2006-12-02 * Remove queryPathHash().Eelco Dolstra1-1/+4
* Help for nix-worker.
2006-12-01 * Replace read-only calls to addTextToStore.Eelco Dolstra1-2/+6
2006-12-01 * Merge addToStore and addToStoreFixed.Eelco Dolstra7-80/+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 Dolstra4-31/+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 Dolstra8-33/+63
* Added new operation hasSubstitutes(), which is more efficient than querySubstitutes().size() > 0.
2006-11-30 * Doh.Eelco Dolstra1-1/+1
2006-11-30 * More operations.Eelco Dolstra2-8/+23
2006-11-30 * First remote operation: isValidPath().Eelco Dolstra3-5/+32
2006-11-30 * When NIX_REMOTE is set to "slave", fork off nix-worker in slaveEelco Dolstra3-1/+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 Dolstra1-2/+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 Dolstra2-0/+135
2006-11-30 * Skeleton of remote store implementation.Eelco Dolstra3-5/+13
2006-11-30 * Put building in the store API.Eelco Dolstra7-37/+24
2006-11-30 * Refactoring. There is now an abstract interface class StoreAPIEelco Dolstra10-310/+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 Dolstra1-6/+2
(NIX-70)
2006-11-24 * Dead files.Eelco Dolstra2-12/+0
2006-11-13 * Remove the undocumented `noscan' feature. It's no longer necessaryEelco Dolstra1-15/+12
now that reference scanning is sufficiently streamy.
2006-11-13 * Magic attribute `exportReferencesGraph' that allows the referencesEelco Dolstra2-20/+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, ifEelco Dolstra2-1/+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 toEelco Dolstra1-0/+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, stringEelco Dolstra1-12/+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 Dolstra1-0/+2
2006-10-13 * Don't crash when upgrading the Berkeley DB environment.Eelco Dolstra1-1/+6
2006-09-22 * Use a bounded amount of memory in scanForReferences() by not readingEelco Dolstra1-9/+26
regular files into memory all at once.
2006-09-22 * Don't allocate the buffer twice.Eelco Dolstra1-7/+9
2006-09-22 * Don't allocate more than SIZE_MAX bytes.Eelco Dolstra1-0/+7
2006-09-14 * Fix a huge gaping hole in nix-env w.r.t. the garbage collector.Eelco Dolstra2-10/+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 Dolstra1-6/+8
2006-09-04 * Remove unnecessary inclusions of aterm2.h.Eelco Dolstra3-1/+5
2006-09-04 * Use a proper namespace.Eelco Dolstra18-82/+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 Dolstra1-1/+1
2006-08-15 On cygwin, disable the check that the output is not group or worldMartin Bravenboer1-0/+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 storeEelco Dolstra1-0/+9
objects that would be freed.
2006-08-11 * Don't assume that paths returned by the runtime root finder areEelco Dolstra1-1/+1
valid.
2006-08-01 * Show some progress.Eelco Dolstra1-0/+1
2006-07-20 * Use $(libexecdir) to find find-runtime-roots.pl.Eelco Dolstra3-1/+6
2006-07-20 * Use debug().Eelco Dolstra1-1/+1
2006-07-20 * Call find-runtime-roots.pl from the garbage collector to preventEelco Dolstra2-16/+36
running applications etc. from being garbage collected.
2006-07-06 * Allow the canonical system name to be specified at runtime in theEelco Dolstra2-1/+5
Nix config file.
2006-06-20 * Concurrent GC on Cygwin.Eelco Dolstra3-73/+146
2006-06-19 * Oops.Eelco Dolstra1-1/+2
2006-06-19 * _exit() doesn't seem to work right on Cygwin.Eelco Dolstra1-0/+11
2006-06-19 * On Windows we cannot delete open (lock) files, so we delete lockEelco Dolstra1-4/+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 Dolstra1-4/+4
2006-06-15 * In `nix-env -i|-u|-e', lock the profile to prevent races betweenEelco Dolstra2-6/+11
concurrent nix-env operations on the same profile. Fixes NIX-7.
2006-06-01 * Minor cleanup.Eelco Dolstra1-7/+3
2006-05-31 * For fixed-output derivations, pass the environment variables listedEelco Dolstra1-3/+20
in the attribute variable `impureEnvVars' from the caller to the builder.
2006-05-30 * Not all platforms have sys/select.h.Eelco Dolstra1-1/+1
2006-05-29 * Disable the concurrent garbage collector on Cygwin for now.Eelco Dolstra1-0/+8
2006-05-24 * Some Cygwin fixes.Eelco Dolstra1-0/+1
