2006-02-16	* A simple hack to fix NIX-18: the garbage collector cannot run when	Eelco Dolstra	3	-4/+24
	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.
2006-02-13	* Optional switch "--with-openssl=<PATH>" to use OpenSSL's	Eelco Dolstra	6	-40/+48
	implementations of MD5, SHA-1 and SHA-256. The main benefit is that we get assembler-optimised implementations of MD5 and SHA-1 (though not SHA-256 (at least on x86), unfortunately). OpenSSL's SHA-1 implementation on Intel is twice as fast as ours.
2006-02-13	* Use a union.	Eelco Dolstra	1	-2/+1

2006-02-13	* Override YYMALLOC and YYFREE so that we can call AT[un]protectMemory	Eelco Dolstra	1	-0/+20
	on the Bison parse stack. Otherwise, a garbage collect during parsing could lead to a crash.
2006-02-10	* Enable the --attr in nix-build as well (and add -A as an alias).	Eelco Dolstra	1	-1/+1
	Example: $ nix-build ./all-packages.nix -A xlibs.libX11 So finally it's easy to perform a test build of a Nix expression!
2006-02-10	* In nix-instantiate, allow us to specify a "path" to the	Eelco Dolstra	3	-31/+87
	derivation(s) we're interested, e.g., $ nix-instantiate ./all-packages.nix --attr xlibs.libX11 List elements can also be selected: $ nix-instantiate ./build-for-release.nix --attr 0.subversion This allows a non-ambiguous specification of a derivation. Of course, this should also be added to nix-env and nix-build.
2006-02-10	* Make --parse-only work when not reading from stdin.	Eelco Dolstra	1	-2/+4

2006-02-10	* Cleanup: use the code shared with nix-env.	Eelco Dolstra	1	-64/+15

2006-02-08	* When querying all derivations, filter out syntactically equal derivations.	Eelco Dolstra	1	-12/+36

2006-02-08	* When evaluating, automatically call functions with default arguments.	Eelco Dolstra	1	-4/+23

2006-02-08	* Oops, fix breakage.	Eelco Dolstra	1	-0/+2

2006-02-08	* Refactoring: move derivation evaluation to libexpr.	Eelco Dolstra	4	-187/+209

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.)
2006-02-01	* Print a better error message when writing the patched file (e.g.,	Eelco Dolstra	1	-2/+21
	"No space left on device" instead of "Success"). Reported by Karina Olmos.
2006-02-01	* bsdiff updated to 4.3. This makes Nix depend on libbz2.	Eelco Dolstra	13	-522/+448

2006-02-01	* The "S" bit should be based on the output path, not the derivation path.	Eelco Dolstra	1	-1/+1

2006-01-26	* Oops, the "I" bit in "nix-env -qas" was broken. Reported by Nicolae Vintila.	Eelco Dolstra	1	-1/+1

2006-01-19	* Don't show cycles, they're not very useful.	Eelco Dolstra	1	-2/+4

2006-01-09	* dirOf: return "/", not "", for paths in the root directory. Fixes NIX-26.	Eelco Dolstra	2	-3/+3

2006-01-08	* Resolve all symlink components in the location of the temporary	Eelco Dolstra	2	-4/+25
	build directory (TMPDIR, i.e., /tmp). Fixes NIX-26.
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

2005-12-24	* Documentation fixes.	Eelco Dolstra	1	-2/+2

2005-12-23	* Added a flag `--ignore-liveness' to `nix-store --delete'. It	Eelco Dolstra	3	-6/+12
	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	4	-11/+45
	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	7	-11/+45
	(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	7	-49/+50
	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	5	-31/+52
	much faster.
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.
2005-11-04	* Memoise checkVarDefs since internally produced terms (i.e., not the	Eelco Dolstra	1	-9/+24
	result of parsing) can have very heavy sharing, causing exponential complexity if we naively recurse into them. ATerms are graphs, not trees!
2005-10-29	* Turn off build hooks in nix-push because of an impurity (NIX-21).	Eelco Dolstra	1	-1/+1

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	4	-58/+219
	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.
2005-10-06	* Swap the system and version comparion columns.	Eelco Dolstra	1	-2/+2

2005-10-06	* Only colorise if we are attached to a terminal.	Eelco Dolstra	1	-0/+3

2005-10-06	* New query option: `--compare-versions' or `-c' to compare installed	Eelco Dolstra	2	-19/+89
	versions to available versions, or vice versa. For example, the following compares installed versions to available versions: $ nix-env -qc autoconf-2.59 = 2.59 automake-1.9.4 < 1.9.6 f-spot-0.0.10 - ? firefox-1.0.4 < 1.0.7 ... I.e., there are newer versions available (in the current default Nix expression) for Automake and Firefox, but not for Autoconf, and F-Spot is missing altogether. Conversely, the available versions can be compared to the installed versions: $ nix-env -qac autoconf-2.59 = 2.59 automake-1.9.6 > 1.9.4 bash-3.0 - ? firefox-1.0.7 > 1.0.4 ... Note that bash is available but no version of it is installed. If multiple versions are available for comparison, then the highest is used. E.g., if Subversion 1.2.0 is installed, and Subversion 1.1.4 and 1.2.3 are available, then `nix-env -qc' will print `< 1.2.3', not `> 1.1.4'. If higher versions are available, the version column is printed in red (using ANSI escape codes).
2005-10-05	* log2xml -> nix-log2xml.	Eelco Dolstra	7	-1/+1
