Sometimes users may use the wrong (lower) version of Grafana when
setting up the VictoriaLogs datasource.
It would be good to document the requirements of Grafana versions to use
VictoriaMetrics/VictoriaLogs datasource.

Changes to .ts files in vmui or vmui for logs require re-building
static files that will be included into compiled binary afterwards.
We don't update static files on each .ts change PR because it results
in too many changes and complicates review.
So we need to update these static files before the actual release.

(cherry picked from commit e5d279bb71)
This reverts commit e280d90e9a.
Reason for revert: the updated code doesn't improve the performance of table.MustAddRows for the typical case
when rows contain timestamps belonging to ptws[0].
The performance may be improved in theory for the case when all the rows belong to partiton other than ptws[0],
but this partition is automatically moved to ptws[0] by the code at lines
6aad1d43e9/lib/storage/table.go (L287-L298) ,
so the next time the typical case will work.
Also the updated code makes the code harder to follow, since it introduces an additional level of indirection
with non-trivial semantics inside table.MustAddRows - the partition.TimeRangeInPartition() function.
This function needs to be inspected and understood when reading the code at table.MustAddRows().
This function depends on minTsInRows and maxTsInRows vars, which are defined and initialized
many lines above the partition.TimeRangeInPartition() call. This complicates reading and understanding
the code even more.
The previous code was using clearer loop over rows with the clear call to partition.HasTimestamp()
for every timestamp in the row. The partition.HasTimestamp() call is used in the table.MustAddRows()
function multiple times. This makes the use of partition.HasTimestamp() call more consistent,
easier to understand and easier to maintain comparing to the mix of partition.HasTimestamp() and partition.TimeRangeInPartition()
calls.
Aslo, there is no need in documenting some hardcore software engineering refactoring at docs/CHANGLELOG.md,
since the docs/CHANGELOG.md is intended for VictoriaMetrics users, who may not know software engineering.
The docs/CHANGELOG.md must document user-visible changes, and the docs must be concise and clear for VictoriaMetrics users.
See https://docs.victoriametrics.com/contributing/#pull-request-checklist for more details.

Relative links in docs are much harder to maintain in consistent state comparing to absolute links:
- It is non-trivial to figure out the proper relative link path when creating and editing docs.
- Relative links break after moving the doc files to another paths, and it is non-trivial
to figure which links are broken after that.
See also f357ee57ef , d5809f8e12 and 8cb1822b94
- Document `make docs-debug` command at https://docs.victoriametrics.com/#documentation
- Remove unneeded ROOTDIR, REPODIR and WORKDIR env vars from docs/Makefile ,
since it is documented and expected that all the Makefile commands are run from the repository root.
- Use `docker --rm` for running Docker container with local docs server, so it is automatically
removed after pressing `Ctrl+C`. This makes the container cleanup automatic.

The /some_path/.+ regexp matches /some_path/ followed by at least a single char.
This is unexpected by most users, since they expect it should match /some_path/.
Substitute .+ with .*, so this regexp matches /some_path/ .
There is no need in enumerating all the files, which must be updated, since these files
may be moved to other locations. It is enough to mention that versions for all the VictoriaMetrics
components must be updated.

### Checklist
The following checks are **mandatory**:
- [x] My change adheres [VictoriaMetrics contributing
guidelines](https://docs.victoriametrics.com/contributing/).
- Mention that credentials can be configured via env variables at both vmbackup and vmrestore docs.
- Make clear that the AZURE_STORAGE_DOMAIN env var is optional at https://docs.victoriametrics.com/vmbackup/#providing-credentials-via-env-variables
- Use string literals as is for env variable names instead of indirecting them via string constants.
This makes easier to read and understand the code. These environment variable names aren't going to change
in the future, so there is no sense in hiding them under string constants with some other names.
- Refer to https://docs.victoriametrics.com/vmbackup/#providing-credentials-via-env-variables in error messages
when auth creds are improperly configured. This should simplify figuring out how to fix the error.
- Simplify the code a bit at FS.newClient(), so it is easier to follow it now.
While at it, remove the check when superflouos environment variables are set, since it is too fragile
and it looks like it doesn't help properly configuring vmbackup / vmrestore.
- Remove envLookuper indirection - just use 'func(name string) (string, bool)' type inline.
This simplifies code reading and understanding.
- Split TestFSInit() into TestFSInit_Failure() and TestFSInit_Success(). This simplifies the test code,
so it should be easier to maintain in the future.

