0a2de7f543 * Lam -> Function. Doh! 2003-08-14 09:29:07 +00:00

95b49f8044 * Manual updates. 2003-08-13 15:17:57 +00:00

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.

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).

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

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

37483672d4 * App -> Call. 
* Allow booleans in package environment bindings (True maps to "1",
  False maps to "").

b9c9b461ea * Made nix-push much faster. 2003-08-05 12:30:06 +00:00

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.

17f05dba77 * Allow the top-level expression to be a list of expressions that 
normalise to Nix expression.

d6b6b2d3a8 * Delete obstructed paths prior to building. 2003-08-05 09:47:20 +00:00

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.

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'.

9df93f30bd * Don't use substitutes in addToStore(). 2003-08-01 09:01:51 +00:00

06434072e7 * Put the database verifier in a transaction. 2003-07-31 19:49:11 +00:00
Eelco Dolstra
06d3d7355d * Enclose most operations that update the database in transactions. 
* Open all database tables (Db objects) at initialisation time, not
  every time they are used.  This is necessary because tables have to
  outlive all transactions that refer to them.

177a7782ae * Use a more reasonable log file size (256 KB instead of 10 MB). 
* Checkpoint on exit.

4a013962bd * Started using Berkeley DB environments. This is necessary for 
transaction support (but we don't actually use transactions yet).

aaee69cfde * INSTALL_DATA -> INSTALL_PROGRAM to ensure that the execute bit 
remains set.

83075304e5 * Don't make the builder executable. 2003-07-30 09:49:47 +00:00

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.

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.
