2017-04-13 Convert Settings to the new config systemEelco Dolstra1-278/+39
This makes all config options self-documenting. Unknown or unparseable config settings and --option flags now cause a warning.
2017-04-13 Merge branch 'rework-options' of https://github.com/copumpkin/nixEelco Dolstra1-34/+117
2017-03-30 Add exec primop behind allow-unsafe-native-code-during-evaluation.Shea Levy1-2/+2
Execute a given program with the (optional) given arguments as the user running the evaluation, parsing stdout as an expression to be evaluated. There are many use cases for nix that would benefit from being able to run arbitrary code during evaluation, including but not limited to: * Automatic git fetching to get a sha256 from a git revision * git rev-parse HEAD * Automatic extraction of information from build specifications from other tools, particularly language-specific package managers like cabal or npm * Secrets decryption (e.g. with nixops) * Private repository fetching Ideally, we would add this functionality in a more principled way to nix, but in the mean time 'builtins.exec' can be used to get these tasks done. The primop is only available when the 'allow-unsafe-native-code-during-evaluation' nix option is true. That flag also enables the 'importNative' primop, which is strictly more powerful but less convenient (since it requires compiling a plugin against the running version of nix).
2017-03-15 Store: Add a method for getting build logsEelco Dolstra1-1/+0
This allows various Store implementations to provide different ways to get build logs. For example, BinaryCacheStore can get the build logs from the binary cache. Also, remove the log-servers option since we can use substituters for this.
2017-03-08 Add option to disable import-from-derivation completely, even if the drv is ↵Shea Levy1-0/+2

2017-02-28 Support auto-configuration of build-max-jobsEelco Dolstra1-1/+8
"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 Dolstra1-7/+3
2017-02-22 Explicitly model all settings and fail on unrecognized onesDan Peebles1-33/+115
Previously, the Settings class allowed other code to query for string properties, which led to a proliferation of code all over the place making up new options without any sort of central registry of valid options. This commit pulls all those options back into the central Settings class and removes the public get() methods, to discourage future abuses like that. Furthermore, because we know the full set of options ahead of time, we now fail loudly if someone enters an unrecognized option, thus preventing subtle typos. With some template fun, we could probably also dump the full set of options (with documentation, defaults, etc.) to the command line, but I'm not doing that yet here.
2017-02-16 Move netrcFile to SettingsEelco Dolstra1-19/+17
Also get rid of Settings::processEnvironment(), it appears to be useless.
2017-02-08 Include config.h implicitly with '-include config.h' in CFLAGSTuomas Tynkkynen1-2/+0
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.

2016-11-26 Revert "Get rid of unicode quotes (#1140)"Eelco Dolstra1-3/+3
This reverts commit f78126bfd6b6c8477fcdbc09b2f98772dbe9a1e7. There really is no need for such a massive change...

2016-08-13 remove old traces of resolve-system-dependenciesJude Taylor1-1/+1
2016-08-10 Remove $NIX_DB_DIREelco Dolstra1-1/+0
This variable has no reason to exist, given $NIX_STATE_DIR.
2016-04-29 Eliminate the substituter mechanismEelco Dolstra1-13/+0
Substitution is now simply a Store -> Store copy operation, most typically from BinaryCacheStore to LocalStore.
2016-04-25 Show the log tail when a build failsEelco Dolstra1-1/+0
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.
2016-04-25 Remove --print-build-traceEelco Dolstra1-1/+0
This was added to support Hydra, but Hydra no longer uses it.
2016-04-11 Remove manifest supportEelco Dolstra1-1/+0
Manifests have been superseded by binary caches for years. This also gets rid of nix-pull, nix-generate-patches and bsdiff/bspatch.
2016-04-08 Remove failed build cachingEelco Dolstra1-2/+0
This feature was implemented for Hydra, but Hydra no longer uses it.

Issue #564.
2015-04-18 Add the pre-build hook.Shea Levy1-0/+1
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.
2015-04-18 Revert "Add the pre-build hook."Shea Levy1-1/+0
Going to reimplement differently. This reverts commit 1e4a4a2e9fc382f47f58b448f3ee034cdd28218a.

2015-04-09 Implement a TTL on cached fetchurl/fetchTarball resultsEelco Dolstra1-0/+8
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.
2015-02-23 Use chroots for all derivationsEelco Dolstra1-2/+0
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.
2014-09-17 Settings: Add bool get()Eelco Dolstra1-0/+8
2014-08-20 Use proper quotes everywhereEelco Dolstra1-3/+3

2014-08-04 Add option ‘build-extra-chroot-dirs’Eelco Dolstra1-4/+0
This is useful for extending (rather than overriding) the default set of chroot paths.
2014-08-04 Make chroot builds easier to set upEelco Dolstra1-0/+3
By default, we now include /bin/sh as a bind-mount of bash.
2014-07-25 nix-daemon: Pass on the user's $SSH_AUTH_SOCK to the SSH substituterEelco Dolstra1-0/+8
2014-07-25 Change the default for use-ssh-substituter to ‘true’Eelco Dolstra1-2/+2
Now you only have to pass ‘--option ssh-substituter-hosts nix-ssh@bla’ to enable SSH substitution.
2014-07-19 Revert old useBuildHook behaviourEelco Dolstra1-1/+1
2014-07-17 nix-daemon: Add trusted-users and allowed-users optionsEelco Dolstra1-0/+4
‘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.
2014-07-16 Handle case collisions on case-insensitive systemsEelco Dolstra1-0/+2
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.

2014-06-24 Only add the importNative primop if the ↵Shea Levy1-0/+2
allow-arbitrary-code-during-evaluation option is true (default false)
2014-05-21 nix-store -l: Fetch build logs from the InternetEelco Dolstra1-0/+1
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.
2014-05-02 Set build-max-jobs to the number of available cores by defaultEelco Dolstra1-0/+5
More zero configuration.
2014-05-02 When running as root, use build users by defaultEelco Dolstra1-0/+1
This removes the need to have a nix.conf, and prevents people from accidentally running Nix builds as root.
2014-02-27 Set up a private /dev/pts in the chrootEelco Dolstra1-1/+0
2014-02-27 Set up a minimal /dev in chrootsEelco Dolstra1-1/+0
Not bind-mounting the /dev from the host also solves the problem with /dev/shm being a symlink to something not in the chroot.
