Eelco Dolstra 969a14599d If "pv" is available at compile time, hard-code its path 2012-04-13 14:41:33 +02:00
Eelco Dolstra 4b23900ff1 Fix the optional dependency on OpenSSL

Eelco Dolstra b006a31d52 Drop the externals directory
Nix now requires SQLite and bzip2 to be pre-installed.  SQLite is
detected using pkg-config.  We required DBD::SQLite anyway, so
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 f86fca9b70 * Figure out the extension of dynamic libraries; don't hard-code .so. 2012-01-11 15:41:42 +00:00
Eelco Dolstra a7366a764a * Add a -I flag to the Perl bindings to nix-build and some other
scripts.
* Include the version and architecture in the -I flag so that there is
  at least a chance that a Nix binary built for one Perl version will
  run on another version.

Eelco Dolstra 9d43a02382 * Let --disable-gc work. 2012-01-04 12:45:40 +00:00
Eelco Dolstra 39d45a6b09 * Add a test for nix-channel.
* Refactor the nix-channel unpacker a bit.

Eelco Dolstra 4de3e2a0db * Doh. 2011-11-21 13:22:34 +00:00
Eelco Dolstra 23e933b3b3 * Put back the "sys_name" variable which got removed somewhere. This
broke building on Cygwin and Solaris.
2011-11-21 12:23:48 +00:00
Eelco Dolstra a6abade8e8 * Escape the [ and ] characters in the sed call, otherwise autoconf
will eat them.
2011-11-21 12:18:26 +00:00
Eelco Dolstra 964399c079 * "sed" on FreeBSD doesn't know the "+" operator. 2011-11-20 19:23:50 +00:00
Eelco Dolstra b92f76374f * In the platform, canonicalise "amd64" to "x86_64". FreeBSD 8.2's
uname reports amd64.
* Drop the FreeBSD version number, e.g. "i686-freebsd" instead of
  "i686-freebsd8.2".

Ludovic Courtès 42164d6de4 configure: Change i*86 to i686 as has always been done. 2011-11-16 20:58:21 +00:00
Ludovic Courtès 45ec69cbdf configure: Rely on `AC_CANONICAL_HOST' to determine the Nix system name.
This should be more robust and also plays better with
cross-compilation---it uses the host name, instead of using the build
name.
2011-11-16 20:39:59 +00:00
Eelco Dolstra c0b706213d * Boldly make SQLite WAL mode the default again. Hopefully the
intermittent problems are gone by now.  WAL mode is preferrable
  because it does way fewer fsyncs.
2011-11-07 21:11:59 +00:00
Eelco Dolstra 6fcdbcac20 * Install NixManifest.pm, NixConfig.pm and GeneratePatches.pm under
the Nix:: namespace.
2011-10-10 21:11:08 +00:00
Eelco Dolstra 73fe6871c4 * Include the Nix Perl bindings in Nix itself. This will allow the
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.
2011-10-10 18:12:40 +00:00
Eelco Dolstra d9a5959139 * Show the default for --with-store-dir (Nix/211). 2011-07-13 15:57:44 +00:00

Eelco Dolstra 4891b21f34 * Use SQLite 3.7.6.2. 2011-05-03 16:17:24 +00:00
Eelco Dolstra 3cbf680f5d * configure: detect whether DBD::SQLite is present. If necessary the
location to DBI and DBD::SQLite can be passed with --with-dbi and
  --with-dbd-sqlite.
2011-04-11 10:13:53 +00:00
Eelco Dolstra 538b7caab0 * Don't allocate a big initial GC address space on machines with
little RAM.  Even if the memory isn't actually used, it can cause
  problems with the overcommit heuristics in the kernel.  So use a VM
  space of 25% of RAM, up to 384 MB.
2011-02-10 14:31:04 +00:00
Ludovic Courtès f1462c208b Use $BDW_GC_LIBS instead of a custom variable. 2011-02-09 21:23:13 +00:00
Eelco Dolstra 1876ab764f * A better fix. $boehmgc isn't set anywhere, we should use the flags
returned by pkg-config.

