2006-06-19	* Oops.	Eelco Dolstra

2006-06-19	* _exit() doesn't seem to work right on Cygwin.	Eelco Dolstra

2006-06-16	* Show when we're blocked waiting for a lock.	Eelco Dolstra

2006-05-31	* For fixed-output derivations, pass the environment variables listed	Eelco Dolstra
	in the attribute variable `impureEnvVars' from the caller to the builder.
2006-05-30	* Not all platforms have sys/select.h.	Eelco Dolstra

2006-05-24	* Some Cygwin fixes.	Eelco Dolstra

2006-03-06	* `nix-env (-i\|-u) --dry-run' now shows exactly which missing paths	Eelco Dolstra
	will be built or substituted.
2006-03-01	* db.hh shouldn't depend on the Berkeley DB headers.	Eelco Dolstra

2006-02-03	* Use setsid instead of setpgrp in child processes. This not only	Eelco Dolstra
	creates a new process group but also a new session. New sessions have no controlling tty, so child processes like ssh cannot open /dev/tty (which is bad).
2006-02-02	* When killing a build hook, kill the entire process group (as	Eelco Dolstra
	intended). This ensures that any ssh child processes to remote machines are also killed, and thus the Nix process on the remote machine also exits. Without this, the remote Nix process will continue until it exists or until its stdout buffer gets full and it locks up. (Partially fixes NIX-35.)
2005-11-16	* Did something useful while waiting at IAD: reference scanning is now	Eelco Dolstra
	much faster.
2005-10-20	* Prevent uids from being used for more than one build	Eelco Dolstra
	simultaneously. We do this using exclusive locks on uid files in /nix/var/nix/userpool, e.g., /nix/var/nix/userpool/123 for uid 123.
2005-10-19	* Oops. Fixed-output derivations were broken.	Eelco Dolstra

2005-10-17	* Also kill all processes of the build user after the build. This is	Eelco Dolstra
	critical to prevent certain kinds of 0wnage.
2005-10-17	* Before starting a build under some uid, kill all current processes	Eelco Dolstra
	running under that uid.
2005-10-17	* Check that the build result is owned by the build user, and that	Eelco Dolstra
	nobody else has write permission to the build result. This catches most hack attempts.
2005-10-17	* Don't use FIFOs to make Nix create the output path on behalf of the	Eelco Dolstra
	builder. Instead, require that the Nix store has sticky permission (S_ISVTX); everyone can created files in the Nix store, but they cannot delete, rename or modify files created by others.
2005-10-17	* Beginning of secure multi-user Nix stores. If Nix is started as	Eelco Dolstra
	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.
2005-09-20	* Typo.	Eelco Dolstra

2005-05-10	* Typo.	Eelco Dolstra

2005-04-13	* Remove redundant message.	Eelco Dolstra

2005-04-11	* Slightly nicer message.	Eelco Dolstra

2005-03-24	* Create missing log and temproots directories automatically (reported	Eelco Dolstra
	by Rob).
2005-03-23	* Export the references graph to the build hook.	Eelco Dolstra

2005-02-23	* When multiple derivations are specified in `nix-store -r', don't	Eelco Dolstra
	continue building when one fails unless `--keep-going' is specified. * When `--keep-going' is specified, print out the set of failing derivations at the end (otherwise it can be hard to find out which failed).
2005-02-22	* Support for fixed-output hashes over directory trees (i.e., over the	Eelco Dolstra
	NAR dump of the path).
2005-02-22	* Compatibility hack so that Nixpkgs can continue to do hash checking	Eelco Dolstra
	in `fetchurl' in Nix <= 0.7, but doesn't in Nix 0.8.
2005-02-18	* Subtle bug in the builder: if a subgoal that is instantiated	Eelco Dolstra
	multiple times is also a top-level goal, then the second and later instantiations would never be created because there would be a stable pointer to the first one that would keep it alive in the WeakGoalMap. * Some tracing code for debugging this kind of problem.
2005-02-17	* Put build logs in $prefix/var/nix/log/drvs/.	Eelco Dolstra

2005-02-11	* Input sources should be in the set of all referenceable paths too.	Eelco Dolstra

2005-02-09	* Propagate the deriver of a path through the substitute mechanism.	Eelco Dolstra
	* Removed some dead code (successor stuff) from nix-push. * Updated terminology in the tests (store expr -> drv path). * Check that the deriver is set properly in the tests.
2005-02-08	* Updated `nix-store --verify' to the new schema.	Eelco Dolstra

2005-02-07	* Maintain a database table (`derivers') that maps output paths to the	Eelco Dolstra
	derivation that produced them. * `nix-store -qd PATH' prints out the derivation that produced a path.
2005-02-01	* Add missing files to dist.	Eelco Dolstra
	* Fix GC and substitute bugs related to self-references. Add a regression test.
2005-01-31	* Start of concurrent garbage collection. Processes write temporary	Eelco Dolstra
	roots to a per-process temporary file in /nix/var/nix/temproots while holding a write lock on that file. The garbage collector acquires read locks on all those files, thus blocking further progress in other Nix processes, and reads the sets of temporary roots.
2005-01-27	* Fix and simplify the garbage collector (it's still not concurrent,	Eelco Dolstra
	though). In particular it's now much easier to register a GC root. Just place a symlink to whatever store path it is that you want to keep in /nix/var/nix/gcroots.
2005-01-25	* Maintain the references/referers relation also for derivations.	Eelco Dolstra
	This simplifies garbage collection and `nix-store --query --requisites' since we no longer need to treat derivations specially. * Better maintaining of the invariants, e.g., setReferences() can only be called on a valid/substitutable path.
2005-01-25	* Simplification: registerSubstitutes -> registerSubstitute. We no	Eelco Dolstra
	longer need the former since there we no longer have the substitutes-rev table (which triggered a O(n^2) cost in updating them).
2005-01-25	* Really fix the substitute mechanism, i.e., ensure the closure	Eelco Dolstra
	invariant by registering references through the manifest. * Added a test for nix-pull.
2005-01-25	* Fix the `--fallback' switch.	Eelco Dolstra
	* Fix the substitutes tests.
2005-01-25	* Fix the build hook mechanism; pass the pointer graph to the hook.	Eelco Dolstra

2005-01-25	* In nix-store: change `--build' back to `--realise'. Also brought	Eelco Dolstra
	back the query flag `--force-realise'. * Fixed some of the tests.
2005-01-20	* Terminology fixes.	Eelco Dolstra

2005-01-20	* Another change to low-level derivations. The last one this year, I	Eelco Dolstra
	promise :-) This allows derivations to specify on what output paths of input derivations they are dependent. This helps to prevent unnecessary downloads. For instance, a build might be dependent on the `devel' and `lib' outputs of some library component, but not the `docs' output.
2005-01-19	* Renamed `normalise.cc' -> `build.cc', `storeexprs.cc' ->	Eelco Dolstra
	`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.
