nix search: tests and fix #1893 and part of #1892

2018-03-09 Fix double free in Store::queryPathInfo()Eelco Dolstra1-4/+4
It was holding on to a Value* (i.e. a std::shared_ptr<ValidPathInfo>*) outside of the pathInfoCache lock, so the std::shared_ptr could be destroyed between the release of the lock and the decrement of the std::shared_ptr refcount. This can happen if more than 'path-info-cache-size' paths are added in the meantime, *or* if clearPathInfoCache() is called. The hydra-queue-runner queue monitor thread periodically calls the later, so is likely to trigger a crash. Fixes https://github.com/NixOS/hydra/issues/542.
2018-03-09 Modified MakeBinOp to no longer produce its name using concatenation and "##".Tim Engler1-11/+11
Doing so prevents emacs tags from working, as well as makes the code extremely confusing for a newbie. In the prior state, if someone wants to find the definition of "ExprApp" for example, a grep through the code reveals nothing. Since the definition could be hiding in numerous ".h" files, it's really difficult to find. This personally took me several hours to figure out.
2018-03-07 Fix #1957Eelco Dolstra1-1/+1
2018-03-07 Merge pull request #1955 from dtzWill/fix/rand-randomEelco Dolstra3-3/+3
rand() -> random(), since we use srandom().
2018-03-06 rand() -> random(), since we use srandom().Will Dietz3-3/+3
rand() requires we call srand() instead, but might as well use random().
2018-03-06 logging: Don't throw from Activity destructorWill Dietz2-2/+9
Move definition of destructor to logging.cc for access to util.hh's ignoreException.
2018-03-05 ssh-ng: Don't forward options to the daemon.Shea Levy2-1/+12
This can be iterated on and currently leaves out settings we know we want to forward, but it fixes #1713 and fixes #1935 and isn't fundamentally broken like the status quo. Future changes are suggested in a comment.

2018-02-28 Actually fix nixDataDir in non-canonical pathShea Levy2-2/+2
2018-02-26 libexpr: Fix prim_replaceStrings() to work on an empty source stringTuomas Tynkkynen1-3/+14
Otherwise, running e.g. nix-instantiate --eval -E --strict 'builtins.replaceStrings [""] ["X"] "abc"' would just hang in an infinite loop. Found by afl-fuzz. First attempt of this was reverted in e2d71bd1862cdda because it caused another infinite loop, which is fixed now and a test added.
2018-02-26 nix run: Fix segfault on macOSEelco Dolstra3-3/+11
Note that clearenv() is not available on macOS. Fixes #1907.
2018-02-25 nix search: explicitly handle empty search string, fixes #1893Will Dietz1-0/+5
This is important since this is given as an example. Other patterns containing "empty search string" will still be handled differently on different platforms ("asdf|") but that's less of an issue.
2018-02-25 nix search: fix bug where we wrote to cache when shouldn't, breakingWill Dietz1-1/+1
This is exposed by the tests added previously, and resolves the error reported in #1892: "expected JSON value".
2018-02-23 Fix downloadCached() with a chroot storeEelco Dolstra1-2/+2
E.g. nix run --store ~/my-nix -f channel:nixos-17.03 hello -c hello This problem was mentioned in #1897.
2018-02-22 Merge branch 'data-dir-non-canon' of https://github.com/shlevy/nixEelco Dolstra1-1/+1
2018-02-22 Revert "Enable sandbox builds on Linux by default"Eelco Dolstra1-7/+1
This reverts commit ddc58e789636e1b94149c342575d92583251fbf6. https://hydra.nixos.org/eval/1435322
2018-02-22 Fix restricted mode when installing in non-canonical data dirShea Levy1-1/+1
2018-02-22 Enable sandbox builds on Linux by defaultEelco Dolstra1-1/+7
The overhead of sandbox builds is a problem on NixOS (since building a NixOS configuration involves a lot of small derivations) but not for typical non-NixOS use cases. So outside of NixOS we can enable it. Issue #179.

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.

2018-02-21 nix-copy: fix examplesJörg Thalheim1-3/+3
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 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 Fix incorrect (and unnecessary) format stringEelco Dolstra1-3/+3
https://hydra.nixos.org/eval/1434547#tabs-now-fail
2018-02-19 Update release notesEelco Dolstra2-0/+24

2018-02-19 Merge pull request #1882 from shlevy/no-seccomp-no-filterSyscallsEelco Dolstra1-2/+7
Don't silently succeed seccomp setup when !HAVE_SECCOMP.

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.

configure.ac: check if lzma has MT support, fix deb build/etc.
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: Optimize prim_derivationStrict by using more symbol comparisonsTuomas Tynkkynen3-10/+15
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.
2018-02-15 Merge pull request #1873 from matthewbauer/fix-manpathEelco Dolstra4-0/+6
Set MANPATH in case man path isn’t set correctly.
