Eelco Dolstra	e4f5156c41	Build against nix-master ... (cherry picked from commit e7f2139e25)	2020-02-20 10:24:04 +01:00
Hamish Mackenzie	c40c887e50	Fixes for macOS ... Building on macOS with the latest nixpkgs master and NixOS/nixpkgs#77147 fails. It seems some `std::experimental` (optional) for instance are not available as `experimental`, but are in `std`. Also `toJSON` is missing for `atomic< unsigned long long >`.	2020-01-07 12:38:06 +13:00
Eelco Dolstra	4e27796eba	Allow setting GC_INITIAL_HEAP_SIZE for hydra-eval-jobs ... This cannot be done in the hydra-evaluator systemd unit, since then every other Nix process (e.g. hydra-evaluator and nix-prefetch-*) will also allocate the specified heap size, probably leading to OOM.	2018-05-16 14:14:53 +02:00
Eelco Dolstra	dc5e0b120a	Fix a race that can cause hydra-queue-runner to ignore newly added builds ... As @dtzWill discovered, with the concurrent hydra-evaluator, there can be multiple active transactions adding builds to the database. As a result, builds can become visible in a non-monotonically increasing order, breaking the queue monitor's assumption that build IDs only go up. The fix is to have hydra-eval-jobset provide the lowest build ID it just added in the builds_added notification, and have the queue monitor check from there. Fixes #496.	2017-07-21 14:34:48 +02:00
Eelco Dolstra	e0b2921ff2	Concurrent hydra-evaluator ... This rewrites the top-level loop of hydra-evaluator in C++. The Perl stuff is moved into hydra-eval-jobset. (Rewriting the entire evaluator would be nice but is a bit too much work.) The new version has some advantages: * It can run multiple jobset evaluations in parallel. * It uses PostgreSQL notifications so it doesn't have to poll the database. So if a jobset is triggered via the web interface or from a GitHub / Bitbucket webhook, evaluation of the jobset will start almost instantaneously (assuming the evaluator is not at its concurrency limit). * It imposes a timeout on evaluations. So if e.g. hydra-eval-jobset hangs connecting to a Mercurial server, it will eventually be killed.	2016-10-14 14:22:12 +02:00
