Eelco Dolstra a88144215c * Remove write permission from output paths after they have been built.
* Point $HOME to a non-existing path when building to prevent certain tools (such as 
  wget) from falling back on /etc/passwd to locate the home directory (which we 
  don't want them to look at since it's not declared as an input).

Eelco Dolstra 56b98c3857 * Some work on the introduction. 2003-08-22 11:29:20 +00:00
Eelco Dolstra 956801fcc2 * Use maps and sets in the FState data type. This ensures normalisation of
slices and derivations w.r.t. order of paths, slice elements, etc.
2003-08-20 14:11:40 +00:00
Eelco Dolstra 624c48260f * Change the abstract syntax of slices. It used to be that ids were used as
keys to reference slice elements, e.g.,

    Slice(["1ef7..."], [("/nix/store/1ef7...-foo", "1ef7", ["8c99..."]), ...])

  This was wrong, since ids represent contents, not locations.  Therefore we
  now have:

    Slice(["/nix/store/1ef7..."], [("/nix/store/1ef7...-foo", "1ef7", ["/nix/store/8c99-..."]), ...])

* Fix a bug in the computation of slice closures that could cause slice
  elements to be duplicated.

Eelco Dolstra 710175e6a0 * Bumped the version number to 0.3. 2003-08-20 11:31:15 +00:00
Eelco Dolstra ed0db2e0d8 * Fixed a serious bug in the computation of slices. Sometimes the slices
would not be properly closed under the path reference relation.

Eelco Dolstra 1472cc4825 * Pipe /dev/null into stdin. 2003-08-19 13:07:38 +00:00
Eelco Dolstra 2de8504791 * Delete the temporary directories of failed builds by default, and an
option `--keep-failed' to override this behaviour.
2003-08-19 09:04:47 +00:00
Eelco Dolstra 31e4aa6439 * Allow lists in package bindings, e.g.,
("srcs", [Relative("foo/bar.c"), Relative("foo/baz.h")])

  The result is an environment variable that contains the path names of the
  inputs separated by spaces (so this is not safe for values containing
  spaces).
2003-08-18 16:32:55 +00:00
Eelco Dolstra ebbb6ce578 * Most shells initialise PATH to some default (/bin:/usr/bin:...)
when PATH is not set.  We don't want this, so fill it in with
  some dummy value.
2003-08-18 14:54:54 +00:00
Eelco Dolstra c32e01eab2 * Revision 300!
* Put `@' in front of echo's in the Makefile.
2003-08-18 08:52:49 +00:00
Eelco Dolstra 08f9cfe267 * No longer automatically download Berkeley DB / ATerm. 2003-08-18 08:35:16 +00:00
Eelco Dolstra 96c7b98bf0 * Argument support in Fix. Arguments can be passed through the
builder using the `args' binding:

  ("args", ["bla", True, IncludeFix("aterm/aterm.fix")])

