2018-02-21 Manual: Update chapter on remote buildsEelco Dolstra1-0/+35
Alos add a command "nix ping-store" to make it easier to see if Nix can connect to a remote builder (e.g. 'nix ping-store --store ssh://mac').
2018-02-21 Revert "libexpr: Fix prim_replaceStrings() to work on an empty source string"Eelco Dolstra1-8/+3
This reverts commit 4ea9707591beceacf9988b3c185faf50da238403. It causes an infinite loop in Nixpkgs evaluation, e.g. "nix-instantiate -A hello" hung. PR #1886.

maybe a left-over from nix-store -r ?
2018-02-19 libutil: Fix invalid assert on decoding base64 hashesTuomas Tynkkynen1-1/+2
The assertion is broken because there is no one-to-one mapping from length of a base64 string to the length of the output. E.g. "1q69lz7Empb06nzfkj651413n9icx0njmyr3xzq1j9q=" results in a 32-byte output. "1q69lz7Empb06nzfkj651413n9icx0njmyr3xzq1j9qy" results in a 33-byte output. To reproduce, evaluate: builtins.derivationStrict { name = "0"; builder = "0"; system = "0"; outputHashAlgo = "sha256"; outputHash = "1q69lz7Empb06nzfkj651413n9icx0njmyr3xzq1j9qy"; } Found by afl-fuzz.
2018-02-19 libexpr: Fix prim_replaceStrings() to work on an empty source stringTuomas Tynkkynen1-3/+8
Otherwise, running e.g. nix-instantiate --eval -E --strict 'builtins.replaceStrings [""] ["X"] "abc"' would just hang in an infinite loop. Found by afl-fuzz.
2018-02-19 libutil: Fix infinite loop in filterANSIEscapes on '\r'Tuomas Tynkkynen1-1/+1
E.g. nix-instantiate --eval -E 'abort "\r"' hangs. Found by afl-fuzz.
2018-02-19 libexpr: Don't create lots of temporary strings in Bindings::lexicographicOrderTuomas Tynkkynen1-1/+1
Avoids ~180,000 string temporaries created when evaluating a headless NixOS system.

2018-02-19 Don't silently succeed seccomp setup when !HAVE_SECCOMP.Shea Levy1-2/+7
Running Nix with build users without seccomp on Linux is dangerous, and administrators should very explicitly opt-in to it.

2018-02-18 configure: Add a flag to disable seccomp.Shea Levy2-2/+4
This is needed for new arches where libseccomp support doesn't exist yet. Fixes #1878.
2018-02-17 libexpr: Avoid an unnecessary string copy in prim_derivationStrictTuomas Tynkkynen1-1/+1
2018-02-17 libexpr: Remove unnecessary drvName assignment in prim_derivationStrictTuomas Tynkkynen1-6/+0
drvName is already assigned to the same value right at the start of the function.

2018-02-17 libexpr: Rely on Boehm returning zeroed memory in EvalState::allocEnv()Tuomas Tynkkynen2-5/+5
Boehm guarantees that memory returned by GC_malloc() is zeroed, so take advantage of that.
2018-02-17 libexpr: Optimize prim_attrNames a bitTuomas Tynkkynen1-2/+5
Instead of having lexicographicOrder() create a temporary sorted array of Attr*:s and copying attr names from that, copy the attr names first and then sort that.
2018-02-16 libexpr: Pre-reserve space in string in unescapeStr()Tuomas Tynkkynen1-3/+4
Avoids some malloc() traffic.

Set MANPATH in case man path isn’t set correctly.
2018-02-15 Set backup MANPATH in case man path isn’t set correctly.Matthew Bauer4-0/+6
Previously, this would fail at startup for non-NixOS installs: nix-env --help The fix for this is to just use "nixManDir" as the value for MANPATH when spawning "man". To test this, I’m using the following: $ nix-build release.nix -A build $ MANPATH= ./result/bin/nix-env --help Fixes #1627

Nix stats: flatten statistics
2018-02-12 Fix hang in build-remoteEelco Dolstra3-2/+4
2018-02-12 Fix 'deadlock: trying to re-acquire self-held lock'Eelco Dolstra4-22/+24
This was caused by derivations with 'allowSubstitutes = false'. Such derivations will be built locally. However, if there is another SubstitionGoal that has the output of the first derivation in its closure, then the path will be simultaneously built and substituted. There was a check to catch this situation (via pathIsLockedByMe()), but it no longer worked reliably because substitutions are now done in another thread. (Thus the comment 'It can't happen between here and the lockPaths() call below because we're not allowing multi-threading' was no longer valid.) The fix is to handle the path already being locked in both SubstitutionGoal and DerivationGoal.
