Nathan Zadoks c6beaf5708 Handle ARM triples without an endianness suffix
Alpine seems to use this, and it results in a wrong
builtins.currentSystem. Big-endian ARM systems have triples starting
with armv6eb- or armv7eb-, so this doesn't change any systems that
already worked.

Eelco Dolstra ef7c2d8b3e Revert "Do not override environment CFLAGS and CXXFLAGS"
This reverts commit 80ebd60e7c. The
reason why we cleared CFLAGS/CXXFLAGS was because otherwise we get a
default value of -O2, which interferes with the defaults set in the
Makefile. (E.g. "make OPTIMIZE=0" should not pass -O2.)

Ilya Novoselov 80ebd60e7c Do not override environment CFLAGS and CXXFLAGS
Looks like 5a05cf4063 removed usage of
environment CFLAGS and CXXFLAGS by mistake. That change broke building
of nix on fedora core 23.

Harald van Dijk 5451b8db9d Use pivot_root in addition to chroot when possible
chroot only changes the process root directory, not the mount namespace root
directory, and it is well-known that any process with chroot capability can
break out of a chroot "jail". By using pivot_root as well, and unmounting the
original mount namespace root directory, breaking out becomes impossible.

Non-root processes typically have no ability to use chroot() anyway, but they
can gain that capability through the use of clone() or unshare(). For security
reasons, these syscalls are limited in functionality when used inside a normal
chroot environment. Using pivot_root() this way does allow those syscalls to be
put to their full use.

Eelco Dolstra 1c972cba14 Make libsodium an optional dependency 2015-02-10 11:54:06 +01:00
Eelco Dolstra e0def5bc4b Use libsodium instead of OpenSSL for binary cache signing
Sodium's Ed25519 signatures are much shorter than OpenSSL's RSA
signatures. Public keys are also much shorter, so they're now
specified directly in the nix.conf option ‘binary-cache-public-keys’.

The new command ‘nix-store --generate-binary-cache-key’ generates and
prints a public and secret key.

Eelco Dolstra a583a2bc59 Run the daemon worker on the same CPU as the client
On a system with multiple CPUs, running Nix operations through the
daemon is significantly slower than "direct" mode:

$ NIX_REMOTE= nix-instantiate '<nixos>' -A system
real    0m0.974s
user    0m0.875s
sys     0m0.088s

$ NIX_REMOTE=daemon nix-instantiate '<nixos>' -A system
real    0m2.118s
user    0m1.463s
sys     0m0.218s

The main reason seems to be that the client and the worker get moved
to a different CPU after every call to the worker.  This patch adds a
hack to lock them to the same CPU.  With this, the overhead of going
through the daemon is very small:

$ NIX_REMOTE=daemon nix-instantiate '<nixos>' -A system
real    0m1.074s
user    0m0.809s
sys     0m0.098s

Shea Levy 2c9cf50746 makeStoreWritable: Use statvfs instead of /proc/self/mountinfo to find out if /nix/store is a read-only bind mount
/nix/store could be a read-only bind mount even if it is / in its own filesystem, so checking the 4th field in mountinfo is insufficient.

Eelco Dolstra f794465ca8 Disable use of vfork()
vfork() is just too weird.  For instance, in this build:

  http://hydra.nixos.org/build/3330487

the value fromHook.writeSide becomes corrupted in the parent, even
though the child only reads from it.  At -O0 the problem goes away.
Probably the child is overriding some spilled temporary variable.

If I get bored I may implement using posix_spawn() instead.

Eelco Dolstra ea89df2b76 Use vfork() instead of fork() if available
Hopefully this reduces the chance of hitting ‘unable to fork: Cannot

Eelco Dolstra 4911a10a4e Use XZ compression in binary caches
XZ compresses significantly better than bzip2.  Here are the
compression ratios and execution times (using 4 cores in parallel) on
my /var/run/current-system (3.1 GiB):

  bzip2: total compressed size 849.56 MiB, 30.8% [2m08]
  xz -6: total compressed size 641.84 MiB, 23.4% [6m53]
  xz -7: total compressed size 621.82 MiB, 22.6% [7m19]
  xz -8: total compressed size 599.33 MiB, 21.8% [7m18]
  xz -9: total compressed size 588.18 MiB, 21.4% [7m40]

Note that compression takes much longer.  More importantly, however,
decompression is much faster:

  bzip2: 1m47.274s
  xz -6: 0m55.446s
  xz -7: 0m54.119s
  xz -8: 0m52.388s
  xz -9: 0m51.842s

The only downside to using -9 is that decompression takes a fair
amount (~65 MB) of memory.

