2017-01-19Kill builds when we get EOF on the log FDEelco Dolstra
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.
2017-01-17Handle SIGINT etc. via a sigwait() signal handler threadEelco Dolstra
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.
2016-11-26Revert "Get rid of unicode quotes (#1140)"Eelco Dolstra
This reverts commit f78126bfd6b6c8477fcdbc09b2f98772dbe9a1e7. There really is no need for such a massive change...

This variable has no reason to exist, given $NIX_STATE_DIR.

2016-04-25Show the log tail when a build failsEelco Dolstra
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.
2016-04-25Remove --print-build-traceEelco Dolstra
This was added to support Hydra, but Hydra no longer uses it.
2016-04-25Improved logging abstractionEelco Dolstra
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.
2016-03-29Improve SIGINT handling in multi-threaded programsEelco Dolstra
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.
2016-03-29Re-enable sync_with_stdioEelco Dolstra
Otherwise writing to std::cerr is not thread-safe (in particular, lines will be randomly duplicated).

OpenSSL can randomly segfault unless we register a callback function to do locking. https://www.openssl.org/docs/manmaster/crypto/threads.html

2016-02-04StoreAPI -> StoreEelco Dolstra
Calling a class an API is a bit redundant...
2016-02-04Eliminate the "store" global variableEelco Dolstra
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.)

2014-12-05Use posix_spawn to run the pagerEelco Dolstra
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...)
