Revert "lib/promscrape: do not store last scrape response when stale markers … ()"
This reverts commit cfec258803.

Reason for revert: the original code already doesn't store the last scrape response when stale markers are disabled.
The scrapeWork.areIdenticalSeries() function always returns true is stale markers are disabled.
This prevents from storing the last response at scrapeWork.processScrapedData().

It looks like the reverted commit could also return back the issue https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3660

lib/promscrape/discovery/kubernetes: fix watcher start order for roles endpoints and endpointslice ()
* lib/promscrape/discovery/kubernetes: fix watcher start order for roles endpoints and endpointslice

Previously the groupWatcher could be mistakenly stopped when requests for pod or services resources take too long.

* remove mislead comment

* docs/sd_configs.md: mention -promscrape.kubernetes.attachNodeMetadataAll flag in the description for attach_metadata section

Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4640

* wip

* lib/promscrape/kubernetes: prevent from stopping groupWatcher when there are in-flight apiWatcher.mustStart() calls

groupWatcher is stopped if it has zero registered apiWatchers during 14 seconds.
But such a groupWatcher can be still in use if apiWatcher for `role: endpoints` or `role: endpointslice`
is being registered and the discovery of the associated `pod` and/or `service` objects takes longer
than 14 seconds - see the beginning of groupWatcher.startWatchersForRole() function for details.

Track the number of in-flight calls to apiWatcher.mustStart() and prevent from stopping the associated groupWatcher
if the number of in-flight calls is non-zero.

P.S. postponing the discovery of `pod` and/or `service` objects associated with `endpoints` or `endpointslice` roles
isn't the best solution, since it slows down initial discovery of `endpoints` and `endpointslice` targets.

* typo fix

Examples:

1) -metricsAuthKey=file:///abs/path/to/file - reads flag value from the given absolute filepath
2) -metricsAuthKey=file://./relative/path/to/file - reads flag value from the given relative filepath
3) -metricsAuthKey=http://some-host/some/path?query_arg=abc - reads flag value from the given url

The flag value is automatically updated when the file contents changes.

app/vmselect: abort streaming connections for vmselect ()
* app/vmselect: abort streaming connections for vmselect
due to streaming nature of export APIs, curl and simmilr tools cannot
detect errors that happened after http.Header with status 200 was
written to it.

This PR tracks if body write was already started and closes connection.

It allows client to detect not expected chunk sequence and return error
to the caller.

Mostly it affects vmselect at cluster version

lib/storage: follow-up for 4b8088e377
- Clarify the bugfix description at docs/CHANGELOG.md
- Simplify the code by accessing prefetchedMetricIDs struct under the lock
  instead of using lockless access to immutable struct.
  This shouldn't worsen code scalability too much on busy systems with many CPU cores,
  since the code executed under the lock is quite small and fast.
  This allows removing cloning of prefetchedMetricIDs struct every time
  new metric names are pre-fetched. This should reduce load on Go GC,
  since the cloning of uin64set.Set struct allocates many new objects.

app/vmselect/promql: consistently sort results of a or b query
Previously the order of results returned from `a or b` query could change with each request
because the sorting for such query has been disabled in order to satisfy
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4763 .

This commit executes `a or b` query as `sortByMetricName(a) or sortByMetricName(b)`.
This makes the order of returned time series consistent across requests,
while maintaining the requirement from https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4763 ,
e.g. `b` results are consistently put after `a` results.

app/vmalert/remotewrite: properly calculate vmalert_remotewrite_dropped_rows_total
It was calculating the number of dropped time series instead of the number of dropped samples.

While at it, drop vmalert_remotewrite_dropped_bytes_total metric, since it was inconsistently calculated -
at one place it was calculating raw protobuf-encoded sample sizes, while at another place it was calculating
the size of snappy-compressed prompbmarshal.WriteRequest protobuf message.
Additionally, this metric has zero practical sense, so just drop it in order to reduce the level of confusion.

after the commit 487f6380d0 on all the vmagent instances
in cluster mode ( https://docs.victoriametrics.com/vmagent.html#scraping-big-number-of-targets ).

