2015-01-02Allow $NIX_PAGER to override $PAGEREelco Dolstra
2014-12-14PedantryEelco Dolstra
2014-12-14Merge branch 'cygwin-master' of https://github.com/ternaris/nixEelco Dolstra
2014-12-12Don't abort if we get a signal while waiting for the pagerEelco Dolstra
2014-12-10Provide default pagersEelco Dolstra
Borrowed from systemd.
2014-12-10Revert "Use posix_spawn to run the pager"Eelco Dolstra
This reverts commit d34d2b2bbf784c0bb420a50905af25e02c6e4989.

2014-12-05Use posix_spawn to run the pagerEelco Dolstra
In low memory environments, "nix-env -qa" failed because the fork to run the pager hit the kernel's overcommit limits. Using posix_spawn gets around this. (Actually, you have to use posix_spawn with the undocumented POSIX_SPAWN_USEVFORK flag, otherwise it just uses fork/exec...)
2014-10-14Remove redundant space in usage errorsEelco Dolstra
2014-09-26printMissing(): Print derivations in approximate build orderEelco Dolstra
2014-08-20Flush std::cout before closing stdoutEelco Dolstra
2014-08-20Provide reasonable default flags for $LESSEelco Dolstra
Borrowed from systemd.
2014-08-20Use proper quotes everywhereEelco Dolstra
2014-08-20Add some colorEelco Dolstra
2014-08-20nix-store -l: Automatically pipe output into $PAGEREelco Dolstra
2014-08-13Handle compound single dash options properlyEelco Dolstra
So now nix-instantiate --eval -E '{x}: x' --argstr x -xyzzy correctly prints "-xyzzy", rather than giving an error. Issue NixOS/hydra#176.
2014-08-13Refactor option handlingEelco Dolstra
2014-08-13Remove pointless NIX_LOG_TYPE environment variableEelco Dolstra
2014-07-31Restore default SIGPIPE handler before invoking ‘man’Eelco Dolstra
Fixes NixOS/nixpkgs#3410.
2014-05-23Ugly hack to allow --argstr values starting with a dashEelco Dolstra
Fixes #265.
2014-03-29restoreSIGPIPE(): Fill in sa_maskEelco Dolstra
Issue #231.
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>

2013-12-20nix-shell: Don't warn about the lack of a GC rootEelco Dolstra
2013-11-23Drop the dependency on libgc in libmainEelco Dolstra
Instead, libexpr now depends on libgc. This means commands like nix-store that don't do any evaluation no longer require libgc.
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.
2013-10-02Report OOM errors betterEelco Dolstra
2013-07-30Detect stack overflowsEelco Dolstra
Previously, if the Nix evaluator gets a stack overflow due to a deep or infinite recursion in the Nix expression, the user gets an unhelpful message ("Segmentation fault") that doesn't indicate that the problem is in the user's code rather than Nix itself. Now it prints: error: stack overflow (possible infinite recursion) This only works on x86_64-linux and i686-linux. Fixes #35.
2013-03-08Revert "Prevent config.h from being clobbered"Eelco Dolstra
This reverts commit 28bba8c44f484eae38e8a15dcec73cfa999156f6.
2013-03-07Prevent config.h from being clobberedEelco Dolstra
2013-02-19build-remote: Use the --quiet flagEelco Dolstra
‘--option verbosity 0’ doesn't actually do anything.
2012-12-11On SQLITE_BUSY, wait a random amount of timeEelco Dolstra
If all contending processes wait a fixed amount of time (100 ms), there is a good probability that they'll just collide again.
2012-11-27Add builtin constants ‘langVersion’ and ‘nixVersion’Eelco Dolstra
The integer constant ‘langVersion’ denotes the current language version. It gets increased every time a language feature is added/changed/removed. It's currently 1. The string constant ‘nixVersion’ contains the current Nix version, e.g. "1.2pre2980_9de6bc5".
2012-11-20nix-store -r: Add ‘--ignore-unknown’ flagEelco Dolstra
This flag causes paths that do not have a known substitute to be quietly ignored. This is mostly useful for Charon, allowing it to speed up deployment by letting a machine use substitutes for all substitutable paths, instead of uploading them. The latter is frequently faster, e.g. if the target machine has a fast Internet connection while the source machine is on a slow ADSL line.
2012-10-03Drop support for running nix-worker in "slave" modeEelco Dolstra
AFAIK nobody uses this, setuid binaries are evil, and there is no good reason why people can't just run the daemon.
2012-10-03When ‘--help’ is given, just run ‘man’ to show the manual pageEelco Dolstra
I.e. do what git does. I'm too lazy to keep the builtin help text up to date :-) Also add ‘--help’ to various commands that lacked it (e.g. nix-collect-garbage).
2012-08-27Merge branch 'master' into no-manifestsEelco Dolstra
2012-08-24Include the output name in the GC root linkEelco Dolstra
Output names are now appended to resulting GC symlinks, e.g. by nix-build. For backwards compatibility, if the output is named "out", nothing is appended. E.g. doing "nix-build -A foo" on a derivation that produces outputs "out", "bin" and "dev" will produce symlinks "./result", "./result-bin" and "./result-dev", respectively.
2012-07-31Add an option ‘build-fallback’ (equivalent to the --fallback flag)Eelco Dolstra
2012-07-30Refactor settings processingEelco Dolstra
Put all Nix configuration flags in a Settings object.
2012-07-30WhitespaceEelco Dolstra
2012-03-13Ensure that Perl processes delete their entry in the temproots directoryEelco Dolstra
By moving the destructor object to libstore.so, it's also run when download-using-manifests and nix-prefetch-url exit. This prevents them from cluttering /nix/var/nix/temproots with stale files.
2012-03-05nix-worker: put the pid of the caller in argv[1]Eelco Dolstra
This is useful for debugging.
2011-12-14* Remove the terminate handler, which was only really needed becauseEelco Dolstra
of Berkeley DB (see r8632).
2011-11-29* Get rid of some superfluous error messages if a substituter fails.Eelco Dolstra
* Say "fetch" instead of "substitute".
2011-11-22* Move initialisation of variables like nixConfDir from libmain toEelco Dolstra
libstore so that the Perl bindings can use it as well. It's vital that the Perl bindings use the configuration file, because otherwise nix-copy-closure will fail with a ‘database locked’ message if the value of ‘use-sqlite-wal’ is changed from the default.
2011-09-06* Added a command ‘nix-store --verify-paths PATHS’ to check whetherEelco Dolstra
the contents of any of the given store paths have been modified. E.g. $ nix-store --verify-path $(nix-store -qR /var/run/current-system) path `/nix/store/m2smyiwbxidlprfxfz4rjlvz2c3mg58y-etc' was modified! expected hash `fc87e271c5fdf179b47939b08ad13440493805584b35e3014109d04d8436e7b8', got `20f1a47281b3c0cbe299ce47ad5ca7340b20ab34246426915fce0ee9116483aa' All paths are checked; the exit code is 1 if any path has been modified, 0 otherwise.
2011-08-31* Eliminate all uses of the global variable ‘store’ from libstore.Eelco Dolstra
This should also fix: nix-instantiate: ./../boost/shared_ptr.hpp:254: T* boost::shared_ptr<T>::operator->() const [with T = nix::StoreAPI]: Assertion `px != 0' failed. which was caused by hashDerivationModulo() calling the ‘store’ object (during store upgrades) before openStore() assigned it.
2011-06-30Add support for the `build-timeout' and `--timeout' options.Ludovic Courtès
