Daniel Peebles f46e329a13 Make inputs writeable in the sandbox (builds still can’t actually write due to user permissions) 2015-01-18 23:25:29 -05:00
Shea Levy 79ca503332 Allow using /bin and /usr/bin as impure prefixes on non-darwin by default 
These directories are generally world-readable anyway, and give us the two
most common linux impurities (env and sh)

Eelco Dolstra 100961e370 Don't resolve symlinks while checking __impureHostDeps 
Since these come from untrusted users, we shouldn't do any I/O on them
before we've checked that they're in an allowed prefix.

Eelco Dolstra 27b7b94923 Set /nix/store permission to 1737 
I.e., not readable to the nixbld group. This improves purity a bit for
non-chroot builds, because it prevents a builder from enumerating
store paths (i.e. it can only access paths it knows about).

Eelco Dolstra 4acca1a5b9 Remove chatty message 
This broke building with "-vv", because the builder is not allowed to
write to stderr at this point.

Eelco Dolstra b7b6e3ddec Build derivations in a more predictable order 
Derivations are now built in order of derivation name, so a package
named "aardvark" is built before "baboon".

Fixes #399.

Eelco Dolstra 8299aaf079 Disable vacuuming the DB after garbage collection 
Especially in WAL mode on a highly loaded machine, this is not a good
idea because it results in a WAL file of approximately the same size
ad the database, which apparently cannot be deleted while anybody is
accessing it.

Eelco Dolstra b72e93bca8 Add disallowedReferences / disallowedRequisites 
For the "stdenv accidentally referring to bootstrap-tools", it seems
easier to specify the path that we don't want to depend on, e.g.

  disallowedRequisites = [ bootstrapTools ];

Eelco Dolstra 524f89f139 Use unshare() instead of clone() 
It turns out that using clone() to start a child process is unsafe in
a multithreaded program. It can cause the initialisation of a build
child process to hang in setgroups(), as seen several times in the
build farm:

The reason is that Glibc thinks that the other threads of the parent
exist in the child, so in setxid_mark_thread() it tries to get a futex
that has been acquired by another thread just before the clone(). With
fork(), Glibc runs pthread_atfork() handlers that take care of this
(in particular, __reclaim_stacks()). But clone() doesn't do that.

Fortunately, we can use fork()+unshare() instead of clone() to set up
private namespaces.

Eelco Dolstra 954188af27 Filter Nix-specific ANSI escape sequences from stderr 
The Nixpkgs stdenv prints some custom escape sequences to denote
nesting and stuff like that. Most terminals (e.g. xterm, konsole)
ignore them, but some do not (e.g. xfce4-terminal). So for the benefit
of the latter, filter them out.