This commit improves debuggability of targets in cluster mode by providing a list of -promscrape.cluster.memberNum
values per each target at /service-discovery page, which has been dropped becasue of sharding,
e.g. if this target is scraped by other vmagent instances in the cluster.

- Add Try* prefix to functions, which return bool result in order to improve readability and reduce the probability of missing check
  for the result returned from these functions.

- Call the adjustSampleValues() only once on input samples. Previously it was called on every attempt to flush data to peristent queue.

- Properly restore the initial state of WriteRequest passed to tryPushWriteRequest() before returning from this function
  after unsuccessful push to persistent queue. Previously a part of WriteRequest samples may be lost in such case.

- Add -remoteWrite.dropSamplesOnOverload command-line flag, which can be used for dropping incoming samples instead
  of returning 429 Too Many Requests error to the client when -remoteWrite.disableOnDiskQueue is set and the remote storage
  cannot keep up with the data ingestion rate.

- Add vmagent_remotewrite_samples_dropped_total metric, which counts the number of dropped samples.

- Add vmagent_remotewrite_push_failures_total metric, which counts the number of unsuccessful attempts to push
  data to persistent queue when -remoteWrite.disableOnDiskQueue is set.

- Remove vmagent_remotewrite_aggregation_metrics_dropped_total and vm_promscrape_push_samples_dropped_total metrics,
  because they are replaced with vmagent_remotewrite_samples_dropped_total metric.

- Update 'Disabling on-disk persistence' docs at docs/vmagent.md

app/vmagent: allow to disabled on-disk persistence ()
* app/vmagent: allow to disabled on-disk queue
Previously, it wasn't possible to build data processing pipeline with a
chain of vmagents. In case when remoteWrite for the last vmagent in the
chain wasn't accessible, it persisted data only when it has enough disk
capacity. If disk queue is full, it started to silently drop ingested
metrics.

New flags allows to disable on-disk persistent and immediatly return an
error if remoteWrite is not accessible anymore. It blocks any writes and
notify client, that data ingestion isn't possible.

Main use case for this feature - use external queue such as kafka for
data persistence.

In the scenario when user exports and imports data from one VM to another,
it could possibly lead to OOM exception for destination VM.

Importing a single line with 16MB size taks 1.3GiB RSS memory.
Hence, the limit for `import.maxLineLen` was decreased from 100MB to 10MB
to improve reliability of VictoriaMetrics during imports.

lib/protoparser/promremotewrite: fall back to zstd decoding if Snappy-decoding fails ()
This case is possible after the following steps:
1. vmagent successfully performed handshake with the -remoteWrite.url and the remote storage supports zstd-compressed data.
2. remote storage became unavailable or slow to ingest data, vmagent compressed the collected data into blocks with zstd and puts these blocks to persistent queue on disk.
3. vmagent restarts and the remote storage is unavailable during the handshake, then vmagent falls back to Snappy compression.
4. vmagent starts sending zstd-compressed data from persistent queue to the remote storage, while falsely advertizing it sends Snappy-compressed data.
5. The remote storage receives zstd-compressed data and fails unpacking it with Snappy.

The solution is the same as 12cd32fd75, just fall back to zstd decompression if Snappy decompression fails.

app/vmselect/promql: properly handle duplicate series when merging cached results with the results obtained from the database
evalRollupFuncNoCache() may return time series with identical labels (aka duplicate series)
when performing queries satisfying all the following conditions:

- It must select time series with multiple metric names. For example, {__name__=~"foo|bar"}
- The series selector must be wrapped into rollup function, which drops metric names. For example, rate({__name__=~"foo|bar"})
- The rollup function must be wrapped into aggregate function, which has no streaming optimization.
  For example, quantile(0.9, rate({__name__=~"foo|bar"})

In this case VictoriaMetrics shouldn't return `cannot merge series: duplicate series found` error.
Instead, it should fall back to query execution with disabled cache.

