0f5a56c958 Stop using string keys in contexts
This fixes the OriginalIP and RequestUserID in the main featurebase
package, and the Access and Refresh tokens, the UserInfo, and the
[]string of Indexes passed with context.Context(s) in the authn package.

An empty struct was used for all of these keys (and relevant helper
functions we added) to avoid allocations where possible while still
using the context functionality.

Some of the logic in the server.GetIndexes function was fixed.

fff9ddc1f5 drop anti-entropy feature, since it doesn't work
The anti-entropy feature has never actually worked. We've been
talking about removing it or replacing it for ages, but haven't
had a concrete motivation.

But the anti-entropy interface is the sole user of several components
of the Tx interface, and now that we're trying to replace that
interface, being able to drop those components has some appeal, so
let's remove the one thing that used them, in the hopes that this
will simplify life.

This also lets us drop ForEach and ForEachRange, which were
barely used at all. The one surviving usage (CSV export) can be
handled by using the container iterator we already have, and
making ContainerCallback exported so we can use it to just call
things for every bit.

16ccbc461a Drop the ingest subpackage and related endpoints.
The internal/ingest and internal/schema endpoints were developed with
intent that they'd be the primary interface new users would work with,
because they were Easy To Use, and did not require any kind of setup,
the counterpoint being that ingest done this way had performance issues
because it ended up with huge amounts of JSON parsing to reformat
things into our native format. But this was understood to be the price
of providing a new-user-friendly JSON ingest experience.

A year later, we have no evidence that it's ever been used. We never
even moved it out of the `/internal` path. It's a lot of very complex
fiddly code and we don't seem to be using it, and at this point, our
anticipation is that if we really need something, we'll use CSV, which
we already have working, or something in the new SQL code. Either way,
we don't seem to be using this.

164dec1703 stop ignoring degraded/down states
We think etcd's tendency to mistakenly mark nodes down may have
been addressed. We can't find out without checking for it.

The exact pool of methods in methodsDegraded may have bitrotted
some; for instance, it didn't have PastQueries or PartitionNodes
in it, but it looks like it reasonably should.

We rework the Replica1/Replica2 server tests to reflect the
intended semantics again.

52d3329434 drop Starting cluster state
The special case of Starting allowed us to make sure every node in a
cluster waited for the whole cluster to come up, but caused problems
later if a node died and came back. We drop the Starting state for
clusters, treating a STARTING node as equivalent to an UNKNOWN (or
DOWN) node for purposes of cluster state, so clusters will go from
Down to Degraded to Normal as nodes come up. We now wait for the
Normal state during initial bringup. We would previously have accepted
Degraded, if you could reach it, for instance if a node came up and
then went down again before another node finished starting, but I'm
pretty sure that was unintentional.

This solves a problem where while a node was down, we'd accept
queries that we could handle in a degraded state, but then we'd
*stop* accepting them when the node started coming back up.

Batch insert via SQL (multiple tuples) (#2243)
* Formatting adjustments made during code review.

While reviewing the BULK INSERT logic (in order to decide how best to
approach "ingest via sql" in the cloud), I made a few formatting and
comment changes. I'm just adding them here as a separate commit so they
don't muddy up my actual work.

* Parser modifications to support mulitple tuples in INSERT INTO

This commit doesn't include all of the changes required in the
planner. Fow now, the planner is simply modified to continue supporting
a single tuple (the first tuple in the list).

* Update the planner to handle multiple INSERT INTO tuples

This is part 1. It's still using the existing logic which builds an
ImportRequest for every record (and every field!).

The next step will involve using a client.Batch to handle the records.

* Introduce client.Importer interface (used by client.Batch)

Instead of the Batch having a pointer to a client, this puts an
interface there instead (which the client implements). It also allows us
to inject a different importer (i.e. other than a featurebase.client)
into the Batch.

* Decouple batch from client

This commit pulls batch-specific code out of the client package and into
a new batch package. It introduces the batch.Importer interface, the
methods of which replace all the calls that batch was previously making
directly to client methods.

