2020-01-05 Move #includeEelco Dolstra3-2/+3
(cherry picked from commit 8beedd44861d1fe7208609ee8d231ca1c02dedf6) (cherry picked from commit 0678e4d56a839f940af8aa70059ced48b393e817)
2020-01-05 Hide FunctionCallTrace constructor/destructorEelco Dolstra3-15/+20
This prevents them from being inlined. On gcc 9, this reduces the stack size needed for nix-instantiate '<nixpkgs>' -A texlive.combined.scheme-full --dry-run from 12.9 MiB to 4.8 MiB. (cherry picked from commit cb90e382b5b6e177ea902b3909fd1897643ae3cd)
2020-01-05 function-trace: always show the tracezimbatm1-2/+2
If the user invokes nix with --trace-function-calls it means that they want to see the trace. (cherry picked from commit 619cc4af855fab7b0400586a4fd40745b23e72ad)
2020-01-04 Ensure enough space in attrset bindings when using both __overrides and ↵Puck Meerburg1-1/+1
dynamic attributes (cherry picked from commit cd55f91ad2075d5ebb506950dfbc4161cab22db5)
2020-01-04 builtins.toJSON: fix __toString usageRobin Gloster3-7/+27
(cherry picked from commit e583df52800b4baa1564b027fe3b83a21756c2cc)
2020-01-04 Move tmpDirInSandbox to initTmpDirMatthew Bauer1-8/+8
(cherry picked from commit 96c84937c49435525d0733437aa88902b2c8caf6)
2020-01-04 Fix sandbox fallback settingsMatthew Bauer1-26/+34
The tmpDirInSandbox is different when in sandboxed vs. non-sandboxed. Since we don’t know ahead of time here whether sandboxing is enabled, we need to reset all of the env vars we’ve set previously. This fixes the issue encountered in https://github.com/NixOS/nixpkgs/issues/70856. (cherry picked from commit 499b0388759db0f9f385da402a4bba551268aa99)
2020-01-04 ssh-ng: Don't set CPU affinity on the remoteEelco Dolstra3-1/+9
Fixes #3138. (cherry picked from commit 906d56a96b442d4dd8f924c1ce0d1eec0e214af3)
2020-01-04 SourceExprCommand::getSourceExpr(): Allocate more spaceEelco Dolstra1-1/+1
Fixes #3140. (cherry picked from commit 389a2cebed7cd72bda524ece0a56af2888cd80b6)
2020-01-04 include netinet/in.h in src/nix/main.ccng01-0/+1
Fixes #3186 (cherry picked from commit b811bd2172bc9796f42b87996f455d4e5e4382ba)
2020-01-04 Fix progress bar when nix-prefetch-url is piped.Harald van Dijk2-2/+2
The intent of the code was that if the window size cannot be determined, it would be treated as having the maximum possible size. Because of a missing assignment, it was actually treated as having a width of 0. The reason the width could not be determined was because it was obtained from stdout, not stderr, even though the printing was done to stderr. This commit addresses both issues. (cherry picked from commit c935ad3f025d5c3d8026711a1eb50b2917b61d59)
2020-01-04 Fix typosBrian Wignall2-2/+2
(cherry picked from commit 8737980e75bf14cae278f596ac26577bec94b3f9)
2020-01-04 EvalState::callFunction(): Make FunctionCallTrace use less stack spaceEelco Dolstra1-4/+3
The FunctionCallTrace object consumes a few hundred bytes of stack space, even when tracing is disabled. This was causing stack overflows: $ nix-instantiate '<nixpkgs> -A texlive.combined.scheme-full --dry-run error: stack overflow (possible infinite recursion) This is with the default stack size of 8 MiB. Putting the object on the heap reduces stack usage to < 5 MiB. (cherry picked from commit 98ef11677c43db9aa669768d9f0cbec704e8831c)
2019-10-10 nix verify: Fix uninitialized variableEelco Dolstra1-2/+2

2019-10-10 nix-env: Ignore failures creating ~/.nix-profile and ~/.nix-defexprEelco Dolstra1-14/+20
https://hydra.nixos.org/build/102803093 (cherry picked from commit c3aaf3b8da1a925c569389f13a861816a781a3c8)

