- Fix any issues identified by the doc writer.
- Alter all `default_widget` functions: all now take display and all use the type check signature.
- Review widgets on AWS APIs and make sure display is correct.
The ultimate goal is to reduce the method calls necessary for `Vector.map`.
# Important Notes
- I managed to reduce the number of Java stack frames needed for each `Vector.map` call from **150** to **22** (See https://github.com/enso-org/enso/pull/11363#issuecomment-2432996902)
- Introduced `Stack_Size_Spec` regression test that will ensure that Java stack frames needed for `Vector.map` method call does not exceed **40**.
- Closes#11227
- Additionally, it should fix#11278 by ensuring that every scheduled message goes to the desired endpoint, by splitting each batch by endpoint.
- Linting updates.
- Add an `Examples.welcome` and adjust the start up project to use it.
- Merge all of Cass's work into the source code.
- Make example render in mono space font.
- Enables the `..` autoscoping style for creating Atoms in expressions.
- Add type checking to methods in columns.
- Auto wrap returns from method in expressions into a column as needed.
- Remove `Time_Period.Day` to remove confusion..
In a sequence of value-level operators, whitespace does not affect relative precedence. Functional operators still follow the space-precedence rules.
The "functional" operators are: `>> << |> |>> <| <<| : .`, application, and any operator containing `<-` or `->`. All other operators are considered value-level operators.
Asymmetric whitespace can still be used to form *operator sections* of value-level operators, e.g. `+2 * 3` is still equivalent to `x -> (x+2) * 3`.
Precedence of application is unchanged, so `f x+y` is still equivalent to `f (x + y)` and `f x+y * z` is still equivalent to `(f (x + y)) * z`.
Any attempt to use spacing to override value-level operator precedence will be caught by the new enso linter. Mixed spacing (for clarity) in value-operator expressions is allowed, as long as it is consistent with the precedences of the operators.
Closes#10366.
# Important Notes
Precedence warnings:
- The parser emits a warning if the whitespace in an expression is inconsistent with its effective precedence.
- A new enso linter can be run with `./run libraries lint`. It parses all `.enso` files in `distribution/lib` and `test`, and reports any errors or warnings. It can also be run on individual files: `cargo run --release --bin check_syntax -- file1 file2...` (the result may be easier to read than the `./run` output).
- The linter is also run as part of `./run lint`, so it is checked in CI.
Additional language change:
- The exponentiation operator (`^`) now has higher precedence than the multiplication class (`*`, `/`, `%`). This change did not affect any current enso files.
Library changes:
- The libraries have been updated. The new warnings were used to identify all affected code; the changes themselves have not been programmatically verified (in many cases their equivalence relies on the commutativity of string concatenation).
- Part of #9486
- Fixes `Table.union`, `merge` and `distinct` tests
- Replaces `distinct_on` in `Context` that was actually a Postgres specific addition leaking into the base with a more abstract `Context_Extension` mechanism.
- This allows us to implement the Snowflake-specific `DISTINCT` using `QUALIFY`.
- Related to #9486
- Fixes types in literal tables that are used throughout the tests
- Tries to makes testing faster by disabling some edge cases, trying batching some queries, re-using the main connection and trying to re-use tables more
- Implements date/time type mapping and operations for Snowflake
- Updates type mapping to correctly reflect what Snowflake does
- Disables warnings for Integer->Decimal coercion as that's too annoying and implicitly understood in Snowflake
- Allows to select a Decimal column with `..By_Type ..Integer` (only in Snowflake backend) because the Decimal column there is its 'de-facto' Integer column replacement.
- Rename `Location.Start` to `Location.Left`.
- Rename `Location.End` to `Location.Right`.
- Use auto-scoping for `Location`.
- Tune widgets for `Text.trim`.
- Correct signature of `Text.split`.
- Adjist `generateLocallyUniqueIdent` to not fail on bad signature.
- Part of #9486
- Fixing our tests to not rely on deterministic ordering of created Tables in Database backends
- Before, SQLite and Postgres used to mostly return rows in the order they were inserted in, but Snowflake does not.
- Fixing various parts of Snowflake dialect.
- Part of #9486
- Building on top of initial work by @jdunkerley and finishing it
- Reverted the changes to the Postgres_Dialect from last Snowflake work and split the Snowflake_Dialect into a separate module.