Finally, it contains two implementations of the batch.Importer
interface: one is a wrapper around client, and the other is a wrapper
around featurebase.API.

* Use docker (instead of MustRunCluster) for internal batch tests

Because the `batch` package tests are internal, using
test.MustRunCluster() resulted in an import loop (because it eventually
imports `server`, and we can't have that). So this commit replaces the
use of `test.MustRunCluster()` with docker. The setup is basically the
same as that used in the idk docker tests.

Here we also remove all client-side references to `UseIngestAPI`, which
is an experimental (json) ingest api. It's still suppored on the server,
but here we remove the external usage of it.

* cherry-pick fix

* Use batch.Import() for sql3 INSERT INTO statements

* Thread logger into sql3

cf94181c89 significant refactor of test setup and teardown
We centralize the creation paths for test indexes, fields,
etcetera so they all have a common path, all using standard
test holders. There's still two versions, one for test.* functions
and one for internal. They do share a TestHolderConfig though.

Large hunks of the related APIs are simplified/streamlined.
* Fragments are always created with a Field and don't need
  a workaround in case they don't have it.
* Creation of test fragments, etc., use optional FieldOptions
  but don't specify names because they're all using new holders
  for each thing created anyway. This dramatically reduces
  the complexity of the calls.
* test fragments are created inside test views which are created
  inside test fields, etcetera, so everything is using the same
  logic; test views aren't bypassing the other layers, they're
  creating themselves normally within a field.
* Quite a few things now use the standard runtime/production
  logic instead of being custom workarounds; for instance, instead
  of `mustOpenMutexFragment` creating a fragment and then creating
  a mutex vector for it, we just create a mutex-typed field and
  have the normal runtime code do this.
* Similarly, we now use the same field creation logic that production
  does, instead of having our own test-only thing that validates
  field names directly, so our test that we're validating field names
  is actually testing the runtime code. Yay.
* fragSpec goes away. it was a replacement for fragProxy which existed
  to solve memory allocation problems but replaced them with interface
  overhead problems. Now we just have pointers to things and maintain
  valid data structures.
* Many panics are now Fatal or Fatalf calls.
* Some specific bugs fixed, like a cluster which was requested and
  then had its first node directly overwritten, which isn't valid with
  shared clusters.
* Drop the temp-dir test flag and TempDir variable, we can just use
  $TMPDIR.
* Drop a benchmark of "write file to disk" that was purely a benchmark
  of file write speed, not a benchmark of rendering the data that needs
  to be written.
* Drop the unused "flags" parameter to fragment creation, which was
  only used back when we changed the BSI format.
* Use holder.Txf() rather than index.Txf(). The TxFactory has to be
  holder-level anyway, referring to it via the index is misleading.
* Test holders automatically close themselves and delete themselves,
  we remove various other things that thought they were responsible
  for deleting themselves.

added /sql endpoint; implemented SHOW TABLES (#1935)
* squashed 45 commits into one :)

* tlt/sql experiment (#2035)

* Move PlanOperator to sql3/planner/types package

includes:
type PlanOperatorColumn struct
type PlanOperator interface

* Remove planner dependencies from pilosa package

The goal after this is to prevent the planner package (which doesn't exist yet)
from being imported by the pilosa package; we just want it injected into the server
in server/server.go. This is because the planner package uses pilosa types, so we need
to avoid circular dependencies.

Added ExecutionPlannerFn
Make public: pilosa.ExecOptions
Added a pilosa.Executor interface
Added a planner.types.CompilePlanner interface
Isolated the planner calls to:
- Executor.Execute()
- *API.[method]()

* Move executionplanner files into the sql3/planner package.

This required a bit of gymnastics, and there are some things around
FieldOptions which need to be addressed soon.

* Remove the hacky FieldOptions stuff I added earlier

This implementation just uses the pilosa.FieldOption functional options
provided by the API (as opposed to trying to build a FieldOptions
object.

