2004-10-20	* Show error messages from curl.	Eelco Dolstra	1	-1/+1

2004-10-18	* Instead of — use the actual Unicode character. By the way, to	Eelco Dolstra	3	-15/+15
	edit the manual, you should have something like (modify-coding-system-alist 'file "\\.xml\\>" 'utf-8) in your ~/.emacs.
2004-10-14	* Rewrite of package management stuff.	Eelco Dolstra	1	-200/+161

2004-10-14	* In `nix-env -q', sort derivations by name without case	Eelco Dolstra	1	-1/+9
	sensitivity.
2004-10-14	* Split overview chapter into a chapter on package management and a	Eelco Dolstra	6	-455/+384
	chapter on writing Nix expressions.
2004-10-14	* Unindent.	Eelco Dolstra	1	-164/+126

2004-10-13	* Updated the quick start section. Use channels instead of	Eelco Dolstra	1	-105/+83
	downloading Nix expressions and calling nix-pull. This is so user-friendly that even a Mac user can do it! :-)
2004-10-13	* Better introduction.	Eelco Dolstra	3	-120/+123
	* Set notes in a different color than warnings.
2004-09-22	* Make store objects created by substitutes read-only.	Eelco Dolstra	1	-0/+2

2004-09-19	* prevent collision on log directory	Niels Janssen	1	-1/+2

2004-09-12	* Fallback didn't work for subderivations of an unnormalised the main	Eelco Dolstra	1	-44/+7
	derivation, since NormalisationGoal would first run a NormalisationGoal on the subderivation (a no-op, since in a situation where we need fallback the successor is known), and then runs a RealisationGoal on the normal form, which then cannot do a fallback because it doesn't know the derivation expression for which it is a normal form. Tossed out the 2-phase normalisation/realisation in NormalisationGoal and SubstitutionGoal since it's no longer needed - a RealisationGoal will run a NormalisationGoal if necessary.
2004-09-10	* Operation `--delete-generations' to delete generations of a	Eelco Dolstra	8	-33/+100
	profile. Arguments are either generation number, or `old' to delete all non-current generations. Typical use: $ nix-env --delete-generations old $ nix-collect-garbage * istringstream -> string2Int.
2004-09-09	* Remove write permission from store objects after they have been	Eelco Dolstra	1	-0/+4
	added to the store. Bug reported by Martin.
2004-09-09	* A very dirty hack to make setuid installations a bit nicer to use.	Eelco Dolstra	7	-19/+78
	Previously there was the problem that all files read by nix-env etc. should be reachable and readable by the Nix user. So for instance building a Nix expression in your home directory meant that the home directory should have at least g+x or o+x permission so that the Nix user could reach the Nix expression. Now we just switch back to the original user just prior to reading sources and the like. The places where this happens are somewhat arbitrary, however. Any scope that has a live SwitchToOriginalUser object in it is executed as the original user. * Back out r1385. setreuid() sets the saved uid to the new real/effective uid, which prevents us from switching back to the original uid. setresuid() doesn't have this problem (although the manpage has a bug: specifying -1 for the saved uid doesn't leave it unchanged; an explicit value must be specified).
2004-09-09	* Use setre[ug]id() instead of setres[ug]id(), since the former is	Eelco Dolstra	5	-35/+88
	more common than the latter (which exists only on Linux and FreeBSD). We don't really care about dropping the saved IDs since there apparently is no way to quiry them in any case, so it can't influence the build (unlike the effective IDs which are checked by Perl for instance).
2004-09-09	* Set the umask to known value (0022). This is important in a	Eelco Dolstra	1	-0/+6
	setuid installation, since the calling user may have a more fascist umask (say, 0077), which would cause the store objects built by Nix to be unreadable to anyone other than the Nix user.
2004-09-08	* Hack for perl(readmanifest) dependency.	Eelco Dolstra	1	-0/+3

2004-09-06	* Spec file options to create the Nix user and group in the RPM	Eelco Dolstra	1	-9/+18
	pre-install script. By default this is turned off; you should edit the spec file to enable it.
2004-09-06	* Add some variability to RPM spec files: allow setuid options to be	Eelco Dolstra	1	-4/+24
	set on the rpmbuild command line.
2004-08-31	* Main the `substitutes-rev' table again, but now in a way that	Eelco Dolstra	3	-21/+40
	doesn't take \Theta(n^2) space/time complexity.
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.
