2005-03-21	* Remove non-POSIX flag.	Eelco Dolstra	1	-1/+1

2005-03-10	* Check for duplicate attributes and formal parameters in Nix	Eelco Dolstra	5	-0/+31
	expressions.
2005-02-18	* `make check' fix.	Eelco Dolstra	1	-1/+1

2005-02-15	* Fix broken GC test.	Eelco Dolstra	2	-1/+9

2005-02-09	* Propagate the deriver of a path through the substitute mechanism.	Eelco Dolstra	11	-42/+50
	* Removed some dead code (successor stuff) from nix-push. * Updated terminology in the tests (store expr -> drv path). * Check that the deriver is set properly in the tests.
2005-02-01	* Make check fixes.	Eelco Dolstra	4	-12/+10

2005-02-01	* Add missing files to dist.	Eelco Dolstra	2	-2/+6
	* Fix GC and substitute bugs related to self-references. Add a regression test.
2005-01-31	* Acquire a global GC lock to prevent new temporary root files from	Eelco Dolstra	2	-4/+7
	being created after the garbage collector has read the temproots directory. This blocks the creation of new processes, but the garbage collector could periodically release the GC lock to allow them to run.
2005-01-31	* Add a test for a more subtle race: a process starting after the	Eelco Dolstra	4	-18/+65
	temporary root files have been read but creating outputs before the store directory has been read.
2005-01-31	* Don't delete active lock files.	Eelco Dolstra	2	-5/+8

2005-01-31	* Start of concurrent garbage collection. Processes write temporary	Eelco Dolstra	3	-4/+8
	roots to a per-process temporary file in /nix/var/nix/temproots while holding a write lock on that file. The garbage collector acquires read locks on all those files, thus blocking further progress in other Nix processes, and reads the sets of temporary roots.
2005-01-28	* Add a test to check whether concurrent garbage collection (i.e.,	Eelco Dolstra	4	-1/+56
	running the collector while builds are in progress) works correctly. The test currently fails.
2005-01-28	* Another horrible `make check' hack.	Eelco Dolstra	1	-2/+3

2005-01-27	* Set execute permission.	Eelco Dolstra	1	-1/+3

2005-01-27	* Add missing substitutes files to dist.	Eelco Dolstra	4	-20/+25
	* Add a garbage collector test.
2005-01-27	* Remove deleted files from EXTRA_DIST (again).	Eelco Dolstra	1	-3/+1

2005-01-25	* Remove removed files from EXTRA_DIST.	Eelco Dolstra	1	-2/+2

2005-01-25	* Re-enable all tests.	Eelco Dolstra	4	-8/+6

2005-01-25	* Really fix the substitute mechanism, i.e., ensure the closure	Eelco Dolstra	4	-2/+88
	invariant by registering references through the manifest. * Added a test for nix-pull.
2005-01-25	* Fix the `--fallback' switch.	Eelco Dolstra	9	-86/+28
	* Fix the substitutes tests.
2005-01-25	* Fix the build hook mechanism; pass the pointer graph to the hook.	Eelco Dolstra	2	-3/+3

2005-01-25	* In nix-store: added query `--referers-closure' that returns the	Eelco Dolstra	1	-1/+4
	closure of the referers relation rather than the references relation, i.e., the set of all paths that directly or indirectly refer to the given path. Note that contrary to the references closure this set is not fixed; it can change as paths are added to or removed from the store.
2005-01-25	* In nix-store: change `--build' back to `--realise'. Also brought	Eelco Dolstra	4	-7/+7
	back the query flag `--force-realise'. * Fixed some of the tests.
2005-01-19	* Change extension `.store' to `.drv'.	Eelco Dolstra	2	-2/+2
	* Re-enable `nix-store --query --requisites'.
2005-01-14	* Missing file.	Eelco Dolstra	1	-0/+50

2005-01-14	* Add SHA-256.	Eelco Dolstra	1	-1/+1
	* Tests for the various hashes.
2005-01-04	* Cygwin compatibility.	Eelco Dolstra	1	-2/+2

