2006-12-03	* Use a Unix domain socket instead of pipes.	Eelco Dolstra	2	-15/+18

2006-12-03	* Better error message if the worker doesn't start.	Eelco Dolstra	1	-4/+8

2006-12-03	* Some hackery to propagate the worker's stderr and exceptions to the	Eelco Dolstra	4	-8/+44
	client.
2006-12-02	* Move addTempRoot() to the store API, and add another function	Eelco Dolstra	8	-13/+64
	syncWithGC() to allow clients to register GC roots without needing write access to the global roots directory or the GC lock.
2006-12-02	* Remove SwitchToOriginalUser, we're not going to need it anymore.	Eelco Dolstra	3	-20/+4

2006-12-02	* Remove queryPathHash().	Eelco Dolstra	1	-1/+4
	* Help for nix-worker.
2006-12-01	* Replace read-only calls to addTextToStore.	Eelco Dolstra	1	-2/+6

2006-12-01	* Merge addToStore and addToStoreFixed.	Eelco Dolstra	7	-80/+30
	* addToStore now adds unconditionally, it doesn't use readOnlyMode. Read-only operation is up to the caller (who can call computeStorePathForPath).
2006-12-01	* More operations.	Eelco Dolstra	4	-31/+95
	* addToStore() and friends: don't do a round-trip to the worker if we're only interested in the path (i.e., in read-only mode).
2006-11-30	* More remote operations.	Eelco Dolstra	8	-33/+63
	* Added new operation hasSubstitutes(), which is more efficient than querySubstitutes().size() > 0.
2006-11-30	* Doh.	Eelco Dolstra	1	-1/+1

2006-11-30	* More operations.	Eelco Dolstra	2	-8/+23

2006-11-30	* First remote operation: isValidPath().	Eelco Dolstra	3	-5/+32

2006-11-30	* When NIX_REMOTE is set to "slave", fork off nix-worker in slave	Eelco Dolstra	3	-1/+65
	mode. Presumably nix-worker would be setuid to the Nix store user. The worker performs all operations on the Nix store and database, so the caller can be completely unprivileged. This is already much more secure than the old setuid scheme, since the worker doesn't need to do Nix expression evaluation and so on. Most importantly, this means that it doesn't need to access any user files, with all resulting security risks; it only performs pure store operations. Once this works, it is easy to move to a daemon model that forks off a worker for connections established through a Unix domain socket. That would be even more secure.
2006-11-30	* Skeleton of the privileged worker program.	Eelco Dolstra	1	-2/+2
	* Some refactoring: put the NAR archive integer/string serialisation code in a separate file so it can be reused by the worker protocol implementation.
2006-11-30	* Oops.	Eelco Dolstra	2	-0/+135

2006-11-30	* Skeleton of remote store implementation.	Eelco Dolstra	3	-5/+13

2006-11-30	* Put building in the store API.	Eelco Dolstra	7	-37/+24

2006-11-30	* Refactoring. There is now an abstract interface class StoreAPI	Eelco Dolstra	10	-310/+428
	containing functions that operate on the Nix store. One implementation is LocalStore, which operates on the Nix store directly. The next step, to enable secure multi-user Nix, is to create a different implementation RemoteStore that talks to a privileged daemon process that uses LocalStore to perform the actual operations.
2006-11-24	* Doh! Path sizes need to be computed recursively of course.	Eelco Dolstra	1	-6/+2
	(NIX-70)
2006-11-24	* Dead files.	Eelco Dolstra	2	-12/+0

2006-11-13	* Remove the undocumented `noscan' feature. It's no longer necessary	Eelco Dolstra	1	-15/+12
	now that reference scanning is sufficiently streamy.
2006-11-13	* Magic attribute `exportReferencesGraph' that allows the references	Eelco Dolstra	2	-20/+60
	graph to be passed to a builder. This attribute should be a list of pairs [name1 path1 name2 path2 ...]. The references graph of each `pathN' will be stored in a text file `nameN' in the temporary build directory. The text files have the format used by `nix-store --register-validity'. However, the deriver fields are left empty. `exportReferencesGraph' is useful for builders that want to do something with the closure of a store path. Examples: the builders that make initrds and ISO images for NixOS. `exportReferencesGraph' is entirely pure. It's necessary because otherwise the only way for a builder to get this information would be to call `nix-store' directly, which is not allowed (though unfortunately possible).
2006-10-28	* `nix-store --read-log / -l PATH' shows the build log of PATH, if	Eelco Dolstra	2	-1/+4
	available. For instance, $ nix-store -l $(which svn) \| less lets you read the build log of the Subversion instance in your profile. * `nix-store -qb': if applied to a non-derivation, take the deriver.
2006-10-19	* Special derivation attribute `allowedReferences' that causes Nix to	Eelco Dolstra	1	-0/+31
	check that the references of the output of a derivation are in the specified set. For instance, allowedReferences = []; specifies that the output cannot have any references. (This is useful, for instance, for the generation of bootstrap binaries for stdenv-linux, which must not have any references for purity). It could also be used to guard against undesired runtime dependencies, e.g., {gcc, dynlib}: derivation { ... allowedReferences = [dynlib]; } says that the output can refer to the path of `dynlib' but not `gcc'. A `forbiddedReferences' attribute would be more useful for this, though.
2006-10-16	* Big cleanup of the semantics of paths, strings, contexts, string	Eelco Dolstra	1	-12/+2
	concatenation and string coercion. This was a big mess (see e.g. NIX-67). Contexts are now folded into strings, so that they don't cause evaluation errors when they're not expected. The semantics of paths has been clarified (see nixexpr-ast.def). toString() and coerceToString() have been merged. Semantic change: paths are now copied to the store when they're in a concatenation (and in most other situations - that's the formalisation of the meaning of a path). So "foo " + ./bla evaluates to "foo /nix/store/hash...-bla", not "foo /path/to/current-dir/bla". This prevents accidental impurities, and is more consistent with the treatment of derivation outputs, e.g., `"foo " + bla' where `bla' is a derivation. (Here `bla' would be replaced by the output path of `bla'.)
2006-10-13	* A helpful message.	Eelco Dolstra	1	-0/+2

