When we updated spotless's Java and Kotlin formatter, we changed the underlying
formatting rules.
However, due to spotless ratcheting, these formatting changes don't get applied unless a file
gets touched in a commit.
To avoid future PRs introducing lines of change that aren't related to the intention of the PR,
this is a one-time format of all files.
This updates the GraalVM and Truffle libraries to 2024.1.2.
This also updates the build logic to compile Java sources using Java 21, due to some compile-only dependencies within GraalVM/Truffle using class file version 65. However, the produced artifact is still compatible with Java 17.
This also changes the Gradle build logic to use toolchains, and to test the Java libraries with JDK 17 and 21.
One consequence of this change is that Truffle is no longer shaded within the fat jars.
feat: support for jvm21+ toolchain
feat: support for gradle toolchains
feat: pass -PnativeArch=native to build with -march=native
test: multi-jdk testing support
test: support for jvm-test-suite plugin
test: add tasks to run jpkl eval on multiple jdks
test: make jdk exec tests respect multi-jdk flags and ranges
fix: remove mrjar classes at >jvm17 from fatjars
fix: use jdk21 to run the tests (needed for Unsafe.ensureInitialized)
fix: truffle svm dependency is required after graalvm 24.0.0
fix: warnings for gvm flag usage, renamed truffle svm macro
fix: build with --add-modules=jdk.unsupported where needed
fix: don't use gu tool for modern graalvm versions
fix: catch Throwable instead of deprecated-for-removal ThreadDeath
chore: buildinfo changes for JVM targets, toolchains
chore: enforce testing at exactly jdk21
chore: enforce build tooling at jdk21+
chore: bump graalvm/truffle libs → 24.1.2
chore: toolchains for buildSrc

If the object member is const, it only needs to be executed once, and all children in the prototype chain can use its cached value.
There is a possible other optimization here, not included in this PR: we can avoid adding these values to the child object's cachedMembers.
Motivation:
* fix known bugs and limitations of for-generators
* improve code health by removing complex workarounds
Changes:
* simplify AstBuilder code related to for-generators
* track for-generators via `SymbolTable.enterForGenerator()`
* add `RestoreForBindingsNode` during initial AST construction
instead of calling `MemberNode.replaceBody()` later on
* simplify some unnecessarily complex code
* remove workarounds and band-aids such as:
* `isInIterable`
* `executeAndSetEagerly`
* adding dummy slots in `AmendFunctionNode`
* overhaul implementation of for-generators
* store keys and values of for-generator iterations in regular instead of auxiliary frame slots
* set them via `TypeNode.executeAndSet()`
* `ResolveVariableNode` no longer needs to search auxiliary slots
* `Read(Enclosing)AuxiliarySlot` is no longer needed
* at the start of each for-generator iteration, create a new `VirtualFrame`
that is a copy of the current frame (arguments + slots)
and stores the iteration key and value in additional slots.
* execute for-generator iteration with the newly created frame
* `childNode.execute(newFrame)`
* Pkl objects created during the iteration will materialize this frame
* store newly created frames in `owner.extraStorage`
if their for-generator slots may be accessed when a generated member is executed
* resolving variable names to for-generator variables at parse time would make this analysis more precise
* when a generated member is executed,
* retrieve the corresponding frame stored in `owner.extraStorage`
* copy the retrieved frame's for-generator slots into slots of the current frame
Result:
* for-generators are implemented in a correct, reasonably simple, and reasonably efficient way
* complexity is fully contained within package `generator` and `AstBuilder`
* for-generator keys and values can be accessed from all nested scopes:
* key and value expressions of generated members
* condition expressions of nested when-generators
* iterable expressions of nested for-generators
* for-generator keys and values can be accessed from within objects created by the expressions listed above
* sibling for-generators can use the same key/value variable names
* parent/child for-generators can use the same key/value variable names
* fixes https://github.com/apple/pkl/issues/741
- update Kotlin from 1.7.10 to 2.0.21
- Kotlin 1.6 dependencies in Gradle lock files are expected because kotlinc,
which is also used by some tests, internally uses some 1.6 dependencies
for backwards compatibility reasons.
