c1761cab49 Trigger ItemFinished when temp file creation fails instead of failing silently 2015-06-03 16:28:31 +02:00

90a1d99785 Reuse a timer instead of allocating a new one in subscription.Poll
This is surprisingly memory expensive when Poll gets called a lot, such
as when syncing lots of small files generating itemstarted/itemfinished
events. It's line number three in this heap profile on the
TestBenchmarkManyFiles test:

	jb@syno:~/src/github.com/syncthing/syncthing/test (master) $ go tool pprof ../bin/syncthing heap-13194.pprof
	Entering interactive mode (type "help" for commands)
	(pprof) top
	80.91MB of 83.05MB total (97.42%)
	Dropped 1024 nodes (cum <= 0.42MB)
	Showing top 10 nodes out of 85 (cum >= 1.75MB)
	      flat  flat%   sum%        cum   cum%
	      32MB 38.53% 38.53%    32.01MB 38.54%  github.com/syndtr/goleveldb/leveldb/memdb.New
	   22.16MB 26.68% 65.21%    22.16MB 26.68%  github.com/syndtr/goleveldb/leveldb/util.(*BufferPool).Get
	   13.02MB 15.68% 80.89%    13.02MB 15.68%  time.NewTimer
	    6.94MB  8.35% 89.24%     6.94MB  8.35%  github.com/syndtr/goleveldb/leveldb/memdb.(*DB).Put
	    3.18MB  3.82% 93.06%     3.18MB  3.82%  github.com/calmh/xdr.(*Reader).ReadBytesMaxInto

With this change the allocation is removed entirely.

7bf55dd14f events.Subscription.Poll does not seem to require locking
This is a large source of output from the new lock logging, and it
doesn't seem to accomplish anything useful that I can see. Running
integration with the race detector to make sure...

2c8b627008 Integer type policy
Integers are for numbers, enabling arithmetic like subtractions and for
loops without getting shot in the foot. Unsigneds are for bitfields.

- "int" for numbers that will always be laughably smaller than four
  billion, and where we don't care about the serialization format.

- "int32" for numbers that will always be laughably smaller than four
  billion, and will be serialized to four bytes.

- "int64" for numbers that may approach four billion or will be
  serialized to eight bytes.

- "uint32" and "uint64" for bitfields, depending on required number of
  bits and serialization format. Likewise "uint8" and "uint16", although
  rare in this project since they don't exist in XDR.

- "int8", "int16" and plain "uint" are almost never useful.

1a2a27b988 Minor fixes.
- Bug fix - use .Errorf() instead of .Error():
  Before this change, an error message for failed tests in files/set_test.go
  wrongly tried to use format strings in a call to .Error()

- Change event constants to be of type EventType rather than untyped integers.

- Slightly relax the locking for registry cache lookups:
  For read access to Discover.registry we only need to take a read lock.

- Some cosmetic fixes.
