* promql: histogram_fraction for bucket histograms (#16095)

* promql: histogram_fraction for bucket histograms

This PR extends the histogram_fraction function to also work with classic bucket histograms. This is beneficial because it allows expressions like sum(increase(my_bucket{le="0.5"}[10m]))/sum(increase(my_total[10m])) to be written without knowing the actual values of the "le" label, easing the transition to native histograms later on.
It also feels natural since histogram_quantile also can deal with classic histograms.

* Clarify the docs of promtool --{min,max}-time options

State explicitely what kind of timestamps are expected for the
--min-time and --max-time options of promtool tsdb commands.

This is especially important for the dump-openmetrics command as users
could otherwise  mistakenly think it would be in seconds, like the
OpenMetrics timestamps themselves.

* Labels: simpler/faster stringlabels encoding (#16069)

Instead of using varint to encode the size of each label, use a single
byte for size 0-254, or a flag value of 255 followed by the size in
3 bytes little-endian.

This reduces the amount of code, and also the number of branches in
commonly-executed code, so it runs faster.

The maximum allowed label name or value length is now 2^24 or 16MB.

Memory used by labels changes as follows:
* Labels from 0 to 127 bytes length: same
* From 128 to 254: 1 byte less
* From 255 to 16383: 2 bytes more
* From 16384 to 2MB: 1 byte more
* From 2MB to 16MB: same

Labels: panic on string too long.

Slightly more user-friendly than encoding bad data and finding out when
we decode.

Clarify that Labels.Bytes() encoding can change

* [BUGFIX] Top-level: Update GOGC before loading TSDB (#16491)

We should use the configured value, or Prometheus' default of 75%, while
initializing and loading the WAL.

Since the Go default is 100%, most Prometheus users would experience
higher memory usage before the value is configured.

Also: move Go runtime params earlier in initialization. 
E.g. if a module starting up looks at GOMAXPROCS to size something, we
need to have set it already.

* Add a test for aggregation wrapped in ParenExpr

Signed-off-by: Lukasz Mierzwa <l.mierzwa@gmail.com>

* fix(parser): parenthesis around aggregate expression parsing

The position range of nested aggregate expression was wrong, for the
expression "(sum(foo))" the position of "sum(foo)" should be 1-9, but
the parser could not decide the end of the expression on pos 9, instead
it read ahead to pos 10 and then emitted the aggregate. But we only
kept the last closing position (10) and wrote that into the aggregate.

The reason for this is that the parser cannot know from "(sum(foo)" alone
if the aggregate is finished. It could be finished as in "(sum(foo))" but
equally it could continue with group modifier as "(sum(foo) by (bar))".

The fix is to track ")" tokens in a stack in addition to the lastClosing
position, which is overloaded with other things like offset number tracking.

* Try fixing potential deadlocks in discovery

Manager.ApplyConfig() uses multiple locks:
- Provider.mu
- Manager.targetsMtx

Manager.cleaner() uses the same locks but in the opposite order:
- First it locks Manager.targetsMtx
- The it locks Provider.mu

I've seen a few strange cases of Prometheus hanging up on shutdown and never compliting that shutdown.
From a few traces I was given it appears that while Prometheus is still running only discovery.Manager and notifier.Manager are running running.
From that trace it also seems like they are stuck on a lock from two functions:
- cleaner waits on a RLock()
- ApplyConfig waits on a Lock()

I cannot reproduce it but I suspect this is a race between locks. Imagine this scenario:
- Manager.ApplyConfig() is called
- Manager.ApplyConfig locks Provider.mu.Lock()
- at the same time cleaner() is called on the same Provider instance and it calls Manager.targetsMtx.Lock()
- Manager.ApplyConfig() now calls Manager.targetsMtx.Lock() but that lock is already held by cleaner() function so ApplyConfig() hangs there
- at the same time cleaner() now wants to lock Provider.mu.Rlock() but that lock is already held by Manager.ApplyConfig()
- we end up with both functions locking each other out without any way to break that lock

Re-order lock calls to try to avoid this scenario.
I tried writing a test case for it but couldn't hit this issue.

* Optimize memoization and search debouncing on /targets page (#16589)

Moving the debouncing of the search field to the parent component and then
memoizing the ScrapePoolsList component prevents a lot of superfluous
re-renders of the entire scrape pools list that previously got triggered
immediately when you typed in the search box or even just collapsed a pool.
(While the computation of what data to show was already memoized in the
ScrapePoolList component, the component itself still had to re-render a lot
with the same data.)

Discovered this problem + verified fix using react-scan.

* Fix full-page re-rendering when opening status nav menu (#16590)

When opening the status pages menu while already viewing one of the
status pages, the whole page would be re-rendered because the menu target's
default action of following the current page's URL was not prevented. Also,
we don't need to use a NavLink component for the menu target when we are
not viewing a status page, because then the component won't need to be
highlighted anyways.

Discovered + fixed with the help of react-scan.

* fix(config): respect GOGC environment variable if no "runtime" block exists

Fixes: https://github.com/prometheus/prometheus/issues/16334
Related to:
- https://github.com/prometheus/prometheus/pull/15238
- https://github.com/prometheus/prometheus/pull/16052

Currently, when the GOGC environment variable is set -- and no `runtime`
block is set in the Prometheus config file -- it is ignored and the
default value of 75% is always used.