It also changes field types to constants. These are private for now, but
if we need to make them public, we should put them in the planner/types
package.

* Implement the "scale" value from Decimal(scale)

Also, precision and scale were currently reversed in the parser. This
fixes that.

* Modify the parser to handle CACHETYPE <type> SIZE <size>

It's a little odd to me that the cache type values are Tokens, but I
guess it's ok. One thing to keep in mind is that FeatureBase expects
lowercase values, so this commit changes the parser to set the value to
the lowercase version of the type.

* Fix the /sql2 tests

This entailed a combination of commenting out or t.Skip()-ing tests
which covered code in the parser that has been commented out or removed
as not currently supported in sql3.

It also adds some coverage for the sql.Contraint stringers.

* Prevent JSON sql results from containing closing commas

This commit just re-works the existing output code to avoid inserting
closing commas (which results in invalid JSON).

* Enhance the CREATE TABLE test coverage.

In particular, ensure that the fields which get created in FeatureBase
are what we expect based on the fields defined in the CREATE TABLE
statement.

This also ensures that the TIMEQUANTUM and CACHETYPE contraints are not
provided for the same field (since those constraints are not supported
together).

* Adjust the EBNF file to indicate SIZE contraint is optional

A CACHETYPE can be provided without a SIZE. This change indicates that
SIZE is optional.

* Remove `executionplanner_` from file names (#2040)

* implementation of ALTER TABLE (sans column RENAME)

* refactored expression analysis; added more robust type checking; all unary and bin ops function on ints

* added type support for expressions; full bin/unary op support; added cast; more literal support

* cast int to all other types

* all literals (except idset, stringset & timestamp) make it thru; cast to all types with int as source now works

* implemented LIKE/NOT LIKE

* Implemented IS [NOT] NULL

* Move sql2 files into sql3/parser package (#2045)

* Move sql2 files into sql3/parser package

This also removes the sql2 package.

* Fix tests which were typing _id fields as INT intead of ID

* implemented BETWEEN, NOT BETWEEN

* Add featurebase/error package (#2046)

* Add featurebase/error package

I copied the `dax/errors` package which I am starting to use in the DAX
prototype into `featurebase/errors` in order to start using it with the
sql3 package. It's basically a wrapper around `github.com/pkg/errors`,
but it uses a customer coded error.

The sql package can define its own errors based on the
`featurebase/errors` types. Then do things like `Wrap()` and `Is()`.

* Address the linter complaints: shadowed variables, unreachable code

* implemented IN & NOT IN with expression lists

* first cut of CASE

* Fixed some errors from rebase

* updated bnf; removed unused code; tightened up error handling

* first crack at basic CLI for SQL3

Use: `featurebase cli`

Still lots to do here, but for example:

> select count(*) from tremor
+--------------+
|        COUNT |
+--------------+
| 1.158321e+06 |
+--------------+

* Iterate on the CLI (#2057)

Handle the errors.
Add an "exit" command.
Add some general formatting and white space.

Add termination character: ";" (semicolon)

This commit allows a user to provide multiple or partial SQL statements.

Example of multiple statements:
```
show tables; select * from foo;
```

Example of partial (multi-line) statements:
```
select *
from foo;
```

Don't uppercase the header values

* error refactoring; first cut of TOP; remove unused code; use log.Printf instead of fmt.Printf

* fixed a bug with QualifiedRef from refactoring; added bones of INSERT; removal of unused code; tightened up errors more; fixed failing tests

* single value list for INSERT

* Update bnf per discussion with Travis; INSERT now doing the requisite stuff

* Pat's eyes went square - nothing wrong with TOP, Pat needed to learn arrays again.