Also properly store the merged results. Previously they were incorrectly stored because of a typo
introduced in the commit 41a0fdaf39

vmcluster: re-routing enhancement ()
* app/vmstorage: close vminsert connections gradually before stopping storage

Implements graceful shutdown approach suggested here - https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4922#issuecomment-1768146878

* app/vmstorage: update graceful shutdown logic

- close connections from vminsert in determenistic order
- update flag description
- lower default timeout to 25 seconds. 25 seconds value was chosen because the lowest default value used in default configuration deployments is 30s(default value in Kubernetes and ansible-playbooks).

lib/protoparser/promremotewrite: fall back to Snappy decoding if zstd decoding fails
This case is possible after the following steps:

1. vmagent tries to perform handshake with the -remoteWrite.url in order to determine whether
   the remote storage supports zstd-compressed data.
2. The remote storage is unavailable during the handshake. In this case vmagent falls back to Snappy compression
   for the data sent to the remote storage.
3. vmagent compresses the collected data into blocks with Snappy and puts these blocks to persistent queue on disk.
4. The remote storage becomes available.
5. vmagent restarts, performs the handshake with the remote storage and detects that it supports zstd-compressed data.
6. vmagent starts sending Snappy-compressed data from persistent queue to the remote storage,
   while falsely advertizing it sends zstd-compressed data.
7. The remote storage receives Snappy-compressed data and fails unpacking it with zstd.

The solution is to just fall back to Snappy decompression if zstd decompression fails.

lib/htmlcomponents: use relative links for the top page and for favicon.ico
This allows hiding VictoriaMetrics components behind proxies with arbitrary path prefixes.
For example, vmagent HTTP handlers can be served via /vmagent/ path prefix:

- http://proxy/vmagent/targets
- http://proxy/vmagent/service-discovery

The path prefix can be arbitrary. For example, below are vmagent urls
for /tenantID/vmagent/ path prefix:

- http://proxy/tenantID/vmagent/targets
- http://proxy/tenantID/vmagent/service-discovery

While at it, consistently serve favicon.ico from any path directory.

Previously entries which were accessed only 1 time weren't cached.
It has been appeared that some rarely executed heavy queries may read indexdb block twice
in a row instead of once. There is no need in caching such a block then.
This change should eliminate cache size spikes for indexdb/dataBlocks when such heavy queries are executed.

Expose -blockcache.missesBeforeCaching command-line flag, which can be used for fine-tuning
the number of cache misses needed before storing the block in the caching.

app/vmselect/promql: optimize repeated SLI-like instant queries with lookbehind windows >= 1d
Repeated instant queries with long lookbehind windows, which contain one of the following rollup functions,
are optimized via partial result caching:

- sum_over_time()
- count_over_time()
- avg_over_time()
- increase()
- rate()

The basic idea of optimization is to calculate

  rf(m[d] @ t)

as

  rf(m[offset] @ t) + rf(m[d] @ (t-offset)) - rf(m[offset] @ (t-d))

where rf(m[d] @ (t-offset)) is cached query result, which was calculated previously

The offset may be in the range of up to 1 hour.

lib/promauth: follow-up for e16d3f5639
- Make sure that invalid/missing TLS CA file or TLS client certificate files at vmagent startup
  don't prevent from processing the corresponding scrape targets after the file becomes correct,
  without the need to restart vmagent.
  Previously scrape targets with invalid TLS CA file or TLS client certificate files
  were permanently dropped after the first attempt to initialize them, and they didn't
  appear until the next vmagent reload or the next change in other places of the loaded scrape configs.

- Make sure that TLS CA is properly re-loaded from file after it changes without the need to restart vmagent.
  Previously the old TLS CA was used until vmagent restart.

