2007-08-06	* Optionally warn about packages that give an assertion failure.	Eelco Dolstra	1	-1/+1

2007-07-05	* Properly keep packages during upgrades.	Eelco Dolstra	1	-1/+4

2007-06-12	* Support queryDeriver() in multi-user installations.	Eelco Dolstra	10	-16/+42

2007-06-11	* Check against creation of GC roots in the store. Those roots don't	Eelco Dolstra	1	-1/+5
	work, because findRoots() stops when it encounters a symlink to the store. And of course the store is supposed to be read-only.
2007-05-16	* New builtin function "isFunction". You're not supposed to use it	Eelco Dolstra	2	-1/+14
	;-) * Channels: fix channels that are plain lists of derivations (like strategoxt-unstable) instead of functions (like nixpkgs-unstable). This fixes the error message "error: the left-hand side of the function call is neither a function nor a primop (built-in operation) but a list".
2007-05-15	* Allow empty argument lists in function definitions (e.g., `{}:	Eelco Dolstra	1	-0/+1
	bla'). Also allow trailing commas (`{x, y,}: ...') as a unintented consequence. Hopefully the reduce/reduce conflict won't cause any problems.
2007-05-14	* Typo (reported by Marc Weber).	Eelco Dolstra	1	-1/+1

2007-05-07	* Create the database directory if it doesn't exist.	Eelco Dolstra	1	-0/+9

2007-05-01	* Give unpacked channels more sensible names than 0, 1, ... They now	Eelco Dolstra	1	-3/+12
	get the basename of the channel URL (e.g., nixpkgs-unstable). The top-level Nix expression of the channel is now an attribute set, the attributes of which are the individual channels (e.g., {nixpkgs_unstable = ...; strategoxt_unstable = ...}). This makes attribute paths ("nix-env -qaA" and "nix-env -iA") more sensible, e.g., "nix-env -iA nixpkgs_unstable.subversion".
2007-05-01	* nix-env -i: instead of breaking package ties by version, break them	Eelco Dolstra	3	-13/+48
	by priority and version install. That is, if there are multiple packages with the same name, then pick the package with the highest priority, and only use the version if there are multiple packages with the same priority. This makes it possible to mark specific versions/variant in Nixpkgs more or less desirable than others. A typical example would be a beta version of some package (e.g., "gcc-4.2.0rc1") which should not be installed even though it is the highest version, except when it is explicitly selected (e.g., "nix-env -i gcc-4.2.0rc1"). * Idem for nix-env -u, only the semantics are a bit trickier since we also need to take into account the priority of the currently installed package (we never upgrade to a lower priority, unless --always is given).
2007-05-01	* Set a terminate() handler to ensure that we leave the BDB	Eelco Dolstra	6	-8/+55
	environment cleanly even when an exception is thrown from a destructor. We still crash, but we don't take all other Nix processes with us.
2007-05-01	* Make --verify more interruptable.	Eelco Dolstra	1	-0/+1

2007-05-01	* `nix-env -q --xml --meta' to show all meta attributes.	Eelco Dolstra	2	-1/+17

2007-04-30	* Doh.	Eelco Dolstra	1	-1/+1

2007-04-27	* Package flag "keep" that prevents a package from being removed from	Eelco Dolstra	1	-1/+6
	a user environment by an install or upgrade action. This is particularly useful if you have a version installed that you don't want to upgrade (e.g., because the newer versions are broken). Example: $ nix-env -u zapping --dry-run (dry run; not doing anything) upgrading `zapping-0.9.6' to `zapping-0.10cvs6' $ nix-env --set-flag keep true zapping $ nix-env -u zapping --dry-run (dry run; not doing anything) However, "-e" will still uninstall the package. (Maybe we should require the keep flag to be explicitly set to false before it can be uninstalled.)
2007-04-26	* nix-env -q now has a flag --prebuilt-only (-b<) that causes nix-env	Eelco Dolstra	2	-6/+16
	to show only those derivations whose output is already in the Nix store or that can be substituted (i.e., downloaded from somewhere). In other words, it shows the packages that can be installed “quickly”, i.e., don’t need to be built from source.
2007-04-16	* New primop "throw <string>" to throw an error. This is like abort,	Eelco Dolstra	3	-0/+13
	only thrown errors are caught by the top-level derivation evaluation in nix-env -qa / -i.
2007-04-16	* Remove a warning.	Eelco Dolstra	1	-1/+1

2007-03-30	* Work around a bug in Apple's GCC preprocessor.	Eelco Dolstra	3	-4/+5

2007-03-28	* Handle ECONNRESET from the client. Also, don't abort() if there are	Eelco Dolstra	1	-4/+9
	unexpected conditions in the SIGPOLL handler, since that messes up the Berkeley DB environment (which a client must never be able to trigger).
2007-03-20	* Override the setuid helper using NIX_SETUID_HELPER.	Eelco Dolstra	1	-1/+2

2007-03-19	* Terminate build hooks and substitutes with a TERM signal, not a KILL	Eelco Dolstra	3	-10/+27
	signal. This is necessary because those processes may have joined the BDB environment, so they have to be given a chance to clean up. (NIX-85)
2007-03-19	* Undocumented option `gc-check-reachability' to allow reachability	Eelco Dolstra	1	-7/+9
	checking to be turned off on machines with way too many roots.
2007-03-07	* Delete the output paths before invoking the build hook.	Eelco Dolstra	1	-14/+14

2007-03-01	* Look for the openssl program at compile time. If not found, call	Eelco Dolstra	1	-2/+2
	openssl through $PATH at runtime.
2007-03-01	* Don't check the signature unless we have to.	Eelco Dolstra	1	-21/+23