- Clarify the description of -graphite.sanitizeMetricName command-line flag at README.md
- Do not sanitize tag values - only metric names and tag names must be sanitized,
since they are treated specially by Grafana. Grafana doesn't apply any restrictions on tag values.
- Properly replace more than two consecutive dots with a single dot.
- Disallow unicode letters in metric names and tag names, since neither Prometheus nor Grafana
do not support them.

`Storage.AddRows()` returns an error only in one case: when
`Storage.updatePerDateData()` fails to unmarshal a `metricNameRaw`. But
the same error is treated as a warning when it happens inside
`Storage.add()` or returned by `Storage.prefillNextIndexDB()`.
This commit fixes this inconsistency by treating the error returned by
`Storage.updatePerDateData()` as a warning as well. As a result
`Storage.add()` does not need a return value anymore and so doesn't
`Storage.AddRows()`.
Additionally, this commit adds a unit test that checks all cases that
result in a row not being added to the storage.

The purpose of docs/CHANGELOG.md is to provide VictoriaMetrics users clear and concise information
on what's changed at VictoriaMetrics components. Technical details of the change are unclear
to most of VictoriaMetrics users, who are not familiar with VictoriaMetrics source code.
These details complicate reading the docs/CHANGELOG.md by ordinary users, so do not clutter
the changelog with technical details. If the user wants technical details, he can click
the link to the related GitHub issue and/or pull request and dive into all the details he wants.
This reverts commit 4d66e042e3.
Reasons for revert:
- The commit makes unrelated invalid changes to docs/CHANGELOG.md
- The changes at app/vmauth/main.go are too complex. It is better splitting them into two parts:
- pooling readTrackingBody struct for reducing pressure on GC
- avoiding to use readTrackingBody when -maxRequestBodySizeToRetry command-line flag is set to 0
Let's make this in the follow-up commits!