2004-12-20	* I love test sets.	Eelco Dolstra	3	-18/+21

2004-10-27	* Use `atdiff' instead of `cmp' for checking test output.	Eelco Dolstra	4	-5/+6
	* Don't use local file names in tests since they will produce different parse trees depending on the current directory.
2004-10-27	* Bug fix in parsing of /* ... */ comments; due to longest match	Eelco Dolstra	3	-1/+13
	regexp there could be only one such comment per file.
2004-10-27	* Remove ancient Fix tests.	Eelco Dolstra	22	-3/+145
	* Add automated Nix expression language tests.
2004-08-19	* Make sure that no build hook is set by default in the tests.	Eelco Dolstra	2	-1/+2
	* Don't use `seq' - some primitive, obsolete operating systems (Darwin) don't have it.
2004-06-28	* Typo.	Eelco Dolstra	1	-1/+1

2004-06-28	* Added a switch `--fallback'. From the manual:	Eelco Dolstra	4	-4/+5
	Whenever Nix attempts to realise a derivation for which a closure is already known, but this closure cannot be realised, fall back on normalising the derivation. The most common scenario in which this is useful is when we have registered substitutes in order to perform binary distribution from, say, a network repository. If the repository is down, the realisation of the derivation will fail. When this option is specified, Nix will build the derivation instead. Thus, binary installation falls back on a source installation. This option is not the default since it is generally not desirable for a transient failure in obtaining the substitutes to lead to a full build from source (with the related consumption of resources).
2004-06-25	* A flag `--keep-going / -k' to keep building goals if one fails, as	Eelco Dolstra	2	-5/+5
	much as possible. (This is similar to GNU Make's `-k' flag.) * Refactoring to implement this: previously we just bombed out when a build failed, but now we have to clean up. In particular this means that goals must be freed quickly --- they shouldn't hang around until the worker exits. So the worker now maintains weak pointers in order not to prevent garbage collection. * Documented the `-k' and `-j' flags.
2004-06-24	* Add a test to check that when we cannot realise a closure	Eelco Dolstra	3	-3/+26
	expression, we should invalidate it and go back to the derivation for which it is a successor.
2004-06-24	* Multiple and/or failing substitutes now work.	Eelco Dolstra	3	-7/+12

2004-06-24	* A test for multiple and/or failing substitutes.	Eelco Dolstra	5	-5/+80

2004-06-21	* Missing files added to `make dist'.	Eelco Dolstra	1	-1/+2

2004-06-20	* Re-enable support for substitutes in the normaliser.	Eelco Dolstra	5	-1/+61
	* A better substitute mechanism. Instead of generating a store expression for each store path for which we have a substitute, we can have a single store expression that builds a generic program that is invoked to build the desired store path, which is passed as an argument. This means that operations like `nix-pull' only produce O(1) files instead of O(N) files in the store when registering N substitutes. (It consumes O(N) database storage, of course, but that's not a performance problem). * Added a test for the substitute mechanism. * `nix-store --substitute' reads the substitutes from standard input, instead of from the command line. This prevents us from running into the kernel's limit on command line length.
2004-06-19	* Re-enable build hooks.	Eelco Dolstra	1	-3/+2

2004-06-18	* Big refactoring. Move to a much more explicitly state machine based	Eelco Dolstra	2	-2/+5
	approach. This makes it much easier to add extra complexity in the normaliser / realiser (e.g., build hooks, substitutes).
2004-05-13	* Set the executable bit.	Eelco Dolstra	1	-0/+0

2004-05-13	* Perform all tests.	Eelco Dolstra	1	-4/+2

2004-05-13	* The build hooks used to implement distributed builds can now be run	Eelco Dolstra	4	-10/+16
	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. The implementation is a bit messy right now, though. * The directory `distributed' shows a (hacky) example of a hook that distributes build jobs over a set of machines listed in a configuration file.
2004-05-12	* Use `-j0'.	Eelco Dolstra	1	-8/+1

2004-05-12	* A switch `-j NUMBER' to set the maximum number of parallel jobs (0 =	Eelco Dolstra	1	-1/+1
	no limit). * Add missing file to distribution.
2004-05-12	* Broken test.	Eelco Dolstra	1	-3/+3

2004-05-12	* An quick and dirty hack to support distributed builds.	Eelco Dolstra	4	-2/+59

2004-05-11	* True parallel builds. Nix can now run as many build jobs in	Eelco Dolstra	4	-14/+13
	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. TODO: substitutes are currently broken.