* improved some errors; fixed tests to suit

* send warnings back in the api; update CLI to display warnings

* start warning on stuff not implemented so we don't get bugged about it

* Tlt/sql experiment (#2063)

* Expresssion -> Expression

* Add SQL planner test

- adds a test to which it is easier to add tables and SQL statments
- un-exports all of the expression types
- removes the planner pointer from the expression types (it can be added
  back later if need be)

* Fix where clause on a string field

Prior to this commit, the binary expression for a where clause on a
string field was building the call by providing a range operator which
is typically used for BSI fields. This changes it to use the call.Args
for string values.

* Update planner tests to handle multiple sql for the same results

* Reorganize SQL tests

Introduce a test/helpers package and move shared MustQueryRows into that
package.

* Add a compatibility map for field types. (#2064)

This is primarily to address the fact that ID fields were previously
incompatible with INT literals.

We should probably consider introducing a custom type for FieldType
which can be used to define compatibilities.

* significantly refactored type checking

* Handle nil (NULL) values in the sql CLI. (#2067)

go-pretty panics if the interface{} field value is nil. This replaces
nil values with a "NULL" string.

* Squash some commits

fixed a still failing test

added line, col to all error messages

refactored source handling to enable table aliases

fixed some copypasta per review

warnings for order by & topn; implemented select as a source

starting to handle in (select...); added stub for optimizer

JSON-encode the sql error and warning strings (#2069)

Error strings with unencoded characters (like double quotes) were
resulting in invalid json.

got insert working; added symbol table; added concrete optimizer; added nascent NestedLoopsOperator; rewrite "where foo in (select..." as inner join

* all about the sets (#2085)

* implemented setcontains()

* implemented set literal; insert set column values; setcontains/all/any both in expr eval and pql filters

* Convert test to use latest framework. (#2086)

* dates (#2094)

* return dates as strings in output; tightened up decimal type checking

* return dates as strings in output; tightened up decimal type checking

* fixed failing tests after decimal changes

* can now insert decimal values

* implemented insert for timestamp data type; implemented current_date, current_timestamp constants

* fixed some failing tests

* handle date literals from strings in insert statements

* changes from feedback

* Fix pointer method error

* sql3 API interface (#2110)

* Introduce API-related interfaces: SchemaAPI, ComputeAPI

The sql3 code was relying on the pointer: *pilosa.API in order to call
API methods directly on the local node. If we want to import and use the
sql3 package in another service (the DAX queryer, for example), we need
to be able to use an implementation of an interface for those API method
calls.

This commit introduces two interfaces, both automatically implemented by
pilosa.API:
- SchemaAPI
- ComputeAPI

* Convert sql3 code to use IndexInfo instead of Index

The sql3 code was relying on a *pilosa.Index and its methods to get
general information like index and field name, type, etc. This commit
converts everything to use a *pilosa.IndexInfo instead.

This allows us to modify the SchemaAPI interface to also return
IndexInfo instead of Index, which will be a lot easier to implement in a
non-pilosa package (like DAX); creating a *pilosa.Index requires
providing things like data directory paths and holders, which are not
necessary for these use cases.

* Unary and Binary Ops R US plus CAST (#2111)

* implemented string literal for timestamp epoch

* fixed failing test

* fixed the failing test again

* refactored tests; implemented unary op tests for all datatypes; implemented binop tests for int/int, int/id, int/decimal & ID/int

* implemented all binary ops for INT & all other types, ID & all other types

* implemented binary ops for DECIMAL types & all other types

* added STRING & BOOL to various tests; implemented all remaining binOp tests

* fix up some stuff after rebasing

* refactored test defs into multiple files; implemented CAST for every datatype

* added tests for like/not like

* addressed review feedback

* addressed type review feedback

* tightened up IS [NOT] NULL behavior plus tests (#2118)

* tightened up IS [NOT] NULL behavior plus tests

* BETWEEN/NOT BETWEEN with all data types

* addressed review feedback

* Handle negative integers in column min/max constraints (#2120)

This commit parses the min/max contraint as an expression, as opposed to
an int literal, so that negative values are treated as Unary
expressions.

