issue #564.
2015-04-18Add the pre-build hook.Shea Levy
This hook can be used to set system-specific per-derivation build settings that don't fit into the derivation model and are too complex or volatile to be hard-coded into nix. Currently, the pre-build hook can only add chroot dirs/files through the interface, but it also has full access to the chroot root. The specific use case for this is systems where the operating system ABI is more complex than just the kernel-support system calls. For example, on OS X there is a set of system-provided frameworks that can reliably be accessed by any program linked to them, no matter the version the program is running on. Unfortunately, those frameworks do not necessarily live in the same locations on each version of OS X, nor do their dependencies, and thus nix needs to know the specific version of OS X currently running in order to make those frameworks available. The pre-build hook is a perfect mechanism for doing just that.
2015-04-18Revert "Add the pre-build hook."Shea Levy
Going to reimplement differently. This reverts commit 1e4a4a2e9fc382f47f58b448f3ee034cdd28218a.

2015-04-09Implement a TTL on cached fetchurl/fetchTarball resultsEelco Dolstra
This is because we don't want to do HTTP requests on every evaluation, even though we can prevent a full redownload via the cached ETag. The default is one hour.
2015-02-23Use chroots for all derivationsEelco Dolstra
If ‘build-use-chroot’ is set to ‘true’, fixed-output derivations are now also chrooted. However, unlike normal derivations, they don't get a private network namespace, so they can still access the network. Also, the use of the ‘__noChroot’ derivation attribute is no longer allowed. Setting ‘build-use-chroot’ to ‘relaxed’ gives the old behaviour.
2014-09-17Settings: Add bool get()Eelco Dolstra
2014-08-20Use proper quotes everywhereEelco Dolstra
2014-08-04Move some options out of globalsEelco Dolstra
2014-08-04RefactorEelco Dolstra
2014-08-04Add option ‘build-extra-chroot-dirs’Eelco Dolstra
This is useful for extending (rather than overriding) the default set of chroot paths.
2014-08-04Make chroot builds easier to set upEelco Dolstra
By default, we now include /bin/sh as a bind-mount of bash.
2014-07-25nix-daemon: Pass on the user's $SSH_AUTH_SOCK to the SSH substituterEelco Dolstra
2014-07-25Change the default for use-ssh-substituter to ‘true’Eelco Dolstra
Now you only have to pass ‘--option ssh-substituter-hosts nix-ssh@bla’ to enable SSH substitution.
2014-07-19Revert old useBuildHook behaviourEelco Dolstra
2014-07-17nix-daemon: Add trusted-users and allowed-users optionsEelco Dolstra
‘trusted-users’ is a list of users and groups that have elevated rights, such as the ability to specify binary caches. It defaults to ‘root’. A typical value would be ‘@wheel’ to specify all users in the wheel group. ‘allowed-users’ is a list of users and groups that are allowed to connect to the daemon. It defaults to ‘*’. A typical value would be ‘@users’ to specify the ‘users’ group.
2014-07-16Handle case collisions on case-insensitive systemsEelco Dolstra
When running NixOps under Mac OS X, we need to be able to import store paths built on Linux into the local Nix store. However, HFS+ is usually case-insensitive, so if there are directories with file names that differ only in case, then importing will fail. The solution is to add a suffix ("~nix~case~hack~<integer>") to colliding files. For instance, if we have a directory containing xt_CONNMARK.h and xt_connmark.h, then the latter will be renamed to "xt_connmark.h~nix~case~hack~1". If a store path is dumped as a NAR, the suffixes are removed. Thus, importing and exporting via a case-insensitive Nix store is round-tripping. So when NixOps calls nix-copy-closure to copy the path to a Linux machine, you get the original file names back. Closes #119.
2014-07-11Allow $NIX_BUILD_HOOK to be relative to Nix libexec directoryEelco Dolstra
2014-06-27allow-arbitrary-code-during-evaluation -> ↵Eelco Dolstra
allow-unsafe-native-code-during-evaluation
2014-06-24Only add the importNative primop if the ↵Shea Levy
allow-arbitrary-code-during-evaluation option is true (default false)
2014-05-21nix-store -l: Fetch build logs from the InternetEelco Dolstra
If a build log is not available locally, then ‘nix-store -l’ will now try to download it from the servers listed in the ‘log-servers’ option in nix.conf. For instance, if you have: log-servers = http://hydra.nixos.org/log then it will try to get logs from http://hydra.nixos.org/log/<base name of the store path>. So you can do things like: $ nix-store -l $(which xterm) and get a log even if xterm wasn't built locally.
2014-05-02Set build-max-jobs to the number of available cores by defaultEelco Dolstra
More zero configuration.
2014-05-02When running as root, use build users by defaultEelco Dolstra
This removes the need to have a nix.conf, and prevents people from accidentally running Nix builds as root.
2014-02-27Set up a private /dev/pts in the chrootEelco Dolstra
2014-02-27Set up a minimal /dev in chrootsEelco Dolstra
Not bind-mounting the /dev from the host also solves the problem with /dev/shm being a symlink to something not in the chroot.
2014-02-26Only start download-via-ssh if it's enabledEelco Dolstra
2014-02-26Add use-ssh-substituter setting.Shea Levy
It defaults to false and can be overridden by RemoteStore. Untested currently, just quickly put this together
2014-02-14Minor style fixesEelco Dolstra

2014-02-08Add download-via-ssh substituterShea Levy
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>
2013-11-22Drop the dependency on AutomakeEelco Dolstra
2013-11-12Make function calls show up in stack traces againEelco Dolstra
Note that adding --show-trace prevents functions calls from being tail-recursive, so an expression that evaluates without --show-trace may fail with a stack overflow if --show-trace is given.
2013-09-06Don't apply the CPU affinity hack to nix-shell (and other Perl programs)Eelco Dolstra
As discovered by Todd Veldhuizen, the shell started by nix-shell has its affinity set to a single CPU. This is because nix-shell connects to the Nix daemon, which causes the affinity hack to be applied. So we turn this off for Perl programs.
