* query: set default evaluation interval (thanos-io#1028)

Subqueries allows request with no [specified resolution](https://prometheus.io/blog/2019/01/28/subquery-support/).
Set it up and allow to configure default evaluation interval.

* store+compactor: pre-compute index cache during compaction (thanos-io#986)

Fixes first part of thanos-io#942

This changes allow to safe some startup & sync time in store gateway as it is no longer is needed to compute index-cache from block index on its own. For compatibility store GW still can do it, but it first checks bucket if there is index-cached uploaded already.

In the same time, compactor precomputes the index cache file on every compaction. To allow quicker addition of index cache files we added `--index.generate-missing-cache-file` flag, that if enabled precompute missing files on compactor startup. Note that it will take time and it's only one-off step per bucket.

* bucket verify: repair out of order labels (thanos-io#964)

* bucket verify: repair out of order labels

* verify repair: correctly order series in the index on rewrite

When we have label sets that are not in the correct order, fixing that
changes the order of the series in the index.  So the index must be
rewritten in that new order.  This makes this repair tool take up a
bunch more memory, but produces blocks that verify correctly.

* Fix the TSDB block safe-delete function

The directory name must be the block ID name exactly to verify.  A temp
directory or random name will not work here.

* verify repair: fix duplicate chunk detection

Pointer/reference logic error was eliminating all chunks for a series in
a given TSDB block that wasn't the first chunk.  Chunks are now
referenced correctly via pointers.

* PR feedback: use errors.Errorf() instead of fmt.Errorf()

* Use errors.New()

Some linters catch errors.Errorf() as its not really part of the errors
package.

* Liberally comment this for loop

We're comparing items by pointers, using Go's range variables is
misleading here and we need not fall into the same trap.

* Take advantage of sort.Interface

This prevents us from having to re-implement label sorting.

* PR Feedback: Comments are full sentences.

* Fixed Downsampling process; Fixed runutil.CloseAndCaptureErr

Fixes thanos-io#1065

Root cause:
* runutil defered capture error function was not passing error properly so unit tests were passing, event though there was bug
* streamed block write index cache requires index file which was not closed (saved) properly yet. Closers need to be closed to perform this.

* add compare flags func to compare flags between prometheus and sidecar (thanos-io#838)

Original message:

* update documentation for a max/min block duration

add compare flags func to compare flags between prom and sidecar

* fix some nits


Functional change: now we check the configured flags (if possible) and error out if MinTime != MaxTime. We need to check this always since if that is not true then we will get overlapping blocks. Additionally, an error message is printed out if it is not equal to 2h (the recommended value).

* Ensured index cache is best effort, refactored tests, validated edge cases. (thanos-io#1073)

Fixes thanos-io#651

Current size also includes slice header.

* store/proxy: properly check if context has ended (thanos-io#1082)

How the code was before it could happen that we might receive some
series from the stream however by the time we'd send them back to the
reader, it would not read it anymore since the deadline would have been
exceeded.

Properly use a `select` here to get out of the goroutine if the deadline
has been exceeded.

