ArrayCursors were ignoring errors, which led to panics when nil
cursors were operated on. This fix passes errors back up the stack
and uses them to enforce healthy cursor creation.

* chore: add scaffolding for naive solution
* feat: test case scaffolding
* fix: implement check for series key before proceeding
* fix: add validation for ReadSeriesKeyMeasurement usage
* refactor: explicit use of series key len
* feat: add remaining check to index
* feat: add check to remaining files
As the Len function is used as part of the parseSeriesKey, this also needs to be accounted for on the nil return from this function as it is used in different contexts
* feat: expand test cases
* chore: go fmt
* chore: update test failure message
* chore: impl feedback on unnecessary sz checks
* feat: expand test cases
* fix: nil series key check
In both sections for index.go there is a pre-existing length check against the series key which should catch invalid values, perhaps this explains why it hasn't cropped up in the reported panics. For even more safety, we can also skip a nil key because we know that subsequent calls will cause a panic where this key is attempted to be used
* fix: remove nil tags check
A key with no tags is valid, so we should not check for BOTH nil key and tags as a key could be nil, which is invalid, yet still have tags and therefore cause the check to pass which we do not want
* feat: extend test cases from feedback
* fix: extend checks for CompareSeriesKeys
* feat: add nilKeyHandler for shared key checking logic
* fix: logical error in nilKeyHandler
Prior to this, the else was always defaulted to at the end of the conditional branch, which causes unexpected behaviour and a failure of a bunch of tests.
* fix: return tags keep nil data
In a recent change to this, we agreed on a simple name == nil check for the actual data. As a follow on to this, I just realised that we don't actually want to nil back the tags, even if they're not checked, because having no tags is a valid input so we can simply return whatever we were passed unchanged.
* fix: use len == 0 for extra safety
* feat: extra test for blank series key
Some series files which are smaller than the standard
sizes cause SIGBUS in influx_inspect and influxd, because
entry iteration walks onto mapped memory not backed by the
the file. Avoid walking off the end of the file while
iterating series entries in oddly sized files.

* chore: upgrade Go to 1.19.3
This re-runs ./generate.sh and ./checkfmt.sh to format and update
source code (this is primarily responsible for the huge diff.)
* fix: update tests to reflect sorting algorithm change
* feat: upgrade flux to 0.171.0
Tests failing, safety commit
First step in https://github.com/influxdata/influxdb/issues/23815
* fix: remove "org" parameter" from writeOptSource
I attempted to implement the "orgOpt" argument in a similar fashion
to f6669f7512. However, it looks like Flux doesn't accept "org" as
a parameter to "load". It responds with:
Error calling function \"load\" @113:16-113:30: error calling function \"to\" @6:19-6:47: unused arguments [org]
This brings us from 194 passing to 570 passing.
* fix: temporarily disable broken flux tests
These tests expect rows to be stored in a certain order. However,
nothing is specifying the sort order. This has been fixed in a
later update to flux: (see 3d6f47ded).
Temporarily disable these tests until we include a fixed
version of the flux tests.
* chore: add tests from a492993012
This fixes "test-flux.sh" so it runs tests within the "flux/"
directory. This uncovered some other issues with the tests
located within "flux/". These also needed to be updated
to match the newer flux API.
* feat: upgrade flux to 0.172.0
This includes changes made in "cbbf4b27da". Since "test.go" in 2.x
diverged from 1.x, some modifications were required to make this
compatible.
* feat: upgrade flux to 0.173.0
* feat: upgrade flux to v0.174.0
* fix: Update the condition when reseting cursor (#23522)
Filters that contain `or` may change between cursor resets so we must remember to update the condition in the read cursor.
```flux
|> filter(fn: (r) => ((r["_field"] == "field1" and r["_value"]==true) or (r["_field"] == "field2" and r["_value"] == false)))
```
Closes https://github.com/influxdata/flux/issues/4804
* feat: upgrade flux to 0.174.1
* feat: upgrade flux to 0.175.0
* chore: remove end-to-end tests
These were removed in a492993 for 2.x. These tests prevent "go test ./..."
from completing. As stated in the original commit, these tests should now be
handled by the "fluxtest" harness.
* feat: upgrade flux to 0.176.0
Some tests needed to be disabled within the flux harness. This is a
result of enabling "Optimize Aggregate Window" in flux@05a1065f.
These tests are not present in 2.x. Therefore, I am unsure if
the breakage is resolved in a later commit.
* feat: upgrade flux to 0.177.0
* feat: upgrade flux to 0.178.0
* feat: upgrade flux to v0.179.0
This removes all invocations of "flux.RegisterOpSpec". According
to flux@e39096d5, "flux.RegisterOpSpec" does nothing in the
current version of flux and was removed.
* chore: update fluxtest skip list (#23633)
* chore: manually backport 785a465e9a
This removes the reference to "flux.Spec".
* build(flux): update flux to v0.181.0 (#23682)
* build(flux): update flux to v0.184.2
* chore: skip more Flux acceptance tests
There are issues for each skip detailed in test-flux.sh.
* feat: upgrade flux to v0.185.0
This adds "FluxTesting" to the "HTTPD" configuration. This option is
hidden and disabled by default. When "FluxTesting" is set, it
enables the default testing flags for "Flux".
These flags allow the "vectorized float tests" and tests requiring
the "removeRedundantSortNodes" and "labelPolymorphism" flag
enabled to work. These changes are based off of d8553c002e.
flux@3d6f47ded is included within this version of Flux. Therefore
we can now include the "group_*" tests.
* feat: upgrade flux to 0.186.0
* feat: upgrade flux to 0.187.0
* feat: upgrade flux to 0.188.0
* fix: re-run ./generate.sh with updated protoc
* fix: restrict cores to match CircleCI documentation