2007-02-27	* Doh! The deriver can be empty.	Eelco Dolstra	1	-1/+2

2007-02-27	* Greatly reduced the amount of stack space used by the Nix expression	Eelco Dolstra	1	-188/+274
	evaluator. This was important because the NixOS expressions started to hit 2 MB default stack size on Linux. GCC is really dumb about stack space: it just adds up all the local variables and temporaries of every scope into one huge stack frame. This is really bad for deeply recursive functions. For instance, every `throw Error(format("error message"))' causes a format object of a few hundred bytes to be allocated on the stack. As a result, every recursive call to evalExpr2() consumed 4680 bytes. By splitting evalExpr2() and by moving the exception-throwing code out of the main functions, evalExpr2() now only consumes 40 bytes. Similar for evalExpr().
2007-02-27	* When NIX_SHOW_STATS=1, show the amount of stack space consumed by	Eelco Dolstra	1	-2/+10
	the Nix expression evaluator.
2007-02-22	* Handle EINTR in select().	Eelco Dolstra	1	-3/+3

2007-02-21	* Flush cout to show progress.	Eelco Dolstra	1	-1/+1

2007-02-21	* Export/import many paths in one go.	Eelco Dolstra	1	-3/+8

2007-02-21	* `nix-store -qR' and friends: print the paths sorted topologically	Eelco Dolstra	3	-40/+12
	under the references relation. This is useful for commands that want to copy paths to another Nix store in the right order.
2007-02-21	* Flag `--print-invalid' in `nix-store --check-validity' to print out	Eelco Dolstra	1	-3/+14
	which paths specified on the command line are invalid (i.e., don't barf when encountering an invalid path, just print it). This is useful for build-remote.pl to figure out which paths need to be copied to a remote machine. (Currently we use rsync, but that's rather inefficient.)
2007-02-21	* Check that the file containing the secret key is secret.	Eelco Dolstra	1	-1/+14

2007-02-21	* `nix-store --import' now also works in remote mode. The worker	Eelco Dolstra	4	-9/+62
	always requires a signature on the archive. This is to ensure that unprivileged users cannot add Trojan horses to the Nix store.
2007-02-21	* Support exportPath() in remote mode.	Eelco Dolstra	4	-5/+42

2007-02-21	* importPath(): set the deriver.	Eelco Dolstra	1	-3/+13
	* exportPath(): lock the path, use a transaction.
2007-02-21	* `nix-store --import': import an archive created by `nix-store	Eelco Dolstra	8	-10/+142
	--export' into the Nix store, and optionally check the cryptographic signatures against /nix/etc/nix/signing-key.pub. (TODO: verify against a set of public keys.)
2007-02-21	* `nix-store --export --sign': sign the Nix archive using the RSA key	Eelco Dolstra	7	-29/+122
	in /nix/etc/nix/signing-key.sec
2007-02-20	* Start of `nix-store --export' operation for serialising a store	Eelco Dolstra	6	-0/+50
	path. This is like `nix-store --dump', only it also dumps the meta-information of the store path (references, deriver). Will add a `--sign' flag later to add a cryptographic signature, which we will use for exchanging store paths between build farm machines in a secure manner.
2007-02-06	* Fix 64-bit compiler warnings.	Eelco Dolstra	2	-4/+4

2007-02-02	* nix-env now maintains meta info (from the `meta' derivation	Eelco Dolstra	5	-16/+89
	attribute) about installed packages in user environments. Thus, an operation like `nix-env -q --description' shows useful information not only on available packages but also on installed packages. * nix-env now passes the entire manifest as an argument to the Nix expression of the user environment builder (not just a list of paths), so that in particular the user environment builder has access to the meta attributes. * New operation `--set-flag' in nix-env to change meta info of installed packages. This will be useful to pass per-package policies to the user environment builder (e.g., how to resolve collision or whether to disable a package (NIX-80)) or upgrade policies in nix-env (e.g., that a package should be "masked", that is, left untouched by upgrade actions). Example: $ nix-env --set-flag enabled false ghc-6.4
2007-01-29	* Doh!	Eelco Dolstra	1	-2/+0

2007-01-29	* computeStorePathForText: take the references into account when	Eelco Dolstra	5	-6/+18
	computing the store path (NIX-77). This is an important security property in multi-user Nix stores. Note that this changes the store paths of derivations (since the derivation aterms are added using addTextToStore), but not most outputs (unless they use builtins.toFile).
2007-01-29	* Don't capitalise the primop functions.	Eelco Dolstra	1	-76/+81

2007-01-29	* Organise primops.cc a bit better.	Eelco Dolstra	1	-321/+376

2007-01-29	New primitives:	Eelco Dolstra	1	-1/+43
	* `sub' to subtract two numbers. * `stringLength' to get the length of a string. * `substring' to get a substring of a string. These should be enough to allow most string operations to be expressed.
2007-01-29	* filterSource: pass strings to the predicate function instead of	Eelco Dolstra	1	-1/+1
	paths. Paths can have unexpected semantics.
2007-01-24	* Nasty: Glibc clears the TMPDIR environment variable in setuid	Eelco Dolstra	1	-1/+8
	programs, so if a builder uses TMPDIR, then it will fail when executed through nix-setuid-helper. In fact Glibc clears a whole bunch of variables (see sysdeps/generic/unsecvars.h in the Glibc sources), but only TMPDIR should matter in practice. As a workaround, we reinitialise TMPDIR from NIX_BUILD_TOP.