Eelco Dolstra 4d57776813 * Use SQLite 3.7.4. 2010-12-10 11:45:56 +00:00
Eelco Dolstra fb9368b5a0 * Sync with the trunk. 2010-11-16 12:49:47 +00:00
Eelco Dolstra 3d71c8013e * Use pkgconfig to locate the Boehm GC (as suggested by Ludo), if
--enable-gc is given.
2010-10-29 14:00:47 +00:00
Eelco Dolstra 64c3325b0b * Make building against the Boehm GC a configure option. 2010-10-22 13:39:15 +00:00
Eelco Dolstra 95f4f2cf61 * If std::tr1::unordered_set is unavailable, use std::set. 2010-10-04 16:16:19 +00:00
Eelco Dolstra e41ecbf730 2010-08-27 11:09:04 +00:00
Eelco Dolstra 5fb824e896 * Urgh, this was supposed to go in the trunk... 2010-08-12 13:36:56 +00:00
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.

Peter Simons a0d29040f7 Revert "configure.ac: make flex and bison required programs"
This reverts commit 22405. Apparently, these programs aren't necessarily
required when building from a release archive.

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 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

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 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
Eelco Dolstra 7bada48b36 * Bumped the version number to 0.11. 2006-10-06 13:45:29 +00:00
Eelco Dolstra 4cab35d1a6 * Build with -D_FILE_OFFSET_BITS=64 to support files >= 2^31 bytes
(NIX-22).
2006-09-22 11:13:12 +00:00
Eelco Dolstra 22d13d6ec2 * Check for patch (NIX-59). 2006-09-20 15:28:47 +00:00
Eelco Dolstra aab8812732 * Store the Nix libraries in ${libdir}/nix instead of ${libdir}. 2006-09-04 15:12:24 +00:00
Eelco Dolstra e5678b3435 * Map "ppc" to "powerpc" so that Linux on PowerPC will be reported as
"powerpc-linux".
2006-08-25 16:23:42 +00:00
Eelco Dolstra 1a9a1f2768 * Convert to DocBook 5.
* Use Jing for RelaxNG validation, xmllint seems buggy.
2006-08-21 16:05:11 +00:00
Eelco Dolstra 2d456fc35a * On Cygwin, set the system type to i686-cygwin, and disable dynamic
linking.
2006-05-31 11:50:14 +00:00
Eelco Dolstra 03162f8f47 * Unless --with-bzip2 is specified, use a copy of bzip2 in the
externals directory.  This is in particular useful because though
  most systems have bzip2/bunzip2, they don't always have libbz2,
  which we need for bsdiff/bspatch.
2006-04-25 10:45:53 +00:00
Eelco Dolstra a4c63c6e8e * Make it easy to run individual tests from the command line. 2006-03-01 12:15:33 +00:00
Eelco Dolstra ddb78dfc3d * Check whether "nix-store -q --graph" generates a valid dot graph.
* Test "nix-store -q --tree" as well.
2006-02-22 13:55:41 +00:00
Eelco Dolstra d6f586d0ea * Optional switch "--with-openssl=<PATH>" to use OpenSSL's
implementations of MD5, SHA-1 and SHA-256.  The main benefit is that
  we get assembler-optimised implementations of MD5 and SHA-1 (though
  not SHA-256 (at least on x86), unfortunately).  OpenSSL's SHA-1

Eelco Dolstra 4f07ebc67e * Integrated bsdiff/bspatch 4.2 (from
http://www.daemonology.net/bsdiff/bsdiff-4.2.tar.gz) into the source
  tree.  The license is a bit peculiar, but it does allow verbatim
  copying, which is what we do here (i.e., so don't make any changes
  to the sources).
2004-12-29 22:08:48 +00:00
Eelco Dolstra 3d1b2101cc * Place manifests in /nix/var/nix/manifests.