There currently isn't support for min/max constraints on `decimal`
fiels, so for now this change only expects +/- integer values.

* Implement the CREATE TABLE keypartitions logic (#2123)

* Execution time, IN/NOT IN & multiple aggregates (#2124)

* added display of execution time

* IN/NOT IN tests for all data types

* fixed date parsing

* removed duplicative tests

* refactoring aggregates

* suport multiple aggregates

* Address review feedback

* final round of feedback

* Add method SchemaAPI.CreateIndexAndFields() (#2127)

In order to support a CREATE TABLE statement as a single command, this
commit alters the SchemaAPI interface to contain a single method which
handles both the index and its fields. It also updates the sql3 code to
use this interface instead of CreateIndex() and CreateField()
indepedently.

* Symbol Handling (Again) (#2129)

* Refactored symbol handling in the planner; re-instated the select as source tests

* removed commented out code

* addressing review feedback

* Move hard-coded _id field out of planner and into interface implementation (#2130)

This commit moves the hard-coded addition of the `_id` field from the
planner to the SchemaAPI.IndexInfo() implementation method.

NOTE: If anything was expecting SchemaAPI.Schema() to also return the
`_id` field as part of its field list in each table, then it would not
be there because the `_id` field is only added in the IndexInfo() method
for now. Currently that's not a problem because nothing is expecting the
`_id` field for `Schema()`.

* Multiple aggregates, all aggregates stand alone and in GROUP BY (#2132)

* handle multiple aggregates in group by queries

* added handling for avg() aggregate both stand alone and in group by

* tightened up sum & avg outside of group by

* added min, max & percentile

* added warnings

* Make MaterializedRowSet implement the PlanOperator interface. (#2133)

This commit refactors the PQLMultiGroupByOperator to have a PlanOperator
as its output. Then, when it initializes, it sets up a
MaterializedRowSet and populates that with the values from the multiple
group by operations.

* added explicit min/max pql operators

* saved a file I forgot to save

* per review

* Un-indent some if/else nesting (#2136)

Co-authored-by: Travis Turner <travis@pilosa.com>

* Add optional `name` argument to test structs.

This commit adds the `name` argument to `tableTest` and `sqlTest` so
that a test can be optionally named. This allows a developer to more
easily run/identify a particular test by name.

* Inbuilt functions (redux) (#2141)

* set functions type parameter type checking

* implemented datepart

* include SQL3 type in SHOW COLUMNS output

* fixed select as source; failing SHOW COLUMNS test

* select in select list

* dump output columns; handle optimization for select list subqueries

* make it an error to return multiple rows for a select list subquery

* added description

* contants and test coverage for datepart function

* SQL3 Refactor-palooza (#2182)

* removed unneeded IsAggregate()

* first cut of working nested loops operator aka INNER JOIN

* remove selectListItemPlanExpression

* added some warnings

* all the tests are passing again!

* addressed some linter complaints

* added basic order by

* bug fixes; added 'or replace'/'replace' to insert

* for insert references should return appropriately

* added back ability to use subquery singleton expressions

* removed dead code; fixed test

* json-able plan, Schema() plus refactoring

* fixed dumb code

* add some tests for time quantum behavior

* Code cleanup during review. Also fixed INSERT to keyed table bug.

This commit contains a lot of minor adjustments made during code review.

It also contains a bug fix that was preventing INSERT into a keyed table
(i.e. _id type STRING) from working.

* Fix expected min/max on timestamp column test (decimal field)

I don't know why this changed, but presumably something to do with
decimal related work that happened on master.

[FB-1024 FB-1590] Increase timerange (un-revert) (#2174)
previously we allowed users to specify a granularity for timestamp
e.g. seconds, milli, micro, nano
however we converted everything to nano before we stored it.
This reduced the allowed range for all time units to what
was allowed by timestamp. For example, with second granularity
you can represent billions of years within the capacity of
int64 but with nano its somewhere b/w 100-200 years.