However, if there is an empty runtime block (e.g. `runtime: {}`), _then_
the GOGC environment variable is checked.

This PR changes this behavior to consistently check and use the GOGC
environment variable when it is set (unless the `gogc` field is set in
the `runtime` block of the loaded config file, in which case it still
gives that precedence).

* Clean up codeboxes and headings in docs

The new docs site will have syntax highlighting, so this adds language tags
to code boxes that are currently missing them. I didn't add `promql` as a
language yet since the highlighter doesn't support it yet, plus a lot of
the PromQL codeboxes in our docs aren't strictly valid PromQL, they are
more like multiple expressions listed in the same code box on multiple
lines. So I'm leaving that for sometime later.

In the HTTP API page, I moved the curl examples from the JSON codeboxes to
their own ones above the JSON output. I considered putting an "Output:"
text between the curl + JSON output, but I think the way it currently looks
without it is probably fine.

I also fixed a number of headings which were at the wrong level relative to
their nesting in the document.

I also removed `go` as a language from the Go template language examples,
because the Go template language isn't Go at all.

I also adjusted the indent on one codebox to be more reasonable (2 spaces
instead of 8).

And then finally, my editor made a bunch of whitespace changes
automatically, like removing trailing spaces.

* Add health & text filtering on the /rules page

Addresses part of https://github.com/prometheus/prometheus/issues/16515

For now, I'm adding very similar filtering to the /rules page as we have on
the /alerts page, with the difference being:

* The state filter filters by rule health (ok/warn/unknown) instead of
  alert state (firing/pending/inactive)
* We don't collect & show detailed stats on the different state counts as
  we do on the /alerts page

There is a lot of copied / very similar code between those two pages (and
also some others) around filtering and pagination, so maybe there is an
opportunity for more code sharing in the future here.

* fix(promql): histogram_count inconsistent

The problem is in the counter reset detection. The code that loads the
samples is matrixIterSlice which uses the typed Buffer iterator, which
will preload the integer histogram samples, however the last sample is
always(!) loaded as a float histogram sample in matrixIterSlice and the
optimized iterator fails to detect counter resets in that case.

Also the iterator does not reset lastH, lastFH properly.

This was an oversight because the old tests still happened to pass

In the past, we also applied different strategies to adjust the test

45s). This commit unifies things and reduces redundancy.

convoluted. ISTM the correct logic is to walk the path backwards to the

* Enhancement: Reload all scrape pools concurrently (#16595)

* Reload all scrape pools concurrently

At the moment all scrape pools that need to be reloaded are reloaded one by one. While reloads are ongoing mtxScrape is locked.
For each pool that's being reloaded we need to wait until all targets are updated.
This whole process can take a while and the more scrape pools to reload the longer.
At the same time all pools are independent and there's no real reason to do them one-by-one.
Reload each pool in a seperate goroutine so we finish config reload as ASAP as possible and unlock the mtxScrape.

These tests fail on darwin/arm64.

One is expected, because the test demonstrates the limits of the
numerical accuracy of our methods, and different inaccurate outcomes
on different hardware are expected.

The other two are mysterious at the moment, see

* promql: Fix unary operator precedence in duration expressions

Split unary operator handling in duration expressions into two specific

- Handle unary operators with number literals directly
- Handle unary operators with parenthesized expressions separately

This prevents unary minus from incorrectly binding to subsequent
operators in expressions like `foo offset -1^1`, ensuring it parses
as `(foo offset -1) ^ 1` rather than `foo offset (-1^1)`.

* fix(promql): histogram_quantile and histogram_fraction NaN observed in native histogram (#16724)

* fix(promql): histogram_quantile NaN observed in native histogram

Fixes: #16578

See the issue for detailed explanation.
When a histogram had only NaN observations and no normal observations,
we returned 0 from the quantile, which is completely wrong. If there were
normal observations but we went over them, we returned the upper bound of
the existing buckets, however that contradicts expectations on
histogram_fraction. Now we return NaN if the quantile is calculated to be
over all normal observations, falling into NaNs (in a virtual +Inf bucket).

We also return info level annotations if we see any NaN observations.
The annotation calls out if we returned NaN or even if we took the
virtual +Inf bucket into account.

This commit brings back direct mean calculation (for `avg` and

improved incremental mean calculation and features generally a bit
cleaner code than before.

Also, this commit...

- ...updates the lengthy comment explaining the whole situation and
  trade-offs.

- ...divides the running sum and the Kahan compensation term
  separately (in direct mean calculation) to avoid the (unlikely)
  possibility that sum and Kahan compensation together ovorflow
  float64.

- ...uncomments the tests that should now work again on darwin/arm64.

- ...uncomments the test that should now reliably yield the
  (inaccurate) value 0 on all hardware platforms. Also, the test
  description has been updated accordingly.

- ...adds avg_over_time tests for zero and one sample in the range.

This is being done because we've noticed a problem in the spec that could

to the scope. They would collide with the already reserved labels
otel_scope_name, otel_scope_version and otel_scope_schema_url.
