2006-02-16	* Allow the size of the GC reserved file to be specified in nix.conf	Eelco Dolstra	3	-9/+18
	through the new `gc-reserved-space' option.
2006-02-16	* A simple hack to fix NIX-18: the garbage collector cannot run when	Eelco Dolstra	2	-3/+23
	the disk is full (because to delete something from the Nix store, we need a Berkeley DB transaction, which takes up disk space). Under normal operation, we make sure that there exists a file /nix/var/nix/db/reserved of 1 MB. When running the garbage collector, we delete that file before we open the Berkeley DB environment.
2006-02-03	* Use setsid instead of setpgrp in child processes. This not only	Eelco Dolstra	1	-6/+8
	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	1	-0/+1
	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.)
2005-12-25	* More GCC 2.95 compatibility.	Eelco Dolstra	1	-1/+1

2005-12-25	* Hack around a GCC 2.95 bug.	Eelco Dolstra	1	-2/+2

2005-12-24	* GCC 2.95 compatibility.	Eelco Dolstra	1	-1/+1

2005-12-23	* Added a flag `--ignore-liveness' to `nix-store --delete'. It	Eelco Dolstra	2	-3/+4
	deletes a path even if it is reachable from a root. However, it won't delete a path that still has referrers (since that would violate store invariants). Don't try this at home. It's a useful hack for recovering from certain situations in a somewhat clean way (e.g., holes in closures due to disk corruption).
2005-12-23	* Revived the old "nix-store --delete" operation that deletes the	Eelco Dolstra	2	-10/+22
	specified paths from the Nix store. However, this operation is safe: it refuses to delete anything that the garbage collector wouldn't delete.
2005-12-15	* `nix-store --gc' prints out the number of bytes freed on stdout	Eelco Dolstra	4	-6/+12
	(even when it is interrupted by a signal).
2005-12-15	* Split the database upgrade into multiple transactions to prevent	Eelco Dolstra	1	-2/+11
	Berkeley DB from running out of locks.
2005-12-13	* Change `referer' to `referrer' throughout. In particular, the	Eelco Dolstra	5	-39/+40
	nix-store query options `--referer' and `--referer-closure' have been changed to `--referrer' and `--referrer-closure' (but the old ones are still accepted for compatibility).
2005-12-12	* Automatically delete the old referers table.	Eelco Dolstra	3	-5/+31

2005-12-12	* Fix NIX-23: quadratic complexity in maintaining the referers	Eelco Dolstra	4	-40/+107
	mapping. The referer table is replaced by a referrer table (note spelling fix) that stores each referrer separately. That is, instead of having referer[P] = {Q_1, Q_2, Q_3, ...} we store referer[(P, Q_1)] = "" referer[(P, Q_2)] = "" referer[(P, Q_3)] = "" ... To find the referrers of P, we enumerate over the keys with a value lexicographically greater than P. This requires the referrer table to be stored as a B-Tree rather than a hash table. (The tuples (P, Q) are stored as P + null-byte + Q.) Old Nix databases are upgraded automatically to the new schema.
2005-12-09	* Use Berkeley DB 4.4's process registry feature to recover from	Eelco Dolstra	2	-102/+56
	crashed Nix instances, and toss out our own recovery code.
2005-12-06	* Require Berkeley DB 4.4.	Eelco Dolstra	1	-1/+3
	* Checkpoint after an upgrade.
2005-11-16	* Did something useful while waiting at IAD: reference scanning is now	Eelco Dolstra	3	-30/+45
	much faster.
2005-10-29	* Repair the referers table from the references table.	Rob Vermaas	1	-0/+3

2005-10-20	* Prevent uids from being used for more than one build	Eelco Dolstra	1	-36/+120
	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	1	-1/+0

2005-10-17	* Also kill all processes of the build user after the build. This is	Eelco Dolstra	1	-0/+8
	critical to prevent certain kinds of 0wnage.
2005-10-17	* Before starting a build under some uid, kill all current processes	Eelco Dolstra	1	-0/+48
	running under that uid.
2005-10-17	* Check that the build result is owned by the build user, and that	Eelco Dolstra	1	-2/+13
	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	1	-68/+17
	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	3	-58/+214
	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.
2005-09-22	* Lets not go wild with templates.	Eelco Dolstra	1	-4/+6

2005-09-22	* Parse multi-valued options.	Eelco Dolstra	2	-15/+34

2005-09-21	* Configuration options for trusted local builds.	Eelco Dolstra	2	-5/+12

2005-09-20	* Typo.	Eelco Dolstra	1	-1/+1

2005-07-22	* Build dynamic libraries.	Eelco Dolstra	1	-2/+2

2005-05-10	* Ignore (with a warning) invalid garbage collector roots.	Eelco Dolstra	1	-1/+6

2005-05-10	* Typo.	Eelco Dolstra	1	-1/+1

2005-05-09	* Automatically upgrade the Berkeley DB environment if necessary.	Eelco Dolstra	2	-106/+133

2005-05-07	* Don't try to register GC roots in read-only mode.	Eelco Dolstra	1	-2/+2

2005-05-04	* Idem (constness fix).	Eelco Dolstra	1	-2/+2
	* `compare' in GCC 2.95 is broken.
2005-05-04	* GCC 2.95 compatibility fix in constness; strangely, I think this	Eelco Dolstra	1	-1/+1
	should not have worked at all.
2005-04-13	* Remove redundant message.	Eelco Dolstra	1	-4/+0

2005-04-12	* Garbage collector fix: allow deletion of paths that have invalid	Eelco Dolstra	1	-4/+4
	(but substitutable) referers.
2005-04-11	* Slightly nicer message.	Eelco Dolstra	1	-3/+3

2005-04-07	* `nix-store --add-fixed' to preload the outputs of fixed-output	Eelco Dolstra	2	-2/+68
	derivations. This is mostly to simplify the implementation of nix-prefetch-{url, svn}, which now work properly in setuid installations. * Enforce valid store names in `nix-store --add / --add-fixed'.
2005-03-25	* When finding live paths, the deriver need not be valid.	Eelco Dolstra	1	-1/+4

2005-03-25	* `nix-store --verify': repair bad referer mappings.	Eelco Dolstra	1	-6/+16

2005-03-24	* Create missing log and temproots directories automatically (reported	Eelco Dolstra	2	-13/+12
	by Rob).
2005-03-23	* Export the references graph to the build hook.	Eelco Dolstra	1	-14/+30

2005-03-23	* `nix-store --register-validity': allow a path to refer to a path	Eelco Dolstra	2	-13/+50
	listed later in the list of new valid paths.
2005-03-23	* nix-store: `--isvalid' -> `--check-validity', `--validpath' ->	Eelco Dolstra	2	-1/+2
	`--register-validity'. * `nix-store --register-validity': read arguments from stdin, and allow the references and deriver to be set.
2005-03-14	* Bug in clearSubstitutes().	Eelco Dolstra	1	-1/+2

2005-03-03	* Don't use fork() in copyPath(), but a string buffer.	Eelco Dolstra	1	-47/+14

2005-03-03	* Increase Berkeley DB limits a bit more.	Eelco Dolstra	2	-7/+26
	* Maintain the cleanup invariant in clearSubstitutes().
2005-03-02	* `nix-store -q --hash' to quickly query the hash of the contents of a	Eelco Dolstra	2	-0/+11
	store path (which is stored in the database).
