2007-03-30	* Work around a bug in Apple's GCC preprocessor.	Eelco Dolstra	1	-2/+2

2007-01-14	* Option --argstr for passing string arguments easily. (NIX-75)	Eelco Dolstra	1	-1/+1

2007-01-13	* Removed chroot support.	Eelco Dolstra	1	-6/+0

2006-12-08	* Kill a build if it has gone for more than a certain number of	Eelco Dolstra	1	-14/+18
	seconds without producing output on stdout or stderr (NIX-65). This timeout can be specified using the `--max-silent-time' option or the `build-max-silent-time' configuration setting. The default is infinity (0). * Fix a tricky race condition: if we kill the build user before the child has done its setuid() to the build user uid, then it won't be killed, and we'll potentially lock up in pid.wait(). So also send a conventional kill to the child.
2006-12-07	* Move setuidCleanup() to libutil.	Eelco Dolstra	2	-25/+0

2006-12-06	* nix-setuid-helper: allow running programs under a different uid.	Eelco Dolstra	2	-11/+24

2006-12-05	* Allow unprivileged users to run the garbage collector and to do	Eelco Dolstra	1	-1/+0
	`nix-store --delete'. But unprivileged users are not allowed to ignore liveness. * `nix-store --delete --ignore-liveness': ignore the runtime roots as well.
2006-12-05	* In addPermRoot, check that the root that we just registered can be	Eelco Dolstra	1	-1/+1
	found by the garbage collector. This addresses NIX-71 and is a particular concern in multi-user stores.
2006-12-04	* Daemon mode (`nix-worker --daemon'). Clients connect to the server	Eelco Dolstra	1	-0/+6
	via the Unix domain socket in /nix/var/nix/daemon.socket. The server forks a worker process per connection. * readString(): use the heap, not the stack. * Some protocol fixes.
2006-12-04	* Install the worker in bindir, not libexecdir.	Eelco Dolstra	2	-0/+2
	* Allow the worker path to be overriden through the NIX_WORKER environment variable.
2006-12-03	* Doh.	Eelco Dolstra	2	-1/+4

2006-12-03	* Don't run setuid root when build-users is empty.	Eelco Dolstra	1	-1/+1
	* Send startup errors to the client.
2006-12-03	* Removed `build-allow-root'.	Eelco Dolstra	2	-0/+5
	* Added `build-users-group', the group under which builds are to be performed. * Check that /nix/store has 1775 permission and is owner by the build-users-group.
2006-12-03	* Use setreuid if setresuid is not available.	Eelco Dolstra	1	-6/+12

2006-12-02	* Remove most of the old setuid code.	Eelco Dolstra	1	-4/+56
	* Much simpler setuid code for the worker in slave mode.
2006-11-30	* Refactoring. There is now an abstract interface class StoreAPI	Eelco Dolstra	1	-2/+3
	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.
2006-11-18	* Turn off synchronisation between C and C++ I/O functions. This	Eelco Dolstra	1	-0/+2
	gives a huge speedup in operations that read or write from standard input/output. (So libstdc++'s I/O isn't that bad, you just have to call std::ios::sync_with_stdio(false).) For instance, `nix-store --register-substitutes' went from 1.4 seconds to 0.1 seconds on a certain input. Another victory for Valgrind.
2006-09-27	* Fix setuid builds.	Eelco Dolstra	1	-4/+0

2006-09-04	* Move setuid stuff to libutil.	Eelco Dolstra	1	-133/+0
	* Install libexpr header files.
2006-09-04	* Don't need extern "C".	Eelco Dolstra	1	-2/+0

2006-09-04	* Use a proper namespace.	Eelco Dolstra	2	-14/+27
	* 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

2006-08-29	* Support singleton values and nested lists again in `args', but print	Eelco Dolstra	1	-7/+4
	a warning.
2006-08-10	* New configuration setting `build-max-jobs' which sets the default	Eelco Dolstra	1	-0/+7
	for the `-j' flag (i.e., the maximum number of jobs to execute in parallel). Useful on multi-processor machines.
2006-07-20	* Use $(libexecdir) to find find-runtime-roots.pl.	Eelco Dolstra	2	-0/+2

