beorn7	4b574e8a61	Switch chunk encoding to type 2 where it was hardcoded type 1 before The chunk encoding was hardcoded there because it mostly doesn't matter what encoding is chosen in that test. Since type 1 is battle-hardened enough, I'm switching to type 2 here so that we can catch unexpected problems as a byproduct. My expectation is that the chunk encoding doesn't matter anyway, as said, but then "unexpected problems" contains the word "unexpected".	9 years ago
beorn7	c72979e3ed	Remove a redundancy from Gorilla-style chunks So far, the last sample in a chunk was saved twice. That's required for adding more samples as we need to know the last sample added to add more samples without iterating through the whole chunk. However, once the last sample was added to the chunk before it's full, there is no need to save it twice. Thus, the very last sample added to a chunk can _only_ be saved in the header fields for the last sample. The chunk has to be identifiable as closed, then. This information has been added to the flags byte.	9 years ago
beorn7	b6dbb826ae	Improve fuzz testing and fix a bug exposed This improves fuzz testing in two ways: (1) More realistic time stamps. So far, the most common case in practice was very rare in the test: Completely regular increases of the timestamp. (2) Verify samples by scanning through the whole relevant section of the series. For Gorilla-like chunks, this showed two things: (1) With more regularly increasing time stamps, BenchmarkFuzz is essentially as fast as with the traditional chunks: ``` BenchmarkFuzzChunkType0-8 2 972514684 ns/op 83426196 B/op 2500044 allocs/op BenchmarkFuzzChunkType1-8 2 971478001 ns/op 82874660 B/op 2512364 allocs/op BenchmarkFuzzChunkType2-8 2 999339453 ns/op 76670636 B/op 2366116 allocs/op ``` (2) There was a bug related to when and how the chunk footer is overwritten to make use for the last sample. This wasn't exposed by random access as the last sample of a chunk is retrieved from the values in the header in that case.	9 years ago

beorn7	8cdced3850	Implement Gorilla-inspired chunk encoding This is not a verbatim implementation of the Gorilla encoding. First of all, it could not, even if we wanted, because Prometheus has a different chunking model (constant size, not constant time). Second, this adds a number of changes that improve the encoding in general or at least for the specific use case of Prometheus (and are partially only possible in the context of Prometheus). See comments in the code for details.	9 years ago

beorn7	47e3c90f9b	Clean up error propagation Only return an error where callers are doing something with it except simply logging and ignoring. All the errors touched in this commit flag the storage as dirty anyway, and that fact is logged anyway. So most of what is being removed here is just log spam. As discussed earlier, the class of errors that flags the storage as dirty signals fundamental corruption, no even bubbling up a one-time warning to the user (e.g. about incomplete results) isn't helping much because _anything_ happening in the storage has to be doubted from that point on (and in fact retroactively into the past, too). Flagging the storage dirty, and alerting on it (plus marking the state in the web UI) is the only way I can see right now. As a byproduct, I cleaned up the setDirty method a bit and improved the logged errors.	9 years ago
