- 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.
* Add Text.substring function and get_position helper function
For #7876 adds a Text.substring function which supports negative indexes and returns a part of a string from 0-based index 'start' and continuing for 'length'
* added substring and simplified get function
For #7876 adds a Text.substring function which supports negative indexes and returns a part of a string from 0-based index 'start' and continuing for 'length'.
Also simplified get function as it looped unnecessarily.

* Transform Range.iterate test to a benchmark
a) it slows down regular unit testing
b) it is not a unit test
c) it behaves like a benchmark
So it should be a benchmark.
* missing Range import
- 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`).
- Added a `FileSystemSPI` allowing protocol resolution to a target type.
- Separated `Input_Stream` and `Output_Stream` from `File` to allow use in other spaces.
- `File_Format` types `read_web` changed to be `read_stream` working with `InputStream`.
- Added directory listing to `Auto_Detect` allowing for `Data.read` to list a folder.
- Adjusted HTTP to return an `InputStream` not a `byte[]`:
- `Response_Body` adjusted to wrap an `InputStream`.
- Added ability to materialize to either and in-memory vector (<4KB) or a temporary file.
- `Data.fetch` will materialize if not a recognized mime-type.
- Added `HTTP_Error` to handle IO exceptions from the stream.
- `Excel_Format` now supports mime-type and reading a stream.
- `Excel_Workbook` can now get a `Excel_Section` using `read_section`.
- Added S3 APIs:
- `parse_uri`: splits an S3 URI into bucket and key.
- `list_objects`: list the items in a S3 bucket with specified prefix.
- `read_bucket`: list prefixes and keys with a delimiter in a S3 bucket with specified prefix.
- `head`: either head_bucket (tests existance) or head_object API (reads object meta data).
- `get_object`: gets an object from S3 returning as a `Response_Body`.
- Added `S3_File` type acting like a `File`:
- No support for writing in this PR.
- **ToDo:** recursive listing, glob filtering, exists, size.
- Fixed a few invalid type signature line.
- Moved `create` methods for `Postgres_Connection` and `SQLite_Connection` into type instead of module.
- Renamed `Column_Fetcher.Builder` to `Column_Fetcher_Builder`.
- Fixed bug with `select_into` in Dry Run mode creating permanent tables.
**ToDo:** Unit tests.
Closes#7677 by eliminating the _stackoverflow execption_. In general it seems _too adventurous_ to walk members of random foreign objects. There can be anything including cycles. Rather than trying to be too smart in these cases, let's just rely on `InteropLibrary.isIdentical` message.
# Important Notes
Calling `sort` on the `numpy` array no longer yields an error, but the array isn't sorted - that needs a fix on the Python side: https://github.com/oracle/graalpython/issues/354 - once it is in, the elements will be treated as numbers and the sorting happens automatically (without any changes in Enso code).
close#7520
Changelog:
- update: SectionsToBinOp compiler pass produces function application for left sections
- refactor: simplify the registration of builtin methods
- 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.
