Eelco Dolstra 83075304e5 * Don't make the builder executable. 2003-07-30 09:49:47 +00:00
Eelco Dolstra 1cb030736e * Bug: Fix does not allow empty names, so don't generate them. 2003-07-29 17:56:39 +00:00
Eelco Dolstra a01629894d * Use `--query --requisites' and include successors when pushing. Don't
use `--query --generators' anymore.
2003-07-29 15:19:03 +00:00
Eelco Dolstra 40f32ae00a * Typo: if -> elsif. 2003-07-29 14:42:14 +00:00
Eelco Dolstra 8846465934 * Get garbage collection and cache population to work *properly*.
Renamed `fstateRefs' to `fstateRequisites'.  The semantics of this
  function is that it returns a list of all paths necessary to realise
  a given expression.  For a derive expression, this is the union of
  requisites of the inputs; for a slice expression, it is the path of
  each element in the slice.  Also included are the paths of the
  expressions themselves.  Optionally, one can also include the
  requisites of successor expressions (to recycle intermediate
  results).

* `nix-switch' now distinguishes between an expression and its normal
  form.  Usually, only the normal form is registered as a root of the
  garbage collector.  With the `--source-root' flag, it will also
  register the original expression as a root.

* `nix-collect-garbage' now has a flag `--keep-successors' which
  causes successors not to be included in the list of garbage paths.

* `nix-collect-garbage' now has a flag `--invert' which will print all
  paths that should *not* be garbage collected.

Eelco Dolstra dc14a3de46 * Nicer dot graphs. 2003-07-29 10:53:27 +00:00
Eelco Dolstra 79ba0431db * `fstateRefs' now works on derive expressions as well. TODO: make
this more efficient.
* A flag `-n' in 'nix --query' to normalise the argument.  Default is
  not to normalise.
2003-07-29 10:43:12 +00:00
Eelco Dolstra 5acb45446e * Let `nix --install' print out the id of the normal form.
* Some minor refactoring.
2003-07-29 09:45:03 +00:00
Eelco Dolstra ce5fd1cc12 * Do not set LD_LIBRARY_PATH; it breaks many things. E.g., SuSE's ssh
dynamically links against libdb4 (?!), due to LD_LIBRARY_PATH it picks 
  up our libdb4 instead of SuSE's libdb4, but our libdb4 uses another 
  glibc so loading barfs.

  Instead, all packages should use rpaths to store library locations in
  executables/libraries.  The disadvantage is that overriding rpaths is 
  harder.  (It is possible by invoking the dynamic linker directly, e.g., 
  `/lib/ld-linux.so.2 --ignore-path LIST program args...' to ignore the 
  rpath for the libraries in LIST).  It would be better to use DT_RUNPATH, 
  which is consulted by the dynamic linker *after* LD_LIBRARY_PATH but 
  *before* ld.so.cache and the system directories.

Eelco Dolstra dec8fbc52b * Check for the pthread library (db4 needs it on some platforms). 2003-07-28 14:13:42 +00:00
Eelco Dolstra 949c4fa1a8 * `nix --help'.
* `nix --query --graph' to print a dot dependency graph of derive
  expressions.
2003-07-28 12:19:23 +00:00
Eelco Dolstra f21b341957 * Fix message. 2003-07-24 15:03:36 +00:00
Eelco Dolstra 5d7a20dac3 * Prevent spurious rebuilds of db/aterm. 2003-07-24 14:31:39 +00:00
Eelco Dolstra 0a0c1fcb4d * The `-v' flag no longer takes an argument; it should be repeated
instead (e.g., `-vvvv' for lots of output).  Default is to only
  print error messages.
2003-07-24 13:43:16 +00:00
Eelco Dolstra 3b521bb1bd * Do sync the database, since not doing so caused database changes not
to reach the disk at all.  Looks like a bug.
2003-07-24 13:35:17 +00:00
Eelco Dolstra 1a7468a57a * Debug levels. Use `--verbose / -v LEVEL' to display only messages
up to the given verbosity levels.  These currently are:

    lvlError = 0, 
    lvlNormal = 5,
    lvlDebug = 10,
    lvlDebugMore = 15

  although only lvlError and lvlDebug are actually used right now.
2003-07-24 08:53:43 +00:00
Eelco Dolstra b75719b984 * Don't sync the database on close. This was killing performance.
(Of course, the real problem is that we open the database for
  *every* operation; we should only open it once.  And we should use
  transactions.)
2003-07-24 08:24:32 +00:00
Eelco Dolstra 39ce70025b * Incorporated Berkeley DB and ATerm into the source tree.
* `make dist'.
2003-07-23 15:53:34 +00:00
Eelco Dolstra 9202570f8c * libdb_cxx-4 -> libdb_cxx 2003-07-22 20:02:33 +00:00
Eelco Dolstra e877c69d78 * Substitutes now should produce a path with the same id as they are
substituting for (obvious, really).

* For greater efficiency, nix-pull/unnar will place the output in a
  path that is probably the same as what is actually needed, thus
  preventing a path copy.