Eelco Dolstra d03a295192 Require SQLite >= 3.6.19
Nix needs SQLite's foreign key constraint feature, which was
introduced in 3.6.19.  Without it, the database won't be cleaned up
correctly when paths are deleted.  See
e.g. http://hydra.nixos.org/build/2494142.

Eelco Dolstra b006a31d52 Drop the externals directory
Nix now requires SQLite and bzip2 to be pre-installed.  SQLite is

depending on SQLite is not a big problem.

The --with-bzip2, --with-openssl and --with-sqlite flags are gone.

Eelco Dolstra bd013b6f98 On Linux, make the Nix store really read-only by using the immutable bit
I was bitten one time too many by Python modifying the Nix store by
creating *.pyc files when run as root.  On Linux, we can prevent this
by setting the immutable bit on files and directories (as in ‘chattr
+i’).  This isn't supported by all filesystems, so it's not an error
if setting the bit fails.  The immutable bit is cleared by the garbage
collector before deleting a path.  The only tricky aspect is in
optimiseStore(), since it's forbidden to create hard links to an
immutable file.  Thus optimiseStore() temporarily clears the immutable
bit before creating the link.

Eelco Dolstra 5c5ab2bc12 * Don't link against pthreads. This was added way back in r211
because Berkeley DB needed it on some platforms, but we don't use
  BDB anymore.

  On FreeBSD, if you link against pthreads, then the main thread gets
  a 2 MB stack which cannot be overriden (it ignores "ulimit -s"):

    http://www.mail-archive.com/freebsd-hackers@freebsd.org/msg62445.html
  
  This is not enough for Nix.  For instance, the garbage collector can
  fail if there is a pathologically deep chain of references
  (http://hydra.nixos.org/build/556199).  2 MB is also not enough for
  many Nix expressions.
  
  Arguably the garbage collector shouldn't use recursion, because in
  NixOS unprivileged users can DOS the garbage collector by creating a
  sufficiently deeply nested chain of references.  But getting rid of
  recursion is a bit harder.

Eelco Dolstra d7875d1648 * Use SQLite 3.7.0.1. 2010-08-06 07:51:27 +00:00
Eelco Dolstra 587dc8aa00 * Sync with the trunk. 2010-08-04 17:48:29 +00:00
Eelco Dolstra fd9c77dfc7 * Use SQLite 3.7.0's write-ahead logging (WAL mode). This is a lot
faster than the old mode when fsyncs are enabled, because it only
  performs an fsync() when doing a checkpoint, rather than at every
  commit.  Some timings for doing a "nix-instantiate /etc/nixos/nixos
  -A system" after modifying the stdenv setup script:

    42.5s - SQLite 3.6.23 with truncate mode and fsync
     3.4s - SQLite 3.6.23 with truncate mode and no fsync
    32.1s - SQLite 3.7.0 with truncate mode and fsync
    16.8s - SQLite 3.7.0 with WAL mode and fsync, auto-checkpoint
            every 1000 pages
     8.3s - SQLite 3.7.0 with WAL mode and fsync, auto-checkpoint
            every 8192 pages
     1.7s - SQLite 3.7.0 with WAL mode and no fsync

  The default is now to use WAL mode with fsyncs.  Because WAL doesn't
  work on remote filesystems such as NFS (as it uses shared memory),
  truncate mode can be re-enabled by setting the "use-sqlite-wal"
  option to false.