So now, for timeunits of seconds, milli, and micro the range
is year 0001 - 9999. These limits come from what Go
supports.

So this uses unit specific function to translate
timestamps to values and vice versa to increase
the time range.

In the process of increasing the range for timestamp and subsequent
testing, I found and addressed a few bugs:
- min/max queries were not using timestamp specific comparators so
  added that.
- Values from Import/ingest come to FB as relative values to epoch
    whereas other BSI fields come as actual values and then
    becomes relative to their respective bases within FB. so some
    specific handling of that was added.
- However! Set queries use timestamp strings which are, of course,
    the actual value they designate. So they have to become
    relative.
- When bitdepth is 0, Min/maxUnsigned functions did not run
resulting in a count of 0 when there
was an actual value that was 0.

Also, this removes (now) dead code and updates/adds tests.

b3a4e52a13 simplify, streamline, and possibly debug embedded etcd
The root problem this is attempting to address is sporadic
weird cases in which etcd mistakenly thinks it's down even when
it's up. I am not confident that this is addressed, but there's
a reasonable chance that it is, and I can't trigger it at the
moment, but it was always sporadic, so that doesn't prove much.

There's a lot going on here, and it comes into roughly three
categories.

First: Dropping unused/unneeded code. There's a lot of leftover
bits from the initial development and refactoring of this.

Second: Unifying and shuffling some of the design. We had
multiple interfaces which are functionally impossible to
usefully implement separately, so they're combined together,
and in some cases, moved.

Third: Streamlining logic and simplifying design choices.

This is combined into one commit because the changes are
thoroughly entertwined with each other and you can't usefully
break most of them out.

Also, a bunch of test coverage for most of these changes.

Big changes:

We merge the topology and disco packages.  The topology and disco
packages being separate creates a complicated tangle of problems
and dependencies.  The fundamental problem, approximately, is that
topology.Node has to track disco.NodeState.

There's three core interfaces interacting here:
	topology.Noder (maintains list of nodes)
	disco.Stator (maintains the state of a node)
	disco.Metadator (stores, possibly retrieves, node metadata)
But the node state mantained by the Noder *is* the set of node
metadata, plus state updates produced by Stators. The only actual
non-trivial and usable implementation of these interfaces is a single
thing which implements all three, and in which the implementations
share a single backend data source which they are all modifying.

But you can't move Noder into disco, because Noder has to refer
to topology.Node, but topology.Node refers to disco.

Solution: First, merge these two packages. Second, merge these
three interfaces, to provide a single interface which is more
clear about the fact that (metadator.)SetMetadata() and
(stator.)Started() are both changing the output we'll get from
(noder.)Nodes().

We rework the node state tracking.

We have this nodeStates map which is almost unused. Really, we
don't need it at all. Every node's state is either its last heartbeat
state or "Unknown", so we simplify this a bit. Also, we ensure that
the populateNodeStates function itself is yielding the sorted nodes
list, so we don't have to be as worried about possible later lookups
of sortedNodes happening outside a lock. We also add diagnostics
for deleting nodes from the metadata list (this should never happen),
and try to track heartbeat state more closely.

This is *probably* what fixes the underlying reported problem,
if anything did.

Still an open issue: Make heartbeat state changes aware of when
they're talking about *this* node and possibly not try to
mark it down? Except this may have a flaw: That would result in
each node disagreeing with other nodes in etcd about the state
of that node in the failure cases, and undermine the point of
using etcd to keep these states consistent.

We reduce the number of contexts and cancelfuncs in the etcd wrapper.

We create a shared context for the non-etcd.embed children of our
etcd wrapper, the heartbeat/keepalive and the node watcher, so we
can cancel that one context and cancel all of those at once, so
we don't need to separately track a function to call to cancel
the watch, AND be closing another channel. Also, our shutdown
now propagates automatically to the various etcd API calls we've
made for things like the node watcher and keepalive calls.

