Eelco Dolstra 3d38a49840 * In the download size indication, take binary patches into account.
Hopefully this doesn't slow things down too much.
2010-11-17 17:32:25 +00:00
Eelco Dolstra bdf089f463 * Before a build, show the disk space that the downloaded store paths
will approximately require.
2010-11-17 14:31:42 +00:00
Eelco Dolstra 06699d4219 * Store the NAR size in the manifest. 2010-11-17 12:57:52 +00:00
Eelco Dolstra 5693b8a7e2 * nix-push: no need to compute the NAR hash, since the Nix database
already has it (`nix-store -q --hash').
2010-11-17 12:51:54 +00:00
Eelco Dolstra bfa6ee7d91 * Don't use SSH's `-tt' flag because it doesn't seem to work
on OpenSolaris when using connection sharing.  Instead have
  the remote side check for disconnection and kill the process 
  group when that happens.
2010-10-04 12:30:46 +00:00
Eelco Dolstra bf0dde9597 * Always print hook output on stderr, even if --no-build-output is
set.
* In the build hook, print a trace message to allow Hydra to pick up
  the name of the remote machine used for the build.
2010-08-31 12:36:24 +00:00
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.
2010-08-25 20:44:28 +00:00
Eelco Dolstra 1a396f3789 * Don't call "cat". 2010-08-25 12:19:30 +00:00
Eelco Dolstra 95deba581d * In the build hook, temporarily register the derivation and its
output as GC roots.  This prevents a race if the garbage collector
  is running during the build.
2010-08-25 11:54:11 +00:00
Eelco Dolstra 1e5f5ea2e9 * Correctly handle SSH failing to establish a connection. Because
this didn't work right, the build hook wouldn't fall back to using
  other machines of the desired type.
2010-08-24 14:27:07 +00:00
Eelco Dolstra 5f9aad44ca * nix-build: recognise --cores. 2010-08-11 15:28:02 +00:00
Eelco Dolstra 587dc8aa00 * Sync with the trunk. 2010-08-04 17:48:29 +00:00
Eelco Dolstra 532d766c27 * Don't barf if the source NAR for a patch has disappeared. 2010-07-21 11:30:23 +00:00
Eelco Dolstra 560ab22f7d * Ignore packages that don't have a version.
* Work on a manifest instead of a channel directory.
2010-06-23 21:11:33 +00:00
Eelco Dolstra 87ef5907e9 * Sync. 2010-06-22 14:42:34 +00:00
Eelco Dolstra 819548d92f * Pass `--fallback' to the remote build to ignore failing
substituters.
2010-06-22 14:41:22 +00:00
Eelco Dolstra c778ed1768 * Fix the copy-from-other-stores substituter. 2010-04-26 13:39:55 +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 68e55cd9da * Since Hydra now escapes +', =' and `?' to %NN in URIs,
nix-prefetch-url should unescape them, because `%' is not a valid
  character in store path names.
2010-02-16 00:10:39 +00:00
Eelco Dolstra 719cebcac2 * "Fix" incorrect help message. 2010-02-04 09:38:09 +00:00
Eelco Dolstra 443673620d * Don't use ssh's -f flag since it leads to lots of lingering ssh
processes.
2010-02-04 02:38:40 +00:00
Eelco Dolstra 7ec5a65925 * Doh! The scope of $slotLock should extend to the end of the script,
because otherwise the lock will be released at the end of the while
  loop.
2010-02-04 02:18:29 +00:00
Eelco Dolstra c9b2d80bcd * Typo. 2010-02-04 02:05:34 +00:00
Eelco Dolstra 3cfe65e516 * Doh! Calling `system' in an END block causes the exit status in $?
to be changed to 0.
2010-02-04 02:05:22 +00:00
Eelco Dolstra e51a276907 * Remove the `cat' calls when not using --gzip. 2010-02-04 01:39:23 +00:00
Eelco Dolstra 408913bbaf * Revert r19796 for now. 2010-02-04 00:12:57 +00:00
Eelco Dolstra c45de33c67 * Respect @sysconfdir@. 2010-02-03 21:13:37 +00:00
Eelco Dolstra d0c32dc135 * In the build hook, if connecting to a machine fails, try the other
machines of the right type (if available).  This makes the build
  farm more robust to failures.
2010-02-03 20:35:37 +00:00
Eelco Dolstra f56a039775 * Use SSH connection sharing in the remote build script.
* Removed the Cygwin password hack since the problem is apparently
  fixed in Visual Studio.
