2006-03-09	* Ugh, printHash() was very inefficient because it used	Eelco Dolstra	1	-5/+7
	ostringstreams. Around 11% of execution time was spent here (now it's 0.5%).
2006-03-09	* Regression: semantics of the result of getDerivation() changed.	Eelco Dolstra	1	-2/+2

2006-03-09	* Big speedup (factor > 2.5) in all nix-env operations that do actual	Eelco Dolstra	2	-3/+14
	instantiation, e.g. "nix-env -i" and "nix-env -qas" (but not "nix-env -qa"). It turns out that many redundant calls to addToStore(path) were made, which reads and hashes the entire path. For instance, the bash bootstrap binary in Nixpkgs would be read and hashed many times. As a result nix-env would spend around 92% of its time in the function sha256_block (according to callgrind). Some simple memoization fixes this.
2006-03-08	* When obtaining derivations from Nix expressions, ignore all	Eelco Dolstra	3	-70/+98
	expressions that cause an assertion failure (like `assert system == "i686-linux"'). This allows all-packages.nix in Nixpkgs to be used on all platforms, even if some Nix expressions don't work on all platforms. Not sure if this is a good idea; it's a bit hacky. In particular, due to laziness some derivations might appear in `nix-env -qa' but disappear in `nix-env -qas' or `nix-env -i'. Commit 5000!
2006-03-08	* Some refactoring of the exception handling code so that we can catch	Eelco Dolstra	5	-22/+45
	Nix expression assertion failures.
2006-03-06	* GCC 4.1 compatibility.	Eelco Dolstra	1	-1/+1

2006-03-06	* `nix-env (-i\|-u) --dry-run' now shows exactly which missing paths	Eelco Dolstra	9	-22/+120
	will be built or substituted.
2006-03-06	* Regularise help text a bit.	Eelco Dolstra	4	-4/+4

2006-03-01	* Flags `--to-base32' and `--to-base16' to convert between hex and	Eelco Dolstra	1	-2/+19
	base-32 hashes.
2006-03-01	* Ouch, parseHash32 was completely broken. All digits >= 4 were	Eelco Dolstra	1	-1/+1
	parsed as 4. For a moment I worried that printHash32 was broken, and that would have been really, really bad ;-)
2006-03-01	* db.hh shouldn't depend on the Berkeley DB headers.	Eelco Dolstra	5	-3/+13

2006-03-01	* Close the database before the destructor runs.	Eelco Dolstra	4	-0/+15

2006-03-01	* Uninitialised variable. Fixes the --delete test.	Eelco Dolstra	1	-1/+1

2006-03-01	* Wrong delete. Thanks valgrind.	Eelco Dolstra	1	-1/+1

2006-03-01	* Generate valid HTML.	Eelco Dolstra	1	-15/+22

2006-03-01	* Remove dead code.	Eelco Dolstra	1	-30/+0

2006-02-17	* In "nix-env -i", print a warning if there are multiple derivations	Eelco Dolstra	1	-24/+16
	with the same name and version number, and pick the first one (this means that the order in which channels appear in ~/.nix-channels matters). E.g.: $ nix-env ii aterm warning: there are multiple derivations named `aterm-2.4.2'; using the first one installing `aterm-2.4.2'
2006-02-17	* Fix for NIX-31: "nix-env -i foo" installing all derivations named	Eelco Dolstra	1	-8/+62
	foo. Now it will only install the one with the highest version number.
2006-02-17	* Fix the infamous NIX-17: nix-env -i prints misleading messages	Eelco Dolstra	1	-7/+9
	("installing `foo'" followed by "uninstalling `foo'").
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	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).
