2017-01-19 Kill builds when we get EOF on the log FDEelco Dolstra1-1/+1
This closes a long-time bug that allowed builds to hang Nix indefinitely (regardless of timeouts) simply by doing exec > /dev/null 2>&1; while true; do true; done Now, on EOF, we just send SIGKILL to the child to make sure it's really gone.
2017-01-17 Handle SIGINT etc. via a sigwait() signal handler threadEelco Dolstra1-17/+3
This allows other threads to install callbacks that run in a regular, non-signal context. In particular, we can use this to signal the downloader thread to quit. Closes #1183.
2016-11-26 Revert "Get rid of unicode quotes (#1140)"Eelco Dolstra2-11/+11
This reverts commit f78126bfd6b6c8477fcdbc09b2f98772dbe9a1e7. There really is no need for such a massive change...
2016-11-25 Get rid of unicode quotes (#1140)Guillaume Maudoux2-11/+11
2016-10-12 Shut up some warningsEelco Dolstra1-1/+1
2016-09-21 printMsg(lvlError, ...) -> printError(...) etc.Eelco Dolstra1-11/+11
2016-08-10 Remove $NIX_DB_DIREelco Dolstra1-1/+0
This variable has no reason to exist, given $NIX_STATE_DIR.
2016-07-11 Modernize AutoCloseFDShea Levy1-2/+2
2016-04-25 Show the log tail when a build failsEelco Dolstra1-1/+1
If --no-build-output is given (which will become the default for the "nix" command at least), show the last 10 lines of the build output if the build fails.
2016-04-25 Remove --print-build-traceEelco Dolstra1-3/+0
This was added to support Hydra, but Hydra no longer uses it.
2016-04-25 Improved logging abstractionEelco Dolstra2-11/+1
This also gets rid of --log-type, since the nested log type isn't useful in a multi-threaded situation, and nobody cares about the "pretty" log type.
2016-03-29 Improve SIGINT handling in multi-threaded programsEelco Dolstra1-9/+2
The flag remembering whether an Interrupted exception was thrown is now thread-local. Thus, all threads will (eventually) throw Interrupted. Previously, one thread would throw Interrupted, and then the other threads wouldn't see that they were supposed to quit.
2016-03-29 Re-enable sync_with_stdioEelco Dolstra1-3/+0
Otherwise writing to std::cerr is not thread-safe (in particular, lines will be randomly duplicated).

2016-02-22 Make OpenSSL usage thread-safeEelco Dolstra3-4/+26
OpenSSL can randomly segfault unless we register a callback function to do locking. https://www.openssl.org/docs/manmaster/crypto/threads.html

2016-02-04 StoreAPI -> StoreEelco Dolstra2-5/+5
Calling a class an API is a bit redundant...
2016-02-04 Eliminate the "store" global variableEelco Dolstra2-9/+8
Also, move a few free-standing functions into StoreAPI and Derivation. Also, introduce a non-nullable smart pointer, ref<T>, which is just a wrapper around std::shared_ptr ensuring that the pointer is never null. (For reference-counted values, this is better than passing a "T&", because the latter doesn't maintain the refcount. Usually, the caller will have a shared_ptr keeping the value alive, but that's not always the case, e.g., when passing a reference to a std::thread via std::bind.)

2015-07-23 --version: Print some config infoEelco Dolstra1-0/+14
Such as whether Nix is built with signed binary cache support, and the location of the configuration file.
2015-07-20 Support systemd log severity prefixesEelco Dolstra1-0/+4
This is mostly useful for hydra-queue-runner.

2014-12-10 Revert "Use posix_spawn to run the pager"Eelco Dolstra1-30/+8
This reverts commit d34d2b2bbf784c0bb420a50905af25e02c6e4989.

2014-12-05 Use posix_spawn to run the pagerEelco Dolstra1-8/+30
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...)

So now nix-instantiate --eval -E '{x}: x' --argstr x -xyzzy correctly prints "-xyzzy", rather than giving an error. Issue NixOS/hydra#176.