  Note that packages can also be declared as inputs by specifying them
  in the argument list.
2003-08-15 13:01:45 +00:00
Eelco Dolstra 555347744d * Derivation expressions now can specify arguments to be passed to the
builder.  Note that this unfortunately causes all Fix-computed
  hashes to change.
2003-08-15 12:32:37 +00:00
Eelco Dolstra e374dbf89b * A script `nix-prefetch-url' to fetch a URL, place it in the Nix
store, and print its hash.
2003-08-15 10:13:41 +00:00
Eelco Dolstra 01e30360d4 * Don't use a temporary file. 2003-08-15 09:39:33 +00:00
Eelco Dolstra 163db7367f * Fix can now read expressions from stdin (by saying `fix -'). 2003-08-15 09:21:19 +00:00
Eelco Dolstra 161aab582b * Use a catalog when calling xsltproc. 2003-08-14 18:24:40 +00:00
Eelco Dolstra a24cb19361 * Use xmllint instead of nsgmls to validate the manual. 2003-08-14 18:17:02 +00:00
Eelco Dolstra 9ee3b7a37a * Function application test cases. 2003-08-14 12:37:50 +00:00
Eelco Dolstra dc0ef2ca98 * Detect infinite loops using blackholing. 2003-08-14 12:37:31 +00:00
Eelco Dolstra 2e16ff22ac * Fix man page. 2003-08-14 11:27:02 +00:00
Eelco Dolstra 5cde23f869 * Function() takes a list of formals. 2003-08-14 09:49:31 +00:00
Eelco Dolstra 0a2de7f543 * Lam -> Function. Doh! 2003-08-14 09:29:07 +00:00
Eelco Dolstra 95b49f8044 * Manual updates. 2003-08-13 15:17:57 +00:00
Eelco Dolstra 68022552d2 * Put the pre-built manual and man pages in the tar distribution. 2003-08-13 15:17:36 +00:00
Eelco Dolstra c34a153ae5 * Documented the `--query' operation. 2003-08-13 10:45:01 +00:00
Eelco Dolstra b4f88d0ec3 * Split the book.xml into several xml files. 2003-08-13 09:13:52 +00:00
Eelco Dolstra 469f1eba56 * Documented some Nix operations. 2003-08-12 15:06:49 +00:00
Eelco Dolstra e405ca506e * Generate man pages from the manual. 2003-08-12 13:54:42 +00:00
Eelco Dolstra c602930e08 * deletePath(): some operating systems (e.g., Mac OS X) don't like it
when we delete entries from a directory while we are reading it.
  So read the directory into memory, then delete its contents.
2003-08-08 14:55:56 +00:00
Eelco Dolstra 4b7b0bd12c * Started on the introduction. 2003-08-07 15:27:14 +00:00
Eelco Dolstra 74867e72f2 * Start of manual; installation instructions. 2003-08-07 14:17:18 +00:00
Eelco Dolstra f8035d06f2 * Allow a name to be given to a system configuration through `--name
NAME'.  E.g., on the losser Subversion server, I do `nix-switch --name 
  svn $(fix ...)' to atomically upgrade the server (the SVN server 
  uses the Apache and Subversion installations in /nix/var/nix/links/svn).
2003-08-06 14:48:29 +00:00
Eelco Dolstra 9ad39df282 * `==' is not a valid operator. 2003-08-06 10:00:30 +00:00
Eelco Dolstra d551062ec4 * Scan for wget and use the full path in fetchurl.sh.
* Use nix-hash (not md5sum) in fetchurl.sh.
2003-08-06 09:35:05 +00:00
Eelco Dolstra 236eb59293 * Allow locks on paths to be acquired recursively (that is, if the
process is already holding a lock on a path, it may acquire the lock
  again without blocking or failing).  (This might be dangerous, not
  sure).  Necessary for fast builds to work.
2003-08-06 09:34:04 +00:00
Eelco Dolstra 720f06e3b0 * A flag `--flat' to just compute the MD5 checksum of the contents of
a regular file.  I.e., `nix-hash --flat' is equivalent to the
  coreutils `md5sum' command (which doesn't exist on all systems).
2003-08-06 09:06:32 +00:00
Eelco Dolstra 37483672d4 * App -> Call.
* Allow booleans in package environment bindings (True maps to "1",
  False maps to "").
2003-08-06 09:05:04 +00:00
Eelco Dolstra d34b4d4f28 * Conditionals. 2003-08-05 13:05:30 +00:00
Eelco Dolstra b9c9b461ea * Made nix-push much faster. 2003-08-05 12:30:06 +00:00
Eelco Dolstra 4ce652640b * Cache result of fstatePaths(). TODO: do this in fstore.cc. 2003-08-05 12:29:47 +00:00
Eelco Dolstra fd30f52cfc * Made nix-pull much faster by performing all Fix instantiations at
the same time.
2003-08-05 11:14:24 +00:00
Eelco Dolstra 17f05dba77 * Allow the top-level expression to be a list of expressions that
normalise to Nix expression.
2003-08-05 11:13:38 +00:00
Eelco Dolstra d6b6b2d3a8 * Delete obstructed paths prior to building. 2003-08-05 09:47:20 +00:00
Eelco Dolstra d2e963f7a3 * Path locking in addToStore() and expandPath(). 2003-08-04 07:09:36 +00:00
Eelco Dolstra c95b4ad290 * In normaliseFState(), wrap registration of the output paths and the
normal form in a single transaction to ensure that if we crash,
  either everything is registered or nothing is.  This is for
  recoverability: unregistered paths in the store can be deleted
  arbitrarily, while registered paths can only be deleted by running
  the garbage collector.
2003-08-01 15:41:47 +00:00
Eelco Dolstra d99d04e644 * Defensive programming against POSIX locking idiocy.
* Simplified realiseSlice().
2003-08-01 15:06:23 +00:00
Eelco Dolstra 545145cd58 * normaliseFState() now locks all output paths prior to building, thus
ensuring that simultaneous invocations of Nix don't clobber
  each other's  builds.

* Fixed a bug in `make install'.
2003-08-01 14:11:19 +00:00
Eelco Dolstra 9df93f30bd * Don't use substitutes in addToStore(). 2003-08-01 09:01:51 +00:00