* fix(restore): fix race condition which causes restore command to fail
Fixes a race condition in the restore code path that causes shard data restores
to fail. When the bug occurs, `Error while freeing cold shard resources`
appears in the log files.
fixes issue #15323
SHOW TAG KEYS FROM "foo" where bar="misquoted" is
erroneous, because the tag value must be enclosed
in single, not double, quotes. Although this
correctly returns no tag keys, it is very
inefficient and has cause out-of-memory failures
at a customer. This fix short-circuits the query.

If os.Link fails with syscall.ENOTSUP, then the file
system does not support links, and we must make copies
to snapshot files for backup. We also automatically make
copies instead of link on Windows, because although it
makes links, their semantics are different from Linux.
closes https://github.com/influxdata/influxdb/issues/16739
On Windows, make copies of files for snapshots, because
Go does not support the FILE_SHARE_DELETE flag which
allows files (and links) to be deleted while open. This
causes temporary directories to be left behind after
backups.

The tsmBatchKeyIterator discards excessive errors to avoid
out-of-memory crashes when compacting very corrupt files.
Any error beyond DefaultMaxSavedErrors (100) will be
discarded instead of appended to the error slice.
closes https://github.com/influxdata/influxdb/issues/22328
When the compaction planner runs, if it cannot acquire
a lock on the files it plans to compact, it returns a
nil list of compaction groups. This, in turn, sets the
engine statistics for compactions queues to zero,
which is incorrect. Instead, use the length of pending
files which would have been returned.
closes https://github.com/influxdata/influxdb/issues/22138
This fix ensures that memory-mapped files are not released
before pointers into them are copied into heap memory.
MeasurementNamesByExpr() and MeasurementNamesByPredicate() can
cause panics by copying memory from mmapped files that have been
released. The functions they call use iterators to files which
are closed (releasing the mmapped files) before the memory is
safely copied to the heap.

Compaction logging will generate intermediate information on
volume of data written and output files created, as well as

tsm1.DigestWithOptions closes its network connection
twice. This may cause broken pipe errors on concurrent
invocations of the same procedure, by closing a reused
i/o descriptor. This fix also captures errors from TSM
file closures, which were previously ignored.
Closes https://github.com/influxdata/influxdb/issues/21656
Under heavy write load creating new fields and measurements
the rewrite of the fields.idx file is a bottleneck. This
enhancement combines multiple writes into a single one and
shares any error return value with all of the combined
invocations. MeasurementFieldSet and the new
MeasurementFieldSetWriter must both now be explicitly
closed.
Closes#21577
tsdb.Engine.IsIdle and tsdb.Engine.Digest now return a reason string for why the engine & shard are not idle.
Callers can then use this string for logging, if desired. The returned reason does not allocate memory, so the
caller may want to add the shard ID and path for more information in the log. This is intended to be used in
calls from the anti-entropy service in Enterprise.

* fix: backport tsdb fix for window pushdowns
From https://github.com/influxdata/influxdb/pull/19855
* fix(storage): cursor requests are [start, stop] instead of [start, stop)
The cursors were previously [start, stop) to be consistent with how flux
requests data, but the underlying storage file store was [start, stop]
because that's how influxql read data. This reverts back the cursor
behavior so that it is now [start, stop] everywhere and the conversion
from [start, stop) to [start, stop] is performed when doing the cursor
request to get the next cursor.