- Properly handle errors during http request creation for the second attempt to send data to remote system
  at vmagent and vmalert. Previously failed request creation could result in nil pointer dereferencing,
  since the returned request is nil on error.

- Add more context to the logged error during AWS sigv4 request signing before sending the data to -remoteWrite.url at vmagent.
  Previously it could miss details on the source of the request.

- Do not create a new HTTP client per second when generating OAuth2 token needed to put in Authorization header
  of every http request issued by vmagent during service discovery or target scraping.
  Re-use the HTTP client instead until the corresponding scrape config changes.

- Cache error at lib/promauth.Config.GetAuthHeader() in the same way as the auth header is cached,
  e.g. the error is cached for a second now. This should reduce load on CPU and OAuth2 server
  when auth header cannot be obtained because of temporary error.

- Share tls.Config.GetClientCertificate function among multiple scrape targets with the same tls_config.
  Cache the loaded certificate and the error for one second. This should significantly reduce CPU load
  when scraping big number of targets with the same tls_config.

- Allow loading TLS certificates from HTTP and HTTPs urls by specifying these urls at `tls_config->cert_file` and `tls_config->key_file`.

- Improve test coverage at lib/promauth

- Skip unreachable or invalid files specified at `scrape_config_files` during vmagent startup, since these files may become valid later.
  Previously vmagent was exitting in this case.

The change should improve performance and memory usage during query processing
on machines with big number of CPU cores. The number of parallel workers for
query processing is controlled via `-search.maxWorkersPerQuery` command-line flag.
By default, the number of workers is limited by the number of available CPU cores,
but not more than 32. The limit can be increased via `-search.maxWorkersPerQuery`.

Signed-off-by: hagen1778 <roman@victoriametrics.com>

* wip

- The `-search.maxWorkersPerQuery` command-line flag doesn't limit resource usage,
  so move it from the `resource usage limits` to `troubleshooting` chapter at docs/Single-server-VictoriaMetrics.md

- Make more clear the description for the `-search.maxWorkersPerQuery` command-line flag

- Add the description of `-search.maxWorkersPerQuery` to docs/Cluster-VictoriaMetrics.md

- Limit the maximum value, which can be passed to `-search.maxWorkersPerQuery`, to GOMAXPROCS,
  because bigger values may worsen query performance and increase CPU usage

- Improve the the description of the change at docs/CHANGELOG.md. Mark it as FEATURE instead of BUGFIX,
  since it is closer to a feature than to a bugfix.

app/vmalert: follow-up after c9375cac5e
c9375cac5e

Descriptions were updated in attempt to make it more clear for readers,
re-phrasing and linking missing docs.

`eval_delay` was added to tests to verify it can be unmarshalled.

`eval_delay` is now applied before timestamp alignment to make it more predictable.
Before, if delay < interval the timestamp won't be aligned.

`eval_delay` and `eval_offset` was added to API output.

`PreviouslySentSeriesToRW` converted to private `previouslySentSeriesToRW`.

lib/promscrape: make concurrency control optional ()
* lib/promscrape: make concurrency control optional

Before, `-maxConcurrentInserts` was limiting all calls to `promscrape.Parse`
function: during ingestion and scraping. This behavior is incorrect.
Cmd-line flag `-maxConcurrentInserts` should have effect onl on ingestion.

Since both pipelines use the same `promscrape.Parse` function, we extend it
to make concurrency limiter optional. So caller can decide whether concurrency
should be limited or not.

This commit makes c53b5788b4
obsolete.

Revert "lib/promscrape: add metric vm_promscrape_scrapes_skipped_total ()"
This reverts commit 74301cdbf5.

Reason for revert:

vmagent already provides better approach for detecting slow scrape targets via the following query:

    scrape_duration_seconds / scrape_timeout_seconds > 1

This query depends on automatically generated per-target metrics.
See https://docs.victoriametrics.com/vmagent.html#automatically-generated-metrics for more details.

lib/promscrape/discovery/kubernetes: supress context.Cancelled error in logs

It is possible that context.Cancelled will appear after k8s watcher was closed due to reload(see https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4850).

