Eelco Dolstra 917e06bf63 * Delete the output paths before invoking the build hook. 2007-03-07 15:53:11 +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 db1973d012 * Look for the openssl program at compile time. If not found, call
openssl through $PATH at runtime.

Eelco Dolstra b4a040e52b * Don't check the signature unless we have to. 2007-03-01 12:30:24 +00:00
Eelco Dolstra 2ea3bebc23 * Doh! The deriver can be empty. 2007-02-27 23:18:57 +00:00
Eelco Dolstra 044b6482c1 * Greatly reduced the amount of stack space used by the Nix expression
evaluator.  This was important because the NixOS expressions started
  to hit 2 MB default stack size on Linux.

  GCC is really dumb about stack space: it just adds up all the local
  variables and temporaries of every scope into one huge stack frame.
  This is really bad for deeply recursive functions.  For instance,
  every `throw Error(format("error message"))' causes a format object
  of a few hundred bytes to be allocated on the stack.  As a result,
  every recursive call to evalExpr2() consumed 4680 bytes.  By
  splitting evalExpr2() and by moving the exception-throwing code out
  of the main functions, evalExpr2() now only consumes 40 bytes.
  Similar for evalExpr().

Eelco Dolstra adce01a8d0 * When NIX_SHOW_STATS=1, show the amount of stack space consumed by
the Nix expression evaluator.
2007-02-27 17:28:51 +00:00
Eelco Dolstra 363e307fd3 * Error message to stdout. 2007-02-26 23:32:10 +00:00
Eelco Dolstra ddde8e2f32 * Handle EINTR in select(). 2007-02-22 18:15:29 +00:00
Eelco Dolstra 27bb0ac7d2 * /man -> /share/man 2007-02-22 17:00:58 +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.

Eelco Dolstra 7f6161ab3a * Flush cout to show progress. 2007-02-21 23:08:55 +00:00
Eelco Dolstra 0db450024d * Export/import many paths in one go. 2007-02-21 23:00:31 +00:00
Eelco Dolstra 9da367b7d5 * `nix-store -qR' and friends: print the paths sorted topologically
under the references relation.  This is useful for commands that
  want to copy paths to another Nix store in the right order.
2007-02-21 22:45:10 +00:00
Eelco Dolstra 881feb9698 * Flag --print-invalid' in nix-store --check-validity' to print out
which paths specified on the command line are invalid (i.e., don't
  barf when encountering an invalid path, just print it).  This is
  useful for build-remote.pl to figure out which paths need to be
  copied to a remote machine.  (Currently we use rsync, but that's
  rather inefficient.)
2007-02-21 17:57:59 +00:00
Eelco Dolstra 65f195f4c7 * Check that the file containing the secret key is secret. 2007-02-21 17:51:10 +00:00
Eelco Dolstra bdadb98de8 * `nix-store --import' now also works in remote mode. The worker
always requires a signature on the archive.  This is to ensure that
  unprivileged users cannot add Trojan horses to the Nix store.
2007-02-21 17:34:02 +00:00
Eelco Dolstra 0f5da8a83c * Support exportPath() in remote mode. 2007-02-21 16:34:00 +00:00
Eelco Dolstra dc7d594776 * importPath(): set the deriver.
* exportPath(): lock the path, use a transaction.
2007-02-21 16:23:25 +00:00
Eelco Dolstra 43c4d18c6a * nix-store --import': import an archive created by nix-store
--export' into the Nix store, and optionally check the cryptographic
  signatures against /nix/etc/nix/signing-key.pub.  (TODO: verify
  against a set of public keys.)
2007-02-21 15:45:32 +00:00
Eelco Dolstra 46e0919ced * `nix-store --export --sign': sign the Nix archive using the RSA key
in /nix/etc/nix/signing-key.sec
2007-02-21 14:31:42 +00:00
Eelco Dolstra 6c9fdb17fb * Don't use $SHELL. 2007-02-21 14:00:46 +00:00
Eelco Dolstra b824a1daee * Start of `nix-store --export' operation for serialising a store
path.  This is like `nix-store --dump', only it also dumps the
  meta-information of the store path (references, deriver).  Will add
  a `--sign' flag later to add a cryptographic signature, which we
  will use for exchanging store paths between build farm machines in a
  secure manner.
2007-02-20 23:17:20 +00:00
Eelco Dolstra 3390c1be76 * Temporary notes on how we're going to use OpenSSL. 2007-02-20 22:57:46 +00:00
Eelco Dolstra 8181a1c3bb * Close the file - just in case. 2007-02-20 22:49:08 +00:00
Eelco Dolstra 46605fb4f5 * Fix 64-bit compiler warnings. 2007-02-06 20:03:53 +00:00
Eelco Dolstra 52d03276dd * Compatibility with docbook5-xsl. 2007-02-05 12:10:10 +00:00
Eelco Dolstra 451dbf687f * nix-env now maintains meta info (from the `meta' derivation
attribute) about installed packages in user environments.  Thus, an
  operation like `nix-env -q --description' shows useful information
  not only on available packages but also on installed packages.

