2014-12-05	Use posix_spawn to run the pager	Eelco Dolstra	3	-10/+39
	In low memory environments, "nix-env -qa" failed because the fork to run the pager hit the kernel's overcommit limits. Using posix_spawn gets around this. (Actually, you have to use posix_spawn with the undocumented POSIX_SPAWN_USEVFORK flag, otherwise it just uses fork/exec...)
2014-12-02	Make all ExternalValueBase functions const	Shea Levy	4	-15/+15

2014-12-02	Allow external code using libnixexpr to add types	Shea Levy	5	-0/+108
	Code that links to libnixexpr (e.g. plugins loaded with importNative, or nix-exec) may want to provide custom value types and operations on values of those types. For example, nix-exec is currently using sets where a custom IO value type would be more appropriate. This commit provides a generic hook for such types in the form of tExternal and the ExternalBase virtual class, which contains all functions necessary for libnixexpr's type-polymorphic functions (e.g. `showType`) to be implemented.
2014-11-25	Add a primop for regular expression pattern matching	Eelco Dolstra	3	-5/+57
	The function ‘builtins.match’ takes a POSIX extended regular expression and an arbitrary string. It returns ‘null’ if the string does not match the regular expression. Otherwise, it returns a list containing substring matches corresponding to parenthesis groups in the regex. The regex must match the entire string (i.e. there is an implied "^<pat>$" around the regex). For example: match "foo" "foobar" => null match "foo" "foo" => [] match "f(o+)(.)" "foooobar" => ["oooo" "bar"] match "(./)?([^/])" "/dir/file.nix" => ["/dir/" "file.nix"] match "(./)?([^/])" "file.nix" => [null "file.nix"] The following example finds all regular files with extension .nix or .patch underneath the current directory: let findFiles = pat: dir: concatLists (mapAttrsToList (name: type: if type == "directory" then findFiles pat (dir + "/" + name) else if type == "regular" && match pat name != null then [(dir + "/" + name)] else []) (readDir dir)); in findFiles ".\\.(nix\|patch)" (toString ./.)
2014-11-25	forceString(): Accept pos argument	Eelco Dolstra	3	-5/+5

2014-11-24	Build derivations in a more predictable order	Eelco Dolstra	1	-7/+41
	Derivations are now built in order of derivation name, so a package named "aardvark" is built before "baboon". Fixes #399.
2014-11-24	Don't create unnecessary substitution goals for derivations	Eelco Dolstra	1	-0/+5

2014-11-20	import derivation: cleanup	Shea Levy	1	-8/+11
	Before this there was a bug where a `find` was being called on a not-yet-sorted set. The code was just a mess before anyway, so I cleaned it up while fixing it.
2014-11-19	Disable vacuuming the DB after garbage collection	Eelco Dolstra	1	-1/+1
	Especially in WAL mode on a highly loaded machine, this is not a good idea because it results in a WAL file of approximately the same size ad the database, which apparently cannot be deleted while anybody is accessing it.
2014-11-19	nix-daemon: Call exit(), not _exit()	Eelco Dolstra	3	-5/+8
	This was preventing destructors from running. In particular, it was preventing the deletion of the temproot file for each worker process. It may also have been responsible for the excessive WAL growth on Hydra (due to the SQLite database not being closed properly). Apparently broken by accident in 8e9140cfdef9dbd1eb61e4c75c91d452ab5e4a74.
2014-11-19	Clean up temp roots in a more C++ way	Eelco Dolstra	3	-26/+13

2014-11-17	Fix message	Eelco Dolstra	1	-1/+1

2014-11-15	realiseContext: Handle all context types	Shea Levy	1	-2/+2
	Avoids an assertion
2014-11-15	Add functors (callable attribute sets).	Shea Levy	2	-1/+13
	With this, attribute sets with a `__functor` attribute can be applied just like normal functions. This can be used to attach arbitrary metadata to a function without callers needing to treat it specially.
2014-11-14	Don't use ADDR_LIMIT_3GB	Eelco Dolstra	1	-1/+1
	This gives 32-bit builds on x86_64-linux more memory.
2014-11-12	Make ~DerivationGoal more reliable	Eelco Dolstra	1	-7/+3

2014-11-04	nix-store --gc: Don't warn about missing manifests directory	Eelco Dolstra	1	-1/+2

