0243eea4b9 * Create a symlink to /nix/var/nix/manifests in /nix/var/nix/gcroots 
if it doesn't exist.

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).

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.

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.

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.

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).

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.

1e7e4f21ba * Remove the localPaths feature in manifests since it's no longer used 
and redundant anyway.
 2011-04-06 09:16:22 +00:00

0423d0692a * Print a better error message. 2011-03-16 15:55:57 +00:00

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.

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

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.

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

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

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.