* nix-env now passes the entire manifest as an argument to the Nix
  expression of the user environment builder (not just a list of
  paths), so that in particular the user environment builder has
  access to the meta attributes.
  
* New operation `--set-flag' in nix-env to change meta info of
  installed packages.  This will be useful to pass per-package
  policies to the user environment builder (e.g., how to resolve
  collision or whether to disable a package (NIX-80)) or upgrade
  policies in nix-env (e.g., that a package should be "masked", that
  is, left untouched by upgrade actions).  Example:

  $ nix-env --set-flag enabled false ghc-6.4
2007-02-02 01:52:42 +00:00
Eelco Dolstra f52de527c7 * Doh! 2007-01-29 15:55:49 +00:00
Eelco Dolstra b618fa6eb6 * computeStorePathForText: take the references into account when
computing the store path (NIX-77).  This is an important security
  property in multi-user Nix stores.

  Note that this changes the store paths of derivations (since the
  derivation aterms are added using addTextToStore), but not most
  outputs (unless they use builtins.toFile).
2007-01-29 15:51:37 +00:00
Eelco Dolstra c558b1583c * Don't capitalise the primop functions. 2007-01-29 15:15:37 +00:00
Eelco Dolstra 18e6096105 * Organise primops.cc a bit better. 2007-01-29 15:11:32 +00:00
Eelco Dolstra 7349bd0176 New primitives:
* `sub' to subtract two numbers.
* `stringLength' to get the length of a string.
* `substring' to get a substring of a string.  These should be enough
  to allow most string operations to be expressed.
2007-01-29 14:23:09 +00:00
Eelco Dolstra 7dedbd896a * filterSource: pass strings to the predicate function instead of
paths.  Paths can have unexpected semantics.
2007-01-29 13:32:50 +00:00
Eelco Dolstra 84a84afb0e * Nasty: Glibc clears the TMPDIR environment variable in setuid
programs, so if a builder uses TMPDIR, then it will fail when
  executed through nix-setuid-helper.  In fact Glibc clears a whole
  bunch of variables (see sysdeps/generic/unsecvars.h in the Glibc
  sources), but only TMPDIR should matter in practice.  As a
  workaround, we reinitialise TMPDIR from NIX_BUILD_TOP.
2007-01-24 13:31:20 +00:00
Eelco Dolstra fac63d6416 * exportReferencesGraph: work on paths within store paths as well. 2007-01-23 16:57:43 +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 71ceb1c161 * Handle multiple indirect symlinks when loading a Nix expression. 2007-01-15 14:50:25 +00:00
Eelco Dolstra e4b0666f8e * builtins.filterSource: pass the type of the file ("regular",
"directory", "symlink") as the second argument to the filter
  predicate.
2007-01-15 08:54:51 +00:00
Eelco Dolstra 63f3ce6d9a * `nix-store --verify': revive checking the referrers table. This is
important to get garbage collection to work if there is any
  inconsistency in the database (because the referrer table is used to
  determine whether it is safe to delete a path).
* `nix-store --verify': show some progress.
2007-01-14 17:28:30 +00:00
Eelco Dolstra 8f67b35886 * Make the garbage collector more resilient to certain consistency
errors: in-use paths now cause a warning, not a fatal error.
2007-01-14 16:24:49 +00:00
Eelco Dolstra 8659edc098 * Don't forget the .flags files. 2007-01-14 12:33:04 +00:00
Eelco Dolstra e418976107 * Option --argstr for passing string arguments easily. (NIX-75) 2007-01-14 12:32:44 +00:00
Eelco Dolstra 4e329f173f * Doh. 2007-01-14 12:16:58 +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)
