2004-08-31	* Quadruple the Berkeley DB locking limits to get rid of out of memory	Eelco Dolstra	1	-2/+21
	errors while running `nix-store --verify'.
2004-08-30	* Removed nrWaitees field. It was redundant with waitees.size() and	Eelco Dolstra	1	-24/+5
	could get out of sync if multiple input derivations mapped to the same closure expression (since waitees is a set).
2004-08-25	* `--min-age' flag in nix-store and nix-collect-garbage to only delete	Eelco Dolstra	6	-17/+70
	unreachable paths that haven't been used for N hours. For instance, `nix-collect-garbage --min-age 168' only deletes paths that haven't been accessed in the last week. This is useful for instance in the build farm where many derivations can be shared between consecutive builds, and we wouldn't want a garbage collect to throw them all away. We could of course register them as roots, but then we'd to unregister them at some point, which would be a pain to manage. The `--min-age' flag gives us a sort of MRU caching scheme. BUG: this really shouldn't be in gc.cc since that violates mechanism/policy separation.
2004-08-25	* `nix-collect-garbage' now actually performs a garbage collection, it	Eelco Dolstra	5	-73/+102
	doesn't just print the set of paths that should be deleted. So there is no more need to pipe the result into `nix-store --delete' (which doesn't even exist anymore).
2004-08-25	* Put the garbage collector in nix-store: operation `--gc',	Eelco Dolstra	6	-19/+167
	suboperations `--print-live', `--print-dead', and `--delete'. The roots are not determined by nix-store; they are read from standard input. This is to make it easy to customise what the roots are. The collector now no longer fails when store expressions are missing (which legally happens when using substitutes). It never tries to fetch paths through substitutes. TODO: acquire a global lock on the store while garbage collecting. * Removed `nix-store --delete'.
2004-08-24	* Validate derivation names. In particular don't allow spaces.	Eelco Dolstra	1	-8/+19
	* Drop support for the outPath attribute in derivations.
2004-08-20	* The gid should also match.	Eelco Dolstra	1	-1/+1

2004-08-20	* Unbreak programs that are not setuid (such as nix-hash).	Eelco Dolstra	1	-0/+3

2004-08-20	* On systems that have the setresuid() and setresgid() system calls to	Eelco Dolstra	3	-8/+32
	set the real uid and gid to the effective uid and gid, the Nix binaries can be installed as owned by the Nix user and group instead of root, so no root involvement of any kind is necessary. Linux and FreeBSD have these functions.
2004-08-20	* Setuid support for sharing a Nix installation between multiple	Eelco Dolstra	5	-8/+121
	users. If the configure flag `--enable-setuid' is used, the Nix programs nix-env, nix-store, etc. are installed with the setuid bit turned on so that they are executed as the user and group specified by `--with-nix-user=USER' and `--with-nix-group=GROUP', respectively (with defaults `nix' and `nix'). The setuid programs drop all special privileges if they are executed by a user who is not a member of the Nix group. The setuid feature is a quick hack to enable sharing of a Nix installation between users who trust each other. It is not generally secure, since any user in the Nix group can modify (by building an appropriate derivation) any object in the store, and for instance inject trojans into binaries used by other users. The setuid programs are owned by root, not the Nix user. This is because on Unix normal users cannot change the real uid, only the effective uid. Many programs don't work properly when the real uid differs from the effective uid. For instance, Perl will turn on taint mode. However, the setuid programs drop all root privileges immediately, changing all uids and gids to the Nix user and group.
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.
2004-08-18	* The default verbosity level of all Nix commands is now lvlInfo.	Eelco Dolstra	6	-15/+13
	* Builder output is written to standard error by default. * The option `-B' is gone. * The option `-Q' suppresses builder output. The result of this is that most Nix invocations shouldn't need any flags w.r.t. logging.
2004-08-18	* Flag `--no-link' suppresses symlinking to the output path.	Eelco Dolstra	1	-11/+19
	* Handle multiple derivations correctly.
2004-08-13	* WTF? More canonical system name problems ("athlon-linux" instead of	Eelco Dolstra	1	-4/+14
	"i686-linux").
2004-08-11	* The predecessor of a successor need not be present. This in	Eelco Dolstra	1	-4/+6
	particular happens on distributed builds or when using push/pull.
2004-08-05	* Clean up the temporary directory for hook communication (and don't	Eelco Dolstra	1	-0/+1
	print out incorrect "build failed" messages).
2004-08-04	* Every real language has a `map' function.	Eelco Dolstra	2	-2/+19