- Moved from `rounding_decimal_places_not_allowed_for_floats` to `supports_float_round_decimal_places` (as too confusing).
- Added Snowflake_Dialect type.
- Extracted `Snowflake_Spec` into separate `Snowflake_Tests`
- It imports the common tests from `Table_Tests`.
- Some initial adaptations to make the snowflake dialect not-crash.
- Adding `Internals_Access` proxy to allow external implementations to access our internal data structures without directly exposing them to users. Users should not use these.
- Adding profiling of SQL to check performance.
- Always use `Arguments:` for parameters or fields.
- Always use `> Example` for examples.
- Align sections behind `!` or `?` headers.
- Whitespace fixes.
- Closes#9534 by printing the pending groups with pending reason
- Re-introduces original ordering of tests
- Adds a progress bar to the test suite runner in 'interactive' mode (if ANSI colors are enabled, progress bar will also be)
Resolves#9607 by computing `Number.hash` by converting given number to `Float` first and then computing the hash. Also the conversion from `Float.to Decimal` is exact - done via `new BigDecimal(double)`. There is `Decimal.new` that handles the user-friendly conversion. However as a result `Decimal.from 2.1 != Decimal.new 2.1` - that's the only way to ensure consistency between hash code and conversions.
- Closes#9289
- Ensures that we can refer through `Enso_File` to files that do not _yet_ exist - preparing us for implementing the Write functionalities for `Enso_File` (#9291).
- As asked for by @hubertp who was encountering flaky test failures on CI in the Http_Spec and related ones, I'm adding retry logic to make such cases much less likely.
- I've made the test server randomly fail 50% of tests and with the retry logic the tests are still passing, so I think that should be much more robust, in practice the failure rate is much much less (I imagine <1% as most of the time these tests were working and we do a ton of requests in a single CI run).
- I move the `with_retries` method to now be `Test.with_retries` which can be used anywhere in our tests for the retry logic.
- It sleeps for 0.1s between retries. Not all kinds of tests need it, this was mostly for propagation delays in the Cloud in our tests. I was thinking if the delay should be configurable, but I think the 0.1s delay is not problematic and if our tests are sometimes failing due to high machine load, the delay could also help.
- This _does not_ add retry logic to raw HTTP operations or `Data.fetch`. We may add that later, but that needs some further design. In such case we may remove some retries from tests if they become unnecessary.
- Closes#9300
- Now the Enso libraries are themselves capable of refreshing the access token, thus there is no more problems if the token expires during a long running workflow.
- Adds `get_optional_field` sibling to `get_required_field` for more unified parsing of JSON responses from the Cloud.
- Adds `expected_type` that checks the type of extracted fields. This way, if the response is malformed we get a nice Enso Cloud error telling us what is wrong with the payload instead of a `Type_Error` later down the line.
- Fixes `Test.expect_panic_with` to actually catch only panics. Before it used to also handle dataflow errors - but these have `.should_fail_with` instead. We should distinguish these scenarios.
Simplify the `Test.Suite.run_with_filter` to accept a single filter parameter that searches for all the groups and specs that matches that filter. This filter can be a simple text provided from the command line.
# Important Notes
- Pending groups are now printed at the end of the run
- `Test.Suite.run_with_filter` is simplified to accept a single filter parameter that is either `Text` or `Nothing`. See the docs.
- Passing a filter from the command line is therefore straightforward, it is treated as a regex.
- For convenience, I have left all the `main` methods in all the test sources. I have just refactored them to accept the `filter` argument from the command line.
- For example, to run only a single spec from `Vector_Spec.enso`, invoke `enso --run test/Base_Tests/src/Data/Vector_Spec.enso "should allow vector creation with a programmatic constructor"`
- **Majority of the PR is a regex replace** of `^main =` for `main filter=Nothing =` and of `suite.run_with_filter` for `suite.run_with_filter filter`.
- **Fixed some internal engine bugs:**
- `AtomWithHole` allows to specify only one hole - https://github.com/enso-org/enso/pull/9065/files#diff-0f7bb7e85cf86a965de133aa7e6b5958ceb889bd1921c01e00d3a9ceb19626ef
- NaN keys in hash maps are handled in polyglot maps as well - c5257f6c2b78f893214ff67300893b593ea05e21..db4b3c0e9828ee79208d52e02586b24bb845b0d6