Eelco Dolstra ed09821859 * Use atdiff' instead of cmp' for checking test output.
* Don't use local file names in tests since they will produce
  different parse trees depending on the current directory.
2004-10-27 13:12:58 +00:00
Eelco Dolstra 3ade3e7721 * Revert r1594 - it didn't solve the problem. Instead add
svn-revision to distributions, which should fix it.
2004-10-25 13:51:34 +00:00
Eelco Dolstra 2248becfd3 * Make sure that the prerelease version is included in `--version'. 2004-10-25 12:15:50 +00:00
Eelco Dolstra 47f87072ad * A very dirty hack to make setuid installations a bit nicer to use.
Previously there was the problem that all files read by nix-env
  etc. should be reachable and readable by the Nix user.  So for
  instance building a Nix expression in your home directory meant that
  the home directory should have at least g+x or o+x permission so
  that the Nix user could reach the Nix expression.  Now we just
  switch back to the original user just prior to reading sources and
  the like.  The places where this happens are somewhat arbitrary,
  however.  Any scope that has a live SwitchToOriginalUser object in
  it is executed as the original user.

* Back out r1385.  setreuid() sets the saved uid to the new
  real/effective uid, which prevents us from switching back to the
  original uid.  setresuid() doesn't have this problem (although the
  manpage has a bug: specifying -1 for the saved uid doesn't leave it
  unchanged; an explicit value must be specified).
2004-09-09 21:12:53 +00:00
Eelco Dolstra 5396304c73 * Use setre[ug]id() instead of setres[ug]id(), since the former is
more common than the latter (which exists only on Linux and
  FreeBSD).  We don't really care about dropping the saved IDs since
  there apparently is no way to quiry them in any case, so it can't
  influence the build (unlike the effective IDs which are checked by
  Perl for instance).
2004-09-09 15:55:31 +00:00
Eelco Dolstra e77fbe0fa2 * On systems that have the setresuid() and setresgid() system calls to
set the real uid and gid to the effective uid and gid, the Nix
  binaries can be installed as owned by the Nix user and group instead
  of root, so no root involvement of any kind is necessary.

  Linux and FreeBSD have these functions.
2004-08-20 15:22:33 +00:00
Eelco Dolstra 2d35116c13 * Setuid support for sharing a Nix installation between multiple
users.

  If the configure flag `--enable-setuid' is used, the Nix programs
  nix-env, nix-store, etc. are installed with the setuid bit turned on
  so that they are executed as the user and group specified by
  `--with-nix-user=USER' and `--with-nix-group=GROUP', respectively
  (with defaults `nix' and `nix').

  The setuid programs drop all special privileges if they are executed
  by a user who is not a member of the Nix group.

  The setuid feature is a quick hack to enable sharing of a Nix
  installation between users who trust each other.  It is not
  generally secure, since any user in the Nix group can modify (by
  building an appropriate derivation) any object in the store, and for
  instance inject trojans into binaries used by other users.

  The setuid programs are owned by root, not the Nix user.  This is
  because on Unix normal users cannot change the real uid, only the
  effective uid.  Many programs don't work properly when the real uid
  differs from the effective uid.  For instance, Perl will turn on
  taint mode.  However, the setuid programs drop all root privileges
  immediately, changing all uids and gids to the Nix user and group.
2004-08-20 14:49:05 +00:00
Eelco Dolstra 966bd9d19f * WTF? More canonical system name problems ("athlon-linux" instead of
"i686-linux").
2004-08-13 09:57:51 +00:00
Eelco Dolstra 39eaecbc98 * Slightly better heuristic for picking the canonical system type.
Now SuSE and Red Hat should yield the same type (`i686-linux').  Mac
  OS X should now give `powerpc-darwin' (i.e., the version number is
  gone).
2004-07-18 21:07:27 +00:00
Eelco Dolstra 37ee6cef99 * Adapted nix-pull to use the new substitute mechanism. 2004-06-21 09:51:23 +00:00
Eelco Dolstra e8411948ff * A Nix mode for Emacs. 2004-06-04 14:31:57 +00:00
Eelco Dolstra 19479899fb * Don't set the rpath here --- it's not portable. 2004-05-18 12:57:26 +00:00
Eelco Dolstra 1d08093b48 * Go back to the old way of generating the system name, and allow it
to be specified in configure (using `--with-system=SYSTEM').
2004-05-18 09:45:46 +00:00
Eelco Dolstra 256eeab711 * Allow the location of the store etc. to be specified using
environment variables.
* Started adding some automatic tests.
* Do a `make check' when building RPMs.
2004-05-04 12:15:30 +00:00
Eelco Dolstra fd927c5d25 * Bump the version number. 2004-04-26 13:44:26 +00:00
Eelco Dolstra bcce9c1ff5 * Only add `-preRELEASE' to the version if STABLE != 1.
* Documented release procedures.
2004-04-26 09:52:06 +00:00
Eelco Dolstra d4779abc04 * Pass SYSTEM through config.h, and allow spaces. 2004-04-23 15:16:08 +00:00
Eelco Dolstra 21655a70f5 * Channels. These allow you to stay current with an evolving set of
Nix expressions.

