Eelco Dolstra 524ee295e0 Fix sending notifications in the successful case 2015-06-23 02:13:06 +02:00
Eelco Dolstra 4db7c51b5c Rate-limit the number of threads copying closures at the same time 
Having a hundred threads doing I/O at the same time is bad on magnetic
disks because of the excessive disk seeks. So allow only 4 threads to
copy closures in parallel.

Eelco Dolstra a317d24b29 hydra-queue-runner: Send build notifications 
Since our notification plugins are written in Perl, sending
notification from C++ requires a small Perl helper named
‘hydra-notify’.

Eelco Dolstra d744362e4a hydra-queue-runner: Fix segfault sorting machines by load 
While sorting machines by load, the load of a machine
(machine->currentJobs) can be changed by other threads. If that
happens, the comparator is no longer a proper ordering, in which case
std::sort() can segfault. So we now make a copy of currentJobs before
sorting.

Eelco Dolstra 9cdbff2fdf Handle concurrent finishing of the same build 
There is a slight possibility that the queue monitor and a builder
thread simultaneously decide to mark a build as finished. That's fine,
as long as we ensure the DB update is idempotent (as ensured by doing
"update Builds set finished = 1 ... where finished = 0").

Eelco Dolstra b1a75c7f63 getQueuedBuilds(): Handle dependent builds first 
If a build A depends on a derivation that is the top-level derivation
of some build B, then we should process B before A (meaning we
shouldn't make the derivation runnable before B has been
added). Otherwise, the derivation will be "accounted" to A rather than
B (so the build step will show up in the wrong build).

Eelco Dolstra b91a616520 Automatically retry aborted builds 
Aborted builds are now put back on the runnable queue and retried
after a certain time interval (currently 60 seconds for the first
retry, then tripled on each subsequent retry).
