Eelco Dolstra 5bcdc7e351 * Update the cleanup script. 2011-08-27 16:59:32 +00:00
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.
2011-08-06 16:05:24 +00:00
Eelco Dolstra 0243eea4b9 * Create a symlink to /nix/var/nix/manifests in /nix/var/nix/gcroots
if it doesn't exist.
2011-07-20 11:47:00 +00:00
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.
2011-04-11 13:16:54 +00:00
Eelco Dolstra 08c8971498 * Lock the database during updates. 2011-04-11 12:40:13 +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 83252b4ca9 * Subtle bug: if you import File::stat in one module, it affects other
modules as well.  So use symbolic field names everywhere (which is
  nicer anyway).
2011-04-11 08:21:30 +00:00
Eelco Dolstra b1882c3ef7 * Create $manifestDir if it doesn't exist. 2011-04-11 08:06:14 +00:00
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.
2011-04-10 23:22:46 +00:00
Eelco Dolstra 1e7e4f21ba * Remove the localPaths feature in manifests since it's no longer used
and redundant anyway.
2011-04-06 09:16:22 +00:00
Eelco Dolstra 0423d0692a * Print a better error message. 2011-03-16 15:55:57 +00:00
Eelco Dolstra 802c2651c8 2011-02-17 15:08:33 +00:00
Eelco Dolstra e945b52a31 * nix-push: handle the case where the hash is not set in the DB. 2011-02-17 13:26:33 +00:00
Eelco Dolstra d6c8b995c5 * In Hydra manifests the Size field is missing, so don't rely on it.
This caused a lot of "Use of uninitialized value" warnings from
  Perl.
2010-12-22 10:32:32 +00:00
Eelco Dolstra a0be433fec * Disable X11 forwarding, it's not needed. 2010-12-15 14:25:54 +00:00
Eelco Dolstra f1a6b97639 * nix-copy-closure: make sure that the shell doesn't do globbing of
`+' and `?' in filenames.  This is very slow if /nix/store is very
  large.  (This is a quick hack - a cleaner solution would be to
  bypass the shell entirely.)
2010-12-15 08:39:37 +00:00
Eelco Dolstra d787285af9 * nix-instantiate: return exit status 100 to denote a permanent build
failure.  The build hook can use this to distinguish between
  transient and permanent failures on the remote side.
2010-12-13 16:53:23 +00:00
Eelco Dolstra 542fc69062 * When doing a query (e.g. `nix-store -r --dry-run'), don't make a lot
of expensive calls to `nix-store --check-validity'.
2010-12-13 08:39:10 +00:00
Eelco Dolstra 7d0444e244 * Bad things happen when a filehandle has the same name as a module. 2010-12-07 12:33:42 +00:00
Eelco Dolstra 365f3028dd * Use CamelCase for the Perl modules. 2010-12-05 17:50:29 +00:00
Eelco Dolstra f42a505ab7 * Add a script `nix-generate-patches'.
* Fix the binary patching test.
2010-12-05 17:36:02 +00:00
Eelco Dolstra d3bba0c2d8 * Move the patch generator into a module. 2010-11-29 15:26:28 +00:00
Eelco Dolstra 9737a7eba0 * Don't generate patches if the system type differs. 2010-11-29 09:26:05 +00:00
Eelco Dolstra bd48fd97f6 * Impose a configurable time limit on patch generation. This is
necessary because bsdiff has some pathological worst-case behaviour,
  e.g. O(n^2) on files consisting only of 0s.
2010-11-29 09:15:45 +00:00
Eelco Dolstra 1a211d812f * Oops. 2010-11-17 17:54:49 +00:00
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).
2010-11-17 17:41:59 +00:00
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.