Eelco Dolstra f71ea9c911 * Use SQLite 3.6.23. 2010-03-23 10:38:59 +00:00
Lluís Batlle i Rossell 13cce8ec45 Making 'bin2c' to be built with the compiler for the local system.
I copied the configure.ac code about CC_FOR_BUILD from libX11.
2010-03-11 20:56:25 +00:00
Eelco Dolstra 070057c1b9 * Sync with the trunk. 2010-03-11 10:52:52 +00:00
Eelco Dolstra 05fbf61f0e * nix-prefetch-url depends on sed (see
http://hydra.nixos.org/build/311170).
2010-03-05 18:26:47 +00:00
Eelco Dolstra d8c5745c41 * Support static builds. 2010-03-02 17:12:47 +00:00
Eelco Dolstra 5414b3b2db * Remove the --enable-static-nix flag. 2010-03-02 16:40:40 +00:00
Eelco Dolstra 594eaddd11 * When using the included sqlite/aterm libraries, build with
--enable-shared.
* In libutil/libstore/libexpr etc., link against sqlite and aterm.
* Some more header file hygiene.
2010-03-02 15:58:13 +00:00
Eelco Dolstra 84a4dd5ff0 * Don't use fdatasync since it doesn't work on Snow Leopard.
* Don't refer to config.h in util.hh, because config.h is not
  installed (http://hydra.nixos.org/build/303053).
2010-02-24 15:46:06 +00:00
Eelco Dolstra fae0427324 * ADDITIONAL_NETWORK_LIBS -> LIBS. 2010-02-24 12:25:48 +00:00
Eelco Dolstra 5954eadf67 * Remove the fdatasync check since it's no longer needed. 2010-02-24 12:16:50 +00:00
Eelco Dolstra b4e6d98fc3 * configure: flag --with-sqlite. 2010-02-23 22:12:46 +00:00
Eelco Dolstra c1a07f9445 * Convert the Nix database to SQLite. 2010-02-18 13:16:59 +00:00
Eelco Dolstra 2723d9b56e * If fdatasync() isn't available, use fsync(). 2010-02-02 11:57:49 +00:00
Eelco Dolstra 327a232c85 * Remove support for old (before Nix 0.12pre12020) databases. 2009-11-06 01:15:44 +00:00
Sander van der Burg 53a4981fa2 Added optional parameter which adds -lnsl -lsocket to make the Nix package manager work on OpenSolaris 2009-10-08 14:50:37 +00:00
Peter Simons 18f0ff003d configure.ac: use AC_SYS_LARGEFILE to determine how to enable 64-bit file size support
Defining -D_FILE_OFFSET_BITS=64 works on most platforms, but not on all (i.e.
Solaris). Also, the Autoconf macro offers the user a switch to disable the
functionality in case of problems.
2009-10-06 09:14:06 +00:00
Eelco Dolstra 51ad64cc07 * Use xmllint (>= 2.7.4) for RelaxNG validation instead of Jing. 2009-09-18 11:45:56 +00:00
Eelco Dolstra 6a5599fd01 * Typo. 2009-05-07 11:33:57 +00:00
Eelco Dolstra 9856efc7b0 * Support doing a fully static build. Statically linked Nix binaries
will be useful as a fallback on platforms for which there are no
  RPMs/Debs available.
2009-03-26 12:22:08 +00:00
Eelco Dolstra 77d272623f * NAR archives: handle files larger than 2^32 bytes. Previously it
would just silently store only (fileSize % 2^32) bytes.
* Use posix_fallocate if available when unpacking archives.
* Provide a better error message when trying to unpack something that
  isn't a NAR archive.
2009-03-22 17:36:43 +00:00
Eelco Dolstra be88248add * Make the version available to release.nix. 2009-03-09 15:05:08 +00:00
Eelco Dolstra c504d90c11 * Support i686-linux builds directly on x86_64-linux Nix
installations.  This is implemented using the personality() syscall,
  which causes uname to return "i686" in child processes.
2009-01-12 16:30:32 +00:00
Eelco Dolstra ac36c6cd44 * Some hackery to make "make check" succeed on Cygwin. 2008-12-12 15:36:18 +00:00
Eelco Dolstra 2b70a8e7c9 * Detect whether unshare() is available. 2008-12-12 13:41:36 +00:00
Eelco Dolstra 7c54f1603f * Do chroot builds in a private namespace. This means that all the
bind-mounts we do are only visible to the builder process and its
  children.  So accidentally doing "rm -rf" on the chroot directory
  won't wipe out /nix/store and other bind-mounted directories
  anymore.  Also, the bind-mounts in the private namespace disappear
  automatically when the builder exits.
2008-12-11 17:00:12 +00:00
Eelco Dolstra 5d4eb9dd07 * Moved the build farm job for building Nix to the Nix tree. 2008-11-26 01:13:29 +00:00
Eelco Dolstra 2ab09a55cf * Bump the version number. 2008-11-20 21:51:58 +00:00
Eelco Dolstra 285d26374a * Don't set the prefix to /nix by default, rather use the Autoconf
default of /usr/local.  However, localstatedir and storedir are set
  to /nix/var/nix and /nix/store respectively unless they're
  explicitly overriden.
2008-11-20 14:14:35 +00:00
Eelco Dolstra b0e92f6d47 * Merged the no-bdb branch (-r10900:HEAD
https://svn.nixos.org/repos/nix/nix/branches/no-bdb).
2008-06-09 13:52:45 +00:00
Michael Raskin b4bc8b7616 --proxy=proxy:3128 2008-05-07 14:18:28 +00:00
Eelco Dolstra 658816ddc9 * Make really sure that we use bash. The line
NEED_PROG(shell, bash)