* Even if a output id is given in a Fix package expression, ensure
  that the resulting Nix derive expression has a different id.  This
  is because Nix expressions that are semantically equivalent (i.e.,
  build the same result) might be different w.r.t. efficiency or
  divergence.  It is absolutely vital for the substitute mechanism
  that such expressions are not used interchangeably.
2003-07-22 15:15:15 +00:00
Eelco Dolstra df648c4967 * nix --query --expansion' (-qe') to get any path with content
corresponding to the given id.
2003-07-22 10:24:22 +00:00
Eelco Dolstra d84931ee56 * Changed nix-pull to match nix-push. 2003-07-21 22:05:19 +00:00
Eelco Dolstra c7bdb76fe4 * Syntax fixes.
* When pushing, put the hash in the file name so that the 
  client can verify (proof-carrying file names?).
2003-07-21 21:34:56 +00:00
Eelco Dolstra d5ee6f8700 * In `--query --generators', print out paths, not ids.
(There should really be a switch for this).
2003-07-21 21:31:03 +00:00
Eelco Dolstra 2616e6a6f3 * Check for errors. 2003-07-21 20:58:34 +00:00
Eelco Dolstra 9f4ad99e92 * Canonicalise path. 2003-07-21 20:58:21 +00:00
Eelco Dolstra 249988a787 * Allow the output/expression id to be forced to a certain
value; this potentially dangerous feature enables better 
  sharing for those paths for which the content is known in 
  advance (e.g., because a content hash is given).
* Fast builds: if we can expand all output paths of a derive 
  expression, we don't have to build.
2003-07-21 20:07:12 +00:00
Eelco Dolstra 49231fbe41 * Changes to the command line syntax of Nix.
* A function to find all Nix expressions whose output ids are
  completely contained in some set.  Useful for uploading relevant Nix
  expressions to a shared cache.
2003-07-21 14:46:01 +00:00
Eelco Dolstra 401452e57a * Memoize the evaluation of Fix expressions to speed up computation. 2003-07-21 08:55:49 +00:00
Eelco Dolstra 7984cfc7c1 * Argh, another short-write problem. Added wrappers around
read()/write() to fix this once and for all.
2003-07-20 21:11:43 +00:00
Eelco Dolstra 667a6afb9d * Remove accidentally added file. 2003-07-20 19:30:53 +00:00
Eelco Dolstra 6f1a0f948d * Refactorings. 2003-07-20 19:29:38 +00:00
Eelco Dolstra ab350eafd2 * Generate nar.sh, fetchurl.sh. 2003-07-18 07:42:57 +00:00
Eelco Dolstra b3fc38bf6a * For debugging: `nix --verify' to check the consistency of the
database and store.
2003-07-17 12:27:55 +00:00
Eelco Dolstra 71cc3ceae5 * Preserve the executable bit. 2003-07-17 11:25:14 +00:00
Eelco Dolstra 54664b6fb7 * The write() system call can write less than the requested
number of bytes, e.g., in case of a signal like SIGSTOP.  
  This caused `nix --dump' to fail sometimes.

  Note that this bug went unnoticed because the call to `nix 
  --dump' is in a pipeline, and the shell ignores non-zero 
  exit codes from all but the last element in the pipeline.  
  Is there any way to check the result of the initial elements
  in the pipeline?  (In other words, is it at all possible to 
  write reliable shell scripts?)
2003-07-16 21:24:02 +00:00
Eelco Dolstra 335aa1c35d * Doh! 2003-07-16 20:49:59 +00:00
Eelco Dolstra 6822fd7bf4 * Bug fix: slices are transitive, so if we detect that an
input path is referenced in an output paths, we also have to 
  add all ids referenced by that input path.
* Better debug assertions to catch these sorts of errors.
2003-07-16 20:33:29 +00:00
Eelco Dolstra 9d56ca219f * Substitute fixes. 2003-07-16 20:00:51 +00:00
Eelco Dolstra b9ecadee6e * Fix the -qr query. 2003-07-16 11:05:59 +00:00
Eelco Dolstra c11bbcfd26 * Fix self-referential outputs.
* Fix -qp query.
2003-07-16 08:30:26 +00:00
Eelco Dolstra d41d085b77 * Get Fix and Nix to work again. 2003-07-15 22:28:27 +00:00
Eelco Dolstra 7b3f44e05b * The new normaliser now passes the unit tests. 2003-07-15 21:24:05 +00:00
Eelco Dolstra f5b6fa5256 * Basic work on allowing derive expressions to build multiple paths.
This is not entirely trivial since this introduces the possibility
  of mutual recursion.
* Made normal forms self-contained.
* Use unique ids, not content hashes, for content referencing.
2003-07-15 16:28:54 +00:00
Eelco Dolstra 8898e86b4f * Get the garbage collector to work again. 2003-07-14 10:45:04 +00:00
Eelco Dolstra 3509299aca * After building, scan for actual file system references as
opposed to declared references.  This prunes the reference
  graph, thus allowing better garbage collection and more
  efficient derivate distribution.
2003-07-14 10:23:11 +00:00
Eelco Dolstra 135b7d54db * Don't check for staleness by default. 2003-07-13 21:43:57 +00:00
Eelco Dolstra e6363b05ae * Pass $(prefix) and other variables through -D..., not
through config.h, to prevent silly Autoconf problems.
2003-07-13 19:26:00 +00:00
Eelco Dolstra 9c620e4afa * Generate the scripts so that we can substitute the prefix
etc. correctly.
* Fixed nix-switch.
2003-07-13 18:58:03 +00:00
Eelco Dolstra 5304a1eb3a * Fetchurl: check md5 checksum. 2003-07-12 11:03:14 +00:00
