Goutham Veeramachaneni	45d3db4e9e	Use a *mapTombstoneReader instead of map ... We need to recalculate the sorted ref list everytime we make a Tombstones() call. This avoids that. Signed-off-by: Goutham Veeramachaneni <cs14btech11014@iith.ac.in>	8 years ago

Goutham Veeramachaneni	2fa647f50b	Fix missing postings in Merge and Intersect (#77) ... * Test for a previous implematation of Intersect Before we were moving the postings list everytime we create a new chained `intersectPostings`. That was causing some postings to be skipped. This test fails on the older version. Signed-off-by: Goutham Veeramachaneni <cs14btech11014@iith.ac.in> * Advance on Seek only when valid. Issue: Before in mergedPostings and others we advance everytime we `Seek`, which causes issues with `Intersect`. Take the case, where we have a mergedPostings = m merging, a: {10, 20, 30} and b: {15, 25, 35}. Everytime we `Seek`, we do a.Seek and b.Seek. Now if we Intersect m with {21, 22, 23, 30}, we would do Seek({21,22,23}) which would advance a and b beyond 30. Fix: Now we advance only when the seeking value is greater than the current value, as the definition specifies. Also, posting 0 will not be a valid posting and will be used to signal finished or un-initialized PostingsList.

Signed-off-by: Goutham Veeramachaneni <cs14btech11014@iith.ac.in> * Add comments to trivial tests. Signed-off-by: Goutham Veeramachaneni <cs14btech11014@iith.ac.in>	8 years ago

Brian Brazil	72443bddfc	Remove dead code.	8 years ago
Brian Brazil	bceb5c1b16	When checking for amended points, do it in terms of bits. ... NaN != NaN, so the previous code would incorrectly report it as changed. There's also plans to take advantage of the NaN payload, so look at the entire value.	8 years ago
Fabian Reinartz	778103b450	Add liecence file and headers	8 years ago
Fabian Reinartz	c73a397da2	Adjust maximum samples per chunk.	8 years ago
Goutham Veeramachaneni	a51b2666d7	Fix Panic When Accessing Uncut memorySeries ... When calling AddFast, we check the details of the head chunk of the referred memorySeries. But it could happen that there are no chunks in the series at all. Currently, we are deferring chunk creation to when we actually append samples, but we can be sure that there will be samples if the series is created. We will be consuming no extra memory by cutting a chunk when we create the series. Ref: #28 comment 2 Signed-off-by: Goutham Veeramachaneni <cs14btech11014@iith.ac.in>	8 years ago
Fabian Reinartz	10c7c9acbe	Adjust import names to new repository organisation	8 years ago
Fabian Reinartz	87d48bf9de	Merge branch 'master' of github.com:fabxc/tsdb	8 years ago
Fabian Reinartz	a52980e0a8	Add workaround for deadlocks ... This adds a workaround to avoid deadlocks for inconsistent write lock order across headBlocks. Things keep working if transactions only append data for the same timestamp, which is generally the case for Prometheus. Full behavior should be restored in a subsequent change.	8 years ago
Goutham Veeramachaneni	61f866bb94	Add Sample Back ... The compilation and tests are broken as head.go requires sample which has been moved to another package while moving BufferedSeriesIterator. Duplication seemed better compared to exposing sample from tsdbutil.	8 years ago
Fabian Reinartz	3be4ef94ce	Move BufferedSeriesIterator in own package ... This functionality is useful for a lot of clients but not relevant to the TSDB's core features.	8 years ago
Fabian Reinartz	e478d0e3bc	Actually close olds blocks in reloadBlocks ... This fixes a bug leaking memory because blocks were not actually closed as the closing call references the initial, empty slice	8 years ago

Fabian Reinartz	9c93f8f2aa	Fix various races ... This fixes different race condition encoutnered when running Prometheus. It reduces the overall performance in the synthetic benchmark a fair bit but has no indiciations of impacting a real-world setup notably.	8 years ago
Fabian Reinartz	3635569257	Trigger reload correctly on interrupted compaction	8 years ago
Fabian Reinartz	2c999836fb	Add Queryable interface to Block ... This adds the Queryable interface to the Block interface. Head and persisted blocks now implement their own Querier() method and thus isolate customization (e.g. remapPostings) more cleanly.	8 years ago
