2004-06-28 10:42:57 +0000
b113edeab7* A flag --keep-going / -k' to keep building goals if one fails, as much as possible. (This is similar to GNU Make's -k' flag.)
Eelco Dolstra
2004-06-25 15:36:09 +0000
e4883211f9* Don't throw an exception when a build fails. Just terminate the goal and allow the problem to be handled elsewhere (e.g., at top-level).
Eelco Dolstra
2004-06-25 10:21:44 +0000
a29c8ac51c* Add a test to check that when we cannot realise a closure expression, we should invalidate it and go back to the derivation for which it is a successor.
Eelco Dolstra
2004-06-24 14:35:01 +0000
05a5362d63* Some more diagnostics changes.
Eelco Dolstra
2004-06-22 17:04:10 +0000
d051cd40e1* Nix-instantiate can return multiple store expressions.
Eelco Dolstra
2004-06-22 15:17:04 +0000
3093af58a7* A utility script `nix-build' that builds Nix expressions and prints their output paths (and only that) on standard output.
Eelco Dolstra
2004-06-22 15:12:34 +0000
b302e5f63b* We don't really need this here.
Eelco Dolstra
2004-06-22 15:06:43 +0000
37ee6cef99* Adapted nix-pull to use the new substitute mechanism.
Eelco Dolstra
2004-06-21 09:51:23 +0000
3f3a3ae87b* Acquire a lock on the output path when running a substitute. Also delete obstructing invalid paths.
Eelco Dolstra
2004-06-21 09:35:50 +0000
72c857f0eb* Ugh, nasty Heisenbug due to an uninitialiased variable. The bug only caused a crash if the program was *not* invoked with a high verbosity level.
Eelco Dolstra
2004-06-21 08:51:55 +0000
daf0a923c7* Wrap calls to registerSubstitute() in a single transaction to improve throughput. * Don't build the `substitute-rev' table for now, since it caused Theta(N^2) time and log file consumption when adding N substitutes. Maybe we can do without it.
Eelco Dolstra
2004-06-21 07:38:17 +0000
15c60ca1b6* Disable calls to fsync() since Berkeley DB's DB_TXN_WRITE_NOSYNC flag doesn't seem to work as advertised.
Eelco Dolstra
2004-06-21 07:36:01 +0000
112ee89501* Re-enable support for substitutes in the normaliser.
Eelco Dolstra
2004-06-20 19:17:54 +0000
bafb2357d1* README for the Emacs mode (written a while ago, but forgot to commit).
Eelco Dolstra
2004-06-20 19:08:59 +0000
41ec982f31* Big refactoring. Move to a much more explicitly state machine based approach. This makes it much easier to add extra complexity in the normaliser / realiser (e.g., build hooks, substitutes).
Eelco Dolstra
2004-06-18 18:09:32 +0000
3454c685ee* This is also useful.
Eelco Dolstra
2004-06-18 16:52:31 +0000
e8411948ff* A Nix mode for Emacs.
Eelco Dolstra
2004-06-04 14:31:57 +0000
5e4a2272bf* Drain the output of the build hook to show error messages. Ugly hack.
Eelco Dolstra
2004-05-18 14:52:35 +0000
19479899fb* Don't set the rpath here --- it's not portable.
Eelco Dolstra
2004-05-18 12:57:26 +0000
1d08093b48* Go back to the old way of generating the system name, and allow it to be specified in configure (using `--with-system=SYSTEM').
Eelco Dolstra
2004-05-18 09:45:46 +0000
8e9fd57ef9* setpgrp() is not POSIX (and on Mac OS X it's different than on Linux), so use setpgid().
Eelco Dolstra
2004-05-18 09:45:18 +0000
ace8872706* execl() requires a terminating 0. * When a fast build wakes up a goal, try to start that goal in the same iteration of the startBuild() loop of run(). Otherwise no job might be started until the next job terminates.
Eelco Dolstra
2004-05-14 12:24:29 +0000
4fc00cbec1* Distributed builds and load balancing now seem to work pretty well. (Though the `build-remote.pl' script has a gigantic race condition).
Eelco Dolstra
2004-05-13 22:52:37 +0000
2fa3304933* Set the executable bit.
Eelco Dolstra
2004-05-13 20:28:20 +0000
25db622454* Load balancing. `build-remote.pl' will only execute up to a per-machine maximum number of parallel jobs on a remote machine.
Eelco Dolstra
2004-05-13 19:35:46 +0000
3426d19547* Perform all tests.
Eelco Dolstra
2004-05-13 19:16:48 +0000
a8306cb98f* The build hooks used to implement distributed builds can now be run in parallel. Hooks are more efficient: locks on output paths are only acquired when the hook says that it is willing to accept a build job. Hooks now work in two phases. First, they should first tell Nix whether they are willing to accept a job. Nix guarantuees that no two hooks will ever be in the first phase at the same time (this simplifies the implementation of hooks, since they don't have to perform locking (?)). Second, if they accept a job, they are then responsible for building it (on the remote system), and copying the result back. These can be run in parallel with other hooks and locally executed jobs.
Eelco Dolstra
2004-05-13 19:14:49 +0000
5087c8f645* Use `-j0'.
Eelco Dolstra
2004-05-12 14:30:57 +0000
efa5fa1a91* A switch `-j NUMBER' to set the maximum number of parallel jobs (0 = no limit). * Add missing file to distribution.
Eelco Dolstra
2004-05-12 14:20:32 +0000
aa5a5084e4* Pass to the build hook all sorts of information useful for distributing a build action to another machine. In particular, the paths in the input closures, the output paths, and successor mapping for sub-derivations.
Eelco Dolstra
2004-05-12 13:32:26 +0000
8c0b42f857* An quick and dirty hack to support distributed builds.
Eelco Dolstra
2004-05-12 09:35:51 +0000
c8d3882cdc* True parallel builds. Nix can now run as many build jobs in parallel as possible (similar to GNU Make's `-j' switch). This is useful on SMP systems, but it is especially useful for doing builds on multiple machines. The idea is that a large derivation is initiated on one master machine, which then distributes sub-derivations to any number of slave machines. This should not happen synchronously or in lock-step, so the master must be capable of dealing with multiple parallel build jobs. We now have the infrastructure to support this.

