82973f8ae7 Revert "lib/storage: remove unused fetchData arg from BlockRef.MustReadBlock" 
This reverts commit bab6a15ae0.

Reason for revert: the `fetchData` arg is used in cluster branch.
Leaving this arg in master branch makes smaller the diff with cluster branch.

39dee12ed7 lib/persistentqueue: code simplification after d455764a6f 2020-09-16 21:14:19 +03:00
Aliaksandr Valialkin
d455764a6f lib/persistentqueue: make the persistent queue more durable against unclean shutdown (kill -9, OOM, hard reset) 
The strategy is:

- Periodical flushing of inmemory blocks to files, so they aren't lost on unclean shutdown.
- Periodical syncing of metadata for persisted queues, so the metadata remains in sync with the persisted data.
- Automatic adjusting of too big chunk size when opening the queue. The chunk size may be bigger than the writer offset after unclean shutdown.
- Skipping of broken chunk file if it cannot be read.
- Fsyncing finalized chunk files.

Added endpointslices discovery to k8s api (#760) 
This is similar to https://github.com/prometheus/prometheus/pull/6838 , which will be added in Prometheus v2.21.
See https://github.com/prometheus/prometheus/releases/tag/v2.21.0-rc.1

* Added endpointslices discovery to k8s api

Started from 1.17 k8s version endpointslices is beta,
it allows to query k8s api for endpoints more efficient.
It presents at scrape_config.yaml as separate role for kubernetes_sd_config.
kubernetes_sd_config:
- role: endpointslices

* fixed typos, changed EndpointConditions signature - with values instead of pointers

9d8fdff6c5 lib/storage: reuse timestamp blocks for adjancent metric blocks with identical timestamps 
This should reduce disk space usage when scraping targets containing metrics with identical names
such as `node_cpu_seconds_total`, histograms, quantiles, etc.

Expose `vm_timestamps_blocks_merged_total` and `vm_timestamps_bytes_saved_total` metrics for monitoring
the effectiveness of timestamp blocks merging.

Changed s3 configProfile flag default, (#749) 
aws sdk has complicated logic for chosing profile name and we shouldn't set
it to `default` value. It leads to bugs and improper configuration.
Set it to empty value by default is safe. It will be automatically set to `default` by sdk.