We still need to watch that channel in watchNodesOnce, though,
because apparently the watch doesn't yield an error even if the
context calling it is canceled. Whee.

This should reduce the risk of ending up in an inconsistent state,
and also the Close() function is probably idempotent now.

Smaller changes:

* Remove config-generators that existed to generate etcd
  configs but were used only for tests that no longer exist
  or make sense.
* Move the logic to generate etcd configs into the etcd
  package, instead of the "testing" subpackage. This allows
  us to write a self-contained config generator for
  clusters where the nodes know about each other, but do
  this just with etcd, not with full featurebase servers.
* Move the thing generating `fake:%d` socket names into
  the etcd package, which is the only place we use it.
  Also simplify it slightly.
* Don't panic on invalid URLs, report errors from them.
* At least try to use etcd's config.Validate functionality.
  It's underdocumented, so we're not sure what it will report,
  but at least if it does we'll get reports from it and
  know what they are?
* Try to handle CompactRevision errors from watches more
  correctly -- after a CompactRevision, any future attempt
  to watch from a lower revision will necessarily fail, so
  we adjust our target revision up. We don't have good
  testing for this.
* Drop the Metadata() method (that used to be in Metadator)
  because nothing ever used it and it didn't make much sense
  to try.
* Convert SetMetadata from taking an arbitrary json blob
  to taking the only data that would ever be valid since
  we always use it to extract node information anyway.
* Drop several unused functions, unexport things only used
  internally.
* Replace Started() with SetState("STARTED"), allowing us
  to write tests that mess with states. We weren't really thinking
  carefully about state transitions sometimes and now it's much
  easier to do that thinking.
* Stop leaving stray localhost:2380 and localhost:2379 in
  our embed config. We still sometimes see peer requests from
  those and I honestly don't know why, but at least it should
  be rarer.

33a916c0f4 Revert "increase time range for timestamp by using specified granularity"
This PR reverts the timestamp work.

The timestamp work requires changes to FB and IDK; and there are
circular dependencies between tests in either repo preventing merging
of either. The work here is pretty stable, but required bypassing
the smoketest. Meanwhile, I found some additional things in IDK that
need addressing which means I merged this work in pre-maturely. Once
I get that worked out, I'll re-commit these commits.

This reverts following commits related to timestamp work:

33fce8a05b fix few bugs regarding timestamp
In the process of increasing the range for timestamp and subsequent
testing, I found and addressed a few bugs:
- min/max queries were not using timestamp specific comparators so
  added that.
- Values from Import/ingest come to FB as relative values to epoch
    whereas other BSI fields come as actual values and then
    becomes relative to their respective bases within FB. so some
    specific handling of that was added.
- However! Set queries use timestamp strings which are, of course,
    the actual value they designate. So they have to become
    relative.
- When bitdepth is 0, Min/maxUnsigned functions did not run
resulting in a count of 0 when there
was an actual value that was 0.

Also, this removes (now) dead code and updates/adds tests.

593992312a increase time range for timestamp by using specified granularity
previously we allowed users to specify a granularity for timestamp
e.g. seconds, milli, micro, nano
however we converted everything to nano before we stored it.
This reduced the allowed range for all time units to what
was allowed by timestamp. For example, with second granularity
you can represent billions of years within the capacity of
int64 but with nano its somewhere b/w 100-200 years.

So now, for timeunits of seconds, milli, and micro the range
is year 0001 - 9999. These limits come from what Go
supports.

So this uses unit specific function to translate
timestamps to values and vice versa to increase
the time range.

fd9d4de31d Remove most of the resize-related logic
We had two different, incompatible-with-each-other, and both
individually broken, partial implementations of resizing logic.
There's the original pre-etcd resize, and then the etcd resize,
and neither works, but there's conflicts between the ways they
don't work.

No attempt to fix this is likely to yield decent results, so
instead, we yank them both out entirely, so if we decide to
implement resizing (which we will) we won't be confused by
stray code pertaining to resizing that's not really hooked
up to anything.