Might potentially fix a problem where we see one goroutine hanging
constantly (and thus blocking from work being done):

```
goroutine profile: total 126

## Unreleased

### Added
- [#811](https://github.com/improbable-eng/thanos/pull/811) Remote write receiver
- [#798](https://github.com/improbable-eng/thanos/pull/798) Ability to limit the maximum concurrent about of Series() calls in Thanos Store and the maximum amount of samples.
## [v0.4.0](https://github.com/improbable-eng/thanos/releases/tag/v0.4.0) - 2019.05.3

New options:
:warning: **IMPORTANT** :warning: This is the last release that supports gossip. From Thanos v0.5.0, gossip will be completely removed.

* `--store.grpc.series-sample-limit` limits the amount of samples that might be retrieved on a single Series() call. By default it is 0. Consider enabling it by setting it to more than 0 if you are running on limited resources.
* `--store.grpc.series-max-concurrency` limits the number of concurrent Series() calls in Thanos Store. By default it is 20. Considering making it lower or bigger depending on the scale of your deployment.
This release also disables gossip mode by default for all components.
See [this](docs/proposals/approved/201809_gossip-removal.md) for more details.

New metrics:
* `thanos_bucket_store_queries_dropped_total` shows how many queries were dropped due to the samples limit;
* `thanos_bucket_store_queries_concurrent_max` is a constant metric which shows how many Series() calls can concurrently be executed by Thanos Store;
* `thanos_bucket_store_queries_in_flight` shows how many queries are currently "in flight" i.e. they are being executed;
* `thanos_bucket_store_gate_duration_seconds` shows how many seconds it took for queries to pass through the gate in both cases - when that fails and when it does not.
### Added

New tracing span:
* `store_query_gate_ismyturn` shows how long it took for a query to pass (or not) through the gate.
- [thanos.io](https://thanos.io) website & automation :tada:
- [#1053](https://github.com/improbable-eng/thanos/pull/1053) compactor: Compactor & store gateway now handles incomplete uploads gracefully. Added hard limit on how long block upload can take (30m).
- [#811](https://github.com/improbable-eng/thanos/pull/811) Remote write receiver component :heart: :heart: thanks to RedHat (@brancz) contribution.
- [#910](https://github.com/improbable-eng/thanos/pull/910) Query's stores UI page is now sorted by type and old DNS or File SD stores are removed after 5 minutes (configurable via the new `--store.unhealthy-timeout=5m` flag).
- [#905](https://github.com/improbable-eng/thanos/pull/905) Thanos support for Query API: /api/v1/labels. Notice that the API was added in Prometheus v2.6.
- [#798](https://github.com/improbable-eng/thanos/pull/798) Ability to limit the maximum number of concurrent request to Series() calls in Thanos Store and the maximum amount of samples we handle.
- [#1060](https://github.com/improbable-eng/thanos/pull/1060) Allow specifying region attribute in S3 storage configuration

:warning: **WARNING** :warning: #798 adds a new default limit to Thanos Store: `--store.grpc.series-max-concurrency`. Most likely you will want to make it the same as `--query.max-concurrent` on Thanos Query.

- [#970](https://github.com/improbable-eng/thanos/pull/970) Added `PartialResponseStrategy` field for `RuleGroups` for `Ruler`.
New options:

New Store flags:

* `--store.grpc.series-sample-limit` limits the amount of samples that might be retrieved on a single Series() call. By default it is 0. Consider enabling it by setting it to more than 0 if you are running on limited resources.
* `--store.grpc.series-max-concurrency` limits the number of concurrent Series() calls in Thanos Store. By default it is 20. Considering making it lower or bigger depending on the scale of your deployment.

New Store metrics:

* `thanos_bucket_store_queries_dropped_total` shows how many queries were dropped due to the samples limit;
* `thanos_bucket_store_queries_concurrent_max` is a constant metric which shows how many Series() calls can concurrently be executed by Thanos Store;
* `thanos_bucket_store_queries_in_flight` shows how many queries are currently "in flight" i.e. they are being executed;
* `thanos_bucket_store_gate_duration_seconds` shows how many seconds it took for queries to pass through the gate in both cases - when that fails and when it does not.

- [#1016](https://github.com/improbable-eng/thanos/pull/1016) Added option for another DNS resolver (miekg/dns client).
Note that this is required to have SRV resolution working on [Golang 1.11+ with KubeDNS below v1.14](https://github.com/golang/go/issues/27546)

New Querier and Ruler flag: `-- store.sd-dns-resolver` which allows to specify resolver to use. Either `golang` or `miekgdns`

- [#986](https://github.com/improbable-eng/thanos/pull/986) Allow to save some startup & sync time in store gateway as it is no longer needed to compute index-cache from block index on its own for larger blocks.
The store Gateway still can do it, but it first checks bucket if there is index-cached uploaded already.
