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
Eelco Dolstra 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.
 2003-07-31 16:05:35 +00:00
Eelco Dolstra 177a7782ae * Use a more reasonable log file size (256 KB instead of 10 MB). 
* Checkpoint on exit.
 2003-07-31 14:28:49 +00:00
Eelco Dolstra 4a013962bd * Started using Berkeley DB environments. This is necessary for 
transaction support (but we don't actually use transactions yet).
 2003-07-31 13:47:13 +00:00
Eelco Dolstra 758bd4673a * Set execute bit. 2003-07-31 13:13:27 +00:00
Eelco Dolstra 9f4c19276d * Basic makefile. 2003-07-31 13:13:13 +00:00
Eelco Dolstra 26ff1cdf89 * A better test case for Nix race conditions. 2003-07-30 14:40:46 +00:00
Eelco Dolstra 64c617e984 * Directories for the manual. 2003-07-30 14:40:18 +00:00
Eelco Dolstra 2ac02440dc * Test cases for races. 2003-07-30 13:35:46 +00:00
Eelco Dolstra aaee69cfde * INSTALL_DATA -> INSTALL_PROGRAM to ensure that the execute bit 
remains set.
 2003-07-30 10:14:58 +00:00
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