2010-02-03 20:12:18 +00:00
Eelco Dolstra bc1e478db1 * nix-copy-closure: start only one SSH connection to the server, or
recycle an already existing connection (using  OpenSSH's connection
  sharing feature).
2010-02-03 15:34:52 +00:00
Eelco Dolstra e839802720 * Don't do a chdir to $tmpDir. It's not necessary, and Windows doesn't
support deleting the current directory.
2010-02-02 15:29:18 +00:00
Eelco Dolstra 50e34891f0 * Disable gzip compression in build-remote.pl because it puts too much
load on the Hydra build farm (where it's unnecessary anyway because
  it has a fast connection to the build machines).  In any case,
  compression can be enabled by using the `-C' option to ssh.
2010-01-25 16:14:45 +00:00
Eelco Dolstra 7ca9972636 * When doing a nix-pull, remove old manifests downloaded from the same
URL.  This prevents lots of old cruft accumulating in
  /nix/var/nix/manifests.
2009-12-09 19:36:54 +00:00
Eelco Dolstra c4c84d1edb * nix-build: be less verbose. 2009-12-09 18:08:28 +00:00
Eelco Dolstra 997db91e07 * Don't pass -K. It should really inherit the setting of the calling
Nix though.
2009-11-17 16:22:39 +00:00
Eelco Dolstra 3392d32e8b * In nix-pull/nix-channel, create the manifests directory if it
doesn't exist.  The Debian packages don't include the manifests
  directory, so nix-channel would silently skip doing a nix-pull,
  resulting in everything being built from source.  Thanks to Juan
  Pedro Bolívar Puente.
2009-11-13 10:08:31 +00:00
Eelco Dolstra e1df4ef73c 2009-09-17 17:02:14 +00:00
Eelco Dolstra 86408b3f47 * build-remote.pl: Pick machines in a round-robin order, rather than
giving jobs to the first machine until it hits its job limit, then
  the second machine and so on.  This should improve utilisation of
  the Hydra build farm a lot.  Also take an optional speed factor
  into account to cause fast machines to be preferred over slower
  machines with a similar load.
2009-09-17 15:48:17 +00:00
Eelco Dolstra 57e0d73c77 * build-remote.pl: allow the system type to be a comma-separated list
of system types.  Don't treat the x86_64-linux system type
  specially.
2009-09-17 13:51:04 +00:00
Eelco Dolstra 20b6f94b65 * nix-build: pass the --show-trace flag. 2009-07-15 09:10:38 +00:00
Eelco Dolstra f24cf5d303 * nix-build: if nix-instantiate or nix-store fails due to a signal
(e.g. out of memory or a segfault), print an error message.
  Otherwise the user doesn't see anything.
2009-06-10 11:30:34 +00:00
Eelco Dolstra c710fe540e * Machines of type x86_64-linux can do i686-linux builds. 2009-04-21 12:42:47 +00:00
Eelco Dolstra 0460ea4c39 * Cleanup. 2009-04-16 09:27:33 +00:00
Eelco Dolstra 096affb55b * Update the mtime on the lock file to make it easy to see when a slot
was last used.
2009-03-29 18:40:44 +00:00
Eelco Dolstra 737423a89c * Use polling to wait for a remote build slot when using a build hook
(that is, call the build hook with a certain interval until it
  accepts the build).
* build-remote.pl was totally broken: for all system types other than
  the local system type, it would send all builds to the *first*
  machine of the appropriate type.
2009-03-29 18:00:45 +00:00
Eelco Dolstra 47706e3924 * nix-copy-closure: compute the closure in one call to nix-store,
which is much faster.
2009-03-28 21:10:29 +00:00
Eelco Dolstra 3a2bbe7f8a * Simplify communication with the hook a bit (don't use file
descriptors 3/4, just use stdin/stderr).
2009-03-28 19:29:55 +00:00
Eelco Dolstra 7fb548aa26 * Clean up the output a bit. 2009-03-28 16:12:46 +00:00
Eelco Dolstra 7e05b8b75e * Future proofing: assume we can read manifests up to version 10
(which should therefore be backwards compatible).
2009-03-19 10:02:02 +00:00
Eelco Dolstra b88460bcbc * Disregard the Hash field in manifests. 2009-03-19 09:47:34 +00:00
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,
  and that they are all in the input closure (otherwise remote builds
  might fail, for example).  This is ensured at instantiation time by
  adding all derivations and their sources to inputDrvs and inputSrcs.
