4f4a14453a Don't set $PS1 in non-interactive shells

4ea034a5c5 nix-shell: Play nicely with non-interactive shells
nix-shell with the --command flag might be used non-interactively, but
if bash starts non-interactively (i.e. with stdin or stderr not a
terminal), it won't source the script given in --rcfile. However, in
that case it *will* source the script found in $BASH_ENV, so we can use
that instead.

Also, don't source ~/.bashrc in a non-interactive shell (detectable by
checking the PS1 env var)

c1994fecf9 nix-shell: Fix bash completion
Nixpkgs's stdenv setup script sets the "nullglob" option, but doing so
breaks Bash completion on NixOS (when ‘programs.bash.enableCompletion’
is set) and on Ubuntu.  So clear that flag afterwards.  Of course,
this may break stdenv functions in subtle ways...

511455965e nix-shell: Don't disable Automake dependency tracking
Nixpkgs' stdenv disables dependency tracking by default.  That makes
sense for one-time builds, but in an interactive environment we expect
repeated "make" invocations to do the right thing.

a4921b8ceb Revert "build-remote.pl: Enforce timeouts locally"
This reverts commit 69b8f9980f.

The timeout should be enforced remotely.  Otherwise, if the garbage
collector is running either locally or remotely, if will block the
build or closure copying for some time.  If the garbage collector
takes too long, the build may time out, which is not what we want.
Also, on heavily loaded systems, copying large paths to and from the
remote machine can take a long time, also potentially resulting in a
timeout.

78206f06ec build-remote.pl: Allow a machine to refuse a build
Before selecting a machine, build-remote.pl will try to run the
command "nix-builds-inhibited" on the machine.  If this command exists
and returns a 0 exit code, then the machine won't be used.  It's up to
the user to provide this command, but it would typically be a script
that checks whether there is enough disk space and whether the load is
not too high.

Don't pass --timeout / --max-silent-time to the remote builder.
Instead, let the local Nix process terminate the build if it exceeds a

gives better error reporting (since the timeout message from the
remote side wasn't properly propagated) and handles non-Nix problems
like SSH hangs.

9958bd6992 Add operation ‘nix-store --repair-path’
This operation allows fixing corrupted or accidentally deleted store
paths by redownloading them using substituters, if available.

Since the corrupted path cannot be replaced atomically, there is a
very small time window (one system call) during which neither the old
(corrupted) nor the new (repaired) contents are available.  So
repairing should be used with some care on critical packages like
Glibc.

66a3ac6a56 Allow a binary cache to declare that it doesn't support "nix-env -qas"
Querying all substitutable paths via "nix-env -qas" is potentially
hard on a server, since it involves sending thousands of HEAD
requests.  So a binary cache must now have a meta-info file named
"nix-cache-info" that specifies whether the server wants this.  It
also specifies the store prefix so that we don't send useless queries
to a binary cache for a different store prefix.

b74d92755d download-from-binary-cache: Use HEAD requests if possible
In "nix-env -qas", we don't need the substitute info, we just need to
know if it exists.  This can be done using a HTTP HEAD request, which
saves bandwidth.

Note however that curl currently has a bug that prevents it from
reusing HTTP connections if HEAD requests return a 404:

https://sourceforge.net/tracker/?func=detail&aid=3542731&group_id=976&atid=100976

Without the patch attached to the issue, using HEAD is actually quite
a bit slower than GET.

11800e6198 download-from-binary-cache: parallelise fetching of NAR info files
Getting substitute information using the binary cache substituter has
non-trivial latency overhead.  A package or NixOS system configuration
can have hundreds of dependencies, and in the worst case (when the
local info cache is empty) we have to do a separate HTTP request for
each of these.  If the ping time to the server is t, getting N info
files will take tN seconds; e.g., with a ping time of 0.1s to
nixos.org, sequentially downloading 1000 info files (a typical NixOS
config) will take at least 100 seconds.

To fix this problem, the binary cache substituter can now perform
requests in parallel.  This required changing the substituter
interface to support a function querySubstitutablePathInfos() that
queries multiple paths at the same time, and rewriting queryMissing()
to take advantage of parallelism.  (Due to local caching,
parallelising queryMissing() is sufficient for most use cases, since
it's almost always called before building a derivation and thus fills
the local info cache.)

For example, parallelism speeds up querying all 1056 paths in a
particular NixOS system configuration from 116s to 2.6s.  It works so
well because the eccentricity of the top-level derivation in the
dependency graph is only 9.  So we only need 10 round-trips (when
using an unlimited number of parallel connections) to get everything.