2014-10-31	nix-daemon: Get peer credentials on Mac OS X	Eelco Dolstra	1	-19/+52
	This makes allowed-users and trusted-users work on Mac OS X.
2014-10-31	Improve error message if the daemon worker fails to start	Eelco Dolstra	2	-3/+2

2014-10-31	Fix more warnings	Eelco Dolstra	1	-11/+1

2014-10-31	Shut up a clang warning	Eelco Dolstra	1	-1/+1

2014-10-29	Remove comments claiming we use a private PID namespace	Eelco Dolstra	1	-8/+1
	This is no longer the case since 524f89f1399724e596f61faba2c6861b1bb7b9c5.
2014-10-20	Fix build on gcc < 4.7	Shea Levy	2	-0/+16

2014-10-20	Revert "Drop support for pre-c++11 compilers."	Shea Levy	1	-1/+2
	The breakage this fixed can be worked around without removing support. This reverts commit 84a13dc576496f1227665259c61f86184f452f51.
2014-10-20	Improve printing of ASTs	Eelco Dolstra	3	-16/+58

2014-10-18	Drop support for pre-c++11 compilers.	Shea Levy	1	-2/+1
	In particular, gcc 4.6's std::exception::~exception has an exception specification in c++0x mode, which requires us to use that deprecated feature in nix (and led to breakage after some recent changes that were valid c++11). nix already uses several c++11 features and gcc 4.7 has been around for over 2 years.
2014-10-17	Export realiseContext in libnixexpr	Shea Levy	2	-9/+11
	Useful for importNative plugins
2014-10-14	nix-store -q: Check for conflicting flags	Eelco Dolstra	1	-4/+12
	Fixes #364.
2014-10-14	Remove redundant space in usage errors	Eelco Dolstra	1	-1/+1

2014-10-14	Improved error message when encountering unsupported file types	Eelco Dolstra	1	-3/+3
	Fixes #269.
2014-10-09	mkList: Scrub better	Eelco Dolstra	2	-2/+3
	Clearing v.app.right was not enough, because the length field of a list only takes 32 bits, so the most significant 32 bits of v.app.left (a.k.a. v.thunk.env) would remain. This could cause Boehm GC to interpret it as a valid pointer. This change reduces maximum RSS for evaluating the ‘tested’ job in nixos/release-small.nix from 1.33 GiB to 0.80 GiB, and runtime by about 8%.
2014-10-09	Typo	Eelco Dolstra	1	-1/+1

2014-10-05	Get rid of some unnecessary ExprConcatStrings nodes in dynamic attrs	Eelco Dolstra	3	-25/+18
	This gives a ~18% speedup in NixOS evaluation (after converting most calls to hasAttr/getAttr to dynamic attrs).
2014-10-05	Show total allocations	Eelco Dolstra	1	-8/+10

2014-10-04	Add primop ‘catAttrs’	Eelco Dolstra	1	-0/+30

2014-10-04	Tweak	Eelco Dolstra	1	-1/+1

2014-10-03	Remove some duplicate code	Eelco Dolstra	4	-21/+22

2014-10-03	Don't recompile the same regex over and over	Eelco Dolstra	2	-3/+8

2014-10-03	nix-env: Add regular expression support in selectors	Eelco Dolstra	3	-1/+60
	So you can now do things like: $ nix-env -qa '.zip.' $ nix-env -qa '.(firefox\|chromium).'
2014-10-03	createDirs(): Handle ‘path’ being a symlink	Eelco Dolstra	1	-0/+3
	In particular, this fixes "nix-build -o /tmp/result" on Mac OS X (where /tmp is a symlink).
2014-10-01	printValue(): Don't print <CYCLE> for repeated values	Eelco Dolstra	1	-7/+9

2014-09-30	Support control characters in JSON output	Eelco Dolstra	2	-0/+8

2014-09-26	printMissing(): Print derivations in approximate build order	Eelco Dolstra	1	-6/+9

2014-09-25	nix-daemon: Close unnecessary fd	Eelco Dolstra	1	-0/+2

2014-09-24	Bindings: Remove copy constructor	Eelco Dolstra	1	-2/+3

	nix-install-package --set
2014-09-23	Add missing static	Eelco Dolstra	1	-2/+2

2014-09-22	Don't evaluate inside a "throw"	Eelco Dolstra	1	-3/+4
	Workaround for https://gcc.gnu.org/bugzilla/show_bug.cgi?id=41174. This caused hydra-eval-jobs to ignore SIGINT.
