1. Use distinct code paths for blockResult.getValues() and blockResult.getValuesBucketed().
This should simplify debugging and maintenance of the resulting code.
2. Do not load column values if all the values in the block fit the same bucket.
Use blockResultColumn.minValue and blockResultColumn.maxValue for determining whether
column values must be loaded via blockResultColumn.getValuesEncoded().
This signiciantly improves performance for big buckets, which cover all the column
values in a block.
3. Properly calculate buckets for negative values.
4. Properly adjust weekly buckets by Monday.

Previously the `callbackErr` is silently ignored in clusternative parser, which is used at vminsert for parsing clusterNative requests and at vmstorage for parsing vminsert requests.
This commit fixes that by properly return callbackError after reading all block metrics. This aligns
with other parsers in `lib/protoparser`.
### Describe Your Changes
Updated default `step` calculation for `Table` and `JSON` views.
- When switching to the `Table` or `JSON` view, the default step is now
automatically set to `end - start`, where `end` and `start` correspond
to the selected time range.
- If the user has manually set a step value, it will remain unchanged
when switching views or changing the time range.
- The UI now explicitly indicates when the step is automatically
calculated.

### Describe Your Changes
There is an issue described in #8040 this should fix it
- The alerts slice is shared across multiple goroutines (since send() is
called concurrently).
- `alerts[:0]` creates a new slice header, but it still references the
same underlying array.
- Appending (append(alertsToSend, a)) modifies the underlying array,
which may also be used by another goroutine.
Solution: Use a separate slice copy for each goroutine.

(cherry picked from commit 04943907e3)
Previously RFC3339 timestamps with sub-second precision could be incorrectly compared by lessString().
For example, 2025-01-20T10:20:30.1Z was incorrectly treated as smaller than 2025-01-20T10:20:30.09Z,
because the first timestamp has smaller decimal number after the last dot than the second timestamp.

Previosly the parsing of the input stream was stopped after the first parse error.
This isn't what most users expect when ingesting JSON lines in a stream where some JSON lines may be invalid.
(cherry picked from commit ebac07bcf6)
Split unique values (groups) into shards according to the configured concurrency
during processing of the matching rows if the number of unique values exceeds the hardcoded threshold.
Previously this splitting was performed unconditionally at the merge stage when merging independently
calculated per-CPU states into a single state. It is faster to perform the split during rows processing
if the number of unique values is big.
This gives up to 30% perfromance improvements when these pipes are applied to big number of unique values (groups).
(cherry picked from commit 48602a1ae8)
The number of worker shards per each pipe processor is created during query initialization.
This number equals to the `options(concurrency=N)` if this option is set or to the number of available CPU cores.
This means that all the pipes must adhere the given concurrency when passing data blocks
to the next pipe.
See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/8201
The bug has been introduced in 0214aa328e
vmauth uses 'lib/httpserver' for serving HTTP requests. This server
unconditionally defines built-in routes (such as '/metrics',
'/health', etc). It makes impossible to proxy `HTTP` requests to backends with the same routes.
Since vmauth's httpserver matches built-in route and return local
response.
This commit adds new flag `httpInternalListenAddr` with
default empty value. Which removes internal API routes from public
router and exposes it at separate http server.
For example given configuration disables private routes at `0.0.0.0:8427` address and serves it at `0.0.0.0:8426`:
`./bin/vmauth --auth.config=config.yaml --httpListenAddr=:8427 --httpInternalListenAddr=127.0.0.1:8426`

This commit improves integration with third-party solutions who rely on non-root
endpoints (i.e. MinIO) when the vmselect path has been specified in the
configured Prometheus URL like:
`http://vmselect.:8481/select/0/prometheus`
Comparable change has been done before
(b885a3b6e9), however only takes care of
the root path. This means endpoints `-/healthy` and `-/ready` are still
not available on full vmselect Prometheus paths, resulting in
unsupported path requests.
This change makes these endpoints available on the full paths like:
`/select/0/prometheus/-/healthy` and `/select/0/prometheus/-/ready`,
thus achieving full Prometheus compatibility for external dependencies.