Currently we do a maximum of 150 parallel connections to the server.
Thus it's important that the binary cache server (e.g. nixos.org) has
a high connection limit.  Alternatively we could use HTTP pipelining,
but WWW::Curl doesn't support it and libcurl has a hard-coded limit of
5 requests per pipeline.

cd94665f38 download-from-binary-cache: use WWW::Curl
Using WWW::Curl rather than running an external curl process for every
NAR info file halves the time it takes to get info thanks to libcurl's
support for persistent HTTP connections.  (We save a roundtrip per
file.)  But the real gain will come from using parallel and/or
pipelined requests.

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.

49cd7387ad nix-push: create a manifest-less binary cache
Manifests are a huge pain, since users need to run nix-pull directly
or indirectly to obtain them.  They tend to be large and lag behind
the available binaries; also, the downloaded manifests in
/nix/var/nix/manifest need to be in sync with the Nixpkgs sources.  So
we want to get rid of them.

The idea of manifest-free operation works as follows.  Nix is
configured with a set of URIs of binary caches, e.g.

  http://nixos.org/binary-cache

Whenever Nix needs a store path X, it checks each binary cache for the
existence of a file <CACHE-URI>/<SHA-256 hash of X>.narinfo, e.g.

  http://nixos.org/binary-cache/bi1gh9...ia17.narinfo

The .narinfo file contains the necessary information about the store
path that was formerly kept in the manifest, i.e., (relative) URI of
the compressed NAR, references, size, hash, etc.  For example:

  StorePath: /nix/store/xqp4l88cr9bxv01jinkz861mnc9p7qfi-neon-0.29.6
  URL: 1bjxbg52l32wj8ww47sw9f4qz0r8n5vs71l93lcbgk2506v3cpfd.nar.bz2
  CompressedHash: sha256:1bjxbg52l32wj8ww47sw9f4qz0r8n5vs71l93lcbgk2506v3cpfd
  CompressedSize: 202542
  NarHash: sha256:1af26536781e6134ab84201b33408759fc59b36cc5530f57c0663f67b588e15f
  NarSize: 700440
  References: 043zrsanirjh8nbc5vqpjn93hhrf107f-bash-4.2-p24 cj7a81wsm1ijwwpkks3725661h3263p5-glibc-2.13 ...
  Deriver: 4idz1bgi58h3pazxr3akrw4fsr6zrf3r-neon-0.29.6.drv
  System: x86_64-linux

Nix then knows that it needs to download

  http://nixos.org/binary-cache/1bjxbg52l32wj8ww47sw9f4qz0r8n5vs71l93lcbgk2506v3cpfd.nar.bz2

to substitute the store path.

Note that the store directory is omitted from the References and
Deriver fields to save space, and that the URL can be relative to the
binary cache prefix.

This patch just makes nix-push create binary caches in this format.
The next step is to make a substituter that supports them.

6814b1dfa1 Generate binary tarballs for installing Nix
For several platforms we don't currently have "native" Nix packages
(e.g. Mac OS X and FreeBSD).  This provides the next best thing: a
tarball containing the closure of Nix, plus a simple script
"nix-finish-install" that initialises the Nix database, registers the
paths in the closure as valid, and runs "nix-env -i /path/to/nix" to
initialise the user profile.

The tarball must be unpacked in the root directory.  It creates
/nix/store/... and /usr/bin/nix-finish-install.  Typical installation
is as follows:

  $ cd /
  $ tar xvf /path/to/nix-1.1pre1234_abcdef-x86_64-linux.tar.bz2
  $ nix-finish-install
  (if necessary add ~/.nix-profile/etc/profile.d/nix.sh to the shell
  login scripts)

After this, /usr/bin/nix-finish-install can be deleted, if desired.

The downside to the binary tarball is that it's pretty big (~55 MiB
for x86_64-linux).

e855c7e2c9 nix-channel improvements
"nix-channel --add" now accepts a second argument: the channel name.
This allows channels to have a nicer name than (say) nixpkgs_unstable.
If no name is given, it defaults to the last component of the URL
(with "-unstable" or "-stable" removed).