  actually uses the content of $shell if set, which often points at
  /bin/sh.
2008-04-10 09:54:23 +00:00
Eelco Dolstra 895c953817 * Bumped the version number to 0.12. 2007-12-31 17:53:59 +00:00
Eelco Dolstra df303666bc * Use strsignal if available to give better error messages for
builders that fail due to a signal.
2007-12-14 14:49:35 +00:00
Eelco Dolstra 5f8a203b55 * A rule to make a PDF version of the manual. 2007-11-01 14:42:44 +00:00
Eelco Dolstra 0b95603595 * Depend on bash instead of sh (since we use a few bashisms). 2007-10-29 10:46:45 +00:00
Eelco Dolstra 42d80d1170 * On FreeBSD, sys/mount.h needs sys/param.h. 2007-10-29 10:03:07 +00:00
Eelco Dolstra d91cd30563 * Detect whether chroot / bind-mount support is available. 2007-10-27 16:51:55 +00:00
Eelco Dolstra 93aefd9fc0 * Give unpacked channels more sensible names than 0, 1, ... They now
get the basename of the channel URL (e.g., nixpkgs-unstable).  The
  top-level Nix expression of the channel is now an attribute set, the
  attributes of which are the individual channels (e.g.,
  {nixpkgs_unstable = ...; strategoxt_unstable = ...}).  This makes
  attribute paths ("nix-env -qaA" and "nix-env -iA") more sensible,
  e.g., "nix-env -iA nixpkgs_unstable.subversion".
2007-05-01 23:16:38 +00:00
Eelco Dolstra 2716f9bc5f * It seems that svnversion prints a carriage return on Cygwin, so we
get a invalid #define VERSION.  Use "svnversion -n" to leave out the
  newline.  Fix provided by Marc Weber.
2007-04-16 12:00:13 +00:00
Eelco Dolstra db1973d012 * Look for the openssl program at compile time. If not found, call
openssl through $PATH at runtime.
2007-03-01 13:30:46 +00:00
Eelco Dolstra d03f0d4117 * Check for lchown. 2006-12-07 18:51:11 +00:00
Eelco Dolstra 9f0efa6611 * Start of the setuid helper (the program that performs the operations
that have to be done as root: running builders under different uids,
  changing ownership of build results, and deleting paths in the store
  with the wrong ownership).
2006-12-06 01:24:02 +00:00
Eelco Dolstra 84d6459bd5 * Use setreuid if setresuid is not available. 2006-12-03 14:32:22 +00:00
Eelco Dolstra 40b3f64b55 * Skeleton of the privileged worker program.
* Some refactoring: put the NAR archive integer/string serialisation
  code in a separate file so it can be reused by the worker protocol
  implementation.
2006-11-30 19:19:59 +00:00
Eelco Dolstra 71e867c5f5 * Remove --enable-setuid, --with-nix-user and --with-nix-group.
Rather, setuid support is now always compiled in (at least on
  platforms that have the setresuid system call, e.g., Linux and
  FreeBSD), but it must enabled by chowning/chmodding the Nix
  binaries.
2006-11-29 21:06:58 +00:00
Eelco Dolstra e790404318 * Don't use the result of `uname -p' on x86_64 as it gives wacky
results on some machines. (NIX-69)
2006-11-13 14:54:18 +00:00
Eelco Dolstra 1d694eef4c * Require Perl 5.8.0 or newer. I mean, it *is* more than four years
old...
2006-10-19 19:20:18 +00:00