2009-03-18 17:36:42 +00:00
Eelco Dolstra 1dcf208f56 * Clean up some tests (use nix-build where appropriate). 2009-03-18 13:15:55 +00:00
Eelco Dolstra 1273d355ac * nix-install-package: don't pollute /nix/var/nix/manifests. 2009-02-27 14:06:38 +00:00
Eelco Dolstra d4ca5c3952 * Use the regular progress bar; the hash bar isn't very useful when
the size of the download isn't known in advance.
2009-02-27 13:55:11 +00:00
Eelco Dolstra fd2e14b3c8 * nix-build: support --option. 2009-02-27 12:09:30 +00:00
Eelco Dolstra 8ab6bc5a49 * nix-channel: use nix-build. 2009-02-27 11:01:03 +00:00
Eelco Dolstra f052c10eed * Check the manifest version. 2009-02-27 09:53:58 +00:00
Eelco Dolstra a7cee528c5 * Handle base-16 hashes in manifests. 2009-02-26 21:12:35 +00:00
Eelco Dolstra 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.

Michael Raskin 621093cb1c Replace wrong (w.r.t. PATH) sed call with in-shell substitution 2009-02-19 20:46:45 +00:00
Eelco Dolstra 1bb0f1e84b * Build hook: compress the transferred data. 2009-02-03 10:34:15 +00:00
Eelco Dolstra b682fae9d9 * Build hooks: use nix-store --import. This prevents a redundant
scan for runtime dependencies (i.e. the local machine shouldn't do a
  scan that the remote machine has already done).  Also pipe directly
  into `nix-store --import': don't use a temporary file.
2009-02-02 17:24:10 +00:00
Eelco Dolstra 019176137f * When using a build hook, distinguish between transient failures
(e.g. an SSH connection problem) and permanent failures (i.e. the
  builder failed).  This matters to Hydra (it wants to know whether it
  makes sense to retry a build).
2009-01-13 11:39:09 +00:00
Eelco Dolstra 4ce692df88 2009-01-13 10:42:13 +00:00
Eelco Dolstra d91dc086bb 2008-12-04 16:51:36 +00:00
Eelco Dolstra 9ac3f5df9c * Propagate --max-silent-time to remote machines. 2008-12-04 16:51:16 +00:00
Eelco Dolstra bcfe98acff * Prefer building on a remote machine over a local machine. This
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.
2008-12-04 14:29:41 +00:00
Eelco Dolstra 5dfba0b4db * Force allocation of a pseudo-terminal to clean up the remote
nix-store process when the connection is interrupted.
2008-12-04 13:36:52 +00:00
Eelco Dolstra 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.
2008-12-04 12:20:06 +00:00
Eelco Dolstra 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.
2008-12-04 10:40:41 +00:00
Eelco Dolstra 6bbff48079 2008-11-20 17:22:42 +00:00
Eelco Dolstra 4213b8d8ec * Urgh. 2008-11-20 15:44:59 +00:00
Eelco Dolstra 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.)
2008-11-19 23:26:19 +00:00
Eelco Dolstra fa791116a3 * Get rid of nix-pack-closure / nix-unpack-closure, they're redundant. 2008-11-18 14:43:40 +00:00
Eelco Dolstra 2b2aa8a820 * Doh. 2008-09-08 11:02:15 +00:00
Michael Raskin 2a01d06da6 Added nix-http-export.cgi to extra distributed scripts; so it can be installed from releases, not only from SVN. 2008-08-29 08:34:38 +00:00
Michael Raskin 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.
2008-08-06 19:43:53 +00:00
Eelco Dolstra 7592f48c83 * nix-build: `--dry-run' flag. 2008-08-04 13:46:01 +00:00
Eelco Dolstra 42043953c3 * Doh. 2008-08-04 13:15:47 +00:00
Michael Raskin b3c26180e3 Updates to nix-reduce-build: only realize fixed derivations if user asks so, or only use substituters. Oh, and add possibility to use : for things like /etc/nixos/nixpkgs:-A:gnused 2008-08-02 16:43:25 +00:00
Eelco Dolstra 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
  paths.)  This required some refactoring: the substituter programs
  are now kept running and receive/respond to info requests via
  stdin/stdout.
2008-08-02 12:54:35 +00:00
Eelco Dolstra 096198d11f * A quick hack to make nix-prefetch-url support mirror:// URLs. It
requires that $NIXPKGS_ALL points at a Nixpkgs tree.
2008-07-23 16:02:58 +00:00
Eelco Dolstra 660244f65f * Make sure that copy-from-other-stores.pl is built. 2008-07-23 09:38:38 +00:00
Eelco Dolstra 989176c56e * Allow read-only access to the store (e.g., non-root users on NixOS
can do operations like "nix-store -qR <path>" even without the Nix
  daemon).
