Previously only logs inside the selected time range could be returned by stream_context pipe.
For example, the following query could return up to 10 surrounding logs only for the last 5 minutes,
while most users expect this query should return up to 10 surrounding logs without restrictions on the time range.
_time:5m panic | stream_context before 10
This enables the ability to implement stream context feature at VictoriaLogs web UI: https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7063 .
Reduce memory usage when returning stream context over big log streams with millions of entries.
The new logic scans over all the log messages for the selected log stream, while keeping in memory only
the given number of surrounding logs. Previously all the logs for the given log stream on the selected time range
were loaded in memory before selecting the needed surrounding logs.
This should help https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6730 .
Reduce the scan performance for big log streams by fetching only the requested fields. For example, the following
query should be executed much faster than before if logs contain many fields other than _stream, _msg and _time:
panic | stream_context after 30 | fields _stream, _msg, _time
Use local timezone of the host server in this case. The timezone can be overridden
with TZ environment variable if needed.
While at it, allow using whitespace instead of T as a delimiter between data and time
in the ingested _time field. For example, '2024-09-20 10:20:30' is now accepted
during data ingestion. This is valid ISO8601 format, which is used by some log shippers,
so it should be supported. This format is also known as SQL datetime format.
Also assume local time zone when time without timezone information is passed to querying APIs.
Previously such a time was parsed in UTC timezone. Add `Z` to the end of the time string
if the old behaviour is preferred.

### Describe Your Changes
VictoriaLogs allows logs without `_msg` field or `_msg` field is empty.
This lead to incorrect search result. See:
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6785
This pull request search for non-empty `_msg` field before log entry is
added to `LogRows`.
New counter `vl_rows_dropped_total{reason="msg_not_exist"}` is
introduced.
Example log output:
```

Previously the original timestamp was used in the copied query, so _time:duration filters
were applied to the original time range: (timestamp-duration ... timestamp]. This resulted
in stopped live tailing, since new logs have timestamps bigger than the original time range.
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7028
This pipe is useful for debugging purposes when the number of processed blocks must be calculated for the given query:
<query> | blocks_count

It is expected that range_first and range_last functions return non-nan const value across all the points
if the original series contains at least a single non-NaN value. Previously this rule was violated for NaN data points
in the original series. This could confuse users.
While at it, add tests for series with NaN values across all the range_* and running_* functions, in order to maintain
consistent handling of NaN values across these functions.

Substituting `|` with `or` inside `math` pipe fixes this ambiguity.

Previously per-token hashes for per-block bloom filters were re-calculated on every scanned block.
This could be slow when the number of tokens is big or when the number of blocks to scan is big.
Pre-calculate hashes for bloom filters and then use them for searching in bloom filters.
This improves performance by 2.5x for in(...) filters with many values to search inside `in()`.
Previous bugfix at 49f63b2 only partially fixed pagination host validation error.
Before this fix it was:
```
unexpected nextLink host \"management.azure.com\", expecting \"https://management.azure.com\"
```
Now we only check the `Host` without schema.
However, when Azure respond `nextLink` in `Host:Port` format, the
`nextLink` check will fail:
```
unexpected nextLink host \"management.azure.com:443\", expecting \"management.azure.com\"
```
This pull request further relaxes the checks by only checking the
`Hostname`.

Previously (f1:foo OR f2:bar) was incorrectly returning `foo` token for `f1` and `bar` token for `f2`.
These tokens were used for checking against bloom filter for every data block, so the data block,
which didn't contain simultaneously `foo` token for `f1` field and `bar` token for `f2` field, was skipped.
This was incorrect, since such a block may contain logs matching the original OR filter.
The fix is to return common tokens from `OR`-delimted filters only if these tokens exist at EVERY such filter
for the given field name. If some `OR`-delimited filter misses the given field name, then `OR`-delimited filters
do not contain common tokens, which could be used for checking against bloom filter.
While at it, add more tests covering various edge cases for filters delimited by AND and OR.

…specifying `-streamAggr.dedupInterval` or
`-remoteWrite.streamAggr.dedupInterval` command-line flag
[The
documentation](https://docs.victoriametrics.com/stream-aggregation/)
contains conflicting descriptions regarding deduplication for
non-matched series when `-remoteWrite.streamAggr.config` and / or
`-streamAggr.config` are set:
1. Statement below says **all the received data** is deduplicated:
>[vmagent](https://docs.victoriametrics.com/vmagent/) supports
relabeling, deduplication and stream aggregation for all the received
data, scraped or pushed. Then, the collected data will be forwarded to
specified -remoteWrite.url destinations. The data processing order is
the following:
>1. all the received data is relabeled according to the specified
[-remoteWrite.relabelConfig](https://docs.victoriametrics.com/vmagent/#relabeling)
(if it is set)
>2. all the received data is deduplicated according to specified
[-streamAggr.dedupInterval](https://docs.victoriametrics.com/stream-aggregation/#deduplication)
(if it is set to duration bigger than 0)
2. Another statement says the deduplication is performed individually
for the **matching samples**
>The de-deduplication is performed after applying
[relabeling](https://docs.victoriametrics.com/vmagent/#relabeling) and
before performing the aggregation. If the -remoteWrite.streamAggr.config
and / or -streamAggr.config is set, then the de-duplication is performed
individually per each [stream aggregation
config](https://docs.victoriametrics.com/stream-aggregation/#stream-aggregation-config)
for the matching samples after applying
[input_relabel_configs](https://docs.victoriametrics.com/stream-aggregation/#relabeling).
Considering the following deduplication use cases:
1. To apply deduplication(globally or for specific remoteWrite
destination) for all the received data, scraped or pushed
--- using `-streamAggr.dedupInterval` or
`-remoteWrite.streamAggr.dedupInterval`.
2. To deduplicate and aggregate metrics that match the rule `match`
filters
--- using `-remoteWrite.streamAggr.config` and specifiying
`dedup_interval` option in [stream aggregation
config](https://docs.victoriametrics.com/stream-aggregation/#stream-aggregation-config).
3. To deduplicate all the received data while having `streamAggr.config`
for some metrics
--- no way for a single vmagent now, need to set up two level vmagents