In the same time, compactor precomputes the index cache file on every compaction.

New Compactor flag: `--index.generate-missing-cache-file` was added to allow quicker addition of index cache files. If enabled it precomputes missing files on compactor startup. Note that it will take time and it's only one-off step per bucket.

- [#887](https://github.com/improbable-eng/thanos/pull/887) Compact: Added new `--block-sync-concurrency` flag, which allows you to configure number of goroutines to use when syncing block metadata from object storage.
- [#928](https://github.com/improbable-eng/thanos/pull/928) Query: Added `--store.response-timeout` flag. If a Store doesn't send any data in this specified duration then a Store will be ignored and partial data will be returned if it's enabled. 0 disables timeout.
- [#893](https://github.com/improbable-eng/thanos/pull/893) S3 storage backend has graduated to `stable` maturity level.
- [#936](https://github.com/improbable-eng/thanos/pull/936) Azure storage backend has graduated to `stable` maturity level.
- [#937](https://github.com/improbable-eng/thanos/pull/937) S3: added trace functionality. You can add `trace.enable: true` to enable the minio client's verbose logging.
- [#953](https://github.com/improbable-eng/thanos/pull/953) Compact: now has a hidden flag `--debug.accept-malformed-index`. Compaction index verification will ignore out of order label names.
- [#963](https://github.com/improbable-eng/thanos/pull/963) GCS: added possibility to inline ServiceAccount into GCS config.
- [#1010](https://github.com/improbable-eng/thanos/pull/1010) Compact: added new flag `--compact.concurrency`. Number of goroutines to use when compacting groups.
- [#1028](https://github.com/improbable-eng/thanos/pull/1028) Query: added `--query.default-evaluation-interval`, which sets default evaluation interval for sub queries.
- [#980](https://github.com/improbable-eng/thanos/pull/980) Ability to override Azure storage endpoint for other regions (China)
- [#1021](https://github.com/improbable-eng/thanos/pull/1021) Query API `series` now supports POST method.
- [#939](https://github.com/improbable-eng/thanos/pull/939) Query API `query_range` now supports POST method.

### Changed
- [#970](https://github.com/improbable-eng/thanos/pull/970) Deprecated partial_response_disabled proto field. Added partial_response_strategy instead. Both in gRPC and Query API.
- [#970](https://github.com/improbable-eng/thanos/pull/970) No `PartialResponseStrategy` field for `RuleGroups` by default means `abort` strategy (old PartialResponse disabled) as this is recommended option for Rules and alerts.

- [#970](https://github.com/improbable-eng/thanos/pull/970) Deprecated `partial_response_disabled` proto field. Added `partial_response_strategy` instead. Both in gRPC and Query API.
No `PartialResponseStrategy` field for `RuleGroups` by default means `abort` strategy (old PartialResponse disabled) as this is recommended option for Rules and alerts.

Metrics:

* Added `thanos_rule_evaluation_with_warnings_total` to Ruler.
* DNS `thanos_ruler_query_apis*` are now `thanos_ruler_query_apis_*` for consistency.
* DNS `thanos_querier_store_apis*` are now `thanos_querier_store_apis__*` for consistency.
* Query Gate `thanos_bucket_store_series*` are now `thanos_bucket_store_series_*` for consistency.
* Most of thanos ruler metris related to rule manager has `strategy` label.

Ruler tracing spans:

* `/rule_instant_query HTTP[client]` is now `/rule_instant_query_part_resp_abort HTTP[client]"` if request is for abort strategy.

- [#1009](https://github.com/improbable-eng/thanos/pull/1009): Upgraded Prometheus (~v2.7.0-rc.0 to v2.8.1) and TSDB (`v0.4.0` to `v0.6.1`) deps.

Changes that affects Thanos:
* query:
* [ENHANCEMENT] In histogram_quantile merge buckets with equivalent le values. #5158.
* [ENHANCEMENT] Show list of offending labels in the error message in many-to-many scenarios. #5189
* [BUGFIX] Fix panic when aggregator param is not a literal. #5290
* ruler:
* [ENHANCEMENT] Reduce time that Alertmanagers are in flux when reloaded. #5126
* [BUGFIX] prometheus_rule_group_last_evaluation_timestamp_seconds is now a unix timestamp. #5186
* [BUGFIX] prometheus_rule_group_last_duration_seconds now reports seconds instead of nanoseconds. Fixes our [issue #1027](https://github.com/improbable-eng/thanos/issues/1027)
* [BUGFIX] Fix sorting of rule groups. #5260
* store: [ENHANCEMENT] Fast path for EmptyPostings cases in Merge, Intersect and Without.
* tooling: [FEATURE] New dump command to tsdb tool to dump all samples.
* compactor: [ENHANCEMENT] When closing the db any running compaction will be cancelled so it doesn't block.

For ruler essentially whole TSDB CHANGELOG applies beween v0.4.0-v0.6.1: https://github.com/prometheus/tsdb/blob/master/CHANGELOG.md

Note that this was added on TSDB and Prometheus: [FEATURE] Time-ovelapping blocks are now allowed. #370
Whoever due to nature of Thanos compaction (distributed systems), for safety reason this is disabled for Thanos compactor for now.