### Describe Your Changes
The cardinality limiter in this case does not receive the actual
metricID but some other value found in r.TSID.MetricID and is not
initialized. Depending on the system and/or go runtime implementation,
this value can be 0 or some garbage value (which shouldn't have too wide
a range). Thus, there basically no limit for inserted metricIDs.

At this time `bufferedwriter` [silently ignores connection close
errors](78eaa056c0/lib/bufferedwriter/bufferedwriter.go (L67)).
It may be very convenient in some situations (to not log such
unimportant errors), but it's too implicit and unsafe for the others.
For example, if you close [export
API](https://docs.victoriametrics.com/#how-to-export-time-series) client
connection in the middle of communication, VictoriaMetrics won't notice
it and will start to hog CPU by exporting all the data into nowhere
until it process all of them. If you'll make a few retries, it will be
effectively a DoS on the server.
This commit replaces this implicit error suppressing with explicit error
handling which fixes the issue with export API.

This should reduce the time needed for opening the storage with retentions exceeding a few months.
While at at, limit the concurrency of opening partitions in parallel to the number of available CPU cores,

### Describe Your Changes
- Added the `fields_limit` parameter for the `hits` query to limit the
number of returned fields. This reduces the response size and decreases
memory usage.
#### Legend Menu:
A context menu has been added for legend items, which includes:
1. Metric name
2. **Copy _stream name** - copies the full stream name in the format
`{field1="value1", ..., fieldN="valueN"}`.
3. **Add _stream to filter** - adds the full stream value to the current
filter:
`_stream: {field1="value1", ..., fieldN="valueN"} AND (old_expr)`.
4. **Exclude _stream from filter** - excludes the stream from the
current filter:
`(NOT _stream: {field1="value1", ..., fieldN="valueN"}) AND (old_expr)`.
5. List of fields with options:
- Copy as `field: "value"`.
- Add to filter: `field: "value" AND (old_expr)`.
- Exclude from filter: `-field: "value" AND (old_expr)`.
6. Total number of hits for the stream.

The purpose of extra filters ( https://docs.victoriametrics.com/victorialogs/querying/#extra-filters )
is to limit the subset of logs, which can be queried. For example, it is expected that all the queries
with `extra_filters={tenant=123}` can access only logs, which contain `123` value for the `tenant` field.
Previously this wasn't the case, since the provided extra filters weren't applied to subqueries.
For example, the following query could be used to select all the logs outside `tenant=123`, for any `extra_filters` arg:
* | union({tenant!=123})
This commit fixes this by propagating extra filters to all the subqueries.
While at it, this commit also properly propagates [start, end] time range filter from HTTP querying APIs
into all the subqueries, since this is what most users expect. This behaviour can be overriden on per-subquery
basis with the `options(ignore_global_time_filter=true)` option - see https://docs.victoriametrics.com/victorialogs/logsql/#query-options
Also properly apply apply optimizations across all the subqueries. Previously the optimizations at Query.optimize()
function were applied only to the top-level query.
Previously, NewChild elements of querytracer could be referenced by concurrent
storageNode goroutines. After earlier return ( if search.skipSlowReplicas is set), it is
possible, that tracer objects could be still in-use by concurrent workers.
It may cause panics and data races. Most probable case is when parent tracer is finished, but children
still could write data to itself via Donef() method. It triggers read-write data race at trace
formatting.
This commit adds a new methods to the querytracer package, that allows to
create children not referenced by parent and add it to the parent later.
Orphaned child must be registered at the parent, when goroutine returns. It's done synchronously by the single caller via finishQueryTracer call.
If child didn't finished work and reference for it is used by concurrent goroutine, new child must be created instead with
context message.
It prevents panics and possible data races.

This is done via 'options(concurrency=N)' prefix for the query.
For example, the following query is executed on at most 4 CPU cores:
options(concurrency=4) _time:1d | count_uniq(user_id)
This allows reducing RAM and CPU usage at the cost of longer query execution times,
since by default every query is executed in parallel on all the available CPU cores.