2008-07-18 15:34:46 +00:00
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.
2008-07-12 18:58:24 +00:00

Michael Raskin 18e27629d3 Added local best-effort builds (i.e. one failure does not ruin all packages you would like to see built) 2008-06-14 08:30:35 +00:00
Michael Raskin 194c66eeeb Stupid error in script 2008-06-13 14:34:19 +00:00
Michael Raskin f903d86740 OK, I will believe that fix does no worse.. 2008-06-13 13:53:14 +00:00
Michael Raskin ce85b55cf0 Updated help text 2008-06-12 17:45:38 +00:00
Michael Raskin 4532e4b90d Added verbosity for nix-reduce-build 2008-06-12 16:26:53 +00:00
Michael Raskin 9819bb20da Added support for file:// archive (.nar.gz) repositories to nix-reduce-build. /tmp/nix-export created by nix-http-export.cgi is OK. 2008-05-11 15:54:30 +00:00

Eelco Dolstra f106868110 * Cleanup. 2008-03-20 10:16:36 +00:00
Eelco Dolstra d7caac3e81 * Don't install nix-reduce-build by default yet please, I first want
to understand better what it does...
2008-02-28 21:27:47 +00:00
Michael Raskin 11d512e7a8 Added nix-reduce-build. You point it to some path you want to build and it fetches whatever it can from specified computers via nix-copy-closure. NOTE: You do want to set up RSA keys or ssh-agent or something... You really do want it. It will run separate ssh instances insane number of times. 2008-02-27 21:26:47 +00:00
Eelco Dolstra de012e76e2 * Don't use "store expression", it's obsolete. 2007-12-30 23:35:45 +00:00
Eelco Dolstra c370755583 * Flag `--no-build-hook' to disable distributed builds.
* queryDeriver in daemon mode: don't barf if the other side returns an
  empty string (which means there is no deriver).
2007-11-16 16:15:26 +00:00

Eelco Dolstra bfec245efa * Add build-remote.pl to the Nix distribution. 2007-11-15 14:28:08 +00:00
Eelco Dolstra 5b74a59570 * nix-prefetch-url: don't fail if /tmp/nix-prefetch-url-<pid> exists,
instead use a counter just like we do for temporary build
  directories.

Eelco Dolstra f8ed2e64a5 2007-10-22 12:05:18 +00:00
Eelco Dolstra 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).
2007-10-09 22:14:27 +00:00
Eelco Dolstra 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".)
2007-09-17 16:08:24 +00:00
Eelco Dolstra 9441550acb * nix-push / generate-patches: bzip the manifest. 2007-09-04 15:38:09 +00:00
Eelco Dolstra 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.)
2007-08-22 14:52:22 +00:00
Eelco Dolstra dbc0170ed9 * Show errors in nix-prefetch-url. 2007-08-15 09:24:06 +00:00
Eelco Dolstra ffa1c61cd5 * Fix the tests. 2007-08-14 13:15:59 +00:00
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).
2007-08-12 00:29:28 +00:00
Eelco Dolstra 4695f4edd6 * nix-pull: support bzipped manifests: when doing a nix-pull on $url,
try $url.bz2 first.
2007-08-10 01:42:00 +00:00
Eelco Dolstra 911bc01454 * Enable nix-prefetch-url caching in nix-channel. 2007-08-10 00:28:44 +00:00
Eelco Dolstra 5e52df18fe * Don't rely on /dev/stdin. 2007-08-10 00:22:21 +00:00
Eelco Dolstra c5e934dcc9 * nix-pull: using nix-prefetch-url (so that we get caching for free),
and store the manifests in the Nix store.  (So now
  /nix/var/nix/manifests/ just contains symlinks to the store and is
  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.
2007-08-09 23:16:44 +00:00
Eelco Dolstra 9bff7ad728 * Check against creation of GC roots in the store. Those roots don't
work, because findRoots() stops when it encounters a symlink to the
  store.  And of course the store is supposed to be read-only.
2007-06-11 11:36:22 +00:00
Eelco Dolstra f3ebd03bb1 * Remove debug statement. 2007-06-04 12:03:33 +00:00
Eelco Dolstra 34d4c9388b 2007-05-02 16:06:04 +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 4caca58ff7 * Make the maximum patch size configurable. 2007-03-30 09:01:05 +00:00
Eelco Dolstra efd31139df * Forgot a @bindir@. 2007-03-27 09:53:58 +00:00
Eelco Dolstra d303b389a9 * `nix-copy-closure --from': copy from a remote machine instead of to
a remote machine.