  To subscribe to a channel (needs to be done only once):

    nix-channel --add \
      http://catamaran.labs.cs.uu.nl/dist/nix/channels/nixpkgs-unstable

  This just adds the given URL to ~/.nix-channels (which can also be
  edited manually).

  To update from all channels:

    nix-channel --update

  This fetches the latest expressions and pulls cache manifests.  The
  default Nix expression (~/.nix-defexpr) is made to point to the
  conjunction of the expressions downloaded from all channels.

  So to update all installed derivations in the current user
  environment:

    nix-channel --update
    nix-env --upgrade '*'

  If you are really courageous, you can put this in a cronjob or
  something.

  You can subscribe to multiple channels.  It is not entirely clear
  what happens when there are name clashes between derivations from
  different channels.  From nix-env/main.cc it appears that the one
  with the lowest (highest?) hash will be used, which is pretty
  meaningless.

Eelco Dolstra f79e9c2d22 * Do initialise state (the DB etc.) when doing a `make install',
unless `--disable-init-state' is passed to configure.
2004-04-21 10:54:46 +00:00
Eelco Dolstra b0c9baf1b5 * EBNF grammar for the Nix expression language. 2004-04-08 13:31:57 +00:00
Eelco Dolstra bf3863b546 * Fail if prerequisites are missing. 2004-04-06 08:40:19 +00:00
Eelco Dolstra 03f1d1ecb5 * Switched from wget to curl.
* Made the dependencies on bzip2 and the shell explicit.
2004-04-06 08:18:51 +00:00
Eelco Dolstra 9d2669d218 * Added a utility that can be used to produce nice HTML pages from Nix
build logs.  The program `log2xml' converts a Nix build log (read
  from standard input) into XML file that can then be converted to
  XHTML by the `log2html.xsl' stylesheet.  The CSS stylesheet
  `logfile.css' is necessary to make it look good.

  This is primarily useful if the log file has a *tree structure*,
  i.e., that sub-tasks such as the various phases of a build (unpack,
  configure, make, etc.) or recursive invocations of Make are
  represented as such.  While a log file is in principle an
  unstructured plain text file, builders can communicate this tree
  structure to `log2xml' by using escape sequences:

  - "\e[p" starts a new nesting level; the first line following the
    escape code is the header;

  - "\e[q" ends the current nesting level.

  The generic builder in nixpkgs (not yet committed) uses this.  It
  shouldn't be to hard to patch GNU Make to speak this protocol.

  Further improvements to the generated HTML pages are to allow
  collapsing/expanding of subtrees, and to abbreviate store paths (but
  to show the full path by hovering the mouse over it).
2004-03-15 21:51:14 +00:00
Eelco Dolstra beda10f5a2 * Make perl a dependency of Nix. 2004-03-15 15:23:53 +00:00
Eelco Dolstra 0dfdafdf6d * Allow linking against an external Berkeley DB / ATerm library. 2004-02-16 16:37:16 +00:00
Eelco Dolstra f34de12140 * Allow the location of the store to be specified (--with-store-dir).
* Do not create stuff in localstatedir when doing `make install'
  (since we may not have write access).  In general, installation of
  constant code/data should be separate from the initialisation of
  mutable state.
