2014-01-06 Disable FreeBSD tests for nowEelco Dolstra1-5/+5
The FreeBSD machines in the build farm are currently unreachable.
2014-01-06 Disable the tail call testEelco Dolstra1-0/+0
On i686-linux, GCC stubbornly refuses to do tail-call optimisation. Don't know why. http://hydra.nixos.org/build/7300170
2013-12-30 nix-shell --pure: Don't clear IN_NIX_SHELLShea Levy1-1/+1

2013-12-20 Revert "Scan /proc/<pid>/cmdline for GC roots"Eelco Dolstra1-8/+4
This reverts commit 194e3374b89b8b2dec6296923877304bdb5c6ae2. Checking the command line for GC roots means that $ nix-store --delete $path will fail because $path is now a root because it's mentioned on the command line.

2013-12-20 perl: Call loadConfFile() in doInit to avoid screwing sqlite journal mode.Petr Rockai1-0/+2
If the database is opened through perl bindings (and even though nix.conf has use-sqlite-wal set to false), the database is automatically converted into WAL mode. This makes the next nix process to access the database convert it back to "truncate". If the database is still open at the time in wal mode by the perl program, this fails and crashes the nix doing the wal -> truncate conversion.
2013-12-20 nix-env --set-flag: Barf if a selector doesn't match any installed packageEelco Dolstra1-5/+13
Fixes #184.
2013-12-20 Scan /proc/<pid>/cmdline for GC rootsEelco Dolstra1-4/+8
2013-12-20 nix-shell: Don't warn about the lack of a GC rootEelco Dolstra2-1/+6
2013-12-20 nix-shell: Set $IN_NIX_SHELL before evaluationEelco Dolstra1-2/+2
This has some hacky applications.
2013-12-20 nix-shell: Handle --option correctlyEelco Dolstra2-3/+7
Fixes #181.
2013-12-17 nix-shell --pure: Keep $TERMEelco Dolstra1-1/+1
2013-12-10 Bump language version for new storePath featureShea Levy1-1/+1
This will allow e.g. channel expressions to use builtins.storePath IFF it is safe to do so without knowing if the path is valid yet. Signed-off-by: Shea Levy <shea@shealevy.com>
2013-12-10 builtins.storePath: Try to substitute the path if it is not yet validShea Levy1-2/+2
Signed-off-by: Shea Levy <shea@shealevy.com>
2013-12-10 Garbage collector: Release locks on temporary root filesEelco Dolstra1-0/+1
This allows processes waiting for such locks to proceed during the trash deletion phase of the garbage collector.
2013-12-05 Print a trace message if a build fails due to the platform being unknownEelco Dolstra1-1/+4
2013-11-22 Include <cstring> for memsetEelco Dolstra1-0/+1
This should fix building on Illumos.
2013-11-19 Bump version numberEelco Dolstra1-1/+1

2013-11-19 Drop support for user environment manifests in ATerm formatEelco Dolstra1-112/+1
2013-11-19 nix-env -q: Add a --json flagEelco Dolstra1-8/+45
2013-11-19 Refactor JSON outputEelco Dolstra2-13/+56
2013-11-19 Add a toJSON primopEelco Dolstra10-24/+179
2013-11-18 Add a primop unsafeGetAttrPos to return the position of an attributeEelco Dolstra6-6/+44
2013-11-18 Add a symbol __curPos that expands to the current source locationEelco Dolstra7-2/+43
I.e. an attribute set { file = <string>; line = <int>; column = <int>; }.
2013-11-18 Support quoted attribute names in -AEelco Dolstra3-14/+38
This is requires if you have attribute names with dots in them. So you can now say: $ nix-instantiate '<nixos>' -A 'config.systemd.units."postgresql.service".text' --eval-only Fixes #151.
2013-11-14 Remove nix-setuid-helperEelco Dolstra13-526/+50
AFAIK, nobody uses it, it's not maintained, and it has no tests.
2013-11-12 Make function calls show up in stack traces againEelco Dolstra4-26/+35
Note that adding --show-trace prevents functions calls from being tail-recursive, so an expression that evaluates without --show-trace may fail with a stack overflow if --show-trace is given.
2013-11-12 Add a test to check that tail calls run in bounded stack spaceEelco Dolstra2-0/+4
2013-11-12 Make function calls tail-recursiveEelco Dolstra4-40/+65
2013-11-12 Make ifs and asserts tail-recursiveEelco Dolstra2-4/+11
The local Value object prevented g++ from making a tail call. Not clear why. In any case, not using a temporary makes g++ do the tail call.
2013-11-12 Get rid of an intermediary on the stackEelco Dolstra2-13/+17
2013-10-28 Fix building without a garbage collectorEelco Dolstra1-5/+5
http://hydra.nixos.org/build/6695350
2013-10-28 Fix a segfault in genericClosureEelco Dolstra1-16/+25
It kept temporary data in STL containers that were not scanned by Boehm GC, so Nix programs using genericClosure could randomly crash if the garbage collector kicked in at a bad time. Also make it a bit more efficient by copying points to values rather than values.
2013-10-28 Drop Cygwin and Solaris buildsEelco Dolstra1-1/+1

2013-10-24 Fix segfault on DarwinEelco Dolstra2-0/+2
Ever since SQLite in Nixpkgs was updated to 3.8.0.2, Nix has randomly segfaulted on Darwin: http://hydra.nixos.org/build/6175515 http://hydra.nixos.org/build/6611038 It turns out that this is because the binary cache substituter somehow ends up loading two versions of SQLite: the one in Nixpkgs and the other from /usr/lib/libsqlite3.dylib. It's not exactly clear why the latter is loaded, but it appears to be because WWW::Curl indirectly loads /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation, which in turn seems to load /usr/lib/libsqlite3.dylib. This leads to a segfault when Perl exits: #0 0x00000001010375f4 in sqlite3_finalize () #1 0x000000010125806e in sqlite_st_destroy () #2 0x000000010124bc30 in XS_DBD__SQLite__st_DESTROY () #3 0x00000001001c8155 in XS_DBI_dispatch () ... #14 0x0000000100023224 in perl_destruct () #15 0x0000000100000d6a in main () ... The workaround is to explicitly load DBD::SQLite before WWW::Curl.
2013-10-24 Rename "attribute sets" to "sets"Eelco Dolstra13-160/+152
We don't have any other kind of sets so calling them attribute sets is unnecessarily verbose.
2013-10-24 Manual: Fix broken URLsEelco Dolstra2-3/+3
Fixes #172.
2013-10-24 Add rpm_fedora19i386 to the release-critical buildsEelco Dolstra1-1/+1
2013-10-24 Remove unnecessary call to forceStringNoCtxEelco Dolstra1-1/+1
2013-10-24 Document typeOfEelco Dolstra1-0/+13
2013-10-24 Add a test of the type primopsEelco Dolstra2-0/+24
2013-10-24 Add a typeOf primopEelco Dolstra1-3/+28
We already have some primops for determining the type of a value, such as isString, but they're incomplete: for instance, there is no isPath. Rather than adding more isBla functions, the generic typeOf function returns a string representing the type of the argument (e.g. "int").
2013-10-24 Document NIX_SHOW_STATS and NIX_COUNT_CALLSEelco Dolstra1-0/+18