2006-10-13	* Don't crash when upgrading the Berkeley DB environment.	Eelco Dolstra	1	-1/+6

2006-09-22	* Use a bounded amount of memory in scanForReferences() by not reading	Eelco Dolstra	1	-9/+26
	regular files into memory all at once.
2006-09-22	* Don't allocate the buffer twice.	Eelco Dolstra	1	-7/+9

2006-09-22	* Don't allocate more than SIZE_MAX bytes.	Eelco Dolstra	1	-0/+7

2006-09-14	* Fix a huge gaping hole in nix-env w.r.t. the garbage collector.	Eelco Dolstra	2	-10/+15
	Nix-env failed to call addPermRoot(), which is necessary to safely add a new root. So if nix-env started after and finished before the garbage collector, the user environment (plus all other new stuff) it built might be garbage collected, leading to a dangling symlink chain in ~/.nix-profile... * Be more explicit if we block on the GC lock ("waiting for the big garbage collector lock..."). * Don't loop trying to create a new generation. It's not necessary anymore since profiles are locked nowadays.
2006-09-04	* Install header files in /nix/include/nix.	Eelco Dolstra	1	-6/+8

2006-09-04	* Remove unnecessary inclusions of aterm2.h.	Eelco Dolstra	3	-1/+5

2006-09-04	* Use a proper namespace.	Eelco Dolstra	18	-82/+193
	* Optimise header file usage a bit. * Compile the parser as C++.
2006-09-04	* Store the Nix libraries in ${libdir}/nix instead of ${libdir}.	Eelco Dolstra	1	-1/+1

2006-08-15	On cygwin, disable the check that the output is not group or world	Martin Bravenboer	1	-0/+2
	writable. File permissions on Cygwin are rather complex, and in this case this check introduced a problem with build jobs invoke from outside of Cygwin (MSYS). It seemed almost impossible to fix the permissions of the directory, so for now this safety check is disabled on Cygwin.
2006-08-11	* `nix-store --gc --print-dead': print the total size of the store	Eelco Dolstra	1	-0/+9
	objects that would be freed.
2006-08-11	* Don't assume that paths returned by the runtime root finder are	Eelco Dolstra	1	-1/+1
	valid.
2006-08-01	* Show some progress.	Eelco Dolstra	1	-0/+1

2006-07-20	* Use $(libexecdir) to find find-runtime-roots.pl.	Eelco Dolstra	3	-1/+6

2006-07-20	* Use debug().	Eelco Dolstra	1	-1/+1

2006-07-20	* Call find-runtime-roots.pl from the garbage collector to prevent	Eelco Dolstra	2	-16/+36
	running applications etc. from being garbage collected.
2006-07-06	* Allow the canonical system name to be specified at runtime in the	Eelco Dolstra	2	-1/+5
	Nix config file.
2006-06-20	* Concurrent GC on Cygwin.	Eelco Dolstra	3	-73/+146

2006-06-19	* Oops.	Eelco Dolstra	1	-1/+2

2006-06-19	* _exit() doesn't seem to work right on Cygwin.	Eelco Dolstra	1	-0/+11

2006-06-19	* On Windows we cannot delete open (lock) files, so we delete lock	Eelco Dolstra	1	-4/+47
	files after we've closed them. Since this only succeeds if the lock is no longer opened by any process, the token trick used on Unix is not necessary.
2006-06-16	* Show when we're blocked waiting for a lock.	Eelco Dolstra	1	-4/+4

2006-06-15	* In `nix-env -i\|-u\|-e', lock the profile to prevent races between	Eelco Dolstra	2	-6/+11
	concurrent nix-env operations on the same profile. Fixes NIX-7.
