2015-01-02	libutil: Limit readLink() error to only overflows.	aszlig	1	-2/+2
	Let's not just improve the error message itself, but also the behaviour to actually work around the ntfs-3g symlink bug. If the readlink() call returns a smaller size than the stat() call, this really isn't a problem even if the symlink target really has changed between the calls. So if stat() reports the size for the absolute path, it's most likely that the relative path is smaller and thus it should also work for file system bugs as mentioned in 93002d69fc58c2b71e2dfad202139230c630c53a.

2015-01-02	libutil: Improve errmsg on readLink size mismatch.	aszlig	1	-1/+5
	A message like "error: reading symbolic link `...' : Success" really is quite confusing, so let's not indicate "success" but rather point out the real issue. We could also limit the check of this to just check for non-negative values, but this would introduce a race condition between stat() and readlink() if the link target changes between those two calls, thus leading to a buffer overflow vulnerability. Reported by @Ericson2314 on IRC. Happened due to a possible ntfs-3g bug where a relative symlink returned the absolute path (st_)size in stat() while readlink() returned the relative size.

2014-12-12	Remove chatty message	Eelco Dolstra	1	-2/+0
	This broke building with "-vv", because the builder is not allowed to write to stderr at this point.

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 ./.)

2014-11-24	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

2014-11-15	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.