2019-10-10 nix-env: Create ~/.nix-defexpr automaticallyEelco Dolstra1-7/+12

2019-10-09 Force per-user group to a known valueEelco Dolstra1-1/+1
(cherry picked from commit 20eec802ff11dd2b152715cd5c81b756d318219d)
2019-10-09 Go back to 755 permission on per-user directoriesEelco Dolstra1-1/+1
700 is pointless since the store is world-readable anyway. And per-user/root/channels must be world-readable. (cherry picked from commit d7bae5680fc26303acb9a9ee1a202f537841a624)
2019-10-09 Remove world-writability from per-user directoriesEelco Dolstra4-7/+31
'nix-daemon' now creates subdirectories for users when they first connect. Fixes #509 (CVE-2019-17365). Should also fix #3127. (cherry picked from commit 5a303093dcae1e5ce9212616ef18f2ca51020b0d)
2019-10-09 Filter ANSI escape sequences in -L outputEelco Dolstra1-1/+1
Otherwise, builds like NixOS VM tests may leave the terminal in a weird state and do resets. (cherry picked from commit 4331eeb13d241dfe2d2e6a01c53915c556cac94f)
2019-10-09 Disable OpenSSL lock callback on OpenSSL >= 1.1.1Eelco Dolstra1-0/+4

2019-10-09 Handle empty sandbox_shellMatthew Bauer1-1/+4
Previously, SANDBOX_SHELL was set to empty when unavailable. This caused issues when actually generating the sandbox. Instead, just set SANDBOX_SHELL when --with-sandbox-shell= is non-empty. Alternative implementation to https://github.com/NixOS/nix/pull/3038. (cherry picked from commit 199e888785bd23073e44e56f6c74b95dc7c10ffa)
2019-10-09 nix search: Don't quietly ignore errorsEelco Dolstra1-0/+1

2019-10-09 getSourceExpr(): Handle channelsEelco Dolstra1-15/+16
Fixes #1892. Fixes #1865. Fixes #3119. (cherry picked from commit e6e61f0a54dac0174df996e93fcfedcac7769ab4)
2019-09-03 Support allowSubstitutes attribute in structured attribute derivationsEelco Dolstra6-10/+11
Hopefully fixes #3081 (didn't test).
2019-09-03 Add some noexceptsEelco Dolstra11-18/+19
This is to assert that callback functions should never throw (since the context in which they're called may not be able to handle the exception).
2019-09-03 Ensure that Callback is called only onceEelco Dolstra5-17/+36
Also, make Callback movable but uncopyable.

2019-08-28 Set maximum name length in NixMatthew Bauer1-0/+4
Previously we allowed any length of name for Nix derivations. This is bad because different file systems have different max lengths. To make things predictable, I have picked a max. This was done by trying to build this derivation: derivation { name = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"; builder = "/no-such-path"; system = "x86_64-linux"; } Take off one a and it will not lead to file name too long. That ends up being 212 a’s. An even smaller max could be picked if we want to support more file systems. Working backwards, this is why: aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa-${name}.drv.chroot > 255 - 32 - 1 - 4 - 7 = 211
2019-08-28 Don't send certain setting overrides to the daemonEelco Dolstra1-0/+7
These are already handled separately. This fixes warnings like warning: ignoring the user-specified setting 'max-jobs', because it is a restricted setting and you are not a trusted user when using the -j flag.

2019-08-16 nix-store: fix out of sync protocolzimbatm1-2/+10
If a NAR is already in the store, addToStore doesn't read the source which makes the protocol go out of sync. This happens for example when two client try to nix-copy-closure the same derivation at the same time.
2019-08-16 libutil: add SizedSourcezimbatm1-0/+30
Introduce the SizeSource which allows to bound how much data is being read from a source. It also contains a drainAll() function to discard the rest of the source, useful to keep the nix protocol in sync.

Make curl's low speed limit configurable via stalled-download-timeout. Before, this limit was five minutes without receiving a single byte. This is much too long as if the remote end may not have even acknowledged the HTTP request.