The anti-entropy service will loop trying to copy an empty shard to a

of that directory, instead of to the Unix epoch.

This is a backport of #14262 to the 1.x storage engine.
This also ports the table tests that existed with the pre-beta version of the
storage engine to the one that is now used in the production version.
A few of the tests are skipped. These are portions of the storage engine
that have not been ported over. They should be unskipped when that
functionality is ported over.

* feat: add cursors and readers for window aggregates
* fix: backport fix + tests for race condition in flux tag cache
* test: port 2.x test for array_cursor
This fixes multi measurement queries that go through the storage service
to correctly pick up all series that apply with the filter. Previously,
negative queries such as `!=`, `!~`, and predicates attempting to match
empty tags did not work correctly with the storage service when multiple
measurements or `OR` conditions were included.
This was because these predicates would be categorized as "multiple
measurements" and then it would attempt to use the field keys iterator
to find the fields for each measurement. The meta queries for these did
not correctly account for negative equality operators or empty tags when
finding appropriate measurements and those could not be changed because
it would cause a breaking change to influxql too.
This modifies the storage service to use new methods that correctly
account for the above situations rather than the field keys iterator.
Some queries that appeared to be single measurement queries also get
considered as multiple measurement queries. Any query with an `OR`
condition will be considered a multiple measurement query.
This bug did not apply to single measurement queries where one
measurement was selected and all of the logical operators were `AND`
values. This is because it used a different code path that correctly
handled these situations.
Backport of #19566.

* fix: Change from RewriteExpr to PartitionExpr
Also remove some dead code
* feat: WITH KEY implementation
* feat: query rewriting for WITH KEY in SHOW TAG KEYS
Meta queries (SHOW TAG VALUES, SHOW TAG KEYS, SHOW SERIES CARDINALITY, etc.) do not respect
the QueryTimeout config parameter. Meta queries should check the query context when possible
to allow cancellation and timeout. This will not be as frequent as regular queries, which
use iterators, because meta queries return data in batches.
Add a context.Context to
(*Store).MeasurementNames()
(*Store).MeasurementsCardinality()
(*Store).SeriesCardinality()
(*Store).TagValues()
(*Store).TagKeys()
(*Store).SeriesSketches()
(*Store).MeasurementsSketches()
which is tested for timeout or cancellation
to allow limitation of time spent in meta queries
https://github.com/influxdata/influxdb/issues/20736
* feat(query): hyper log log counting in query engine
In addition to helping with normal queries, this can improve the 'SHOW CARDINALITY'
meta-queries:
time influx -database mydb -execute 'select count_hll(sum_hll(_seriesKey)) from big'
name: big
time count_hll
---- ---------
0 200767781
influx -database mydb -execute 0.06s user 0.12s system 0% cpu 8:49.99 total
Extending the context instead of fixing the API breaks type safety.
For tracking the number of points / values written, it is much clearer
to pass an explicit tracker.
When using queries like 'select count(_seriesKey) from bigmeasurement`, we
should iterate over the tsi structures to serve the query instead of loading
all the series into memory up front.
Closes#20543
fields.idx frequent writes cause lock contention and fields.idx is recreated
when a field or measurement is added in a WritePointsWithContext()
This eliminates locking during the actual file rewrite, and limits it to
the times when the MeasurementFieldSet is actually being read or written
in memory and when the new file is being renamed.
Test verification of correct behavior by checking the fields.idx
file matches the in-memory copy after heavily parallel measurement addition.
Fixes https://github.com/influxdata/influxdb/issues/20500
When a SELECT INTO query generates an illegal value that cannot be inserted,
like +/- Inf, it should return an error, rather than failing silently.
This adds a boolean parameter to the [data] section of influxdb.conf:

When false, the default, the old behavior is preserved. When true,
unsupported values will return an error from SELECT INTO queries

https://github.com/influxdata/plutonium/issues/3227
When an InfluxDB database is very busy writing new points the backup
the process can fail because it can not write a new snapshot.
The error is: operation timed out with error: create snapshot: snapshot in progress.
This happens because InfluxDB takes almost "continuously" a snapshot
from the cache caused by the high number of points ingested.
The fix for this was https://github.com/influxdata/influxdb/pull/16627
but it was for OSS only, and was not in the code path for backups
in clusters.

This feature allows compaction to be disabled on a per-shard basis by
creating a file named do_not_compact in a shard's directory. When
disabled, a message is logged every 15 minutes with the reason for
compaction being disabled (existance of the file). This makes it easy to
know if compaction has been disabled for any shards by searching the log
for "compaction disabled" or running "find path/to/data -type f -name
do_not_compact".