Also, channels are now stored in a profile
(/nix/var/nix/profiles/per-user/$USER/channels).  One advantage of
this is that it allows rollbacks (e.g. if "nix-channel --update" gives
an undesirable update).

we can do:

  $ nix-build --run-env release.nix -A build --exclude 'hydra-tarball'

This will skip the dependency whose name matches the "hydra-tarball"
regular expression.  The "--exclude" option can be repeated any number

7f38087f35 Add a command "nix-build --run-env" to reproduce the environment of a derivation
This command builds or fetches all dependencies of the given

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

Eelco Dolstra
a95ba4cdd9 * Use last_insert_id instead of sqlite_last_insert_rowid, which you're
not really supposed to use according to the DBD::SQLite docs, and
  fails on some systems (e.g. http://hydra.nixos.org/build/1246662).
2011-08-17 14:17:19 +00:00
Eelco Dolstra
1ecc97b6bd * Add a Nix expression search path feature. Paths between angle
brackets, e.g.

    import <nixpkgs/pkgs/lib>

  are resolved by looking them up relative to the elements listed in
  the search path.  This allows us to get rid of hacks like

    import "${builtins.getEnv "NIXPKGS_ALL"}/pkgs/lib"

  The search path can be specified through the ‘-I’ command-line flag
  and through the colon-separated ‘NIX_PATH’ environment variable,
  e.g.,

    $ nix-build -I /etc/nixos ...

  If a file is not found in the search path, an error message is
  lazily thrown.

Eelco Dolstra
e649f3168b * Fix concurrency issues in download-using-manifests' handling of the
SQLite manifest cache.  The DBI AutoCommit feature caused every
  process to have an active transaction at all times, which could
  indefinitely block processes wanting to update the manifest cache.

* Disable fsync() in the manifest cache because we don't need
  integrity (the cache can always be recreated if it gets corrupted).
2011-07-13 14:05:54 +00:00
Eelco Dolstra
d94cb02bfe * nix-install-package: unset NIX_REMOTE because $NIX_MANIFESTS_DIR
doesn't work when building through the Nix daemon.  This also
  ensures an error message when the user doesn't have sufficient
  privileges to do nix-pull.
2011-04-19 10:52:35 +00:00
Eelco Dolstra
412914d004 * Read manifests directly into the database, rather than first reading
them into memory.  This brings memory use down to (more or less)
  O(1).  For instance, on my test case, the maximum resident size of
  download-using-manifests while filling the DB went from 142 MiB to
  11 MiB.

Eelco Dolstra
5591fcc529 * Cache the manifests in /nix/var/nix/manifests in a SQLite database.
This significantly speeds up the download-using-manifests
  substituter, especially if manifests are very large.  For instance,
  one "nix-build -A geeqie" operation that updated four packages using
  binary patches went from 18.5s to 1.6s.  It also significantly
  reduces memory use.

  The cache is kept in /nix/var/nix/manifests/cache.sqlite.  It's
  updated automatically when manifests are added to or removed from
  /nix/var/nix/manifests.  It might be interesting to have nix-pull
  store manifests directly in the DB, rather than storing them as
  separate flat files, but then we would need a command line interface
  to delete manifests from the DB.

Eelco Dolstra
a4f0365b2d * When checking whether a patch is applicable, for efficiency, use
`nix-store -q --hash' to get the hash of the base path rather than
  `nix-hash'.  However, only do this for estimating the size of a
  download, not for the actual substitution, because sometimes the
  contents of store paths are modified (which they shouldn't, of
  course).

Eelco Dolstra
80e722278c * When using the build hook, distinguish between the stderr of the
hook script proper, and the stdout/stderr of the builder.  Only the
  latter should be saved in /nix/var/log/nix/drvs.
* Allow the verbosity to be set through an option.
* Added a flag --quiet to lower the verbosity level.
2010-08-30 14:53:03 +00:00
Eelco Dolstra
766f708418 * Experimental feature: allow a derivation to tell the build hook that
it requires a certain feature on the build machine, e.g.

    requiredSystemFeatures = [ "kvm" ];

  We need this in Hydra to make sure that builds that require KVM
  support are forwarded to machines that have KVM support.  Probably
  this should also be enforced for local builds.
2010-08-27 13:18:13 +00:00
Eelco Dolstra
e437b08250 * Made the build hook mechanism more efficient. Rather than starting
the hook every time we want to ask whether we can run a remote build
  (which can be very often), we now reuse a hook process for answering
  those queries until it accepts a build.  So if there are N
  derivations to be built, at most N hooks will be started.

Eelco Dolstra
2897286487 * Unify exportReferencesGraph and exportBuildReferencesGraph, and make
sure that it works as expected when you pass it a derivation.  That
  is, we have to make sure that all build-time dependencies are built,

  might fail, for example).  This is ensured at instantiation time by
  adding all derivations and their sources to inputDrvs and inputSrcs.

