d645633643 nix-copy-closure: don't print copied path on stdout
We're already printing progress on stderr, so printing them on stdout
afterwards is kind of useless.

56042a120a build-remote.pl: don't wait forever for the upload lock
In the build hook, don't wait forever to get the upload lock.  This
ensures progress if another process gets stuck while holding the
upload lock.

ce86a9a0ae * nix-channel: fail if we don't have write permission to the manifests
directory.  Previously in this situation we did add the Nix
  expressions from the channel to allow installation from source, but
  this doesn't work for binary-only channels and leads to confusing
  error messages.

2a3f4110c5 * nix-build: put the temporary derivation symlink in a temporary
directory rather than the current directory.
* nix-build: --drv-link now implies --add-drv-link.

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.

48cea0d01e * Refactoring: Get rid of a few subdirectories in corepkgs/, and some
other simplifications.
* Use <nix/...> to locate the corepkgs.  This allows them to be
  overriden through $NIX_PATH.
* Use bash's pipefail option in the NAR builder so that we don't need
  to create a temporary file.

4d728bc3e6 * Security: make sure the lock files used by build-remote.pl are not
readable to other users.  Otherwise, any user can open the lock file
  for reading and lock it, thus DoSing the remote build mechanism.

69d6f0936a * Use a lock to ensure that only one build-remote instance can copy a
closure to a given machine at the same time.  This prevents the case
  where multiple instances try to copy the same missing store path to
  the target machine, which is very wasteful.

Eelco Dolstra
5bbd693cae * Add an API function exportPaths() that provides the functionality of
‘nix-store --export’.
* Add a Perl module that provides the functionality of
  ‘nix-copy-closure --to’.  This is used by build-remote.pl so it no
  longer needs to start a separate nix-copy-closure process.  Also, it
  uses the Perl API to do the export, so it doesn't need to start a
  separate nix-store process either.  As a result, nix-copy-closure
  and build-remote.pl should no longer fail on very large closures due
  to an "Argument list too long" error.  (Note that having very many
  dependencies in a single derivation can still fail because the
  environment can become too large.  Can't be helped though.)

f8e609c341 * nix-pull: update the Nix manifest cache if necessary. Also, don't
read the manifest just to check the version and print the number of
  paths.  This makes nix-pull very fast for the cached cache (speeding
  up nixos-rebuild without the ‘--no-pull’ or ‘--fast’ options).

d7d7910ba4 * Don't decompress the manifests in /nix/var/nix/manifest. This saves
disk space, and, since they're typically only decompressed once (to
  fill the manifest cache), doesn't make things slower.

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.

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.

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

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.

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.)

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.

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'.
