MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This is a squashed commit of the following: commit 0dccab9f417b406f5d4aedc81900fc7b2f16c9f6 Author: Eelco Dolstra Date: Thu Jul 2 00:30:16 2015 +0200 Typo commit 2cd28517b13524c242c7758783b0b2d8250fdded Author: Ludovic Courtès Date: Wed Jul 1 14:56:34 2015 +0200 Preserve supplementary groups of build users The following patch is an attempt to address this bug (see ) by preserving the supplementary groups of build users in the build environment. In practice, I would expect that supplementary groups would contain only one or two groups: the build users group, and possibly the “kvm” group.

For instance, if we can't substitute a fetchgit call, then we have to download/build git and all its dependencies. Partially reverts 5558652709f27e8a887580b77b93c705659d7a4b and adds a new derivation attribute "allowSubstitutes" to specify whether a derivation may be substituted. --- nix/libutil/util.cc | 11 +++++------ nix/libutil/util.hh | 2 +- 2 files changed, 6 insertions(+), 7 deletions(-) (limited to 'nix/libutil') diff --git a/nix/libutil/util.cc b/nix/libutil/util.cc index dab4235b04..14026ab829 100644 --- a/nix/libutil/util.cc +++ b/nix/libutil/util.cc @@ -897,10 +897,10 @@ pid_t startProcess(std::function fun, } -std::vector stringsToCharPtrs(const Strings & ss) +std::vector stringsToCharPtrs(const Strings & ss) { - std::vector res; - for (auto & s : ss) res.push_back(s.c_str()); + std::vector res; + for (auto & s : ss) res.push_back((char *) s.c_str()); res.push_back(0); return res; } @@ -921,12 +921,11 @@ string runProgram(Path program, bool searchPath, const Strings & args) Strings args_(args); args_.push_front(program); - auto cargs = stringsToCharPtrs(args_); if (searchPath) - execvp(program.c_str(), (char * *) &cargs[0]); + execvp(program.c_str(), stringsToCharPtrs(args_).data()); else - execv(program.c_str(), (char * *) &cargs[0]); + execv(program.c_str(), stringsToCharPtrs(args_).data()); throw SysError(format("executing `%1%'") % program); }); diff --git a/nix/libutil/util.hh b/nix/libutil/util.hh index 6a84ed8851..24e16ba36a 100644 --- a/nix/libutil/util.hh +++ b/nix/libutil/util.hh @@ -284,7 +284,7 @@ MakeError(ExecError, Error) /* Convert a list of strings to a null-terminated vector of char *'s.