041717eda3 * download-using-manifests: don't check the cryptographic hash of
downloaded files; rather, check the hash of the unpacked store
  path.

  When the server produces bzipped NAR archives on demand (like Hydra
  does), the hash of the file is not known in advance; it's streamed
  from the server.  Thus the manifest doesn't contain a hash for the
  bzipped NAR archive.  However, the server does know the hash of the
  *uncompressed* NAR archive (the "NarHash" field), since it's stored
  in the Nix database (nix-store -q --hash /nix/store/bla).  So we use
  that instead for checking the integrity of the download.

makes more sense for the build farm, otherwise every nix-store
  invocation will lead to at least one local build.  Will come up with
  a better solution later...
2008-12-04 16:35:47 +00:00
Eelco Dolstra
909fbb9de1 * When using build hooks, for any nix-store -r build operation, it is
necessary that at least one build hook doesn't return "postpone",
  otherwise nix-store will barf ("waiting for a build slot, yet there
  are no running children").  So inform the build hook when this is
  the case, so that it can start a build even when that would exceed
  the maximum load on a machine.

9fd9c4c635 * Support multiple system types per remote machine, e.g. a machine
list like

    root@example.org x86_64-linux /root/.ssh/id_buildfarm 1
    root@example.org i686-darwin  /root/.ssh/id_buildfarm 1

  This is possible when the Nix installation on example.org itself has
  remote builds enabled.

f8713e1287 * Dirty hack to make nix-push work properly on derivations: the
derivation should be a source rather than a derivation dependency of
  the call to the NAR derivation.  Otherwise the derivation (and all
  its dependencies) will be built as a side-effect, which may not even
  succeed.

aab530e971 * Primop builtins.storePath for declaring a store path as a
dependency.  `storePath /nix/store/bla' gives exactly the same
  result as `toPath /nix/store/bla', except that the former includes
  /nix/store/bla in the dependency context of the string.

  Useful in some generated Nix expressions like nix-push, which now
  finally does the right thing wrt distributed builds.  (Previously
  the path to be packed wasn't an explicit dependency, so it wouldn't
  be copied to the remote machine.)

b455c4c45c Updates to nix-reduce-build
Common code in local build package sources refactored out in a function; before building the real set of derivations needed is found (slightly slower for only one build strategy, but less garbage on output and better performance for multiple build strategies).

Now you have full choice of best-effort build regardless of method (substituters or actual build), using substituters, building only fixed derivations (should get you all the downloads) and local build without even trying substituters. 

Some minor fix in the help text about behavior with no package sources.

3c92ea399d * Make nix-env --dry-run print the paths to be substituted correctly
again.  (After the previous substituter mechanism refactoring I
  didn't update the code that obtains the references of substitutable

  are now kept running and receive/respond to info requests via
  stdin/stdout.

Eelco Dolstra
8bc591a6f0 * Use the copy-from-other-stores substituter by default. Of course,
it only does something if $NIX_OTHER_STORES (not really a good
  name...) is set.
* Do globbing on the elements of $NIX_OTHER_STORES.  E.g. you could
  set it to /mnts/*/nix or something.
* Install substituters in libexec/nix/substituters.
2008-07-18 13:05:10 +00:00
Eelco Dolstra
15f39aba8c * Quick prototype of a substituter that copies paths from other Nix
stores (typically remote Nix stores mounted via e.g. NFS, or the Nix
  store on the NixOS installation CD).  Example use:

  $ sshfs foo@example.org:/ /mnt
  $ NIX_OTHER_STORES=/mnt/nix \
    NIX_SUBSTITUTERS=.../copy-from-other-stores.pl \
    nix-env -i foo

  This will be especially useful for the installation CD since it
  doesn't require a manifest for the CD contents.

a8629de827 * New command `nix-store --optimise' to reduce Nix store disk space
usage by finding identical files in the store and hard-linking them
  to each other.  It typically reduces the size of the store by
  something like 25-35%.  This is what the optimise-store.pl script
  did, but the new command is faster and more correct (it's safe wrt
  garbage collection and concurrent builds).

26f981c2e5 * Remove garbage. 2007-09-18 08:26:55 +00:00
Eelco Dolstra
055608227f * nix-env: allow ~/.nix-defexpr to be a directory. If it is, then the
Nix expressions in that directory are combined into an attribute set
  {file1 = import file1; file2 = import file2; ...}, i.e. each Nix
  expression is an attribute with the file name as the attribute
  name.  Also recurses into directories.