- update kotlinx-html and kotlinx-serialization
- adapt Kotlin code where necessary
- use Kotlin stdlib Path APIs where possible
- fix IntelliJ Kotlin inspection warnings
- reformat code with `./gradlew spotlessApply`
- ktfmt adds lots of trailing commas
- Add workaround to fix IntelliJ "unresolved reference" errors
Nested jars built by spring boot can possibly represent classpath
resource URIs as "jar:nested:".
This changes Pkl to by default trust them with the same level as
modulepath URIs.
Motivation:
- Perform same exception handling for every implementation of PklRootNode.execute().
- Avoid code duplication.
Changes:
- Change PklRootNode.execute() to be a final method that performs exception handling
and calls abstract method executeImpl(), which is implemented by subclasses.
- Remove executeBody() methods, which served a similar purpose but were more limited.
- Remove duplicate exception handling code.
Result:
- More reliable exception handling.
This should fix known problems such as misclassifying stack overflows
as internal errors and displaying errors without a stack trace.
- Less code duplication.
Motivation:
- simplify implementation of lazy type checking
- fix correctness issues of lazy type checking (#785)
Changes:
- implement listing/mapping type cast via amendment (`parent`) instead of delegation (`delegate`)
- handle type checking of *computed* elements/entries in the same way as type checking of computed properties
- ElementOrEntryNode is the equivalent of TypeCheckedPropertyNode
- remove fields VmListingOrMapping.delegate/typeNodeFrame/cachedMembers/checkedMembers
- fix#785 by executing all type casts between a member's owner and receiver
- fix#823 by storing owner and receiver directly
instead of storing the mutable frame containing them (typeNodeFrame)
- remove overrides of VmObject methods that are no longer required
- good for Truffle partial evaluation and JVM inlining
- revert a85a173faa except for added tests
- move `VmUtils.setOwner` and `VmUtils.setReceiver` and make them private
- these methods aren't generally safe to use
Result:
- simpler code with greater optimization potential
- VmListingOrMapping can now have both a type node and new members
- fewer changes to surrounding code
- smaller memory footprint
- better performance in some cases
- fixes https://github.com/apple/pkl/issues/785
- fixes https://github.com/apple/pkl/issues/823
Potential future optimizations:
- avoid lazy type checking overhead for untyped listings/mappings
- improve efficiency of forcing a typed listing/mapping
- currently, lazy type checking will traverse the parent chain once per member,
reducing the performance benefit of shallow-forcing
a listing/mapping over evaluating each member individually
- avoid creating an intermediate untyped listing/mapping in the following cases:
- `new Listing<X> {...}`
- amendment of `property: Listing<X>`
Motivation:
The following expression evaluates to 2 instead of 1:
new Listing { "value" } { [0 + 0] = "override" }.length
Changes:
- fix length computation in EntriesLiteralNode
- improve `api/listing` tests
- make snippet test failures diffable in IntelliJ
Result:
- fixes https://github.com/apple/pkl/issues/780
- improved dev experience in IntelliJ
This fixes issues when a mapping/listing delegates to another mapping/listing.
The core issue is that `cachedValues` is not guaranteed to be the complete set
of the object's members; they may be stored on the delegate instead.
Therefore, it's not correct compute hash code and equality based on `cachedValues`.
Instead, it's better to use the `getCachedValue()` method, which has the correct
logic for looking up the existing cached value.
- change line numbers from blue to faint to improve legibility on dark backgrounds
- use EnumSet throughout
- move all ANSI classes into package core.util (no need to split them over util and runtime)
- rename AnsiCodingStringBuilder to AnsiStringBuilder
Any thrown Pkl Errors are colored in the simple test report!
Also:
* Refactor `TextFormatter` to be more generic; rename to `TextFormattingStringBuilder`
* Adjust test report slightly (no emojis, add more spacing).
* Introduce `ColorTheme` class.
* Make stack frame descriptors colored as "faint"
Also: this changes the summary so it summarizes _all_ modules, rather than a summary per module.