Updates https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6533
- Obtain IAM token via GCE-like API instead of Amazon EC2 IMDSv2 API,
since it looks like IMDBSv2 API isn't supported by Yandex Cloud
according to https://yandex.cloud/en/docs/security/standard/authentication#aws-token :
> So far, Yandex Cloud does not support version 2, so it is strongly recommended
> to technically disable getting a service account token via the Amazon EC2 metadata service.
- Try obtaining IAM token via GCE-like API at first and then fall back to the deprecated Amazon EC2 IMDBSv1.
This should prevent from auth errors for instances with disabled GCE-like auth API.
This addresses @ITD27M01 concern at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5513#issuecomment-1867794884
- Make more clear the description of the change at docs/CHANGELOG.md , add reference to the related issue.
P.S. This change wasn't tested in prod because I have no access to Yandex Cloud.
It is recommended to test this change by @ITD27M01 and @vmazgo , who filed
the issue https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5513
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6524
- Move the test for SRV discovery into a separate function. This allows verifying round-robin discovery across SRV records.
- Restore the original netutil.Resolver after the test finishes, so it doesn't interfere with other tests.
- Move the description of the bugfix into the correct place at docs/CHANGELOG.md - it should be placed under v1.102.0-rc2
instead of v1.102.0-rc1.
- Remove unneeded code in URLPrefix.sanitizeAndInitialize(), since it is expected this function is called only once
for finishing URLPrefix initializiation. In this case URLPrefix.nextDiscoveryDeadline and URLPrefix.n are equal to 0
according to https://pkg.go.dev/sync/atomic#Uint64
- Properly fix the bug at URLPrefix.discoverBackendAddrsIfNeeded() - it is expected that hostToAddrs map uses
the original hostname keys, including 'srv+' prefix, so it shouldn't be removed when looping over up.busOriginal.
Instead, the 'srv+' prefix must be removed from the hostname only locally before passing the hostname to netutil.Resolver.LookupSRV.
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6401
- Move the remaining code responsible for stream aggregation initialization from remotewrite.go to streamaggr.go .
This improves code maintainability a bit.
- Properly shut down streamaggr.Aggregators initialized inside remotewrite.CheckStreamAggrConfigs().
This prevents from potential resource leaks.
- Use separate functions for initializing and reloading of global stream aggregation and per-remoteWrite.url stream aggregation.
This makes the code easier to read and maintain. This also fixes INFO and ERROR logs emitted by these functions.
- Add an ability to specify `name` option in every stream aggregation config. This option is used as `name` label
in metrics exposed by stream aggregation at /metrics page. This simplifies investigation of the exposed metrics.
- Add `path` label additionally to `name`, `url` and `position` labels at metrics exposed by streaming aggregation.
This label should simplify investigation of the exposed metrics.
- Remove `match` and `group` labels from metrics exposed by streaming aggregation, since they have little practical applicability:
it is hard to use these labels in query filters and aggregation functions.
- Rename the metric `vm_streamaggr_flushed_samples_total` to less misleading `vm_streamaggr_output_samples_total` .
This metric shows the number of samples generated by the corresponding streaming aggregation rule.
This metric has been added in the commit 861852f262 .
See https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6462
- Remove the metric `vm_streamaggr_stale_samples_total`, since it is unclear how it can be used in practice.
This metric has been added in the commit 861852f262 .
See https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6462
- Remove Alias and aggrID fields from streamaggr.Options struct, since these fields aren't related to optional params,
which could modify the behaviour of the constructed streaming aggregator.
Convert the Alias field to regular argument passed to LoadFromFile() function, since this argument is mandatory.
- Pass Options arg to LoadFromFile() function by reference, since this structure is quite big.
This also allows passing nil instead of Options when default options are enough.
- Add `name`, `path`, `url` and `position` labels to `vm_streamaggr_dedup_state_size_bytes` and `vm_streamaggr_dedup_state_items_count` metrics,
so they have consistent set of labels comparing to the rest of streaming aggregation metrics.
- Convert aggregator.aggrStates field type from `map[string]aggrState` to `[]aggrOutput`, where `aggrOutput` contains the corresponding
`aggrState` plus all the related metrics (currently only `vm_streamaggr_output_samples_total` metric is exposed with the corresponding
`output` label per each configured output function). This simplifies and speeds up the code responsible for updating per-output
metrics. This is a follow-up for the commit 2eb1bc4f81 .
See https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6604
- Added missing urls to docs ( https://docs.victoriametrics.com/stream-aggregation/ ) in error messages. These urls help users
figuring out why VictoriaMetrics or vmagent generates the corresponding error messages. The urls were removed for unknown reason
in the commit 2eb1bc4f81 .
- Fix incorrect update for `vm_streamaggr_output_samples_total` metric in flushCtx.appendSeriesWithExtraLabel() function.
While at it, reduce memory usage by limiting the maximum number of samples per flush to 10K.

- Consistently enumerate stream aggregation outputs in alphabetical order across the source code and docs.
This should simplify future maintenance of the corresponding code and docs.
- Fix the link to `rate_sum()` at `see also` section of `rate_avg()` docs.
- Make more clear the docs for `rate_sum()` and `rate_avg()` outputs.
- Encapsulate output metric suffix inside rateAggrState. This eliminates possible bugs related
to incorrect suffix passing to newRateAggrState().
- Rename rateAggrState.total field to less misleading rateAggrState.increase name, since it calculates
counter increase in the current aggregation window.
- Set rateLastValueState.prevTimestamp on the first sample in time series instead of the second sample.
This makes more clear the code logic.
- Move the code for removing outdated entries at rateAggrState into removeOldEntries() function.
This make the code logic inside rateAggrState.flushState() more clear.
- Do not write output sample with zero value if there are no input series, which could be used
for calculating the rate, e.g. if only a single sample is registered for every input series.
- Do not take into account input series with a single registered sample when calculating rate_avg(),
since this leads to incorrect results.
- Move {rate,total}AggrState.flushState() function to the end of rate.go and total.go files, so they look more similar.
This shuld simplify future mantenance.