* nix-env: removed the "--import" (-I) option which set the
  ~/.nix-defexpr symlink.

* nix-channel: don't use "nix-env --import", instead symlink
  ~/.nix-defexpr/channels.  So finally nix-channel --update doesn't
  override any default Nix expressions but combines with them.

  This means that you can have (say) a local Nixpkgs SVN tree and use
  it as a default for nix-env:

  $ ln -s .../path-to-nixpkgs-tree ~/.nix-defexpr/nixpkgs_svn

  and be subscribed to channels (including Nixpkgs) at the same time.
  (If there is any ambiguity, the -A flag can be used to
  disambiguate, e.g. "nix-env -i -A nixpkgs_svn.pan".)

7d5836b34d * nix-channel: supports users who don't have write permission to the
manifests directory.  In that case, we don't do a nix-pull, so the
  user gets pure source deployment.

  The directory /nix/var/nix/gcroots/per-user/$USER should be
  writable.  (It's created automatically if
  /nix/var/nix/gcroots/per-user is writable, e.g. if it has 1777
  permission.)

Eelco Dolstra
9e975458b4 * Get rid of the substitutes database table (NIX-47). Instead, if we
need any info on substitutable paths, we just call the substituters
  (such as download-using-manifests.pl) directly.  This means that
  it's no longer necessary for nix-pull to register substitutes or for
  nix-channel to clear them, which makes those operations much faster
  (NIX-95).  Also, we don't have to worry about keeping nix-pull
  manifests (in /nix/var/nix/manifests) and the database in sync with
  each other.

  The downside is that there is some overhead in calling an external
  program to get the substitutes info.  For instance, "nix-env -qas"
  takes a bit longer.

  Abolishing the substitutes table also makes the logic in
  local-store.cc simpler, as we don't need to store info for invalid
  paths.  On the downside, you cannot do things like "nix-store -qR"
  on a substitutable but invalid path (but nobody did that anyway).

* Never catch interrupts (the Interrupted exception).

and store the manifests in the Nix store.  (So now

  searched for GC roots.)
2007-08-09 23:52:53 +00:00
Eelco Dolstra
f881f7a017 * nix-prefetch-url: support caching. If the environment variable
NIX_DOWNLOAD_CACHE is set, then nix-prefetch-url will store the hash
  and timestamp of downloaded files in the directory
  $NIX_DOWNLOAD_CACHE.  This allows it to figure out if the file is
  still in the Nix store.

Eelco Dolstra
9bff7ad728 * Check against creation of GC roots in the store. Those roots don't

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".

  infinity (0).

* Fix a tricky race condition: if we kill the build user before the

  killed, and we'll potentially lock up in pid.wait().  So also send a
  conventional kill to the child.

6dbed1bf38 * `optimise-store.pl' reduces disk space consumption by hard-linking
all identitical files in the Nix store to each other.  (Previously
  it only computed the size that would be saved by doing so.)

9488ae7357 * `show-duplication.pl', a small utility that shows the amount of
package duplication present in (e.g.) a profile.  It shows the
  number of instances of each package in a closure, along with the
  size in bytes of each instance as well as the "waste" (the
  difference between the sum of the sizes of all instances and the
  average size).

  $ ./show-duplication.pl /nix/var/nix/profiles/default
  gcc 11
    3.3.6 19293318
    3.4.4 21425257
    ...
    average 14942970, waste 149429707
  coreutils 6
  ...
  average package duplication 1.87628865979381, total size 3486330471, total waste 1335324237, 38.3017114443825% wasted

  This utility is useful for measuring the cost in terms of disk space
  of the Nix approach.

2e210b2387 * Convenience option `nix-collect-garbage -d' (--delete-old): removes
old generations of *all* profiles in /nix/var/nix/profiles, then
  runs the garbage collector.  Quick way to get rid of all old stuff.
  Of course, one cannot roll back to earlier points in time after
  this.

ebcccbd358 * Added a tool to find additional roots for the garbage collector,
such as open files, current directories, mmaped files, etc.  This is
  inherently unportable, but it's easy to adapt this script to other
  platforms.  Currently we call `lsof' and try to read various bits in
  /proc/NNN.

  The goal is to prevent the garbage collector from removing store
  paths that are no longer reachable from a permanent root but that
  are still in use (for instance, after the user has done "nix-env -e"
  on a running program).