2006-07-06	* Allow the canonical system name to be specified at runtime in the	Eelco Dolstra	1	-0/+2
	Nix config file.
2006-05-12	* Support for srcdir != builddir (NIX-41).	Eelco Dolstra	1	-1/+2

2006-03-10	* Allow `make check' to work in directories that have symlink	Eelco Dolstra	1	-23/+2
	components.
2006-03-01	* Close the database before the destructor runs.	Eelco Dolstra	1	-0/+3

2006-01-09	* dirOf: return "/", not "", for paths in the root directory. Fixes NIX-26.	Eelco Dolstra	1	-1/+1

2005-11-04	* Install signal handlers for SIGTERM and SIGHUP. This ensures that	Eelco Dolstra	1	-0/+4
	Nix is properly shut down when it receives those signals. In particular this ensures that killing the garbage collector doesn't cause a subsequent database recovery.
2005-10-17	* Beginning of secure multi-user Nix stores. If Nix is started as	Eelco Dolstra	1	-0/+5
	root (or setuid root), then builds will be performed under one of the users listed in the `build-users' configuration variables. This is to make it impossible to influence build results externally, allowing locally built derivations to be shared safely between users (see ASE-2005 paper). To do: only one builder should be active per build user.
2005-07-22	* Build dynamic libraries.	Eelco Dolstra	1	-2/+2

2005-02-01	* A GC setting `gc-keep-outputs' to specify whether output paths of	Eelco Dolstra	2	-0/+2
	derivations should be kept.
2005-02-01	* nix-store, nix-instantiate: added an option `--add-root' to	Eelco Dolstra	2	-1/+27
	immediately add the result as a permanent GC root. This is the only way to prevent a race with the garbage collector. For instance, the old style ln -s $(nix-store -r $(nix-instantiate foo.nix)) \ /nix/var/nix/gcroots/result has two time windows in which the garbage collector can interfere (by GC'ing the derivation and the output, respectively). On the other hand, nix-store --add-root /nix/var/nix/gcroots/result -r \ $(nix-instantiate --add-root /nix/var/nix/gcroots/drv \ foo.nix) is safe. * nix-build: use `--add-root' to prevent GC races.
2005-01-31	* Automatically remove temporary root files.	Eelco Dolstra	1	-0/+14

2005-01-28	* Use NIX_STORE environment variable to locate the store (in addition	Eelco Dolstra	1	-1/+1
	to NIX_STORE_DIR) so that Nix invocations in builders in `make check' work correctly if the store doesn't exist.
2005-01-19	* Renamed `normalise.cc' -> `build.cc', `storeexprs.cc' ->	Eelco Dolstra	1	-2/+2
	`derivations.cc', etc. * Store the SHA-256 content hash of store paths in the database after they have been built/added. This is so that we can check whether the store has been messed with (a la `rpm --verify'). * When registering path validity, verify that the closure property holds.
2005-01-14	* Start move towards SHA-256 hashes instead of MD5.	Eelco Dolstra	1	-4/+4
	* Start cleaning up unique store path generation (they weren't always unique; in particular the suffix ("-aterm-2.2", "-builder.sh") was not part of the hash, therefore changes to the suffix would cause multiple store objects with the same hash).
2004-10-29	* Drop ATmake / ATMatcher also in handling store expressions.	Eelco Dolstra	1	-0/+6

2004-10-25	* Allow certain operations to succeed even if we don't have write	Eelco Dolstra	1	-0/+2
	permission to the Nix store or database. E.g., `nix-env -qa' will work, but `nix-env -qas' won't (the latter needs DB access). The option `--readonly-mode' forces this mode; otherwise, it's only activated when the database cannot be opened.
2004-10-25	* Revert r1594 - it didn't solve the problem. Instead add	Eelco Dolstra	1	-1/+1
	svn-revision to distributions, which should fix it.
2004-10-25	* Make sure that the prerelease version is included in `--version'.	Eelco Dolstra	1	-1/+1

2004-09-10	* Operation `--delete-generations' to delete generations of a	Eelco Dolstra	1	-3/+1
	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	* A very dirty hack to make setuid installations a bit nicer to use.	Eelco Dolstra	1	-12/+49
	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	1	-4/+4
	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.
2004-08-20	* 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	1	-8/+21
	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.