2007-03-26 21:05:17 +00:00
Eelco Dolstra 7edd2e2cd2 * Refactoring. 2007-03-26 20:49:22 +00:00
Eelco Dolstra a8ea4cbcc8 * Scan /proc/sys/kernel/modprobe for roots to prevent the kernel
modules for the running kernel from being garbage-collected.  Idem
  for /proc/sys/kernel/fbsplash.
2007-03-20 11:13:15 +00:00
Eelco Dolstra eb2dd4815c * Remove old generations in all directories under
/nix/var/nix/profiles, not just in that directory itself.  (NixOS
  puts profiles in /nix/var/nix/profiles/per-user.)
2007-03-13 11:30:57 +00:00
Eelco Dolstra df0283ae86 * Get rid of those stupid --login tricks, it's the responsibility of
the remote system to make sure that Nix is in the $PATH.
2007-03-01 13:55:47 +00:00
Eelco Dolstra 30394a4f3f * sh -> bash. 2007-03-01 13:49:20 +00:00
Eelco Dolstra 363e307fd3 * Error message to stdout. 2007-02-26 23:32:10 +00:00
Eelco Dolstra fa2be32034 * nix-copy-closure: force a login shell on the remote machine to make
sure that nix-store is in the PATH.
* nix-copy-closure: option --gzip to compress data.
2007-02-22 16:42:01 +00:00
Eelco Dolstra 4c5e6d1a2f * nix-copy-closure: option --sign.
* nix-copy-closure: set SSH options through NIX_SSHOPTS..
2007-02-22 15:48:20 +00:00
Eelco Dolstra 024a8ed382 * New command `nix-copy-closure' to copy a closure to a Nix store on
another machine through ssh.  E.g.,

    $ nix-copy-closure xyzzy $(which svn)

  copies the closure of Subversion to machine `xyzzy'.  This is like
  `nix-pack-closure $(which svn) | ssh xyzzy', but it's much more
  efficient since it only copies those paths that are missing on the
  target machine.
2007-02-21 23:14:53 +00:00
Eelco Dolstra 8181a1c3bb * Close the file - just in case. 2007-02-20 22:49:08 +00:00
Eelco Dolstra bae75ca5a1 * New kind of manifest object: "localPath", which denotes that a store
path can be created by copying it from another location in the file
  system.  This is useful in the NixOS installation.
2007-01-23 16:50:19 +00:00
Eelco Dolstra 36d9258c0d * Successors have been gone for ages. 2007-01-23 16:05:59 +00:00
Eelco Dolstra 7bc30e1ca8 * nix-prefetch-url: change the default hash to SHA-256 (in base-32). 2007-01-22 09:53:36 +00:00
Eelco Dolstra afe23b5f38 * nix-pack-closure: store the top-level store paths in the closure.
* nix-unpack-closure: extract the top-level paths from the closure and
  print them on stdout.  This allows them to be installed, e.g.,
  "nix-env -i $(nix-unpack-closure)".  (NIX-64)
2007-01-13 19:50:42 +00:00
Eelco Dolstra 215505bb46 * Removed chroot support. 2007-01-13 17:54:01 +00:00
Eelco Dolstra 1b7840b949 2007-01-11 19:28:28 +00:00
Eelco Dolstra 69c8b5b8a7 * Install generate-patches into libexec. 2007-01-11 16:19:45 +00:00
Eelco Dolstra 1f3722bd4a * Reject patches that are larger than a certain fraction of the full archive
(currently 60%).  Large patches aren't very economical.
2007-01-08 15:32:15 +00:00
Eelco Dolstra 50bdec410a * Huge speedup in patch propagation (20 minutes or so to 3 seconds). 2007-01-08 15:17:18 +00:00
Eelco Dolstra cafaceb707 * Handle weird cases when the server redirects us while setting a cookie. 2006-12-15 21:27:26 +00:00
Eelco Dolstra 9dbfe242e3 * Kill a build if it has gone for more than a certain number of
seconds without producing output on stdout or stderr (NIX-65).  This
  timeout can be specified using the `--max-silent-time' option or the
  `build-max-silent-time' configuration setting.  The default is
  infinity (0).

* Fix a tricky race condition: if we kill the build user before the
  child has done its setuid() to the build user uid, then it won't be
  killed, and we'll potentially lock up in pid.wait().  So also send a
  conventional kill to the child.
