Bump kotlinx-coroutines-core from 1.3.9 to 1.4.0 in /buildSrc

[dependabot[bot]]

Bumps kotlinx-coroutines-core from 1.3.9 to 1.4.0.

Release notes

Sourced from kotlinx-coroutines-core's releases.

1.4.0

Improvements

• StateFlow, SharedFlow and corresponding operators are promoted to stable API (#2316).
• Flow.debounce operator with timeout selector based on each individual element is added (#1216, thanks to @mkano9!).
• CoroutineContext.job extension property is introduced (#2159).
• Flow.combine operator is reworked:
  • Complete fairness is maintained for single-threaded dispatchers.
  • Its performance is improved, depending on the use-case, by at least 50% (#2296).
  • Quadratic complexity depending on the number of upstream flows is eliminated (#2296).
  • crossinline and inline-heavy internals are removed, fixing sporadic SIGSEGV on Mediatek Android devices (#1683, #1743).
• Flow.zip operator performance is improved by 40%.
• Various API has been promoted to stable or its deprecation level has been raised (#2316).

Bug fixes

• Suspendable stateIn operator propagates exception to the caller when upstream fails to produce initial value (#2329).
• Fix SharedFlow with replay for subscribers working at different speed (#2325).
• Do not fail debug agent installation when security manager does not provide access to system properties (#2311).
• Cancelled lazy coroutines are properly cleaned up from debug agent output (#2294).
• BlockHound false-positives are correctly filtered out (#2302, #2190, #2303).
• Potential crash during a race between cancellation and upstream in Observable.asFlow is fixed (#2104, #2299, thanks to @LouisCAD and @drinkthestars).

1.4.0-M1

Breaking changes

• The concept of atomic cancellation in channels is removed. All operations in channels and corresponding Flow operators are cancellable in non-atomic way (#1813).
• If CoroutineDispatcher throws RejectedExecutionException, cancel current Job and schedule its execution to Dispatchers.IO (#2003).
• CancellableContinuation.invokeOnCancellation is invoked if the continuation was cancelled while its resume has been dispatched (#1915).
• Flow.singleOrNull operator is aligned with standard library and does not longer throw IllegalStateException on multiple values (#2289).

New experimental features

• SharedFlow primitive for managing hot sources of events with support of various subscription mechanisms, replay logs and buffering (#2034).
• Flow.shareIn and Flow.stateIn operators to transform cold instances of flow to hot SharedFlow and StateFlow respectively (#2047).

Other

• Support leak-free closeable resources transfer via onUndeliveredElement in channels (#1936).
• Changed ABI in reactive integrations for Java interoperability (#2182).
• Fixed ProGuard rules for kotlinx-coroutines-core (#2046, #2266).
• Lint settings were added to Flow to avoid accidental capturing of outer CoroutineScope for cancellation check (#2038).

External contributions

• Allow nullable types in Flow.firstOrNull and Flow.singleOrNull by @ansman (#2229).
• Add Publisher.awaitSingleOrDefault|Null|Else extensions by @sdeleuze (#1993).
• awaitCancellation top-level function by @LouisCAD (#2213).
• Significant part of our Gradle build scripts were migrated to .kts by @turansky.