We're leaving the resize messages in protobuf to avoid renumbering
protobuf messages. We rename some of our message types to UNUSED0,
etcetera, so that any code still using the old names won't
compile, to make sure we get rid of it, but we can't just drop
the numbers without breaking rolling restart.

The Resize_AddNode tests are removed not just because we don't
have resizing, but because they were completely broken anyway
and never worked at all. But there's no reason to fix them because
they exist to fix the functionality we didn't have and are now
removing the vestigial remains of.

We also drop the one usage of the AddNode function of Noder, because
it was used only by one test code fragment that was creatincg clusters,
and that can be done more correctly. There were no other call sites
at all.

We mark the monitorAntiEntropy function to be ignored by
code coverage because it's not actually being covered. There's
a separate ticket for removing that entirely.

772496b440 "all bitmap" multi-field, single-shard ingest
This adds a shard-based import endpoint which takes bitmap data for
all field types and imports data for the whole shard transactionally.

It uses the BitmapRewriter interface to try to intelligently allow for
setting and clearing bits simultaneously without multiple writes which
is especially helpful when ingesting into int-like fields, but also
allows clear-and-then-set behavior for set fields.

dee46d4423 add PartitionToNodeAssignment as a new option
We default to the jmp-hash method which we had previously, and allow a
user to set the "modulus" option which uses a simple mod operation to
ensure an even spread of partitions across nodes.

I think that ideally we would have new indexes uses modulus and
existing indexes use jmp-hash which implies supporting this
configuration on a per-index basis.

If we don't do per index, we should probably run the whole test suite
both ways.

dbc3159e2c TranslateData should only redirect to an up node
During backups on a multi-node cluster, TranslateData was unconditionally redirecting to the primary, regardless of the primary’s status. This is less than ideal. If the primary is down, the backup will fail.

As a consequence of this fix, we will also no longer needlessly redirect to ourselves on a single node cluster. This is a great optimization win!!!!

28c2ccf074 allow ingest API delete to work at all, add test for it
The ingest API tried to do a Qcx operation that needs a write Tx after
requesting a write Tx. This doesn't work. The ingest API is the only caller
of clearExistenceColumns, so it's easy to just make it work for a given
shard using a provided Tx. This isn't especially clean, but a lot of this
is due for an overhaul anyway because the Qcx/Tx stuff is sort of broken.

Also, add any test case at all for this, since we didn't have one, and
also fix the fact that the test case failed because the test harness
didn't allow empty result sets.

bc6947a9ac try not to deadlock on simultaneous CreateField to two nodes in a cluster
Two CreateField messages reaching different nodes in a cluster at the same
time could cause a deadlock because each CreateField runs with a write lock
held, then issues requests to other nodes which, at a minimum, need
a read lock and which may require a write lock. Reorder things a bit to
make the broadcast to other nodes happen outside the lock. We may also
need to do something to have nodes handle the case where something's been
created in etcd but they haven't gotten the message about it yet.

Stop blocking API called when cluster is DOWN or DEGRADED
This commit effectively removes the API-level validation that was
blocking certain API methods when the cluster was in a particular state
(namely DOWN and DEGRADED). The thinking is that we shouldn't be
blocking these requests at the API level, but rather should let them
pass through and allow the fact that a node is ACTUALLY down dictate the
behavior.

With this change, two tests were modified. They were previously
expecting the error message from the API validation on DOWN, but now
they check for a "shard unavailable" error, which is what gets returned
for a particular query when the cluster is in an unhealthy state.

ddb5020aa6 slightly better lock protection around bitDepth in view
There's a number of deeper issues here (the fragment is conjuring
up a Tx, for instance) but this helps.

Also use field.view() to get the view rather than accessing viewMap
directly without a lock. Also change field.cacheBitDepth to ratchet
upwards -- if we have multiple shards and some shards have lower
depths than others, we should use the highest as the cached value,
not the most recent.