This chapter is needed for referring from Github issues when CPU or memory profiles are needed to be collected
in order to investigate issues with high CPU and/or RAM usage at VictoriaLogs.
- url encoding / decoding with <urlencode:field> and <urldecode:field>
- base64 encoding / decoding with <base64encode:field> and <base64decode:field>
- hex encoding / decoding with <hexencode:field> and <hexdecode:field>
- hex encoding for integers with <hexnumencode:field> and <hexnumdecode:field>
Prevsiously integer values were converted to strings before being passed to `updateState()` function at `count_uniq`
and `count_uniq_hash`. Later such values are converted back to integers in order to track them via integer map of unique values.
This commit avoids the int -> string -> int conversion. Instead, it passes integers directly to the integer map of unique values.
This improves performance of `count_uniq` and `count_uniq_hash` functions even further.
This filter can be used when debugging and exploring logs in order to understand better
which value types are used for storing the particular log fields.
The `value_type` filter complements `block_stats` pipe.
- Pass the calculated results to the next pipe in float64 columns.
Previously the results were converted to string columns. This could slow down further calculations.
- Use custom optimized logic for processing numeric columns, which are passed to math pipe.
Previously all the input columns were converted to string and then converted to float64
before math pipe calculations.
- Initialize the newly added columns at blockResult as soon as they are added.
This improves performance when big number of columns are calculated by math pipe.
Previously integer values were tracked in string maps. Now every input value is parsed as integer.
On success the parsed integer is tracked via specialized maps, which hold only integers.
This reduces CPU usage and memory usage in general case.
When vmselect process a rollup function it fetches all the raw samples
on requested `start-end` interval of the query. It then loops through
the raw samples, picks the range of the samples based on provided `step`
interval and invokes a rollup function for each of the picked ranges of
samples.
During this processing, vmselect always populates the `realPrevValue`
field with the closest previous raw sample value before the picked range
of samples. This `realPrevValue` is used by rollup functions like
increase_pure or delta to decide whether the counter change happened or
not. For example, we get the counter value == 1. If we've seen this
counter before and its value was also 1 - then no change happened. If we
didn't see it before, then this counter should have started with value=0
and we need to account for `1-0=1` change. All this is required to deal
with situations when scrapes are missing or `step` is too small.
However, vmselect doesn't check how "old" is the `realPrevValue`. In
other words, it doesn't respect the staleness interval when picking it.
In result, depending on the `start` and `end` params, vmselect can use
`realPrevValue` which is a couple of hours old and is unlikely to be a
temporary scrape fail. In result, some increases can be incorrectly
ingnored by vmselect.
This change makes sure that vmselect doesn't populate `realPrevValue`
with samples that are older than staleness interval.

-------------------
To reproduce, create a dataset with one metric `foo` which has samples
with value=1 on interval of couple of hours and resolution 15s, and a
gap for an hour in the middle:
<img width="769" alt="image"
src="https://github.com/user-attachments/assets/a39b2740-b741-45f8-ad18-093b7c57c3b3"
/>
Then run `increase(foo[1m])` expression on this time range (disable
cache):
<img width="1472" alt="image"
src="https://github.com/user-attachments/assets/463cece1-f359-4c75-a96c-60092a31cab2"
/>
In result, there will be one increase on the beginning of the series.
And no increase after the gap. Then change the time range so it starts
in the middle of the gap:
<img width="1505" alt="image"
src="https://github.com/user-attachments/assets/f4a460c3-9fd1-4ec7-ab47-15e716ec1019"
/>
Now, there is an increase>0 because the `realPrevValue` wasn't
populated. This is wrong, because it hides the increase of the series.
With the fix, the original increase query on full time range should show
2 increases:
<img width="1492" alt="image"
src="https://github.com/user-attachments/assets/aa9d8a6b-7b22-41f6-9eb9-83b3113a6982"

Hint allows to choose type of cache to be used for index search:
- in-memory parts are storing recently ingested samples and should use
main cache. This improves ingestion speed and cache hit ration for
queries accessing recently ingested samples.
- merges of file parts is performed in background, using a separate
cache allows avoiding pollution of the main cache with irrelevant
entries.

This commit makes configurable interval for checking if final dedup
process for the historical data should be started. It allows to spread
resource utilisation for multiple vmstorage/vmsingle instances in time.
Since final dedup may add additional preasure on disk, backup systems
and make cluster less stable. Storage unconditionally adds 25% jitter to
the provided value, it should simplify configuration management at
Kubernetes ecosystem. Because Kubernetes application pods must have the
same configuration.