Logging an error misinforms user and looks like vmagent discovery will stop working even though this does not affect discovery.

lib/promscrape/client: sync timeout for HostClient and http.Client ()
Initially, stream parse mode was reading data from response and parsing it on flight. This was causing longer delay to read the whole response and required increasing timeout value to allow data processing while reading. So that 908e35affd increased timeout value to fix this.

But after 74c00a8762 response in stream parse mode is saved into memory and then parsed eliminating necessity of having timeout value higher that for usual scrape.

fixed applying remoteWrite.label for pushed metrics () ()
vmagent: properly add extra labels before sending data to remote storage

labels from `remoteWrite.label` are now added to sent metrics just before they
 are pushed to `remoteWrite.url` after all relabelings, including stream aggregation relabelings ()

dashboard: fix display of ingested rows rate
Fix display of ingested rows rate for `Samples ingested/s`
and `Samples rate` panels for vmagent's dasbhoard.
Previously, not all ingested protocols were accounted in these panels.
An extra panel `Rows rate` was added to `Ingestion` section to display the split
for rows ingested rate by protocol.

lib/promrelabel: fix relabeling if clause ()
* lib/promrelabel: fix relabeling if clause being applied to labels outside of current context

Relabeling is applied to each metric row separately, but in order to lower amount of memory allocations it is reusing labels.

Functions which are working on current metric row labels are supposed to use only current metric labels by using provided offset, but if clause matcher was using the whole labels set instead of local metrics.

This leaded to invalid relabeling results such as one described here: https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4806

app/vmagent: add ability to shard outgoing data among multiple remote storage systems
Add -remoteWrite.shardByURL command-line flag, which instructs vmagent to spread evenly
outgoing time series data among the configured remote storage systems specified via -remoteWrite.url .

Samples for the same time series go to the same -remoteWrite.url . This allows building horizontally
scalable stream aggregation when samples for counter and histogram series must be aggregated
by the same second-level vmagent instance.

lib/streamaggr: follow-up for 736197179e
- Use a byte slice instead of a map for tracking indexes for matching series.
  This improves performance, since access by slice index is faster than access by map key.
- Re-use the byte slice for tracking indexes for matching series.
  This removes unnecessary memory allocations and improves stream aggregation performance a bit.
- Add an ability to return to the previous behvaiour by specifying -remoteWrite.streamAggr.dropInput command-line flag.
  In this case all the input samples are dropped when stream aggregation is enabled.
- Backport the new stream aggregation behaviour from vmagent to single-node VictoriaMetrics when -streamAggr.config
  option is set.
- Improve docs regarding this change at docs/CHANGELOG.md

* lib/storage: further work on indexdb rotation optimization

- Document the change at docs/CHAGNELOG.md
- Move back various caches from indexDB to Storage. This makes the change less intrusive.
  The dateMetricIDCache now takes into account indexDB generation, so it stores (date, metricID)
  entries for both the current and the next indexDB.
- Consolidate the code responsible for idbNext pre-filling into prefillNextIndexDB() function.
  This improves code readability and maintainability a bit.
- Rewrite and simplify the code responsible for calculating the next retention timestamp.
  Add various tests for corner cases of this code.
- Remove indexdb pre-filling from RegisterMetricNames() function, since this function is rarely called.
  It is OK to add indexdb entries on demand in this function. This simplifies the code.

lib/promscrape: follow-up after 6aa50ca954
- Improve docs
- Hide `debug relabeling` column when -promscrape.dropOriginalLabels command-line flag is set
- Inline the code from the added template functions, since the code is harder to follow
  with the template functions, especially when these functions have misleading names.
  Also, these functions are used only in one place, e.g. they do not reduce the amounts of code.
- Hide `click to show original labels` title at `labels` column when original labels aren't available.
- Show the reason on whey original labels aren't available at /service-discovery page.
