Fixes#5233 by removing `EconomicMap` & co. and using plain old good _linear hashing_. Fixes#8090 by introducing `StorageEntry.removed()` rather than copying the builder on each removal.
- Closes#5303
- Refactors `JoinStrategy` allowing us to 'stack' join strategies on top of each other (to some extent) - currently a `HashJoin` can be followed by another join strategy (currently `SortJoin`)
- Adds benchmarks for join
- Due to limitations of the sorting approach this will still not be as fast as possible for cases where there is more than 1 `Between` condition in a single query - trying to demonstrate that in benchmarks.
- We can replace sorting by d-dimensional [RangeTrees](https://en.wikipedia.org/wiki/Range_tree) to get `O((n + m) log^d n + k)` performance (where `n` and `m` are sizes of joined tables, `d` is the amount of `Between` conditions used in the query and `k` is the result set size).
- Follow up ticket for consideration later:
#8216
- Closes#8215
- After all, it turned out that `TreeSet` was problematic (because of not enough flexibility with duplicate key handling), so the simplest solution was to immediately implement this sub-task.
- Closes#8204
- Unrelated, but I ran into this here: adds type checks to other arguments of `set`.
- Before, putting in a Column as `new_name` (i.e. mistakenly messing up the order of arguments), lead to a hard to understand `Method `if_then_else` of type Column could not be found.`, instead now it would file with type error 'expected Text got Column`.
- Sets the default limit for `Table.read` in Database to be max 1000 rows.
- The limit for in-memory compatible API still defaults to `Nothing`.
- Adds a warning if there are more rows than limit.
- Enables a few unrelated asserts.

Added Blank_Selector constructor and applied to remove_blank_columns, select_blank_columns, filter_blank_rows for #7931 . Changed when_any to when for readability.
Previously, constant columns were given generated names with UUIDs in them, which are long and provide no information. Instead, we now use the constant value itself to form the name.
Since these new generated names are less unique, we must explicitly make them unique, in cases where the caller did not explicilty set a name.
- Closes#7981
- Adds a `RUNTIME_ERROR` operation into the DB dialect, that may be used to 'crash' a query if a condition is met - used to validate if `lookup_and_replace` invariants are still satisfied when the query is materialized.
- Removes old `Table_Helpers.is_table` and `same_backend` checks, in favour of the new way of checking this that relies on `Table.from` conversions, and is much simpler to use and also more robust.
- Fixes#8049
- Adds tests for handling of Date_Time upload/download in Postgres.
- Adds tests for edge cases of handling of Decimal and Binary types in Postgres.
- Fixes issue with `to_display_text` on `Date_Time`. Now a reversible format.
- Adjusted the auto width code on table so it works.
- Manually sized columns should remain fixed size.
- Enable Excel range style selection in table.
- Removed page support as not implemented yet.
# Important Notes
Will need to apply to Vue based viz at some point as well.
- Adds the ability to use numbers, date/time and Boolean values as constants in `set`.
- `Table.set` can take a `Column_Operation`, allowing for deriving of a new column based on other columns.
- Added `Column_Ref` type to refer to a column in `filter`.
- Fixes a bug where creating a temporary table could accidentally issue a `DROP` statement of the table name that the user provided, risking destruction of user data.
- Fortunately, the bad scenario was almost impossible, because the `DROP` statement was only issued _if_ we previously checked that the mentioned table _does not exist_ - dropping a nonexistent table does not do any harm.
- It could have been dangerous in a very unlikely scenario that a table was created just between the _existence check_ and the _drop_.
- After the fix the existence check and any modifications are done within a transaction to avoid interference from concurrent modifications, and the DROP is correctly applied to a temporary Enso table instead of the original one.
- Replaced a temporary log with proper simple logging of SQL statements into a file, if an Environment variable is set.
- Used that feature to test that no unexpected statements occur.
- Closes#7749 implementing the in-memory logic.
- Additional complications have surfaced regarding the Database logic, so it has been split off into a separate ticket: #7981
- Fixes#7352 by remembering original value types in type inference mode to be able to reconstruct them for Mixed.
- Added more benchmarks for comparing performance of constructing columns.
- Fixes missing implementations that caused `Table.union` crashing on some type pairs.
- Ensures that `Loss_Of_Integer_Precision` warning is not swallowed when numeric columns are unioned to create a `Float` column.
- Adds test for all of the above cases.
- Allow to output benchmark results to a CSV by setting an environment variable - useful for quickly comparing benchmarks, e.g. in Enso.
- Shuffle a few `from`s into correct places:
- `Day_Of_Week.from` removing `Day_Of_Week_From` module.
- Adding short cut for `http` and `https` in `Data.read` so it calls onto `Data.fetch` giving a single entry point.
- Moved `URI` extensions from `Standard.Base.Data` module into `Standard.Base.Network.Extensions`.