2004-08-04	* Allow primops with more that 1 arguments.	Eelco Dolstra	7	-104/+102

2004-08-04	* Creating a file nix-support/no-scan in the output path of a	Eelco Dolstra	2	-3/+6
	derivation disables scanning for dependencies. Use at your own risk. This is a quick hack to speed up UML image generation (image are very big, say 1 GB). It would be better if the scanner were faster, and didn't read the whole file into memory.
2004-07-30	* Doh!	Eelco Dolstra	1	-1/+1

2004-07-30	* Use ATerm 2.2.	Eelco Dolstra	2	-4/+4
	* Include bootstrap.sh in dist.
2004-07-30	* A script to generate the Auto* stuff.	Eelco Dolstra	1	-0/+5

2004-07-28	* Nix-build places a symlink `result' in the current directory to the	Eelco Dolstra	1	-1/+10
	store object just built.
2004-07-18	* Don't pass `--with-system'.	Eelco Dolstra	1	-1/+1

2004-07-18	* Slightly better heuristic for picking the canonical system type.	Eelco Dolstra	1	-5/+7
	Now SuSE and Red Hat should yield the same type (`i686-linux'). Mac OS X should now give `powerpc-darwin' (i.e., the version number is gone).
2004-07-09	* Hardcode the system id to be `i686-linux'.	Eelco Dolstra	1	-1/+1

2004-07-06	* Fixed format string error.	Eelco Dolstra	1	-1/+1

2004-07-01	* Don't go into a (sometimes infinite) loop calling the build hook.	Eelco Dolstra	1	-16/+24

2004-07-01	* Nix-instantiate now accepts sets of derivations (just like nix-env).	Eelco Dolstra	1	-0/+9

2004-07-01	* Nix-env operations now by default filter out any derivations for	Eelco Dolstra	1	-9/+28
	system types other than the current system. I.e., `nix-env -i' won't install derivations for other system types, and `nix-env -q' won't show them. The flag `--system-filter SYSTEM' can be used to override the system type used for filtering (but not for building!). The value `*' can be used not to filter anything.
2004-07-01	* Align the columns in the output of `nix-env -q'.	Eelco Dolstra	1	-4/+36

2004-07-01	* Allow the system attribute of derivations to be queried in	Eelco Dolstra	1	-37/+50
	`nix-env -q'. * Queries can now be combined, e.g., `nix-env -q --status --system'.
2004-07-01	* Include some missing headers.	Eelco Dolstra	2	-0/+2

2004-06-29	* Write build logs to disk again.	Eelco Dolstra	1	-1/+29

2004-06-28	* Use ATerm 2.1.	Eelco Dolstra	1	-3/+3

2004-06-28	* By default, `nix-env -i' now deletes previously installed	Eelco Dolstra	2	-3/+58
	derivations with names matching the derivations being installed. The option `--preserve-installed / -P' overrides this behaviour.
2004-06-28	* In a realisation goal, check the result of the corresponding	Eelco Dolstra	1	-0/+6
	normalisation goal.
2004-06-28	* `nix-env -u' now allows a specific version to be specified when	Eelco Dolstra	2	-4/+10
	upgrading. This fixes a bug reported by Martin: $ nix-env -i foo-1.0 $ nix-env -u foo-1.0 upgrading foo-1.0 to foo-1.1
2004-06-28	* Typo.	Eelco Dolstra	1	-1/+1

2004-06-28	* Added a switch `--fallback'. From the manual:	Eelco Dolstra	17	-58/+185
	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	10	-144/+209
	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.
2004-06-25	* Don't throw an exception when a build fails. Just terminate the	Eelco Dolstra	1	-58/+214
	goal and allow the problem to be handled elsewhere (e.g., at top-level).
2004-06-24	* Obsolete.	Eelco Dolstra	1	-162/+0

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	4	-19/+54

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

2004-06-22	* Arghhhhhh	Eelco Dolstra	1	-1/+1

2004-06-22	* Some more diagnostics changes.	Eelco Dolstra	2	-25/+41

2004-06-22	* Nix-instantiate can return multiple store expressions.	Eelco Dolstra	1	-1/+3

2004-06-22	* A utility script `nix-build' that builds Nix expressions and prints	Eelco Dolstra	2	-6/+30
	their output paths (and only that) on standard output.