2004-05-11 18:05:44 +0000
aea436503e* Ignore interrupt signals while handling an exception. * Ignore EINTR in reads and writes.
Eelco Dolstra
2004-05-11 13:48:25 +0000
a9858c9f26* A test to verify that Nix executes build jobs in parallel, if possible.
Eelco Dolstra
2004-05-04 17:04:17 +0000
f044ccf702* 1000th revision! * A test to verify that locking of output paths (caused by concurrent invocations of Nix) works correctly.
Eelco Dolstra
2004-05-04 13:56:30 +0000
a7bbe73971* Another test.
Eelco Dolstra
2004-05-04 13:22:33 +0000
ef093aac8f* Grrr. TESTS are not included in EXTRA_DIST.
Eelco Dolstra
2004-05-04 12:45:04 +0000
256eeab711* Allow the location of the store etc. to be specified using environment variables. * Started adding some automatic tests. * Do a `make check' when building RPMs.

2004-05-04 12:15:30 +0000
fd927c5d25* Bump the version number.
Eelco Dolstra
2004-04-26 13:44:26 +0000
21655a70f5* Channels. These allow you to stay current with an evolving set of Nix expressions.
Eelco Dolstra
2004-04-21 14:54:05 +0000
f79e9c2d22* Do initialise state (the DB etc.) when doing a make install', unless --disable-init-state' is passed to configure.
Eelco Dolstra
2004-04-21 10:54:46 +0000
8e459d919d* Recurse into attribute sets and lists when getting derivations from an expression.
Eelco Dolstra
2004-04-21 09:37:37 +0000
7cce0c34e1* Allow extra parameters to be passed to Curl through the CURL_FLAGS' environment variable. This is useful for passing authentication information (it won't show up in ps'). Hacky - nix-push should abstract over the use of Curl.
Eelco Dolstra
2004-04-15 15:14:16 +0000
2c5a8bf49f* Use @storedir@, not @prefix@/store.

2004-04-06 15:55:27 +0000
2be8ac48bb* Make the creation of user environments much faster and more storage efficient by creating only a single symlink to entire directory trees unless a collission occurs.
Eelco Dolstra
2004-04-06 11:42:28 +0000
bf3863b546* Fail if prerequisites are missing.
Eelco Dolstra
2004-04-06 08:40:19 +0000
03f1d1ecb5* Switched from wget to curl. * Made the dependencies on bzip2 and the shell explicit.

2004-04-06 08:18:51 +0000
59b94ee18a* When something goes wrong in the evaluation of a Nix expression, print a nice backtrace of the stack, rather than vomiting a gigantic (and useless) aterm on the screen. Example:

2004-04-05 22:27:41 +0000
a520b1cbc3* Print a more useful error message in case of an invalid derivation binding.
Eelco Dolstra
2004-04-02 10:49:37 +0000
c4ac2a164a* The recent change in nixpkgs of calling stdenv.mkDerivation' instead of derivation' triggered a huge slowdown in the Nix expression evaluator. Total execution time of `nix-env -qa' went up by a factor of 60 or so.
Eelco Dolstra
2004-03-30 15:05:35 +0000
df101d6fca* Specify Perl as a dependency for the RPM.
Eelco Dolstra
2004-03-29 12:10:15 +0000
ac4d39f9db* Added an operator ?' to test for attribute existence, e.g., attrs ? x' yields true iff attrs' has an attribute named x'.
Eelco Dolstra
2004-03-28 21:15:01 +0000
f958bcdf1f* Added an operator `~' to select paths within a derivation. E.g.,
Eelco Dolstra
2004-03-28 20:58:28 +0000
db3e644c1c* Added plain lambdas, e.g., let { id = x: x; const = x: y: x; }'. bla:' is now no longer parsed as a URL.
Eelco Dolstra
2004-03-28 20:34:22 +0000
f8cd904e05* Disallow the Nix store or any of its parents from being symlinks. This is because the contents of these symlinks are not incorporated into the hashes of derivations, and could therefore cause a mismatch between the build system and the target system. E.g., if /nix/store' is a symlink to /data/nix/store', then a builder could expand this path and store the result. If on the target system `/nix/store' is not a symlink, or is a symlink that points somewhere else, we have a dangling pointer.

2004-03-27 17:58:04 +0000
f0f7a9f299* Do not close a nesting level twice after close() has been called explicitly on a Nest object.
Eelco Dolstra
2004-03-27 15:33:19 +0000
7823db2137* Some more nesting.

e6253b58cd* Escape codes to force line breaks to be ignored.
Eelco Dolstra
2004-03-18 21:32:15 +0000
3f3c4cce5a* Added an extra escape code to signal "unimportant" messages. If a tree only has unimportant messages, it is collapsed by the default. * Also added an optional integer argument to the escape code for opening a nesting level to indicate lack of importance. If set, the tree is collapsed by default.
Eelco Dolstra
2004-03-18 21:04:14 +0000
c2fc2c13c9* Use unordered lists, which is more sensible semantically for representing tree structures.