- Added `post` extension for `URI`.
- Added `contains_key` to `JS_Object`.
- Restored `into` in `JS_Object`:
- Follows old logic populating a constructor.
- Will use conversion from `JS_Object` if present.
- Added automatic deserialization of `Date`, `Time_Of_Day` and `Date_Time` from JSON.
- Uses conversion from `JS_Object`.
- Added conversion from `Text` to a `HTTP_Method` and type checking where `HTTP_Method` used in public APIs.
- Added support for `Date`, `Time_Of_Day` and `Date_Time` in `Table.from_objects`.
- Added `expand_column` to `Table` to expand `JS_Object` to values.
- Add type checking for `Table` in `right` arguments (allowing `Column`s to be used).
- Use type checking in `Table.set` to allow for conversion to a `Column`.
- Remove some unused imports.
- Fix for bug in S3 edge case.
- Closes#7461 by introducing a `Date_Time_Formatter` type and making parsing date time formats more robust and safer.
- The default ('simple') set of patterns is slightly simplified and made case insensitive (except for `M/m` and `H/h`) to avoid the `YYYY` vs `yyyy` issues and make it less error prone.
- The `YYYY` now has the same meaning as `yyyy` in simple mode. The old meaning (week-based year) is moved to a _separate mode_, triggered by `Date_Time_Formatter.from_iso_week_date_pattern`.
- Full Java syntax, as well as custom-built Java `DateTimeFormatter` can also be used by `Date_Time_Formatter.from_java`.
- Text-based constants (e.g. `ISO_ZONED_DATE_TIME`) have now become methods on `Date_Time_Formatter`, e.g. `Date_Time_Formatter.iso_zoned_date_time`).
- Fixes#7354
- And also closes#7712
- Refactors how we handle numeric ops - ensuring that the 'kernels' are placed all in one place and selected based on storage types.
- Closes#7238
- Aligns `update_database_table` to a more consistent and clearer API - `update_rows`.
- Adds a `truncate_table` helper function, to pair up with `drop_table`. Both are `PRIVATE` for now.
- Adds tests for NULLs in keys in `update_rows` and `delete_rows`.
- The behaviour is sometimes unexpected, so instead these fail with `Null_Values_In_Key_Columns`.
- Adds a workaround for https://github.com/oracle/graal/issues/7359
- Adds a workaround for a related bug where a stack frame has no name (its `rootNode.getName() == null`).
- I could not track down this bug to provide a neat repro.
- Closes#7633
- Moves `Round_Spec.enso` from published `Standard.Test` into our `test/Tests` project; the `Table_Tests` that depend on it, simply `import enso_dev.Tests`.
- Changes the layout of the local libraries directory:
- It used to be `root/<namespace>/<name>`.
- Now it is `root/<dir>` - the namespace and name are now read from `package.yaml` instead.
- Adds the parent directory of the current project to the default `ENSO_LIBRARY_PATH`.
- It is treated as a secondary path, so the default `ENSO_HOME/lib` still takes precedence.
- This allows projects to reference and load 'sibling' projects easily - the only requirement is for the project to enable `prefer-local-libraries: true` or add the other local project to its edition. The edition resolution logic is **not changed**.
- Closes#6111
- Aligns semantics of handling Mixed columns.
- Now, if an operation like `iif` or `fill_nothing` is given a `Mixed` column, the result will also be `Mixed` regardless of the `inferred_precise_value_type`.
- Enables a few old tests that were pending but could be enabled since the types work is advanced enough.
- Update list of groups to agreed list.
- Lower case `ALIAS` names to be consistent with function names.
- Add `GROUP` to methods.
- All constructors and functions have doc comments.
- Correct a few typos (e.g. `PRVIATE`).
- Mark some more things as `PRIVATE`.
- Use `ToDo:` and `Note:` consistently.
- Order tags in doc comment.
# Important Notes
We don't have all the doc comments on types and will want to add them in future,
- Closes#5159
- Now data downloaded from the database can keep the type much closer to the original type (like string length limits or smaller integer types).
- Cast also exposes these types.
- The integers are still all stored as 64-bit Java `long`s, we just check their bounds. Changing underlying storage for memory efficiency may come in the future: #6109
- Fixes#7565
- Fixes#7529 by checking for arithmetic overflow in in-memory integer arithmetic operations that could overflow. Adds a documentation note saying that the behaviour for Database backends is unspecified and depends on particular database.
Closes#7353
I introduce a new type `WithAggregatedProblems`, because `WithProblems` was too simple - it only allowed to hold a `List<Problem>` but `AggregatedProblems` is more than that. Ideally we shouldn't multiply entities like this too much. We should probably unify all to use `WithAggregatedProblems` - but after starting this, I realised it will likely just take too much effort to do for this little PR. So instead, I created a follow-up task for this: #7514
