2012-07-30Refactor settings processingEelco Dolstra
Put all Nix configuration flags in a Settings object.
2012-07-17Add function queryPathFromHashPart()Eelco Dolstra
To implement binary caches efficiently, Hydra needs to be able to map the hash part of a store path (e.g. "gbg...zr7") to the full store path (e.g. "/nix/store/gbg...kzr7-subversion-1.7.5"). (The binary cache mechanism uses hash parts as a key for looking up store paths to ensure privacy.) However, doing a search in the Nix store for /nix/store/<hash>* is expensive since it requires reading the entire directory. queryPathFromHashPart() prevents this by doing a cheap database lookup.
2012-07-17queryPathInfo(): return hash in base-32 if desiredEelco Dolstra
Cherry-picked from the no-manifests branch.
2012-03-19Add a command "nix-build --run-env" to reproduce the environment of a derivationEelco Dolstra
This command builds or fetches all dependencies of the given derivation, then starts a shell with the environment variables from the derivation. This shell also sources $stdenv/setup to initialise the environment further. The current directory is not changed. Thus this is a convenient way to reproduce a build environment in an existing working tree. Existing environment variables are left untouched (unless the derivation overrides them). As a special hack, the original value of $PATH is appended to the $PATH produced by $stdenv/setup. Example session: $ nix-build --run-env '<nixpkgs>' -A xterm (the dependencies of xterm are built/fetched...) $ tar xf $src $ ./configure $ make $ emacs (... hack source ...) $ make $ ./xterm
2011-12-02* Add some more functions to the Perl bindings.Eelco Dolstra
2011-11-29* download-using-manifests: use the Perl bindings.Eelco Dolstra
2011-11-29* For consistency with "nix-store -q --hash", produce hashes inEelco Dolstra
base-32. (This affects Hydra manifests.)
2011-11-23* Add an API function exportPaths() that provides the functionality ofEelco 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.)
2011-11-22* 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.
2011-10-11* Use the Store API bindings in nix-copy-closure.Eelco Dolstra
2011-10-10* Include the Nix Perl bindings in Nix itself. This will allow theEelco Dolstra
bindings to be used in Nix's own Perl scripts. The only downside is that Perl XS and Automake/libtool don't really like each other, so building is a bit tricky.
