2006-05-30	* Not all platforms have sys/select.h.	Eelco Dolstra

2006-05-30	* Don't use badTerm, it gives awful error messages.	Eelco Dolstra

2006-05-29	* Disable the concurrent garbage collector on Cygwin for now.	Eelco Dolstra

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

2006-05-12	* Support for srcdir != builddir (NIX-41).	Eelco Dolstra

2006-05-11	* 64-bit compatibility fixes (for problems revealed by building on an Athlon	Eelco Dolstra
	64 running 64-bit SUSE). A patched ATerm library is required to run Nix succesfully.
2006-05-08	* GCC 2.95 compatibility.	Eelco Dolstra

2006-05-08	* Allow function argument default values to refer to other arguments	Eelco Dolstra
	of the function. Implements NIX-45.
2006-05-08	* Show evaluation stats when NIX_SHOW_STATS=1.	Eelco Dolstra

2006-05-04	* Use the new ATermMap.	Eelco Dolstra

2006-05-02	* Optimise null-ary term builders. Also declare all term builder	Eelco Dolstra
	functions as pure, which might improve performance a bit.
2006-05-02	* Use a linked list of substitutions. This reduces the amount of	Eelco Dolstra
	copying.
2006-05-02	* Removed a bunch of ATreverses.	Eelco Dolstra

2006-05-02	* Huge reduction in memory use (2/3 or so on large nix-env -qas	Eelco Dolstra
	operations): share ATermMaps between DrvInfos.
2006-05-02	* Memory reduction: replaced expensive calls to ATmakeApplList by	Eelco Dolstra
	ATmakeApplArray, and got rid of ATreverse in substitute().
2006-05-02	* Some preliminaries towards NIX-45.	Eelco Dolstra

2006-05-01	* Disallow unescaped $ in string literals.	Eelco Dolstra

2006-05-01	* String interpolation. Expressions like	Eelco Dolstra
	"--with-freetype2-library=" + freetype + "/lib" can now be written as "--with-freetype2-library=${freetype}/lib" An arbitrary expression can be enclosed within ${...}, not just identifiers. * Escaping in string literals: \n, \r, \t interpreted as in C, any other character following \ is interpreted as-is. * Newlines are now allowed in string literals.
2006-05-01	* Allow string concatenations involving derivations, e.g.,	Eelco Dolstra
	configureFlags = "--with-freetype2-library=" + freetype + "/lib";
2006-03-24	* Print a more useful stack trace when an error occurs deep in the	Eelco Dolstra
	derivation dependency graph.
2006-03-23	* In `nix-env', look for derivations inside attribute sets that have	Eelco Dolstra
	the `recurseForDerivations' attribute set to `true'.
2006-03-23	* Hm.	Eelco Dolstra

2006-03-10	* Allow `make check' to work in directories that have symlink	Eelco Dolstra
	components.
2006-03-10	* `nix-env -qa --description' shows human-readable descriptions of	Eelco Dolstra
	packages (provided that they have a `meta.description' attribute). E.g., $ ./src/nix-env/nix-env -qa --description gcc gcc-4.0.2 GNU Compiler Collection, 4.0.x (cross-compiler for sparc-linux) gcc-4.0.2 GNU Compiler Collection, 4.0.x (cross-compiler for mips-linux) gcc-4.0.2 GNU Compiler Collection, 4.0.x (cross-compiler for arm-linux) gcc-4.0.2 GNU Compiler Collection, 4.0.x
2006-03-10	* In theory, this should reduce the number of ATermMap	Eelco Dolstra
	re-allocations.
2006-03-10	* `nix-env -q' now accepts arguments that allow specific derivations	Eelco Dolstra
	to be queried, e.g., `nix-env -qa firefox'. This does require the argument '' to be passed if one wants information about all derivations, so the old `nix-env -qa' now is `nix-env -qa ""'.
2006-03-09	* Ugh, printHash() was very inefficient because it used	Eelco Dolstra
	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

2006-03-09	* Big speedup (factor > 2.5) in all nix-env operations that do actual	Eelco Dolstra
	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
	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
	Nix expression assertion failures.
2006-03-06	* GCC 4.1 compatibility.	Eelco Dolstra

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

2006-03-01	* Flags `--to-base32' and `--to-base16' to convert between hex and	Eelco Dolstra
	base-32 hashes.
2006-03-01	* Ouch, parseHash32 was completely broken. All digits >= 4 were	Eelco Dolstra
	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

2006-03-01	* Close the database before the destructor runs.	Eelco Dolstra

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

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

2006-03-01	* Generate valid HTML.	Eelco Dolstra

2006-03-01	* Remove dead code.	Eelco Dolstra

2006-02-17	* In "nix-env -i", print a warning if there are multiple derivations	Eelco Dolstra
	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
	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
	("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
	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
	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
	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

2006-02-13	* Override YYMALLOC and YYFREE so that we can call AT[un]protectMemory	Eelco Dolstra
	on the Bison parse stack. Otherwise, a garbage collect during parsing could lead to a crash.
